In 1986, Poland's population was 37.5 million and the annual population growth rate was 0.8%. The infant mortality rate was 19.3/1000 and life expectancy stood at 71.6 years. Of the labor force of 17.5 million, 30% were engaged in agriculture, 44% were in industry and commerce, 8% were government employees, and 11% were employed in services. Poland is a communist state. The economy is based on the Soviet model of state ownership of most of the country's productive assets, although the private sector predominates in agriculture. The rights of private farmers are now protected through a 1983 amendment to the constitution. Poland's economy has performed poorly in comparison with other Eastern European economies. The economic growth rate is 5% and inflation averages 20%. Per capita income is US$2000. Industries were centralized following World War II, and this systemic rigidity is considered to have contributed to the economy's poor performance. Another important factor has been low reliance of foreign trade, meaning that Poland's industries have failed to develop competitiveness. The government has committed itself to a so-called second-stage of economic reform, but to date there have been few concrete accomplishments.

Functional outcomes in anterior cruciate ligament-deficient "potential copers" and "non-copers" may be related to their knee stabilization strategies. Therefore, the purpose of this study was to differentiate dynamic knee stabilization strategies of potential copers and non-copers through analysis of sagittal plane knee angle and tibia position during disturbed and undisturbed unilateral standing. Ten uninjured potential coper and non-coper subjects stood in unilateral stance on a platform that translated anteriorly, posteriorly and laterally. Knee angle and tibia position with reference to the femur were calculated before and after platform movement. During perturbation trials, potential copers maintained kinematics that were similar to uninjured subjects across conditions. Conversely, non-copers stood with greater knee flexion than uninjured subjects and a tibia position that was more posterior than the other groups. Both non-copers and potential copers demonstrated small changes in tibia position following platform movement, but direction of movement was not similar. The similarities between the knee kinematics of potential copers and uninjured subjects suggest that potential copers compensated well from their injury by utilizing analogous dynamic knee stabilization strategies. In comparison to the other groups, by keeping the knee in greater flexion and the tibia in a more posterior position, non-copers appear to constrain the tibia in response to a challenging task, which is consistent with a "stiffening strategy". Based on the poor functional outcomes of non-copers, a stiffening strategy does not lead to dynamic knee stability, and the strategy may increase compressive forces which could contribute to or exacerbate articular cartilage degeneration.

Defining and refining international donor support for combating the AIDS pandemic.

Attaran, A; Sachs, J

2001-01-06

The international aid effort against AIDS is greatly incommensurate with the severity of the epidemic. Drawing on the data that international aid donors self-reported to the Organization for Economic Cooperation and Development (OECD), we find that, between 1996 and 1998, finance from all rich countries to sub-Saharan Africa for projects designated as AIDS control averaged US $69 million annually, and, assuming a safe margin for under-reporting and misreporting, we estimate that total donor spending on HIV/AIDS control was perhaps twice that at most. Since the late 1980s, aid levels have dropped relative to the prevalence of HIV infection, and stood recently at about $3 per HIV-infected person. Lack of finance is now the primary constraint on progress against AIDS, notwithstanding the widespread belief that a lack of interest from the goveements of poor countries is limiting. We argue that to produce a meaningful response to the pandemic, international assistance must be based on grants, not loans, for the poorest countries; be increased within the next 3 years to a minimum of $7.5 billion or more; be directed toward funding projects which are proposed and desired by the affected countries themselves, and which are judged as having epidemiological merit against the pandemic by a panel of independent scientific experts; and fund concurrent needs, including prevention, drug treatment (such as highly active antiretroviral therapy), and blocking mother-to-child HIV transmission. An effort of this scope and scale will both radically alter the prospects for intervention against AIDS in poor countries, and together with comparable efforts to control other infectious diseases, is easily afforded by the OECD donor economies, whose aggregate national income recently surpassed $21 trillion annually.

Long-term mental health sequelae of the 1986 Chernobyl disaster have been documented for exposed populations who remained in the former Soviet Union (FSU) (Havenaar et al., 1997), and in a cohort migrated to Israel (Cwikel et al., 1997). This paper reports on Chernobyl disaster sequelae in émigrés (n = 321) to the United States. Demographic characteristics, migration factors, and self-reported physical health were considered. Both geographical proximity to the 1986 disaster, and perception of radiation risk stood as long-term indicators of current psychological distress. Proximity was related to poor self-perceived physical health, as well as current symptoms of depression (p<.05), anxiety (p<.01), and Chernobyl-related trauma distress (p<.001) on standardized measures. Environmental contamination as a reason for migration was also associated with greater mental health symptomatology.

A cross-sectional study carried out in a referral center in the outpatient care of people with hypertension and diabetes, with a sample of 285 individuals. The form used in the study was designed from operational definitions constructed for each DC of the diagnosis. Four nurses with training to carry out diagnostic inferences did the clinical assessment for the presence of SL. The prevalence of SL was 55.8%. Regarding measures of accuracy, the main DC for SL was chooses a daily routine lacking physical exercise, with sensitivity of 100% and specificity of 84.13%. Two DC stood out in the logistic regression, namely: reports preference for activities low in physical activity and poor performance in instrumental activities of daily living (IADL). The results allowed identifying the best clinical indicators for SL in hypertensive adults.

Air bubble location following embryo transfer (ET) is the presumable placement spot of embryos. The purpose of this study was to document endometrial air bubble position and migration following embryo transfer. Multicenter prospective case study. Eighty-eight embryo transfers were performed under abdominal ultrasound guidance in two countries by two authors. A single or double air bubble was loaded with the embryos using a soft, coaxial, end opened catheters. The embryos were slowly injected 10-20 mm from the fundus. Air bubble position was recorded immediately, 30 minutes later and when the patient stood up. Bubble marker location analysis revealed a random distribution without visible gravity effect when the patients stood up. The bubble markers demonstrated splitting, moving in all directions and dispersion. Air bubbles move and split frequently post ET with the patient in the horizontal position, suggestive of active uterine contractions. Bubble migration analysis supports a rather random movement of the bubbles and possibly the embryos. Standing up changed somewhat bubble configuration and distribution in the uterine cavity. Gravity related bubble motion was uncommon, suggesting that horizontal rest post ET may not be necessary. This report challenges the common belief that a very accurate ultrasound guided embryo placement is mandatory. The very random bubble movement observed in this two-center study suggests that a large "window" of embryo placement maybe present.

Population characteristics in the Lao People's Democratic Republic.

In 1990, demographers in Laos estimated population size at 4.2 million and population density at 18 persons/sq. km. In 1985, 50% of the people lived in provinces along the Mekong River most within 30 km of the river. 85% of the people dwelled in rural areas. Vientiane was the largest city. Even though there may be as many as 68 ethnic groups, in 1986, someone classified the Lao people into the Mon-Khmer speaking Lao Theung (22% of population), the Tibeto-Burman speaking Lao Soung (10%), and the T'ai speaking Lao Loum (68%). In 1985, the sex ratio stood at 96.1 males/100 females which was especially low among the 15-24 year old age group. This low ratio may be due to military activity, underreporting, and/or large scale out-migration. Many people have gone to Thailand and most were the former Lao elite and the educated middle class. 44% of the population was 15 years and 50% between 15-59 years. The 1988-1990 crude birth rate was 45 and the crude death rate 16. Total fertility rate stood at 6.8 (1987-1988). Despite the high rate, the government instituted a pronatalist population policy because of a relatively small population size and low density. In 1990, the government found infant mortality to be 116. Even though figures were unavailable, it believed maternal mortality was also high. Mortality differentials occurred between urban and rural areas. The government began expansion of health services with limited medical facilities and supplies and poor infrastructure. Further action was confined to urban areas. A maternal and child health care institute began as a means to reduce mortality and it promoted birth spacing. In 1986, the government estimated the labor force to be at 1.6 million with 90% in agriculture and forestry. Enrollment figures remained low in 1985, yet primary education was a primary priority. In the late 1980s, the government projected that the population would increase 32% in the 1990s.

In an emergency, a prompt response can save the lives of victims. This statement generates an imperative issue in emergency medical services (EMS). Designing a system that brings simplicity in locating emergency scenes is a step towards improving response time. This paper therefore implemented and evaluated the performance of an SMS-based emergency geolocation notification system with emphasis on its SMS delivery time and the system's geolocation and dispatch time. Using the RAS metrics recommended by IEEE for evaluation, the designed system was found to be efficient and effective as its reliability stood within 62.7% to 70.0% while its availability stood at 99% with a downtime of 3.65 days/year.

Impact of stimulus format and reward value on quantity discrimination in capuchin and squirrel monkeys.

PubMed

Gazes, Regina Paxton; Billas, Alison R; Schmitt, Vanessa

2018-03-01

Quantity discrimination abilities are seen in a diverse range of species with similarities in performance patterns, suggesting common underlying cognitive mechanisms. However, methodological factors that impact performance make it difficult to draw broad phylogenetic comparisons of numerical cognition across studies. For example, some Old World monkeys selected a higher quantity stimulus more frequently when choosing between inedible (pebbles) than edible (food) stimuli. In Experiment 1 we presented brown capuchin (Cebus [Sapajus] paella) and squirrel monkeys (Saimiri sciureus) with the same two-choice quantity discrimination task in three different stimulus conditions: edible, inedible, and edible replaced (in which choice stimuli were food items that stood in for the same quantity of food items that were given as a reward). Unlike Old World monkeys, capuchins selected the higher quantity stimulus more in the edible condition and squirrel monkeys showed generally poor performance across all stimulus types. Performance patterns suggested that differences in subjective reward value might motivate differences in choice behavior between and within species. In Experiment 2 we manipulated the subjective reinforcement value of the reward by varying reward type and delay to reinforcement and found that delay to reinforcement had no impact on choice behavior, while increasing the value of the reward significantly improved performance by both species. The results of this study indicate that species presented with identical tasks may respond differently to methodological factors such as stimulus and reward types, resulting in significant differences in choice behavior that may lead to spurious suggestions of species differences in cognitive abilities.

Chronic exposure to musical auditory stimulation has been reported to improve cardiac autonomic regulation. However, it is not clear if music acutely influences it in response to autonomic tests. We evaluated the acute effects of music on heart rate variability (HRV) responses to the postural change maneuver (PCM) in women. We evaluated 12 healthy women between 18 and 28 years old and HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) and frequency (LF, HF and LF/HF ratio) domains. In the control protocol, the women remained at seated rest for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. In the music protocol, the women remained at seated rest for 10 minutes, were exposed to music for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. HRV was recorded at the following time: rest, music (music protocol) 0-5, 5-10 and 10-15 min during standing. In the control protocol the SDNN, RMSSD and pNN50 indexes were reduced at 10-15 minutes after the volunteers stood up, while the LF (nu) index was increased at the same moment compared to seated rest. In the protocol with music, the indexes were not different from control but the RMSSD, pNN50 and LF (nu) were different from the music period. Musical auditory stimulation attenuates the cardiac autonomic responses to the PCM.

West Nile virus (WNV) causes an acute neurological infection attended by massive neuronal cell death. However, the mechanism(s) behind the virus-induced cell death is poorly understood. Using a library containing 77,406 sgRNAs targeting 20,121 genes, we performed a genome-wide screen followed by a second screen with a sub-library. Among the genes identified, seven genes, EMC2, EMC3, SEL1L, DERL2, UBE2G2, UBE2J1, and HRD1, stood out as having the strongest phenotype, whose knockout conferred strong protection against WNV-induced cell death with two different WNV strains and in three cell lines. Interestingly, knockout of these genes did not block WNV replication. Thus, these appear to be essential genes that link WNV replication to downstream cell death pathway(s). In addition, the fact that all of these genes belong to the ER-associated protein degradation (ERAD) pathway suggests that this might be the primary driver of WNV-induced cell death.

1969-01-01

The prevalence of varicose veins was studied in 504 women cotton workers in England and 467 in Egypt, by a standardized questionary and a specially developed method of examination. The English mill population showed a much higher prevalence of varicose veins than the Egyptian, probably owing to environmental rather than ethnic reasons. Among the European women the prevalence of varicose veins was significantly related to age, parity, body weight, type of corsetry, and occupation—that is, whether or not they stood at their work. After standardizing for the other variables there was a statistically significant excess of varicose veins in women wearing corsets and roll-ons compared with those wearing less-constrictive garments. After a similar standardization a significant excess was found in women who stood at their work compared with those whose jobs entailed walking or sitting. Imagesp593-a PMID:5798468

Water transparency is an important ecological indicator for shallow lakes. The largest shallow lake, Poyang Lake, as well as the most typical river-connected lake in China was selected as the research area. In view of the complicated water-sediment conditions induced by its frequent water exchange with external rivers, the dominant factors driving water transparency were determined against the field investigated data from 2003 to 2013 and a specific driving function was established. A numerical model coupling suspended sediment, Chl-a and chemical oxygen demand was developed and validated, and the spatial water transparency distributions under three typical current structures in Poyang Lake, Gravity-style, Jacking-style and Backflow-style, were quantitatively estimated. The following results stood out: water transparency in the lake varied distinctly with the current status; Backflow-style current was basically characterized by the lowest water transparency, while that under Jacking-style was the highest due to the lower sediment carrying capacity. In some outlying regions in the lake, where the water current is hardly influenced by the mainstream, the water transparency was always kept at a stable level.

2004-11-01

The corrosion behaviours of austenitic steel AISI 316L and martensitic steel T91 were investigated in flowing lead-bismuth eutectic (LBE) at 400 °C. The tests were performed in the LECOR and CHEOPE III loops, which stood for the low oxygen concentration and high oxygen concentration in LBE, respectively. The results obtained shows that steels were affected by dissolution at the condition of low oxygen concentration ( C[O 2] = 10 -8-10 -10 wt%) and were oxidized at the condition of high oxygen concentration ( C[O 2] = 10 -5-10 -6 wt%). The oxide layers detected are able to protect the steels from dissolution in LBE. Under the test condition adopted, the austenitic steel behaved more resistant to corrosion induced by LBE than the martensitic steel.

Development of Mullite Substrates and Containers

Sibold, J. D.

1979-01-01

The mullite-molten silicon interaction was evaluated through fabrication of a series of bodies made with variations in density, alumina-silica ratio, and glass-crystalline ratio. The materials were tested in a sessile drop technique. None of the variations stood up to extended exposure to molten silicon sufficiently to be recommended as a container material. However, directional solidification experiments suggest that, under proper conditions, contamination of the silicon by mullite containers can be minimized. To improve an already good thermal expansion match between mullite and silicon, compositional variations were studied. Altering of the alumina-silica ratio was determined to give a continuously varying thermal expansion. A standard mullite composition was selected and substrates 40 x 4 x .040 inches were fabricated. Slotted substrates of various configurations and various compositions were also fabricated.

Work ability may be considered as an important aspect of well-being and health status. One of the most important factors in association with work ability is health-related quality of life (HRQoL). The aim of this study has been to determine the association between work ability, individual characteristics and HRQoL of female workers. The design of this study has been cross-sectional. The work ability index (WAI) and Short-Form General Health Survey (SF-12) questionnaires were used to collect data. Three hundred and twenty female workers were selected from food supplier factories in Karaj. One-way analysis of variance, Pearson's correlation analysis, independent sample t-test and multiple linear regression methods were used to analyze data. Mean (M) and standard deviation (SD) of the WAI stood at 35.02 and 5.57, respectively. The categories of the WAI for women being as follows: 8.8% poor, 62% moderate, 25.4% good and 3.7% excellent. Mean±SD for the physical component summary (PCS) and mental component summary (MCS) of quality of life was 58.84±11.12 and 57.45±9.94, respectively. There was a positive significant association between the PCS and MCS with the WAI (p = 0.0001). Workers with higher education had a better work ability (p = 0.002) and shift-work workers had a worse work ability (p = 0.03). Work ability of majority of women was moderate. Considering mean age of studied women (27.6 years old), this work ability is not satisfactory. Physical and mental components of the HRQoL were the important factors associated with work ability.

This study analyses the relationship between the antecedents and consequences of health literacy (HL) at the ecological level among the nations involved in the European Health Literacy Survey (HLS-EU). The antecedents and consequences were investigated by means of proxy indicators. The HL was measured using the 47-item HLS-EU questionnaire (HLS-EUQ47) and the Newest Vital Sign (NVS). The two measures stood in significant correlation to the outcomes of the sub-discipline of the Euro Health Consumer Index (r = 0.790 for HLS-EUQ47; r = 0.789 for NVS). The HLS-EUQ47 also stood in correlation to the percentage of population with post-secondary education (r = 0.810), the reading performance for 15-year-old students (r = 0.905), the presence of a national screening program for breast (r = 0.732) or cervical cancer (r = 0.873). The NVS stood in correlation with the unemployment rate (r = −0.778), the Gross Domestic Product (r = 0.719), the Gini coefficient (r = −0.743), the rank of the Euro Patient Empowerment Index (r = −0.826), the expenditure on social protection (r = 0.814), the Consumer Empowerment Index (r = 0.898), the percentage of adults using the internet for seeking health information (r = 0.759), the prevalence of overweight individuals (r = −0.843), the health expenditure (r = 0.766), as well as the percentage of individuals using the internet for interacting with public authorities (r = 0.755). This study provides some preliminary considerations regarding alternative means by which to study HL and proposes new methods for experimentation. The methods and the results could offer a means by which the relationship between society and overall healthcare protection could be strengthened.

Schizophrenia in the News: The Role of News Frames in Shaping Online Reader Dialogue about Mental Illness.

PubMed

Gwarjanski, Anna Rae; Parrott, Scott

2018-08-01

A quantitative content analysis examined the portrayal of schizophrenia in eight of the most read online news publications in the United States. The analysis documented the prevalence of stigma frames, which communicate stereotypes concerning schizophrenia, and stigma-challenge frames, which contradict stereotypes, in 558 articles related to schizophrenia. The study also examined the relationship between media framing and reader commentary, including the likelihood of readers posting stigmatizing comments, stigma-challenging comments, and comments in which they disclosed personal experience with mental illness. Stigma frames were prevalent in the sample, suggesting the news media continue associating schizophrenia with violent and criminal behavior. Stigma frames stood greater chance of being accompanied by stigmatizing comments from readers when compared to stigma-challenging frames. Conversely, stigma-challenging frames stood greater chance of being accompanied by stigma-challenging comments from readers. Readers were more likely to disclose personal experience with mental illness when they encountered a stigma-challenging frame. Recommendations are made for journalists and health communicators.

Correlations between PAH bioavailability, degrading bacteria, and soil characteristics during PAH biodegradation in five diffusely contaminated dissimilar soils.

2014-01-01

The natural biodegradation of seven polycyclic aromatic hydrocarbons (PAHs) by native microorganisms was studied in five soils from Normandy (France) from diffusely polluted areas, which can also pose a problem in terms of surfaces and amounts of contaminated soils. Bioavailability tests using cyclodextrin-based extractions were performed. The natural degradation of low molecular weight (LMW) PAHs was not strongly correlated to their bioavailability due to their sorption to geosorbents. Conversely, the very low degradation of high molecular weight (HMW) PAHs was partly correlated to their poor availability, due to their sorption on complexes of organic matter and kaolinites or smectites. A principal component analysis allowed us to distinguish between the respective degradation behaviors of LMW and HMW PAHs. LMW PAHs were degraded in less than 2-3 months and were strongly influenced by the relative percentage of phenanthrene-degrading bacteria over total bacteria in soils. HMW PAHs were not significantly degraded, not only because they were less bioavailable but also because of a lack of degrading microorganisms. Benzo[a]pyrene stood apart since it was partly degraded in acidic soils, probably because of a catabolic cooperation between bacteria and fungi.

Two Isomeric C16 Oxo-Fatty Acids from the Diatom Chaetoceros karianus Show Dual Agonist Activity towards Human Peroxisome Proliferator-Activated Receptors (PPARs) α/γ

The peroxisome proliferator-activated receptors (PPARs) function as ligand-activated transcription factors that convert signals in the form of lipids to physiological responses through the activation of metabolic target genes. Due to their key roles in lipid and carbohydrate metabolism, the PPARs are important drug targets. However, for several of the PPAR drugs currently in use, adverse side effects have been reported. In an effort to identify compounds from marine organisms that may serve as molecular scaffolds for the development of novel and safer PPAR-targeting drugs, we performed a bioassay-guided screening of organic extracts made from organisms supplied by the Norwegian Biobank of Arctic Marine Organisms (Marbank). Among several interesting hits, we identified two poorly described isomeric oxo-fatty acids from the microalgae Chaetoceros karianus for which we provide the first evidence that they might display dual specificity towards human PPARα and PPARγ. Principal component analysis showed that C. karianus stood out from other Chaetoceros species, both with respect to the metabolic profile and the PPAR activity. The isolation of these compounds holds the potential of uncovering a PPAR pharmacophore with tunable activity and specificity. PMID:28587091

Cure fraction model with random effects for regional variation in cancer survival.

Seppä, Karri; Hakulinen, Timo; Kim, Hyon-Jung; Läärä, Esa

2010-11-30

Assessing regional differences in the survival of cancer patients is important but difficult when separate regions are small or sparsely populated. In this paper, we apply a mixture cure fraction model with random effects to cause-specific survival data of female breast cancer patients collected by the population-based Finnish Cancer Registry. Two sets of random effects were used to capture the regional variation in the cure fraction and in the survival of the non-cured patients, respectively. This hierarchical model was implemented in a Bayesian framework using a Metropolis-within-Gibbs algorithm. To avoid poor mixing of the Markov chain, when the variance of either set of random effects was close to zero, posterior simulations were based on a parameter-expanded model with tailor-made proposal distributions in Metropolis steps. The random effects allowed the fitting of the cure fraction model to the sparse regional data and the estimation of the regional variation in 10-year cause-specific breast cancer survival with a parsimonious number of parameters. Before 1986, the capital of Finland clearly stood out from the rest, but since then all the 21 hospital districts have achieved approximately the same level of survival.

In 1985, the population of the Democratic People's Republic of Korea (North Korea) stood at 20 million, with an annual growth rate of 2.3%. The infant mortality rate was 30/1000 live births and life expectancy was 66 years. The gross national product (GNP) was US$23 billion in 1984, with a per capita GNP of $1175. Both North Korea's labor force and natural resources have been concentrated in recent years on an effort to achieve rapid economic development. During the early 1970s, a large-scale modernization program involving the importation of Western technology, primarily in the heavy industiral sectors of the economy, was attempted and resulted in a massive foreign debt. North Korea has a strongly centralized government under the control of the communist Korean Workers' Party. Literacy in the country is at the 99% level. Medical treatment is free. There is 1 physician/600 population and 1 hospital bed/350 inhabitants.

2016-09-23

Various guidelines for the protection of human beings against possible adverse effects resulting from exposure to electromagnetic fields (EMFs) have been published with a view towards continual improvement; therefore, decreasing exposure is an important research area. The aim of this study was to investigate the possibility of decreasing electric field exposure with arc flash rated personal protective equipment (PPE), which in this case was a set of coveralls, and to compare the measurement results to calculations using the helmet-mask measuring system. We collected the data under a 400-kV power line. The test person stood on isolated aluminum paper, and the current between the ground and the aluminum paper was measured. When the test subject wore the arc flash PPE, the current to the ground was only 9.5% of the current measured when wearing normal clothes, which represents a clear decrease in exposure.

US Air Force perspective on validated NDE - Past, present, and future

NASA Astrophysics Data System (ADS)

Lindgren, Eric A.

2016-02-01

The concept of inspection has accompanied aviation since the work of the Wright Brothers. Inspection for both initial quality/materials acceptance and readiness for flight have been coupled with US Air Force (USAF) since its inception as the US Army Signal Corps. Initial nondestructive evaluation work expanded beyond visual inspection to include radiography and magnetic particle in the 1920's and 1930's as air frames transitioned to metal and engines used higher strength steels. Within the USAF Research and Development community, a Nondestructive Test Section was stood up in 1952 and the Nondestructive Evaluation Branch (NDE) was established in 1974. In 2012 the name was changed to the Materials State Awareness Branch. This name change reflects the evolution from a primary focus on inspections for damage and defects in materials to the characterization of the underlying materials structure that governs properties of the materials of interest for Air Force applications.

Bipedal distribution of human vestibular-evoked postural responses during asymmetrical standing

PubMed Central

Marsden, J F; Castellote, J; Day, B L

2002-01-01

Galvanic vestibular stimulation (GVS) evokes responses in muscles of both legs when bilateral stimuli are applied during normal stance. We have used this technique to assess whether asymmetrical standing alters the distribution of responses in the two legs. Subjects stood either asymmetrically with 75 % of their body weight on one leg or symmetrically with each leg taking 50 % of their body weight. The net response in each leg was taken from changes in ground reaction force measured from separate force plates under each foot. The net force profile consisted of a small initial force change that peaked at ∼200 ms followed by an oppositely directed larger component that peaked at ∼450 ms. We analysed the second force component since it was responsible for the kinematic response of lateral body sway and tilt towards the anode. In the horizontal plane, both legs produced lateral force responses that were in the same direction but larger in the leg ipsilateral to the cathodal ear. There were also vertical force responses that were of equal size in both legs but acted in opposite directions. When subjects stood asymmetrically the directions of the force responses remained the same but their magnitudes changed. The lateral force response became 2-3 times larger for the more loaded leg and the vertical forces increased 1.5 times on average for both legs. Control experiments showed that these changes could not be explained by either the consistent (< 5 deg) head tilt towards the side of the loaded leg or the changes in background muscle activity associated with the asymmetrical posture. We conclude that the redistribution of force responses in the two legs arises from a load-sensing mechanism. We suggest there is a central interaction between load-related afferent input from the periphery and descending motor signals from balance centres. PMID:12096073

Treatment of cows with parturient paresis using intravenous calcium and oral sodium phosphate.

PubMed

Braun, U; Grob, D; Hässig, M

2016-09-01

The goal of this study was to investigate whether intravenous infusion of 1000 ml 40% calcium borogluconate combined with the oral adminstration of 500 g sodium phosphate leads to a better cure rate and longer-lasting normocalcaemia and normophosphataemia than standard intravenous treatment with 500 ml calcium borogluconate in cows with parturient paresis. Forty recumbent cows with hypocalcaemia and hypophosphataemia were alternately allocated to group A or B. Cows of both groups were treated intravenously with 500 ml 40% calcium borogluconate, and cows of group B additionally received another 500 ml calcium borogluconate via slow intravenous infusion and 500 g sodium phosphate administered via an orogastric tube. Thirty-two cows stood within 8 hours after the start of treatment and 8 did not; of the 32 cows that stood, 18 belonged to group A and 14 to group B (90% of group A vs. 70% of group B; P = 0.23). Seven cows relapsed; of these and the 8 that did not respond to initial treatment, 10 stood after two standard intravenous treatments. Downer cow syndrome occurred in 5 cows, 3 of which recovered after aggressive therapy. The overall cure rate did not differ significantly between groups A and B. Twelve (60%) cows of group A and 14 (70%) cows of group B were cured after a single treatment and of the remaining 14, 11 were cured after two or more treatments. Two downer cows were euthanized and one other died of heart failure during treatment. Serum calcium concentrations during the first eight hours after the start of treatment were significantly higher in group B than in group A, and oral sodium phosphate caused a significant and lasting increase in inorganic phosphate. More cows of group B than group A were cured after a single treatment (P > 0.05). These findings, although not statistically significant, are promising and should be verified using a larger number of cows.

Male circumcision to prevent syphilis in 1855 and HIV in 1986 is supported by the accumulated scientific evidence to 2015: Response to Darby.

PubMed

Morris, Brian J; Wamai, Richard G; Krieger, John N; Banerjee, Joya; Klausner, Jeffrey D

2017-10-01

An article by Darby disparaging male circumcision (MC) for syphilis prevention in Victorian times (1837-1901) and voluntary medical MC programs for HIV prevention in recent times ignores contemporary scientific evidence. It is one-sided and cites outlier studies as well as claims by MC opponents that support the author's thesis, but ignores high quality randomised controlled trials and meta-analyses. While we agree with Darby that risky behaviours contribute to syphilis and HIV epidemics, there is now compelling evidence that MC helps reduce both syphilis and HIV infections. Although some motivations for MC in Victorian times were misguided, others, such as protection against syphilis, penile cancer, phimosis, balanitis and poor hygiene have stood the test of time. In the absence of a cure or effective prophylactic vaccine for HIV, MC should help lower heterosexually acquired HIV, especially when coupled with other interventions such as condoms and behaviour. This should save lives, as well as reducing costs and suffering. In contrast to Darby, our evaluation of the evidence leads us to conclude that MC would likely have helped reduce syphilis in Victorian times and, in the current era, will help lower both syphilis and HIV, so improving global public health.

EPR: Evidence and fallacy.

PubMed

Nichols, Joseph W; Bae, You Han

2014-09-28

The enhanced permeability and retention (EPR) of nanoparticles in tumors has long stood as one of the fundamental principles of cancer drug delivery, holding the promise of safe, simple and effective therapy. By allowing particles preferential access to tumors by virtue of size and longevity in circulation, EPR provided a neat rationale for the trend toward nano-sized drug carriers. Following the discovery of the phenomenon by Maeda in the mid-1980s, this rationale appeared to be well justified by the flood of evidence from preclinical studies and by the clinical success of Doxil. Clinical outcomes from nano-sized drug delivery systems, however, have indicated that EPR is not as reliable as previously thought. Drug carriers generally fail to provide superior efficacy to free drug systems when tested in clinical trials. A closer look reveals that EPR-dependent drug delivery is complicated by high tumor interstitial fluid pressure (IFP), irregular vascular distribution, and poor blood flow inside tumors. Furthermore, the animal tumor models used to study EPR differ from clinical tumors in several key aspects that seem to make EPR more pronounced than in human patients. On the basis of this evidence, we believe that EPR should only be invoked on a case-by-case basis, when clinical evidence suggests the tumor type is susceptible. Copyright © 2014 Elsevier B.V.

The effect of horizontal acceleration on human visual acuity and stereopsis is demonstrated in this study. Twenty participants (mean age 22.6 years) were enrolled in the experiment. Acceleration from two different directions was performed at the Taiwan High-Speed Rail Laboratory. Gx and Gy (< and >0.1 g) were produced on an accelerating platform where the subjects stood. The visual acuity and stereopsis of the right eye were measured before and during the acceleration. Acceleration <0.1 g in the X- or Y-axis did not affect dynamic vision and stereopsis. Vision decreased (mean from 0.02 logMAR to 0.25 logMAR) and stereopsis declined significantly (mean from 40 s to 60.2 s of arc) when Gx > 0.1 g. Visual acuity worsened (mean from 0.02 logMAR to 0.19 logMAR) and poor stereopsis was noted (mean from 40 s to 50.2 s of arc) when Gy > 0.1 g. The effect of acceleration from the X-axis on the visual system was higher than that from the Y-axis. During acceleration, most subjects complained of ocular strain when reading. To our knowledge, this study is the first to report the exact levels of visual function loss during Gx and Gy. PMID:25607601

Bullying and employee turnover among healthcare workers: a three-wave prospective study.

Hogh, Annie; Hoel, Helge; Carneiro, Isabella G

2011-09-01

To investigate the risk of turnover among targets of bullying at work. Exposure to bullying seems to leave targets with intentions to leave their workplaces. However, it is uncertain to what extent they actually leave. Data were collected by questionnaires in a three-wave study among Danish healthcare workers at the time of graduation (T₁ ), 1 (T₂ ) and 2 years (T₃ ) later. We followed 2154 respondents who participated in all three waves. The first year after graduation, 9.2% reported being bullied at work, 1.8% frequently. Follow-up analyses showed a strong relationship between exposure to bullying at T₂ and turnover at T₃ [odds ratio (OR) for frequently bullied = 3.1]. The inclusion of push factors such as low social support and low sense of community, intention to leave and ill health did not change the relation between bullying and turnover significantly. Three reasons for quitting stood out among reasons given by the bullied respondents: poor leadership, being exposed to negative behaviour and health problems. Bullying may be costly to an organization in terms of staff turnover and subsequent recruitment and training of replacements. IMPACT FOR NURSING MANAGEMENT: Managers should regularly monitor the psychosocial work environment. To prevent bullying local policies and procedures should be developed, implemented and evaluated. 2011 Blackwell Publishing Ltd.

Role of arm motion in feet-in-place balance recovery.

