    Lepcha is the oldest and the first tribe reported from Sikkim, India; majority of its population inhabiting in Dzongu valley, an officially demarcated reserve for Lepcha community, bordering Khangchendzonga Biosphere Reserve, in north district. Lepchas of Dzongu are known for their retention of rich cultural heritage. In view of the on-going cultural and economic changes brought in by the process of globalization, the immediate need was felt to document in details the under-explored ethnomedicinal practices of Lepchas of Dzongu valley. This paper reports 118 species, belonging to 71 families and 108 genera, under ethnomedicinal utility by the Lepchas for curing approximately 66 ailments, which could be grouped under 14 broad categories. Zingiberaceae appeared as the most used family (8 species and 5 genera). As per use pattern, maximum of 30.50% species are to cure stomach related disorders/ailments, followed by 19.49% for curing cut, wounds, inflammation, sprains and joint pains. Administration of medicine orally is recorded in 75% cases. Root and rhizome harvesting targeted 30 species. The changing scenario over time both at socio-cultural front and passing traditional knowledge interests from older to younger generation and rich ethnomicinal wealth of the oldest tribe of Sikkim are discussed in the light of conservation strategies and techniques to adopt.

    Background & objectives: Occurrence of chronic physical pain is increasingly identified among youth, and medically unsupervised analgesic use is a possible risk factor for opioid dependence and other mental diseases in later life. Therefore, the present study was carried out in young student population in Sikkim, India, to explore predictors (including current chronic pain and current analgesic use) of low QoL in youth to identify a subset of population vulnerable to substance use and mental diseases in later life. Methods: The study was conducted in a health university setting in Sikkim, North East India. In this cross-sectional study, 156 participants were enrolled with almost equal number of males and females. Generic instruments for demographics and current analgesic use and SF - 36, for assessment of quality of life (QoL), were used. QoL was measured in general, physical and emotional domains. Presence of chronic physical pain during past four weeks was captured using SF - 36. Results: Almost two-third participants reported presence of current physical pain (69%, n=108); and (14%, n=22) reported current analgesic use for pain. In logistic regression model controlled for age, ethnicity, gender and residence, higher body mass index (BMI) (β=-0.16, P=0.02) and current analgesic use (β=1.6, P=0.006) predicted low QoL in emotional domain (less accomplishment due to emotional problem). Current analgesic use also predicted low QoL in another measure of emotional domain (depressed β=2.0, P=0.001). Interpretation & conclusions: This study identified a subset of participants in their youth with low QoL in emotional domain predicted by current analgesic use and possible overweight problem. Low QoL in more than one emotional domain also identifies possibility of later psychiatric impairment. However, chronic pain did not emerge as a significant predictor of low QoL in emotional domain.

    Glacial lake outburst floods (GLOFs) occur when glacier melt water dammed by a moraine is released in short time. Such floods may lead to disastrous events posing, therefore, a huge threat to human lives and infrastructure. A devastating GLOF in Uttarakhand, India, on 17 July 2013 has led to the loss of all villages in a stretch of 18 km downstream the lake and the loss of more than 5000 lives. The present study evaluates all 16 glacial lakes (with an area >0.1 km²) in the Thangu valley, northern Sikkim (India), eastern Himalaya, with respect to potential threats for the downstream areas. The hazard criteria for the study include slope, aspect and distance of the respective parent glacier, change in the lake area, dam characteristics and lake depth. For the most hazardous lakes, the socio-economic conditions in the downstream areas (settlements and infrastructure) are analysed regarding the impact of potential GLOFs. For the vulnerability analysis, we used various satellite products including LANDSAT, RESOUCESAT-1 and 2, RISAT-1 imageries and ASTER GDEM covering the period from 1977 to 2014. For lake mapping, we applied the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Snow Index (NDSI). A Land Use Land Cover (LULC) map of the study area showing in-situ observations is serving as driving factor for the vulnerability analysis. The results of the study show that almost all evaluated glacial lakes were expanding during the study period (1977-2014). Combining the hazard criteria for the lakes, 5 of the 16 studied glacial lakes are identified as highly hazardous. In the downstream area, there are two villages with 200 inhabitants and an army camp within the zone of highest vulnerability. The identified vulnerability zones may be used by the local authorities to take caution of the threatened villages and infrastructure and for risk analysis for planned future hydropower plants.

    Sikkim, a tiny Himalayan state situated in the north-eastern region of India, records limited research on the climate change. Understanding the changes in climate based on the perceptions of local communities can provide important insights for the preparedness against the unprecedented consequences of climate change. A total of 228 households in 12 different villages of Sikkim, India, were interviewed using eight climate change indicators. The results from the public opinions showed a significant increase in temperature compared to a decade earlier, winters are getting warmer, water springs are drying up, change in concept of spring-water recharge (locally known as Mul Phutnu), changes in spring season, low crop yields, incidences of mosquitoes during winter, and decrease in rainfall in last 10 years. In addition, study also showed significant positive correlations of increase in temperature with other climate change indicators viz. spring-water recharge concept (R (2) = 0.893), warmer winter (R (2) = 0.839), drying up of water springs (R (2) = 0.76), changes in spring season (R (2) = 0.68), low crop yields (R (2) = 0.68), decrease in rainfall (R (2) = 0.63), and incidences of mosquitoes in winter (R (2) = 0.50). The air temperature for two meteorological stations of Sikkim indicated statistically significant increasing trend in mean minimum temperature and mean minimum winter temperature (DJF). The observed climate change is consistent with the people perceptions. This information can help in planning specific adaptation strategies to cope with the impacts of climate change by framing village-level action plan.

    A third of the world rabies burden is in India. The Sikkim Anti-Rabies and Animal Health (SARAH) program is the first state-wide rabies program in India and demonstrates a successful One Health model of dog-mediated rabies elimination. The SARAH program was created in 2006 as a collaboration between the Government of Sikkim and international non-government organizations—Vets Beyond Borders and Fondation Brigitte Bardot. Activities are directed to canine rabies vaccination, humane dog population control, community education, and treatment of sick and injured animals. In 2005, there were 0.74 human rabies deaths per 100,000 (4 deaths) within Sikkim, and from 2006 to 2015, there were no human rabies deaths. In 2016, two human rabies deaths were reported near the West Bengal border region. From 2005 to 2010, the incidence of animal rabies is unknown; from 2010 to 2016, eight cases of animal rabies were reported. Major challenges for the program are continued commitment to rabies control in the face of 0 to low human rabies incidence and the risk of rabies incursions. Effective intersectoral communication between Health, Veterinary, Forestry, and Police officers is essential to enable rapid response to animal bite incidents and possible rabies incursions. An integrated One Health approach needs to be maintained with enhanced active rabies surveillance. Other states must establish similar programs if India is ever to achieve a goal of eliminating dog-mediated human rabies. PMID:28361056

    The Khangchendzonga National Park is a part of the eastern Himalaya global biodiversity hotspot and is located in the Sikkim state of India. Increasing livestock populations coupled with the government policy to ban grazing and its selective implementation resulted in conflict. Hence we undertook this multidisciplinary study involving consultations with traditional resource users, field surveys, and remote sensing. We found that in the greater Himalayan part, over the past 6 decades sheep have been increasingly replaced by yaks (and their crossbreeds), who descend only up to the multilayered temperate and subalpine forests during winter. These forests have been extensively manipulated by the yak herders to increase the fodder availability. In terms of economics and equity in benefit sharing, we found that a few yak herders earn high incomes by maintaining large herds while the sheep and pack animal herders earn subsistence level incomes from small herds. We propose a reduction in yak (and their female crossbreed) numbers with adequate alternative livelihood support for the herders.

    Background: Psychological stress following natural disaster is common. Despite several earthquakes in India, data on evaluation of acute stress among the child victims in the early postdisaster period is scarce. Immediately following a devastating earthquake (6.9 Richter) at Sikkim on September, 18 2011, many children attended North Bengal Medical College, the nearest government tertiary care institution, with unusual stress symptoms. Objective: Evaluation of acute stress symptoms in children in the immediate postearthquake period. Materials and Methods: This was a cross-sectional study done over 4 weeks and includes all the children from 1 to 12 years presenting with unusual physical or behavioral symptoms. Those with major injuries requiring admission were excluded. They were divided into two age groups. For older children (8-12 years) the 8-item Children Impact of Event Scale (CIES) was used for screening of stress. Unusual symptoms were recorded in younger children (1-8 years) as CIES is not validated < 8 years. Result: A total of 84 children (2.66%) out of 3154 had stress symptoms. Maximum attendance was noted in first 3 days (65.47%) and declined gradually. In children ≥ 8 years, 48.78% had psychological stress, which was statistically significant on CIES scores without any gender predilection. Static posturing (41.86%), sleeplessness (32.55%), anorexia (9.30%), recurrent vomiting (13.95%), excessive crying (13.95%), or night-awakenings (4.65%) were found in younger children (n = 43) and three required admission. Conclusion: This study represent the first Indian data showing statistically significant psychological impact in older children (8-12 years) and various forms of physical stress symptoms in young children (1-8 years) following earthquake.

    The Tista River, a major tributary of the Brahmaputra drainage system (Eastern Himalaya) has built a fluvial deposit which extents over 16500 km2. The Tista megafan stands out because of (1) its disproportionate size compared to that of the upstream Tista River catchment (8000 km2), and (2) it has been incised about 50m by the river at the topographic front of the mountain range. Neither the timing of deposition/incision of the megafan sediments, and their potential tectonic or climatic controls have yet been investigated. We use both IRSL and 10Be cosmogenic data to respectively constrain the date of deposition and abandonment of the different lobes of the megafan. We suggest that two distal lobes developed successively downstream from a common proximal lobe. Deposition took place since ~50 ka and incision began at 4.0 +0.6/-0.4 ka at an average rate of 10.5 +0.6/-1.8 mm yr-1. In addition, petrology, isotope geochemistry (ɛNd, 87Sr/86Sr) and chemical composition performed on modern river sands and late-Quaternary megafan sediments allows characterizing (1) provenance variations through time of megafan deposits and their implication for drainage development (2) the weathering history of Sikkim recorded by the megafan deposits. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain and the Tethyan Sedimentary Series, (consistent with high erosion rates identified in north Sikkim at millennial timescale). Variations in provenance and weathering through time recorded by the Tista megafan deposits can be linked to climatic variations with strong monsoonal precipitations penetrating further northward into the southern Tibetan plateau. Tectonic processes seem to play a minor role. Otherwise, we propose as a first hypothesis that the Kosi River has recently (at ~4 ka) captured the upper part of the Tista catchment. That could explain the particular isotopic signature of the Tista megafan deposits, its recent incision, its

    The Darjeeling-Sikkim Himalaya lies in the eastern part of the Himalayan fold-thrust belt (FTB) in a zone of high arc-perpendicular convergence between the Indian and Eurasian plates. In this region two distinct faults form the Main Central thrust (MCT), the structurally higher MCT1 and the lower MCT2; both these faults have translated the Greater Himalayan hanging wall rocks farther towards the foreland than in the western Himalaya. The width of the sub-MCT Lesser Himalayan rocks progressively decreases from the western Himalaya to this part of the eastern Himalaya, and as a result, the width of the FTB is narrower in this region compared to the western Himalaya. Our structural analysis shows that in the Darjeeling-Sikkim Himalaya the sub-MCT Lesser Himalayan duplex is composed of two duplex systems and has a more complex geometry than in the rest of the Himalayan fold-thrust belt. The structurally higher Dating duplex is a hinterland-dipping duplex; the structurally lower Rangit duplex varies in geometry from a hinterland-dipping duplex in the north to an antiformal stack in the middle and a foreland-dipping duplex in the south. The MCT2 is the roof thrust of the Daling duplex and the Ramgarh thrust is the roof thrust of the Rangit duplex. In this region, the Ramgarh thrust has a complex structural history with continued reactivation during footwall imbrication. The foreland-dipping component of the Rangit duplex, along with the large displacement associated with the reactivation of the Ramgarh thrust accounts for the large translation of the MCT sheets in the Darjeeling-Sikkim Himalaya. The growth of the Lesser Himalayan duplex modified the final geometry of the overlying MCT sheets, resulting in a plunge culmination that manifests itself as a broad N-S trending "anticline" in the Darjeeling-Sikkim Himalaya. This is not a "river anticline" as its trace lies west of the Teesta river. A transport parallel balanced cross section across this region has accommodated

    Understanding the relative strengths of tectonic and climatic forcing on erosion at different spatial and temporal scales is important to understand the evolution of orogenic topography. To address this question, we quantified exhumation rates at geological timescales and erosion rates at millennial timescales in modern river sands from 10 sub-catchments of the Tista River drainage basin in the Sikkim Himalaya (northeast India) using detrital apatite fission-track thermochronology and cosmogenic 10Be analyses, respectively. We compare these rates to several potential geomorphic or climatic forcing parameters. Our results show that millennial erosion rates are generally higher and spatially more variable than long-term exhumation rates in Sikkim. They also show strongly contrasting spatial patterns, suggesting that the processes controlling these rates are decoupled. At geological timescales, exhumation rates decrease from south to north, with rates up to 1.2 ± 0.6 mm/yr recorded in southwest Sikkim and as low as 0.5 ± 0.2 mm/yr in the northernmost catchment. Long-term exhumation rates do not correlate with any geomorphic or climatic parameter. We suggest they are tectonically controlled: high rates in southwest Sikkim may be linked to the building of the Lesser Himalaya Rangit Duplex, whereas low rates in north Sikkim are consistent with cessation of extensional exhumation along the South Tibetan Detachment after 13 Ma. The highest apparent erosion rates recorded by cosmogenic nuclides (∼5 mm/yr) occur in catchments spanning the Main Central Thrust Zone, but these appear to be strongly influenced by recent landsliding. High millennial erosion rates (1-2 mm/yr) also occur in north Sikkim and may be climatically driven through strong glacial inheritance of the landscape, as attested by high channel-steepness values close to the maximum extent of glaciers during the Last Glacial Maximum. In contrast, variations in rainfall rate do not seem to strongly influence

    Objective: The present study had been undertaken to investigate the sociodemographic profile of individuals who had committed suicide in Sikkim which may throw light on the vulnerable groups. Materials and Methods: Ten-year suicide data (2006–2015) obtained from Police Headquarters, Crime Branch, Gangtok, have been statistically evaluated to study the sociodemographic profile. Results: The results showed that out of 1604 suicide cases recorded for the past 10 years, 1051 were males (65.5%) and 553 (34.5%) were females. Suicide was found to be common among the age group of 21–30 years (24.4%), Rai community (15.8%), population of rural areas (82.6%), and among the population of eastern districts (50.6%). Hanging (94.8%) was found to be the most common method adopted for suicide. Conclusion: The study provides preliminary information about the vulnerable groups for suicide in the state which may be vital for taking necessary steps for its prevention shortly. PMID:28197004

  13. High-temperature cooling histories of migmatites from the High Himalayan Crystallines in Sikkim, India: rapid cooling unrelated to exhumation?

    The High Himalayan Crystallines (HHCs) provide an excellent natural laboratory to study processes related to crustal melting, crustal differentiation, and the tectonic evolution of mountain belts because partial melting in these rocks occurred under well-defined tectonic boundary conditions (N-S collision of the Indian and the Eurasian plates) and the rocks have not been modified by subsequent metamorphic overprinting. We have used petrogenetic grids, kinetically constrained individual thermobarometry, pseudosection calculations, and reaction histories constrained by textural evidence to determine that the migmatites in the HHC of Sikkim attained peak P-T conditions of 750-800 °C, 9-12 kbar, followed by steep isothermal decompression to 3-5 kbar, and then isobaric cooling to ~600 °C. There may be a trend where rocks to the north [closer to the South Tibetan detachment system (STDS)] attained somewhat higher maximum pressures. The decompression may have been triggered by a reduction in density due to the production of melt (~20 vol%); minor amounts of additional melt may have been produced in individual packages of rock during decompression itself, depending on the exact geometry of the P-T path and the bulk composition of the rock. The stalling of rapid, isothermal exhumation at depths of 10-18 km (3-5 kbar) is related to metamorphic reactions that occur in these rocks. Geospeedometry indicates that at least a two-stage cooling history is required to describe the compositional zoning in all garnets. Both of these stages are rapid (several 100's °C/my between 800 and 600 °C, followed by several 10's °C/my between 600 and 500 °C), but there appears to be a spatial discontinuity in cooling history: Rocks to the south (closer to main central thrust) cooled more slowly than rocks to the north (closer to STDS). The boundary between these domains coincides with the discontinuity in age found in the same area by Rubatto et al. (Contrib Mineral Petrol 165

    For the foreseeable future, the search for evidence of past life in rocks acquired from other planets will be constrained by the amount of sample available and by the fidelity of preservation of any fossils present. What amount of rock is needed to establish the existence of past life? To address this question, we studied a minute amount of rock collected from cherty dolomites of the Proterozoic Buxa Formation in the metamorphically altered tectonically active northeastern Himalaya. In particular, we investigated 2 small petrographic thin sections-one from each of 2 bedded chert horizons exposed in the Ranjit River stratigraphic section northwest of Rishi, Sikkim, India-that together comprise an area of approximately 5 cm(2) (about the size of a US postage stamp) and have a total rock weight of approximately 0.1 g. Optical microscopy, confocal laser scanning microscopy, and Raman spectroscopy and imagery demonstrate that each of the thin sections contains a rich assemblage of 3-dimensionally permineralized organic-walled microfossils. This study, the first report of Proterozoic microfossils in units of the Ranjit tectonic window, demonstrates that firm evidence of early life can be adduced from even a minuscule amount of fossil-bearing ancient rock.

    Autochthonous strains of Saccharomyces cerevisiae from traditional starters used for the production of rice-based ethnic fermented beverage in North East India were examined for their genetic polymorphism using mitochondrial DNA-RFLP and electrophoretic karyotyping. Mitochondrial DNA-RFLP analysis of S. cerevisiae strains with similar technological origins from hamei starter of Manipur and marcha starter of Sikkim revealed widely separated clusters based on their geographical origin. Electrophoretic karyotyping showed high polymorphism amongst the hamei strains within similar mitochondrial DNA-RFLP cluster and one unique karyotype of marcha strain was widely distributed in the Sikkim-Himalayan region. We conceptualized the possibility of separate domestication events for hamei strains in Manipur (located in the Indo-Burma biodiversity hotspot) and marcha strains in Sikkim (located in Himalayan biodiversity hotspot), as a consequence of less homogeneity in the genomic structure between these two groups, their clear separation being based on geographical origin, but not on technological origin and low strain level diversity within each group. The molecular markers developed based on HinfI-mtDNA-RFLP profile and the chromosomal doublets in chromosome VIII position of Sikkim-Himalayan strains could be effectively used as geographical markers for authenticating the above starter strains and differentiating them from other commercial strains.

  16. Natural and human impact on the land use and soil properties of the Sikkim Himalayas piedmont in India.

    Natural and human causes of change in land use and soil properties were studied in the Sikkim Himalayas piedmont over the last 150 years, with a special emphasis on the period 1930-2010. Analysis of historical reports, combined with the visual interpretation of topographic maps and satellite images, indicates that the land reforms related to the location of tea gardens caused rapid deforestation of the higher elevated terraces in the late 19th century. Continuous population growth between 1930 and 2010 caused a shift in the major land use changes from the terraces to the floodplains. As a consequence, a gradual extension of tea plantation and forestry development helped in stabilizing the land use of the terraces, while the parallel deforestation of mountain catchments and floodplains for rice cultivation intensified fluvial activity. The enlargement of river-channel area by about 42% between 1930 and 2010 excluded a large part of the floodplains from cultivation and increased risk of soil degradation. The replacement of natural forest by monocultural tea and rice cultivation influenced the physical and chemical properties of the soil. Statistically significant changes were observed only in some chemical properties of the topsoil. Tea cultivation reduced the total carbon content by 26% and total nitrogen content by 33% in the surface soil horizon. The influence of rice tillage on the soil properties is masked by the fluvial activity. The combined effect of flooding and rice cultivation is reflected in the lower content of total carbon and nitrogen in the surface of the soil, namely, 76% and 77% respectively. Taking into account the long-term nature of the plantation, the soil still has the capability to support tea production. The productivity of rice depends partly on fertilization levels and partly on the natural deposition of fresh sediment eroded from mountains.

    The North-eastern (NE) India, comprising of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura, possess diverse array of locally adapted non-Basmati aromatic germplasm. The germplasm collections from this region could serve as valuable resources in breeding for abiotic stress tolerance, grain yield and cooking/eating quality. To utilize such collections, however, breeders need information about the extent and distribution of genetic diversity present within collections. In this study, we report the result of population genetic analysis of 107 aromatic and quality rice accessions collected from different parts of NE India, as well as classified these accessions in the context of a set of structured global rice cultivars. A total of 322 alleles were amplified by 40 simple sequence repeat (SSR) markers with an average of 8.03 alleles per locus. Average gene diversity was 0.67. Population structure analysis revealed that NE Indian aromatic rice can be subdivided into three genetically distinct population clusters: P1, joha rice accessions from Assam, tai rices from Mizoram and those from Sikkim; P2, aromatic rice accessions from Nagaland; and P3, chakhao rice germplasm from Manipur [corrected]. Pair-wise FST between three groups varied from 0.223 (P1 vs P2) to 0.453 (P2 vs P3). With reference to the global classification of rice cultivars, two major groups (Indica and Japonica) were identified in NE Indian germplasm. The aromatic accessions from Assam, Manipur and Sikkim were assigned to the Indica group, while the accessions from Nagaland exhibited close association with Japonica. The tai accessions of Mizoram along with few chakhao accessions collected from the hill districts of Manipur were identified as admixed. The results highlight the importance of regional genetic studies for understanding diversification of aromatic rice in India. The data also suggest that there is scope for exploiting the genetic diversity of aromatic and

    2013-01-01

    Background Due to the difficult geographic terrain with lack of roads and transport, the Sikkim State in India finds difficulties in contending the respiratory diseases especially during the rainy seasons. Findings A case–control study was conducted for two months at the Central Referral Hospital of East Sikkim involving 110 individuals in the age group of 10 years and above. Due to feasibility constraints, 55 cases and 55 controls were selected by applying the non-probability sampling method with age and sex matching. The collected data were tabulated and analyzed by using the SPSS (Statistical Package for Social Sciences) version 10.0 for windows. Findings were expressed in terms of proportion, Chi Square Test and Multiple Logistic Regression Analysis. Here, p-value <0.05 was considered as statistically significant. This study revealed that the presence of overcrowding, chronic exposure to allergens, smoking habits, chronic respiratory illnesses within last 5 years, family history of chronic respiratory illnesses and mental illnesses were independently associated with respiratory diseases. Conclusion This study should be replicated in other parts of Sikkim to obtain more confirmatory evidence on determinants of respiratory diseases. PMID:24010571

    Cordyceps sinensis has been described as a medicine in old Chinese medical books and Tibetan medicine. It is a rare combination of a caterpillar and a fungus and found at altitudes above 4500m in Sikkim. Traditional healers and local people of North Sikkim recommend the mushroom, i.e., Yarsa gumba, Keera jhar (C. sinensis) for all diseases either as a single drug or combined with other herbs. The present study was undertaken to collect information regarding the traditional uses of cordyceps in Sikkim. It was found that most local folk healers/traditional healers use cordyceps for the treatment of 21 ailments. A modern literature search was carried out to assess whether the curative effects are valid or just blind faith of local people. Chemical constituents of cordyceps are given and pharmacological and biological studies reviewed. More mechanism-based and disease-oriented clinical studies are recommended. PMID:21731381

The epicenter of the quake was latidude 27.7o North and longitude 88.2o East about 64 km North-West of Gangtok along the junction point of Teesta lineament and Kanchenjunga fault in the North District of Sikkim. The high intensity tremor triggered various types of natural calamities in the form of landslides, road blocks, falling boulders, lake bursts, flash floods, falling of trees, etc. and caused severe damage to life and property of the people in Sikkim. As the earthquake occurred during the monsoon season, heavy rain and landslides rendered rescue operations extremely difficult. Almost all road connectivity and communication network were disrupted. Sikkim experiences landslides year after year, especially during the monsoons and periods of intense rain. This hazard affects the economy of the State very badly. But due to the earthquake, many new and a few reactivated landslides have occurred in the Sikkim Himalaya.

    The Ganga Plain of North India provides an archaeological and skeletal record of semi-nomadic Holocene foragers in association with an aceramic Mesolithic culture. Prior estimates of stature for Mesolithic Lake Cultures (MLC) used inappropriate equations from an American White reference group and need revision. Attention is given to intralimb body proportions and geo-climatic provenance of MLC series in considering the most suitable reference population. Regression equations from ancient Egyptians are used in reconstructing stature for MLC skeletal series from Damdama (DDM), Mahadaha (MDH), and Sarai Nahar Rai (SNR). Mean stature is estimated at between 174 (MDH) and 178 cm (DDM and SNR) for males, and between 163 cm (MDH) and 179 cm (SNR) for females. Stature estimates based on ancient Egyptian equations are significantly shorter (from 3.5 to 7.1 cm shorter in males; from 3.2 to 7.5 cm shorter in females) than estimates using the American White reference group. Revised stature estimates from tibia length and from femur + tibia more accurately estimate MLC stature for two reasons: a) these elements are highly correlated with stature and have lower standard estimates of error, and b) uncertainty regarding methods of measuring tibia length is avoided. When compared with Holocene samples of native Americans and Mesolithic Europeans, MLC series from North India are tall. This aspect of their biological variation confirms earlier assessments and results from the synergistic influence of balanced nutrition from broad-spectrum foraging, body-proportions adapted to a seasonally hot and arid climate, and the functional demands of a mobile, semi-nomadic life-style.

    This article reports the results of 100% household injury surveillance project conducted over a 1-year period in nine contiguous villages with a total population of 22,883 persons in north India. Fourteen trained field workers did the health and injury survey by visiting 16-20 households every day. In this article, we document the epidemiology of injuries among children in rural households. A person was considered injured if the injury prevented the victim from continuing a normal daily routine as understood by the family and the victim. A total of 2029 injury cases were recorded. Children in the age group 0-14 years accounted for 611 (30%) of all injury cases of which 42% were injured at home (28% for >14 years), 35% on roads (30% for >14 years), 8% on farms (31% for >14 years) and 6% on playgrounds. The maximum number of injuries was due to falls (35%). Eighty per cent of the injuries were minor (Abbreviated Injury Scale (AIS) 1), 18% were moderate or serious (AIS 2-3); none were severe (AIS 4) and one child had a critical injury (AIS 5). The injury rates per 100,000 children in different age groups were 5354, 6962 and 8060 for 0-4, 5-9 and 10-14 years per year.

    We use data from local earthquakes (mb ≥ 3.0) recorded by the Sikkim broadband seismograph network to study the frequency dependent attenuation of the crust and uppermost mantle. These events have been relocated using body wave phase data from local and regional seismograms. The decay of coda amplitudes at a range of central frequencies (1 to 12 Hz) have been measured for 74 earthquake-receiver pairs. These measurements are combined to estimate the frequency dependent coda Q of the form Q(f) = Q0fη. The estimated Q0 values range from 80-200, with an average of 123±29; and η ranges from 0.92-1.04, with an average of 0.98±0.04. To study the lateral variation of Q0 and η, we regionalized the measured Q values by combining all the earthquake-receiver path measurements through a back projection algorithm. We consider a single back-scatter model for the coda waves with elliptical sampling and parameterize the sampled area using 0.2° square grids. A nine-point spatial smoothening (similar to spatial Gaussian filter) is applied to stabilize the inversion. This is done at every frequency to observe the spatial variation of Q(f) and subsequently combined to obtain η variations. Results of our study reveal that the Sikkim Himalaya is characterized by low Q0 (80-100) compared to the foreland basin to its south (150-200) and the Nepal Himalaya to its west (140-160). The low Q and high η in Sikkim Himalaya is attributed to extrinsic scattering attenuation from structural heterogeneity and active faults within the crust, and intrinsic attenuation due to anelasticity in the hotter lithosphere beneath the actively deforming mountain belt. Similar low Q and high η values had also been observed in North-West and Garhwal-Kumaun Himalaya.

    STS-56 Earth observation shows of some of the highest mountain peaks in the world taken from Discovery, Orbiter Vehicle (OV) 103, as it passed over India and China. The top of the view shows one of the snow and ice-covered massifs in the great Karakorum Range of north India. A star-shaped peak at top left reaches 23,850 feet. Glaciers can be seen in valleys at these high elevations. The international border between India to the south (top) and China (bottom) snakes left to right along a river near the top of the scene, then veers into the muntains at top left. Larger valleys, despite their elevation (all in excess of 14,000 feet), are occupied by transport routes joining points in India, China and the southern republics of the CIS. The ancient Silk Route between China and the Middle East lies not far to the north (outside the bottom of the frame).

    Hamei and Marcha are mixed dough inocula used as starters for preparation of various indigenous alcoholic beverages in Manipur and Sikkim in India, respectively. These starters are traditionally prepared from rice with wild herbs and spices. Samples of Hamei and Marcha, collected from Manipur and Sikkim, respectively, were analysed for lactic acid bacterial composition. The population of lactic acid bacteria (LAB) was 6.9 and 7.1 Log cfu/g in Hamei and Marcha, respectively. On the basis of phenotypic and genotypic characters, LAB strains isolated from Hamei and Marcha were identified as Pediococcus pentosaceus, Lactobacillus plantarum and Lactobacillus brevis. Technological properties of LAB such as antimicrobial properties, effect on acidification, ability to produce biogenic amines and ethanol, degree of hydrophobicity and enzymatic activities were also performed. Pediococcus pentosaceus HS: B1, isolated from Hamei, was found to produce bacteriocin. None of the strains produced biogenic amines. LAB strains showed a strong acidifying ability and they also produced a wide spectrum of enzymes.

    Collision between the Indian and Eurasian plates since the Eocene (50 Ma) caused the closure of the Neo-Tethys and the underthrusting of India beneath the Tibetan Plateau, generating the 2500 km extended Himalayan belt. The Main Central Thrust (MCT) marks the boundary of the underlying Midland Lower Himalaya metasediments zone (LH) in the south from the overlying high grade metamorphic Higher Himalaya (HH) in the north. Several models considering petrochronology, geothermobarometry and structural geology have been discussed to explain the inverted metamorphic gradient in the LH metasediments without reaching a common agreement. This study investigates the tectonic setting and the timescale of inverted isograds related to crustal-scale thrusting at the MCT in the Sikkim region, northeast India. The aim is to contribute to the understanding of the link between mechanical and thermal evolution of major thrust zones and to clarify the nature and the origin of orogenic heat applying garnet geospeedometry. Garnets provide a sensitive record of metamorphic conditions and are potential chronometer. Their compositional zoning is used as a gauge for rate estimates of element diffusion within the mineral and allows estimating the absolute time of the thermal evolution. Inverse-fitting numerical model considering FRactIonation and Diffusion in GarnEt (FRIDGE) calculates garnet composition profiles by introducing P-T-t paths and bulk-rock composition of a specific sample. P-T conditions were estimated by convectional geothermobarometry supported by phase equilibria modelling and measured garnet chemical compositions. Simulation were compared with measured garnet profiles. Simple step function and FRIDGE preliminary results of Fe-Mg - Ca - Mn garnet fractionation-diffusion modelling indicate very short timescale (between 3 and 6 Ma) for peak metamorphic conditions in the northeast Himalayan collisional system. This duration does not allow thermal re-equilibration. It is an

    The Tista River, a major tributary of the Brahmaputra drainage system (Eastern Himalaya -Sikkim) has recently incised its megafan at the topographic front of the mountain range by 30 meters. Neither the timing of deposition/incision of the megafan sediments, nor the erosion rates of the source areas have yet been investigated in detail. To constrain erosion rates in the hinterland at different temporal scales, we report cosmogenic nuclide (10Be) and thermochronological (apatite fission-track) data on modern river sands and map the results to evidence spatial variations of erosion/exhumation rates in Sikkim. Millennial erosion rates are significantly higher than geological exhumation rates, display stronger spatial variability and a contrasting pattern, suggesting that the processes controlling these rates are decoupled. Strong exhumation rates at geological timescales in southwest Sikkim (1.2 mm.yr-1) may be structurally controlled by uplift of the Lesser Himalayan duplex, while strong erosion rates at millennial scales in north Sikkim (5-6 mm.yr-1) suggest a climatic control. Cosmogenic nuclides were also used to date the onset of incision of the megafan. In addition, isotope geochemistry (ɛNd, 87Sr/86Sr) on modern river sands and late-Quaternary megafan sediments allows characterizing the isotopic signature of the different source areas and constraining variations in provenance of the Tista megafan deposits through time. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain with excursions more influenced by the Lesser Himalaya domain. These results are consistent with the higher erosion rates identified in north Sikkim at millennial timescale. These data provide a new comprehensive view on modern erosion and long-term exhumation of the Sikkim Himalaya. This study will help our knowledge and understanding of erosional processes and sediment fluxes in mountainous environments as a function of climate and tectonics.

    Background: The North Eastern Region in India is endemic for canine heartworm disease but in clinics accurate diagnosis is some times difficult. The aim of the present study was to determine the prevalence of occult infections for heartworm disease in canine in two geographical regions of North Eastern India. Methods: A total of 782 numbers of three categories of dogs namely, working dogs of military and paramilitary forces, pet dogs and stray dogs were screened for the presence of heartworm infection from August 2011 to July, 2012 in Guwahati (Assam) and Aizawl (Mizoram). Conventional, immunological and molecular techniques were followed for this epidemiological study. The criteria to determine the occult heartworm cases were based on the differences between heartworm positive cases in PCR test and antigen ELISA test. Results: The findings revealed an overall 22.69 percent occult case. The working dogs had highest prevalence (60%) followed by pet (29.16%) and stray dogs (17.75%). Conclusion: The highest percentage of occult heartworm infection was present in working dogs maintained under military or paramilitary forces. PMID:27047976

    Rubella virus outbreaks usually occur when a large numbers of susceptible individuals accumulate. The disease presents clinically with fever and maculopapular rash. The present study reports the investigation of rubella outbreak in a modern and well-planned village near Chandigarh, North India. The blood samples were collected from 39 cases with febrile rash and from 15 age and sex matched healthy controls residing in the same locality and subjected for the detection of Rubella IgM and IgG antibodies by Enzyme linked immunosorbent assay. The throat swabs, urine and blood samples from acute cases were also collected and subjected to RT-PCR using the primers targeting the E1 region. The genetic characterization of the rubella virus was carried out to identify the circulating genotypes. In the present outbreak, 13 laboratory confirmed cases were reported. Rubella IgM antibodies were detected in 12/39 (30.7%) patients. Rubella RNA could be detected in 83.3% (5/6) of urine, 22.2% (2/9) of throat swabs, and 8.3% (1/12) of blood samples. The rubella genotype responsible for the present outbreak was identified as genotype 1a. This outbreak highlights the need for the introduction of rubella vaccine in the National Immunization Programme of India to prevent outbreaks and to aim towards the eradication of this disease. This study reports the presence of genotype 1a in North India for the first time and stresses the need for further molecular work to identify the circulating strains of the virus.

    Tuberculosis (TB) is a major public-health problem in India, having the highest number of incident and multidrug-resistant (MDR) TB cases. The study was carried out to appraise the prevalence of first-line anti-TB drug resistance in Mycobacterium tuberculosis (MTB) and its patterns among different types of TB patients from different settings in a province of North India. Of 3,704 clinical specimens, 345 (9.3%) were culture-positive, and drug-susceptibility testing was carried out for 301 MTB strains. A high level of primary and acquired drug resistance of MTB was observed in the region studied, with weighted mean of 10.5% and 28.08%, 12.81% and 29.72%, 17.12% and 29.94%, 11.97% and 27.84%, and 10.74% and 23.54% for rifampicin, isoniazid, streptomycin, ethambutol-resistant and MDR cases respectively. Drug resistance was significantly higher in pulmonary (p=0.014) and acquired drug-resistant TB cases (p<0.001). Any drug resistance (p=0.002) and MDR TB were significantly (p=0.009) associated with HIV-seropositive cases. An urgent plan is needed to continuously monitor the transmission trends of drug-resistant strains, especially MDR-TB strains, in the region. PMID:22283032

    The climatology, amplitude error, phase error, and mean square skill score (MSSS) of temperature predictions from five different state-of-the-art general circulation models (GCMs) have been examined for the winter (December-January-February) seasons over North India. In this region, temperature variability affects the phenological development processes of wheat crops and the grain yield. The GCM forecasts of temperature for a whole season issued in November from various organizations are compared with observed gridded temperature data obtained from the India Meteorological Department (IMD) for the period 1982-2009. The MSSS indicates that the models have skills of varying degrees. Predictions of maximum and minimum temperature obtained from the National Centers for Environmental Prediction (NCEP) climate forecast system model (NCEP_CFSv2) are compared with station level observations from the Snow and Avalanche Study Establishment (SASE). It has been found that when the model temperatures are corrected to account the bias in the model and actual orography, the predictions are able to delineate the observed trend compared to the trend without orography correction.

  16. Writing sex and sexuality: archives of colonial North India.

    2011-01-01

    This article focuses on disparate sites and subjects to reflect on and problematize the relationship between sexuality and the archives in colonial north India. I dwell on how ‘recalcitrant’ and hidden histories of sexuality can be gleaned by not only expanding our arenas of archives, but also by decentering and recasting colonial archives. I do so by specifically investigating some of the “indigenous” writings in Hindi, through texts concerning homosexuality, sex manuals, the writings of a woman ayurvedic practitioner, didactic literature and its relationship to Dalit (outcaste) sexuality, and current popular Dalit literature and its representations of the past. The debate for me here is not about the flaws of archival uses but rather of playing one archive against another, of appropriating many parallel, alternative, official, and popular archives simultaneously to shape a more nuanced and layered understanding of sexuality.

    The present study was conducted to know the smallholder pig production system in tribal areas of Sikkim State, India. Two hundred tribal farmers were selected randomly from the North and East District of the state. Information on socio-economic characteristics of farmers (gender, occupation, educational status, and farming experience), management practices, disease prevalence, and economics in pig production was collected. The study recorded the mean land holding as 1.2 ± 0.8 ha, and the number of pigs per farm was 5.0 ± 0.28. Pigs were mainly kept as a source of income, and 70 % of farmers reared crossbreed pigs. Ninety percent (90 %) of respondents practiced the intensive system of management whereby kitchen wastes along with cooked mixture comprising maize bhusa, mustard oil cake, pseudostem of banana, tuber, stem, and plant leaves were used to feed their animals. About 40.5 % of farmers procured their breeding stock from government farms that had good records and utilized veterinary services like timely vaccination and deworming. The diseases prevalent in the study area were swine fever, diarrhea, helminthoses, sarcoptic mange, pneumonia, etc. The litter sizes at birth (local, 4.3 ± 0.45; crossbreed, 7.2 ± 0.33), at weaning (local, 2.79 ± 0.24; crossbreed, 6.1 ± 0.21), and age at first farrowing (local, 365.39 ± 7.96 days; crossbreed, 337.24 ± 8.79 days) were recorded. Production costs of meat extracted from local and crossbred pigs were 1.08 $/kg and 0.86 $/kg, respectively.

    Rural households in India rely extensively on informal biomedical providers, who lack valid medical qualifications. Their numbers far exceed those of formal providers. Our study reports on the education, knowledge, practices and relationships of informal providers (IPs) in two very different districts: Tehri Garhwal in Uttarakhand (north) and Guntur in Andhra Pradesh (south). We mapped and interviewed IPs in all nine blocks of Tehri and in nine out of 57 blocks in Guntur, and then interviewed a smaller sample in depth (90 IPs in Tehri, 100 in Guntur) about market practices, relationships with the formal sector, and their knowledge of protocol-based management of fever, diarrhoea and respiratory conditions. We evaluated IPs’ performance by observing their interactions with three patients per condition; nine patients per provider. IPs in the two districts had very different educational backgrounds—more years of schooling followed by various informal diplomas in Tehri and more apprenticeships in Guntur, yet their knowledge of management of the three conditions was similar and reasonably high (71% Tehri and 73% Guntur). IPs in Tehri were mostly clinic-based and dispensed a blend of allopathic and indigenous drugs. IPs in Guntur mostly provided door-to-door services and prescribed and dispensed mainly allopathic drugs. In Guntur, formal private doctors were important referral providers (with commissions) and source of new knowledge for IPs. At both sites, IPs prescribed inappropriate drugs, but the use of injections and antibiotics was higher in Guntur. Guntur IPs were well organized in state and block level associations that had successfully lobbied for a state government registration and training for themselves. We find that IPs are firmly established in rural India but their role has grown and evolved differently in different market settings. Interventions need to be tailored differently keeping in view these unique features. PMID:25012795

  20. Genetic assessment of ornamental fish species from North East India.

    2015-01-25

    Ornamental fishes are traded with multiple names from various parts around the world, including North East India. Most are collected from the wild, due to lack of species-specific culture or breeding, and therefore, such unmanaged collection of the wild and endemic species could lead to severe threats to biodiversity. Despite many regulatory policies, trade of threatened species, including the IUCN listed species have been largely uncontrolled, due to species identification problems arising from the utilization of multiple trade names. So, the development of species-specific DNA marker is indispensable where DNA Barcoding is proved to be helpful in species identification. Here, we investigated, through DNA Barcoding and morphological assessment, the identification of 128 ornamental fish specimens exported from NE India from different exporters. The generated sequences were subjected to similarity match in BOLD-IDS as well as BLASTN, and analysed using MEGA5.2 for species identification through Neighbour-Joining (NJ) clustering, and K2P distance based approach. The analysis revealed straightforward identification of 84 specimens into 35 species, while 44 specimens were difficult to distinguish based on CO1 barcode alone. However, these cases were resolved through morphology, NJ and distanced based method and found to be belonging to 16 species. Among the 51 identified species, 14 species represented multiple trade names; 17 species belonged to threatened category. Species-level identification through DNA Barcoding along with traditional morphotaxonomy reflects its efficacy in regulating ornamental fish trade and therefore, appeals for their conservation in nature. The use of trade names rather than the zoological name created the passage for trafficking of the threatened species and demands immediate attention for sustaining wildlife conservation.

    The objective of this study is to examine the factors that influence the occurrence of childhood anaemia in North-East India by exploring dataset of the Reproductive and Child Health-II Survey (RCH-II). The study population consisted of 10,137 children in the age-group of 0-6 year(s) from North-East India to explore the predictors of childhood anaemia by means of different background characteristics, such as place of residence, religion, household standard of living, literacy of mother, total children ever born to a mother, age of mother at marriage. Prevalence of anaemia among children was taken as a polytomous variable. The predicted probabilities of anaemia were established via multinomial logistic regression model. These probabilities provided the degree of assessment of the contribution of predictors in the prevalence of childhood anaemia. The mean haemoglobin concentration in children aged 0-6 year(s) was found to be 11.85 g/dL, with a standard deviation of 5.61 g/dL. The multiple logistic regression analysis showed that rural children were at greater risk of severe (OR = 2.035; p = 0.003) and moderate (OR = 1.23; p = 0.003) anaemia. All types of anaemia (severe, moderate, and mild) were more prevalent among Hindu children (OR = 2.971; p = 0.000), (OR = 1.195; p = 0.010), and (OR = 1.201; p = 0.011) than among children of other religions whereas moderate (OR = 1.406; p = 0.001) and mild (OR = 1.857; p=0.000) anaemia were more prevalent among Muslim children. The fecundity of the mother was found to have significant effect on anaemia. Women with multiple children were prone to greater risk of anaemia. The multiple logistic regression analysis also confirmed that children of literate mothers were comparatively at lesser risk of severe anaemia. Mother's age at marriage had a significant effect on anaemia of their children as well.

    Introduction: Ulcerative colitis occurs worldwide. It is considered common in most of Europe and North America and uncommon in most of the developing Asian countries. The incidence/prevalence of ulcerative colitis varies not only according to geographical region but also with race and ethnicity. There are no reported data from India on the incidence of the disease and its prevalence. Material and methods: A house to house survey was conducted by questionnaire, formulated to enquire about symptoms that are suggestive of ulcerative colitis. Those with prolonged diarrhoea with or without rectal bleeding were considered as suspected cases. These suspected cases were subjected to video sigmoidoscopy/colonoscopy and rectal biopsy. In addition, patients already diagnosed and receiving treatment for ulcerative colitis, encountered during the survey, were reviewed. Resurvey of the same areas was conducted after a one year interval to detect new cases. Using direct methods, standardised rates were calculated using world standard population weights 22, 18, 16, 12, 12, 9, 7, 3, and 1 for each 10 year age group. Standardised rates were also obtained separately for males, females, and combined populations, using the Punjab state 1991 population census data. Rates were also estimated according to UK 2000 population data. Ninety five per cent confidence intervals (95% CI) of prevalence and incidence rates of ulcerative colitis were estimated under the assumption that the distribution of cases followed a Poisson probability model. Results: A total population of 51 910 were screened from January to March 1999. We identified 147 suspected cases and of these 23 were finally established as ulcerative colitis cases, giving a crude prevalence rate of 44.3 per 100 000 inhabitants (95% CI 29.4–66.6). A second visit to the same areas after one year identified 10 suspected cases in a population of 49 834. Of these, three were confirmed as “definite” ulcerative colitis giving a crude

    Background: Worldwide, the stigma and discrimination impede HIV-AIDS programs across the continuum of prevention to care. We studied stigma and related issues in HIV-positive subjects. Materials and Methods: At a tertiary care hospital in North India, we studied 100 HIV-positive outpatients not receiving antiretroviral therapy. The subjects self-administered ‘Tanzania Stigma Indicator and Community Endline-Individual Questionnaire’. Psychiatric morbidity was screened with General Health Questionnaire (GHQ-I2 Hindi) and diagnosed with Structured Clinical Interview for DSM-IV (SCID). Results: A typical subject was middle aged (25-44 years, 77%), school non-completer (63%), village dweller (61%), and male (59%). Only 35 subjects could differentiate between HIV and AIDS, and only 24 were aware of antiretroviral therapy. Unprotected sex, sharing injections, and blood transfusions were reported spontaneously as possible sources of transmission by 56-79% subjects each. About 80% of subjects reported no fear in touching HIV-positive subjects or their objects. Avoiding injections, being faithful to uninfected partner, avoiding blood transfusions, using condoms, and avoiding sharing razors/blades were reported spontaneously as HIV preventive measures by 40 to 26 subjects each. Half of the subjects blamed self for contracting HIV. Only 38 subjects reported others behaving differently with HIV-positive subjects. HIV status disclosure was reported by 98 subjects (73 to family or relatives). Urban subjects reported higher primary stigma and shame or blame. Psychiatric disorders, present in 45 subjects, showed no association with stigma items. Conclusions: The subjects had a limited knowledge, especially of treatment aspects. Stigma showed no association with psychiatric disorders. The study reflects a strong need for public health measures to enhance awareness and knowledge about HIV/AIDS. PMID:23723539

    The Tista River is a major tributary of the Brahmaputra drainage system (Eastern Himalaya). Its headwaters are located in the glaciated northernmost parts of the Sikkim and its catchment area amounts to more than 12,000 km2 including a depositional megafan (extending mostly in Bangladesh and West Bengal-India). The Tista has recently incised its megafan at the topographic front of the mountain range by about 30 meters. Neither the timing of deposition/incision of the megafan sediments, nor the erosion rates of the source areas as well as their potential relationships, have been investigated in detail. Comparing these data is essential to distinguish between a climatic and/or tectonic control of the evolution of the Sikkim Himalaya and piedmont. To constrain erosion rates in the hinterland at different temporal scales (respectively millenial and geological timescales), we report cosmogenic nuclide (10Be) and thermochronological (apatite fission-tracks) data on modern river sands. Results were mapped to evidence spatial variations of erosion/exhumation rates in the Tista catchment. Cosmogenic nuclides were also used to date the onset of incision of the megafan and relate it to potential changes in hinterland erosion. In addition, isotope geochemistry (ɛNd and 87Sr/86Sr) performed on modern river sands and Late-Quaternary megafan sediments allows characterizing the isotopic signature of the different source areas and constraining variations in provenance of the Tista megafan deposits through time in response to changing climatic conditions. Results show that the Tista fan deposits are mainly sourced from the High Himalayan Crystalline domain with excursions more influenced by the Lesser Himalaya domain. These data provide a new comprehensive view on modern erosion and long-term exhumation of the Sikkim Himalaya. This study of a "closed system" will help our knowledge and understanding of erosional processes and sediment fluxes in mountainous environments as a

    One of the criteria for recommending cholecystectomy for silent gall stones, is gall stones in regions with high incidence of gall bladder cancer. Both gall stones and gall bladder cancer are common in North India. All tertiary care centres in India report high rates of gall bladder cancer (GBC) incidence and poor treatment outcomes in the majority of cases due to advanced stage of presentation. Csendes of Chile has reported very high incidence of gallbladder cancer in Chile and Bolivia and advocated prophylactic cholecystectomy in asymptomatic patients. Incidence rate of gall bladder cancer in Indian males is equal to that of Chile, whereas in females, the rates are almost double the rates of Chile. Indians have also been found to have high concentrations of heavy metals in gall bladder wall, and antibodies to tumor suppressor genes. In India, gall bladder cancer is the commonest GI cancer in women and fourth commonest cancer overall in the female population. In view of the epidemiology and clinical scenario of gall bladder cancer and proven safety of laparoscopic cholecystectomy, there is a need to act before it is too late in the current rates of gall bladder cancer. This study looks at the evidence correlating gall stones and gall bladder cancer, in relation to India. There is pressing evidence today to justify a strategy of prophylactic cholecystectomy in silent gall stones in North India. Data for this study was selected through an internet based search for literature concerning gall stones and gall bladder cancer in India, and for prophylactic cholecystectomy.

    Taenia solium is the major cause of taeniasis and cysticercosis/neurocysticercosis (NCC) in the developing countries including India, but the existence of other Taenia species and genetic variation have not been studied in India. So, we studied the existence of different Taenia species, and sequence variation in Taenia isolates from human (proglottids and cysticerci) and swine (cysticerci) in North India. Amplification of cytochrome c oxidase subunit 1 gene (cox1) was done by polymerase chain reaction (PCR) followed by sequencing and phylogenetic analysis. We identified two species of Taenia i.e. T. solium and Taenia asiatica in our isolates. T. solium isolates showed similarity with Asian genotype and nucleotide variations from 0.25 to 1.01 %, whereas T. asiatica displayed nucleotide variations ranged from 0.25 to 0.5 %. These findings displayed the minimal genetic variations in North Indian isolates of T. solium and T. asiatica.

    The recent earthquake of Mw 6.9 occurred on September 18, 2011 in Sikkim-Nepal border region. The hypocenter parameters determined by the Indian Meteorological Department shows that the epicentre is at 27.7°N, 88.2°E and focal depth of 58Km, located closed to the north-western terminus of Tista lineament. The reported aftershocks are linearly distributed in between Tista and Golapara lineament. The microscopic and geomorphologic studies infer a dextral strike-slip faulting, possibly along a NW-SE oriented fault. Landslides caused by this earthquake are distributed along Tista lineament . On the basis of the aftershock distribution, Kumar et al. (2012), have suggested possible NW orientation of the causative fault plane. The epicentral region of Sikkim bordered by Nepal, Bhutan and Tibet, comprises a segment of relatively lower level seismicity in the 2500km stretch of the active Himalayan Belt. The north Sikkim earthquake was felt in most parts of Sikkim and eastern Nepal; it killed more than 100 people and caused damage to buildings, roads and communication infrastructure. Through this study we focus on the earthquake source parameters and the kinematic rupture process of this particular event. We used tele-seismic body waveformsto determine the rupture pattern of earthquake. The seismic-rupture pattern are generally complex, and the result could be interpreted in terms of a distribution of asperities and barriers on the particular fault plane (Kikuchi and Kanamori, 1991).The methodology we adopted is based on the teleseismic body wave inversion methodology by Kikuchi and Kanamori (1982, 1986 and 1991). We used tele-seismic P-wave records observed at teleseismic distances between 50° and 90° with a good signal to noise ratio. Teleseismic distances in the range between 50° and 90° were used, in order to avoid upper mantle and core triplications and to limit the path length within the crust. Synthetic waveforms were generated gives a better fit with triangular

    Marcha or murcha is a traditional amylolytic starter used to produce sweet-sour alcoholic drinks, commonly called jaanr in the Himalayan regions of India, Nepal, Bhutan, and Tibet (China). The aim of this study was to examine the microflora of marcha collected from Sikkim in India, focusing on yeast flora and their roles. Twenty yeast strains were isolated from six samples of marcha and identified by genetic and phenotypic methods. They were first classified into four groups (Group I, II, III, and IV) based on physiological features using an API test. Phylogenetic, morphological, and physiological characterization identified the isolates as Saccharomyces bayanus (Group I); Candida glabrata (Group II); Pichia anomala (Group III); and Saccharomycopsis fibuligera, Saccharomycopsis capsularis, and Pichia burtonii (Group IV). Among them, the Group I, II, and III strains produced ethanol. The isolates of Group IV had high amylolytic activity. Because all marcha samples tested contained both starch degraders and ethanol producers, it was hypothesized that all four groups of yeast (Group I, II, III, and IV) contribute to starch-based alcohol fermentation.

    We use data from local earthquakes (mb ≥ 3.0) recorded by the Sikkim broad-band seismograph network to study the frequency-dependent attenuation of the crust and uppermost mantle. These events have been relocated using body wave phase data from local and regional seismograms. The decay of coda amplitudes at a range of central frequencies (1 to 12 Hz) has been measured for 74 earthquake-receiver pairs. These measurements are combined to estimate the frequency-dependent coda Q of the form Q( f) = Q0 f η. The estimated Q0 values range from 80 to 200, with an average of 123 ± 29; and η ranges from 0.92 to 1.04, with an average of 0.98 ± 0.04. To study the lateral variation of Q0 and η, we regionalized the measured Q values by combining all the earthquake-receiver path measurements through a back projection algorithm. We consider a single back-scatter model for the coda waves with elliptical sampling and parametrize the sampled area using 0.2° square grids. A nine-point spatial smoothening (similar to spatial Gaussian filter) is applied to stabilize the inversion. This is done at every frequency to observe the spatial variation of Q( f) and subsequently combined to obtain η variations. Results of our study reveal that the Sikkim Himalaya is characterized by low Q0 (80-100) compared to the foreland basin to its south (150-200) and the Nepal Himalaya to its west (140-160). The low Q and high η in Sikkim Himalaya is attributed to extrinsic scattering attenuation from structural heterogeneity and active faults within the crust, and intrinsic attenuation due to anelasticity in the hotter lithosphere beneath the actively deforming mountain belt. Similar low Q and high η values had also been observed in northwest and Garhwal-Kumaun Himalaya.

This paper describes one new species of horsehair worms (Nematomorpha): Chordodes lasuboni and a new record, C. moutoni from North-East India, which raises the total number of described species from India to 17. Chordodes lasuboni is characterized by a novel cuticular pattern in the head region and by the presence of slender, hooked thorn areoles on the body cuticle. Compared to the large size and ecological diversity of India, the nematomorph fauna is regarded as under-sampled and several new species are to be expected.

    Taenia solium taeniasis/cysticercosis is a major public health problem in developing countries. This study reports genotypic analysis of T. solium cysticerci collected from two different endemic areas of North (Chandigarh) and North East India (Dibrugarh) by the sequencing of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The variation in cox1 sequences of samples collected from these two different geographical regions located at a distance of 2585 km was minimal. Alignment of the nucleotide sequences with different species of Taenia showed the similarity with Asian genotype of T. solium. Among 50 isolates, 6 variant nucleotide positions (0.37% of total length) were detected. These results suggest that population in these geographical areas are homogenous.

    Introduction: In North India snake bite deaths are predominantly seen with neurotoxic envenomations (NEs) whereas in South India the hemotoxic envenomation (HE) is more common. Krait is responsible for most deaths in North India. It bites people sleeping on the floors, mostly at night. We describe the profile of venomous snake bites over 1 year in 2013. Materials and Methods: The study was conducted in a rural tertiary care hospital in North India. Demographics, circumstances of bite, envenomation, first aid, delay, consultation, treatment, anti-venom, and outcomes were recorded for all victims of snake bite. We included all consecutive adult (>18 years) venomous snake bite victims admitted from January to December 2013. Results: A total of 91 patients with venomous snake bites were included in the study. Pure NEs were 41 (45.1%), pure HE in 31 (34.1%), 7 (7.7%) had mixed NE + HE, and 12 (13.2%) had only local swelling. Forty patients (44%) were bitten during sleep presenting as NE (92.5%), NE + HE (5%), and HE (2.5%). Findings in the 51 patients (56%) bitten during activity were HE (58.8%), local swelling (23.5%), NE + HE (9.8%), and NE (7.8%) (P < 0.0001). First aid was sought by 24 NE patients out of which 23 (96%) went to alternate practitioners or religious healers. Conclusion: Almost all (97.5%) bites during sleep resulted in NE in our study. About 96% of NE sought first aid from alternate practitioners or religious healers in hope of some magical treatment. Thus, a deadly combination of krait bite during sleep and wrong health seeking behavior is responsible for high mortality krait bites in this region. Mass public awareness regarding krait bites can prevent mortality in many such cases. PMID:27722112

    North Indian Muslim populations have historical, linguistic, and socioreligious significance to the Indian subcontinent. Although sociocultural and political dimensions of their demography are well documented, no detailed genetic structure of the populations is available. We have undertaken a survey of the gene frequencies of the ABO, Rh, PTC taste ability, sickling, and G6PD systems for different endogamous groups: Sheikh, Syed, Pathan, Ansari, Saifi, and Hindu Bania. All the groups at most loci showed statistically nonsignificant differences, except for ABO and PTC traits, for which interpopulational differences were seen. Heterozygosity ranged from 0.048 to 0.617 among the Sheikh, 0.149 to 0.599 among the Pathan, 0.105 to 0.585 among the Ansari, 0.25 to 0.869 among the Syed, 0.107 to 0.565 among the Saifi, and 0.100 to 0.492 among the Hindu Bania. The average D(ST) and G(ST) values for the five marker loci were 0.0625 +/- 0.098 and 0.1072 +/- 0.041, respectively. A dendrogram was constructed using the UPGMA clustering method. Our results revealed that the Pathan and the Sheikh form one cluster, the Syed and the Hindu Bania form another cluster, and the two clusters join together (the so-called higher caste); also, the Saifi and the Ansari form a separate cluster (lower caste). The results of the genetic distance analysis are useful for understanding the pattern of genetic relationships between different endogamous groups of Muslims.

