Effect of heat stress on physio-biochemical characteristics of chickpea (Cicer arietinum) genotypes
A study was conducted with three chickpea genotypes Pusa 256, RSG 888 and JG 11 to study the effect of high temperature stress on various physiological and biochemical parameters. In all the chickpea genotypes high temperature stress decreased RWC, MSI, Chl content, dry matter, leaf area and increased activity of antioxidant enzymes such as POX, GR, and SOD. RSG 888 possessed better seedling growth parameters under high temperature as compared to Pusa 256 and JG 11
Institutional delivery in public and private sectors in South Asia: a comparative analysis of prospective data from four demographic surveillance sites
BACKGROUND: Maternity care in South Asia is available in both public and private sectors. Using data from demographic surveillance sites in Bangladesh, Nepal and rural and urban India, we aimed to compare institutional delivery rates and public-private share. METHODS: We used records of maternity care collected in socio-economically disadvantaged communities between 2005 and 2011. Institutional delivery was summarized by four potential determinants: household asset index, maternal schooling, maternal age, and parity. We developed logistic regression models for private sector institutional delivery with these as independent covariates. RESULTS: The data described 52 750 deliveries. Institutional delivery proportion varied and there were differences in public-private split. In Bangladesh and urban India, the proportion of deliveries in the private sector increased with wealth, maternal education, and age. The opposite was observed in rural India and Nepal. CONCLUSIONS: The proportion of institutional delivery increased with economic status and education. The choice of sector is more complex and provision and perceived quality of public sector services is likely to play a role. Choices for safe maternity are influenced by accessibility, quantity and perceived quality of care. Along with data linkage between private and public sectors, increased regulation should be part of the development of the pluralistic healthcare systems that characterize south Asia

Prevalence and determinants of caesarean section in private and public health facilities in underserved South Asian communities: cross-sectional analysis of data from Bangladesh, India and Nepal.
OBJECTIVES: To describe the prevalence and determinants of births by caesarean section in private and public health facilities in underserved communities in South Asia. DESIGN: Cross-sectional study. SETTING: 81 community-based geographical clusters in four locations in Bangladesh, India and Nepal (three rural, one urban). PARTICIPANTS: 45,327 births occurring in the study areas between 2005 and 2012. OUTCOME MEASURES: Proportion of caesarean section deliveries by location and type of facility; determinants of caesarean section delivery by location. RESULTS: Institutional delivery rates varied widely between settings, from 21% in rural India to 90% in urban India. The proportion of private and charitable facility births delivered by caesarean section was 73% in Bangladesh, 30% in rural Nepal, 18% in urban India and 5% in rural India. The odds of caesarean section were greater in private and charitable health facilities than in public facilities in three of four study locations, even when adjusted for pregnancy and delivery characteristics, maternal characteristics and year of delivery (Bangladesh: adjusted OR (AOR) 5.91, 95% CI 5.15 to 6.78; Nepal: AOR 2.37, 95% CI 1.62 to 3.44; urban India: AOR 1.22, 95% CI 1.09 to 1.38). We found that highly educated women were particularly likely to deliver by caesarean in private facilities in urban India (AOR 2.10; 95% CI 1.61 to 2.75) and also in rural Bangladesh (AOR 11.09, 95% CI 6.28 to 19.57). CONCLUSIONS: Our results lend support to the hypothesis that increased caesarean section rates in these South Asian countries may be driven in part by the private sector. They also suggest that preferences for caesarean delivery may be higher among highly educated women, and that individual-level and provider-level factors interact in driving caesarean rates higher. Rates of caesarean section in the private sector, and their maternal and neonatal health outcomes, require close monitoring
Effect of Bistorta affinis (D. Don) and Malcolmia cabulica (Boiss) Essential Oils on Human and Foodborne Pathogens, Insects and Termites
This current study investigates the biological efficiency of essential oils extracted from Bistorta affinis and Malcolmia cabulica on human and foodborne pathogens as well as against insects and termites. The oils were obtained by steam distillation using a Clevenger-type system and analyzed for their constituents using GC-MS. Twenty compounds were identified, wherein carvacrol and thymol were the main constituents in both plants. Essential oils exhibited significant activity against all tested foodborne bacteria, fungi, and other pathogens. In addition, essential oils from both plants have shown promising activity against all tested insects, which is a positive sign of being used as an insect repellent. In contrast, no activity was observed against termites. The bioactivities are mainly due to carvacrol and thymolâs levels in the essential oils that known for their effectiveness against foodborne pathogens and pests. The present study constitutes a basis for further investigation and development of bioactive compounds in Bistorta affinis and Malcolmia cabulica
The Equity Impact of Community Women's Groups to Reduce Neonatal Mortality: A Meta-analysis of Four Cluster Randomized Trials
Socioeconomic inequalities in neonatal mortality are substantial in many developing countries. Little is known about how to address this problem. Trials in Asia and Africa have shown strong impacts on neonatal mortality of a participatory learning and action intervention with womenâs groups. Whether this intervention also reduces mortality inequalities remains unknown. We describe the equity impact of this womenâs groups intervention on the neonatal mortality rate (NMR) across socioeconomic strata.
