The role of glucagon-like peptide-1 (GLP-1) on gonadotropin-releasing hormone (GnRH) secretion was investigated in ovariectomised (OVX) ewes, which GnRH and luteinising (LH) had been restrained by treatment with oestrogen progesterone. Guide tubes for microinjection were placed above the median eminence (ME) animals allowed to recover 1 month. Jugular venous blood samples taken via cannulae at ...

migratory birds can become long-distance vectors for a wide range of microorganisms. the objective of the present study was to investigate the presence of cryptococcus neoformans in the cloacae, crop and nasal cavity of migratory birds in order to assess their role as potential reservoirs and/or mechanical vectors of human and animal cryptococcosis. a total of 700 samples (cloacae, crops and na...

objective(s): ghrelin is a peptide hormone that has been shown to have numerous central and peripheral effects. the central effects including gh secretion, food intake, and energy homeostasis are partly mediated by kiss1- kissr signaling pathway. ghrelin and its receptor are also expressed in the pancreatic islets. ghrelin is one of the key metabolic factors controlling insulin secretion from t...