  1. Farmer's response to changing climate in North East India

    Diversification of land use in the cultivation of various crops provides an alternative way to moderate the climate risk. By choosing alternative crops that are resilient to various weather parameters, farmers can reduce the crop damage and achieve optimum output from their limited land resources. Apart from other adaptation measures, crop diversity can reflect farmers' response towards changing climate uncertainty. This paper tries to examine the changing climatic condition through spatio-temporal variation of two important weather variables (precipitation and temperature) in the largest North-East Indian state, Assam, since 1950. It is examined by the variation in crop diversification index. We have used (1) Herfindahl Index for measuring degree of diversification and (2) locational quotient for measuring the changes in the regional crop concentration. The results show that, in almost all the districts, crop specialization has been taking place slowly and that happened mostly in the last phase of our study. The hilly and backward districts recorded more diversification but towards lower value crops. It goes against the normal feature of crop diversification where farmers diversify in favour of high value crops. Employing ordinary least squares method and/or Fixed Effect model, irrigation is found to have significant impact on crop diversification; while the flood plain zones and hill zones are found to have better progress in this regard, which has been due to the survival necessity of poor farmers living the zone. Thus crop diversity does not reflect very significant response from the farmers' side towards changing weather factors (except rainfall) though they have significant impact on the productivity of various crops, and thus profitability. The study thus suggests the necessity for rapid and suitable diversification as alternative climate change mitigation in the long run.

    Using molecular genetic data on Aggarwals (Vaish/Vysya), an endogamous population group of north India, we provide evidence of its homogeneous unstratified population structure. We found the mean average heterozygosity value of 0.33 for 14 single nucleotide polymorphisms belonging to four genes (TCF7L2-, HHEX-, KCNJ11-, and ADIPOQ-) in the Aggarwal population (sample of 184 individuals) and tried to evaluate the genomic efficiency of endogamy in this population with the help of clan-based stratified analysis. We concluded that the sociocultural identity of the endogamous population groups could act as a robust proxy maker for inferring their homogeneity and population structure in India, which is ideal also for population selection for future genome-wide association studies in the country.

    Coccidiosis, caused by apicomplexan parasites of the genus Eimeria, inflicts severe economic losses to the poultry industry around the globe. In the present study, ITS-1 based species specific nested PCR revealed prevalence of E. acervulina, E. brunetti, E. maxima, E. mitis, E. praecox, E. necatrix and E. tenella in 79.2%, 12.5%, 64.6%, 89.6%, 60.4%, 64.6% and 97.9% poultry farms of north India, respectively. The ITS-1 sequences of different Eimeria spp. from north India were generated and analyzed to establish their phylogenetic relationship. The sequence identity with available sequences ranged from 80 to 100% in E. tenella, 95 to 100% in E. acervulina, 64 to 97% in E. necatrix, 96 to 99% in E. brunetti and 97 to 98% in E. mitis. Only long ITS-1 sequences of E. maxima could be generated in the present study and it had 80-100% identity with published sequences. Two out of the four ITS-1 sequences of E. maxima had mismatches in the published nested primer sequences from Australia, while one sequence of E. necatrix had a mismatch near 3' end of both forward and reverse published nested primer sequences, warranting for the need of designing new set of degenerate primers for these two species of Eimeria. In the phylogenetic tree, all isolates of E. acervulina, E. brunetti, E. mitis, E. tenella and E. necatrix clustered in separate clades with high bootstrap value. E. maxima sequences of north Indian isolates grouped in a long form of E. maxima clade. Complete ITS-1 sequences of E. necatrix and E. mitis are reported for the first time from India. Further studies are required with more number of isolates to verify whether these differences are unique to geographical locations.

    Antigen Dd, a polymorphic antigen found in extracts of certain human dandruff specimens, was investigated in five caste groups of north India. The incidence of antigen Dd-positive type varied from 21.21 per cent in Brahmins to 29.08 per cent in the Jat Sikhs of Punjab. However, a high frequency (45%) was observed in the Sunni Muslims of Kashmir, which differed significantly, when compared with different caste groups of Punjab. Family studies on 44 families indicated its inherited nature, the mode of inheritance being autosomal dominant.

    Childhood cancers are relatively uncommon in comparison to adult cancers. There is no literature available to shed light on clinic-pathological types and patterns of care for childhood cancers in our population in North-East India. In this analysis we therefore tried to determine the common childhood cancers diagnosed in our institute, clinical profile of the patients, types of treatment and compliance, and median survival estimates. Leukemia was most common, followed by retinoblastoma, central nervous system tumours and lymphomas. Ascertaining the clinic-pathological profile of childhood cancers in our population is essential for allocation and management of resources for this small but important group of patients.

    2000-04-01

    Selection potential based on differential fertility and mortality has been computed for six tribal groups inhabiting different geo-climatic conditions, namely: Sahariya, Mina and Bhil of the State of Rajasthan, north-western India, and Munda, Santal and Lodha of the State of West Bengal, eastern India. Irrespective of the methodology, the total index of selection was found to be highest among Lodhas (0.668), followed by Sahariyas (0.524), Santals (0.462), Bhils (0.386), Mundas (0.353) and Minas (0.334). Incidentally, Lodha and Sahariya are two of the seventy-four notified primitive tribal groups of India, and these two study populations show the highest index of total selection, mainly because of a higher embryonic and postnatal mortality. The relative contribution of the fertility component to the index of total selection is higher than the corresponding mortality component in all tribal groups. The analysis of postnatal mortality components indicates that childhood mortality constitutes the bulk of postnatal mortality, suggesting that children under 5 years need better health care in these tribal groups.

  8. Tension Among Women in North India: An Idiom of Distress and a Cultural Syndrome.

    PubMed

    Weaver, Lesley Jo

    2017-03-01

    The existing literature on Indian ethnopsychology has long asserted that somatization is a key aspect of experiences of distress. The study of idioms of distress arose out of work done in India (Nichter in Cult Med Psychiatry 5(4):379-408, 1981), but ironically, little subsequent work has systematically explored idioms of distress in this part of the world. This ethnographic study focused on the term tension (tenśan) and its relation to a cultural syndrome among women in urban North India. This syndrome appears to involve rapid-onset anger, irritation, rumination, and sleeplessness as key symptoms. It is often linked to specific circumstances such as domestic conflict and is associated with the stresses of modern urban life. People who report more symptoms of tension had consistently higher scores on the Hopkins Symptoms Checklist-25 for depression and anxiety. In this cultural context where psychiatric care is highly stigmatized, the language of tension can aid providers of mental healthcare (many of whom, in India, are not psychiatrists or psychologists) to identify and communicate effectively with potential patients whose mental healthcare needs might otherwise go unaddressed.

    Context Gender inequality is a long-recognized driver of the HIV epidemic. However, few studies have investigated the association between gender-based power and HIV risk in India, which has the world's third largest HIV epidemic. Methods Population-based data collected in 2003 from 3,385 couples residing in Uttar Pradesh and Uttarakhand, North India, were used to examine associations between gender-based power (wife's autonomy and husband's inequitable gender attitudes) and indicators of couples' HIV risk (whether the husband had had premarital sex with someone other than his eventual spouse, extramarital sex in the past year or STI symptoms in the past year). Structural equation modeling was used to create composite variables for the gender-based power measures and test their associations with HIV risk measures. Results Twenty-four percent of husbands had had premarital sex, 7% had had extramarital sex in the past year and 6% had had STI symptoms in the past year. Structural equation models indicated that wives who reported higher levels of autonomy were less likely than other wives to have husbands who had had extramarital sex in the past year (direct association) and STI symptoms in the past year (indirect association). Moreover, husbands who endorsed more inequitable gender attitudes were more likely than others to report having had premarital sex with someone other than their spouse, which in turn was associated with having had extramarital sex and STI symptoms in the past year. Conclusions If the associations identified in this study reflect a causal relationship between gender-based power and HIV risk behavior, then HIV prevention programs that successfully address inequitable gender roles may reduce HIV risks in North India.

    Compared to the central Himalaya, the seismogenic potential of Bhutan has been enigmatic due to its lower than average background seismicity, the absence of a reliable historical record, and its unusual location near the Shillong plateau, where a Mw=8.1 earthquake in 1897 resulted in ≈10 m of N/S shortening of the Indian plate to its south. The GPS velocity field measured thrice between 2003 and 2012 provides new insights that permit us to constrain details of loading and collisional geometry. We find that a 90±10 km wide décollement below Sikkim and Bhutan is being loaded at rates of 20±2 mm/year. The locking line lies at approximately 20 km depth and, as in the Himalaya to the west, approximately follows the smoothed 3.5 km contour. Convergence across the Shillong plateau is less than 7 mm/yr. The GPS data suggest that the Brahmaputra valley is rotating clockwise at 0.02±0.1 rad/yr, which is inferred to have the effect of reducing the stressing rate in the Aranuchal Himal. Although a small circle closely defines the Himalayan arc west of 87°E, the Sikkim-Bhutan Himalaya can be approximated by a 500 km linear east-west segment between 87°E and 92°E, terminated by a 10°± change in strike near the 1934 rupture in the west, and by a 20° change in strike at the start of the 400-km-long Arunachal Pradesh segment to the east. Paleoseismic studies to the east and west of Bhutan suggest that a great earthquake may have ruptured this 500 km segment of the arc with 18 m of slip c.1100 AD (Kumar et al., 2011) suggesting that the current slip deficit may be close to that which prevailed before the 1100 earthquake. Thus if no intervening great earthquake has occurred in the Bhutan Himalaya since 1100, the 500 km x100 km area Sikkim/Bhutan segment could slip 18 m at present in a 8.6

    The Siyom Valley section in eastern Arunachal Pradesh exposes an inverted metamorphic succession (Nandini & Thakur, 2011), metapelitic assemblages increasing in grade northwards from chlorite, through biotite, garnet-staurolite and kyanite-bearing schist to kyanite-sillimanite migmatite. Grade changes are mostly controlled by shallowly north, and northwest-dipping fault structures. Two textural stages of garnet growth can be identified in the ilmenite-bearing amphibolite facies rocks, staurolite having formed late in, or after, deformation responsible for the main penetrative foliation (S2). Kyanite and rutile inclusions in garnet indicate that their growth in migmatite preceded that of matrix sillimanite, ilmenite and cordierite, though unrecrystallized kyanite is also common in the feldspathic matrix. Preliminary data indicate the pronounced tectonic thinning of metasedimentary protoliths during exhumation, and the probability of a pronounced step in grade in the middle part of the river section. Similarities with sections in the Sikkim (Dasgupta et al., 2004) and western Arunachal Pradesh (Goswami et al., 2009) Himalaya reflect the lateral continuity of the south-vergent thrusts that controlled the exhumation of the high-grade rocks, with debate concerning the location and significance of the Main Central Thrust zone begging protolith and metamorphic age data.

    This study aims to assess the adequacy level of radiological protection systems available in the diagnostic radiology facilities located in three capital cities of North East (NE) India. It further attempts to understand, using a multi-disciplinary approach, how the safety codes/standards in diagnostic radiology framed by the Atomic Energy Regulatory Board (AERB) and the International Atomic Energy Agency (IAEA) to achieve adequate radiological protection in facilities, have been perceived, conceptualized, and applied accordingly in these facilities. About 30 diagnostic radiology facilities were randomly selected from three capitals of states in NE India; namely Imphal (Manipur), Shillong (Meghalaya) and Guwahati (Assam). A semi-structured questionnaire developed based on a multi-disciplinary approach was used for this study. It was observed that radiological practices undertaken in these facilities were not exactly in line with safety codes/standards in diagnostic radiology of the AERB and the IAEA. About 50% of the facilities had registered/licensed x-ray equipment with the AERB. More than 80% of the workers did not use radiation protective devices, although these devices were available in the facilities. About 85% of facilities had no institutional risk management system. About 70% of the facilities did not carry out periodic quality assurance testing of their x-ray equipment or surveys of radiation leakage around the x-ray room, and did not display radiation safety indicators in the x-ray rooms. Workers in these facilities exhibited low risk perception about the risks associated with these practices. The majority of diagnostic radiology facilities in NE India did not comply with the radiological safety codes/standards framed by the AERB and IAEA. The study found inadequate levels of radiological protection systems in the majority of facilities. This study suggests a need to establish firm measures that comply with the radiological safety codes/standards of the

    Malaria is endemic and a major public health problem in north east (NE) region of India and contributes about 8-12 % of India's malaria positives cases. Historical morbidity pattern of malaria in terms of API (Annual Parasite Incidence) in the state of Assam has been used for delineating the malaria incidence hotspots at health sub centre (HSC) level. Strong spatial autocorrelation (p < 0.01) among the HSCs have been observed in terms of API (Annual Parasite Incidence). Malaria incidence hot spots in the state could be identified based on General G statistics and tested for statistical significance. Spatial correlation of malaria incidence hotspots with physiographic and climatic parameters across 6 agro-climatic zones of the state reveals the types of land cover pattern and the range of elevation contributing to the malaria outbreaks. Analysis shows that villages under malaria hotspots are having more agricultural land, evergreen/semi-evergreen forests with abundant waterbodies. Statistical and spatial analyses of malaria incidence showed a significant positive correlation with malaria incidence hotspots and the elevation (p < 0.05) with villages under malaria hotspots are having average elevation ranging between 17 to 240 MSL. This conforms to the characteristics of two dominant mosquito species in the state Anopheles minimus and An. baimai that prefers the habitat of slow flowing streams in the foot hills and in forest ecosystems respectively.

  17. Comparison of Archean and Phanerozoic granulites: Southern India and North American Appalachians

    Archean granulites at the southern end of the Dharwar craton of India and Phanerozoic granulites in the southern Appalachians of North America share an important characteristic: both show continuous transitions from amphibolite facies rocks to higher grade. This property is highly unusual for granulite terranes, which commonly are bounded by major shears or thrusts. These two terranes thus offer an ideal opportunity to compare petrogenetic models for deep crustal rocks formed in different time periods, which conventional wisdom suggests may have had different thermal profiles. The salient features of the Archean amphibolite-to-granulite transition in southern India have been recently summarized. The observed metamorphic progression reflects increasing temperature and pressure. Conditions for the Phanerozoic amphibolite-to-granulite transition in the southern Appalachians were documented. The following sequence of prograde reactions was observed: kyanite = sillimanite, muscovite = sillimanite + K-feldspar, partial melting of pelites, and hornblende = orthopyroxene + clinopyroxene + garnet. The mineral compositions of low-variance assemblages in mafic and intermediate rocks are almost identical for the two granulite facies assemblages. In light of their different fluid regimes and possible mechanisms for heat flow augmentation, it seems surprising that these Archean and Phanerozoic granulite terranes were apparently metamorphosed under such similar conditions of pressure and temperature. Comparison with other terrains containing continuous amphibolite-to-granulite facies transitions will be necessary before this problem can be addressed.

    Ten Citrus (Linnaeus, 1753) species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much difference in the ratio of longest to shortest chromosome in all the species was observed. Three species, Citrus grandis (Osbeck, 1757), Citrus reticulata (Blanco, 1837) and Citrus medica (Linnaeus, 1753) are identified as true basic species from asymmetry studies of karyotypes as they reflect on the primitive nature of their genomes. Citrus indica (Tanaka, 1937)occupies a special taxonomic position within the genus Citrus as a progenitor for other cultivated species.

    Engineering seismoscope data collected at distances less than 300 km for the M 7.7 Bhuj, India, mainshock are compatible with ground-motion attenuation in eastern North America (ENA). The mainshock ground-motion data have been corrected to a common geological site condition using the factors of Joyner and Boore (2000) and a classification scheme of Quaternary or Tertiary sediments or rock. We then compare these data to ENA ground-motion attenuation relations. Despite uncertainties in recording method, geological site corrections, common tectonic setting, and the amount of regional seismic attenuation, the corrected Bhuj dataset agrees with the collective predictions by ENA ground-motion attenuation relations within a factor of 2. This level of agreement is within the dataset uncertainties and the normal variance for recorded earthquake ground motions.

    Aim: Health professionals especially the dental professional are the frequent targets of musculoskeletal disorders (MSD). Complementary and alternative medicine (CAM) can be of some help in managing these MSD especially in. The purpose of this study was to determine the prevalence of CAM therapies as a treatment modality for MSD management among dental professionals of north India. Materials and Methods: Registered dentist of North Indian origin, India (n = 3598) were included in the study. The questionnaire was sent to all the dentists which consisted of the demographic profile, MSD in the past year, CAM therapies utilization and opinion about CAM therapies. Data analysis was done using SPSS version 21 and data were presented in tabular and graphic form. Test of significance was done using chi-square statistics with P < 0.05 considered as significant. Results: A response rate of 80% (n = 2879) was obtained, and all complained of MDS in some or the other part of their life. The use of CAM was reported among 70% (n = 2015) of the dentist who suffered from MSD. Other dentists either used conventional treatment or did not use anything. Conclusion: As the name implies, alternative medical systems is a category that extends beyond a single modality and refers to an entire system of theory and practice that developed separately from conventional medicine. CAM should be subject to rigorous scientific inquiry so that interventions that work are systematically distinguished from those that do not. In addition, the use of CAM treatments should be based on evidence of effectiveness and safety as demonstrated in randomized clinical trials. PMID:26692749

    Aim: We evaluated the distribution HBV genotypes among non-remunerated healthy blood donors in eastern North India. Materials and Methods: During screening of donated blood, 176 consecutive HBsAg positive, samples comprised the study. HBV-DNA was quantitative detected in 150 samples by PCR. HBV genotype was determined by identifying genotype-specific DNA band using nested PCR. Results: Majorities were of age group 31-40 yrs (65.3%). Males (92.7%) outnumbered females (7.3%) and were HbeAg-negative HBsAg carriers. Over all, genotype-A was the most prevalent (54%) followed by D (21.3%). We did not find genotype-G and H. Districts under study, divided into four zones: Zone–I genotype-A was most common (62.3%) followed by D (18.8%); Zone–II genotype–C (41.2%) was more frequent followed by D (20.6% and A (17.7%). Zone–III in adjoining Bihar state close to Zone–I, A was more prevalent (81.8%) followed by B and C (9.1%). In Zone-IV adjoining Zone- II had genotype-A (100%) only. Genotype–D had more sporadic distribution. Genotype-E and F were prevalent in Zone I and II (3/150, 2%). Conclusions: Among blood donors HBV genotype-A followed by D was the most prevalent in eastern North India. Genotype–A had pattern of distribution signifying common focus, while D was more sporadic and C had single large pocket (Zone-II) probably common focus but restricting to particular area. Evidences are suggestive of association of HBV genotype in liver dysfunction. An effective treatment and preventive strategies based of genotypes will reduce the disease burden and increase the blood safety. PMID:21897593

    We present the results of a broadband magnetotelluric survey along a 200-km-long profile across the Sikkim Himalaya. The data were acquired at average station spacing of 5-6 km and transfer functions of 31 sites in 0.01-1000 s period range have been used for 2-D joint inversion of TE and TM modes. The composite model incorporating the effect of transverse strike reveals several features that correlate with the available seismic and kinematic models of the region. A major result of the present study is that the Main Himalayan Thrust forms the base of several resistive blocks within the wedge and that a ramp structure is present south of the Main Central Thrust Zone (MCTZ). Another significant result is that the crust and mantle lithosphere beneath the MCTZ and the Higher Himalayan Crystallines (HHC) seem to be compositionally/geologically different from the lithosphere south of the MCTZ. A steep crustal-scale fault with the Moho offset of 14 km is inferred to be separating these two blocks. The deep crustal seismicity could be related to this fault whereas shallow seismicity can be linked to the deformation within the wedge. The results also reveal the presence of some more conductors. We relate the conductor within the HHC to the sedimentary rocks of the Tethyan sequence exposed in a window about 40 km west of the profile and north of the South Tibetan Detachment System (STDS). The conductor at 90 km profile location is linked to the Gondwana rocks exposed in the Rangit Window. A 4-6 km thick sedimentary layer overlies the basement in the Gangetic foreland basin. We also delineate a sub-crustal conductor at 50-60 km depth beneath the foreland basin at the southern end of the profile, the cause of which is not apparent and needs to be explored.

    and Arakan-Yuma Zone (BAZ) : Qc= 301 f 0.87, Shillong Plateau Zone (SPZ): Qc=126 fo 0.85. It indicates Northeastern India is seismically active but comparing of all zones in the study region the Shillong Plateau Zone (SPZ): Qc= 126 f 0.85 is seismically most active. Where as the Bengal Alluvium and Arakan-Yuma Zone (BAZ) are less active and out of three the Tibetan Plateau Zone (TPZ)is intermediate active. This study may be useful for the seismic hazard assessment. The estimated seismic moments (Mo), range from 5.98×1020 to 3.88×1023 dyne-cm. The source radii(r) are confined between 152 to 1750 meter, the stress drop ranges between 0.0003×103 bar to 1.04×103 bar, the average radiant energy is 82.57×1018 ergs and the strain drop for the earthquake ranges from 0.00602×10-9 to 2.48×10-9 respectively. The estimated stress drop values for NE India depicts scattered nature of the larger seismic moment value whereas, they show a more systematic nature for smaller seismic moment values. The estimated source parameters are in agreement to previous works in this type of tectonic set up. Key words: Coda wave, Seismic source parameters, Lapse time, single back scattering model, Brune's model, Stress drop and North East India.

    Background The north-east Indian states of Manipur and Nagaland are two of the six high HIV prevalence states in the country, and the main route of HIV transmission is injecting drug use. Understanding the pathways to injecting drug use can facilitate early intervention with HIV prevention programs. While several studies of initiation into injecting drug use have been conducted in developed countries, little is known about the situation in developing country settings. The aim of this study was to increase understanding of the contextual factors associated with initiation into injecting drug use in north-east India, and the influence of these factors on subsequent initiation of others. Method In mid 2006 a cross-sectional survey among 200 injecting drug users (IDUs) was undertaken in partnership with local NGOs that provide HIV prevention and care services and advocacy for IDUs in Imphal, Manipur and Dimapur, Nagaland. The questionnaire elicited detailed information about the circumstances of the first injection and the contexts of participants' lives. Demographic information, self-reported HIV status, and details about initiation of others were also recorded. Results Initiation into injecting drug use occurred at 20 years of age. The drugs most commonly injected were Spasmo-proxyvon (65.5%) and heroin (30.5%). In 53.5% cases, a needle belonging to someone else was used. Two-thirds (66.7%) had used the drug previously, and 91.0% had known other IDUs prior to initiation (mean = 7.5 others). The first injection was usually administered by another person (94.5%), mostly a friend (84.1%). Initiation is a social event; 98% had others present (mean = 2.7 others). Almost 70% of participants had initiated at least one other (mean = 5 others). Initiation of others was independently associated with being male and unemployed; having IDU friends and using alcohol around the time of initiation; and having been taught to inject and not paid for the drug at the time of initiation

    The state of Punjab in the North-West part of India has acted as the main passage for all the major human invasions into the Indian subcontinent. It has resulted in the mixing of foreign gene pool into the local populations, which led to an extensive range of genetic diversity and has influenced the genetic structure of populations in Punjab, North-West India. The present study was conducted to examine the genetic structure, relationships, and extent of genetic differentiation in five Indo-European speaking ethnic groups of Punjab. A total of 1021 unrelated samples belonging to Banias, Brahmins, Jat Sikhs, Khatris, and Scheduled castes were analyzed for four human-specific Ins/Del polymorphic loci (ACE, APO, PLAT, and D1) and three restriction fragment length polymorphisms ESR (PvuII), LPL (PvuII), and T2 (MspI) using Polymerase chain reaction (PCR). All the loci were found to be polymorphic among the studied populations. The frequency of the Alu insertion at APO locus was observed to exhibit the highest value (82.6-96.3 %), whereas D1 exhibited the lowest (26.5-45.6 %) among all the ethnic groups. The average heterozygosity among the studied populations ranged from 0.3816 in Banias to 0.4163 in Khatris. The FST values ranged from 0.0418 to 0.0033 for the PLAT and LPL loci, respectively, with an average value being 0.0166. Phylogenetic analysis revealed that Banias and Khatris are genetically closest to each other. The Jat Sikhs are genetically close to Brahmins and are distant from the Banias. The Jat Sikhs, Banias, Brahmins, and Khatris are genetically very distant from the Scheduled castes. Overall, Uniform allele frequency distribution patterns, high average heterozygosity values, and a small degree of genetic differentiation in this study suggest a genetic proximity among the selected populations. A low level of genetic differentiation was observed in the studied population groups indicating that genetic drift might have been small or negligible in shaping

    Abstract Valeriana jatamansi, a medicinally important species of the family Valerianaceae, has been cytologically studied in different geographical areas of North-Western Himalayan region of India. The tetraploid cytotype with chromosome numbers 2n=32 is in conformity with the earlier reports of the species from different parts of the world. An octoploid cytotype (2n=64) makes a new addition for the species on a worldwide basis, whereas the diploid cytotype (2n=16) is new to India have been reported for the first time in India. These cytotypes (2n=16, 32, 64) show significant variations with respect to morphology as well as geographical distribution in the Western Indian Himalayas. Further, anomalous populations have been marked with meiotic abnormalities in the form of cytomixis, chromosomal stickiness, unoriented bivalents, formation of laggards and bridges resulting in abnormal microsporogenesis, and production of heterogeneous-sized fertile pollen grains along with reduced pollen fertility.

    Hepatitis viral infection is a leading cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Over one million people are estimated to be persistently infected with hepatitis C virus (HCV) worldwide. As capsid core protein is the key element in spreading HCV; hence, it is considered to be the superlative target of antiviral compounds. Novel drug inhibitors of HCV are in need to complement or replace the current treatments such as pegylated interferon’s and ribavirin as they are partially booming and beset with various side effects. Our study was conducted to predict 3D structure of capsid core protein of HCV from northern part of India. Core, the capsid protein of HCV, handles the assembly and packaging of HCV RNA genome and is the least variable of all the ten HCV proteins among the six HCV genotypes. Therefore, we screened four phytochemicals inhibitors that are known to disrupt the interactions of core and other HCV proteins such as (a) epigallocatechin gallate (EGCG), (b) ladanein, (c) naringenin, and (d) silybin extracted from medicinal plants; targeted against active site of residues of HCV-genotype 3 (G3) (Q68867) and its subtypes 3b (Q68861) and 3g (Q68865) from north India. To study the inhibitory activity of the recruited flavonoids, we conducted a quantitative structure–activity relationship (QSAR). Furthermore, docking interaction suggests that EGCG showed a maximum number of hydrogen bond (H-bond) interactions with all the three modeled capsid proteins with high interaction energy followed by naringenin and silybin. Thus, our results strongly correlate the inhibitory activity of the selected bioflavonoid. Finally, the dynamic predicted capsid protein molecule of HCV virion provides a general avenue to target structure-based antiviral compounds that support the hypothesis that the screened inhibitors for viral capsid might constitute new class of potent agents but further confirmation is necessary using in vitro and in vivo

    Background: Nearly 14% of children worldwide do not reach their developmental potential in early childhood. The early identification of delays in achieving milestones is critical. The World Health Organization (WHO) has developed normal age ranges for the achievement of motor milestones by healthy children. This study aimed to assess the gross motor developmental achievements and associated factors among children in rural India. Materials and Methods: A cross-sectional study was conducted with rural children in North India. A pretested questionnaire was used to collect the data. The median age at the time of the highest observed milestone was calculated and compared with the WHO windows of achievement. Results: Overall, 221 children aged 4–18 months were included in the study. The median age of motor development exhibited a 0.1–2.1-month delay compared to the WHO median age of motor milestone achievement. The prevalence of the gross motor milestone achievements for each of the six milestones ranged from 91.6% to 98.4%. Developmental delay was observed in 6.3% of the children. After adjusting for different variables, children with birth order of second or more were found to be significantly associated with the timely achievement of gross motor milestones. Conclusion: The apparently healthy children of the rural area of Haryana achieved gross motor milestones with some delay with respect to the WHO windows of achievement. Although the median value of this delay was low, awareness campaigns should be implemented to promote timely identification of children with development delays. PMID:27843845

    Background & objectives: There is paucity of studies on the quality of anticoagulation in neurological patients from India. This study evaluates the quality of oral anticoagulation therapy in neurology patients. Methods: Consecutive patients attending a tertiary care neurology service in north India who were prescribed oral anticoagulant (OAC), were included. Their international normalized ratio (INR) values were prospectively monitored and the earlier INR values of the patients who were already on OAC were retrospectively analyzed. The patients with multi-organ dysfunction, pregnancy and those below 18 yr of age were excluded. The therapeutic INR range was defined as per standard recommendations. The level of anticoagulation, factors interfering with OAC and complications were noted. Results: The results were based on 77 patients with median age 40 yr. Fifty one patients received OAC for secondary stroke prevention, 23 for cerebral venous sinus thrombosis (CVST) and three for deep vein thrombosis (DVT). A total 167.9 person-years of follow up was done with a median of 1.2 (0.3-9.3) years. Of the 1287 INR reports, 505 (39.3%) reports were in the therapeutic range, 496 (38.5%) were below and 282 (21.91%) were above the therapeutic level. Stable INR was obtained in 33 (42.86%) patients only. INR level was improved by dose adjustment in 20 (26%), drug modification in two (2.6%), and dietary adjustment in six (7.8%) patients. Three patients were sensitive and five were resistant to OAC. Complications were noted in 28 instances; thromboembolic in 16 and haemorrhagic stroke in 12. The overall complication rate was 16.7 per 100 person-years. Interpretation & conclusions: It may be concluded that stable therapeutic INR is difficult to maintain in neurological patients. Optimal modification of diet, drug and dose of oral anticoagulant may help in stabilization of INR. PMID:27377498

  11. Genetic and functional analysis of HIV-1 Rev Responsive Element (RRE) sequences from North-India

    PubMed Central

    2010-01-01

    HIV-1 Rev protein regulates the expression of HIV-1 transcripts by binding to a highly structured stem loop structure called the Rev Responsive Element (RRE) present in the genomic and partially spliced RNAs. Genetic variation in this structure is likely to affect binding of Rev protein and ultimately overall gene expression and replication. We characterized RRE sequences from 13 HIV-1 infected individuals from North India which also included two mother-child pairs following vertical transmission. We observed high degree of conservation of sequences, including the 9-nt (CACUAUGGG) long sequence in stem-loop B, required for efficient binding of Rev protein. All of our 13 RRE sequences possessed G to A (position 66) mutation located in the critical branched-stem-loop B which is not present in consensus C or B sequence. We derived a consensus RRE structure which showed interesting changes in the stem-loop structures including the stem-loop B. Mother-Child RRE sequences showed conservation of unique polymorphisms as well as some new mutations in child RRE sequences. Despite these changes, the ability to form multiple essential stem-loop structures required for Rev binding was conserved. RRE RNA derived from one of the samples, VT5, retained the ability to bind Rev protein under in vitro conditions although it showed alternate secondary structure. This is the first study from India describing the structural and possible functional implications due to very unique RRE sequence heterogeneity and its possible role in vertical transmission and gene expression.

    Migrant workers are designated a bridge population in the spread of HIV and therefore if infected, should be diagnosed and treated early. This study examined pathways to HIV diagnosis and access to care for rural-to-urban circular migrant workers and partners of migrants in northern India, identifying structural, social and individual level factors that shaped their journeys into care. We conducted a qualitative study using in-depth interviews with HIV-positive men (n = 20) and women (n = 13) with a history of circular migration, recruited from an antiretroviral therapy centre in one district of Uttar Pradesh, north India. Migrants and partners of migrants faced a complex series of obstacles to accessing HIV testing and care. Employment insecurity, lack of entitlement to sick pay or subsidised healthcare at destination and the household's economic reliance on their migration-based livelihood led many men to continue working until they became incapacitated by HIV-related morbidity. During periods of deteriorating health they often exhausted their savings on private treatments focused on symptom management, and sought HIV testing and treatment at a public hospital only following a medical or financial emergency. Wives of migrants had generally been diagnosed following their husbands' diagnosis or death, with access to testing and treatment mediated via family members. For some, a delay in disclosure of husband's HIV status led to delays in their own testing. Diagnosing and treating HIV infection early is important in slowing down the spread of the epidemic and targeting those at greatest risk should be a priority. However, despite targeted campaigns, circumstances associated with migration may prevent migrant workers and their partners from accessing testing and treatment until they become sick. The insecurity of migrant work, the dominance of private healthcare and gender differences in health-seeking behaviour delay early diagnosis and treatment initiation.

    Anti-glomerular basement (anti-GBM) disease is an uncommon disorder with a bimodal age of presentation. Patients presenting with dialysis-dependent renal failure have poor renal outcomes. There is limited data regarding the clinical presentation and outcomes of anti-GBM disease from India. We conducted this prospective study to analyze the clinical presentation and outcomes of anti-GBM disease at a large tertiary care hospital in North India over 1½ years. Subjects with a biopsy proven anti-GBM disease (light microscopic examination showing crescents and immunofluorescence examination showing linear deposition of IgG) with or without positive anti-GBM antibodies in serum were included in the study and followed-up for at least 12 months. All the patients were treated with steroids, cyclophosphamide, and plasma exchange. A total of 17 patients (nine males) were included. The mean age at presentation was 39.11 ± 16.58 (range 11–72) years. Twelve patients (70%) presented with rapidly progressive glomerulonephritis (RPGN), 4 (23.5%) presented with Goodpasture syndrome, while 1 (5.8%) had nephritic syndrome, 7 (41%) were hypertensive, and 14 (82.3%) required dialysis at the time of presentation. Four patients (23.5%) had associated anti-neutrophil cytoplasmic antibody positivity (anti-myeloperoxidase antibodies in all). Fourteen (87.5%) patients had crescentic glomerulonephritis, while 5 (31.25%) showed necrotizing (n = 4) or granulomatous (n = 1) in the vasculitis. Of 16 patients who received treatment, four (23.25%) achieved complete remission. In this single-center study, the majority of anti-GBM disease patients presented with RPGN and had crescentic glomerulonephritis on biopsy with poor treatment outcome. PMID:28356661

    Over the last half century, the green revolution has transformed India from a famine-prone, drought-susceptible country, into the world's third largest grain producer and one of the most intensely irrigated regions on the planet. This is in no small part due to the country's vast water resources along with an increase in tubewells and more advanced abstraction methods. While agricultural intensification has had undeniable benefits, it has, and continues to have a significant impact on water resources. Unless solutions which take into consideration the ever evolving socio-economic, hydrological and climatic conditions are found, India's agricultural future looks bleak.This research examines the irrigation behaviour of farmers, using data collected during field work in the State of Uttar Pradesh within the Ganges Basin of North India. Significant differences in farmer behaviour and irrigation practices are highlighted, not only between State districts but between individual farmers. This includes the volume of irrigation water applied and the price paid, as well as differences in the yields of crops produced. Analyses of results suggest that this is due to a number of factors, particularly the source of irrigation water. Study areas which had access to cheaper, but crucially less reliable, canal water were found to invest in more efficient water saving technologies in order to reduce the overall cost of irrigation during periods where less expensive canal water is not available. As a result, overall water use and irrigation cost is lower and yields are higher despite very similar climatic conditions. While cheap canal water is not an option for all farmers, the results show that the introduction of more efficient water saving technologies, despite the significant capital expenditure is a viable option for many farmers and costs can be recovered in a relatively short space of time. In addition, the reduction of declining water levels mean that water is abstracted from

    The present study is an attempt to examine possible associations between ABO blood groups and the risk of osteoporosis among postmenopausal women of North India. This cross-sectional study involved 250 postmenopausal women from North India, ranging in age from 45 to 80 years. Four anthropometric measurements (height, weight, waist circumference and hip circumference), blood sample (ABO status and haemoglobin concentration) and grip strength (dominant as well as non-dominant hand) of all the participants were taken. Bone mineral density (BMD) was evaluated by using dual energy X-ray absorptiometry (DXA) at lumbar spine (L1-L4) and proximal femur. Analysis of data revealed that at lumbar spine (L1-L4) osteoporosis was more prevalent among individuals with blood group A (31.58%), followed by those with blood group B (29.67%), AB (28.57%) and then blood group O (15%), whereas for proximal femur individuals with blood group AB (21.43%) showed the highest prevalence of osteoporosis followed by a decreasing trend from blood group A (17.54%) to B (12.08%) and then O (5%). Total prevalence of osteoporosis was 26.4% in lumbar spine and 13.2% in proximal femur, indicating that lumbar spine had an elevated risk for osteoporosis among postmenopausal women. All the anthropometric variables, haemoglobin concentration as well as grip strength of individuals with blood group O demonstrated non-significant differences with non-O blood group except for weight and body mass index, where differences were statistically significant. Women with blood group O exhibited significantly higher bone mineral density for lumbar spine (0.90 g/cm(2) vs. 0.85 g/cm(2), p<0.05) and proximal femur (0.87 g/cm(2) vs. 0.79 g/cm(2), p<0.05) as compared to those with non-O blood group, thereby suggesting an increasing risk of osteoporosis among individuals with non-O blood group.

    Background: Due to wider access to and free antiretroviral therapy (ART) program, the number of children dying due to acquired immune deficiency syndrome (AIDS)-related causes has declined and the nature and duration of human immunodeficiency virus (HIV)/AIDS caregiving has also dramatically altered. The care of children living with HIV/AIDS (CLHA) places a significant additional burden on the caregivers. Aims: This study was conducted to assess the perceived burden among caregivers of children living with HIV in North India. Materials and Methods: A hospital-based cross-sectional study among 156 CLHA-caregiver dyads in North India was conducted from June 2010 to May 2011. Data were collected by using a pretested structured interview schedule. The caregiver burden was measured with a 36-item scale adapted from Burden Assessment Schedule of Schizophrenia Research Foundation (BASS). Child characteristics, caregiver characteristics, caregiving burden, the knowledge of caregivers, and issues related to health care, nutrition, education, and psychological aspects were studied. Results: Caregivers had a mean age of 35.9 ± 10.2 years. Women accounted for over three-fourth (76.9%) of the caregivers. Nearly two-third of them (65.4%) reported as living with HIV. The mean caregiver burden score was 68.7 ± 2.9. A majority of the caregivers reported either low or moderate burden. Standardized percentage score was high in the domains of physical and mental health, external support, patients’ behavior, and caregivers’ strategy and seemed to be comparatively less in the other domains such as support of the patient and taking responsibility. Conclusions: Caring of children is a universal practice but there is a need of special care for children living with HIV. The majority of caregivers who were usually the mothers perceived the burden and need to be assisted in caring for the child. Stigma and discrimination with HIV infection further increased the burden as caregivers did

    This study analysed buffaloes from north-east India and compared their nuclear and mitochondrial DNA variations with buffaloes of mainland India, China, Mediterranean and South-East Asia. Microsatellite genotypes of 338 buffaloes including 210 from six north-east Indian buffalo populations and three mainland Indian breeds were analysed to evaluate their genetic structure and evolutionary relationships. Phylogenetic analysis and multidimensional scaling plot of pairwise FST revealed the clustering of all swamp-type buffaloes of north-east India with Lower Assamese (significantly hybrid type) buffaloes in one plane and all the mainland river buffaloes in another plane while the upper Assamese buffaloes being distinct from both these clusters. Analysis of mtDNA D-loop region of 530-bp length was performed on 345 sequences belonging to 23 buffalo populations from various geographical regions to establish the phylogeography of Indian water buffalo. The swamp buffaloes of north-east India clustered with both the lineages of Chinese swamp buffalo. Multidimensional scaling display of pairwise FST derived from mitochondrial DNA data showed clustering of upper Assamese, Chilika and Mediterranean buffaloes distinctly from all the other Indian buffalo populations. Median-joining network analysis further confirmed the distinctness and ancestral nature of these buffaloes. The study revealed north-east region of India forming part of the wider hybrid zone of water buffalo that may probably extend from north-east India to South-East Asia.

    The great 1934 Himalayan earthquake of moment magnitude (Mw) 8.1 generated a large zone of ground failure and liquefaction in north Bihar, India, in addition to the earthquakes of 1833 (Mw ~7.7) and 1988 (Mw 6.7) that have also impacted this region. Here, we present the results of paleoliquefaction investigations from four sites in the plains of north Bihar and one in eastern Uttar Pradesh. The liquefaction features generated by successive earthquakes were dated at AD 829-971, 886-1090, 907-1181, 1130-1376, 1112-1572, 1492-1672, 1733-1839, and 1814-1854. One of the liquefaction events dated at AD 829-971, 886-1090, and 907-1181 may correlate with the great earthquake of AD ~1100, recognized in an earlier study from the sections across the frontal thrust in central eastern Nepal. Two late medieval liquefaction episodes of AD 1130-1376 and 1492-1672 were also exposed in our sites. The sedimentary sections also revealed sandblows that can be attributed to the 1833 earthquake, a lesser magnitude event compared to the 1934. Liquefactions triggered by the 1934 and 1988 earthquakes were evident within the topmost level in some sections. The available data lead us to conjecture that a series of temporally close spaced earthquakes of both strong and large types, not including the infrequent great earthquakes like the 1934, have affected the Bihar Plains during the last 1500 years with a combined recurrence interval of 124 ± 63 years.

    Indigenous strains of Trichoderma species isolated from rhizosphere soils of Tea gardens of Assam, north eastern state of India were assessed for in vitro antagonism against two important tea fungal pathogens namely Pestalotia theae and Fusarium solani. A potent antagonist against both tea pathogenic fungi, designated as SDRLIN1, was selected and identified as Trichoderma viride. The strain also showed substantial antifungal activity against five standard phytopathogenic fungi. Culture filtrate collected from stationary growth phase of the antagonist demonstrated a significantly higher degree of inhibitory activity against all the test fungi, demonstrating the presence of an optimal blend of extracellular antifungal metabolites. Moreover, quantitative enzyme assay of exponential and stationary culture filtrates revealed that the activity of cellulase, β-1,3-glucanase, pectinase, and amylase was highest in the exponential phase, whereas the activity of proteases and chitinase was noted highest in the stationary phase. Morphological changes such as hyphal swelling and distortion were also observed in the fungal pathogen grown on potato dextrose agar containing stationary phase culture filtrate. Moreover, the antifungal activity of the filtrate was significantly reduced but not entirely after heat or proteinase K treatment, demonstrating substantial role of certain unknown thermostable antifungal compound(s) in the inhibitory activity.

    Human hair is frequently used as a bioindicator of mercury exposure. Mercury (Hg) has for centuries been a useful metal in a variety of applications. Unfortunately, this usefulness is counterbalanced by its neurotoxicological health impact. The US Environmental Protection Agency recommends keeping the hair Hg level <1.0 µg/g. Therefore, an investigation has been performed in order to ascertain the hair Hg levels among the people living at the terai belt of North India. Hair samples were collected from 111 individuals and were placed in an identified plastic bag, stapled to prevent the shift of the hair strand. Samples were analyzed by combustion, gold amalgamation, atomic absorption spectrometry (C-GA-AAS). The mean Hg level in hair was 0.28 µg/g for the whole group ranging from 0.0012 to 1.9091 µg/g. The mean hair Hg levels were 0.16 µg/g for men and 0.12 µg/g for women, indicating that men had higher hair Hg levels than women. Total hair Hg was found to be significantly associated with age, gender and fish consumption frequency. 98 % of the total sample had hair Hg concentrations less than 1.0 µg/g, i.e, within safe dose, whereas only 2 % had Hg concentrations greater than 1.0 µg/g, thereby exceeding the safe dose.

    Background. The pattern of skin morbidity in an area depends on climate, geography, socioeconomic status, nutrition, genetics, and habits of the community. Objective. The objective of the present study was to describe the morbidity profile of patients attending dermatology outpatient department in a tertiary care centre of Garhwal hills, North India. Methodology. This is a record based study carried out using the morbidity registers. Patient details, diagnosis, and treatment provided by physicians were documented in the morbidity register. ICD coding was done to categorize the patients. Results. The total number of new episodes of illnesses treated in the skin outpatient department during 2009–2014 was 47465. Adults (>18 years) constituted about 80.9%. Among adults, about 59.9% were males. Overall the infections of the skin and subcutaneous tissue were the most common (32.6%) followed by the disorders of skin appendages (19.8%), and dermatitis and eczema (18.8%). Of the total patients 16.9% were affected by dermatitis and 16.7% by acne. Psoriasis, urticaria, melasma, and vitiligo were present in 3.4%, 3.4%, 3.6%, and 3.3% patients, respectively. Conclusion. This knowledge will help in planning appropriate range services to meet the patients' needs and help in training of health staff to meet these needs. PMID:27738425

    Sushina nepheline syenite gneisses of Early Proterozoic North Singhbhum Mobile Belt (NSMB), eastern India suffered regional metamorphism under greenschist-amphibolite transitional facies condition. The Agpaitic Sushina nepheline syenite gneisses consist of albite, K-feldspar, nepheline (close to Morozewicz-Buerger composition), aegirine, biotite, epidote, piemontite, sodalite, cancrinite, natrolite and local alkali amphibole. Accessory phases include zircon, hematite, magnetite, rare pyrochlore and occasional eudialyte and manganoan calcic zirconosilicates. Mineral chemistry of albite, K-feldspar, nepheline, aegirine, alkali amphibole, natrolite and zirconium silicate minerals are described. The detailed textural features together with chemical data of some minerals indicate metamorphic overprint of these rocks. A new reaction is given for the genesis of metamorphic epidote. Metamorphic piemontite suggests greenschist facies metamorphism under high fO2 (Hematite-Magnetite buffer). Up to 15.34 mol% of jadeite component in aegirine suggests that the metamorphic grade of the nepheline syenite gneiss reached at least to greenschist-amphibolite transitional facies or higher. Nepheline geothermometry suggests temperature of metamorphism <500 °C, which is consistent with greenschist facies metamorphism of surrounding chlorite-biotite-garnet phyllite country rock.

    ALK gene rearrangement in the lung adenocarcinomas is the second most common (1.6-11.7% of NSCLC) targetable genomic change after EGFR mutations. However, the prevalence and clinicopathological features of ALK-rearranged lung adenocarcinomas from North India are lacking. A total of 240 cases of lung adenocarcinoma were screened for EGFR mutations and for ALK expression. Smoking status, TNM stage, and treatment response were recorded in all cases. Out of 240 cases screened, 37 cases were positive for EGFR mutations and 17 cases (7.08%) showed ALK positivity with immunohistochemistry and break-apart FISH. On excluding 37 EGFR mutation-positive cases, the incidence of ALK-positive adenocarcinoma appears to be higher (17/203 cases, 8.03%). Eight were men and nine were women with mean age of 51.7 years. Majority (62.5%) were non-smokers and had unresectable disease (70.6% stage IV, 17.6% IIIB). The morphological patterns noted were solid (12 cases), papillary (four cases), and micropapillary (one case). Signet ring (two cases) and clear cell change (one cases) were noted. Out of five patients who received crizotinib, three had partial response and two had stable disease. ALK-rearranged lung adenocarcinomas account for a minor proportion of NSCLC with prevalence similar to that reported in literature. However, as contrast to published data in our series, patients were in older age group and had solid and papillary pattern on morphology with an aggressive course.

    2010-11-01

    This paper uses a close reading of villagers' responses to the death in childbirth of a Muslim woman to raise questions about India's current policy emphasis on institutional delivery as a means of reducing maternal mortality. After introducing the context and methods of our research, we describe recent policy interventions related to maternal health, including the National Rural Health Mission established in 2005. We then outline villagers' commentaries on the specific maternal death, focusing on the costs to women's health (and sometimes life) of high fertility; the lack of care available from rural government facilities and staff and the preference for delivering at home with the aid of local practitioners; the financial constraints that make people hesitate to seek medical treatment; and the high costs of private treatment and the poor treatment experienced in government facilities. Our core argument is that government health care provision in rural Uttar Pradesh is embedded in a moral universe characterised by widespread and long-term mistrust of state services and that encouraging institutional deliveries without addressing the perceptions of potential service users is a seriously flawed approach to reducing maternal mortality. The paper draws primarily on ethnographic research funded by the Wellcome Trust during 2002-2005, in a Muslim village in rural Bijnor district (in north-western Uttar Pradesh).

    Background. Classically, each kidney is supplied by a single renal artery originating from abdominal aorta. The present study aimed at its variations and their embryological and clinical correlation. Material and Methods. The formalin-fixed thirty-seven cadavers from north India constituted the material for the study. During routine abdominal dissection conducted for medical undergraduates at the department of anatomy, the kidneys along with their arteries were explored and the morphological variations of renal arteries were noted. Results. We observed supernumerary renal arteries in 23/37 (62.2%) cases (48.6% of aortic origin and 13.5% of renal origin) on the right side and 21/37 (56.8%) cases (45.9% of aortic origin and 10.8% of renal origin) on the left side. Supernumerary renal arteries entered the kidney through hilum, superior pole, and inferior pole. Conclusion. Awareness of variations of renal artery is necessary for surgical management during renal transplantation, repair of abdominal aorta aneurysm, and urological procedures and for angiographic interventions.

  7. A tangled weave: Tracing outcomes of education in rural women's lives in North India

    2015-06-01

    This paper is based on the findings of a research study which traced 56 rural women learners 15 years after they had participated in an empowerment and education programme in North India. It attempts to understand, from the perspectives of women from marginalised communities, the ways in which participating in the programme had been empowering for them, or not. While most of the women were indeed able to transform several areas in their lives, this study illustrates that empowering outcomes cannot be assumed or articulated in categorical terms and that bringing about change requires the negotiation of power at various levels. The women's narratives stand in contrast to the prevalent discourses around women's literacy and empowerment, which highlight the importance of literacy only in terms of its positive impact on attaining development goals. Despite the vigorously discussed de-politicisation of the concept of empowerment, the authors show in this paper that empowerment, when informed by a critical feminist understanding, continues to provide a useful framework to analyse women's experiences related to education, as a process enabling women to understand and negotiate structures of power - which are neither static nor wholly dominating - and to find spaces to exercise agency. There are few longitudinal studies which trace the long-term impact of educational programmes on adult women, and most studies are in the nature of impact assessments of programmes. Through this paper the authors argue for the need to analyse the complexities around the relationship between women's education and empowerment.

    This cross-sectional survey was conducted in two randomly selected villages in Moradabad in North India to demonstrate the association of magnesium status with hypertension in relation to socioeconomic status (SES) in a rural population. There were 1769 subjects (894 males, 875 females) between 25 and 64 years of age, randomly selected and divided into social classes 1-4 depending upon various sociological attributes. The survey methods were a validated questionnaire, blood pressure measurements by mercury manometer, and blood analysis for serum magnesium. Social class 1 and 2 were associated with a greater prevalence of hypertension. The overall prevalence of hypertension diagnosed by JNC-V criteria (> 140/90 mm Hg) was 17.7 per cent (n = 313) and the prevalence was comparable in both sexes and increased with age. Among social class 1 and 2 subjects, there was a higher prevalence of obesity and sedentary lifestyle, a lower intake of dietary magnesium, and a lower serum magnesium compared to social class 3. Logistic regression analysis with adjustment for age showed that SES has a positive relation with hypertension (odds ratio 1.08 men, 1.07 women, P < 0.05), body mass index (odds ratio 1.14 men, 1.13 women, P < 0.01), and sedentary lifestyle (odds ratio 1.38 men, 1.32 women, P < 0.05) in both sexes, and with salt intake in women (odds ratio 1.28, P < 0.05). The odds ratio indicated that a higher intake of magnesium (odds ratio 1.14 men, 1.17 women, P < 0.05) and a higher serum magnesium (odds ratio 1.12 men, 1.15 women, P < 0.05) were associated with a lower risk of hypertension. The findings suggest that social class 1 and 2 subjects in some rural populations of India have a higher prevalence of hypertension and dietary intake of magnesium, and serum magnesium levels were inversely associated with the risk of hypertension.

    Background & objectives: Inhalants are substances whose chemical vapors are inhaled to produce euphoric, disinhibiting, and exciting effects. Data on inhalant abuse in India are relatively scarce. We report the demographic and clinical profile of inhalant users among the treatment seekers at a Drug De-addiction and Treatment Centre in north India. Methods: The records of treatment seekers at the Drug De-addiction and Treatment Centre, over 10 years (2002-2011) were scanned to identify 92 cases reporting inhalant use. Of these 92 cases, the complete record files were available for 87 (94.6%) cases. These case files were reviewed and the relevant data were collected and analyzed. Results: Over the study period of 10 years, the number of cases with inhalant abuse per year rose steadily to peak at 20 cases (4.08% of new cases) in 2006 and then stabilized at 1-3 per cent of new cases annually. Of the 87 cases studied, all were males with a mean age of 18.9±4.12 yr, mean education of 9.8±3.42 yr and mean family income of 7676±7343.15 (median: 5000). Majority of subjects were unmarried (89.7%), urban resident (79.3%), and from a nuclear family (78.2%). About half of the subjects were students (50.6%). The most common inhalant used was typewriter correction fluid (73.6%) followed by typewriter diluent fluid (19.5%) and glue (6.9%). The most common reason for initiation was curiosity. The mean age of onset of inhalant use was 16.3±4.22 yr. Most subjects fulfilled the criteria for inhalant dependence (85.1%). Psychiatric co-morbidity and the family history of substance dependence were present in 26.4 and 32.9 per cent subjects, respectively. Majority of the subjects reported drug related problems, occupation and finance being the worst affected. Interpretations & conclusions: Our results showed that the inhalant users were mostly urban youth belonging to middle socio-economic class families. The principal sources of inhalant abuse were the commonly available substances

    2015-12-01

    Crop burning in the North and Northwestern parts of India started sometime in 1986 when the farmers started using mechanized forming. During October-November and April-May crop residues are burnt which is a serious health threat to people living in the areas and also it impacts climate of the northern parts of India including Himalayan region. Detailed analysis of satellite data, MODIS, AIRS and OMI AURA have been carried out to study aerosol and meteorological parameters near the source of biomass burning and also at far region. During crop burning period, pronounced changes in the aerosol and meteorological parameters are observed at different pressure levels. The emissions from the crop burning are spread in the Indo-Gangetic plains from west-east, over the Himalayan region and over the central parts of India depending upon the wind direction and wind speed. The air quality changes anomalously affecting the visibility and aerosol parameters. The emissions from crop burning mixes with the local emissions (vehicular and industrial sources) affecting the trace gas concentrations and aerosol optical parameters as a result dense haze fog and smog are observed during burning period. Long range transport of emissions from crop burning over India and its various climatic and health consequences will be presented.

    The present work is aimed at the geochronological investigations of the minerals of some granitic rocks and estimation of uranium contents in minerals, rocks and water of some parts of the North-East India with the help of fission track (FT) technique. The study includes FT dating of minerals from granites of four different plutons and from pegmatites of two different regions of Meghalaya, annealing studies of the minerals including the correction of the observed mineral ages and calculation of the cooling and uplift rates of the rocks. Precision on the errors of the mineral ages has also been studied in detail in the present work. The experiment was carried out at the Research laboratories of the Physics and the Geology Departments, Gauhati University, Assam, India during 1981-1984. Experimental results show four different age groups of the minerals which would reflect meaningful geological events in the history of these rocks. Sphenes of the Nartiang and Dawki granites record the highest FT ages ~ 1120 m.y. which may be linked with a major plutonic event. Muscovites of the Nartiang and Jowai pegmatites measure ages ~ 690 m.y. which may correspond to the time of emplacements of these pegmatites. Apatites of the Nartiang granites show FT ages ~ 470 m.y. which falls within the period of Indian Ocean cycle event. But, apatites of the Jowai, Pynursla and Dawki granites record the youngest ages ~ 90 m.y. which lies within the period of extrusion of cretaceous lavas (Sylhet traps). Apatite age of the Nartiang granite and muscovite ages of the Nartiang and Jowai pegmatites were corrected to ~ 510 m.y., ~ 743 m.y. and ~ 741 m.y. respectively by applying the plateau method of age correction. However, insignificant corrections were found in the sphene ages of the Nartiang and Dawki granites and apatite ages of the Jowai and Dawki granites. An interesting finding of the present work is the wide discrepancy between the apatite ages ~ 90 m.y. (Cretaceous) of Jowai, Pynursla

    Objectives This study sought to use a population-based cross-sectional survey to describe depression prevalence, healthcare seeking and associations with socioeconomic determinants in a district in North India. Setting This study was conducted in Sahaspur and Raipur, administrative blocks of Dehradun district, Uttarakhand, in July 2014. Participants A population-based sample of 960 people over the age of 18 years was selected in 30 randomised clusters after being stratified by rural:urban census ratios. Primary outcome measures The survey used a validated screening tool, Patient Health Questionnaire, to identify people with depression, and collected information regarding socioeconomic variables and help-seeking behaviours. Depression prevalence and health seeking behaviours were calculated, and multivariable logistic regression was used to assess associations between risk factors and depression. Results Prevalence of depression was 6% (58/960), with a further 3.9% (37/960) describing a depressive episode of over 2 weeks in the past 12 months. Statistically significant adjusted OR for depression of more than 2 were found for people who were illiterate, classified as Scheduled Caste/Tribe or Other Backward Castes, living in temporary material housing and who had recently taken a loan. While over three quarters of people with depression (79%) had attended a private or government general medical practitioner in the past 3 months, none had received talking therapy (100% treatment gap) and two people (3.3%) had been prescribed antidepressants. Conclusions There are clear associations between social, educational and economic disadvantage and depression in this population. Strategies that address the social determinants of depression, such as education, social exclusion, financial protection and affordable housing for all are indicated. To address the large treatment gap in Uttarakhand, we must ensure access to primary and secondary mental health providers who can

    This is a retrospective study of the experience with extremity vascular trauma at a tertiary level referral centre in North India where the majority of the population lives in villages and the incidence of high-speed automobile accidents and civilian violence is low. The aim was to study the aetiology, pattern of injuries and the mortality and morbidity rates due to vascular trauma in our population. Data relating to 148 patients presenting with vascular trauma requiring surgical intervention other than amputation between January 1996 and December 2002 were collected retrospectively. There were 132 males and 16 females with a mean age of 39 years presenting to the casualty with a median delay of 9.3 h after injury. Blunt trauma accounted for 84% of the injuries with extremities involved in 88%. The brachial artery was the most common artery injured with the femoral next most common. Repair without graft interposition was done in 74% and autogenous vein grafts were used in 23% of cases. Comparison of our results with those that would have been obtained, had the recommendations of Mangled Extremity Severity Score (MESS) been followed, showed that this scoring system had low sensitivity and specificity for prediction of salvageability of limbs. Eight percent patients died due to associated visceral organ injuries. Complications occurred in 32% patients and amputation was required in 6% of patients after an initial surgical repair mainly due to inadequate functional recovery. Eighty-eight percent of the survivors with salvaged limbs were able to achieve full functional recovery. Judicious selection and appropriate intervention can result in satisfactory limb salvage with good functional outcomes even with delayed presentations.

