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...
15 صفحه اولNeuropeptides and thymic hormones in the Xenopus thymus.
T-cell development is characterised by a complex series of events in the thymus, which results in the development of self-restricted immunocompetent lymphocytes. We have previously reported the expression of neuropeptides in the thymus of various species, highlighting the evolutionary importance of neuroendocrine interactions in thymocyte development. Despite the many physiological and function...
متن کاملBiological Actions of Sex Hormones
313 personal effort as well as personal desire must be active if an effective program is to develop. A case is made to the end that effort be directed to improve health during the latter half of the lifespan of the individual and not to continue focusing all attention on childhood and adolescence. The author urges us to reconsider policy in connection with a constructive medical program, to rec...
متن کاملSex hormones have pervasive effects on thymic epithelial cells
The goal of our study was to evaluate at the systems-level, the effect of sex hormones on thymic epithelial cells (TECs). To this end, we sequenced the transcriptome of cortical and medullary TECs (cTECs and mTECs) from three groups of 6 month-old mice: males, females and males castrated at four weeks of age. In parallel, we analyzed variations in the size of TEC subsets in those three groups b...
متن کاملUranyle Complexes: synthesis, evaluation of biological activity
In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...