PubMed

Cheng, Kuangyou B; Wang, Kuan-Mao; Kuo, Shih-Yu

2015-09-18

Although considerable arm movements have been observed at loss of balance, research on standing balance focused primarily on the ankle and hip strategies. This study aimed to investigate the effect of arm motion on feet-in-place balance recovery. Participants stood on a single force plate and leaned forward with a straight body posture. They were then released from three forward-lean angles and regained balance without moving their forefeet under arm-swing (AS) and arm-constrained (AC) conditions. Higher success rates and shorter recovery times were found with arm motion under moderate balance perturbations. Recovery time was significantly correlated with peak linear momentum of the arms. Circumduction arm motion caused initial shoulder extension (backward arm movement) to generate reaction forces to pull the body forward, but later forward linear momentum of the arms helped move the whole body backward to avoid forward falling. However, greater lean angles increased difficulty in balance recovery, making the influences of the arms less significant. Since arm motions were observed in all participants with significantly enhanced performance under moderate balance perturbation, it was concluded that moving the arms should also be considered (together with the ankles and hips) as an effective strategy for balance recovery.

HOW DOES ADDING AND REMOVING LIQUID FROM SOCKET BLADDERS AFFECT RESIDUAL LIMB FLUID VOLUME?

PubMed Central

Sanders, JE; Cagle, JC; Harrison, DS; Myers, TR; Allyn, KJ

2015-01-01

Adding and removing liquid from socket bladders is a means for people with limb loss to accommodate residual limb volume change. Nineteen people with trans-tibial amputation using their regular prosthetic socket fitted with fluid bladders on the inside socket surface underwent cycles of bladder liquid addition and removal. In each cycle, subjects sat, stood, and walked for 90s with bladder liquid added and then sat, stood, and walking for 90s again with the bladder liquid removed. The amount of bladder liquid added was increased in each cycle. Bioimpedance analysis was implemented to measure residual limb fluid volume. Results showed that the preferred bladder liquid volume was 16.8 mL (s.d.8.4), corresponding to 1.7% (s.d.0.8%) of the average socket volume between the bioimpedance voltage-sensing electrodes. Limb fluid volume driven out of the residual limb when bladder liquid was added was typically not recovered upon subsequent bladder liquid removal. Fifteen of nineteen subjects experienced a gradual limb fluid volume loss over the test session. Care should be taken when implementing adjustable socket technologies in people with limb amputation. Reducing socket volume may accentuate limb fluid volume loss. PMID:24203546

Healthy workers who stand for prolonged periods show enhanced production of reactive oxygen species (ROS) in their systemic circulation. Oxidative stress is thought to be a risk factor for chronic venous insufficiency and other systemic diseases. To evaluate the effectiveness of compression stockings in the prevention of oxidative stress at work. ROS and venous pressure of the lower limbs were measured in 55 theatre nurses who stood in the operating theatre for >6 h, 23 industrial ironers who stood for up to 5 h during their shift and 65 outpatient department nurses and 35 laundry workers who acted as controls. Subjects and controls were examined on two consecutive days before and after work and with and without compression stockings. Without compression stockings, lower limb venous pressure increased significantly after work in all subjects and controls (P < 0.001), while only operating theatre nurses showed significantly higher mean levels of ROS (P < 0.001). There was no significant difference in venous pressures and ROS levels after work in subjects or controls when wearing compression stockings. Our data suggest a preventive role of compression stockings against oxidative stress in healthy workers with a standing occupation.

How gender and task difficulty affect a sport-protective response in young adults

PubMed Central

Lipps, David B.; Eckner, James T.; Richardson, James K.; Ashton-Miller, James A.

2013-01-01

We tested the hypotheses that gender and task difficulty affect the reaction, movement, and total response times associated with performing a head protective response. Twenty-four healthy young adults (13 females) performed a protective response of raising their hands from waist level to block a foam ball fired at their head from an air cannon. Participants initially stood 8.25 m away from the cannon (‘low difficulty’), and were moved successively closer in 60 cm increments until they failed to block at least 5 of 8 balls (‘high difficulty’). Limb motion was quantified using optoelectronic markers on the participants’ left wrist. Males had significantly faster total response times (p = 0.042), a trend towards faster movement times (p = 0.054), and faster peak wrist velocity (p < .001) and acceleration (p = 0.032) than females. Reaction time, movement time, and total response time were significantly faster under high difficulty conditions for both genders (p < .001). This study suggests that baseball and softball pitchers and fielders should have sufficient time to protect their head from a batted ball under optimal conditions if they are adequately prepared for the task.

Quantitative studies of radiation damage in high-purity germanium gamma-ray detectors due to high-energy charged particles have been carried out; two 1.0 cm thick planar detectors were irradiated by 6 GeV/c protons. Under proton bombardment, degradation in the energy resolution was found to begin below 7 x 10 to the 7th protons/sq cm and increased proportionately in both detectors until the experiment was terminated at a total flux of 5.7 x 10 to the 8th protons/sq cm, equivalent to about a six year exposure to cosmic-ray protons in space. At the end of the irradiation, the FWHM resolution measured at 1332 keV stood at 8.5 and 13.6 keV, with both detectors of only marginal utility as a spectrometer due to the severe tailing caused by charge trapping. Annealing these detectors after proton damage was found to be much easier than after neutron damage.

2000-10-01

Since the invention of quantum mechanics, even the simplest example of collisional breakup in a system of charged particles, e - + H --> H+ + e- + e-, has stood as one of the last unsolved fundamental problems in atomic physics. A complete solution requires calculating the energies and directions for a final state in which three charged particles are moving apart. Advances in the formal description of three-body breakup have yet to lead to a viable computational method. Traditional approaches, based on two-body formalisms, have been unable to produce differential cross sections for the three-body final state. Now, by using a mathematical transformation of the Schrödinger equation that makes the final state tractable, a complete solution has finally been achieved. Under this transformation, the scattering wave function can be calculated without imposing explicit scattering boundary conditions. This approach has produced the first triple differential cross sections that agree on an absolute scale with experiment as well as the first ab initio calculations of the single differential cross section [29].

2016-01-01

Various guidelines for the protection of human beings against possible adverse effects resulting from exposure to electromagnetic fields (EMFs) have been published with a view towards continual improvement; therefore, decreasing exposure is an important research area. The aim of this study was to investigate the possibility of decreasing electric field exposure with arc flash rated personal protective equipment (PPE), which in this case was a set of coveralls, and to compare the measurement results to calculations using the helmet-mask measuring system. We collected the data under a 400-kV power line. The test person stood on isolated aluminum paper, and the current between the ground and the aluminum paper was measured. When the test subject wore the arc flash PPE, the current to the ground was only 9.5% of the current measured when wearing normal clothes, which represents a clear decrease in exposure.

The role of the microcirculation in the pathophysiology and symptoms of peripheral arterial obliterative disease (PAOD) has been progressively emphasized during the past decades. Under resting conditions, already, the tissue oxygen partial pressure in the m. tibialis anterior (pO2im) is reduced to about 50% compared to healthy subjects. In the framework of this study the pO2im of patients with PAOD stage II according to Fontaine (n=16) in the m. tibialis anterior was measured under resting conditions and during walking on a treadmill in comparison to healthy subjects (n=10). Under resting conditions the pO2im only marginally differed between PAOD patients and healthy subjects. But during exercise the pO2im dropped significantly more severely in PAOD patients and a return to baseline values could only be reached when the treadmill was stopped and the patients stood still. The pO2im minima correlated clearly with the clinical symptom of calf pain. The data revealed that the pO2im values were lower in PAOD patients and dropped significantly faster during walking compared to the pO2im values in healthy subjects. The pO2im decrease correlated with the calf pain occurring when the pO2im values approached or fell below 10 mmHg.

During 1981-1986, 86 maternal deaths transpired at the obstetrics department of the Jawaharlal Institute of Postgraduate Medical Education and Research in Pondicherry, India. The maternal mortality rate stood at 5.8/1000 births. 31.4% were primigravidae. The percentage of maternal deaths characterized as gravidae 2-4, 5, and multigravidae was 42.9%, 9.3%, and 16.4%, respectively. The leading causes of death were sepsis (41.9%), especially septic abortion (30.2%); eclampsia-severe preeclampsia (10.5%); ruptured uterus (9.3%); and hemorrhage and prolonged labor (8.1% each). Direct obstetric causes of death accounted for 81.4% of all maternal deaths. Indirect obstetric causes of death were hepatitis (5.8%), heart disease (4.7%), and severe anemia (2.3%). Most of the women who died were illiterate (97.6%), poor (98.8%), and had received no prenatal care (94.2%). 47.7% traveled more than 60 km to the hospital. Quacks or untrained traditional birth attendants had excessively interfered with about 33% before they reached the hospital, especially the septic induced abortion, obstructed labor, and ruptured uterus cases. Among the 48 women who delivered before dying, there were 24 live births (5 of whom died during the early neonatal period) and 24 still births. These findings indicate a need for a cooperative effort to improve and expand maternal and child health care in the community.

2011-01-01

We investigated age-related changes and sex differences in adaptability of anticipatory postural control in children. Subjects comprised 449 children (4-12 years old) and 109 young adults (18-29 years old). Subjects stood with eyes closed on a force-platform fixed to a floor oscillator. We conducted five trials of 1-minute oscillation (0.5 Hz frequency, 2.5 cm amplitude) in the anteroposterior direction. Postural steadiness was quantified as the mean speed of the center of pressure in the anteroposterior direction (CoPy). In young adults, CoPy speed decreased rapidly until the third trial for both sexes. Adaptability was evaluated by changes in steadiness. The adaptability of children was categorized as "good," "moderate," and "poor," compared with a standard variation of the mean CoPy speed regression line between the first and fifth trials in young adults. Results were as follows: (1) anticipatory postural control adaptability starts to develop from age 6 in boys and 5 in girls, and greatly improves at age 7-8 in boys and 6 in girls; (2) the adaptability of children at age 11-12 (74% of boys and 63% of girls were categorized as "good") has not yet reached the same level as for young adults; (3) the adaptability at age 11-12 for girls is temporarily disturbed due to early puberty.

The skeleton responds to mechanical stimulation. We wished to ascertain the magnitude and speed of the growing skeleton’s response to a standardised form of mechanical stimulation, vibration. 36 prepubertal boys stood for 10 minutes in total on one of two vibrating platforms (high (>2 g) or low (<1 g) magnitude vibration) on either 1, 3 or 5 successive days (n=12 for each duration); 15 control subjects stood on an inactive platform. Blood samples were taken at intervals before and after vibration to measure bone formation (P1NP, osteocalcin) and resorption (CTx) markers as well as osteoprotegerin and sclerostin. There were no significant differences between platform and control groups in bone turnover markers immediately after vibration on days 1, 3 and 5. Combining platform groups, at day 8 P1NP increased by 25.1% (CI 12.3 to 38.0; paired t-test p=0.005) and bone resorption increased by 10.9% (CI 3.6 to 18.2; paired t-test p=0.009) compared to baseline. Osteocalcin, osteoprotogerin and sclerostin did not change significantly. The growing skeleton can respond quickly to vibration of either high or low magnitude.

In 1986, France had a population of 55,493,000, with an annual growth rate of 0.4%. The infant mortality rate stood at 8.2/1000. Of the work force of 23.8 million, 8.3% were engaged in agriculture, 45.2% were in the industry and commerce sector, and 46.5% were engaged in services. The unemployment rate stood at 10.7%. The country's gross domestic product (GDP) was US$724 billion in 1986, with an average annual growth rate of 2.0%, and per capita income averaged $13,046. France has substantial agricultural resources, a diversified modern industrial system, and a highly skilled labor force. Following the return of a socialist majority in government in 1981, several large manufacturing firms were nationalized along with much of the commercial banking sector. Initial socialist policies were stimulative, relying partly on income redistribution and partly on increased government spending. However, the resultant increase in import demand was not offset by an increased demand French exports. In 1983, an economic stabilization plan of reductions in the budget deficit, involving spending cuts, increased taxes, and tighter monetary and credit policies, was successfully implemented. Although current economic policies should promote stronger growth over the medium to long term, trade competitiveness remains weak and high unemployment is a major social problem.

The existence of these strategies was examined in 13 below-knee prosthesis users and 15 controls during dual-task standing under increasing postural and cognitive challenge by evaluating path length, 95% sway area, and anterior-posterior and medial-lateral amplitudes of the center of pressure. The subjects stood on two force platforms under usual (hard surface/eyes open) and difficult (soft surface/eyes closed) conditions, first alone and while performing a cognitive task without and then with instruction on cognitive prioritization. During standing alone, sway was not significantly different between groups. After adding the cognitive task without prioritization instruction, prosthesis users increased sway more under the dual-task than single-task standing (p ≤ 0.028) during both usual and difficult conditions, favoring the posture second strategy. Controls, however, reduced dual-task sway under a greater postural challenge (p ≤ 0.017), suggesting the posture first strategy. With prioritization of the cognitive task, sway was unchanged or reduced in prosthesis users, suggesting departure from the posture second strategy, whereas controls maintained the posture first strategy. Individual analysis of dual tasking revealed that greater postural demand in controls and greater cognitive challenge in prosthesis users led to both reduced sway and improved cognitive performance, suggesting cognitive-motor facilitation. Thus, activation of additional resources through increased alertness, rather than posture prioritization, may explain dual-task performance in both prosthesis users and controls under increasing postural and cognitive challenge.

Estimated Under-Five Deaths Associated with Poor-Quality Antimalarials in Sub-Saharan Africa

Many antimalarials sold in sub-Saharan Africa are poor-quality (falsified, substandard, or degraded), and the burden of disease caused by this problem is inadequately quantified. In this article, we estimate the number of under-five deaths caused by ineffective treatment of malaria associated with consumption of poor-quality antimalarials in 39 sub-Saharan countries. Using Latin hypercube sampling our estimates were calculated as the product of the number of private sector antimalarials consumed by malaria-positive children in 2013; the proportion of private sector antimalarials consumed that were of poor-quality; and the case fatality rate (CFR) of under-five malaria-positive children who did not receive appropriate treatment. An estimated 122,350 (interquartile range [IQR]: 91,577–154,736) under-five malaria deaths were associated with consumption of poor-quality antimalarials, representing 3.75% (IQR: 2.81–4.75%) of all under-five deaths in our sample of 39 countries. There is considerable uncertainty surrounding our results because of gaps in data on case fatality rates and prevalence of poor-quality antimalarials. Our analysis highlights the need for further investigation into the distribution of poor-quality antimalarials and the need for stronger surveillance and regulatory efforts to prevent the sale of poor-quality antimalarials.

Cadmium is a highly toxic heavy metal, which has a destroying impact on organs. Exposure to cadmium causes severe health problems to human beings due to its ubiquitous environmental presence and features of the pathologies associated with pro-longed exposure. Cadmium is a well-established carcinogen, although the underlying mechanisms have not been fully under-stood yet. Recently, there has been considerable interest in the impact of this environmental pollutant on the epigenome. Be-cause of the role of epigenetic alterations in regulating gene expression, there is a potential for the integration of cadmium-induced epigenetic alterations as critical elements in the cancer risk assessment process. Here, after a brief review of the ma-jor diseases related to cadmium exposure, we focus our interest on the carcinogenic potential of this heavy metal. Among the several proposed pathogenetic mechanisms, particular attention is given to epigenetic alterations, including changes in DNA methylation, histone modifications and non-coding RNA expression. We review evidence for a link between cadmium-induced epigenetic changes and cell transformation, with special emphasis on melanoma. DNA methylation, with reduced expression of key genes that regulate cell proliferation and apoptosis, has emerged as a possible cadmium-induced epigenetic mechanism in melanoma. A wider comprehension of mechanisms related to this common environmental contaminant would allow a better cancer risk evaluation. PMID:25646071

We have fabricated well-aligned ZnO nanorod arrays (ZNRAs) on indium tin oxide-coated glass substrates by a facile chemical bath deposition method. We used field-emission scanning electron microscope, x-ray diffraction and UV-Vis absorption spectroscopy to study the morphology, crystalline structure and optical absorption of the fabricated ZNRAs, respectively. The results showed that ZnO nanorods stood almost perpendicularly on the substrate, were about 30-50 nm in diameter and 800-900 nm in length, and were wurtzite-structured (hexagonal) ZnO. In addition, well-aligned ZNRAs exhibited a weak absorption in the visible region and had an optical band gap value of 3.28 eV. Furthermore, a hybrid ZNRAs/polymer photovoltaic device was made, under 1 sun AM 1.5 illumination (light intensity, ˜100 mW/cm2), and the device showed an open circuit voltage ( V oc) of 0.32 V, a short circuit current density ( J sc) of 7.67 mA/cm2, and a fill factor ( FF) of 0.37, yielding an overall power conversion efficiency of 0.91%. Also, the exciton dissociation and transportation processes of charge carriers in the device under illumination were explained according to its current density-voltage ( J- V) curve and the energy level diagram.

The effect of neck torsion on postural stability in subjects with persistent whiplash.

Dysfunction of cervical receptors in neck disorders has been shown to lead to disturbances in postural stability. The neck torsion manoeuvre used in the smooth pursuit neck torsion (SPNT) test is thought to be a specific measure of neck afferent dysfunction on eye movement in those with neck pain. This study aimed to determine whether neck torsion could change balance responses in those with persistent whiplash-associated disorders (WADs). Twenty subjects with persistent WAD and 20 healthy controls aged between 18 and 50 years stood on a computerised force plate with eyes closed in comfortable stance under 5 conditions: neutral head, head turned to left and right and neck torsion to left and right. Root mean square (rms) amplitude of sway was measured in the anterior-posterior (AP) and medial-lateral (ML) directions. The whiplash group had significantly greater rms amplitude in the AP direction following neck torsion compared to the control group (p < 0.03). The results show that the neck torsion manoeuvre may lead to greater postural deficits in individuals with persistent WAD and provides further evidence of neck torsion to identify abnormal cervical afferent input, as an underlying cause of balance disturbances in WAD. Further research is warranted. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

The medical life of Henry Norman Bethune

Deslauriers, Jean; Goulet, Denis

2015-01-01

BACKGROUND: Henry Norman Bethune is one of the most exciting and incredible surgeons that Canada has ever produced. Indeed, he is often characterized as one of the world’s best-known surgeons. He was an innovator and his scientific contributions have stood the test of time. In Canada, he will forever be remembered as a social activist committed to the welfare of the poor and to the reform of the health care system. In the People’s Republic of China, he is idolized and remains the only foreigner to ever become a national hero. OBJECTIVE: To detail the numerous and significant achievements of Henry Norman Bethune in the field of thoracic surgery and as a social activist and describe his heroic war-time actions on the battlefields of both Spain and China. METHOD: Information was gathered through the reading of the numerous publications written about the life and work of Bethune, interviews with knowledgeable people from Canadian and Chinese universities, analysis of Bethune’s own publications, and extensive experience of one of the authors in China. RESULTS: In the social sense, Henry Norman Bethune had a difficult personality, but he was deeply caring about the plight of his patients, especially the poor. As a thoracic surgeon, he could be ingenious, thoughtful and effective but he could also be abrasive, restless and temperamental. His scientific contributions were sound and, at the time, gained worldwide attention. As an activist, he led a crusade to reform the Canadian health care system, demanding free health care for all. His outstanding work during the Spanish Civil War, where he organized the first ever mobile blood transfusion unit, and during the Sino-Japanese war, where he was totally committed to the welfare of both soldiers and civilian population, were deliberate acts of resistance against Fascist onslaught and enthusiasm for the Communist cause. CONCLUSIONS: Henry Norman Bethune was unconventional and a revolutionary, but he was brilliant. He will forever be remembered as an innovative thoracic surgeon and outstanding humanitarian.

Laparoscopic Heller myotomy has emerged as an excellent primary treatment for patients with dysphagia secondary to achalasia. A laparoscopic rather than thoracoscopic approach has stood the test of time. An antireflux procedure combined with the myotomy is crucial to the maintenance of the antireflux barrier. Thoracoscopic long myotomy offers effective relief for spastic disorders of the esophagus. Endoscopic stapled diverticulotomy is a safe and effective procedure for Zenker's diverticulum and has potential advantages over the open approach.

Spectator attendance to professional basketball in Turkey is significantly less than desired. Keeping in mind how important spectators are for team sports, understanding factors that affect game attendance will offer essential clues in terms of increasing spectator attendance. The main purpose of this study was to determine the relationships between basketball spectators' motives and points of attachment. With consideration to this purpose, the present study has tested the validity and reliability of the Motivation Scale for Sport Consumption and the Points of Attachment Index for Turkish basketball spectators. 197 basketball spectators participated in the study. Confirmatory factor analysis results demonstrated that the original models of the measurement tools employed for the study showed an acceptable degree of fit with the data. The internal consistency coefficients of the scales were found to be between 0.59 and 0.80 for the Motivation Scale for Sport Consumption and between 0.53 and 0.88 for the Points of Attachment Index. The canonical correlation analysis only returned a single significant function. The motives aesthetics and escape stood out in terms of the significant function, while the sport type (basketball in this study) stood out in the sense of attachment. Relationships identified between basketball spectators' motives and points of attachment could help sports managers and marketing experts to develop strategies focusing on increasing spectator attendance to their teams' games.

Intrinsic ankle stiffness during standing increases with ankle torque and passive stretch of the Achilles tendon

PubMed Central

Gill, Jaspret

2018-01-01

Individuals may stand with a range of ankle angles. Furthermore, shoes or floor surfaces may elevate or depress their heels. Here we ask how these situations impact ankle stiffness and balance. We performed two studies (each with 10 participants) in which the triceps surae, Achilles tendon and aponeurosis were stretched either passively, by rotating the support surface, or actively by leaning forward. Participants stood freely on footplates which could rotate around the ankle joint axis. Brief, small stiffness-measuring perturbations (<0.7 deg; 140 ms) were applied at intervals of 4–5 s. In study 1, participants stood at selected angles of forward lean. In study 2, normal standing was compared with passive dorsiflexion induced by 15 deg toes-up tilt of the support surface. Smaller perturbations produced higher stiffness estimates, but for all perturbation sizes stiffness increased with active torque or passive stretch. Sway was minimally affected by stretch or lean, suggesting that this did not underlie the alterations in stiffness. In quiet stance, maximum ankle stiffness is limited by the tendon. As tendon strain increases, it becomes stiffer, causing an increase in overall ankle stiffness, which would explain the effects of leaning. However, stiffness also increased considerably with passive stretch, despite a modest torque increase. We discuss possible explanations for this increase. PMID:29558469

Dicentric chromosomes: unique models to study centromere function and inactivation

PubMed Central

Stimpson, Kaitlin M.; Matheny, Justyne E.

2013-01-01

Dicentric chromosomes are products of genome rearrangement that place two centromeres on the same chromosome. Depending on the organism, dicentric stability varies after formation. In humans, dicentrics occur naturally in a substantial portion of the population and usually segregate successfully in mitosis and meiosis. Their stability has been attributed to inactivation of one of the two centromeres, creating a functionally monocentric chromosome that can segregate normally during cell division. The molecular basis for centromere inactivation is not well under-stood, although studies in model organisms and in humans suggest that genomic and epigenetic mechanisms can be involved. Furthermore, constitutional dicentric chromosomes ascertained in patients presumably represent the most stable chromosomes, so the spectrum of dicentric fates, if it exists, is not entirely clear. Studies of engineered or induced dicentrics in budding yeast and plants have provided significant insight into the fate of dicentric chromosomes. And, more recently, studies have shown that dicentrics in humans can also undergo multiple fates after formation. Here, we discuss current experimental evidence from various organisms that has deepened our understanding of dicentric behavior and the intriguingly complex process of centromere inactivation.

2014-01-01

The aim of the present study is the exploration of the compensation mechanisms in healthy adults elicited by superimposing a horizontal perturbation, through a rotation of the support base, during a whole body active rotation around the participant's own vertical body axis. Eight healthy participants stood on a rotating platform while executing 90° whole body rotations under three conditions: no concurrent platform rotation (NP), support surface rotation of ± 45° in the same (45-S) and opposite (45-O) directions. Participants' kinematics and CoP displacements were analyzed with an optoelectronic system and a force platform. In both 45-S and 45-O conditions, there was a tendency for the head to be affected by the external perturbation and to be the last and least perturbed segment while the pelvis was the most perturbed. The observed reduced head perturbation in 45-S and 45-O trials is consistent with a goal-oriented strategy mediated by vision and vestibular information, whereas the tuning of lumbar rotation is consistent with control mechanisms mediated by somato-sensory information.

The volatile profiles of six plum cultivars ('Laetitia', 'Primetime', 'Sapphire', 'Showtime', 'Songold' and 'Souvenir') produced under two management systems (conventional and organic) and harvested in two consecutive years were obtained by HS-SPME-GC-MS. Twenty-five metabolites were determined, five of which (pentanal, (E)-2-heptenal, 1-octanol, eucalyptol and 2-pentylfuran) are reported for the first time in Prunus salicina Lindl. Hexanal stood out as a major volatile compound affected by the management system. In addition, partial least square discriminant analysis (PLS-DA) achieved an effective classification of genotypes based on their volatile profiles. A high classification accuracy model was obtained with a sensitivity of 97.9% and a specificity of 99.6%. Furthermore, the application of a dual criterion, based on a method of variable selection, VIP (variable importance in projection) and the results of a univariate analysis (ANOVA), allowed the identification of potential volatile markers in 'Primetime', 'Showtime' and 'Souvenir' genotypes (cultivars not characterised to date).

Can vibratory feedback be used to improve postural stability in persons with transtibial limb loss?

PubMed

Rusaw, David; Hagberg, Kerstin; Nolan, Lee; Ramstrand, Nerrolyn

2012-01-01

The use of vibration as a feedback modality to convey motion of the body has been shown to improve measures of postural stability in some groups of patients. Because individuals using transtibial prostheses lack sensation distal to the amputation, vibratory feedback could possibly be used to improve their postural stability. The current investigation provided transtibial prosthesis users (n = 24, mean age 48 yr) with vibratory feedback proportional to the signal received from force transducers located under the prosthetic foot. Postural stability was evaluated by measuring center of pressure (CoP) movement, limits of stability, and rhythmic weight shift while participants stood on a force platform capable of rotations in the pitch plane (toes up/toes down). The results showed that the vibratory feedback increased the mediolateral displacement amplitude of CoP in standing balance and reduced the response time to rapid voluntary movements of the center of gravity. The results suggest that the use of vibratory feedback in an experimental setting leads to improvements in fast open-loop mechanisms of postural control in transtibial prosthesis users.

Diptera of Medico-Legal Importance Associated With Pig Carrion in a Tropical Dry Forest.

2016-06-20

The diversity of necrophagous Diptera is largely unknown in seasonally dry tropical forests, despite their medical, veterinary, and forensic relevance. We performed a study in the dry Caatinga forest exclusive to Brazil in order to assess the diversity and temporal pattern of Diptera species using pig carcasses as substrates. Adults were collected daily until complete skeletonization. We collected 17,142 adults from 18 families, 10 of which comprise species with known necrophagous habits. The most abundant families were Calliphoridae (47.3% of specimens), Sarcophagidae (20.8%), and Muscidae (15.5%), whereas Sarcophagidae stood out in terms of richness with 21 species. The native Cochliomyia macellaria (F.) (Diptera: Calliphoridae) and the invasive Chrysomya albiceps (Wiedmann) (Calliphoridae) were the dominant species. A total of 18 species reached the carcass during the first 48 h postdeath. The bloated and active decay stages had the highest richness and abundance of dipterans. From a forensic standpoint, C. macellaria and C. albiceps are likely to aid in establishing postmortem interval due to their early arrival and high abundance on the carcass. Despite harsh environmental conditions, the Caatinga harbors a rich assemblage of dipterans that play a key role in carrion decomposition. Their medico-veterinary importance is strengthened by the poor local sanitary conditions. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

People with a lower socioeconomic position have a higher the prevalence of most self-rated health problems. In this article we ask whether this may be attributed to self-rated health not reflecting actual health, understood as mortality, in different socioeconomic groups. For the study we used data from the Nord-Trøndelag Health Study 1984-86 (HUNT1), in which the county's entire adult population aged 20 years and above were invited to participate. The association between self-rated health and mortality in different occupational classes and income groups was analysed. The analysis corrected for age, chronic disease, functional impairment and lifestyle factors. The association between self-rated health and mortality was of the same order of magnitude for the occupational classes and income groups, but persons without work/income and with poor self-rated health stood out. Compared with persons in the highest socioeconomic class, unemployed men had a hazard ratio for death that was three times higher in the follow-up period. For women with no income, the ratio was twice as high. INTERPRETATION Self-rated health and mortality largely conform to the different socioeconomic strata. This supports the perception that socioeconomic differences in health are a reality and represent a significant challenge nationally. Our results also increase the credibility of findings from other studies that use self-reported health in surveys to measure differences and identify the mechanisms that create them.

The maintenance of quality and integrity in clinical and basic science research depends upon peer review. This process has stood the test of time and has evolved to meet increasing work loads, and ways of detecting fraud in the scientific community. However, in the 21st century, the emphasis on evidence-based medicine and good science has placed pressure on the ways in which the peer review system is used by most journals. This paper reviews the peer review system and the problems it faces in the digital age, and proposes possible solutions.

McLaughlin formulated a novel explanation for the Martian albedo markings and their variations. This explanation, the volcanic-aeolian hypothesis, is one of the very few prespacecraft views of planet-wide phenomena on Mars which have stood the test of time. The distribution of albedo markings is considered along with secular changes on Mars and seasonal changes in region Syrtis Major. Mariner 9 has demonstrated that aeolian transport is the dominant factor in determining the distribution of albedo markings on Mars.

Socioeconomic inequalities in injury morbidity are an important yet understudied issue in Southern Europe. This study analysed the injuries treated in primary care in the Community of Madrid, Spain, by socioeconomic status (SES), sex and age. This was a cross-sectional study of injuries registered in the primary care electronic medical records of the Madrid Health Service in 2012. Incidence stratified by sex, SES and type of injury were calculated. Poisson regression was performed. A statistically significant upward trend in global injury incidence was observed with decreasing SES in all age groups. By type of injury, the largest differences were observed in injuries by foreign body in men aged 15-44 and in poisonings in girls under 15 years of age. Burns risk also stood out in the group of girls under 15 years of age with the lowest SES. In the group above 74 years of age, wounds, bruises and sprains had the lowest SES differences in both sexes, and the risk of fractures was lower in the most socioeconomically advantaged group. People with lower SES were at a greater risk of injury. The relationship between SES and injury varies by type of injury and age. © The Author 2016.

1989-12-01

Pseudomonas S-42 was capable of decolorizing azo dyes such as Diamira Brilliant Orange RR(DBO-RR), Direct Brown M (DBM), Eriochrome Brown R(EBR) and so on. The cell suspension, cell-free extract and purified enzyme of Pseud. S-42 could decolorize azo dyes under similar conditions: the optimum pH and temperature laid 7.0 and 37 degrees C respectively. The efficiencies of decolorizing of DBO-RR, DBM, EBR by intact cells stood more than 90%. When the cell concentration was 15 mg(wet)/ml and the reaction time was 5 hours, the decolorizing activity for above three azo dyes by intact cells were 1.75, 2.4, 0.95 micrograms dye/mg cell, respectively. Cell-free extract and purified enzyme could well express the decolorizing activity only under the anaerobic condition and added NADH. Purified enzyme belongs to azoreductase, its molecular weight is about 34,000-2000 daltons, and its Vmax and Km for DBO-RR are 13 mumol.mg protein-1.min-1 and 54 mumol/L. The results of the detection of the biodegrading products of DBO-RR by spectrophotometric and NaNO2 reactional methods showed that the biodegradation of azo dyes was initiated by the reduction cleavage of azo bonds. It was hypothesized that biodegrading metabolism pathway of DBO-RR by Pseudomonas S-42.

Bacterial biofilms are structured multicellular communities involved in a broad range of infections. Knowing how free-swimming bacteria adapt their motility mechanisms near surfaces is crucial for understanding the transition between planktonic and biofilm phenotypes. By translating microscopy movies into searchable databases of bacterial behavior, we identified fundamental type IV pili-driven mechanisms for Pseudomonas aeruginosa surface motility involved in distinct foraging strategies. Bacteria stood upright and "walked" with trajectories optimized for two-dimensional surface exploration. Vertical orientation facilitated surface detachment and could influence biofilm morphology.

Perceptual-Attentional and Motor-Intentional Bias in Near and Far Space

PubMed Central

Garza, John P.; Eslinger, Paul J.; Barrett, Anna M.