    Columnar aerosol properties retrieved from Multi-Wavelength solar Radiometer (MWR) measurements during the period 2001-2010 over Dibrugarh (27.3°N, 94.6°E, 111 m amsl), North-Eastern India are analyzed to identify the types of aerosols in the atmospheric column. Highest Aerosol optical depth (AOD) characterizes the pre-monsoon (March-May), while lowest AOD has been observed during the post-monsoon (Oct-Nov) season. The Ångström exponent (α) indicates predominance of fine aerosols during post-monsoon and winter (Dec-Feb) and dominance of coarse mode in pre-monsoon and monsoon (June-Sept). NOAA HYSPLIT back trajectory analysis suggests that the seasonal heterogeneity in aerosol characteristics can be attributed to the varying contribution from different source regions. Using the relationship between AOD 500 and α, the aerosols can be classified into five main types viz. continental average (CA), marine continental average (MCA), urban/industrial and biomass burning (UB) and desert dust (DD) while the remaining cases are considered as unidentified or mixed type (MT). These aerosol types exhibit seasonal heterogeneity in their contribution depending upon variability in sources. In winter, local production contributes to observed appreciable CA aerosol type, while highest percentage of UB type is attributed to both local and transported aerosols. On the other hand, transported UB and DD types play a significant role in the pre-monsoon season. Post-monsoon season is indicative of background continental average aerosol condition with a significant contribution from CA and MCA aerosols. Monsoon aerosols couldn't be distinguished properly due to different particle growth processes like humidification, hygroscopic growth etc. and hence MT aerosol type is predominant in this season. This is the first ever attempt to classify aerosols over this environment.

    Introduction Aesthetic and functional problems in the dentofacial complex among children are often attributed to the disturbances in the dentofacial growth and development. This can be recognized during routine dental visits. This study pursued to assess the occlusion of the primary dentition in three to five-year-old children. Aim To study the occlusal traits of the primary dentition in a group of three to five-year-old North Gujarat children of Mehsana district and the variation in their occlusion relative to age and gender in the same group. Materials and Methods The study was a cross-sectional survey based on clinical examination and photographic evaluation of the primary dentition, 383 preschool children aged three to five years who were randomly selected from preschools in Mehsana district, Gujarat, India, using a multistage sampling technique. The study group was evaluated for the several occlusal parameters that include primary molar relation based on Baume classification and canine relation, overjet, overbite were assessed using Foster and Hamilton criteria. Chi-square test was performed to carry out statistical analysis. The p-value<0.05 was taken as statistically significant. Results Out of 383 participants, 55.35% had flush terminal plane; 43.34% mesial step molar relationship and 1.31% distal step molar relationship, 63.2% had straight profile, 95.8% had Class I canine relationship, 71.3% primate spaces, 56.7% physiologic spaces. Flush terminal plane was common at three years while, mesial step at four to five years, and Class I canine relationship was prevalent in both age groups. Flush terminal plane was more common in female participants than the males. Amongst other occlusal characteristics, increased overbite and open bite were prevalent. Conclusion It was found that the flush terminal plane molar relationship, straight profile, Class I canine relationship, primate spacing, increased overbite and open bite predominated. PMID:28274054

    Introduction Elevated oxidative stress plays an important role in the pathogenesis of health disorders, like arthritis. Traditionally, Vespa affinis L., a common edible insect among many tribes in North-East India, is believed to have a beneficial role in extenuating health disorders, such as arthritis. The present study investigated the molecular mechanism underlying medicinal benefit of the Aqueous Extract of Vespa affinis L. (AEVA) against oxidative stress pathophysiology. Methods The free radical scavenging activities of AEVA were examined against DPPH, hydroxyl, and superoxide radicals and the effect on the activities of antioxidant enzyme (GST and CAT) was determined using both recombinant proteins and human plasma. The antioxidant potential of AEVA was again investigated using THP-1 monocytes. Results AEVA possesses a significant free radical scavenging activity as evident from the DPPH, superoxide, and hydroxyl radical scavenging assay. Incubation of AEVA (2.5, 5, 7.5, and 10 μg/μL) with the recombinant antioxidant enzymes, rGST and rCAT significantly increased the enzyme activities compared to those observed in corresponding enzyme alone or AEVA itself. AEVA supplementation (5, 7.5, and 10 μg/μL) also stimulates the activities of GST and CAT when incubated with human plasma. A cell culture study also confirmed the beneficial role of AEVA (0.8 and 1.2 μg/μL) which enhances the activities of GST and CAT, and also reduces the intercellular ROS production in monocytes treated with or without H2O2 and the effects are at par with what is observed in N-acetyl cysteine-treated cells. Conclusion The antioxidant potential of the aqueous extract of Vespa affinis L. may mediate its therapeutic activities in oxidative stress-associated health disorders. PMID:27195807

    Weather forecasting is an important issue in the field of meteorology all over the world. The pattern and amount of rainfall are the essential factors that affect agricultural systems. India experiences the precious Southwest monsoon season for four months from June to September. The present paper describes an empirical study for modeling and forecasting the time series of Southwest monsoon rainfall patterns in the North-East India. The Box-Jenkins Seasonal Autoregressive Integrated Moving Average (SARIMA) methodology has been adopted for model identification, diagnostic checking and forecasting for this region. The study has shown that the SARIMA (0, 1, 1) (1, 0, 1)4 model is appropriate for analyzing and forecasting the future rainfall patterns. The Analysis of Means (ANOM) is a useful alternative to the analysis of variance (ANOVA) for comparing the group of treatments to study the variations and critical comparisons of rainfall patterns in different months of the season.

    the CALIPSO algorithm, probably misclassifying marine aerosol as polluted dust. The origin of much of the polluted dust, the most prominent aerosol species in the region, is the mixing of dust and smoke from Africa. Low-level southerly winds south of 10°N transport smoke northward while northerly winds north of 10°N transport dust southward and upward due to orographic lifting. At their area of convergence, zonal wind transports the now elevated polluted dust eastward toward the Indian subcontinent. Subsidence and monsoon circulation reversal during boreal winter and fall limit vertical and horizontal aerosol transport from the India, particularly in the highly populated and always polluted Indo¬-Gangetic Plain. Polluted dust, polluted continental (non-elevated smoke), and smoke aerosols are confined near the surface and located over high population density areas and known biomass burning locations. Himalayan topography is an obvious barrier for the northward extent of aerosol. However, it also acts to create a meridional circulation limiting the southward extent of aerosol. Although transport pathways and the spatial structure of aerosol are well documented in the 2D sense, understanding the mechanisms controlling the vertical structure in concert with observation of the structure will be a valuable tool in reducing the uncertainty of aerosol effects in model simulations.

    Four years (2010-2014) of spectral aerosol optical depth (AOD) data from 4 Indian Space Research Organisation's ARFINET (Aerosol Radiative Forcing over India) stations (Shillong, Agartala, Imphal and Dibrugarh) in the North-Eastern Region (NER) of India (lying between 22-30°N and 89-98°E) are synthesized to evolve a regional aerosol representation, for the first time. Results show that the columnar AOD (an indicator of the column abundance of aerosols) is highest at Agartala (0.80 ± 0.24) in the west and lowest at Imphal (0.59 ± 0.23) in the east in the pre-monsoon season due to intense anthropogenic bio-mass burning in this region aided by long-range transport from the high aerosol laden regions of the Indo-Gangetic Plains (IGP), polluted Bangladesh and Bay of Bengal. In addition to local biogenic aerosols and pollutants emitted from brick kilns, oil/gas fields, household bio-fuel/fossil-fuel, vehicles, industries. Aerosol distribution and climatic impacts show a west to east gradient within the NER. For example, the climatological mean AODs are 0.67 ± 0.26, 0.52 ± 0.14, 0.40 ± 0.17 and 0.41 ± 0.23 respectively in Agartala, Shillong, Imphal and Dibrugarh which are geographically located from west to east within the NER. The average aerosol burden in NER ranks second highest with climatological mean AOD 0.49 ± 0.2 next to the Indo-Gangetic Plains where the climatological mean AOD is 0.64 ± 0.2 followed by the South and South-East Asia region. Elevated aerosol layers are observed over the eastern most stations Dibrugarh and Imphal, while at the western stations the concentrations are high near the surface. The climate implications of aerosols are evaluated in terms of aerosol radiative forcing (ARF) and consequent heating of the atmosphere in the region which follows AOD and exhibit high values in pre-monsoon season at all the locations except in Agartala. The highest ARF in the atmosphere occurs in the pre-monsoon season ranging from 48.6 Wm-2 in Agartala

    Background: Tattooing has become increasingly popular, particularly among young people. However, little is known about the tattoo practices in North-East India. Objectives: The primary objective of this study was to know the reasons and motivations of tattoo application and tattoo removal in individuals asking for tattoo removal. The secondary objective was to identify the demography, methods and safety of tattoo practices in these tattooed individuals. Materials and Methods: A hospital-based cross-sectional study was carried out in 212 consecutive individuals seeking tattoo removal. Chi-square and Fisher's exact tests were performed for intergroup comparisons. Results: There were 178 (84%) males and 34 (16%) females. The mean ± standard deviation (SD) age of individuals seeking tattoo removal was 21.8 ± 4 years. The mean ± SD age of doing tattoo was 15.8 ± 3 years. Most individuals possessed an amateur tattoo (94.3%), 4.2% a professional one and 1.4% had a combination. Sewing needle was the most common instrument used for making tattoos in 51.4%. The individuals made their tattoos in an unsterile manner in 49.1%. The most common reason for doing tattoo was for fashion in 87.7%. The participants wanted tattoo removal to qualify for jobs, especially in armed forces in 49.5% and due to regret in 21.7%. Black was the most preferred colour in 37.3% followed by green in 28.3%. The fabric ink was the choice of ink in maximum number of individuals, i.e. 93.9%. Limitations: It was a hospital-based study done only on individuals seeking tattoo removal. It needs caution to generalise the findings in population. In addition, there may be recall bias in the participants. Conclusion: The tattoo was done mostly below 18 years of age in a crude unsterile way. The individuals had poor risk perceptions about various infections and complications of tattooing. There is an urgent need to caution and educate the youngsters and school-going children about safe tattooing and

    Background: Globally, measles is the fifth killer disease among children under five years of age. Despite high immunization coverage in Himachal, outbreaks are occurring. Upon two outbreaks in a hilly district in North India, a case control study was conducted to identify factors contributing to outbreaks and to recommend remedial measures to prevent further outbreaks. Materials and Methods: Factors were reviewed under three heads: program related, health care providers, and beneficiaries related. Cold chain maintenance was determined and responses were compared between workers from study Shahpur and control Nagrota Bagwan blocks. All 69 mothers of age and sex matched children with measles were enrolled. A pre-designed pre-tested data collection instrument was used. For statistical analysis, the odds ratio (OR) and adjusted odds ratio with 95% confidence interval (C.I.) among women of children exposed and unexposed to selected characteristics were calculated. Results: Poor cold chain maintenance and gaps in knowledge of health workers supplemented with beneficiary-related issues precipitated outbreaks in case area. Univariate analysis yielded strong statistical significance to 17 variables. Important statistically significant variables are educational status; OR 27.63 (C.I. 9.46-85.16); occupation; OR 0.35 (C.I. 0.16-0.75); income; OR 5.49 (C.I. 2.36-13.00); mode of transport to health care facility; OR 8.74 (C.I. 2.90-28.23); spread of illness from one person to another; OR 5.60 (95% C.I. 1.40-25.97); first help for sick child OR 2.12 (C.I. 1.00-4.50), and place of visit after recovery; OR 3.92 (C.I. 1.80-8.63). Multiple logistic regression yielded significant association with educational status, drinking water sources, and time taken to reach the nearest health facility. Conclusion: Measles outbreaks were confirmed in high immunization coverage areas. We recommend 2nd dose opportunity for measles (MR) between 5 and 17 years; refresher trainings to workers; mobile

    Vegetative and reproductive phenology of Barringtonia acutangula, a floodplain tree species was studied at Chatla floodplain, Assam North East India with the aim to investigate vegetative and reproductive phenology under stressful environment of seasonal submergence and to assess the impact of environmental variables (temperature and precipitation) on tree phenophases. Quantitative assessment was made at 15 day interval for all the phenophases (leaf initiation, leaf-fall, flowering and fruiting) by tagging 40 (forty) trees over aperiod of two years (2012-14).To test seasonal influence on the phenology of Barringtonia acutangula different phenophases were correlated with environmental variables and statistical spearman's rank correlation coefficient was employed. Aridity index was computed that delineate influence of rainfall and temperature together on any phenophases. Leaf initiation showed positively significant correlation with temperature (r(s) = 0.601, p = < .05) during the year 2012-2013 whereas it was significantly correlated with rainfall (r(s) = 0.583, p = < .05) and aridity index (r(s) = 0.583, p = < .05) during the year 2013-2014. Leaf-fall was significant negatively correlated with temperature (r(s) = -0.623, p = < .05), rainfall (r(s) = -0.730, p = < .01) and aridity index (r(s) = -0.730, p = < .01) for both the studied years. Flowering was significantly influenced by temperature (r(s) = 0.639, p = < .05), rainfall (r(s) = 0.890, p = < .01) and aridity index (r(s) = 0.890, p = < .01) while in one month lag flowering was significantly correlated with rainfall (r(s) = 0.678, p = < .01) in 2012-13. Fruiting was also positively significant with temperature (r(s) = 0.795, P < .05), rainfall (r(s) = 0.835, P < .01) and aridity index (r(s) = 0.835, P < .01) for both the years. During one month lag period fruiting was positively correlated with temperature, rainfall and aridity index in both the years. Temperature, rainfall and aridity index were major

    Peste-des-petits- ruminants (PPR) is a highly contagious and devastating disease of goats and sheep. Although India is endemic for PPR, Tripura, a state in North East India has never been reported confirmed PPR outbreaks. Recently, an outbreak of PPR occurred in non-descript goats at the Sabroom town of Tripura state in North-East India in June, 2013. The causative agent, PPR virus (PPRV) was confirmed by sandwich ELISA, virus isolation and N gene based RT-PCR and sequencing. The sequence and phylogenetic analysis confirmed the involvement of lineage IV PPR virus in the outbreak. The outbreak viruses from Tripura state were clustered mainly with circulating viruses from Bangladesh, India, China, Pakistan, Tajikistan, Dubai and Kurdistan. However, the nucleotide sequence homology ranged from 99.2 to 99.6% with the PPR strains circulating in Bangladesh during 2011 and 2012 whereas 95.5-98% homology has been observed with the viruses from India and other countries. These findings suggest the transboundary circulation of PPR virus between India and Bangladesh border, which warrant immediate vaccination across the international border to create an immune belt.

    The population of Sikkim is a unique blend of multi-tribal and metropolitan culture. However, till date, no data regarding prevalence of sexually transmitted diseases (henceforth abbreviated as STDs) among this population is available and hence requires attention. Hence the objective is to determine the prevalence of STDs in Sikkim and to describe associated risk factors. A cross-sectional study involving 'Questionnaire-based anonymous feedback system' was followed to collect data from 2,000 individuals across the society. The four most common STDs, gonorrhea, syphilis, chlamydia and HIV, were considered for the study. Total 69 (3.6%) cases of STDs were found in 1,918 individuals was affected by at least one of the STDs, out of which 43 were males and 26 were females. Cases of gonorrhea, syphilis, chlamydiasis and HIV were 25, 22, 4 and 18 respectively. Out of total 69 cases of STDs, 20 individuals were also suffering from some kind of hepatitis. Addictions like alcoholism, smoking and drugs were also found in significant number, with 1,019 (>50%) individuals with at least one of these addictions. Relative risk analysis indicates that gender-wise females are more vulnerable to STDs than males. The number of partners, addictions, especially alcohol and drug abuse, also contribute to STD cases. STDs act as a significant risk factor in transmitting some of the types of hepatitis. In such cases, females are more vulnerable than males. The results suggest that new community health programs are essential for both, HIV and non-HIV STDs in Sikkim.

    A study on five naturally growing epiphytic orchids viz., Bulbophyllum affine Lindl., Coelogyne ochracea Lindl., Otochilus porrecta Lindl., Cirrhopetalum cornutum Lindl. and C. cornutum (var.) was carried out in the subtropical belt of Sikkim Himalaya. Stemflow leachates formed the main source of ammonium-N and nitrate-N for uptake by these orchids. Phosphorus concentration in the tissues of these orchids was high. Phosphate-P from stemflow does not seem to be a regular source of phosphorus for these orchids. Absorption/desorption results indicate that organic-N from stemflow leachates is not utilized by these orchids. PMID:21247907

    Manipur State, with a population of 2.29 million, is one of the seven North-Eastern Hill states in India, and is severely affected by groundwater arsenic contamination. Manipur has nine districts out of which four are in Manipur Valley where 59% of the people live on 10% of the land. These four districts are all arsenic contaminated. We analysed water samples from 628 tubewells for arsenic out of an expected total 2,014 tubewells in the Manipur Valley. Analyzed samples, 63.3%, contained >10 μg/l of arsenic, 23.2% between 10 and 50 μg/l, and 40% >50 μg/l. The percentages of contaminated wells above 10 and 50 μg/l are higher than in other arsenic affected states and countries of the Ganga-Meghna-Brahmaputra (GMB) Plain. Unlike on the GMB plains, in Manipur there is no systematic relation between arsenic concentration and the depth of tubewells. The source of arsenic in GMB Plain is sediments derived from the Himalaya and surrounding mountains. North-Eastern Hill states were formed at late phase of Himalaya orogeny, and so it will be found in the future that groundwater arsenic contamination in the valleys of other North-Eastern Hill states. Arsenic contaminated aquifers in Manipur Valley are mainly located within the Newer Alluvium. In Manipur, the high rainfall and abundant surface water resources can be exploited to avoid repeating the mass arsenic poisoning that has occurred on the GMB plains.

    Long-term impacts of drinking chlorinated water on the incidence of cancers and other adverse health outcomes were assessed in a population-based cross-sectional study. The study was conducted by comparing a group exposed to chlorinated drinking water for more than thirty years with control groups with less or no exposure to chlorine. A house-to-house survey was completed to gather information on residential history, age, education, income, source and extent of treatment of water and health characteristics. All residents below thirty years of age were excluded from the database used for analyses to ensure that the groups were comparable. Fourteen cancer cases were found in the long-term exposed groups of 1085 persons and 9 cancer cases in the two control populations of 725 persons. The odds ratio for cancers (OR) was 1.05 (95% CI = 0.43-2.65) and is not statistically significant. Reciprocal or inverse odds [corrected] ratios for gastrointestinal disorders, kidney problems and skin infections were statistically significant ranging from 2.06 (95% CI = 1.01-4.17) to 2.2 (95% CI = 1.45-3.33). These OR values indicate that there is no significant association between the incidence of cancer and exposure to chlorinated water while chlorinating drinking water significantly reduced the incidence of non-carcinogenic adverse health effects like gastrointestinal diseases, skin infections, and kidney diseases.

    Biomass burning causes intense perturbations to regional atmospheric chemistry and air quality and is a significant global source of reactive pollutants to the atmosphere (Andreae and Merlet, 2001). In November 2012, large areas in North India including New Delhi experienced several weeks of aggravated smog and poor air quality due to the impact of crop residue burning, which is a biannual post harvest activity that occurs during Oct-Nov and April-May every year in the agricultural belts of North western India. In-situ high temporal resolution (1 measurement every minute) measurements of a suite of volatile organic compounds measured using proton transfer reaction mass spectrometry (PTR-MS) such as acetonitrile (biomass burning tracer) and aromatic hydrocarbons were performed simultaneously with carbon monoxide, nitrogen oxides, ozone and aerosol mass concentrations (PM 2.5 and PM 10) at a suburban site (30.667°N, 76.729°E and 310 m asl), impacted by air masses that had passed over the burning fields less than 72 hours ago. By using data from the same season but before the post harvest crop residue burning activity had commenced, we were able to quantify enhancements in ambient levels of the measured species due to the crop residue burning activity. When air masses influenced by the fire emissions reached the measurement site, peak values of about 8 ppbV acetonitrile, 4 ppmV CO, 100 ppbV NOx , 30 ppbV toluene and 15 ppbV benzene were observed which represented a factor of 2-5 increase over their ambient levels in the non-fire influenced period. Emission ratios of aromatic hydrocarbons/CO also showed a marked increase. Non fire event (N.F. E.) influenced and fire event (F.E.) influenced air masses had the following emission ratio enhancements: benzene/CO (N.F.E = 3; F.E. = 5), toluene/CO (N.F.E = 4; F.E. = 8.7) and sum of C8 aromatics/CO (N.F.E = 4; F.E. = 7.3) and sum of C9 aromatics/CO (N.F.E = 2.6; F.E. = 3.4).

    The North West region of India is extremely important to understand the peopling of India, as it acted as a corridor to the foreign invaders from Eurasia and Central Asia. A series of these invasions along with multiple migrations led to intermixture of variable populations, strongly contributing to genetic variations. The present investigation was designed to explore the genetic diversities and affinities among the five major ethnic groups from North West India; Brahmin, Jat Sikh, Bania, Rajput and Gujjar. A total of 327 individuals of the abovementioned ethnic groups were analyzed for 4 Alu insertion marker loci (ACE, PV92, APO and D1) and a Single Nucleotide Polymorphism (SNP) rs2234693 in the intronic region of the ESR1 gene. Statistical analysis was performed to interpret the genetic structure and diversity of the population groups. Genotypes for ACE, APO, ESR1 and PV92 loci were found to be in Hardy-Weinberg equilibrium in all the ethnic groups, while significant departures were observed at the D1 locus in every investigated population after Bonferroni's correction. The average heterozygosity for all the loci in these ethnic groups was fairly substantial ranging from 0.3927 ± 0.1877 to 0.4333 ± 0.1416. Inbreeding coefficient indicated an overall 10% decrease in heterozygosity in these North West Indian populations. The gene differentiation among the populations was observed to be of the order of 0.013. Genetic distance estimates revealed that Gujjars were close to Banias and Jat Sikhs were close to Rajputs. Overall the study favored the recent division of the populations of North West India into largely endogamous groups. It was observed that the populations of North West India represent a more or less homogenous genetic entity, owing to their common ancestral history as well as geographical proximity.

    In this study, mineral magnetic properties and petroleum hydrocarbons were statistically analysed in four sediment cores (C1, A1, T1 and K1) from the north east coast of Tamilnadu, India to examine the feasibility of PHC concentrations assessment using magnetic susceptibility. The C1 and A1 cores reveal a clear horizon of increase in PHC above 35 and 50 cm respectively suggesting the excess anthropogenic loading occurred in the recent past. Magnetic properties which were enhanced in the upper part of the sediment cores were the result of ferrimagnetic minerals from anthropogenic sources. Factor analysis confirmed that the input of magnetic minerals and petroleum hydrocarbons in Chennai coastal sediments are derived from the same sources. The present study shows that instead of expensive and destructive PHC chemical methods, magnetic susceptibility is found to be a suitable, cheap and rapid method for detailed study of petroleum hydrocarbon contamination in marine sediments.

    Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL) involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient's case file. We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term. PMID:27597906

    During a survey of edible Crustacea for recovery of infective stages (metacercariae) of potential helminthozoonoses of trematode origin in north-east India, the crab species Barytelphusa lugubris mansoniana, collected from suspected foci of lungfluke infection in Meghalaya and Assam, was found to harbour metacercarial cysts that were different from the earlier reported infection, in which the lungfluke Paragonimus was confirmed to be implicated. Using morphological criteria, this metacercaria was identified as Microphallus indicus Mukherjee & Ghosh, 1967 of the trematode family Microphallidae. The present study extends the previous work by providing molecular characterization of this parasite using ribosomal internal transcribed spacer regions (rDNA ITS1 and ITS2) and the partial large ribosomal subunit DNA, lsr. These target regions were amplified by polymerase chain reaction (PCR) using trematode universal primers and sequenced. In BLAST analysis the query sequences were found close to members of Microphallidae and closest to the genus Microphallus.

    The accumulation of heavy metals such as lead (Pb), iron (Fe), zinc (Zn), cadmium (Cd), and chromium (Cr) was examined in crab (Scylla serrata) and shrimps (Penaeus semisulcatus, Penaeus indicus, and Penaeus monodon) collected from Pulicat lake that receives effluents from industries located in north Chennai, southeast coast of India. The results showed limited difference between crab and prawns as well as significant variations between the organs. Pb is the highly accumulated metal in both crab and shrimps, except P. monodon. The highest metal concentration was mostly found in the liver followed by other organs. The concentration of metals in edible parts (muscle) was within the permissible level and safe for consumption. However, the results of the study clearly indicate the biomagnification of metals in Pulicat lake.

    Background: The metabolic syndrome (MS) (syndrome X, insulin resistance syndrome) is a constellation of metabolic abnormalities and a complex predisease state that predicts future development of type 2 diabetes mellitus and cardiovascular disease. Menopausal transition and postmenopausal state are considered as a vulnerable period for developing MS, and this increased risk has been attributed to decreasing estrogen levels with an increasing risk of insulin resistance following menopause. Aims and Objectives: This study aimed to determine the prevalence of MS and its components in pre- and post-menopausal women from North India. Methodology: This is a cross-sectional study of 350 women in the age group of 45–55 years attending gynecology clinic in a tertiary center of North India. Details of sociodemographic data, menopausal history, reproductive, and medical profile were obtained. Then, waist circumference, body mass index (BMI), and blood pressure were recorded. A venous blood sample was collected for fasting blood glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. MS was defined according to the modified National Cholesterol Education Program Adult Treatment Panel III criteria. Results: The mean age was 49.09 ± 2.2 years in premenopausal and 49.54 ± 2.8 years in postmenopausal women. The prevalence of MS in the study group was 62.6%. Occurrence of MS was higher in older and obese women. Abnormal waist circumference was the most prevalent component (87%) of MS and in terms of odd ratio, correlation was highest for BMI followed by total cholesterol and waist-hip ratio. Conclusion: We should target obesity and deranged lipid profile by bringing out changes in lifestyle and dietary habits to decrease the higher prevalence of MS and the risk of cardiovascular diseases.

    Diversity of culturable bacterial populations within the Arsenic (As) contaminated groundwater of North Eastern state (Assam) of India is studied. From nine As contaminated samples 89 bacterial strains are isolated. 16S rRNA gene sequence analysis reveals predominance of Brevundimonas (35%) and Acidovorax (23%) along with Acinetobacter (10%), Pseudomonas (9%) and relatively less abundant (<5%) Undibacterium, Herbaspirillum, Rhodococcus, Staphylococcus, Bosea, Bacillus, Ralstonia, Caulobacter and Rhizobiales members. High As(III) resistance (MTC 10-50 mM) is observed for the isolates obtained from As(III) enrichment, particularly for 3 isolates of genus Brevundimonas (MTC 50 mM). In contrast, high resistance to As(V) (MTC as high as 550 mM) is present as a ubiquitous property, irrespective of isolates' enrichment condition. Bacterial genera affiliated to other groups showed relatively lower degree of As resistance [MTCs of 15-20 mM As(III) and 250-350 mM As(V)]. As(V) reductase activity is detected in strains with high As(V) as well as As(III) resistance. A strong correlation could be established among isolates capable of reductase activity and siderophore production as well as As(III) tolerance. A large number of isolates (nearly 50%) is capable of anaerobic respiration using alternate inorganic electron acceptors [As(V), Se(VI), Fe(III), [NO(3)(2), SO(4)(2), S(2)O(3)(2). Ability to utilize different carbon sources ranging from C2-C6 compounds along with some complex sugars is also observed. Particularly, a number of strains is found to possess ability to grow chemolithotrophically using As(III) as the electron donor. The study reports for the first time the identity and metabolic abilities of bacteria in As contaminated ground water of North East India, useful to elucidate the microbial role in influencing mobilization of As in the region.

    In this study, source parameters of the September 18, 2011 M w 6.9, Sikkim earthquake were determined using acceleration records. These parameters were then used to generate strong motion at a number of sites using the stochastic finite fault modeling technique to constrain the causative fault plane for this earthquake. The average values of corner frequency, seismic moment, stress drop and source radius were 0.12 Hz, 3.07 × 1026 dyne-cm, 115 bars and 9.68 km, respectively. The fault plane solution showed strike-slip movement with two nodal planes oriented along two prominent lineaments in the region, the NE-oriented Kanchendzonga and NW-oriented Tista lineaments. The ground motions were estimated considering both the nodal planes as causative faults and the results in terms of the peak ground accelerations (PGA) and Fourier spectra were then compared with the actual recordings. We found that the NW-SE striking nodal plane along the Tista lineament may have been the causative fault for the Sikkim earthquake, as PGA estimates are comparable with the observed recordings. We also observed that the Fourier spectrum is not a good parameter in deciding the causative fault plane.

    Background With the commitment of the national government to provide universal healthcare at cheap and affordable prices in India, public healthcare services are being strengthened in India. However, there is dearth of cost data for provision of health services through public system like primary & community health centres. In this study, we aim to bridge this gap in evidence by assessing the total annual and per capita cost of delivering the package of health services at PHC and CHC level. Secondly, we determined the per capita cost of delivering specific health services like cost per antenatal care visit, per institutional delivery, per outpatient consultation, per bed-day hospitalization etc. Methods We undertook economic costing of fourteen public health facilities (seven PHCs and CHCs each) in three North-Indian states viz., Haryana, Himachal Pradesh and Punjab. Bottom-up costing method was adopted for collection of data on all resources spent on delivery of health services in selected health facilities. Analysis was undertaken using a health system perspective. The joint costs like human resource, capital, and equipment were apportioned as per the time value spent on a particular service. Capital costs were discounted and annualized over the estimated life of the item. Mean annual costs and unit costs were estimated along with their 95% confidence intervals using bootstrap methodology. Results The overall annual cost of delivering services through public sector primary and community health facilities in three states of north India were INR 8.8 million (95% CI: 7,365,630–10,294,065) and INR 26.9 million (95% CI: 22,225,159.3–32,290,099.6), respectively. Human resources accounted for more than 50% of the overall costs at both the level of PHCs and CHCs. Per capita per year costs for provision of complete package of preventive, curative and promotive services at PHC and CHC were INR 170.8 (95% CI: 131.6–208.3) and INR162.1 (95% CI: 112–219

    A sediment core from Lonar Lake in central India covers the complete Holocene and was used to reconstruct the monsoon history of the core SW-monsoon region. We compare C/N ratios, stable carbon and nitrogen isotopes, grain size, as well as amino acid derived degradation proxies with climatically sensitive proxies of other records from South Asia and the North Atlantic region. The comparison reveals some more or less contemporaneous climate shifts. At Lonar Lake, a general long term climate transition from wet conditions during the early Holocene to drier conditions during the late Holocene, delineating the insolation curve, can be reconstructed. Several phases of shorter term climate alteration that superimpose the general climate trend correlate with cold phases in the North Atlantic region. The most pronounced climate deteriorations indicated by our data occurred between 6.2 - 5.2, 4.65 - 3.9, and 2.05 - 0.55 cal ka BP. The strong dry phase between 4.65 - 3.9 cal ka BP at Lonar Lake corroborates the hypothesis that severe climate deterioration contributed to the decline of the Indus Civilisation about 3.9 ka BP.

    Rotavirus G1 strains are the predominant cause of diarrhoea in children. Universally common rotavirus vaccines (Rotarix and RotaTeq) include G1 as the immunological component. India has recently introduced rotavirus vaccine in Universal Immunization Programme. Therefore, in the present study, VP7 gene of rotavirus G1 strains circulating in Himachal Pradesh, India is analysed to study their phylogenetic characteristics, and further comparative analysis was performed for assessment of their divergence from the vaccine strains. The rotavirus strains (JU-SOL-5, JU-SOL-58, JU-SOL-77, JU-SOL-173 and JU-SHI-14) analysed in the study were isolated from the faeces of diarrhoeic children during active surveillance for rotaviruses. The Himachal strains clustered together in G1-Lineage 1 in the phylogenetic analysis. All five isolates showed 96.4-98.8 % similarity with the other G1-Lineage 1 strains at amino acid level. However, none of them clustered in the pre-defined sublineages within lineage 1. Interestingly, all the strains were distantly related to the vaccine strains having 93.9-94.5 and 91.9-92.6 % similarities at amino acid level with Rotarix and RotaTeq strains, respectively. The comparative sequence and structural analysis of the Himachal strains with vaccine strains revealed differences in amino acids in epitope region of the protein especially at the antibody neutralization sites. The study highlights variations between the G1 strains from Himachal Pradesh, India and Rotarix and RotaTeq vaccine strains. These differences might have an impact on the neutralization efficiency of vaccine and subsequently on vaccine efficacy. This underscores further investigation to study intragenotype antigenic variability and also impact of viral evolution on vaccine effectiveness.

    Aim: To identify the suitable roofing pattern for dairy cattle in North East Zone of Tamil Nadu, India, based on micro climatic conditions. Materials and Methods: Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were selected. Temperature and temperature humidity index (THI) were recorded using the maximum-minimum thermometer and digital thermo-hygrometers. The study was conducted for 1 year covering four seasons namely South West monsoon (June-August), North East monsoon (September-November), cold season (December-February), and summer season (April-May). The data were statistically analyzed using statistical package SPSS 17. Results: Animal shelters with cement sheets recorded the highest temperature (26.71±1.13°C) and THI (77.23±1.76) at 8.00 am, whereas the lowest temperature (24.83±1.17°C) and THI (74.54±1.72) were recorded in the thatched shed. There was significant difference (p<0.01) in temperature and THI at 8.00 am during South West monsoon and North East monsoon seasons between the housing types. During cold and summer seasons, there was no significant difference (p≥0.05) in the environmental variables among various shelter systems. Conclusion: Thatched housing is found to be the suitable one with respect to the climatic variables, followed by tile roof and metal roof. The cement sheet roofed housing is found to be the most unsuitable one in the region for dairy cattle. PMID:28246440

    The issues of providing quality blood products and maintaining donor safety are primary aims of blood transfusion services. A comprehensive quality system should be in place to fulfill these aims, which can be attained through strict adherence to the established standard operating procedures (SOPs). The Drugs and Cosmetics Act of India, which controls the licensing of blood transfusion services, does not provide clear guidelines regarding plateletpheresis procedure. We, therefore, established our own SOP and operational flow chart for plateletpheresis that can be easily followed by other centers in India. A total of 100 plateletpheresis procedures performed using two cell separators (CS3000 Baxter Healthcare, Round Lake, IL; MCS3p, Haemonetics Corporation, Braintree, MA) were evaluated following our established SOP. The mean platelet yield in CS3000 was 2.9 +/- 0.84 x 10(11) and in MCS3p it was 2.88 +/- 0.75 x 10(11)per unit. However, only 4-7% of SDPs showed WBC levels <5 x 10(6) due to lack of appropriate methods to quantitate residual WBC counts. Six of 100 donors complained of hypocalcemic symptoms. The operational flow chart designed in this study was found to be simple and easy to adapt by blood transfusion services in this country.

    The aim of the study was to assess the prevalence of dental fluorosis, dental caries, and associated risk factors in the school children of district Fatehgarh Sahib, Punjab, India, using a cross-sectional study design. Oral health status of children aged between 8 and 15 years was assessed using World Health Organization (WHO) 2013 criteria. Dental fluorosis was assessed using Dean's index, and dental caries were recorded using decayed, missing, filled/decayed, extracted, filled (DMF/def) indices. Four hundred school children were examined, of which 207 were in the 8-11-year-old group and 193 were in the 12-15-year-old group. The overall prevalence of dental fluorosis was 4.1%, which might be linked to a high concentration of fluoride in drinking water at certain locations of rural Punjab. The prevalence of dental caries was 36.5% with a mean DMF score of 0.3 and def score of 0.6. Risk factors for dental caries include oral hygiene behavior and sugar consumption patterns. The study highlights the need to increase awareness about the oral health and hygiene among the school children in India.

    Background & objectives: Elevated blood pressure (BP) in the young predicts serious cardiovascular events in the adults. High prevalence of adult hypertension reported from Assam, North East (NE) India may be linked with elevated blood pressure in the childhood. The present study was an attempt to describe the distribution of BP and correlates of hypertension in children aged 5-14 yr. Methods: A total of 10,003 school children from 99 schools of Dibrugarh district, Assam, NE India, were surveyed by stratified random cluster method. Blood pressure, demographic and anthropometric information were recorded. Blood pressure was categorized in to normal, prehypertension, stage I and stage II hypertension. Results: Girls had significantly higher (104.2 ± 12.0 vs. 103.2 ± 11.6 mm Hg, P<0.001) mean systolic blood pressure (SBP) than boys. Both SBP and diastolic blood pressure (DBP) revealed significant correlation with age, height, weight and BMI in overall and in gender specific analysis. Hypertension was found in 7.6 per cent school children (Boys: 7.3%, Girls: 7.8%). In multivariable analysis older age (OR 3.3, 95% CI: 2.82-3.91), children from tea garden community (OR 1.3, 95% CI: 1.08-1.55) and other community (OR 1.4, 95% CI: 1.18-1.73) and overweight (OR 1.5, 95% CI: 1.1-2.1) were independently associated with hypertension. Interpretation & conclusions: Mean blood pressure in the young school children of 5-14 yr was high. A programme comprising screening, early detection and health promotion through school health programmes may help prevent future complications of hypertension. PMID:26458345

    Background & objectives: There is a paucity of data from India on response to treatment of tuberculosis (TB) in patients with human immunodeficiency virus (HIV)-TB co-infection. This study was done to assess the frequency and pattern of TB, outcome of anti-tuberculosis treatment, and the factors related to poor outcome of TB treatment in adult patients with HIV infection. Methods: Retrospective review of case records of HIV-TB co-infected patients attending the antiretroviral therapy (ART) clinic in a tertiary care centre in north India was done. Results: Of the 1754 patients included in the study, 583 (33.2%) were diagnosed with active TB and 466 (79.9%) of them had CD4 count less than 200/μl at diagnosis. Extrapulmonary TB was diagnosed in 372 (63.8%) patients [76 (20.4%) had disseminated TB], and pulmonary TB in 211 (36.2%) patients. Favourable outcome (cure and completed treatment) was observed in 332 (77%) patients. Unfavourable outcome included default (8.1%), treatment failure (1.6%), and death (13.2%). At 1-year post-treatment follow up, 12 (3.6%) patients had disease relapse. CD4 count of less than 200/μl at diagnosis [OR-2.32, CI (1.06-5.09)], and retreatment cases [OR-2.91, CI (1.22-6.89)] were independent predictors of unfavourable outcome. Interpretation & conclusions: There is an urgent need to strengthen the information, education, communication activities and expand the ART services to meet the requirement of early testing and treatment initiation in patients co-infected with HIV-TB. The findings highlight the need for performing drug susceptibility testing (DST) for patients starting retreatment regimen to improve treatment outcome. PMID:24604050

    Background: Rural areas pose challenges for motivating villagers to donate blood. We organized a blood donation camp in a rural setting by engaging multiple stakeholders. We examined the factors that influenced blood donation. Methods: Local level stakeholders were involved in planning of the camp. Mobilization of donors was attempted through intensive awareness generation activities utilizing multiple channels. A list of willing blood donors was prepared. Results: Out of 152 willing donors, 88 reported to donation camp, and after screening, 67 donated the blood. Most of the willing donors were males (89.8%), and the mean standard deviation age was 31.9 (9.4) years. Deferral rate was 23.8%. Involvement of local stakeholders can result in creating a pool of donors in rural area which can mitigate the existing gap between demand and supply of blood in India. PMID:28217590

    Since a very long time, a significant number of patients have been seeking treatment at Complementary and Alternative Medicine health facilities, but the disease burden at these facilities has never been assessed and documented. Present cross-sectional study was carried out at Ayurvedic tertiary care hospital to document and to assess the rationale of disease reporting at Ayurvedic institutions of the northern state of India from January 2011 to October 2011. Almost half of the patients’ morbidities were not classified at all into any of the disease categories. The common reported morbidities at study hospital were: Respiratory (10.5%), neuromuscular (9.5%), digestive (9.2%) and circulatory (9.1%) disorders. As the majority of diseases were unclassified, so mainstreaming of the effective disease surveillance would be required to understand the morbidity pattern and successful treatment practices at health facilities.

    Dermatoglyphic print comparisons can be utilized to establish personal identification in forensic cases. The northern part of the state of West Bengal, India, is the home to many ethnic populations. Two such populations are the Rajbanshi and the Mech. Palm prints were collected from 192 adult Rajbanshi (105 men and 87 women) and 100 adult Mech (50 men and 50 women) individuals for print comparison using the standard ink and roll print method. The dermatoglyphic variables studied were mainline formulae, termination of mainline, positional variation of axial triradii, and true pattern of hypothenar and thenar configuration area. There were differences between the Rajbanshi and Mech individuals with respect to these dermatoglyphic variables. The uses of these variables appear to be limited only to ethnic identification, not personal identification. The present investigation further highlights the racial affinity, sex, and bilateral differences among Rajbanshi individuals using dermatoglyphic palmar variables.

    Helminthozoonoses are being considered as a research priority in India and many other tropical and subtropical countries. Taenia solium and Trichinella spiralis are emerging public health and food safety issues in the country and the developing world. The asymptomatic Ta. solium carriers act as important risk for neurocysticercosis, leading to adult onset epilepsy in the country. Human toxocariasis is another common zoonosis which occurs due to larvae of Toxocara canis or T. cati. The current study was planned to obtain baseline seropositivity data for Ta. solium, To. canis and Tr. spiralis antibodies among selected populations in Punjab province of northern India. In the present study, 122 human subjects belonging to selected occupations viz. farmers and veterinary practitioners were screened using the RIDASCREEN(®) Ta. solium IgG, RIDASCREEN(®) Toxocara IgG and RIDASCREEN(®) Trichinella IgG enzyme immunoassays for the qualitative determination of IgG antibodies against Ta. solium, Tr. spiralis and To. canis, respectively in human serum. The seropositivity of To. canis, Tr. spiralis and Ta. solium infections were found to be 22.13, 5.73 and 11.47 %, respectively in human serum samples. The relative risk of being infected for To. canis, Tr. spiralis and Ta. solium infections was found to be 1.91 (95 % CI 0.786-4.669), 2.61 (95 % CI 0.3258-20.94) and 1.596 (95 % CI 0.427-5.3893) times high respectively in farmers when compared to veterinary practitioners. The present study indicates that exposure to To. canis and Ta. solium is not uncommon among farmers and veterinary practitioners in this part of the country. These results provided evidence of Tr. spiralis among selected human populations in the country and demand more research related to trichinellosis in their respective animal and human hosts.

  14. Treatment-seeking for febrile illness in north-east India: an epidemiological study in the malaria endemic zone

    PubMed Central

    2009-01-01

    Background This paper studies the determinants of utilization of health care services, especially for treatment of febrile illness in the malaria endemic area of north-east India. Methods An area served by two districts of Upper Assam representing people living in malaria endemic area was selected for household survey. A sample of 1,989 households, in which at least one member of household suffered from febrile illness during last three months and received treatment from health service providers, were selected randomly and interviewed by using the structured questionnaire. The individual characteristics of patients including social indicators, area of residence and distance of health service centers has been used to discriminate or group the patients with respect to their initial and final choice of service providers. Results Of 1,989 surveyed households, initial choice of treatment-seeking for febrile illness was self-medication (17.8%), traditional healer (Vaidya)(39.2%), government (29.3%) and private (13.7%) health services. Multinomial logistic regression (MLR) analysis exhibits the influence of occupation, area of residence and ethnicity on choice of health service providers. The traditional system of medicine was commonly used by the people living in remote areas compared with towns. As all the febrile cases finally received treatment either from government or private health service providers, the odds (Multivariate Rate Ratio) was almost three-times higher in favour of government services for lower households income people compared to private. Conclusion The study indicates the popular use of self-medication and traditional system especially in remote areas, which may be the main cause of delay in diagnosis of malaria. The malaria training given to the paramedical staff to assist the health care delivery needs to be intensified and expanded in north-east India. The people who are economically poor and living in remote areas mainly visit the government

    Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and hystricid rodents. We examined the role played by these rodents in determining the seed fates of tropical evergreen tree species in a forest site in north-east India. We selected ten tree species (3 mammal-dispersed and 7 bird-dispersed) that varied in seed size and followed the fates of 10,777 tagged seeds. We used camera traps to determine the identity of rodent visitors, visitation rates and their seed-handling behavior. Seeds of all tree species were handled by at least one rodent taxon. Overall rates of seed removal (44.5%) were much higher than direct on-site seed predation (9.9%), but seed-handling behavior differed between the terrestrial rodent groups: two species of murid rodents removed and cached seeds, and two species of porcupines were on-site seed predators. In addition, a true cricket, Brachytrupes sp., cached seeds of three species underground. We found 309 caches formed by the rodents and the cricket; most were single-seeded (79%) and seeds were moved up to 19 m. Over 40% of seeds were re-cached from primary cache locations, while about 12% germinated in the primary caches. Seed removal rates varied widely amongst tree species, from 3% in Beilschmiedia assamica to 97% in Actinodaphne obovata. Seed predation was observed in nine species. Chisocheton cumingianus (57%) and Prunus ceylanica (25%) had moderate levels of seed predation while the remaining species had less than 10% seed predation. We hypothesized that seed traits that provide information on resource quantity would influence rodent choice of a seed, while traits that determine resource accessibility would influence whether seeds are removed or eaten. Removal rates significantly decreased (p < 0.001) while predation rates increased (p = 0

    The aim of this study is to report the regional distribution of Cryptococcus. gattii and Cryptococcus. neoformans in decayed wood inside trunk hollows of Syzygium cumini trees (Java plum, Indian black berry) investigated in Amritsar (Panjab), Meerut Cantt. and Bulandshahr (Uttar Pradesh) and Delhi, in north-western India. Two hundred and seventeen wood samples collected from 74 S. cumini trees were investigated. This includes 7 known positive S. cumini trees in Delhi subjected to a mycological surveillance for perennial colonization by C. gattii and C. neoformans. Cryptococcus gattii showed the highest prevalence (89%) in S. cumini trees in Delhi, followed by 27%, 12.5% and 9% prevalence in Bulandshahr, Amritsar City and Meerut Cantt., respectively. In contrast, C. neoformans had the highest prevalence (54%) in Amritsar, followed by 44% in Delhi, 9% in Bulandshahr and 0% in Meerut Cantt. Furthermore, 44% of the S. cumini trees in Delhi, 9% in Bulandshahr and 8% in Amritsar were concomitantly colonized by both C. gattii and C. neoformans. A mycological surveillance over 4.8-5.2 years of 7 selected S. cumini trees in Delhi revealed perennial colonization by both the Cryptococcus species. In addition, air samples taken close to the decayed trunk hollows of 4 of the perennially colonized S. cumini trees contained strains of the C. neoformans species complex. Of a random sample of 48 isolates serotyped, 26 (54%) were C. neoformans, serotype A, and 22 (46%) C. gattii, serotype B. Determination of mating type alleles was done in 44 of the isolates, comprising 31 of C. neoformans, serotype A and 13 of C.gattii, serotype B. All of them proved to be mating type alpha (MATalpha). The data on high prevalence, fungal population density, perennial colonization and aerial isolations indicate that decayed wood in trunk hollows of S. cumini trees is to-date the main well documented primary environmental niche of C. gattii and C. neoformans in north-western India.

    In the Hazara arc region of northern Pakistan, some of the active basements structures buried below a thick, detached sedimentary layer are inferred from the distribution of lineaments and the drainage patterns, as viewed in Landsat satellite imagery and from river profiles. A prominent set of NW-trending lineaments seen on satellite imagery, coincides approximately with the southwest or updip side of the Indus—Kohistan seismic zone (IKSZ) —the most active basement structure of the region, even though this structure is buried beneath and decoupled from a 12 km thick sedimentary layer. The IKSZ has been interpreted as an extension of the Himalayan Basement Thrust, and is also associated with a prominent topographic "step". Knickpoints on major rivers in the region lie on or north of the IKSZ. All Indus River tributaries, examined north of the IKSZ, show prominent knickpoints, while two tributaries draining south of the IKSZ have no knickpoints. These results suggest ongoing uplift above and north of the IKSZ, and are consistent with the tectonic model obtained from the seismic data. Another prominent lineament set is detected along the north—south section of the Indus River. This set is probably related to the Indus River horst—anticline and associated reentrant. One of the two highest lineament concentrations occurs at the intersection between the NW-trending IKSZ lineament and the N-trending Indus River lineament. The other is along the west bank of the Indus Valley, 25 km north of Tarbela Dam. A topographic ridge (Swabi—Nowshera ridge) appears to be forming along the west side of the Indus River, in the Peshawar Basin. The rising ridge is ponding the Kabul River upstream of Nowshera, where the drainage is braided.

    This study describes biochemical and biological properties of Naja kaouthia (Indian monocled cobra) venom of North-East India. The LD50 of the crude venom was found to be 0.148mg/kg and neurotoxicitic symptoms like paralysis of lower limbs and heavy difficulty in breathing at sub-lethal dose in mice was observed. The venom exhibited PLA2, indirect hemolytic and myotoxic activities but showed weak proteolytic and low direct hemolytic activities. It did not exhibit any hemorrhage when injected intradermally to mice. Anticoagulant activity was prominent when recalcification, prothrombin and activated partial thrombinplastin time were tested on platelet poor plasma. Rotem analysis of whole citrated blood in presence of venom showed delay in coagulation time and clot formation time. Fibrinogen of whole citrated blood was depleted by venom when analyzed in Sonoclot. Crude venom at 10µg and after 16hr of incubation was found to degrade α chain of fibrinogen. Neutralization study showed that Indian polyvalent antivenom could neutralize some of the biochemical and biological activities as well as its fibrinogenolytic activity. PMID:24349704

    Background Proper management of Biomedical waste (BMW) generated in a healthcare facility is one of the most important functions of a healthcare worker (HCW) as its improper management not only poses risk to human beings and environment, but may also invite legal action against HCW as well as hospital administration. This study was carried out to evaluate quality of BMW management in 1100-bedded hospital attached to a tertiary care public institute in North India. Methods A checklist, including 29 parameters related to various functions to be carried out at source of generation by a HCW for BMW management was prepared by researcher and used after validation to record observations in all the 70 areas of hospital. A total of 6 visits were made to each area and mean percentage score was calculated for each area and each category of waste management. Results It was found that summated mean percentage score of ‘Treatment Room of Wards’, which were used exclusively by resident doctors, was significantly lower than Operation Theatres (p value: 0.033) and ‘Central Waste Collection Points of Wards’ (p value: 0.018) for the function of ‘mutilation of recyclable waste’ and it was significantly lower than all other areas (p value: 0.006 to 0.017) for the function of ‘disinfection of waste’. Conclusion It is concluded that more emphasis needs to be laid on ‘mutilation of recyclable waste’ and disinfection of waste’ by HCWs especially resident doctors. PMID:24742274

    The etiological spectrum of viral hepatitis and the prevalence of serological markers of hepatitis A and B virus infection in healthy persons in north India were studied. Hepatitis A virus was found to be the most common cause of acute hepatitis in children (67%). It was a less frequent cause of this disease in adults (14%). Hepatitis A virus was only rarely the cause of acute (12%) and subacute (4%) liver failure. It was recorded as the etiological agent in an epidemic among schoolchildren. Exposure to hepatitis A virus occurs in early childhood, and by the age of 10 years, 90% of healthy persons have serological evidence of hepatitis A virus infection. Hepatitis non-A non-B virus was the cause of acute hepatitis in 44% of adults and 24% of children with this disease. This virus was also the most important etiological agent in acute liver failure (55%) and subacute hepatic failure (51%). It was the cause of all the hepatitis epidemics in the general population. Only 9% of hepatitis cases in children were due to hepatitis B virus whereas 42% of cases in adults were attributable to this virus. Hepatitis B virus was the causative agent in 33% of cases of acute hepatic failure and 45% of cases of subacute hepatic failure. The carrier rate for hepatitis B virus was 5% and antibody to hepatitis B surface antigen was found in up to 38% of specific population groups. PMID:6424958

    Context: Emergency contraception (EC) is use of drug or device to prevent pregnancy after unprotected sexual intercourse. Unlike other regular methods of contraception which are taken prior to the sexual act, EC is used after the unprotected sex. Aim: To assess the knowledge and attitude toward use of emergency contraceptives among medical students. Setting and Design: A cross-sectional questionnaire based study was conducted among all the medical students in the Government Medical College in North-West India. Subjects and Methods: A questionnaire seeking information on knowledge and attitude of undergraduate medical students was administered over a period of 4 weeks in the month of February and March 2014. Statistical Analysis: The data were entered in MS excel and expressed using percentages. Chi-square test was used as a test of statistical significance. Results: About 61.6% (247/401) of the participants were aware about the timing of use of EC. Audio visual media (76.6%; 307/401) was the most common source of information for of these medical students. Conclusions: The lack of appropriate in-depth knowledge of EC among future health care professional should alarm the medical teaching system as EC is the only method that can be used to prevent pregnancy after unprotected sex or contraceptive accident.

    Introduction: Early diagnosis and management of depression is important for better therapeutic outcome. Strategies for distinguishing between unipolar and bipolar depression are yet to be defined, resulting improper management. This study aims at comparing the socio-demographic and other variables between patients with unipolar and bipolar depression, along with assessment of severity of depression. Materials and Methods: This cross sectional study was conducted in a tertiary care psychiatry hospital in North-East India. The study included total of 330 subjects selected through purposive sampling technique from outpatient department after obtaining due informed consent. Mini-International Neuropsychiatric Interview (M.I.N.I.) version 6.0 and Beck Depression Inventory (BDI) were applied. Statistical Package for Social Sciences (SPSS) version 16.0 was applied for analysis. Results: Bipolar group had onset of illness at significantly younger age with more chronicity (32.85 ± 11.084). Mean BDI score was significantly higher in the unipolar depressive group. Conclusion: Careful approach in eliciting symptom severity and associated socio demographic profiles in depressed patients may be helpful in early diagnosis of bipolar depression. PMID:28250558

    Outbreaks of enteric fever are a major health concern not only due to significant human morbidity and mortality but also fear of spread of multidrug resistant strains. We report an outbreak of enteric fever caused by Salmonella enterica serotype Typhi in a suburban area, in city Chandigarh of North India. Twenty-seven strains of S. typhi were isolated from blood cultures over a period of two weeks with 18 of these 27 patients residing in the same area. Maximum cases were in the age group 5-14 years (10 patients, 55.5%) while 4 (22.2%) cases were children under 5 years. All the strains showed similar resistogram being resistant to ampicillin and nalidixic acid, intermediate to ciprofloxacin and sensitive to chloramphenicol, ceftriaxone, cefotaxime, cotrimoxazole and azithromycin on disc diffusion testing. Minimum inhibitory concentration of ciprofloxacin was determined by agar dilution method and was found to be raised (≥ 2 μ g/mL). This nalidixic acid resistant S. typhi outbreak report warrants the necessity of implementing stringent sanitation practices in public health interest.

    There is a lack of information on the disease burden due to Taenia solium taeniasis and its associated risk factors in pig farming communities throughout the world. The present study was conducted in a rural pig farming community of north India to estimate the prevalence of T. solium taeniasis and associated factors. Demographic, clinical and epidemiological data were collected from 1181 subjects in 210 households in 30 villages. Stool specimens from 924 subjects were examined for eggs of Taenia and other parasites. Identification of T. solium was confirmed by morphological features of segments and species-specific DNA detection from segments and stool. The prevalence of T. solium taeniasis was 18.6% (172/924); factors associated with taeniasis on multivariate analysis were age above 15 years, history of passage of Taenia segments in stool, undercooked pork consumption and poor hand hygiene (hand-washing with clay/water after defecation). Seventy-eight subjects (6.6%) with epilepsy were identified. The study showed alarmingly high rates of epilepsy and T. solium taeniasis in the study community; it highlights the need for large-scale imaging-based surveys to identify the factors associated with epilepsy including neurocysticercosis. Health education, mass anthelminthic therapy and other preventive measures are required to control the menace of the disease.

    Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is characterized by acute- or subacute-onset encephalopathy with extrapyramidal, psychiatric, and epileptic manifestations. Diagnosis is confirmed by positive antibodies to NMDA receptor in cerebrospinal fluid and serum. Eleven pediatric cases presented over a 2-year period at a tertiary care teaching hospital in North India. The average age at presentation was 9 years (range: 2.5 to 18 years, median: 10 years) with a slight female predominance (1.2:1). The common modes of presentation were progressive extrapyramidal syndrome with global neuroregression in 45% (5 of 11), epileptiform encephalopathy in 27% (3 of 11), and an overlap between the 2 in 27% (3 of 11). Fifty-eight percent showed significant response to steroids and intravenous immunoglobulin. This entity should be considered in an acute- or subacute-onset encephalopathy if common infectious etiologies are ruled out and there are specific clinical pointers. Early diagnosis and treatment significantly improves the outcome.

    The present study analyses the potential role of MTHFR gene polymorphism, folate supplementation and dietary pattern among the mothers of NTD neonates and controls in heterogeneous populations of North India, with the special focus on their ethnic labels. Results indicated significant increased risk for neural tube defects with respect to low folic acid supplementation and vegetarian diet in univariate and multivariate analyses. There was no significant difference in the genotypic or allelic distribution of MTHFR C677T polymorphism, however, high frequency of CT genotype, as observed, among controls suggests heterozygous advantage probably due to supplementary folate. Among the two communities, Muslim NTD mothers had higher TT genotype showing increased risk for neural tube defects (adjusted OR: 12.9; 95% CI: 1.21-136.8) and lower folic acid supplementation (adjusted OR: 3.5; 95% CI: 1.18-10.22). Whereas, marginal increased risk for NTDs with vegetarian diet was observed among Hindus. Cultural and ethnic variation in the risk factors for neural tube defects is highlighted in the study.

    This study aimed to understand how adolescents with disabilities can assume greater control over their rehabilitation and participation within a community-based rehabilitation programme in the urban slums of North India. A critical ethnographical approach using multiple qualitative and participatory data collection methods was adopted. Fieldwork was conducted from January to May 2005 and October 2006 to March 2007 with 21 adolescents with and 11 adolescents without disabilities (aged 12 to 18 years), and 10 community-based rehabilitation staff members. A conceptual framework called the 'Adolescent Group Empowerment Pyramid' was developed. Four themes informed the framework: group participation, group demonstration, group recognition and the socio-cultural environment's interaction with disability. Group empowerment, achieved through group-centred occupations, encourages adolescents to work together to address their rehabilitation challenges and agendas. Three external support factors and 10 areas for nurturing the group empowerment process also emerged. A limitation of this study is the lack of data on how the familial and local political and economic environment impact adolescents' ability to make decisions about their rehabilitation. Further research might explore group occupations and occupational recognition, and what this means for social change and the personal and collective growth of adolescents in underserviced communities.

    The north eastern part of Anantapur district is in the state of Andhra Pradesh, India, is significant as it is covered by varied geological formations and has different land use and irrigation practices. Though ground water is the major drinking water source, deterioration in its quality is going unchecked. In such agro-economy based rural areas, the nitrate contamination is rampant and much attention has not been drawn towards this anthropogenic pollution. In the study area ground water samples from different hydrogeological set-up have been collected during the pre and post monsoon seasons and analysed for the major ions such as Ca, Mg, Na, K, CO(3), HCO(3), Cl, SO(4), NO(3) and F. The study revealed that 65% of the samples were found to be unsuitable for drinking purposes in the pre monsoon season and 45% in the post monsoon due to excess nitrate (>45 mg/l) content in the ground water. Among the different seasons and environs, nitrate was in highest concentration in the granitic terrain and canal command areas during pre monsoon season. The nitrate was found to decrease with depth in all the hydrogeological set-ups in both the seasons. Intense agriculture practices, improper sewerage and organic waste disposal methods were observed to contribute nitrate to the shallow and moderately deep aquifers.

