Gonadotropins
This exceptionally well done book organizes the proceedings of the International Symposium on Gonadotropins held at the New York Hospital Bicentennial Celebration in 1971 into 58 essays which survey the chemistry and physiology of FSH, LH, and prolactin. The book's major attribute is the special care taken to present gonadotropin research in perspective. Thus, the first essay, if not all of the...
متن کاملGonadotropins
Five years after the demonstration of anterior pituitary dominance over the gonads by the Smiths and Aschheim and Zondek, Moore and Price asserted the classic principle of the reciprocal "feedback" relationship between the secretions of these organs. Three decades later continued investigation of this interdependence has culminated in two major advances in clinical medicine: steroid inhibition ...
متن کاملGonadotropins regulate ovarian germ cell mitosis/meiosis decision in the embryonic chicken.
Gonadotropins are required for gametogenesis but in embryonic gonads this mechanism is not well understood. Here we use chicken embryos to investigate the mechanism that gonadotropins regulate the ovarian germ cell mitosis/meiosis decision. Treatment with follicle-stimulating hormone (FSH) delayed germ cell meiosis entry and promoted their proliferation. This action was blocked by an aromatase ...
متن کاملDetection of Salmonella sp in chicken cuts using immunomagnetic separation
The immunomagnetic separation (IMS) is a technique that has been used to increase sensitivity and specificity and to decrease the time required for detection of Salmonella in foods through different methodologies. In this work we report on the development of a method for detection of Salmonella in chicken cuts using in house antibody-sensitized microspheres associated to conventional plating in...
متن کاملSeparation of ovotransferrin and ovomucoid from chicken egg white.
Ovotransferrin and ovomucoid were separated using 2 methods after extracting the ovotransferrin- and ovomucoid-containing fraction from egg white. Diluted egg white (2×) was added to Fe(3+) and treated with 43% ethanol (final concentration). After centrifugation, the supernatant was collected and treated with either a high-level ethanol (61% final concentration) or an acidic salt combination (2...
