    The Early Precambrian sequence in Karnataka, South India provides evidences for a distinct trend of evolution which differs from trends exhibited in many other Early Precambrian regions of the world. The supracrustal rock associations preserved in greenstone belts and as inclusions in gneisses and granulites suggest the evolution of the terrain from a stable to a mobile regime. The stable regime is represented by (1) layered ultramafic-mafic complexes, (2) orthoquartzite-basalt-rhyodacite-iron formation, and (30 ortho-quartzite-carbonate-Mn-Fe formation. The mobile regime, which can be shown on sedimentological grounds to have succeeded the stable regime, witnessed the accumulation of a greywacke-pillow basalt-dacite-rhyolite-iron formation association. Detrital sediments of the stable zone accumulated dominantly in fluvial environment and the associated volcanics are ubaerial. The volcanics of the stable regime are tholeiites derived from a zirconium and LREE-enriched sources. The greywackes of the mobile regime are turbidities, and the volcanic rocks possess continental margin (island-arc or back-arc) affinity; they show a LREE depleted to slightly LREE-enriched pattern. The evolution from a stable to a mobile regime is in contrast to the trend seen in most other regions of the world, where an early dominantly volcanic association of a mobile regime gives way upward in the sequence to sediments characteristic of a stable regime.

  3. Prospects for better nutrition in India.

    Being home to 31% of the world's children who are stunted and 42% of those who are underweight, and with many children and adults affected by micronutrient deficiencies, India is facing huge challenges in the field of nutrition. Even though the Indian Government is investing vast amounts of money into programs that aim to enhance food security, health and nutrition (the Integrated Child Development Services program alone costs 3 billion USD per year), overall impact has been rather disappointing. However, there are some bright spots on the horizon. The recent District Level Health Surveys (DLHS-4) do show significant progress, ie a reduction in stunting of around 15% over the past 6 years in a few states for which preliminary results are available. The reasons for this reduction are not unambiguous and appear to include state government commitment, focus on the 'window of opportunity', improved status and education of women, a lowered fertility rate, and combinations of nutrition- specific and nutrition-sensitive interventions. Apart from the government many other agencies play a role in driving improvements in nutrition. Since 2006 the Global Alliance for Improved Nutrition (GAIN) has worked with a range of partners to improve access to nutritious foods for large parts of the population, through public and private delivery channels. This supplement presents a selection of these activities, ranging from a capacityassessment of frontline workers in the ICDS system, large scale staple food fortification, salt iodization, fortification of mid-day meals for school children and decentralized complementary food production.

  4. The evolution of alcohol use in India.

    This paper traces the role of alcohol production and use in the daily lives of people in India, from ancient times to the present day. Alcohol use has been an issue of great ambivalence throughout the rich and long history of the Indian subcontinent. The behaviors and attitudes about alcohol use in India are very complex, contradictory and convoluted because of the many different influences in that history. The evolution of alcohol use patterns in India can be divided into four broad historical periods (time of written records), beginning with the Vedic era (ca. 1500-700 BCE). From 700 BCE to 1100 CE, ("Reinterpretation and Synthesis") is the time of emergence of Buddhism and Jainism, with some new anti-alcohol doctrines, as well as post-Vedic developments in the Hindu traditions and scholarly writing. The writings of the renowned medical practitioners, Charaka and Susruta, added new lines of thought, including arguments for "moderate alcohol use." The Period of Islamic Influence (1100-1800 CE), including the Mughal era from the 1520s to 1800, exhibited a complex interplay of widespread alcohol use, competing with the clear Quranic opposition to alcohol consumption. The fourth period (1800 to the present) includes the deep influence of British colonial rule and the recent half century of Indian independence, beginning in 1947. The contradictions and ambiguities-with widespread alcohol use in some sectors of society, including the high status caste of warriors/rulers (Kshatriyas), versus prohibitions and condemnation of alcohol use, especially for the Brahmin (scholar-priest) caste, have produced alcohol use patterns that include frequent high-risk, heavy and hazardous drinking. The recent increases in alcohol consumption in many sectors of the general Indian population, coupled with the strong evidence of the role of alcohol in the spread of HIV/STI infections and other health risks, point to the need for detailed understanding of the complex cross

    The discipline of astrobiology includes the dynamics of biological evolution. One of the major ways that the cosmos influences life is through the catastrophic environmental disruptions caused when comets and asteroids collide with a planet. We now recognize that such impacts have caused mass extinctions and played a major role in determining the evolution of life on Earth. The time-averaged impact flux as a function of projectile energy can be derived from lunar cratering statistics as well as the current population of near Earth asteroids (NEAs). Effects of impacts of various energies can be modeled, using data from historic impacts [such as the Cretaceous-Tertiary (KT) impactor 65 million years ago] and the observed 1994 bombardment of Jupiter by fragments of Comet Shoemaker-Levy 9. It is of particular interest to find from such models that the terrestrial environment is highly vulnerable to perturbation from impacts, so that even such a small event as the KT impact (by a projectile 10-15 km in diameter) can lead to a mass extinction. Similar considerations allow us to model the effects of still smaller (and much more likely) impacts, down to the size of the asteroid that exploded over Tunguska in 1908 (energy approximately 10 megatons). Combining the impact flux with estimates of environmental and ecological effects reveals that the greatest contemporary hazard is associated with impactors near 1 million megatons in energy (approximately 2 km in diameter for an asteroid). The current impact hazard is significant relative to other natural hazards, and arguments can be developed to illuminate a variety of public policy issues. The first priority in any plan for defense against impactors is to survey the population of Earth-crossing NEAs and project their orbits forward in time. This is the purpose of the Spaceguard Survey, which has already found more than half of the NEAs >1 km in diameter. If there is an NEA on a collision course with Earth, it can be

    Background India and the EU are currently negotiating a Trade and Investment Agreement which also covers services. This paper examines the opportunities for and constraints to India-EU relations in health services in the context of this agreement, focusing on the EU as a market for India's health services exports and collaboration. The paper provides an overview of key features of health services in the EU and India and their bearing on bilateral relations in this sector. Methods Twenty six semi-structured, in-person, and telephonic interviews were conducted in 2007-2008 in four Indian cities. The respondents included management and practitioners in a variety of healthcare establishments, health sector representatives in Indian industry associations, health sector officials in the Indian government, and official representatives of selected EU countries and the European Commission based in New Delhi. Secondary sources were used to supplement and corroborate these findings. Results The interviews revealed that India-EU relations in health services are currently very limited. However, several opportunity segments exist, namely: (i) Telemedicine; (ii) Clinical trials and research in India for EU-based pharmaceutical companies; (iii) Medical transcriptions and back office support; (iv) Medical value travel; and (v) Collaborative ventures in medical education, research, training, staff deployment, and product development. However, various factors constrain India's exports to the EU. These include data protection regulations; recognition requirements; insurance portability restrictions; discriminatory conditions; and cultural, social, and perception-related barriers. The interviews also revealed several constraints in the Indian health care sector, including disparity in domestic standards and training, absence of clear guidelines and procedures, and inadequate infrastructure. Conclusions The paper concludes that although there are several promising areas for India

  9. Life history evolution: successes, limitations, and prospects

    Stearns, Stephen C.

    Life history theory tries to explain how evolution designs organisms to achieve reproductive success. The design is a solution to an ecological problem posed by the environment and subject to constraints intrinsic to the organism. Work on life histories has expanded the role of phenotypes in evolutionary theory, extending the range of predictions from genetic patterns to whole-organism traits directly connected to fitness. Among the questions answered are the following: Why are organisms small or large? Why do they mature early or late? Why do they have few or many offspring? Why do they have a short or a long life? Why must they grow old and die? The classical approach to life histories was optimization; it has had some convincing empirical success. Recently non-equilibrium approaches involving frequency-dependence, density-dependence, evolutionary game theory, adaptive dynamics, and explicit population dynamics have supplanted optimization as the preferred approach. They have not yet had as much empirical success, but there are logical reasons to prefer them, and they may soon extend the impact of life history theory into population dynamics and interspecific interactions in coevolving communities.

    Discusses the indigenization movement of psychology in India, which attempts to develop a context sensitive discipline that can understand the concept of mind and human behavior from the cultural perspective. It emphasizes the culturally bound aspects of human nature and uses methods to explore the ways in which culture emerges from history. Given the directions of scientific research, it is not absurd to engage with Western theories. Nevertheless, some Indian psychologists have resisted what they consider the intrusion of modern psychology. They have forwarded premises about human nature in the philosophical roots of traditional Indian thought which look tautological and feed back to our oppressive social structures; for example, the patriarchy and caste systems. The scope of social change is limited under the garb of indigenization, unless the movement of indigenization calls for social change. Several points are made, of which Indian psychological approaches should become cognizant to better understand the relevant contexts for social responsibility. In addition, several recommendations are suggested for a new wave of psychological research in India. (PsycINFO Database Record

    Cervical cancer is the most common cancer and a leading cause of cancer deaths among women in developing countries. The disease is caused due to persistent infection of one or more of about 15 high-risk human papillomaviruses (HR-HPVs), most commonly by HPV types 16/18. In India, over 98% of cervical cancer cases harbor HPV infection and HPV 16 is the type exclusively (80-90%) prevalent. Unlike the West, HPV infection is most common in women in their third decade (26-35 years) of sexual activity and invasive cancer also arises much later with a peak at about 45-55 years of age. Recently, two successful prophylactic HPV vaccines, a quadrivalent (HPV16/18/6/11) 'Gardasil' by Merck and a bivalent (HPV16/18) 'Cervarix' by GSK have been developed. Several other approaches including plant-based edible, pentameric capsomere-based intranasal and DNA-based vaccines have also been employed to develop prophylactic vaccines. Also, several therapeutic vaccines either protein/peptide based or DNA based are in clinical trials but are yet to establish their efficacy. Though there are several issues regarding implementation of the already developed vaccines in resource limited countries, efforts are being made to develop cost-effective second-generation vaccines. If cost minimized, HPV related new technologies involved in screening tests and vaccines are expected to reduce incidence of cervical cancer and deaths it causes in women from developing countries.

The Transplantation of Human Organ Act and rules in India were promulgated in 1994 and subsequently amended in 2008 and 2011 to promote organ transplantation, including deceased organ donation, commensurate with the highest ethical principles. We have reviewed in brief the origin and evolution of the Transplantation of Human Organ Act in India with the hope that our experience in developing the laws that govern organ transplantation may be of value for others undertaking or overseeing this life-giving advance.

  13. Rifting to India-Asia Reactivation: Multi-phase Structural Evolution of the Barmer Basin, Rajasthan, northwest India

    The Barmer Basin, situated within the West Indian Rift System, is an intra-cratonic rift basin produced during Gondwana break-up. Despite being a prominent oil and gas province, the structural evolution and context of the rift within northwest India remains poorly understood. Substantial subsurface datasets acquired during hydrocarbon exploration provide an unrivalled tool to investigate the tectonic evolution of the Barmer Basin rift and northwest India during India-Asia collision. Here we present a structural analysis using seismic datasets to investigate Barmer Basin evolution and place findings within the context of northwest India development. Present day rift structural architectures result from superposition of two non-coaxial extensional events; an early mid-Cretaceous rift-oblique event (NW-SE), followed by a main Paleocene rifting phase (NE-SW). Three phases of fault reactivation follow rifting: A transpressive, Late Paleocene inversion along localised E-W and NNE-SSW-trending faults; a widespread Late Paleocene-Early Eocene inversion and Late Miocene-Present Day transpressive strike-slip faulting along NW-SE-trending faults and isolated inversion structures. A major Late Eocene-Miocene unconformity in the basin is also identified, approximately coeval with those identified within the Himalayan foreland basin, suggesting a common cause related to India-Asia collision, and calling into question previous explanations that are not compatible with spatial extension of the unconformity beyond the foreland basin. Although, relatively poorly age constrained, extensional and compressional events within the Barmer Basin can be correlated with regional tectonic processes including the fragmentation of Gondwana, the rapid migration of the Greater Indian continent, to subsequent collision with Asia. New insights into the Barmer Basin development have important implications not only for ongoing hydrocarbon exploration but the temporal evolution of northwest India.

    In 1966 the government of India announced a new national population policy that eliminated numerical targets for new contraceptive acceptors. This paper examines the history of target setting in India and factors that led to the elimination of targets. The analysis is based on published and unpublished reports on India's population policy and the family planning programme and interviews with senior Indian and foreign officials and population specialists. Five factors are identified as playing a role in the evolution from target setting to a target-free policy:(1) the research of India's academics; (2) the work of women's health advocates; (3) the support of officials in the state bureaucracy who approved the target-free approach; (4) the influence of the donors to India's family planning programme, especially the World Bank; and (5) the International Conference on Population and Development.

    2010-05-01

    The Proterozoic Aravalli orogen in the state of Rajasthan, northwestern India, constitutes the most important metallogenic province for base-metal deposits in India and hosts the entire economically viable lead-zinc resource-base of the country. The orogen evolved through near-orderly Wilson cycles of repeated extensional and compressional tectonics resulting in sequential opening and closing of intracratonic rifts and amalgamation of crustal domains during a circa 1.0-Ga geological history from 2.2 Ga to 1.0 Ga. This study develops a conceptual tectonostratigraphic model of the orogen based on a synthesis of the available geological, geophysical and geochronological data followed by deep-seismic-reflectivity-constrained 2-D forward gravity modeling, and links it to the Proterozoic base-metal metallogeny in the orogen in order to identify key geological controls on the base-metal mineralization. These controls are translated into exploration criteria for base-metal deposits, validated using empirical spatial analysis, and used to derive input spatial variables for model-based base-metal prospectivity mapping of the orogen. A support vector machine (SVM) algorithm augmented by incorporating a feature selection procedure is used in a GIS environment to implement the prospectivity mapping. A comparison of the SVM-derived prospectivity map with the ones derived using other established models such as neural-networks, logistic regression, and Bayesian weights-of-evidence indicates that the SVM outperforms other models, which is attributed to the capability of the SVM to return robust classification based on small training datasets.

    Although some studies suggested specific foods/beverages as risk factors for travellers' diarrhoea (TD), details of transmission remain unclear. We assessed the influence of travel style (luxury/middle-class versus backpacking) on TD risk. TD attack rates were compared in a prospective study among travellers to India at the University of Zurich's Travel Clinic. Information on consumption of foods/beverages was collected. Seventy-one luxury/middle-class travellers and 21 backpackers completed the study; overall 37% suffered from TD (62% backpackers, 30% luxury/middle-class travellers, OR 4.43, p 0.022). Travel style rather than the consumption of specific foods/beverages appears to be a risk factor for TD development.

    The Douala Basin is a stable Atlantic-type, predominantly offshore basin and forms the northern terminal of a series of divergent passive margin basins located on the Southwest coast of Africa that resulted from the rifting of Africa from South America. An integration of new studies including detailed well, biostratigraphic, sedimentological, geochemical and seismic data has confirmed that the tectonostratigraphic evolution in the basin can be broadly divided into three developmental phases: the Syn-rift, Transitional and Drift phases. This basis has been explored intermittently for hydrocarbon for the past 40 years with two important gas fields discovered and no commercial oil found as yet. This early gas discovery and a corresponding lack of any significant oil discovery, led early operators to term this basin as essentially a gas province. However, recent geochemical analyses of various oil-seeps and oil samples from various localities in the basin, using state-of-the-art techniques have demonstrated that this basin is a potential oil prone basin. The results show that two models of oil sourcing are possible: a Lower Cretaceous lacustrine saline source, similar to the presalt basins of Gabon or a marine Upper Cretaceous to lower Tertiary source, similar to the neighbouring Rio del Rey/Niger Delta Complex. Additionally, seismic reflection data also demonstrate a variety of reservoir horizons, including submarine fans, channel-like features and buried paleohighs, all interbedded within regionally extensive, uniformity bounded mudstone units. Hence, it is now quite evident that within this basin, there exist a vast potential for a wide variety of stratigraphic, structural and combined traps. These features, which are considered to have significantly enhanced the prospectivity of this basin, will be discussed in this paper.

    The economic, technical, and agricultural aspects of equiping poor farmers in India with windpowered pumps were analyzed. It is concluded that the prospects for a market for windmills among nontarget group farmers (especially big farmers with diesel pumps) are better than the prospects among the target group farmers. Continuation of the project might lead to an improvement of the situation for the richer farmers, which would in turn lead to a decline in the situation of the original target group of the project, the small and marginal farmers.

    Despite the prevalence of Newcastle disease virus (NDV) outbreaks in India through the decades, there has been little genetic characterisation of the virulent strains circulating in Northeast India. In 2014, a poultry farm in the Kamrup district of Assam reported an ND outbreak. In this study, genetic analysis and clinicopathological tests showed the virulent nature of the isolate Kamrup. Based on prudent classification criteria, the virulent strain Kamrup was found to be most closely related to members of genotype XIII of class II NDV. A phylogenetic analysis of NDV strains suggested three sub-genotypes: XIIIa, XIIIb and XIIIc. NDV strain Kamrup belonged to sub-genotype XIIIc. Sub-genotype XIIIc isolates were similar to the 1982 isolate from cockatoo and appeared to have evolved parallel to the preceding genotype XIII viruses circulating in India. The high genetic diversity and frequency of mutations observed in the envelope glycoproteins of strain Kamrup demonstrate the evolution of the pandemic genotype XIII NDV in India, which further undermines and complicates of NDV management in India.

    The association of iodine with organic matter in sedimentary basins is well documented. High iodine concentration in soils overlying oil and gas fields and areas with hydrocarbon microseepage has been observed and used as a geochemical exploratory tool for hydrocarbons in a few studies. In this study, we measure iodine concentration in soil samples collected from parts of Deccan Syneclise in the west central India to investigate its potential application as a geochemical indicator for hydrocarbons. The Deccan Syneclise consists of rifted depositional sites with Gondwana-Mesozoic sediments up to 3.5 km concealed under the Deccan Traps and is considered prospective for hydrocarbons. The concentration of iodine in soil samples is determined using ICP-MS and the values range between 1.1 and 19.3 ppm. High iodine values are characteristic of the northern part of the sampled region. The total organic carbon (TOC) content of the soil samples range between 0.1 and 1.3%. The TOC correlates poorly with the soil iodine (r{sup 2} < 1), indicating a lack of association of iodine with the surficial organic matter and the possibility of interaction between the seeping hydrocarbons and soil iodine. Further, the distribution pattern of iodine compares well with two surface geochemical indicators: the adsorbed light gaseous hydrocarbons (methane through butane) and the propane-oxidizing bacterial populations in the soil. The integration of geochemical observations show the occurrence of elevated values in the northern part of the study area, which is also coincident with the presence of exposed dyke swarms that probably serve as conduits for hydrocarbon microseepage. The corroboration of iodine with existing geological, geophysical, and geochemical data suggests its efficacy as one of the potential tool in surface geochemical exploration of hydrocarbons. Our study supports Deccan Syneclise to be promising in terms of its hydrocarbon prospects.

    Sickle cell anemia, the homozygous genotype of sickle cell disease is one of the most common heritable diseases in the world. The Arab-Asian haplotype present in India is one of the least severe of all haplotypes. Many sickle cell anemia patients are now leading a symptom-free productive life due to hydroxyurea (HU) and better supportive care. Although pregnancy in sickle cell anemia patients is considered a high-risk category, it perinatal outcome is least studied, particularly among carriers of the Arab-Asian haplotype. Thus, the present prospective, randomized study was performed to assess the perinatal outcome in sickle cell anemia. Neonatal outcome such as low birth weight, perinatal mortality rate, special care newborn unit (SCNU) admission, intrauterine growth retardation (IUGR) and pre term births were significantly higher in sickle cell anemia mothers. Maternal outcome such as severe anemia, preeclampsia, vasoocclusive crisis (VOC), pulmonary complications, jaundice and blood transfusion requirements were significantly higher in sickle cell anemia mothers, which were successfully managed. Cesarian section rate was not significantly different from normal controls. Successful pregnancies were achieved in 84.44% of cases. However, we strongly recommend that pregnancies in these patients should be managed in an institutional setup.

    Thermal anomalies associated with ore-mineralization (Pb-Cu-Zn and Fe) were studied using thermal infrared data collected over Mamandur polymetal prospect, India, with the aid of satellite, field, and laboratory measurements. Day and night ASTER data were analysed in conjunction with field measurements to estimate thermal inertia of the ore body, altered zones and country rocks. Representative samples collected from field were also analysed for thermal conductivity, diffusivity, and inertia using a self-fabricated setup. Spatial changes in thermal inertia were mapped by look up table (LUT) and advanced thermal inertia mapping (ATIM) approaches. Mineralized zones show very high thermal contrast (ΔT) both in field (15-25°C) and satellite data (14.9-16.9oC). They also exhibit the lowest thermal inertia in field-(2118-5474 J m-2 K-1 s-1/2) and satellite-based (3783-4037 J m-2 K-1 s-1/2) measurements. In non-mineralized areas, acidic rocks (granite, migmatite and granite gneiss) have lower inertia than basic rocks (basic granulite, dolerite and charnockite). Results estimated by LUT and ATIM approaches correlate very well at satellite (R2 = 0.97) and field (R2 = 0.89) scales. Similarly, field- and satellite-based results also have good correlation (R2 = 0.69-0.72). This study illustrates the potential of thermal inertia mapping in delineating ore bodies and deciphering the lithological changes even under veneer of soil.

    The Peninsular Gneisses of Southern India developed over a period of several hundred Ma in the middle-to-late Archaean. Gneisses in the Gorur-Hassan area of southern Karnataka are the oldest recognized constituents: Beckinsale et al. reported a preliminary Rb-Sr whole-rock isochron age of 33558 + or - 66 Ma, but further Rb-Sr and Pb/Pb whole-rock isochron determinations indicate a slightly younger, though more precise age of ca 3305 Ma (R. D. Beckinsale, Pers. Comm.). It is well established that the Peninsular Gneisses constitute basement on which the Dharwar schist belts were deposited. Well-documented exposures of unconformities, with basal quartz pebble conglomerates of the Dharwar Supergroup overlying Peninsular Gneisses, have been reported from the Chikmagalur and Chitradurga areas, and basement gneisses in these two areas have been dated by Rb-Sr and Pb/Pb whole-rock isochron methods at ca 3150 Ma and ca 3000 Ma respectively. Dharwar supracrustal rocks of the Chitradurga schist belt are intruded by the Chitradurga Granite, dated by a Pb/Pb whole-rock isochron at 2605 + or - 18 Ma. These results indicate that the Dharwar Supergroup in the Chitradurga belt was deposited between 3000 Ma and 2600 Ma.

    Krishna Godavari (K.G.) basin is a passive margin basin developed along the Eastern coast of India. This basin has a polyhistoric evolution with multiple rift systems. Rift basin exploration has provided the oil and gas industry with almost one third of discovered global hydrocarbon resources. Understanding synrift sequences, their evolution, depositional styles and hydrocarbon prospectivity has become important with recent discovery of the wells, G-4-6,YS-AF and KG-8 in the K.G. offshore basin. The East Godavari subbasin is a hydrocarbon producing basin from synrift and pre-rift sediments, and hence this was selected as the study area for this research. The study has been carried out by utilizing data of around 58 wells (w1-w58) drilled in the study area 25 of which are hydrocarbon bearing with organic thickness varying from 200 m to 600 m. Age data generated by palaentology and palynology studies have been utilized for calibration of key well logs to differentiate between formations within prerift and synrift sediments. The electrologs of wells like resistivity, gamma ray, neutron, density and sonic logs have been utilized for correlation of different formations in all the drilled wells. The individual thicknesses of sand, shale and coal in the formations have been calculated and tabulated. For Golapalli formation, the isopach and isolith maps were generated which revealed that there were four depocentres with input from the north direction. Schematic geological cross sections were prepared using the well data and seismic data to understand the facies variation across the basin. The sedimentological and petrophysical analysis reports and electro log suites were referred to decipher the environment of deposition, the reservoir characteristics, and play types. The geochemical reports [w4 (Tmax)= 455-468 °C; w1 (Tmax) = 467-514 °C; w4(VRO)= 0.65-0.85; w1(VRO)= 0.83-1.13] revealed the source facies, its maturation and migration timings i.e. the petroleum systems

    The Garnet subsalt prospect in the East Cameron, South Addition area of offshore Louisiana was acquired by Anadarko Petroleum Corporation in the 1994 offshore Louisiana federal lease sale. The prospect is a structural closure beneath a rugose and highly deformed allochthonous salt sheet. This salt geometry has distorted the seismic image below it, making necessary the use of more elaborate and costly seismic depth imaging techniques. The prospect is further complicated by the lack of proximate deep well control to aid in predicting stratigraphy below salt. In this paper, we present the progressive stages of prospect evaluation leading to the current interpretation, beginning first with the initial lease sale identification of the prospect. Through the various stages of evaluation, geophysical efforts have reflected an attempt to balance time and costs with the anticipated benefits. Seismic evaluation has progressed from various 2D methods through 3D time migration, 3D post-stack depth migration and ultimately to 3D pre-stack depth migration. The primary goal of the 3D pre-stack depth migration was to image below salt and considerable effort has been expended in deriving an accurate velocity model for the final depth migration. The improved imaging of the various salt bodies has produced a more accurate picture of the salt geometries and subsalt structures. From this, we have reconstructed the salt movement within the prospect area and have inferred salt tectonic and sedimentation interrelationships.

    Transcatheter Aortic Valve Implantation (TAVI) is a well-described treatment for symptomatic calcific severe aortic stenosis. However, TAVI technology is being increasingly used around the world to treat selected cases of severe aortic regurgitation (AR). One of the main limitations of using TAVI technology for AR is the lack of calcification, which is common in such cases. This makes anchoring of a TAVI prosthesis to the aortic annulus difficult and risks displacement or embolization. However, with the availability of recapturable and repositionable TAVI technologies, these limitations have been overcome to a large extent. This is the first Corevalve Evolut R device that was used in India and the first TAVI to treat AR in India.

    Since the days of Darwin, scientists have used the framework of the theory of evolution to explore the interconnectedness of life on Earth and adaptation of organisms to the ever-changing environment. The advent of molecular biology has advanced and accelerated the study of evolution by allowing direct examination of the genetic material that ultimately determines the phenotypes upon which selection acts. The study of evolution has been furthered through examination of microbial evolution, with large population numbers, short generation times, and easily extractable DNA. Such work has spawned the study of microbial biogeography, with the realization that concepts developed in population genetics may be applicable to microbial genomes (Martiny et al., 2006; Manhes and Velicer, 2011). Microbial biogeography and adaptation has been examined in many different environments.

    Investigating changes in terrestrial water storage (TWS) is important for understanding response of the hydrological cycle to recent climate variability worldwide. This is particularly critical in India where the current economic development and food security greatly depend on its water resources. We use 129 monthly gravity solutions from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites for the period of January 2003 to May 2014 to characterize spatiotemporal variations of TWS and groundwater storage (GWS). The spatiotemporal evolution of GRACE data reflects consistent patterns with that of several hydroclimatic variables and also shows that most of the water loss has occurred in the northern parts of India. Substantial GWS depletion at the rate of 1.25 and 2.1 cm yr-1 has taken place, respectively in the Ganges Basin and Punjab state, which are known as the India's grain bowl. Of particular concern is the Ganges Basin's storage loss in drought years, primarily due to anthropogenic groundwater withdrawals that sustain rice and wheat cultivation. We estimate these losses to be approximately 41, 44, and 42 km3 in 2004, 2009, and 2012, respectively. The GWS depletions that constitute about 90% of the observed TWS loss are also influenced by a marked rise in temperatures since 2008. A high degree of correspondence between GRACE-derived GWS and in situ groundwater levels from observation well validates the results. This validation increases confidence level in the application of GRACE observations in monitoring large-scale storage changes in intensely irrigated areas in India and other regions around the world.

    Evidence regarding the relationship between married women's autonomy and risk of marital violence remains mixed. Moreover, studies examining the contribution of specific aspects of women's autonomy in influencing the risk of marital violence using measures of autonomy that incorporate its dynamic nature are rare. We investigated the relationship between women's autonomy and their experience of marital violence in rural India using prospective data. We used data on 4,904 rural women drawn from two linked studies: the NFHS-2, conducted during 1998-1999 and a follow-up study for a subgroup of women carried out during 2002-2003. Three dimensions of autonomy were used: financial autonomy, freedom of movement, and household decision-making. Marital violence was measured as experience of physical violence in the year prior to the follow-up survey. Findings indicate the protective effects of financial autonomy and freedom of movement in reducing the risk of marital violence in the overall model. Furthermore, region-wise analysis revealed that in the more gender equitable settings of south India, financial autonomy exerted a protective influence on risk of marital violence. However, in the more gender-stratified settings of north India, none of the dimensions of autonomy were found to have any protective effect on women's risk of marital violence. Results argue for an increased focus on strategies aimed at improving women's financial status through livelihood skill-building opportunities, development of a strong savings orientation, and asset-building options.

    The prevalence of physical domestic violence--violence against women perpetrated by husbands--is staggeringly high across the Indian subcontinent. Although gender-based power dynamics are thought to underlie women's vulnerability, relatively little is known about risk and protective factors. This prospective study in southern India examined the association between key economic aspects of gender-based power, namely spousal employment status, and physical domestic violence. In 2005-2006, 744 married women, aged 16-25, residing in low-income communities in Bangalore, India were enrolled in the study. Data were collected at enrollment, 12 and 24 months. Multivariable logistic regression models were used to examine the prospective association between women's employment status, their perceptions of their husband's employment stability, and domestic violence. Women who were unemployed at one visit and began employment by the next visit had an 80% higher odds of violence, as compared to women who maintained their unemployed status. Similarly, women whose husbands had stable employment at one visit and newly had difficulty with employment had 1.7 times the odds of violence, as compared to women whose husbands maintained their stable employment. To our knowledge, this study is the first from a developing country to confirm that changes in spousal employment status are associated with subsequent changes in violence risk. It points to the complex challenges of violence prevention, including the need for interventions among men and gender-transformative approaches to promote gender-equitable attitudes, practices and norms among men and women.

    Resistive forces along convergent plate boundaries have a major impact on surface deformation, most visibly at collisional plate boundaries. Although quantification of these forces is key to understanding the evolution and present state of mountain belts, they remain highly uncertain due to the complexity of plate boundary structures and rheologies. In this study we analyze the evolution of forces along the southern boundary of the Eurasian plate. Our approach to studying the collision is based on mechanical equilibrium of the whole Eurasian plate, meaning that an increase in collision forces must be matched by other plate tectonic forces. We first focus on present-day Eurasia. We include basal tractions from a global convection model, lithospheric body forces, and edge forces resulting from interaction of the Eurasian plate with neighboring plates. The resulting force distribution is best constrained for the present-day due to the availability of a large amount of stress observations. Eurasia's stress field turns out to be sensitive to the distribution of collision forces on the plate's southern margin and, to a lesser extent, to lithospheric density structure and normal pressure from mantle flow. Stress observations require collision forces on the India-Eurasia boundary of 7.2 - 10.5 TN/m. A similar analysis is performed for Eurasia at 20Ma and 40Ma.The geometry is taken from the global Lausanne (Stampfli) reconstruction, as are plate velocities and oceanic ages. Lithospheric body forces are accounted for in a simplified way because we lack detailed enough information on the plate scale topography. For the Miocene, we find ~1.2 TN/m for the collision force on the India-Eurasia boundary. In the Eocene, the collision force we find is ~0.4 TN/m. We conclude that the collision force increased significantly after 20Ma. From 40-20Ma, the plate contact force on the India/Tibet plate boundary segment was of the same order of magnitude as resistive forces on subduction

    India, the seventh largest country in the world, has diverse geographical and climatic regions with vast rural and peri-urban areas. Many are experiencing an escalation in the spread and intensity of numerous human diseases transmitted by insects. Classically, the management of these vector-borne diseases is underpinned by either chemical insecticides and/or environmental management targeted at the vector. However, these methods or their present implementation do not offer acceptable levels of control, and more effective and sustainable options are now available. Genetic strategies for the prevention of arbovirus transmission are most advanced for dengue and chikungunya, targeting their primary vector, Aedes aegypti. The national burden in terms of morbidity and mortality as a direct consequence of dengue virus in India is considered to be the largest worldwide, over 4 times that of any other country. Presently, new genetic technologies are undergoing field evaluation of their biosafety and efficacy in several countries. This paper discusses the merits of these approaches and argues for fair and transparent appraisal in India as a matter of urgency. Identification of any associated risks and their appropriate mitigation are fundamental to that process.

    The study of islands as model systems has played an important role in the development of evolutionary and ecological theory. The 50th anniversary of MacArthur and Wilson's (December 1963) article, 'An equilibrium theory of insular zoogeography', was a recent milestone for this theme. Since 1963, island systems have provided new insights into the formation of ecological communities. Here, building on such developments, we highlight prospects for research on islands to improve our understanding of the ecology and evolution of communities in general. Throughout, we emphasise how attributes of islands combine to provide unusual research opportunities, the implications of which stretch far beyond islands. Molecular tools and increasing data acquisition now permit re-assessment of some fundamental issues that interested MacArthur and Wilson. These include the formation of ecological networks, species abundance distributions, and the contribution of evolution to community assembly. We also extend our prospects to other fields of ecology and evolution - understanding ecosystem functioning, speciation and diversification - frequently employing assets of oceanic islands in inferring the geographic area within which evolution has occurred, and potential barriers to gene flow. Although island-based theory is continually being enriched, incorporating non-equilibrium dynamics is identified as a major challenge for the future.

    Forests are the chief resource for the collection and exploration of biological materials. The past few decades have witnessed a large scale deforestation in India due to substantial pressures generated by population growth, leading to demand for more land for agriculture, urbanization and industrial activities, in addition to increased demand for fuel wood and timber. This has resulted in the loss of soil cover, habitat destruction, environmental degradation and ecological imbalance. This scenario has created a progressive awareness for the conservation and restoration of habitats and, thus, the declaration of many forest areas into protected zones, such as national parks, biosphere reserves, etc., including the protection of some marine areas, by both the National and State Governments. Normally, permission for biological collecting is not granted in these protected areas. In India, forests are a State subject and grant for collection permission is vested with the State Forest Departments. In the absence of any rules, regulations and guidelines, either from National or State Governments, forest authorities impose their terms and conditions, which are arbitrary and even contradictory at times, in the process of granting collecting permits. A set of new rules to be applied throughout the country is needed.

    Myasthenia gravis (MG) requires lifelong treatment. The cost of management MG is very high in developed countries but there is no information on the cost of management of MG in the developing countries. This study reports the direct and indirect cost and predictors of cost of MG in a tertiary care teaching hospital in India. In a prospective hospital based study, from a tertiary hospital in India 66 consecutive patient during 2014-2015 were included. The age of the patients ranged between 6 and 75years. The severity of MG was assessed by myasthenia gravis foundation association (MGFA) class (MGFA) I-V. The patient data was collected s and their direct cost was calculated from the computerized Hospital information system. The indirect cost was calculated from patient's memory, checking the bills of transportation and wages loss by the patient or the care giver. Total annual cost of MG ranged between INR (4560-532227) with median INR 61390.5 (US$911.64). The median cost of outpatient department (OPD) consultation of 16 patients was INR 20439.9 (US$303.53), of 50 admitted patients was INR 44311.8 (US$658.03) and 21 intensive care unit (ICU) patients was INR 59574.3 (US$ 884.6) and the direct cost of thymectomy was INR 45000 (US$ 668.25). Direct cost was related to indirect cost (r=0.55; p=0.0001). Predictors of patient outcome were severity of MG, ICU admission, and thymectomy. The total median cost for management of myasthenia gravis was INR 61390.5 (4560-532227, US$911.64) per year, and the cost was mainly determined by the severity of MG.

    Felsic magmatism associated with ocean-ocean and ocean-continent subduction processes provide important evidence for distinct episodes of crust-generation and continental lithospheric evolution. Rhyolites constitute an integral component of the tholeiitic to calc-alkaline basalt-andesite-dacite-rhyolite (BADR) association and contribute to crustal growth processes at convergent plate margins. The evolution of the Dharwar Craton of southern peninsular India during Meso- to Neoarchean times was marked by extensive development of greenstone belts. These granite-greenstone terranes have distinct volcano-sedimentary associations consistent with their geodynamic setting. The present study deals with geochemistry of rhyolites from the Chitradurga-Shimoga greenstone belts of western (WDC) and the Gadwal-Kadiri greenstone belts of eastern (EDC) sectors of Dharwar Craton to compare and evaluate their petrogenesis and geodynamic setting and their control on the continental lithospheric evolution of the Dharwar Craton. At a similar range of SiO2, Al2O3, Fe2O3, the rhyolites of WDC are more potassic, whereas the EDC rhyolites are more sodic and less magnesian with slight increase in TiO2. Minor increase in MgO content of WDC rhyolites reflects their ferromagnesian trace elements which are comparatively lower in the rhyolites of EDC. The relative enrichment in LILE (K, Rb) and depletion in HFSE (Nb, Ta, Zr, Hf) marked by negative Nb-Ta, Zr-Hf and Ti anomalies endorse the convergent margin processes for the generation of rhyolites of both the sectors of Dharwar Craton. The high silica potassic rhyolites of Shimoga and Chitradurga greenstone belts of WDC showing prominent negative Eu and Ti anomalies, flat HREE patterns correspond to Type 3 rhyolites and clearly point towards their generation and emplacement in an active continental margin environment. The geochemical characteristics of Gadwal and Kadiri rhyolites from eastern Dharwar Craton marked by aluminous compositions with

    The present study on geochemical evolution of groundwater is taken up to assess the controlling processes of water chemistry in the Western Delta region of the River Godavari (Andhra Pradesh), which is one of the major rice-producing centers in India. The study region is underlain by coarse sand with black clay (buried channels), black silty clay of recent origin (floodplain) and gray/white fine sand of modern beach sediment of marine source (coastal zone), including brown silty clay with fine sand (paleo-beach ridges). Groundwater is mostly brackish and very hard. It is characterized by Na+ > Mg2+ > Ca2+:HCO3 - > Cl- > SO4 2- > NO3 -, Na+ > Mg2+ > Ca2+:Cl- > HCO3 - > SO4 2-, and Mg2+ > Na+ > Ca2+ > or < K+:HCO3 - > Cl- > or > SO4 2- facies. The ionic relations (Ca2+ + Mg2+:HCO3 -, Ca2+ + Mg2+:SO4 2- + HCO3 -, Na+ + K+:TC, Na+ + K+:Cl- + SO4 2-, HCO3 -:TC, HCO3 -:Ca2+ + Mg2+, Na+:Cl- and Na+:Ca2+) indicate that the rock weathering, mineral dissolution, evaporation and ion exchange are the processes to control the aquifer chemistry. Anthropogenic and marine sources are also the supplementary factors for brackish water quality. These observations are further supported by Gibbs mechanisms that control the water chemistry. Thus, the study suggests that the initial quality of groundwater of geogenic origin has been subsequently modified by the influences of anthropogenic and marine sources.