2008-01-01

Spatial bias demonstrated in tasks such as line-bisection may stem from perceptual-attentional (PA) “where” and motor-intentional (MI) “aiming” influences. We tested normal participants’ line bisection performance in the presence of an asymmetric visual distracter with a video apparatus designed to dissociate PA from MI bias. An experimenter stood as a distractor to the left or right of a video monitor positioned in either near or far space, where participants viewed lines and a laser point they directed under 1) natural and 2) mirror-reversed conditions. Each trial started with the pointer positioned at either the top left or top right corner of the screen, and alternated thereafter. Data analysis indicated that participants made primarily PA leftward errors in near space, but not in far space. Furthermore, PA, but not MI, bias increased bilaterally in the direction of distraction. In contrast, MI, but not PA, bias was shifted bilaterally in the direction of startside. Results support the conclusion that a primarily PA left sided bias in near space is consistent with right hemisphere spatial attentional dominance. A bottom-up visual distractor specifically affected PA “where” spatial bias while top-down motor cuing influenced MI “aiming” bias. PMID:18381226

OBJECTIVE: to analyze the accuracy of the defining characteristics of the Impaired gas exchange nursing diagnosis in children with acute respiratory infection. METHOD: open prospective cohort study conducted with 136 children monitored for a consecutive period of at least six days and not more than ten days. An instrument based on the defining characteristics of the Impaired gas exchange diagnosis and on literature addressing pulmonary assessment was used to collect data. The accuracy means of all the defining characteristics under study were computed. RESULTS: the Impaired gas exchange diagnosis was present in 42.6% of the children in the first assessment. Hypoxemia was the characteristic that presented the best measures of accuracy. Abnormal breathing presented high sensitivity, while restlessness, cyanosis, and abnormal skin color showed high specificity. All the characteristics presented negative predictive values of 70% and cyanosis stood out by its high positive predictive value. CONCLUSION: hypoxemia was the defining characteristic that presented the best predictive ability to determine Impaired gas exchange. Studies of this nature enable nurses to minimize variability in clinical situations presented by the patient and to identify more precisely the nursing diagnosis that represents the patient's true clinical condition.

Aruin, Alexander S; Kanekar, Neeta; Lee, Yun-Ju

2015-03-30

Deficit in balance control is a common and often an initial disabling symptom of multiple sclerosis (MS). The aim of the study was to investigate the organization of anticipatory and compensatory postural adjustments in individuals with MS dealing with external perturbations. Ten individuals with MS and ten age-and-gender matched healthy controls were exposed to external perturbations applied at the shoulder level. The perturbations were either predictable or unpredictable as subjects stood with eyes open or closed. Electrical activity of six leg and trunk muscles as well as displacements of the center of pressure (COP) were recorded and quantified within the time intervals typical of anticipatory (APAs) and compensatory (CPAs) postural adjustments. Individuals with MS demonstrated delayed anticipatory onsets of muscle activity and smaller anticipatory COP displacements as compared to healthy control subjects. The deficiency of the APAs was associated with increased displacements of the COP during the balance restoration phase. The results demonstrate the underlying impairment in anticipatory postural control of individuals with MS. The study outcome provides a background for development of rehabilitation strategies focused on balance restoration in people with MS. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

This article highlights population statistics from Peru, the 3rd largest country in Latin America. The population in 1985 has been estimated at 19.7 million. In 1982, the birth rate was 35/1000 and the mortality rate was 10/1000. Infant mortality stood at 99/1000 live births and life expectancy at birth was 59 years. 41% of Peru's population is under 15 years of age, and only 4% is 65 years of age or older. The country's total fertility rate is 5.2 births/woman. Only 0.4% of the population is foreign born. Peru is highly urbanized, and 65% of the country's total population growth in 1981 occurred in its cities. 1 in 3 Peruvians resides in the capital city of Lima. The 2 largest racial groups are mestizos and whites (53%) and Indians (46%). 21% of the population is illiterate. 40.7% of the labor force is employed in agriculture; however, only 15% of the national income is derived from agriculture. The GNP per capita was US$1040 in 1983. The country's economy is in serious trouble at present, with an annual inflation rate of 250% and a foreign debt of US$13.5 billion.

Seastacks buried beneath newly reported Lower Miocene sandstone, northern Santa Barbara County, California

Three large, isolated exposures of a light-gray, coarse-grained, thick-bedded sandstone unit occur in the northern San Rafael Mountains of Santa Barbara County, California. These rocks are moderately fossiliferous and contain Vertipecten bowersi, Amussiopecten vanvlecki, Aequipecten andersoni, Otrea howelli, shark teeth, whale bones, and regular echinoid spines. The fossils indicate that the sandstone unit, although previously reported as upper(.) Miocene, correlates best with the lower Miocene Vaqueros Formation. This unit was deposited in angular unconformity on a Cretaceous, greenish-gray turbidite sequence of interbedded sandstone and shale, and onlaps the unconformity erosion surface from west to east, the unit being thicker inmore » the west and older at its base. The underlying Cretaceous sandstone beds are well indurated, and during the eastward transgression of the early Miocene sea, they resisted wave erosion and stood as seastacks offshore of the advancing coastline, thus creating a very irregular topographic surface upon which the Vaqueros Formation was deposited. Some seastacks were as much as 4 m tall, as indicated by inliers of Cretaceous rock surrounded by 4-m thick sections of the Vaqueros Formation.« less

What should health insurance cover? A comparison of Israeli and US approaches to benefit design under national health reform.

2018-04-01

What health insurance should cover and pay for represents one of the most complex questions in national health policy. Israel shares with the US reliance on a regulated insurance market and we compare the approaches of the two countries regarding determining health benefits. Based on review and analysis of literature, laws and policy in the United States and Israel. The Israeli experience consists of selection of a starting point for defining coverage; calculating the expected cost of covered benefits; and creating a mechanism for updating covered benefits within a defined budget. In implementing the Affordable Care Act, the US rejected a comprehensive and detailed approach to essential health benefits. Instead, federal regulators established broadly worded minimum standards that can be supplemented through more stringent state laws and insurer discretion. Notwithstanding differences between the two systems, the elements of the Israeli approach to coverage, which has stood the test of time, may provide a basis for the United States as it renews its health reform debate and considers delegating decisions about coverage to the states. Israel can learn to emulate the more forceful regulation of supplemental and private insurance that characterizes health policy in the United States.

Changes in postural sway as a consequence of wearing a military backpack.

Heller, Michelle F; Challis, John H; Sharkey, Neil A

2009-07-01

Military personnel are often required to carry all of their personal supplies and equipment for long distances during both training and combat situations, creating many biomechanical and postural challenges for these individuals. In addition to other problems such as generalized fatigue and the development of stress fractures, significant external loads may also affect a soldier's postural sway. The purpose of this study was to assess changes in postural sway as a consequence of wearing a military backpack in females. Forty-three female subjects between the ages of 18 and 25 volunteered to participate. There were two conditions: unloaded and while wearing an 18.1 kg military backpack. Each subject stood with two feet on a force platform for 30s under both conditions while center of pressure (COP) data were collected. COP path length increased 64%, medial-lateral excursion increased 131%, anterior-posterior excursion increased 54%, and COP area increased 229% with addition of the backpack (p<0.0001 for all of these measures). These data show that wearing 18.1 kg of external weight in a military backpack increases the postural sway of females, which may in turn increase the likelihood of falls and injury.

A signal-detection analysis of eyewitness identification across the adult lifespan.

2017-05-01

Middle-aged and older adults are frequently victims and witnesses of crime, but knowledge of how identification performance changes over the adult life span is sparse. The authors asked young (18-30 years), middle-aged (31-59 years), and older (60-95 years) adults (N = 2,670) to watch a video of a mock crime and to attempt to identify the culprit from a fair lineup (in which all of the lineup members matched the appearance of the suspect) or an unfair lineup (in which the suspect stood out). They also asked subjects to provide confidence ratings for their identification decisions. To examine identification performance, the authors used a standard response-type analysis, receiver operating characteristic analysis, and signal-detection process modeling. The results revealed that, in fair lineups, aging was associated with a genuine decline in recognition ability-discriminability-and not an increased willingness to choose. Perhaps most strikingly, middle-aged and older adults were generally effective at regulating their confidence judgments to reflect the likely accuracy of their suspect identification decisions. Model-fitting confirmed that the older adults spread their decision criteria such that identifications made with high confidence were likely to be highly accurate, despite the substantial decline in discriminability with age. In unfair lineups, ability to discriminate between innocent and guilty suspects was poor in all age groups. The research enhances theoretical understanding of the ways in which identification behavior changes with age, and has important practical implications for how legal decision-makers should interpret identifications made by middle-aged and older eyewitnesses.

A systematic review of educational interventions to change behaviour of prescribers in hospital settings, with a particular emphasis on new prescribers

PubMed Central

Brennan, Nicola; Mattick, Karen

2013-01-01

Aims Prescribing is a complex task and a high risk area of clinical practice. Poor prescribing occurs across staff grades and settings but new prescribers are attributed much of the blame. New prescribers may not be confident or even competent to prescribe and probably have different support and development needs than their more experienced colleagues. Unfortunately, little is known about what interventions are effective in this group. Previous systematic reviews have not distinguished between different grades of staff, have been narrow in scope and are now out of date. Therefore, to inform the design of educational interventions to change prescribing behaviour, particularly that of new prescibers, we conducted a systematic review of existing hospital-based interventions. Methods Embase, Medline, SIGLE, Cinahl and PsychINFO were searched for relevant studies published 1994–2010. Studies describing interventions to change the behaviour of prescribers in hospital settings were included, with an emphasis on new prescibers. The bibliographies of included papers were also searched for relevant studies. Interventions and effectiveness were classified using existing frameworks and the quality of studies was assessed using a validated instrument. Results Sixty-four studies were included in the review. Only 13% of interventions specifically targeted new prescribers. Most interventions (72%) were deemed effective in changing behaviour but no particular type stood out as most effective. Conclusion Very few studies have tailored educational interventions to meet needs of new prescribers, or distinguished between new and experienced prescribers. Educational development and research will be required to improve this important aspect of early clinical practice. PMID:22831632

To identify patterns of perception of front-of-pack (FOP) nutrition labels and determine dietary, lifestyle and health profiles related to such patterns. Cross-sectional. 28,952 French adults participating in the web-based Nutrinet-Santé cohort. Perception was measured using indicators of understanding and acceptability for three simple FOP labels ("green tick", the logo of the French Nutrition and Health Program and "simple traffic lights" (STL)), and two detailed FOP formats ("multiple traffic lights" (MTL) and "color range" logo (CR)), placed on ready-to-eat soup packages. Dietary intake data were collected using three web-based 24 h records. Associations of perception patterns with individual characteristics, including diet, lifestyle and health status, were examined using analysis of covariance and logistic regression, adjusted for socio-demographic and economic factors. No clear trend emerged concerning differences in dietary intake between perception groups. Low physical activity and obesity were more frequent in the 'favorable to STL' group (respectively, 20.7% and 10.7%). The 'favorable to MTL' group included the highest percentage of individuals who declared type 2 diabetes (2.2%). Persons with hypertension were proportionally more numerous in the 'favorable to MTL' and the 'favorable to CR logo' groups (respectively, 9.5% and 9.3%). After adjustment for socio-demographic and economic factors, no FOP label stood out as being more suitable than another for reaching populations with poor diet. However, both STL and MTL may be most appropriate for increasing awareness of healthy eating among groups at higher risk of nutrition-related chronic diseases.

The neonatal period is associated with high morbidity and mortality in cloned calves. To describe morbidity and mortality in cloned calves from birth to 2 years of age. Thirty-one somatic cell-derived Holstein calves delivered at a veterinary teaching hospital. Medical files were retrospectively analyzed. Four calves were stillborn. Five calves born alive had physical congenital defects. Twenty-three calves had an enlarged umbilical cord. Laboratory abnormalities included acidemia, respiratory acidosis, hyperlactatemia, anemia, stress leukogram, decreased total protein, albumin and globulins, and increased creatinine. Twenty-five calves survived the 1st hour of life. Among them, 11 stood without assistance within 6 hours of birth, 10 calves took longer than 6 hours to stand, and 4 never stood. Twenty-two calves suffered from anorexia. Twelve calves had complications arising from umbilical cord infections. Three calves developed idiopathic hyperthermia (>40°C). Eight calves suffered from gastrointestinal problems, including ruminal distension, abomasal ulcers, neonatal enteritis, intussusception, and abomasal displacement. Mortality between birth and 3 weeks of age was 32% (10/31). Causes of death and reasons for euthanasia included stillbirths, respiratory failure, and limb deformities. Mortality between 3 weeks and 2 years of age was 19% (4/21), with deaths in this group attributed to generalized peritonitis and complications arising from umbilical infections. Overall, mortality rate within 2 years of age was 14/31 (45%). Respiratory problems, limb deformities, and umbilical infections were the most common causes of morbidity and mortality in these cloned calves.

When cognitive load is elevated during a motor task, cortical inhibition and reaction time are increased; yet, standing balance control is often unchanged. This disconnect is likely explained by compensatory mechanisms within the balance system such as increased sensitivity of the vestibulomotor pathway. This study aimed to determine the effects of increased cognitive load on the vestibular control of standing balance. Participants stood blindfolded on a force plate with their head facing left and arms relaxed at their sides for two trials while exposed to continuous electrical vestibular stimulation (EVS). Participants either stood quietly or executed a cognitive task (double-digit arithmetic). Surface electromyography (EMG) and anterior-posterior ground-body forces (APF) were measured in order to evaluate vestibular-evoked balance responses in the frequency (coherence and gain) and time (cumulant density) domains. Total distance traveled for anterior-posterior center of pressure (COP) was assessed as a metric of balance variability. Despite similar distances traveled for COP, EVS-medial gastrocnemius (MG) EMG and EVS-APF coherence and EVS-TA EMG and EVS-MG EMG gain were elevated for multiple frequencies when standing with increased cognitive load. For the time domain, medium-latency peak amplitudes increased by 13-54% for EVS-APF and EVS-EMG relationships with the cognitive task compared to without. Peak short-latency amplitudes were unchanged. These results indicate that reliance on vestibular control of balance is enhanced when cognitive load is elevated. This augmented neural strategy may act to supplement divided cortical processing resources within the balance system and compensate for the acute neuromuscular modifications associated with increased cognitive demand.

Spatial memory is a critical navigation support tool for disoriented evacuees during evacuation under adverse environmental conditions such as dark or smoky conditions. Owing to the complexity of memory, it is challenging to understand the effect of spatial memory on pedestrian evacuation quantitatively. In this study, we propose a simple method to quantitatively represent the evacueeʼs spatial memory about the emergency exit, model the evacuation of pedestrians under the guidance of the spatial memory, and investigate the effect of the evacueeʼs spatial memory on the evacuation from theoretical and physical perspectives. The result shows that (i) a good memory can significantly assist the evacuation of pedestrians under poor visibility conditions, and the evacuation can always succeed when the degree of the memory exceeds a threshold (\\varphi > 0.5); (ii) the effect of memory is superior to that of “follow-the-crowd” under the same environmental conditions; (iii) in the case of multiple exits, the difference in the degree of the memory between evacuees has a significant effect (the greater the difference, the faster the evacuation) for the evacuation under poor visibility conditions. Our study provides a new quantitative insight into the effect of spatial memory on crowd evacuation under poor visibility conditions.

India stood first for millet production in the world and plays a significant role in meat production and consumption too. To meet the demand of health conscious consumers for healthy and nutritious meat food item, the incorporation of millet grains and its byproducts to the meat products by the processors can serve the purpose. The multidimensional positive nutritional and functional characteristics millet grain not only improve the acceptability of the meat products but also increase its own demand as a main coarse food grain in competition to the wheat and rice over the world.

Acquired immunity against malaria as a tool for the control of the disease: the strategy proposed by the Malaria Commission of the League of Nations in 1933.

1998-06-01

The Third General Report of the Malaria Commission, printed in 1933, suggested for the control of malaria a strategy aimed to promote the acquisition of a "relative immunity" through a non radical treatment of the infected people living in highly endemic areas. The paper discusses the content of the Report and describes the scientific (empirical) premises on which it stood. Moreover, it illustrates the criticism that was directed against the immunological strategy and that eventually led to its abandonment.

Simpson grading as predictor of meningioma recurrence.

Meningimas are one of the commonest primary brain tumours and the commonest extra-axial primary brain tumour. Despite better understanding of the molecular pathogenesis of the tumours, surgical excision remains the treatment of choice, and in a large proportion of cases, complete excision is curative. Simpson grading for the extent of resection of meningiomas, was introduced more than six decades ago, and has stood the test of time. With modern technological advancements, however, the relevance of Simpson grading has been questioned. Herein we review the recent literature on the relevance of Simpson grading more than sixty years after its introduction.

Evolution of America's pioneer bacteriologist: George M. Sternberg's formative years.

George M. Sternberg, 1838-1915, M. D., USA, activated modern American bacteriology. He produced the first general bacteriology book in the English language in 1880. His first publications on chemical disinfection (1879) preceded Koch's Sternberg discovered the pneumococcus (1880) before Pasteur did and speculated about phagocytosis (1881) before Metchnikoff. As an experimentalist and author, Sternberg stood "at the head of the American school of working bacteriologists" by the early 1880s. Our essay on Sternberg's evolution as a scientist explains what motivated him and why his early achievements as a bacteriologist, praised by contemporaries, have been underestimated more recently.

After listing functional constraints on what numbers in the brain must do, I sketch the two's complement fixed-point representation of numbers because it has stood the test of time and because it illustrates the non-obvious ways in which an effective coding scheme may operate. I briefly consider its neurobiological implementation. It is easier to imagine its implementation at the cell-intrinsic molecular level, with thermodynamically stable, volumetrically minimal polynucleotides encoding the remembered numbers, than at the circuit level, with plastic synapses encoding them.This article is part of a discussion meeting issue 'The origins of numerical abilities'. © 2017 The Author(s).

An investigation of the relationship between subjective sleep quality, loneliness and mood in an Australian sample: can daily routine explain the links?

PubMed

Smith, Simon Squire; Kozak, Nahum; Sullivan, Karen Anne

2012-03-01

Loneliness and low mood are associated with significant negative health outcomes including poor sleep, but the strength of the evidence underlying these associations varies. There is strong evidence that poor sleep quality and low mood are linked, but only emerging evidence that loneliness and poor sleep are associated. To independently replicate the finding that loneliness and poor subjective sleep quality are associated and to extend past research by investigating lifestyle regularity as a possible mediator of relationships, since lifestyle regularity has been linked to loneliness and poor sleep. Using a cross-sectional design, 97 adults completed standardized measures of loneliness, lifestyle regularity, subjective sleep quality and mood. Loneliness was a significant predictor of sleep quality. Lifestyle regularity was not a predictor of, nor associated with, mood, sleep quality or loneliness. This study provides an important independent replication of the association between poor sleep and loneliness. However, the mechanism underlying this link remains unclear. A theoretically plausible mechanism for this link, lifestyle regularity, does not explain the relationship between loneliness and poor sleep. The nexus between loneliness and poor sleep is unlikely to be broken by altering the social rhythm of patients who present with poor sleep and loneliness.

Prolonged sedentary behavior is an independent risk factor for many negative health outcomes. Although many employers have begun introducing sit-stand desks as means of reducing employee's occupational sitting time, few studies have examined the impact of prolonged access to such desks on sitting/standing time or cardiometabolic outcomes. The present study compared occupational sedentary/physical activity behaviors and cardiometabolic biomarkers among employees with long-term access to traditional sitting and sit-stand desks. This study used a naturalistic, cross-sectional study design. Occupational sedentary and physical activity behaviors and cardiometabolic health outcomes were collected in a controlled laboratory between February and June 2014. Data were analyzed in September 2014. Adults working in full-time sedentary desk jobs who reported having either a sit-stand desk (n=31) or standard sitting desk (n=38) for a minimum of 6 months were recruited. Employees with sit-stand desks sat less (p=0.02) and stood more at work (p=0.01) compared with employees with sitting desks. Significant inverse correlations were observed between several occupational physical activity outcomes (walking time, steps at work) and cardiometabolic risk factors (systolic blood pressure, weight, lean mass, BMI) over the entire sample. Employees with long-term access to sit-stand desks sat less and stood more compared with employees with sitting desks. These findings hold public health significance, as sit-stand desks represent a potentially sustainable approach for reducing sedentary behavior among the large, growing number of sedentary workers at increased risk for sedentariness-related pathologies.

Remote monitoring of patients with heart failure (HF) using wearable devices can allow patient-specific adjustments to treatments and thereby potentially reduce hospitalizations. We aimed to assess HF state using wearable measurements of electrical and mechanical aspects of cardiac function in the context of exercise. Patients with compensated (outpatient) and decompensated (hospitalized) HF were fitted with a wearable ECG and seismocardiogram sensing patch. Patients stood at rest for an initial recording, performed a 6-minute walk test, and then stood at rest for 5 minutes of recovery. The protocol was performed at the time of outpatient visit or at 2 time points (admission and discharge) during an HF hospitalization. To assess patient state, we devised a method based on comparing the similarity of the structure of seismocardiogram signals after exercise compared with rest using graph mining (graph similarity score). We found that graph similarity score can assess HF patient state and correlates to clinical improvement in 45 patients (13 decompensated, 32 compensated). A significant difference was found between the groups in the graph similarity score metric (44.4±4.9 [decompensated HF] versus 35.2±10.5 [compensated HF]; P <0.001). In the 6 decompensated patients with longitudinal data, we found a significant change in graph similarity score from admission (decompensated) to discharge (compensated; 44±4.1 [admitted] versus 35±3.9 [discharged]; P <0.05). Wearable technologies recording cardiac function and machine learning algorithms can assess compensated and decompensated HF states by analyzing cardiac response to submaximal exercise. These techniques can be tested in the future to track the clinical status of outpatients with HF and their response to pharmacological interventions. © 2018 American Heart Association, Inc.

2015-08-01

An induced-pain paradigm has been used in back-healthy people to understand risk factors for developing low back pain during prolonged standing. The purposes of this study were to (1) compare baseline lumbar lordosis in back-healthy participants who do (Pain Developers) and do not (Non-Pain Developers) develop low back pain during 2 h of standing, and (2) examine the relationship between lumbar lordosis and low back pain intensity. Cross-sectional. First, participants stood while positions of markers placed superficial to the lumbar vertebrae were recorded using a motion capture system. Following collection of marker positions, participants stood for 2 h while performing light work tasks. At baseline and every 15 min during standing, participants rated their low back pain intensity on a visual analog scale. Lumbar lordosis was calculated using marker positions collected prior to the 2 h standing period. Lumbar lordosis was compared between pain developers and non-pain developers. In pain developers, the relationship between lumbar lordosis and maximum pain was examined. There were 24 (42%) pain developers and 33 (58%) non-pain developers. Lumbar lordosis was significantly larger in pain developers compared to non-pain developers (Mean difference = 4.4°; 95% Confidence Interval = 0.9° to 7.8°, Cohen's d = 0.7). The correlation coefficient between lumbar lordosis and maximum pain was 0.46 (P = 0.02). The results suggest that standing in more lumbar lordosis may be a risk factor for low back pain development during prolonged periods of standing. Identifying risk factors for low back pain development can inform preventative and early intervention strategies. Copyright © 2015 Elsevier Ltd. All rights reserved.

Impaired decision-making under risk in individuals with alcohol dependence

Background Alcohol dependence is associated with poor decision-making under ambiguity, that is, when decisions are to be made in the absence of known probabilities of reward and loss. However, little is known regarding decisions made by individuals with alcohol dependence in the context of known probabilities (decision under risk). In this study, we investigated the relative contribution of these distinct aspects of decision making to alcohol dependence. Methods Thirty recently detoxified and sober asymptomatic alcohol-dependent individuals, and thirty healthy control participants were tested for decision-making under ambiguity (using the Iowa Gambling Task), and decision-making under-risk (using the Cups Task and Coin Flipping Task). We also tested their capacities for working memory storage (Digit-span Forward), and dual-tasking (Operation-span Task). Results Compared to healthy control participants, alcohol-dependent individuals made disadvantageous decisions on the Iowa Gambling Task, reflecting poor decisions under ambiguity. They also made more risky choices on the Cups and Coin Flipping Tasks reflecting poor decision-making under risk. In addition, alcohol-dependent participants showed some working memory impairments, as measured by the dual tasking, and the degree of this impairment correlated with high-risk decision-making, thus suggesting a relationship between processes sub-serving working memory and risky decisions. Conclusion These results suggest that alcohol dependent individuals are impaired in their ability to decide optimally in multiple facets of uncertainty (i.e., both risk and ambiguity), and that at least some aspects of these deficits are linked to poor working memory processes.

The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitative results about the use of psychoactive substances by truck drivers. Out of these, 28 were carried out in countries with large land areas and 23 obtained their information through self-reporting. The most frequently studied substances were alcohol (n=25), amphetamines (n=17), marijuana (n=16) and cocaine (n=13). The prevalence of the use of these substances greatly varied: alcohol (0.1–91.0%); amphetamines (0.2–82.5%), marijuana (0.2–29.9%), cocaine (0.1–8.3%). The frequency of substance use was lower in studies that investigated the presence of these substances in biological samples than in those based on self-reported use. In 12 studies that evaluated factors associated with the intake of psychoactive substances, the following stood out: younger age, higher income, longer trips, alcohol consumption, driving in the night shift, travelling interstate routes, long or short sleep, fewer hours of rest, little experience of the driver, connection with small and medium sized companies, income below levels determined by labour agreements, productivity-based earnings and prior involvement in accidents. The frequency of psychoactive substance use by truck drivers seems to be high, although that greatly varies according to the type of substance and the method of collecting the information. The use of these substances was mainly associated with indicators of poor working conditions. PMID:24145953

Earth Observations taken by the Expedition 16 Crew

ISS016-E-019239 (29 Dec. 2007) --- Dendi Caldera, Ethiopia is featured in this image photographed by an Expedition 16 crew member on the International Space Station. The Dendi Caldera is located on the Ethiopian Plateau, approximately 86 kilometers to the southwest of Addis Ababa. A caldera is a geological feature formed by the near-total eruption of magma from beneath a volcano, leading to collapse of the volcanic structure into the now-empty magma chamber. This collapse typically leaves a crater or depression where the volcano stood, and later volcanic activity can fill the caldera with younger lavas, ash, pyroclastic rocks, and sediments. While much of the volcanic rock in the area is comprised of basalt erupted as part of the opening of the East African Rift, more silica-rich rock types (characterized by minerals such as quartz and feldspar) are also present. According to scientists, the approximately 4 kilometers wide Dendi Caldera includes some of this silica-rich volcanic rock -- the rim of the caldera, visible in this view, is comprised mainly of poorly-consolidated ash erupted during the Tertiary Period (approximately 65 -- 2 million years ago). A notable feature of the Dendi Caldera is the presence of two shallow lakes formed within the central depression (center). This image also highlights a radial drainage pattern surrounding the remnants of the Dendi volcanic cone. Such patterns typically form around volcanoes, as rainfall has equal potential to move downslope on all sides of the cone and incise channels. No historical volcanic eruptions of Dendi are recorded, however the Wonchi Caldera 13 kilometers to the southwest (not shown) may have been active as "recently" as A.D. 550, say NASA scientists.

This study attempts to understand the nature of violence suffered by the adolescents of Kolkata (erstwhile Calcutta) and to identify its relation with their socio-economic background and mental health variables such as anxiety, adjustment, and self-concept. It is a cross-sectional study covering a total of 370 adolescents (182 boys and 188 girls) from six higher secondary schools in Kolkata. The data was gathered by way of a semi-structured questionnaire and three standard psychological tests. Findings revealed that 52.4%, 25.1%, and 12.7% adolescents suffered psychological, physical, and sexual violence in the last year. Older adolescents (aged 17-18 years) suffered more psychological violence than the younger ones (15-16 years) (p<0.05). Sixty nine (18.6%) adolescent students stood witness to violence between adult members in the family. More than three-fifth (61.9%) adolescents experienced at least one type of violence, while one-third (32.7%) experienced physical or sexual violence or both. Whatever its nature is, violence leaves a scar on the mental health of the victims. Those who have been through regular psychological violence reported high anxiety, emotional adjustment problem, and low self-concept. Sexual abuse left a damaging effect on self-concept (p<0.05), while psychological violence or the witnessing of violence prompted high anxiety scores (p<0.05), poor emotional adjustment (p<0.05), and low self-concept (p<0.05). This study stresses the need to provide individual counselling services to the maltreated adolescents of Kolkata so that their psychological traumas can heal and that they can move on in life with new hopes and dreams.

Objective To identify patterns of perception of front-of-pack (FOP) nutrition labels and determine dietary, lifestyle and health profiles related to such patterns. Design Cross-sectional. Participants/Setting 28,952 French adults participating in the web-based Nutrinet-Santé cohort. Outcome measures Perception was measured using indicators of understanding and acceptability for three simple FOP labels (“green tick”, the logo of the French Nutrition and Health Program and “simple traffic lights” (STL)), and two detailed FOP formats (“multiple traffic lights” (MTL) and “color range” logo (CR)), placed on ready-to-eat soup packages. Dietary intake data were collected using three web-based 24 h records. Statistical analyses Associations of perception patterns with individual characteristics, including diet, lifestyle and health status, were examined using analysis of covariance and logistic regression, adjusted for socio-demographic and economic factors. Results No clear trend emerged concerning differences in dietary intake between perception groups. Low physical activity and obesity were more frequent in the ‘favorable to STL’ group (respectively, 20.7% and 10.7%). The ‘favorable to MTL’ group included the highest percentage of individuals who declared type 2 diabetes (2.2%). Persons with hypertension were proportionally more numerous in the ‘favorable to MTL’ and the ‘favorable to CR logo’ groups (respectively, 9.5% and 9.3%). Conclusions After adjustment for socio-demographic and economic factors, no FOP label stood out as being more suitable than another for reaching populations with poor diet. However, both STL and MTL may be most appropriate for increasing awareness of healthy eating among groups at higher risk of nutrition-related chronic diseases. PMID:24621617

Spotlight: Trinidad and Tobago.

Trinidad and Tobago's major source of income is oil. First discovered in the early 20th century, oil made the country one of the most prosperous in the Western Hemisphere during the 1970s, during which the government had an expansive program of infrastructure improvement. The oil industry also gave rise to the country's famous steel pan music. However, when oil prices collapsed in the 1980s, Trinidad and Tobago fell into a serious recession from which it has only recently emerged. Much of the hope for the economy now lies in natural gas, a significant amount of which is pumped by Amoco. Fertilizers, chemicals, and sugar are other important exports. In the country's 1990 census, East Indians comprised 40% of the population, slightly larger than the population of African descent. Trinidad and Tobago's population has about doubled since the first postwar census in 1946 and population halfway through 1996 stood at 1.3 million. This relatively modest growth of the population is due to a slowly declining birth rate and some emigration although the country receives some immigrants from neighboring islands. The total fertility rate fell to 2.0 in 1995, lower than replacement level, while infant mortality is low and life expectancy is rising to near that of developed countries. There is concern, however, that the poor economy has made health care and medical supplies less accessible. A 1987 Demographic and Health Survey found 53% of all married women using contraception and 44% using modern methods. The level of use has probably increased since then. Finally, Trinidad and Tobago enjoys an excellent education system and the proportion of women age 15 years and older in the labor force is increasing.

Most women with advanced breast cancer (ABC) show little distress, but about one in ten show persistent distress over time. It remains unclear if meanings ascribed by patients to ABC differentiate these distress trajectories. This qualitative study (a) compared illness meanings of ABC between women with persistent psychological distress and those with low/transient distress, and (b) examined how illness meanings might influence coping strategies. The sample was drawn from a prior quantitative study exploring psychological distress trajectories following ABC diagnosis. Overall, 42 Cantonese- or Mandarin-speaking Chinese women diagnosed with locally advanced or metastatic ABC were recruited based on their distress trajectory status (low-stable, transient, or persistent distress). Interviews were recorded, transcribed, and analyzed following grounded theory approach using simultaneous analysis. Women with persistent distress viewed their diagnosis as another blow in life, the illness was global, permeating every aspect of their life. Maladaptive rumination and thought suppression were common responses to illness demands. These women had poor social support. A sense of demoralization stood out in their narratives. In contrast, women with transient/low-stable distress encapsulated the illness, with minimum impacts of their life. They did not evidence dysfunctional repetitive thoughts. Living in a supportive environment, they were able to accept and/or live in the present-moment. Rumination, thought suppression, social constraints, and pre-existing exposure to life stress may be potential risks for chronic distress in response to advanced breast cancer. Persistent and transient distress responses to cancer may have different underpinnings. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Does morphological convergence imply functional similarity? A test using the evolution of quadrupedalism in ornithischian dinosaurs.

