Human GnRH deficiency: a unique disease model to unravel the ontogeny of GnRH neurons.
Evolutionary survival of a species is largely a function of its reproductive fitness. In mammals, a sparsely populated and widely dispersed network of hypothalamic neurons, the gonadotropin-releasing hormone (GnRH) neurons, serve as the pilot light of reproduction via coordinated secretion of GnRH. Since it first description, human GnRH deficiency has been recognized both clinically and genetic...
متن کاملInteractions Between Reproductive and Immune Systems During Ontogeny: Roles of GnRH, Sex Steroids, and Immunomediators
Reproduction is an essential function of every animal species, and its realization depends on a complex of interrelated neural, endocrine, immune, and behavioral reactions. It is now accepted that the neuroendocrine system (including its reproductive component) and the immune system have a reciprocal regulatory influence development and functioning during preand postnatal ontogeny (Watanobe & H...
متن کاملESTRUS SYNCHRONIZATION SYSTEMS: GnRH
Development of methods to manipulate the estrous cycle so that all cows are in estrus during a short, predefined period (synchronized estrus) while maintaining normal fertility has been a difficult goal to achieve, but has resulted in the creation of valuable synchronization protocols that are available to producers today. Although implementation of estrus synchronization and AI will improve th...
متن کاملREVIEW OF ESTROUS SYNCHRONIZATION SYSTEMS : GnRH
Synchronization of estrus contributes to optimizing the use of time, labor, and financial resources by shortening the calving season, in addition to increasing the uniformity of the calf crop. The major limitation of estrus-synchronization programs is their inability to induce a potentially fertile estrus and ovulation in noncycling cattle (i.e., prepubertal heifers and anestrous suckling cattl...
متن کاملThe evolution of classification systems: Ontogeny of the UDC
To classify is to put things in meaningful groups, but the criteria for doing so can be problematic. Study of evolution of classification includes ontogenetic analysis of change in classification over time. We present an empirical analysis of the UDC over the entire period of its development. We demonstrate stability in main classes, with major change driven by 20 century scientific development...
