OBJECTIVE AND DESIGN The objective of the study was to find out the prevalence of overweight, obesity, undernutrition and physical activity status in the urban populations of India. Cross-sectional surveys were conducted in 6-12 urban streets in each of five cities in five different regions of India using a common study protocol and criteria of diagnosis.(More)
PURPOSE Single nucleotide polymorphism (SNP) at position -309 (T309G) in MDM-2 promoter induces tumor formation in the individuals possessing inherited p53 mutations. The present study was undertaken to investigate the association of MDM-2 SNP309, p53 Arg72Pro, and p53 intron-6 G/A polymorphism with total, premenopausal, and postmenopausal breast cancer(More)
Water deficit stress (WDS) is a serious constraint to wheat productivity in rain-fed and limited irrigation environments. Identifying genomic regions responsible for grain yield (GY) under WDS will aid in understanding the genetics of drought tolerance (DT) and development of DT cultivars. A population of 206 recombinant inbred lines derived from WL711/C306(More)
OBJECTIVES Cardiometabolic diseases are increasing disproportionately in South Asia compared with other regions of the world despite high levels of vegetarianism. This unexpected discordance may be explained by differences in the healthfulness of vegetarian and non-vegetarian diets in South Asia compared with the United States. The aim of this study was to(More)
The objectives of the study were to assess the prevalence of urinary incontinence symptoms during pregnancy in a racially mixed sample and to identify potential predisposing variables. Five hundred and twenty-three women were interviewed in the hospital on postpartum day 2 or 3 and by telephone at 6-week follow-up. A significantly larger proportion of white(More)
BACKGROUND Clinical studies have suggested that depression is common among patients with type 2 diabetes (T2D). Depression is an important factor which affects the management and complications of diabetes. However, the available data regarding its prevalence in India are limited. OBJECTIVES To estimate the prevalence of depression in patients in India(More)
NAD(P)H:quinone oxidoreductase 1 (NQO1) and cytochrome P450 1A2 (CYP1A2) are involved in the metabolism of estrogens. Genetic polymorphisms in these genes may lead to interindividual variation in breast cancer susceptibility. This study was undertaken to investigate the association of NQO1 exon 6 proline187serine (C609T) and CYP1A2 exon 2(More)
Drought is a major constraint to maintaining yield stability of wheat in rain fed and limited irrigation agro-ecosystems. Genetic improvement for drought tolerance in wheat has been difficult due to quantitative nature of the trait involving multiple genes with variable effects and lack of effective selection strategies employing molecular markers. Here, a(More)
In this tutorial review, we discuss the defect chemistry of selected amphoteric oxide semiconductors in conjunction with their significant impact on the development of renewable and sustainable solid state energy conversion devices. The effect of electronic defect disorders in semiconductors appears to control the overall performance of several solid-state(More)
Development of chemically stable proton conductors for solid oxide fuel cells (SOFCs) will solve several issues, including cost associated with expensive inter-connectors, and long-term durability. Best known Y-doped BaCeO3 (YBC) proton conductors-based SOFCs suffer from chemical stability under SOFC by-products including CO2 and H2O. Here, for the first(More)
