Full potential LAPW calculation of electron momentum density and related properties of Li

Electron momentum density and Compton profiles in Lithium along $$,$$, and $$ directions are calculated using Full-Potential Linear Augmented Plane Wave basis within generalized gradient approximation. The profiles have been corrected for correlations with Lam-Platzman formulation using self-consistent charge density. The first and second derivatives of Compton profiles are studied to investigate the Fermi surface breaks. Decent agreement is observed between recent experimental and our calculated values. Our values for the derivatives are found to be in better agreement with experiments than earlier theoretical results. Two-photon momentum density and one- and two-dimensional angular correlation of positron annihilation radiation are also calculated within the same formalism and including the electron-positron enhancement factor.Comment: 11 pages, 7 figures TO appear in Physical Review

Molecular Interpretation of ACTH-β-Endorphin Coaggregation: Relevance to Secretory Granule Biogenesis

Peptide/protein hormones could be stored as non-toxic amyloid-like structures in pituitary secretory granules. ACTH and β-endorphin are two of the important peptide hormones that get co-stored in the pituitary secretory granules. Here, we study molecular interactions between ACTH and β-endorphin and their colocalization in the form of amyloid aggregates. Although ACTH is known to be a part of ACTH-β-endorphin aggregate, ACTH alone cannot aggregate into amyloid under various plausible conditions. Using all atom molecular dynamics simulation we investigate the early molecular interaction events in the ACTH-β-endorphin system, β-endorphin-only system and ACTH-only system. We find that β-endorphin and ACTH formed an interacting unit, whereas negligible interactions were observed between ACTH molecules in ACTH-only system. Our data suggest that ACTH is not only involved in interaction with β-endorphin but also enhances the stability of mixed oligomers of the entire system

Occupational Exposure to Blood and Body Fluids Among Health Care Workers in a Teaching Hospital in Mumbai, India

<b>Objective:</b> Exposure to blood and body fluids is one of the hidden hazards faced by health care workers (HCWs). The objective of the present study was to estimate the incidence of such exposure in a teaching hospital. <b> Materials</b> <b> and</b> <b> Methods:</b> A cross-sectional study among a random sample of residents, interns, nurses and technicians (<i> n</i> = 830) was carried out in a teaching hospital to estimate the incidence of exposure to blood and body fluids in the preceding 12-month period. Self-reported occurrence and the circumstances of the same were recorded by face-to-face interviews using a semi-structured questionnaire. <b> Results:</b> The response rate to the study was 89.76&#x0025;. Occupational exposure to blood and body fluids in the preceding 12 months was reported by 32.75&#x0025; of the respondents. The self-reported incidence was the highest among the nurses. Needle-stick injury was the most common mode of such exposures (92.21&#x0025; of total exposures). Index finger and thumb were the commonest sites of exposure. Only 50&#x0025; of the affected individuals reported the occurrence to concerned hospital authorities. Less than a quarter of the exposed persons underwent post-exposure prophylaxis (PEP) against HIV, although the same was indicated in about 50&#x0025; of the affected HCWs based on the HIV status of the source patient. <b> Conclusions:</b> Occupational exposure to blood and body fluids was a common occurrence in the study sample. There was gross under-reporting of such incidents leading to a lack of proper PEP against HIV in 50&#x0025; of those in whom the same appeared to be indicated

Gender equality in primary immunisation

Context: Immunization, a well-known and effective method of preventing childhood illnesses is basic service under primary health care. Most surveys in India measure primary immunization coverage and quality, but no "Gender Equality." Aims: Assess "Gender Equality" in primary immunization with reference to coverage, quality, and place of immunization. Settings and Design: Cross-sectional survey in a primary health center, Pune, Maharashtra using World Health Organization 30-cluster sampling method with 14 beneficiaries (7 girls and 7 boys) to be selected from each cluster. Instead of 420 children, data collected for 345 children, as requisite numbers of children were not available in low population villages and also children whose mothers were not present during survey were excluded. Materials and Methods: Vaccination data collected from either records and/or history by mother. Children born on or between 13-09-2009 and 13-09-2010, were included. Statistical Analysis Used: SPSS 14.01 version with Chi-square as test of significance. Results: Of the study population, 171 (49.6%) were females and 174 (50.4%) males. A total of 64.1% children had immunization records with female proportion 69.0% and males 59.2%. Primary immunization coverage was 80.0%, with female proportion 82.5% and males 77.6%. One male child was completely unimmunized and remaining partially immunized, with unaware of schedule and illness of child being major reasons for partial immunization. There was no gender wise statistically significant difference observed in Primary Immunization with reference to coverage, quality, and place of immunization. Conclusions: Immunization coverage is nearing 85% benchmark with major contribution from Universal Immunization Program. Gender Equality observed in primary immunization. Preservation of immunization records by community and timely vaccinations are areas for improvement

Behavioral surveillance survey regarding human immunodeficiency virus/acquired immunodeficiency syndrome among high school and junior college students

Background and Aims: It is necessary to know the baseline knowledge, attitude, and practices about human immunodeficiency virus/acquired immunodeficiency syndrome among young people and the changes in these with intervention to guide prevention efforts. Methods: A cross-sectional pre- and post-survey with health education as a method of intervention was carried out in four different randomly selected schools and junior colleges among the Class IX-XII students of both sex. Instrument developed by the World Health Organization (WHO)/UNAIDS in their best practice recommendations was used for data collection. Results: Knowledge about all correct methods was present in 61.23% of the respondents. Knowledge of at least two methods of prevention was present in 70.31% of the respondents. Misconceptions about prevention were that good diet (33.42%), avoiding mosquito bite (49.71%) and avoiding public toilets (65.14%) could help in the prevention. With intervention, there was an improvement in the knowledge. However, the proportion of students with misconceptions did not come down. Correct knowledge about two methods of prevention also did not reach the WHO recommendation of 90%. Conclusion: It is very difficult to change the attitude and practices by a single health educational intervention and an ongoing behavior change communication is recommended