    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.

    Two-wheeler vehicles in Delhi, India--roughly 70% of the total vehicle fleet--are responsible for a significant portion of the city's vehicle emissions and petroleum consumption. An inspection and maintenance (I/M) program that ensures vehicle emission control systems are well maintained can complement other emission reduction strategies. This paper presents the initial findings of extensive data collected on vehicle characteristics and emissions for two-wheeler vehicles operating in Delhi in a series of I/M camps conducted by the Society of Indian Automobile Manufacturers and various partners in late 1999. The analysis shows idle HC and CO emissions [measured in terms of parts per million (ppm) and volume % (vol %), respectively] in a slow declining trend with subsequent model years, reflecting tighter emission standards and more advanced emission technologies. The I/M benefits--3 vol % and 39% reduction in idle and mass CO, respectively; 40 vol % and 22% reduction in idle and mass HC, respectively; and a 10-20% increase in fuel efficiency--were higher than those reported in the literature. Although these benefits are substantial, any implementation strategy needs to consider cost-effectiveness. In the present study, only 10% of vehicles--contributing 22% of the total vehicle emissions--failed the idle CO standard. Fleet emissions data variability necessitates a large sample size to develop a baseline for the vehicle fleet, but a smaller, scientifically designed sample and better data collection quality could periodically track the benefits at future camps.

Out of 37 unifloral samples found 25 were contributed by Apis cerana indica, seven by A. dorsata and the remaining five by A. florea. Out of 14 multifloral samples five were contributed by A. cerana indica, five by A. dorsata and the remaining four by A. florea. Principal component analysis confirmed the palynological classification of the unifloral honey samples. Eighty-two bee-plant taxa belonging to forty four families were recovered. The predominant nectariferous taxa of the spring season were Acanthus ilicifolius, Avicennia marina, Bruguiera gymnorrhiza, Cocos nucifera, Eucalyptus globulus, Phoenix paludosa, Pongamia pinnata, Prosopis juliflora, Sonneratia apetala and Syzygium cumini. In the summer the predominant nectariferous taxa were Borassus flabellifer, C. nucifera, E. globulus, Syzygium cumini, Terminalia arjuna, Aegiceras corniculatum, P. paludosa and Sonneratia apetala while those of the winter were Brassica nigra, Coriandrum sativum, Zizyphus jujuba, Alstonia scholaris, E. globulus and Bruguiera gymnorrhiza. Very low (<0.09) HDE/P for 98% of the samples and absence of toxic palynotaxa assure that these honeys are suitable for human consumption. Quite extended honey flow period with spring and summer as best forage seasons for the honeybees and occurrence of 82% of these honeys with APC Group II, III and IV justify the sustainability of the present study area for establishing moderate to large-scale apicultural entrepreneurship. This should improve the socio-economic status of the people of this region. PMID:24740144

    The purpose of this study was to describe the evolution of pedagogical content knowledge in prospective secondary chemistry and physics teachers. A new paradigmatic framework was developed to guide the research. Craft knowledge and pedagogical content knowledge were compared and combined forming a new perspective from which to view secondary chemistry and physics teachers' "learning to teach." A second purpose of this study was to develop philosophically-derived, domain-specific, pedagogical content knowledge taxonomies. Four taxonomies were developed in all; two general and two domain-specific. The general taxonomies describe types of pedagogical content knowledge and attributes of pedagogical content knowledge. The two domain-specific taxonomies describe topics common to both physics and chemistry and outline domain-specific laboratories for the differentiation between heat and temperature. A methodological theoretical framework, synthesized from radical and social constructivism, was developed to guide the researcher in data collection, analysis, and interpretation. The researcher used four cases, two prospective chemistry teachers and two prospective physics teachers, and followed their development through the science curriculum class and student teaching field experience of their teacher preparation program. Content-specific, situational vignettes were created as a tool to monitor the participants' development of pedagogical content knowledge. The vignettes were administered using a modified microgenetic method. The modified microgenetic procedure involved the repeated administration of a task (vignette) over a period of time to monitor cognitive change. Data were collected through several methods: participant responses to the vignettes, field notes taken during the science curriculum class and student teaching field experience, interviews, artifact collection, and journals. Data were analyzed using qualitative content analysis. The results of this study

    Carbonate rocks undergo karstic process and karst morphology is a key to understand the nature and genesis of caves. The primary energy source for the formation of karst landforms is hydrological cycle. Geomorphic features along with hydrological characteristics provide important information not only on karst formation but also climate and environmental conditions. In this paper, we present the tectonic and geomorphic features that played a role in evolution of caves located in Chhattisgarh and Orissa States of India. The geomorphic and tectonic aspects of Kotumsar, Kailash, and Gupteshwar caves are discussed in relation to the origin and evolution of these caves. Caves are located near the water falls. The area is folded and faulted along the Eastern Ghat Mobile Belt (EGMB) due to tectonic reactivation. Shaly-limestone beds exhibit vertical dipping near Gupteshwar cave, and steeply inclined near Kotumsar and Kailash caves. Indrāvati and Sabari/Kolab tributaries of the Godavari River drain the area. The landscape evolution and the origin of caves in the region is a multistage process, where the lithology, orogeny, fluvial action, and monsoon are the main agents, which is similar to the four state model (Ford and Ewers, 1978). The river basin evolution and regional tectonism also caused the initiation of karstification in the region. The evolution of caves is believed to have taken place in Pre-Pliocene under more humid conditions that coincided with the initiation of monsoon in India. Further, during the Quaternary wet-dry/cold-warm phases altered physical and chemical weathering of limestone rocks. Contrasting relief features of Bastar plateau have also helped the extensive cave formation in the region. The dissolution along weak planes initiated the openings of caves, further enlarged by geomorphic agents. Both monsoon and tectonics have caused fluctuations in water levels along river courses, which acted as active agents in evolution of caves.

    Mucormycosis is an emerging angioinvasive infection caused by the ubiquitous filamentous fungi of the Order Mucorales and class of Mucormycetes. We conducted a prospective study of 38 patients who were diagnosed as having mucormycosis in a tertiary care hospital during January 2010 to June 2011. The cases were analyzed regarding the site of involvement, underlying disease and species of fungi isolated, antifungal susceptibility pattern of the isolates, and outcome of therapy. The mean age of the patients was 40.43 years, with 72% male. Rhino-orbital mucormycosis (61.5%) was the most common presentation followed by cutaneous manifestations (31%), gastrointestinal symptoms (5%), and pulmonary (2.5%). Diabetes mellitus (56%) was the significant risk factor in rhino-orbito-cerebral presentation (OR = 7.55, P = 0.001). Among 23 culture isolates, Rhizopus arrhizus (37.5%) was the most common, followed by Apophysomyces variabilis (29.2%), Lichtheimia ramosa (16.7%), Rhizopus microsporus (4.2%), Rhizomucor pusillus (4.2%), and Apophysomyces elegans (4.2%). Rhizopus arrhizus was most commonly isolated from rhino-orbito-cerebral mucormycosis and Apophysomyces species were generally obtained from cutaneous mucormycosis. In vitro antifungal susceptibility showed that 16 isolates were sensitive to amphotericin B (MIC less than 1 μg/ml), while in contrast, all isolates were found to be resistant to voriconazole (MIC- 0.25 to >8), fluconazole (MIC > 32), flucytosine (MIC > 32). Treatment regimens included antifungal therapy, reversal of underlying predisposing risk factors, and surgical debridement. Combination of surgery and medical treatment with amphotericin B was significantly better (OR = 0.2, P < 0.04) than amphotericin B alone (61.5% vs. 10.3% patient survival). The awareness of fungal diseases amongst clinicians is required to decrease the fatal outcome of disease.

    A deep low in sea-level pressure is present from May to September over Pakistan and northwestern India (hereafter, the Pak-India low). It is often referred as the "heat" low to convey the significance of surface thermal effects reckoned to be important for its origin. The present analysis, rooted in observations and diagnostic modeling, suggests that the Pak-India low is influenced both by regional and remote forcing. Regionally, the influence of Hindu Kush mountains is found to be stronger than the impact of land-surface heating and attendant sensible heating of the planetary boundary layer, questioning the suitability of the "heat" label in canonical references to this circulation feature. Observational analysis indicates that the notable May-to-June deepening of the Pak-India low and its further deepening in July, however, arises from remote forcing—the development of monsoon deep-convection over the Bay of Bengal and eastern India in June and July. It is hypothesized that the associated upstream descent over Iran-Turkmenistan-Afghanistan (i.e. east of the Caspian Sea) and related low-level northerlies over the Elburz-Zagros-Hindu Kush mountains contribute to the strengthening of the Pak-India low in June (and July) from interaction with regional orography.

    The Bengal basin, the largest fluvio-deltaic sedimentary system on Earth, is located in Bangladesh and three eastern states of India. Sediment accumulates in the basin from the Ganges, Brahmaputra, and Meghna (GBM) river systems and is dispersed into the Bay of Bengal, forming the largest submarine fan in the world. The basin is located in the Himalayan foreland at the junction of the Indian, Eurasian, and Burmese plates. The basin is bounded by the Indian craton on the west and the Indo-Burmese fold belts on the east. It can be broadly divided into a stable shelf and a foredeep separated by a deep seismic hinge zone. Basin sediments overlie Gondwanan basement and vary in thickness from a few kilometers on the stable shelf to more than 16 km in the foredeep. The basin was initiated at the breakup of Gondwanaland in the late Mesozoic and evolved through the formation of the proto-GBM delta to the present delta starting around 10.5 Ma. The stratigraphy of the different parts of the basin differs considerably, because of contrast in depositional history within the several sub-basins that were produced by intra-plate tectonic activities associated with ongoing Himalayan orogeny. The present-day geomorphology is dominated by the extensive Holocene GBM floodplain and delta. The vertical succession of the deltaic plain can be classified into five units on the basis of differences in grain size, which reflect differing depositional environments. The initiation of the modern GBM delta at the onset of the Pleistocene glacial maximum and its evolution to the present configuration are intricately related to Holocene fluvio-dynamic processes, eustatic sea-level changes, and tectonic movements. The sedimentology and mineralogy of the different parts of the basin reflect differences in sediment provenance. The mineralogy is dominated by detrital quartz, some feldspar, and minor amounts of carbonates; illite and kaolinite are the main clay minerals. The basin has profuse

    Background In low/middle income countries like India, diabetes is prevalent and health care access limited. Most adults have a mobile phone, creating potential for mHealth interventions to improve public health. To examine the feasibility and initial evidence of effectiveness of mDiabetes, a text messaging program to improve diabetes risk behaviors, a global nonprofit organization (Arogya World) implemented mDiabetes among one million Indian adults. Objective A prospective, parallel cohort design was applied to examine whether mDiabetes improved fruit, vegetable, and fat intakes and exercise. Methods Intervention participants were randomly selected from the one million Nokia subscribers who elected to opt in to mDiabetes. Control group participants were randomly selected from non-Nokia mobile phone subscribers. mDiabetes participants received 56 text messages in their choice of 12 languages over 6 months; control participants received no contact. Messages were designed to motivate improvement in diabetes risk behaviors and increase awareness about the causes and complications of diabetes. Participant health behaviors (exercise and fruit, vegetable, and fat intake) were assessed between 2012 and 2013 via telephone surveys by blinded assessors at baseline and 6 months later. Data were cleaned and analyzed in 2014 and 2015. Results 982 participants in the intervention group and 943 in the control group consented to take the phone survey at baselne. At the end of the 6-month period, 611 (62.22%) in the intervention and 632 (67.02%) in the control group completed the follow-up telephone survey.

    Background The importance of maternal sanitation behaviour during pregnancy for birth outcomes remains unclear. Poor sanitation practices can promote infection and induce stress during pregnancy and may contribute to adverse pregnancy outcomes (APOs). We aimed to assess whether poor sanitation practices were associated with increased risk of APOs such as preterm birth and low birth weight in a population-based study in rural India. Methods and Findings A prospective cohort of pregnant women (n = 670) in their first trimester of pregnancy was enrolled and followed until birth. Socio-demographic, clinical, and anthropometric factors, along with access to toilets and sanitation practices, were recorded at enrolment (12th week of gestation). A trained community health volunteer conducted home visits to ensure retention in the study and learn about study outcomes during the course of pregnancy. Unadjusted odds ratios (ORs) and adjusted odds ratios (AORs) and 95% confidence intervals for APOs were estimated by logistic regression models. Of the 667 women who were retained at the end of the study, 58.2% practiced open defecation and 25.7% experienced APOs, including 130 (19.4%) preterm births, 95 (14.2%) births with low birth weight, 11 (1.7%) spontaneous abortions, and six (0.9%) stillbirths. Unadjusted ORs for APOs (OR: 2.53; 95% CI: 1.72–3.71), preterm birth (OR: 2.36; 95% CI: 1.54–3.62), and low birth weight (OR: 2.00; 95% CI: 1.24–3.23) were found to be significantly associated with open defecation practices. After adjustment for potential confounders such as maternal socio-demographic and clinical factors, open defecation was still significantly associated with increased odds of APOs (AOR: 2.38; 95% CI: 1.49–3.80) and preterm birth (AOR: 2.22; 95% CI: 1.29–3.79) but not low birth weight (AOR: 1.61; 95% CI: 0.94–2.73). The association between APOs and open defecation was independent of poverty and caste. Even though we accounted for several key

    Cultural factors have a significant impact on the manifestation of psychiatric illness and the development of the ego ideal. The evolution of the widow's cultural role in a South India village provides insight on the ego ideal through several generations. As treatment of widows changed so that their appearance became indistinguishable from other women, they no longer became objects of revulsion. A case study approach documents the interrelationship of changes in the cultural ego ideal on psychiatric illness among widows in a South India village over a period of more than four decades.

    Despite successful implementation of directly observed treatment, short course (DOTS) in India, the growing number of diabetes mellitus (DM) patients appears to be a cause in the increasing tuberculosis (TB) incidence, affecting their management. In this regard, a prospective study was conducted on DOTS patients in three primary health care centers in urban slum region of South Delhi, India, to evaluate the effect of DM on sputum conversion, treatment outcome, and adverse drug reactions (ADR) due to anti-TB treatment. Eligible TB patients underwent blood glucose screening at treatment initiation. Disease presentation, clinical outcome, and ADRs were compared between patients of TB with and without DM. Out of 316 patients, the prevalence of DM was found to be 15.8%, in which 19.4% and 9.6% were PTB and EPTB patients, respectively. DM patients have observed higher sputum positivity (OR 1.247 95% CI; 0.539–2.886) at the end of 2-month treatment and poor outcome (OR 1.176 95% CI; 0.310–4.457) at the completion of treatment compared with non DM patients. Presence of DM was significantly associated (OR 3.578 95% CI; 1.114–11.494, p = 0.032) with the development of ADRs. DM influences the treatment outcome of PTB patients in our setting and also on the ADR incidence. PMID:27642601

The accreted tectonic elements include suprasubduction complexes of arc magmatic sequences, high-grade supracrustals, thrust duplexes, ophiolites, and younger intrusions that are dispersed along the suture. The intra-oceanic Neoarchean-Neoproterozoic arc assemblages are well exposed in the form of tectonic mélanges dominantly towards the eastern sector of the CSZ and are typically subjected to complex and multiple deformation events. Multi-scale analysis of structural elements with detailed geological mapping of the sub-regions and their structural cross sections, geochemical and geochronological data and integrated geophysical observations suggest that the CSZ is an important zone that preserves the imprints of multiple cycles of Precambrian plate tectonic regimes.

    An accurate prediction of extreme rainfall events can significantly aid in policy making and also in designing an effective risk management system. Frequent occurrences of droughts and floods in the past have severely affected the Indian economy, which depends primarily on agriculture. Data mining is a powerful new technology which helps in extracting hidden predictive information (future trends and behaviors) from large databases and thus allowing decision makers to make proactive knowledge-driven decisions. In this study, a data-mining algorithm making use of the concepts of minimal occurrences with constraints and time lags is used to discover association rules between extreme rainfall events and climatic indices. The algorithm considers only the extreme events as the target episodes (consequents) by separating these from the normal episodes, which are quite frequent, and finds the time-lagged relationships with the climatic indices, which are treated as the antecedents. Association rules are generated for all the five homogenous regions of India and also for All India by making use of the data from 1960 to 1982. The analysis of the rules shows that strong relationships exist between the climatic indices chosen, i.e., Darwin sea level pressure, North Atlantic Oscillation, Nino 3.4 and sea surface temperature values, and the extreme rainfall events. Validation of the rules using data for the period 1983-2005 clearly shows that most of the rules are repeating, and for some rules, even if they are not exactly the same, the combinations of the indices mentioned in these rules are the same during validation period, with slight variations in the classes taken by the indices.

  12. Kinematic evolution, metamorphism, and exhumation of the Greater Himalayan Series, Sutlej River and Zanskar regions of NW India

    NASA Astrophysics Data System (ADS)

    Stahr, Donald William, III

    The Himalayan orogen provides a natural laboratory to test models of orogenic development due to large-scale continental collision. The Greater Himalayan Series (GHS), a lithotectonic unit continuous along the entire length of the belt, comprises the metamorphic core of the Himalayan orogen and underlies the highest topography. GHS rocks are exposed as a moderately northdipping slab bounded below by the Main Central Thrust (MCT) and above by the South Tibetan Detachment System (STDS) of normal faults. Coeval reverse- and normal-sense motion on the crustal-scale MCT and STDS ductile shear zones allows the GHS to be modeled as an extruded wedge or channel of mid-crustal material. Due to this unique tectonic setting, the deformation path of rocks within the bounding shear zones and throughout the core of the GHS profoundly influences the efficiency of extrusion and exhumation processes. Attempts to quantify GHS deformation and metamorphic evolution have provided significant insight into Himalayan orogenic development, but these structural and petrologic studies are often conducted in isolation. Penetrative deformation fabrics developed under mid-upper amphibolite facies conditions within the GHS argue that deformation and metamorphism were coupled, and this should be considered in studies aimed at quantifying GHS teconometamorphic evolution. This work focuses on two projects related to the coupled deformation, thermal and metamorphic evolution during extrusion and exhumation of the GHS, focused on the lower and upper margins of the slab. A detailed examination of the P--T history of a schist collected from within the MCT zone of the Sutlej River, NW India, provides insight into the path experienced by these rocks as they traveled through the crust in response to the extreme shortening related to India-Asia collision. Combined forward thermodynamic and diffusion modeling indicates compositional zoning preserved in garnet has remained unmodified since growth and can be

    The Hutti-Maski Greenstone Belt (HMGB), situated in the eastern block of the Dharwar Craton, India is dominated by bimodal volcanics with a minimum magmatic age of 2586 ± 59 Ma. Two phases of granitoid intruded into the belt, the syn-tectonic Kavital granitoid, homogeneous, medium-grained porphyritic granodiorite, with an intrusion age of 2543 ± 9 Ma, followed by the post-tectonic Yelagatti granitoid, heterogeneous, fine- to medium-grained granite to granodiorite. The extensively altered zircons from the Yelagatti granitoid have significant enrichments of U, Th (>1%) and common-Pb (up to 47%). Only two of the analyses were reproducible, providing a minimum 207Pb/ 206Pb age of 2221 ± 99 Ma, this may indicate an approximate magmatic age or more realistically a subsequent event. Felsic metavolcanic rocks contain cross-cutting veinlets, which formed during the Mesoproterozoic (ca. 1180 Ma), the final closure of the Pb system occurred between the Neoproterozoic and Ordovician, possibly related to the Pan-African orogeny. The tectono-magmatic evolution of the HMGB can be correlated with the collision between the eastern and western blocks of the Dharwar Craton subsequent to 2658 Ma and the craton wide magmatism from 2613 to 2513 Ma. These events can be accounted for by combining uniformitarian and non-uniformitarian models.

    The eastern Karakoram terrane, NW India, records crustal evolution in the core of the Himalayan-Tibetan orogen. Recent debate has centred on whether prograde metamorphism, anatexis and leucogranite emplacement were the result of localised shear heating and magma advection within the Karakoram Fault Zone (KFZ) or instead predate the KFZ and were the result of regional tectonometamophic events. Inclusions within andalusite porphyroblasts that grew during 15.7 Ma leucogranite emplacement have fabrics that are random or discordant to the KFZ matrix foliation, indicating that the KFZ initiated after this time. Therefore, earlier anatexis and metamorphism are the result of regional metamorphic events. Amphibole-plagioclase thermobarometry on a c. 17 Ma migmatite melanosome, later exhumed within a transpressional zone of the KFZ, shows that melting occurred at 688 °C and 522 MPa. Amphibolites record an older kyanite-grade metamorphic event that occurred at 677-736 °C and 875-1059 MPa. Metapelites also record a kyanite-grade event which is constrained by Ti-in-biotite thermometry to have occurred at 622 °C and > 650 MPa. The tectonometamorphic history of the eastern Karakoram correlates closely with that of the central Karakoram away from the KFZ. This correlation supports the interpretation that metamorphism and anatexis were regional in extent and also indicates a limited offset of < 150 km on the KFZ.

    The recent evolution of extreme high waters along the severe cyclone-risk coasts of the Bay of Bengal (the east coast of India and Bangladesh) was assessed using long-term (24-34 years) hourly tide gauge data available from five stations. The highest water levels above mean sea level have the greatest magnitude towards the northern part of the Bay, which decreases towards its south-west. Extreme high waters were observed to result from a combination of moderate, or even small, surges with large tides at these stations in most of the cases. Increasing trends, which are significant, were observed in the extreme high waters at Hiron Point, at the head of the Bay. However, the trends in extremes are slightly lower than its mean sea level trend. For the other stations, Cox's Bazaar, Paradip Visakhapatnam and Chennai, no significant trends were observed. At inter-annual time scales, changes in extreme high waters in the Bay of Bengal were found to be influenced by the El Niño Southern Oscillation and the Indian Ocean Dipole.

    One of the most challenging problems in understanding the tectonics of active mountain belts is the presence of normal faults in the overall compressive settings. Consistent observations in the Andes, the Alps, as well as in the Himalaya record the presence of upper crustal structures with normal displacement contemporaneously with shortening and thrusting at lower crustal levels and elevations. Within the internal and high elevation sectors of the Himalayan orogen, active N-S striking normal fault systems are well documented. Crosscutting relationships indicate that these closely spaced faults cut all pre-existing compressional structures and are the youngest structural features in this region. However, their mode of propagation in time and space, as well as their origin remain largely unknown. For example, in the Sutlej River region (NW Himalaya, India), it is unclear whether these fault systems either are a local phenomenon and related to ongoing exhumation of the Leo Pargil metamorphic dome or, alternatively, are an integral part of the structural framework in the Himalaya and thus of regional importance. To better understand which processes constrain N-S striking normal faulting in the evolution of the Higher Himalaya, we have mapped the young extensional sectors in the greater Sutlej River area. In addition, we combine seismological data with the spacial and temporal distribution of brittle normal faulting to better understand the interaction between the ongoing normal and thrust faulting in the orogen. Using globally recorded seismicity data we observed ongoing extension in a N-S striking band extending from to the Leo Pargil extensional dome southward to the main thrust belts along the Himalayan front. Further installation of a seismic network in this region will provide the level of resolution needed to analyze the detailed pattern of local seismicity of the Sutlej-Spiti River region. Our preliminary structural geological field work reveals that the

    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.

    As the incidence of end-stage renal disease (ESRD) is rapidly increasing, the demand for dialysis and transplantation has dramatically increased, which has led to concerns about the availability and equitable allocation of kidneys for transplantation. The distribution of HLA-A, B and DR alleles in 148 renal transplant recipients and 191 live related prospective donors from 2009 to 2010 were analyzed. Allele frequencies and haplotype frequencies were calculated in recipients and donors. The prospective donors were further analyzed on the basis of their relationship to the patients and according to the sex ratio. A significant female preponderance was noted in the prospective donor population, most of whom were either siblings or parents of the recipients. On the contrary, the recipient population predominantly comprised of males. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in renal transplant patients were HLA-AFNx0111, AFNx0102, AFNx0101, AFNx0124; HLA-BFNx0135, BFNx0140, BFNx0144, BFNx0115, BFNx0152, and HLA-DRB1FNx0115, DRB1FNx0107, DRB1FNx0113, DRB1FNx0111 respectively. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in prospective donors were HLA-AFNx0102, AFNx0111, AFNx0133, AFNx0124; HLA-BFNx0135, BFNx0144, BFNx0140, BFNx0115 and HLA-DRB1FNx0115, DRB1FNx0107, DRB1FNx0111, DRB1FNx0113 respectively. AFNx0111-BFNx0135, AFNx0102-DRB1FNx0115, BFNx0140-DRB1FNx0115 were the most common HLA A-B , HLA A-DR, HLA B-DR haplotypes respectively in renal transplant patients, whereas, AFNx0111-BFNx0135, AFNx0111-DRB1FNx0115, BFNx0144-DRB1FNx0107 were the most common haplotypes in renal donors. In three locus haplotype, HLA-AFNx0102-BFNx0140-DRB1FNx0115 was the most frequent haplotype in patients, whereas, in prospective renal donors HLA-AFNx0133-BFNx0144-DRB1FNx0107 was the most frequent haplotype.

    In this study, we integrate environmental magnetic, sedimentological, and geochemical records of sediment core of Hole NGHP-01-10D overlying methane hydrate deposits to decipher the controls on the evolution of fracture-filled gas-hydrate system in the Krishna-Godavari (K-G) basin. Four distinct sedimentary units have been identified, based on the sediment magnetic signatures. An anomalous zone of enhanced magnetic susceptibility (Unit III: 51.9-160.4 mbsf) coinciding with the gas hydrate bearing intervals is due to the presence of magnetite-rich detrital minerals brought-in by the river systems as a result of higher sedimentation events in K-G basin and has no influence over hydrate formation. A strong to moderate correlation between magnetite concentration and chromium reducible sulfur (CRS) content indicates significant influence of sulfidization on the magnetic record and could be further exploited as a proxy to decipher paleo-H2S seepage events. Analysis of high-resolution seismic, bathymetry, and sub-bottom profiler data reveals the existence of a regional fault system in K-G basin. The opening and closing dynamics of the faults facilitated the migration and trapping of required gas concentrations resulting in accumulation of gas hydrates at the studied site. The seismic data provides support to the rock-magnetic interpretations. The observed variations in magnetic and geochemical properties have resulted from the episodic flow of methane and sulfide-enriched fluids through the fracture-filled network formed as a result of shale-tectonism. Our study demonstrated the potential of using an enviro-magnetic approach in combination with other proxies to constrain the evolution of gas-hydrate system in marine environments.

    Background: The Body Tambura is a recently invented stringed instrument that is used for receptive music therapy designed to be placed and attached on the human body. The aim of this study was to record perceived effects of a treatment with the Body Tambura on palliative care patients with special reference to pain. Materials and Methods: A prospective case study was carried out with patients of St. Joseph's Hospice for Dying Destitute in Dindigul/South India. Patients were treated with a treatment after baseline assessment and also on the next day. Outcomes were measured quantitatively by using a numeric rating scale (0–10, 10 maximum intensity of pain felt) at baseline, directly after treatment, and the day after the treatment to determine the intensity of the pain. Results: Ten patients (five women and five men) participated in the study. The majority described the therapy as a pleasant experience. The pain intensity at baseline was reduced from 8.3 ± standard deviation (SD) 1.16 to 4.6 ± 1.52 at day 1 and from 4.6 ± 2.07 to 2.4 ± 1.58 at day 2. Conclusion: A clinically relevant pain reduction was described as short time outcome; the therapy was received and perceived well. Forthcoming research should include a control group, randomization, a larger number of participants, and a longer period of treatment. PMID:26009680

    2016-01-01

    Objective. The study was conducted to assess the treatment outcome of different category retreatment cases with the aim of finding out the important predictors of unfavorable outcomes. Methodology. This hospital based prospective cohort study was conducted in three tuberculosis units (TUs) of west Midnapore (a district of Eastern India), covering mostly the tribal populated areas. Patients who were registered for Category II antituberculosis treatment between 1st quarter of 2013 (Jan to Mar) and 4th quarter of 2013 (Oct to Dec) were considered as our study cohort and they were followed up till December 2014. The study was started with 177 patients but ultimately ended with 165 patients. Results. Unfavorable outcome was observed among 24.8% patients. Among them mostly 51.2% were defaulter, 22% were failure case, and 26.8% died during treatment. Patients, who were minority by religion, were found 4 times more vulnerable for unfavorable outcome. Unfavorable outcome was found 7 times more common among retreatment TB cases who remain sputum positive after completion of initiation phase of Category II treatment. Conclusion. Programmatic approach should be specified to address the minority by religion population and to reduce the load of sputum positive cases after completion of initiation phase treatment by tracking them.

    Introduction: The phantom limb pain (PLP) and phantom limb sensation (PLS) are very common among amputated cancer patients, and they lead to considerable morbidity. In spite of this, there is a lack of epidemiological data of this phenomenon among the Asian population. This study was done to provide the data from Indian population. Methods: The prevalence of PLP, stump pain (SP), and PLS was prospectively analyzed from the amputated cancer patients over a period of 2 years in Dr. B.R.A. Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi. The risk factors and the impact of phantom phenomenon on patients were also noted. Results: The prevalence of PLP was 41% at 3 and 12 months and 45.3% at 6 months, whereas that of SP and PLS was 14.4% and 71.2% at 3 months, 18.75% and 37.1% at 6 months, 15.8% and 32.4% at 12 months, respectively. There was higher prevalence of PLP and PLS among the patients with history of preamputation pain, smoking with proximal level of amputation, receiving general anesthesia, receiving intravenous (IV) opioid postoperative analgesia, and developing neuroma or infection. Conclusion: The prevalence of PLP and PLS was higher among the cancer amputees as compared to SP, and a few risk factors responsible for their higher prevalence were found in our study. The PLP and PLS lead to considerable morbidity in terms of sleep disturbance and depression. PMID:28216859

    Karunakara, N.; Yashodhara, I.; Sudeep Kumara, K.; Tripathi, R. M.; Menon, S. N.; Kadam, S.; Chougaonkar, M. P.

    Indoor and outdoor gamma dose rates were evaluated around a prospective uranium mining region - Gogi, South India through (i) direct measurements using a GM based gamma dose survey meter, (ii) integrated measurement days using CaSO4:Dy based thermo luminescent dosimeters (TLDs), and (iii) analyses of 273 soil samples for 226Ra, 232Th, and 40K activity concentration using HPGe gamma spectrometry. The geometric mean values of indoor and outdoor gamma dose rates were 104 nGy h-1 and 97 nGy h-1, respectively with an indoor to outdoor dose ratio of 1.09. The gamma dose rates and activity concentrations of 226Ra, 232Th, and 40K varied significantly within a small area due to the highly localized mineralization of the elements. Correlation study showed that the dose estimated from the soil radioactivity is better correlated with that measured directly using the portable survey meter, when compared to that obtained from TLDs. This study showed that in a region having localized mineralization in situ measurements using dose survey meter provide better representative values of gamma dose rates.

    2015-01-01

    Background The Global Network for Women’s and Children’s Health Research is one of the largest international networks for testing and generating evidence-based recommendations for improvement of maternal-child health in resource-limited settings. Since 2009, Global Network sites in six low and middle-income countries have collected information on antenatal care practices, which are important as indicators of care and have implications for programs to improve maternal and child health. We sought to: (1) describe the quantity of antenatal care attendance over a four-year period; and (2) explore the quality of coverage for selected preventative, screening, and birth preparedness components. Methods The Maternal Newborn Health Registry (MNHR) is a prospective, population-based birth and pregnancy outcomes registry in Global Network sites, including: Argentina, Guatemala, India (Belgaum and Nagpur), Kenya, Pakistan, and Zambia. MNHR data from these sites were prospectively collected from January 1, 2010 – December 31, 2013 and analyzed for indicators related to quantity and patterns of ANC and coverage of key elements of recommended focused antenatal care. Descriptive statistics were generated overall by global region (Africa, Asia, and Latin America), and for each individual site. Results Overall, 96% of women reported at least one antenatal care visit. Indian sites demonstrated the highest percentage of women who initiated antenatal care during the first trimester. Women from the Latin American and Indian sites reported the highest number of at least 4 visits. Overall, 88% of women received tetanus toxoid. Only about half of all women reported having been screened for syphilis (49%) or anemia (50%). Rates of HIV testing were above 95% in the Argentina, African, and Indian sites. The Pakistan site demonstrated relatively high rates for birth preparation, but for most other preventative and screening interventions, posted lower coverage rates as compared to other

    The shear wave velocity of the crust along a ∼660 km profile from the west to the east coast of South India is mapped through the joint inversion of receiver functions and Rayleigh wave group velocity. The profile, consisting of 38 broadband seismic stations, covers the Archean Dharwar craton, Proterozoic Cuddapah basin, and rifted margin and escarpment. The Moho is mapped at a depth of ∼40 km beneath the mid-Archean Western Dharwar Craton (WDC), Cuddapah Basin (CB), and the west and east coasts formed through the rifting process. This is in contrast with a thin (∼35 km) crust beneath the late-Archean Eastern Dharwar Craton (EDC). Along the profile, the average thickness of the upper, middle and lower crust is ∼4 km, 12 ± 4 km and 24 ± 4 km respectively. Above the Moho, we observe a high-velocity layer (HVL, Vs > 4 km/s) of variable thickness increasing from 3 ± 1 km beneath the EDC to 11 ± 3 km beneath the WDC and the CB, and 18 ± 2 km beneath the west coast of India. The seismic wave velocity in this layer is greater than typical oceanic lower crust. We interpret the high-velocity layer as a signature of magmatic underplating due to past tectonic processes. Its significant thinning beneath the EDC may be attributed to crustal delamination or relamination at 2.5 Ga. These results demonstrate the dual signature of the Archean Dharwar crust. The change in the geochemical character of the crust possibly occurred at the end of Archean when Komatiite volcanism ceased. The unusually thick HVL beneath the west coast of India and the adjoining region may represent underplated material formed due to India-Madagascar rifting, which is supported by the presence of seaward dipping reflectors and a 85-90 Ma mafic dyke in the adjoining island.

    2015-01-01

    Over the past several years, an opinion has emerged in India that the current practical curricula in medical schools fail to meet many of the objectives for which they were instituted. Hence, this study has assessed the perception of physiology faculty members regarding the current experimental physiology curriculum in one Indian state, Gujarat. The faculty were of the opinion that many of the topics currently taught in experimental physiology (amphibian nerve-muscle and heart muscle experiments) were outdated and clinically irrelevant: Therefore, the faculty advocated that duration of teaching time devoted to some of these topics should be reduced and topics with clinical relevance should be introduced at the undergraduate level. The faculty also felt that more emphasis should be laid on highlighting the clinical aspect related to each concept taught in experimental physiology . Moreover, a majority of faculty members were in favour of replacing the current practice in Gujarat of teaching experimental physiology only by explanation of graphs obtained from experiments conducted in the previous years, with computer assisted learning in small groups.

    OBJECTIVE: To estimate the incidence and risk factors of group A streptococcus (GAS) sore throat among school-aged children living in a periurban slum area of Chandigarh, North India. METHODS: A total of 536 children aged 5-15 years from 261 families identified by a systematic random selection method were enrolled in the study. Episodes of sore throat were recorded through fortnightly home visits over a one-year period. The local vernacular (Hindi) terms gala kharab (bad throat) and khansi jukam (cough and cold) were used to identify symptoms of sore throat, and throat swab specimens were collected from children who had these symptoms on the day of the home visit. Bacterial culture was carried out and the isolation of GAS was confirmed using group-A-specific antiserum. FINDINGS: The incidences of sore throat and GAS sore throat were, respectively, 7.05 and 0.95 episodes per child-year. The incidence was higher in the following situations: among 11-year-olds, during the winter (November to January) and rainy (August) months (a bimodal peak), among children living in houses where there was no separate room for the kitchen, and in homes that included a tobacco smoker. CONCLUSION: The results show that the incidence of GAS sore throat was related to age, season, and indoor air pollution. PMID:11436474

    The western continental margin of India can be classed as a divergent or passive margin. The western continental shelf is an extensive carbonate bank (Bombay offshore basin) passing into clastic sediments on the north and south. Three craton-margin embayed basins-Kutch, Cambay, and Narmada- in the northern part of the shelf, are filled predominantly with clastic sediments. These basins occupy grabens bounded by faults diverging seaward. The grabens were formed by three rift systems along major Precambrian tectonic trends. The rifting developed sequentially from north to south around the Saurashtra horst. Kutch basin was formed in the Early Jurassic, followed by Cambay basin in Early Cretaceous time, and the Narmada in the Late Cretaceous. It appears that these rifting events occurred at successive stages during the northward migration of the Indian plate after its break from Gondwanaland in Late Triassic or Early Jurassic. It is inferred that these rift basins opened up successively as a result of the counterclockwise drift of the Indian craton. Bombay offshore and Cambay are two major oil-producing basins in the western margin. These basins are characterized by high geothermal gradients attributed to the shallowness of the mantle in this region. Oil has not been found in KUtch basin, which is mainly an onshore Mesozoic basin. The basin basin depocenter shifted offshore at the northwestern part of the continental shelf where the shelf is wide.