PubMed

Maidment, Susannah C R; Barrett, Paul M

2012-09-22

Convergent morphologies are thought to indicate functional similarity, arising because of a limited number of evolutionary or developmental pathways. Extant taxa displaying convergent morphologies are used as analogues to assess function in extinct taxa with similar characteristics. However, functional studies of extant taxa have shown that functional similarity can arise from differing morphologies, calling into question the paradigm that form and function are closely related. We test the hypothesis that convergent skeletal morphology indicates functional similarity in the fossil record using ornithischian dinosaurs. The rare transition from bipedality to quadrupedality occurred at least three times independently in this clade, resulting in a suite of convergent osteological characteristics. We use homology rather than analogy to provide an independent line of evidence about function, reconstructing soft tissues using the extant phylogenetic bracket and applying biomechanical concepts to produce qualitative assessments of muscle leverage. We also optimize character changes to investigate the sequence of character acquisition. Different lineages of quadrupedal ornithischian dinosaur stood and walked differently from each other, falsifying the hypothesis that osteological convergence indicates functional similarity. The acquisition of features correlated with quadrupedalism generally occurs in the same order in each clade, suggesting underlying developmental mechanisms that act as evolutionary constraints.

Did Heisenberg Spit at Max Born?

NASA Astrophysics Data System (ADS)

Lustig, Harry

2005-04-01

In his 1985 book ``The Griffin,'' Arnold Kramish quotes an unnamed ``associate'' of Max Born that when Heisenberg ''was . . . a professor in Göttingen and when the Borns went to visit him, they were met with anti-Jewish sneers and obscenities, and in the end Heisenberg spat on the floor at Max Born's feet!". Kramish, in his own words, states that Heisenberg spat at Born and that the incident took place in 1933. Paul Lawrence Rose places the incident in 1953 and, on the basis of a fuller account from Kramish than the one published, identifies the associate as Born's secretary at Edinburgh University. One may be critical of Heisenberg's character and his behavior under the Nazis, and still be highly skeptical of the Kramish-Rose allegation. The life-long friendship between Born and Heisenberg and the respect which they displayed for each other before, during, and after the Nazi regime, has hardly been challenged by anyone. No known biography of Heisenberg mentions the alleged episode, and none of his obituaries alludes to it. There is no reference to it in Born's autobiography. None of the historians of science, German and American, whom I have consulted credit it. Although it is difficult to prove a negative, it is highly unlikely that Heisenberg spit at Born or on the floor on which they stood.

While several studies have shown that subjects with advanced Parkinson's disease (PD) exhibit abnormalities in sway parameters during quiet standing, abnormalities of postural sway associated with untreated PD have not been reported. Although not clinically apparent, we hypothesized that spontaneous sway in quiet stance is abnormal in people with untreated PD. We examined 13 subjects, recently diagnosed with PD, who were not yet taking any anti-parkinsonian medications and 12 healthy, age-matched control subjects. Postural sway was measured with a linear accelerometer on the posterior trunk (L5 level) and compared with traditional forceplate measures of sway. Subjects stood for two minutes under two conditions: eyes open (EO) and eyes closed (EC). One of the most discriminative measures of postural changes in subjects with untreated PD was the increased ‘JERK’ of lower trunk in the EO condition, measured with the accelerometer. Root mean square and the frequency dispersion of postural sway in the EO condition also discriminated sway in untreated PD subjects compared to controls subjects. We conclude that accelerometer-based sway metrics could be used as objective measures of postural instability in untreated PD. Accelerometer-based analysis of spontaneous sway may provide a powerful tool for early clinical trials and for monitoring the effects of treatment of balance disorders in subjects with PD.

Les liaisons dangereuses: resource surveillance, uranium diplomacy and secret French-American collaboration in 1950s Morocco.

PubMed

Adamson, Matthew

This study explores the origins and consequences of a unique, secret, French-American collaboration to prospect for uranium in 1950s Morocco. This collaboration permitted mediation between the United States and France. The appearance of France in an American-supported project for raw nuclear materials signalled American willingness to accept a new nuclear global order in which the French assumed a new, higher position as regional nuclear ally as opposed to suspicious rival. This collaboration also permitted France and the United States to agree tacitly to the same geopolitical status for the French Moroccan Protectorate, a status under dispute both in Morocco and outside it. The secret scientific effort reassured the French that, whatever the Americans might say publicly, they stood behind the maintenance of French hegemony in the centuries-old kingdom. But Moroccan independence proved impossible to deny. With its foreseeable arrival, the collaboration went from seductive to dangerous, and the priority of American and French geologists shifted from finding a major uranium lode to making sure that nothing was readily available to whatever post-independence interests might prove most powerful. Ultimately, the Kingdom of Morocco took a page out of the French book, using uranium exploration to assert sovereignty over a different disputed territory, its de facto colony of the Western Sahara.

Gaze and viewing angle influence visual stabilization of upright posture

Ustinova, KI; Perkins, J

2011-01-01

Focusing gaze on a target helps stabilize upright posture. We investigated how this visual stabilization can be affected by observing a target presented under different gaze and viewing angles. In a series of 10-second trials, participants (N = 20, 29.3 ± 9 years of age) stood on a force plate and fixed their gaze on a figure presented on a screen at a distance of 1 m. The figure changed position (gaze angle: eye level (0°), 25° up or down), vertical body orientation (viewing angle: at eye level but rotated 25° as if leaning toward or away from the participant), or both (gaze and viewing angle: 25° up or down with the rotation equivalent of a natural visual perspective). Amplitude of participants’ sagittal displacement, surface area, and angular position of the center of gravity (COG) were compared. Results showed decreased COG velocity and amplitude for up and down gaze angles. Changes in viewing angles resulted in altered body alignment and increased amplitude of COG displacement. No significant changes in postural stability were observed when both gaze and viewing angles were altered. Results suggest that both the gaze angle and viewing perspective may be essential variables of the visuomotor system modulating postural responses. PMID:22398978

Heinz Werner: His Life, Ideas, and Contributions to Developmental Psychology in the First Half of the 20th Century.

Ostler, Teresa

2016-01-01

The author provides an overview of Heinz Werner's life and contributions to the field of developmental psychology during the first half of the 20th century. She focuses on his early work in Vienna and Munich as well as his tenure at the Psychological Institute in Hamburg, up through the time when he became a named Professor in Psychology at Clark University. Recognized as one of the founders of developmental psychology, Heinz Werner worked in the areas of perceptual development, comparative psychology, and symbol formation. Versatile in rigorous experimental methodologies, and in observational and phenomenological methodologies, Werner's approach to development stood in contrast to other approaches of development, both past and current. For Werner, development was a heuristic, a way of looking at processes in a variety of domains, including ontogeny, phylogeny, microgenesis, biology, developmental psychopathology, neuropsychology, and comparative psychology. Werner viewed development as proceeding from a state of relative globality and lack of differentiation to a state of increasing differentiation, articulation, and hierarchical integration, but he also stressed that individuals can function at different developmental levels under different times and conditions. Werner's holistic, organismic, comparative, and contextual approach to development transcended interdisciplinary boundaries, allowing him to study the interrelatedness between thought, language, feeling, perception, and culture.

Saudi Arabia.

1986-12-01

In 1985, Saudi Arabia's population stood at 9.6 million, with an annual growth rate of 2.8%. The infant mortality rate was 78/1000 and life expectancy was 60 years. Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development.

The XTiO3 (X = Mn, Fe, Co and Ni) materials with R3c structure could be grown under critical conditions based on first-principles calculations and thermodynamic stability analysis. FeTiO3 and MnTiO3 could be synthesized relatively easily under metal-rich and O-poor conditions, while NiTiO3 could be stable under Ni-rich, O-rich and Ti-poor conditions. The predicted R3c CoTiO3 under thermodynamic equilibrium conditions is suggested to be synthesized under Co-rich, O-rich and Ti-poor conditions, but the calculated phonon dispersion indicates R3c CoTiO3 becomes unstable under the dynamical conditions. The ferroelectric behavior in the XTiO3 (X = Mn, Fe, Co and Ni) system could be dominated by the Ti ion with d0 state and the strong hybridization between Ti and O, while the magnetic property is mainly caused by the contribution of 3d transition metal.

To clarify the effects of altitude acclimatization on postural instability at altitudes, six female climbers stood with their eyes open or closed on a force-measuring platform under normoxia (NC) and hypobaric hypoxia, equivalent to a 5,000 m altitude (HC), before and after an expedition to Mt. Cho-Oyu (8,201 m). The expedition extended over 84 days. We recorded sways in the center of foot pressure, electromyograms (EMGs) of lower-leg muscles, blood components and arterial oxygen saturation (SpO(2)). Before the expedition, the maximum amplitude of sway with the eyes open and integrated EMG from the medial gastrocnemius increased for HC. After the expedition, red blood cell (from 423.4 ± 15.4 to 498.0 ± 24.5 × 10(4) μl(-1)), hemoglobin content (from 12.6 ± 0.32 to 14.5 ± 1.00 g/dl) and 2,3-diphosphoglycerate (from 1.93 ± 0.21 to 2.24 ± 0.34 μmol/ml) increased. The SpO(2) under HC increased from 69.2 ± 9.6 to 77.2 ± 10.0%. The maximum amplitude of sway with the eyes open decreased for HC. No difference in the sway path length and integrated EMGs was observed between NC and HC. These results suggest that acclimatization can improve the impaired postural stability on initial arrival at altitudes. However, it is still unclear how long acclimatization period is needed. Further studies are needed to reveal this point.

Does increased postural threat lead to more conscious control of posture?

Huffman, J L; Horslen, B C; Carpenter, M G; Adkin, A L

2009-11-01

Although it is well established that postural threat modifies postural control, little is known regarding the underlying mechanism(s) responsible for these changes. It is possible that changes in postural control under conditions of elevated postural threat result from a shift to a more conscious control of posture. The purpose of this study was to determine the influence of elevated postural threat on conscious control of posture and to determine the relationship between conscious control and postural control measures. Forty-eight healthy young adults stood on a force plate at two different surface heights: ground level (LOW) and 3.2-m above ground level (HIGH). Centre of pressure measures calculated in the anterior-posterior (AP) direction were mean position (AP-MP), root mean square (AP-RMS) and mean power frequency (AP-MPF). A modified state-specific version of the Movement Specific Reinvestment Scale was used to measure conscious motor processing (CMP) and movement self-consciousness (MSC). Balance confidence, fear of falling, perceived stability, and perceived and actual anxiety indicators were also collected. A significant effect of postural threat was found for movement reinvestment as participants reported more conscious control and a greater concern about their posture at the HIGH height. Significant correlations between CMP and MSC with AP-MP were observed as participants who consciously controlled and were more concerned for their posture leaned further away from the platform edge. It is possible that changes in movement reinvestment can influence specific aspects of posture (leaning) but other aspects may be immune to these changes (amplitude and frequency).

Unexpected medical care spending imposes considerable financial risk on developing country households. Based on managed care models of health insurance in wealthy countries, Colombia’s Régimen Subsidiado is a publicly financed insurance program targeted to the poor, aiming both to provide risk protection and to promote allocative efficiency in the use of medical care. Using a “fuzzy” regression discontinuity design, we find that the program has shielded the poor from some financial risk while increasing the use of traditionally under-utilized preventive services – with measurable health gains.

Anemia is now recognized as a risk factor for a number of adverse outcomes in the elderly, including hospitalization, morbidity, and mortality. What constitutes appropriate evaluation and management for an elderly patient with anemia, and when to initiate a referral to a hematologist, are significant issues. Attempts to identify suggested hemoglobin levels for blood transfusion therapy have been confounded for elderly patients with their co-morbidities. Since no specific recommended hemoglobin threshold has stood the test of time, prudent transfusion practices to maintain hemoglobin thresholds of 9–10 g/dl in the elderly are indicated, unless or until evidence emerges to indicate otherwise.

John Punch, Scotist Holy War, and the Irish Catholic Revolutionary Tradition in the Seventeenth Century.

PubMed

Campbell, Ian W

2016-07-01

During the 1640s, the Irish Franciscan theologian John Punch taught his theology students in Rome that war against Protestants was made just by their religion alone. Jesuits like Luis de Molina identified the holy war tradition in which Punch stood as a Scotist one, and insisted that the Scotists had confused the natural and supernatural spheres. Among Irishmen, Punch was unusual. The main Irish Catholic revolutionary tradition employed Jesuit and Thomist theory. They argued that the Stuarts had lost the right to rule Ireland for natural reasons, not supernatural ones; because the Stuarts were tyrants, not because they were Protestants.

The 'case' of Georg Friedrich NICOLAI, a Berlin physiologist and pacifist, who vehemently stood against a chauvi- nistic academic world in Germany in August 1914, is typical for the academic situation and the role of nationalistic professors as 'mandarines' at German universities and academies at the outbreak of the Great War. NICOLAI suffered a lot from his pacifist internationalism: he was brutally excluded from scientific community, and his academic career was destroyed. Had he not successfully escaped to Denmark, his physical existence would have been endangered as well. On the other hand his dignity was never endangered while NICOLAI successfully resisted military dictatorship and a kind of submissive chauvinism of a perishing Kaiserreich.

Skeletal Fixation in a Mutilated Hand.

2016-11-01

Hand fracture fixation in mutilating injuries is characterized by multiple challenges due to possible skeletal disorganization and concomitant severe injury of soft tissue structures. The effects of skeletal disruption are best analyzed as divided into specific locales in the hand: radial, ulnar, proximal, and distal. Functional consequences of injuries in each of these regions are discussed. Although a variety of implants are now in vogue, K-wire fixation has stood the test of time and is especially useful in multiple fracture situations. Segmental bone loss is quite common in such injuries, which can be safely reconstructed in a staged manner. Copyright © 2016 Elsevier Inc. All rights reserved.

The relationship between recall memory, visual recognition memory, social communication, and the emergence of language skills was measured in a longitudinal study. Thirty typically developing Swedish children were tested at 6, 9 and 14 months. The result showed that, in combination, visual recognition memory at 6 months, deferred imitation at 9 months and turn-taking skills at 14 months could explain 41% of the variance in the infants’ production of communicative gestures as measured by a Swedish variant of the MacArthur Communicative Development Inventories (CDI). In this statistical model, deferred imitation stood out as the strongest predictor. PMID:16886041

Since September 2008, an intervention has made it possible to provide free care to children under five in public health facilities in two districts of Burkina Faso. This study evaluated the intervention's impact on household expenses incurred for services (consultations and medications) to the children targeted. The study is based on a survey of a representative panel of 1,260 households encountered in two waves, one month before and 12 months after the introduction of the intervention. The questions explored the illness episodes of all children under five in the 30 days before each wave. The analysis of health expenses incurred during an illness episode distinguished between total expenses and those incurred in public health facilities (charges for services and medications). Analyses based on multilevel simultaneous equation models were used to estimate the probability of spending and the amount spent, in a context where a large number of observations returned a count of zero. The burden on household expenses was greatly alleviated under the intervention. Average expenditure dropped from US$11 per episode of care to less than US$2 after the intervention was implemented. The risk of incurring an expense at a public health facility was reduced by two-thirds. The facility users' savings were primarily related to medication purchases. In rural areas, where barriers to access health services are more acute, both poor and non-poor families benefited from the intervention. The probability of spending on medications dropped dramatically for both the poor and the non-poor under the exemption (-75% vs.-77%), and the reduction in expenses for medications generated by the intervention was comparable for both groups in relative values (-86% vs.-89%). User fees abolition at the point of service substantially alleviated the burden on household expenses. The intervention benefited both poor and non-poor families and provided financial protection.

Online and offline inferential and textual processing of poor comprehenders: Evidence from a probing method.

Yeari, Menahem; Elentok, Shiri; Schiff, Rachel

2017-03-01

Numerous studies have demonstrated that poor inferential processing underlies the specific deficit of poor comprehenders. However, it is still not clear why poor comprehenders have difficulties in generating inferences while reading and whether this impairment is general or specific to one or more types of inferences. The current study employed an online probing method to examine the spontaneous immediate activation of two inference types-forward-predictive inferences and backward-explanatory inferences-during reading. In addition, we examined the ability of poor comprehenders to retain, suppress, and reactivate text information (relevant for inferencing) in working memory. The participants, 10- to 12-year-old good and poor comprehenders, read short narratives and name inference or text word probes following a predictive, intervening, or bridging sentence. Comparing the size of probe-naming facilitations revealed that poor comprehenders generate predictive inferences, albeit more slowly than good comprehenders, and generate explanatory inferences to a lesser extent than good comprehenders. Moreover, we found that this inferior inferential processing is presumably a result of poor retention and reactivation of inference-evoking text information during reading. Finally, poorer reading comprehension was associated with higher activation of information when it was less relevant following the intervening sentences. Taken together, the current findings demonstrate the manner in which poor regulation of relevant and less relevant information during reading underlies the specific comprehension difficulties experienced by poor comprehenders.

Examining the Effect of Household Wealth and Migration Status on Safe Delivery Care in Urban India, 1992–2006

PubMed Central

2012-01-01

Background Although the urban health issue has been of long-standing interest to public health researchers, majority of the studies have looked upon the urban poor and migrants as distinct subgroups. Another concern is, whether being poor and at the same time migrant leads to a double disadvantage in the utilization of maternal health services? This study aims to examine the trends and factors that affect safe delivery care utilization among the migrants and the poor in urban India. Methodology/Principal Findings Using data from the National Family Health Survey, 1992–93 and 2005–06, this study grouped the household wealth and migration status into four distinct categories poor-migrant, poor-non migrant, non poor-migrant, non poor-non migrant. Both chi-square test and binary logistic regression were performed to examine the influence of household wealth and migration status on safe delivery care utilization among women who had experienced a birth in the four years preceding the survey. Results suggest a decline in safe delivery care among poor-migrant women during 1992–2006. The present study identifies two distinct groups in terms of safe delivery care utilization in urban India – one for poor-migrant and one for non poor-non migrants. While poor-migrant women were most vulnerable, non poor-non migrant women were the highest users of safe delivery care. Conclusion This study reiterates the inequality that underlies the utilization of maternal healthcare services not only by the urban poor but also by poor-migrant women, who deserve special attention. The ongoing programmatic efforts under the National Urban Health Mission should start focusing on the poorest of the poor groups such as poor-migrant women. Importantly, there should be continuous evaluation to examine the progress among target groups within urban areas. PMID:22970324

Electroencephalography (EEG) in the intensive care unit (ICU) is often done to detect non-convulsive seizures (NCS). The outcome of ICU patients with NCS strongly depends on the underlying etiology. The implication of NCS and other EEG findings on clinical outcome independent from their etiology is not well understood and our aim to investigate it. We retrospectively identified all adult patients in the ICU who underwent EEG monitoring between January 2008 and December 2011. The main goals were to define the rate of NCS or non-convulsive status epilepticus (NCSE) occurrence in our center among patients who underwent EEG monitoring and to examine if NCS/NCSE are associated with poor outcome [defined as death or dependence] with and without adjustment for underlying etiology. The rate of poor outcome among different EEG categories were also investigated. During the study period, 177 patients underwent EEG monitoring in our ICU. The overall outcome was poor in 62.7% of those undergoing EEG. The rate of occurrence of NCS/NCSE was 8.5% and was associated with poor outcome in 86.7% with an odds ratio (OR) of 5.1 (95% confidence interval [CI] 1.09-23.8). This association was maintained after adjusting for underlying etiologies with OR 5.6 (95% CI 1.05-29.6). The rate of poor outcome was high in the presence of periodic discharges and sharp and slow waves of 75% and 61.5%, respectively. Our cohort of ICU patients undergoing EEGs had a poor outcome. Those who developed NCS/NCSE experienced an even worse outcome regardless of the underlying etiology. Copyright © 2018 Elsevier B.V. All rights reserved.

Multidimensional poverty and child survival in India.

Mohanty, Sanjay K

2011-01-01

Though the concept of multidimensional poverty has been acknowledged cutting across the disciplines (among economists, public health professionals, development thinkers, social scientists, policy makers and international organizations) and included in the development agenda, its measurement and application are still limited. OBJECTIVES AND METHODOLOGY: Using unit data from the National Family and Health Survey 3, India, this paper measures poverty in multidimensional space and examine the linkages of multidimensional poverty with child survival. The multidimensional poverty is measured in the dimension of knowledge, health and wealth and the child survival is measured with respect to infant mortality and under-five mortality. Descriptive statistics, principal component analyses and the life table methods are used in the analyses. The estimates of multidimensional poverty are robust and the inter-state differentials are large. While infant mortality rate and under-five mortality rate are disproportionately higher among the abject poor compared to the non-poor, there are no significant differences in child survival among educationally, economically and health poor at the national level. State pattern in child survival among the education, economical and health poor are mixed. Use of multidimensional poverty measures help to identify abject poor who are unlikely to come out of poverty trap. The child survival is significantly lower among abject poor compared to moderate poor and non-poor. We urge to popularize the concept of multiple deprivations in research and program so as to reduce poverty and inequality in the population.

Evidence of pre-industrial air pollution from the Heads of the Kings of Juda statues from Notre Dame Cathedral in Paris.

Pollution originating from wood combustion characterised the urban atmospheres of the past and led to the formation of thin grey crusts on the surface of the stone of monuments. The grey crusts discovered on the Heads of the Kings of Juda statues, which adorned the facade of Notre Dame in Paris from the 13th century until 1792, constitute a material record of the effects of this ancient air pollution. The height at which the statues stood suggests that the effect was not the result of a point phenomenon, but was caused by a generalised pollution of the Paris atmosphere at the time.

Lake Chad, Chad as seen from STS-66

NASA Image and Video Library

1994-11-14

This oblique view of Lake Chad was taken by the STS-66 crew in November 1994. This lake lies mainly in the Republic of Chad and partly in Nigeria, Cameroon and Niger. The size of Lake Chad varies seasonally and is actually divided into north and south basins; neither of which is generally more than 25 feet (7.6 meters) deep. In this photograph, all the water appears to be located in the southern basin with the northern and eastern edges of both basins covered with sand dunes which have invaded the area where the water once stood. The prevailing wind direction can be seen from the agriculture burning in both basins to be from the east.

Van Driest transformation and compressible wall-bounded flows

Huang, P. G.; Coleman, G. N.

1994-01-01

The transformation validity question utilizing resulting data from direct numerical simulations (DNS) of supersonic, isothermal cold wall channel flow was investigated. The DNS results stood for a wide scope of parameter and were suitable for the purpose of examining the generality of Van Driest transformation. The Van Driest law of the wall can be obtained from the inner-layer similarity arguments. It was demonstrated that the Van Driest transformation cannot be incorporated to collapse the sublayer and log-layer velocity profiles simultaneously. Velocity and temperature predictions according to the preceding composite mixing-length model were presented. Despite satisfactory congruity with the DNS data, the model must be perceived as an engineering guide and not as a rigorous analysis.

Because of the perpetual development of resistance to current therapies for malaria, the Medicines for Malaria Venture developed the Malaria Box to facilitate the drug development process. We tested the 80 most potent compounds from the box for bilayer-mediated effects on membrane protein conformational changes (a measure of likely toxicity) in a gramicidin-based stopped flow fluorescence assay. Among the Malaria Box compounds tested, four compounds altered membrane properties (p< 0.05); MMV007384 stood out as a potent bilayer-perturbing compound that is toxic in many cell-based assays, suggesting that testing for membrane perturbation could help identify toxic compounds. In any case, MMV007384 should be approached with caution, if at all. PMID:26551613

Nowadays, the mangrove biome is considered to be a profound resource of natural products usually possessing cytotoxicity of a broader range. Covering the period 2007-2015, a total of 21 new naturally occurring compounds has stood out. For example, xylogranin B and swietephragmin C were found to exhibit very potent cytotoxic activity against the colon HCT-116 cells reaching IC 50 values of 0.05 and 0.06 μM, respectively. Bearing in mind the efficacy of the majority compounds in the preliminary in vitro screens, these studies should be expanded to both ex vivo and in vivo screens including the evaluation of the relevant toxicological profiles.

Mitochondria in cancer: not just innocent bystanders.

Frezza, Christian; Gottlieb, Eyal

2009-02-01

The first half of the 20th century produced substantial breakthroughs in bioenergetics and mitochondria research. During that time, Otto Warburg observed abnormally high glycolysis and lactate production in oxygenated cancer cells, leading him to suggest that defects in mitochondrial functions are at the heart of malignant cell transformation. Warburg's hypothesis profoundly influenced the present perception of cancer metabolism, positioning what is termed aerobic glycolysis in the mainstream of clinical oncology. While some of his ideas stood the test of time, they also frequently generated misconceptions regarding the biochemical mechanisms of cell transformation. This review examines experimental evidence which supports or refutes the Warburg effect and discusses the possible advantages conferred on cancer cells by 'metabolic transformation'.

Emergence of the continents

If early degassing of the Earth produced a global ocean several km deep overlying a global sialic crust, then late heavy bombardment of that crust by basin forming impacting bodies would have produced topography such that by 4 billion years ago dry continential landmasses would stand above sea level. From extrapolation of lunar crater statistics, at least 50% of an original global crust on the earth would have been converted into basins averaging 4 km deep after isostatic adjustment. These basins formed the sink into which such a global ocean would drain. If the ocean was initially 2 km deep, then approximately 50% of the early Earth would have stood above sea level when the late heavy bombardment came to a close.

Validity in work-based assessment: expanding our horizons.

Govaerts, Marjan; van der Vleuten, Cees P M

Although work-based assessments (WBA) may come closest to assessing habitual performance, their use for summative purposes is not undisputed. Most criticism of WBA stems from approaches to validity consistent with the quantitative psychometric framework. However, there is increasing research evidence that indicates that the assumptions underlying the predictive, deterministic framework of psychometrics may no longer hold. In this discussion paper we argue that meaningfulness and appropriateness of current validity evidence can be called into question and that we need alternative strategies to assessment and validity inquiry that build on current theories of learning and performance in complex and dynamic workplace settings. Drawing from research in various professional fields we outline key issues within the mechanisms of learning, competence and performance in the context of complex social environments and illustrate their relevance to WBA. In reviewing recent socio-cultural learning theory and research on performance and performance interpretations in work settings, we demonstrate that learning, competence (as inferred from performance) as well as performance interpretations are to be seen as inherently contextualised, and can only be under-stood 'in situ'. Assessment in the context of work settings may, therefore, be more usefully viewed as a socially situated interpretive act. We propose constructivist-interpretivist approaches towards WBA in order to capture and understand contextualised learning and performance in work settings. Theoretical assumptions underlying interpretivist assessment approaches call for a validity theory that provides the theoretical framework and conceptual tools to guide the validation process in the qualitative assessment inquiry. Basic principles of rigour specific to qualitative research have been established, and they can and should be used to determine validity in interpretivist assessment approaches. If used properly, these strategies generate trustworthy evidence that is needed to develop the validity argument in WBA, allowing for in-depth and meaningful information about professional competence. © 2013 John Wiley & Sons Ltd.

2017-02-01

Proprioceptive training on compliant surfaces is used to rehabilitate and prevent ankle sprains. The ability to improve proprioceptive function via such training has been questioned. Achilles tendon vibration is used in motor-control research as a form of proprioceptive stimulus. Using measures of postural steadiness with nonlinear measures to elucidate control mechanisms, tendon vibration can be applied to investigate the underlying rationale of proprioceptive training. To test whether the effect of vibration on young adults' postural control depended on the support surface. Descriptive laboratory study. Research laboratory. Thirty healthy adults and 10 adults with chronic ankle instability (CAI; age range = 18-40 years). With eyes open, participants stood in bilateral stance on a rigid plate (floor), memory foam, and a Both Sides Up (BOSU) ball covering a force platform. We applied bilateral Achilles tendon vibration for the middle 20 seconds in a series of 60-second trials and analyzed participants' responses from previbration to vibration (pre-vib) and from vibration to postvibration (vib-post). We calculated anterior-posterior excursion of the center of pressure and complexity index derived from the area under multiscale entropy curves. The excursion response to vibration differed by surface, as indicated by a significant interaction of P < .001 for the healthy group at both time points and for the CAI group vib-post. Although both groups demonstrated increased excursion from pre-vib and from vib-post, a decrease was observed on the BOSU. The complexity response to vibration differed by surface for the healthy group (pre-vib, P < .001). The pattern for the CAI group was similar but not significant. Complexity changes vib-post were the same on all surfaces for both groups. Participants reacted less to ankle vibration when standing on the BOSU as compared with the floor, suggesting that proprioceptive training may not be occurring. Different balance-training paradigms to target proprioception, including tendon vibration, should be explored.

In this study, we evaluated the survival of Enterococcus faecium and Enterococcus durans, isolated from cheese, in the presence of medications and under simulated in vitro gastrointestinal conditions. The presence of genes encoding virulence factors, the susceptibility to antimicrobial agents, and adhesion properties were also assessed. Enterococcus faecium and E. durans both exhibited resistance to most of the tested medications but showed a large sensitivity to analgesics and antihypertensives; they also showed wide susceptibility to antimicrobial agents. Enterococcus durans SJRP29 had greater resistance to the presence of medications in comparison with the probiotic Lactobacillus acidophilus La-5. The strains, except for E. durans SJRP05, did not harbor virulence genes. Enterococcus durans SJRP14, SJRP17, and SJRP26 were sensitive to all tested antimicrobial agents. Enterococcus faecium was more stable during the simulation of gastrointestinal tract and showed greater viability. At the end of the assay, except for E. durans SJRP17, all strains showed high viability (>7 log cfu/mL). Enterococcus durans SJRP29 stood out from the other strains and was selected for further evaluation; it tolerated up to 3.0% NaCl at 30 and 37°C, besides having good adhesion properties (high values of auto-aggregation, co-aggregation, and hydrophobicity). Additionally, the microorganism did not show bile salt hydrolase activity or mucin degradation. These results encourage carrying out additional tests to evaluate the probiotic features by using in vitro dynamic models and in vivo tests before applying these strains to a food system.

Out from behind the contraceptive Iron Curtain.

PubMed

Jacobson, J L

1990-01-01

In the early 1950s, the Soviet Union and several of its Eastern European satellites completed their transition from high to low fertility before the US and Western Europe. They did this even though there were not enough modern contraceptives available to meet the needs of its citizens. As late as 1990, the Soviet Union had no factories manufacturing modern contraceptives. A gynecologist in Poland described domestically produced oral contraceptives (OCs) as being good for horses, but not for humans. The Romanian government under Ceaucescu banned all contraceptives and safe abortion services. Therefore, women relied on abortion as their principal means of birth control, even in Catholic Poland. The legal abortion rates in the Soviet Union and Romania stood at 100/1000 (1985) and 91/1000 (1987) as compared to 18/1000 in Denmark and 13/1000 in France. All too often these abortion were prohibited and occurred under unsafe conditions giving rise to complications and death. Further, the lack of contraceptives in the region precipitated and increase in AIDS and other sexually transmitted diseases. On the other hand, abortion rates were minimalized in Czechoslovakia, East Germany, and Hungary due to the availability of modern contraceptives and reproductive health services. Hungary and East Germany even manufactured OCs. OC use in these 2 nations rated as among the world's highest. East Germany also treated infertility and sexually transmitted diseases. The region experienced a political opening in latecomer 1989. In 1989, IPPF gave approximately 15 million condoms and 3000 monthly OC packets to the Soviet Union to ease the transition. More international assistance for contraceptive supplies and equipment and training to modernize abortion practices is necessary.

Development and Assessment of Modules to Integrate Quantitative Skills in Introductory Biology Courses.

Redesigning undergraduate biology courses to integrate quantitative reasoning and skill development is critical to prepare students for careers in modern medicine and scientific research. In this paper, we report on the development, implementation, and assessment of stand-alone modules that integrate quantitative reasoning into introductory biology courses. Modules are designed to improve skills in quantitative numeracy, interpreting data sets using visual tools, and making inferences about biological phenomena using mathematical/statistical models. We also examine demographic/background data that predict student improvement in these skills through exposure to these modules. We carried out pre/postassessment tests across four semesters and used student interviews in one semester to examine how students at different levels approached quantitative problems. We found that students improved in all skills in most semesters, although there was variation in the degree of improvement among skills from semester to semester. One demographic variable, transfer status, stood out as a major predictor of the degree to which students improved (transfer students achieved much lower gains every semester, despite the fact that pretest scores in each focus area were similar between transfer and nontransfer students). We propose that increased exposure to quantitative skill development in biology courses is effective at building competency in quantitative reasoning. © 2016 K. Hoffman, S. Leupen, et al.