    The continuous soil gas radon monitoring is carried out at Palampur and the daily monitoring of radon concentration in water is carried out at Dharamshala region of Kangra valley of North West Himalayas, India, a seismic zone V, to study the correlation of radon anomalies in relation to seismic activities. In this study, radon monitoring in soil was carried out by using barasol probe manufactured by Algade France, whereas the radon content in water was recorded using RAD 7 radon monitoring system of Durridge Company USA. The effect of meteorological parameters viz. temperature, pressure, wind velocity, rainfall, and humidity on radon emission has been studied. The seasonal average value and standard deviation of radon in soil and water is calculated to find the radon anomaly to minimize the effect of meteorological parameters on radon emission. The radon anomalies observed in the region have been correlated with the seismic events of M>or=2 reported by Wadia Institute of Himalayas Geology Dehradoon and Indian Meteorological Department, New Delhi in NW Himalayas within 250km distance from the monitoring stations.

    The family Pentatomidae is one of the largest families of the sub-order Heteroptera, comprising 4722 species belonging to 896 genera. In the present paper, we analysed a partial ∼600 bp COI sequence of 14 species of family Pentatomidae, collected from northern part of India. For seven species viz., Tolumnia antennata Distant, 1902, Cahara jugatoria (Lethierry, 1891), Bagrada hilaris (Burmeister, 1835), Plautia viridicollis (Westwood, 1837), Priassus exemptus (Walker, 1868), Dalpada neoclavata (Rider, 1998) and Dalpada affinis (Dallas, 1851), this is the first ever molecular study which has generated distinct barcodes for each. The COI sequences of these seven species have been added to the existing database at GenBank NCBI which can be used for their identification. The database analysis shows mean K2P divergence of 2.5% at intraspecific level, 11.9% at interspecific level and 16.37% at intergeneric level, thereby indicating a hierarchical increase in K2P mean divergence across different taxonomic levels.

    Background: Mucocutaneous diseases are among the first-recognized clinical manifestations of acquired immune deficiency syndrome. They function as visual markers in assessing the progression of human immunodeficiency virus (HIV) infection. Given the relative ease of examination of skin, its evaluation remains an important tool in the diagnosis of HIV infection. Objective: To determine the pattern of mucocutaneous manifestations in HIV-positive patients and to correlate their presence with CD4 counts. Materials and Methods: This cross-sectional study included 352 HIV-infected patients seen at PGIMER, Chandigarh, India, over a period of 1 year. The patients were screened for mucocutaneous disorders by an experienced dermatologist. The patients were classified into different stages according to the World Health Organization clinical and immunological staging system. Results: The most prevalent infection was candidiasis, seen in 57 patients (16.2%). Prevalence of candidiasis, dermatophytosis, herpes simplex, herpes zoster, molluscum contagiosum (MC), seborrheic dermatitis, adverse drug reaction, nail pigmentation, xerosis and diffuse hair loss differed statistically according to the clinical stages of HIV infection. There was a statistically significant association between immunological stages of HIV infection and dermatophytosis. Conclusion: Results of our study suggest that mucocutaneous findings occur throughout the course of HIV infection. Dermatoses like MC and dermatophytosis show an inverse relation with CD4 cell count, and these dermatoses can be used as a proxy indicator of advanced immunosuppression to start highly active anti-retroviral therapy in the absence of facilities to carry out CD4 cell count.

    Psychiatric disorders in India are often attributed to influence of supernatural phenomena, and many patients are subjected to various kinds of 'magico-religious' treatments. We studied 40 cases of schizophrenia and ascertained magico-religious beliefs held by their key relatives. The effects of such magico-religious beliefs on psychopathology and treatment-seeking behaviour were explored. The sample were schizophrenia patients diagnosed according to ICD-10 of the World Health Organisation. Psychopathology was assessed on the 9th version of the Present State Examination (PSE-9). Supernatural Attitude Questionnaire was administered to the key relatives of the patients to ascertain their beliefs about various supernatural phenomena and magico-religious treatments. It was observed that the majority of the patients had undergone magico-religious treatment (n = 23). Nearly 74% of the patients who had symptoms coloured by cultural influences such as delusional explanation in terms of paranormal phenomena had undergone magico-religious treatment. It was also seen that though many relatives denied personal conviction in such magico-religious beliefs, yet they sought some kind of magico-religious treatment for the patients. The prevalence of culturally influenced delusions as defined by the PSE-9 was very low. Belief in supernatural influences is common in patients' relatives from urban background and with adequate education, and treatment based upon such beliefs is sought to a considerable extent in such cases. Local and community belief in such phenomena appeared to be a factor in influencing the decision to seek magico-religious treatment.

    Congenital cataract has the potential for inhibiting early visual development. Intrauterine infections with Rubella virus, Herpes simplex virus (HSV) and Toxoplasma gondii plays an important role in the development of congenital cataract. The study included 120 children under the age of 6 years presenting with congenital cataract and diagnosed using serology and polymerase chain reaction (PCR). The IgM positivity for rubella, HSV, T. gondii was found to be 5.8%, 1.6% and 8.3% respectively. The overall PCR positivity was found to be 40(33.3%), 25 (20.8%) and 39 (32.5%) for rubella, HSV and T. gondii with mean copy number of 1599 copies/μL; 1716 copies/μL and 1503 copies/μL respectively. Infective etiology significantly contributes to the causation of congenital cataract particularly for rubella virus which is a potentially eradicable disease. This study provides an epidemiological data for rubella, HSV and T. gondii in children with congenital cataract and highlights the need to introduce rubella vaccine in the National Immunization Programme of India.

    The current study area is coastal zone of Visakhapatnam, district of Andhra Pradesh along the coast of India. This area is mostly vulnerable to many disasters such as storms, cyclone, flood, tsunami and erosion. This area is considered as cyclone prone area because of frequently occurrence of the cyclones in this area. Recently the two tropical cyclones that formed in the Bay of Bengal are Hudhud (October 13, 2014) and Phylin (October 11, 2013), has caused devastating impacts on the eastern coast and shows that the country has lack of preparedness to cyclone, storm surge and related natural hazards. The multi-hazard vulnerability maps prepared here are a blended and combined overlay of multiple hazards those affecting the coastal zone. The present study aims to develop a methodology for coastal multi-hazard vulnerability assessment. This study carried out using parameters like probability of coastal slope, tsunami arrival height, future sea level rise, coastal erosion and tidal range. The multi-hazard vulnerability maps prepared by overlaying of multi hazards those affecting the coastal zone. Multi-hazard vulnerability maps further reproduced as risk maps with the land use information. The decision making tools presented here can provide a useful information during the disaster for the evacuation process and to evolve a management strategy.

    Correct estimation of soil loss at catchment level helps the land and water resources planners to identify priority areas for soil conservation measures. Soil erosion is one of the major hazards affected by the climate change, particularly the increasing intensity of rainfall resulted in increasing erosion, apart from other factors like landuse change. Changes in climate have an adverse effect with increasing rainfall. It has caused increasing concern for modeling the future rainfall and projecting future soil erosion. In the present study, future rainfall has been generated with the downscaling of GCM (Global Circulation Model) data of Mandakini river basin, a hilly catchment in the state of Uttarakhand, India, to obtain future impact on soil erosion within the basin. The USLE is an erosion prediction model designed to predict the long-term average annual soil loss from specific field slopes in specified landuse and management systems (i.e., crops, rangeland, and recreational areas) using remote sensing and GIS technologies. Future soil erosion has shown increasing trend due to increasing rainfall which has been generated from the statistical-based downscaling method.

    There is little documentation of the potential catastrophic effects of injuries on families due to out of pocket (OOP) expenditure for medical care. Patients who were admitted for at least one night in a tertiary care hospital of Chandigarh city due to injury were recruited and were followed-up at 1, 2 and 12 months after discharge to collect information on OOP expenditure. Out of the total 227 patients, 60% (137/227) had sustained road traffic injuries (RTI). The average OOP expenditure per hospitalisation and up to 12 months post discharge was USD 388 (95% CI: 332–441) and USD 1046 (95% CI: 871–1221) respectively. Mean OOP expenditure for RTI and non-RTI cases during hospitalisation was USD 400 (95% CI: 344–456) and USD 369 (95% CI: 313–425) respectively. The prevalence of catastrophic expenditure was 30%, and was significantly higher among those belonging to the lowest income quartile (OR-26.50, 95% CI: 6.70–105.07, p-value: <0.01) and with an inpatient stay greater than 7 days (OR-10.60, 95% CI: 4.21–26.64, p-value: <0.01). High OOP expenditure for treatment of injury puts a significant economic burden on families. Measures aimed at increasing public health spending for prevention of injury and providing financial risk protection are urgently required in India. PMID:27384572

    The behaviour of so called traditional patients has been the topic of anthropological research for the last thirty years. Myths have been and constructed and rejected, one being that patients with chronic and less incapacitating illness see rather traditional healers than allopathic medical treatment. The case study with which we are concerned in this paper is the illness of a young girl who is the age in which she is expected to accept a marriage contract. Since she is obviously not willing to do she adopts an illness behaviour which enables her to postpone all role expectations of her age group. She performs a behaviour which is socially accepted and guarantees all the support from her family which she needs and requires. The paper investigates the causes, reason and development of her spirit possession and relates it to the cultural grammar of the patient's group of reference. The data of this case study were obtained at a Muslim shrine in Gujarat, India. PMID:22557510

    Introduction. HBV genotypes and subtypes are useful clinical and epidemiological markers. In this study prevalent HBV genotypes were assessed in relation to serological profile and clinical status. Material & Methods. 107 cases of HBV were genotyped. Detailed clinical history was elicited from them. HBsAg, HBeAg, anti-HBs, anti-HBe, and anti-HBc-IgM were assessed. HBV genotyping was performed using Kirschberg's type specific primers (TSP-PCR), heminested PCR, and Naito's monoplex PCR. Nucleotide sequencing was performed. Results. A total of 97 (91%) were genotyped following the methods of Kirschberg et al./Naito et al. Genotype D was by far the most prevalent genotype 91 (85.04%) in this region. A surprising finding was the detection of genotype F in 5 (4.67%) of our patients. Genotype A strangely was observed only in one case. In 85.7% genotype D was associated with moderate to severe liver disease, 43.9% HBeAg, and 18.7% anti-HBc-IgM positivity. Majority of genotype F (80%) was seen in mild to moderate liver disease. It was strongly associated with HBeAg 60% and 20% anti-HBc-IgM positivity. Conclusion. Emergence of genotype F in India merits further study regarding its clinical implications and treatment modalities. Knowledge about HBV genotypes can direct a clinician towards more informed management of HBV patients. PMID:24381592

    We report the seismogenic liquefaction signatures observed in the Kopili Fault Zone of the Brahmaputra plains, NE India. This seismically active zone has previously been identified as the "Assam seismic gap" and thus necessitates understanding its past seismicity and implied seismic hazard. With this objective, paleo-seismic studies using seismogenic liquefaction features have been carried out in this region largely covered with the flood plain deposits of Kopili and Kalang rivers. The trenches excavated at two locations revealed extensive liquefaction features with more than 20 sub parallel sand dykes having major orientation in NE-SW direction. A total of 29 samples from marker horizons have been processed to constrain chronology of the liquefaction features using optically stimulated luminescence (OSL) and 14C (AMS) dating techniques. The age constraints in terms of respective lower and upper bound age brackets for individual dykes suggest three time intervals of their formations i.e. (i) 250 ± 25 yr. BP, (ii) between 400 to 770 yr. BP and (iii) 900 ± 50 yr. BP. These new ages of liquefaction features correspond to the occurrence timings of causative seismic events which are in addition to the known historical earthquakes and thus enhance our understanding of the paleoseismic history of this region during past ~ 1000 years.

    Bloodstream infections are associated with significant patient morbidity and mortality worldwide. In this study, we examined antimicrobial susceptibility patterns by reviewing the data on 5,704 blood samples that were collected from patients with fever/sepsis admitted to Government Medical College and Hospital, Chandigarh, India, over a period of 1 year from August 2003 to July 2004. Among the 567 qualifying samples, Pseudomonas aeruginosa (19.75%), Escherichia coli (15.17%), Klebsiella pneumoniae (14.99%), and Salmonella enterica serovar Typhi (12.87%) were the most frequently isolated Gram-negative bacteria other than Citrobacter, Acinetobacter, Proteus, and Enterobacter spp. collectively accounting for 80.96% of the isolates. Staphylococus aureus (13.86%) and Enterococcus feacalis (2.35%) were most frequently isolated Gram-positive bacteria other than other Streptococcus and Staphylococcus spp. collectively accounting for 18% of the isolates. Among the antibiotics used for susceptibility testing of Gram-negative isolates, amikacin showed higher activity (76.61%) against Enterobacteriaceae and ciprofloxacin (65.17%) against non-fermenters. However, cefoperazone + sulbactum showed the highest activity (82.66%) among all Gram-negative isolates. For Gram-positive isolates, vancomycin (100%), ciprofloxacin (89.74%) showed the highest activity against Staphylococcus spp. Combinations of antibiotics are often prescribed as emperic therapy for bacteremia, especially for Gram-negative pathogens. Hence the antibiotic susceptibility patterns of blood isolates reported here may be a useful guide for physicians initiating emperic therapy with antibiotics.

    Background: Preeclampsia in pregnancy has been shown to be associated with low serum calcium level. Though the evidence is abundant, it is equivocal. Objectives: The study aimed to estimate the dietary calcium intake and serum calcium status among pregnant women, and to document the association of the dietary calcium intake and serum calcium status with incidence of preeclampsia in the 3rd trimester of pregnancy. Materials and Methods: A community-based cross-sectional study was conducted in the Health and Demographic Surveillance System (HDSS) site, Ballabgarh, Haryana, India. All pregnant women between 28 weeks and 36 weeks of gestation were interviewed. A semi-structured interview schedule and a 24-h dietary recall questionnaire were administered to assess the dietary calcium intake. AutoAnalyser (Biolis 24i) was used for measuring serum calcium. Results: We enrolled 217 pregnant women. The mean [standard deviation (SD)] dietary calcium intake was 858 (377) mg/day. The mean (SD) serum calcium level was 9.6 mg/dL (0.56). Incidence of preeclampsia was 13.4%. Preeclampsia was not associated with hypocalcemia [odds ratio (OR) = 1.2 95% confidence interval (CI); 0.27-3.98]. Conclusion: The majority of pregnant women had inadequate dietary calcium intake. The prevalence of hypocalcemia was low. Low serum calcium level was not associated with preeclampsia. Calcium supplementation may not reduce preeclampsia in this population. PMID:27385877

    Present study was aimed to find out dimension and socio-demographic correlates of domestic violence in Assam, Sikkim and Meghalaya, Northeast India. Two districts from each state were selected at random and women aged 18-35 years from rural and urban localities were interviewed to obtain relevant information. The study included a total of 2249 participants (Rural = 1577 and Urban = 672) from Assam (650), Sikkim (1148) and Meghalaya (451). Domestic violence was recorded in 26.4% of study participants and highest in Meghalaya. Of all types, psychological violence was predominant. A number of socio-demographic factors have been identified as independent predictors for domestic violence in pooled and state specific analysis. Findings of our study may help in formulating strategies to prevent domestic violence.

    The supply of good quality food is main necessity for economic and social health of urban and rural population throughout the globe. This study comes to know the severity of As in the west Bengal and north-eastern states of the India. Over the 75% large population of India lives in villages and associated with farming and its related work. West Bengal is the densest populated area of India, fish and rice is the staple food as well as in north-eastern states. For the fulfil demand of fish large population the area are used fisheries as the business. Arsenic contamination in ground water is major growing threat to worldwide drinking water resources. High As contamination in water have been reported in many parts of the world Chandrasekharam et al., 2001; Smedley and Kinniburgh, 2002; Farooq et al., 2010). In context to West Bengal and north-east states of India arsenic is main problem in the food chain. These areas are very rich in arsenic many fold higher concentrations of Arsenic than their respective WHO permissible limits have been reported in the water. Over the 36 million people in Bengal delta are at risk due to drinking of As contaminated water (Nordstrom, 2002). The highest concentration of arsenic (535 μg/L Chandrashekhar et al. 2012) was registered from Ngangkha Lawai Mamang Leikai area of Bishnupur district which is fifty fold of the WHO limit for arsenic and tenfold of Indian permissible limit. With the continuous traditional practicing (As rich water pond) and untreated arsenic rich water in fish industries leads to health hazards. A sustainable development in aquaculture should comprise of various fields including environmental, social, cultural and economic aspects. A scientific study has to be needed for the overcome on this problem and rain harvested water may be used for reduce the arsenic problems in fisheries.

    Pseudotachylitic breccia (PTB) occurs in a drill core from the crater floor of the 11 km diameter, Proterozoic Dhala impact structure, India. PTBs were intersected in late Archean granitoids between 348.15 m and 502.55 m depth in the MCB-10 drill core from the center of the Dhala structure. The breccias comprise both cataclastic-matrix as well as melt breccias. The presence of microlites and vesicles in the groundmass and a widely observed flow fabric in the PTB support the presence of melt in the groundmass of some samples. Clasts in PTB are derived from the Archean granitoid basement. PTB matrix, the matrix of impact melt breccia also occurring between 256.50 m and 502.55 m depth, and the target granitoids vary in terms of silica, total alkali, magnesium and iron oxide contents. Chondrite-normalized REE patterns of PTB and target granitoids are similar, but the elemental abundances in the PTB are lower. The restricted size of PTB as veins and pods of up to 2.5 cm width, their occurrence at varied depths over a core length of 150 m, the clast population, and the chemical relationships between PTB and their host rocks all suggest the derivation of these breccias locally from the fractured basement granitoids involving in-situ melting. We favor that this took place due to rapid decompression during the collapse and modification stage of impact cratering, with, locally, additional energy input from frictional heating. Locally, amphibolite and dioritic mylonite occur in the host granitoids and their admixture could have contributed to the comparatively more mafic composition of PTB. Alteration of these crater floor rocks could have involved preferential reduction of silica and alkali element abundances, possibly due to impact-induced hydrothermal activity at crater floor level. This process, too, could have resulted in more mafic compositions.

    Background: Urinary tract infections (UTIs) remain a major problem both in hospitalized and outdoor patients. Multidrug-resistant enterococci are emerging as a major nosocomial pathogen with increasing frequency. However, the incidence of community-acquired enterococcal infections and species prevalent in India is not thoroughly investigated. Objectives: This study aims to estimate the burden of community-acquired UTIs seen at a tertiary care hospital and to identify the Enterococcus species isolated from these patients. The study also aims to determine the antibiotic susceptibility pattern with reference to high-level aminoglycosides and vancomycin. Materials and Methods: Semi-quantitative cultures from a total of 22,810 urine samples obtained from patients seen at various Outpatient Departments were analyzed. From them 115 nonduplicate isolates of enterococci were obtained as significant pure growth (>105 cfu/ml) and speciated. Antibiotic susceptibility was performed by Kirby–Bauer disc diffusion method. Vancomycin resistance screening was performed by the vancomycin screen agar method recommended by Clinical and Laboratory Standards Institute and confirmed by determination of minimum inhibitory concentration by agar dilution method. Results: Of 115 enterococcal isolates, 61 were identified as Enterococcus faecalis, 42 as Enterococcus faecium, 3 each as Enterococcus dispar, and Enterococcus pseudoavium. High-level gentamicin resistance (HLGR) was higher in E. faecium (47.6%) than E. faecalis (32.7%) and HLSR also showed the same pattern with 47.6% and 27.9% resistance, respectively. Vancomycin resistant enterococci accounted for 11.3% of the isolates, and out of them 53.8% were E. faecium by agar dilution method. Conclusion: High rate of resistance to antibiotics of penicillin group and aminoglycosides was observed in our tertiary care hospital even in community acquired UTIs. Hence, there is an urgent need for more rational and restricted use of antimicrobials

    Background Data on eye diseases among school children is not readily available. Considering the fact that one-third of India's blind lose their eyesight before the age of 20 years and many of them are under five when they become blind, early detection and treatment of ocular morbidity among children is important. Aim To estimate the prevalence of ocular morbidity among school children of age 6-16 years. Settings Government and private coeducational schools in urban area of Shimla. Design Cross-sectional Materials and Methods Government and private coeducational schools selected by stratified random sampling. About 1561 school children, studying in elementary through secondary class in these schools were examined from August 2001 to January 2002 in Shimla. A doctor did visual acuity and detailed ophthalmic examination. Statistical analysis The Chi-square test was used to test differences in proportions. Differences were considered to be statistically significant at the 5% level. Results Prevalence of ocular morbidity was 31.6% (CI=29.9-32.1%), refractive errors 22% (CI=21.1-22.8%), squint 2.5% (CI=2.4-2.6%), color blindness 2.3% (CI=2.2-2.4%), vitamin A deficiency 1.8 % (CI=1.7-1.9%), conjunctivitis 0.8% (CI=0.79-0.81%). Overall prevalence of ocular morbidity in government and private schools did not show any statistical significant difference. Prevalence of conjunctivitis was significantly (P<0.5) more in government schools. Conclusion A high prevalence of ocular morbidity among high-school children was observed. Refractive errors were the most common ocular disorders. PMID:19237787

    Opportunity for natural selection among five population groups of Manipur in comparison with other North East Indian population has been studied. Crow's index as well as Johnston and Kensinger's index for natural selection were calculated based on differential fertility and mortality. The mortality component was found to be lower compared to fertility component in all the populations which may attribute to comparatively improved and easily accessible health care facilities. However, different selection pressures, artificial and natural, seem to be influencing the selection intensity through induced abortion and spontaneous abortion among the two non-tribal migrant groups: Bamon and Muslims, respectively. This study highlights the probable interaction of artificial and natural selection in determining the evolutionary fate of any population group.

    Over the last fifty years, changes in agriculture brought about by the Green Revolution have transformed India from a famine-prone, drought-susceptible country into the worlds' third largest grain producer and one of the most intensively irrigated parts of the globe. Regionally, cheap energy, subsidised seeds and fertilisers, and in some areas Government purchase guarantees for grain promote the intensification of farming. While this allows farmers to survive, it also aggravates the drain agriculture is having on resources, particularly energy and water. Analysis at a regional scale, however, masks the considerable spatial variability that exists on a more localised level and must be taken into consideration to understand correctly aggregate system response to policy, hydrologic, and climatic change. In this study we present and analyse the results from over 100 farmer interviews conducted in the data-scarce districts of Jalaun and Sitapur on the Gangetic Plains of Uttar Pradesh during the post monsoon period of 2013. Variables such as the volumes and timing of irrigation water applied, sources of water, methods of abstraction and irrigation, and costs incurred are mapped, using qualitative data analysis and GIS. Large differences between the districts emerge, for instance in the region of Jalaun where cheaper canal water is available in addition to groundwater. This has enabled farmers to afford more water efficient technologies such as sprinklers, a practice not found in Sitapur which depends almost exclusively on more expensive diesel pumps. Results are used to delineate the spatial variability in water use practices, along with farmer behaviour and decision making. The primary data are compared with socio-economic information taken from regionally produced statistical abstracts. The combined data are used to identify the main drivers that influence farmer decision-making, which is in turn leading to groundwater overdraught in many parts of North India. Finally

    North East India, nestled between the southeastern Tibetan Plateau on the north, the Indo Myanmar range of hills to the east, plains of Bangladesh to the south and the Indo-Gangetic plains (IGP) to the west has a unique topography and population inhabitation pattern. In recent decades, along with other parts of south Asia NE India has undergone rapid industrial and economic development. Lifestyle changes have increasingly added to the anthropogenic burden on the atmosphere in the plains while biomass burning due to shifting cultivation in the hills is a major source of particulate and gaseous pollution. Studies have suggested that during the Asian summer monsoon, boundary layer pollution from India, Southeast Asia and south China are lifted to the upper tropospheric region by convection followed by westward transport over the Middle East and the Mediterranean. The spatio-temporal variation of aerosol optical (viz. AOD, AAI, AAOD, AE, FMF, columnar mass concentration (CMC)) and radiative properties are studied using data from multiple satellite sensors: MODIS, OMI, TOMS, CERES at various locations within the NE India (22-30°N, 86-98°E) for the period 2000-2012. Significant spatio-temporal variation of aerosol optical and radiative properties is observed within the region. For example, Guwahati, the metropolitan city, shows maximum value of AOD, followed by Dhubri the location situated at the western corridor of north-east India. Minimum AOD is observed at the high altitude locations Thimphu and Tawang. Temporally AOD is overriding in March, April, May (MAM) at almost all the observation locations. The minimum AOD over the region in October-November (ON) is associated with the topography and local meteorology. AAI >0.5 at all the locations indicates presence of significant amount of absorbing aerosols. The peak AAI and AAOD in MAM at all the location is associated with the peak biomass burning activity and long range transportation from other locations of India and

    Aim: This study was conducted to determine the incidence of major reproductive problems of dairy cattle reared under a semi-intensive system by small and marginal farmers in Meghalaya province of North-Eastern India. Materials and Methods: In a 3 years study, a total of 576 crossbred dairy cattle (212 Holstein Friesian cross and 364 Jersey cross) from all districts (n=11) of Meghalaya were assessed with the survey, clinical examination, and personal observations. Results: Out of the total animal assessed, 33.85% (n=195) were found to be affected with one or more of the clinical reproductive problems. Repeat breeding (RB), anestrus, retention of fetal membrane, and abortion were found to be the major clinical reproductive problems. Out of the total animal affected with reproductive disorders, the incidence of anestrus, RB, retention of fetal membrane, and abortion was found to be 31.79% (n=62), 24.61% (n=48), 14.35% (n=28), and 11.25% (n=22), respectively. In addition, dystocia (5.12%), prolapse (1.53%), endometritis (4.61%), and pyometra (6.66%) were minor clinical reproductive problems. There was a significant difference in the incidence of reproductive disorders with respect to breed, age, and parity. Conclusion: It was revealed from this study that RB, anestrus, retention of fetal membrane, and dystocia are the major clinical reproductive problems in Meghalaya. Results indicated unsatisfactory feeding, housing, and health management practices are the main cause of low fertility of dairy cows. Lack of scientific knowledge, low access to breeding, and health services further contributed to low productivity and fertility. PMID:27284229

    Trend analysis of hydro-climatic variables such as streamflow, rainfall, and temperature provides useful information for effective water resources planning, designing, and management. Trends in observed streamflow at four gauging stations in the Gomti River basin of North India were assessed using the Mann-Kendall and Sen's slope for the 1982 to 2012 period. The relationships between trends in streamflow and rainfall were studied by correlation analyses. There was a gradual decreasing trend of annual, monsoonal, and winter seasonal streamflow ( p < 0.05) from the midstream to the downstream of the river and also a decreasing trend of annual streamflow for the 5-year moving averaged standardized anomalies of streamflow for the entire basin. The declining trend in the streamflow was attributed partly to the increased water withdrawal, to increased air temperature, to higher population, and partly to significant reducing trend of post monsoon rainfall especially at downstream. Upstream gauging station showed a significant increasing trend of streamflow (1.6 m3/s/year) at annual scale, and this trend was attributed to the significant increasing trend of catchment rainfall (9.54 mm/year). It was further evident in the significant coefficient of positive correlation ( ρ = 0.8) between streamflow and catchment rainfall. The decreasing trend in streamflow and post-monsoon rainfall especially towards downstream area with concurrent increasing trend of temperature indicates a drying tendency of the Gomti River basin over the study period. The results of this study may help stakeholders to design streamflow restoration strategies for sustainable water management planning of the Gomti River basin.

    2016-01-01

    Background & objectives: Fluoroquinolone resistance in both Gram-positive and Gram-negative bacteria has increased with the widespread use of fluoroquinolones. Fluoroquinolone resistance in Gram-negative bacilli has been widely studied, though staphylococci and enterococci are also notably resistant. Enterococci being the second most common cause of healthcare-associated urinary tract infections (UTIs) fluoroquinolones are often the drug of choice. This study was undertaken to assess the risk factors associated with fluoroquinolone-resistant enterococcal UTI in a tertiary level health facility in north India. Methods: A total of 365 patients with UTI caused by enterococci were studied over a period of two years. Patients with ciprofloxacin-resistant and susceptible UTI were considered as cases and controls, respectively. Resistance profile of the isolates against common antibiotics was studied by minimum inhibitory concentration (MIC) determination. Mechanisms for fluoroquinolone resistance was studied by efflux pump inhibitor activity and multiplex PCR targeting the qnr genes. Results: A total of 204 (55.89%) cases and 161 (44.1%) controls were identified. The fluoroquinolone-resistant isolates were significantly resistant to ampicillin, high strength aminoglycosides and vancomycin. The majority (78%) of the resistant isolates showed efflux pump activity. Treatment in indoor locations, presence of urinary catheters and pregnancy along with recent exposure to antibiotics especially fluoroquinolones, third generation cephalosporins and piperacillin-tazobactam were identified as independent risk factors. Interpretation & conclusions: Our results showed that fluoroquinolone resistance in enterococcal UTI was largely associated with indoor usage of antibiotics and use of indwelling devices. Knowledge of risk factors is important to curb this emergence of resistance. PMID:28256471

    Introduction: Occupational hazards such as accidental exposure to sharp, cuts, and splashes are common among health-care workers (HCWs). Aims and Objectives: To determine the occurrence of self-reported occupational exposures to these hazards and to know the prevalent practices following the exposure. The second aim was to know the baseline antibody levels against hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) immediately after these accidents. Methods: An observational prospective study was done in the HCWs of a tertiary care academic health organization of North India from January 2011 to December 2013. At the time of self-reporting of injury, a questionnaire was administered. Blood sample of HCWs and of the source, if identified, was collected for baseline HBV, HCV, and HIV serum markers. The exposed HCWs were followed up and repeat testing was done after 3–4 weeks for seroconversion up to 6 months. Results: A total of 476 injuries were reported. Needlestick injury of fingers was the most common. Doctors were found to have the highest exposure rate (73.7%) distantly followed by nurses (19.1%). A significant number of the HCWs (125, 26.3%) vaccinated in past had hepatitis B surface antibody (anti-HBs) titers <10 mIU/mL (protection defined as anti-HBs level ≥10 mIU/ml). Only 44 sources were found to be seropositive (11 for HIV, 9 for HCV, and 24 for HBV). No seroconversion was seen in any of the exposed HCWs after 6 months. Conclusions: The incidence of needlestick and sharp injuries is most often encountered in emergency wards. Anti-HBs titers were suboptimal in many of the HCWs requiring a booster dose of HBV vaccination. PMID:28042212

    Central nervous system (CNS) involvement is a known complication of scrub typhus which range from mild meningitis to frank meninigoencephalitis. Aims and objectives: To study the clinical feature, laboratory parameters and response to treatment of scrub typhus meningitis/meningoencephalitis. Methods and Materials: This is a hospital based prospective observational study from North Eastern India. Diagnosis was based on clinical features and positive serological test (Weil's Felix test and IgM antibody card test). Results: 13 patients of scrub typhus with features of meningitis/meningoencephalitis were included. The mean duration of fever before presentation was 5.61±3.08 days and 4 (30.76 %) patients had eschar. Altered sensorium, headache, seizure and meningeal sign were present in 13 (100%), 13 (100%), 6 (46.15%) and 10 (76.92%) patients respectively. Mean CSF protein, glucose and Adenosine deaminase was 152.16±16.88mg/dl, 55.23±21.7mg/dl, and 16.98±7.37U/L respectively. Mean total count of CSF leukocyte and lymphocyte percentage was 46.07±131 cell/cumm and 98.66±3.09% respectively. Tablet doxycycline with or without injection azithromycin was used and that shows good response 15.38% of patients died and all of them had multi organ dysfunction. Conclusion: Meningoencephalitis is a common manifestation of scrub typhus and diagnosis requires high degree of clinical suspicion which if diagnosed early and specific treatment started, patients usually recover completely with few complications.

    Summary Background To diagnose and characterize the perianal fistulous disease using Magnetic resonance imaging (MRI) in a hilly and rural area of North India. Material/Methods This prospective hospital based study was conducted for a period of one year from April 2014 to April 2015 in the departments of Radiodiagnosis and Surgery of our institute. A total of 50 consecutive patients presenting with perianal fistulous disease fulfilling the inclusion and exclusion criteria were included in the study and taken up for MRI. The perianal fistulae were classified according to St James University hospital classification and tracks were assessed with regard to anatomical plane, length, ramifications, abscess formation, enteric communication, external cutaneous opening, enhancement and suprasphincteric extension. Surgical correlation was done in 31 patients who opted for surgical treatment. Rest of the 19 patients preferred alternative medicine for treatment or chose to postpone their surgery. Results The disease was much more prevalent in males in comparison to females with male to female ratio of 24:1. Grade 4 was the most common type of fistula (34%) while Grade 5 was the least common type (4%).MRI showed a high sensitivity of 93.7% and positive predictive value (PPV) of 96.7% when correlated with surgical findings. A substantial number of patients (38%) preferred alternative medicine or non surgical form of treatment. Conclusions MRI is a very sensitive modality for the evaluation of perianal fistula. In our study group, the disease predominantly affected middle aged men. Ramifications and abscesses were commonly seen, affecting nearly half of the patients and majority of the patients had active fistulous tracks with posteriorly located enteric opening. Overall, transsphincteric fistulae were most common. Significant number of patients avoided surgery or showed preference for non surgical treatment. PMID:28096904

    Clay mineral assemblages of a soil chrono-association comprising five fluvial surface members (QGH1 to QGH5) of the Indo-Gangetic Plains between the Ramganga and Rapti rivers, north-central India, demonstrate that pedogenic interstratified smectite-kaolin (Sm/K) can be considered as a potential indicator for paleoclimatic changes during the Holocene from arid to humid climates. On the basis of available radiocarbon dates, thermoluminescence dates, and historical evidence, tentative ages assigned to QGH1 to QGH5 are <500 yr B.P., >500 yr B.P., >2500 yr B.P., 8000 TL yr B.P., and 13,500 TL yr B.P., respectively. During pedogenesis two major regional climatic cycles are recorded: relatively arid climates between 10,000-6500 yr B.P. and 3800-? yr B.P. were punctuated by a warm and humid climate. Biotite weathered to trioctahedral vermiculite and smectite in the soils during arid conditions, and smectite was unstable and transformed to Sm/K during the warm and humid climatic phase (7400-4150 cal yr B.P.). When the humid climate terminated, vermiculite, smectite, and Sm/K were preserved to the present day. The study suggests that during the development of soils in the Holocene in alluvium of the Indo-Gangetic Plains, climatic fluctuations appear to be more important than realized hitherto. The soils older than 2500 yr B.P. are relict paleosols, but they are polygenetic because of their subsequent alterations.

    BACKGROUND Breast cancer is one of the most common malignancies in women and is associated with a variety of risk factors. The functional single-nucleotide polymorphism (SNP) C677T in the gene encoding 5,10-methylenetetrahydrofolate reductase (MTHFR) may lead to decreased enzyme activity and affect the chemosensitivity of tumor cells. This study was designed to investigate the association of MTHFR gene polymorphism (SNP) in the pathogenesis of breast cancer among the North Indian women population. MATERIALS AND METHODS Genotyping was performed by polymerase chain reaction (PCR) using genomic DNA, extracted from the peripheral blood of subjects with (275 cases) or without (275 controls) breast cancer. Restriction fragment length polymorphism was used to study C677T polymorphism in the study groups. RESULTS The distribution of MTHFR (C677T) genotype frequencies, ie, CC, TT, and CT, among the patients was 64.7%, 2.18%, and 33.09%, respectively. In the healthy control group, the CC, TT, and CT frequencies were 78.91%, 1.09%, and 20.1%, respectively. The frequencies of C and T alleles were 81.2% and 18.7%, respectively, in the patient subjects, while they were 88.9% and 11.09%, respectively, among the healthy control group. Frequencies of the CT genotype and the T allele were significantly different (P = 0.007 and P = 0.005, respectively) between the control and the case subjects. CONCLUSION This study shows an association of the CT genotype and the T allele of the MTHFR (C667T) gene with increased genetic risk for breast cancer among Indian women. PMID:27721657

    Forest fires are a major environmental problem in North East Region (NER) with large tracts of forest areas being affected in every season. Forest fires have become a major threat to the forest ecosystems in the region, leading to loss of timber, biodiversity, wildlife habitat and loss to other natural resources. Studies on forest fire have reported that about 50% of forest fire in the country takes place in NE region. The forest fire in NER is anthropogenic in nature. The forest fire hazard map generated based on appropriate weightage given to the factors affecting fire behavior like topography, fuel characteristic and proximity to roads, settlements and also historical fire locations helped to demarcate the fire prone zones. Whereas, during fire season the weather pattern also governs the fire spread in the given area. Therefore, various data on fuel characteristics (land use/land cover, forest type map, forest density map), topography (DEM, slope, aspect) proximity to settlement, road, waterbodies, meteorological data from AWS on wind speed, wind direction, dew point have been used for each fire point to rank its possible hazard level. Near real time fire location data obtained from MODIS/FIRMSwere used to generate the fire alerts. This work demonstrates dissemination of information in the form of maps and tables containing information of latitude and longitude of fire location, fire occurrence date, state and district name, LULC, road connectivity, slope and aspect, settlements/water bodies and meteorological data and the corresponding rating of possibility of fire spread to the respective fire control authorities during fire season.

    The Daling Thrust (DT) delineates a zone of intense shear localization in the Lesser Himalayan Sequence (LHS) of the Darjeeling-Sikkim Himalaya. From microstructural studies of deformed quartzite samples, we show a transition in the dynamic recrystallization mechanism with increasing distance from the DT, dominated by grain boundary bulging (BLG) recrystallization closest to the DT, and progressively replaced by sub-grain rotation (SGR) recrystallization away from the thrust. The transition is marked by a characteristic variation in the fractal dimension (D) of grain boundaries, estimated from the area-perimeter method. For the BLG regime, D ≈ 1.046, which decreases significantly to a value as low as 1.025 for the SGR regime. Using the available thermal data for BLG and SGR recrystallization, we infer increasing deformation temperatures away from the DT in the hanging wall. Based on the quartz piezometer our estimates reveal strong variations in the flow stress (59.00 MPa to 16.00 MPa) over a distance of ~ 1.2 km from the DT. Deformation mechanism maps constructed for different temperatures indicate that the strain rates (10- 12 S- 1 to 10- 14 S- 1) comply with the geologically possible range. Finally, we present a mechanical model to provide a possible explanation for the cause of stress intensification along the DT.

    This observational study during the 29-year period from 1979 to 2007 evaluates the potential role of Eurasian snow in modulating the North East-Indian Summer Monsoon Rainfall with a lead time of almost 6 months. This link is manifested by the changes in high-latitude atmospheric winter snow variability over Eurasia associated with Arctic Oscillation (AO). Excessive wintertime Eurasian snow leads to an anomalous cooling of the overlying atmosphere and is associated with the negative mode of AO, inducing a meridional wave-train descending over the tropical north Atlantic and is associated with cooling of this region. Once the cold anomalies are established over the tropical Atlantic, it persists up to the following summer leading to an anomalous zonal wave-train further inducing a descending branch over NE-India resulting in weak summer monsoon rainfall.

    Limitation over region specific data on dust morphology (particle shape, size) and mineralogy gives rise to uncertainty in estimation of optical and radiative properties of mineral dust (Mishra and Tripathi, 2008; Mishra et al., 2008). To address this issue over Indian arid zone (local source of mineral dust), a short field campaign was organized in Jodhpur, located in Rajasthan, a north western state of India, over seven sites (four in city and three far from city) with varying altitudes in June 2013. Jodhpur lies in vicinity of the Thar Desert of Rajasthan. Particles were collected on pure Tin substrates for individual particle morphological and elemental composition analysis using Scanning Electron Microscope (SEM) equipped with Energy Dispersive Spectrometer (EDS). The morphological parameters (e.g. Aspect ratio; AR, Circulatory parameter; CIR.) were retrieved following Okada et al. (2001) using Image J software. Columnar spectral aerosol optical thickness has been measured by Microtops-II sun photometer for a set of five wavelengths (380 to 1020 nm) over all the sites in tandem with regional aerosol collection. SEM analysis reveals that the particles close to spherical shape (AR range 1.0-1.2) were found to be ~ 18% whereas particles with AR range 1.2-1.4 were found to be abundant (25%) followed with that of AR range 1.4-1.6 and 1.6-1.8 (each ~ 17%) and 1.8-2.0 (~ 14%) while the particles with AR >2 (highly non-spherical) were found to be ~ 8%. Here, it is noteworthy to mention that AR=1 for spherical particle while increasing AR (>1) exhibit increasing non-sphericity of particles. The EDS analysis reveals that 43% particles were observed with low hematite (H ≤ 1%; volume percentage), 24% (H 1-2 %), 14% (H 2-3%), 5% (H 3-4%) and 14% (H >4%). The aforementioned proportions will be extremely useful for simulating the optical and radiative properties of regional aerosols. From the Microtops-II observations, Ångström exponent for spectral interval of 380 to

    Background: Research into substance use disorders (SUD) has been unable to unequivocally demonstrate effectiveness of treatment modalities. Aims: The aim of the study was to study the long-term outcome after in-patient treatment in a cohort of patients admitted for SUD in a deaddiction unit of a hospital in North India. Materials and Methods: The case notes of all in-patients with a primary diagnosis of alcohol and/or opioid dependence syndrome (F10.24 and F11.24) in the calendar year 2006 were examined. All patients without any physical or mental comorbidity other than comorbid SUD were included in the study. They were contacted telephonically or their case notes examined in September, 2007. Status regarding abstinence or relapse was determined and data was analyzed. Independent samples t-test and chi-square test were used for determining significance of difference between continuous and categorical variables respectively. Kaplan-Meier analysis was applied to find the survival times of different groups with the duration to relapse as variable of interest. Log rank test was applied to find the significance of differences in various groups. Cox's Regression analysis was applied to find the hazard ratio. Results and Conclusions: Data for 59.22% of patients included in the study were available for analysis. Mean survival time was 36.35 weeks (28.74-43.95, 95% CI) for patients across different groups, 36.71 weeks (26.24-47.18, 95% CI) for the alcohol group, 34.00 weeks (8.37-59.36, 95% CI) for natural opioids group, 37.53 weeks (26.33-48.73, 95% CI) for semi/synthetic opioids group and 17.00 weeks (3.39-30.60, 95% CI) for the mixed group. Kaplan-Meier analysis revealed that those who were following-up at time of evaluation had significantly longer durations to relapse. Deaddiction services should stress on keeping patients on follow-up as a means to better outcomes. PMID:19823613

    Background & objectives: The indiscriminate use of third generation cephalosporin has contributed to the emergence and widespread dissemination of extended spectrum β lactamases (ESBL) genes in Klebsiella pneumoniae. This study was undertaken to elaborate the genetic behaviour of ESBL - producing K. pneumoniae isolates in the neonatal intensive care unit (NICU) of a tertiary care hospital in north India causing successive outbreaks in context with empirical third generation cephalosporin use. Methods: Isolates of K. pneumoniae (43 from blood, 3 from pus and endotracheal tube, 4 from environment) causing successive outbreaks in the NICU of a tertiary care university hospital were studied for two years. Antimicrobial susceptibility testing was done by disc diffusion and minimum inhibitory concentration (MIC) determination by agar dilution methods. ESBL production was determined by phenotypic and genotypic methods. Clonal relatedness among the isolates was studied by enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR). Genetic environment of these isolates was assessed by the presence of integrons and gene cassettes. Transformation experiments were done, and plasmids of these isolates were characterized by stability testing and incompatibility testing. Subsequently, a change in the ongoing antibiotic policy was adopted, and corresponding changes in the behaviour of these isolates studied. Results: During the period from August 2011 to January 2013, 46 isolates of monoclonal ESBL K. pneumoniae were obtained from different neonates and four similar environmental isolates were studied. Multidrug-resistant ESBL isolates harboured both blaCTXM-15 and blaSHV-5. The dfr and aac-6’ resistant genes were found in gene cassettes. A 50 kb plasmid belonging to IncFIIA group was detected in all the isolates which was transferable and stable. The emergence and regression of the outbreaks coincided with antibiotic usage in the NICU, with widespread

    Identifying with a group can contribute to a sense of well-being. The mechanisms involved are diverse: social identification with a group can impact individuals' beliefs about issues such as their connections with others, the availability of social support, the meaningfulness of existence, and the continuity of their identity. Yet, there seems to be a common theme to these mechanisms: identification with a group encourages the belief that one can cope with the stressors one faces (which is associated with better well-being). Our research investigated the relationship between identification, beliefs about coping, and well-being in a survey (N = 792) administered in rural North India. Using structural equation modelling, we found that social identification as a Hindu had positive and indirect associations with three measures of well-being through the belief that one can cope with everyday stressors. We also found residual associations between participants' social identification as a Hindu and two measures of well-being in which higher identification was associated with poorer well-being. We discuss these findings and their implication for understanding the relationship between social identification (especially with large-scale group memberships) and well-being. We also discuss the application of social psychological theory developed in the urban West to rural north India. © 2014 The Authors.

    In present pilot study aimed to estimate, presence of Mycobacterium avium subspecies paratuberculosis (MAP) antibodies in the human serum samples originating from North India using "Indigenous absorbed ELISA kit" (ELISA kit). The phase I, "ELISA kit" was optimized using protoplasmic antigen from native isolate of MAP "Indian Bison type" recovered from the biopsies of Crohn's disease patients. The phase II, sensitivity and specificity of the kit were estimated as 40.0 and 83.3%, respectively, when evaluated in 40 human serum samples (5 Crohn's disease and 22 ulcerative colitis patients and 13 healthy human subjects) with defined MAP status with respect to stool culture. Seroprevalence of MAP antibodies was higher in CD patients (80.0%) as compared to ulcerative colitis patients (4.5%) and normal human subjects (15.3%). The phase III, seroprevalence of MAP antibodies was estimated as 23.4%, on the basis of the screening of 452 human serum samples (without history) from different geographical regions of North India. Region-wise, 34.0, 33.3, 32.8, 25.0, 23.0, 17.7, and 12.5% samples were positive from the states of Punjab, Uttarakhand, New Delhi, Himachal Pradesh, Haryana, Uttar Pradesh and Jammu and Kashmir, respectively. Study reported moderately higher presence of MAP antibodies in human population, which necessitates programs to reduce the bioburden of MAP in the environment and in animal population.

    Introduction: Nasopharyngeal carcinoma (NPC) is a common cancer in the North-East region of India. Though the role of environmental contributors of NPC in the North-Eastern part of India is firmly established, EBV as an etiological agent in the region remains unexplored. Material and Methods: Fifty-one patients, who presented at the department of ENT, NEIGRIHMS and were confirmed as NPC upon histopathological examination, were included in the study. Chromogenic in-situ hybridization (CISH) was used for the evaluation of EBER (Epstein Barr Virus Encoded RNA). Presence of nuclear signals was taken as positive for EBER expression. EBER status was correlated with various clinicopathological parameters like age, sex, dietary habits, histological types of NPC, and ethnicity of the patients. Results: The age range of the study group was 25 to 70 years with a mean age of 44.64 years and a male:female ratio of 3:2. Non-keratinizing undifferentiated type of NPC was the most common histological type. EBV was positive in 59% (30/51) of our cases. It showed a statistically significant correlation with the Naga community (P=0.01), with consumption of smoked food (P=0.02), and cigarette smoking (P=0.02). There was no correlation of EBV with age, sex, lymph node metastasis, stage, and histology. Conclusion: Our result indicates that EBV may be an additional risk factor in the pathogenesis of NPC in this region of India. So apart from lifestyle modification, a future study for a screening test for EBV viral load even in asymptomatic patients may be considered, for determination of disease susceptibility, early diagnosis, and proper management.

    Background: Contamination of water, food, and environment with antibiotic-resistant bacteria poses a serious public health issue. Objective: The objective was to study the bacterial pollution of the natural sources of water in east Sikkim and to determine the antimicrobial profile of the bacterial isolates. Materials and Methods: A total of 225 samples, 75 each during winter, summer, and monsoon season were collected from the same source in every season for bacteriological analysis by membrane filtration method. Antibiotic susceptibility test was performed using standard disc diffusion method. Results: A total of 19 bacterial species of the genera Escherichia, Klebsiella, Proteus, Salmonella, Shigella, Enterobacter, Citrobacter, Morganella, Pseudomonas, Acinetobacter, Flavobacterium, and Serratia were isolated and their antimicrobial sensitivity tested. Generally, most bacterial isolates except Salmonella and Shigella species were found resistant to commonly used antibiotics such as ampicillin (57.5%), trimethoprim/sulfamethoxaole (39.1%), amoxicillin/clavulanic acid (37.4%), cefixime (34.5%), tetracycline (29.1%), ceftazidime (26.3%), ofloxacin (25.9%), amikacin (8.7%), and gentamicin (2.7%) but sensitive to imipenem and piperacillin/tazobactam. Conclusion: Natural sources of water in east Sikkim are grossly contaminated with bacteria including enteropathogens. The consumption of untreated water from these sources might pose health risk to consumers. PMID:25136156

    The transformation of palaeo-continents involve breakup, dispersal and reassembly of cratonic blocks by collisional suturing that develop a network of orogenic (mobile) belts around the periphery of the stable cratons. The nature of deformation in the orogenic belt depends on the complex interaction of fracturing, plastic deformation and diffusive mass transfer. Additionally, the degree and amount of melting during regional deformation is critical as the presence of melt facilitates the rate of diffusive mass transfer and weakens the rock by reducing the effective viscosity of the deformed zone. The nature of strain localization and formation of ductile shear zones surrounding the cratonic blocks have been correlated with Proterozoic-Palaeozoic supercontinent assembly (Columbia, Rodinia and Gondwana reconstruction). Although, a pre-Columbia supercontinent termed as Kenorland has been postulated, there is no evidence that supports the notion due to lack of the presence of shear zones within the Archaean cratonic blocks. In this contribution, we present the detailed structural analysis of ductile shear zones within the Bundelkhand craton. The ductlile shear zone is termed as Bundelkhand Tectonic Zone (BTZ) that extends east-west for nearly 300 km throughout the craton with a width of two-three kilometer . In the north-central India, the Bundelkhand craton is exposed over an area of 26,000 sq. The craton is bounded by Central Indian Tectonic zone in the south, the Great Boundary fault in the west and by the rocks of Lesser Himalaya in the north. A series of tonalite-trondjhemite-granodiorite gneiss are the oldest rocks of the Bundelkhand craton that also contains a succession of metamorphosed supracrustal rocks comprising of banded iron formation, quartzite, calc-silicate and ultramafic rocks. K-feldspar bearing granites intrude the tonalite-trondjhemite-granodiorite and the supracrustal rocks during the time span of 2.1 to 2.5 Ga. The TTGs near Babina, in central

    Background Statistics show an increasing proportion of alcohol and drug use in drivers in more recent times throughout the world. It has been found that among the various human factors, alcohol consumption, using drugs and subsequent driving on the roads are major risk factors. Traffic regulations in India penalises drivers who drive beyond permissible alcohol limit of 30 mg%. Consumption of psychoactive drugs such as opioid, cannabis and benzodiazepines has been reported mainly among youngsters. Hardly any data is available in Indian context particularly from North-West Zone of India. Study objective To study the pattern of alcohol, opioid, cannabis and benzodiazepines use in injured drivers presenting to a designated trauma centre in Chandigarh zone of North-West India. Materials and Methods Consenting injured drivers who presented to the trauma centre in Chandigarh from September 2013 to January 2014 were included. Urine samples collected from the subjects were screened for abusive drug exposure (opioid, cannabis and benzodiazepines) and alcohol using commercial bedside urine immunoassay kits. In urine alcohol positive cases blood samples were collected and analysed for alcohol concentration using standard gas chromatography. Retrograde extrapolation method was used to assess BAC at the time of accident. Results A total of 200 injured drivers were included in this study. We found substance consumption in 54.5% of drivers and alcohol (40.5%) was the most prevalent substance consumed followed by opiates (13%), cannabis (7%) and benzodiazepines (7%). More than one substance was shown in urine of 11.5% of drivers. Among 81 alcohol positive screening cases, the quantitative analysis was successfully done for 76 cases. Except one, all cases showed BAC value more than 30 mg% which is the legal limit for driving any vehicle in India. The values of alcohol concentration in blood at the time of accident were in the range of 20 to 391 mg%. Conclusion This study has shown

    Background/Aims HBV has been classified into ten genotypes (A–J) and multiple subgenotypes, some of which strongly influence disease outcome and their distribution also correlate with human migration. HBV infection is highly prevalent in India and its diverse population provides an excellent opportunity to study the distinctiveness of HBV, its evolution and disease biology in variegated ethnic groups. The North-East India, having international frontiers on three sides, is one of the most ethnically and linguistically diverse region of the country. Given the paucity of information on molecular epidemiology of HBV in this region, the study aimed to carry out an in-depth genetic characterization of HBV prevailing in North-East state of Tripura. Methods From sera of chronically HBV infected patients biochemical/serological tests, HBV DNA quantification, PCR-amplification, sequencing of PreS/S or full-length HBV genomes were done. HBV genotype/subgenotype determination and sequence variability were assessed by MEGA5-software. The evolutionary divergence times of different HBV subgenotypes were estimated by DNAMLK/PHYLIP program while jpHMM method was used to detect any recombination event in HBV genomes. Results HBV genotypes D (89.5%), C (6.6%) and A (3.9%) were detected among chronic carriers. While all HBV/A and HBV/C isolates belonged to subgenotype-A1 and C1 respectively, five subgenotypes of HBV/D (D1–D5) were identified including the first detection of rare D4. These non-recombinant Indian D4 (IndD4) formed a distinct phylogenetic clade, had 2.7% nucleotide divergence and recent evolutionary radiation than other global D4. Ten unique amino acids and 9 novel nucleotide substitutions were identified as IndD4 signatures. All IndD4 carried T120 and R129 in ORF-S that may cause immune/vaccine/diagnostic escape and N128 in ORF-P, implicated as compensatory Lamivudine resistance mutation. Conclusions IndD4 has potential to undermine vaccination programs or anti

    Context: Oral squamous cell carcinoma (OSCC) is the most common malignancy in India and tobacco and betel nut chewing are well established risk factors. Despite successful campaigns to help people shun this habit in developing countries the incidence has rather gone up and HPV and sexual practices are now definitely implicated for this. Aim: An attempt was made to generate Indian data on role of HPV and sexual practices in relation to OSCC. Settings and Design: A prospective observational study was conducted on 50 patients with oral squamous cell carcinoma. Materials and Methods: Tissue biopsies from fifty patients of oral squamous cell carcinoma (OSCC) were subjected to PCR analysis to look for presence of HPV 16 and 18. Fifty patients with benign lesions were taken as control. Statistical Methods Used: The data was statistically analysed using SPSS version 22 and chi square test. Results: 42% of OSCC patients were found to harbour HPV 16 and 18 whereas only 8% of patients with benign lesions had HPV 16 and 18. A significant number of HPV positive patients i.e. 9 out of 21 gave history of multiple sexual partners and oral sex. Conclusions: This high percentage of HPV in OSCC in an Indian population from a tertiary care centre in north India and its association with prevailing sexual practices is quite significant.

    Bemisia tabaci is the major vector pest of agricultural crops all over the world. In this study we report the different bacterial endosymbionts associated with B. tabaci sampled from 14 different locations in North India. Using 16S rDNA clone library sequences we were able to identify Portiera, the primary endosymbiont of B. tabaci, and other secondary endosymbionts like Cardinium, Wolbachia, Rickettsia and Arsenophonus. Along with these we also detected Bacillus, Enterobacter, Paracoccus and Acinetobacter. These secondary endosymbionts were not uniformly distributed in all the locations. Phylogenetic analysis of 16S rDNA sequences of Cardinium, Wolbachia, Rickettsia and Arsenophonus showed that each of these bacteria form a separate cluster when compared to their respective counterparts from other parts of the world. MtCO1 gene based phylogenetic analysis showed the presence of Asia I and Asia II genetic groups of B. tabaci in N. India. The multiple correspondence analyses showed no correlation between the host genetic group and the endosymbiont diversity. These results suggest that the bacterial endosymbiont diversity of B. tabaci is much larger and complex than previously perceived and probably N. Indian strains of the bacterial symbionts could have evolved from some other ancestor.

    Uranium (U) tolerant aerobic heterotrophs were isolated from the subsurface soils of one of the pre-mined U-rich deposits at Domiasiat located in the north-eastern part of India. On screening of genomic DNA from 62 isolates exhibiting superior U and heavy metal tolerance, 32 isolates were found to be positive for P(IB)-type ATPase genes. Phylogenetic incongruence and anomalous DNA base compositions revealed the acquisition of P(IB)-type ATPase genes by six isolates through horizontal gene transfer (HGT). Three of these instances of HGT appeared to have occurred at inter-phylum level and the other three instances indicated to have taken place at intra-phylum level. This study provides an insight into one of the possible survival strategies that bacteria might employ to adapt to environments rich in uranium and heavy metals.

    ABSTRACT An adequate food intake, in terms of quantity and quality, is a key to healthy life. Malnutrition is the most serious consequence of food insecurity and has a multitude of health and economic implications. India has the world's largest population living in slums, and these have largely been underserved areas. The State of Food Insecurity in the World (2012) estimates that India is home to more than 217 million undernourished people. Various studies have been conducted to assess food insecurity at the global level; however, the literature is limited as far as India is concerned. The present study was conducted with the objective of documenting the prevalence of food insecurity at the household level and the factors determining its existence in an urban slum population of northern India. This cross-sectional study was conducted in an urban resettlement colony of South Delhi, India. A pre-designed, pre-tested, semi-structured questionnaire was used for collecting socioeconomic details and information regarding dietary practices. Food insecurity was assessed using Household Food Insecurity Access Scale (HFIAS). Logistic regression analysis was performed to determine the factors associated with food insecurity. A total of 250 women were interviewed through house-to-house survey. Majority of the households were having a nuclear family (61.6%), with mean family-size being 5.5 (SD±2.5) and the mean monthly household income being INR 9,784 (SD±631). Nearly half (53.3%) of the mean monthly household income was spent on food. The study found that a total of 77.2% households were food-insecure, with 49.2% households being mildly food-insecure, 18.8% of the households being moderately food-insecure, and 9.2% of the households being severely food-insecure. Higher education of the women handling food (OR 0.37, 95% CI 0.15-0.92; p≤0.03) and number of earning members in the household (OR 0.68, 95% CI 0.48-0.98; p≤0.04) were associated with lesser chance/odds of being

    Background: Oral and dental injuries contribute to a major part of sports related injuries in children. Trauma occurring in developing years disrupts normal social functioning and brings about a major impact on quality of life due to their cumulative effect. Objectives: To assess the prevalence and causes of various sports related traumatic orodental injuries among 8 to 16 year school students along with identifying the associated risk factors in North India. Patients and Methods: A cross sectional study consisting of high school students of different organized sports teams aged 8-16 years was carried out in geographical area of north India. The students were selected by multistage cluster sampling methodology. 1105 students from 19 school teams (sports teams) and sports academies participated in study through structured interview and clinical examination in different sports situations. Results: 30.3% (n = 335) of students suffered from orodental injuries. A higher number of girls had injury (32%) than boys (29%), though the difference was not significant. Most of the students suffered from soft tissue injuries (48%) followed by tooth fractures (43%). Maximum numbers of injuries were reported in high velocity (44.1%) and medium intensity sports (46.6%) (P < 0.001) Maximum injuries occurred in basketball (50%) and lowest in the field of badminton (6.1%) (P < 0.05). Amateurs (52%) suffered the most from injuries as per level of coaching. Only 6% of boys and 2% of girls used mouthguards. Conclusions: The result of the present study confirmed that students participating in different organized sports at high school level are at a very high risk of getting orodental injury. Hence knowledge and education regarding prevention of traumatic injuries is of paramount importance. PMID:25520762

    Muscodor albus MOW12, an endophytic fungus isolated from Piper nigrum in Mawlong, Meghalaya, India, resembles some cultural and hyphal characteristics of previous isolates of Muscodor sp. In addition, it possesses about 99 % similarity in its ITS rDNA with other M. albus isolates and thus is nicely centered within the genetic tree to other Muscodor spp. This xylariaceae fungus effectively inhibits and kills certain plant pathogenic fungi by virtue of a mixture of volatile compounds that it produces. The majority of these compounds were identified by gas chromatography/mass spectrometry as small molecular weight esters, alcohols, and acids. The main ester components of this isolate of M. albus in its volatile mixture are acetic acid, ethyl ester; propanoic acid, 2-methyl-, methyl ester and acetic acid, 2-methylpropyl ester. This appears to be the first report of any M. albus strain from India.