    Closure of Tethys marks initiation of collision between India and Asia, and the start of Himalayan orogenesis. A clear understanding of when this occurred is paramount to understanding the tectonic and denudational processes that have occurred since collision. A number of methods and datasets have been used to constrain the initiation of collision, from faunal mixing at 65 Ma [1] to the timing at which Indian rocks reached UHP depths at 57 Ma [2], to a reduction in northward drift of the Indian plate at 55 Ma [3]. New interpretations have placed collision as late as 38 Ma [4]. The extent of diachroneity is also disputed, varying from slight [5] to substantial [6]. Two approaches are used here to determine collision, 1) the timing of closure of the Tethys Ocean [7], based on stratigraphic succession, 2) first evidence of Asian derived material deposited on the Indian plate [8], using U-Pb ages of detrital zircon to assess provenance. In Ladakh, Indian plate passive margin limestones of the Mid-Late Paleocene Dibling Formation [9] are overlain by the youngest marine facies of the region, the marine siltstones of the Kong Fm. and the fluvio-deltaic facies of the Chulung La Fm. [8]. The age of the Kong and Chulung La formations is disputed, ranging from P5/6 (56 Ma) [10] to P8 (50.5 Ma) [8]. The provenance is also debated, considered either to be eroded from ophiolitic material from the Indian plate [10] or containing detritus from the Trans-Himalayan arc of the Asian plate [8,11]. We applied biostratigraphy, and U-Pb dating on detrital zircon, to samples from the Kong and Chulung La Formations to define depositional age and provenance. Biostratigraphy identified Asselines A. placentula grande and A. pomeroli, from the SBZ 10 (50.5 to 52.5 Ma) and SBZ 9 (53 Ma) zones respectively, thereby defining a minimum age of collision at 50.5 Ma, based on cessation of marine facies. However, the possibility that these fossils are reworked will be discussed. U-Pb dating of

    Arsenic (As) is a widespread environmental and food chain contaminant and class I, non-threshold carcinogen. Plants accumulate As due to ionic mimicry that is of importance as a measure of phytoremediation but of concern due to the use of plants in alternative medicine. The present study investigated As accumulation in native plants including some medicinal plants, from three districts [Chinsurah (Hoogly), Porbosthali (Bardhman), and Birnagar (Nadia)] of West Bengal, India, having a history of As pollution. A site-specific response was observed for Specific Arsenic Uptake (SAU; mg kg(-1) dw) in total number of 13 (8 aquatic and 5 terrestrial) collected plants. SAU was higher in aquatic plants (5-60 mg kg(-1) dw) than in terrestrial species (4-19 mg kg(-1) dw). The level of As was lower in medicinal plants (MPs) than in non-medicinal plants, however it was still beyond the WHO permissible limit (1 mg kg(-1) dw). The concentration of other elements (Cu, Zn, Se, and Pb) was found to be within prescribed limits in medicinal plants (MP). Among the aquatic plants, Marsilea showed the highest SAU (avg. 45 mg kg(-1) dw), however, transfer factor (TF) of As was the maximum in Centella asiatica (MP, avg. 1). Among the terrestrial plants, the maximum SAU and TF were demonstrated by Alternanthera ficoidea (avg. 15) and Phyllanthus amarus (MP, avg. 1.27), respectively. In conclusion, the direct use of MP or their by products for humans should not be practiced without proper regulation. In other way, one fern species (Marsilea) and some aquatic plants (Eichhornia crassipes and Cyperus difformis) might be suitable candidates for As phytoremediation of paddy fields.

    The purpose of the study was to identify the clinical and etiological profile of uveitis at the apex institute for eye care in India. This is a prospective, prevalence study. 980 consecutive patients with uveitis referred to uvea clinic, Dr. RP Centre for Ophthalmic Sciences (Ophthalmology division, All India Institute of Medical Sciences). Demographic data of each patient were noted and a thorough ocular examination including slit lamp examination and dilated fundus evaluation was carried out. OCT and fluorescein angiography were undertaken whenever indicated. Uveitis was classified based on the anatomic location of inflammation (IUSG classification). Relevant serological and radiological investigations were obtained based on systemic symptomatology, and if the uveitis was recurrent (even in the absence of systemic symptoms). The presence of a systemic disease was confirmed by obtaining an internist consultation. The main outcome measures include pattern of uveitis according to anatomical classification and the etiology. Out of 980 patients with uveitis, 413 (42.14 %) patients had anterior uveitis, 131 (13.36 %) had intermediate uveitis, 165 (16.83 %) had posterior uveitis, 91 (9.2 %) had panuveitis, 47 (4.7 %) had retinal vasculitis, 22 (2.24 %) had scleritis, 17 (1.7 %) had masquerade syndromes, 8 (0.8 %) had keratouveitis, 22 (2.24 %) had sclerokeratouveitis, 19 (1.9 %) had endophthalmitis and 45 (4.5 %) had other causes of inflammation including trauma and intraocular surgery. Out of all uveitic patients definite etiological correlation could be made out in 225 (23 %) patients; thus 77 % were categorised as idiopathic. Only 9 % of all patients were found to have uveitis with an infectious etiology. Amongst infectious causes of uveitis tuberculosis was the leading cause, accounting for sixty percent of all infectious uveitis (approximately 5 % of overall uveitis). Non-infectious uveitis etiology accounted for more than 90 % of all cases with

    The Arghash gold prospect consisting of five gold-bearing vein systems is hosted by Eocene intermediate volcanic and pyroclastic rocks and Late Eocene-Oligocene granitic and dioritic rocks. The vein materials consist mostly of quartz, calcite and minor pyrite. Gold occurs as native particles in quartz, as well as submicroscopic particles in arsenian pyrite, as indicated by microprobe analyses. All auriferous vein systems show similar vein mineralogy and hydrothermal alteration assemblages, implying that they all belong to the same mineralization event in the region. The ä18O compositions of hydrothermal fluid(s) in equilibrium with vein quartz vary from +6.3 to +10.5 per mil. The äD values of the fluid in equilibrium with kaolinite from the immediate altered wall rocks vary from -53 to - 62 per mil. The oxygen isotope values fall in the range commonly accepted for magmatic waters; the calculated äD values overlap between meteoric and magmatic waters. Oxygen and hydrogen isotope compositions similar to those in Arghash can be produced from meteoric waters evolved through interaction with country rocks, boiling, and mixing with magmatic water. The effects of various water/rock ratios on the isotopic composition of the exchanged meteoric water could explain a shift of about +14 per mil in the ä18O values of the mineralizing fluids in the Arghash prospect. Water/rock interaction would also change the äD values of the hydrothermal fluids at low water/rock ratios. In the case of igneous country rocks, as in the Arghash, this process should lead to a shift in the äD of the presumed meteoric waters toward higher values. Boiling will increase the ä18O and äD values of hydrothermal fluids due to fractionation of 16O and H into the vapor phase and decreasing temperature. The magnitude of the enrichment depends on the boiling path and the mechanism of vapor separation. Boiling in Arghash is supported by mineralogical and textural evidences. Gold assays are highest

    The incidence of nonfamilial retinoblastoma (RB) is believed to be higher in developing countries. The reports on association of human papillomavirus (HPV) with RB are limited and contradictory. The aim was to investigate the prevalence of HPV in RB tumor tissue. In the prospective study, consecutive eyes enucleated for RB from patients lacking a family history of RB were enrolled as cases over a 3-year period. Controls included donor eyes obtained from the eye bank. Normal retinal tissue from the donor eyes and tumor tissue from eyes with RB was subjected to DNA isolation. Polymerase chain reaction followed by dot-blot hybridization was performed to detect 21 HPV genotypes. The study cohort included 39 RB and 42 normal retinal tissues. A positive result for HPV-polymerase chain reaction was obtained in 10 (25.6%) tumor tissues and none of the control eyes. HPV-16 was the only subtype detected. Socioeconomic status (P=0.58) or maternal age (P=0.58) was not associated with presence of HPV. All HPV-positive patients had undergone a vaginal delivery (P=0.60). HPV-16 was detected in one-fourth cases of nonfamilial RB. None of the control cases (donor eyes) tested positive. Implication of the presence of HPV in RB tissue and role in carcinogenesis needs further elucidation.

    Aims: To conduct a prospective, community based study in an impoverished urban site in Kolkata (formerly Calcutta) in order to measure the burden of cholera, describe its epidemiology, and search for potential risk factors that could be addressed by public health strategies. Methods: The study population was enumerated at the beginning and end of the study period. Surveillance through five field outposts and two referral hospitals for acute, watery, non-bloody diarrhoea was conducted from 1 May 2003 to 30 April 2004. Data and a stool sample for culture of Vibrio cholerae were collected from each patient. Treatment was provided in accordance with national guidelines. Results: From 62 329 individuals under surveillance, 3284 diarrhoea episodes were detected, of which 3276 (99%) had a stool sample collected and 126 (4%) were culture confirmed cholera. Nineteen (15%) were children less than 2 years of age, 29 (23%) had severe dehydration, and 48 (38%) were hospitalised. Risk factors for cholera included a household member with cholera during the period of surveillance, young age, and lower educational level. Conclusions: There was a substantial burden of cholera in Kolkata with risk factors not easily amenable to intervention. Young children bear the brunt not only of diarrhoeal diseases in general, but of cholera as well. Mass vaccination could be a potentially useful tool to prevent and control seasonal cholera in this community. PMID:15964861

    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

    Gondwana amalgamated along a suite of Himalayan-scale collisional orogens, the roots of which lace the continents of Africa, South America, and Antarctica. The Southern Granulite Terrane of India is a generally well-exposed, exhumed, Gondwana-forming orogen that preserves a record of the tectonic evolution of the eastern margin of the East African Orogen during the Ediacaran-Cambrian (circa 600-500 Ma) as central Gondwana formed. The deformation associated with the closure of the Mozambique Ocean and collision of the Indian and East African/Madagascan cratonic domains is believed to have taken place along the southern margin of the Salem Block (the Palghat-Cauvery Shear System, PCSS) in the Southern Granulite Terrane. Investigation of the structural fabrics and the geochronology of the high-grade shear zones within the PCSS system shows that the Moyar-Salem-Attur shear zone to the north of the PCSS system is early Paleoproterozoic in age and associated with dextral strike-slip motion, while the Cauvery shear zone (CSZ) to the south of the PCSS system can be loosely constrained to circa 740-550 Ma and is associated with dip-slip dextral transpression and north side-up motion. To the south of the proposed suture zone (the Cauvery shear zone), the structural fabrics of the Northern Madurai Block suggest four deformational events (D1-D4), some of which are likely to be contemporaneous. The timing of high pressure-ultrahigh temperature metamorphism and deformation (D1-D3) in the Madurai Block (here interpreted as the southern extension of Azania) is constrained to circa 550-500 Ma and interpreted as representing collisional orogeny and subsequent orogenic collapse of the eastern margin of the East African Orogen. The disparity in the nature of the structural fabrics and the timing of the deformation in the Salem and the Madurai Blocks suggest that the two experienced distinct tectonothermal events prior to their amalgamation along the Cauvery shear zone during the

    We have carried out radioelemental (232Th, 238U, 40K), petrological and geochemical analyses on granitoids and gneisses covering major rock formations of the Bundelkhand craton, central India. Our data reveal that above characteristics are distinct among granitoids (i.e. pink, biotite and grey granitoids) and gneisses (i.e. potassic and sodic types). Pink granitoid is K-feldspar-rich and meta-aluminous to per-aluminous in character. Biotite granitoid is meta-aluminous in character. Grey granitoid is rich in Na-feldspar and mafic minerals, granodiorite to diorite in composition and meta-aluminous in character. Among these granitoids, radioelements (Th, U, K) are highest in pink granitoid (45.0 ± 21.7 ppm, 7.2 ± 3.4 ppm, 4.2 ± 0.4 %), intermediate in biotite granitoid (44.5 ± 28.2 ppm, 5.4 ± 2.8 ppm, 3.4 ± 0.7 %) and lowest in grey granitoid (17.7 ± 4.3 ppm, 4.4 ± 0.6 ppm, 3.0 ± 0.4 %). Among gneisses, potassic-type gneisses have higher radioelements (11.8 ± 5.3 ppm, 3.1 ± 1.2 ppm, 2.0 ± 0.5 %) than the sodic-type gneisses (5.6 ± 2.8 ppm, 1.3 ± 0.5 ppm, 1.4 ± 0.7 %). Moreover, the pink granitoid and the biotite granitoid have higher Th/U (6 and 8, respectively) compared to the grey granitoid (Th/U: 4), implying enrichment of Th in pink and biotite granitoids relative to grey granitoid. K/U among pink, biotite and grey granitoids shows little variation (0.6 × 104, 0.6 × 104, 0.7 × 104, respectively), indicating relatively similar increase in K and U. Therefore, mineralogical and petrological data along with radioelemental ratios suggest that radioelemental variations in these lithounits are mainly related to abundances of the radioactive minerals that have formed by the fractionation of LILE from different magma sources. Based on present data, the craton can be divided into three distinct zones that can be correlated with its evolution in time and space. The central part, where gneisses are associated with metavolcanics of greenstone belt, is

    AIMS Drug related events (DREs) contribute significantly to hospital admissions. These are largely preventable events and require optimum use of the therapeutic agents. The study was conducted to analyze the cost of treatment of DREs. PATIENTS & METHODS All visits to medical emergency department of a tertiary care public sector hospital in northern India were recorded in a prospective, non-interventional manner over a period of 4 months. DREs were recognized and were followed up till their stay in the hospital. Data about the cost generating components of direct and indirect costs of treatment of DREs were collected. The projected cost of treatment of the same DREs in a private sector hospital was estimated and compared. RESULTS Out of 1833 admissions, 92(5.01%) were due to DREs. Maximum cases were due to non compliance (66%) followed by ADR (28%) and drug overdose(6%). The common DREs leading to ED visits were cerebrovascular accident(19.44%), followed by accelerated hypertension(18.36%) and diabetic ketoacidosis(14.04%). Total cost of management of all the 92 DREs in our hospital was calculated to be INR17,37,339(€30,215). The direct cost was INR1,72,961(€3008) and the approximate indirect cost was INR15,64, 378(€27, 206). The projected cost of management of all the 92 DREs was estimated to be INR63,63,872(€1,01, 676) in a private sector hospital. CONCLUSION The study shows that ADEs leading to emergency department visits and hospitalizations constitute a significant economic burden. Training of the patients and the prescribers may lessen the economic burden on the patient as well as the health care system. PMID:19523017

    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

    OBJECTIVE The objective of this study is to determine the correlation of Apgar score with asphyxial hepatic injury and neonatal mortality in moderately and severely asphyxiated newborns. MATERIAL AND METHODS This is a secondary analysis of our prospective observational case-controlled study. Sixteen neonates with severe birth asphyxia (five-minute Apgar ≤3) were compared with either 54 moderate asphyxia neonates (five-minute Apgar >3) or 30 normal neonates. Liver function tests were measured on postnatal days 1, 3, and 10 in the study and control groups. Neonatal mortality was observed in the study and control population. RESULTS Correlation of Apgar score in severely asphyxiated neonates compared with normal Apgar score neonates and moderately asphyxiated neonates for deranged hepatic function showed significant correlation (odds ratio [OR] 4.88, 95% CI 3.26–5.84, P = 0.01 and OR 2.46, 95% CI 1.94–3.32, P = 0.02, respectively). There was a significant increase in serum lactate dehydrogenase (LDH) and total bilirubin on day 1 and serum LDH at age of 10th postnatal life in severely asphyxiated neonates when compared to moderately asphyxiated neonates, whereas there was a significant decrease in total bilirubin and serum albumin on day 3 in severely asphyxiated neonates. There was a significant increase in serum alanine transaminase, serum LDH, and total bilirubin on day 1, serum aspartate transaminase, serum LDH, and total bilirubin on day 3, and International Normalized Ratio on day 10 of postnatal life when severely asphyxiated neonates were compared with normal neonates. There was a significant reduction in total protein and serum albumin on day 1 and direct bilirubin on day 3 in severely asphyxiated neonates when compared with normal neonates. There was a significant increase in neonatal mortality in severely asphyxiated neonates when compared to the other two groups.

    Aims and objective: To determine normal blood pressure (BP) in apparently healthy, asymptomatic school children in the age group of 6–16 years and to determine the correlation of BP values with different sex, weight, height, and body mass index (BMI) and also to find out prevalence of hypertension in school going population. Materials and methods: This prospective, observational study enrolled 3,302 urban children (1,658 boys and 1,644 girls) in the age group of 6–16 years. These were analyzed to study the distribution pattern of systolic blood pressure (SBP) and diastolic blood pressure (DBP) at different ages, sex, weight, height, and BMI. The SBP and DBP were noted as per age and sex. The association was seen between mean SBP and mean DBP with weight, height, and BMI. Information was collected about the family history of hypertension and was correlated with the obtained SBP and DBP readings. Results: The mean SBP in males at 6 years was 99.69 ± 3.62 mm of Hg, at 10 years was 102.20 ± 2.16 mm of Hg, and at 16 years was 115.33 ± 1.26 mm of Hg. The mean SBP in females at 6 years was 96.55 ± 2.86 mm of Hg, at 10 years was 101.16 ± 2.12 mm of Hg, and at 16 years was 112.41 ± 1.06 mm of Hg. The correlation coefficient for relationship between age and SBP in males and females was 0.89 and 0.91, respectively, and for DBP was 0.92 and 0.90, respectively. The correlation coefficient for relationship between height and SBP in males and females was 0.91 and 0.93, respectively, and for DBP was 0.92 and 0.88, respectively. The correlation coefficient for relationship between weight and SBP in males and females was 0.92 and 0.92, respectively, and for DBP was 0.94 and 0.91, respectively. In the nomogram obtained in the study, 95% of study population fall between mean +2SD and −2SD. Conclusion: The blood pressure (BP) (SBP and DBP) tends to increase with age, weight, height, and BMI.

    The relationships between food, nutrition science, and health outcomes have been mapped over the past century. Genomic variation among individuals and populations is a new factor that enriches and challenges our understanding of these complex relationships. Hence, the confluence of nutritional science and genomics-nutrigenomics--was the focus of the OMICS: A Journal of Integrative Biology in December 2008 (Part 1). The 2009 Special Issue (Part 2) concludes the analysis of nutrigenomics research and innovations. Together, these two issues expand the scope and depth of critical scholarship in nutrigenomics, in keeping with an integrated multidisciplinary analysis across the bioscience, omics technology, social, ethical, intellectual property and policy dimensions. Historically, the field of pharmacogenetics provided the first examples of specifically identifiable gene variants predisposing to unexpected responses to drugs since the 1950s. Brewer coined the term ecogenetics in 1971 to broaden the concept of gene-environment interactions from drugs and nutrition to include environmental agents in general. In the mid-1990s, introduction of high-throughput technologies led to the terms pharmacogenomics, nutrigenomics and ecogenomics to describe, respectively, the contribution of genomic variability to differential responses to drugs, food, and environment defined in the broadest sense. The distinctions, if any, between these newer fields (e.g., nutrigenomics) and their predecessors (e.g., nutrigenetics) remain to be delineated. For nutrigenomics, its reliance on genome-wide analyses may lead to detection of new biological mechanisms governing host response to food. Recognizing "genome-environment interactions" as the conceptual thread that connects and runs through pharmacogenomics, nutrigenomics, and ecogenomics may contribute toward anticipatory governance and prospective real-time analysis of these omics fields. Such real-time analysis of omics technologies and

    Arabia is bounded by the Dead Sea Transform (DST) to the west and by the Owen Fracture Zone (OFZ) to the east. These present-day major strike-slip fault systems activated during the Plio-Pleistocene, which contrasts with the age of inception of strike-slip motion, assumed to begin around 13-18 Ma for the DST and around 20 Ma at the edge of the Owen-Murray Ridge (OMR) for the India-Arabia plate boundary. This discrepancy between the age of the active strike-slip systems and the age of inception of strike-slip motion raises the question of the kinematic driver for the transition between successive generations of strike-slip faults. Using a recent mutibeam and seismic dataset crossing the OFZ and the OMR, we provide a new geodynamic framework for the Miocene to present-day structural evolution of the India-Arabia plate boundary, and highlight some similarities with the structural evolution of the DST. We first document a Late Miocene episode of uplift of the OMR uplift along the Miocene India-Arabia plate boundary. The onset of this uplift is coeval with a plate reorganization event marked by the onset of intra-plate deformation in the Central Indian Ocean. The OFZ emplaced around 3 Ma, with major pull-apart basins opening (20°N Basin, Dalrymple Trough) dated at 2.4 Ma by far-field correlation with ODP Sites. The opening of pull-apart basins is coeval with the last structural reorganization of the Makran accretionnary wedge, marked by the regional M-unconformity, and with a major intensification of the Indian monsoon. A Late Miocene episode of folding is also recognized at the Lebanon ranges prior to the onset of the present-day DST, which occurred in the Late Pliocene-Early Pleistocene. The similarities between the geological history of the India-Arabia plate boundary and the DST in the Late Miocene and the Late Pliocene-Early Pleistocene suggest that both plate boundaries recorded the same kinematic changes. Late Miocene (i.e. Tortonian) deformation is widely

  7. The interior and evolution of Enceladus: Current knowledge and future prospects (Invited)

    The nature and evolution of the interior of Enceladus, and especially that of any liquid water, is a topic of great astrobiological significance. Cassini observations of salty grains in the E-ring strongly suggest the presence of subsurface liquid [1], though this liquid may only be regional [2,3] rather than global in extent. Here I will focus on three questions of comparable importance. 1. How can its heat budget be explained? The current heat output from the South Polar region [4] greatly exceeds the equilibrium tidal heat production [5]. There are two solutions to this paradox: either Enceladus produces heat intermittently; or it produces heat at a constant rate, but gets rid of that heat intermittently. Enceladus does not undergo episodic tidal heating of the kind which may occur at Io [6], for either a convective [7] or a conductive ice shell. It may undergo episodic heating whenever the growing tidal stresses cross a critical threshold to initiate fault motion [8]. Alternatively, convection on Enceladus driven by constant heating may result in episodic overturn and pulsed heat loss [9]. Either solution implies a duty cycle roughly consistent with observations of 40Ar in the plume [10]. One way of distinguishing between these two solutions is astrometric observations, as at Io [11]. If the current tidal heating rate at Enceladus is that measured by Cassini [4], the eccentricity damping results in a fractional change in mean motion of ~6e-11 /yr, potentially measurable with ground-based observations. 2. Is the ice shell convecting? The ice shell of Enceladus is marginally unstable to convection. A convective shell is dissipative and also results in rapid reduction of ice shell thickness contrasts. Regional topographic anomalies, especially at the South Pole [2,12], are suggestive of shell thickness contrasts and a conductive shell. A conductive shell is also more compatible with the long-term orbital evolution of Enceladus [13] and results in a longer

    The Tian Shan range is an inherited intracontinental structure reactivated by the far-field effects of India-Asia collision. A growing body of thermochronology and magnetostratigraphy datasets shows the range grew through several tectonic pulses since ~25 Ma, however the early Cenozoic history remains poorly constrained. Particularly enigmatic is the time-lag between the Eocene India-Asia collision and the Miocene onset of Tian Shan exhumation. This peculiar period is potentially recorded along the southwestern Tian Shan piedmont. There, recently dated late Eocene marine deposits of the proto-Paratethys epicontinental sea transition to continental foreland basin sediments of unknown age. We provide magnetostratigraphic dating of these continental sediments from the 1700-m-thick Mine section integrated with previously published detrital apatite fission track and U/Pb zircon ages. The most likely correlation to the geomagnetic polarity time scale indicates an age span from 20.8 to 13.3 Ma with a marked accumulation rate increase at 19-18 Ma. This implies the entire Oligocene period is missing between the last marine and first continental sediments, as suggested by previous southwestern Tian Shan results. This differs from the southwestern Tarim basin where Eocene marine deposits are continuously overlain by late Eocene-Oligocene continental sediments. This supports a simple evolution model of the western Tarim basin with Eocene-Oligocene foreland basin activation to the south related to northward thrusting of the Kunlun Shan, followed by early Miocene activation of northern foreland basin related to overthrusting of the south Tian Shan. Our data also support southward propagation of the Tian Shan piedmont from 20-18 Ma that may relate to motion on the Talas Fergana Fault. The coeval activation of a major right-lateral strike-slip system allowing indentation of the Pamir Salient into the Tarim basin, suggest far-field deformation from the India-Asia collision zone

    The atmospheric boundary layer (ABL) over a given coastal station is influenced by the presence of mesoscale sea breeze circulation, together with the local and synoptic weather, which directly or indirectly modulate the vertical thickness of ABL (z ABL). Despite its importance in the characterization of lower tropospheric processes and atmospheric modeling studies, a reliable climatology on the temporal evolution of z ABL is not available over the tropics. Here, we investigate the challenges involved in determination of the ABL heights, and discuss an objective method to define the vertical structure of coastal ABL. The study presents a two year morphology on the diurnal evolution of the vertical thickness of sea breeze flow (z SBF) and z ABL in association with the altitudes of lifting condensation level (z LCL) over Thiruvananthapuram (8.5∘ N, 76.9∘ E), a representative coastal station on the western coastline of the Indian sub-continent. We make use of about 516 balloon-borne GPS sonde measurements in the present study, which were carried out as part of the tropical tropopause dynamics field experiment under the climate and weather of the sun-earth system (CAWSES)-India program. Results obtained from the present study reveal major differences in the temporal evolution of the ABL features in relation to the strength of sea breeze circulation and monsoonal wind flow during the winter and summer monsoon respectively. The diurnal evolution in z ABL is very prominent in the winter monsoon as against the summer monsoon, which is attributed to the impact of large-scale monsoonal flow over the surface layer meteorology. For a majority of the database, the z LCL altitudes are found to be higher than that of the z ABL, indicating a possible decoupling of the ABL with the low-level clouds.

    Soils from two sites viz. Kotumsar and Tirathgarh, located ∼5 km apart in a tropical reserve forest (18°52‧N, 81°56‧E) in central India, have been explored for soil organic carbon (SOC) content, its mean residence time (MRT) and the evolution of stable carbon isotopic composition (δ13C). SOC stocks in the upper 30 cm of soil layers are ∼5.3 kg/m2 and ∼3.0 kg/m2; in the upper 110 m are ∼10.7 kg/m2 and ∼7.8 kg/m2 at Kotumsar and Tirathgarh, respectively. SOC decreases with increasing depth. Bomb carbon signature is observed in the upper ∼10 cm. Organic matters in the top soil layers (0-10 cm) have MRTs of the order of a century which increases gradually with depths, reaching 3500-5000 yrs at ∼100 cm. δ13C values of SOC increase with depth, the carbon isotopic fractionation is obtained to be -1.2‰ and -3‰ for soils at Kotumsar and Tirathgarh, respectively, confirmed using Rayleigh isotopic fractionation model. The evolution of δ13C in soils was also studied using a modified Rayleigh fractionation model incorporating a continuous input into the reservoir: the depth profiles of δ13C for SOC show that the input organic matter from surface into the deeper soil layers is either insignificant or highly labile and decomposes quite fast in the top layers, thus making little contribution to the residual biomasses of the deeper layers. This is an attempt to understand the distillation processes that take place in SOC, assess the extent of decomposition by microbes and effect of percolation of fresh organic matter into dipper soil layers which are important for stable isotope based paleoclimate and paleovegetation reconstruction and understanding the dynamics of organic carbon in soils.

    Objectives We prospectively examined the impact of type 2 diabetes compared with metabolic syndrome (MetS) on the development of vascular disease over 4 years as determined by anatomic and functional markers of vascular disease. By comparing the vascular outcomes of the 2 disorders, we seek to determine the independent effect of elevated glucose levels on vascular disease. Setting 2 primary care centres in Salamanca, Spain. Participants We performed a prospective observational study involving 112 patients (68 with type 2 diabetes and 44 with MetS) who were followed for 4 years. Primary and secondary outcome measures Measurements included blood pressure, blood glucose, lipids, smoking, body mass index, waist circumference, Homeostasis Model Assessment Insulin Resistance (HOMA-IR), hs-c-reactive protein and fibrinogen levels. We also evaluated vascular, carotid intima media thickness (IMT), pulse wave velocity (PWV) and ankle/brachial index, heart and renal target organ damage (TOD). The haemodynamic parameters were central (CAIx) and peripheral (PAIx) augmentation indices. Results In year 4, participants with type 2 diabetes had increased IMT thickness. These patients had more plaques and an IMT>0.90 mm. In participants with MetS, we only found an increase in the number of plaques. We found no changes in PWV, CAIx and PAIx. The patients with diabetes had a greater frequency of vascular TOD. There were no differences neither in renal nor cardiac percentage of TOD in the patients with MetS or diabetes mellitus type 2. Conclusions This prospective study showed that the evolution of vascular TOD is different in participants with type 2 diabetes compared with those with MetS. While IMT and PWV increased in type 2 diabetes, these were not modified in MetS. The renal and cardiac TOD evolution, as well as the PAIx and CAIx, did not change in either group.

  14. Insights into the Crustal Structure and Geodynamic Evolution of the Southern Granulite Terrain, India, from Isostatic Considerations

    The Southern Granulite Terrain of India, formed through an ancient continental collision and uplift of the earth's surface, was accompanied by thickening of the crust. Once the active tectonism ceased, the buoyancy of these deep crustal roots must have supported the Nilgiri and Palani-Cardamom hills. Here, the gravity field has been utilized to provide new constraints on how the force of buoyancy maintains the state of isostasy in the Southern Granulite Terrain. Isostatic calculations show that the seismically derived crustal thickness of 43-44 km in the Southern Granulite Terrain is on average 7-8 km more than that required to isostatically balance the present-day topography. This difference cannot be solely explained applying a constant shift in the mean sea level crustal thickness of 32 km. The isostatic analysis thus indicates that the current topography of the Southern Granulite Terrain is overcompensated, and about 1.0 km of the topographic load must have been eroded from this region without any isostatic readjustment. The observed gravity anomaly, an order of magnitude lower than that expected (-125 mGal), however, shows that there is no such overcompensation. Thermal perturbations up to Pan-African, present-day high mantle heat flow and low Te together negate the possible resistance of the lithosphere to rebound in response to erosional unloading. To isostatically compensate the crustal root, compatible to seismic Moho, a band of high density (2,930 kg m-3) in the lower crust and low density (3,210 kg m-3) in the lithospheric mantle below the Southern Granulite Terrain is needed. A relatively denser crust due to two distinct episodes of metamorphic phase transitions at 2.5 Ga and 550 Ma and highly mobilized upper mantle during Pan-African thermal perturbation reduced significantly the root buoyancy that kept the crust pulled downward in response to the eroded topography.

    Genome sequences of three episomal Banana streak MY virus (BSMYV) isolates sampled from triploid banana hybrids (Chini Champa: AAB; Malbhog: AAB and Monthan: ABB), grown in North-East and South India are reported in this study by sequence-independent improved rolling circle amplification (RCA). RCA coupled with restriction fragment length polymorphism revealed diverse restriction profiles of five BSMYV isolates. Nucleotide substitution rates of BSMYV subpopulation and Banana streak OL virus subpopulation was 7.13 × 10(-3) to 1.59 × 10(-2) and 2.65 × 10(-3) to 5.49 × 10(-3), respectively, for the different coding regions. Analysis of the genetic diversity of banana and sugarcane badnaviruses revealed a total of 32 unique recombination events among banana and sugarcane badnaviruses (inter BSV-SCBV), in addition to the extensive recombination with in banana streak viruses and sugarcane bacilliform viruses (intra-BSV and intra-SCBV). Many unique fragments were shown to contain similar ruminant sequence fragments which indicated the possibility that the two groups of badnaviruses or their ancestors to colonise same host before making the host shift. The distribution of recombination events, hot-spots (intergenic region and C-terminal of ORF3) as well as cold-spots (distributed in ORF3) displayed the mirroring of recombination traces in both group of badnaviruses. These results support the hypothesis of relatedness of banana and sugarcane badnaviruses and the host and geographical shifts that followed the fixation of the species complex appear to be a recent event.

    WRF-Chem has been used to simulate O3 and its precursors, NOx and CO and meteorological variables over the sub-Himalayn North-Eastern region of India including Bangladesh for the year 2012. The model simulation is compared with the observations carried at a location Dibrugarh (27.3ºN, 94.6ºE, 111 m amsl). WRF Chem is capable of simulating the diurnal variability in surface O3 in all the seasons with a good correlation (R2>0.57) between the simulated and observed O3. The model is found to capture the observed seasonal variations in O3 concentrations with maximum during the spring and minimum in monsoon. However, the model overestimates both the minimum and maximum levels by >10ppb in monsoon season and > 20ppb in all other three seasons. Simulated NO is underestimated, mostly during the nighttime in all three seasons (5-20 ppb) except the monsoon (~5ppb) season, when it is overestimated. Simulated NO2 and CO on the other hand, is underestimated in all the seasons. The observed difference may be contributed by the bias in the estimation of the O3 precursors, NOx and CO in the emission inventories or the error in the simulation of the meteorological variables which influences O3 concentration. For example, in the pre-monsoon and winter season, the model simulated shortwave flux overestimates the observation by ~500 Wm-2. While in the monsoon and post monsoon season, simulated shortwave flux is equivalent to the observation. The model predicts high wind speed in all the seasons especially during night-time as against observation. In the post-monsoon and winter season, the simulated wind pattern is reverse to observation with daytime low and night-time high values. Rainfall is overestimated in all the seasons. The night-time overestimation of O3 over this location may also be due to inadequacy of the model's chemistry to properly simulate the night-time level over this location.

    South Asia, particularly the Indo-Gangetic Plains and foothills of the Himalayas, has been found to be a major source of pollutant gases and particles affecting the regional as well as the global climate. Inventories of greenhouse gases for the South Asian region, particularly the sub-Himalayan region, have been inadequate. Hence, measurements of the gases are important from effective characterization of the gases and their climate effects. The diurnal, seasonal, and annual variation of surface level O3 measured for the first time in northeast India at Dibrugarh (27.4° N, 94.9° E, 111 m amsl), a sub-Himalayan location in the Brahmaputra basin, from November 2009 to May 2013 is presented. The effect of the precursor gases NO x and CO measured simultaneously during January 2012-May 2013 and the prevailing meteorology on the growth and decay of O3 has been studied. The O3 concentration starts to increase gradually after sunrise attaining a peak level around 1500 hours LT and then decreases from evening till sunrise next day. The highest and lowest monthly maximum concentration of O3 is observed in March (42.9 ± 10.3 ppb) and July (17.3 ± 7.0 ppb), respectively. The peak in O3 concentration is preceded by the peaks in NO x and CO concentrations which maximize during the period November to March with peak values of 25.2 ± 21.0 ppb and 1.0 ± 0.4 ppm, respectively, in January. Significant nonlinear correlation is observed between O3 and NO, NO2, and CO. National Atmospheric and Oceanic Administration Hybrid Single-Particle Lagrangian Integrated Trajectory back-trajectory and concentration weighted trajectory analysis carried out to delineate the possible airmass trajectory and to identify the potential source region of NO x and O3 concentrations show that in post-monsoon and winter, majority of the trajectories are confined locally while in pre-monsoon and monsoon, these are originated at the Indo-Gangetic plains, Bangladesh, and Bay of Bengal.