Mohanty, Sanjay K.

2011-01-01

Background Though the concept of multidimensional poverty has been acknowledged cutting across the disciplines (among economists, public health professionals, development thinkers, social scientists, policy makers and international organizations) and included in the development agenda, its measurement and application are still limited. Objectives and Methodology Using unit data from the National Family and Health Survey 3, India, this paper measures poverty in multidimensional space and examine the linkages of multidimensional poverty with child survival. The multidimensional poverty is measured in the dimension of knowledge, health and wealth and the child survival is measured with respect to infant mortality and under-five mortality. Descriptive statistics, principal component analyses and the life table methods are used in the analyses. Results The estimates of multidimensional poverty are robust and the inter-state differentials are large. While infant mortality rate and under-five mortality rate are disproportionately higher among the abject poor compared to the non-poor, there are no significant differences in child survival among educationally, economically and health poor at the national level. State pattern in child survival among the education, economical and health poor are mixed. Conclusion Use of multidimensional poverty measures help to identify abject poor who are unlikely to come out of poverty trap. The child survival is significantly lower among abject poor compared to moderate poor and non-poor. We urge to popularize the concept of multiple deprivations in research and program so as to reduce poverty and inequality in the population. PMID:22046384

Eat or heat? The effects of poverty on children's behavior.

PubMed

da Fonseca, Marcio A

2014-01-01

In 2011, there were 46.2 million people in the US in poverty (15 percent of the population). The rate for children under 18 years of age was 22 percent, the highest of all age groups. Poverty is strongly linked to adverse socio-emotional outcomes and poor health in children, which influence adult socioeconomic advancement. It affects specific neurocognitive processes disproportionately such as working memory, cognitive control, and especially language and memory. Poor children are frequently exposed to household chaos, maternal depression, neighborhood violence, food insecurity and housing instability. They also experience little social support and have parents who are less responsive, more authoritarian and less involved in school activities than those of higher socioeconomic levels. Their diet is rich in sugar, which may contribute to behavioral disturbances. Children from a disadvantaged background have a poor ability to cope with stress and tend to show aggressive, withdrawn and anxious/depressive behaviors as well as poor academic outcomes. Dental professionals who care for poor children must understand they live under stressful physical and emotional conditions, which will impact their behavior in the dental office.

Background. Previous research has supported gender-specific aetiological factors in oppositional defiant disorder (ODD) and conduct disorder (CD). The aims of this study were to identify gender-specific associations between the behavioural problems-ODD/CD-like problems-and the neurodevelopmental disorders-attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD)-and to investigate underlying genetic effects. Methods. 17,220 twins aged 9 or 12 were screened using the Autism-Tics, AD/HD and other Comorbidities inventory. The main covariates of ODD- and CD-like problems were investigated, and the relative importance of unique versus shared hereditary and environmental effects was estimated using twin model fitting. Results. Social interaction problems (one of the ASD subdomains) was the strongest neurodevelopmental covariate of the behavioural problems in both genders, while ADHD-related hyperactivity/impulsiveness in boys and inattention in girls stood out as important covariates of CD-like problems. Genetic effects accounted for 50%-62% of the variance in behavioural problems, except in CD-like problems in girls (26%). Genetic and environmental effects linked to ADHD and ASD also influenced ODD-like problems in both genders and, to a lesser extent, CD-like problems in boys, but not in girls. Conclusions. The gender-specific patterns should be considered in the assessment and treatment, especially of CD.

The role of mental illness in nonfatal deliberate self-harm (DSH) is controversial, especially in Asian countries. This prospective study examined the role of psychiatric disorders, underlying social and situational problems, and triggers of DSH in a sample of 89 patients hospitalised in primary care hospitals of the Sundarban Delta, India. Data were collected by using a specially designed DSH register, Explanatory Model Interview Catalogue (EMIC), and clinical interview. Psychiatric diagnosis was made following the DSM-IV guidelines. The majority of subjects were young females (74.2%) and married (65.2%). Most of them (69.7%) were uncertain about their “intention to die,” and pesticide poisoning was the commonest method (95.5%). Significant male-female differences were found with respect to education level, occupation, and venue of the DSH attempt. Typical stressors were conflict with spouse, guardians, or in-laws, extramarital affairs, chronic physical illness, and failed love affairs. The major depressive disorder (14.6%) was the commonest psychiatric diagnosis followed by adjustment disorder (6.7%); however 60.7% of the cases had no psychiatric illness. Stressful life situations coupled with easy access to lethal pesticides stood as the risk factor. The sociocultural dynamics behind suicidal behaviour and community-specific social stressors merit detailed assessment and timely psychosocial intervention. These findings will be helpful to design community-based mental health clinical services and community action in the region. PMID:24286067

The ethiopathogenesis of tympanosclerosis has not been completely under- stood yet. Recent studies have shown that free oxygen radicals are important in the formation of tympanosclerosis. Melatonin and Vitamin C are known to be a powerful antioxidant, interacts directly with Reactive Oxygen Species and controls free radical-mediated tissue damage. To demonstrate the possible preventative effects of melatonin and Vitamin C on tympanosclerosis in rats by using histopathology and determination of total antioxidant status total antioxidant status. Standard myringotomy and standard injury were performed in the middle ear of 24 rats. The animals were divided into three groups: Group 1 received melatonin, Group 2 received vitamin C, and Group 3 received saline solution. The mean values of total antioxidant status were similar in the all study groups before the treatment period. The mean values of total antioxidant status were significantly higher in the melatonin and vitamin C groups compared to control group but vitamin C with melatonin groups were similar after the treatment period (p<0.001). Minimum and maximum wall thicknesses were lower in the melatonin and vitamin C groups compared to the control group but the differences were insignificant. Melatonin increases total antioxidant status level and might have some effect on tympanosclerosis that develops after myringotomy.

Each expert received a questionnaire prior to the aforementioned meeting comprising a set of questions concerning therapeutic indications generally applied in the different stages present during muscle repair. The present Consensus Document is the result of the answers to the questionnaire and resulting discussion and consensus over which are the best current indications in the treatment of muscle tears in sport. Avoiding immobilization, not taking nonsteroidal anti-inflammatory drugs (NSAIDs) randomly, fostering early mobilization, increasing vascularization of injured, site and regulating inflammatory mechanisms-without inhibiting these from the early stages of the recovery period-all stood out as main points of the Consensus Document. Additionally, there is controversy concerning cell stimulation techniques and the use of growth factors or cell inhibitors. The decision concerning discharge was unanimous, as was the criteria considered when it came to performing sport techniques without pain.

From "Doctor of Osteopathy" to "Doctor of Osteopathic Medicine": a title change in the push for equality.

PubMed

Gevitz, Norman

2014-06-01

Nationally, the California merger created great solidarity among osteopathic members of state and national osteopathic associations. They rebuffed further efforts at amalgamation and championed the continuation of the DO degree. Even after the American Medical Association (AMA) opened its doors to DOs to join local and state medical associations as well as the AMA itself and gave its blessing to them entering allopathic residency programs and becoming MD board certified, the DOs stood fast for their independence. Yet some across the country wanted to become known as MDs. A few osteopathic physicians even went to federal court to claim-unsuccessfully-that state medical boards' refusal to license them or allow them to identify themselves as MDs violated their constitutional rights under the 1st and 14th Amendments. In the mid-1990s, the American Osteopathic Association (AOA) gave individual osteopathic medical colleges the option of indicating on their diplomas that the DO degree signified "Doctor of Osteopathic Medicine" rather than "Doctor of Osteopathy," a change that paralleled previous AOA policy changes regarding appropriate professional language. Nevertheless, some DOs and particularly a sizable number of osteopathic medical students continued to write of their desire for a change in the degree osteopathic medical colleges awarded. However, in July 2008 the AOA House of Delegates unanimously reaffirmed its commitment to continuing the traditional DO degree. © 2014 The American Osteopathic Association.

Object permanence in young infants: further evidence.

PubMed

Baillargeon, R; DeVos, J

1991-12-01

Recent evidence suggests that 4.5- and even 3.5-month-old infants realize that objects continue to exist when hidden. The goal of the present experiments was to obtain converging evidence of object permanence in young infants. Experiments were conducted using paradigms previously used to demonstrate object permanence in 5.5-month-old infants and 6.5-month-old infants. In one experiment, 3.5-month-old infants watched a short or a tall carrot slide along a track. The track's center was hidden by a screen with a large window in its upper half. The short carrot was shorter than the window's lower edge and so did not appear in the window when passing behind the screen; the tall carrot was taller than the window's lower edge and hence should have appeared in the window but did not. The infants looked reliably longer at the tall than at the short carrot event, suggesting that they (a) represented the existence, height, and trajectory of each carrot behind the screen and (b) expected the tall carrot to appear in the screen window and were surprised that it did not. Control trials supported this interpretation. In another experiment, 4.0-month-old infants saw a toy car roll along a track that was partly hidden by a screen. A large toy mouse was placed behind the screen, either on top or in back of the track. The female infants looked reliably longer when the mouse stood on top as opposed to in back of the track, suggesting that they (a) represented the existence and trajectory of the car behind the screen, (b) represented the existence and location of the mouse behind the screen, and (c) were surprised to see the car reappear from behind the screen when the mouse stood in its path. A second experiment supported this interpretation. The results of these experiments provide further evidence that infants aged 3.5 months and older are able to represent and to reason about hidden objects.

Despite progress in improving health outcomes in Afghanistan by contracting public health services through non-governmental organizations (NGOs), inequity in access persists between the poor and non-poor. This study examined the distributive effect of different contracting types on primary health services provision between the poor and non-poor in rural Afghanistan. Contracts to NGOs were made to deliver a common set of primary care services in each province, with the funding agencies determining contract terms. The contracting approaches could be classified into three contracting out types (CO-1, CO-2 and CO-3) and a contracting-in (CI) approach based on the contract terms, design and implementation. Exit interviews of patients attending randomly sampled primary health facilities were collected through systematic sampling across 28 provinces at two time points. The outcome, the odds that a client attending a health facility is poor, was modelled using logistic regression with a robust variance estimator, and the effect of contracting was estimated using the difference-in-difference approach combined with stratified analyses. The sample covered 5960 interviews from 306 health facilities in 2005 and 2008. The adjusted odds of a poor client attending a health facility over time increased significantly for facilities under CO-1 and CO-2, with odds ratio of 2.82 (1.49, 5.36) P-value 0.001 and 2.00 (1.33, 3.02) P-value 0.001, respectively. The odds ratios for those under CO-3 and CI were not statistically significantly different over time. When compared with the non-contracting facilities, the adjusted ratio of odds ratios of poor status among clients was significantly higher for only those under CO-1, ratio of 2.50 (1.32, 4.74) P-value 0.005. CO-1 arrangement which allows contractors to decide on how funds are allocated within a fixed lump sum with non-negotiable deliverables, and actively managed through an independent government agency, is effective in improving equity of health services provision.

2017-02-01

The Vietnamese government is committed to universal health care largely through social health insurance. The near-poor population is entitled to subsidized but not free insurance under this scheme, but remains under-represented compared to other groups. The aims of this research were to estimate the health insurance coverage of the near-poor in rural Vietnam and identify the individual and household factors associated with health insurance status. Rates of health insurance coverage were estimated from district-level administrative data. A cross-sectional survey was conducted in a representative sample of 2000 near-poor in Cao Lanh district, Dong Thap province, Vietnam. Face-to-face interviews were conducted with a standardized questionnaire. Multiple logistic regression was applied to identify the factors associated with insurance status. The insurance coverage of the near-poor in the selected communities was 20.3%. Enrollment in the health insurance scheme was significantly associated with poor health status (OR = 4.8, 95% CI = 2.4-9.8), good knowledge of health insurance (OR = 4.6, 95% CI = 3.4-6.2), interest in health insurance (OR = 30.1, 95% CI = 11.6-78.0), and the perceived cost of the insurance premium (OR = 2.4, 95% CI = 1.7-3.6). The cost of insurance premiums is a barrier to enrollment. Information, education and communication campaigns together with modified insurance scheme for the near-poor are necessary to enhance insurance coverage in Vietnam.

Nursing Under the Old Poor Law in Midland and Eastern England 1780-1834.

PubMed

King, Steven

2015-10-01

This article uses data drawn from the overseers' accounts and supporting documentation in thirty-six parishes spread over four English counties, to answer three basic questions. First, what was the character, extent, structure, range of activities, and remuneration of the nursing labor force under the Old Poor Law between the late eighteenth century and the implementation of the New Poor Law in the 1830s? Second, were there regional and intra-regional differences in the scale and nature of spending on nursing care for the sick poor? Third, how might one explain such differences? The article suggests that nursing became an increasingly important category of spending for the poor law from the later eighteenth century, but that there were significant variations within and (particularly) between English counties in parochial attitudes toward the provision of nursing for the sick poor. These variations can be explained by applying a matrix of explanatory variables ranging from the minor (differences in how parishes defined "nursing") through to the major (long-standing cultural attitudes toward the responsibility of parishioners to their sick compatriots and the ingrained expectations of the sick poor). The article also throws new light on the hidden aspects of female labor force participation, pointing to the development of professional nursing networks long before the later nineteenth century. © The Author 2014.

A moderator structure is described for a nuclear reactor of the heterogensous type wherein a large mass of moderator is provided with channels therethrough for the introduction of uranium serving as nuclear fuel and for the passage of a cooling fluid. The structure is comprised of blocks of moderator material in superposed horizontal layers, the blocks of each layer being tied together with spaces between them and oriented to have horizontal Wigner growth. The ties are strips of moderator material, the same as the blocks, with transverse Wigner growth, disposed horizontally along lines crossing at vertical axes of the blocks. The blocks are preferably rectangular with a larger or length dimension transverse to the directions of Wiguer growth and are stood on end to provide for horizontal growth.

Burma's gross domestic product was US$6.5 billion in 1984-85, with an annual growth rate of 1-4% and a per capita income of $179. The government aims to establish a centrally controlled economy, although private enterprises have been allowed to operate in the agricultural sector. Economic progress has been hindered by widespread political insurgency and weak markets for export commodities.

Empirical categories: sound, facial, eye and body expressions. sound expressions emphasized laughter. Facial expressions communicated satisfaction and happiness. Eye contact with members stood out in visual expressions. The most frequent body expressions were head movements and indistinct touches. nursing care team members use body language to establish rapport with patients, clarify their needs and plan care. The study classified body language characteristics of humanized care, which involves, in addition to technical, non-technical issues arising from nursing communication.

[John Snow, the cholera epidemic and the foundation of modern epidemiology].

John Snow (1813-1858) was a brilliant British physician. Since young he stood out for his acute observation capacity, logical thinking and perseverance, first in anesthetics and later in epidemiology. The successive outbreaks of cholera that affected London, motivated him to study this disease from a populational point of view. He related the appearance of cases to the consumption of "morbid matter", responsible for the acute diarrhea with dehydration that characterizes this disease. Bravely, Snow opposed to certain theories present at his time, sacrificing his own prestige. He was a pioneer in the use of modern epidemiological investigation methodologies such as conducting surveys and spatial epidemiology. Fairly, he is considered nowadays as father of modern epidemiology by the scientific community.

Summary Recent evidence suggests that poor sleep is a potential pathway underlying the association between stressful experiences and the diurnal cortisol profile. However, existing findings are largely limited to adults. The present study examines whether poor sleep (duration, quality) mediates the relation between stressful experiences and the diurnal cortisol profile in children and adolescents. Children and adolescents (N = 220, Mage = 12.62) provided six saliva samples over two days to derive cortisol indices (bedtime, AUCAG, AUCTG, slopeMAX). Perceived stress, stressful life events, self-reported sleep duration, and sleep quality were measured. Using bootstrapping analyses, sleep quality mediated the relation between perceived stress and AUCTG (R2 = 0.10, F(7, 212) = 3.55, p = .001; 95% BCI[0.09, 1.15]), as well as the relation between stressful life events and AUCTG (R2 = 0.11, F(7, 212) = 3.69, p = .001; 95% BCI[0.40, 3.82]). These mediation models remained significant after adjusting for sleep duration, suggesting that poor sleep quality underlies the association between stressful experiences and the diurnal cortisol profile in children and adolescents. Longitudinal data combined with objectively-measured sleep is essential to further disentangle the complex association between sleep and stress. PMID:25889840

Senate, 59-40, defeats move to strike limits on Medicaid abortion coverage.

PubMed

1993-10-05

On September 24 1993, the US Senate voted to limit access to abortion services for poor women under Medicaid to cases of rape, incest, or where pregnancy poses a risk to a woman's health. The US House of Representatives had earlier adopted a similar amendment, so now the bill will be sent to the President. The original amendment limited abortion access under Medicaid to only poor women whose life was endangered. Its sponsor proposed to expand coverage to cases of rape and incest based on pragmatic political grounds and knowing that this expansion would include fewer than 100 abortions. Abortion rights groups considered this 1993 expansion of the amendment as a step toward restoring real equity in access to abortion. Nevertheless, like the antiabortion groups, they do not consider it progress. The 5 female Senators vowed to fight to obtain full abortion coverage under Medicaid. The also pointed out to their male colleagues that this amendment discriminates against poor women. Many senators voted for the amendment because they chose the lesser of 2 evils. Many people are concerned that this bill indicates how Congress will treat poor women when health care reform legislation arrives and its concern for all women's right to access to abortion services under government-sponsored programs. More than 40 Senators can clearly see the difference between direct federal funding of abortion and other forms of government involvement. Further, Congress did approve the bill granting federal employees access to abortion services, but it passed by only 1 vote. Abortion rights proponents and abortion opponents should consider these aforementioned facts when preparing for the debate over abortion coverage under health care reform.

Efficiency, equity and feasibility of strategies to identify the poor: an application to premium exemptions under National Health Insurance in Ghana.

This paper outlines the potential strategies to identify the poor, and assesses their feasibility, efficiency and equity. Analyses are illustrated for the case of premium exemptions under National Health Insurance (NHI) in Ghana. A literature search in Medline search was performed to identify strategies to identify the poor. Models were developed including information on demography and poverty, and costs and errors of in- and exclusion of these strategies in two regions in Ghana. Proxy means testing (PMT), participatory welfare ranking (PWR), and geographic targeting (GT) are potentially useful strategies to identify the poor, and vary in terms of their efficiency, equity and feasibility. Costs to exempt one poor individual range between US$11.63 and US$66.67, and strategies may exclude up to 25% of the poor. Feasibility of strategies is dependent on their aptness in rural/urban settings, and administrative capacity to implement. A decision framework summarizes the above information to guide policy making. We recommend PMT as an optimal strategy in relative low poverty incidence urbanized settings, PWR as an optimal strategy in relative low poverty incidence rural settings, and GT as an optimal strategy in high incidence poverty settings. This paper holds important lessons not only for NHI in Ghana but also for other countries implementing exemption policies. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Climate policies under wealth inequality.

PubMed

Vasconcelos, Vítor V; Santos, Francisco C; Pacheco, Jorge M; Levin, Simon A

2014-02-11

Taming the planet's climate requires cooperation. Previous failures to reach consensus in climate summits have been attributed, among other factors, to conflicting policies between rich and poor countries, which disagree on the implementation of mitigation measures. Here we implement wealth inequality in a threshold public goods dilemma of cooperation in which players also face the risk of potential future losses. We consider a population exhibiting an asymmetric distribution of rich and poor players that reflects the present-day status of nations and study the behavioral interplay between rich and poor in time, regarding their willingness to cooperate. Individuals are also allowed to exhibit a variable degree of homophily, which acts to limit those that constitute one's sphere of influence. Under the premises of our model, and in the absence of homophily, comparison between scenarios with wealth inequality and without wealth inequality shows that the former leads to more global cooperation than the latter. Furthermore, we find that the rich generally contribute more than the poor and will often compensate for the lower contribution of the latter. Contributions from the poor, which are crucial to overcome the climate change dilemma, are shown to be very sensitive to homophily, which, if prevalent, can lead to a collapse of their overall contribution. In such cases, however, we also find that obstinate cooperative behavior by a few poor may largely compensate for homophilic behavior.

Novel microbial phospholipases A (PLAs) can be found in actinomycetes which have been poorly explored as producers of this activity. To investigate microbial PLA production, efficient methods are necessary such as high-throughput screening (HTS) assays for direct search of PLAs in microbial cultures and cultivation conditions to promote this activity. About 200 strains isolated with selected media for actinomycetes and mostly belonging to Streptomyces (73%) and Micromonospora (10%) genus were first screened on agar-plates containing the fluorophore rhodamine 6G and egg yolk phosphatidylcholine (PC) to detect strains producing phospholipase activity. Then, a colorimetric HTS assay for general PLA activity detection (cHTS-PLA) using enriched PC (≈60%) as substrate and cresol red as indicator was developed and applied; this cHTS-PLA assay was validated with known PLAs. For the first time, actinomycete strains were cultivated by solid-state fermentation (SSF) using PC as inductor and sugar-cane bagasse as support to produce high PLA activity (from 207 to 2,591 mU/g of support). Phospholipase activity of the enzymatic extracts from SSF was determined using the implemented cHTS-PLA assay and the PC hydrolysis products obtained, were analyzed by TLC showing the presence of lyso-PC. Three actinomycete strains of the Streptomyces genus that stood out for high accumulation of lyso-PC, were selected and analyzed with the specific substrate 1,2-α-eleostearoyl- sn -glycero-3-phosphocholine (EEPC) in order to confirm the presence of PLA activity in their enzymatic extracts. Overall, the results obtained pave the way toward the HTS of PLA activity in crude microbial enzymatic extracts at a larger scale. The cHTS-PLA assay developed here can be also proposed as a routine assay for PLA activity determination during enzyme purification,directed evolution or mutagenesis approaches. In addition, the production of PLA activity by actinomycetes using SSF allow find and produce novel PLAs with potential applications in biotechnology.

2016-01-01

Cytoglobin (Cygb) is a vertebrate globin with so far poorly defined function. It is expressed in the fibroblast cell-lineage but has also been found in neurons. Here we provide, using immunohistochemistry, a detailed study on the distribution of Cygb in the mouse brain. While Cygb is a cytoplasmic protein in active cells of the supportive tissue, in neurons it is located in the cytoplasm and the nucleus. We found the expression of Cygb in all brain regions, although only a fraction of the neurons was Cygb-positive. Signals were of different intensity ranging from faint to very intense. Telencephalic neurons in all laminae of the cerebral cortex (CCo), in the olfactory bulb (in particular periglomerular cells), in the hippocampal formation (strongly stained pyramidal cells with long processes), basal ganglia (scattered multipolar neurons in the dorsal striatum, dorsal and ventral pallidum (VP)), and in the amygdala (neurons with unlabeled processes) were labeled by the antibody. In the diencephalon, we observed Cygb-positive neurons of moderate intensity in various nuclei of the dorsal thalamus, in the hypothalamus, metathalamus (geniculate nuclei), epithalamus with strong labeling of habenular nucleus neurons and no labeling of pineal cells, and in the ventral thalamus. Tegmental neurons stood out by strongly stained somata with long processes in, e.g., the laterodorsal nucleus. In the tectum, faintly labeled neurons and fibers were detected in the superior colliculus (SC). The cerebellum exhibited unlabeled Purkinje-neurons but signs of strong afferent cortical innervation. Neurons in the gray matter of the spinal cord showed moderate immunofluorescence. Peripheral ganglia were not labeled by the antibody. The Meynert-fascicle and the olfactory and optic nerves/tracts were the only Cygb-immunoreactive (Cygb-IR) fiber systems. Notably, we found a remarkable level of colocalization of Cygb and neuronal nitric oxide (NO)-synthase in neurons, which supports a functional association. PMID:27199679

Certain socioeconomic factors weakened families and socioeconomic development in the Philippines. 34% of pregnant mothers in 1982 had anemia and by 1987 it increased to 45%. 70.4% of children 6-12 months old and 38.7% of those 12 months were also deficient in iron. Moreover, 12.4% of pregnant women in 1987 had a goiter for a total of 223,200 pregnancies of which likely resulted in spontaneous abortions, fetal death, or cretinism. 20% of newborns weighed 2.5 kg in 1990 so 324,000 newborns began their lives malnourished. Breast feeding fell from 87% in 1983 to 80% in 1984. 17.7% of children 6 years old were malnourished and 67% of them had stunted growth. 23% of elementary school students also were malnourished. Family daily energy intake decreased from the already inadequate level of 1808 calories in 1982 to 1753 in 1987. Similar falls in dietary intakes included protein, carbohydrates, calcium, ascorbic acid, and riboflavin. In 1989, 50% of families were poor thereby limiting their access to health, education, and food. Even though fertility fell from 6.3 in 1970 to 4.5 in 1984, it still was too high. Infant mortality in 1990 stood at 652 which meant that 250 babies died each day. In addition, 70 1-4 year old children died each day. Yet most of these deaths could have been prevented. Pneumonia was responsible for 40% of these child deaths. Other leading causes of death included diarrhea, measles, nutritional deficiencies, and bronchitis. The government has chosen primary health care (PHC) as the means to better the health status of the population, but is had no official policy and PHC committees largely are inactive. The government must seriously implement PHC throughout the Philippines and place health at the top of its list. Cooperation and coordination among all levels of government and nongovernmental organizations must begin.

Elderly fall risk prediction using static posturography

2017-01-01

Maintaining and controlling postural balance is important for activities of daily living, with poor postural balance being predictive of future falls. This study investigated eyes open and eyes closed standing posturography with elderly adults to identify differences and determine appropriate outcome measure cut-off scores for prospective faller, single-faller, multi-faller, and non-faller classifications. 100 older adults (75.5 ± 6.7 years) stood quietly with eyes open and then eyes closed while Wii Balance Board data were collected. Range in anterior-posterior (AP) and medial-lateral (ML) center of pressure (CoP) motion; AP and ML CoP root mean square distance from mean (RMS); and AP, ML, and vector sum magnitude (VSM) CoP velocity were calculated. Romberg Quotients (RQ) were calculated for all parameters. Participants reported six-month fall history and six-month post-assessment fall occurrence. Groups were retrospective fallers (24), prospective all fallers (42), prospective fallers (22 single, 6 multiple), and prospective non-fallers (47). Non-faller RQ AP range and RQ AP RMS differed from prospective all fallers, fallers, and single fallers. Non-faller eyes closed AP velocity, eyes closed VSM velocity, RQ AP velocity, and RQ VSM velocity differed from multi-fallers. RQ calculations were particularly relevant for elderly fall risk assessments. Cut-off scores from Clinical Cut-off Score, ROC curves, and discriminant functions were clinically viable for multi-faller classification and provided better accuracy than single-faller classification. RQ AP range with cut-off score 1.64 could be used to screen for older people who may fall once. Prospective multi-faller classification with a discriminant function (-1.481 + 0.146 x Eyes Closed AP Velocity—0.114 x Eyes Closed Vector Sum Magnitude Velocity—2.027 x RQ AP Velocity + 2.877 x RQ Vector Sum Magnitude Velocity) and cut-off score 0.541 achieved an accuracy of 84.9% and is viable as a screening tool for older people at risk of multiple falls.

Burkina Faso (BF) and Congo Democratic Republic (CDR) are among the top-ten poverty and hunger stricken countries globally. The influence of poverty and hunger on health is enormous. The objectives of the study are to; examine the association between poverty and nutritional status, it also identified socio-demographic and health related mediating factors that contribute to the relationship between poverty and poor nutritional status. The study focused on married or cohabiting women aged 15-49 years and utilized 2010 and 2007 DHS dataset from BF and CDR respectively. Mean age of the women in BF and CDR were 34.4 ± 9.3 and 34.7 ± 9.0 years respectively. About 19.4% and 18.4% of the poor were malnourished as against 7.7% and 9.7% of the rich women in BF and CDR respectively. Obesity and overweight were more prominent among the rich than the poor. Higher prevalence of under-nourish women was found among the older than the younger women in BF. In the countries, the prevalence of malnutrition was significantly higher among women; in the rural areas, with no formal education, anaemic and those who are not working. Multivariate analysis revealed that in the countries, the risk of under-nourishment was significantly higher among poor and middle class than the rich women despite controlling for confounding variables. Undernourished women were more common among the poor and those with no formal education. Programs that target nutrition of women of reproductive age should be strengthened in BF and CDR.

2017-12-01

This project aimed to identify issues patients would like to see improved when interacting with the Minor Injuries Unit (MIU) and as a result generate measurable and feasible Always Events (AEs) based on patient feedback that can be implemented via a Quality Improvement (QI) process. We then looked to assess and improve on the delivery of the agreed AEs to enhance MIU patient experience. AEs were identified by using a short semi-structured survey questionnaire with a free text response section from 45 patients. Patients were asked what should always happen in the ED. Iterative thematic analysis identified information provision and explaining how the department worked as key themes. Two interventions, an educational poster and a video campaign, were designed and implemented to address this issue. Improvement was assessed via convenience sampling of patient questionnaires using a five-point bipolar Likert scale and free text responses which were compared to a set of baseline results via run charts to examine impact of each intervention. A total of 300 patients completed questionnaires throughout the baseline and intervention periods. Baseline results stood at 80% for patient satisfaction regarding information provision, rising to 88% by the end of the poster intervention and 92% by the end of the video intervention. Understanding of how the ED functions stood at 83% in the baseline sample before rising to 86% throughout the poster and video intervention. Composite survey results rose from a baseline level of 82.2% to 86.3% for the poster intervention and 88.8% by the end of the video intervention stage. Patient questionnaires indicated that information provision directly from staff was variable throughout the study period.emermed;34/12/A890-b/F1F1F1Figure 1emermed;34/12/A890-b/F2F2F2Figure 2 DISCUSSION: Implementing the AE approach in the MIU has had a positive effect on patient experience. The poster intervention had the greatest impact on enhancing patient understanding. Our study indicated that direct information provision from staff was sufficient for patients and improvements in responses were due to the project interventions. Next steps should be to further implement the video in the department via inclusion on the patient Wi-Fi homepage and waiting room television to maximise the impact of the video. The patient-staff co-design nature of this study shows the AE methods strength in improving patient-centred care. In summary, this project emphasises that the AE method is an effective, valid and beneficial form of Quality Improvement to be used within EDs which has the potential for widespread future use. © 2017, Published by the BMJ Publishing Group Limited.

2018-06-05

The present study aimed to investigate the sensitivity of detecting lower limb passive motion and use of additional sensory information from fingertip light touch for the postural control of older adults in comparison with young adults. A total of 11 older and 11 young adults (aged 68.1 ± 5.2 and 24.2 ± 2.2 years, respectively) underwent two tasks. We evaluated their sensitivity to passive ankle joint movement while seated in the first task. Participants then stood quietly on a force plate in a semi-tandem stance, for 30 s under two fingertip contact force conditions (no touch and light touch limited to 1 N). The results showed that the threshold of passive ankle displacement and body sway is higher in older adults than in young adults. The body sway reduced for both older and young adults with the addition of light touch at the fingertips. The maximum cross-correlation coefficient and time lags between body sway and fingertip light touch center of pressure was similar between both groups, suggesting that older adults used light touch to reduce body sway, similar to young adults. A higher threshold in detecting passive ankle joint movement may contribute to the increased body sway observed in older adults. These deficits may be compensated by additional sensory cues that would provide enhanced information used to control the upright stance. Copyright © 2018. Published by Elsevier B.V.

[Health care in today's Western Belarus in the inter-war period (1921-1939)].

PubMed

Tiszczenko, E M

2001-01-01

During the inter-war period, today's Western Belarus, which under the Treaty of Riga constituted part of the Second Polish Republic, stood out for its higher morbidity in various disease categories than other regions of the country. Heightened threats of epidemics prevailed in that area, and typhoid fever, trachoma, tuberculois and venereal disease were serious health problems. Specific features of the health care of today's Western Belarus could be observed that set it apart from both that of Eastern Belarus forming a part of the Soviet Union as well as from the central and western provinces of Poland. Compared with Eastern Belarus, there was a lack of health services, including anti-tuberculosis, anti-venereal and paediatric dispensaries, or they were in the process of being created. But physicians' self-government bodies functioned, as did out-patient care with dispensary-like elements and health care provided by local health centres. There also existed the institution of full-time family doctors within the insured health-care system - something lacking in Eastern Belarus. As in other voivodships (provinces) of the Second Republic, there existed multi-sector health care: state, local, insurance-based and private. The Western Belarus had Poland's smallest number of physicians, new hospital beds and pharmacies. On the other hand, today's Western Belarus stands out by virtue of maintaining field-medicine traditions. To this day, assistant medical officers provide health care to the rural population - an arrangement not typical of the central and western provinces fo pre-war Poland.

