comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Bovine oocytes in early antral follicles grow in serum-free media: effect of hypoxanthine on follicular morphology and oocyte growth.
Some culture systems have been shown to support oocyte growth in mice, although there has been little success in applying these systems to other species. In the present study, we compared three culture conditions for growing bovine oocytes and examined the effect of hypoxanthine on oocyte growth. In the first experiment, early antral follicles, 0.4-0.7 mm in diameter were collected, and oocyte-...
متن کاملP-46: Proliferative Activity of Follicular Cells in Adult Mouse Ovary Following Administration of Exogenous Nicotine
Background: Nicotine can induce sub fertility and infertility in females. The aim of this study was to determine the effect of nicotine on follicular cells proliferative activity in mouse ovary. Materials and Methods: Female adult NMRI mice were divided into two groups. Animals in control group received vehicle, however in experimental group, animals were treated with 0.4mg/kg of nicotine for 1...
متن کاملOccurrence of multi-oocyte follicles in aquaporin 8-deficient mice
BACKGROUND Granulosa cells play a key role in folliculogenesis and female reproduction. Our previous study demonstrated that water channel aquaporin-8 (AQP8) is expressed in mouse follicular granulosa cells and is an important determinant of granulosa cell apoptosis and follicular maturation. More roles of AQP8 in folliculogenesis remain to be determined. FINDINGS The present study reports th...