    This study deals with the tectono-metamorphic evolution of Sapphirine-cordierite-bearing metapelite granulite at Perumalmalai, south India, that occurs as enclave within deformed migmatitic enderbite gneiss of Kodaikanal massif, Madurai granulite block (MB), south India. Pre-peak mineral paragenesis is represented by an inclusion assemblage of sillimanite + plagioclase + Ti-rich biotite ±quartz in Al-rich orthopyroxene. Dehydration melting of biotite marked the onset of ultra-high temperature metamorphism (M1A, ~1000 °C, 10 Kbar). Early stage of retrograde metamorphism (M1B) is characterized by the development of type1-symplectite and corona textures. In type1-symplectite an innermost vermicular sapphirine (Spr - XMg: 0.90, Al/Si: 6.17) - cordierite (Crd) symplectite on sillimanite is followed by cordierite (XMg: 0.94) moat. A meso-perthitic layer laced the interface between cordierite moat and orthopyroxene porphyroblast, the latter showing prominent rim-ward decrease in Al2O3 (up to 3 wt%). The cordierite rim at the interface between sillimanite and orthopyroxene characterizes corona texture. Type1-symplectite and corona domains are circumnavigated by Ti-poor biotite (TiO2: ~3.2 wt%) showing shape preferred alignment, and set in a feldspar matrix showing wide compositional range. By implication, leucosome crystallization was possibly prolonged and enhanced by deformation. Type1-symplectite and corona textures were resulted from melt-solid interaction or silica-metasomatism during early stage of retrogression, Opx+Sil = Spr+Crd → Opx+Sil+melt = Crd. The retrograde metamorphism is constrained at 9 kbar and 950°C, implying an early stage of near-isothermal decompression. Late stage retrograde metamorphism (M2) is also characterized by symplectite textures, type2-symplectite, with innermost sapphirine-cordierite symplectite followed by cordierite corona. Sapphirine in type2-symplectite domain (XMg: 0.89; Al/Si: 5.92), which occurs as inclusion in Opx, is

    The Dharwar Craton in southern India is known to have formed by the accretion of East Dharwar Craton (EDC) and West Dharwar Craton (WDC) at ca. 2500 Ma. This accretion occurred along the Chitradurga Boundary Fault (CBF), which is considered to demarcate the WDC from the EDC (Chadwick et al., 2003). In recent years, several structural studies integrating field, anisotropy of magnetic susceptibility (AMS) and paleostress analyses have been carried out on metabasalts and granite (Mulgund Granite) in the vicinity of Gadag town that lie in WDC, i.e., west of CBF (Mondal and Mamtani, 2013; 2014; 2016). These have established the following: (a) Rocks around Gadag have undergone three deformation events - D1/ D2 was due to NE-SW compression that led to the development of NW-SE fabric elements in the metabasalts and granitic rocks; the latter is manifested in the magnetic foliation recorded from AMS. D3 was on account of NW-SE compression that led to doubly plunging magnetic lineations. (b) The metabasalts are replete with quartz veins many of which are gold bearing. These dominantly strike in NW-SE direction and formed due to dilation during D3. (c) Strain partitioning took place at the contacts between the Mulgund Granite and surround rocks resulted in development of oblique-slip normal faults within the granite during late stages of D3. In comparison to such in-depth knowledge of the WDC, structural evolution of the rocks of EDC has remained to be poorly understood. Therefore, in the present study, the authors have focused on rocks of the Koppal region that lie to the east of CBF in EDC. The objectives of the research are to evaluate the deformation fabric in the region and compare the results with those of the WDC (cited above) to understand the kinematics associated with formation of the Dharwar Craton. To fulfill this objective, the authors have investigated Peninsular Gneisses and granitoids (Koppal Granitoid) around Koppal town (61 km east of Gadag). The field

    Determination of the peak thermal condition is vital in order to understand tectono-thermal evolution of the Himalayan belt. The Lesser Himalayan Sequence (LHS) in the Western Arunachal Pradesh, being rich in carbonaceous material (CM), facilitates the determination of peak metamorphic temperature based on Raman spectroscopy of carbonaceous material (RSCM). In this study, we have used RSCM method of Beyssac et al. (J Metamorph Geol 20:859-871, 2002a) and Rahl et al. (Earth Planet Sci Lett 240:339-354, 2005) to estimate the thermal history of LHS and Siwalik foreland from the western Arunachal Pradesh. The study indicates that the temperature of 700-800 °C in the Greater Himalayan Sequence (GHS) decreases to 650-700 °C in the main central thrust zone (MCTZ) and decreases further to <200 °C in the Mio-Pliocene sequence of Siwaliks. The work demonstrates greater reliability of Rahl et al.'s (Earth Planet Sci Lett 240:339-354, 2005) RSCM method for temperatures >600 and <340 °C. We show that the higher and lower zones of Bomdila Gneiss (BG) experienced temperature of ~600 °C and exhumed at different stages along the Bomdila Thrust (BT) and Upper Main Boundary Thrust (U.MBT). Pyrolysis analysis of the CM together with the Fission Track ages from upper Siwaliks corroborates the RSCM thermometry estimate of ~240 °C. The results indicate that the Permian sequence north of Lower MBT was deposited at greater depths (>12 km) than the upper Siwalik sediments to its south at depths <8 km before they were exhumed. The 40Ar/39Ar ages suggest that the upper zones of Se La evolved ~13-15 Ma. The middle zone exhumed at ~11 Ma and lower zone close to ~8 Ma indicating erosional unroofing of the MCT sheet. The footwall of MCTZ cooled between 6 and 8 Ma. Analyses of P-T path imply that LHS between MCT and U.MBT zone falls within the kyanite stability field with near isobaric condition. At higher structural level, the temperatures increase gradually with P-T conditions in the

    Late Quaternary landform evolution in monsoon-dominated middle Satluj valley is reconstructed using the fragmentary records of fluvial terraces, alluvial fans, debris flows, paleo-flood deposits, and epigenetic gorges. Based on detailed field mapping, alluvial stratigraphy, sedimentology and optical chronology, two phases of fluvial aggradations are identified. The older aggradation event dated between ˜13 and 11 ka (early-Holocene), occurred in the pre-existing topography carved by multiple events of erosion and incision. Climatically, the event corresponds to the post-glacial strengthened Indian summer monsoon (ISM). The younger aggradation event dated between ˜5 and 0.4 ka (mid- to late-Holocene), was during the declining phase of ISM. The terrain witnessed high magnitude floods during transitional climate (˜6.5-7 ka). The fluvial sedimentation was punctuated by short-lived debris flows and alluvial fans during the LGM (weak ISM), early to mid-Holocene transition climate and mid- to late-Holocene declining ISM. Based on the terrace morphology, an event of relatively enhanced surface uplift is inferred after late Holocene. The present study suggests that post-glacial landforms in the middle Satluj valley owe their genesis to the interplay between the climate variability and local/regional tectonic interactions.

    Detailed geochemical analysis of groundwater beneath 1223 km2 area in southern Bengal Basin along with statistical analysis on the chemical data was attempted, to develop a better understanding of the geochemical processes that control the groundwater evolution in the deltaic aquifer of the region. Groundwater is categorized into three types: `excellent', `good' and `poor' and seven hydrochemical facies are assigned to three broad types: `fresh', `mixed' and `brackish' waters. The `fresh' water type dominated with sodium indicates active flushing of the aquifer, whereas chloride-rich `brackish' groundwater represents freshening of modified connate water. The `mixed' type groundwater has possibly evolved due to hydraulic mixing of `fresh' and `brackish' waters. Enrichment of major ions in groundwater is due to weathering of feldspathic and ferro-magnesian minerals by percolating water. The groundwater of Rajarhat New Town (RNT) and adjacent areas in the north and southeast is contaminated with arsenic. Current-pumping may induce more arsenic to flow into the aquifers of RNT and Kolkata cities. Future large-scale pumping of groundwater beneath RNT can modify the hydrological system, which may transport arsenic and low quality water from adjacent aquifers to presently unpolluted aquifer.

    We investigate the microtextural-chemical features of partially serpentinized harzburgites from the lower ultramafic unit of the Mesoarchean Nuasahi Massif, eastern India, in order to understand the role of reacting fluid composition and temperature on the phase evolution across replacement interfaces during progressive alteration. Two distinct types of pseudomorphic replacement textures are identified. Type-1 replacement texture was developed after primary orthopyroxene and is composed of talc + olivine + lizardite + tremolite + magnetite. Primary olivine was replaced by mesh-textured Mg-rich lizardite + magnetite at the center of the olivine grains and successive layers of relatively Fe-rich lizardite, magnesite, and calcite toward olivine rims, defining type-2 replacement texture. The Nuasahi harzburgite was initially out-of-equilibrium with respect to H2O-CO2-bearing reacting solution and the secondary compositions have mainly evolved in the CaO-MgO-FeO-SiO2-Al2O3-H2O-CO2 system as a result of fluid-rock interaction. The alteration process across orthopyroxene interfaces has started at relatively higher temperature conditions (400 < T < 675 °C) than that at primary olivine interface (T ≤ 330 °C). Each replacement process across reaction interfaces was controlled via an interface-coupled dissolution-precipitation mechanism. The sequential development of different secondary compositions in these replacement rims indicates a micrometer-scale variation in silica activity and H2O/CO2(aq) ratio in the solution across replacement interfaces. The Fe2 + Mg- 1 chemical exchange potential of the equilibrating system plays an important role in dictating the Fe/Mg ratio of the secondary compositions and the molar proportions of magnetite. The precipitation of tremolite and calcite in some isolated areas reflects a variation in Ca activity in the reacting fluid. The precipitation of carbonates may also be associated with an increase in pH in the interfacial solution. The

    The mechanisms leading to disability and the long-term efficacy and safety of disease modifying drugs (DMDs) in multiple sclerosis (MS) are unclear. We aimed at building a prospective cohort of MS patients with standardized collection of demographic, clinical, MRI data and body fluids that can be used to develop prognostic indicators and biomarkers of disease evolution and therapeutic response. The Swiss MS Cohort (SMSC) is a prospective observational study performed across seven Swiss MS centers including patients with MS, clinically isolated syndrome (CIS), radiologically isolated syndrome or neuromyelitis optica. Neurological and radiological assessments and biological samples are collected every 6-12 months. We recruited 872 patients (clinically isolated syndrome [CIS] 5.5%, relapsing-remitting MS [RRMS] 85.8%, primary progressive MS [PPMS] 3.5%, secondary progressive MS [SPMS] 5.2%) between June 2012 and July 2015. We performed 2,286 visits (median follow-up 398 days) and collected 2,274 serum, plasma and blood samples, 152 cerebrospinal fluid samples and 1,276 brain MRI scans. 158 relapses occurred and expanded disability status scale (EDSS) scores increased in PPMS, SPMS and RRMS patients experiencing relapses. Most RRMS patients were treated with fingolimod (33.4%), natalizumab (24.5%) or injectable DMDs (13.6%). The SMSC will provide relevant information regarding DMDs efficacy and safety and will serve as a comprehensive infrastructure available for nested research projects.

    The government of India decided to launch a project to implement 16 full-scale Upflow Anaerobic Sludge Blanket (UASB) reactors (with a total capacity of 598,000 m(3)/d) in the Yamuna River basin under its Yamuna Action Plan (YAP). A polishing pond called the Final Polishing Unit (FPU) was utilized for post-treatment. This paper evaluates the sewage treatment efficiency of the combined system of full-scale UASB reactors and polishing ponds under Indian climatic conditions. Results have shown that the effluent from the sewage treatment plants (STPs) investigated failed to comply with applicable discharge standards in terms of BOD, SS, and fecal coliform removal. Therefore, it is proposed that such proper operation and maintenance as removing excess sludge and scum be conducted in order to increase treatment efficiency. Moreover, trained and experienced workers are also required to operate and maintain the systems, along with a scientific approach.

    The growth of a collisional mountain belt like the Himalaya is dynamically coupled both to tectonics and climate and can result in strong temporal variations in the delivery of sediment to intermontane basins and the foreland. Orogenic critical taper models have been helpful to explain the processes controlling the evolution of mountain fronts in such settings. Rapid and voluminous sediment accumulations might destabilize the orogenic wedge and force architectural re-organization by outward propagation of the deformation front, while basin evacuation can induce out-of-sequence-thrusting to return the wedge to a critical taper. Structural reentrants along the Himalayan front are promising locations to study sediment delivery, storage, and sediment-evacuation mechanisms, as those areas commonly expose extensive transiently stored foreland-basin sediments. The Kangra re-entrant in the NW Sub-Himalaya hosts intermontane valley fills of Pleistocene age, eroded from the Dhauladhar Range. The sediments were unconformably deposited on top of Neogene foreland-basin sediments (i.e. the Siwaliks) in the hanging wall of the NW-SE striking Jwalamukhi Thrust. This major sediment accumulation phase appears to have preceded a phase of sediment evacuation in the course of episodic re-incision into the fill unit, which carved a series of fill-terrace levels. Angular unconformities, differential fluvial incision, tilted fluvial terraces, drainage re-organization, and steepened river segments in the hanging wall of the Jwalamukhi Thrust indicate post-depositional shortening and uplift in the Kangra re-entrant. From this evidence, we infer a primary importance of the Jwalamukhi Thrust in controlling the Quaternary sediment deposition in the Kangra re-entrant - however, we cannot exclude the influence of climate as the main trigger for sediment aggradation and subsequent excavation. However, knickpoints and steep river-channel gradients crossing other tectonic structures within the

    The structural style or architecture of the Neogene-Quaternary foreland basin is studied in the Kameng River section of Arunachal Pradesh. The Kimi, Dafla-Subansiri, and Kimin formations correspond to Lower, Middle and Upper Siwaliks. The outcrop scale structures from the Main Boundary Thrust (MBT) towards S shows an overall ramp and flat geometry. The intervening strata between two parallel thrust faults (roof thrust and floor thrust) are sub-parallel. The individual subsidiary faults in imbricate fashion (horses) occur as planar units with straight sides. These duplex structures are significant manifestation of the processes involved in the internal domain of the Siwalik rocks and they represent the mechanism of the slip transfer processes from one glide horizon at depth to another at shallower depth. This process of slip transfer and formation of horses are responsible for the formation of structural thickening, duplex growth and mass addition to the moving thrust complex. In the present area the Siwalik strata showing duplex structures have undergone structural thickness in their internal domain mainly in Dafla formation. The lithology in the foreland basin dominantly composed of the sandstones (Greywacke and lithic -arenite), siltstone, claystone, carbonaceous shale, boulder beds in the upper part. In the microscopic scale, the lithological response in the structural development is well documented as pressure solution seams, elongated quartz and feldspar grains, bent micas, kinked biotites, strained quartz grains, healed grains, and micro-fractures. The basement asperities play a significant role as the moving thrust front produced a major lateral ramp. The differential movement of the mountain front on both sides of the ramp is visible in the field as the mountain front of the western part of the Kameng River move more southeastward compared to the eastern part.

    An inverted metamorphic gradient is commonly preserved where the high-grade Greater Himalayan Crystalline Sequence (GHCS) overthrusts the Lesser Himalayan foreland. This structural break (the Main Central Thrust, or MCT) is a key feature of Himalayan tectonics, generally considered to have taken up at least 200-300 km of shortening since the Early Miocene. The timing of displacement along the MCT and its relationship with inverted metamorphism is debated, with existing temperature inversion models requiring either (a) post-metamorphic faulting along young shear zones; (b) continual or episodic syn-metamorphic thrust development; or (c) single phase pre- to syn-metamorphic thrusting and subsequent thermal relaxation. Here, we use the P-T-t evolution of individual rock samples to study the contrasting histories of the GHCS and LHS units and deduce the relationship between metamorphism and thrusting. The Sutlej River Valley exposes an inverted metamorphic succession consisting of a 9-km thick amphibolite-facies core (the GHCS), structurally underlain by greenschist and amphibolite-facies Lesser Himalayan Sequence (LHS) metapelites which preserve garnet-in, staurolite-in and kyanite/sillimanite-in isograds. The GHCS displays kyanite-in and sillimanite-in isograds, with migmatisation at the top of the sequence. A major thrust-zone (interpreted as the MCT) separates the LHS from the GHCS. The application of rim-thermobarometry to Sutlej samples identifies both the inverted metamorphic gradient in the LHS and GHCS units, and the inherent frailty of cation-exchange thermobarometers when studying high-grade rocks that have been subjected to subsequent retrograde diffusion. The construction of pseudosections and contouring of mineral composition isopleths, however, identifies the PT-paths that both units have taken, allowing a detailed reconstruction of the burial and uplift histories of the units that constitute the MCT-zone.

    Detailed field mapping of glacial and paraglacial landforms supported by optical and radiocarbon dating is used to reconstruct the history of late Quaternary glaciation and landform evolution in the Trans Himalayan region of the upper Dhauliganga valley. The study identifies four events of glaciations with decreasing magnitude which are termed as Purvi Kamet Stage -Ia (PKS-Ia), PKS-Ib, PKS-II, PKS-III and PKS-IV respectively. The oldest PKS-Ia and Ib are assigned the Marine Isotopic Stgae-3 (MIS-3), the PKS-II to the Last Glacial Maximum (MIS-2), PKS-III dated to 7.9 ± 0.7 ka, and the PKS-IV is dated to 3.4 ± 0.3 ka and 1.9 ± 0.2 ka respectively. The largest valley glaciations viz. the (PKS-Ia) occurred during the strengthened summer monsoon corresponding to the MIS-3, following this, the recessional moraines (PKS-Ib) represent the gradual decline in summer monsoon towards the later part of MIS-3. The valley responded to the global Last Glacial Maximum (LGM), which is represented by the PKS-II moraine implying the influence of strengthened mid-latitude westerlies during the LGM. The post-LGM deglaciation was associated with the onset of summer monsoon and is represented by the deposition of four distinct outwash gravel terraces. The early Holocene PKS-III glaciation occurred around 7.9 ± 0.7 ka and broadly coincides with the early Holocene cooling event (8.2 ka). This was followed by the deposition of stratified scree deposits and the alluvial fan (between 5.5 ka and 3 ka) during the mid to late Holocene aridity. This was followed by marginal re-advancement of the valley glacier (viz. PKS-IV) during the late Holocene cool and moist climate. Although glaciers respond to a combination of temperature and precipitation changes, however during the Holocene it seems that temperature played a major role in driving the glaciation.

    This prospective study was carried out from October 2003 to December 2005 and involved a cohort of 946 individuals of both genders, aged 1-89 years, from an endemic area for American visceral leishmaniasis (AVL), in Pará State, Brazil. The aim of the study was to analyze the dynamics of the clinical and immunological evolution of human Leishmania (L.) infantum chagasi infection represented by the following clinical-immunological profiles: asymptomatic infection (AI); symptomatic infection (SI=AVL); subclinical oligosymptomatic infection (SOI); subclinical resistant infection (SRI); and indeterminate initial infection (III). Infection diagnosis was determined by the indirect fluorescent antibody test and leishmanin skin test. In total, 231 cases of infection were diagnosed: the AI profile was the most frequent (73.2%), followed by SRI (12.1%), III (9.9%), SI (2.6%) and SOI (2.2%). The major conclusion regarding evolution dynamics was that the III profile plays a pivotal role from which the cases evolve to either the resistant, SRI and AI, or susceptible, SOI and SI, profiles; only one of the 23 III cases evolved to SI, while most evolved to either SRI (nine cases) or SOI (five cases) and eight cases remained as III.

    Obesity and weight gain are serious concerns after solid organ transplantation (Tx); however, no unbiased comparison regarding body weight parameter evolution across organ groups has yet been performed. Using data from the prospective nationwide Swiss Transplant Cohort Study, we compared the evolution of weight parameters up to 3 years post-Tx in 1359 adult kidney (58.3%), liver (21.7%), lung (11.6%), and heart (8.4%) recipients transplanted between May 2008 and May 2012. Changes in mean weight and body mass index (BMI) category were compared to reference values from 6 months post-Tx. At 3 years post-Tx, compared to other organ groups, liver Tx recipients showed the greatest weight gain (mean 4.8±10.4 kg), 57.4% gained >5% body weight, and they had the highest incidence of obesity (38.1%). After 3 years, based on their BMI categories at 6 months, normal weight and obese liver Tx patients, as well as underweight kidney, lung and heart Tx patients had the highest weight gains. Judged against international Tx patient data, the majority of our Swiss Tx recipients' experienced lower post-Tx weight gain. However, our findings show weight gain pattern differences, both within and across organ Tx groups that call for preventive measures.

    Information Communication Technology (ICT) has proven to be a strong public health tool. Keeping the future need of country and building National Disease Surveillance System, Integrated Disease Surveillance Project (IDSP) was launched by Hon'ble Union Minister of Health & Family Welfare in November 2004. It is a decentralized, State based surveillance program in the country. It is intended to detect early warning signals of impending outbreaks and help initiate an effective response in a timely manner. One of the major components of the project is the - use of Information Technology for collection, collation, compilation, analysis and dissemination of data besides distance education and video conferencing. A network of 800 sites across India has been established through Satellite, Broadband and High end Video conferencing equipments. The network is managed by a team of data managers and data entry operators at all state surveillance units and district surveillance units respectively. The network was proven to be extremely useful to respond to the current influenza A H1N1 pandemic. It is proposed to extend the network to cover private sector and provide convergence with other National Health Programs.

    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.

    This article reviews the situation of labor migrants from Kerala state, India, who were 40-60% of all contract workers in the Middle East and who returned after the mid-1980s. Descriptions are provided of the characteristics of return migrants, the Kerala economy, return migration policies, and impact studies of returnees. About 500,000 returned to Kerala. Returnees were middle aged, with low levels of education, skills, and experience. About 50% of returnees remained unemployed. The other 50% either retired or sought self-employment or other wage labor. Surveys conducted in 1985, 1987, 1993-93, and 1997 reveal that returnees peaked during the 1990s. By 1997, returnees to the Kadinamkulam panchayat included about one-sixth who were women. Most returnees had worked in Saudi Arabia, United Arab Emirates, and Kuwait. The reasons for return were poor working and living conditions, lack of opportunity or contract for staying longer, or forced repatriation. Upon return, 50% of the women and about 16% of the men remained unemployed. Return wages were about the same as before the migration. Returnees complained about the lack of support from government and society. Impact studies do not differentiate migration effects from development effects in general. Evaluation should focus on multidimensional impacts and individual attainment of emigration goals.

    Sexual behaviour studies are often challenged by sampling, participation and measurement biases, and may be unacceptable to participants. We invited 293 randomly selected female sex workers (FSWs) in Bangalore, India, to participate in a telephone survey, with condom breakage as the main outcome. Free cell phones were supplied and trained interviewers telephoned FSWs daily to ask about all sex acts the previous day. Later, we undertook focus groups to discuss the methodology with the participants. We evaluated technical and operational feasibility; data reliability and measurement error; emotional and fatigue effects; interviewer bias; survey reactivity effects; and user acceptability. Response rates were high, with 84% of invited participants complying fully with the protocol. The study ran smoothly, with little evidence of biases. The methodology was highly acceptable; the respondents enjoyed using a new telephone and being interviewed at times convenient to them. Other reasons for the success of the method were that the study was sanctioned and supported by the sex worker collective, and the interviewers were well trained and developed a strong rapport with the participants. The success of this methodology, and the wealth of data produced, indicates that it can be an important tool for conducting sexual behaviour research in low literacy, high sex volume populations.

    The biggest hurdle in renal transplantation is the ABO blood group system. But recently ABO incompatible renal transplants have been performed using plasmapheresis (PP) as a part of the preconditioning protocol. In the present study, the objective of PP along with immunosuppression was to bring down the antibody titer of the patient to ≤ 16 during the transplant and keep it low, around 32, until post-operative 4-14 weeks. The patient (O Negative) had his mother (B Positive) as the ABO non-identical donor. The PP was performed with an apheresis equipment Com.Tec (Fresenius Kabi, Germany) to lower the anti-B antibody titer in the recipient. An Antihuman globulin (AHG) titer was performed for anti-B antibody following the departmental standard operating procedure. A total of 11 plasmapheresis procedures was performed preoperatively and four procedures were performed post-operatively to maintain the titer of the anti-B antibody at or below the desired level. The baseline anti-B antibody titer in the recipient was 512. The baseline titer came down to 8 after the end of the 11th procedure. Post-operatively we performed four plasmapheresis procedures to keep the titer at 32. During the post-operative follow up the titer has been maintained at 32 and the serum creatinine level has been maintained at approximately 1.0mg/dl and other parameters relevant to graft function were within normal limits. Our case could be the first reported case from India in which we used a plasmapheresis procedure as a part of preconditioning protocol instead of using an immunoadsorption column. Furthermore, it could be one of the few ABOiRTx cases, which has been performed at an isoagglutinin titer of 512 using plasma exchange as part of a preconditioning regime.

    The diagnosis of coeliac disease has traditionally depended on symptoms and intestinal biopsies; nowadays, the diagnosis has been expanded to include an array of serological markers and subtle microscopic lesions. The most important advance in classifying mucosal lesions in coeliac disease was forwarded by Marsh (1992), who provided the biological explanation of how the small bowel reacts to a variety of environmental antigenic challenges including gluten. In the modified version of this classification (Arnhem 1998-1999) autoantibodies have integrated into Marsh's histopathological scheme. As a large part of the coeliac 'iceberg' remains unrecognised, the difficulties in diagnosis continue to challenge clinicians and researchers. Advances in immuno-histochemistry and discovery of the other sensitive markers have acquainted us with so-called Microscopic enteritis, the distinctive subtle abnormalities behind the atypical gluten sensitivity symptoms that often remain unrecognised. Current diagnostic pathways do not always include facilities for looking for this common histological feature in atypical cases. This is essential since improving of the detection rate has been shown to be directly proportional to recognition of cases with milder or minimal mucosal abnormalities. In this revision, we will define and characterise microscopic enteritis as the entity behind a wide range of unexplained gastrointestinal symptoms. Screening for this subtle and distinctive presentation in small bowel pathology will open a new prospect in recognising the most common but unrecognised atypical forms of symptomatic gluten related enteropathies.

    Several severe glaciations occurred during the Neoproterozoic eon, and especially near its end in the Cryogenian period (630-850 Ma). While the glacial periods themselves were probably related to the continental positions being appropriate for glaciation, the general coldness of the Neoproterozoic and Cryogenian as a whole lacks specific explanation. The Cryogenian was immediately followed by the Ediacaran biota and Cambrian Metazoan, thus understanding the climate-biosphere interactions around the Cryogenian period is central to understanding the development of complex multicellular life in general. Here we present a feedback mechanism between growth of eukaryotic algal phytoplankton and climate which explains how the Earth system gradually entered the Cryogenian icehouse from the warm Mesoproterozoic greenhouse. The more abrupt termination of the Cryogenian is explained by the increase in gaseous carbon release caused by the more complex planktonic and benthic foodwebs and enhanced by a diversification of metazoan zooplankton and benthic animals. The increased ecosystem complexity caused a decrease in organic carbon burial rate, breaking the algal-climatic feedback loop of the earlier Neoproterozoic eon. Prior to the Neoproterozoic eon, eukaryotic evolution took place in a slow timescale regulated by interior cooling of the Earth and solar brightening. Evolution could have proceeded faster had these geophysical processes been faster. Thus, complex life could theoretically also be found around stars that are more massive than the Sun and have main sequence life shorter than 10 Ga. We also suggest that snow and glaciers are, in a statistical sense, important markers for conditions that may possibly promote the development of complex life on extrasolar planets.

    Summary Background To evaluate the accuracy of high resolution ultrasound (USG) and MRI in the diagnosis of rotator cuff tears (RCT) and to determine if high resolution USG compares favorably in sensitivity and specificity to MRI in the diagnosis of rotator cuff injury. Material/Methods In this prospective comparative study, 40 patients with clinically suspected rotator cuff tears underwent both ultrasound and MRI of the shoulder. Out of these 40 patients, 31 patients who had positive findings for rotator cuff tears on ultrasound and/or MRI were finally included in the study while the remaining 9 patients with negative or unrelated findings were excluded. The USG and MRI were interpreted by two radiologists experienced in musculoskeletal radiology and blinded to findings of each other. Comparison was done using MRI as a standard reference. Results The agreement between USG and MRI for diagnosis of RCTs was statistically excellent; USG showed a sensitivity of 86.7% and a specificity of 100% for full-thickness tears, and a sensitivity of 89.7% and a specificity of 98.8% for partial-thickness tears; observed accuracy for full thickness tears was 98.4% and 95.9% for partial thickness tears. The Kappa coefficient of association was 0.91 for full thickness tears and 0.90 for partial thickness tears. Conclusions Considering the comparable diagnostic accuracy of USG and MRI, the former modality can be used as a first-line investigation for diagnosis of RCT. MRI should be used secondarily as a problem-solving tool either following an equivocal shoulder USG or for delineation of anatomy in cases where surgical correction is needed. PMID:27800039

Materials and Methods: Six secondary schools were randomly selected. The base-line Oral Hygiene Index simplified (OHI-S) and Plaque index (PI) scores for all the students were recorded. The teachers were trained on dental health facts. The six schools were divided into three groups of two schools with different intervention techniques: Group 1- Schools given no health education, Group 2 – Schools given health education by their school teachers on a fortnightly basis together with simple screening for deposits of gross calculus , Group 3 – Schools which were given health education by dental professionals at intervals of three months without any screening. Grade nine students were selected for pre and post intervention evaluation. The second examination was done six months following the intervention to find out the OHI-S and Plaque index scores. The examination was done by three trained and calibrated dentists. Data analysis was done with SPSS 16 with relevant statistical tests. Results: The mean OHI-S and PI scores were significantly less in group 2 and there was a statistically significant difference between the baseline OHI – S, PI score and the scores after six months in all the three groups. Conclusion: The concept of utilizing the teachers for frequent DHE and screening for any gross deposits of food debris and calculus is feasible. Also frequent DHE by teachers was more effective than the infrequent DHE by the professionals. PMID:23230385

    Contraceptive social marketing is a way of supplying contraceptives to consumers who cannot afford to buy them at full market price, yet are not reached by the free public distribution program. The process involves supplying a subsidized product through existing commercial distribution networks, using the mass media and other retail marketing techniques to commercially advertise the products. India was the first country to introduce this concept to its family planning program. India's social marketing program is also the largest in the world. Over the past 25 years, total condom sales in India have expanded under the program from less than 10 million per year to more than one billion. The authors present an overview of India's social marketing initiative, describe the firms participating in the program, and summarize the lessons learned from the social marketing experience. Problems and prospects, and experiences and implications are discussed.

    The Xiukang Mélange of the Yarlung-Zangbo suture zone in south Tibet documents low efficiency of accretion along the southern active margin of Asia during Cretaceous Neotethyan subduction, followed by final development during the early Paleogene stages of the India-Asia collision. Here we investigate four transverses in the Xigaze area (Jiding, Cuola Pass, Riwuqi and Saga), inquiry the composition in each transverse, and present integrated petrologic, U-Pb detrital-zircon geochronology and Hf isotope data on sandstone blocks. In fault contact with the Yarlung-Zangbo Ophiolite to the north and the Tethyan Himalaya to the south, the Xiukang mélange can be divided into three types: serpentinite-matrix mélange composed by broken Yarlung-Zangbo Ophiolite, thrust-sheets consisting mainly chert, quartzose or limestone sheets(>100m) with little intervening marix, and mudstone-matrix mélange displaying typical blocks-in-matrix texture. While serpentinite-matrix mélange is exposed adjacent to the ophiolite, distributions of thrust-sheets and blocks in mudstone-matrix mélange show along-strike diversities. For example, Jiding transverse is dominant by chert sheets and basalt blocks with scarcely sandstone blocks, while Cuola Pass and Saga transverses expose large amounts of limestone/quartzarenite sheets in the north and volcaniclastic blocks in the south. However, turbidite sheets and volcaniclastic blocks are outcropped in the north Riwuqi transverse with quartzarenite blocks preserved in the south. Three groups of sandstone blocks/sheets with different provenance and depositional setting are distinguished by their petrographic, geochronological and isotopic fingerprints. Sheets of turbiditic quartzarenite originally sourced from the Indian continent were deposited in pre-Cretaceous time on the northernmost edge of the Indian passive margin and eventually involved into the mélange at the early stage of the India-Asia collision. Two distinct groups of volcaniclastic

    In Bangladesh and the neighboring state of West Bengal, India, over 100 million people are affected by widespread arsenic poisoning through drinking water drawn from underground sources containing arsenic at concentrations well above the permissible limit of 50 μg/L. The health effects caused by arsenic poisoning in this area is as catastrophic as any other natural calamity that occurred throughout the world in recent times. Since 1997, over 200 community level arsenic removal units have been installed in Indian subcontinent through collaboration between Bengal Engineering and Science University (BESU), India and Lehigh University, USA. Approximately 200,000 villagers collect arsenic-safe potable water from these units on a daily basis. The treated water is also safe for drinking with regard to its total dissolved solids, hardness, iron and manganese content. The units use regenerable arsenic-selective adsorbents. Regular maintenance and upkeep of the units is administered by the villagers through formation of villagers' water committee. The villagers contribute towards the cost of operation through collection of a small water tariff. Upon exhaustion, the adsorbents are regenerated in a central facility by a few trained villagers. The process of regeneration reduces the volume of disposable arsenic-laden solids by nearly two orders of magnitude and allows for the reuse of the adsorbent material. Finally, the arsenic-laden solids are contained on well-aerated coarse sand filters with minimum arsenic leaching. This disposal technique is scientifically more appropriate than dumping arsenic-loaded adsorbents in the reducing environment of landfills as currently practiced in developed countries including the United States. The design of the units underwent several modifications over last ten years to enhance the efficiency in terms of arsenic removal, ease of maintenance and ecologically safe containment and disposal of treatment residuals.

    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.

  10. Paleocene-Eocene foreland basin evolution in the Himalaya of southern Tibet and Nepal: Implications for the age of initial India-Asia collision

    Siliciclastic sedimentary rocks derived from the southern Lhasa terrane, sitting depositionally upon rocks of the northern Indian passive continental margin, provide an estimate of the age of initial contact between the continental parts of the Indian and Asian plates. We report sedimentological, sedimentary petrological, and geochronological data from Upper Cretaceous-Paleocene strata in the Sangdanlin section, located along the southern flank of the Indus-Yarlung suture zone in southern Tibet. This is probably the most proximal, and therefore the oldest, record of the India-Asia collision. These strata were deposited by high-density turbidity currents (or concentrated density flows) and suspension settling of pelagic biogenic debris in a deep-marine setting. An abrupt change from quartz-arenitic to feldspatholithic sandstone compositions marks the transition from Indian to Asian sediment provenance. The abrupt compositional change is accompanied by changes in U-Pb ages of detrital zircons diagnostic of a sediment provenance reversal, from Indian to Asian sources. The timing of the transition is bracketed between ~60 Ma and 58.5 ± 0.6 Ma by detrital zircon U-Pb ages and zircon U-Pb ages from a tuffaceous bed in the upper part of the section. In the context of a palinspastically restored regional paleogeographic framework, data from the Sangdanlin section combined with previously published data from the northern Tethyan Himalaya and the frontal Nepalese Lesser Himalaya and Subhimalaya suggest that a flexural wave migrated ~1300 km southward across what is now the Himalayan thrust belt from Paleocene time to the present.

  11. Tectonothermal evolution of a garnet-bearing quartzofeldspathic gneiss from the Moyar shear zone, south India and its bearing on the Neoarchean accretionary tectonics

    We present mesoscale structural development across the Nilgiri Block and the flanking Moyar and Bhavani shear zones in south India, and detailed mineral-chemical and geothermobarometric studies of a garnet-bearing quartzofeldspathic gneiss from the easternmost part of the Moyar shear zone. Barring a narrow (< 100 μm) rim domain, major element distribution within garnet porphyroblasts reveals complete chemical homogenization. The absence of growth zoning in garnet porphyroblasts may suggest a protracted post-garnet growth residence period of the rock at elevated temperatures. Chemical zoning near garnet rim reflects the signature of both retrograde net-transfer (ReNTR) and retrograde exchange (ReER) equilibria. The ReNTR-equilibrium is recognized by prominent Mn kick-up in garnet, whereas the ReER-equilibrium is identified by divergence of Fe and Mg between garnet and biotite. Diffusion modelling, though qualitative, of the observed chemical zoning in garnet suggests an initial phase of rapid ( 150 °C/Ma) cooling, which may have been achieved by tectonic-extrusion-induced exhumation. Pressure-temperature conditions for peak, ReNTR and ReER are constrained, respectively, at 900 °C; 9-11 kbar, 735 °C; 8 kbar and 685 °C; 7.8 kbar. Analyses of structural fabrics establish oppositely verging nature of the Moyar and Bhavani shear zone and may suggest a doubly vergent orogenic development, with the former as prowedge and the latter as retrowedge. The presence of the Nilgiri Block as a topographically elevated region between these oppositely dipping thrust faults indeed corroborates a doubly vergent orogenic setup. The tectonic scenario is comparable with a continent-continent collision type accretionary tectonics. Peak high-P granulite facies metamorphism and post-peak long residence period of the studied quartzofeldspathic gneiss at deep crustal level suitably fit into the Neoarchean crustal dynamics resulting in crustal thickening, in the order of 41 km, within the

    Over the past century, numerous vertebrate fossils collected near the town of Ramnagar, India, have proven to be important for understanding the evolution and biogeography of many mammalian groups. Primates from Ramnagar, though rare, include a number of hominoid specimens attributable to Sivapithecus, as well as a single published mandibular fragment preserving the P4-M1 of the Miocene adapoid Sivaladapis palaeindicus. Since 2010, we have renewed fossil prospecting in the Lower Siwalik deposits near Ramnagar in an attempt to better understand the evolution, biogeographic timing, and paleoclimatic context of mammalian radiations in Asia, with a particular focus on primates. Our explorations have resulted in the identification of new fossil localities, including the site of Sunetar. The age of Sunetar and the Ramnagar region, in general, is tentatively dated between 14 and 11 Ma. In 2014, a partial right mandible of a sivaladapid primate was recovered at Sunetar, preserving the corpus with P4 roots and worn M1-M3 dentition. Although sivaladapids are known by numerous specimens of two genera (Sivaladapis and Indraloris) at Lower Siwalik sites on the Potwar Plateau (Pakistan) and at the Middle Siwalik locality of Haritalyangar (India), this new specimen is just the second sivaladapid recovered from the Ramnagar region. Our analyses suggest that the new specimen is distinct from all other sivaladapids, and we therefore describe it as a new genus and species close to the base of the Sivaladapinae.