As the key point in sex hormone analysis, sample pre-treatment technology has attracted scientists' attention all over the world, and the development trend of sample preparation forwarded to faster and more efficient technologies. Taking economic and environmental concerns into account, subcritical fluid extraction as a faster and more efficient method has stood out as a sample pre-treatment technology. This new extraction technology can overcome the shortcomings of supercritical fluid and achieve higher extraction efficiency at relatively low pressures and temperatures. In this experiment, a simple, sensitive and efficient method has been developed for the determination of diethylstilbestrol (DES) in fish tissue using subcritical 1,1,1,2-tetrafluoroethane (R134a) extraction in combination with gas chromatography-mass spectrometry (GC-MS). After extraction, freezing-lipid filtration was utilized to remove fatty co-extract. Further purification steps were performed with C18 and NH2 solid phase extraction (SPE). Finally, the analyte was derived by heptafluorobutyric anhydride (HFBA), followed by GC-MS analysis. Response surface methodology (RSM) was employed to optimizing the extraction condition, and the optimized was as follows: extraction pressure, 4.3 MPa; extraction temperature, 26°C; amount of co-solvent volume, 4.7 mL. Under this condition, at a spiked level of 1, 5, 10 μg kg-1, the mean recovery of DES was more than 90% with relative standard deviations (RSDs) less than 10%. Finally, the developed method has been successfully used to analyzing the real samples.

Anticipatory postural adjustments (APAs) serve to stabilize posture prior to initiation of voluntary movement. This study examined the effects of changes in postural support on APAs using novel and familiar support paradigms. We also investigated whether postural strategies were refined with practice and how the CNS responded when multiple supports were available. Twelve healthy subjects stood on dual force platforms and performed 20 randomized left and right rapid leg-lift tasks in response to a visual cue under four conditions: unsupported, bilateral handgrip, bite plate, and a combined handgrip and bite plate condition. Vertical ground reaction forces, electromyography of limb, trunk and jaw muscles, and forces exerted on the support apparatus were recorded. Shift in center-of-pressure amplitude and duration were reduced with increased support. Muscles were recruited in advance of the focal movement when able to contribute to stability, and activity was modulated based on the amount of support available. The CNS adapted anticipatory postural strategies immediately with changes in condition regardless of familiarity with the support; however, adaptation was only complete at the first repetition in conditions that involved familiar support strategies. Tasks that involved a novel bite strategy continued to adapt with practice. In the multiple support condition, both hand and bite strategies were immediately incorporated; however, the contribution of each was not identical to conditions where supports were provided individually. This study emphasizes the flexibility of the CNS to organize postural strategies to meet the demands of postural stability in both familiar and novel situations.

NASA image acquired December 21, 2011 The rugged landscape of the Canary Islands stood out in sharp contrast to the smooth blue waters of the Atlantic Ocean and the flat tan land of northwestern Africa on December 21, 2011, when the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite captured this true-color image. The Canary Islands are a group of seven large islands and several smaller islets, all volcanic in origin. The eastern edge of the chain lies only 100 kilometers from the coasts of Morocco and Western Sahara, and the chain stretches for about 500 kilometers across the Atlantic. All the islands are mountainous, and Tenerife, the central island in this image is home to Pico de Teinde, the highest peak, which rises 12,198 feet (3,718 meters) above sea level. From east to west, the islands are named Lanzarote, Fuerteventura, Gran Canaria, Tenerife, La Gomera, La Palmera and El Hierro. A bright swirl of peacock blue marks the ocean south of El Hierro, a stain on the sea from an ongoing eruption of a volcano under the waters.

Type 1 diabetes is a chronic autoimmune disease in which pancreatic beta cells are killed by the infiltrating immune cells as well as the cytokines released by these cells. Many studies indicate that inflammatory mediators have an essential role in this disease. In the present study, we profiled the transcriptome in human islets of langerhans under control conditions or following exposure to the pro-inflammatory cytokines based on the RNA sequencing dataset downloaded from SRA database. After filtered the low-quality ones, the RNA readers was aligned to human genome hg19 by TopHat and then assembled by Cufflinks. The expression value of each transcript was calculated and consequently differentially expressed genes were screened out. Finally, a total of 63 differentially expressed genes were identified including 60 up-regulated and three down-regulated genes. GBP5 and CXCL9 stood out as the top two most up-regulated genes in cytokines treated samples with the log2 fold change of 12.208 and 10.901, respectively. Meanwhile, PTF1A and REG3G were identified as the top two most down-regulated genes with the log2 fold change of -3.759 and -3.606, respectively. Of note, we also found 262 lncRNAs (long non-coding RNA), 177 of which were inferred as novel lncRNAs. Further in-depth follow-up analysis of the transcriptional regulation reported in this study may shed light on the specific function of these lncRNA.

Aging is a critical factor to influence the functional performance during daily life. Without an appropriate posture control response when experiencing an unexpected external perturbation, fall may occur. A novel six-degree-of freedom platform with motion control protocol was designed to provide a real-life simulation of unexpected disturbance in order to discriminate the age-related changes of the balance control and the recovery ability. Twenty older adults and 20 healthy young adults participated in the study. The subjects stood barefoot on the novel movable platform, data of the center of mass (COM) excursion, joint rotation angle and electromyography (EMG) were recorded and compared. The results showed that the older adults had similar patterns of joint movement and COM excursion as the young adults during the balance reactive-recovery. However, larger proximal joint rotation in elderly group induced larger COM sway envelop and therefore loss of the compensatory strategy of posture recovery. The old adults also presented a lower muscle power. In order to keep an adequate joint stability preventing from falling, the EMG activity was increased, but the asymmetric pattern might be the key reason of unstable postural response. This novel design of moveable platform and test protocol comprised the computerized dynamic posturography (CDP) demonstrate its value to assess the possible sensory, motor, and central adaptive impairments to balance control and could be the training tool for posture inability person. © 2013 Elsevier Ltd.

Investigating “mass hysteria” in early postcolonial Uganda: Benjamin H. Kagwa, East African psychiatry, and the Gisu

PubMed Central

Pringle, Yolana

2016-01-01

In the early 1960s, medical officers and administrators began to receive reports of what was being described as “mass madness” and “mass hysteria” in Tanganyika (now Tanzania) and Uganda. Each epidemic reportedly affected between 300 and 600 people and, coming in the wake of independence from colonial rule, caused considerable concern. One of the practitioners sent to investigate was Benjamin H. Kagwa, a Ugandan-born psychiatrist whose report represents the first investigation by an African psychiatrist in East Africa. This article uses Kagwa’s investigation to explore some of the difficulties facing East Africa’s first generation of psychiatrists as they took over responsibility for psychiatry. During this period, psychiatrists worked in an intellectual climate that was both attempting to deal with the legacy of colonial racism, and which placed faith in African psychiatrists to reveal more culturally sensitive insights into African psychopathology. The epidemics were the first major challenge for psychiatrists such as Kagwa precisely because they appeared to confirm what colonial psychiatrists had been warning for years—that westernization would eventually result in mass mental instability. As this article argues, however, Kagwa was never fully able to free himself from the practices and assumptions that had pervaded his discipline under colonial rule. His analysis of the epidemics as a “mental conflict” fit into a much longer tradition of psychiatry in East Africa, and stood starkly against the explanations of the local community. PMID:24191308

The Development of Infants’ use of Property-poor Sounds to Individuate Objects

Wilcox, Teresa; Smith, Tracy R.

2010-01-01

There is evidence that infants as young as 4.5 months use property-rich but not property-poor sounds as the basis for individuating objects (Wilcox et al., 2006). The current research sought to identify the age at which infants demonstrate the capacity to use property-poor sounds. Using the task of Wilcox et al., infants aged 7 and 9 months were tested. The results revealed that 9- but not 7-month-olds demonstrated sensitivity to property-poor sounds (electronic tones) in an object individuation task. Additional results confirmed that the younger infants were sensitive to property-rich sounds (rattle sounds). These are the first positive results obtained with property-poor sounds in infants and lay the foundation for future research to identify the underlying basis for the developmental hierarchy favoring property-rich over property-poor sounds and possible mechanisms for change.

Poor comprehenders in the classroom: teacher ratings of behavior in children with poor reading comprehension and its relationship with individual differences in working memory.

PubMed

Pimperton, Hannah; Nation, Kate

2014-01-01

Differing etiological explanations have been proposed to account for poor comprehenders' difficulties with reading comprehension, with some researchers emphasizing working memory deficits and others arguing for oral language weaknesses playing a key causal role. The authors contrasted these two theoretical accounts using data obtained from direct measures of working memory and from teacher ratings of poor comprehenders' behavior in the classroom. At the group level, poor comprehenders showed weaknesses on verbal but not nonverbal working memory tasks, in keeping with the "language account." However, they also showed evidence of elevated levels of problem behaviors specifically associated with working memory deficits. Further analysis revealed that these group differences in working-memory-related problem behaviors were carried by a small subgroup of poor comprehenders who also displayed domain-general (verbal and nonverbal) working memory problems, argued to be reflective of "genuine" underlying working memory deficits.

Balancing personal maintenance with parental investment in a chick-rearing seabird: physiological indicators change with foraging conditions.

Seabird parents use a conservative breeding strategy that favours long-term survival over intensive parental investment, particularly under harsh conditions. Here, we examine whether variation in several physiological indicators reflects the balance between parental investment and survival in common murres ( Uria aalge ) under a wide range of foraging conditions. Blood samples were taken from adults during mid-chick rearing from 2007 to 2014 and analysed for corticosterone (CORT, stress hormone), beta-hydroxybutyrate (BUTY, lipid metabolism reflecting ongoing mass loss), and haematocrit (reflecting blood oxygen capacity). These measures, plus body mass, were related to three levels of food availability (good, intermediate, and poor years) for capelin, the main forage fish for murres in this colony. Adult body mass and chick-feeding rates were higher in good years than in poor years and heavier murres were more likely to fledge a chick than lighter birds. Contrary to prediction, BUTY levels were higher in good years than in intermediate and poor years. Murres lose body mass just after their chicks hatch and these results for BUTY suggest that mass loss may be delayed in good years. CORT levels were higher in intermediate years than in good or poor years. Higher CORT levels in intermediate years may reflect the necessity of increasing foraging effort, whereas extra effort is not needed in good years and it is unlikely to increase foraging success in poor years. Haematocrit levels were higher in poor years than in good years, a difference that may reflect either their poorer condition or increased diving requirements when food is less available. Our long-term data set provided insight into how decisions about resource allocation under different foraging conditions are relating to physiological indicators, a relationship that is relevant to understanding how seabirds may respond to changes in marine ecosystems as ocean temperatures continue to rise.

Leaning to the left makes the Eiffel Tower seem smaller: posture-modulated estimation.

In two experiments, we investigated whether body posture influences people's estimation of quantities. According to the mental-number-line theory, people mentally represent numbers along a line with smaller numbers on the left and larger numbers on the right. We hypothesized that surreptitiously making people lean to the right or to the left would affect their quantitative estimates. Participants answered estimation questions while standing on a Wii Balance Board. Posture was manipulated within subjects so that participants answered some questions while they leaned slightly to the left, some questions while they leaned slightly to the right, and some questions while they stood upright. Crucially, participants were not aware of this manipulation. Estimates were significantly smaller when participants leaned to the left than when they leaned to the right.

The population of Yemen stood at 2.02 million in 1984, with an annual growth rate of 2.9%. The infant mortality rate is 137/1000; life expectancy is 46 years. The literacy rate is 32%. The work force of 410,000 is distributed as follows: agriculture and fisheries, 43.8%; industry and commerce, 28%; and services, 28%. In 1984, the gross national product in Yemen was US$1130 million, with an average real growth rate of 7.4% in 1973-83. In 1978, the 3 political parties were amalgamated into the Yemen Socialist Party, which became the only legal party. Until 1982, economic policy was focused on infrastructure development and agricultural self-sufficiency; since that time, there have been efforts to discover and produce oil. Most of the people of Yemen are subsistence farmers or nomadic herders.

The overall aim of this paper was to compare the multielement composition and antioxidant capacity of two Montenegrin Merlot wines obtained from specific vine clones (VCR1 and VCR 101) along with commercial Merlot wine throughout the consecutive vintages in 2010 and 2011. Elemental composition was analysed using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). Additionally, antioxidant capacity was assessed by cyclic voltammetry. VCR 1 wine from 2011 stood out for its elemental composition. On the other hand, antioxidant capacity of VCR 101 wines was the highest one for the both vintages. According to the experimental data obtained, all three wines are good source of essential elements and products with a significant antioxidant activity and specific geographical origin.

Inflammation is a complex event linked to tissue damage whether by bacteria, physical trauma, chemical, heat or any other phenomenon. This physiological response is coordinated largely by a variety of chemical mediators that are released from the epithelium, the immunocytes and nerves of the lamina propria. However, if the factor that triggers the inflammation persists, the inflammation can become relentless, leading to an intensification of the lesion. The present work is a literature survey of plant extracts from the South American continent that have been reported to show anti-inflammatory activity. This review refers to 63 bacterial families of which the following stood out: Asteraceae, Fabaceae, Euphorbiaceae, Apocynaceae and Celastraceae, with their countries, parts used, types of extract used, model bioassays, organisms tested and their activity.

With the objective of describing mortality from traffic accidents in Bayamo, Cuba, in 2011 a review was performed of injured and deceased patients due to traffic accidents, recorded in the Hospital Carlos M. de Céspedes. Of the 1,365 injured patients treated in the emergency room, the predominant groups were individuals aged 25 to 44 years comprising 372 patients (27.3%) and men comprising 1,071 (78.5%). 46 people died, most from the same age group and male. Multiple traumatisms (52.6%) and craniofacial trauma (34.2%) were the predominant injuries. Motor vehicle-pedestrian accidents stood out with a mortality of 26.3%. In conclusion, mortality from traffic accidents predominately occurs in young male adults, whose fatal consequences are due to multiple traumatisms from road accidents.

Almost all of those detained were later released on bail and stood trials before different branches of the Tehran Revolutionary Court, and court of appeals. All sessions and hearings were held behind closed doors! Final verdicts have been gradually delivered, but the judiciary refuses to enforce the sentences, drop the charges, or return the bails. The whole case has been turned into a Sword of Damocles held over the heads of all political activists who happen to be critical of the system.

A little over ten years ago, in the early morning hours of May 4, 2002, crowds of spectators stood anxiously watching as the Delta II rocket carrying NASA's Aqua spacecraft lifted off from its launch pad at Vandenberg Air Force Base in California at 2:55 a.m. The rocket quickly went through a low-lying cloud cover, after which the main portion of the rocket fell to the waters below and the rockets second stage proceeded to carry Aqua south across the Pacific, onward over Antarctica, and north to Africa, where the spacecraft separated from the rocket 59.5 minutes after launch. Then, 12.5 minutes later, the solar array unfurled over Europe, and Aqua was on its way in the first of what by now have become over 50,000 successful orbits of the Earth.

Indian cress (Tropaeolum majus L.) absolute was studied by GC-olfactometry (VIDEO-Sniff method) in order to identify odor-active aroma compounds. Because of its fruity-sulfury odor note, a compound that has never been identified in plant extracts before stood out: O,S-diethyl thiocarbonate, present at 0.1% (percentage of the total GC/FID area) in the extract. GCxGC-TOFMS allowed for a clean mass spectrum to be obtained, and isolation by preparative GC followed by NMR studies allowed its identification. Here, we report on the first detection of O,S-diethyl thiocarbonate in Indian cress absolute by GC-olfactometry/VIDEO-Sniff and on its isolation and identification. The synthesis and odor evaluation of its homologues are presented.

Evolutionary psychology and intelligence research.

Kanazawa, Satoshi

2010-01-01

This article seeks to unify two subfields of psychology that have hitherto stood separately: evolutionary psychology and intelligence research/differential psychology. I suggest that general intelligence may simultaneously be an evolved adaptation and an individual-difference variable. Tooby and Cosmides's (1990a) notion of random quantitative variation on a monomorphic design allows us to incorporate heritable individual differences in evolved adaptations. The Savanna-IQ Interaction Hypothesis, which is one consequence of the integration of evolutionary psychology and intelligence research, can potentially explain why less intelligent individuals enjoy TV more, why liberals are more intelligent than conservatives, and why night owls are more intelligent than morning larks, among many other findings. The general approach proposed here will allow us to integrate evolutionary psychology with any other aspect of differential psychology. Copyright 2010 APA, all rights reserved.

The agreement between clinician- and patient-reported toxicities and their association with poor tolerance to therapy were assessed in an older population receiving curative radiotherapy (RT). Patients ≥ 65 years old with newly-diagnosed head and neck or lung cancer receiving curative RT ± chemotherapy were enrolled on a prospective, observational study. Agreement between clinician (CTCAEv4.02) and patient (PRO-CTCAE, EORTC QLQ-C30) report of toxicities were assessed at baseline, during treatment, and post-treatment. The association of clinician- and patient-reported symptoms with poor tolerance to therapy (defined as hospitalization, >3-day treatment delay, change in treatment regimen, or death) was assessed. Among 45 patients, median age was 71, 60% had head and neck cancer, and 47% received concurrent chemotherapy with RT. In comparing CTCAE vs PRO-CTCAE, there was good agreement at baseline except for fatigue, anorexia, and pain, where clinicians under-reported the severity. The discrepancy increased during treatment with clinicians reporting lower severity in ≥50% of matched pairs for 4/10 symptoms assessed. At follow-up, clinicians under-reported severity in ≥50% of pairs for 7/10 symptoms. CTCAE vs EORTC QLQ-C30 mirrored these findings. Patient-reported symptoms of nausea and dysphagia at 2 weeks and clinician-observed symptoms of nausea and dysphagia at 4 weeks were associated with poor tolerance to therapy. Clinicians under-report toxicities during and after curative RT in older patients with head and neck or lung cancer. Select toxicities reported by patients early in treatment and clinicians later in treatment were associated with poor tolerance to cancer therapy, providing valuable complementary information.

The promotion of cooperation by the poor in dynamic chicken games

2017-02-01

The evolution of cooperative behavior is one of the most important issues in game theory. Previous studies have shown that cooperation can evolve only under highly limited conditions, and various modifications have been introduced to games to explain the evolution of cooperation. Recently, a utility function basic to game theory was shown to be dependent on current wealth as a conditional (state) variable in a dynamic version of utility theory. Here, we introduce this dynamic utility function to several games. Under certain conditions, poor players exhibit cooperative behavior in two types of chicken games (the hawk-dove game and the snowdrift game) but not in the prisoner’s dilemma game and the stag hunt game. This result indicates that cooperation can be exhibited by the poor in some chicken games. Thus, the evolution of cooperation may not be as limited as has been suggested in previous studies.

Changes in Child Mortality Over Time Across the Wealth Gradient in Less-Developed Countries

PubMed Central

2014-01-01

BACKGROUND: It is unknown whether inequalities in under-5 mortality by wealth in low- and middle-income countries (LMICs) are growing or declining. METHODS: All Demographic and Health Surveys conducted between 2002 and 2012 were used to measure under-5 mortality trends in 3 wealth tertiles. Two approaches were used to estimate changes in under-5 mortality: within-survey changes from all 54 countries, and between-survey changes for 29 countries with repeated survey waves. The principal outcome measures include annual decline in mortality, and the ratio of mortality between the poorest and least-poor wealth tertiles. RESULTS: Mortality information in 85 surveys from 929 224 households and 1 267 167 women living in 54 countries was used. In the subset of 29 countries with repeat surveys, mortality declined annually by 4.36, 3.36, and 2.06 deaths per 1000 live births among the poorest, middle, and least-poor tertiles, respectively (P = .031 for difference). The mortality ratio declined from 1.68 to 1.48 during the study period (P = .006 for trend). In the complete set of 85 surveys, the mortality ratio declined in 64 surveys (from 2.11 to 1.55), and increased in 21 surveys (from 1.58 to 1.88). Multivariate analyses suggest that convergence was associated with good governance (P ≤ .03 for 4 governance indicators: government effectiveness, rule of law, regulatory quality, and control of corruption). CONCLUSIONS: Overall, under-5 mortality in low- and middle-income countries has decreased faster among the poorest compared with the least poor between 1995 and 2012, but progress in some countries has lagged, especially with poor governance.

Protein energy malnutrition in India: the plight of our under five children.

PubMed

Bhutia, Dechenla Tshering

2014-01-01

Protein energy malnutrition (PEM) is a major public health problem in India. This affects the child at the most crucial period of time of development, which can lead to permanent impairment in later life. PEM is measured in terms of underweight (low weight for age), stunting (low height for age) and wasting (low weight for height). The prevalence of stunting among under five is 48% and wasting is 19.8% and with an underweight prevalence of 42.5%, it is the highest in the world. Undernutrition predisposes the child to infection and complements its effect in contributing to child mortality. Lalonde model (1974) is used to look into the various determinants of PEM in under five children and its interrelation in causation of PEM. The determinants of PEM are broadly classified under four distinct categories: Environmental factors including the physical and social environment, behavioral factors, health-care service related and biological factors. The socio-cultural factors play an important role wherein, it affects the attitude of the care giver in feeding and care practices. Faulty feeding practice in addition to poor nutritional status of the mother further worsens the situation. The vicious cycle of poor nutritional status of the mother leading to low birth weight child further exposes the child to susceptibility to infections which aggravates the situation. However, it is seen that percapita income of the family did not have much bearing on the poor nutritional status of the child rather lack of proper health-care services adversely contributed to poor nutritional status of the child. PEM is a critical problem with many determinants playing a role in causing this vicious cycle of undernutrition. With almost half of under five children undernourished in India, the Millennium Development Goal (MDG) of halving the prevalence of underweight by 2015 seems a distant dream.

J Physiol 592: 3671-3685, 2014) and kinematic (Osler CJ, Tersteeg MC, Reynolds RF, Loram ID. Eur J Neurosci 38: 3239-3247, 2013) data. We examined the effect of threat of perturbation, a different form of postural threat, on coupling (cross-correlation, coherence, and gain) of the vestibulo-muscular relationship in 25 participants who maintained standing balance. In the "No-Threat" conditions, participants stood quietly on a stable surface. In the "Threat" condition, participants' balance was threatened with unpredictable mediolateral support surface tilts. Quiet standing immediately before the surface tilts was compared to an equivalent time from the No-Threat conditions. Surface EMG was recorded from bilateral trunk, hip, and leg muscles. Hip and leg muscles exhibited significant increases in peak cross-correlation amplitudes, coherence, and gain (1.23-2.66×) in the Threat condition compared with No-Threat conditions, and significant correlations were observed between threat-related changes in physiological arousal and medium-latency peak cross-correlation amplitude in medial gastrocnemius (r = 0.408) muscles. These findings show a clear threat effect on vestibular-evoked responses in muscles in the lower body, with less robust effects of threat on trunk muscles. Combined with previous work, the present results can provide insight into observed changes during balance control in threatening situations. This is the first study to show increases in vestibular-evoked responses of the lower body muscles under conditions of increased threat of postural perturbation. While robust findings were observed in hip and leg muscles, less consistent results were found in muscles of the trunk. The present findings provide further support in the ongoing debate for arguments that vestibular-evoked balance responses are influenced by fear and anxiety and explain previous threat-related changes in balance.

Lubetzky, Anat Vilnai; McCoy, Sarah Westcott; Price, Robert; Kartin, Deborah

2017-01-01

Context: Proprioceptive training on compliant surfaces is used to rehabilitate and prevent ankle sprains. The ability to improve proprioceptive function via such training has been questioned. Achilles tendon vibration is used in motor-control research as a form of proprioceptive stimulus. Using measures of postural steadiness with nonlinear measures to elucidate control mechanisms, tendon vibration can be applied to investigate the underlying rationale of proprioceptive training. Objective: To test whether the effect of vibration on young adults' postural control depended on the support surface. Design: Descriptive laboratory study. Setting: Research laboratory. Patients or Other Participants: Thirty healthy adults and 10 adults with chronic ankle instability (CAI; age range = 18−40 years). Intervention(s): With eyes open, participants stood in bilateral stance on a rigid plate (floor), memory foam, and a Both Sides Up (BOSU) ball covering a force platform. We applied bilateral Achilles tendon vibration for the middle 20 seconds in a series of 60-second trials and analyzed participants' responses from previbration to vibration (pre-vib) and from vibration to postvibration (vib-post). Main Outcome Measure(s): We calculated anterior-posterior excursion of the center of pressure and complexity index derived from the area under multiscale entropy curves. Results: The excursion response to vibration differed by surface, as indicated by a significant interaction of P < .001 for the healthy group at both time points and for the CAI group vib-post. Although both groups demonstrated increased excursion from pre-vib and from vib-post, a decrease was observed on the BOSU. The complexity response to vibration differed by surface for the healthy group (pre-vib, P < .001). The pattern for the CAI group was similar but not significant. Complexity changes vib-post were the same on all surfaces for both groups. Conclusions: Participants reacted less to ankle vibration when standing on the BOSU as compared with the floor, suggesting that proprioceptive training may not be occurring. Different balance-training paradigms to target proprioception, including tendon vibration, should be explored. PMID:28125270

In this issue, ASK writers explore ways to maintain their balance in their field of Project Management, and even what happens when they don't. From his own experiences. Colby Africa learned that pushing too hard can take a personal toll, even though his project was a success in the end. He looked back and asked himself. At what personal cost? Sometimes one of the most simple - and the most human way - of keeping oneself grounded is not to lose your sense of humor. Ray Morgan's story about a test flight gone bad tells how the sound of their model crashing to the ground was followed by the test team's hysterical laughter. The story, you will see, is much deeper. But the message in the example? Sometimes for no fault of our own. things just don t go as planned. One way of dealing with it is to be able to laugh at ourselves. Of course. a setback itself is not to be taken lightly, but a leader capable of lightening the moment is more likely to set a positive tone for the try, try again. Staying optimistic is important for team morale. specifically when a project is dealt a huge downsizing blow. After his project was cut significantly, Tom Sutliff was able to show his team that all was not lost and to help them focus on the fact that they still had a job to do. He had to balance the new project requirements with the fact that his team had been committed to the original prcject and would be personally affected. He stood back, got a new perspective. and upheld the positivity needed to lead them effectively. Even when you keep your chin up and work to the best of your ability, things still go wrong. It's human nature. People train for years to make it to the Olympics and blow their shot during one crucial second in the spotlight. For Marty Davis, his crucial second was when the contractor dropped his 3,000 pound spacecraft. Rather than point the finger at those around him. Marty stood up like a true leader and acknowledged what he could do better if ever in this situation again.

There are no studies researching the relationship between house-poor persons and mental health. Therefore, this study aimed to investigate the relationship between house-poor status and depressive symptoms. To examine the relationship between the house-poor and depressive symptoms according to household income. Data from the Korean Welfare Panel Study were used. House-poor were defined as people having possession with over 10% house-related interest in disposable income. About 7,565 participants over the age of 19 years were followed up from 2011 to 2013. The generalized estimating equations were used for analysis. Individuals with more house-related debt showed increasingly higher depression scores (possession with under 5% related debt to disposable income β = 0.2024, p = .1544; under 10% β = 0.7030, p = .0008; over 10% β = 1.3207, p < .0001). Individuals possessing houses with over 10% ratio of house-related debts to disposable income had higher depression scores than individuals without house ownership (no possession β = 0.8927, p < .0001). Individuals without houses and individuals owning houses with higher percentages of house-related interests showed higher levels of depressive symptoms. Therefore, this study affirmed that the importance of considering the most vulnerable groups in addressing the mental health of individual. © The Author(s) 2016.

Body mass index assessment using self-reported height and weight (BMIsr) can encounter refusals and under/over-reporting while for assessment with measured data (BMIm) refusals can be more frequent. This could relate to socioeconomic and health-related factors. We explored these issues by investigating numerous potential factors: gender, age, family structure, father's occupation, income, physical/sports activity, subjective weight perception, school performance, unhealthy behaviours, physical/psychological health, social relationships, living environment, having sustained violence, sexual abuse, and involvement in violence. The sample included 1559 adolescents from middle schools in north-eastern France. They completed a questionnaire including socioeconomic and health-related data, self-reported height/weight, measured height/weight, and weight perception (participation rate 94%). Data were analysed using logistic regression models. BMIsr encountered under-reporting (with change in BMI category, 11.8%), over-reporting (6.0%), and reporting refusals (3.6%). BMIm encountered more numerous refusals (7.9%). Reporting refusal was related to living with a single parent, low school performance, lack of physical/sports activity, sustained violence, poor psychological health, and poor social relationships (gender/age-adjusted odds ratios 1.95 to 2.91). Further to these factors, measurement refusal was related to older age, having divorced/separated parents, a father being a manual worker/inactive, insufficient family income, tobacco/cannabis use, involvement in violence, poor physical health, and poor living environment (1.30 to 3.68). Under-reporting was related to male gender, involvement in violence, poor psychological health, and overweight/obesity (as assessed with BMIm) (1.52 to 11). Over-reporting was related to male gender, younger age, alcohol consumption, and underweight (1.30 to 5.35). Weight perception was linked to reporting refusals and under/over-reporting, but slightly linked to measurement refusal. The contributions of socioeconomic and health-related factors to the associations of weight perception with reporting refusal and under/over-reporting ranged from -82% to 44%. There were substantial discrepancies in the associations between socioeconomic/health-related factors and overweight/obesity assessed with BMIsr and BMIm. BMIsr and BMIm were affected by numerous biases related to vulnerability which were also obesity risk factors. BMIsr encountered under/over-reporting which were related to some socioeconomic and health-related factors, weight perception, and BMIm. BMIm was more affected by refusals than BMIsr due to socioeconomic and health-related factors. Further research is needed.

Current Perspective in the International Trade of Medicinal Plants Material: An Update.

PubMed

Vasisht, Karan; Sharma, Neetika; Karan, Maninder

2016-01-01

The recent years have seen an increased interest in medicinal plants together with the therapeutic use of phytochemicals. Medicinal plants are utilized by the industry for the production of extracts, phytopharmaceuticals, nutraceuticals and cosmeceuticals and their use is expected to grow faster than the conventional drugs. The enormous demand of medicinal plant material has resulted in huge trade both at domestic and international levels. The trade data of medicinal plant material with commodity code HS 1211 (SITC.4, code 292.4) and their derived/related products which are traded under different commodity codes has been acquired from COMTRADE, Trade Map, country reports, technical documents etc for the period 2001 to 2014. The data was analyzed using statistical tools to draw conclusions. The significant features of the global trade; the leading source, consumer, import and export countries; and the striking trends are presented. The trade of the ten key countries and the selected important items is also discussed in detail. The conservative figure of trade of medicinal plants materials and their derived/related products including extracts, essential oils, phytopharmaceuticals, gums, spices used in medicine, tannins for pharmaceutical use, ingredients for cosmetics etc. as calculated from the global export data for the year 2014 is estimated at USD 33 billion. The average global export in medicinal plants under HS 1211 for the fourteen year period was USD 1.92 billion for 601,357 tons per annum and for the year 2014 it stood at 702,813 tons valued at USD 3.60 billion. For the studied period, an annual average growth rate (AAGR) of 2.4% in volumes and 9.2% in values of export was observed. Nearly 30% of the global trade is made up by top two countries of the import and export. China and India from Asia; Egypt and Morocco from Africa; Poland, Bulgaria and Albania from Europe; Chile and Peru from South America are important supply sources. The USA, Japan and Europe are the major consumers of the world.

The relationship between poor sleep and inhibitory functions indicated by event-related potentials.

Breimhorst, Markus; Falkenstein, Michael; Marks, Anke; Griefahn, Barbara

2008-06-01

The present study focused on the relationship between normal variations of sleep and inhibitory functions as reflected in event-related potentials. For this reason one night of 21 healthy participants was analysed. After waking up all participants completed a visual Go/Nogo task. On the basis of a sleep disturbance index (SDI) the participants were separated into 8 SDI-good and 13 SDI-poor sleepers using a cluster analysis. The results showed that Nogo-N2 amplitude was smaller and Nogo-P3 latency longer in SDI-poor sleepers. Moreover, Go-P3 amplitude was smaller in SDI-poor sleepers. Performance parameters were not influenced by poor sleep. We concluded that poor sleep specifically affects the intensity of pre-motor inhibitory processes (Nogo-N2 amplitude), the speed to inhibit a motor response (Nogo-P3 latency) and the intensity of task-relevant information processing (Go-P3 amplitude). In further studies, it should be explored under which conditions such subliminal deficits also become relevant for overt behaviour.

