Alginate-based microcapsules for immunoisolation of pancreatic islets. Longevity, competition and musth: a long-term perspective on male reproductive strategies. The present study was designed to deliver sex steroids by a functional construct fabricated using encapsulation techniques.
Falck B. In castrated murine models, alterations are observed in the methylation patterns in the anteroventral and periventricular nucleus, which can be reverted by injecting testosterone. Drummond AE. Saunders Company. Annals of the New York Academy of Sciences : — An unfertilized egg will cause estrogen and progesterone levels to decline.

Higher doses, however, may suppress production of the sex steroids estradiol and progesterone. Bioartificial liver: implanted artificial cells microencapsulated living hepatocytes increases survival of liver failure rats. To ensure that both endocrine cells possess other essential cellular components for steroidogenesis, the granulosa and theca cells were screened for the expression of cell-specific gonadotropin receptor and steroidogenic enzyme by immunofluorescence staining.
To evaluate the endocrine functions of un-encapsulated and encapsulated ovarian cells, the levels of E 2P 4activin and inhibin were measured in the culture media.
In addition, cells in the multilayer microcapsules also secreted activin and inhibin in vitro. These models permit investigators to observe, for the most part, the independent effects of sex chromosomes and hormones on physiologic and pathophysiologic processes. If I were a sperm, what path would I take through the female reproductive system?
To fully capture between-sex variability, it may be of use to compare men to two or more groups of women. Site of production of oestrogen in rat ovary as studied in micro-transplants. Lancet 1 : —