    The Closepet granite (CPG), a spectacularly exposed magmatic body along with other intrusive bodies (to the east of it) typifies the late Archean granitic activity in the Eastern Dharwar Craton (EDC), south India. In the present study, the P-T-fO2 conditions of emplacement and physico-chemical environment of the associated magmatic-hydrothermal regime of CPG have been retrieved on the basis of mineral chemical and fluid inclusion studies. Amphibole-plagioclase Ti-in-amphibole and Ti-in-biotite geothermometers along with Al-in-amphibole geobarometer have been used to reconstruct the emplacement temperature and pressure conditions in the majority of the pluton. Estimated temperatures of emplacement of CPG vary from to 740 to 540 °C. A variation of pressure from 4.8 to 4.1 kilo bars corresponding to this temperature range was obtained. While there is a faint south to north negative gradient in temperature, the variation of pressure does not seem to follow this trend and indicates more or less same crustal level of emplacement for the body between Ramanagaram-Kalyandurga segment extending for about 230 km. Mineral chemistry of biotite indicates crystallization of CPG under high oxygen fugacity conditions (mostly above QFM buffer) with no clear spatial variation in the fugacity of halogen species in the late-stage magmatic fluid. It may be surmised that barring the southernmost part of CPG, there is no perceptible variation in the physicochemical environment of emplacement. Fluid Inclusion studies in the granitic matrix quartz and pegmatite/vein quartz show dominance of H2O and H2O-CO2 fluids respectively in them. The difference in the fluid characteristics is interpreted in terms of the initial loss of CO2 rich fluid from granitic magma and aqueous-rich nature during the later stages of crystallization of quartz. The exsolved CO2-rich fluid was responsible in formation of the later quartz and pegmatitic veins at different crustal levels and also possibly was

    The Dizo Valley is an important geological province in NW Karbi Hills of Shillong Plateau (NE India). The Karbi Hills contain profusely intruded bodies of A-type granitoids that have been attributed to a post-collision setting. The Dizo Valley magmatic suite is a bimodal association of voluminous granitoid plutons with dolerite and amphibolites (metabasalts). Our present data demonstrates that there were two episodes of A-type granitoid magmatism in this part of the craton. Studied Kathalguri granitoids (KG) of Dizo Valley represents the late phase, about 515.1 ± 3.3-515.5 + 2.7 Ma age, dated by zircon LA-ICPMS U-Pb method. The age of emplacement represent the late Pan-African (Mid-Cambrian) event of granitoid magmatism concomitant to the Gondwana continental restructuring event with the integration of East and West Gondwana held between 570 and 510 Ma. A previous granitoid emplacement episode of about 690 Ma has been referred in literature. The late phase of granitoids formation tends to be massive, occasionally show flow banding, degassing pots and amphibolite breccias with chilled margin. Its mineralogy shows abundance of accessory phases like zircon, allanite, apatite, bastnaesite, monazite, sphene and xenotime. Geochemical parameters offer metaluminous to peraluminous, non-porphyritic, shoshonitic to high potassium, calc-alkaline composition. Other chemical criteria bear the character of A2-type granitoids with high SiO2 (64.00-70.75 wt.%) and alkali (3.26-6.30 wt.%) but poor Ca and Mg content. The binary plots of Y + Nb-Rb and Y-Nb confirm their within-plate granite (WPG) character. The pluton is enriched in total REE (av. 614.64 ppm), Y and heavy REE (27.62-65.00 ppm; av. 41.87 ppm) compared to low calcium granite; Eu anomaly is moderately negative (∂Eu = 0.43). Enrichment of incompatible elements like large ion lithophile elements (LILE) of Rb, Ba and Sr and REE are consistent with the A-type granites. The behavior of Ba, Rb and Sr suggest a progressive

    The Neoarchean Gadwal greenstone belt in the eastern Dharwar craton, India, hosts a well preserved metavolcanic sequence that is dominated by tholeiitic and calc-alkaline basalt-andesite-dacite-rhyolite series, which includes boninitic geochemical varieties. Bulk-rock Lu-Hf and Sm-Nd isotope systematics of these apparently arc-related volcanic rocks yield indistinguishable ages of 2.701 ± 0.024 Ga and 2.702 ± 0.026 Ga, respectively. On the basis of the close spatial association and identical ages of the different rock types we suggest 2.70 ± 0.03 Ga as the age of crystallization of the different rock types within the Gadwal metavolcanic sequence. In contrast, bulk-rock Pb-Pb isotope systematics of the same samples yield a significantly younger and less precise age of 2.466 Ga (+0.068/-0.110 Ga). We tentatively interpret this younger age to represent a metallogenic and crustal reworking event in the Dharwar craton, which disturbed the U-Pb system but not the Lu-Hf or Sm-Nd systems. The Gadwal metavolcanic rocks have positive initial ɛHf(2.70Ga) = + 1.6 to + 8.7 and slightly negative to positive ɛNd(2.70Ga) = -0.1 to + 3.0 values, consistent with an origin from a long term depleted source relative to a chondritic reservoir at ˜2.7 Ga. Lack of correlation between initial isotopic compositions and major or trace element indices of fractionation and alteration suggest that the observed isotope variability probably reflects compositional variation in the Gadwal source, similar to that observed in modern day island arcs. Two boninitic samples of the Gadwal sequence have ɛHf ˜ 8.3 and 8.7, and are more radiogenic than average depleted mantle for the time period 3.2 to 2.5 Ga (ɛHf = 4 to 6). Early (perhaps Hadean) differentiation events that led to a depleted and heterogeneous mantle are apparent in the Nd and Hf isotope systematics of 3.7-3.8 Ga Isua supracrustal rocks.

    Background: This 26-week, open-label observational study assessed the incidence and type of adverse events (AEs) associated with liraglutide use according to the standard clinical practice settings and the local label in India. Materials and Methods: A total of 1416 adults with type 2 diabetes (T2D) treated with liraglutide in 125 sites across India were included in the study. Participants were newly diagnosed or already receiving antidiabetic medications. Safety and efficacy data were collected at baseline and at approximately weeks 13 and 26. The primary outcome was incidence and type of AEs while using liraglutide, with events classified by Medical Dictionary for Regulatory Activities system organ class and preferred term. The secondary objective was to assess other clinical parameters related to effective T2D management. Results: Twenty AEs, predominately gastrointestinal, were reported in 1.3% of the study population in scheduled visits up to week 26. No serious AEs, including death, were reported. Hypoglycemic episodes were reported in 7.3% of participants at baseline and 0.7% at week 26. No major hypoglycemic events were reported up to week 26 (baseline: 0.4%). Glycated hemoglobin was reduced from baseline (8.8 ± 1.3%) to week 26 by 1.6 ± 1.1% (P < 0.0001); significant improvements in fasting blood glucose, and 2-h postprandial blood glucose (post-breakfast, -lunch, and -dinner) were also observed. Mean body weight decreased by 8.1 ± 6.5 kg from baseline (92.5 ± 14.6 kg; P < 0.0001). Conclusions: From the number of AEs reported, it is suggested that liraglutide was well tolerated in subjects with T2D treated under standard clinical practice conditions in India. Liraglutide was effective, and no new safety concerns were identified. PMID:27867889

We propose that the conspicuous buoyant central part of the Gop Rift is likely associated with a continental C-Block as described in a recent paper on conjugated VPMs8, at least in the southern part of the Gop Rift. The crust below the Laxmi basin is probably transitional continental i.e. strongly intruded. West of India and west of the Laxmi Ridge, the transition to the Carlsberg Basin occurs along a clearly-expressed transform fault, not through an extended and thinned continental margin. We reinterpret the whole system based on those observations and propositions, giving some explanations on controversial magnetic anomalies based on similar observations from the southern Atlantic Ocean. 1: Collier et al., 2008.

    NASA Astrophysics Data System (ADS)

    Bhattacharyya, Kathakali

    a total minimum shortening of ˜502 km (˜82%) south of the South Tibetan Detachment system (STDS). Based on this shortening, the average long-term shortening rate is estimated to be ˜22mm/yr in this region. The available shortening estimates from different parts of the Himalayan arc show significant variations in shortening, but based on the present available data, it is difficult to evaluate the primary cause for this variation. The shortening in the Himalayan fold-thrust belt (FTB) is highest in the middle of the Himalayan arc (western Nepal) and progressively decreases towards the two syntaxes. Although the width of the Lesser Himalayan belt decreases in the eastern Himalaya, the Lesser Himalayan shortening percentage remains approximately similar to that in the Nepal Himalaya. In addition, the shortening accommodated within the Lesser Himalayan duplex progressively increases from the western to the eastern Himalaya where it accommodates nearly half of the total shortening. The regional restorations suggest that the width of the original Lesser Himalayan basin may have played an important role in partitioning the shortening in the Himalayan FTB. In addition, the retrodeformed cross section in the Darjeeling-Sikkim Himalaya provides insights into the palinspastic reconstruction of the Gondwana basin of Peninsular India, suggesting that this basin extended ˜150 km northward of its present northernmost exposure in this region. The balanced cross section suggests that each of the MCT sheets has undergone translation of ≥100km in this region. Although a regional scale flat-on-flat relationship is seen in the MCT sheets, there is a significant variation in overburden from the trailing portion to the leading edge of the MCT due to the geometry of the tapered crystalline orogenic wedge. Microstructural studies from three segments of the MCT2 fault zone suggest that the MCT2 zone has undergone strain softening by different mechanisms along different portions of its

    The Kerala Khondalite Belt (KKB) constitutes an important lower crustal segment in the southern Indian granulite terrain. Dominant rock types, except sillimanite bearing gneisses, are classified as sodic and potassic granitoids and a general supracrustal origin is ascribed to these rocks. We present here new results from our studies on mineral and whole rock major- and trace-element and REE systematic of major litho units of the belt. We address the petrogenesis, physical conditions during crystallization and tectonic setting of KKB rocks. Granitoids (gneiss and variants of charnockites) makeup more than 70% of exposed rock types in KKB. They are classified as sodic and potassic groups based on K2O/Na2O ratios. Mineral chemical analysis of granitoids, especially biotites from different groups document igneous parentage and as potential indicator of nature of the magma. Biotites from sodic group are Mg2+-rich (XMg:0.47-0.63), denote calc-alkaline host in contrast to those from potassic groups, which are Fe2+-types with much lower XMg (0.37-0.44) and suggest an alkaline host. Biotites in potassic group are poorer in A12O3 than sodic, indicating evolved nature of the magmatic protolith. Decrease in ΣAl with increasing Fe/(Fe+Mg) values of biotites indicate progressive oxidising condition during magma evolution. Compositional variation of biotite allow us to speculate that the host magmas of sodic charnockites as calc-alkaline, arc-type with features typical of Archaean TTGs and potassic groups as partial melts of meta-igneous lower crust with little mantle contribution. The sodic group has geochemical affinity to Archaean tonalities with low-K, calc-alkaline, metaluminous to peraluminous chemistry. Compositionally contrasting K-rich rocks are essentially of granitic composition. Most oxides in both the groups, with exceptions of K2O and Na2O, show negative correlation with SiO2. The sodic group is enriched in Sr and depleted in Rb and Th. They exhibit geochemical

  1. Active tectonic influence on the evolution of drainage and landscape: Geomorphic signatures from frontal and hinterland areas along the Northwestern Himalaya, India

    The Kangra Re-entrant in the NW Himalaya is one of the most seismically active regions, falling into Seismic Zone V along the Himalaya. In 1905 the area experienced one of the great Himalayan earthquakes with magnitude 7.8. The frontal fault system - the Himalayan Frontal Thrust (HFT) associated with the foreland fold - Janauri Anticline, along with other major as well as secondary hinterland thrust faults, provides an ideal site to study the ongoing tectonic activity which has influenced the evolution of drainage and landscape in the region. The present study suggests that the flat-uplifted surface in the central portion of the Janauri Anticline represents the paleo-exit of the Sutlej River. It is suggested that initially when the tectonic activity propagated southward along the HFT the Janauri Anticline grew along two separate fault segments (north and south faults), the gap between these two fault and the related folds allowed the Sutlej River to flow across this area. Later, the radial propagation of the faults towards each other resulted in an interaction of the fault tips, which caused the rapid uplift of the area. Rapid uplift resulted in the disruption and longitudinal deflection of the Sutlej river channel. Fluvial deposits on the flat surface suggest that an earlier fluvial system flowed across this area in the recent past. Geomorphic signatures, like the sharp mountain fronts along the HFT in some places, as well as along various hinterland subordinate faults like the Nalagarh Thrust (NaT), the Barsar Thrust (BaT) and the Jawalamukhi Thrust (JMT); the change in the channel pattern, marked by a tight incised meander of the Beas channel upstream of the JMT indicate active tectonic movements in the area. The prominent V-shaped valleys of the Beas and Sutlej rivers, flowing across the thrust fronts, with Vf values ranging from <1.0-1.5 are also suggestive of ongoing tectonic activity along major and hinterland faults. This suggests that not only is the HFT

  3. C, O, Sr and Nd isotope systematics of carbonates of Papaghni sub-basin, Andhra Pradesh, India: Implications for genesis of carbonate-hosted stratiform uranium mineralisation and geodynamic evolution of the Cuddapah basin

    The Cuddapah basin (CB) is one of a series of Proterozoic basins that overlie the Archaean cratons of India, and contains a unique stratiform carbonate-hosted uranium mineralisation. In the present work, we discuss stable (C, O) and radiogenic (Nd, Sr) isotope systematics of carbonates of the Papaghni sub-basin in order to understand uranium ore forming processes and geodynamic evolution of the CB. Uranium mineralised dolomites (UMDs) of the basal Vempalle Formation show a significantly lighter (~ 1.5‰) C-isotope signature compared to that of open-marine stromatolitic sub-tidal facies, suggesting input of isotopically lighter carbon through in situ remineralisation of organic matter (OM). This implies deposition in a hydrologically-restricted, redox-stratified lagoonal basin wherein exchange with open oceanic dissolved inorganic carbon (DIC) was limited. Persistent bottom water anoxia was created and maintained through consumption of dissolved oxygen (DO) by decaying OM produced in oxidised surface water zone. Significantly more radiogenic εNd(t) of UMD (- 6.31 ± 0.54) compared to that of Dharwar upper crust (- 8.64 ± 3.11) indicates that dissolved constituents did not originate from the Dharwar craton, rather were derived from more juvenile exotic sources - possibly from a continental arc. Dissolved uranyl ions (U+ 6) were introduced to the basin through fluvial run-off and were reduced to immobile uranous ions (U+ 4) at the redox interface resulting in precipitation of pitchblende and coffinite. Carbonate horizons of upper Vempalle Formation and Tadpatri Formation show progressively more radiogenic Nd isotope compositions signifying increased juvenile arc contribution to the Papaghni sub-basin through time, which is also corroborated by the presence of younger zircons (1923 ± 22 Ma) in Pulivendla quartzites. We propose that the Papaghni sub-basin opened as a back-arc extensional basin at ~ 2 Ga as a result of westerly-directed subduction of oceanic crust

    To assess the clinical, radiological and functional evolution of osteosynthesis using a cephalomedullary nail, in unstable trochanteric fractures of the femur, over a one-year postoperative follow-up. Methods: Fourteen men and 23 women of mean age 77.7 years were evaluated. Twenty-seven of them had fractures classified as AO/ASIF 31A2 and ten as 31A3. The patients were evaluated clinically, radiologically and functionally one week, two weeks, one month, two months, six months and one year after the operation. Results: The clinical complications comprised five cases of death, one case of calcaneal ulcer, one case of acute arterial obstruction and two cases of deep vein thrombosis. The radiographic evaluation showed that the mean cervicodiaphyseal angle in the immediate postoperative period was 132.5°. The mean tip-apex index was 22.8 mm. After one year, the mean cervicodiaphyseal angle was 131.7°. Fracture consolidation was seen in all the patients six months after the operation, except in one case that presented cut-out. There were no cases of fracture below the implant. The functional evaluation using the Harris score after one year showed a mean of 69.3 points. The evaluation of walking progress showed that after one year, 40.6% of the patients had the same ability to walk that they had before the fracture. The visual analogue pain scale showed that a significant decrease in pain complaints occurred, going from 5.19 in the first week to 2.25 after 1 year. Conclusion: Osteosynthesis using a cephalomedullary nail resulted in low rates of clinical and mechanical complications and adequate functional outcomes. PMID:27027025

    The outbreak of highly pathogenic avian influenza (HPAI) H5N1 disease has led to significant loss of poultry and wild life and case fatality rates in humans of 60%. Wild birds are natural hosts for all avian influenza virus subtypes and over120 bird species have been reported with evidence of H5N1 infection. Influenza A viruses possess a segmented RNA genome and are characterized by frequently occurring genetic reassortment events, which play a very important role in virus evolution and the spread of novel gene constellations in immunologically naïve human and animal populations. Phylogenetic analysis of whole genome or sub-genomic sequences is a standard means for delineating genetic variation, novel reassortment events, and surveillance to trace the global transmission pathways. In this paper, special emphasis is given to the transmission and circulation of H5N1 among wild life populations, and to the reassortment events that are associated with inter-host transmission of the H5N1 viruses when they infect different hosts, such as birds, pigs and humans. In addition, we review the inter-subtype reassortment of the viral segments encoding inner proteins between the H5N1 viruses and viruses of other subtypes, such as H9N2 and H6N1. Finally, we highlight the usefulness of genomic sequences in molecular epidemiological analysis of HPAI H5N1 and the technical limitations in existing analytical methods that hinder them from playing a greater role in virological research.

    PubMed Central

    2014-01-01

    Background Parkinson’s disease affects facial, vocal and trunk muscles. As symptoms progress, facial expression becomes masked, limiting the person’s ability to communicate emotions and intentions to others. As people with the disease live and reside in their homes longer, the burden of caregiving is unmitigated by social and emotional rewards provided by an expressive individual. Little is known about how adults living with Parkinson’s disease manage their social lives and how an inability to be emotionally expressive can affect social connections and health. Because social networks have been shown to be crucial to the overall well-being of people living with chronic diseases, research is needed on how expressive capacity affects life trajectories and health. Methods/Design The overall objective is to understand the emergence and evolution of the trajectories of the self-management of the social lives of people living with Parkinson’s disease. The central hypothesis is that expressive capacity predicts systematic change in the pattern of social self-management and quality of life outcomes. The specific aims of this 3-year longitudinal study of 120 people with the disease and a maximum of 120 care partners are: 1) characterize social self-management trajectories over a 3-year period; 2) estimate the degree to which expressive nonverbal capacity predicts the trajectory; and 3) determine the moderating effect of gender on the association between expressive capacity and change in social self-management. Each participant will be assessed 14 times to detect rapid and non-linear changes in social participation and management of social activities; social network; and social comfort, general health and well-being. Discussion This project will provide evidence to guide the development of interventions for supporting social integration of those living with Parkinson’s disease, thus leading to improved overall health. It focuses on the novel construct of social self

However, behavior only approaches these limits after a long period of learning while the cerebral cortex interacts with the basal ganglia, an ancient part of the vertebrate brain that is responsible for learning sequences of actions directed toward achieving goals. Progress has been made in understanding the algorithms used by the brain during reinforcement learning, which is an online approximation of dynamic programming. Humans also make plans that depend on past experience by simulating different scenarios, which is called prospective optimization. The same brain structures in the cortex and basal ganglia that are active online during optimal behavior are also active offline during prospective optimization. The emergence of general principles and algorithms for goal-directed behavior has consequences for the development of autonomous devices in engineering applications.

    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.

    The remote estimation of leaf biochemical content from spaceborne platforms has been the subject of many studies aimed at better understanding of terrestrial ecosystem functioning. The major ecological processes involved in exchange of matter and energy, like photosynthesis, primary production, evaportranspiration, respiration, and decomposition can be related to plant properties e.g., chlorophyll, water, protein, cellulose and lignin contents. As leaves represent the most important plant surfaces interacting with solar energy, a top priority has been to relate optical properties to biochemical constituents. Two different approaches have been considered: first, statistical correlations between the leaf reflectance (or transmittance) and biochemical content, and second, physically based models of leaf scattering and absorption developed using the laws of optics. Recently reviewed by Verdebout et al., the development of models of leaf optical properties has resulted in better understanding of the interaction of light with plant leaves. Present radiative transfer models mainly use chlorophyll and/or water contents as input parameters to calculate leaf reflectance. Inversion of these models allows to retrieve these constituents from spectrophotometric measurements. Conel et al. recently proposed a two-stream Kubelka-Munk model to analyze the influence of protein, cellulose, lignin, and starch on leaf reflectance, but in fact, the estimation of leaf biochemistry from remote sensing is still an open question. In order to clarify it, a laboratory experiment associating visible/infrared spectra of plan leaves both with physical measurements and biochemical analyses was conducted at the Joint Research Center during the summer of 1993. This unique data set has been used to upgrade the PROSPECT model, by including leaf biochemistry.

  17. 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

    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.

    Throughout the Himalayan thrust belt, klippen of questionable tectonostratigraphic affinity occur atop Lesser Himalayan rocks. Integrated U-Pb ages, Hf isotopic, and whole rock trace element data establish that the Askot klippe, in northwest India, is composed of Paleoproterozoic lower Lesser Himalayan rocks, not Greater Himalayan rocks, as previously interpreted. The Askot klippe consists of 1857 ± 19 Ma granite-granodiorite gneiss, coeval 1878 ± 19 Ma felsic volcanic rock, and circa 1800 Ma Berinag quartzite, representing a small vestige of a Paleoproterozoic (circa 1850 Ma) continental arc, formed on northern margin of the north Indian cratonic block. Detrital zircon from Berinag quartzite shows ɛHf1850 Ma values between -9.6 and -1.1 (an average of -4.5) and overlaps with ɛHf1850 Ma values of the Askot klippe granite-granodiorite gneiss (-5.5 to -1.2, with an average of -2.7) and other Paleoproterozoic arc-related Lesser Himalayan granite gneisses ( -4.8 to -2.2, with an average of -4.0). These overlapping data suggest a proximal arc source for the metasedimentary rocks. Subchondritic ɛHf1850 Ma values (-5.5 to -1.2) of granite-granodiorite gneiss indicate existence of a preexisting older crust that underwent crustal reworking at circa 1850 Ma. A wide range of ɛHf1850 Ma values in detrital zircon (-15.0 to -1.1) suggests that a heterogeneous crustal source supplied detritus to the northern margin of India. These data, as well as the presence of a volcanogenic massive sulphide deposit within the Askot klippe, are consistent with a circa 1800 Ma intra-arc extensional environment.

    The Shillong Plateau is a unique basement-cored uplift in the foreland of the eastern Himalaya that accommodates part of the India-Eurasia convergence since the late Miocene. It was uplifted in the late Pliocene to 1600 m, potentially inducing regional climatic perturbations by orographically condensing part of the Indian Summer Monsoon (ISM) precipitations along its southern flank. As such, the eastern Himalaya-Shillong Plateau-ISM is suited to investigate effects of tectonics, climate, and erosion in a mountain range-broken foreland system. This study focuses on a 2200 m thick sedimentary section of the Siwalik Group strategically located in the lee of the Shillong Plateau along the Dungsam Chu at the front of the eastern Bhutan Himalaya. We have performed magnetostratigraphy constrained by vitrinite reflectance and detrital apatite fission track dating, combined with sedimentological and palynological analyses. We show that (1) the section was deposited between 7 and 1 Ma in a marginal marine deltaic transitioning into continental environment after 5 Ma, (2) depositional environments and paleoclimate were humid with no major change during the depositional period indicating that the orographic effect of the Shillong Plateau had an unexpected limited impact on the paleoclimate of the Bhutanese foothills, and (3) the diminution of the flexural subsidence in the basin and/or of the detrital input from the range is attributable to a slowdown of the displacement rates along the Main Boundary Thrust in eastern Bhutan during the latest Miocene-Pleistocene, in response to increasing partitioning of the India-Eurasia convergence into the active faults bounding the Shillong Plateau.

    Housing cooperatives became active in urban areas in Sweden, India and the United States during the interwar period. Yet, after the second world war, while housing cooperatives grew phenomenally nationwide in Sweden and India, they did not do so in the United States. This article makes a comparative institutional analysis of the evolution of housing cooperatives in these three countries. The analysis reveals that housing cooperatives' relationship with the state and the consequent support structures explain the divergent evolution. Although the relationships between cooperatives and the state evolved over time, they can be characterized as embedded autonomy, overembeddedness and disembeddedness in Sweden, India and the United States respectively. Whereas the consequent support structures for housing cooperatives became well developed in Sweden and India, such structures have been weak in the United States. The article highlights the need for embedded autonomy and the need for supportive structures to enable the growth of housing cooperatives.

    After the successful operation at the centre-of-mass energies of 7 and 8 TeV in 2010-2012, the LHC was ramped up and successfully took data at the centre-of-mass energies of 13 TeV in 2015 and 2016. Meanwhile, plans are actively advancing for a series of upgrades of the accelerator, culminating roughly ten years from now in the high-luminosity LHC (HL-LHC) project, which will deliver of the order of five times the LHC nominal instantaneous luminosity along with luminosity levelling. The ultimate goal is to extend the dataset from about few hundred fb ‑1 expected for LHC running by the end of 2018 to 3000 fb ‑1 by around 2035 for ATLAS and CMS. The challenge of coping with the HL-LHC instantaneous and integrated luminosity, along with the associated radiation levels, requires further major changes to the ATLAS detector. The designs are developing rapidly for a new all-silicon tracker, significant upgrades of the calorimeter and muon systems, as well as improved triggers and data acquisition. ATLAS is also examining potential benefits of extensions to larger pseudorapidity, particularly in tracking and muon systems. This report summarizes various improvements to the ATLAS detector required to cope with the anticipated evolution of the LHC luminosity during this decade and the next. A brief overview is also given on physics prospects with a pp centre-of-mass energy of 14 TeV.

    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.

    Floods devestated parts of eastern India along the Brahmaputra River in June 2000. In some tributaries of the Brahmaputra, the water reached more than 5 meters (16.5 feet) above flood stage. At least 40 residents died, and the flood waters destroyed a bridge linking the region to the rest of India. High water also threatened endangered Rhinos in Kaziranga National Park. Flooded areas are shown in red in the above image. The map was derived from Advanced Very High Resolution Radiometer (AVHRR) data taken on June 15, 2000.

    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.

  2. The occurrence of fluor-wagnerite in UHT granulites and its implications towards understanding fluid regimes in the evolution of deep crust: a case study from the Eastern Ghats Belt, India

    2016-09-01

    We report the occurrence of a rare phosphate mineral, fluor-wagnerite (Mg1.91-1.94Fe0.06-0.07Ca<0.01) (P0.99-1.00O4)(OH0.02-0.17F0.98-0.83) from the Eastern Ghats Belt of India, an orogenic belt evolved during Meso- to Neoproterozoic time. The host rock, i.e. high- to ultrahigh temperature (UHT) granulites (~1000 °C, 8-9 kbar) of the studied area was retrogressed after emplacement to mid-crustal level (800-850 °C, 6-6.5 kbar) as deduced from their pressure-temperature histories. Based on mineral chemical data and micro-Raman analyses, we document an unusual high Mg-F-rich chemistry of the F-wagnerite, which occur both in peak metamorphic porphyroblastic assemblages as well as in the retrograde matrix assemblage. Therefore, in absence of other common phosphates like apatite, fluor-wagnerite can act as an indicator for the presence of F-bearing fluids for rocks with high X Mg and/or fO2. The occurrence of F-rich minerals as monitors for fluid compositions has important implications for the onset of biotite dehydration melting and hence melt production in the deep crust. We propose that fluor-wagnerite can occur as an accessory mineral associated with F-rich fluids in lower-mid crustal rocks, and F in coexisting minerals should be taken into consideration when reconciling the petrogenetic grid of biotite-dehydration melting.

    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.

    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

    2013-11-01

    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.

    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.

  11. Psychophysiology of prospective memory.

    PubMed

    Rothen, Nicolas; Meier, Beat

    2014-01-01

    Prospective memory involves the self-initiated retrieval of an intention upon an appropriate retrieval cue. Cue identification can be considered as an orienting reaction and may thus trigger a psychophysiological response. Here we present two experiments in which skin conductance responses (SCRs) elicited by prospective memory cues were compared to SCRs elicited by aversive stimuli to test whether a single prospective memory cue triggers a similar SCR as an aversive stimulus. In Experiment 2 we also assessed whether cue specificity had a differential influence on prospective memory performance and on SCRs. We found that detecting a single prospective memory cue is as likely to elicit a SCR as an aversive stimulus. Missed prospective memory cues also elicited SCRs. On a behavioural level, specific intentions led to better prospective memory performance. However, on a psychophysiological level specificity had no influence. More generally, the results indicate reliable SCRs for prospective memory cues and point to psychophysiological measures as valuable approach, which offers a new way to study one-off prospective memory tasks. Moreover, the findings are consistent with a theory that posits multiple prospective memory retrieval stages.

    2009-03-01

    Migmatites from Cone Peak, California, USA and the Satnur-Sangam road, Southern Karnataka, India contain coarser grained orthopyroxene-bearing leucosomes with subordinate biotite in finer grained hornblende-biotite-pyroxene-bearing hosts. At both localities the leucosomes are enriched in quartz and feldspar and have a higher ratio of pyroxene to hornblende + biotite compared to the host rocks. Biotite grains in leucosomes along the Satnur-Sangam road are concentrated at the margins of orthopyroxene grains and have lower abundances of Ti, Fe, and Cl and a higher abundance of F than biotite grains from the host rock. Fluorapatite grains in all rocks from both localities contain monazite inclusions similar to those produced experimentally by metasomatically induced dissolution and reprecipitation. Some fluorapatite grains at both localities are partially rimmed by allanite. The only compositional differences found between fluorapatite grains in the leucosomes and host rocks were higher concentrations of Cl in grains in leucosomes from Cone Peak. The mineralogies of the rocks suggest that the leucosomes formed by dehydration melting reactions that consumed feldspar, quartz, hornblende, and biotite and produced orthopyroxene. Allanite rims at the margins of fluorapatite grains may have formed by the later retrogression of monazite rims formed by incongruent dissolution of fluorapatite in the melt. Biotite grains at the margins of orthopyroxene crystals in the leucosomes from the Satnur-Sangam road apparently formed by retrogression of orthopyroxene upon the solidification of the anatectic melt. A similar high-grade retrogression did not affect orthopyroxene crystals at Cone Peak, indicating that H2O was removed from the crystallizing leucosomes probably in a low H2O activity fluid. Compositional differences between the paleosome and neosomes at Cone Peak are best explained by metasomatic interaction with concentrated brines while elevated Cl concentrations in

    2012-12-01

    Nuggihalli greenstone belt is one of the oldest greenstone belts (3.4-3.0 Ga) in the Western Dharwar craton, southern India. It consists of conformable metavolcanic (e.g., komatiite and komatiitic basalt) and metasedimentary rocks belonging to the Sargur Group. Sill-like ultramafic-mafic plutonic bodies are present within these schistose rocks which are in turn enclosed by tonalite-trondhjemite-granodiorite gneisses (TTG). The plutonic suite occurs as a layered succession of serpentinite (after dunite) and tremolite-chlorite-actinolite schist (after peridotite) hosting chromitite bodies, anorthosite, pyroxenite, and gabbro hosting magnetite bands. Whole-rock Sm-Nd data for the peridotite-anorthosite-pyroxenite-gabbro unit yield a correlation line with a slope corresponding to an age of 3125 ± 120 Ma (MSWD = 1.3) which is similar to ages of komatiitic rocks of the older greenstone belts in the craton. A whole rock Pb-Pb errorchron age of 2801 ± 110 Ma (MSWD = 102) has been obtained for the entire plutonic ultramafic-mafic suite; this represents (partial) redistribution/resetting of the U-Pb system during a younger metamorphic event and by the magmatic activity during formation of the younger greenstone belts. The positive ɛNd values (+ 1.7 to + 3.4) of the ultramafic-mafic rocks, and low initial 87Sr/86Sr values (at 3.1 Ga) of the gabbros (0.70097-0.70111) implies derivation of the parental magma from a depleted mantle source. The REE pattern of the metavolcanic schists bears resemblance with the pattern of Al-depleted komatiites. Major and trace element variation in the schists correspond with the fractionation trend exhibited by komatiites to komatiitic basalts in the older greenstone belts within the craton. Coherent patterns of whole-rock major and trace element data, along with the layered nature of the sill-like ultramafic-mafic rocks indicate that the plutonic and volcanic suites are related by analogous fractional crystallization processes.

    Today, community pharmacists play an important role in any country as they take responsibility for patient’s medicine related needs for access to healthcare. However, in India only the supply of medicines remains the core activity of the community pharmacist. Most community pharmacists in the country still hardly offer patient‐oriented service. The role of the pharmacists in the community, and with it their medicine management, may change in the wake of the rapid growth of domestic medicine output and national healthcare expenditure. This article seeks to discuss the genesis of Indian community pharmacy, the majority of which are privately owned, and sketches its education, training and future prospects. PMID:23093872

  3. Astronomical Instruments in India

    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.

    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.

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.

  8. Protein intakes in India.

    PubMed

    Swaminathan, Sumathi; Vaz, Mario; Kurpad, Anura V

    2012-08-01

    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.

    India has a high potential for solar energy applications due to its geographic position within the Sun Belt and the large number of cloudless days in many regions of the country. However, certain regions of India, particularly those largely populated, can exhibit large aerosol loading in the atmosphere as a consequence of anthropogenic emissions that could have a negative feedback in the solar resource potential. This effect, named as solar dimming, has already been observed in India, and in some other regions in the world, by some authors using ground data from the last two decades. The recent interest in the promotion of solar energy applications in India highlights the need of extending and improving the knowledge of the solar radiation resources in this country, since most of the long term measurements available correspond to global horizontal radiation (GHI) and most of them are also located big cities or highly populated areas. In addition, accurate knowledge on the aerosol column quantification and on its dynamical behavior with high spatial resolution is particularly important in the case of India, due to their impact on direct normal irradiation. Long term studies of solar irradiation over India can be performed using monthly means of GHI measurements from the Indian Meteorological Department. Ground data are available from 1964 till today through the World Radiation Data Centre that publish these values in the web. This work shows a long term analysis of GHI using anomalies techniques over ten different sites over India. Besides, techniques of linear trends have been applied for to show the evolution over this period. The analysis of anomalies has also found two periods of different behavior. From 1964 till 1988 the anomalies observed were positive and the last 20 years seems to be a period of negative anomalies. The results exhibit a decreasing trend and negative anomalies confirming thus the darkening effect already reported by solar dimming studies

Research focusing on the usefulness of antidepressants in India has more or less followed the trends seen in the West. Most of the studies conducted in India have evaluated various antidepressants in depression. In this article, we review studies conducted in India on various antidepressants. The data suggests that antidepressants have been evaluated mainly in the acute phase treatment and rare studies have evaluated the efficacy in continuation phase treatment. PMID:21836704

    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

    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.

  2. 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

  3. India's Worsening Uranium Shortage

    Curtis, Michael M.

    2007-01-15

    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.

In India, where bus transport plays an important role in day-to-day commutation, it is of significant interest to analyze its topological structure and answer basic questions on its evolution, growth, robustness and resiliency. Although the common feature of small-world property is observed, our analysis reveals a wide spectrum of network topologies arising due to significant variation in the degree-distribution patterns in the networks. We also observe that these networks although, robust and resilient to random attacks are particularly degree-sensitive. Unlike real-world networks, such as Internet, WWW and airline, that are virtual, bus networks are physically constrained. Our findings therefore, throw light on the evolution of such geographically and constrained networks that will help us in designing more efficient bus networks in the future. PMID:27992590

    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.

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.

    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.

    2016-09-01

    The Precision Reactor Oscillation and SPECTrum Experiment (PROSPECT), is a short baseline, reactor neutrino experiment which focuses on measurements of the flux and energy spectrum of antineutrinos emitted from the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. Using these measurements, PROSPECT will probe for eV-scale sterile neutrinos while making a high precision measurement of the U-235 antineutrino spectrum. PROSPECT contains two phases; the first phase consists of a mobile detector near the reactor core while the second phase adds a larger fixed detector further from the core. The PROSPECT Phase 1 detector consists of a 2ton optically segmented liquid scintillator with each segment read-out by two photomultiplier tubes (PMTs). The PMTs are calibrated with a photon source generated by a nanosecond pulsed laser. In this project, we developed a plan to determine the effectiveness of a 450nm fiber-pigtailed diode laser as it coupled with several modules including an optical fiber splitter, an optical diffuser, and an attenuator. The project tested for the system ability to deliver light uniformly to each of the cells in the detector. We will present the design and result of this project as well as discuss how it will be implemented in PROSPECT.

    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

    Mukhopadhyay, K K

    1995-01-01

    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.

    Following watershed amendments in Schedule Y India's star rose rather rapidly on the clinical research (especially clinical trials) horizon. Just as dramatic was the fall of this empire. At the centre of these events has been the participant and indirectly, the Ethics Committee (EC) that is established primarily to protect this individual. This paper traces the evolution of the concept of ECs in India, examines the current state of these committees in the country and suggests the way forward. The Past: The requirement for an EC to oversee clinical research was first made in the ICMR Policy Statement for Ethics published in 1980 and then again in the Schedule Y (1988). Later, both the Amended Schedule Y (2005) assigned regulatory responsibility on the EC and the ICMR Guidelines (2006) described the functioning of ECs. Several challenges including inadequate formal training, contribution from non-technical members, administrative support as well no SOPs and a heavy workload were identified. In the absence of regulatory oversight of ECs, the introduction of the Clinical Trial Registry - India (CTRI) and self-regulation through voluntary accreditation programs brought a measure of accountability and transparency. The Present: A slew of regulatory reforms led to more than 1000 ECs to be registered with CDSCO although the actual impact on participants' protection and safety of these new regulations still remains to be seen. Way Forward: A method to oversee all ECs, improved functioning of ECs including on site monitoring, central ECs for multicentric studies, the development of metrics to assess the ability of ECs to protect the participant are other ideas for the future. Conclusions: Although ECs in India have evolved from being mere rubber stamps for approval of protocols to efficiently functioning accredited ECs, yet there is much to be done for and by Ethics Committees.

    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

  7. The cost of prospecting for dispersal opportunities in a social bird

    Understanding why individuals delay dispersal and become subordinates within a group is central to studying the evolution of sociality. Hypotheses predict that dispersal decisions are influenced by costs of extra-territorial prospecting that are often required to find a breeding vacancy. Little is known about such costs, partly because it is complicated to demonstrate them empirically. For example, prospecting individuals may be of inferior quality already before prospecting and/or have been evicted. Moreover, costs of prospecting are mainly studied in species where prospectors suffer from predation risk, so how costly prospecting is when predators are absent remains unclear. Here, we determine a cost of prospecting for subordinate Seychelles warblers, Acrocephalus sechellensis, in a population where predators are absent and individuals return to their resident territory after prospecting. Prospecting individuals had 5.2% lower body mass than non-prospecting individuals. Our evidence suggests this may be owing to frequent attacks by resident conspecifics, likely leading to reduced food intake by prospectors. These results support the hypothesis that energetic costs associated with dispersal opportunities are one factor influencing dispersal decisions and shaping the evolution of delayed dispersal in social animals.