Residents of poor nations have a greater sense of meaning in life than residents of wealthy nations.

PubMed

Oishi, Shigehiro; Diener, Ed

2014-02-01

Using Gallup World Poll data, we examined the role of societal wealth for meaning in life across 132 nations. Although life satisfaction was substantially higher in wealthy nations than in poor nations, meaning in life was higher in poor nations than in wealthy nations. In part, meaning in life was higher in poor nations because people in those nations were more religious. The mediating role of religiosity remained significant after we controlled for potential third variables, such as education, fertility rate, and individualism. As Frankl (1963) stated in Man's Search for Meaning, it appears that meaning can be attained even under objectively dire living conditions, and religiosity plays an important role in this search.

Reading Comprehension Deficits in Adolescents: Addressing Underlying Language Abilities.

PubMed

Nippold, Marilyn A

2017-04-20

The purpose of this article is to discuss reading comprehension deficits in adolescents in relation to their word reading skills and lexical and syntactic development. Although reading comprehension strategies (e.g., "Find the main idea") are often recommended, it is argued that before these can be effective, students' underlying language deficits should be addressed. Data from a longitudinal study are analyzed to determine the relationship between reading comprehension, word reading, and lexical and syntactic development in adolescents. The findings indicate that poor reading comprehension in adolescents is predicted by concurrent deficits in word reading ability, lexical development, and syntactic development. When poor comprehension is accompanied by deficits in word reading ability and/or lexical and syntactic development, intervention should target the underlying areas of deficiency. Studies designed to improve reading comprehension in adolescents are needed.

CAPE CANAVERAL, Fla. – As seen on Google Maps, the Rotating Service Structure at Launch Complex 39A at NASA's Kennedy Space Center housed space shuttle payloads temporarily so they could be loaded inside the 60-foot-long cargo bay of a shuttle before launch. The RSS, as the structure was known, was hinged to the Fixed Service Structure on one side and rolled on a rail on the other. As its name suggests, the enclosed facility would rotate into place around the shuttle as it stood at the launch pad. Once in place, the RSS protected the shuttle and its cargo. Google precisely mapped the space center and some of its historical facilities for the company's map page. The work allows Internet users to see inside buildings at Kennedy as they were used during the space shuttle era. Photo credit: Google/Wendy Wang

Examining Harry Thaw's "brain-storm" defense: APA and ANA presidents as expert witnesses in a 1907 trial.

Pinta, Emil R

2008-06-01

In 1907, Harry K. Thaw, son of a railroad multi-millionaire, stood trial for shooting and killing architect Stanford White during the performance of a Broadway musical. The defense claimed that Thaw had experienced a "brain storm" causing temporary insanity. The brain-storm defense was ridiculed by professional groups, the public and the press. However, the defense experts were all respected leaders in their fields. They included five past or future presidents of the American Psychiatric Association and American Neurological Association. With no standard terminology in 1907, the much-maligned brain-storm diagnosis was in many respects an appropriate term for a sudden, drastic and temporary defect of reasoning having a physical cause. In spite of a strict test for mental nonresponsibility, the jury did not return a murder verdict.

Current evidence on healthy eating.

Willett, Walter C; Stampfer, Meir J

2013-01-01

Large nutritional epidemiology studies, with long-term follow-up to assess major clinical end points, coupled with advances in basic science and clinical trials, have led to important improvements in our understanding of nutrition in primary prevention of chronic disease. Although much work remains, sufficient evidence has accrued to provide solid advice on healthy eating. Good data now support the benefits of diets that are rich in plant sources of fats and protein, fish, nuts, whole grains, and fruits and vegetables; that avoid partially hydrogenated fats; and that limit red meat and refined carbohydrates. The simplistic advice to reduce all fat, or all carbohydrates, has not stood the test of science; strong evidence supports the need to consider fat and carbohydrate quality and different protein sources. This article briefly summarizes major findings from recent years bearing on these issues.

Motility of vestibular hair cells in the chick.

PubMed

Ogata, Y; Sekitani, T

1993-01-01

Recent studies of the outer hair cells in cochlea have demonstrated active motilities. However, very little study has been done on the vestibular hair cells (VHCs). The present study shows the motile response of the VHCs induced by application of Ca2+/ATP promoting contraction. Reversible cell shape changes could be shown in 10 of 16 isolated type I hair cells and 9 of 15 isolated type II hair cells by applying the contraction solution. Furthermore, the sensory hair bundles in the utricular epithelium pivoted around the base and stood perpendicularly to the apical borderline of the epithelium in response to the application of the same solution. It is suggested that the contraction of the isolated VHCs may be transferred to tension which causes the sensory hair bundles to restrict their motion in normal tissue, instead of changing the cell shape.

The salience of family worldview in mourning an elderly husband and father.

The purpose of this study was to qualitatively explore family reaction to the death of the elderly husband and father in the family. We qualitatively interviewed 34 families (a family included a widow and 2 adult biological children) approximately 6-15 months after the death. In private, one-on-one in-depth interviews, we discussed how the death affected each family member as an individual and how each member perceived that the death altered the family as a unit. An individual's worldview, embedded in the smaller culture of the family and the larger culture of society, offers a template for appropriate grief reactions. Our article builds on the constructs of worldview, grief for the husband and father, and narrative at the juncture of self-evaluation, as family members reflected on where they stood in their own journey through life.

Age-related changes in human posture control: Motor coordination tests

NASA Technical Reports Server (NTRS)

Peterka, R. J.; Black, F. O.

1989-01-01

Postural responses to support surface displacements were measured in 214 normal human subjects ranging in age from 7 to 81 years. Motor tests measured leg muscle Electromyography (EMG) latencies, body sway, and the amplitude and timing of changes in center of pressure displacements in response to sudden forward and backward horizontal translations of the support surface upon which the subjects stood. There were small increases in both EMG latencies and the time to reach the peak amplitude of center of pressure responses with increasing age. The amplitude of center of pressure responses showed little change with age if the amplitude measures were normalized by a factor related to subject height. In general, postural responses to sudden translations showed minimal changes with age, and all age related trends which were identified were small relative to the variability within the population.

An application development system (ADS) is examined for remotely sensed, multispectral data at the Earth Observations Division (EOD) at Johnson Space Center. Design goals are detailed, along with design objectives that an ideal system should contain. The design objectives were arranged according to the priorities of EOD's program objectives. Four systems available to EOD were then measured against the ideal ADS as defined by the design objectives and their associated priorities. This was accomplished by rating each of the systems on each of the design objectives. Utilizing the established priorities, it was determined how each system stood up as an ADS. Recommendations were made as to possible courses of action for EOD to pursue to obtain a more efficient ADS.

Fitbit Activity Trackers Interrupt Workplace Sedentary Behavior: A New Application.

2018-05-01

This study investigated whether Fitbit devices can reduce sedentary behavior among employees in the workplace. Participants were asked to wear Fitbits during 8-hour work shifts, 5 days per week, for 8 weeks. They were instructed to stand at least once every 30 minutes throughout the workday. The goal of the study was to determine whether standing once every 30 minutes was a feasible strategy for reducing sedentary workplace behavior. On average, participants completed 36 of 40 workdays using Fitbits. The number of times participants stood during an 8-hour workday averaged 12 stands per day (maximum 16 stands per day). These results indicate that Fitbit technology is effective for recording and tracking interruptions in sitting time; however, to reduce sitting behavior, alternate approaches are required to motivate larger numbers of workers to participate.

Fiction has galvanized the public imagination around societal concerns throughout US history, on issues including slavery, worker abuse and animal cruelty. A growing body of fiction concerned with climate change, 'cli-fi', provides the opportunity for students to engage with climate science in more visceral and affective ways. The Inspiring Climate Education Excellence (ICEE) project ran a climate and energy book club from Spring 2012 through Winter 2013, in which educators, scientists and writers participated. The fictional works were intended for audiences ranging from youth through adult, with themes of dystopia, renewal, hope, oppression, and innovation. This presentation will describe the benefits, opportunities and caveats of using these works within science teaching contexts, highlight some of the works which stood out from the rest and provide an annotated bibliography of books which were included or considered.

Dynamic Visual Acuity While Walking in Normals and Labyrinthine-Deficient Patients

Hillman, Edward J.; Bloomberg, Jacob J.; McDonald, P. Vernon; Cohen, Helen S.

1996-01-01

We describe a new, objective, easily administered test of dynamic visual acuity (DVA) while walking. Ten normal subjects and five patients with histories of severe bilateral vestibular dysfunctions participated in this study. Subjects viewed a visual display of numerals of different font sizes presented on a laptop computer while they stood still and while they walked on a motorized treadmill. Treadmill speed was adapted for 4 of 5 patients. Subjects were asked to identify the numerals as they appeared on the computer screen. Test results were reasonably repeatable in normals. The percent correct responses at each font size dropped slightly while walking in normals and dropped significantly more in patients. Patients performed significantly worse than normals while standing still and while walking. This task may be useful for evaluating post-flight astronauts and vestibularly impaired patients.

A series of 3-amino-benzo[d]isoxazole-/3-aminoindazole-based compounds were designed, synthesized and pharmacologically evaluated as tyrosine kinase c-Met inhibitors. The SAR study was conducted leading to identification of nine compounds (8d, 8e, 12, 28a-d, 28h and 28i) with IC50s less than 10nM against c-Met. Compound 28a stood out as the most potent c-Met inhibitor displaying potent inhibitory effects both at enzymatic (IC50=1.8 nM) and cellular (IC50=0.18 μM on EBC-1 cells) levels. In addition, 28a had a relatively good selectivity compared to a panel of our in-house 14 RTKs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Construction industry involves the highest risk of occupational accidents and bodily injuries, which range from mild to very severe. The aim of this cross-sectional study was to identify the factors associated with accident severity rate (ASR) in the largest Iranian construction companies based on data about 500 occupational accidents recorded from 2009 to 2013. We also gathered data on safety and health risk management and training systems. Data were analysed using Pearson's chi-squared coefficient and multiple regression analysis. Median ASR (and the interquartile range) was 107.50 (57.24- 381.25). Fourteen of the 24 studied factors stood out as most affecting construction accident severity (p<0.05). These findings can be applied in the design and implementation of a comprehensive safety and health risk management system to reduce ASR.

Designed to detect early deterioration of the hospitalised child, paediatric early warning scores (PEWS) validity in the emergency department (ED) is less validated. We aimed to evaluate sensitivity and specificity of two commonly used PEWS (Brighton and COAST) in predicting hospital admission and, for the first time, significant illness. Retrospective analysis of PEWS data for paediatric ED attendances at St Mary's Hospital, London, UK, in November 2012. Patients with missing data were excluded. Diagnoses were grouped: medical and surgical. To classify diagnoses as significant, established guidelines were used and, where not available, common agreement between three acute paediatricians. 1921 patients were analysed. There were 211 admissions (11%). 1630 attendances were medical (86%) and 273 (14%) surgical. Brighton and COAST PEWS performed similarly. hospital admission: PEWS of ≥3 was specific (93%) but poorly sensitive (32%). The area under the receiver operating curve (AUC) was low at 0.690. Significant illness: for medical illness, PEWS ≥3 was highly specific (96%) but poorly sensitive (44%). The AUC was 0.754 and 0.755 for Brighton and COAST PEWS, respectively. Both scores performed poorly for predicting significant surgical illness (AUC 0.642). PEWS ≥3 performed well in predicting significant respiratory illness: sensitivity 75%, specificity 91%. Both Brighton and COAST PEWS scores performed similarly. A score of ≥3 has good specificity but poor sensitivity for predicting hospital admission and significant illness. Therefore, a high PEWS should be taken seriously but a low score is poor at ruling out the requirement for admission or serious underlying illness. PEWS was better at detecting significant medical illness compared with detecting the need for admission. PEWS performed poorly in detecting significant surgical illness. PEWS may be particularly useful in evaluating respiratory illness in a paediatric ED. Published by the BMJ Publishing Group Limited.

In this study, febantel was dissolved under increased temperature in a nonionic surfactant Lutrol L44® and subsequently mixed into an aqueous maltodextrin solution. After 8h under static conditions, coacervation or phase separation took place. (1)H NMR spectra and HPLC analysis showed that the upper phase contained mainly all febantel, while no febantel was detected in the lower phase. Fluorescent microscopy showed that maltodextrin is distributed in the lower phase. Coacervation proved to be a promising formulation technology for certain poorly water-soluble drugs, such as febantel. The coacervate phase showed an increase in in vitro dissolution kinetics, compared to Rintal® granules. These results were confirmed in an in vivo study performed on dogs. Febantel and fenbendazole showed a significant increase in plasma concentration compared to Rintal® granules. Further studies have to be performed to transform coacervates into a solid dosage form and to prove broad applicability to other poorly soluble drugs. Copyright © 2013 Elsevier B.V.

User fees, self-selection and the poor in Bangladesh.

PubMed

Thomas, S; Killingsworth, J R; Acharya, S

1998-03-01

The widespread uncontrolled introduction of user fees in any developing country is likely to have a disastrous impact on poorer patients. Furthermore, traditional targeting schemes aimed at their exemption are often expensive, difficult to administer and ineffective at reaching those in greatest need. This research study examines how user fees can raise revenue and target poorer patients, under the right market conditions, without resorting to costly targeting schemes. The authors draw their findings from case studies of cost recovery in the health and population sectors in Bangladesh. The mechanism suggested in the paper is to use self-selection. It is argued that under certain market conditions poorer patients will choose the health-care option that is appropriate to their means. They will thus identify themselves as poor without having to be selected or tested by an independent authority. This self-selection allows the relevant authorities to cross-subsidize their market choice by over-charging the non-poor in other segments of the market.

Detection of selective sweeps in structured populations: a comparison of recent methods.

PubMed

Vatsiou, Alexandra I; Bazin, Eric; Gaggiotti, Oscar E

2016-01-01

Identifying genomic regions targeted by positive selection has been a long-standing interest of evolutionary biologists. This objective was difficult to achieve until the recent emergence of next-generation sequencing, which is fostering the development of large-scale catalogues of genetic variation for increasing number of species. Several statistical methods have been recently developed to analyse these rich data sets, but there is still a poor understanding of the conditions under which these methods produce reliable results. This study aims at filling this gap by assessing the performance of genome-scan methods that consider explicitly the physical linkage among SNPs surrounding a selected variant. Our study compares the performance of seven recent methods for the detection of selective sweeps (iHS, nSL, EHHST, xp-EHH, XP-EHHST, XPCLR and hapFLK). We use an individual-based simulation approach to investigate the power and accuracy of these methods under a wide range of population models under both hard and soft sweeps. Our results indicate that XPCLR and hapFLK perform best and can detect soft sweeps under simple population structure scenarios if migration rate is low. All methods perform poorly with moderate-to-high migration rates, or with weak selection and very poorly under a hierarchical population structure. Finally, no single method is able to detect both starting and nearly completed selective sweeps. However, combining several methods (XPCLR or hapFLK with iHS or nSL) can greatly increase the power to pinpoint the selected region. © 2015 John Wiley & Sons Ltd.

Linking Family Economic Hardship to Early Childhood Health: An Investigation of Mediating Pathways.

PubMed

Hsu, Hui-Chin; Wickrama, Kandauda A S

2015-12-01

The underlying mechanisms through which family economic adversity influences child health are less understood. Taking a process-oriented approach, this study examined maternal mental health and investment in children, child health insurance, and child healthcare as mediators linking family economic hardship (FEH) to child health. A structural equation modeling was applied to test the hypothesized mediating model. After adjustment for sociodemographic risk factors, results revealed: (1) a significant direct path linking FEH to poor child health (effect size = .372), and (2) six significant mediating pathways (total effect size = .089). In two mediating pathways, exposures to FEH undermined mothers' mental health: in the first pathway poor maternal mental health led to decreased parental investment, which, in turn, contributed to poor child health, whereas in the second pathway the adverse effect of poor maternal mental health was cascaded through child unmet healthcare need, which resulted in poor child health. One pathway involved child insurance status, where the effect of FEH increased the likelihood to be uninsured, which led to unmet healthcare need, and, in turn, to poor health. Three pathways involved preventive care: in one pathway FEH contributed to poor preventive care, which led to unmet healthcare need and then to poor health; in the other two pathways where poor preventive care respectively gave rise to decreased investment in children or poor maternal mental health, which further contributed to poor child health. Results suggest that the association between FEH and children's health is mediated by multiple pathways.

Understanding the gaps in missed opportunities for vaccination (MOV) in sub-Saharan Africa would inform interventions for improving immunisation coverage to achieving universal childhood immunisation. We aimed to conduct a multicountry analyses to decompose the gap in MOV between poor and non-poor in SSA. We used cross-sectional data from 35 Demographic and Health Surveys in SSA conducted between 2007 and 2016. Descriptive statistics used to understand the gap in MOV between the urban poor and non-poor, and across the selected covariates. Out of the 35 countries included in this analysis, 19 countries showed pro-poor inequality, 5 showed pro-non-poor inequality and remaining 11 countries showed no statistically significant inequality. Among the countries with statistically significant pro-illiterate inequality, the risk difference ranged from 4.2% in DR Congo to 20.1% in Kenya. Important factors responsible for the inequality varied across countries. In Madagascar, the largest contributors to inequality in MOV were media access, number of under-five children, and maternal education. However, in Liberia media access narrowed inequality in MOV between poor and non-poor households. The findings indicate that in most SSA countries, children belonging to poor households are most likely to have MOV and that socio-economic inequality in is determined not only by health system functions, but also by factors beyond the scope of health authorities and care delivery system. The findings suggest the need for addressing social determinants of health.

Two runways were evaluated under artificially wetted conditions with the NASA diagonal-braked vehicle (DBV). Results of the evaluation which included a pavement drainage analysis, a pavement skid resistance analysis, and a DBV wet/dry stopping distance ratio analysis indicated that the ungrooved runway surfaces had poor water drainage characteristics and poor skid resistance under wet conditions at high speeds especially in rubbercoated areas of the runways. Grooving runways to a transverse 1-1/4 x 1/4 x 1/4 inch pattern greatly improved both the water drainage and pavement skid resistance capability of these asphaltic concrete surfaces.

Objectives: Patients with underlying conditions are at a higher risk of developing sepsis, a systematic response to infection, which has a high mortality rate. After the March 2011 Fukushima Daiichi nuclear power plant accident, there has been an influx of migrant decontamination workers; however, little is known about their health status. Case: A Japanese 55-year-old male decontamination worker, who had several underlying diseases, was transferred to our hospital in cardiopulmonary arrest. He had a history of diabetes mellitus and hypertension and a past history of tuberculosis. Control of underlying conditions was poor, with HbA1c of 13.8% at presentation. He was diagnosed with pneumonia-induced bacteremia and sepsis due to Klebsiella pneumoniae. Although spontaneous circulation returned in emergency room, he died a day after admission. Conclusion: The poor control of underlying diseases seen in this patient could have been influenced by his recent job transfer and engagement in decontamination work and additionally related to his socioeconomic status (SES). This case highlights the need for further research to elucidate the underlying diseases, working conditions, and SES of this population. PMID:27108638

An evaluation of supervised classifiers for indirectly detecting salt-affected areas at irrigation scheme level

NASA Astrophysics Data System (ADS)

Muller, Sybrand Jacobus; van Niekerk, Adriaan

2016-07-01

Soil salinity often leads to reduced crop yield and quality and can render soils barren. Irrigated areas are particularly at risk due to intensive cultivation and secondary salinization caused by waterlogging. Regular monitoring of salt accumulation in irrigation schemes is needed to keep its negative effects under control. The dynamic spatial and temporal characteristics of remote sensing can provide a cost-effective solution for monitoring salt accumulation at irrigation scheme level. This study evaluated a range of pan-fused SPOT-5 derived features (spectral bands, vegetation indices, image textures and image transformations) for classifying salt-affected areas in two distinctly different irrigation schemes in South Africa, namely Vaalharts and Breede River. The relationship between the input features and electro conductivity measurements were investigated using regression modelling (stepwise linear regression, partial least squares regression, curve fit regression modelling) and supervised classification (maximum likelihood, nearest neighbour, decision tree analysis, support vector machine and random forests). Classification and regression trees and random forest were used to select the most important features for differentiating salt-affected and unaffected areas. The results showed that the regression analyses produced weak models (<0.4 R squared). Better results were achieved using the supervised classifiers, but the algorithms tend to over-estimate salt-affected areas. A key finding was that none of the feature sets or classification algorithms stood out as being superior for monitoring salt accumulation at irrigation scheme level. This was attributed to the large variations in the spectral responses of different crops types at different growing stages, coupled with their individual tolerances to saline conditions.

To review literature regarding online educational initiatives in palliative care which are targeted to update health professionals and prepare distance courses suitable for a Brazilian context. 7 databases (PubMed, Cochrane Library, LILACS, SCIELO, CINAHL, Science Direct and Scopus) were reviewed for published papers between January 2004 and August 2014 using the PRISMA methodology. Included studies focused on health professionals and had at least part of the course in a distance learning approach. The UK, the USA, Canada and Australia stood out within the palliative care research papers. Among the 590 articles chosen, only 14 papers were included in this review due to the inclusion criteria. 9 used a mixed approach and 5 used online methods. The length of the courses, however, varied extensively and several methods were found to have been employed for teaching purposes, including videos, audio, images, poetry and simulation cases. Although the literature is abundant in this area, there is limited research exploring the construction process of courses and how they can be applied to countries with limited resources. It is important to highlight, however, that the mixed teaching strategy, which allows for theoretical and practical activities at a low cost, is imperative for countries with limited resources in healthcare. Thus, this review can support new initiatives around the world, particularly in the low-income and middle-income countries. Published by the BMJ Publishing Group Limited.

WOMEN’S SOCIAL BEHAVIOR WHEN MEETING NEW MEN: THE INFLUENCE OF ALCOHOL AND CHILDHOOD SEXUAL ABUSE

PubMed Central

Parks, Kathleen A.; Hequembourg, Amy L.; Dearing, Ronda L.

2008-01-01

Heavy alcohol consumption (Testa & Parks, 1996) and childhood sexual abuse (CSA; Messman-Moore & Long, 2003) have been associated with adult sexual victimization. We examined the social behavior of 42 women under two alcohol conditions (high dose and low dose) in a bar laboratory. Women were videotaped interacting with a man they had just met. Women in the higher dose condition engaged in more open body position and talked, stood, and walked more than women in the lower dose condition. These behaviors are consistent with signs of intoxication or romantic interest. The women in the high-dose condition also frowned more than women in the low-dose condition. An increase in frowning could indicate less comfort or may be considered consistent with an increase in animation during the social interaction given the concomitant increase in other behaviors. Thus, the nonverbal behavior of women in the high-dose condition could be interpreted as mixed signals. CSA victims exhibited fewer head movements (e.g., nods), were less animated, and frowned more than non-CSA victims. These behaviors convey reticence or possibly even anxiety or discomfort during the social interaction. Thus, the nonverbal behavior of women with a history of CSA may convey an unease that could be viewed by a potential perpetrator as vulnerability. Our findings suggest that both acute alcohol consumption and history of CSA may influence nonverbal social behavior and may influence risk for sexual assault by sending mixed cues of romantic interest or signs of vulnerability to potential perpetrators.

Visual motion combined with base of support width reveals variable field dependency in healthy young adults.

We previously reported responses to induced postural instability in young healthy individuals viewing visual motion with a narrow (25 degrees in both directions) and wide (90 degrees and 55 degrees in the horizontal and vertical directions) field of view (FOV) as they stood on different sized blocks. Visual motion was achieved using an immersive virtual environment that moved realistically with head motion (natural motion) and translated sinusoidally at 0.1 Hz in the fore-aft direction (augmented motion). We observed that a subset of the subjects (steppers) could not maintain continuous stance on the smallest block when the virtual environment was in motion. We completed a posteriori analyses on the postural responses of the steppers and non-steppers that may inform us about the mechanisms underlying these differences in stability. We found that when viewing augmented motion with a wide FOV, there was a greater effect on the head and whole body center of mass and ankle angle root mean square (RMS) values of the steppers than of the non-steppers. FFT analyses revealed greater power at the frequency of the visual stimulus in the steppers compared to the non-steppers. Whole body COM time lags relative to the augmented visual scene revealed that the time-delay between the scene and the COM was significantly increased in the steppers. The increased responsiveness to visual information suggests a greater visual field-dependency of the steppers and suggests that the thresholds for shifting from a reliance on visual information to somatosensory information can differ even within a healthy population.

Change of a motor synergy for dampening hand vibration depending on a task difficulty.

PubMed

Togo, Shunta; Kagawa, Takahiro; Uno, Yoji

2014-10-01

The present study investigated the relationship between the number of usable degrees of freedom (DOFs) and joint coordination during a human-dampening hand vibration task. Participants stood on a platform generating an anterior-posterior directional oscillation and held a water-filled cup. Their usable DOFs were changed under the following conditions of limb constraint: (1) no constraint; (2) ankle constrained; and (3) ankle-knee constrained. Kinematic whole-body data were recorded using a three-dimensional position measurement system. The jerk of each body part was evaluated as an index of oscillation intensity. To quantify joint coordination, an uncontrolled manifold (UCM) analysis was applied and the variance of joints related to hand jerk divided into two components: a UCM component that did not affect hand jerk and an orthogonal (ORT) component that directly affected hand jerk. The results showed that hand jerk when the task used a cup filled with water was significantly smaller than when a cup containing stones was used, regardless of limb constraint condition. Thus, participants dampened their hand vibration utilizing usable joint DOFs. According to UCM analysis, increasing the oscillation velocity and the decrease in usable DOFs by the limb constraints led to an increase of total variance of the joints and the UCM component, indicating that a synergy-dampening hand vibration was enhanced. These results show that the variance of usable joint DOFs is more fitted to the UCM subspace when the joints are varied by increasing the velocity and limb constraints and suggest that humans adopt enhanced synergies to achieve more difficult tasks.

The MS Choices Survey: findings of a study assessing physician and patient perspectives on living with and managing multiple sclerosis

Background Treatment of multiple sclerosis (MS) with disease-modifying drugs (DMDs) can reduce relapse frequency and delay disability progression. Although adherence to DMDs is difficult to measure accurately, evidence suggests that poor adherence is common and can compromise treatment success. There are likely to be multiple factors underlying poor adherence. To better understand these factors, the global MS Choices Survey investigated patient and physician perspectives regarding key aspects of MS diagnosis, treatment adherence and persistence, and disease management. Methods The survey was conducted in seven countries and involved patients with MS (age 18–60 years; MS diagnosis for ≥1 year; current treatment with a DMD) and physicians (neurologist for 3–30 years; treating ≥15 patients with MS per average month; >60% of time spent in clinical practice). Separate questionnaires were used for physicians and patients, each containing approximately 30 questions. Results Questionnaires were completed by 331 patients and 280 physicians. Several differences were observed between the responses of patients and physicians, particularly for questions relating to treatment adherence. Overall, the proportion of patients reporting taking a treatment break (31%) was almost twice that estimated by physicians (on average 17%). The reasons cited for poor adherence also differed between patients and physicians. For example, more physicians cited side effects as the main reason for poor patient adherence (82%), than responding patients (42%). Conclusions Physicians may underestimate the scale of poor adherence to DMDs, which could impact on their assessment of treatment efficacy and result in inappropriate treatment escalation. In addition, disparities were identified between patient and physician responses regarding the underlying reasons for poor adherence. Improvements in the dialog between patients and neurologists may increase adherence to DMDs. PMID:22259240

Ethnic differentials in parental health seeking for childhood illness in Vietnam.

PubMed

Teerawichitchainan, Bussarawan; Phillips, James F

2008-03-01

Vietnam's sustained investment in primary healthcare since the onset of socialism has lowered infant and childhood mortality rates and improved life expectancy, exceeding progress achieved in other poor countries with comparable levels of income per capita. The recent introduction of user fees for primary healthcare services has generated concern that economic policies may have adversely affected health-seeking behavior and health outcomes of the poor, particularly among impoverished families who are members of socially marginalized minority groups. This paper examines this debate by analyzing parental recall of illness and care-seeking for sick children under the age of 5 years recorded by the 2001-2002 Vietnam National Health Survey. We estimate statistical models of the determinants of parental recall of incidence and response to illness among their children. Ethnic minority parents less frequently reported their children to have been sick than Kinh and Chinese parents. When they recognize an illness episode, minority parents are less likely to seek care -- whether professional consultation or self-prescribed care -- than non-minority parents. Ethnic differentials are evident in all geographic and income levels, although adverse effects of minority status are most pronounced among poor households in remote areas. Regression estimates of the effects of ethnicity and maternal education on health decisions are pronounced even when poverty effects are controlled, suggesting that social equity may have been under-emphasized in Vietnam's early health policy deliberations. Policies extending free healthcare to poor communes affect parental decisions to seek professional care or self-prescribed care among better-off parents without affecting parental decision making among the poor. Early health initiatives for the poor may therefore have failed to offset equity problems confronting impoverished ethnic minority families.

Burst suppression ratio (BSR) is a quantitative electroencephalography (qEEG) parameter. The purpose of our study was to compare the accuracy of BSR when compared to other EEG parameters in predicting poor outcomes in adults who sustained post-anoxic coma while not being subjected to therapeutic hypothermia. EEG was registered and recorded at least once within 7 days of post-anoxic coma onset. Electrodes were placed according to the international 10-20 system, using a 16-channel layout. Each EEG expert scored raw EEG using a grading scale adapted from Young and scored amplitude-integrated electroencephalography tracings, in addition to obtaining qEEG parameters defined as BSR with a defined threshold. Glasgow outcome scales of 1 and 2 at 3 months, determined by two blinded neurologists, were defined as poor outcome. Sixty patients with Glasgow coma scale score of 8 or less after anoxic accident were included. The sensitivity (97.1%), specificity (73.3%), positive predictive value (82.5%), and negative prediction value (95.0%) of BSR in predicting poor outcome were higher than other EEG variables. BSR1 and BSR2 were reliable in predicting death (area under the curve > 0.8, P < 0.05), with the respective cutoff points being 39.8% and 61.6%. BSR1 was reliable in predicting poor outcome (area under the curve  =  0.820, P < 0.05) with a cutoff point of 23.9%. BSR1 was also an independent predictor of increased risk of death (odds ratio  =  1.042, 95% confidence intervals: 1.012-1.073, P  =  0.006). BSR may be a better predictor in prognosticating poor outcomes in patients with post-anoxic coma who do not undergo therapeutic hypothermia when compared to other qEEG parameters.

Ridge Regression Signal Processing

Kuhl, Mark R.

1990-01-01

The introduction of the Global Positioning System (GPS) into the National Airspace System (NAS) necessitates the development of Receiver Autonomous Integrity Monitoring (RAIM) techniques. In order to guarantee a certain level of integrity, a thorough understanding of modern estimation techniques applied to navigational problems is required. The extended Kalman filter (EKF) is derived and analyzed under poor geometry conditions. It was found that the performance of the EKF is difficult to predict, since the EKF is designed for a Gaussian environment. A novel approach is implemented which incorporates ridge regression to explain the behavior of an EKF in the presence of dynamics under poor geometry conditions. The basic principles of ridge regression theory are presented, followed by the derivation of a linearized recursive ridge estimator. Computer simulations are performed to confirm the underlying theory and to provide a comparative analysis of the EKF and the recursive ridge estimator.

Although there has been extensive research on the adverse impacts of perceived discrimination on health, it remains unclear how perceived discrimination gets under the skin. This paper develops a comprehensive structural equation model (SEM) by incorporating both the direct effects of perceived discrimination on self-rated health (SRH), a powerful predictor for many health outcomes, and the indirect effects of perceived discrimination on SRH through health care system distrust, neighborhood social capital, and health behaviors and health conditions. Applying SEM to 9,880 adults (aged between 18 and 100) in the 2008 Southeastern Pennsylvania Household Health Survey, we not only confirmed the positive and direct association between discrimination and poor or fair SRH, but also verified two underlying mechanisms: 1) perceived discrimination is associated with lower neighborhood social capital, which further contributes to poor or fair SRH; and 2) perceived discrimination is related to risky behaviors (e.g., reduced physical activity and sleep quality, and intensified smoking) that lead to worse health conditions, and then result in poor or fair SRH. Moreover, we found that perceived discrimination is negatively associated with health care system distrust, but did not find a significant relationship between distrust and poor or fair SRH.