    Agro-climatic conditions of North-East India are very complex and rice cultivars present in the region have been adapted to grow under harsh environmental conditions. Germplasm present in the region is considered to possess several important and unique traits that are of importance in rice improvement programs. Genetic engineering is a powerful tool to introduce new traits into crop plants. However, not much information is available on the methods to introduce foreign genes into North-East rice cultivars. Therefore, the main objective of this study is to develop transformation procedures for fast recovery of transgenic plants from North-East rice cultivars. To achieve this objective, a systematic study was carried out to identify media components and culture conditions for efficient embryogenic callus induction from the mature seeds and differentiation of callus into plantlets from two North-East deep water rice cultivars, Taothabi and Khongan. Also, role of preculture of callus on Agrobacterium-mediated transformation was studied. Co-cultivation of Agrobacterium with 1-5 days precultured callus was found to result in high frequency of transformation. Detailed characterization of transgenic lines confirmed stable integration of transgenes and expression of reporter gfp gene. The whole process starting from callus induction to regenerating of transgenic rice plants that can be established in the soil was achieved in about 35-45 days. The procedures developed were found to be applicable to a popular variety IR 64. Therefore, methods developed in this study should be useful not only to introduce new traits quickly but also to validate the function(s) of several candidate gene(s) identified under the functional genomics of rice.

    Forests in the mountains are a treasure trove; harbour a large biodiversity; and provide fodder, firewood, timber and non-timber forest products; all of these are essential for human survival in the highest mountains on earth. The present paper attempts a spatiotemporal assessment of forest fragmentation and changes in land use land cover (LULC) pattern using multitemporal satellite data over a time span of around a decade (2000-2009), within the third highest protected area (PA) in the world. The fragmentation analysis using Landscape Fragmentation Tool (LFT) depicts a decrease in large core, edge and patches areas by 5.93, 3.64 and 0.66 %, respectively, while an increase in non-forest and perforated areas by 6.59 and 4.01 %, respectively. The land cover dynamics shows a decrease in open forest, alpine scrub, alpine meadows, snow and hill shadow areas by 2.81, 0.39, 8.18, 3.46 and 0.60 %, respectively, and there is an increase in dense forest and glacier area by 4.79 and 10.65 %, respectively. The change analysis shows a major transformation in areas from open forest to dense forest and from alpine meadows to alpine scrub. In order to quantify changes induced by forest fragmentation and to characterize composition and configuration of LULC mosaics, fragmentation indices were computed using Fragstats at class level, showing the signs of accelerated fragmentation. The outcome of the analysis revealed the effectiveness of geospatial tools coupled with landscape ecology in characterization and quantification of forest fragmentation and land cover changes. The present study provides a baseline database for sustainable conservation planning that will benefit the subsistence livelihoods in the region. Recommendations made based on the present analysis will help to recover forest and halt the pessimistic effects of fragmentation and land cover changes on biodiversity and ecosystem services in the region.

    People who inject drugs (PWID) in India are at high risk for HIV, with women being at elevated risk. Using a socio-ecological framework, this study assessed whether factors associated with HIV transmission risk behaviors differed across men and women PWID. Data for this cross-sectional study were collected from 6449 PWID in 7 cities in Northeast India. Men (n = 5653) and women (n = 796) PWID were recruited using respondent-driven sampling (RDS). We assessed sex differences in two recent HIV transmission risk behaviors: multiple sex partners and needle/syringe sharing. We used multi-level logistic regression models, which incorporated sampling weights and random intercepts for city, to assess factors associated with these HIV risks, separately among men and women. The prevalence of HIV was significantly higher among women than men (53% vs 18.4%, p<0.01). Nearly 13% of men and 8% of women (p = .30) had multiple partners. Employment in men and relationship status and stigma in women were significantly associated with multiple partners. Approximately 25% of men and 19% of women engaged in needle sharing (p = .16). Younger age in women and depression symptoms in men were significantly associated with increased risk for sharing needles. We found that sexual and drug related risk behaviors were common among PWID in Northeast India, and there were differences between men and women in the socio-ecologic correlates of these behaviors. Contextually-integrated and gender-specific HIV prevention and intervention efforts are needed that consider factors at individual, interpersonal- and community-levels that uniquely impact HIV risks among PWID.

    A new species of lygosomatine scincid lizard is described from the sacred forests of Mawphlang, in Meghalaya, northeastern India. Sphenomorphus apalpebratus sp. nov. possesses a spectacle or brille, an unusual feature within the Scincidae, and a first for the paraphyletic genus Sphenomorphus. The new species is compared with other members of the genus to which it is here assigned, as well as to members of the lygosomatine genera Lipinia and Scincella from mainland India, the Andaman and Nicobar Islands, and southeast Asia, to which it also bears resemblance. The new taxon is diagnosable in exhibiting the following combination of characters: small body size (SVL to 42.0 mm); moveable eyelids absent; auricular opening scaleless, situated in a shallow depression; dorsal scales show a line of demarcation along posterior edge of ventral pes; midbody scale rows 27-28; longitudinal scale rows between parietals and base of tail 62-64; lamellae under toe IV 8-9; supraoculars five; supralabials 5-6; infralabials 4-5; subcaudals 92; and dorsum golden brown, except at dorsal margin of lateral line, which is lighter, with four faintly spotted lines, two along each side of vertebral row of scales, that extend to tail base. The new species differs from its congeners in the lack of moveable eyelids, a character shared with several distantly related scincid genera.

    Intestinal infection causing diarrheal disease is a dominant contributor to high morbidity and mortality in developing countries. This intervention study aimed to assess the response of specific anti-microbial and anti-retroviral therapy (ART) on enteropathogens identified in HIV/AIDS adult subjects from northern India. Seventy five ART naive (group 1) and seventy five ART adherent (group 2) HIV/AIDS adult subjects with diarrhea were enrolled. Stool samples from all subjects were examined for enteropathogens by wet mount, staining methods, culture and ELISA. Subjects with enteropathogens were started on specific therapy as per National AIDS Control Organisation, Government of India's guidelines. Follow-up stool samples were examined after 2-4 weeks of completion of therapy for persistence/clearing of enteropathogens. CD4+ T lymphocyte count was done for all subjects. At enrollment, group 1 had 26.13% bacterial, 57.66% parasitic & 16.22% fungal pathogens while group 2 had 11.9%, 69.05% & 19.05% pathogens, respectively. Parasitic diarrhea was more common than bacterial diarrhea. The coccidian parasites (Cryptosporidium spp. & Isospora belli) were the common parasites identified. Clearance of enteric pathogens was significant after specific anti-microbial therapy (p = 0.0001). Persistence of enteropathogens was seen primarily for coccidian parasites. Clearance of enteropathogens after specific therapy and the diagnostic yield of stool specimens were influenced by the CD4+ counts. Immune competence coupled with specific anti-microbial therapy displays the best response against enteric pathogens.

    The present study was undertaken for a period of two years from December 2010 to May 2012.Studying the benthos of Gulf of Kutch near shore waters is also useful in understanding changes in biological diversity of Gujarat coast. The use of benthos in aquatic ecological research is especially effective in assessing long term changes and detecting input from diffuse sources. The benthos reflects the effects organic enrichment by responding through detectable changes in population dynamics on a time scale of months to years. This is in contrast to plankton which shows a more immediate change to point sources with no long term consequences to the populations (Gray et al 1992). Benthoses were collected from 6 stations on regular basis and were identified. Altogether 60 species belonging to 39 families were identified and placed taxonomically during the course of investigation with sediment samples. Benthic environmental relationship species were observed and recorded. Our studies of monthly comparisons have become an interesting and popular approach in ecology and environmental relationships in the past a number of studies have been conducted on the ecology of macro benthic populations of Gulf of Kutch near shore. My research helps in Gulf of Kutch of the west coast of India has become an important economic asset of the country serving commercial navigation and the fishing sector with environmental relation of benthos in the Gulf of Kutch Gujarat.

    Northern regions of India experience severe fog conditions during the winter period (December-January) each year. In the present study, concurrent measurements of black carbon aerosols (BC), Carbon monoxide (CO), Surface Ozone (O 3) and oxides of Nitrgen (NO x) have been carried out in Allahabad, located in northern India in order to understand the impact on pollutant concentrations during fog periods. The results of the present study show higher concentrations of BC, NO x and CO during morning and late night hours in the study area. Diurnal variations of ozone concentrations varied from 14 ppbv to 35 ppbv and were observed to increase gradually after sunrise attaining a maximum value by evening time and to decrease gradually thereafter. Concentrations of BC, NO x, O 3 and CO were found to be very low during fog periods over the study area. BC showed a positive correlation with CO and a negative correlation with surface ozone concentrations. The slope between black carbon aerosols and ground level ozone suggests that every 1 μg m - 3 increase in black carbon aerosol mass concentration causes a reduction of 0.7 μg m - 3 surface ozone.

  8. Clockwise rotation of the Brahmaputra Valley relative to India: Tectonic convergence in the eastern Himalaya, Naga Hills, and Shillong Plateau

    GPS data reveal that the Brahmaputra Valley has broken from the Indian Plate and rotates clockwise relative to India about a point a few hundred kilometers west of the Shillong Plateau. The GPS velocity vectors define two distinct blocks separated by the Kopili fault upon which 2-3 mm/yr of dextral slip is observed: the Shillong block between longitudes 89 and 93°E rotating clockwise at 1.15°/Myr and the Assam block from 93.5°E to 97°E rotating at ≈1.13°/Myr. These two blocks are more than 120 km wide in a north-south sense, but they extend locally a similar distance beneath the Himalaya and Tibet. A result of these rotations is that convergence across the Himalaya east of Sikkim decreases in velocity eastward from 18 to ≈12 mm/yr and convergence between the Shillong Plateau and Bangladesh across the Dauki fault increases from 3 mm/yr in the west to >8 mm/yr in the east. This fast convergence rate is inconsistent with inferred geological uplift rates on the plateau (if a 45°N dip is assumed for the Dauki fault) unless clockwise rotation of the Shillong block has increased substantially in the past 4-8 Myr. Such acceleration is consistent with the reported recent slowing in the convergence rate across the Bhutan Himalaya. The current slip potential near Bhutan, based on present-day convergence rates and assuming no great earthquake since 1713 A.D., is now ~5.4 m, similar to the slip reported from alluvial terraces that offsets across the Main Himalayan Thrust and sufficient to sustain a Mw ≥ 8.0 earthquake in this area.

    North-east India, being a corridor to South-east Asia, is believed to play an important role in transmitting drug resistant Plasmodium falciparum malaria to India and South Asia. North-east India was the first place in India to record the emergence of drug resistance to chloroquine as well as sulphadoxine/pyrimethamine. Presently chloroquine resistance is widespread all over the North-east India and resistance to other anti-malarials is increasing. In this study both in vivo therapeutic efficacy and molecular assays were used to screen the spectrum of drug resistance to chloroquine and sulphadoxine/pyrimethamine in the circulating P. falciparum strains. A total of 220 P. falciparum positives subjects were enrolled in the study for therapeutic assessment of chloroquine and sulphadoxine/pyrimethamine and assessment of point mutations conferring resistances to these drugs were carried out by genotyping the isolates following standard methods. Overall clinical failures in sulphadoxine/pyrimethamine and chloroquine were found 12.6 and 69.5% respectively, while overall treatment failures recorded were 13.7 and 81.5% in the two arms. Nearly all (99.0%) the isolates had mutant pfcrt genotype (76T), while 68% had mutant pfmdr-1 genotype (86Y). Mutation in dhps 437 codon was the most prevalent one while dhfr codon 108 showed 100% mutation. A total of 23 unique haplotypes at the dhps locus and 7 at dhfr locus were found while dhps-dhfr combined loci revealed 49 unique haplotypes. Prevalence of double, triple and quadruple mutations were common while 1 haplotype was found with all five mutated codons (F/AGEGS/T) at dhps locus. Detection of quadruple mutants (51I/59R/108N/164L) in the present study, earlier recorded from Car Nicobar Island, India only, indicates the presence of high levels of resistance to sulphadoxine/pyrimethamine in north-east India.

    Background: Migration has been linked to the spread of HIV epidemic from the urban areas of western India to the rural areas of north India. Objectives: This is the first population-based study among the wives of migrant workers of Muzaffarpur district in Bihar with objectives to describe their sexual behavior within marriage, estimate the prevalence of HIV, and to know their awareness regarding HIV/AIDS. Methods: A two-stage cluster survey was conducted by randomly selecting 25 eligible wives from each of the 34 selected villages. A total of 850 wives were interviewed and the blood samples were collected for HIV testing. To determine the factors associated with HIV/AIDS-awareness, we calculated adjusted odds ratios and 95% confidence intervals (CI) using multiple logistic regression analysis. Results: 34 (3%) of 850 wives reported condom use with their husband. HIV prevalence was 0.59% (95% CI: 0.19-1.37%) among the wives of migrant workers. Out of 850 wives, 132 (15.5%) had heard about HIV. Condoms use (OR = 3.21, 95% CI: 1.22-7.90) and premarital sex (OR=7.44, 95% CI: 1.6-33.67) were found significantly positively associated with HIV knowledge of wives. HIV awareness of the wives was significantly associated with age-group 15-24 years, literacy status, and possession of television and husbands’ literacy status. The knowledge about HIV among wives had significant positive impact on condoms use and premarital sex. HIV prevalence among the wives of migrant workers was higher than the prevalence among women in the general population. Education was found to be positively associated with awareness about HIV. Conclusions: Effective interventions are needed for increasing awareness of HIV among wives of migrant workers in Bihar. PMID:28331250

    Giardia duodenalis, Cryptosporidium spp., and Entamoeba spp. are intestinal protozoa capable of infecting a range of host species, and are important causes of human morbidity and mortality. Understanding their epidemiology is important, both for public health and for the health of the animals they infect. This study investigated the occurrence of these protozoans in rhesus macaques (Macaca mulatta) in India, with the aim of providing preliminary information on the potential for transmission of these pathogens between macaques and humans. Faecal samples (n = 170) were collected from rhesus macaques from four districts of North-West India. Samples were analysed for Giardia/Cryptosporidium using a commercially available direct immunofluorescent antibody test after purification via immunomagnetic separation. Positive samples were characterised by sequencing of PCR products. Occurrence of Entamoeba was investigated first by using a genus-specific PCR, and positive samples further investigated via species-specific PCRs for Entamoeba coli, Entamoeba histolytica, Entamoeba dispar and Entamoeba moshkovskii. Giardia cysts were found in 31% of macaque samples, with all isolates belonging to Assemblage B. Cryptosporidium oocysts were found in 1 sample, however this sample did not result in amplification by PCR. Entamoeba spp. were found in 79% of samples, 49% of which were positive for E. coli. Multiplex PCR for E. histolytica, E. dispar and E. moshkovskii, did not result in amplification in any of the samples. Thus in 51% of the samples positive at the genus specific PCR, the Entamoeba species was not identified. This study provides baseline information on the potential for transmission of these zoonotic parasites at the wildlife-human interface.

    Background A multiple-strategy community intervention, known as National Rural Health Mission (NRHM), launched in India to improve the availability of and access to better-quality healthcare, especially for rural, poor mothers and children. The final goal of the intervention is to reduce maternal and child health inequalities across geographical areas, socioeconomic status groups, and sex of the child. Extensive, in-depth research is necessary to assess the effectiveness of NRHM, on multiple outcome dimensions. This paper presents the design of a new study, able to overcome the shortcomings of previous research. Objective To propose a comprehensive, methodologically sound protocol to assess the extent of implementation and the effectiveness of NRHM measures to improve maternal and child health outcomes and reduce maternal and child health inequalities. Design A mixed-methods approach (quantitative and qualitative) is proposed for this study in Haryana, a state in North India. NRHM's health sector plans included health system strengthening, specific maternal and child healthcare strategies, and communitization. Mission documents and reports on progress, financial monitoring, and common and joint review will be reviewed in-depth to assess the extent of the implementation of plans. Data on maternal and child health indicators will be obtained from demographic health surveys held before, during, and after the implementation of the first phase of the NRHM (2005–2012) and compared over time. Differences in maternal and child health indicators will be used to measure maternal and child health inequalities; these will be compared pre- and post-NRHM. Focus group discussions (FGDs) with service providers and in-depth interviews with program managers, community representatives, and mothers will be conducted until data saturation is achieved, in two districts of Haryana. Using Nvivo software, an inductive qualitative content analysis will be performed to search for the

    The prevalence of overweight/obesity is increasing worldwide. Although countries like India are typically thought of as having a high prevalence of undernutrition, significant proportions of overweight/obese now co-exist with the undernourished. This study aims to find the prevalence of overweight/obesity, and its association with socioeconomic change, among Tangkhul women in India. The cross-sectional study was carried out among 346 Tangkhul women aged 20-70 years, who were divided into five 10-year age groups. Mean BMI was found to be lowest among the youngest age group, and it increased with age until the age of 59 and then declined. The prevalence of overweight and obesity was found to be 27.1%, as assessed from the Asian cut-off point. Although the prevalence of obesity (2.0%) was low when compared with Indian non-tribal female populations, the prevalence of overweight (25.1%) was not far behind. Overweight and obesity were found to be associated with age, marital status, physical activity level, lifestyle and improvement in socioeconomic status, especially occupation and income. When compared with urban non-tribal Indian females, who have a higher socioeconomic status, the prevalence of overweight/obesity among Tangkhul females is lower, indicating its association with socioeconomic status. Tangkhul Naga is a population where the majority are believed to be thin traditionally owing to the difficult hilly terrain and their physically active lifestyle. With urbanization and economic development, nutritional transition, improved socioeconomic status and an increasingly sedentary lifestyle have been observed, which have contributed to the increasing prevalence of overweight/obesity among Tangkhul Naga women.

    North Eastern Region (NER) of India comprising of eight states considered to be most unique and one of the most challenging regions to govern due to its unique physiographic condition, rich biodiversity, disaster prone and diverse socio-economic characteristics. Operational Remote Sensing services increased manifolds in the region with the establishment of North Eastern Space Applications Centre (NESAC) in the year 2000. Since inception, NESAC has been providing remote sensing services in generating inventory, planning and developmental activities, and management of natural resources, disasters and dissemination of information and services through geo-web services for NER. The operational remote sensing services provided by NESAC can be broadly divided into three categories viz. natural resource planning and developmental services, disaster risk reduction and early warning services and information dissemination through geo-portal services. As a apart of natural resources planning and developmental services NESAC supports the state forest departments in preparing the forest working plans by providing geospatial inputs covering entire NER, identifying the suitable culturable wastelands for cultivation of silkworm food plants, mapping of natural resources such as land use/land cover, wastelands, land degradation etc. on temporal basis. In the area of disaster risk reduction, NESAC has initiated operational services for early warning and post disaster assessment inputs for flood early warning system (FLEWS) using satellite remote sensing, numerical weather prediction, hydrological modeling etc.; forest fire alert system with actionable attribute information; Japanese Encephalitis Early Warning System (JEWS) based on mosquito vector abundance, pig population and historical disease intensity and agriculture drought monitoring for the region. The large volumes of geo-spatial databases generated as part of operational services are made available to the administrators and

    The North Almora Thrust zone (NATZ) marks the boundary of the Almora Crystalline Complex (ACC) against the Lesser Himalayan Sedimentary sequence (LHS) in the north. Its southern counterpart, the South Almora Thrust (SAT), is a sharply marked contact between the ACC and the LHS in the south. Published studies argue various contradictory emplacement modes of the North Almora Thrust. Recent studies have implied splays of smaller back thrusts in the NATZ. The present study investigates meso- and microstructures, and strain distribution in the NATZ and compares it with strain distribution across the SAT. In the NATZ, field evidence reveals repeated sequence of 10-500 m thick slices of proto- to ultra-mylonite, thrust over the Lesser Himalayan Rautgara quartzite. In accordance with the field evidence, the strain analysis reveals effects of splays of smaller thrust in the NATZ. The study therefore, argues that contrary to popular nomenclature the northern contact of the ACC with the LHS is not a single thrust plane, but a thrust zone marked by numerous thrust splays.

    Comparative data regarding the distribution of non-Hodgkin lymphoma (NHL) subtypes in North Africa, the Middle East and India (NAF/ME/IN) is scarce in the literature. In this study, we evaluated the relative frequencies of NHL subtypes in this region. Five expert haematopathologists classified 971 consecutive cases of newly-diagnosed NHL from five countries in NAF/ME/IN. After review, 890 cases (91·7%) were confirmed to be NHL and compared to 399 cases from North America (NA). The male-to-female ratio was significantly higher in NAF/ME/IN (1·8) compared to NA (1·1; P< 0·05). The median ages of patients with low-grade (LG) and high-grade (HG) B-NHL in NAF/ME/IN (56 and 52 years, respectively) were significantly lower than in NA (64 and 68 years, respectively). In NAF/ME/IN, a significantly lower proportion of LG B-NHL (28·4%) and a higher proportion of HG B-NHL (58·4%) were found compared to NA (56·1% and 34·3%, respectively). Diffuse large B-cell lymphoma was more common in NAF/ME/IN (49·4%) compared to NA (29·3%), whereas follicular lymphoma was less common in NAF/ME/IN (12·4%) than in NA (33·6%). In conclusion, we found significant differences in NHL subtypes and clinical features between NAF/ME/IN and NA. Epidemiological studies are needed to better understand the pathobiology of these differences.

    Objective A rapid survey was carried out in Shaheed Bhagat Singh Nagar District of Punjab state in India to ascertain health seeking behavior and out-of-pocket health expenditures. Methods Using multistage cluster sampling design, 1,008 households (28 clusters x 36 households in each cluster) were selected proportionately from urban and rural areas. Households were selected through a house-to-house survey during April and May 2014 whose members had (a) experienced illness in the past 30 days, (b) had illness lasting longer than 30 days, (c) were hospitalized in the past 365 days, or (d) had women who were currently pregnant or experienced childbirth in the past two years. In these selected households, trained investigators, using a tablet computer-based structured questionnaire, enquired about the socio-demographics, nature of illness, source of healthcare, and healthcare and household expenditure. The data was transmitted daily to a central server using wireless communication network. Mean healthcare expenditures were computed for various health conditions. Catastrophic healthcare expenditure was defined as more than 10% of the total annual household expenditure on healthcare. Chi square test for trend was used to compare catastrophic expenditures on hospitalization between households classified into expenditure quartiles. Results The mean monthly household expenditure was 15,029 Indian Rupees (USD 188.2). Nearly 14.2% of the household expenditure was on healthcare. Fever, respiratory tract diseases, gastrointestinal diseases were the common acute illnesses, while heart disease, diabetes mellitus, and respiratory diseases were the more common chronic diseases. Hospitalizations were mainly due to cardiovascular diseases, gastrointestinal problems, and accidents. Only 17%, 18%, 20% and 31% of the healthcare for acute illnesses, chronic illnesses, hospitalizations and childbirth was sought in the government health facilities.

    Melocanna baccifera (Roxb.) Kurz is an economically important bamboo of North-East India experiencing population depletion in its natural habitats. Genetic variation studies were conducted in 7 populations sampled from 5 districts of Manipur using ISSR molecular markers. The investigation was carried out as a primary step towards developing effective conservation strategies for the protection of bamboo germplasm. ISSR marker analysis showed significant level of genetic variation within the populations as revealed by moderately high average values of Nei's genetic diversity (H 0.1639), Shannon's diversity index (I 0.2563), percentage of polymorphic bands (PPB 59.18), total genetic variation (Ht 0.1961), and genetic diversity within population (Hs 0.1639). The study also divulged a high genetic variation at species level with Shannon's diversity index (I), Nei's genetic diversity (H), and percentage of polymorphic band (PPB%) recorded at 0.3218, 0.1939, and 88.37, respectively. Genetic differentiation among the populations (Gst) was merely 19.42% leaving 80.58% of genetic variation exhibited within the populations. The low genetic diversity between populations was consistent with AMOVA. The low genetic differentiation among populations coupled with existence of significantly high genetic diversity at species level indicated the urgent necessity of preserving and protecting all the existing natural bamboo populations in the region.

    Background: Oral cancer is one of the most common life-threatening diseases all over the world. Developing countries face several challenges to identify and remove potential risk factors. Chewing tobacco/pan masala is considered to be the most potent risk factor for oral precancerous lesions and oral cancer. Objectives: To investigate the relative occurrence of different oral pre-cancerous lesions and oral cancer in North India and to identify the associated risk factors. Materials and Methods: A hospital-based study was conducted and 471 subjects were recruited in the study. The subjects comprised patients with squamous cell carcinoma (n = 85), oral submucous fibrosis (n = 240), leukoplakia (n = 32), lichen planus (n = 15), and controls (n = 99). Statistical analysis of the data was done using Chi-square and regression analysis. Results: A strong correlation was observed between the presence of the chewing habit in all the oral precancerous lesions and oral cancer. Duration of the habit and intensity of habit ware also strongly correlated with the risk of oral precancerous lesions and oral cancer. Other factors such as alcohol and smoking were found to be less important in concern with oral cancer and precancerous lesions. PMID:25937723

    Uranium (U)-tolerant aerobic chemo-heterotrophic bacteria were isolated from the sub-surface soils of U-rich deposits in Domiasiat, North East India. The bacterial community explored at molecular level by amplified ribosomal DNA restriction analysis (ARDRA) resulted in 51 distinct phylotypes. Bacterial community assemblages at the U mining site with the concentration of U ranging from 20 to 100 ppm, were found to be most diverse. Representative bacteria analysed by 16S rRNA gene sequencing were affiliated to Firmicutes (51%), Gammaproteobacteria (26%), Actinobacteria (11%), Bacteroidetes (10%) and Betaproteobacteria (2%). Representative strains removed more than 90% and 53% of U from 100 μM and 2 mM uranyl nitrate solutions, respectively, at pH 3.5 within 10 min of exposure and the activity was retained until 24 h. Overall, 76% of characterized isolates possessed phosphatase enzyme and 53% had PIB-type ATPase genes. This study generated baseline information on the diverse indigenous U-tolerant bacteria which could serve as an indicator to estimate the environmental impact expected to be caused by mining in the future. Also, these natural isolates efficient in uranium binding and harbouring phosphatase enzyme and metal-transporting genes could possibly play a vital role in the bioremediation of metal-/radionuclide-contaminated environments.

    Background. Hypertension is a leading cause of morbidity and mortality worldwide. We aimed to evaluate the prevalence of hypertension in a population of male bus drivers in North Kerala, India. Methods. The study population included male bus drivers of Corporation Bus stand Kozhikode, Kerala. Blood pressure, height, and weight of subjects were measured, and relevance was obtained using a structured questionnaire. Results. Age varied from 21 to 60 years (mean 36.5 ± 8.4). Among 179 bus drivers studied, 16.8% (30/179) had normal BP, 41.9% (75/179) had prehypertension, and 41.3% (74/179) had hypertension. Isolated systolic HTN was seen in 6.70% (12/179) individuals. Out of 74 hypertensives, 9 (12.1%) were aware of their hypertension, while 3 (4.0%) were medicated and only 1 (1.3%) had BP adequately controlled. Age > 35 years (P = 0.015), BMI ≥ 23 kg/m(2) (P = 0.007), supporting more than four family members (P = 0.011), and taking main meals from restaurants on most working days (P = 0.017) were independently associated with HTN in binary logistic regression. Conclusion. Prevalence of hypertension was high among bus drivers. Age > 35 years, elevated BMI, supporting a large family, and dietary habits associated with the job showed significant association with hypertension. Primary and secondary prevention strategies need to be emphasized in this occupational group.

    Intramuscular injections can provoke muscular paralysis especially, if the child has had exposure to polio virus. The purpose of the study was to determine the association with known risk factors for motor disabilities in two remote villages of North Karnataka (India), where an increased number of disabled people among select communities had been reported. A community based survey was conducted. The selection of study subjects was done through screening, history related with occurrence of musculoskeletal disability, screening and general examination of the affected joints and muscles. Data analysis was done by estimation of percentages. Among the physical disabilities identified, the most common was post-polio residual paralysis. 35.65% (n = 41) subjects had developed paralysis following the administration of an intramuscular injection when they had acute viremia in childhood, indicating that (probably) muscle paralysis would have been provoked by intramuscular injections, resulting in provocative poliomyelitis. Unnecessary injection must be avoided in children during acute viremia state and use of oral polio vaccine should be encouraged.

    The study described here is based on the measurements of soil gas radon-thoron concentrations performed at Dharamsala region of north-west (NW) Himalayas, India. The study area is tectonically and environmentally significant and shows the features of ductile shear zone due to the presence of distinct thrust planes. Solid state nuclear track detectors (LR-115 films) have been used for the soil gas radon-thoron monitoring. Twenty five radon-thoron discriminators with LR-115 films were installed in the borehole of about 50 cm in the study areas. The recorded radon concentration varies from 1593 to 13570 Bq/m3 with an average value of 5292 Bq/m3. The recorded thoron concentration varies from 223 to 2920 Bq/m3 with an average value of 901 Bq/m3. The anomalous value of radon-thoron has been observed near to the faults like main boundary thrust (MBT and MBT2) as well as neotectonic lineaments in the region.

    Genotoxicity is one of the important endpoints for risk assessment of various lifestyle factors. The study is the first report on the genotoxic effect associated with sadagura, a unique smokeless tobacco prepared in southern Assam province of North-East India. Sadagura is consumed with or without betel quid and/or smoking. In the present cytogenetic monitoring study, analysis of micronuceus (MN), nuclear bud, binucleated, karyorrhectic, karyolytic and pyknotic cells tests were performed in the exfoliated buccal cells of 75 habituates and compared to controls matched for gender, age, and habit. Significant increase in the frequency of MN was found in sadagura chewers (0.48%, P < 0.001), smokers (0.46%, P < 0.01), betel quid with sadagura chewers (0.91%, P < 0.001) and smokers chewing betel quid with sadagura (0.53%, P < 0.001) as compared to the unexposed control group (0.07%). Betel quid chewers showed significant increase (1.65%, P < 0.05) in the frequency of binucleated cells as compared to the control group (0.16%). Results of this study demonstrated that sadagura consumed as a single agent or in combination with betel quid, leads to a significant induction of cytogenetic damage in the buccal epithelial cells of habituates. We suggest that analysis of other degenerative nuclear changes in addition to MN can provide valuable information while evaluating potential genotoxic agents.

    A viable option for increasing nitrogen (N) use efficiency and mitigation of negative impacts of N on the environment is to capitalize on multi-element interactions through implementation of nutrient management programs that provide balanced nutrition. Numerous studies have demonstrated the immediate efficacy of this approach in the developing regions like China and India as well as developed countries in North America. Based on 241 site-years of experiments in these countries, the first-year N recovery efficiency (RE) for the conventional or check treatments averaged 21% while the balanced treatments averaged 54% RE, for an average increase of 33% in RE due to balanced nutrition. Effective policies to promote adoption are most likely those that enable site-specific approaches to nutrient management decisions rather than sweeping, nation-wide incentives supporting one nutrient over another. Local farmers, advisers and officials need to be empowered with tools and information to help them define necessary changes in practices to create more balanced nutrient management.

    The northernmost exposures of sub-Himalayan Cenozoic strata in the Hazara-Kashmir syntaxial region of north Pakistan comprises the Paleocene-Eocene marine strata in the lower part and Oligocene-Miocene nonmarine strata in the upper part. This study provides the detrital zircon U-Pb geochronology of the Cenozoic strata in this area. The strong resemblance of U-Pb age spectra of Paleocene Hangu, Lockhart and Patala formations with those of Himalayan strata indicate an Indian plate provenance. The first appearance of <100 Ma detrital zircon U-Pb ages within the lower most part of the Early Eocene Margalla Hill Limestone indicates a shift from an Indian to Asian provenance. Geologic mapping shows the existence of a disconformity between the lower and upper most part of the Patala Formation, which is interpreted to have been formed by the migration of a flexural forebulge through this region. We consider the upper most part of the Patala Formation to have been deposited within the distal foredeep of the foreland basin. The Indian to Asian provenance shift and the presence of a possible foreland basin forebulge provide strong evidence that India-Asia collision was underway in northern Pakistan at ca. 56-55 Ma.

    The study of ethnobotany relating to any tribe is in itself a very intricate or convoluted process. This paper documents the traditional knowledge of medicinal plants that are in use by the indigenous Jaintia tribes residing in few isolated pockets of northeast India. The present study was done through structured questionnaires in consultations with the tribal practitioners and has resulted in the documentation of 39 medicinal plant species belonging to 27 families and 35 genera. For curing diverse form of ailments, the use of aboveground plant parts was higher (76.59%) than the underground plant parts (23.41%). Of the aboveground plant parts, leaf was used in the majority of cases (23 species), followed by fruit (4). Different underground plant forms such as root, tuber, rhizome, bulb and pseudo-bulb were also found to be in use by the Jaintia tribe as a medicine. Altogether, 30 types of ailments have been reported to be cured by using these 39 medicinal plant species. The study thus underlines the potentials of the ethnobotanical research and the need for the documentation of traditional ecological knowledge pertaining to the medicinal plant utilization for the greater benefit of mankind.

    Numerous studies show that exposure to entertainment-education-based mass media campaigns is associated with reduction in risk behaviors. Concurrently, there is a growing interest in comparing the cost-effectiveness of HIV prevention interventions taking into account infrastructural and programmatic costs. In such analyses, though few in number, mass media campaigns have fared well. Using data from a mass media communication campaign in the low HIV prevalence states of Uttar Pradesh, Rajasthan, and Delhi in Northern India, in this article we examine the following: (1) factors that mediate behavior change in different components of the campaign, comprising a TV drama, reality show for youth audiences, and TV spots; (2) the relative impact of campaign components on the behavioral outcome: condom use; and (3) the cost-effectiveness calculations arising from this analysis. Results suggest that recall of the TV spots and the TV drama influences behavior change and is strongly associated with interpersonal communication and positive gender attitudes. The TV drama, in spite of being the costliest, emerges as the most cost-effective component when considering the behavioral outcome of interest. The analysis of the comparative cost-effectiveness of individual campaign components provides insights into the planning of resources for communication interventions globally.

    Background: Delhi, the capital of India, has suffered many outbreaks of dengue in recent past and despite the obvious magnitude of problem, very scarce evidence exists that documents the knowledge, awareness and practices of the people regarding dengue. Aim: To assess the knowledge and practices related to control of dengue fever and to assess the differences in knowledge and practices based on sex and literacy. Materials and Methods: A cross-sectional study was conducted among persons visiting a tertiary care hospital in New Delhi. A systematic sampling procedure was adopted and a pretested questionnaire was used. Results: A total of 215 individuals were interviewed. Majority of the respondents (96.3%) had heard about dengue. The important sources of information were television (54.9%) and newspaper/magazines (51.7%). Around 89% of the study participants considered dengue as “serious problem”. Nearly 86% participants were aware of the spread of dengue by mosquitoes while 73% were aware of one of the correct breeding sites of Aedes mosquito. Mosquito mats/liquidators were used by 61% of respondents, coils by 56% and repellant creams by 22%. Conclusion: The awareness regarding dengue and mosquito control measures was satisfactory to an extent. Programs should focus that this knowledge gets translated into practice. PMID:22754880

    In the global climate change scenario, application of biochar in soil has become one of the important management practices for carbon sequestration, soil health improvement and climate change mitigation. In this study, an attempt was made to see the effect of biochar prepared from weed biomass on soil properties in subtropical northeast India. Biochar were prepared from seven locally available weed biomass viz. Ageratum conyzoides, Lantana camera, Gynura sp., Setaria sp., Avena fatua, Maize stalk, Pine needles and were characterised. Apot experiment was conducted with maize, where biochar was applied alone and in combination with fertilizers. Results revealed that biochar had significant impact on soil pH, SOC, and available nutrients like N, P and K. It also had significant impact on maize biomass yield. All biochar contained more than 50% stable carbon. Increase in soil pH was in the range of 0.26 to 0.3 and that of SOC from 1.62% in control to 1.74% in biochar added treatments. Biochars alone improved the available nitrogen ranging from 4.5 to 21.3 mg kg(-1), available P from 3.32 to 3.68 mg kg(-1) and increased K content by 20% above control. Weed biomass can be potential alternative to enhance soil and crop productivity through conversion into biochar.

    Iron deficiency anemia is the most frequent micronutrient deficiency in the developing countries like India especially affecting pregnant women and young children. Iron is an essential element involved in myelin formation, neurotransmitter synthesis and neuro-metabolism. Several behavioural disturbances have been reported in iron deficient children. In the present study, we determined the prevalence of iron deficiency anemia in children with behavioural disorders and assessed the improvement in terms of symptoms (by child behaviour check list), haematological parameters and iron status after treatment with oral iron. In this prospective study, 44 children in the age group of 3-12 years who were diagnosed with behavioural disorders were evaluated. Complete blood counts using automated hematology analyzer and iron parameters (serum iron, total iron binding capacity, % transferrin saturation and serum ferritin) were measured in all the patients to assess the prevalence of iron deficiency in these children. Thirty age matched controls were also studied. Iron deficiency was found in 32 (73%) children, as assessed by transferrin saturation <16% and/or serum ferritin <16 μg/l. Following treatment with iron for 100 ± 10 days, there was a statistically (P ≤ 0.05) significant improvement in the clinical features, haematological profile and iron status. The presence of iron deficiency in children with behavioural disorders and subsequent improvement in clinical features, haematological profile and iron status suggests a possible causal relationship between iron deficiency and behavioural disorders.

    A modified DRASTIC model in a geographic information system (GIS) environment coupled with an information-analytic technique called `rough sets' is used to understand the aquifer vulnerability characteristics of a segment of the lower Kali watershed in western Uttar Pradesh, India. Since the region is a flat plain, topography (T) is removed as a potential control. Other parameters are the same as in DRASTIC, hence the new model is termed as DRASIC. The rough set technique is employed to provide insight into the relative vulnerabilities of different administrative units (blocks) within the study area. Using rough sets, three important factors are computed: strength, certainty and coverage. Strength indicates how the vulnerability characteristics vary in the entire area, certainty gives the relative fractions of low, medium and high vulnerability regions within a particular block, and coverage computes the percentage of a particular vulnerability state in each block. The purpose of the work is to demonstrate the utility of this integrated approach in classifying different administrative blocks in the study area according to their aquifer vulnerability characteristics. This approach is particularly useful for block-level planning and decision making for sustainable management of groundwater resources.

    Introduction Oral squamous cell carcinoma (OSCC) ranks 12th most common cancer in the world. Objective The aim of this study was to retrospectively evaluate the OSCC. Methods A retrospective study of 611 OSCC patients from January 2010 to December 2013 was carried out in Department of Surgical Oncology, King George's Medical University, Lucknow, India. Details of patient's sex, age, tobacco habit and site of cancer were noted. Data were analyzed by Student's t test and chi-squire (χ2) test. Results The prevalence of OSCC was significantly (p < 0.001) higher in males (75.9%) than females (24.1%). The mean age of female patients was higher than males (p < 0.001). In both the genders, the buccal mucosa and gingivobuccal sulcus were found to be the most affected sites. Moreover, the smokeless form of tobacco was found to be significantly associated with OSCC, especially in females. Conclusion The study concluded that OSCC is more common in men as compared to women, probably due to habit of tobacco consumption. Smokeless tobacco use is an important risk factor, especially in females. PMID:26937366

    Blood pressure readings were collected from 1042 adult females of rural and urban Jat Sikh community of Punjab, a north Indian State. Anthropometric measurements like height, weight and skinfold thickness were also collected. The difference between rural and urban females in systolic, diastolic and mean arterial blood pressure was found to be statistically significant. All anthropometric variables and age have a significant positive association with blood pressure. The effects of anthropometric variables on blood pressure were assessed simultaneously through stepwise multiple regression analysis. All 'F' ratios have been found highly significant (p < 0.001) among both rural and urban female population.

    We examine the conditions and processes of growth and preservation of multiaged monazite in micaceous matrix and in garnet porphyroblasts in staurolite-kyanite mica schists hosted in a hitherto-undiscovered shear zone that limits the northern extent of the Western Dharwar Craton (WDC), India. Garnet in the footwall schists grew during mid-crustal (600 ± 40 °C, 7.3 ± 1.2 kbar) loading and cooling as a consequence of the northward transport of the WDC lithologies. U-Th-Pb (total) ages in monazites in the matrix and in post-tectonic garnets yield well-defined peaks at 2.5, 2.2 and 1.9 Ga. In garnet, 2.5 and 2.2 Ga monazite grains, and 2.2 Ga monazites with 2.5 Ga cores are commonly occluded, but monazites with 1.9 Ga mantles around older cores are rare. By contrast, in the matrix, 1.9 Ga monazite grains and monazite with 1.9 Ga mantles around older cores are prominent, but the peak age frequencies of the two older populations are significantly lower than for monazites hosted as inclusions in garnet. Both in the matrix and garnet, the low-Th, high-Y domains in monazites yield the two older peak ages, while the 1.9 Ga ages correspond to the high-Th, low-Y domains. The preponderance of older ages in monazite hosted as inclusions in garnet relative to matrix monazites is because garnets formed between 2.2 and 1.9 Ga shielded the older monazites from dissolution-precipitation at 1.9 Ga. A few 1.9 Ga monazites hosted as inclusions in the garnet rims suggest renewed garnet growth at post-1.9 Ga. Multiple Pb-Pb age populations (2.5, 2.25, 2.1 and 1.8 Ga) in detrital zircon in the Sahanataha Group north of the Paleoarchean Antongil-Masora block (NE Madagascar) are identical to the multiple monazites ages north of the WDC, inferred to share a similar history and to be contiguous with the Antongil-Masora block in pre-Jurassic reconstructions of the Gondwanaland. We suggest the newly discovered Paleoproterozoic tectonic zone continued westward into Madagascar north of the

    A study was conducted on the chemical characterization of fine mode aerosol or PM2.5 over a rural atmosphere near the coast of Bay of Bengal in eastern India. Samples were collected and analyzed during March 2013 - February 2014. The concentration of PM2.5 was found span over a wide range from as low as 3 µg m-3 to as high as 180 µg m-3. The average concentration of PM2.5 was 62 µg m-3. Maximum accumulation of fine mode aerosol was observed during winter whereas minimum was observed during monsoon. Water soluble ionic species of fine mode aerosol were characterized over this rural atmosphere. In spite of being situated near the coast of Bay of Bengal, we observed significantly higher concentrations for anthropogenic species like ammonium and sulphate. The concentrations of these two species were much higher than the sea-salt aerosols. Ammonium and sulphate contributed around 30 % to the total fine mode aerosols. Even dust aerosol species like calcium also showed higher concentrations. Chloride to sodium ratio was found to be much less than that in standard sea-water indicating strong interaction between sea-salt and anthropogenic aerosols. Use of fertilizers in various crop fields and human and animal wastes significantly increased ammonium in fine mode aerosols. Dust aerosol species were accumulated in the atmosphere which could be due to transport of finer dust species from nearby metropolis or locally generated. Non-sea-sulphate and nitrate showed significant contributions in fine mode aerosols having both local and transported sources. Source apportionment shows prominent emission sources of anthropogenic aerosols from local anthropogenic activities and transported from nearby Kolkata metropolis as well.

    Arunachal Pradesh, the easternmost part of India, is endowed with diverse natural resources and inhabited by a variety of ethnic groups that have developed skills to exploit the biotic resources of the region for food and medicines. Information on animals and animal parts as components of folk remedies used by local healers and village headmen of the Nyishi and Galo tribes in their respective West Siang and Subansiri districts were obtained through interviews and structured questionnaires. Of a total of 36 vertebrate species used in treatments of ailments and diseases, mammals comprised 50%; they were followed by birds (22%), fishes (17%), reptiles (8%) and amphibians (3%). Approximately 20 common complaints of humans as well as foot and mouth disease of cattle were targets of zootherapies. Most commonly treated were fevers, body aches and pains, tuberculosis, malaria, wounds and burns, typhoid, smallpox, dysentery and diarrhoea, jaundice, and early pregnancy pains. Very few domestic animal species (e.g., goat and cattle) were used zootherapeutically. More frequently it was wild animals, including endangered or protective species like hornbill, pangolin, clouded leopard, tiger, bear, and wolf, whose various parts were either used in folk remedies or as food. Some of the animal-based traditional medicines or animal parts were sold at local markets, where they had to compete with modern, western pharmaceuticals. To record, document, analyze and test the animal-derived local medicines before they become replaced by western products is one challenge; to protect the already dwindling populations of certain wild animal species used as a resource for the traditional animal-derived remedies, is another.

    HIV exposed children are vulnerable to developmental delay irrespective of their HIV status due to combined effect of risk factors like poverty, prenatal drug exposure, stress and chronic illness in family and malnutrition. This cohort study assessed the development of 50 HIV exposed children aged 6-18 months at a Pediatric Centre of Excellence in HIV care in India. The development was assessed using Development Assessment Scale for Indian Infants (DASII) at enrolment, 3 and 6 months later. The development quotient (DQ) scores and proportion of children with developmental delay (DQ ≤ 70) were compared among two sub-groups, HIV infected (HI) and HIV exposed uninfected (HEU) children. The various social and clinical factors affecting development were studied by univariate and multivariate analysis. Prevalence of developmental delay was 2.4% in the HEU (n = 41), and 33.3% in HI (n = 9). The DQ of HI was significantly lower than that of HEU at all three assessments. The DQ of HI were also significantly lower compared to the HEU at ages 12.1-18 months (83.37 ± 20.73 vs 94.68 ± 5.13, p = 0.005) and 18.1-24 months (84.55 ± 15.35 vs 94.63 ± 5.86, p = 0.006) respectively. The development of HEU was adversely affected by lower socioeconomic status and presence of wasting. In addition, development of HI was also adversely influenced by presence of stunting and opportunistic infections, advanced disease stage and shorter ART duration. We conclude that with optimum care, HEU can have a normal development, while a considerable proportion of HI may continue to have delayed development.

    Chikungunya fever is an emerging mosquito-borne disease caused by the infection with chikungunya virus (CHIKV). The CHIKV has been rarely detected in mosquito vectors from Northern India, since vector surveillance is an effective strategy in controlling and preventing CHIKV transmission. Thus, virological investigation for CHIKV among mosquitoes of Aedes (A.) species was carried out in the Lucknow district during March 2010 to October 2011. We collected adult mosquitoes from areas with CHIKV positive patients. The adult Aedes mosquito samples were pooled, homogenized, clarified and tested for CHIKV by nonstructural protein 1 (nsP1) gene based polymerase chain reaction (PCR). A total 91 mosquito pools comprising of adult A. aegypti and A. albopictus were tested for CHIKV. The partial envelope protein (E1) gene sequences of mosquito-borne CHIKV strains were analyzed for genotyping. Of 91 pools, 6 pools of A. aegypti; and 2 pools of A. albopictus mosquitoes were identified positive for CHIKV by PCR. The phylogenetic analysis revealed clustering of CHIKV strains in two sub-lineages within the monophyletic East-Central South African (ECSA) genotype. Novel amino acid changes at the positions 294 (P294L) and 295 (S295F) were observed during analysis of amino acid sequence of the partial E1 gene. This study demonstrates the genetic diversity of circulating CHIKV strains and reports the first detection of CHIKV strains in Aedes vector species from the state of Uttar Pradesh. These findings have implication for vector control strategies to mitigate vector population to prevent the likelihood of CHIKV epidemic in the near future.

    Arunachal Pradesh, the easternmost part of India, is endowed with diverse natural resources and inhabited by a variety of ethnic groups that have developed skills to exploit the biotic resources of the region for food and medicines. Information on animals and animal parts as components of folk remedies used by local healers and village headmen of the Nyishi and Galo tribes in their respective West Siang and Subansiri districts were obtained through interviews and structured questionnaires. Of a total of 36 vertebrate species used in treatments of ailments and diseases, mammals comprised 50%; they were followed by birds (22%), fishes (17%), reptiles (8%) and amphibians (3%). Approximately 20 common complaints of humans as well as foot and mouth disease of cattle were targets of zootherapies.

    Hemoglobinopathies are a group of inherited single-gene disorders found commonly in the Mediterranean region, Middle East, Indian subcontinent, Burma, and South East Asia. As many as 229 mutation variants of β-thalassemia are reported in the world, many community/region-specific mutations. Very little on thalassemia has been reported in Manipur, a North Eastern Indian state. Thus, a community genetic approach through population screening can be applied to the people of Manipur and a total of 602 blood samples from unrelated Meitei Brahmins (n=300) and Meitei Muslims (n=302) were screened for abnormal hemoglobins by Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT). HBA(2) level was estimated by using high-performance liquid chromatography and molecular analysis was done by using PCR. Sequencing was also carried out to confirm the mutations. High frequencies of NESTROFT positive (10%) and NESTROFT doubtful (11%) cases were found among the Meitei Brahmins in comparison to the Meitei Muslims [NESTROFT positive (3.31%) and NESTROFT doubtful (1.33%)]. The allele frequency of HB*E was 0.022 and 0.012 among the Meitei Brahmin and Meitei Muslim, respectively. Sequencing of the β-globin gene confirmed a very rare β-thalassemia [-90 C→T (0.33%)] among the Meitei Brahmins of Manipur. This mutation with hemoglobin E in one of the present population hints the presence of the Mongoloid stock among them, possibly from China. There is a need for further studies on other populations of Manipur and the neighboring North East Indian states using such genetic markers.

    Introduction Sepsis is the leading cause of mortality in non-coronary Intensive Care Units (ICUs). Oxidative stress is one of the important features in pathogenesis of sepsis. Aim This study was undertaken to evaluate levels of oxidants and antioxidants in patients with sepsis admitted to ICU. Study Design: This was a non-interventional clinical case-control study undertaken at a tertiary level teaching hospital in New Delhi, India. Materials and Methods Forty-six consecutive non-pediatric patients admitted to ICU with sepsis were included and subjected to detailed history, physical examination and investigations. Blood samples were drawn to evaluate oxidant Malondialdehyde (MDA) and antioxidant (alpha-tocopherol) levels. Acute Physiology and Chronic Health Evaluation II (APACHE II) and Organ Dysfunction and/or Infection (ODIN) scores were calculated and patients followed up for outcomes. Twenty age and sex matched healthy subjects served as controls. Results Mean levels of malondialdehyde were higher in patients than controls (17.2±3.8nm/ml versus 4.6±1.6nm/ml, p<0.001) while levels of alpha-tocopherol were lower (3.2±1.3μg/ml versus 9.9±2.0μg/ml, p<0.001). The mean APACHE II and ODIN scores were 18.1±9.3 and 1.7±1.3 respectively in patients. These scores were two to three fold higher in non survivor patients (n=22) in comparison with survivors (n=18) (p<0.001). There was no significant difference between the two groups in oxidants and antioxidants levels (p>0.05). However, a significant and positive correlation was observed between oxidant -antioxidant levels and APACHE II, ODIN and International Normalized Ratio (INR) scores in septic patients overall. Conclusion The oxidants in septic patients were significantly higher while antioxidants were significantly lower than healthy controls. There was also a significant correlation with APACHE II and ODIN scores. A large patient population based study may draw more specific conclusions. PMID:27656484

    The shape of the frontal part of the Himalaya around the north-eastern corner of the Kumaun Sub-Himalaya, along the Kali River valley, is defined by folded hanging wall rocks of the Himalayan Frontal Thrust (HFT). Two parallel faults (Kalaunia and Tanakpur faults) trace along the axial zone of the folded HFT. Between these faults, the hinge zone of this transverse fold is relatively straight and along these faults, the beds abruptly change their attitudes and their widths are tectonically attenuated across two hinge lines of fold. The area is constituted of various surfaces of coalescing fans and terraces. Fans comprise predominantly of sandstone clasts laid down by the steep-gradient streams originating from the Siwalik range. The alluvial fans are characterised by compound and superimposed fans with high relief, which are generated by the tectonic activities associated with the thrusting along the HFT. The truncated fan along the HFT has formed a 100 m high-escarpment running E-W for ˜5 km. Quaternary terrace deposits suggest two phases of tectonic uplift in the basal part of the hanging wall block of the HFT dipping towards the north. The first phase is represented by tilting of the terrace sediments by ˜30 ∘ towards the NW; while the second phase is evident from deformed structures in the terrace deposit comprising mainly of reverse faults, fault propagation folds, convolute laminations, flower structures and back thrust faults. The second phase produced ˜1.0 m offset of stratification of the terrace along a thrust fault. Tectonic escarpments are recognised across the splay thrust near south of the HFT trace. The south facing hill slopes exhibit numerous landslides along active channels incising the hanging wall rocks of the HFT. The study area shows weak seismicity. The major Moradabad Fault crosses near the study area. This transverse fault may have suppressed the seismicity in the Tanakpur area, and the movement along the Moradabad and Kasganj

    Pork occupies an important place in the diet of the population of Nagaland, one of the North East Indian states. We carried out a pilot study along the pork meat production chain, from live animal to end consumer. The goal was to obtain information about the presence of selected food borne hazards in pork in order to assess the risk deriving from these hazards to the health of the local consumers and make recommendations for improving food safety. A secondary objective was to evaluate the utility of risk-based approaches to food safety in an informal food system. We investigated samples from pigs and pork sourced at slaughter in urban and rural environments, and at retail, to assess a selection of food-borne hazards. In addition, consumer exposure was characterized using information about hygiene and practices related to handling and preparing pork. A qualitative hazard characterization, exposure assessment and hazard characterization for three representative hazards or hazard proxies, namely Enterobacteriaceae, T. solium cysticercosis and antibiotic residues, is presented. Several important potential food-borne pathogens are reported for the first time including Listeria spp. and Brucella suis. This descriptive pilot study is the first risk-based assessment of food safety in Nagaland. We also characterise possible interventions to be addressed by policy makers, and supply data to inform future risk assessments.

    Kedarnath is small town built around in important Hindu temple in the Rudraprayag district, Uttarakhand in northern India. Located at an elevation of 3,583 m, it is situated in a remote valley with no vehicular access. In summer, the temple is an important pilgrimage destination, with thousands of visitors per day, all of whom have to access the location via a 14 km trek or horse ride along a paved pathway, or via a helicopter ride. Between 14th and 17th June 2013, Uttarakhand was affected by unusually heavy early monsoonal rainfall. Whilst the rainfall totals did not reach record levels, the precipitation fell onto thawing snow, inducing very large debris flows. Kedarnath was affected by two major debris flows. According to eyewitness reports the first struck without warning in the evening of 16th June at about 7 pm local time. The second, larger, event occurred the following morning at about 6 am. The two debris flows destroyed most of the buildings in Kedarnath, although the temple survived with some damage. Across Uttarakhand it is estimated that about 5700 people died in the debris flows; the majority of these losses were at Kedarnath and in the immediate downstream communities. In the aftermath of the disaster there was considerable uncertainty as to the cause of the debris flows, with much speculation about the possibility that either a rock avalanche had developed on the flanks of the adjacent mountains or that there had been a catastrophic glacial collapse event upstream of the town. On 18th June the Indian Remote Sensing Organisation (IRSO) captured and released a RISAT-1 image of Kedarnath. Although the resolution was insufficient to determine what had occurred to trigger the disaster, it served to highlight two potential sources of the debris flows. One of these was an area of disturbance at the snout of the Charobari Glacier upslope from the town; the other was a possible landslide scar on an adjacent slope. On 23rd June 2013 NASA captured a Landsat 8

    The North Eastern part of India nestled between the Eastern Himalayas and the South East Asia mountains and valleys falls in the high risk seismic zone 5. Five major earthquakes (M>5) occurred from 2009 to 2013 within this zone. The epicentres of the earthquakes lied within about 2.5° in latitude and longitude from Dibrugarh (27.5° N, 94.9° E) where ionospheric TEC is being recorded using a NOVATEL GSV4004B receiver since 2009. The TEC data has been analyzed to examine the signature of these earthquakes on the ionosphere prior to their occurrence by removing the ionospheric anomalies that might be caused by variations in solar and magnetic activities. The inter-quartile range of TEC data is utilized to construct their upper and lower bounds to detect the excursions outsides the bounds which might be associated with impending earthquakes. The results indicate large enhancements and depletion in TEC on geomagnetically quite days at Dibrugarh, which is within the earthquake preparation zones. Both enhancement and depletion in TEC have been observed prior to 1 to 15 days of the earthquakes, mainly during daytime hours. The enhancement in TEC was seen before four major earthquakes respectively M 6.4, M 6.1, M 5.8 and M 5.4, while in contrast depletion in TEC was observed before the M 5.6 earthquake. Probable causes of these enhancement and depletion prior to the earthquakes are discussed. One probable cause could be the large increase in surface latent heat flux observed between 4-8 days prior to the earthquakes near the epicenter.

    Emission of smoke and aerosol from open field burning of crop residue is a long-standing subject matter of atmospheric pollution. In this study, we proposed a new approach of estimating fuel load in the fire pixels and corresponding emissions of selected GHGs and aerosols i.e. CO2, CO, NO2, SO2, and total particulate matter (TPM) due to burning of crop residue under rice and wheat cropping systems in Punjab in north-west India from 2002 to 2012. In contrasts to the conventional method that uses RPR ratio to estimate the biomass, fuel load in the fire pixels was estimated as a function of enhanced vegetation index (EVI). MODIS fire products were used to detect the fire pixels during harvesting seasons of rice and wheat. Based on the field measurements, fuel load in the fire pixels were modelled as a function of average EVI using second order polynomial regression. Average EVI for rice and wheat crops that were extracted through Fourier transformation were computed from MODIS time series 16 day EVI composites. About 23 % of net shown area (NSA) during rice and 11 % during wheat harvesting seasons are affected by field burning. The computed average fuel loads are 11.32 t/ha (±17.4) during rice and 10.89 t/ha (±8.7) during wheat harvesting seasons. Calculated average total emissions of CO2, CO, NO2, SO2 and TPM were 8108.41, 657.85, 8.10, 4.10, and 133.21 Gg during rice straw burning and 6896.85, 625.09, 1.42, 1.77, and 57.55 Gg during wheat burning. Comparison of estimated values shows better agreement with the previous concurrent estimations. The method, however, shows its efficiency parallel to the conventional method of estimation of fuel load and related pollutant emissions.