    2013-01-01

    Working memory (WM) is fundamental to many aspects of human life, including learning, speech and text comprehension, prospection and future planning, and explicit “system 2” forms of reasoning, as well as overlapping heavily with fluid general intelligence. WM has been intensively studied for many decades, and there is a growing consensus about its nature, its components, and its signature limits. Remarkably, given its central importance in human life, there has been very little comparative investigation of WM abilities across species. Consequently, much remains unknown about the evolution of this important human capacity. Some questions can be tentatively answered from the existing comparative literature. Even studies that were not intended to do so can nonetheless shed light on the WM capacities of nonhuman animals. However, many questions remain. PMID:23754428

    This 12-month prospective randomized cluster trial of 20 dietitians in India compared usual care (UC) and evidence-based nutrition practice guideline (EBNPG) care for patients with type 2 diabetes mellitus. Baseline, 6-month, and 12-month data from 238 patients were analyzed. EBNPG implementation was evaluated using the Ottawa Model for Knowledge Transfer. EBNPG and UC groups achieved significant hemoglobin A1C improvements. EBNPG-treated participants were significantly more likely to meet low-density lipoprotein, high-density lipoprotein, and triglyceride goals at 6 or 12 months. Dietitian dropout, implementation barriers, and undetermined EBNPG intervention fidelity are limitations. Future research should assess barriers/supports and degree of EBNPG use. PMID:28232773

  11. Skewed sex ratios at birth and future marriage squeeze in China and India, 2005-2100.

    2012-02-01

    I examine the potential impact of the anticipated future marriage squeeze on nuptiality patterns in China and India during the twenty-first century. I use population projections from 2005 to 2100 based on three different scenarios for the sex ratio at birth (SRB). To counteract the limitations of cross-sectional methods commonly used to assess the severity of marriage squeezes, I use a two-sex cohort-based procedure to simulate marriage patterns over the twenty-first century based on the female dominance model. I also examine two more-flexible marriage functions to illustrate the potential impact of changes in marriage schedules as a response to the marriage squeeze. Longitudinal indicators of marriage squeeze indicate that the number of prospective grooms in both countries will exceed that of prospective brides by more 50% for three decades in the most favorable scenario. Rates of male bachelorhood will not peak before 2050, and the squeeze conditions will be felt several decades thereafter, even among cohorts unaffected by adverse SRB. If the SRB is allowed to return to normalcy by 2020, the proportion of men unmarried at age 50 is expected to rise to 15% in China by 2055 and to 10% in India by 2065. India suffers from the additional impact of a delayed fertility transition on its age structures.

  12. Prospecting for lunar resources

    NASA Astrophysics Data System (ADS)

    Taylor, G.; Martel, L.

    Large space settlements on the Moon (thousands of people) will require use of indigenous resources to build and maintain the infrastructure and generate products for export. Prospecting for these resources is a crucial step in human migration to space and needs to begin before settlement and the establishment of industrial complexes. We are devising a multi-faceted approach to prospect for resources. A central part of this work is developing the methodology for prospecting the Moon and other planetary bodies. This involves a number of investigations: (1) It is essential to analyze the economics of planetary ore deposits. Ore deposits are planetary materials that we can mine, process, and deliver to customers at a profit. The planetary context tosses in some interesting twists to this definition. (2) We are also making a comprehensive theoretical assessment of potential lunar ore deposits. Our understanding of the compositions, geological histories, and geological processes on the Moon will lead to significant differences in how we assess wh a t types of ores could be present. For example, the bone-dry nature of the Moon (except at the poles) eliminates all ore deposits associated with hydrothermal fluids. (3) We intend to search for resources using existing data for the Moon. Thus, prospecting can begin immediately. We have a wealth of remote sensing data for the Moon. We also have a good sampling of the Moon by the Apollo and Luna missions, and from lunar meteorites. We can target specific types of deposits already identified (e.g. lunar pyroclastic deposits) and look for other geological settings that might have produced ores and other materials of economic value. Another approach we will take is to examine all data available to look for anomalies. Examples are unusual spectral properties, large disagreements between independent techniques that measure the same property, unusual elemental ratios, or simply exceptional properties such as elemental abundances much

    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.

    2013-01-01

    Background People who originate from the Indian subcontinent (South Asians) suffer among the highest rates of type 2 diabetes in the world. Prior evidence suggests that metabolic risk factors develop early in life and are influenced by maternal and paternal behaviors, the intrauterine environment, and genetic factors. The South Asian Birth Cohort Study (START) will investigate the environmental and genetic basis of adiposity among 750 South Asian offspring recruited from highly divergent environments, namely, rural and urban India and urban Canada. Methods Detailed information on health behaviors including diet and physical activity, and blood samples for metabolic parameters and DNA are collected from pregnant women of South Asian ancestry who are free of significant chronic disease. They also undergo a provocative test to diagnose impaired glucose tolerance and gestational diabetes. At delivery, cord blood and newborn anthropometric indices (i.e. birth weight, length, head circumference and skin fold thickness) are collected. The mother and growing offspring are followed prospectively and information on the growth trajectory, adiposity and health behaviors will be collected annually up to age 3 years. Our aim is to recruit a minimum of 750 mother-infant pairs equally divided between three divergent environments: rural India, urban India, and Canada. Summary The START cohort will increase our understanding of the environmental and genetic determinants of adiposity and related metabolic abnormalities among South Asians living in India and Canada.

    Ghose, T K; Bisaria, V S

    2000-01-01

    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

  18. AIDS in India: constructive chaos?

    PubMed

    Chatterjee, A

    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 plan exists for the reduction of AIDS and HIV infection and morbidity. UNICEF programs target mothers and children for AIDS awareness, and blood testing facilities are expected to be expanded. The article considers the present chaos effectively productive in forcing the Indian population to face up to previously taboo issued of sexuality, sex education, and sexually transmitted disease.

    Khatri, G. R.; Frieden, Thomas R.

    2002-01-01

    Since late 1998 the coverage of the DOTS strategy in India has been expanded rapidly. In both 2000 and 2001 the country probably accounted for more than half the global increase in the number of patients treated under DOTS and by early 2002 more than a million patients were being treated in this way in India. As a result, nearly 200 000 lives were saved. The lessons learnt relate to the importance of the following elements of the programme: (1) getting the science right and ensuring technical excellence; (2) building commitment and ensuring the provision of funds and flexibility in their utilization; (3) maintaining focus and priorities; (4) systematically appraising each area before starting service delivery; (5) ensuring an uninterrupted drug supply; (6) strengthening the established infrastructure and providing support for staff; (7) supporting the infrastructure required in urban areas; (8) ensuring full-time independent technical support and supervision, particularly during the initial phases of implementation; (9) monitoring intensively and giving timely feedback; and (10) continuous supervision. Tuberculosis (TB) control still faces major challenges in India. To reach its potential, the control programme needs to: continue to expand so as to cover the remaining half of the country, much of which has a weaker health infrastructure than the areas already covered; increase its reach in the areas already covered so that a greater proportion of patients is treated; ensure sustainability; improve the patient-friendliness of services; confront TB associated with human immunodeficiency virus (HIV) infection. It is expected that HIV will increase the number of TB cases by at least 10% and by a considerably higher percentage if HIV becomes much more widespread. India's experience shows that DOTS can achieve high case-detection and cure rates even with imperfect technology and often with an inadequate public health infrastructure. However, this can only happen if the

    2012-01-01

    The controversy evolution vs. creationism is inherent to the incompatibility between scientific rationalism/empiricism and the belief in supernatural causation. To test this hypothesis, we conceptualized a Cartesian landscape where the dependent variable acceptance of evolution was plotted as function of three factors, each represented by an index (value range 0 to 3): Religiosity Index (RI), Science Index (SI), and Evolution Index (EI). The indexes summarized an individual's personal religious convictions, familiarity with the processes and forces of change in organisms (= concept of evolution), and understanding the essence of science (= method to explore reality). We compared and contrasted acceptance of evolution among four populations of variable educational attainment: 244 professors of New England, United States (93% Ph.D./doctorate holders), 50 protistologists from 25 countries (70% Ph.D./doctorate holders), 62 educators of prospective teachers (83% Ph.D./doctorate holders), and 827 college students. The New England faculty held the highest acceptance of evolution position (RI = 0.49; SI = 2.49; EI = 2.49), followed by the protistologists (RI = 0.46; SI = 2.30; EI = 2.48), the educators of prospective teachers (RI = 0.83; SI = 1.96; EI = 1.96), and the students (RI = 0.89; SI = 1.80; EI = 1.60); therefore, the data supported our hypothesis. Proper science education, public outreach and robust debate over the controversy "evolution versus creationism" should suffice to improve society's evolution literacy, and qualified scholars ought to lead this mission.

    AIM To describe, using gait analysis, the development of spinal motion in the growing child. METHODS Thirty-six healthy children aged from 3 to 16 years old were included in this study for a gait analysis (9 m-walk). Various kinematic parameters were recorded and analyzed such as thoracic angle (TA), lumbar angle (LA) and sagittal vertical axis (SVA). The kinetic parameters were the net reaction moments (N.m/kg) at the thoracolumbar and lumbosacral junctions. RESULTS TA and LA curves were not statistically correlated to the age (respectively, P = 0.32 and P = 0.41). SVA increased significantly with age (P < 0.001). Moments in sagittal plane at the lumbosacral junction were statistically correlated to the age (P = 0.003), underlining the fact that sagittal mechanical constraints at the lumbosacral junction increase with age. Moments in transversal plane at the thoracolumbar and lumbosacral junctions were statistically correlated to the age (P = 0.0002 and P = 0.0006), revealing that transversal mechanical constraints decrease with age. CONCLUSION The kinetic analysis showed that during growth, a decrease of torsional constraint occurs while an increase of sagittal constraint is observed. These changes in spine biomechanics are related to the crucial role of the trunk for bipedalism acquisition, allowing stabilization despite lower limbs immaturity. With the acquisition of mature gait, the spine will mainly undergo constraints in the sagittal plane. PMID:28361018

    Prospectors have contributed much to the development of this Nation's mineral resources. Since the time of the earliest settlement, the need for iron for tools and guns, lead for bullets, and copper for utensils has prompted a search for sources of these metals. The lure of gold and silver provided the impetus for much of the development in the West between 1850 and 1910. Later, prospectors carried out successful ventures to fulfill the country's expanding industrial demands for other metals such as zinc, molybdenum, tungsten, chromium, vanadium, and many others. Even America's uninhabited rugged mountains or barren deserts have been prospected although perhaps only at a reconnaissance scale.

  13. Methane Clathrate Hydrate Prospecting

    Duxbury, N.; Romanovsky, V.

    2003-01-01

    A method of prospecting for methane has been devised. The impetus for this method lies in the abundance of CH4 and the growing shortages of other fuels. The method is intended especially to enable identification of subpermafrost locations where significant amounts of methane are trapped in the form of methane gas hydrate (CH4(raised dot)6H2O). It has been estimated by the U.S. Geological Survey that the total CH4 resource in CH4(raised dot) 6H2O exceeds the energy content of all other fossil fuels (oil, coal, and natural gas from non-hydrate sources). Also, CH4(raised dot)6H2O is among the cleanest-burning fuels, and CH4 is the most efficient fuel because the carbon in CH4 is in its most reduced state. The method involves looking for a proxy for methane gas hydrate, by means of the combination of a thermal-analysis submethod and a field submethod that does not involve drilling. The absence of drilling makes this method easier and less expensive, in comparison with prior methods of prospecting for oil and natural gas. The proposed method would include thermoprospecting in combination with one more of the other non-drilling measurement techniques, which could include magneto-telluric sounding and/or a subsurface-electrical-resistivity technique. The method would exploit the fact that the electrical conductivity in the underlying thawed region is greater than that in the overlying permafrost.

    Incidence of skin cancers has been increasing since the last few decades worldwide. Nonmelanoma skin cancer (NMSC) is the commonest variety of cutaneous malignancy. Conventional wisdom has it that the incidence of all varieties of skin cancers is lower among Indians due to the protective effects of melanin. Though national surveys and cross-country data in India are unavailable, there are indirect indications from several smaller reports that NMSCs may be on the rise in India. Reports of quite a few atypical cases lead us to hypothesize that factors other than ultraviolet radiation may be important in the occurrences of these cancers, particularly in the skin types prevalent in India. The descriptive epidemiology and clinical characteristics of squamous and basal cell carcinoma in India, including their variants, are discussed here along with hypotheses on their etiopathogenesis. Novel management techniques currently available in India are also highlighted.

    Rheumatology has been a neglected subspecialty in India. A staggering patient load, a severely inadequate number of trained rheumatology specialists, therapeutic nihilism and limited advocacy are some of the critical challenges that confront rheumatology care, and possibly explain the high rates of reliance on complementary and alternative medicines in India. Disease spectrum and treatment patterns are not remarkably different from those in other countries, but biologic agents have limited use and are administered for short periods only. Consequently, outcomes in India do not yet match those reported in developed countries. Furthermore, the high prevalence of infectious diseases continues to be a major contributor to mortality in patients with rheumatic disorders such as systemic lupus erythematosus. Several tropical diseases with rheumatic manifestations are relevant in India, including chikungunya, brucellosis, leptospirosis, dengue and melioidosis. To address the many problems with rheumatology care in India, curricular reforms, capacity building, patient education and political support are sorely needed.

    2008-11-01

    The emerging viral diseases haemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) are a cause of global concern as they are increasingly reported from newer regions of the world. The hantavirus species causing HFRS include Hantaan virus,Seoul virus, Puumala virus, and Dobrava-Belgrade virus while Sin Nombre virus was responsible for the 1993 outbreak of HCPS in the Four Corners Region of the US. Humans are accidental hosts and get infected by aerosols generated from contaminated urine,feces and saliva of infected rodents. Rodents are the natural hosts of these viruses and develop persistent infection. Human to human infections are rare and the evolution of the virus depends largely on that of the rodent host. The first hantavirus isolate to be cultured, Thottapalayam virus,is the only indigenous isolate from India,isolated from an insectivore in 1964 in Vellore, South India. Research on hantaviruses in India has been slow but steady since 2005. Serological investigation of patients with pyrexic illness revealed presence of anti-hantavirus IgM antibodies in 14.7% of them. The seropositivity of hantavirus infections in the general population is about 4% and people who live and work in close proximity with rodents have a greater risk of acquiring hantavirus infections. Molecular and serological evidence of hantavirus infections in rodents and man has also been documented in this country. The present review on hantaviruses is to increase awareness of these emerging pathogens and the threats they pose to the public health system.

    The rapid population growth in urban India has outpaced the municipal capacity to build essential infrastructures that make life in cities safe and healthy. Local and national governments alike are grappling with the challenges of urbanization with thousands migrating from villages to cities. Thus, urbanization in India has been accompanied by a concentration of poverty and urban public healthcare has emerged as one of the most pressing priorities facing our country. Newborn mortality rates in urban settings are lower than rural areas, early neonatal deaths account for greater proportion than late neonatal deaths. The available evidence suggests that socio-economic inequalities and poor environment pose major challenges for newborn health. Moreover, fragmented and weak public health system, multiplicity of actors and limited capacity of public health planning further constrain the delivery of quality and affordable health care service. Though healthcare is concentrated in urban areas, delay in deciding to seek health care, reaching a source of it and receiving appropriate care affects the health outcomes disproportionately. However, a few city initiatives and innovations piloted in different states and cities have brought forth the evidences of effectiveness of different strategies. Recently launched National Urban Health Mission (NUHM) provides an opportunity for strategic thinking and actions to improve newborn health outcomes in India. There is also an opportunity for coalescence of activities around National Health Mission (NHM) and Reproductive, Maternal, Newborn and Child Health+Adolescent (RMNCH+A) strategy to develop feasible and workable models in different urban settings. Concomitant operational research needs to be carried out so that the obstacles, approaches and response to the program can be understood. PMID:27924107

    Integrated economic models have been used to project both baseline and mitigation greenhouse gas emissions scenarios at the country and the global level. Results of these scenarios are typically presented at the sectoral level such as industry, transport, and buildings without further disaggregation. Recently, a keen interest has emerged on constructing bottom up scenarios where technical energy saving potentials can be displayed in detail (IEA, 2006b; IPCC, 2007; McKinsey, 2007). Analysts interested in particular technologies and policies, require detailed information to understand specific mitigation options in relation to business-as-usual trends. However, the limit of information available for developing countries often poses a problem. In this report, we have focus on analyzing energy use in India in greater detail. Results shown for the residential and transport sectors are taken from a previous report (de la Rue du Can, 2008). A complete picture of energy use with disaggregated levels is drawn to understand how energy is used in India and to offer the possibility to put in perspective the different sources of end use energy consumption. For each sector, drivers of energy and technology are indentified. Trends are then analyzed and used to project future growth. Results of this report provide valuable inputs to the elaboration of realistic energy efficiency scenarios.

    Antipsychotic as a class of medications became available for treatment of various psychiatric disorders in the early 1950’s. Over the last 60 years many antipsychotics have become available. In line with the west, Indian researchers have evaluated the efficacy of antipsychotics in various conditions. Additionally, researchers have also evaluated the important safety and tolerability issues. Here, we review data originating from India in the form of drug trials, effectiveness, usefulness, safety and tolerability of antipsychotics. Additionally, data with respect to other important treatment related issues is discussed. PMID:21836703

    We explore the impact of sociodemographic change on marriage patterns in India by examining the hypothetical consequences of applying three sets of marriage pairing propensities-contemporary patterns by age, contemporary patterns by age and education, and changing propensities that allow for greater educational homogamy and reduced educational asymmetries--to future population projections. Future population prospects for India indicate three trends that will impact marriage patterns: (1) female deficit in sex ratios at birth; (2) declining birth cohort size; (3) female educational expansion. Existing literature posits declining marriage rates for men arising from skewed sex ratios at birth (SRBs) in India's population. In addition to skewed SRBs, India's population will experience female educational expansion in the coming decades. Female educational expansion and its impact on marriage patterns must be jointly considered with demographic changes, given educational differences and asymmetries in union formation that exist in India, as across much of the world. We systematize contemporary pairing propensities using data from the 2005-2006 Indian National Family Health Survey and the 2004 Socio-Economic Survey and apply these and the third set of changing propensities to multistate population projections by educational attainment using an iterative longitudinal projection procedure. If today's age patterns of marriage are viewed against age/sex population composition until 2050, men experience declining marriage prevalence. However, when education is included, women--particularly those with higher education--experience a more salient rise in nonmarriage. Significant changes in pairing patterns toward greater levels of educational homogamy and gender symmetry can counteract a marked rise in nonmarriage.

    One of the latest attempts to explore the interface between physics and geophysics is the extravagant scheme of Alvaro De Rújula, Sheldon Glashow, Robert Wilson, and Georges Charpak, to be published in Physics Reports. In what these theoretical and experimental physicists described recently as “our mad project” (Physics Today, August 1983), a high-energy neutrino beam is to be used as a geophysical prospecting tool.The beam would be able to look for oil, natural gas, and high-atomic-number metal ores, and it would be able to profile the vertical density distribution of the earth. De Rújula et al. come to this project from the world of big physics machines, so it is natural to expect that the “Geotron,” the field instrument to supply and focus the neutrino beam, is to be big also.

The emphasis is on unfinished business: issues that have been recognized for some time, but not yet resolved. Then I turn to prospects for proton-proton colliders to explore the 1-TeV scale. I review the motivation for new physics in the neighborhood of 1 TeV and mention some discovery possibilities for high-energy, high-luminosity hadron colliders and the implications they would have for neutrino physics. I raise the possibility of the direct study of neutrino interactions in hadron colliders. I close with a report on the status of the SSC project. 38 refs., 17 figs.

    The evolutionary history of thecamoebians (testate amoebae) extends back to the Neoproterozoic Era. However, until now, these have had a restricted, discontinuous and modest record across the world. The studied sediment of Raniganj Formation (Godavari Graben), Andhra Pradesh, India has been assigned as Late Permian on the basis of co-occurring age-diagnostic Late Permian palynomorphs. About sixteen thecamoebian species and one taxon incertae sedis have been recorded here in the palynological slides on the basis of shell morphology and morphometry. Out of these, five belong to the family Arcellidae, seven to Centropyxidae, two to Trigonopyxidae, one to Difflugiidae, one to Plagiopyxidae, and one is regarded incertae sedis. The morphometric characteristics of fossil forms resemble their corresponding extant species studied from ecologically diverse fresh water wetlands in India. In general, the ratio of shell diameter and aperture diameter of Late Permian fossil and extant specimens show significant correlation in all the studied species. Except that, the ratio of shell length and breadth is the distinguishing feature between Centropyxis aerophila and C. aerophila 'sylvatica', rather than the ratio of shell length and longest diameter of the shell aperture in both fossil and extant forms. The study elucidates the minimal morphological evolution in thecamoebians and their survival during mass extinction periods and stressful environmental conditions over the geological timescale.

    An important prerequisite for the evaluation of any sedimentary basin is the understanding of its regional tectonic setting. This is especially so in the underexplored regions of Africa. The majority of African sedimentary basins developed in an extensional setting although some have undergone subsequent compressional or transpressional deformation. The geometry and evolution of these basins is often influenced by basement structure. The extensional phase of basin development controls not only the distribution of syn-rift sediments but also the magnitude of post-rift regional subsidence and the preservation or removal of pre-rift sediments. This has important consequences for exploration models of syn-rift and pre-rift source rocks and reservoirs. Post-rift basin inversion and uplift provide crucial controls on the preservation of mature source rocks and quality of reservoirs. The distribution, nature, timing, and possible mechanisms of this uplift in Africa will be addressed. The hydrocarbon prospectivity of African basis appears to be highly variable although the limited exploration of some regions makes the exact extent of this variability unclear. Basins considered potentially prospective range from late Precambrian to Tertiary in age. The various tectonic controls outlined above, and criteria for the evaluation of underexplored areas, will be demonstrated by reference to basins studied by The Robertson Group. Examples described include basins from Bagon, Angola, Namibia, East Africa, Tertiary Rift and Karoo Rifts, and North Africa (Sudan, Egypt, Algeria, and Morocco).

    The discovery of neutrino oscillations commenced exploration of a rich field of science at the intersection of nuclear, particle and astrophysics. This brought a number of interesting questions related to the neutrinos to the forefront of scientific literature. PROSPECT, the Precision Reactor Oscillation and Spectrum Experiment, aims to help answer some of those questions by precisely measuring the antineutrino flux and energy spectrum 7-9 meters from the highly enriched 235U reactor core at Oak Ridge National Laboratory's High Flux Isotope Reactor (HFIR) with the goal to probe much of the best fit sterile neutrino parameter space. To better probe the sterile neutrino best fit region it is important to minimize the systematic uncertainties, requiring a detailed characterization of the background radiation field. Here we present DANG (the Detector Array to measure Neutron and Gamma radiation), an array deployed at HFIR to characterize spatial and time variations of the emitted background radiation. The array scans the entire proposed volume of the future PROSPECT location, providing a 3-d map of the background. Additionally, the array allows the study of the time evolution of HFIR correlated background to better understand how the reactor's prompt and activation radiation changes as function of the reactor cycle. Both a discussion of the construction and operation of the array will be given as well as a look at first results.

    Microbial ecology is revealing the vast diversity of strains and species that coexist in many environments, ranging from free-living communities to the symbionts that compose the human microbiome. In parallel, there is growing evidence of the importance of cooperative phenotypes for the growth and behavior of microbial groups. Here we ask: How does the presence of multiple species affect the evolution of cooperative secretions? We use a computer simulation of spatially structured cellular groups that captures key features of their biology and physical environment. When nutrient competition is strong, we find that the addition of new species can inhibit cooperation by eradicating secreting strains before they can become established. When nutrients are abundant and many species mix in one environment, however, our model predicts that secretor strains of any one species will be surrounded by other species. This "social insulation" protects secretors from competition with nonsecretors of the same species and can improve the prospects of within-species cooperation. We also observe constraints on the evolution of mutualistic interactions among species, because it is difficult to find conditions that simultaneously favor both within- and among-species cooperation. Although relatively simple, our model reveals the richness of interactions between the ecology and social evolution of multispecies microbial groups, which can be critical for the evolution of cooperation.

    A protein malnutrition survey was carried out in ten areas of four States of South India among children under 5 years of age in families with a monthly income of less than Rs 100, estimated to constitute 85% of the population. The agricultural situation and socio-economic conditions are described. The diets investigated consisted largely of cereals, with small quantities of pulses and green vegetables; milk, meat and eggs were little eaten. The survey covered investigation of infant care, feeding and weaning practices, clinical examinations, anthropometric measurements, determinations of haemoglobin and serum protein, and analysis of hospital records. Although infants were usually breast-fed for a long time, the quantity of breast milk was found to be low after 6 months, at which time supplementary foods were introduced, but these were usually inadequate. Extreme growth retardation was seen after weaning. Diarrhoea was complained of in some 20% of children. Such deficiency signs as dyschromotrichia, hepatomegaly, moon face, angular stomatitis and xerophthalmia were frequently seen. Frank cases of kwashiorkor and marasmus were observed in 1% and 1.7% respectively of children at home. These findings and others clearly show protein malnutrition to be a problem of very considerable magnitude in the poorer communities of South India. A comparison is made with the results of surveys conducted in Africa and in Central America. ImagesFIG. 6FIG. 7FIG. 2 PMID:14436226

    The Indian Space programme took birth on November 21, 1963, with the launch of Nike-Apache, an American sounding rocket from the shores of Thumba near Thiruvananthapuram on the west coast of India. From a family of operational sounding rockets known as the Rohini Sounding Rockets, India's launch vehicles have now grown up through SLV-3 and Augmented Satellite Launch Vehicle (ASLV) to the current gigantic satellite launchers, PSLV and Geosynchronous Satellite Launch Vehicle (GSLV). Though we had failures in the initial launches of SLV-3, ASLV and PSLV, these failures gave Indian Space Research Organisation (ISRO) a thorough and in depth understanding of the nuances of launch vehicle technology that later led to successful missions. An entirely new dimension was added to the Indian space programme when a space capsule was recovered very precisely after it had orbited the Earth for 12 days. The future for launch vehicles in ISRO looks bright with the GSLV MKIII, which is currently under development and the pursuit of cutting edge technologies such as reusable launch vehicles and air-breathing propulsion.

    Test results from clinical laboratories must ensure accuracy, as these are crucial in several areas of health care. It is necessary that the laboratory implements quality assurance to achieve this goal. The implementation of quality should be audited by independent bodies,referred to as accreditation bodies. Accreditation is a third-party attestation by an authoritative body, which certifies that the applicant laboratory meets quality requirements of accreditation body and has demonstrated its competence to carry out specific tasks. Although in most of the countries,accreditation is mandatory, in India it is voluntary. The quality requirements are described in standards developed by many accreditation organizations. The internationally acceptable standard for clinical laboratories is ISO15189, which is based on ISO/IEC standard 17025. The accreditation body in India is the National Accreditation Board for Testing and Calibration Laboratories, which has signed Mutual Recognition Agreement with the regional cooperation the Asia Pacific Laboratory Accreditation Cooperation and with the apex cooperation the International Laboratory Accreditation Cooperation.

    India has a rich and diversified flora. It is seen that synthetic drugs could pose serious problems, are toxic and costly. In contrast to this, herbal medicines are relatively nontoxic, cheaper and are eco-friendly. Moreover, the people have used them for generations. They have also been used in day-to-day problems of healthcare in animals. 25% of the drugs prescribed worldwide come from plants. Almost 75% of the medicinal plants grow naturally in different states of India. These plants are known to cure many ailments in animals like poisoning, cough, constipation, foot and mouth disease, dermatitis, cataract, burning, pneumonia, bone fractures, snake bites, abdominal pains, skin diseases etc. There is scarce review of such information (veterinary herbals) in the literature. The electronic and manual search was made using various key words such as veterinary herbal, ethno-veterinary medicines etc. and the content systematically arranged. This article deals with the comprehensive review of 45 medicinal plant species that are official in Indian Pharmacopoeia (IP) 2014. The botanical names, family, habitat, plant part used and pharmacological actions, status in British Pharmacopoeia 2014, USP 36 are mentioned.

    The 1 issue, more than anything else, that cost Indira Gandhi the election in India was her mass sterilization campaign. Although no one questions India's need for an effective family planning program, the government's program to vasectomize millions of Indian men who had fathered 2 or more children was ruthlessly and often illegally applied and came to symbolize the dangers of authoritarian rule. The program's target was 4.3 million sterilizations; the campaign produced 7.8 million between April 1976 and January 1977. In an effort to ensure the program's success, the government censors prohibited newspapers from publishing any criticism of family planning. 6 months ago the Family Planning Council claimed that "a most favorable climate" has been created for the voluntary acceptance of sterilization. In a recent tour of the Indian countryside this claim was found to be untrue. None of the villagers this writer spoke to had been offered any guidance by a family planning worker. There had been no explanation, for example, that sterilization is not responsible for impotence. By last week when the votes were counted, the pattern was clear. In states where the sterilization program had been pursued with the most zeal but the least preparation, the defection from the Congress Party was the most severe.

  20. Globalisation and women in India.

    PubMed

    Krishnaraj, M

    1999-11-01

    Globalization arrived in India through an external and internal alignment of political and economic forces that led to the opening of the country to the outside world. The five processes under globalization are: 1) commercialism wherein more services become monetized and incomes are received in money rather than in kind; 2) more capitalization; 3) foreign trade becomes important for the production and distribution process; 4) greater financialization develops; and 5) international capital moves freely. These changes affect women more than men in different ways. Capitalization results in more self-employed marginal farmers becoming wage workers, making it less possible for women to manage domestic duties alongside their productive work. In general, macro-economic policies affect women through the household, market, and gender relations. In countries like India where women suffer from serious discrimination, whatever affects the household will worsen women's position. Thus, the process of liberalization, privatization, and globalization will put the clock back for women and for the poor in general.

  1. The timing of India-Asia collision onset - facts, theories, controversies

    The timing of initial collision between India and Asia has remained grossly and windingly controversial for half a century. This paper attempts to review this crucial and hotly debated argument, describing first the different methods used to constrain the age of collision and discussing next the rationale, results, inferences and problems associated with each. We conclude that stratigraphy represents the best direct way to unravel collision chronology. Other methods focusing on the magmatic, metamorphic or paleomagnetic record provide additional fundamental constraints, but cannot provide a robust direct estimate of collision onset. Initial collision in the central-eastern Himalaya is dated directly at the Middle Paleocene (59±1 Ma) by the abrupt change in sediment provenance recorded in trench settings (Hu et al., 2015). The quasi-synchronous unconformities documented along both Tethyan passive margin of India and active margin of Asia from Tibet to Zanskar-Ladakh confirm that orogeny was underway at the close of the Paleocene (56 Ma) (Garzanti et al., 1987; Li et al., 2015; Hu et al., 2016), well before the disappearance of marine seaways in the Himalaya during the Eocene (50 Ma) (Najman et al., 2010). Sedimentary evolution and provenance changes in marine to fluvio-deltaic successions are recorded synchronously within error from the western to the central-eastern Himalaya, failing to provide evidence for diachronous collision. These coherent observations are hard to reconcile with three widely cited hypotheses invoking either earlier events of arc-continent collision or ophiolite obduction, or the protracted existence of a Greater India Basin, which should be all rejected after discussing the geological evidence. A scenario no more complex than the one involving solely the passive continental margin of India and the active continental margin of Asia is needed to explain the geological evolution of the nascent Himalaya.

    The study of the nose is as old as civilisation. Various conditions affecting its structure and function has been documented in Edwin Smith Papyrus in hieroglyphic script, an Egyptian writing system of the mid -4th Millennium BC.The major contribution for the complete reconstruction of the nose originated in India by Sushruta in around 600 BC. Writing in Sanskrit in the form of verses he described in detail the technique of total reconstruction, which is still being practiced today as Indian Rhinoplasty. This surgical reconstruction paved the way to modern plastic surgery in Europe and United States in 18th century. Sushruta contributed not only to the plastic surgery of the nose, but described entire philosophy of Head and Neck and other surgery as well. Other notable contributors were Greek physicians, Hippocrate and Galen, and at the birth of the Christianity, Celsus wrote eight books of medical encyclopaedia, which described various conditions affecting nose.Septal and Sinus surgery, in comparison to rhinoplasty did not develop until 17th century. Septal surgery began with total septectomy, sub mucous resection by Killian & Freer in early 20th century and later septoplasty by Cottle in middle of 20th century.Sinus surgery probably originated in Egypt, where instruments were used to remove brain through the ethmoid sinuses as part of the mummification process. In 18th century, empyema of the maxillary sinus was drained through the tooth socket or anterior wall of the sinus, which lead to the evolution of radical procedures of removal of mucous membrane and inferior meatal antrostomy. In the late 20th century, improved understanding of the mucociliary mechanism described by Prof. Messerklinger and Nasal Endoscopy described by Prof. Draf with the development of fibre optics and CT imaging, heralded a new era, which evolved in functional endoscopic sinus surgery. New technology further enhanced the scope of endoscope being used "around and beyond" the nose.

    In India, cervical cancer is the most common woman-related cancer, followed by breast cancer. The rate of cervical cancer in India is fourth worldwide. Two vaccines, Gardasil and Cervarix, both targeting HPV-16 and 18 which account for 70% of invasive cervical carcinomas, are licensed in the United States and numerous countries worldwide. Both vaccine formulations have shown excellent efficacy with minimal toxicity in active female population but numerous questions arise in vaccinating like cost effectiveness, lack of proven efficacy against other HPV strains, social acceptance of HPV vaccination and other ethical issues. The main objective of this study is to emphasis the advantages and disadvantages of the vaccination in India.

    Any national cuisine is a sum total of its variety of regional cuisines, which are the cultural and historical identifiers of their respective regions. India is home to a number of regional cuisines that showcase its culinary diversity. Here, we study recipes from eight different regional cuisines of India spanning various geographies and climates. We investigate the phenomenon of food pairing which examines compatibility of two ingredients in a recipe in terms of their shared flavor compounds. Food pairing was enumerated at the level of cuisine, recipes as well as ingredient pairs by quantifying flavor sharing between pairs of ingredients. Our results indicate that each regional cuisine follows negative food pairing pattern; more the extent of flavor sharing between two ingredients, lesser their co-occurrence in that cuisine. We find that frequency of ingredient usage is central in rendering the characteristic food pairing in each of these cuisines. Spice and dairy emerged as the most significant ingredient classes responsible for the biased pattern of food pairing. Interestingly while individual spices contribute to negative food pairing, dairy products on the other hand tend to deviate food pairing towards positive side. Our data analytical study highlighting statistical properties of the regional cuisines, brings out their culinary fingerprints that could be used to design algorithms for generating novel recipes and recipe recommender systems. It forms a basis for exploring possible causal connection between diet and health as well as prospection of therapeutic molecules from food ingredients. Our study also provides insights as to how big data can change the way we look at food.

    Objectives: There is paucity of information regarding clinical profile of hypopituitarism from India. We report the clinical profile of hypopituitarism from a tertiary center in North India. Materials and Methods: This study was carried out in patients attending our endocrine center between January 2010 and December 2011. All new patients were studied prospectively and those registered before January 2010 retrospectively. Relevant clinical, hormonal, and imaging data were collected. Dynamic testing for pituitary functions was carried out as necessary. Hormonal deficiencies were defined as per prevailing recommendations. Results: This study included 113 subjects. The mean age was 38.6 ± 17.8 years (range, 4 – 76 years). There were 78 (69%) males and 35 females (31%). There were 22 subjects aged ≤18 years (childhood and adolescence) and 91 adults (>18 years). Visual disturbances were the most common presenting complaint (33%), though headache was the most common symptom (81%). Fifteen percent presented with pituitary apoplexy. Tumors comprised of 84% of cases. Hypogonadism (97%) was the most common abnormality seen followed by hypothyroidism (83.2%), hypoadrenalism (79.6%), growth hormone deficiency (88.1% of the 42 patients tested), and diabetes insipidus (13.3%). Panhypopituitarism was seen in 104 (92%) patients. There were no cases of hypopituitarism secondary to traumatic brain injury, subarachnoid hemorrhage, central nervous system infections, or cranial irradiation to extrasellar tumors. Conclusion: The most common cause of hypopituitarism at tertiary care center is pituitary tumors and the commonest presenting complaint is visual symptoms. Panhypopituitarism is present in 92% cases.

    Any national cuisine is a sum total of its variety of regional cuisines, which are the cultural and historical identifiers of their respective regions. India is home to a number of regional cuisines that showcase its culinary diversity. Here, we study recipes from eight different regional cuisines of India spanning various geographies and climates. We investigate the phenomenon of food pairing which examines compatibility of two ingredients in a recipe in terms of their shared flavor compounds. Food pairing was enumerated at the level of cuisine, recipes as well as ingredient pairs by quantifying flavor sharing between pairs of ingredients. Our results indicate that each regional cuisine follows negative food pairing pattern; more the extent of flavor sharing between two ingredients, lesser their co-occurrence in that cuisine. We find that frequency of ingredient usage is central in rendering the characteristic food pairing in each of these cuisines. Spice and dairy emerged as the most significant ingredient classes responsible for the biased pattern of food pairing. Interestingly while individual spices contribute to negative food pairing, dairy products on the other hand tend to deviate food pairing towards positive side. Our data analytical study highlighting statistical properties of the regional cuisines, brings out their culinary fingerprints that could be used to design algorithms for generating novel recipes and recipe recommender systems. It forms a basis for exploring possible causal connection between diet and health as well as prospection of therapeutic molecules from food ingredients. Our study also provides insights as to how big data can change the way we look at food. PMID:26430895

    With the attendant rise of the number of medical colleges in India over past few decades, the demand for cadavers used in medical education and research is growing. However, there is an insufficient supply of donated cadavers available for dissection. This study was undertaken to assess the general population's awareness of body donation programs and willingness to donate in the State of Maharashtra, India. The willingness of participants to donate was compared with age, gender, and education of the respondents. A total of 625 adult individuals from the State of Maharashtra participated in a survey composed of questions about age, sex, education, awareness of body donation programs, and willingness to donate. It was found that 90.9% of the medical colleges surveyed reported an inadequate supply of cadavers. Of the general population, 32.1% of respondents were aware of body donation, compared to 95.83% of health care professionals. However, only 19.5% of the general population and 44.9% of health care professionals were willing to donate their bodies for anatomical education. Younger age groups, males, graduates, and postgraduates were found more willing to donate their bodies. Organ donation was preferred over body donation. A lack of awareness about body donation was the main factor responsible for respondents' "no body donation" response in the general population, along with firm religious beliefs and customs, the fear that the donated body will not be treated with respect and dignity, and the unacceptability of the dissection of one's own body. To overcome the current shortage of donated cadavers, efforts should be undertaken to change the mindset of the wider Indian society toward body donation. The authors believe this is possible through awareness campaigns and that prospective donors' concerns should be addressed appropriately. Proper guidance and assistance regarding body donation should be easily available for potential donors.