We conducted a meta-analysis of all four participatory womenâs group interventions that were shown to be highly effective in cluster randomized trials in India, Nepal, Bangladesh and Malawi. We estimated intervention effects on NMR and health behaviours for lower and higher socioeconomic strata using random effects logistic regression analysis. Differences in effect between strata were tested.
Analysis of 69120 live births and 2505 neonatal deaths shows that the intervention strongly reduced the NMR in lower (50â63% reduction depending on the measure of socioeconomic position used) and higher (35â44%) socioeconomic strata. The intervention did not show evidence of âelite-captureâ: among the most marginalized populations, the NMR in intervention areas was 63% lower [95% confidence interval (CI) 48â74%] than in control areas, compared with 35% (95% CI: 15â50%) lower among the less marginalized in the last trial year (P-value for difference between most/less marginalized: 0.009). The intervention strongly improved home care practices, with no systematic socioeconomic differences in effect.
Participatory womenâs groups with high population coverage benefit the survival chances of newborns from all socioeconomic strata, and perhaps especially those born into the most deprived households
Women candidates and party nomination trends in India: evidence from the 2009 general election
More women MPs than ever before were elected to the lower house of the national parliament of India in the 2009 General Election. Yet, the increase in womenâs presence in the Lok Sabha cannot necessarily be attributed to the increased willingness of political parties to field more women candidates, despite rhetorical party political support for increasing womenâs participation in political institutions. This article analyses party political nomination of women as candidates in the 2009 election, and finds significant variations in levels of nomination across parties and across Indiaâs states. The article also examines in detail the nomination of female candidates by the two largest political parties, the Indian National Congress party and the Bharatiya Janata Party, both of which support proposals for introducing reserved seats for women in national and state legislatures. The findings reject the proposition that parties only nominate women in unwinnable seats, but finds support for the proposition that parties are risk averse when it comes to nominating women, and that this can restrict the number of women nominated for election. The article concludes with some further questions for future research on gender and political recruitment in India
White Electroluminescence Using ZnO Nanotubes/GaN Heterostructure Light-Emitting Diode
We report the fabrication of heterostructure white lightâemitting diode (LED) comprised of n-ZnO nanotubes (NTs) aqueous chemically synthesized on p-GaN substrate. Room temperature electroluminescence (EL) of the LED demonstrates strong broadband white emission spectrum consisting of predominating peak centred at 560 nm and relatively weak violetâblue emission peak at 450 nm under forward bias. The broadband EL emission covering the whole visible spectrum has been attributed to the large surface area and high surface states of ZnO NTs produced during the etching process. In addition, comparison of the EL emission colour quality shows that ZnO nanotubes have much better quality than that of the ZnO nanorods. The colour-rendering index of the white light obtained from the nanotubes was 87, while the nanorods-based LED emit yellowish colour
