Role of apoplastic calcium during germination and initial stages of seedling establishment in Vigna radiata seeds.

Calcium (Ca) is implicated in the initial phase of seed germination and seedling establishment. It is stored complexed with phytic acid during seed development and released by phytase action during germination. We observed phytase activity 18 h post-imbibition (PI) in Vigna seeds, while radicle protrusion occurred approximately 12 h PI.

Inhibition of Heat Shock proteins HSP90 and HSP70 induce oxidative stress, suppressing cotton fiber development.

Cotton fiber is a specialized unicellular structure useful for the study of cellular differentiation and development. Heat shock proteins (HSPs) have been shown to be involved in various developmental processes. Microarray data analysis of five Gossypium hirsutum genotypes revealed high transcript levels of GhHSP90 and GhHSP70 genes at different stages of fiber development, indicating their importance in the process.

Dietary supplementation of n-3 polyunsaturated fatty acid alters endometrial expression of genes involved in prostaglandin biosynthetic pathway in breeding sows (Sus scrofa).

The present investigation was designed to study the effect of dietary supplementation of omega-3 (n-3) PUFA on endometrial expression of fertility-related genes in breeding sows. Sixteen crossbred sows were randomized to receive diets containing 4% (wt/wt) flaxseed oil as n-3 PUFA source (TRT group) or iso-nitrogenous, iso-caloric standard control diet (CON group), starting from the first day of estrus up to 40 days and were artificially bred on the second estrus. Endometrial samples were collected during days 10-11 and 15-16 post-mating for studying relative expression profile of candidate genes viz.

Development of parthenote following in vivo transfer of embryos in Capra hircus.

The aim of this study is to generate parthenogenetic embryos from chemically activated in vitro matured caprine oocytes and to study the in vivo developmental potency of such embryos. The parthenogenetic embryos (2-8 and 16 cells to morula stage) were surgically transferred in 26 recipients. Pregnancy in recipients following embryo transfer was monitored by ultrasonography.

Groundwater contaminated with hexavalent chromium [Cr (VI)]: a health survey and clinical examination of community inhabitants (Kanpur, India).

Background: We assessed the health effects of hexavalent chromium groundwater contamination (from tanneries and chrome sulfate manufacturing) in Kanpur, India.

Methods: The health status of residents living in areas with high Cr (VI) groundwater contamination (N = 186) were compared to residents with similar social and demographic features living in communities having no elevated Cr (VI) levels (N = 230). Subjects were recruited at health camps in both the areas.

Genetic predisposition for dermal problems in hexavalent chromium exposed population.

We studied the effect of genetic susceptibility on hexavalent chromium induced dermal adversities. The health status of population was examined from the areas of Kanpur (India) having the elevated hexavalent chromium levels in groundwater. Blood samples were collected for DNA isolation to conduct polymorphic determination of genes, namely: NQO1 (C609T), hOGG1 (C1245G), GSTT1, and GSTM1 (deletion).

Interferon stimulated gene 15 (ISG15): molecular characterization and expression profile in endometrium of buffalo (Bubalus bubalis).

Interferon stimulated gene 15 (ISG15), one of the several proteins induced by conceptus derived Type I and/or a Type II interferon (IFN), is implicated as an important factor in determining the uterine receptivity and conceptus development. However, presence as well as specific role of the ISG15 in buffalo (Bubalus bubalis) reproduction is yet to be elucidated. In the present study, both genomic and cDNA sequences of bubaline (bu) ISG15 were cloned and investigated for its expression in different tissues of female reproductive tract of buffalo.

Impact of norgestomet supplementation during early luteal phase on subsequent luteal profiles and conception rate in buffalo: a preliminary study.

The current study was aimed to establish the impact of progesterone supplementation (norgestomet progestagen) between days 4 to 10 post-ovulation on subsequent luteal profile and conception rate in buffaloes. The 28 Murrah buffaloes of second to fourth parity, having normal reproductive organs, were estrus synchronized by double PGF(2α) protocol at 11 days apart. The buffaloes were inseminated during mid- to late estrus and thereafter repeated at 24 h interval.

Molecular characterization and expression profile of uterine serpin (SERPINA14) during different reproductive phases in water buffalo (Bubalus bubalis).

Uterine serpins (SERPINA14) play important roles during pregnancy in the farm animals. In this study, we have cloned and characterized cDNA sequence encoding the bubaline SERPINA14. We also studied its spatio-temporal expression in the uterine endometrium.

Study of genetic polymorphism in solvent exposed population and its correlation to in vitro effect of trichloroethylene on lymphocytes.

Trichloroethylene (TCE) is major industrial pollutant that contaminate environment. Its exposure may lead to hepato-renal toxicity along with the cancer progression. Although extensive research is done on its toxicity still not much is known about its genotoxic potential on humans in relation to genetic polymorphism.

GSTM1, GSTT1, and GSTP1 polymorphism in north Indian population and its influence on the hydroquinone-induced in vitro genotoxicity.

Glutathione S transferase (GST) gene polymorphism examined among north Indians and correlated with hydroquinone (HQ) genotoxicity to help in clinical prediction of susceptibility of HQ toxicity. Lymphocytes of individuals with/without GSTM1, GSTT1, and GSTP1 (ile/ile or val/val) were exposed to HQ (20, 40, or 80 microM) and examined chromosomal aberrations (CA) or cytokinesis-block micronucleus assays. Among north Indians the frequencies of GSTM1 (null), GSTT1 (null), and both null were found to be 41.

Lung cancer risk in north Indian population: role of genetic polymorphisms and smoking.

Lung cancer (LC) is the leading cause of cancer-related mortality in developing as well as developed countries. Life style choices, particularly tobacco smoking, have been implicated as the main cause in the development of the LC. Despite the fact that majority cases of the LC occur among smokers, only 1-15% of smokers develop LC.

High nasopharyngeal carriage of beta-lactamase-negative ampicillin-resistant Haemophilus influenzae in north Indian school-going children.

Development of ampicillin resistance in Haemophilus influenzae is a cause of serious concern. Ampicillin resistance in H influenzae is beta-lactamase mediated except in some isolates. Two important issues related to beta-lactamase-negative ampicillin-resistant (BLNAR) strains while choosing therapy for infections caused by H.