    We can summarize the IPY goals as: (a) make major advances in polar knowledge and understanding; (b) leave a legacy of new or enhanced observational systems, facilities and infrastructure; (c) excite a new generation of polar scientists and engineers, and (d) elicit exceptional interest and participation from polar residents, schoolchildren, the general public, and decision-makers, worldwide. This talk reports on the progress and prospects in each of those areas from an overall international view; separate talks will describe details of future researcher and the IPY outreach efforts. To achieve major advances in knowledge, IPY has entrained the intellectual resources of thousands of scientists, many more than expected, often from 'non- polar' nations, and representing an unprecedented breadth of scientific specialties; integration of those efforts across disciplines to achieve integrated system-level understanding remains a substantial challenge. Many national and international organizations prepare plans to sustain new and improved observational systems, but clear outcomes and the necessary resources remain elusive. International outreach networks gradually build breadth and strength, largely through IPY Polar Science Days and other internationally- coordinated IPY events. A new Association of Polar Early Career Scientists (APECS) devotes talent and energy to shaping the future of polar research. These activities and networks may, with time and with continued international coordination, achieve an exceptional level of interest and participation. In all areas, much work remains.

  9. German energy technology prospects.

    After more than 25 years of development of nuclear power and almost 10 years of research and development in numerous areas of nonnuclear energy, there is now a good basis for judging the future prospects of energy technologies in the Federal Republic of Germany. The development of nuclear power has provided an important and economically advantageous new source of energy. Further efforts are needed to establish the nuclear fuel cycle in all stages and to exploit the potential of advanced reactors. In all other areas of energy technology, including energy conservation, new energy sources, and coal, economics has turned out to be the key problem, even at today's energy prices. Opportunities to overcome these economic problems through additional R & D are limited. There is some potential for special applications, and there are many technologies that could contribute to the energy supply of developing countries. In general, however, progress in energy conservation and the use of renewable energy sources will depend on the degree to which energy policy measures can improve their economic basis. For some technologies, such as solar thermal power stations and coal liquefaction, large-scale economic deployment cannot be foreseen today. Instead of establishing costly demonstration projects, emphasis will be put on improving key components of these technologies with the aim of having the most advanced technology available when the economic parameters are more favorable.

    The Central Drugs Standard Control Organisation and its chairman Drug Controller general of India are bequeathed to protect the citizens from the marketing of unsafe medication. The startling findings, of the 59threport of the Parliamentary Standing Committee on Health and Family Welfare, have uncovered the lax standards followed by the regulatory authorities in India. The growing clinical research after the product patents rights for the pharmaceutical industries as per the trade related aspects of intellectual property rights agreement and adverse drug reaction monitoring of the marketed drugs have raised many ethical and regulatory issues regarding the promotion of new drugs in Indian markets. Many controversial group of medicines; unauthorised and irrational FDCs not relevant to India's medical needs, are available which are not sold in any of the countries with matured regulatory bodies. It becomes vital to understand the history, growth and evolution of the regulatory aspects of drugs which are handled by multiple Ministries and Departments of the Government of India. Although amendment to Schedule Y, registration of Contract Research Organisations, registration of Clinical Trials, Speeding up review process, Pharmacovigilance (PhV) programme for India and Inspection of clinical trial sites have been started by the various regulatory agencies. However due to casual approach in marketing approval for sale of the drugs, the unethical steps taken by some pharmaceutical companies and medical practitioners has reiterated the need to get appropriate understanding of present regulation of drugs and clinical research especially regarding the practical rules and regulations.

  14. Prehistoric human colonization of India.

    PubMed

    Misra, V N

    2001-11-01

    Human colonization in India encompasses a span of at least half-a-million years and is divided into two broad periods, namely the prehistoric (before the emergence of writing) and the historic (after writing). The prehistoric period is divided into stone, bronze and iron ages. The stone age is further divided into palaeolithic, mesolithic and neolithic periods. As the name suggests, the technology in these periods was primarily based on stone. Economically, the palaeolithic and mesolithic periods represented a nomadic, hunting-gathering way of life, while the neolithic period represented a settled, food-producing way of life. Subsequently copper was introduced as a new material and this period was designated as the chalcolithic period. The invention of agriculture, which took place about 8000 years ago, brought about dramatic changes in the economy, technology and demography of human societies. Human habitat in the hunting-gathering stage was essentially on hilly, rocky and forested regions, which had ample wild plant and animal food resources. The introduction of agriculture saw it shifting to the alluvial plains which had fertile soil and perennial availability of water. Hills and forests, which had so far been areas of attraction, now turned into areas of isolation. Agriculture led to the emergence of villages and towns and brought with it the division of society into occupational groups. The first urbanization took place during the bronze age in the arid and semi-arid region of northwest India in the valleys of the Indus and the Saraswati rivers, the latter represented by the now dry Ghaggar-Hakra bed. This urbanization is known as the Indus or Harappan civilization which flourished during 3500-1500 B.C. The rest of India during this period was inhabited by neolithic and chalcolithic farmers and mesolithic hunter-gatherers. With the introduction of iron technology about 3000 years ago, the focus of development shifted eastward into the Indo-Gangetic divide and

    Zika virus, which originated from a forest in Uganda, has affected countries in Africa, Latin America and Asia. Most people infected with Zika are asymptomatic and present with clinical manifestations ranging from mild fever to severe neurological disorders. Recent outbreaks in Southeast Asian countries, Centers for Disease Control and Prevention has warned pregnant woman to avoid nonessential traveling to 11 Asian countries. Reports about the sexual transmission route of Zika have pushed the World Health Organization to declare it a 'public health emergency'. Having this current warning status, it has become mandatory to consider where second highly populated country India stands in terms of spreading awareness and taking precautionary measures against the Zika virus infection. Therefore, this paper aims to highlight the importance of Zika in Indian population by considering several indicators such as the population size and ratio, rates of mortality, closely related diseases, government initiatives, and other micro-level factors which are prone to Zika effects.

    This article examines demand factors for sophisticated medical treatments offered by private hospitals operating in India. Three types of medical tourism exist: Outbound, Inbound, and Intrabound. Increased profitability and positive growth trends by private hospital chains can be attributed to rising domestic income levels within India. Not all of the chains examined were financially solvent. Some of the hospital groups in this sample that advertised directly to potential Inbound medical tourists appear to be experiencing negative cash flows.

    The field of population geography was first introduced during the 1960s in India and advanced under the direction of Gosal at the Punjab University. Teaching and research in population geography were introduced by Chandigarh at Punjab University, which today is the main center of research activity. Population geography in India has followed the main tenets of geography in general and is based on spatial perspectives. Deficits are apparent in the paucity of research on socioeconomic implications of spatial distributions, but there is infrastructural feedback to support theory development. Theoretical advances moving from theory to fact or from empirical fact to theory are limited. Comprehensive training in methodology and quantitative techniques is needed for further development of population theory: multivariate analysis, factor analysis, principal component analysis, model building, hypothesis testing, and theory formulation. Methodological sophistication will also help in understanding and interpreting the diverse and complex Indian demographic situation. The analysis of population geography in the Indian spatial, cultural, political, and historical context may be applied to other less developed countries of similar sociocultural background. The Indian Census has contributed over the 100 years of its existence reliable and efficiently produced data on a wide variety of measures at assorted scales down to the village level. Field work among geographers has not achieved a level of development commensurate with population censuses. Recent doctoral research has focused on qualitative studies of local situations. Research topics range from the distribution and structure of population, mortality, fertility, and migration to peripheral issues of social segregation. Popular topics include urbanization, labor force, sex composition, literacy, and population growth. Distribution of population and density studies have amounted to only 2 in 30 years.

    From the literature on error detection, the authors select several concepts relating error detection mechanisms and prospective memory features. They emphasize the central role of intention in the classification of the errors into slips/lapses/mistakes, in the error handling process and in the usual distinction between action-based and outcome-based detection. Intention is again a core concept in their investigation of prospective memory theory, where they point out the contribution of intention retrievals, intention persistence and output monitoring in the individual's possibilities for detecting their errors. The involvement of the frontal lobes in prospective memory and in error detection is also analysed. From the chronology of a prospective memory task, the authors finally suggest a model for error detection also accounting for neural mechanisms highlighted by studies on error-related brain activity.

    Bamboo shoots are considered as one of the useful health foods because of their rich contents of proteins, carbohydrates, vitamins, fibres, and minerals and very low fat. Though bamboo shoots provide lots of health benefits, their consumption is confined mostly to Southeast Asian and East Asian countries. The acceptability of bamboo shoots as popular vegetable crop is very less due to their high pungent smell and bitter acidic taste. The use of bamboo as food in India is mainly restricted to Northeastern part of the country where they form an indispensable part of several traditional speciality dishes. The different ethnic communities take fresh or fermented bamboo shoot as one of most preferred traditional food items. Some of the important bamboo based traditional foods are ushoi, soibum, rep, mesu, eup, ekhung, hirring, and so forth. Bamboo shoots should be properly processed before they are consumed as freshly harvested shoots have high content of toxic cyanogenic glycosides which may pose serious health problems. The prospect of bamboo shoot industry in Northeast India is bright due to its rich genetic resources of bamboos. However, habitat destruction and extensive use of bamboos for food, handicraft, and construction purposes have resulted in severe depletion of natural bamboo resources. This review stresses upon the high nutritive values and health benefits of bamboo shoots and their usage as important traditional foods in Northeast India. The bamboo market potential of the region and use of in vitro plant micropropagation methods as effective means of bamboo conservation are also emphasized in this paper.

    AIMS—To assess the long term results of intraocular lens (IOL) implantation for traumatic cataract in young children in a developing country.
METHODS—Prospective hospital based study of 52 children (age 2-10 years) undergoing unilateral cataract extraction and IOL insertion for traumatic cataract performed by a single surgeon in south India. Children were reviewed regularly and followed up initially for 3 years.
RESULTS—There were no serious operative complications. Clinically significant posterior capsule opacification was almost universal (92%) and YAG capsulotomy or membranectomy was performed on 48 eyes. Some degree of pupil capture affected 35% of eyes and was complete in 6%. Visual acuity was 6/12 or better in 67% of eyes at the last follow up examination.
CONCLUSION—The visual acuity results 3 years after implantation of posterior chamber IOLs in older children with traumatic cataracts in south India were encouraging. In developing countries where follow up is unreliable it is essential to plan to clear the axial part of the posterior capsule either at the time of surgery or soon afterwards.

    India's tourism industry generated 6.6% of the nation's Gross Domestic Product (GDP) during 2012. International travel to India is predicted to grow at an average annual rate of ∼ 8% over the next decade. The number of foreign tourists has increased by 9% to 5.8 million. Approximately 8% of travelers to developing countries require medical care during or after travel; the main diagnoses are vaccine-preventable diseases. Travelers to India can be exposed to various infectious diseases; water-borne, water-related, and zoonotic diseases may be imported to India where the disease is not endemic. The World Health Organization (WHO) emphasizes that all international travelers should be up to date with routine vaccinations. The recommended vaccinations for travelers to India vary according to the traveler's age, immunization history, existing medical conditions, duration, legal requirements for entry into countries being visited, travelers preferences, and values. Travelers should consult with a doctor so that there is sufficient time for completion of optimal vaccination schedules. No matter where traveling, one should be aware of potential exposure to certain organisms that can cause severely illnesses, even death. There is no doubt that vaccines have reduced or virtually eliminated many diseases that killed or severely disabled children and adults just a few generations ago. Thus, travelers must take recommended vaccines per schedule before traveling to India.

    India and Pakistan launched their respective nuclear programs in the 1940s and 1950s with considerable foreign technical support, especially from the United States Atoms for Peace Program. The technology and training that was acquired served as the platform for later nuclear weapon development efforts that included nuclear weapon testing in 1974 and in 1998 by India, and also in 1998 by Pakistan - which had illicitly acquired uranium enrichment technology especially from Europe and received assistance from China. As of 2013, both India and Pakistan were continuing to produce fissile material for weapons, in the case of India also for nuclear naval fuel, and were developing a diverse array of ballistic and cruise missiles. International efforts to restrain the South Asian nuclear build-up have been largely set aside over the past decade as Pakistani support became central for the U.S. war in Afghanistan and as U.S. geopolitical and economic interests in supporting the rise of India, in part as a counter to China, led to India being exempted both from U.S non-proliferation laws and international nuclear trade guidelines. In the absence of determined international action and with Pakistan blocking the start of talks on a fissile material cutoff treaty, nuclear weapon programs in South Asia are likely to keep growing for the foreseeable future.

    Vaccination is recommended throughout life to prevent infectious diseases and their sequelae. Vaccines are crucial to prevent mortality in that >25% of deaths are due to infections. Vaccines are recommended for adults on the basis of a range of factors. Substantial improvement and increases in adult vaccination are needed to reduce the health consequences of vaccine-preventable diseases among adults. Incomplete and inadequate immunization in India against these communicable diseases results in substantial and unnecessary costs both in terms of hospitalization and treatment. The government of India as well as the World Health Organization (WHO) consider childhood vaccination as the first priority, but there is not yet focus on adult immunization. Adult immunization in India is the most ignored part of heath care services. The Expert Group recommended that data on infectious diseases in India should be updated, refined, and reviewed periodically and published regularly. This group suggested that the consensus guidelines about adult immunization should be reviewed every 3 years to incorporate new strategies from any emerging research from India. There is an immediate need to address the problem of adult immunization in India. Although many issues revolving around efficacy, safety, and cost of introducing vaccines for adults at the national level are yet to be resolved, there is an urgent need to sensitize the health planners as well as health care providers regarding this pertinent issue.

International efforts to restrain the South Asian nuclear build-up have been largely set aside over the past decade as Pakistani support became central for the U.S. war in Afghanistan and as U.S. geopolitical and economic interests in supporting the rise of India, in part as a counter to China, led to India being exempted both from U.S non-proliferation laws and international nuclear trade guidelines. In the absence of determined international action and with Pakistan blocking the start of talks on a fissile material cutoff treaty, nuclear weapon programs in South Asia are likely to keep growing for the foreseeable future.

    Iodine deficiency disorders (IDD) constitute the single largest cause of preventable brain damage worldwide. Majority of consequences of IDD are invisible and irreversible but at the same time these are preventable. In India, the entire population is prone to IDD due to deficiency of iodine in the soil of the subcontinent and consequently the food derived from it. To combat the risk of IDD, salt is fortified with iodine. However, an estimated 350 million people do not consume adequately iodized salt and, therefore, are at risk for IDD. Of the 325 districts surveyed in India so far, 263 are IDD-endemic. The current household level iodized salt coverage in India is 91 per cent with 71 per cent households consuming adequately iodized salt. The IDD control goal in India was to reduce the prevalence of IDD below 10 per cent in the entire country by 2012. What is required is a “mission approach” with greater coordination amongst all stakeholders of IDD control efforts in India. Mainstreaming of IDD control in policy making, devising State specific action plans to control IDD, strict implementation of Food Safety and Standards (FSS) Act, 2006, addressing inequities in iodized salt coverage (rural-urban, socio-economic), providing iodized salt in Public Distribution System, strengthening monitoring and evaluation of IDD programme and ensuring sustainability of IDD control activities are essential to achieve sustainable elimination of IDD in India.

    Knowledge of the timing of India-Asia collision is a fundamental prerequisite for understanding the evolution of the Himalayan-Tibetan orogen and its role in global climate, oceanic chemistry, and ecological evolution. Despite much active research, the basic pre-collision tectonic configuration and the timing of terminal India-Asia suturing remain debated. For example, debates regarding when and how the intervening Kohistan-Ladakh arc was sutured with India and Asia still remain elusive; some models propose the arc collided with Asia at about 100 Ma, with India-Asia collision at ca. 55 Ma, whilst a newer model proposed the arc's collision with India at 50 Ma and subsequently with Asia at 40 Ma. Another example is the recent proposition that an oceanic Greater India Basin separated the Tethyan Himalaya microcontinent from the remaining Indian plate until 20- 25 Ma with the consumption of this oceanic basin marking the final collision at this time. These controversies relate to whether the commonly documented 50 Ma contact represents the terminal India-Asia suturing or the amalgamation between various arcs or microcontinents with India or Asia. Here we present an integrated provenance study of geochronology, thermochronology, and geochemistry on the late Cretaceous-Pleistocene sediments from the lower Indus basin on the Indian plate. The detrital zircon U-Pb and fission track data show a reversal in sediment source from a pure Indian signature to increasing inputs from the suture zone and the Asian plate between the middle Paleocene and early Oligocene. The Nd and Sr isotopes narrow down this change to 50 Ma by revealing input of Asian detritus and the establishment of a Nd & Sr isotopic pattern similar to the present-day Indus Fan by 50 Ma, with no significant variations up section, contrary to what might be expected if later major collisions had occurred. Our isotopic data indicate that Greater India was occupied by a fluvial-deltaic system, analogous to the

    The Kumta and Mercara suture zones welding together Archean crustal blocks in western peninsular India offer critical insights into Precambrian continental juxtapositions and the crustal evolution of eastern Gondwana. Here we present the results from an integrated study of the structure, geology, petrology, mineral chemistry, metamorphic P-T conditions, zircon U-Pb ages and Lu-Hf isotopes of metasedimentary rocks from the two sutures. The dominant rocks in the Kumta suture are greenschist- to amphibolite-facies quartz-phengite schist, garnet-biotite schist, chlorite schist, fuchsite schist and marble. The textural relations, mineral chemistry and thermodynamic modelling of garnet-biotite schist from the Kumta suture indicate peak metamorphic P-T conditions of ca. 11 kbar at 790 °C, with detrital SHRIMP U-Pb zircon ages ranging from 3420 to 2547 Ma, εHf (t) values from - 9.2 to 5.6, and TDMc model ages from 3747 to 2792 Ma. The K-Ar age of phengite from quartz-phengite schist is ca. 1326 Ma and that of biotite from garnet-biotite schist is ca. 1385 Ma, which are interpreted to broadly constrain the timing of metamorphism related to the suturing event. The Mercara suture contains amphibolite- to granulite-facies mylonitic quartzo-feldspathic gneiss, garnet-kyanite-sillimanite gneiss, garnet-biotite-kyanite-gedrite-cordierite gneiss, garnet-biotite-hornblende gneiss, calc-silicate granulite and metagabbro. The textural relations, mineral chemistry and thermodynamic modelling of garnet-biotite-kyanite-gedrite-cordierite gneiss from the Mercara suture indicate peak metamorphic P-T conditions of ca. 13 kbar at 825 °C, followed by isothermal decompression and cooling. For pelitic gneisses from the Mercara suture, LA-ICP-MS U-Pb zircon ages vary from 3249 to 3045 Ma, εHf (t) values range from - 18.9 to 4.2, and TDMc model ages vary from 4094 to 3314 Ma. The lower intercept age of detrital zircons in the pelitic gneisses from the Mercara suture ranges from 1464 to 1106

    Low-frequency electromagnetic (EM) signals are commonly used in geophysical exploration of the shallow subsurface. Sensitivity to conductivity implies they are particularly useful for inferring fluid content of porous media. However, low-frequency EM wavefields are diffusive, and have significantly larger wavelengths compared to seismic signals of equal frequency. The wavelength of a 30 Hz sinusoid propagating with seismic velocity 3000 m/s is 100 m, whereas an analogous EM signal diffusing through a conductive body of 0.1 S/m (clayey shale) has wavelength 1825 m. The larger wavelength has implications for resolution of the EM prospecting method. We are investigating resolving power of the EM method via theoretical and numerical experiments. Normal incidence plane wave reflection/transmission by a thin geologic bed is amenable to analytic solution. Responses are calculated for beds that are conductive or resistive relative to the host rock. Preliminary results indicate the classic seismic resolution/detection limit of bed thickness ~1/8 wavelength is not achieved. EM responses for point or line current sources recorded by general acquisition geometries are calculated with a 3D finite-difference algorithm. These exhibit greater variability which may allow inference of bed thickness. We also examine composite responses of two point scatterers with separation when illuminated by an incident EM field. This is analogous to the Rayleigh resolution problem of estimating angular separation between two light sources. The First Born Approximation implies that perturbations in permittivity, permeability, and conductivity have different scattering patterns, which may be indicators of EM medium properties.

  16. 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

    This is a prospective longitudinal descriptive study to prospectively evaluate quality of life (QoL) in the spinal cord injury (SCI) population in Northern India and identify any association between clinical variables and QoL; and, finally, to see the impact of remedial measures taken to improve QoL over time. Fifty persons with SCI were surveyed for medical problems, neurological status and social adjustments in Northern India. QoL was determined on the Global QoL scale (Visual Analogue Scale) and follow-up assessment was performed 6 months later to examine the impact of remedial measures over time. Thirty-six (72%) men and 14 (28%) women participated. Mean age and duration of injury were 37.7 and 3.7 years, respectively. Bladder problems (44%), bedsores (36%), gastrointestinal problems (56%), neuropathic pain (42%) and spasticity (60%) were the most common medical problems. Age, education, marital status and duration of injury were not associated with significant difference on QoL scores. Female sex, employment, mobility, autonomy, cordial partner relations and good social adjustment were associated with higher scores of QoL. Mean Global QoL scores were 54.3 and 63.7 at the initial survey and at the 6-month follow-up survey, respectively. In a community-based sample of SCI in Northern India, a good-to-fair QoL was found. It is reasonable to believe that understanding and taking appropriate remedial measures through more comprehensive rehabilitation programmes will play a vital role in enhancement of QoL in persons with SCI.

    It is 60years since the discovery of the correct number of chromosomes in 1956; the field of cytogenetics had evolved. The late evolution of this field with respect to other fields is primarily due to the underdevelopment of lenses and imaging techniques. With the advent of the new technologies, especially automation and evolution of advanced compound microscopes, cytogenetics drastically leaped further to greater heights. This review describes the historic events that had led to the development of human cytogenetics with a special attention about the history of cytogenetics in India, its present status, and future. Apparently, this review provides a brief account into the insights of the early laboratory establishments, funding, and the German collaborations. The details of the Indian cytogeneticists establishing their labs, promoting the field, and offering the chromosomal diagnostic services are described. The detailed study of chromosomes helps in increasing the knowledge of the chromosome structure and function. The delineation of the chromosomal rearrangements using cytogenetics and molecular cytogenetic techniques pays way in identifying the molecular mechanisms involved in the chromosomal rearrangement. Although molecular cytogenetics is greatly developing, the conventional cytogenetics still remains the gold standard in the diagnosis of various numerical chromosomal aberrations and a few structural aberrations. The history of cytogenetics and its importance even in the era of molecular cytogenetics are discussed.

    The Perth Abyssal Plain (PAP) formed at the nexus of rifting and breakup between three major continents within Gondwana - India, Australia and Antarctica. Oceanic crust within the PAP records the history of Mesozoic seafloor spreading as India moved away from Australia. However, despite the clear importance of the seafloor spreading history of the PAP in constraining the relative motions of these continents during the early stages of breakup, little attention has been paid to the PAP, and particularly its western flank largely due to a lack of new data in collected in this region. We present new observations to constrain the evolution of the PAP, collected during voyage ss2011/v06 of the Southern Surveyor in late 2011. The new data comprise magnetic anomaly profile data, swath bathymetry, and dredge samples collected from 7 sites. The most significant dredge results were obtained from the Batavia Knoll (BK) and Gulden Draak Knoll (GDK), two prominent bathymetric features located >1000 km west of the Australian continental margin. Previous tectonic reconstructions typically treat these bathymetric features as igneous plateaus emplaced on older oceanic crust. However, dredges carried out on the western flanks of each of these knolls recovered continental basement rocks, revealing that both knolls are continental fragments. Estimates of the depths to magnetic sources for shiptrack profiles across the knolls provide evidence for variations in sediment thickness within the knolls. We use forward modeling of shiptrack magnetic profiles combined with gravity anomalies derived from satellite altimetry to make first-order estimates of the extent and spatial variation in thickness of the continental crust. New magnetic anomaly profiles provide evidence for previously unidentified M-series anomalies in the western part of the Perth Abyssal Plain, east of the BK and GDK. These observations both support a reconstruction model in which the microcontinents rifted away from

    2015-01-01

    Background: Nonoccupational anthracosis and silicosis has been reported from various parts of the world including Ladakh in Jammu and Kashmir, India; however, anthracosilicosis has only been reported in industrial workers till date. Materials and Methods: Six cases from the Ladakh region in Jammu and Kashmir, India with similar clinico-radiological-pathological features, i.e., anthracosilicosis/anthracofibrosis have been analyzed. Of these, four were analyzed retrospectively and two prospectively. Result: All the patients were homemakers and resided in Ladakh in Jammu and Kashmir, India since birth with an age range of 42–62 years and an average age of 56 years. Their average duration of symptoms was 4 years. Spirometry showed small and/or large airway disease in 5/6 cases. On computed tomography (CT), 4/6 cases showed progressive massive fibrosis (PMF) with calcified mediastinal lymph nodes. There were random or centrilobular nodules in all the six cases. Bronchoscopy in 5/6 cases showed multiple anthracotic pigments with narrowing and distortion of the bronchus (anthracofibrosis). Malignancy was suspected clinico-radiologically in four cases and pathologically in two cases. On histopathology, anthracosis was demonstrated in all and silicosis in three cases. Conclusion: Anthracosilicosis can occur due to environmental exposure. Ladakh in Jammu and Kashmir, India is the only place across the globe with unique environmental features having the presence of both free silica and biomass fuel. The disease was observed predominantly in older women. Awareness would prevent unnecessary investigation for malignancy. Treatment with the bronchodilator is useful as it has evidence of airway disease. Finally, environmental measures and a proper study need to be undertaken for knowing the relative role of silica versus soot in causing the lung disease and preventing this irreversible condition.

    2014-01-01

    Background and Objectives It would be of considerable interest to clinicians if the burden of chronic pulmonary aspergillosis (CPA) and allergic bronchopulmonary aspergillosis (ABPA) in India were known. Herein, we estimate the burden of CPA following pulmonary tuberculosis (PTB), and ABPA (and severe asthma with fungal sensitization [SAFS]) complicating asthma. Methods We used the population estimates for India from the 2011 census data. The burden of asthma was estimated using three different methods (Global Initiative against Asthma [GINA] report statement, World Health Survey [WHS] estimates, Indian study on the epidemiology of asthma and chronic bronchitis [INSEARCH]). Global and India-specific figures were used for calculating the prevalence of ABPA and SAFS. The World Health Organization estimates were used for calculating PTB rates while the frequency of CPA was assessed from a previously published scoping review. Sensitivity analysis was performed to determine the burden in various scenarios. Results The total Indian population in 2011 was 1.2 billion. The asthma prevalence in adults was estimated at about 27.6 (range, 17–30) million. The burden of ABPA ranged from 0.12–6.09 million with different assumptions (best estimate, 1.38 [range, 0.86–1.52] million). The prevalence of SAFS was approximated at about 0.52–1.21 million (best estimate, 0.96 [range, 0.6–1.06] million). The incident TB cases were about 2.1 million while the annual incidence of CPA varied 27,000-0.17 million cases, with different estimates. If the mortality of CPA is estimated as 15% annually, the 5-year prevalence of CPA was placed at 290,147 cases with 5-year prevalence rate being 24 per 100,000. Conclusion There is a significant burden of ABPA, SAFS and CPA in India. Prospective community-based studies are required to accurately determine the prevalence of these disorders. PMID:25478929

    Successive Governments of India have promised to transform India's unsatisfactory health-care system, culminating in the present government's promise to expand health assurance for all. Despite substantial improvements in some health indicators in the past decade, India contributes disproportionately to the global burden of disease, with health indicators that compare unfavourably with other middle-income countries and India's regional neighbours. Large health disparities between states, between rural and urban populations, and across social classes persist. A large proportion of the population is impoverished because of high out-of-pocket health-care expenditures and suffers the adverse consequences of poor quality of care. Here we make the case not only for more resources but for a radically new architecture for India's health-care system. India needs to adopt an integrated national health-care system built around a strong public primary care system with a clearly articulated supportive role for the private and indigenous sectors. This system must address acute as well as chronic health-care needs, offer choice of care that is rational, accessible, and of good quality, support cashless service at point of delivery, and ensure accountability through governance by a robust regulatory framework. In the process, several major challenges will need to be confronted, most notably the very low levels of public expenditure; the poor regulation, rapid commercialisation of and corruption in health care; and the fragmentation of governance of health care. Most importantly, assuring universal health coverage will require the explicit acknowledgment, by government and civil society, of health care as a public good on par with education. Only a radical restructuring of the health-care system that promotes health equity and eliminates impoverishment due to out-of-pocket expenditures will assure health for all Indians by 2022--a fitting way to mark the 75th year of India

National cancer registry program of the Indian Council of Medical Research (ICMR) has been recently expanded to include 21 population based and 6 hospital based cancer registries. The last published registry data by ICMR available in the cancer registry website (www.ncrpindia.org) was in 2008 which provides information on various cancers from 2006 to 2008. The other source of information was the report published by International Agency for Research on Cancer (WHO). According to these available data the age adjusted incidence rate of hepatocellular carcinoma (HCC) in India for men ranges from 0.7 to 7.5 and for women 0.2 to 2.2 per 100,000 population per year. The male:female ratio for HCC in India is 4:1. The age of presentation varies from 40 to 70 years. According to a study conducted by verbal autopsy in 1.1 million homes representing the whole country, the age standardized mortality rate for HCC in India for men is 6.8/100,000 and for women is 5.1/100,000. According to another study the incidence of HCC in cirrhotics in India is 1.6% per year. The unpublished data from various tertiary care centers suggest that the incidence of HCC is increasing in India. There is a need for a multi-centric HCC registry under the aegis of INASL.

    One of the major challenges we face on our planet is increasing agricultural production to meet the dietary requirements of an additional 2.5 billion people by the mid of the century while limiting cropland expansion and other damages to natural resources. This problem is even more so challenging given that nearly all the population growth will take place where the majority of the hungry live today and where ongoing and future climate changes are projected to most negatively impact agricultural production, the semi-arid tropics (SAT). The SAT contain 40% of the global irrigated and rainfed croplands in over 50 developing countries and a growing population of over a billion and half people, many of which live in absolute poverty and strongly depend on agriculture that is constrained by chronic water shortages. Rates of food grain production in many of the countries of the SAT have progressively increased since the mid 1960s aided by the Green Revolution and relatively favourable climatic conditions. However, aggregated agricultural production statistics indicate that the rate of food grain production has recently stalled or declined in several of the countries in this region, escalating the concerns over matters of food security, that is availability of food and one’s access to it, in a region where many people live in extreme poverty, depend on an agrarian economy and are expected to face increasingly worse climatic conditions in the near future. In this paper we analyze the agricultural deceleration and its drivers over the country of India, which faces the daunting challenge of needing a 50-100% increase in yields of major crops by the middle to the 21st century to feed its growing population. We analyze the long term (1982-2006) record of the Normalized Difference Vegetation Index (NDVI) from the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer (NOAA/AVHRR) together with climate, land use, and crop production

    It goes without saying that insects epitomize diversity, and with over a million documented species they stand out as one of the most remarkable lineages in the 3.5-billion-year history of life on earth (Figure 1). This reality is passé to even the layperson and is taken for granted in the same way none of us think much of our breathing as we go about our day, and yet insects are just as vital to our existence. Insects are simultaneously familiar and foreign to us, and while a small fraction are beloved or reviled, most are simply ignored. These inexorable evolutionary overachievers outnumber us all, their segmented body plan is remarkably labile, they combine a capacity for high rates of speciation with low levels of natural extinction, and their history of successes eclipses those of the more familiar ages of dinosaurs and mammals alike. It is their evolution - persisting over vast expanses of geological time and inextricably implicated in the diversification of other lineages - that stands as one of the most expansive subjects in biology.

  14. Fungal weathering of asbestos in semi arid regions of India.

    The science of Geomicrobiology, which deals with mineral- microbe interaction in nature contributes effectively to three important processes namely- mineral and metal bioremediation, biomining and soil mineral formation by microbes. Bioremediation one of the important process of the above, degrades or transforms hazardous contaminants to less toxic compounds. Several groups of fungi have proved highly efficient in this aspect, with asbestos being one such toxic entity in the environment on which their activity was studied. The present investigation uses the same tool as a device for detoxifying asbestos, a potent carcinogenic entity; with fungal isolates native to the asbestos mines of Rajasthan, India, being investigated for the first time. The cellular mechanism of asbestos toxicity is mainly attributed to the presence of iron in its chemical composition which catalyzes generation of free radicals leading to oxidation of biomolecules. The two dominant novel species found therein, identified as Aspergillus tubingenesis and Coemansia reversa have proved capable of actively removing iron from asbestos fibers as studied by scanning electron microscopy- electron diffraction X-ray (SEM-EDX) analysis. This probably could lead to a reduction in toxicity of asbestos, due to reduced iron concentration as reported in related studies. Many fungi are known to release iron chelating compounds, siderophores, which could be instrumental in the study. The findings related to two new fungal species being added to the list of earlier identified fungal bioremediators of asbestos, widens the prospect of using bioremediation as an effective tool for asbestos detoxification.

    Public Health Management has taken a momentous leap and seeks to provide a plausible answer to many issues related to public health. A key area identified to aid the public health objectives in the country is human resource management. The country faces a dire crunch in the available work force in almost all the healthcare network. Countering the current health situation in the country, various institutes have come up offering specialized courses in public health management. The wide gap between supply and demand for trained health care managers/ administrators to work for hospitals, pharmaceutical companies, health insurance and third party administration and other health care provider organizations needs attention. The paper is a situational analysis of all such courses offered pan India. A systematic, predefined approach was used to collect and assemble the data. All the institutes offering such courses were contacted for detailed information. Fifty one institutes have been identified which annually produce around 2122 qualified professional to work in the domain of public health management. The paper also discusses the demand analysis where these prospective students can be placed. An estimated 19,930 professionals would be required based upon the country's present status, which reflects the dearth in their workforce capacity. The paper also enlighten the scope of strengthening the existing system, by effectively training the existing workforce for their capacity building, and highlights training opportunities for working professional to pursue a related academic program.

    Historically, malaria in India was predominantly caused by Plasmodium vivax, accounting for 53% of the estimated cases. After the spread of drug-resistant Plasmodium falciparum in the 1990s, the prevalence of the two species remained equivalent at the national level for a decade. By 2014, the proportion of P. vivax has decreased to 34% nationally, but with high regional variation. In 2014, P. vivax accounted for around 380,000 malaria cases in India; almost a sixth of all P. vivax cases reported globally. Plasmodium vivax has remained resistant to control measures, particularly in urban areas. Urban malaria is predominantly caused by P. vivax and is subject to outbreaks, often associated with increased mortality, and triggered by bursts of migration and construction. The epidemiology of P. vivax varies substantially within India, including multiple relapse phenotypes with varying latencies between primary infection and relapse. Moreover, the hypnozoite reservoir maintains transmission potential and enables reestablishment of the parasite in areas in which it was thought eradicated. The burden of malaria in India is complex because of the highly variable malaria eco-epidemiological profiles, transmission factors, and the presence of multiple Plasmodium species and Anopheles vectors. This review of P. vivax malaria in India describes epidemiological trends with particular attention to four states: Gujarat, Karnataka, Haryana, and Odisha.

    All previously obtained wolf (Canis lupus) and dog (Canis familiaris) mitochondrial (mt) DNA sequences fall within an intertwined and shallow clade (the 'wolf-dog' clade). We sequenced mtDNA of recent and historical samples from 45 wolves from throughout lowland peninsular India and 23 wolves from the Himalayas and Tibetan Plateau and compared these sequences with all available wolf and dog sequences. All 45 lowland Indian wolves have one of four closely related haplotypes that form a well-supported, divergent sister lineage to the wolf-dog clade. This unique lineage may have been independent for more than 400,000 years. Although seven Himalayan wolves from western and central Kashmir fall within the widespread wolf-dog clade, one from Ladakh in eastern Kashmir, nine from Himachal Pradesh, four from Nepal and two from Tibet form a very different basal clade. This lineage contains five related haplotypes that probably diverged from other canids more than 800,000 years ago, but we find no evidence of current barriers to admixture. Thus, the Indian subcontinent has three divergent, ancient and apparently parapatric mtDNA lineages within the morphologically delineated wolf. No haplotypes of either novel lineage are found within a sample of 37 Indian (or other) dogs. Thus, we find no evidence that these two taxa played a part in the domestication of canids.

    2012-01-01

    Diverse structural, functional and valuable polysaccharides are synthesized by bacteria of all taxa and secreted into the external environment. These polysaccharides are referred to as exopolysaccharides and they may either be homopolymeric or heteropolymeric in composition and of diverse high molecular weights (10 to 1000 kDa). The material properties of exopolysaccharides have revolutionized the industrial and medical sectors due to their retinue of functional applications and prospects. These applications have been extensive in areas such as pharmacological, nutraceutical, functional food, cosmeceutical, herbicides and insecticides among others, while prospects includes uses as anticoagulant, antithrombotic, immunomodulation, anticancer and as bioflocculants. Due to the extensive applications of bacterial exopolysaccharides, this overview provides basic information on their physiologic and morphologic functions as well as their applications and prospects in the medical and industrial sectors.

    Physical inactivity is the fourth leading risk factor for global mortality, with most of these deaths occurring in low and middle-income countries (LMICs) like India. Research from developed countries has consistently demonstrated associations between built environment features and physical activity levels of populations. The development of culturally sensitive and reliable measures of the built environment is a necessary first step for accurate analysis of environmental correlates of physical activity in LMICs. This study systematically adapted the Neighborhood Environment Walkability Scale (NEWS) for India and evaluated aspects of test-retest reliability of the adapted version among Indian adults. Cultural adaptation of the NEWS was conducted by Indian and international experts. Semi-structured interviews were conducted with local residents and key informants in the city of Chennai, India. At baseline, participants (N = 370; female = 47.2%) from Chennai completed the adapted NEWS-India surveys on perceived residential density, land use mix-diversity, land use mix-access, street connectivity, infrastructure and safety for walking and cycling, aesthetics, traffic safety, and safety from crime. NEWS-India was administered for a second time to consenting participants (N = 62; female = 53.2%) with a gap of 2-3 weeks between successive administrations. Qualitative findings demonstrated that built environment barriers and constraints to active commuting and physical activity behaviors intersected with social ecological systems. The adapted NEWS subscales had moderate to high test-retest reliability (ICC range 0.48-0.99). The NEWS-India demonstrated acceptable measurement properties among Indian adults and may be a useful tool for evaluation of built environment attributes in India. Further adaptation and evaluation in rural and suburban settings in India is essential to create a version that could be used throughout India.