    Cloud characteristics over the rain-shadow region of the north central peninsular India has been studied using C-band radar data for the period 21 September-30 October 2011. The period covers withdrawal and post-withdrawal periods of monsoon 2011. Though the study has been carried out for one season, it has been shown that it is representative of climatic feature over the region. The cloud characteristics have been discussed in the context of large scale dynamical and thermodynamical conditions over the region using NCEP wind data and radiosonde data, respectively. The large scale dynamic and thermodynamical conditions were found favorable for occurrence of widespread and deep convection. The cloud top heights show tri-modal distribution with peaks at 2-3, 4-6 and 8-12 km which are associated with cumulus, congestus and cumulonimbus clouds, respectively. The tops of these three types of the clouds are found to be associated with the stable layers in the atmosphere. The frequency of congestus clouds was the highest. The cloud characteristics over the region differ from other tropical land and oceanic regions in respect of maximum height, mean duration and cumulative frequency distribution. Distribution of cloud top height and duration show deviation from lognormality in the lower ends. It indicates that the cloud growth mechanism is different than that observed over other tropical land and oceanic regions and also due to the large wind shear prevailed over the region. During the period, a large number of suitable clouds were found available for hygroscopic and glaciogenic cloud seeding.

    Consumer knowledge is understood to play a role in managing risk factors associated with cardiovascular disease and may be influenced by level of education. The association between population knowledge, behaviours and actual salt consumption was explored overall, and for more-educated compared to less-educated individuals. A cross-sectional survey was done in an age-and sex-stratified random sample of 1395 participants from urban and rural areas of North and South India. A single 24-h urine sample, participants’ physical measurements and questionnaire data were collected. The mean age of participants was 40 years, 47% were women and mean 24-h urinary salt excretion was 9.27 (8.87–9.69) g/day. Many participants reported favourable knowledge and behaviours to minimise risks related to salt. Several of these behaviours were associated with reduced salt intake—less use of salt while cooking, avoidance of snacks, namkeens, and avoidance of pickles (all p < 0.003). Mean salt intake was comparable in more-educated (9.21, 8.55–9.87 g/day) versus less-educated (9.34, 8.57–10.12 g/day) individuals (p = 0.82). There was no substantively different pattern of knowledge and behaviours between more-versus less-educated groups and no clear evidence that level of education influenced salt intake. Several consumer behaviours related to use of salt during food preparation and consumption of salty products were related to actual salt consumption and therefore appear to offer an opportunity for intervention. These would be a reasonable focus for a government-led education campaign targeting salt. PMID:28212309

    Northeast India (NEI) is located within the boundary of the great Himalayas in the north and the Bay of Bengal (BoB) in the southwest, experiences the mixed influence of the westerly dust advection from the Indian desert, anthropogenic aerosols from the highly polluted Indo-Gangetic Plains (IGP) and marine aerosols from BoB. The present study deals with the estimation and characterization of aerosol radiative forcing over a semi-continental site Tripura, which is a strategic location in the western part of NEI having close proximity to the outflow of the IGP. Continuous long term measurements of aerosol black carbon (BC) mass concentrations and columnar aerosol optical depth (AOD) are used for the estimation of aerosol radiative forcing in each monthly time scale. The study revealed that the surface forcing due to aerosols was higher during both winter and pre-monsoon seasons, having comparable values of 32W/m(2) and 33.45W/m(2) respectively. The atmospheric forcing was also higher during these months due to increased columnar aerosol loadings (higher AOD ~0.71) shared by abundant BC concentrations (SSA ~0.7); while atmospheric forcing decreased in monsoon due to reduced magnitude of BC (SSA ~0.94 in July) as well as columnar AOD. The top of the atmosphere (TOA) forcing is positive in pre-monsoon and monsoon months with the highest positive value of 3.78W/m(2) in June 2012. The results are discussed in light of seasonal source impact and transport pathways from adjacent regions.

    Cryptococcus neoformans and Cryptococcus gattii are aetiological agents of cryptococcosis, a major opportunistic systemic mycosis of increasing global importance. This study reports the antifungal susceptibility profiles of clinical and environmental isolates of C. neoformans var. grubii, genotype VNI/AFLP1 (n = 246), and C. gattii serotype B, genotype VGI/AFLP4 (n = 62), originating from patients and environmental sources in north-western India. All of the C. neoformans var. grubii and C. gattii isolates were mating type α. Using the broth microdilution method, both species were found to be susceptible to the antifungals tested except for two clinical C. neoformans var. grubii isolates that were resistant to 5-flucytosine (MIC >64 µg ml⁻¹). Data on the geometric mean of MICs revealed that C. gattii was significantly less susceptible than C. neoformans var. grubii to fluconazole, itraconazole and voriconazole (P<0.0001). In addition, the MIC₉₀ of C. gattii was twofold higher than that of C. neoformans var. grubii for fluconazole, itraconazole and voriconazole. However, no statistically significant difference in susceptibility of the two Cryptococcus species was observed against amphotericin B and 5-flucytosine. Furthermore, the environmental C. neoformans var. grubii isolates were significantly less susceptible to fluconazole, itraconazole and 5-flucytosine (P<0.0001) than the clinical isolates. A continued surveillance of antifungal susceptibility of clinical and environmental strains of C. neoformans and C. gattii is desirable to monitor the emergence of any resistant strains in order to ensure more successful therapy of cryptococcosis.

    Context: Thoracic trauma causes significant morbidity; however, many deaths are preventable and few patients require surgery. Intercostal chest drainage (ICD) for hemo/pneumothorax is simple and effective; the main problem is residual hemothorax, which can cause lung collapse and empyema. Aims: Our study aimed to analyze the relationship between radiological chest tube parameters (position and intrathoracic length) and the frequency of residual hemothorax. Settings and Design: This prospective analytical study was conducted in a large tertiary care hospital in north India over 2 years till March 2013. Materials and Methods: Patients of chest trauma aged 18-60 years, with hemothorax or hemopneumothorax requiring ICD insertion were included in the study. Bedside ICD insertion was performed as per current standards. Immediate post-ICD chest radiographs were used to record lung status and ICD position (chest tube zone and intrapleural length). Residual hemothorax was defined as any collection identified on radiological investigations after 48 hours of ICD placement. Statistical Analysis: Univariate analysis was performed with the chi-square test or Student's t-test as appropriate, while multivariate analysis using stepwise logistic regression; a P-value < 0.05 was significant. Results: Out of 170 patients of chest trauma, 154 underwent ICD insertion. Most patients were young (mean age: 31.7 ± 12 years) males (M:F = 14:1). Ninety-seven patients (57.1%) had isolated chest injuries. Blunt trauma (n = 119; 77.3%) and motor vehicle accidents (n = 72; 46.7%) were the commonest causes. Mean hospital stay was 9 ± 3.94 days, and mortality 2/154 (1.1%). Residual hemothorax was seen in 48 (31%). No ICD zone or length was significantly associated with residual hemothorax on univariate or multivariate analysis. Conclusion: Intrapleural ICD zone or length does not affect the frequency of residual hemothorax. PMID:25400388

    Context: Ocimum basilicum L. (Lamiaceae) commonly known as sweet basil, has been used as a traditional medicinal plant for the treatment of headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunctions. Materials and Methods: The essential oil of the flowering aerial parts of O. basilicum growing in the Western Ghats region of North West Karnataka, India, was obtained by hydro-distillation and analyzed by gas chromatography equipped with flame ionization detector and gas chromatography coupled to mass spectrometry (GC–MS). The oil was tested against six Gram-positive, eight Gram-negative bacteria, and three fungi by the tube-dilution method at a concentration range of 5.00-0.009 mg/mL. Results: Twenty-five constituents were identified in the essential oil of O. basilicum. The major constituents were identified as methyl eugenol (39.3%) and methyl chavicol (38.3%), accounting for 98.6% of the total oil. The oil was found to be active against Gram-positive, Gram-negative bacteria, and fungi with minimal bactericidal concentration values in the range of 0.143 ± 0.031 to 0.572 ± 0.127 mg/mL, 0.781 ± 0.382 to 1.875 ± 0.684 mg/mL, and 0.312 ± 0.171 to 0.442 ± 0.207 mg/mL, respectively. Conclusion: The essential oil of O. basilicum of this region contains methyl eugenol/methyl chavicol chemotype and has bactericidal properties. PMID:25538349

    Background The study investigated the presence of CTX-M-15 type extended spectrum beta-lactamases (ESBL), compared their genetic arrangements and plasmid types in gram negative isolates of hospital and food origin in north-east India. From September 2013 to April 2014, a total of 252 consecutive, non-duplicate clinical isolates and 88 gram negative food isolates were selected. Phenotypic and molecular characterization of ESBL genes was performed. Presence of integrons and gene cassettes were analyzed by integrase and 59 base-element PCR respectively. The molecular environments surrounding blaCTX-M and plasmid types were investigated by PCR and PCR-based replicon typing respectively. Transformation was carried out to assess plasmid transfer. Southern blotting was conducted to localize the blaCTX-M-15 genes. DNA fingerprinting was performed by ERIC-PCR. Results Prevalence of ESBL was found to be 40.8% (103/252) in clinical and 31.8% (28/88) in food-borne isolates. Molecular characterization revealed the presence of 56.3% (58/103) and 53.5% (15/28) blaCTX-M-15 in clinical and food isolates respectively. Strains of clinical and food origin were non-clonal. Replicon typing revealed that IncI1 and IncFII plasmid were carrying blaCTX-M-15 in clinical and food isolates and were horizontally transferable. The ISEcp1 element was associated with blaCTX-M-15 in both clinical and food isolates. Conclusions The simultaneous presence of resistance determinants in non-clonal isolates of two different groups thus suggests that the microbiota of common food products consumed may serve as a reservoir for some of the drug resistance genes prevalent in human pathogens.

    Introduction The World Health Organization global strategy of promoting oral health have shown vast improvements in developed countries but the scenario is glum among underprivileged communities due to lacunae in implementation of these promotional programs. Manipur, a North Eastern state in India, is one such marginalized area. Aim The study aimed to evaluate Knowledge, Attitude and Practice (KAP) towards oral health in 15-18 year adolescents residing in Manipur together with the association of these variables to sociodemographic factors. Materials and Methods This cross-sectional study included 810 healthy adolescents drawn from various primary health care centers spanning in all the nine districts of Manipur. A closed ended questionnaire for the purpose of collecting data was used in the survey. Results Of the total participants 90.9% had high knowledge, 79.8% had favorable attitude and 70.4% had adequate practice towards oral health. Education of the parents and respondents was the only factor significantly associated with all three variables, knowledge, attitude and practice. Significant and positive linear correlation between knowledge-attitude (r=0.369, p<0.01) knowledge-practice (r=0.405, p<0.01) and attitude-practice (r =0.353, p<0.01), were observed. Conclusion An overwhelming majority of the respondents had high knowledge, favorable attitude and sound practice with respect to oral health. A positive linear correlation exists between the knowledge, attitude and practice. Evidence based reinforcement programs should be introduced to further reduce the gap between knowledge, attitude and practice. The study will also serve as a reference value for use in future evaluation to help measure the effectiveness of the planned activities. Future research needs to focus on establishing the dental caries prevalence and oral hygiene status of Manipuri youth. PMID:27504414

    Background/Aims Patients with inflammatory bowel disease (IBD) often require immunosuppressive therapy and blood transfusions and therefore are at a high risk of contracting infections due to hepatitis B (HBV) and hepatitis C (HCV) and human immunodeficiency virus (HIV). In the present study, we assessed the prevalence of these infections in patients with IBD. Methods This retrospective study included 908 consecutive patients with IBD (ulcerative colitis [UC], n=581; Crohn's disease [CD], n=327) who were receiving care at a tertiary care center. Ninety-five patients with intestinal tuberculosis (ITB) were recruited as disease controls. Prospectively maintained patient databases were reviewed for the prevalence of HBV surface antigen, anti-HCV antibodies, and HIV (enzyme-linked immunosorbent assay method). HCV RNA was examined in patients who tested positive for anti-HCV antibodies. Prevalence data of the study were compared with that of the general Indian population (HBV, 3.7%; HCV, 1%; HIV, 0.3%). Results The prevalence of HBV, HCV, and HIV was 2.4%, 1.4%, and 0.1%, respectively, in the 908 patients with IBD. Among the 581 patients with UC, 2.2% (12/541) had HBV, 1.7% (9/517) had HCV, and 0.2% (1/499) had HIV. Among the 327 patients with CD, 2.8% (8/288) had HBV, 0.7% (2/273) had HCV, and 0% (0/277) had HIV. One patient with CD had HBV and HCV coinfection. The prevalence of HBV, HCV, and HIV in patients with ITB was 5.9% (4/67), 1.8% (1/57), and 1.2% (1/84), respectively. Conclusions The prevalence of HBV, HCV, and HIV in north Indian patients with IBD is similar to the prevalence of these viruses in the general community. Nonetheless, the high risk of flare after immunosuppressive therapy mandates routine screening of patients with IBD for viral markers. PMID:28239319

    Ultramafic and mafic rocks occur within a linear belt, trending nearly E-W along North Puruliya Shear Zone of the Chhotanagpur Gneissic Complex (CGC). These rocks are classified as gabbro, norite, gabbro-norite, dolerite, diorite, olivine-websterite and lherzolite. Mafic rocks (Group 1) often occur in association with ultramafic variants (Group 2) and sometimes in isolation. A genetic link has been established between these mafic and ultramafic rocks using disposition of ultramafic and mafic rocks in the outcrop, systematic variation in modal mineralogy, co-linearity of plots in biaxial chemical variation diagram. Chemical composition of biotite and clinopyroxene reveal calc-alkaline nature and arc signature in these mafic-ultramafic rocks and whole rock geochemical characters indicate similarity with arc magma in subduction zone setting. The high values of Mg no. (47-81) and Al 2 O 3 (5.5-17.9) of mafic rocks indicate primitive, aluminous nature of the parental melt and presence of amphibole and biotite indicate its hydrous nature. The parent mafic melt evolved through fractionation of olivine, spinel, clinopyroxene and plagioclase. The crystal cumulates gave rise to the ultramafic rocks and the associated mafic rocks formed from residual melt. Crustal contamination played an important role in magmatic evolution as evident from variation in abundance of Rb in different lithomembers. Mafic-ultramafic rocks of the present study have been compared with intra-cratonic layered complexes, mafic-ultramafic rocks of high grade terrain, Alaskan type ultramafic-mafic complex and ophiolites. It is observed that the ultramafic-mafic rocks of present study have similarity with Alaskan type complex.

    Introduction: Head and neck cancer (HNCA) patients have poor nutritional status which clearly bears a negative prognosis in cancer. There is no study and consensus on nutritional assessment tools and diet structure for such patients. This study intends to determine the prevalence of malnutrition and formulate a diet chart keeping in view the general food habit and economic condition of HNCA patients of North East (NE) region. Aim: To find out an affordable dietary intervention for HNCA patients based on dietary principles. To assess the role of nutritional assessment tools in these group of patients. Materials and Methods: This is a 1-year prospective interventional study on HNCA patients attending the Dept of ENT of a teaching hospital. The outcome of the nutritional intervention using a specific diet were assessed using clinical, laboratory and anthropomorphic assessment tools and indices like Prognostic Nutritional Index (PNI) and Nutritional Assessment Index (NAI). Results: The study diet provided appropriate amounts of nutrients to HNCA patients as evident from improvements in anthropomorphic parameters and nutritional indices. Clinically, Hemoglobin percentage (Hb%), Body Mass Index (BMI), Mid Arm Circumference (MAC) and triceps skin fold thickness (TST) were found to be reliable malnutrition markers. Conclusion: Nutritional Assessment Index has been found to be the best index to evaluate malnutrition. The daily requirement of nutrients for HNCA patients can be satisfactorily met by adopting specific diet chart presented in our study. As no structured diet plan are available in literature, our diet chart can act as a template diet appropriate for HNCA patients of this region. PMID:26600696

    Leaf curl disease is a serious constraint in tomato production throughout India. Several begomoviruses were reported from different parts of the country; however, identity of begomovirus associated with leaf curl disease in tomato in north-eastern states of India was obscured. In the present study, the complete genome of an isolate (To-Ag-1) of begomovirus was generated from a leaf curl sample collected from Tripura state. However, no DNA-B and betasatellite were detected in the field samples. The genome of To-Ag-1 isolate contained 2,755 nucleotides that shared 94.7 % sequence identity with Tobacco curly shoot virus (TbCSV) and 71.3-90.1 % sequence identity with the other tomato-infecting begomoviruses occurring in the Indian subcontinent. Several inter-specific recombination events among different tomato-infecting begomoviruses from India and intra-specific recombination among different isolates of TbCSV reported from China were observed in the genome of To-Ag-1 isolate. Agroinoculation of the virus alone produced leaf curl symptoms in tomato and Nicotiana benthamiana. However, co-inoculation with a non-cognate betasatellite, Croton yellow vein mosaic betasatellite (CroYVMB) with the TbCSV resulted in increased severity of the symptoms both in tomato and N. benthamiana. Systemic distribution of the TbCSV and CroYVMB was detected in the newly developed leaves of tobacco and tomato, which showed ability of TbCSV to trans-replicate CroYVMB. The present study for the first time provides evidence of occurrence of TbCSV in tomato in north-eastern region of India and showed increased virulence of TbCSV with a non-cognate betasatellite.

    Background and Aim In health, TLR signaling protects the intestinal epithelial barrier and in disease, aberrant TLR signaling stimulates diverse inflammatory responses. Association of TLR polymorphisms is ethnicity dependent but how they impact the complex pathogenesis of IBD is not clearly defined. So we propose to study the status of polymorphisms in TLR family of genes and their effect on cytokines level in UC patients. Methods The genotypes of the six loci TLR1-R80T, TLR2-R753Q, TLR3-S258G, TLR5-R392X, TLR5-N592S and TLR6-S249P were determined in 350 controls and 328 UC patients by PCR-RFLP and sequencing. Cytokine levels were measured by ELISA in blood plasma samples. Data were analyzed statistically by SPSS software. Results TLR5 variants R392X and N592S showed significant association (p = 0.007, 0.021) with UC patients but TLR 1, 2, 3, 6 variants did not show any association. Unlike other studies carried out in different ethnic groups, TLR 6 (S249P) SNP was universally present in our population irrespective of disease. Genotype-phenotype correlation analysis revealed that the patients having combination of multiple SNPs both in TLR5 and TLR4 gene suffered from severe disease condition and diagnosed at an early age. The level of TNFα (p = 0.004), IL-6 (p = 0.0001) and IFNγ (p = 0.006) significantly increased in patients as compared to controls having wild genotypes for the studied SNPs. However, there was decreased level of TNFα (p = 0.014), IL-6 (p = 0.028) and IFNγ (p = 0.001) in patients carrying TLR5-R392X variant as compared to wild type patients. Patients carrying two simultaneous SNPs D299G in TLR4 gene and N592S in TLR5 gene showed significant decrease in the levels of TNFα (p = 0.011) and IFNγ (p = 0.016). Conclusion Polymorphisms in TLR 5 genes were significantly associated with the UC in North Indian population. The cytokine level was significantly modulated in patients with different genotypes of TLR4 and TLR5 SNPs. PMID:25789623

    A comprehensive study was conducted on chemical characterization of size segregated and cumulative aerosols during winter, 2015 and summer 2016 over a remote mangrove forest at Sundarban at the north-east coast of Bay of Bengal. Aerosols originated from the surf zone at the land-ocean boundary of Sundarban mangrove forest and aerosols advected from Kolkata and other metropolitan and urban cities at Indo-Gangetic Plain were characterized in terms of major water soluble inorganic species. Attempt was made to investigate the combined effect of locally generated sea-salt and advected anthropogenic aerosols could change the pristine marine character at this region during the above mentioned periods. Significant chloride depletion from sea-salt aerosols was observed in coarse and ultrafine mode compared to fine mode in winter whereas reverse trend was observed during summer. On an average the chloride to sodium ratio in PM10 aerosol was found to be around 0.6 which was much lower than that in sea-water. It was observed that non-sea-sulphate and nitrate aerosols were the major species depleting chloride from sea-salt aerosols. This supported the interaction between fresh marine and polluted anthropogenic aerosols. The average concentration of PM10 aerosols was 64 μg m-3 in winter and 89 μg m-3 in summer. Major water soluble ionic species were used for the source apportionment of aerosol during the two seasons. On an average it was observed that 60-70 % of total PM10 aerosols were constituted by the major water soluble ionic species. Emission flux and deposition flux of aerosols were also studied over this remote forest region. It was also observed that anthropogenic ionic species were mostly accumulated in the ultrafine and fine mode region both during winter and summer. On the other hand sea-salt species were mostly accumulated in the coarse mode region. Sulphate aerosol showed bimodal distribution with prominent peaks both at ultrafine/fine and coarse mode region

    Regional characterization of atmospheric aerosols is essential from the viewpoint of reducing the current uncertainties in the understanding of their climate implications at regional and global scale. The north-eastern part of India owing to its unique topography and geography located at sub Himalayan range and the middle of Indian Subcontinent and South-East Asian region as well as with scattered local hilly regions persevere complex aerosol environment. Collocated measurements of parameters corresponding to aerosol optical and physical properties i.e., spectral aerosol optical depths (AODs) by a 10 channel Multi-Wavelength solar Radiometer (MWR), near surface aerosol mass concentration of composite aerosols by a Quartz Crystal Microbalance Impactor (QCM) and Black Carbon (BC) mass concentration by an Aethalometer have been used in the Optical Properties of Aerosols and Clouds (OPAC) model to estimate the optical properties of composite aerosols over Dibrugarh (27.3ºN, 94.6ºE, 111 m amsl) for the short wavelength range. The OPAC outputs are then used as inputs to the Rdiative Transfer model ‘Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART)’, developed by the University of California, Santa Barbara, to derive the shortwave aerosol radiative properties. The aerosol optical depth shows maximum value in pre-monsoon season and minimum in post-monsoon season. Columnar aerosols are bimodal in nature with dominant contribution from fine mode aerosols. Unlike columnar aerosols surface aerosol concentration including black carbon shows maximum value in winter and minimum in monsoon season. The aerosol radiative forcing (ARF) estimated for the period pre-monsoon 2008-winter 2013 shows maximum value in the pre-monsoon season at the surface as well as in the atmosphere corresponding to highest columnar aerosol loading. The surface forcing varies between -37 Wm-2 in Pre-monsoon 2009 and 2011 to -13 Wm-2 in Post-monsoon 2008 while forcing in the Atmosphere

    The organic complexes taken for the present investigations are the locally available natural ( Plant and Silk ) fibres which are composed of macromolecular crystall-ographic structures. The readily available synthetic Polyester fibres are also used for their thermo-physical studies so as to findout the means about the possibility of blending of these fibres with natural fibres for their textile and other industrial utilities. Detailed studies on thermal behaviours of the plant ( Ramie, Jute and Cotton ) and synthetic Polyester fibres under different conditions have been under taken by various methods such as X-ray diffraction ( XRD ), Scanning Electron Microscopy ( SEM ), Infrared ( IR ) Spectroscopy, Differential Thermal Analysis ( DTA ), Differential Scanning Calorimetry ( DSC ), Thermo-gravimetry ( TG ), Derivative Thermo- gravimetry (DTG), Dielectric properties and DC Conductivity Analysis. In addition to the plant fibres, the locally available silk fibres ( Muga, Eri and Pat ) are also used to study the various thermo dynamical properties. Some portions of each fibrous raw products, collected from different localities of North Eastern Region of India, have been degummed. The thermal treatments ( Such as annealing and quenching ) of some part of the fibres have been made upto the temperature quite below to their decomposition points. The crystallinity and structural behaviours of raw, degummed and thermally treated fibrous samples have been studied by X-ray diffraction analysis. The detection of functional groups and their behaviours under different thermal conditions have been made by infrared spectroscopy. The surface features have been studied by Scanning Electron Microscopic photographs. The detailed investigations on thermodynamical properties of silk, plant and synthetic fibres have been carriedout by DTA, DSC, TG and DTG techniques. The experiments have been carriedout in the temperature range from 298K to 673K. The two steps activities dehydration and

    The state of Assam in north-east India gained popularity in Asia because of discovery of oil. Pollution due to petroleum and gas exploration is a serious problem in Assam. Oil and gas exploration by various agencies in Assam resulted in soil pollution due to hydrocarbons (HCs) and heavy metals (HMs). Bioremediation gained considerable significance in addressing petroleum hydrocarbon polluted sites in various parts of the world. In this investigation, we have observed 15 species of plants belonging to grass growing on the contaminated soils. Among 15 species of grasses, 10 species with high important value index (IVI) were found to be better adapted. The highest IVI is exhibited by Axonopus compressus (21.41), and this grass can be identified as key ecological tool in the rehabilitation of the degraded site. But no definite correlation between the IVI and the biomass of the various grass existed in the study sites. Chemical study of rhizosphere (RS) and non-rhizosphere (NRS) soil of these grasses revealed both aromatic and aliphatic compounds (M.W. 178-456). Four-ring pyrene was detected in NRS soil but not in RS soil. Microbiological study of RS and NRS soil showed high colony-forming unit (CFU) of HC-degrading microbes in RS compared to NRS. The increased microbial catabolism in RS soil established the fact that pyrene is transformed to aliphatic compounds. Metals in RS soil ranged from (in mg kg(-1)) 222.6 to 267.3 (Cr), 854 to 956 (Pb) and 180 to 247 (Ni), but despite the very high total metal concentration in RS and NRS soil, the CaCl2-extracted metals were relatively low in RS soil (1.04 for Cr, 0.56 for Pb, 0.35 for Ni). Plants with the highest uptake of metals were Leersia hexandra (36.43 mg Cr kg(-1)) and Kyllinga brevifolia (67.73 mg Pb kg(-1) and 40.24 mg Ni kg(-1)). These plant species could be potentially exploited for biomonitoring and bioremediation. Out of 15 plant species, 8 of them have high percentages of cellulose, crude fibres, lignin

    Indoor air quality and heat exposure have become an important occupational health and safety concern in several workplaces including kitchens of hotels. This study investigated the heat, particulate matter (PM), total volatile organic compounds (TVOCs) and polycyclic aromatic hydrocarbons (PAHs) emissions in indoor air of commercial kitchen and its association with kidney dysfunctions among kitchen workers. A cross sectional study was conducted on 94 kitchen workers employed at commercial kitchen in Lucknow city, North India. A questionnaire-based survey was conducted to collect the personal and occupational history of the kitchen workers. The urine analysis for specific gravity and microalbuminuria was conducted among the study subjects. Indoor air temperature, humidity, wet/ dry bulb temperature and humidex heat stress was monitored during cooking activities at the kitchen. Particulate matter (PM) for 1 and 2.5 microns were monitored in kitchen during working hours using Hazdust. PAHS in indoor air was analysed using UHPLC. Urinary hydroxy-PAHs in kitchen workers were measured using GC/MS-MS. Higher indoor air temperature, relative humidity, PM1 and PM2.5 (p<0.001) was observed in the kitchen due to cooking process. Indoor air PAHs identified are Napthalene, fluorine, acenaphthene, phenanthrene, pyrene, chrysene and indeno [1,2,3-cd) pyrene. Concentrations of all PAHs identified in kitchen were above the permissible OSHA norms for indoor air. Specific gravity of urine was significantly higher among the kitchen workers (p<0.001) as compared to the control group. Also, the prevalence of microalbuminuria was higher (p<0.001) among kitchen workers. Urinary PAH metabolites detected among kitchen workers were 1-NAP, 9-HF, 3-HF, 9-PHN and 1-OHP. Continuous heat exposure in kitchens due to cooking can alter kidney functions viz., high specific gravity of urine in kitchen workers.

    Lactic acid bacteria (LAB) isolated from various foods are important due to their potential to inhibit microorganisms, including drug-resistant bacteria. The objectives of this investigation were to isolate and identify antibacterial substances producing LAB from Hentak, a traditional fermented fish product of Manipur (North-East India), and to optimize the production of antagonistic substances present in cell free neutralized supernatant (CFNS) against enteric bacterial pathogens using the 'one factor at a time' (OFAT) method. Out of 10 LAB, the most potent bacterium producing antibacterial substances was isolated and identified as Lactobacillus pentosus strain LAP1 based upon morphological, biochemical and molecular characterization. MRS (de Man, Ragosa and Sharpe) medium was determined to provide better bactericidal activity (AU/ml) than other tested media against the indicator enteric bacteria, including Staphylococcus epidermidis MTTC 3615, Micrococcus luteus MTCC 106, Shigella flexneri MTCC 1457, Yersinia enterocolitica MTCC 840 and Proteus vulgaris MTCC 1771. The culture conditions (pH: 5, temperature: 30 °C and inoculum volume: 1 %) and medium components (carbon source: lactose and nitrogen source: ammonium chloride) were observed to be the most influential parameters of significant antagonistic activity of CFNS against the enteric pathogens. MRS medium supplemented with Tween20 effectively stimulated the yield of antibacterial substances. The CFNS of strain LAP1 exhibited sensitivity to proteolytic enzyme (pepsin) treatment and heat treatment (60 °C for 60 min, 100 °C for 30 min and 121 °C for 15 min) and lost its inhibitory properties. The CFNS was active at an acidic (pH 3.0) to neutral pH (pH 7.0) but lost its antagonistic properties at an alkaline pH. The CFNS obtained from strain LAP1 scavenges the DPPH (1,1-diphenyl-2 picrylhydrazyl) significantly in a concentration-dependent manner within the range of 8.8 ± 0.12-57.35 ± 0.1 %. The

    The Archean East Indian cratonic margin was affected by the Kerguelen plume (KP) ˜117 Ma, causing flood-basalt eruptions of the Rajmahal-Bengal-Sylhet Traps (RBST). The RBST cover ˜one million km2 in and around the Bengal Basin as alkalic-ultrabasic intrusives in the west and Sikkim in the north, and Sylhet basalts and alkalic-carbonatitic-ultramafic complexes in the Shillong plateau - Mikir hills farther east of the Rajmahal-Bengal Traps. We provide new Nd-Sr-Pb-isotopic and trace element data on 21 unreported discrete lava flows of the Rajmahal Traps, 56 alkalic-carbonatitic-mafic-ultramafic rocks from four alkalic complexes, and three dikes from the Gondwana Bokaro coalfields, all belonging to the RBST. The data allow geochemical correlation of the RBST with some contemporaneous Kerguelen Plateau basalts and KP-related volcanics in the southern Indian Ocean. Specifically, the new data show similarity with previous data of Rajmahal group I-II basalts, Sylhet Traps, Bunbury basalts, and lavas from the southern Kerguelen Plateau, indicating a relatively primitive KP source, estimated as: ɛNd(I) = +2, 87Sr/86Sr(I) = 0.7046, with a nearly flat time-integrated rare earth element (REE) pattern. We model the origin of the uncontaminated RBST basalts by ˜18% batch melting with a 2× chondritic KP source in the spinel-peridotite stability depths of 60-70 km in the mantle. The new geochemical data similar to the Rajmahal group II basalts indicate a light REE enriched average source at ɛNd(I) = -5, 87Sr/86Sr(I) = 0.7069. Our geochemical modeling indicates these lavas assimilated granulites of the Eastern Ghats, reducing the thickness of the continental Indian lithosphere. Lack of an asthenospheric MORB component in the RBST province is indicated by various trace element ratios as well as the Nd-Sr isotopic ratios. Three alkalic complexes, Sung, Samchampi, and Barpung in NE India, and one in Sikkim to the north are of two groups: carbonatites, pyroxenites, lamproites

    Summary Background In north India, vitamin A deficiency (retinol <0·70 μmol/L) is common in pre-school children and 2–3% die at ages 1·0–6·0 years. We aimed to assess whether periodic vitamin A supplementation could reduce this mortality. Methods Participants in this cluster-randomised trial were pre-school children in the defined catchment areas of 8338 state-staffed village child-care centres (under-5 population 1 million) in 72 administrative blocks. Groups of four neighbouring blocks (clusters) were cluster-randomly allocated in Oxford, UK, between 6-monthly vitamin A (retinol capsule of 200 000 IU retinyl acetate in oil, to be cut and dripped into the child's mouth every 6 months), albendazole (400 mg tablet every 6 months), both, or neither (open control). Analyses of retinol effects are by block (36 vs 36 clusters). The study spanned 5 calendar years, with 11 6-monthly mass-treatment days for all children then aged 6–72 months. Annually, one centre per block was randomly selected and visited by a study team 1–5 months after any trial vitamin A to sample blood (for retinol assay, technically reliable only after mid-study), examine eyes, and interview caregivers. Separately, all 8338 centres were visited every 6 months to monitor pre-school deaths (100 000 visits, 25 000 deaths at ages 1·0–6·0 years [the primary outcome]). This trial is registered at ClinicalTrials.gov, NCT00222547. Findings Estimated compliance with 6-monthly retinol supplements was 86%. Among 2581 versus 2584 children surveyed during the second half of the study, mean plasma retinol was one-sixth higher (0·72 [SE 0·01] vs 0·62 [0·01] μmol/L, increase 0·10 [SE 0·01] μmol/L) and the prevalence of severe deficiency was halved (retinol <0·35 μmol/L 6% vs 13%, decrease 7% [SE 1%]), as was that of Bitot's spots (1·4% vs 3·5%, decrease 2·1% [SE 0·7%]). Comparing the 36 retinol-allocated versus 36 control blocks in analyses of the primary outcome, deaths per child

    The gut bacteria exert phenotypic traits to the host but the factors which determine the gut bacterial profile (GBP) is poorly understood. This study aimed to understand the effect of ethnicity and geography on GBP of Mongoloid and Proto-Australoid tribes of India. Fecal bacterial diversity was studied in fifteen tribal populations representing four geographic regions (Assam, Telangana, Manipur and Sikkim) by DGGE followed by NGS analysis on Illumina MiSeq platform. Geography and diet had significant effect on GBP of the Indian tribes which was dominated by Prevotella. The effects were more prominent with lower taxonomic levels, indicating probable functional redundancy of the core GBP. A comparison with the worldwide data revealed that GBP of the Indian population was similar to the Mongolian population (Mongolia). The bacterial genera Faecalibacterium, Eubacterium, Clostridium, Blautia, Ruminococcus and Roseburia were found to be core genera in the representative populations of the world. PMID:26689136

    The Archean East Indian craton was affected by the Kerguelen plume at ~117 Ma causing flood-basalt eruptions at the cratonic margin giving rise to the Rajmahal-Bengal-Sylhet Traps. Rajmahal-age volcanics are wide-spread in and around the Bengal Basin, from the intrusive lamproites and lamprophyres in the west and Sikkim in the north, to the Sylhet basalts and alkalic-carbonatitic-ultramafic intrusives of the Shillong plateau and the Mikir hills in northeastern India. These volcano-plutonic complexes are exposed over an approximate area of 0.8 million km2 in and around the Bengal Basin. This study demonstrates that all these diverse volcanic rocks are caused by the Kerguelen plume activity. We provide isotopic and geochemical data of the Rajmahal Traps, and associated alkalic-carbonatitic-mafic-ultramafic complexes, and relate them to the Sylhet Traps in northeastern India, some contemporaneous Kerguelen Plateau basalts, and associated volcanics in the Southern Indian Ocean. Specifically, we report here Nd-Sr-Pb-isotopic and multiple trace element data of discrete lava flows from the Rajmahal Traps; mafic, alkalic, ultrabasic, and carbonatitic rocks from four alkalic complexes, and three ultramafic dikes from the Bokaro coal fields southwest of the Rajmahal Traps. In Nd-Sr-Pb isotopes, the Rajmahal Traps lavas of this study show remarkable similarity with previously reported Rajmahal Groups I and II basalts, Sylhet Traps, Bunbury basalts and lavas from the southern Kerguelen Plateau. The combined geochemical data and their correlation with the Rajmahal, Bunbury basalts, and some Kerguelen Plateau lavas in the Indian Ocean imply a relatively primitive Kerguelen plume source for the Rajmahal lavas similar to the Rajmahal Group I basalts. We estimate the average composition of this plume source to be: ɛNd(I)=+2, 87Sr/86Sr(I)=0.7045, with relatively flat rare earth element (REE) patterns. Rajmahal lavas similar to the Group II Rajmahal basalts have slightly enriched

    2014-01-01

    Background Neutralizing antibodies in breast milk may adversely influence the immune response to live oral vaccines. Withholding breastfeeding around the time of vaccine administration has been suggested for improving vaccine performance. However, we do not know whether mothers find withholding breastfeeding around the time of vaccination acceptable and how they perceive this recommendation. Methods In a clinical study designed to examine predictors of poor immune response to rotavirus vaccine in infants in India, Rotarix® was administered to infants at 6 and 10 weeks with other childhood vaccines. For the study, 400 mother–infant pairs were randomized into two groups in a 1:1 ratio. Mothers were either recommended to withhold breastfeeding or were encouraged to breastfeed half an hour before and after administration of Rotarix®. The mother–infant pairs were observed and the breastfeeding intervals were recorded during this period. Mothers were administered a questionnaire about their perception of the intervention after the infants received the second dose of Rotarix®. Results Almost 98% (391/400) of the infants received both doses of Rotarix®. Adherence to the recommendations was high in both groups. All mothers in the group who were asked to withhold breastfeeding did so, except one who breastfed her infant before the recommended time after the first dose of Rotarix®. Of the mothers, 4% (7/195) reported that the recommendation to withhold breastfeeding was difficult to follow. All mothers in this group reported that they would withhold breastfeeding at the time of vaccination if they were asked to by a health-care provider. Only one mother responded that withholding breastfeeding would be a reason for not giving rotavirus vaccine to her infant. Conclusions Withholding breastfeeding half an hour before and after vaccination appears to be acceptable to mothers in this setting. If withholding breastfeeding produces an improvement in the performance of the

    Familial hypercholesterolemia (FH) is an autosomal dominant disorder due to mutation of apolipoprotein-B receptor gene causing severe dyslipidemia. Lifestyle modification and medical treatment attenuate the disease progression, but as these fail to control the blood cholesterol levels, low-density lipoprotein (LDL) apheresis comes forth as a treatment option. To the best of our knowledge, the following is the very first case of pediatric FH being treated by LDL-apheresis to be reported from India. A severely malnourished female child presented with yellowish skin lesions over different parts of the body, viz., bilateral Achilles tendon, both knees, elbows, both pinnae, and outer canthus of both eyes. She had a strong family history of borderline hypercholesterolemia and was diagnosed as a case of FH. She was maintained on diet modification. LDL-apheresis was planned as the cholesterol levels were not controlled with the diet modificationt. However, unavailability of an appropriate kit in India for LDL-apheresis led to the use of the modified PL1 kit meant for therapeutic plasma exchange procedures. We conducted two sessions of LDL-apheresis. After the first session, the LDL-cholesterol (LDL-C) level fell by 75.9% and the total cholesterol fell by 73.5%. A second procedure led to a decline in total cholesterol level by 18.6% and LDL-C by 19.46%. Subsequently, she was advised diet modification and statin therapy with regular follow-up after every 6 months. Thus, the cascade filtration technique is a safe and effective treatment option for removing the undesired lipoproteins. PMID:28316443

    Abstract Background: Type 2 diabetes (T2D) statistics have reached menacing proportions in India. Appropriate dietary intervention, as part of healthy lifestyle, is imperative to curb further spread of this disease. Objectives: This pre–post intervention study was conducted in New Delhi, India, to investigate the effects of daily consumption of almonds for 24 weeks in T2D subjects, specifically on measures of glycemia and cardiovascular disease (CVD) risk factors. Methods and Study Design: In this study, the 24-week intervention period was preceded by a control diet and exercise run-in period of 3 weeks. Raw almonds (20% of energy intake) were provided to the patients for consumption along with diet and physical activity counseling. Patients were assessed for anthropometry, blood pressure, measures of glycemia (fasting blood glucose, glycosylated hemoglobin), lipids [total cholesterol (TC), triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, lipoprotein(a)], surrogate marker of atherosclerosis (Pulse wave velocity), and marker of inflammation (high sensitivity C-reactive protein [hs-CRP]) at baseline and after the intervention period. Results: Statistically significant improvement in mean values for various parameters post intervention was as follows: waist circumference (P < 0.03), waist-to-height ratio (P < 0.005), TC (P < 0.002), serum triglycerides (P < 0.004), low-density lipoprotein cholesterol (P < 0.01), glycosylated hemoglobin (P < 0.04), and hs-CRP (P < 0.01). A trend toward improvement in pulse wave velocity (P < 0.06) was also observed. Conclusion: The study findings illustrate that incorporation of almonds in a well-balanced healthy diet leads to multiple beneficial effects on glycemic and CVDs risk factors in Asian Indian patients with T2D.

    Groundwater happens to be a major source of drinking water for urban and rural India. With rapid growth in industrial sector, the shallow groundwater regime has become more vulnerable to industrial contamination and human activity. In this study, the drinking water quality of Gajraula and its suburbs, a semi-urbanized town of northern India, was assessed. The water samples from pre-identified 14 wells with different depths were analyzed for 2 years, i.e. 2008 and 2009. The samples were taken thrice a year in May (summers), August (monsoon) and December (winters). The compiled results were compared with recommended values of World Health Organization (WHO) and Bureau of Indian Standards (BIS) for drinking water. The analysis showed that concentration levels of TDS, BOD, NO3- and Ca2+ exceeded the desirable limits of WHO and BIS in certain wells. The levels of trace metals Fe and Pb exceeded the limits in almost all the wells, while pH, Cl-, SO42-, Mg2+, Zn, Cr and Ni were well within the limits. The contamination levels in most cases were higher during summers as compared to monsoon and winters, which may be due to high build-up of dissolved solids. The quality of water from shallow hand pumps in vicinity to industries were unsuitable for human consumption as compared to public deep bore wells. Agro-chemicals, irrigation by effluent discharge and wastewater from commercial cum residential area were the main sources of groundwater pollution. A study based on long-term surveillance of water systems, incorporating individual exposure assessment of users of private wells, should be considered for a lasting solution.

  2. The paleoposition of India

    NASA Astrophysics Data System (ADS)

    Chatterjee, Sankar; Hotton, Nicholas

    In most of the plate tectonic models of paleocontinental assembly, the supercontinent Pangea has been disassociated into independent Laurasia and Gondwana, separated by a vast oceanic Tethys. The position of India remains problematical, but geological and geophysical data support a Pangea reconstruction. Traditionally India has always been regarded as a part of Gondwana as it shares two unique geologic features with other southern continents. These are the Upper Paleozoic glacial strata and the Glossopteris flora. However, neither line of evidence definitely proves continuity of land; together they indicate zonation of cold climates. The recent discovery of Upper Paleozoic glacial strata in the U.S.S.R., southern Tibet, Saudi Arabia, Oman, China, Malaya, Thailand, and Burma demonstrates that the Permo-Carboniferous glaciation was far more extensive beyond the Gondwana limit than is usually thought. Similarly the Glossopteris flora has been found farther north of the Indian Peninsula, in the Himalaya, Kashmir and Tibet. Moreover the floral similarities are explained easily by wind and insect dispersal. On the other hand, the distribution of large terrestrial tetrapods is strongly influenced by the distribution of continents. To terrestrial tetrapods, sea constitutes a barrier. In consequence, they are more reliable indicators of past land connections than are plants, invertebrates and fishes. The postulated separation of India from Antarctica, its northward journey, and its subsequent union with Asia, as suggested by the plate tectonic models, require that during some part of the Mesozoic or Early Tertiary India must have been an island continent. The lack of endemism in the Indian terrestrial tetrapods during this period is clearly inconsistent with the island continent hypothesis. On the contrary, Indian Mesozoic and Tertiary vertebrates show closest similarities to those of Laurasia, indicating that India was never far from Asia. The correlation of faunal

    Background & objectives: Genetic polymorphisms in glutathione-S-transferase genes (GSTM1 and GSTT1) have been studied intensively for their potential role in lung cancer susceptibility. However, most of the studies on association between the polymorphisms and lung cancer do not distinguish between genotypes with one or two copies of the genes. The present study investigates the gene dosage effects of GSTT1 and GSTM1 copy number and their environmental interactions to examine the association of lung cancer risk with trimodular genotypes of the GSTs in a high-risk population from north-east India. Methods: A total of 154 lung cancer cases and 154 age and sex matched controls from the high risk region of north-east India were analyzed by multiplex real-time PCR to determine the trimodal genotypes (+/+, +/- and -/-) in both the genes (GSTM1 and GSTT1). Results: No significant association and gene dosage effect of GSTM1 gene copy number with lung cancer risk (Ptrend=0.13) were found. However, absence of GSTT1 conferred 68 per cent (OR=0.32;95%CI=0.15-0.71; P=0.005) reduced risk compared to the two copy number of the gene. There was evidence of gene dosage effect of GSTT1 gene (Ptrend=0.006). Tobacco smoking was a major environmental risk factor to lung cancer (OR=3.03;95%CI=1.73-5.31; P<0.001). However, its interaction with null genotype of GSTT1 conferred significant reduced risk to lung cancer (OR=0.30;95%CI=0.10-0.91; P=0.03). Further in only tobacco smokers, null genotype was associated with increased reduced risk [0.03(0.001-0.78)0.03; Ptrend=0.006]. No effect modification of GSTM1 was observed with lung cancer risk by environmental risk factors. Interpretation & conclusions: The results suggest that absence of GSTT1 null genotype may be associated with a reduced risk of lung cancer and the effect remains unchanged after interaction with smoking.

  4. Formation of Se (0) Nanoparticles by Duganella sp. andAgrobacterium sp. isolated from Se-laden soil of North-East Punjab, India

    PubMed Central

    2012-01-01

    Background Selenium (Se) is an essential trace element, but is toxic at high concentrations. Depending upon the geological background, the land use or on anthropogenic pollution, different amounts of Se may be present in soil. Its toxicity is related to the oxyanions selenate and selenite as they are water soluble and bioavailable. Microorganisms play an important role in Se transformations in soil and its cycling in the environment by transforming water-soluble oxyanions into water insoluble, non-toxic elemental Se (0). For this study, soil samples were collected from selenium-contaminated agricultural soils of Punjab/India to enrich and isolate microbes that interacted with the Se cycle. Results A mixed microbial culture enriched from the arable soil of Punjab could reduce 230 mg/l of water soluble selenite to spherical Se (0) nanoparticles during aerobic growth as confirmed by SEM-EDX. Four pure cultures (C 1, C 4, C 6, C 7) of Gram negative, oxidase and catalase positive, aerobic bacteria were isolated from this mixed microbial consortium and identified by 16 S rDNA gene sequence alignment as two strains of Duganella sp. (C 1, C 4) and two strains of Agrobacterium sp.(C 6, C 7). SEM/TEM-EDX analyses of the culture broth of the four strains revealed excretion of uniformly round sharply contoured Se (0) nanoparticles by all cultures. Their size ranged from 140–200 nm in cultures of strains C 1 and C 4, and from 185–190 nm in cultures of strains C 6 and C 7. Both Duganella sp. revealed better selenite reduction efficiencies than the two Agrobacterium sp. Conclusions This is the first study reporting the capability of newly isolated, aerobically growing Duganella sp. and Agrobacterium sp. from soils of Punjab/India to form spherical, regularly formed Se (0) nanoparticles from water soluble selenite. Among others, the four strains may significantly contribute to the biogeochemical cycling of Se in soil. Bioconversion of toxic selenite to non-toxic Se (0

    The volume change of Chhota Shigri Glacier (India, 32° N) between 1988 and 2010 has been determined using in-situ geodetic measurements. This glacier has experienced only a slight mass loss over the last 22 yr (-3.8 ± 1.8 m w.e.). Using satellite digital elevation models (DEM) differencing and field measurements, we measure a negative mass balance (MB) between 1999 and 2011 (-4.7 ± 1.8 m w.e.). Thus, we deduce a positive MB between 1988 and 1999 (+1.0 ± 2.5 m w.e.). Furthermore, satellite DEM differencing reveals a good correspondence between the MB of Chhota Shigri Glacier and the MB of an over 2000 km2 glaciarized area in the Lahaul and Spiti region during 1999-2011. We conclude that there has been no large ice wastage in this region over the last 22 yr, ice mass loss being limited to the last decade. This contrasts to the most recent compilation of MB data in the Himalayan range that indicates ice wastage since 1975, accelerating after 1990. For the rest of western Himalaya, available observations of glacier MBs are too sparse and discontinuous to provide a clear and relevant regional pattern of glacier volume change over the last two decades.

    To determine the frequency and genotypes of rotavirus strains, samples were collected from children hospitalized with acute diarrhea at the Regional Institute of Medical Sciences, Manipur. The globally common genotypes G1P[8] and G2P[4] constituted 58% of the total positive strains, while 3% and 8% strains were emerging genotypes, G9P[6] and G12P[6]. This is the first report of genotype G12 in Manipur. The G12 strains clustered with lineage III strains and had >98% identity with corresponding rotaviruses from Bangladesh, Thailand and the USA. Other uncommon G-P combinations including G4P[4], G4P[6], G10P[6] and G9P[19], along with a few strains that could not be typed were also found. The VP7 genes of G4 and G10 strains clustered with porcine and bovine strains, indicating possible zoonotic transmission. High frequency (36-62%) of rotavirus infection and predominance of G1P[8] and G2P[4] among children with acute diarrhea emphasized the need for implementation of currently available vaccines to reduce the burden of rotavirus induced diarrhea in India.

    Background: Alarming rise of vancomycin-resistant enterococci (VRE) is a global cause of concern. Several factors have been held responsible for such rise, of which antibiotic usage is a prominent one. Objective: This study was undertaken to determine the intestinal VRE colonization rate amongst hospitalized patients in relation to use of various antibiotics in the Intensive Care Unit (ICU) of a tertiary care university hospital, India. Materials and Methods: Stool samples were collected weekly from all the patients in the adult ICU for a period of 6 months and processed for isolation and phenotypic and genotypic characterization of VRE isolates. Patient and treatment details were noted and cases (those with VRE in stool) and controls (those without VRE in stool) were compared statistically. Further, a multivariate analysis was done to identify those antibiotics as independent risk factors for VRE colonization. Results: VRE colonization was found in 34.56% (28/81) of the patients studied, with the majority 75% (21/28) carrying the vanA gene. The cases had significantly more (P < 0.05) duration of hospital stay and antibiotic exposure. Intake of metronidazole, vancomycin, and piperacillin-tazobactam were identified as significant risk factors both in univariate and multivariate analysis. Conclusion: A potential reservoir of VRE was thus revealed even in low VRE prevalence setting. Based on this high colonization status, restriction of empirical antibiotic use, reviewing of the ongoing antibiotic policy, and active VRE surveillance as an integral part of infection control strategy were suggested.

    Human papillomavirus (HPV) associated cervical cancer is the leading cause of deaths in India. However, cytological/HPV screening may result in early detection of cervical cancer, resulting in early treatment and reduced mortality. Although reports related to general population is available, data on HPV prevalence among women attending AFMS health care facilities is scarce. Cervical samples were collected for cytological staining by Pap test and molecular detection by PCR, genotyping by HPV specific primers and sequencing. Apart from finding of atypical cells of undetermined significance (ASCUS) in one subject, no evidence of malignancy was observed. A high prevalence of HPV was found in this study group, which was intermediate between previous reports from general population and cervical cancer patients. All the subjects had infection of high risk HPV type16. HPV prevalence was found similar between different age groups. Although, none of the study subjects had malignant changes, but due to high prevalence of high risk HPV infection and other associated risk factors, these subjects might be at an elevated risk of developing cervical cancer. Regular follow-up of these patients who were detected HPV positive are required to screen for cervical malignancy. PMID:25859083

    Community-based participatory research has been seen to hold great promise by researchers aiming to bridge research and action in global health programs and practice. However, there is still much debate around whether achieving authenticity in terms of in-depth collaboration between community and academic partners is possible while pursuing academic expectations for quality. This article describes the community-based methodology for a qualitative study to explore intimate partner violence and HIV/AIDS among women in sex work, or female sex workers, and their male partners in Karnataka, South India. Developed through collaborative processes, the study methodology followed an interpretive approach to qualitative inquiry, with three key components including long-term partnerships, knowledge exchange, and orientation toward action. We then discuss lessons learned on how to pursue authenticity in terms of truly collaborative processes with inherent value that also contribute to, rather than hinder, the instrumental goal of enhancing the quality and relevance of the research outcomes.

    In order to assess the potential of wetland plants to remediate metals from a paper mill effluent contaminated wetland site in Northeast India, 25 abundant plant species belonging to 15 different families, soil, and water samples from the sites were tested for Pb, Zn, Mg, and Fe by atomic absorption spectrophotometer. The results showed that metal accumulation by wetland plants differed among species and tissues. Plants thrived in high Pb, Zn, Mg, and Fe which indicated their tolerance. According to the criteria used for selecting plants for phytoremediation such as high metal tolerance, short life cycle, wide distribution, large shoot biomass and translocation factor (TF) >1; five species each were Mg and Fe accumulators, nine species were Pb accumulators and, eight species were Zn accumulators and the rest were excluders. Alternanthera sessilis was the only plant species that had TF > 1 for all the four metals. The study indicated great promise for phytoremediation, as these accumulators could be used in future for practical phytoremediation approaches and reduction of the risk from harmful metals to human health.

    The present case study has been undertaken to investigate the impact of on-site sanitation on groundwater quality in alluvial settings in Lucknow City in India. The groundwater samples have been collected in the areas of Lucknow City where the on-site sanitation systems have been implemented. The groundwater samples have been analyzed for the major physicochemical parameters and fecal coliform. The results of analysis reveal that none of the groundwater samples exceeded the Bureau of Indian Standards (BIS) limits for all the parameters. Fecal coliform was not found in majority of the samples including those samples which were very close to the septic tank. The study area has a thick alluvium cover as a top layer which acts as a natural barrier for groundwater contamination from the on-site sanitation system. The t test has been performed to assess the seasonal effect on groundwater quality. The statistical t test implies that there is a significant effect of season on groundwater quality in the study area.

    Objective: To correlate serum estrogen levels with cognitive functions calculated objectively as per Mini Mental State Examination (MMSE) in the females in reproductive age group and those attaining menopause. Materials and methods: This study was conducted in Christian Medical College and Hospital, Ludhiana, Punjab, India. 150 subjects (100 postmenopausal females and 50 regularly menstruating females of the reproductive age group) were included. The cognitive functions of all the females and serum estrogen levels (i.e Estradiol E2) were assessed. Results: The E2 levels in normal menstruating females were found to be higher (mean = 188.062 pg/ml) as compared to the menopausal females and the difference in E2 levels was found to be significant (p < 0.001). However, the difference in serum estrogen levels of subjects in the two menopausal groups was insignificant. MMSE, showed that scores of normal menstruating females were higher (mean score = 29.92) as compared to post menopausal females for 1-5 years (mean score = 26.72) and post menopausal females for last 6-10 years (mean score = 26.30). Conclusion: We observed that the cognition functions declined in post menopausal women, whereas the scores were higher in the women of reproductive age group, meaning thereby, that it is the serum estrogen level that is bringing about this difference. Another finding was that the decline in cognition following menopause was not progressive. Therefore, this correlation would open up the gates for the use of estrogen therapy for various neuropsychological disorders pertaining to cognition in the postmenopausal females. PMID:26177471

    We prepared a consolidated list of edible and therapeutic insects used in Arunachal Pradesh (N.E. India) by two tribal societies (i.e., the Nyishi of East Kameng and the Galo of West Siang). The list is based on thorough, semi-structured field-interviews with 20 informants of each tribal group. At least 81 species of local insects, belonging to 26 families and five orders of insects, namely Coleoptera (24 species), Orthoptera (17 species), Hemiptera (16 species), Hymenoptera (15 species) and Odonata (9 species), are being used as food among members of these two indigenous societies. However, Nyishi use overall more species of insects as food than Galo people do and consume mostly Coleoptera and Hemiptera; amongst the Galo, on the other hand, Odonata and Orthoptera dominate. The selection of the food insects amongst the Nyishi and Galo is dictated by traditional tribal beliefs as well as the taste and availability of the insects. Depending on the species, only particular or all developmental stages are consumed. Some food insects may be included in the local diet throughout the year, others only when seasonally available. Commonly specimens are being prepared for consumption by roasting, frying or boiling. Twelve species of insects are deemed therapeutically valuable by the locals and are being used by the tribes investigated to treat a variety of disorders in humans and domestic animals. Members of the Galo use a greater number of insect species for remedial purposes than the Nyishi. With the degradation of natural resources, rapid population growth, and increasing influence of 'westernization', the traditional wisdom of entomophagy and entomotherapy is at risk of being lost. There is thus an urgent need to record the role insects play as components of local diets and folk remedies and to assess insect biodiversity in the light of these uses.

    Aerosol samples for PM 2.5 were collected at a suburban site of India during Jan 2007 to Jan 2008. The sampling site is exposed to different antropic source emissions like vehicular emission, wood burning, coal based industries and other industrial activities. The mass concentrations of PM 2.5, major elements (Al, Si, P, S, Na, K, Ca, Ti, V, Cr, Mn, Fe, Te, Co, Ni, Cu, Zn, Cd, Sn, Sb, and Pb) and major ions (Cl -, NO 3-, SO 42-, and NH 4+) were determined for winter and rainy seasons. Their levels were found higher than those of in various European and American cities, however, comparable to those of some Asian cities. Analysis of variance (ANOVA) showed significant seasonal variation for concentrations of PM 2.5, NO 3-, SO 42- and most of the elements. This seasonal variation is due to enhanced heating activities and stagnant climatic conditions in winter and removal of pollutants by wet deposition in the rainy period. Source apportionment was undertaken using enrichment factor (EF), Spearman's correlation and absolute principal component analysis. A five-factor model for explaining the observed PM 2.5 levels was found to provide realistic results. Evaluation of element abundance at site indicates different pollution levels. The source identification of this study shows that PM 2.5 levels were influenced by not only local and industrial activities but also long range transport. Traffic induced crustal sources (38%); coal combustion (26%), industrial and vehicular emissions (19%), wood burning (9%) and secondary aerosol formation (8%) are the major contributors to PM 2.5 levels in the city.

