in the properties of serotonin (5-HT) neurons of the raphe nuclei, the responsiveness to parachlorophenylalanine (PCPA) of 5-HT neurons in the dorsal and median raphe nuclei (DR and MR) and the nucleus raphe magnus (RMg) was analyzed by counting 5-HT-immunoreactive (5-HT-ir) cells. Go...
This immunohistochemical study confirmed our previous findings by conventional electron microscopy that there are marked sex differences in the proportions of PRL and GH cells in the adult mouse adenohypophysis; PRL cells are more abundant in the female mice, and GH cells are more abundant in the ...
And her parents are pushingfor the latter. Questions 12 to 15 are based on the conversation you havejust heard. 12. Why does the man seem to be distracted? 13. What does the woman, say she man should do? 14. What does the man say is part of his problem? 15. Why doesn't the ...
Moreover, human breast carcinomas are often infiltrated by stromal/immune cells secreting a wide spectra of cytokines. These might in turn regulate the activity of both immune and neoplastic cells. The present study was designed to examine the action of cytokines on 17beta-hydroxysteroid ...
The cells in the graft persist for a period of four months. After this period the cells are replaced by those of the host and in seven months there is almost complete replacement with host cells.关键词: CHROMOSOMES CORNEAL TRANSPLANTATION/experimental SEX CHARACTERISTICS ...

Sex-specific processing of the Drosophila exuperantia transcript is regulated in male germ cells by the tra-2 gene 来自 NCBI 喜欢 0 阅读量: 80 作者: T Hazelrigg,C Tu 摘要: The Drosophila exuperantia (exu) gene encodes overlapping sex-specific, germline-dependent mRNAs. In this work, ...
A diffusible substance, α factor, is produced constitutively by haploid yeast cells of α mating type and this factor specifically inhibits the division of a mating type cells. Experiments are presented which demonstrate that α factor arrests a cells as unbudded, mononucleate cells prior to the...
In order to investigate the function of gonadal somatic cells in the sex differentiation of germ cells, we produced chimera fish containing both male (XY) and female (XX) cells by means of cell transplantation between blastula embryos in the medaka, Oryzias latipes. Sexually mature chimera fish ...
The recent demonstration of estrogen receptors in bone derived cells has stimulated the study of direct effects of sex steroids on bone. We have shown direct stimulation of proliferation by 17 beta-estradiol (E2) of ROS 17/2.8 rat osteogenic osteosarcoma cells, and other bone-derived cells in ...