Stress and salicylic acid induce the expression of PnFT2 in the regulation of the stress-induced flowering of Pharbitis nil.

PubMed

Yamada, Mizuki; Takeno, Kiyotoshi

2014-02-15

Poor nutrition and low temperature stress treatments induced flowering in the Japanese morning glory Pharbitis nil (synonym Ipomoea nil) cv. Violet. The expression of PnFT2, one of two homologs of the floral pathway integrator gene FLOWERING LOCUS T (FT), was induced by stress, whereas the expression of both PnFT1 and PnFT2 was induced by a short-day treatment. There was no positive correlation between the flowering response and the homolog expression of another floral pathway integrator gene SUPPRESSOR OF OVEREXPRESSION OF CO1 and genes upstream of PnFT, such as CONSTANS. In another cultivar, Tendan, flowering and PnFT2 expression were not induced by poor nutrition stress. Aminooxyacetic acid (AOA), a phenylalanine ammonia-lyase inhibitor, inhibited the flowering and PnFT2 expression induced by poor nutrition stress in Violet. Salicylic acid (SA) eliminated the inhibitory effects of AOA. SA enhanced PnFT2 expression under the poor nutrition stress but not under non-stress conditions. These results suggest that SA induces PnFT2 expression, which in turn induces flowering; SA on its own, however, may not be sufficient for induction. Copyright © 2013 Elsevier GmbH.

Belonging and community: understandings of "home" and "friends" among the English poor, 1750-1850.

PubMed

Snell, K D M

2012-01-01

This article is based on unique ‘narratives of the poor’, that is, letters from poor people to their parishes of settlement, petitions to the London Refuge of the Destitute, and letters from mothers to the London Foundling Hospital, with supportive evidence from newspapers. These display fundamental concepts among the English poor, who were often poorly literate, and who comprised the majority of the population. Discussion focuses upon their understandings of ‘home’, ‘belonging’, ‘friends’, and ‘community’. These key concepts are related here to modern discussions, to set important concerns into historical perspective. ‘Friends’, valuably studied by sociologists such as Pahl, had a wide meaning in the past. ‘Home’ meant (alongside abode) one's parish of legal settlement, where one was entitled to poor relief under the settlement/poor laws. This was where one ‘belonged’. Ideas of ‘community’ were held and displayed even at a distance, among frequently migrant poor, who wrote to their parishes showing strong ties of attachment, right, and local obligation. This discussion explores these issues in connection with belonging and identity. It elucidates the meaning and working of poor law settlement, and is also an exploration of popular mentalities and the semi-literate ways in which these were expressed.

While parent-adolescent sexual and reproductive health (SRH) communication is one potential source of SRH information for adolescents, it appears to be inadequately practiced in Ethiopia. This study was designed to investigate the factors that limit or improve parent-adolescent SRH communication in Harar, Eastern Ethiopia. A community based cross-sectional study was done on 4,559 adolescents of age 13-18. SRH communication was measured using a nine-item scale whose response ranged from "not at all" to "always." Summated composite score ranging from 0-36 was generated; higher score indicates high SRH communication. A median value of the composite score was 4 out of the possible 36 with an Interquartile Range (IQR) of 7. Respondents were ranked as very poor, poor and satisfactory communicators based on 33rd and 67th percentiles values. Generalized ordered logit model was applied to investigate the factors associated with SRH communication. Results showed that the adolescents who were more likely to practice poor-very poor/very poor SRH communication were those who had poor behavioral beliefs on and poor subjective norms of communicating sexual issues with parents and those who perceived their parents' reproductive health (RH) knowledge as poor. Nonetheless, the probability of poor-very poor/very poor SRH communication was less with high adolescent-parent communication quality, television co-viewing and discussions, and self-disclosure. Curtailing the adolescents' underlying poor beliefs and norms, and improving adolescent-parent communication quality, self-disclosure, and television co-viewing and discussions are essential to engage the parents in sexual and reproductive health education of the adolescents.

Pancreatic neuroendocrine tumors (PanNETs) are a relatively rare but clinically challenging tumor type. In particular, high grade, poorly-differentiated PanNETs have the worst patient prognosis, and the underlying mechanisms of disease are poorly understood. In this study we have identified and characterized a previously undescribed class of poorly differentiated PanNETs in the RIP1-Tag2 mouse model. We found that while the majority of tumors in the RIP1-Tag2 model are well-differentiated insulinomas, a subset of tumors had lost multiple markers of beta-cell differentiation and were highly invasive, leading us to term them poorly differentiated invasive carcinomas (PDICs). In addition, we found that these tumors exhibited a high mitotic index, resembling poorly differentiated (PD)-PanNETs in human patients. Interestingly, we identified expression of Id1, an inhibitor of DNA binding gene, and a regulator of differentiation, specifically in PDIC tumor cells by histological analysis. The identification of PDICs in this mouse model provides a unique opportunity to study the pathology and molecular characteristics of PD-PanNETs.

Poor comprehenders are children who show significant deficits in their reading comprehension performance, despite average, or above-average word reading ability. To date, there have been no in-depth studies of the mathematical performance profiles of such children. This study aimed to explore the mathematical profiles of poor comprehenders. Given that language impairment is associated with difficulties with mathematics, and that poor comprehenders tend to have oral language weaknesses, we hypothesized that poor comprehenders would show relative weaknesses in aspects of mathematical performance. From a sample of 109 children aged 7-8 years, we selected 14 poor comprehenders and 14 controls with age-appropriate reading comprehension ability. The groups were matched on non-verbal ability, multiple measures of reading accuracy, and chronological age. We compared the performance of the group of poor comprehenders with that of the matched controls on two standardized measures of mathematical ability, one measuring procedural arithmetic prowess and the other tapping higher-level mathematical reasoning. Although there were no group differences in performance on the arithmetic measure, the poor comprehenders showed significantly lower scores than the controls on the mathematical reasoning task. The poor comprehenders exhibited impaired verbal ability relative to controls, with these differences in verbal ability associated with the group differences found on the test of mathematical reasoning. Poor comprehenders' deficits are not limited to the domain of literacy; their underlying profile of impairments also seems to selectively impact on certain components of mathematical ability.

This community based cross-sectional study examined the prevalence and factors associated with depression among urban poor in Peninsular Malaysia. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depression. The prevalence of depression among the urban poor was 12.3%. Factors significantly associated with depression included respondents under 25 years old, male gender, living in the area for less than four years and those who do not exercise regularly. It is important to identify individuals with depression and its associated factors early because depression can severely affect the quality of life.

To determine prenatal and postnatal independent predictors of poor outcome, spontaneous resolution, or the need for surgery in patients with prenatal hydronephrosis. We performed a retrospective study of patients with prenatal hydronephrosis. The renal pelvis APD was measured in the third prenatal trimester ultrasound, as well as in the first and second postnatal ultrasound. Other variables were taken into account, both prenatal and postnatal. For statistical analysis we used Student t-test, chi-square test, survival analysis, logrank test, and ROC curves. We included 218 patients with 293 renal units (RU). Of these, 147/293 (50.2%) RU were operated. 76/293 (25.9%) RU had spontaneous resolution and other 76/293 (25.9%) RU had poor outcome. As risk factors for surgery we found low birth weight (OR 3.84; 95% CI 1.24-11.84), prematurity (OR 4.17; 95% CI 1.35-12.88), duplication (OR 4.99; 95% CI 2.21-11.23) and the presence of nephrourological underlying pathology (OR 53.54; 95% CI 26.23-109.27). For the non-spontaneous resolution, we found as risk factors the alterations of amniotic fluid volume (RR 1.46; 95% CI 1.33-1.60) as well as the underlying nephrourological pathology and duplication. In the poor outcome, we found as risk factors the alterations of amniotic fluid volume (OR 4.54; 95% CI 1.31-15.62), the presence of nephrourological pathology (OR 4.81 95% CI 2.60-8.89) and RU that was operated (OR 4.23, 95% CI 2.35-7.60). The APD of the renal pelvis in all three ultrasounds were reliable for surgery prediction (area under the curve 0.65; 0.82; 0.71) or spontaneous resolution (area under the curve 0.80; 0.91; 0.80), only the first postnatal ultrasound has predictive value in the poor outcome (area under the curve 0.73). The higher sensitivity and specificity of the APD as predictor value was on the first postnatal ultrasound, 14.60 mm for surgery; 11.35 mm for spontaneous resolution and 15.50 mm for poor outcome. The higher APD in the renal pelvis in any of the three ultrasounds, the greater the chances of surgery and failure of spontaneous resolution. The first postnatal ultrasound is the most reliable in predicting outcome of prenatal hydronephrosis. There are other factors to take into account to predict the outcomes of these patients.

Plunging into the pool of death: Imagining a dangerous outcome influences distance perception

The current studies examined whether manipulating the imagined consequences of falling would influence the perception of height, distance, and size. In Experiment 1, height and size perception were measured when participants stood at a short height (.89 m) or a medium height (1.91 m) above either an empty pool or a pool filled with a bed of nails. Participants who viewed the bed of nails and imagined falling into it estimated both the height as taller and the size of the bed of nails as larger than participants who imagined falling into an empty pool. In a second experiment, participants overestimated the horizontal ground distance to and across the bed of nails after being told to imagine jumping over it. Overall, these experiments suggest that costs associated with imagined actions can influence the perception of both vertical and horizontal extents that are not inherently dangerous. PMID:22611659

Nurses without borders: the history of nursing as U.S. international history.

Irwin, Julia F

2011-01-01

During World War I and its aftermath, thousands of U.S. nurses put their domestic careers on hold to work overseas. Many volunteered in the wake of war and disaster. Others worked as instructors in nursing schools and as the staff of fledgling public health agencies. This article charts the international travels of four especially mobile nurses, whose globetrotting careers took them to Europe, Asia, and the Caribbean. These women aspired to tackle world health issues, motivated by the conviction that the spread of U.S. professional nursing ideas stood to modernize the world. This article tells these nurses' stories and analyzes their ideologies of development and progress. In so doing, it demonstrates that professional women, working outside state channels, played a principal role in expanding U.S. influence in the world. Moreover, it makes the case for the centrality of nursing history to the history of U.S. foreign relations.

Unlike anticonvulsant drugs and vagus nerve stimulation, there are no guidelines regarding adjustments to ketogenic diet regimens to improve seizure efficacy once the diet has been started. A retrospective chart review was performed of 200 consecutive patients treated with the ketogenic diet at Johns Hopkins Hospital from 2007-2013. Ten dietary and supplement changes were identified, along with anticonvulsant adjustments. A total of 391 distinct interventions occurred, of which 265 were made specifically to improve seizure control. Adjustments lead to >50% further seizure reduction in-18%, but only 3% became seizure-free. The benefits of interventions did not decrease over time. There was a trend towards medication adjustments being more successful than dietary modifications (24% vs. 15%, p = 0.08). No single dietary change stood out as the most effective, but calorie changes were largely unhelpful (10% with additional benefit). PMID:24859788

Convergence and conflict: anthropology, psychiatry and feminism in the early writings of Madeleine Pelletier (1874-1939).

PubMed

Gordon, Felicia

2008-06-01

This paper reviews the early career and psychiatric writings of Madeleine Pelletier (1874-1939), between 1901 and 1906. Pelletier, a committed feminist and socialist, was the first woman to remove the barriers to women entering the French psychiatric profession, successfully passing the examination for the l'internat des hôpitaux psychiatriques in 1903. Her involvement in La Société d'Anthropologie de Paris and the Institut Général de Psychologie provided a forum for her interest in psychology, both normal and abnormal. She turned increasingly to sociological explanations for mental illness, unwilling to accept the determinism inherent in degeneration theory. Although her career in psychiatry was cut short in 1906, her training and her debating skills, honed in the rationalism of the scientific and Free Masonic societies that she frequented, stood her in good stead in her subsequent career as a political militant.

Classical 1D X-ray Free Electron Laser (X-ray FEL) theory has stood the test of time by guiding FEL design and development prior to any full-scale analysis. Future X-ray FELs and inverse-Compton sources, where photon recoil approaches an electron energy spread value, push the classical theory to its limits of applicability. After substantial efforts by the community to find what those limits are, there is no universally agreed upon quantum approach to design and development of future X-ray sources. We offer a new approach to formulate the quantum theory for 1D X-ray FELs that has an obvious connection to the classicalmore » theory, which allows for immediate transfer of knowledge between the two regimes. In conclusion, we exploit this connection in order to draw quantum mechanical conclusions about the quantum nature of electrons and generated radiation in terms of FEL variables.« less

Effect of antigravity suit inflation on cardiovascular, PRA, and PVP responses in humans. [Plasma Renin Activity and Plasma VasoPressin

The effects of lower body and abdominal pressure, produced by antigravity suit inflation, on blood pressure, pulse rate, fluid and electrolyte shift, plasma vasopressin and plasma renin activity in humans in upright postures were studied. Five men and two women stood upright for 3 hr with the suit being either inflated or uninflated. In the control tests, the suit was inflated only during the latter part of the trials. Monitoring was carried out with a sphygnomanometer, with sensors for pulse rates, and using a photometer and osmometer to measure blood serum characteristics. The tests confirmed earlier findings that the anti-g suit eliminates increases in plasma renin activity. Also, the headward redistribution of blood obtained in the tests commends the anti-g suit as an alternative to water immersion or bed rest for initial weightlessness studies.

The Haskell norm

NASA Astrophysics Data System (ADS)

Advocate, Dev L.

The matter of the viscosity of the mantle has started to become serious. In 1935, Norm Haskell estimated the viscosity to be about 1020 poise and there the matter stood for about half a century. For a little while, people worried about excess ellipticity of the Earth and attributed this to a “fossil bulge” that lagged the rotation rate. For this same little while, 1025 poise was thought to be the viscosity of the lower mantle, but then it was discovered that the equator was also out of shape by about the same amount, ruling out the “fossil bulge” idea. To cover their embarrassment, geodynamicists upped the viscosity of the mantle to 1021 by adopting S.I. (Satan's Invention) units. No one noticed for some time since it didn't really matter whether viscosity was given in stokes, poise, or pascal seconds. It was just a large number with a large uncertainty and no one had a feel for it anyway.

Mechanisms of racial inequalities in prevalence of diarrhoea in South Africa.

PubMed

Choi, Susanne Y P

2003-09-01

Decades of apartheid policies have resulted in marked racial inequalities in health in South Africa. The black:white rate ratio of diarrhoea among children aged less than five years, one of the five most common causes of infant and child deaths, stood at 6.5 in 1998. Using data from the 1998 South African Demographic and Health Survey, this paper examines the mechanisms of this racial disparity. The research confirms the presence of persistent racial inequalities in access to safe drinking-water and sanitation and in maternal education and household wealth, with the black population constituting the most disadvantaged group. While the living environment and access to safe drinking-water explain the excessive risk of diarrhoea among the black population compared to the coloured and Indian populations, the excessive risk of diarrhoea among the black population compared to the white population cannot be explained by disparities in the living environment, hygiene levels, and socioeconomic factors.

1977-01-01

Fifty strains of herpes simplex virus, isolated from patients with herpetic keratitis, were examined in vitro for susceptibility to polyinosinic acid-polycytidylic acid [poly(I:C)] in the presence of a constant concentration of diethylaminoethyl-dextran. The minimal inhibitory concentration of poly(I:C) for 44 of these strains ranged from 0.0001 to 0.1 μg/ml; for the remaining six strains, the minimal inhibitory concentration stood at 1 to 2 μg/ml. Fifteen isolates from primary infections were more susceptible to poly(I:C) than 35 isolates from recurrent infections. Isolates acquired at different points of a given clinical episode showed similar susceptibilities to poly(I:C). In two patients, isolates from consecutive recurrences of infection exhibited reduced susceptibilities. The implications of the above observations for the therapeutic use of poly(I:C) are discussed.

Previous descriptive surveys in the town of Cabar, Croatia carried out by our own epidemiological research group, have established that this area is at high risk for MS. To confirm the above assumption and to update MS frequency in this area we conducted a community-based intensive prevalence and incidence study. On December 31st 2001, the average prevalence was 205.7 per 100,000 with prevailing age-specific prevalence in the group of patients between 30 and 49 years of age. The average incidence (1948-2004) was 5.52/100.000 population per year (95% CI = 3.27-8.72), average mortality in the year was 2.76/100 000 inhabitants (95% CI = 1.26-5.24). Sexual index stood at 1:11, starting time was 10:04 +/- 28.53 in the year, and the average duration of the disease to the prevalence 11:11 +/- 27.26 years.

[Purpose] The present study was conducted to investigate whether ankle proprioceptive exercise affects static and dynamic balance in normal adults. [Subjects and Methods] Twenty-eight normal adults were recruited to measure their static and dynamic balancing before and after the proprioceptive exercise. A subject stood with bare feet on the round supporting platform of the device for measuring balance, and the investigator entered the age and the height of the subjects and set his/her feet on the central point of the monitor screen. Training of ankle proprioceptive sense for the movements of plantar-flexion and dorsiflexion was performed. In the training of joint position sense in plantar-flexion and dorsiflexion, the plantar-flexion and the dorsiflexion were set as 15°, respectively. [Results] The static balancing did not show significant differences in average, while the dynamic balancing showed significant differences. [Conclusion] Ankle proprioceptive exercise can affect dynamic balance.

Cultural competence, evidence-based medicine, and evidence-based practices.

PubMed

Whitley, Rob

2007-12-01

Cultural competence and evidence-based medicine are two powerful discourses that have become core components of contemporary psychiatry. Evidence-based medicine has particularly influenced psychiatry by spawning the enthusiastic creation and adoption of evidence-based practices. Despite their prominence, these paradigms have stood somewhat in isolation from each other. This Open Forum explores the relationship between these two conceptual paradigms, paying particular attention to implications for evidence-based practices. The author aims to stimulate a greater degree of mutual engagement and integration of these paradigms by examining epistemological, philosophical, and methodological overlap and discrepancy. Both paradigms can stretch and enrich each other in a positive manner. This could help achieve a situation where cultural competency becomes more evidence based and evidence-based medicine becomes more culturally competent. Such action would help bring to fruition a shared aim of both discourses-more humane, just, and effective patient-centered care.

The results show significant differences among the researchers' opinions with respect to their perceptions about science communication, the ways they participate in PUS activities and their identified needs. In general, the researchers of Conacyt perceived public communication as very important. However, lack of time and of academic recognition stood out as determining factors in their low contribution to science popularization. We conclude that, to achieve a culture of Public Engagement in public communication of science and technology among R&D institutions, the Mexican Administration should address the above-mentioned unfavorable professional circumstances.

The German dermatologist, Josef Jadassohn (1863-1936), first presented the results of his innovative patch-testing technique in 1895. The safety and efficacy of this diagnostic tool has stood the test of time and is still the gold standard for the diagnosis of allergic contact dermatitis (ACD). Since its discovery, much effort has been put into standardization and optimization of allergens, vehicles, and concentrations of patch-test materials; in procedures of its application; and in reading and scoring of test reactions--all contributing to the development of an accurate, reliable, and safe test with a high reproducibility of its results. Even this seemingly carved-in-stone practice, which has been used for nearly 120 years, has been questioned and challenged, engendering debates, disagreements, and controversies, which show no signs of coming to an end. Almost every step of the procedure has provoked discussions and controversies: Copyright © 2013 Elsevier Inc. All rights reserved.

Policy Shocks: On the Legal Auspices of Latin American Migration to the United States

PubMed Central

Riosmena, Fernando

2011-01-01

In this paper, I compare the transition into legal permanent residence (LPR) of Mexicans, Dominicans, and Nicaraguans. Dominicans had the highest likelihood of obtaining residence, mostly sponsored by parents and spouses. Mexicans had the lowest LPR transition rates and presented sharp gender differentials in modes: women mostly legalized through husbands while men were sponsored through IRCA, parents. Nicaraguans stood in-between, presenting few gender differences in rates and modes of transition and a heavy dependence on asylum and special provisions such as IRCA and NACARA. I argue these patterns stem from the interplay of conditions favoring the emigration of and the specific immigration policy context faced by migrant pioneers; the influence of social networks in reproducing the legal character of flows; and differences in the actual use of kinship ties as sponsors. I discuss the implications of these trends on the observed gendered patterns of migration from Latin America. PMID:21921965

Aqua ligands can undergo rapid internal rotation about the M-O bond. For magnetic resonance contrast agents, this rotation results in diminished relaxivity. Herein, we show that an intramolecular hydrogen bond to the aqua ligand can reduce this internal rotation and increase relaxivity. Molecular modeling was used to design a series of four Gd complexes capable of forming an intramolecular H-bond to the coordinated water ligand, and these complexes had anomalously high relaxivities compared to similar complexes lacking a H-bond acceptor. Molecular dynamics simulations supported the formation of a stable intramolecular H-bond, while alternative hypotheses that could explain the higher relaxivitymore » were systematically ruled out. Finally, intramolecular H-bonding represents a useful strategy to limit internal water rotational motion and increase relaxivity of Gd complexes.« less

Malta's population stood at 330,000 in 1983, with an annual growth rate of 0.5%. The infant mortality rate is 13.4/1000, and life expectancy is 73 years. 11 years of education is compulsory and the school attendance rate is 96%; the literacy rate is 90%. Malta's work force of 121,025 is distributed as follows: agriculture and fisheries, 4.5%; industry and commerce, 34.9%; services, 30.2%; and government, 22.3%. The gross national product (GNP) was estimated at US$1.04 billion in 1983 (per capita GNP, US$3162), with an annual growth rate of 3.5%. Malta lacks natural resources and a solid agricultural base, so tourism and trade are important. The government has taken steps to launch new export industries and build a more self-reliant economy. A goal is to attract export-oriented foreign direct investment that will provide needed technology and skills.

Since plasma for direct therapeutic use comprises no cellular fraction, it has long stood for a standardized and rather simple component; meanwhile, rules for its issuing to patients have long been strict. During the very last years, there has been a paradigm shift as novel indications have raised and possible needs for distinct types of plasma depending on the missing clotting factors in the patient. During the same period of time, plasma inactivated by solvent-detergent, which was a labile component in France, has been re-qualified by European authorities as a plasma derived-drug. The French recommendations for use of plasma - though quite recently revised (2012) - are disputed by some experts and would merit a revisit. This state-of-the art manuscript aims at presenting the novel situation of therapeutic plasma and suggesting possible evolution. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

to describe the epidemiological characteristics of cases of violence against women reported in the Federal District, Brazil, 2009-2012. this was a descriptive study of cases of violence against women aged 18- 59 registered on the National Notifiable Diseases System (Sinan). 1,924 cases of violence against women were registered, the perpetrators of which were identified as unknown (25.7%) or spouses (19.0%) of the victims; violence mainly occurred against women of brown skin color (25.0%) and in the domestic environment (38.5%); regarding violence type, physical violence (46.8%) by force (48.0%) stood out, whereby the genitals (15.7%) and the head (12.9%) were the most affected regions. physical violence in domestic environments by unknown aggressors was the main type of violence among the reported cases; shortcomings were identified in recording reported cases, showing the need to improve system quality and train health workers involved.

Space Weather Research in the Equatorial Region: A Philosophical Reinforcement

NASA Astrophysics Data System (ADS)

Chukwuma, Victor; Odunaike, Rasaki; Laoye, John

Investigations using radio waves reflected from the ionosphere, at high-and mid-latitudes indicate that ionospheric absorption can strongly increase following geomagnetic storms; which appears to suggest some definite relationship between ionospheric radio wave absorption and geomagnetic storms at these latitudes. However, corresponding earlier studies in the equatorial region did not appear to show any explicit relationship between ionospheric radio wave absorption and geomagnetic storm activity. This position appeared acceptable to the existing scientific paradigm, until in an act of paradigm shift, by a change of storm selection criteria, some more recent space weather investigations in the low latitudes showed that ionospheric radio wave absorption in the equatorial region clearly increases after intense storms. Given that these results in the equatorial region stood against the earlier results, this paper presently attempts to highlight their philosophical underpinning and posit that they constitute a scientific statement.

Thirty-eight yeast strains belonging to the genera Candida, Hanseniaspora, Pichia, Torulaspora and Zygosaccharomyces were screened for ester formation on synthetic microbiological medium. The genera Hanseniaspora and Pichia stood out as the best acetate ester producers. Based on the ester profile Hanseniaspora guilliermondii 11027 and 11102, Hanseniaspora osmophila 1471 and Pichia membranifaciens 10113 and 10550 were selected for further characterization of enological traits. When growing on must H. osmophila 1471, which displayed a glucophilic nature and was able to consume more than 90% of initial must sugars, produced levels of acetic acid, medium chain fatty acids and ethyl acetate, within the ranges described for wine. On the other hand, it was found to be a strong producer of 2-phenylethyl acetate. Our data suggest that H. osmophila 1471 is a good candidate for mixed starters, although the possible interactions with S. cerevisiae deserve further research.

Objective: The purpose of this study was to qualitatively explore family reaction to the death of the elderly husband and father in the family. Methods: We qualitatively interviewed 34 families (a family included a widow and 2 adult biological children) approximately 6–15 months after the death. In private, one-on-one in-depth interviews, we discussed how the death affected each family member as an individual and how each member perceived that the death altered the family as a unit. Results: An individual's worldview, embedded in the smaller culture of the family and the larger culture of society, offers a template for appropriate grief reactions. Discussion: Our article builds on the constructs of worldview, grief for the husband and father, and narrative at the juncture of self-evaluation, as family members reflected on where they stood in their own journey through life.

Classical 1D X-ray Free Electron Laser (X-ray FEL) theory has stood the test of time by guiding FEL design and development prior to any full-scale analysis. Future X-ray FELs and inverse-Compton sources, where photon recoil approaches an electron energy spread value, push the classical theory to its limits of applicability. After substantial efforts by the community to find what those limits are, there is no universally agreed upon quantum approach to design and development of future X-ray sources. We offer a new approach to formulate the quantum theory for 1D X-ray FELs that has an obvious connection to the classicalmore » theory, which allows for immediate transfer of knowledge between the two regimes. In conclusion, we exploit this connection in order to draw quantum mechanical conclusions about the quantum nature of electrons and generated radiation in terms of FEL variables.« less

This qualitative study is based on institutional analysis as the methodological theoretical reference with the objective of analyzing researchers' implication during a research-intervention and the interferences caused by this analysis. The study involved researchers from courses in medicine, nursing, and dentistry at two universities and workers from a Regional Health Department in follow-up on the implementation of the Stork Network in São Paulo State, Brazil. The researchers worked together in the intervention and in analysis workshops, supported by an external institutional analysis. Two institutions stood out in the analysis: the research, established mainly with characteristics of neutrality, and management, with Taylorist characteristics. Differences between researchers and difficulties in identifying actions proper to network management and research were some of the interferences that were identified. The study concludes that implication analysis is a powerful tool for such studies.

For decades, numerous attempts have been made to produce polar oxynitride perovskites, where some of the oxygen is replaced by nitrogen, but a polar ordered oxynitride has never been demonstrated. Caracas and Cohen [Appl. Phys. Lett. 91, 092902 (2007), 10.1063/1.2776370] studied possible ordered polar oxynitrides within density-functional theory (DFT) and found a few candidates that were predicted to be insulating and at least metastable. YSi O2N stood out with huge predicted polarization and nonlinear optic coefficients. In this study, we demonstrate the synthesis of perovskite-structured YSi O2N by using a combination of a diamond-anvil cell and in situ laser-heating techniques. Subsequent in situ x-ray diffraction, second-harmonic generation, and Raman-scattering measurements confirm that it is polar and a strong nonlinear optical material, with structure and properties similar to those predicted by DFT.

Opuntia spp. flowers have been traditionally used for medical purposes, mostly because of their diversity in bioactive molecules with health promoting properties. The proximate, mineral and volatile compound profiles, together with the cytotoxic and antimicrobial properties were characterized in O. microdasys flowers at different maturity stages, revealing several statistically significant differences. O. microdasys stood out mainly for its high contents of dietary fiber, potassium and camphor, and its high activities against HCT15 cells, Staphylococcus aureus, Aspergillus versicolor and Penicillium funiculosum. The vegetative stage showed the highest cytotoxic and antifungal activities, whilst the full flowering stage was particularly active against bacterial species. The complete dataset has been classified by principal component analysis, achieving clearly identifiable groups for each flowering stage, elucidating also the most distinctive features, and comprehensively profiling each of the assayed stages. The results might be useful to define the best flowering stage considering practical application purposes.

India's "tryst" with universal health coverage: reflections on ethnography in Indian health policymaking.

In 2011, India stood at the crossroads of potentially major health reform. A High Level Expert Group (HLEG) on universal health coverage (UHC), convened by the Indian Planning Commission, proposed major changes in the structure and functioning of the country's health system. This paper presents reflections on the role of ethnography in policy-based social change for health in India, drawing from year-long participation in the aforementioned policy development process. It theorizes that international discourses have been (re)appropriated in the Indian case by recourse to both experience and evidence, resulting in a plurality of concepts that could be prioritized for Indian health reform. This articulation involved HLEG members exerting para-ethnographic labour and paying close attention to context, suggesting that ethnographic sensibilities can reside within the interactive and knowledge production practices among experts oriented toward policy change.

How human beings integrate information from external sources and internal cognition to produce a coherent experience is still not well understood. During the past decades, anatomical, neurophysiological and neuroimaging research in multimodal integration have stood out in the effort to understand the perceptual binding properties of the brain. Areas in the human lateral occipito-temporal, prefrontal and posterior parietal cortices have been associated with sensory multimodal processing. Even though this, rather patchy, organization of brain regions gives us a glimpse of the perceptual convergence, the articulation of the flow of information from modality-related to the more parallel cognitive processing systems remains elusive. Using a method called Stepwise Functional Connectivity analysis, the present study analyzes the functional connectome and transitions from primary sensory cortices to higher-order brain systems. We identify the large-scale multimodal integration network and essential connectivity axes for perceptual integration in the human brain. PMID:22855814

The aims of the study were to investigate healthy subjects' performance on a clinical test of high-level language (HLL) and how it is related to demographic characteristics and verbal working memory (VWM). One hundred healthy subjects (20-79 years old) were assessed with the Swedish BeSS test (Laakso, Brunnegård, Hartelius, & Ahlsén, 2000) and two digit span tasks. Relationships between the demographic variables, VWM and BeSS were investigated both with bivariate correlations and multiple regression analysis. The results present the norms for BeSS. The correlations and multiple regression analysis show that demographic variables had limited influence on test performance. Measures of VWM were moderately related to total BeSS score and weakly to moderately correlated with five of the seven subtests. To conclude, education has an influence on the test as a whole but measures of VWM stood out as the most robust predictor of HLL.

Cardiac pacing through cardiac pacemaker is one of the most promising alternatives in the treatment of arrhythmias, but it can cause reactions natural or complex reactions, either early or late. This study aimed to describe the scientific evidence on the risk of infection and biofilm formation associated with cardiac pacemaker. This is a study of integrative literature review. It included 14 publications classified into three thematic categories: diagnosis (microbiological and/or clinical), complications and therapy of infections. Staphylococcus epidermidis and Staphylococcus aureus were the microorganisms most frequently isolated. It was not possible to determine the incidence of infection associated with pacemakers, since the studies were generally of prevalence. In terms of therapy, the complete removal of pacemakers stood out, especially in cases of suspected biofilm. Still controversial is the use of systemic antibiotic prophylaxis in reducing the incidence of infection associated with implantation of a pacemaker.

Tracking the Aftermath of Irma in Antigua and Barbuda

The twin island nation of Antigua and Barbuda were the first places heavily impacted by Hurricane Irma. The powerful imagery generated of destruction and abandonment, stood as warning for many in the U.S. Virgin Islands, Puerto Rico, and the coastal United States. This paper presents findings on how resilience in the aftermath of Irma's destruction has functioned to constitute those who are sustainable from those who are not. The two sister islands experienced completely different outcomes from Hurricane Irma, with Antigua being relatively `untouched' and Barbuda with approximately 90% of the island of the destroyed, presenting a contradictory identity of the twin-island nation both as a victim of climate change and a land of economic opportunity, "open for business". This contradiction will be unpacked through analysis of language from formal practitioner interviews, informal unstructured discussions, local climate-risk reduction policies, local newspapers, and social media.