    Introduction: Acceptance rate of postpartum intrauterine contraceptive device (PPIUCD) offered through a public health approach is unknown. Our aim was to describe the acceptance rate, expulsion, and follow-up and factors associated with it when PPIUCD was offered to women delivering at two primary health centers (PHCs). Methods: We analyzed routine health data of deliveries at two PHCs in district Faridabad, India between May and December 2014, having sociodemographic variables, obstetric history, and during the follow-up check-up at 6-weeks postpartum for in situ status of intrauterine contraceptive device, side effects, and complications. Results: The overall acceptance rate among those eligible for PPIUCD was 39% (95% confidence interval [CI]: 35.1–42.9). Independent predictor of acceptance was a monthly family income of 25 years (O.R.: 2.21, 95% CI: 1.03–4.73), gravida ≥4 (O.R.: 4.01, 95% CI: 1.28–12.56), and a living previous-child (O.R.: 1.51, 95% CI: 1.04–2.19). Conclusion: Acceptance rate of PPIUCD was higher than that reported in literature. Women from lower income family, having at least one living child, and having attended antenatal care clinic were more likely to accept PPIUCD. PMID:28348988

    Background & objectives: Standard of care for chronic hepatitis C (CHC) in India is peginterferon and ribavirin (RBV). The response to treatment in real life stetting is unclear. The objectives of this study were to evaluate the demographic profile and assess the virological response and predictors of response in CHC patients. Methods: Consecutive patients with CHC were included in this study. Detailed clinical history, risk factors, and predictive factors of response were noted. Patients were treated with peginterferon α2b (1.5 µg/kg/wk) and RBV (12 mg/kg/day) for 6 to 18 months based on response. Results: A total of 211 patients were included in the analysis, mean age 40.6±12.3 yr, 144 (68%) were males and 71 (34%) had compensated cirrhosis. Commonest risk factor for acquiring CHC was previous transfusion and surgery (51%). Genotype 3 (72%) was most common followed by genotype 1 (23%). Overall sustained virologic response (SVR) was 64 per cent [95% CI 57.1%-70.4%]. The SVR was 66.5 per cent [95% CI 58.34-73.89%] for genotype 3 and 61.2 per cent [95% CI 46.23 to 74.80%] for genotype 1. Non-cirrhotics had better SVR rates compared to cirrhotics (76 vs 41%, P<0.001). On multivariate analysis, BMI ≥23 kg/m2, HOMA-IR ≥2, compliance (≤80%), and fibrosis >2 were predictors of low SVR. Interpretation & conclusions: Genotype 3 was the commonest HCV genotype. The commonest source of infection was previous transfusion and surgery. SVR rates for genotypes 3 were better than genotype 1 patients. Predictors of non-response were high BMI, insulin resistance, significant fibrosis and inadequate compliance. PMID:27241647

    Background A high prevalence of gallbladder diseases (GBD) in Northern India warranted a population survey into environmental risk factors. Methods In 60 villages of Uttar Pradesh and Bihar from 13 334 households, 22 861 persons aged >30 years were interviewed for symptoms of GBD, diet and environmental factors. Subsequently ultrasonography (US) was performed in 5100 and 1448 people with and without symptoms, respectively. Heavy metal and pesticide content in soil and water were estimated. Results US revealed a prevalence of GBD of 6.20%. GBD was more common in 5100 persons with symptoms (7.12%) compared with 1448 without (2.99%) (P < 0.05). Adjusted odds ratio (ORs) [95% confidence interval (CI)] revealed a significantly increased risk of GBD in females >50, 1.703 (CI 1.292–2.245); multiparity 1.862 (CI 1.306–2.655) and a genetic history 1.564 (CI 1.049–2.334). An increased risk noted in males with diabetes was 4.271 (CI 2.130–8.566), chickpea consumption 2.546 (CI 1.563–4.146) and drinking unsafe water 3.835 (CI 2.368–6.209). Prevalence of gallstones was 4.15%; more in females 5.59% than males 1.99% (P < 0.05). Cluster analysis identified a positive correlation of nickel, cadmium and chromium in water with a high prevalence of GBD in adjacent villages in Vaishali district, Bihar. Conclusion A high risk of GBD was observed in older, multiparous women and men with diabetes, intake of chickpeas, unsafe water and villages with heavy metal water pollution. PMID:21241429

    Introduction: The US Centers for Disease Control and Prevention (USDHHS-CDC 1996) revealed that the outbreaks of food borne diseases include inadequate cooking, heating, or re-heating of foods consumption of food from unsafe sources, cooling food inappropriately and allowing too much of a time lapse. As we all know that the food handlers have been working in various types of community kitchen and their health status can affect the status of food hygiene which can lead to contamination of foods attributing to acute gastroenteritis and food poisoning in various subgroups of the population e.g., medical/dental/nursing students. The background characteristics of these food handlers may have important role to affect health status of these handlers. Methods: The indexed study was carried out among the food handlers working in the food establishments the 5 teaching hospitals of Bareilly city in U.P. India during one year i.e., from August 2013 to July 2014. The survey method using schedule was conducted to get information about the background characteristics and food handlers and each food handler was examined clinically for assessing health status. Chi-Square test was used as test of significance and regression analysis was also done to nullifying the effect of confounders. Results: The health status of the mess workers was found to be significantly associated with use of gloves, hand washing after toilet and hand washing before cooking and serving food. Conclusion: The rationale of this study was that though many studies have been carried out to show the health status of the food handlers and their background characteristics, no study has highlighted the association of these background characteristics and personal hygiene practices with the health status of food handlers.

    A successful protocol for long-term conservation of two endangered plants viz. Mantisia spathulata and M. wengeri has been devised through cryopreservation of immature seeds. Immature seeds of both the species were precultured in 0.6 M Sucrose and 2 M Glycerol for 3 h at 24 ± 2 degree C. Precultured seeds were then desiccated under the airflow of 27 ± 3 m min -1 velocity inside laminar air flow cabinet for different time periods. The seeds were then cryostored in liquid nitrogen for an hour. A maximum of 40 percent and 36.6 percent seed germination was recorded after cryostorage at moisture contents of 26.0 percent and 16.2 percent for M. spathulata and M. wengeri respectively. To protect these rare plants against loss due to disease, insect damage, or natural disaster a back up collection has been established using the protocol and applied to a large number of immature seeds that were obtained from the ex situ plants growing in the experimental garden of the North-eastern Hill University, Shillong.

    Genetic contributions towards Type 2 diabetes (T2D) have been assessed through association studies across different world populations with inconsistencies. The majority of the T2D susceptibility loci are common across different races or populations but show ethnicity-specific differences. The pathogenesis of T2D involves genetic variants in the candidate genes. The interactions between the genes involved in insulin signaling and secretory pathways are believed to play an important role in determining an individual's susceptibility towards T2D. Therefore, the present study was initiated to examine the differences, if any, in the contribution of polymorphisms towards T2D susceptibility in the background of different ethnic specifications. The present case-control study included a total of 1216 T2D cases and healthy controls from three ethnic groups (Jat Sikhs, Banias and Brahmins) of North-West India. Polymorphisms were selected on the basis of information available in the literature for INS (rs689), INSR (rs1799816) and PP1G.G (rs1799999) in context to T2D. The genotyping was done using PCR-RFLP method. Statistical analysis was done using SPSS 16.0. The analyses revealed that INS (rs689) polymorphism conferred risk towards T2D susceptibility in all the three ethnic groups whereas INSR (rs1799816) polymorphism conferred risk towards T2D in Brahmins only and PP1G.G (rs1799999) polymorphism indicated T2D risk in Jat Sikhs only. Furthermore, interaction analyses indicated the cumulative role of three genetic variants in modulating T2D susceptibility in the three ethnic groups. In conclusion, our results substantiated the evidences for the role of ethnicity in differential susceptibility to T2D in the background of same genetic variants.

    In quartz-free Fe, Na-poor and high-Mg, Al schists from the Bundelkhand craton in north central India, corundum porphyroblasts in finely interleaved phlogopite-chlorite aggregates with rare clinozoisite are mantled by fine-grained (<3 μm) intergrowths of outer collars (>200 μm wide) of phengitic-muscovite and chlorite (phlogopite + corundum + H2O → phengitic-muscovite + chlorite), and <100 μm wide inner collars of margarite-muscovite (corundum + clinozoisite + phengitic muscovite → margarite + muscovite + H2O). Wide-beam electron probe microanalyses indicate Mg in the bi-layered corona increases from corundum outwards, with a complementary decrease in Al and K. Si and Ca increase and then decrease to matrix values. The sharp chemical gradients across the highly structured bi-layered corona are inferred to suggest that the corona-forming reactions were promoted by local grain-boundary-controlled thermodynamic instability as opposed to element transport by advective diffusion. The P-T convergence of KMASH reactions and NCKMASH pseudosection phase relations computed using micro-domain compositions indicate the chlorite-phengitic muscovite outer collar formed at 18-20 kbar and ca. 630°C. The NCKMASH margarite-muscovite inner collar yielded lower metamorphic P-T conditions of 11 ± 3 kbar, ca. 630°C. U-Th-Pb chemical dating of metamorphic monazite and LA-ICPMS U-Pb isotope dating of re-equilibrated zircon yield ca. 2.78 Ga ages, which are interpreted to date corona formation and Neoarchean high-P metamorphism in the Bundelkhand craton, hitherto unknown in the Indian Precambrian.

    Objective: Diabetes has gradually emerged as one of the most serious public health problems in our country. This underlines the need for timely disease detection and decisive therapeutic intervention. This prospective cross-sectional observational study aims at analyzing the utilization pattern of antidiabetic agents in a remote North-East Indian tertiary care teaching hospital in the perspective of current standard treatment guidelines. Materials and Methods: Diabetic patients receiving antidiabetic medication, both as outpatients and inpatients in our hospital over a period of 12 months (May 2013–May 2014), were included in this study. The data obtained were sorted and analyzed on the basis of gender, type of therapy, and hospital setting. Results: A total of 310 patients were included in the study. Metformin was the single most frequently prescribed antidiabetic agent (66.8%) followed by the sulfonylureas group (37.4%). Insulin was prescribed in 23.2% of the patients. Combination antidiabetic drug therapy (65.1%) was used more frequently than monotherapy (34.8%). The use of biguanides (P < 0.0001) and sulfonylureas (P = 0.02) in combination was significant as compared to their use as monotherapy. A total of 48% of all antidiabetic combinations used, comprised metformin and sulfonylureas (n = 96). Insulin use was significantly higher as monotherapy and in inpatients (P < 0.0001). The utilization of drugs from the National List of Essential Medicines was 51.2%, while 11% of antidiabetics were prescribed by generic name. Conclusion: The pattern of utilization largely conforms to the current standard treatment guidelines. Increased use of generic drugs is an area with scope for improvement. PMID:27413351

    Purpose To analyze the adverse obstetrical and perinatal outcome of adolescent mothers associated with first birth. Patients and methods This prospective case-control study was conducted in a tertiary care teaching hospital of North-East India between January 2014 and December 2014. All adolescent primigravidae completing 28 weeks of gestation with singleton pregnancy and delivered at our institution were included in the study group. Primigravidae aged between 20 and 25 years were taken as a control group. Mothers having pregnancy complicated with diabetes mellitus, renal disorder, thyroid disorders, and cardiac diseases were excluded from the study. Demographic data, maternal complications like severe anemia, pre-eclampsia, eclampsia, gestational age at delivery, mode of delivery, and postpartum complications were compared. Among fetal complications, low-birth weight, preterm birth, neonatal intensive care unit admission, still birth, and early neonatal death were compared. All the patients were interviewed regarding contraceptive knowledge and its use preceding the pregnancy. Results Quality antenatal care was received by 80.6% of adolescent mothers. The adolescent mothers had a higher incidence of pre-eclampsia (odds ratio [OR] 2.017 95% confidence interval [CI]: 1.045–3.894, P=0.03), preterm deliveries (OR: 1.655, 95% CI: 1.039–2.636, P=0.03). Among fetal outcomes, the low- birth weight babies (OR: 1.59, 95% CI: 1.016–2.478), low mean birth weight (2,544.4±622.09 g versus 2,701.6±582.51 g), and higher admission to neonatal intensive care unit (OR: 1.957, 95% CI: 1.120–3.417) were significantly associated with adolescent mothers. There was no significant difference found regarding the mode of delivery, still birth, and early neonatal death. Moreover, contraceptive knowledge and its use were found to be poor among adolescent mothers. Conclusion With quality antenatal, intranatal, and postnatal care, the obstetric risk of childbirth in adolescent mothers

    The north-eastern region of India is reported to be the center of origin and rich in diversity of Citrus (L.) species, where some wild and endangered species namely Citrus indica, Citrus macroptera, Citrus latipes, Citrus ichagensis and Citrus assamensis exist in their natural and undisturbed habitat. In order to have comprehensive information about the extent of genetic variability and the occurrence of cryptic genomic hybridity between and within various Citrus species, a combined approach involving morphological, cytogenetical and molecular approaches were adopted in the present study. Cytogenetic approaches are known to resolve taxonomic riddles in a more efficient manner, by clearly delineating taxa at species and sub species levels. Male meiotic studies revealed a gametic chromosome number of n = 9, without any evidence of numerical variations. Bivalents outnumbered all other types of associations in pollen mother cells (PMCs) analyzed at diplotene, diakinesis and metaphase I. Univalents were frequently encountered in nine species presently studied, though their presence appropriately did not influence the distributional pattern of the chromosomes at anaphases I and II. The molecular approaches for phylogenetic analysis based on sequence data related to ITS 1, ITS 2 and ITS 1 + 5.8 s + ITS 2 of rDNA using maximum parsimony method and Bayesian inference have thrown light on species inter-relationship and evolution of Citrus species confirming our cytogenetical interpretations. The three true basic species i.e. Citrus medica, Citrus maxima and Citrus reticulata with their unique status have been resolved into distinct clades with molecular approaches as well. C. indica which occupies a unique position in the phylogenetic ladder of the genus Citrus has been resolved as a distinct clade and almost behaving as an out-group. The presences of quadrivalents in C. indica also echo and support its unique position. From our study it is amply clear that C

    11-β hydroxysteroid dehydrogenase (11-βHSD1), tumor necrosis factor-α (TNF-α) and their role in obesity, regional adiposity and insulin resistance has been sparsely evaluated. We determined the polymorphic status of 11-βHSD1 4478T>G and TNF-α-308G>A in Asian Indians in north India. In this cross-sectional study (n = 498; 258 males, 240 females), association of genotypes (PCR–RFLP) of 11-βHSD1 and TNF-α were analyzed with obesity [BMI ≥ 25 kg/m(2), percentage body fat (%BF by DEXA); subcutaneous and intra-abdominal fat area (L(2-3) level by single slice MRI) in a sub sample] and insulin resistance. 46 percent subjects had generalized obesity, 55 % abdominal obesity and 23.8 % were insulin resistant. Frequencies (%) of [T/T] and [T/G] genotypes of 11-βHSD1 were 89.57 and 10.43 respectively. Homozygosity for 11-βHSD1 4478G/G was absent with no association with parameters of obesity and insulin resistance. Frequencies (%) of TNF-α [G] and [A] alleles were 88 and 12 respectively. Higher frequency of variant -308[A/A] was observed in females versus males (p = 0.01). Females with at least one single A allele of TNF-α-308G>A had significantly high %BF and total skinfold, whereas higher values of waist hip ratio, total cholesterol, triglycerides and VLDL were observed in males. Subjects with even a single A allele in TNF-α genotype showed higher subscapular skinfold predisposing them to truncal subcutaneous adiposity (p = 0.02). Our findings of association of TNF-α-308G>A variant in females with obesity indices suggests a gender-specific role of this polymorphism in obesity. High truncal subcutaneous adiposity is associated with A allele of TNF-α-308G>A in this population.

    The phenotypes and gene frequencies of 3 blood groups, 7 red-cell enzymes and a serum protein were studied in 4 caste population groups of Haryana, North India. The results indicate that the distribution of these blood markers is rather homogeneous in the 4 groups and generally resembles that observed in various populations from neighbouring North Indian states.

    Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the ‘big four’ that includes Cobra, Krait, Russel's viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e.g. Saw scaled vipers in Rajasthan. We reviewed the published literature from various parts of India and found that there is a North-South divide in the snake bite profile from India. Neurotoxic envenomations are significantly higher in North India compared to South India where Hematotoxic envenomations are prevalent. Russel's viper causes local necrosis, gangrene and compartment syndrome. These manifestations have never been reported in North Indian snake bite profile in the published literature. Early morning neuroparalysis caused by Krait is a common problem in North India leading to high mortality after snake bite. This review presents supporting evidence for the North-South divide and proposes a way forward in formulation and revision of guidelines for snake bite in India. PMID:27904261

    Formerly known as Bombay, the city of Mumbai is situated on India's west coast, on the Arabian Sea, roughly 500 km (310 miles) south of the Tropic of Cancer. Its large harbor and ideal location facing Africa, Europe, and the Middle East make it an excellent city for trade. Sometimes referred to as the 'Gateway of India,' Mumbai handles more than one third of the country's foreign trade. The city supports a population of more than 12 million people in an area of roughly 619 square km (239 square miles). The port was acquired in 1534 by Portugal, which named it Bom Bahia, meaning 'beautiful bay.' Originally, the city rested upon seven small islands, mostly basaltic bedrock from earlier lava flows. These islands are now connected to one another by reclaimed land, but each island, or neighborhood, still retains a distinct identity within the city. (For more details, visit Welcome to Bombay: The Gateway of India.) The blue-grey pixels in this false-color image are urban areas. The dark green areas are heavily vegetated surfaces while the light brown regions are more sparsely vegetated. This image of Mumbai was acquired by the Enhanced Thematic Mapper plus (ETM+), flying aboard the Landsat 7 satellite. July 23, 2002, marks the 30th anniversary of the Landsat program.

    This study describes the geochemical distribution of lead (Pb) and identifies the critical factors that significantly control Pb distribution and speciation in coastal and estuarine sediments around India by using published data from the literature. Crustal sources influence the abundance of Pb in coastal sediment from the south-east and central-west coast of India. Parts of north-east, north-west, and south-west coast of India were polluted by Pb. Distribution of Pb in sediments, from the north-east and north-west coasts of India, were controlled by Fe-Mn oxyhydroxide mineral phases of the sediments. However, organic carbon (OC) seemed to be a dominant factor in controlling the distribution of Pb in sediments from the central-east and south-west coasts of India. The outcome of this study may help in decision-making to predict the levels of Pb from natural and anthropogenic sources and to control Pb pollution in coastal and estuarine sediments around India.

    We examined the spatial distribution pattern of reptiles in an eastern Himalayan elevation gradient. The factors governing the distribution have been assessed with emphasis on the mid-domain effect. We surveyed reptiles along the elevation gradient (300-4800 m) of the Teesta valley in Sikkim, Eastern Himalaya, India using time constrained visual encounter survey. A total of 42 species of reptiles were observed during the study, and the species richness peaked at 500-1000 m with no species beyond 3000 m. The observed pattern was consistent with estimated richness, both showing significant negative relation with elevation. Lizards showed a linear decline with elevation, whereas snakes followed a non-linear relation with peak at 500-1000 m. Observed species richness deviated significantly from that predicted by a mid-domain null model. The regression between empirical and simulated richness was not significant for total reptiles as well as lizards and snakes separately. Most species distributed in the high elevation extended towards lower elevation, but low elevation species (around 50%) were restricted below 1000 m. Deviation of empirical from predicted richness indicates that the distributions of reptile species were least governed by geographic hard boundaries. Climatic factors especially temperature explained much variation of reptiles along the Himalayan elevation gradient. Most reptiles were narrowly distributed, especially those found in low elevation indicating the importance of tropical low-land forests in the conservation of reptiles in Eastern Himalayas.

    2010-01-01

    This article explores the relationship between kinship institutions and sex ratios in India at the turn of the twentieth century. Because kinship rules vary by caste, language, religion, and region, we construct sex ratios by these categories at the district level by using data from the 1901 Census of India for Punjab (North), Bengal (East), and Madras (South). We find that the male-to-female sex ratio varied positively with caste rank, fell as one moved from the North to the East and then to the South, was higher for Hindus than for Muslims, and was higher for northern Indo-Aryan speakers than for the southern Dravidian-speaking people. We argue that these systematic patterns in the data are consistent with variations in the institution of family, kinship, and inheritance. PMID:21308567

  17. Molecular epidemiology of rotaviruses in India.

    2003-08-01

    Rotaviruses cause an estimated 140 million cases of gastroenteritis and 800,000 deaths in children between the ages of 6 months to 2 yr in developing countries. In India, one of every 250 children or about 100-150,000 children die of rotavirus diarrhoea each year. The prevalence of rotavirus diarrhoea in India has been found to vary from 5-71 per cent in hospitalized children <5 yr of age with acute gastroenteritis. The seasonal variation of rotavirus diarrhoea in India varies in different geographical regions with high incidence in winter months at low relative humidity in north India. The distinctive features of rotavirus infection in India include the occurrence of severe disease at an early age and common neonatal rotavirus infections which are often asymptomatic. Rotavirus shows genetic and antigenic diversity in terms of subgroup, electropherotypes and G and P serotypes/genotypes. There are a few studies in terms of prevalence of different antigenic and genetic variants from various regions of India. In most studies on subgroup distribution from India a higher prevalence of subgroup II was reported compared to subgroup I. Electropherotyping has also demonstrated that a number of multiple electropherotypes co-circulate at one time in a particular community leading to extensive genomic variation and the appearance of new strains which may become the predominant electropherotype during the peak season. The most common G types reported from India are G1 and G2 and P types are P[4] and P[8]. A significant number of children also have mixed rotavirus infections. G9 strains are also quite commonly seen in Indian children. In addition P6 strains of probable bovine origin have been reported from India. A novel neonatal strain P type 11 human rotavirus (116 E) was isolated from neonates in Delhi, the VP4 of which was closely related to the bovine serotype G10P[11] strain B223 and VP7 was closely related to the human serotype G9 strain. Another neonatal strain G10P[11

    Background: Evaluation of outcomes can help improve the quality of provision of services within a healthcare setting. There is limited report on patient satisfaction in private-sector in India although they provide three-quarters of healthcare services. Aim: The study was designed to report the level of satisfaction among inpatients of a private tertiary care hospital in India. Materials and Methods: A total of 102 participants were recruited and their socio-demographic, health-seeking behavior, and satisfaction rating on various aspects of healthcare were elicited. A five item Likert scale was used to obtain the satisfaction rating. Data analysis was done with the help of Stata version-9. Proportions for the discrete variables and means with Standard Deviation for the continuous variables were obtained. Results: All the participants were urban and from upper-middle or upper socio-economic strata. The participants reported a high level of overall satisfaction (93%) as well as high satisfaction with physicians (95%), the doctor's interpersonal skills (99%), nursing-care (93%), general services (94%), and pharmacy (88.1%). Conclusion: There was a high level of satisfaction reported by the participants at this tertiary level hospital. This might reflect the actual good quality services being provided by the provider or the nonannoying response, which cannot be ruled out. PMID:23050252

    The occurrence of exceptionally heavy rainfall events and associated flash floods in many areas during recent years motivate us to study long-term changes in extreme rainfall over India. The analysis of the frequency of rainy days, rain days and heavy rainfall days as well as one-day extreme rainfall and return period has been carried out in this study to observe the impact of climate change on extreme rainfall events and flood risk in India. The frequency of heavy rainfall events are decreasing in major parts of central and north India while they are increasing in peninsular, east and north east India. The study tries to bring out some of the interesting findings which are very useful for hydrological planning and disaster managements. Extreme rainfall and flood risk are increasing significantly in the country except some parts of central India.

    This bottom-up modeling study, supported by emission inventories and crop production, simulates ozone on local to regional scales. It quantifies, for the first time, potential impact of ozone on district-wise cotton, soybeans, rice, and wheat crops in India for the first decade of the 21st century. Wheat is the most impacted crop with losses of 3.5 ± 0.8 million tons (Mt), followed by rice at 2.1 ± 0.8 Mt, with the losses concentrated in central and north India. On the national scale, this loss is about 9.2% of the cereals required every year (61.2 Mt) under the provision of the recently implemented National Food Security Bill (in 2013) by the Government of India. The nationally aggregated yield loss is sufficient to feed about 94 million people living below poverty line in India.

    Cenozoic convergence between the Indian and Asian plates pro- duced the archetypical continental collision zone comprising the Himalaya mountain belt and the Tibetan Plateau. How and where India-Asia convergence was accommodated after collision at or before 52 Ma remains a long-standing controversy. Since 52 Ma, the two plates have converged up to 3,600 +/- 35 km, yet the upper crustal shortening documented from the geological record of Asia and the Himalaya is up to approximately 2,350-km less. Here we show that the discrepancy between the convergence and the shortening can be explained by subduction of highly extended continental and oceanic Indian lithosphere within the Himalaya be- tween approximately 50 and 25 Ma. Paleomagnetic data show that this extended continental and oceanic "Greater India" promontory resulted from 2,675 +/- 700 km of North-South extension between 120 and 70 Ma, accommodated between the Tibetan Himalaya and cratonic India. We suggest that the approximately 50 Ma "India"- Asia collision was a collision of a Tibetan-Himalayan microcontinent with Asia, followed by subduction of the largely oceanic Greater India Basin along a subduction zone at the location of the Greater Himalaya. The "hard" India-Asia collision with thicker and contiguous Indian continental lithosphere occurred around 25-20 Ma. This hard collision is coincident with far-field deformation in central Asia and rapid exhumation of Greater Himalaya crystalline rocks, and may be linked to intensification of the Asian monsoon system. This two-stage collision between India and Asia is also reflected in the deep mantle remnants of subduction imaged with seismic tomography.

    New geochronological and geochemical data on magmatic activity from the India-Asia collision zone enables recognition of a distinct magmatic flare-up event that we ascribe to slab breakoff. This tie-point in the collisional record can be used to back-date to the time of initial impingement of the Indian continent with the Asian margin. Continental arc magmatism in southern Tibet during 80–40 Ma migrated from south to north and then back to south with significant mantle input at 70–43 Ma. A pronounced flare up in magmatic intensity (including ignimbrite and mafic rock) at ca. 52–51 Ma corresponds to a sudden decrease in the India-Asia convergence rate. Geological and geochemical data are consistent with mantle input controlled by slab rollback from ca. 70 Ma and slab breakoff at ca. 53 Ma. We propose that the slowdown of the Indian plate at ca. 51 Ma is largely the consequence of slab breakoff of the subducting Neo-Tethyan oceanic lithosphere, rather than the onset of the India-Asia collision as traditionally interpreted, implying that the initial India-Asia collision commenced earlier, likely at ca. 55 Ma.

    A survey of Indian medical historiography will reveal no dearth of work on the systems of medicine and medical literature of ancient India. However, the people who were responsible for the healing have not received much attention. This article traces the evolution of the physician as a professional in ancient India. This article reviews the secondary literature on healing and medical practice in India, specifically pertaining to the individual medical practitioner, drawing from varied sources. The healers of ancient India hailed from different castes and classes. They were well-respected and enjoyed state patronage. They were held to the highest ethical standards of the day and were bound by a strict code of conduct. They underwent rigorous training in both medicine and surgery. Most physicians were multi-skilled generalists, and expected to be skilled in elocution and debate. They were reasonably well-off financially. The paper also briefly traces the evolution of medicinal ideas in ancient India. PMID:27843823

  12. Origin and Distribution Of Glacial Lakes: A Case Study In Tista Basin, India

    2015-12-01

    Himalayan glaciers are experiencing retreat due to changes in the temperature and precipitation pattern. Retreating glaciers depending upon the underlying bed topography can cause lake formation near terminus. Therefore formation and draining of lakes in the glaciated terrain of Himalaya is commonly observed. However, few lakes became stable under suitable geomorphologic conditions and grow sufficiently large to threaten population and infrastructure in downstream. In this investigation changes in glacial lakes in Tista basin were studied using satellite images for a period between 1989 and 2010. The Tista basin in Sikkim covers approximately 7096 sq km area and the total glaciated area is 501± 29 sq km. During the period of investigation the lake area is increased from 6.6 ± 0.8 km2 to 9.6 ± 1.1 km2 due to formation of new lakes and also due to expansion of existing lake. Out of 23 lakes, 16 showed variable increase in area. We have also observed formation of stable proglacial lake due to coalescence of small supra glacial lakes on Changsang and South Lhonak Glacier. The size of lake near South Lhonak Glacier was increased from 18 to 126 ha from 1978 to 2014 (Figure). Therefore detail field investigations were carried out to understand volume and extent of ice in end moraine. The water volume was estimated as 53 million m3 using bathymetric survey and ice at the core of terminal moraines was mapped using resistivity survey. These investigations suggests a possibility of catastrophic outburst flood, if moraine dam breached under extreme weather conditions. Therefore, mitigation strategy is needed to improve safety of people living in the region. In addition, numerous remote sensing based investigations have mapped more than 300 lakes in the glaciated terrain in India, therefore, a national program to monitor glacier lakes and strategy to mitigate possible disaster is needed.

    Background Interferon-based antiviral therapy is offered only to those HCV patients who have either chronic hepatitis or early cirrhosis. Advanced cirrhotics do not tolerate interferon-based therapy. Since HCV is asymptomatic in early stages and usually presents late, the eligibility for interferon-based therapy is thus limited. There are scarce studies from India, which looked specifically the eligibility of interferon-based therapy in HCV patients. Aim To study the spectrum of presentation of HCV infection, determine their eligibility for interferon-based therapy, and follow for SVR. Methods The records of all consecutive patients of HCV, >14 years age, who presented to our department between 2008 and 2014, were analyzed for categorization into chronic hepatitis, cirrhosis and hepatocellular carcinoma. Patients with detectable HCV RNA who have chronic hepatitis or Child A cirrhosis were considered eligible for Peg-interferon and ribavirin. Patients who received treatment were followed for SVR. Results 777 patients (median age 49 [range 15–95] years, males 69%) were included. Cirrhosis was the most common presentation (56%, 439/777) followed by chronic hepatitis (37%, 287/777) and HCC (7%, 51/777). Of patients who had cirrhosis (including those with HCC), 36% (174/490) were Child A; 51% (250/490) were Child B and 14% (66/490) were Child C. Only 347/777 (45%) were eligible for Peg-interferon-alpha and Ribavirin. Among the remaining 430 patients, in 326 (76%) the disease was far too advanced. Of eligible patients only 54% actually received Peg-interferon-alpha and Ribavirin and 81% patients could complete the course. Of them only 70% could achieve SVR. Conclusions Most HCV patients in India present late and only about 45% are eligible for Interferon-based antiviral treatment. At presentation 56% patients already have cirrhosis and 7% have HCC. Since HCV is usually asymptomatic in early stages, awareness about screening should be increased so that more patients are

    Purpose To describe the prevalence of cataract in older people in 2 areas of north and south India. Design Population-based, cross-sectional study. Participants Randomly sampled villages were enumerated to identify people aged ≥60 years. Of 7518 enumerated people, 78% participated in a hospital-based ophthalmic examination. Methods The examination included visual acuity measurement, dilatation, and anterior and posterior segment examination. Digital images of the lens were taken and graded by type and severity of opacity using the Lens Opacity Classification System III (LOCS III). Main Outcome Measures Age- and gender-standardized prevalence of cataract and 95% confidence intervals (CIs). We defined type of cataract based on the LOCS III grade in the worse eye of: ≥4 for nuclear cataract, ≥3 for cortical cataract, and ≥2 for posterior subcapsular cataract (PSC). Any unoperated cataract was based on these criteria or ungradable dense opacities. Any cataract was defined as any unoperated or operated cataract. Results The prevalence of unoperated cataract in people aged ≥60 was 58% in north India (95% CI, 56–60) and 53% (95% CI, 51–55) in south India (P = 0.01). Nuclear cataract was the most common type: 48% (95% CI, 46–50) in north India and 38% (95% CI, 37–40) in south India (P<0.0001); corresponding figures for PSC were 21% (95% CI, 20–23) and 17% (95% CI, 16–19; P = 0.003), respectively, and for cortical cataract 7.6% (95% CI, 7–9) and 10.2% (95% CI, 9–11; P<0.004). Bilateral aphakia/pseudophakia was slightly higher in the south (15.5%) than in the north (13.2%; P<0.03). The prevalence of any cataracts was similar in north (73.8%) and south India (71.8%). The prevalence of unoperated cataract increased with age and was higher in women than men (odds ratio [OR], 1.8). Aphakia/pseudophakia was also more common in women, either unilateral (OR, 1.2; P<0.02) or bilateral (OR, 1.3; P<0.002). Conclusions We found high rates of unoperated

    Background: The human immunodeficiency virus (HIV) infection which manifests as acquired immunodeficiency syndrome (AIDS) is a disease involving the defects of the T-lymphocyte arm of the immune system. Certain laboratory parameters such as the cluster of differentiation (CD4) count and clinical parameters have long been used as markers of disease progression. In industrialized countries, many studies show a highly correlation between the incidence of oral lesions and immunosuppression and hence, can be used as a marker of immunosuppression. This might not be applicable to a developing country like India. In this study, efforts have been made to supplement the present knowledge on various aspects of oral manifestations in HIV patients in the Indian subcontinent. Aims: To correlate the oral manifestations in HIV/AIDS patients to the level of circulating CD4+ T-lymphocyte count and their effect in anti-retroviral therapy (ART). Subjects and Methods: A total of 104 HIV positive patients were examined for oral lesions. The CD4 count estimated on the same day by fluorescent activated cell sort count machine was then correlated with various oral lesions. Results: Oral manifestations appeared when CD4 count decreased below 500 cells/mm3. Moreover, oral lesions found at different stages showed very strong correlation to their respective CD4 count. Furthermore, there was considerable decline in the incidence of oral manifestations in patients undergoing highly active ART. Conclusions: Oral manifestations are highly predictive markers of severe immune deterioration and disease progression in HIV patients. PMID:27994425

    Introduction Overweight and obesity are a public health problem in India not only in adults but also in children. The authors sought to estimate the prevalence of overweight and obesity in school-going children of 6–17 years of age and examine its demographic and dietary correlates in context of their urban-rural status and socio-economic status. Methods In this cross-sectional survey height and weight were measured in 1266 school children in government and private schools of urban and rural areas. Dietary assessment was done using single day 24-hour dietary recall method. The data were analyzed using SPSS (IBM SPSS Statistics Version 19) and WHO AnthroPlus Software. Factorial ANOVA was used for testing interaction within and between subgroups for continuous variables and Chi-square test was used for categorical variables. Results It was found that the overall prevalence of overweight was 15.6% of which 5.4% were obese, with maximum prevalence in boys attending urban private schools. The mean caloric intake in the study population with 24-hour dietary recall method was 1558.2 kilocalories (SD: 428 kilocalories). Conclusion Overweight and obesity is a significant problem in school-going children. Higher socio-economic status continues to remain an important driver of this epidemic in the younger generation and affects demographic and dietary determinants of this problem. PMID:27227780

    India emerged as a free and democratic country in 1947, and entered into the nuclear age in 1948 by establishing the Atomic Energy Commission (AEC), with Homi Bhabha as the chairman. Later on the Department of Atomic Energy (DAE) was created under the Office of the Prime Minister Jawahar Lal Nehru. Initially the AEC and DAE received international cooperation, and by 1963 India had two research reactors and four nuclear power reactors. In spite of the humiliating defeat in the border war by China in 1962 and China's nuclear testing in 1964, India continued to adhere to the peaceful uses of nuclear energy. On May 18, 1974 India performed a 15 kt Peaceful Nuclear Explosion (PNE). The western powers considered it nuclear weapons proliferation and cut off all financial and technical help, even for the production of nuclear power. However, India used existing infrastructure to build nuclear power reactors and exploded both fission and fusion devices on May 11 and 13, 1998. The international community viewed the later activity as a serious road block for the Non-Proliferation Treaty and the Comprehensive Test Ban Treaty; both deemed essential to stop the spread of nuclear weapons. India considers these treaties favoring nuclear states and is prepared to sign if genuine nuclear disarmament is included as an integral part of these treaties.

    Landslides - mass movements of rock, debris or earth down a slope - are worldwide phenomena which cause significant damage and an estimated 5000 fatalities each year. They are caused by the interplay of various natural and anthropogenic factors and occur under diverse geoenvironmental conditions. In India, landslides occur primarily in the Himalayas of North India and in the Western Ghats of South India. This paper reports the results of field investigations for six landslide sites in North, Northeast and South India. We provide explanations as to why several landslides occurred at each of the sites. Our goal is to gain a deeper insight into the causes and precursors of landslides, which will facilitate more accurate identification of landslide-prone locations and enable early detection of landslide events.

    Using a national district-level dataset of India composed of information on investments in primary schooling (data from the District Information Survey for Education [DISE, 2007/8]) and information on demographic characteristics of elected officials (data from the Election Commission of India [ECI, 2000/04]), we examined the relationship between women's representation in State Legislative Assembly (SLA) seats and district-level investments in primary schooling. We used OLS regressions adjusting for confounders and spatial autocorrelation, and estimated separate models for North and South India. Women's representation in general SLA seats typically was negatively associated with investments in primary-school amenities and teachers; women's representation in SLA seats reserved for under-represented minorities, i.e., scheduled castes and scheduled tribes, typically was positively associated with investments in primary schooling, especially in areas addressing the basic needs of poor children. Women legislators' gender and caste identities may shape their decisions about redistributive educational policies.

    1980-01-26

    I read Dr. Rao's article on attitudes to women and nutrition programmes in India (Dec. 22/29, p. 1357) with considerable interest. In India parents have to save a lot of money to be able to give a dowry when a daughter marries. In addition they are expected to spend considerable sums when their daughters' children are born and when the grandchildren in turn marry. The task of looking after elderly parents--and of discharging their responsibilities if they themselves are unable to do so--falls upon the sons. In India daughters rarely help out their parents in this way, and the parents will not usually agree to accept help from daughters if they have a son who is prepared to discharge the sacred duty of helping parents in time of need. Once she marries, a daughter's obligations to her parents cease while their obligations to her extend even further to include her husband, children, and in-laws. No wonder the birth of a girl is rarely a cause of celebration in India. The main cause for the plight of women in India is poverty. In most Indian families, the woman of the house will consume less than anyone of nutritious items such as milk, cheese, meat, fish, and butter. Whenever the family's meagre resources are shared out, whether for food, for education, for medical care, it is the males who are given preference. This unequal distribution takes place with the full approval of the woman of the house. Food is normally allocated by the woman, and when food is scarce they tend to favour sons over daughters. Readers in the West may feel that women get the worst possible deal in India. However, although parents do not normally spend as much on the education of their daughters as they do on their sons, in the long run daughters very often get more than their fair share of the family's fortunes because of the dowry system and other social customs.

They offer a number of different training programmes, from 1 day to 6 months. The council is developing a core curriculum for teaching bioethics, which would be applied uniformly in medical schools throughout the country. Drug development and ethics is also important in India, particularly now that the local pharmaceutical industry is expanding and so many drugs trials are outsourced to the country. The council is also very active in encouraging the development of ethics review committees.

    The practice of medical and surgical measures in the management of urological ailments prevailed in ancient India from the Vedic era around 3000 BC. Subsequently in the Samhita period, the two stalwarts - Charaka in medicine and Susruta in surgery elevated the art of medicine in India to unprecedented heights. Their elaboration of the etiopathological hypothesis and the medical and surgical treatments of various urological disorders of unparalleled ingenuity still remain valid to some extent in our contemporary understanding. The new generation of accomplished Indian urologists should humbly venerate the legacy of the illustrious pioneers in urology of our motherland. PMID:19675749

  11. The trajectory of India towards Eurasia recorded by subducted slabs: evidence for southward subduction of the Tethys Ocean under India after 130 Ma

    At the ~130 Ma breakup of India from Australia-Antarctica, published paleomagnetic data estimate that India was located south of 30°S. As India began its northward journey that continues today, the 5000 km of Tethys Ocean that stood in the expanse between India and Eurasia gradually disappeared, leaving only traces of its existence in ophiolite sutures and accreted terranes at the Himalayas, the largest orogeny on Earth today. Here we present newly mapped, sub-horizontal slabs under the Indian Ocean at depths of 1600 to 2100 km and at latitudes between 35°S to 15°N. These slabs are further south than any published paleolatitudinal estimates of initial India-Asia collision and thus, the existence of these slabs cannot be explained by the popular idea of northward Tethys subduction under Eurasia. Instead, our slab constraints show for the first time that the majority of the Tethys Ocean was subducted southward after 130 Ma, overrun by a northward-moving India. When restored to the surface of a spherical model Earth, the slabs closely correspond to the well-known track of India from Eastern Gondwanaland to Eurasia that began at ~130 Ma, viewed in a mantle reference. We present a plate reconstruction that includes other restored slabs from the India-Eurasia collision zone, which are at shallower depths and ubiquitously located north of the equator. The reconstruction implies that the Tethys Ocean was subducted under Greater India, India and the post-breakup ocean at the eastern margin of the Indian plate - now identified as the enigmatic 'Burma slab'. Slab geometries were mapped from global P- and S-wave models and restored to the surface of a spherical Earth model. Gplates software was used to reconstruct the mapped slabs.

    2016-01-01

    Non-Hodgkin's lymphoma (NHL) is a common hematological malignancy. The age-adjusted incidence rates for NHL in men and women in India are 2.9/100,000 and 1.5/100,000, respectively. These are about one fourth of the incidence rates reported from Western Europe or North America. Within India, the incidence is several-fold higher in urban cancer registries compared to rural areas; the incidence being higher in metropolitan cities and Indian immigrants suggesting that urban lifestyles and economic progress may increase the cancer incidence. Compared to developed nations, the key differences in the presentation in India include: median age of 54 years (almost a decade less), higher male to female ratio, higher proportion of patients with B-symptoms (40-60 vs. 20-30%), poor ECOG performance status (≥2) at diagnosis (50 vs. 20-30%), higher frequency of diffuse large B-cell lymphomas (60-70 vs. <40%), lower frequency of follicular NHL (<20 vs. 30-40%) and T-cell type in 10-20 vs. <10%. The estimated mortality rate due to NHL is higher in India than in North America and Western Europe. Diagnostic and treatment delays, incorrect diagnosis and inappropriate or suboptimal treatment may be possible reasons for the poor outcome. Any improvement in the outcomes for NHL in India will require a nationwide approach, e.g. creation of several regional and district-level centers with expertise in lymphoma management. Collection of data on patient- and disease-related characteristics, treatment outcome, development of infrastructure, centralized review of histopathology subtype, novel treatment protocols, rigorous follow-up, training of staff, and financial support towards treatment could be possible strategies to improve the outcome.

    Military personnel, because of the unique nature of their duties and services, are likely to be under stress which at times has no parallel in civilian life. The stress of combat and service in extreme weather conditions often act as major stressors. The modern practices in military psychiatry had their beginning during the two World Wars, more particularly, the IInd World War. The GHPU concept had the beginning in India with military hospitals having such establishments in the care of their clientele. As the nation gained independence, many of the military psychiatrists shifted to the civil stream and contributed immensely in the development of modern psychiatry in India. In the recent years military psychiatry has been given the status of a subspecialty chapter and the military psychiatrists have been regularly organizing CMEs and training programs for their members to prepare them to function in the special role of military psychiatrists.

    The term 'medical tourism' is under debate because health care is a serious business and rarely do patients combine the two. India is uniquely placed by virtue of its skilled manpower, common language, diverse medical conditions that doctors deal with, the volume of patients, and a large nonresident Indian population overseas. Medical tourism requires dedicated services to alleviate the anxiety of foreign patients. These include translation, currency conversion, travel, visa, posttreatment care system,and accommodation of patient relatives during and after treatment.

    Dengue virus belongs to family Flaviviridae, having four serotypes that spread by the bite of infected Aedes mosquitoes. It causes a wide spectrum of illness from mild asymptomatic illness to severe fatal dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS). Approximately 2.5 billion people live in dengue-risk regions with about 100 million new cases each year worldwide. The cumulative dengue diseases burden has attained an unprecedented proportion in recent times with sharp increase in the size of human population at risk. Dengue disease presents highly complex pathophysiological, economic and ecologic problems. In India, the first epidemic of clinical dengue-like illness was recorded in Madras (now Chennai) in 1780 and the first virologically proved epidemic of dengue fever (DF) occurred in Calcutta (now Kolkata) and Eastern Coast of India in 1963-1964. During the last 50 years a large number of physicians have treated and described dengue disease in India, but the scientific studies addressing various problems of dengue disease have been carried out at limited number of centres. Achievements of Indian scientists are considerable; however, a lot remain to be achieved for creating an impact. This paper briefly reviews the extent of work done by various groups of scientists in this country. PMID:23041731

    Using the Indian module of the Second Generation Model 9SGM, we explore a reference case and three scenarios in which greenhouse gas emissions were controlled. Two alternative policy instruments (carbon taxes and tradable permits) were analyzed to determine comparative costs of stabilizing emissions at (1) 1990 levels (the 1 X case), (2) two times the 1990 levels (the 2X case), and (3) three times the 1990 levels (the 3X case). The analysis takes into account India`s rapidly growing population and the abundance of coal and biomass relative to other fuels. We also explore the impacts of a global tradable permits market to stabilize global carbon emissions on the Indian economy under the following two emissions allowance allocation methods: (1) {open_quotes}Grandfathered emissions{close_quotes}: emissions allowances are allocated based on 1990 emissions. (2) {open_quotes}Equal per capita emissions{close_quotes}: emissions allowances are allocated based on share of global population. Tradable permits represent a lower cost method to stabilize Indian emissions than carbon taxes, i.e., global action would benefit India more than independent actions.

  5. Tobacco control in India.

    PubMed

    Shimkhada, Riti; Peabody, John W

    2003-01-01

    Legislation to control tobacco use in developing countries has lagged behind the dramatic rise in tobacco consumption. India, the third largest grower of tobacco in the world, amassed 1.7 million disability-adjusted life years (DALYs) in 1990 due to disease and injury attributable to tobacco use in a population where 65% of the men and 38% of the women consume tobacco. India's anti-tobacco legislation, first passed at the national level in 1975, was largely limited to health warnings and proved to be insufficient. In the last decade state legislation has increasingly been used but has lacked uniformity and the multipronged strategies necessary to control demand. A new piece of national legislation, proposed in 2001, represents an advance. It includes the following key demand reduction measures: outlawing smoking in public places; forbidding sale of tobacco to minors; requiring more prominent health warning labels; and banning advertising at sports and cultural events. Despite these measures, the new legislation will not be enough to control the demand for tobacco products in India. The Indian Government must also introduce policies to raise taxes, control smuggling, close advertising loopholes, and create adequate provisions for the enforcement of tobacco control laws.

    Ever since the discovery of the first indigenous case in 1981, paragonimiasis has gained recognition as a significant food borne parasitic zoonosis in India. The data available on the occurrence of paragonimiasis, until today, may be just the tip of an iceberg as the study areas covered were restricted to Northeast Indian States. Nevertheless, the results of research on paragonimiasis in India have revealed valuable information in epidemiology, life cycle, pathobiology and speciation of Indian Paragonimus. Potamiscus manipurensis, Alcomon superciliosum and Maydelliathelphusa lugubris were identified as the crab hosts of Paragonimus. Paragonimus miyazakii manipurinus n. sub sp., P. hueit’ungensis, P. skrjabini, P. heterotremus, P. compactus, and P. westermani have been described from India. P. heterotremus was found as the causative agent of human paragonimiasis. Ingestion of undercooked crabs and raw crab extract was the major mode of infection. Pulmonary paragonimiasis was the commonest clinical manifestation while pleural effusion and subcutaneous nodules were the common extra-pulmonary forms. Clinico-radiological features of pulmonary paragonimiasis simulated pulmonary tuberculosis. Intradermal test, ELISA and Dot-immunogold filtration assay (DIGFA) were used for diagnosis and epidemiological survey of paragonimiasis. Phylogenitically, Indian Paragonimus species, although nested within the respective clade were distantly related to others within the clade. PMID:22960885

    Shigellosis is one of the major causes of diarrhoea in India. The accurate estimates of morbidity and mortality due to shigellosis are lacking, though it is endemic in the country and has been reported to cause many outbreaks. The limited information available indicates Shigella to be an important food-borne pathogen in India. S. flexneri is the most common species, S. sonnei and non-agglutinable shigellae seem to be steadily surfacing, while S. dysenteriae has temporarily disappeared from the northern and eastern regions. Antibiotic-resistant strains of different Shigella species and serotypes have emerged all over the world. Especially important is the global emergence of multidrug resistant shigellae, notably the increasing resistance to third generation cephalosporins and fluoroquinolones, and also azithromycin. This calls for a continuous and strong surveillance of antibiotic resistance across the country for periodic updation of the local antibiograms. The prevention of shigellosis is desirable as it will substantially reduce the morbidity associated with diarrhoea in the country. Public health measures like provision of safe water and adequate sanitation are of immense importance to reduce the burden of shigellosis, however, the provision of resources to develop such an infrastructure in India is a complex issue and will take time to resolve. Thus, the scientific thrust should be focused towards development of a safe and affordable multivalent vaccine. This review is focused upon the epidemiology, disease burden and the therapeutic challenges of shigellosis in Indian perspective. PMID:27487999

    Child maltreatment is a global problem but is more difficult to assess and manage in developing countries such as India where one-fifth of the world's total child population resides. Certain forms of maltreatment such as feticide, infanticide, abandonment, child labour, street-begging, corporal punishment and battered babies are particularly prevalent in India. Most physicians still need to be sensitized in order to suspect child abuse on the basis of unexplained trauma, multiple fractures, parental conflict and other corroborative evidence. This article summarizes the various aspects of this major problem in resource-poor settings in the hope that it will assist in the planning of services addressing child physical and sexual abuse and neglect in India and in other developing countries. A culture of non-violence towards children needs to be built into communities in order to provide an environment conducive to the overall development of the child. Rehabilitation of abused children and their families requires a multi-disciplinary service including paediatricians, child psychologists and social workers, and the training of police forces in how to tackle the problem.

  9. Tobacco control in India.

    Legislation to control tobacco use in developing countries has lagged behind the dramatic rise in tobacco consumption. India, the third largest grower of tobacco in the world, amassed 1.7 million disability-adjusted life years (DALYs) in 1990 due to disease and injury attributable to tobacco use in a population where 65% of the men and 38% of the women consume tobacco. India's anti-tobacco legislation, first passed at the national level in 1975, was largely limited to health warnings and proved to be insufficient. In the last decade state legislation has increasingly been used but has lacked uniformity and the multipronged strategies necessary to control demand. A new piece of national legislation, proposed in 2001, represents an advance. It includes the following key demand reduction measures: outlawing smoking in public places; forbidding sale of tobacco to minors; requiring more prominent health warning labels; and banning advertising at sports and cultural events. Despite these measures, the new legislation will not be enough to control the demand for tobacco products in India. The Indian Government must also introduce policies to raise taxes, control smuggling, close advertising loopholes, and create adequate provisions for the enforcement of tobacco control laws.

    A three-month sabbatical allowed a superficial overview of Indian medical history and practice. As in Western nations, cost is a major determinant of health care delivery in India; poverty and fiscal shortages, however, deny care to many. The education of Indian physicians is similar to that in Western nations and a high level of clinical competence is seen. However, physician compensation is woefully low by Western standards. India possesses its own indigenous medical systems, purported to be the oldest in the world and predating Hippocrates by several millenia. Most Indians are cared for by native practitioners whose medical techniques are intricately related to the Hindu and Islamic religions. Many of their herbal medicines have been assimilated into contemporary Western practice. Diseases unknown to us except by textbooks are commonly seen and effectively treated. On the other hand, Western diseases such as coronary arteriosclerosis are not uncommon in a land of massive overpopulation and malnutrition. The humbling aspect of this experience is the realization that medical practice dating back several millenia can be made more modern and carried out competently by contemporary physicians. A Western physician working in India finds an unparalleled variety of disease in a totally different medical-religious environment allowing him to reorganize his priorities and to rediscover himself in the world within which he lives.

    2015-05-01

    Haemoglobinopathies particularly haemoglobin S and E (HbS, HbE) and β-thalassaemia are important challenges for tribal populations in India. The HbS, HbE and β-thalassaemia genes are variably distributed across various tribal populations of India. HbE is mainly restricted in tribals of North-East, West Bengal, Odisha and those in Andaman and Nicobar islands. HbS has more extensive distribution in the country (10-40% trait frequency) and the homozygotes and double heterozygotes present with a wide array of morbidities. The morbidity varies greatly in different areas of the country due to differential co-inheritance of α-thalassaemia gene and interaction of various epistatic and environmental factors. Though substantial data on prevalence of these disorders exist, there is an urgent need to develop integrated hierarchical core facilities to manage the disease. Such centres will generate more data and will also explore areas of management which need more local attention. Newborn screening, genetic counselling, carrier detection, prenatal diagnosis along with management of cases should form the basic infrastructure of haemoglobinopathy management. Research in this areas should continue focusing on various challenges in care delivery, prevention and basic sciences on interaction of haemoglobinopathies with various other infections.

    A study of menarcheal age was carried out in southern India. A logit method of analysis was applied to status quo data on 1267 Tamil and Telugu speaking girls aged 9 to 18 years in 3 schools catering for different socio-economic groups. There appears to be no relationship of menarcheal age with dietary pattern classified simply as vegetarian and non-vegetarian. Differences in median age at menarche between schools correspond well with the socio-economic differences between them. The median age in the most advantaged school (12-86 years) is comparable with that in recent studies in southern and eastern Europe, and may perhaps be in advance of some recent north-west European samples.

  16. Charnockitic magmatism in southern India

    2004-12-01

    Large charnockite massifs cover a substantial portion of the southern Indian granulite terrain. The older (late Archaean to early Proterozoic) charnockites occur in the northern part and the younger (late Proterozoic) charnockites occur in the southern part of this high-grade terrain. Among these, the older Biligirirangan hill, Shevroy hill and Nilgiri hill massifs are intermediate charnockites, with Pallavaram massif consisting dominantly of felsic charnockites. The charnockite massifs from northern Kerala and Cardamom hill show spatial association of intermediate and felsic charnockites, with the youngest Nagercoil massif consisting of felsic charnockites. Their igneous parentage is evident from a combination of features including field relations, mineralogy, petrography, thermobarometry, as well as distinct chemical features. The southern Indian charnockite massifs show similarity with high-Ba-Sr granitoids, with the tonalitic intermediate charnockites showing similarity with high-Ba-Sr granitoids with low K2O/Na2O ratios, and the felsic charnockites showing similarity with high-Ba-Sr granitoids with high K2O/Na2O ratios. A two-stage model is suggested for the formation of these charnockites. During the first stage there was a period of basalt underplating, with the ponding of alkaline mafic magmas. Partial melting of this mafic lower crust formed the charnockitic magmas. Here emplacement of basalt with low water content would lead to dehydration melting of the lower crust forming intermediate charnockites. Conversely, emplacement of hydrous basalt would result in melting at higher {ie565-01} favoring production of more siliceous felsic charnockites. This model is correlated with two crustal thickening phases in southern India, one related to the accretion of the older crustal blocks on to the Archaean craton to the north and the other probably related to the collision between crustal fragments of East and West Gondwana in a supercontinent framework.

    The depletion of groundwater resources threatens food and water security in India. However, the relative influence of groundwater pumping and climate variability on groundwater availability and storage remains unclear. Here we show from analyses of satellite and local well data spanning the past decade that long-term changes in monsoon precipitation are driving groundwater storage variability in most parts of India either directly by changing recharge or indirectly by changing abstraction. We find that groundwater storage has declined in northern India at the rate of 2 cm yr-1 and increased by 1 to 2 cm yr-1 in southern India between 2002 and 2013. We find that a large fraction of the total variability in groundwater storage in north-central and southern India can be explained by changes in precipitation. Groundwater storage variability in northwestern India can be explained predominantly by variability in abstraction for irrigation, which is in turn influenced by changes in precipitation. Declining precipitation in northern India is linked to Indian Ocean warming, suggesting a previously unrecognized teleconnection between ocean temperatures and groundwater storage.

    The present study deals with spatial and temporal trend analysis of precipitation and temperature (1970-2004) in eastern India. Long-term trend direction and magnitude of change over time (annual and seasonal) were detected and analyzed by Mann-Kendall test, Sen's slope estimator, Least square linear regression, Spearman rank correlation and Sequential Mann-Kendall test. In addition to it, correlation analysis was also performed. Trend analysis of annual rainfall by different methods indicated similar annual trends in eastern India. North-eastern, south-eastern and western parts of eastern India indicated increasing trend, whereas the north-western, central and southern parts showed decreasing trend. A similar trend was observed by different methods in case of seasonal rainfall. During winter season, decreasing trend was observed in the central part, whereas similar results were obtained for pre-and post-monsoon in the western part. The trend during monsoon season was found similar to annual rainfall trend. Abrupt change in trend of rainfall with time was lacking in eastern India. Maximum temperature analysis indicated increasing trend in the western part for all the seasons (except in monsoon) and decreasing trend in the eastern part. On the contrary, increasing trend was observed in the eastern part and decreasing trend in the western half of the study area for all the seasons in case of minimum temperature. Significant changes were observed during monsoon season as compared to other seasons. A decreasing trend in mean temperature was observed in the central, southern and north western parts, whereas it was found to be increasing in the north-eastern, western and south-eastern parts. In majority of the eastern India region, any abrupt change of trend in temperatures with time was not clearly observed. Negative correlation between rainfall and maximum temperature was observed in the entire eastern India. Similar results were observed in case of minimum temperature

    Performances of the state-of-the-art CMIP5 models in reproducing the spatial rainfall patterns over seven homogeneous rainfall zones of India viz. North Mountainous India (NMI), Northwest India (NWI), North Central India (NCI), Northeast India (NEI), West Peninsular India (WPI), East Peninsular India (EPI) and South Peninsular India (SPI) have been assessed using different conventional performance metrics namely spatial correlation (R), index of agreement (d-index), Nash-Sutcliffe efficiency (NSE), Ratio of RMSE to the standard deviation of the observations (RSR) and mean bias (MB). The results based on these indices revealed that majority of the models are unable to reproduce finer-scaled spatial patterns over most of the zones. Thereafter, four bias correction methods i.e. Scaling, Standardized Reconstruction, Empirical Quantile Mapping and Gamma Quantile Mapping have been applied on GCM simulations to enhance the skills of the GCM projections. It has been found that scaling method compared to other three methods shown its better skill in capturing mean spatial patterns. Multi-model ensemble (MME) comprising 25 numbers of better performing bias corrected (Scaled) GCMs, have been considered for developing future rainfall patterns over seven zones. Models' spread from ensemble mean (uncertainty) has been found to be larger in RCP 8.5 than RCP4.5 ensemble. In general, future rainfall projections from RCP 4.5 and RCP 8.5 revealed an increasing rainfall over seven zones during 2020s, 2050s, and 2080s. The maximum increase has been found over southwestern part of NWI (12-30%), northwestern part of WPI (3-30%), southeastern part of NEI (5-18%) and northern and eastern part of SPI (6-24%). However, the contiguous region comprising by the southeastern part of NCI and northeastern part of EPI, may experience slight decreasing rainfall (about 3%) during 2020s whereas the western part of NMI may also receive around 3% reduction in rainfall during both 2050s and 2080s.

