It has recently been reported that injection of male sex hormone simultaneously with estrin into normal female rats partially suppressed the characteristic histologic reaction of the anterior pituitary to estrin. 1 2 The degree of weight increase in the pituitary and the degree of degranulation of the...
For to understand male youngsters sex hor- mone level and its relationship with sex and physi- cal development,using radioimmunoassay,serum sex hormone FSH,LH,PRL,T E2 were deter- mined in 8-19 years old 128 male youngsters.And their sex development degree and physical deelop- ment status ...
At the small growth stage, three kinds of the sex steroid receptors usually were localized in the cytoplasm or nuclear membrane of oogonia and early primary oocyte, and localized in the cytoplasm and nucleoplasm of oocytes at the large growth stage and mature stage. In male, three kinds of ...
Effect of streptozotocin-induced diabetes on sex differences in biliary lipid secretion in the rat Diabetes mellitus is often associated with lipid abnormalities that may differ with sex. In this work we studied biliary lipid secretion in male and female......
(hyperlipidic) diet induced hormone distribution changes, affected by sex, which hint at sex-related structural differences in RBC membranes; c) We postulate that the RBC compartment may contribute to maintain free (i.e., fully active) sex hormone levels in a way similar to plasma proteins ...
In cattle, nearly all heifers born co-twin to a male are freemartins, XX/XY chimeras that exhibit a characteristic masculinized phenotype. However, in sheep, while litters containing males and females are common, freemartins are relatively rare. The primary aim of this study was to determine...
CONCLUSIONS: These data demonstrate that the gonadal hormones influence the amount, distribution, and intensity of sleep but do not account for all sex differences in the sleep-wake cycle. 展开 关键词: Sleep sleep deprivation sex gonadal hormone mouse testis ovary ...
This study aimed to determine the sex specificity and expression pattern of foxl2 and cyp19a1a genes in great sturgeon Huso huso gonads during gonadal sex differentiation and development. The results revealed that foxl2 and cyp19a1a mainly expressed in female gonads and during gonad development th...

In mice with a similar phenotype, the ablation of M33, an ortholog of Drosophila Polycomb, causes male-to-female sex reversal. The analysis of the human homolog of M33, Chromobox homolog 2 (CBX2), in this girl revealed loss-of-function mutations that allowed us, by placing CBX2 upstream...