    Many enzymes are efficiently produced by microbes. However, the use of natural enzymes as biocatalysts has limitations such as low catalytic efficiency, low activity, and low stability, especially under industrial conditions. Many protein engineering technologies have been developed to modify natural enzymes and eliminate these limitations. Commonly used protein engineering strategies include directed evolution, site-directed mutagenesis, truncation, and terminal fusion. This review summarizes recent advances in the molecular engineering of industrial enzymes and discusses future prospects in this field. We expect this review to increase interest in and advance the molecular engineering of industrial enzymes.

    1999-07-01

    This paper reports on an analysis of productivity growth and input trends in six energy intensive sectors of the Indian economy, using growth accounting and econometric methods. The econometric work estimates rates and factor price biases of technological change using a translog production model with an explicit relationship defined for technological change. Estimates of own-price responses indicate that raising energy prices would be an effective carbon abatement policy for India. At the same time, the authors results suggest that, as with previous findings on the US economy, such policies in India could have negative long run effects on productivity in these sectors. Inter-input substitution possibilities are relatively weak, so that such policies might have negative short and medium term effects on sectoral growth. The authors study provides information relevant for the analysis of costs and benefits of carbon abatement policies applied to India and thus contributes to the emerging body of modeling and analysis of global climate policy.

    India is known for its vast human diversity, consisting of more than four and a half thousand anthropologically well-defined populations. Each population differs in terms of language, culture, physical features and, most importantly, genetic architecture. The size of populations varies from a few hundred to millions. Based on the social structure, Indians are classified into various caste, tribe and religious groups. These social classifications are very rigid and have remained undisturbed by emerging urbanisation and cultural changes. The variable social customs, strict endogamy marriage practices, long-term isolation and evolutionary forces have added immensely to the diversification of the Indian populations. These factors have also led to these populations acquiring a set of Indian-specific genetic variations responsible for various diseases in India. Interestingly, most of these variations are absent outside the Indian subcontinent. Thus, this review is focused on the peopling of India, the caste system, marriage practice and the resulting health and forensic implications.

    2003-01-01

    In India, locally mined asbestos is not enough for its current needs, hence a great deal of asbestos is imported from Canada. Asbestos products manufacturers have prevailed upon the government to reduce tariffs on imported material. The efforts of the health and safety professionals who joined with nongovernmental organizations to form the Ban Asbestos Network of India (BANI) are being consistently sabotaged by the industry, using its influence and false propaganda that chrysotile asbestos can be safely used in a controlled manner. Weak legislation and lack of data are being exploited by the industry to convince policymakers that asbestos use in India has caused no major health problems. Despite this, the ban-asbestos movement has gained momentum and was able to persuade government to consider banning asbestos use. With the growing strength of the movement it is expected that asbestos manufacturers may find it increasingly difficult to manipulate the government in the future.

    The rapid growth in motor vehicle activity in India and other rapidly industrializing low-income countries is contributing to high levels of urban air pollution, among other adverse socioeconomic, environmental, health, and welfare impacts. This paper first discusses the local, regional, and global impacts associated with air pollutant emissions resulting from motor vehicle activity, and the technological, behavioral, and institutional factors that have contributed to these emissions, in India. The paper then discusses some implementation issues related to various policy measures that have been undertaken, and the challenges of the policy context. Finally, the paper presents insights and lessons based on the recent Indian experience, for better understanding and more effectively addressing the transport air pollution problem in India and similar countries, in a way that is sensitive to their needs, capabilities, and constraints.

    applicability of cultivation methods for detection of microorganisms in the presence of low-molecular-weight compounds with the cu-mulative function and adaptogenic properties. -During the germination of surviving cells, "stress induced by the new environment and changes in the physiological status" is observed, which requires soft conditions and the use of stress protector and antioxidants. -The virulence and pathogenicity of microorganisms develop and manifest only as a result of the long-term co-evolution of microorganisms and host macroorganisms, or bacteriophages and host microor-ganisms. No mutations of an admittedly nonpathogenic microorganism, and in the absence of a potential victim of the disease, can make this microorganism pathogenic. To detect microbial cells by direct methods, we may recommend to take the following aspects into consideration: -characteristic traits of the ultrastructure of surviving (resting) cells; -characteristic profiles of biogenic elements, which distinguish cells from biomorphs; -specific dyes. Deactivation of microorganisms in accordance with the quarantine requirements may be achieved via the use of an original technique of "cell mummification". This technique works well with the methods used to solve the above-stated problems. A mummified cell (micromummy) retains its morpho-logical intactness and characteristic ultrastructure (except for the membrane structure), which allows us to identify this cell as a microorganism (microbial cell).

    To assess Indias recent trends in child mortality rates and disparities and identify ways to reduce child mortality and wealth-related health disparities, we analyzed three years of data from Indias National Family Health Survey related to child mortality. Nationally, declines in average child mortality were statistically significant, but declines in inequality were not. Urban areas had lower child mortality rates than rural areas but higher inequalities. Interstate differences in child mortality rates were significant, with rates in the highest-mortality states four to six times higher than in the lowest-mortality states. However, child mortality in most states declined.

  20. Charnockitic magmatism in southern India

    Rajesh, H. M.; Santosh, M.

    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.

  5. Scientific knowledge and modern prospecting

    USGS Publications Warehouse

    Neuerburg, G.J.

    1985-01-01

    Modern prospecting is the systematic search for specified and generally ill-exposed components of the Earth's crust known as ore. This prospecting depends entirely on reliable, or scientific knowledge for guidance and for recognition of the search objects. Improvement in prospecting results from additions and refinements to scientific knowledge. Scientific knowledge is an ordered distillation of observations too numerous and too complex in themselves for easy understanding and for effective management. The ordering of these observations is accomplished by an evolutionary hierarchy of abstractions. These abstractions employ simplified descriptions consisting of characterization by selected properties, sampling to represent much larger parts of a phenomenon, generalized mappings of patterns of geometrical and numerical relations among properties, and explanation (theory) of these patterns as functional relations among the selected properties. Each abstraction is predicated on the mode of abstraction anticipated for the next higher level, so that research is a deductive process in which the highest level, theory, is indispensible for the growth and refinement of scientific knowledge, and therefore of prospecting methodology. ?? 1985 Springer-Verlag.

    Tremendous global efforts have been made to collect data on the HIV/AIDS epidemic. Yet, significant challenges remain for generating and analysing evidence to allocate resources efficiently and implement an effective AIDS response. India offers important lessons and a model for intelligent and integrated use of data on HIV/AIDS for an evidence-based response. Over the past 15 years, the number of data sources has expanded and the geographical unit of data generation, analysis and use for planning has shifted from the national to the state, district and now subdistrict level. The authors describe and critically analyse the evolution of data sets in India and how they have been utilised to better understand the epidemic, advance policy, and plan and implement an increasingly effective, well-targeted and decentralised national response to HIV and AIDS. The authors argue that India is an example of how ‘know your epidemic, know your response’ message can effectively be implemented at scale and presents important lessons to help other countries design their evidence generation systems.

  13. Liberalising trade in health services: constraints and prospects for South Asian countries.

    PubMed

    Khatun, Fahmida; Ahamad, Mazbahul

    2015-01-01

    This paper attempts to examine the prospects and challenges associated with liberalising trade in health services in five South Asian countries, namely Bangladesh, India, Nepal, Pakistan and Sri Lanka. Country-specific secondary information, a brief literature review of empirical studies and debriefing sessions with key stakeholders are employed to explore the issues related to liberalising health services trade. The health sectors in India, Nepal and Pakistan are scheduled under General Agreement on Trade in Services (GATS) classification, whereas those in Bangladesh and Sri Lanka are not. In Bangladesh, there is opportunity for investment in joint venture hospitals under Mode 3. Nonetheless, India is the largest trader in health services under all four modes. In Sri Lanka, cross-border trade in healthcare services is found to be insignificant. Moreover, expertise in eye treatment in Nepal could also attract foreign investment in medical services under Mode 3. In contrast, Pakistan exhibits no potential under Mode 4, because of a lack of healthcare professionals. In this view, the prospects of trade in health services within the South Asian region under the four GATS modes are constrained by infrastructural, regulatory, perception-related, logistical and cultural problems. Considering the level of development and commercial opportunities, regional integration in the health sector could be explored in such areas as telemedicine, medical tourism, cross-border investment and capacity building of health personnel. These developments call for stronger and pro-active government-to-government collaboration in the South Asian Association of Regional Cooperation (SAARC) region in a transparent and accountable manner.

    The canine parvovirus (CPV) infection is a highly contagious and serious enteric disease of dogs with high fatality rate. The present study was taken up to characterize the full-length viral polypeptide 2 (VP2) gene of CPV of Indian origin along with the commercially available vaccines. The faecal samples from parvovirus suspected dogs were collected from various states of India for screening by PCR assay and 66.29% of samples were found positive. Six CPV-2a, three CPV-2b, and one CPV-2c types were identified by sequence analysis. Several unique and existing mutations have been noticed in CPV types analyzed indicating emergence of newer variants of CPV in India. The phylogenetic analysis revealed that all the field CPV types were grouped in different subclades within two main clades, but away from the commercial vaccine strains. CPV-2b and CPV-2c types with unique mutations were found to be establishing in India apart from the prevailing CPV-2a type. Mutations and the positive selection of the mutants were found to be the major mechanism of emergence and evolution of parvovirus. Therefore, the incorporation of local strain in the vaccine formulation may be considered for effective control of CPV infections in India.

    Linux operating system (LOS) is a sophisticated man-made system and one of the most ubiquitous operating systems. However, there is little research on the structure and functionality evolution of LOS from the prospective of networks. In this paper, we investigate the evolution of the LOS network. 62 major releases of LOS ranging from versions 1.0 to 4.1 are modeled as directed networks in which functions are denoted by nodes and function calls are denoted by edges. It is found that the size of the LOS network grows almost linearly, while clustering coefficient monotonically decays. The degree distributions are almost the same: the out-degree follows an exponential distribution while both in-degree and undirected degree follow power-law distributions. We further explore the functionality evolution of the LOS network. It is observed that the evolution of functional modules is shown as a sequence of seven events (changes) succeeding each other, including continuing, growth, contraction, birth, splitting, death and merging events. By means of a statistical analysis of these events in the top 4 largest components (i.e., arch, drivers, fs and net), it is shown that continuing, growth and contraction events occupy more than 95% events. Our work exemplifies a better understanding and describing of the dynamics of LOS evolution.

    Isolation of Leptospira from the kidneys of Rattus rattus wroughtoni hinton, Rattus rattus rufescens, Bandicota bengalensis and Bandicota indica was attempted in Bangalore in southern India. In total, 296 spirochaetes were isolated from 1,348 kidney cultures (an isolation rate of 22%). A batch of fifty-six isolates from India was identified, based on serological and polymerase chain reaction analysis, of which twenty-three isolates were identified as L. inadai by the World Health Organization/Food and Agriculture Organization Collaborating Centre for Reference and Research on Leptospirosis, in Brisbane. This is the first record of isolation of L. inadai from rodents. The preponderance of L. inadai in four different species of rodents suggests that these animals could be the natural reservoir hosts of L. inadai, and raises a critical question as to the likely impact of this species of Leptospira on the renal carrier status of other Leptospira pathogenic to humans and animals in this part of India. Virulence studies conducted at the University of Trieste in Italy, revealed that isolates of L. inadai from India were moderately or totally serum resistant when subjected to a serum killing test. To establish the possible seroprevalence of this species in the population, the inclusion of L. inadai in the battery of leptospiral antigens used for sero-epidemiological studies is recommended.

  6. The enchantment of science in India.

    PubMed

    Kapila, Shruti

    2010-03-01

    In critiquing methodologies of the "global" as a spatial unit of analysis or a receptacle for influence across the planet, this essay positions India so as to assess the role and forms of science in the modern world. By taking the mid-nineteenth century as a moment of departure, it asks why, under what conditions, and to what effects Indians accepted science, but not biomedicine, in the high noon of colonialism. Existing imperial histories of science that are primarily fixated on the eighteenth century cast science as a site of exchange and dialogue, thus replicating the narrative of European expansion overseas. Instead, the power of science is here understood in the context of the politics of religion and rationality. In a synoptic overview, the essay assesses the archaeology of science and the blurred practices between religion and science, described here as "insurgent." It argues that science in India was a form of enchantment, while religion had become a form of disenchanted but rational knowledge. Unlike in Europe, and contrary to orientalist positions, science in India neither declared the death of God nor became "spiritualized" via religion. Instead, science inflected religion; and religion, in turn, facilitated a rational mediation between science and man. This specific relationship accounts for the "soft landing" of science in India and its usurpation in the service of an unapologetic national modernity.

    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.

    2014-01-01

    India lacks a national policy on the prevention and control of genetic disorders. Although the haemoglobinopathies have received some attention, there are scarce data on the epidemiology of other genetic disorders in India. Haemophilia, an inherited single gene disorder with an incidence of 1 per 10,000 births, manifests as spontaneous or trauma-induced haemorrhagic episodes in patients, progressing to chronic disability and premature mortality in untreated patients or patients with sub-optimal treatment. Although the genetic basis of this disorder has been well studied in India, data on the number of patients, trends of the disorder in India, social costs of the condition and opportunities and competencies for offering genetic counselling through a public health programme have not been reported. This review article summarizes the available Indian data, which show that the country harbours the second highest number of global patients with haemophilia A. The reported number of patients with haemophilia A is 11,586 while the estimated prevalence could be around 50,000 patients. This review also identifies the need to immediately initiate a national programme for haemophilia, with components of prevention, care for patients, surveillance and education and support for families.

    2009-10-01

    This study focuses on describing full spectrum of clinical, laboratory, and radiological characterization of ankylosing spondylitis (AS) patients in India. Data on 70 consecutive AS patients, seen at the rheumatology clinic in India, was prospectively obtained using investigator-administered questionnaires. Diagnosis was made according to the modified New York criteria. The core set of variables selected by Assessment in AS International society were obtained. The differences in clinical characteristics based on presence or absence of peripheral arthritis, gender, and juvenile (JOAS) vs. adult onset AS (AOAS) were evaluated. The male/female ratio was 5:1. The mean age of onset of symptoms and diagnosis were 23.6 and 32.5 years, respectively. Females had similar spinal indices and radiological damage as male counterpart. However, they had more common extra-articular manifestations and root joint involvement. The majority of patients consisted of AOAS (78.5%) and was clinically similar to JOAS. One or more peripheral joints were involved in 65.7% of patients, affecting predominantly the lower extremity (90.6%, knee 47.1%, and ankle 35.7%) in asymmetrical pattern (78%). Patients with peripheral arthritis had higher erythrocyte sedimentation rate, more frequent enthesitis, root joint, and whole spine involvement, suggesting more aggressive disease. Most common site of enthesitis was chondro-sternal junction (30%) and Achilles tendonitis (24.3%). The root joints frequently involved extra-axial joints. Uveitis was the most common extra-articular manifestation (25.7%). The predominant initial symptom was typical inflammatory low back pain (87.1%). Assessment in ankylosing spondylitis indices showed a moderately severe disease activity and damage with following values: mean Bath Ankylosing Spondylitis Disease Activity Index, 3.2 (+/-1.8); mean Bath Ankylosing Spondylitis Functional Index, 2.3 (+/-2.0); and mean Bath Ankylosing Spondylitis Metrology Index, 3.15 (+/-2

The population was 685.2 million in 1981 and is projected to increase to 996.0 million in 2001. The growth rate is expected to decline to 2% during 1981-91 and to 1.6% from 1991-2001. Life expectancy at birth in 1980 was estimated at 54.1 for males and 54.7 for females. The national health policy envisages health as a vital component of overall integrated socioeconomic development but emphasizes the need to ensure adequate nutrition, safe drinking water and improved sanitation. The family welfare program is voluntary and involves intensive efforts to create awareness of population through multimedia and interpersonal channels and to provide a wide choice of contraceptives for eligible couples. Emphasis has been placed on increasing female literacy and on population education for youth. The goal is a net reproduction rate of 1 by the year 2000. Currently 40 million of the 126 million reproductive aged couples use an effective method of birth control. Sterilization continues to be an important method, but emphasis on spacing methods began at the outset of the 6th 5-year plan in 1980 and will continue during the 7th 5-year plan. Adequate training will be provided for rural health workers as part of the strategy to lower birth rates. The urban family welfare infrastructure will be strengthened to cover low-income population groups, and the mass media infrastructure is being restructured and strengthened. Efforts are underway to encourage participation in family planning by voluntary organizations. The medical education curriculum is undergoing revision to introduce formal family planning training. It is expected that the combined impact of improvement in social and economic living conditions and the national program

    Quitline activity in Rajasthan, India is a voluntary activity of Rajasthan Cancer Foundation (RCF) since April 2013. To kick-off, it took the benefit of the State Government- PIRAMAL SWASTHYA (PS)1 collaborative 104 Health Information Helpline that existed already in public-private partnership. It is a reactive quitline that helps callers through the counselors and nursing staff trained specifically through the weekly sessions held by the first author, the RCF resource on quitline. Besides structuring of the scripts for primary intervention and follow-ups after 1 week, 1 month, 6 months and a year, he also monitors calls, advices and coordinates with the supervisors to manage and analyze the data base, and reports to the PS lead at the Jaipur Center on overall performance and to plan strategic communication with the State Government on its outcomes. The quitline has limitations of its informal existence through a voluntary effort of RCF, no specific resource allocation, suboptimal data management, minimal awareness in the masses due to poor IEC (Information, Education and Communication; except its efforts made by RCF in last 1 year through the government-run State TV and City Radio) and staff shortage and its attrition due to lack of plan for career advancement. Despite these challenges in the year 2013, the quit line has registered a quit rate (for complete abstinence) of 19.93% amongst 1525 callers. The quit rate were 58.01% (304/ 524) among the responders at the 3rd follow-up at 18 months (in September 2014)2. In view of an increase in quit rate by 5- 9 times over the prevailing quit rate in the former ever daily users [both smokers and the users of smokeless tobacco (SLT)], efforts are being made by RCF in concurrence with PS to have this cost-effective model established formally with optimal resource allocation in collaboration with willing agencies (the State and Central Governments and the International Quitline Agencies) and its replication in 4 more states

    The debate on non-human future-oriented cognition has long revolved around the question whether such cognition at all occurs. Closer inspection reveals just how much cognition in general-down to its simplest forms-is geared toward predicting the future in a bid to maintain homeostasis and fend off entropy. Over the course of life's existence on Earth, evolution and natural selection have, through a series of evolutionary arms races, gotten increasingly good at achieving this. Prospection has reached its current pinnacle based partly on a system for episodic cognition that-as research increasingly is showing-is not limited principally to human beings. Nevertheless, and despite some notable recent defections, many researchers remain convinced of the merits of the Bischof-Köhler Hypothesis with its claim that no species other than human beings is able to anticipate future needs or otherwise live in anything other than the immediate present moment. What might, at first, appear to be empirical disputes turn out to reveal largely unquestioned theoretical divides. Without due care, one risks setting out conditions for 'true' future orientation that are irrelevant for describing human cognition. In sorting out the theoretical and terminological muddle framing contemporary debate, this article makes a plea for moving beyond past dogmas while putting animal prospection research into the context of evolution and contemporary cognitive science.

  12. An assessment of EIA system in India

    Panigrahi, Jitendra K.; Amirapu, Susruta

    2012-07-15

    Environmental impact assessment (EIA) was first introduced in India based on the Environmental Protection Act (EPA), 1986. But formally it came in to effect, when Ministry of Environment and Forest (MoEF) has passed a major legislative measure under EPA in January 1994 for Environmental Clearance (EC) known as EIA Notification, 1994. Subsequently, EIA processes have been strengthened by MoEF by a series of amendments. The current practice is adhering to EIA Notification, 2006 and its amendments. The pieces of evidence collected and analysis in the present assessment suggest that, despite a sound legislative, administrative and procedural set-up EIA has not yet evolved satisfactorily in India. An appraisal of the EIA system against systematic evaluation criteria, based on discussions with various stakeholders, EIA expert committee members, approval authorities, project proponents, NGOs and consulting professionals, reveals various drawbacks of the EIA system. These mainly include; inadequate capacity of EIA approval authorities, deficiencies in screening and scoping, poor quality EIA reports, inadequate public participation and weak monitoring. Overall, EIA is used presently as a project justification tool rather than as a project planning tool to contribute to achieving sustainable development. While shortcomings are challenging, Government of India is showing a high degree of commitment. The EIA system in the country is undergoing progressive refinements by steadily removing the constraints. The paper identifies opportunities for taking advantage of the current circumstances for strengthening the EIA process. - Highlights: Black-Right-Pointing-Pointer An assessment has been carried out on Environmental Clearance under EIA Notification, 2006, MoEF, Government of India.

  13. Transits of Venus and Colonial India

    Astronomical expeditions during the colonial period had a political and national significance also. Measuring the earth and mapping the sky were activities worthy of powerful and power- seeking nations. Such was the sanctity of global astronomical activity that many other agendas could be hidden under it. An early astronomy-related expedition turned out to be extremely beneficial, to botany. The expedition sent by the French Government in 1735 to South America under the leadership of Charles Marie de la Condamine (1701--1774) ostensibly for the measurement of an arc of the meridian at Quito in Ecuador surreptitiously collected data that enabled Linnaeus to describe the genus cinchona in 1742. When the pair of transits of Venus occurred in 1761 and 1769, France and England were engaged in a bitter rivalry for control of India. The observation of the transits became a part of the rivalry. A telescope presented by the British to a South Indian King as a decorative toy was borrowed back for actual use. Scientifically the transit observations were a wash out, but the exercise introduced Europe to details of living Indian tradition of eclipse calculations. More significantly, it led to the institutionalization of modern astronomy in India under the auspices of the English East India Company (1787). The transits of Venus of 1874 and 1882 were important not so much for the study of the events as for initiating systematic photography of the Sun. By this, Britain owned most of the world's sunshine, and was expected to help European solar physicists get data from its vast Empire on a regular basis. This and the then genuinely held belief that a study of the sun would help predict failure of monsoons led to the institutionalization of solar physics studies in India (1899). Of course, when the solar physicists learnt that solar activity did not quite determine rainfall in India, they forgot to inform the Government.

    2014-01-01

    Background Suicide is an important cause of death in India but estimated suicide rates based on data from India’s National Crime Records Bureau are unreliable. Aim Systematically review existing literature on suicide and the factors associated with suicide in India. Methods PubMed, PsycINFO, EMBASE, Global Health, Google Scholar and IndMED were searched using appropriate search terms. The abstracts of relevant papers were independently examined by both authors for possible inclusion. A standardized set of data items were abstracted from the full text of the selected papers. Results Thirty-six papers met inclusion criteria for the analysis. The heterogeneity of sampling procedures and methods of the studies made meta-analysis of the results infeasible. Verbal autopsy studies in several rural locations in India report high suicide rates, from 82 to 95 per 100,000 population – up to 8-fold higher than the official national suicide rates. Suicide rates are highest in persons 20 to 29 years of age. Female suicide rates are higher than male rates in persons under 30 years of age but the opposite is true in those 30 years of age or older. Hanging and ingestion of organophosphate pesticides are the most common methods of suicide. Among women, self-immolation is also a relatively common method of suicide. Low socioeconomic status, mental illness (especially alcohol misuse) and inter-personal difficulties are the factors that are most closely associated with suicide. Conclusion The quality of the information about suicide in India is quite limited, but it is clearly an important and growing public health problem. Compared to suicides in high-income countries, suicide in India is more prevalent in women (particularly young women), is much more likely to involve ingestion of pesticides, is more closely associated with poverty, and is less closely associated with mental illness.

    2015-01-01

    Diverse features of motor learning have been reported by numerous studies, but no single theoretical framework concurrently accounts for these features. Here, we propose a model for motor learning to explain these features in a unified way by extending a motor primitive framework. The model assumes that the recruitment pattern of motor primitives is determined by the predicted movement error of an upcoming movement (prospective error). To validate this idea, we perform a behavioural experiment to examine the model’s novel prediction: after experiencing an environment in which the movement error is more easily predictable, subsequent motor learning should become faster. The experimental results support our prediction, suggesting that the prospective error might be encoded in the motor primitives. Furthermore, we demonstrate that this model has a strong explanatory power to reproduce a wide variety of motor-learning-related phenomena that have been separately explained by different computational models.

  17. Climatic and evolutionary drivers of phase shifts in the plague epidemics of colonial India

    2016-01-01

    Immune heterogeneity in wild host populations indicates that disease-mediated selection is common in nature. However, the underlying dynamic feedbacks involving the ecology of disease transmission, evolutionary processes, and their interaction with environmental drivers have proven challenging to characterize. Plague presents an optimal system for interrogating such couplings: Yersinia pestis transmission exerts intense selective pressure driving the local persistence of disease resistance among its wildlife hosts in endemic areas. Investigations undertaken in colonial India after the introduction of plague in 1896 suggest that, only a decade after plague arrived, a heritable, plague-resistant phenotype had become prevalent among commensal rats of cities undergoing severe plague epidemics. To understand the possible evolutionary basis of these observations, we developed a mathematical model coupling environmentally forced plague dynamics with evolutionary selection of rats, capitalizing on extensive archival data from Indian Plague Commission investigations. Incorporating increased plague resistance among rats as a consequence of intense natural selection permits the model to reproduce observed changes in seasonal epidemic patterns in several cities and capture experimentally observed associations between climate and flea population dynamics in India. Our model results substantiate Victorian era claims of host evolution based on experimental observations of plague resistance and reveal the buffering effect of such evolution against environmental drivers of transmission. Our analysis shows that historical datasets can yield powerful insights into the transmission dynamics of reemerging disease agents with which we have limited contemporary experience to guide quantitative modeling and inference.

    A fourth-generation scanner has been modified to perform prospectively gated cardiac computed tomography (CT). A computer program monitors the electrocardiogram (ECG) and predicts when to initiate the next scan in a gated series in order to acquire all projection data for a desired phase of the heart cycle. The system has been tested with dogs and has produced cross-sectional images of all phases of the cardiac cycle. Eight to ten scans per series were sufficient to obtain reproducible images of each transverse section in the end-diastolic and end-systolic phases. The radiation dose to the skin was approximately 1.4 cGy per scan. The prospectively gated system is more than twice as efficient as a retrospectively gated system in obtaining complete angular projection data for a 10% heart cycle window. A temporal smoothing technique to suppress reconstruction artifacts due to sorting inconsistent projection data was developed and evaluated. Image noise was reduced by averaging together any overlapping projection data. Prospectively gated cardiac CT has also been used to demonstrate that the error in attenuation measured with a single nongated CT scan through the heart can be as large as 50-60 CT numbers outside the heart in the lung field.

    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.

    Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between these two biodiesel pathways compared to fossil diesel, by taking into account possible uncertainties. The geographical location of this study is India with a prospect of utilizing available wastelands in southern regions. The results indicate that the environmental performance of algal biodiesel is comparable to that of jatropha biodiesel. Both show significant GHG emission and fossil energy depletion reductions which are in the range of 36-40 and 10-25% respectively compared to fossil diesel in the studied geographic context.

    Enteroviruses have been reported in encephalitis cases. However, clinical and epidemiological characteristics of enteroviruses in encephalitis are not fully established. We prospectively investigated 204 children with encephalitis over a period of 2 years (2009 to 2010) for enterovirus. Enterovirus was detected in 45 specimens (22.1%); of these, 40 were typed by seminested reverse transcription-PCR (RT-PCR) and sequencing of the VP1 gene. Molecular typing of enterovirus revealed the predominance of echovirus 21 associated with an epidemic during the rainy seasons of 2010 and the circulation of echovirus 1, coxsackievirus B1, enterovirus 75, enterovirus 76, coxsackievirus B5, and echovirus 19. The nucleotide divergence among echovirus 21 strains was 0 to 2% at the nucleotide level. This study suggests that enterovirus is an important cause of encephalitis in children from India. To our knowledge, this is the first report of echovirus 21 in encephalitis cases worldwide.

    Global pharmaceutical companies face an increasingly harsh environment for their primary business of selling medicines. They have to contend with a spiraling decline in the productivity of their R&D programs that is guaranteed to severely diminish their growth prospects. Outsourcing of drug discovery activities to low-cost locations is a growing response to this crisis. However, the upsides to outsourcing are capped by the failure of global pharmaceutical companies to take advantage of the full range of possibilities that this model provides. Companies that radically rethink and transform the way they conduct R&D, such as seeking the benefits of low-cost locations in India and China will be the ones that thrive in this environment. In this article we present our views on how the outsourcing model in drug discovery should go beyond increasing the efficiency of existing drug discovery processes to a fundamental rethink and re-engineering of these processes.

    Rapid, but unplanned urban development and the consequent urban sprawl coupled with economic growth have aggravated auto dependency in India over the last two decades. This has resulted in congestion and pollution in cities. The central and state governments have taken many ameliorative measures to reduce vehicular emissions. However, evolution of scientific methods for emission inventory is crucial. Therefore, an attempt has been made to estimate the emissions (running and start) from on-road vehicles in Chennai using IVE model in this paper. GPS was used to collect driving patterns. The estimated emissions from motor vehicles in Chennai in 2005 were 431, 119, 46, 7, 4575, 29, and 0.41 tons/days respectively for CO, VOC, NO(x), PM, CO(2,) CH(4) and N(2)O. It is observed from the results that air quality in Chennai has degraded. The estimation revealed that two and three-wheelers emitted about 64% of the total CO emissions and heavy-duty vehicles accounted for more than 60% and 36% of the NO(x) and PM emissions respectively. About 19% of total emissions were that of start emissions. It is also estimated that on-road transport contributes about 6637 tons/day CO(2) equivalent in Chennai. This paper has further examined various mitigation options to reduce vehicular emissions. The study has concluded that advanced vehicular technology and augmentation of public transit would have significant impact on reducing vehicular emissions.

    The origin of the circular structure at Lonar, India, described variously as cauldron, pit, hollow, depression, and crater, has been a controversial subject since the early nineteenth century. A history of its origin and other aspects from 1823 to 1990 are overviewed. The structure in the Deccan Trap Basalt is nearly circular with a breach in the northeast, 1830 m in diameter, 150 m deep, with a saline lake in the crater floor. Over the years, the origin of the Lonar structure has risen from volcanism, subsidence, and cryptovolcanism to an authentic meteorite impact crater. Lonar is unique because it is probably the only terrestrial crater in basalt and is the closest analog with the Moon's craters. Some unresolved questions are suggested. The proposal is made that the young Lonar impact crater, which is less than 50,000 years old, should be considered as the best crater laboratory analogous to those of the Moon, be treated as a global monument, and preserved for scientists to comprehend more about the mysteries of nature and impact cratering, which is now emerging as a fundamental ubiquitous geological process in the evolution of the planets.

    Thunderstorm, resulting from vigorous convective activity, is one of the most spectacular weather phenomena in the atmosphere which is associated with thunder, squall lines and lightening. On 13 April 2010, a severe storm struck parts of Bangladesh and eastern India which lasted about 90 minutes, with the most intense portion spanning 30-40 minutes. The severe Thunderstorm on 13th April 2010 spawned a large tornado, which lasted about 20 minutes and was the first tornado recorded in Bihar history. In the year 2015, Bihar experienced a similar storm on 21 April during which multiple microbursts were observed. Various meteorological parameters have been analyzed to study the factors affecting the development of the thunderstorm. Satellite images from KALPANA and Meteosat has been analyzed to capture the temporal and spatial evolution of these storms. The satellite images show the development of a convective clouds system in the early afternoon hours which developed further into the severe storms by late evening. The analysis carried out further using K-index, lifted index, CAPE etc also shows the development of multiple cells of convection. Further analysis of these storms is presented in the paper.

  8. Understanding Changes in frequency of extreme rainfall over Central India

    2010-12-01

    There has been much recent interest in examining changes in rainfall extremes of the Indian Monsoon, especially over the so-called core monsoon (Central Indian) region. Few such studies however consider the attribution to climatic variables (indices) of the observed variability. Using gridded daily rainfall data from 1901-2004, an attempt is made here to understand the evolution of frequency of extreme rainfall over the core monsoon region, and its relationship to relevant climatic indices(Equatorial India Ocean SST, an index of the Indian Ocean Dipole, NINO indices (NINO 3.4 and 1.2)). Using an objective definition of "extreme rainfall"( such that the thresholds chosen vary with grids but not overtime), two types of analyses are carried out. First, using spectral analyses (Wavelet and Multi-Taper), the relationship between climate indices and frequency of extremes are investigated. Subsequently, in a very general framework of quantile regression for count data, the existence of time trends are analyzed jointly with significance of climate indices at distinct quantiles. This approach allows for separate effects of the climate indices at different quanitles, thereby allowing for a more detailed investigation of the various relationships of interest postulated in the literature.

    Pityriasis rosea is an acute self-limiting papulosquamous skin disorder of unknown etiology. Although pityriasis rosea is a common dermatologic disorder, information regarding the epidemiology of the disease in India is limited because of inadequate studies. The incidence and presentation of pityriasis rosea varies from one geographical region to another. The objective was to study the various clinical patterns of the disease and epidemiologic factors influencing its occurrence. A cross-sectional study on the clinicoepidemiologic pattern of pityriasis rosea was conducted. A detailed history of illness regarding onset, evolution, duration, symptoms, systemic features, recurrence, history of contact, and associated factors such as socioeconomic status, history of drug intake, and use of new clothing, along with epidemiologic data, was recorded in the performa. The age of the patients ranged from 3 to 47 (mean 20.32) years. Incidence of pityriasis rosea was highest among patients aged 11 to 20 years followed by those 21 to 30 years. There was a male preponderance. Seasonal variation was not evident. History of using new garments or old garments, unwashed for an extended period was elicited in 23% of cases. The average interval of onset of lesions and presentation to physician was 14.45 days. Pruritus was a common symptom (70%). Of 73 patients, 67 had herald patch. The clinical features of most of the cases were in accordance with the classical pattern of pityriasis rosea.

    This article presents a review of the history and evolution of robotic instrumentation and its applications in urology. A timeline for the evolution of robotic instrumentation is presented to better facilitate an understanding of our current-day applications. Some new directions including robotic microsurgical applications (robotic assisted denervation of the spermatic cord for chronic orchialgia and robotic assisted vasectomy reversal) are presented. There is a paucity of prospective comparative effectiveness studies for a number of robotic applications. However, right or wrong, human nature has always led to our infatuation with the concept of using tools to meet our needs. This chapter is a brief tribute to where we have come from and where we may be potentially heading in the field of robotic assisted urologic surgery. PMID:21116362

    We explore the impact of socio-demographic change on marriage patterns in India by examining the hypothetical consequences of applying three sets of marriage pairing propensities – contemporary patterns by age, by age and education, and changing propensities that allow for greater educational homogamy and reduced educational asymmetries – to future population projections. Future population prospects for India indicate three trends that will impact marriage patterns: i) female-deficit in sex ratios at birth; ii) declining birth cohort size; iii) female educational expansion. Existing literature posits declining marriage rates for men arising from skewed sex ratios at birth (SRB) in India’s population. In addition to skewed SRBs, India’s population will experience female educational expansion in the coming decades. Female educational expansion and its impact on marriage patterns must be jointly considered with demographic changes, given educational differentials and asymmetries in union formation that exist in India, as across much of the world. We systematize contemporary pairing propensities using data from the 2005–2006 Indian National Family Health Survey and the 2004 Socio-Economic Survey and apply these and the third set of changing propensities to IIASA/VID multi-state population projections by educational attainment using an iterative longitudinal projection procedure. If today’s age patterns of marriage are viewed against age-sex population composition until 2050, men experience declining marriage prevalence. However, when education is included, women, particularly those with higher education experience a more salient rise in non-marriage. Significant changes in pairing patterns towards greater levels of educational homogamy and gender symmetry can counteract a marked rise in non-marriage. PMID:25604846

    For some time, the reversibility of evolution was primarily discussed in terms of comparative patterns. Only recently has this problem been studied using experimental evolution over shorter evolutionary time frames. This has raised questions of definition, experimental procedure, and the hypotheses being tested. Experimental evolution has provided evidence for multiple population genetic mechanisms in reverse evolution, including pleiotropy and mutation accumulation. It has also pointed to genetic factors that might prevent reverse evolution, such as a lack of genetic variability, epistasis, and differential genotype-by-environment interactions. The main focus of this perspective is on laboratory studies and their relevance to the genetics of reverse evolution. We discuss reverse evolution experiments with Drosophila, bacterial, and viral populations. Field studies of the reverse evolution of melanism in the peppered moth are also reviewed.

    Prospective memory performance follows an inverted U-shaped function across the lifespan. Findings on the relative contribution of purely prospective memory and retrospective memory processes within prospective memory to this trajectory are scarce and inconclusive. We analyzed age-related differences in prospective memory performance across the lifespan in a cross-sectional design including six age groups (N = 99, 7-83 years) and investigated possible mechanisms by experimentally disentangling the relative contributions of retrospective memory and purely prospective memory processes. Results confirmed the inverted U-shaped function of prospective memory performance across the lifespan. A significant interaction between process type and age group was observed indicating differential relative contributions of retrospective memory and purely prospective memory processes on the development of prospective memory performance. Our results showed that mainly the pure prospective memory processes within prospective memory lead to lower prospective memory performance in young children and old adults. Moreover, the relative contributions of the retrospective memory and purely prospective memory processes are not uniform at both ends of the lifespan, i.e., in later adulthood the purely prospective memory processes seem to determine performance to an even greater extent than in childhood. Nevertheless, age effects were also observed in the retrospective component which thus contributed to the prospective memory performance differences between the age groups.