    Hemoglobin E (HbE) is one of the world's most common and important mutations. HbE disorders may be found in heterozygous (AE), homozygous (EE) and compound heterozygous state. It is important to distinguish HbE disorders diagnostically because of marked differences in clinical course among different genotypes. To find out whether RBC indices as obtained from automated cell counter can provide a clue to the diagnosis of HbE disease. This study was carried out in the Department of Clinical Pathology, PGIMER, Dr. Ram Manohar Lohia Hospital, New Delhi. It included antenatal pregnant females brought for routine check-up as well as referred patients suspected of having hemoglobinopathies. High Performance liquid chromatography was used as a confirmatory test for identification of hemoglobinopathy. Total 20 cases of subtype homozygous HbE (3), HbE trait (12) and Eβ-thalassemia (5) were identified. Statistical analysis was done to find out correlation between levels of HBA2, HBF with RBC indices. (a) There was negative correlation between HbA2/E peak values and RBC indices (Mean corpuscular volume (MCV) and Mean corpuscular hemoglobin) among all the three groups taken together. (b) There was positive correlation between HbA2/E and Red cell distribution width (RDW). (c) There was positive correlation between HbF values with MCV. The finding of positive correlation between HbA2/E and RDW may help in differentiating βthal (RDW normal) from HbE/βthal. In a patient with microcytic hypochromic blood picture and increased RDW, diagnosis of HbE/βthal should also be considered along with the more common Iron deficiency anemia. Thus, new insights into the knowledge of these diseases are important because they impart diagnostic challenges to all the experts involved in the treatment of anemic patients.

    A fatal case of primary amoebic encephalitis (PAM) in a 20 year old boy, a proven case of acute leukemic leukemia (ALL) type L2, in remission is described. No history of swimming could be elicited. The clinical presentation, the isolation of the amoeba from the cerebrospinal fluid (CSF), the poor response to amphotericin B, and the ultimately fatal outcome are all consistent with the diagnosis of PAM. On the basis of its ability to grow at temperature 42 degrees C and 45 degrees C, morphology of trophozoite, and the presence of flagellate forms in CSF, the amoeba was identified as Naegleria fowleri. Other drugs used in combination with amphotericin B are tetracycline, rifampicin, and miconazole. A possibility of PAM should always be considered in all cases of acute purulent meningoencephalitis in which no bacteria or fungus are found.

    Incidence of sickle cell trait in India is high in peninsular south, south-eastern, central and south-western India, while in north and north-eastern India, it is absent. Unicentric origin of SCD in the tribals of nilgiri hills in southern India has been proposed. The present study on the frequency of HbS trait and beta-globin gene haplotypes was conducted in the tribal-rich states of Chhattisgarh and Jharkhand to get an insight into the uneven distribution of HbS in India. Jharkhand borders with the HbS-high Odisha and Chhattisgarh, and HbS-low UP, Bihar and Bengal. Cellulose acetate gel electrophoresis was performed on the collected blood samples, to detect sickle haemoglobin (HbS) followed by DNA analysis. HbS associated beta-gene haplotype was constructed for the samples positive for HbS and all the tribals by PCR-RFLP. Out of 805 (Chhattisgarh - 261, Jharkhand - 544; greater than 36 percent tribals) samples analysed HbS frequency was 13 percent in Chhattisgarh and 3.3 percent in Jharkhand. Within Jharkhand, frequencies varied considerably from 10 percent in Tatanagar to nil in Sahibganj. The Arab-India (AI) haplotype of beta-globin cluster occurred in low frequency, confined mainly to Chhattisgarh. The most abundant haplotype in all the populations was the East Asian, + - - - - - +, rare in HbS, mainly in Sahibganj in east Jharkhand, which lacked AI. Our results indicate that besides the heterozygote advantage againstmalaria, the uneven regional distribution of HbS trait is because of restricted movement of two different populations, Dravidian from the south and Tibeto-Burman from the east into the Indianmainland which failed tomeet, we conjecture, due to severe climatic conditions (deserts and heat) prevailing through parts of central India. Apparently, Jharkhand became a zone of contact between them in recent times.

    Background & objectives: Childhood obesity is a known precursor to obesity and other non-communicable diseases (NCDs) in adulthood. However, the magnitude of the problem among children and adolescents in India is unclear due to paucity of well-conducted nationwide studies and lack of uniformity in the cut-points used to define childhood overweight and obesity. Hence an attempt was made to review the data on trends in childhood overweight and obesity reported from India during 1981 to 2013. Methods: Literature search was done in various scientific public domains from the last three decades using key words such as childhood and adolescent obesity, overweight, prevalence, trends, etc. Additional studies were also identified through cross-references and websites of official agencies. Results: Prevalence data from 52 studies conducted in 16 of the 28 States in India were included in analysis. The median value for the combined prevalence of childhood and adolescent obesity showed that it was higher in north, compared to south India. The pooled data after 2010 estimated a combined prevalence of 19.3 per cent of childhood overweight and obesity which was a significant increase from the earlier prevalence of 16.3 per cent reported in 2001-2005. Interpretation & conclusions: Our review shows that overweight and obesity rates in children and adolescents are increasing not just among the higher socio-economic groups but also in the lower income groups where underweight still remains a major concern.

    We use a neighborhood adaptive grid search procedure and reflectivity synthetics to model regional distance range (500-2000~km) seismograms recorded in India and to determine the variation in the crust and uppermost mantle structure across the subcontinent. The portions of the regional waveform which are most influenced by the crust and uppermost mantle structure are the 10-100~s period Pnl and fundamental mode surface waves. We use the adaptive grid search algorithm to match both portions of the seismogram simultaneously. This procedure results in a family of 1-D path average crust and upper mantle velocity and attenuation models whose propagation characteristics closely match those of the real Earth. Our data set currently consist of ˜20 seismograms whose propagation paths are primarily confined to the Ganges Basin in north India and the East Dharwar Craton of south India. The East Dharwar Craton has a simple and uniform structure consisting of a 36+/-2 km thick two layer crust, and an uppermost mantle with a sub-Moho velocity of 4.5~km/s. The structure of northern India is more complicated, with pronounced low velocities in the upper crustal layer due to the large sediment thicknesses in the Ganges basin.

    Fifteen epidemiological studies on psychiatric morbidity in India have been analysed. National all-India prevalence rates for ‘all mental disorders’ and five specific disorders have been worked out The national prevalence rates for ‘all mental disorders’ arrived at are 70.5 (rural), 73 (urban) and 73 (rural + urban) per 1000 population. Prevalence of schizophrenia is 2.5/1000 and this seems to be the only disorder whose prevalence is consistent across cultures and over time. Rates for depression, anxiety neurosis, hysteria and mental retardation are provided. Urban morbidity in India is 3.5 percent higher than the rural rate, but rural-urban differences are not consistent for different disease categories. In Hindi speaking north India, mental morbidity amongst factory workers is two and half times that of the non-industrial urban inhabitants and five times the rural morbidity. The present data are expected to serve as baseline rates for mental health planners and for psychiatrists interested in epidemiological studies. PMID:21407903

    Gondwana breakup since the Jurassic and the northward motion of India toward Eurasia were associated with formation of ocean basins and ophiolite obduction between and onto the Indian and Arabian margins. Here we reconcile marine geophysical data from preserved oceanic basins with the age and location of ophiolites in NW India and SE Arabia and seismic tomography of the mantle below the NW Indian Ocean. The North Somali and proto-Owen basins formed due to 160-133 Ma N-S extension between India and Somalia. Subsequent convergence destroyed part of this crust, simultaneous with the uplift of the Masirah ophiolites. Most of the preserved crust in the Owen Basin may have formed between 84 and 74 Ma, whereas the Mascarene and the Amirante basins accommodated motion between India and Madagascar/East Africa between 85 and circa 60 Ma and 75 and circa 66 Ma, respectively. Between circa 84 and 45 Ma, oblique Arabia-India convergence culminated in ophiolite obduction onto SE Arabia and NW India and formed the Carlsberg slab in the lower mantle below the NW Indian Ocean. The NNE-SSW oriented slab may explain the anomalous bathymetry in the NW Indian Ocean and may be considered a paleolongitudinal constraint for absolute plate motion. NW India-Asia collision occurred at circa 20 Ma deforming the Sulaiman ranges or at 30 Ma if the Hindu Kush slab north of the Afghan block reflects intra-Asian subduction. Our study highlights that the NW India ophiolites have no relationship with India-Asia motion or collision but result from relative India-Africa/Arabia motions instead.

  18. India's population--what is being done?

    Thus far, India's efforts to curtail population growth have consistently failed to meet official targets. The crude birthrate (per 1000 population per year) is highest in the belt of 6 Hindi-speaking states, which include Rajasthan (40), Madhya Pradesh (38.5), Uttar Pradesh (38.4), Bihar (37.2), and Haryana (35.9). The rates are slightly lower in the other large North Indian States. The rate is 33.6 for India as a whole according to 1983 data. 3 of the South Indian states have the lowest crude birthrates: Kamataka (28.7), Tamil Nadu (27.8), and Kerata (24.9). Each of India's successive Five Year Plans gave increasingly more emphasis to population control, but the key tactical features have stayed the same. Population control comes under the Ministry of Health and Family Welfare, with family planning services provided through the free health delivery system. The main strategy continues to be to persuade people on an individual basis to accept the small family norm by a wide range of advertising and educational efforts. As of 1986, the family planning establishment had grown to gigantic proportions, employing half a million people in the family planning and health services. The Five Year Plan initiated in July 1985 continues the same approach but with added features. "Green cards" are given to those who accept sterilization after 2 children, allowing them a wide range of benefits such as low interest housing loans, preference in getting housing plots and enterprise loans, and salary increases for government employees. Health workers and other government employees have quotas of persons to motivate for contraceptive acceptance. They receive a small monetary incentive, which they often give to the acceptors so they can maintain their quotas and keep their jobs. The 1986 Revised Strategy for Family Planning is essentially more of the same with family planning more integrated with the health delivery system. Foreign and international donor agencies frequently have placed

  19. Astronomical Instruments in India

    Sarma, Sreeramula Rajeswara

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    Troodontid dinosaurs share a close ancestry with birds and were distributed widely across Laurasia during the Cretaceous. Hundreds of occurrences of troodontid bones, and their highly distinctive teeth, are known from North America, Europe and Asia. Thus far, however, they remain unknown from Gondwanan landmasses. Here we report the discovery of a troodontid tooth from the uppermost Cretaceous Kallamedu Formation in the Cauvery Basin of South India. This is the first Gondwanan record for troodontids, extending their geographic range by nearly 10,000 km, and representing the first confirmed non-avian tetanuran dinosaur from the Indian subcontinent. This small-bodied maniraptoran dinosaur is an unexpected and distinctly 'Laurasian' component of an otherwise typical 'Gondwanan' tetrapod assemblage, including notosuchian crocodiles, abelisauroid dinosaurs and gondwanathere mammals. This discovery raises the question of whether troodontids dispersed to India from Laurasia in the Late Cretaceous, or whether a broader Gondwanan distribution of troodontids remains to be discovered.

    Widespread infection of highly pathogenic avian influenza A H5N1 was reported from backyard and commercial poultry in West Bengal (WB), an eastern state of India in early 2008. Infection gradually spread to Tripura, Assam and Sikkim, the northeastern states, with 70 outbreaks reported between January 2008 and May 2009. Whole genome sequence analysis of three isolates from WB, one isolate from Tripura along with the analysis of hemagglutinin (HA) and neuraminidase (NA) genes of 17 other isolates was performed during this study. In the HA gene phylogenetic tree, all the 2008-09 Indian isolates belonged to EMA3 sublineage of clade 2.2. The closest phylogenetic relationship was found to be with the 2007-09 isolates from Bangladesh and not with the earlier 2006 and 2007 Indian isolates implying a third introduction into the country. The receptor-binding pocket of HA1 of two isolates from WB showed S221P mutation, one of the markers predicted to be associated with human receptor specificity. Two substitutions E119A (2 isolates of WB) and N294S (2 other isolates of WB) known to confer resistance to NA inhibitors were observed in the active site of neuraminidase. Several additional mutations were observed within the 2008-09 Indian isolates indicating genetic diversification. Overall, the study is indicative of a possible endemicity in the eastern and northeastern parts of the country, demanding active surveillance specifically in view of the critical mutations that have been observed in the influenza A H5N1 viruses.

A very simple method for converting cow dung into a flammable gase, biogas, has been used to improve the lives of over 10 million rural inhabitants of India. The dung provides cooking fuel, electric power, and as a by product an even better fertilizer than manure. Topics covered include the following: why biogas works in India; the economics of self-sufficiency in rural India; finding a strategy that works; tapping into the potential in the rural areas.

  3. Tracking Arabia-India motion from Miocene to Present

    Although small, the present-day Arabia-India motion has been captured by several global and regional geodetic surveys that consistently show dextral motion of a few mm/yr, either transpressive or transtensive (Fournier et al., 2008). This motion is accommodated along the Owen Fracture Zone, an active strike-slip boundary that runs for more than 700 km from the Somalia-India-Arabia triple junction in the south to the Dalrymple trough in the north. Two recent marine cruises conducted along this fault aboard the BHO Beautemps-Beaupré (AOC 2006 and OWEN 2009) using a high resolution multibeam sounder (Simrad EM120, 10 m vertical resolution) provided a complete map of the active fault and confirmed a present-day pure dextral motion. The surface breaks closely follow a small circle of the Arabia-India motion, with several pull-part basins at the junctions between the main segments of the fault. Geomorphologic offsets reach 10 km, suggesting that the mapped fault has been active with the same style for past several million years. When did this motion start? The difficulty in tracking the past Arabia-India motion is that there is no direct kinematic indicator available, since the boundary has been strike-slip and/or convergent during the Tertiary. Motion was most probably sinistral during the rapid northward travelling of India towards Eurasia in the early Tertiary, Arabia being rigidly attached to Africa until the opening of the Gulf of Aden. However, the nature and location of the Arabia-India boundary at that time remain speculative. Throughout the Miocene, the relative motion between India and Arabia has been indirectly recorded at the Sheba and Carslberg ridges, the former recording Arabia-Somalia motion (opening of the Gulf of Aden) and the latter India-Somalia motion (Indian Ocean opening). Both ridges have been studied with some details recently, using up to date magnetic lineations identification (Merkouriev and DeMets, 2006; Fournier et al., 2009). We combine

    In many developed countries, notification of cancer cases is compulsory. Developing countries including India accounts for more than half of new cancer cases in the world, however notification of cancer is not yet mandatory. The primary purpose of notification is to effect prevention and control and better utilization of resources. It is also a valuable source for incidence, prevalence, mortality and morbidity of the disease. Notification of cancer will lead to improved awareness of common etiologic agents, better understanding of common preventable causes and better utilization of health resources with better monitoring and evaluation of the effectiveness of health programs such as cancer screening and cancer treatment programs, which ultimately might improve survival. Notification of cancer can be done by the doctor or the hospital. Akin to the integrated disease surveillance project where more than 90% of the districts report weekly data through E-mail/portal, notification of cancer can be implemented if it is incorporated into the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke scheme. The need of the hour is cancer notification in India.

Despite the strong link between climate and society, our knowledge of the long-term monsoon variability is incomplete over the Indian subcontinent. Here we reconstruct the Holocene paleoclimate in the core monsoon zone (CMZ) of the Indian peninsula using a sediment core recovered offshore from the mouth of Godavari River. Carbon isotopes of sedimentary leaf waxes provide an integrated and regionally extensive record of the flora in the CMZ and document a gradual increase in aridity-adapted vegetation from ˜4,000 until 1,700 years ago followed by the persistence of aridity-adapted plants after that. The oxygen isotopic composition of planktonic foraminifer Globigerinoides ruber detects unprecedented high salinity events in the Bay of Bengal over the last 3,000 years, and especially after 1,700 years ago, which suggest that the CMZ aridification intensified in the late Holocene through a series of sub-millennial dry episodes. Cultural changes occurred across the Indian subcontinent as the climate became more arid after ˜4,000 years. Sedentary agriculture took hold in the drying central and south India, while the urban Harappan civilization collapsed in the already arid Indus basin. The establishment of a more variable hydroclimate over the last ca. 1,700 years may have led to the rapid proliferation of water-conservation technology in south India.

  7. Protein intakes in India.

    Indian diets derive almost 60 % of their protein from cereals with relatively low digestibility and quality. There have been several surveys of diets and protein intakes in India by the National Nutrition Monitoring Board (NNMB) over the last 25 years, in urban and rural, as well as in slum dwellers and tribal populations. Data of disadvantaged populations from slums, tribals and sedentary rural Indian populations show that the protein intake (mainly from cereals) is about 1 gm/kg/day. However, the protein intake looks less promising in terms of the protein digestibility corrected amino acid score (PDCAAS), using lysine as the first limiting amino acid, where all populations, particularly rural and tribal, appear to have an inadequate quality to their protein intake. The protein: energy (PE) ratio is a measure of dietary quality, and has been used in the 2007 WHO/FAO/UNU report to define reference requirement values with which the adequacy of diets can be evaluated in terms of a protein quality corrected PE ratio. It is likely that about one third of this sedentary rural population is at risk of not meeting their requirements. These levels of risk of deficiency are in a population with relatively low BMI populations, whose diets are also inadequate in fruits and vegetables. Therefore, while the burden of enhancing the quality of protein intake in rural India exists, the quality of the diet, in general, represents a challenge that must be met.

Joint venture agreements were finalized for 19 blocks over 94,000 km/sup 2/ in the Algerian venture. Although official information is scarce for Algeria and Libya, seismic activity probably increased in 1980 compared to 1979. Exploration drilling activity increased with 121 wildcats drilled compared to 93 during the previous year. This effort led to 40 discoveries, a 34.5% success ratio. Chevron was especially successful in wildcatting, with 6 oil discoveries for 8 wells drilled in the interior basins of Sudan. One Moroccan discovery can be considered as a highlight: the BRPM Meskala 101 well in the Essaouira basin found an apparently large amount of gas in Triassic sandstones. This discovery deserves special attention, since the gas has been found in Triassic pays rather than in the usual Jurassic pays in the Essaouira basin. Oil production in North Africa decreased from about 13.5% in 1980, with about 3,405,000 barrels of oil per day compared to 3,939,500 barrels of oil per day in 1979. When oil output strongly decreased in Algeria (-16.4%) and Libya (-15.6%), Tunisian production peaked at 116,287 barrels of oil per day and Egypt production also peaked at 584,148 barrels of oil per day. Total gas production in 1980 strongly declined from 44%, mostly due to the decline of the Algerian gas production. 8 figures, 40 tables.

    Surgical practice in India is mostly managed by the central and state governments and is totally government financed, offering free medical aid. However, with the economic growth and affluence of the middle-class population in urban areas, more and more hospitals, nursing homes, and clinics managed by the private sector are arising in cities and towns. Privately owned hospitals are built and managed by large industrial houses and trusts. It is essential, according to government directives, for these hospitals to have certain numbers of general beds that will provide for the economically weaker sections of the population. Medical insurance is popular amongst the urban population; in addition to well-established insurance companies, many new medical service reimbursement organizations are forming. Surgical care standards are uniformly high in the larger teaching institutions and hospitals run by the private sector in major cities in India, in which superspecialty surgical care that meets worldwide standards is available in addition to general surgical care. These hospitals are manned by surgeons holding master's degrees in general surgery, superspecialties, and subspecialties. In the hospitals and dispensaries in rural areas, only basic surgical facilities are available; for major surgical procedures, the patients are referred to the closest urban hospitals. Therefore, the government of India is placing more and more emphasis on building hospitals that offer better surgical facilities away from the cities and towns. A diploma course in surgery is run by the National Board of Surgery, and these diplomates are encouraged to practice more in rural areas and small hospitals. Economic constraints and the population explosion are the biggest hurdles to progress in surgical care, teaching, and research activities. With the advancement in education and growth of the economy, more and more multinationals are walking into the field of medical care, which is proving to be a

These early sauropod genera are related, but their phylogenetic positions remain unresolved. Sauropods originated in Laurasia (Thailand and vicinity) or Pangea (broadly, Thailand, China, India), with at least three additional steps involving expansion and diversification through the Middle Jurassic.

    This paper takes a close look at India's literacy rate by exploring whether the officially "literate" can read and at what level. In a large sample, aged 7+, drawn from four Hindi-speaking states, two methods were used to measure literacy. One was the standard Census Method (CM) which relies on self-reporting and the other was a Reading Method (RM) which required the same individuals to actually read a simple text at grade 2 level. The findings revealed a substantial difference between the reading literacy rates obtained by CM and RM. CM over-reported RM by 16%. The overestimation was higher for males. Decoding skills were found to erode in most cases after completion of primary schooling, assuming no further education. A minimum grade 8-9 education was required for decoding skills to not deteriorate after schooling.

    The golden jackal (Canis aureus) is one of the most common and widely distributed carnivores in India but phylogeographic studies on the species have been limited across its range. Recent studies have observed absence of mitochondrial (mt) DNA diversity in European populations while some North African populations of golden jackal were found to carry gray wolf (Canis lupus lupaster) mtDNA lineages. In the present study, we sequenced 440 basepairs (bp) of control region (CR) and 412 bp of cytochrome b (cyt b) gene of mtDNA from 62 golden jackals sampled from India (n = 55), Israel (n = 2) and Bulgaria (n = 5), to obtain a total of eighteen haplotypes, comprising sixteen from India and one each from Israel and Bulgaria. Except for three previously described haplotypes represented by one cyt b and one CR haplotype both from India, and one CR haplotype from Bulgaria, all haplotypes identified in this study are new. Genetic diversity was high in golden jackals compared to that reported for other canids in India. Unlike the paraphyletic status of African conspecifics with the gray wolf, the Indian (and other Eurasian) golden jackal clustered in a distinct but shallow monophyletic clade, displaying no evidence of admixture with sympatric and related gray wolf and domestic dog clades in the region. Phylogeographic analyses indicated no clear pattern of genetic structuring of the golden jackal haplotypes and the median joining network revealed a star-shaped polytomy indicative of recent expansion of the species from India. Indian haplotypes were observed to be interior and thus ancestral compared to haplotypes from Europe and Israel, which were peripheral and hence more derived. Molecular tests for demographic expansion confirmed a recent event of expansion of golden jackals in the Indian subcontinent, which can be traced back ~ 37,000 years ago during the late Pleistocene. Our results suggest that golden jackals have had a potentially longer evolutionary history in India

  1. Reproductive health in India.

    PubMed

    1994-08-01

    In India, prenatal tests are used to determine the sex of the fetus and, if it is female, it is often aborted. In response to sex discrimination in utero, the Forum against Sex Determination and Sex Preselection was formed in 1985. It began a campaign against using prenatal tests to determine sex for the subsequent abortion of female fetuses. The 1989 Maharashtra Regulation of Prenatal Diagnostic Techniques was a direct result of this campaign. The forum expanded to examine other reproductive technologies, particularly long-lasting contraceptives that cause systemic changes in women's bodies, and it has become more concerned about women's rights in general. It has renamed itself the Forum for Women's Health. The state translates the need for contraceptives into population control. It provides health care through primary health centers and subcenters. The maternal and child health program provides health care only to 15-45 year old women. The government knows that abortion and childbirth are major contributors to maternal mortality, so it provides safe abortion through its centers. Yet, prevailing conditions and social values keep women from using these services, so they resort to unhygienic abortions. The government considers repeated childbearing as the only cause of maternal mortality and ignores that poverty, malnutrition, and social position can also be responsible for maternal deaths. This attitude justifies its coercion of women to use contraception. India's government is presently pushing provider-controlled, long-acting methods. It supports high tech research of antifertility vaccines. Female barrier methods are not marketed. The family planning program is based on targets and incentives/ disincentives. The government has recently set up sterilization camps in Bombay. The forum is concerned that providers will not fully inform women about side effects of the injectables and about other possible contraceptive methods. Women are being trained in self-help and

    As a result of NSG restrictions, India cannot import the natural uranium required to fuel its Pressurized Heavy Water Reactors (PHWRs); consequently, it is forced to rely on the expediency of domestic uranium production. However, domestic production from mines and byproduct sources has not kept pace with demand from commercial reactors. This shortage has been officially confirmed by the Indian Planning Commission’s Mid-Term Appraisal of the country’s current Five Year Plan. The report stresses that as a result of the uranium shortage, Indian PHWR load factors have been continually decreasing. The Uranium Corporation of India Ltd (UCIL) operates a number of underground mines in the Singhbhum Shear Zone of Jharkhand, and it is all processed at a single mill in Jaduguda. UCIL is attempting to aggrandize operations by establishing new mines and mills in other states, but the requisite permit-gathering and development time will defer production until at least 2009. A significant portion of India’s uranium comes from byproduct sources, but a number of these are derived from accumulated stores that are nearing exhaustion. A current maximum estimate of indigenous uranium production is 430t/yr (230t from mines and 200t from byproduct sources); whereas, the current uranium requirement for Indian PHWRs is 455t/yr (depending on plant capacity factor). This deficit is exacerbated by the additional requirements of the Indian weapons program. Present power generation capacity of Indian nuclear plants is 4350 MWe. The power generation target set by the Indian Department of Atomic Energy (DAE) is 20,000 MWe by the year 2020. It is expected that around half of this total will be provided by PHWRs using indigenously supplied uranium with the bulk of the remainder provided by breeder reactors or pressurized water reactors using imported low-enriched uranium.

    This article suggests how the waging of war in an imperial setting may have reshaped military and civilian relations in India from 1939-45. The number of troops stationed in India had repercussions for society and local politics. The article investigates widespread prostitution as one aspect of the gendered wartime economy. Indian prostitution was closely linked to militarization and to the effects of the 1943 Bengal famine. The article also argues this was symptomatic of a more far-reaching renegotiation of the interactions between men and women in the Indian Empire of the 1940s. Other Indian, European, North American and Anglo-Indian women worked as nurses, with the Red Cross and in a variety of roles towards the war effort. Women were subject to new social and sexual demands due to the increased numbers of troops stationed in India in the 1940s.

    PubMed

    2015-01-01

    Available without prescriptions in India since 2005, emergency contraceptive pills (ECPs) and their advertisements have provided women with increased contraceptive options and a vocabulary to talk about their reproductive lives. I draw on long-term fieldwork with women in urban India about ECPs, demonstrating a new form of 'stratified contraception' enabled by these pills and their advertisements. I posit that there are within India spaces that replicate the luxuries and privileges of the global North. These material conditions, I suggest, are replicated when it comes to contraception as there are hubs of women consumers of contraception and contraceptive advertising that participate in an 'imagined cosmopolitanism' within the global South in close proximity to 'contraceptive ghettos.' Moving beyond simplistic binaries, I outline three major stratifications along which women experience this medical technology and outline the implications for women and their contraceptive choices when notions of northern privilege exist in the 'South.'

  8. Coal ash utilization in India

    1998-12-31

    This paper describes methods of coal combustion product (CCP) management successfully employed in the US and considers their potential application in India. India produces about 66 million tons per year (mty) of coal ash from the combustion of 220 mty of domestically produced coal, the average ash content being about 30--40 percent as opposed to an average ash content of less than 10 percent in the US In other words, India produces coal ash at about triple the rate of the US. Currently, 95 percent of this ash is sluiced into slurry ponds, many located near urban centers and consuming vast areas of premium land. Indian coal-fired generating capacity is expected to triple in the next ten years, which will dramatically increase ash production. Advanced coal cleaning technology may help reduce this amount, but not significantly. Currently India utilizes two percent of the CCP`s produced with the remainder being disposed of primarily in large impoundments. The US utilizes about 25 percent of its coal ash with the remainder primarily being disposed of in nearly equal amounts between dry landfills and impoundments. There is an urgent need for India to improve its ash management practice and to develop efficient and environmentally sound disposal procedures as well as high volume ash uses in ash haulback to the coalfields. In addition, utilization should include: reclamation, structural fill, flowable backfill and road base.

    The caprellid fauna of India is investigated. A total of 538 samples (including algae, seagrasses, sponges, hydroids, ascidians, bryozoans, encrusted dead corals, coral rubble, fine and coarse sediments) were collected from 39 stations along the coast of India, covering a wide diversity of habitats from intertidal to 12 m water depth. A new species ( Jigurru longimanus n.sp.) is described, and figures of the 11 valid species reported so far from India are given together with a key for their identification. No caprellids were found in sediments from the northeast (16-20ºN) coast of India while they were abundant in the southeast and west coast. Decreases in salinity due to river discharges associated with lower values of oxygen, higher water temperatures and lower nutrient inputs along the east coast could explain these differences in caprellid composition between the two coastlines. Significantly, lower abundance of caprellids in India, as in other tropical ecosystems, is probably related to the lack of species belonging to the genus Caprella, which reach very high abundances in temperate waters.

    Demography, migration, economy, employment, education, planning, housing and transportation in the Delhi Union Territory are described. The Territory is an administrative district that includes Old Delhi, the site of the ancient walled city, the New Delhi Municipal Corporation, the center of government, the Delhi Cantonment, a military center, and 27 smaller towns, many of which are rural in character. The Delhi Territory is notable for its relatively high per capita income ($321), high sex ratio (124), high proportion of recent migrants (over half), but also high employment rate and educational status of these migrants. Much of the economy is based on government service, retail trade and services. School enrollment is high, nearly 100% of primary school age children, 77% of middle school, and 50% of secondary school. Rapid growth has stressed the public health, sanitation, housing, electric power systems. Transportation is coping relatively well, considering that 20% of all motor vehicles in India are in Delhi. 50% of daily trips are made by bus, 22% by bicycle, 10% by motorcycles, and 4% by cars. Accommodations for tourists in Delhi's old center are good in both expensive and inexpensive hotels.

    Expanded newborn screening (NBS) is aimed for early detection and intervention of treatable inborn errors of metabolism and also to establish incidence of these disorders in this part of the globe. The first expanded NBS programme initiated in the capital city of Andhra Pradesh to screen all the newborns born in four major Government Maternity Hospitals in Hyderabad by heel prick capillary blood collected on S&S 903 filter paper. Chromatographic (TLC and HPLC), electrophoretic (cellulose acetate and agarose) and ELISA based assays have been employed for screening of common inborn errors of metabolism. This study has shown a high prevalence of treatable Inborn errors of metabolism. Congenital hypothyroidsm is the most common disorder (1 in 1700) followed by congenital Adrenal Hyperplasia (1 in 2575) and Hyperhomocystenemia (1 in 100). Interestingly, a very high prevalence of inborn errors of metabolism to the extent of 1 in every thousand newborns was observed. The study reveals the importance of screening in India, necessitating nation wide large-scale screening.

  12. Decriminalising homosexuality in India.

    2009-11-01

    This paper examines the successful fight against the provision in Section 377 of the Penal Code of India that criminalised private consensual sex between adults of the same sex. This law had led to serious discrimination against people engaging in homosexual acts, who were subjected to frequent beatings and blackmail attempts by police, who used the threat of prosecution against them. NGOs working with sexual minorities have also been harassed and sometimes charged under Section 377. By stigmatising homosexuality and threatening gay men with prison, the law is also likely to have impeded the battle against HIV. The provision was read down in July 2009 after an innovative, sustained, mass media campaign by activists. The Voices Against 377 coalition brought together sexuality and lesbian, gay, bisexual and transgender (LGBT) organisations, who were previously marginalised, with groups working in areas such as children's rights and feminist groups, showing that support for non-discrimination towards sexual minorities was broad-based. Further legal and social changes are needed for LGBT individuals to gain full acceptance and equality within Indian society. However, the judgement transcended the LGBT issue with the implication of protection for all minorities and introduced for the first time in South Asia the idea of sexual citizenship.

    2014-01-01

    India is one of the 12 mega biodiversity countries of the world, which represents 11% of world's flora in about 2.4% of global land mass. Approximately 28% of the total Indian flora and 33% of angiosperms occurring in India are endemic. Higher human population density in biodiversity hotspots in India puts undue pressure on these sensitive eco-regions. In the present study, we predict the future distribution of 637 endemic plant species from three biodiversity hotspots in India; Himalaya, Western Ghats, Indo-Burma, based on A1B scenario for year 2050 and 2080. We develop individual variable based models as well as mixed models in MaxEnt by combining ten least co-related bioclimatic variables, two disturbance variables and one physiography variable as predictor variables. The projected changes suggest that the endemic flora will be adversely impacted, even under such a moderate climate scenario. The future distribution is predicted to shift in northern and north-eastern direction in Himalaya and Indo-Burma, while in southern and south-western direction in Western Ghats, due to cooler climatic conditions in these regions. In the future distribution of endemic plants, we observe a significant shift and reduction in the distribution range compared to the present distribution. The model predicts a 23.99% range reduction and a 7.70% range expansion in future distribution by 2050, while a 41.34% range reduction and a 24.10% range expansion by 2080. Integration of disturbance and physiography variables along with bioclimatic variables in the models improved the prediction accuracy. Mixed models provide most accurate results for most of the combinations of climatic and non-climatic variables as compared to individual variable based models. We conclude that a) regions with cooler climates and higher moisture availability could serve as refugia for endemic plants in future climatic conditions; b) mixed models provide more accurate results, compared to single variable based

    Mucormycosis remains a devastating invasive fungal infection, with high mortality rates even after active management. The disease is being reported at an alarming frequency over the past decades from India. Indian mucormycosis has certain unique features. Rhino-orbito-cerebral presentation associated with uncontrolled diabetes is the predominant characteristic. Isolated renal mucormycosis has emerged as a new clinical entity. Apophysomyces elegans and Rhizopus homothallicus are emerging species in this region and uncommon agents such as Mucor irregularis and Thamnostylum lucknowense are also being reported. This review focuses on these distinct features of mucormycosis observed in India.

    Jogini is the name for a female sexually exploited temple attendant and is used interchangeably with Devadasi in the state of Andhra Pradesh, India. Jogini are twice more likely than other women who are used for sexual intercourse in India to be HIV positive, and their rate of mortality from HIV is 10 times the total mortality rate for all women in India. The four states in India with the most Jogini also have the highest prevalence of HIV. The following case is unfortunately typical of the Jogini and sheds light on a potentially disastrous public health problem in rural South India. PMID:25015167

    This article discusses the nature, magnitude, causes, and consequences of female child prostitution in India and offers measures for control and prevention of girl prostitution. Data are obtained from the 6-city study of prostitution and the author's own research. An estimated 85% of all prostitutes in Calcutta and Delhi entered the work at an early age. The numbers are rising. The promotion of tourism is linked with prostitution. Girl prostitutes are primarily located in low-middle income areas and business districts and are known by officials. Brothel keepers regularly recruit young girls. An estimated 33% of prostitutes are young girls. In Bangalore, Calcutta, Delhi, and Hyderabad, there are an estimated 10,000 girl prostitutes. UNICEF estimates about 300,000 child prostitutes. Girl prostitutes are grouped as common prostitutes, singers and dancers, call girls, religious prostitutes or devdasi, and caged brothel prostitutes. Religious prostitutes are mainly found in the South. Caged ones are found in Bombay. A little over 50% of prostitutes come from other countries, such as Nepal and Bangladesh. The girls tend to come from urban slums and poor rural areas. High prostitute supply regions include Andhra Pradesh, Karnataka, Maharashtra, Uttar Pradesh, Tamil Nadu, and West Bengel states. About 85% are Hindus, and about 66% are from scheduled castes and tribes. Bangalore and Bombay have a higher proportion of girl prostitutes. The causes of prostitution include ill treatment by parents, bad company, family prostitutes, social customs, inability to arrange marriage, lack of sex education, media, prior incest and rape, early marriage and desertion, lack of recreational facilities, ignorance, and acceptance of prostitution. Economic causes include poverty and economic distress. Psychological causes include desire for physical pleasure, greed, and dejection. Most enter involuntarily. A brief profile is given of the life of a prostitute.

    2014-01-01

    Cholera is a global health problem as several thousands of cases and deaths occur each year. The unique epidemiologic attribute of the disease is its propensity to occur as outbreaks that may flare-up into epidemics, if not controlled. The causative bacterial pathogen Vibrio cholerae prevails in the environment and infects humans whenever there is a breakdown in the public health component. The Indian subcontinent is vulnerable to this disease due its vast coastlines with areas of poor sanitation, unsafe drinking water, and overcrowding. Recently, it was shown that climatic conditions also play a major role in the persistence and spread of cholera. Constant change in the biotypes and serotypes of V. cholerae are also important aspects that changes virulence and survival of the pathogen. Such continuous changes increase the infection ability of the pathogen affecting the susceptible population including the children. The short-term carrier status of V. cholerae has been studied well at community level and this facet significantly contributes to the recurrence of cholera. Several molecular tools recognized altering clonality of V. cholerae in relation with the advent of a serogroup or serotype. Rapid identification systems were formulated for the timely detection of the pathogen so as to identify and control the outbreak and institute proper treatment of the patients. The antimicrobials used in the past are no longer useful in the treatment of cholera as V. cholerae has acquired several mechanisms for multiple antimicrobial resistance. This upsurge in antimicrobial resistance directly influences the management of the disease. This chapter provides an overview of cholera prevalence in India, possible sources of infection, and molecular epidemiology along with antimicrobial resistance of V. cholerae.

  3. Aerosol properties over south india during different seasons

    Sivaprasad, P.; Babu, C. A.; Jayakrishnan, P. R.

    Aerosols play an important role in the radiation balance and cloud properties, thereby affect the entire climatology of the earth-atmosphere system. Besides natural sources like dust, seasalt and natural sulphates, anthropogenic activities also inject aerosols like soot and industrial sulphates. Of these sea-salt and sulphates scatter the solar radiation. Soot is an absorbing aerosol while soil dust and organic matters are partly absorbing aerosols. Wind and rainfall are major factors affecting the transportation and deposition of the aerosols. India is a country blessed with plenty of monsoon rains. Winter (December to February), summer (March to May), monsoon (June to September) and post monsoon (October to November) are the four seasons over the region. Aerosol properties vary according to the season. Natural aerosols blown from the deserts have a major role in the aerosol optical depth over India. Of this, dust from Arabian desert that is carried by the winds are most important. The aerosol optical depth of south India is entirely different from that of north India. Maximum aerosol concentration is found over Gangetic plane in most of the seasons, whereas entire south India shows less aerosol optical depth. In the present study the aerosol properties of south India is analysed in general. Particular analysis is carried out for the four regions in the east and west coasts around Chennai, Kolkotha, Mumbai and Cochin. Chennai and Kolkotha are situated in the east coast whereas Cochin and Mumbai are in the west coast. These are industrial cities in India. Chennai region does not get monsoon rainfall since it is situated in the leeward side of Western ghats. But in the post monsoon season Chennai gets good amount of rainfall. Other three regions get good amount of rainfall during monsoon season. The study uses Terra MODIS, TOMS, NCEP/NCAR and TRMM data. Aerosol properties are analysed using Terra MODIS and Nimbus TOMS data. The variations of the aerosol optical

    South India is one of the oldest geophysical regions mainly occupied by Dravidian language-speaking people. Here a random panel of 61 unrelated Nadar healthy individual from Tamil Nadu State were analyzed and compared with other populations of India and the world. HLA-A, B and C alleles frequencies and their haplotype frequencies were determined by high-resolution typing of genomic DNA. The analysis revealed that the Nadar caste of South India have several characters shared with East Asian populations consistent with the demographic history of South India, as well as specific features including several unique alleles such as A*03011, A*31011, B*15011, B*3501, B*51011, Cw*02022. In addition, haplotypes such as A*31011-Cw*02022-B*3501, A*03011-Cw*04011-B*4406 and A*2402101-Cw*04011-B*51011 are of high frequency in both these populations but are rare or absent in other populations of India and the world. The study suggests that a comparatively lesser degree of genetic admixture occurred between the South Indian and North Indian racial groups than that between South Indian and East Asian groups.

    For the past two weeks floods have ravaged Bangladesh (center) and eastern India (draped around Bangladesh to the north), killing over 50 people and displacing hundreds of thousands from their homes. These false-color images acquired on July 15 and 16, 2002, by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite show some of the worst flooding. The dark brown, swollen river in the images (top right on July 16; center on July 15) is the Brahmaputra River, which flows through the middle of the Indian state of Assam at the foothills of the Himalaya Mountains. A large, black area south of the Brahmaputra (partially obscured by clouds) shows flooded areas in Bangladesh. Floods of this magnitude have been known to occur in southern Bangladesh and are caused by storms washing seawater over coastal regions. This year, however, unrelenting torrential rains across the entire eastern sub-continent gave rise to the deluge. The massive amounts of rainwater that fell on Nepal and Assam drained into an already waterlogged eastern Bangladesh. Normally, the Brahmaputra River and its tributaries would resemble a tangle of thin lines, and the large black patches in Bangladesh would be the color of the rest of the land surface, tan. In these false-color images, land is tan, and clouds are pink and white. Water comes across as black or dark brown, depending on its sediment level, with clearer water being closer to black.

    1984-09-01

    The east coast of India is considered to be a divergent margin formed during the fragmentation of Gondwanaland during the late Mesozoic. The four sedimentary basins located along this coast-cauvery, Palar, Krishna-Godavari, and Mahanadi (from south to north)- have their seaward extensions into the Bay of Bengal where some of them have built a 5-6 km (16,000-20,000 ft) thick late Mesozoic to Holocene sedimentary section. The basins have two or more cycles of deposition. During the first (rift) cycle in the Early Cretaceous (stage 1), nonmarine to paralic sandstones and shales were deposited in the interior grabens. The second cycle (coastal margin), during the Tertiary, which is well developed in all basins except Palar, was superimposed unconformably on the horst-graben morphology of the Cretaceous basins. Although no commercial discoveries have been identified to date, significant oil and/or gas shows have been encountered in some of the tests, with definite but lesser shows in others. All important shows observed to date are located on horsts and other structural highs, but stratigraphic controls are very likely to be associated with sub-Upper cretaceous unconformities, between Cretaceous and Paleocene and between Miocene and Pliocene. Oil and gas plays in each sequence appear to be limited by the fault block in which the particular sequence is most completely developed and each appears to contain indigenous source rock providing hydrocarbons to the reservoirs in the sequence.

    1991-03-01

    The crisis in the Persian Gulf has reawakened concerns over the spread of nuclear arms. Even before its invasion of Kuwait, Iraq's history of aggression and support for international terrorism triggered fears in Washington that its acquisition of nuclear weapons might damage international stability and US interests far more than the emergence of India, Israel, Pakistan, and South Africa as de facto nuclear powers. Thus, when the Gulf War began on January 16, Iraq's nuclear sites were among the first attacked by allied air strikes. Unfortunately, Iraq has not been the only hostile proliferator looming on the horizon. North Korea, which has been no less dedicated than Iraq to the use of violence to advance its expansionist goals, has also tenaciously pursued a nuclear-weapons capability. Moreover, the North Korean program is considerably closer to bearing fruit than the Iraqi effort. And although North Korea, like Iraq, has signed the Nuclear Nonproliferation Treaty, unlike Iraq it has refused to conclude the safeguards agreement with the International Atomic Energy Agency that the treaty requires.

  2. India-Eurasia collision triggers formation of an oceanic microplate

    2016-04-01

    Detailed mapping of seafloor tectonic fabric in the Indian Ocean, using high-resolution satellite-derived vertical gravity gradient data, reveals an extinct Pacific-style oceanic microplate - the Mammerickx Microplate - west of the Ninetyeast Ridge. It is one of the first Pacific-style microplates to be mapped outside the Pacific basin, suggesting that geophysical conditions during formation probably resembled those that have dominated at eastern Pacific ridges. The microplate formed at the Indian-Antarctic ridge and is bordered by an extinct ridge in the north and pseudofault in the south, whose conjugate is located north of the Kerguelen Plateau. Independent microplate rotation is indicated by asymmetric pseudofaults and rotated abyssal hill fabric, also identified in multibeam data. Magnetic anomaly picks and age estimates calculated from published spreading rates suggest formation during chron 21o (~47.3 Ma). Plate reorganizations can trigger ridge propagation and microplate development, and we propose that formation of the Mammerickx Microplate is linked with the initial 'soft' stage of the India-Eurasia collision. The collision altered the stress regime at the Indian-Antarctic ridge, leading to a change in segmentation and ridge propagation from an establishing transform fault. Fast Indian-Antarctic spreading that preceded microplate formation, and Kerguelen Plume activity may have facilitated ridge propagation via the production of thin and weak lithosphere. However, both factors had been present for tens of millions of years and are therefore unlikely to have triggered the event. Prior to the collision, this combination of fast spreading and plume activity was responsible for the production of a wide region of undulate seafloor to the north of the extinct ridge and 'W' shaped lineations that record back and forth ridge propagation. Microplate formation provides a means of dating the onset of the India-Eurasia collision, and is completely independent of and

    Bluetongue (BT) is an insectborne endemic disease in India. Although infections are observed in domestic and wild ruminants, the clinical disease and mortality are observed only in sheep, especially in the southern states of the country. The difference in disease patterns in different parts of the country could be due to varied climatic conditions, sheep population density and susceptibility of the sheep breeds to BT. Over the five decades after the first report of BT in 1964, most of the known serotypes of bluetongue virus (BTV) have been reported from India either by virus isolation or by detection of serotype-specific antibodies. There have been no structured longitudinal studies to identify the circulating serotypes throughout the country. At least ten serotypes were isolated between 1967 and 2000 (BTV-1-4, 6, 9, 16-18, 23). Since 2001, the All-India Network Programme on Bluetongue and other laboratories have isolated eight different serotypes (BTV-1-3, 9, 10, 12, 16, 21). Genetic analysis of these viruses has revealed that some of them vary substantially from reference viruses, and some show high sequence identity with modified live virus vaccines used in different parts of the world. These observations have highlighted the need to develop diagnostic capabilities, especially as BT outbreaks are still declared based on clinical signs. Although virus isolation and serotyping are the gold standards, rapid methods based on the detection of viral nucleic acid may be more suitable for India. The epidemiological investigations also have implications for vaccine design. Although only a handful serotypes may be involved in causing outbreaks every year, the combination of serotypes may change from year to year. For effective control of BT in India, it may be pertinent to introduce sentinel and vector traps systems for identification of the circulating serotypes and to evaluate herd immunity against different serotypes, so that relevant strains can be included in vaccine

  4. Constraints of subducted slabs under the Indian Ocean on the northward motion of India from Gondwanaland towards Eurasia

    We find an extensive swath of slabs in the lower mantle under the Indian Ocean at depths of 1000-2200km, with shallower slabs to the north under India and Eurasia at ~200-1500km. These slabs closely correspond to the well-known track that India has travelled northward from Gondwanaland toward its collision with Eurasia, viewed in the Indo-Atlantic moving hotspot reference frame, and account for a significant proportion of the predicted loss of the Ceno- and Neo-Tethyan Oceans since ~140Ma. Our work is based on our methodology of [1] mapping subducted slabs in global tomography (MITP08, Li et al. 2008) as 3D mid-slab surfaces in the Gocad environment, [2] quantitatively unfolding these surfaces to the surface of the earth in a spherical Earth model, minimizing changes in area and distortion, and [3] incorporating them into Gplates global plate tectonic reconstructions (http://www.earthbyte.org). These unfolded subducted slabs provide substantial quantitative constraints for the original location and extent of India and Greater India and for the nature and history of Ceno- and Neo-Tethys. We observe a distinct discontinuity in amplitude of p- and s-wave velocity anomalies between the higher-amplitude Neo-Tethyan slabs to the north under India and the Middle East and the lower-amplitude Ceno-Tethyan slabs under the central Indian Ocean, which is in agreement with a predicted large ~100Ma discontinuity in age-at-subduction between Neo- and Ceno-Tethys in existing plate-tectonic models (e.g. Müller et al., 2008; Seton et al, 2012). We present a plate tectonic reconstruction that incorporates these mapped slab constraints, with the implication that a substantial fraction of the Tethyan Ocean (~3000km) subducted southward under India at an early stage in the northward motion of India from Gondwanaland.

  5. Tectonics of north Himalaya in China since early Oligocene (Invited)

    NASA Astrophysics Data System (ADS)

    Zhang, J.

    2010-12-01

    The India-Asia collision resulted in the building-up of the huge Himalayan orogen, and the north Himalayan orogen began to experience extensional tectonics since Eocene-Oligocene transition (EOT), which formed such extensional structures as the south Tibet detachment system (STDS), the related north Himalayan gneiss domes (NHGD), and the north-south trending rifts (NSTR). The leucogranite intruding beneath the STDS caused by thickening-melting gives the youngest U-Pb age of about 35Ma, which is same to the oldest U-Pb age of the syn-kinematic leucogranite intruding along the STDS. This indicates a tectonic transformation from thickening to extension in north Himalaya when the STDS began to activate at EOT. The thickening before EOT caused the partial melting in middle-lower crust, which formed the weak root of the thickened crust or the so-called “channel flow”. This “channel flow” triggered the collapse of the orogen and the onset of the extensional tectonics of the STDS. There are similarities in main duration and geochemistry between the granitic magmatism along the STDS and that in the cores of the NHGDs, thus the formation of the NHGD has a direct relationship to the activity of the STDS. The STDS’s extension and the resultant thinning caused further partial melting of the crust, resulting in larger-scale emplacement of leucogranite in Miocene (27~13Ma). Diapirism of these plutons shaped the NHGD which exposed the greater Himalayan crystalline complex and the shear zones of the STDS in north Himalaya. In north Himalaya, the STDS was offset by the NSTRs, the STDS stopped deformation at about 13Ma when the NSTRs began to be active at the same time. This indicates another tectonic transformation in north Himalaya at about 13Ma, when the N-S extension of the STDS ceased and gave the way to E-W extension of the NSTRs, and the peak granitic magmatism in north Himalaya finished at this time. This change possibly represents the start of the eastward channel

  6. How poor are women in rural India?

    Rajuladevi, A K

    1992-07-01

    The assessment of poor women in India as dependent and exploited regardless of poverty focused strategies is reflected in this review of relevant literature. The scholarly approaches to the problems of poor women involve redirection and expansion of resources to women (increase bank credit) through policy and institutional changes, and involve improving women's welfare through changes in class and gender hierarchies; both pertain to restructuring power groups. A little ascribed to belief is that the organization of women's numbers will empower women; the constraints are stated. There is also some argument over whether to design women-specific programs or integrate women into existing programs; some examples are given of successes and difficulties. The regionalization of poverty in eastern and central India is discussed. The growth of the poor has been among the landless, wage-dependent households. 9.6% of households (7.5 million) are headed by women. Women work fewer hours and at lower wage scales and have fewer employment opportunities. Lower earnings are coupled with differentials in demand for female and male labor in agriculture and a crowded labor market. There is a concentration of women in less visible, nonmonetary subsistence production and domestic work. Women are undercounted in employment studies. Women predominate in agricultural activity. Women's status is influenced by economic status, caste, and ethnic background. Domestic work increases status for women and households. The poorer households have greater labor force participation, particularly as wage laborers rather than unpaid family workers. Regional factors affecting rural household strategies are factors affecting the economy (topography, rainfall, climate) and the degree of development, plus sociocultural variables (kinship and religious beliefs which affect the social domain of women), and the degree of dependence on hired vs. family labor. There are sharp contrasts in the value and survival

    The Indian subcontinent is characterized by the ancestral and cultural diversity of its people. Genetic input from several unique source populations and from the unique social architecture provided by the caste system has shaped the current genetic landscape of India. In the present study 200 individuals each from three upper-caste and four middle-caste Hindu groups and from two Muslim populations in North India were examined for 10 polymorphic Alu insertions (PAIs). The investigated PAIs exhibit high levels of polymorphism and average heterozygosity. Limited interpopulation variance and genetic flow in the present study suggest admixture. The results of this study demonstrate that, contrary to common belief, the caste system has not provided an impermeable barrier to genetic exchange among Indian groups.

  8. Genetic analysis of HIV-1 Circulating Recombinant Form 02_AG, B and C subtype-specific envelope sequences from Northern India and their predicted co-receptor usage

    PubMed Central

    2009-01-01

    HIV-1 epidemic in India is largely driven by subtype C but other subtypes or recombinants have also been reported from several states of India. This is mainly due to the co-circulation of other genetic subtypes that potentially can recombine to generate recombinant/mosaic genomes. In this study, we report detail genetic characterization of HIV-1 envelope sequences from North India (Delhi and neighboring regions). Six of 13 were related to subtype C, one B and the rest six showed relatedness with CRF02_AG strain. The subtype C possessed the highly conserved GPGQ motif but subtype B possessed the GPGR motif in the V3 loop as observed earlier. While most of the sequences suggested CCR5 co-receptor usage, one subtype C sample clearly indicated CXCR4 usage. A successful mother to child transmission was established in two pairs. Thus, co-circulation of multiple subtypes (B and C) and the recombinant CRF02_AG strains in North India suggests a rapidly evolving scenario of HIV-1 epidemic in this region with impact on vaccine formulation. Since this is the first report of CRF02_AG envelope from India, it will be important to monitor the spread of this strain and its impact on HIV-1 transmission in India. PMID:19954551

    The Indian Ocean tsunami (IOT) devastated several countries of North Indian Ocean. India is one of the worst affected countries after Indonesia and Sri Lanka. In India, Tamil Nadu suffered maximum with fatalities exceeding 8,000 people. Historical records show that tsunami has invaded the shores of Tamil Nadu in the past and has made people realize that the tsunami threat looms over Tamil Nadu and it is necessary to evolve strategies for tsunami threat management. The IOT has brought to light that tsunami inundation and runup varied within short distances and for the disaster management for tsunami, large scale maps showing areas that are likely to be affected by future tsunami are identified. Therefore threat assessment for six villages including Mamallapuram (also called Mahabalipuram) which is famous for its rock-cut temples, from the northern part of Tamil Nadu state of India has been carried out and threat maps categorizing the coast into areas of different degree of threat are prepared. The threat was assessed by numerical modeling using TUNAMI N2 code considering different tsunamigenic sources along the Andaman - Sumatra trench. While GEBCO and C-Map data was used for bathymetry and for land elevation data was generated by RTK - GPS survey for a distance of 1 km from shore and SRTM for the inland areas. The model results show that in addition to the Sumatra source which generated the IOT in 2004, earthquakes originating in Car Nicobar and North Andaman can inflict more damage. The North Andaman source can generate a massive tsunami and an earthquake of magnitude more than Mw 9 can not only affect Tamil Nadu but also entire south east coast of India. The runup water level is used to demarcate the tsunami threat zones in the villages using GIS.

    The WHO officially certifies India and other countries of the South East Asian regions as free of guinea worm disease. The eradication was made possible through the efforts of the Indian government to launch a national guinea worm eradication program in 1983-84, and a sustained campaign at the grass-roots level by agencies such as the UN International Children's Fund and the WHO in collaboration with the government. The recognition was based on the report gathered by three members of the 4th International Commission for Certification of Dracunculiasis Eradication, who visited India in November 1999 and conducted an investigation in 62 villages in 5 states where the disease had been endemic. Also, the national eradication program had been evaluated 7 times and showed remarkable achievement.

    The timing of India-Asia collision is critical to the understanding of crustal deformation processes, since, for example, it impacts on calculations regarding the amount of convergence that needs to be accommodated by various mechanisms. In this research we use sediments originally deposited in the Tethyan ocean basin and now preserved in the Himalayan orogeny to constrain the timing of collision. In the NW Himalaya, a number of workers have proposed a ca 55-50 Ma age for collision along the Indus suture zone which separates India from the Kohistan-Ladakh Intraoceanic Island arc (KLA) to the north. This is based on a number of factors including the age of youngest marine sediments in the Indus suture (e.g. Green et al. 2008), age of eclogites indicative of onset of Indian continental subduction (e.g. de Sigoyer et al. 2000), and first evidence of detritus from north of the suture zone deposited on the Indian plate (e.g. Clift et al. 2002). Such evidence can be interpreted as documenting the age of India-Asia collision if one takes the KLA to have collided with the Asian plate prior to its collision with India (e.g. Petterson 2010 and refs therein). However, an increasing number of workers propose that the KLA collided with Asia subsequent to its earlier collision with India, dated variously at 85 Ma (Chatterjee et al. 2013), 61 Ma (Khan et al. 2009) and 50 Ma (Bouilhol et al. 2013). This, plus the questioning of earlier provenance work (Clift et al. 2002) regarding the validity of their data for constraining timing of earliest arrival of material north of the suture deposited on the Indian plate (Henderson et al. 2011) suggests that the time is right for a reappraisal of this topic. We use a provenance-based approach here, using combined U-Pb and Hf on detrital zircons from Tethyan ocean basin sediments, along with petrography and biostratigraphy, to identify first arrival of material from north of the Indian plate to arrive on the Indian continent, to constrain

    India has embarked upon a very ambitious program in biotechnology with a view to harnessing its available human and unlimited biodiversity resources. It has mainly been a government sponsored effort with very little private industry participation in investment. The Department of Biotechnology (DBT) established under the Ministry of Science and Technology in 1986 was the major instrument of action to bring together most talents, material resources, and budgetary provisions. It began sponsoring research in molecular biology, agricultural and medical sciences, plant and animal tissue culture, biofertilizers and biopesticides, environment, human genetics, microbial technology, and bioprocess engineering, etc. The establishment of a number of world class bioscience research institutes and provision of large research grants to some existing universities helped in developing specialized centres of biotechnology. Besides DBT, the Department of Science & Technology (DST), also under the Ministry of S&T, sponsors research at universities working in the basic areas of life sciences. Ministry of Education's most pioneering effort was instrumental in the creation of Biochemical Engineering Research Centre at IIT Delhi with substantial assistance from the Swiss Federal Institute of Technology, Zurich, Switzerland to make available state-of-the-art infrastructure for education, training, and research in biochemical engineering and biotechnology in 1974. This initiative catalysed biotechnology training and research at many institutions a few years later. With a brief introduction, the major thrust areas of biotechnology development in India have been reviewed in this India Paper which include education and training, agricultural biotechnology, biofertilizers and biopesticides, tissue culture for tree and woody species, medicinal and aromatic plants, biodiversity conservation and environment, vaccine development, animal, aquaculture, seri and food biotechnology, microbial

  16. AIDS in India: constructive chaos?

    1991-08-01

    Until recently, the only sustained AIDS activity in India has been alarmist media attention complemented by occasional messages calling for comfort and dignity. Public perception of the AIDS epidemic in India has been effectively shaped by mass media. Press reports have, however, bolstered awareness of the problem among literate elements of urban populations. In the absence of sustained guidance in the campaign against AIDS, responsibility has fallen to voluntary health activists who have become catalysts for community awareness and participation. This voluntary initiative, in effect, seems to be the only immediate avenue for constructive public action, and signals the gradual development of an AIDS network in India. Proceedings from a seminar in Ahmedabad are discussed, and include plans for an information and education program targeting sex workers, health and communication programs for 150 commercial blood donors and their agents, surveillance and awareness programs for safer blood and blood products, and dialogue with the business community and trade unions. Despite the lack of coordination among volunteers and activists, every major city in India now has an AIDS group. A controversial bill on AIDS has ben circulating through government ministries and committees since mid-1989, a national AIDS committee exists with the Secretary of Health as its director, and a 3-year medium-term national p
