OBJECTIVE Glucocorticoid excess is characterized by increased adiposity, skeletal myopathy, and insulin resistance, but the precise molecular mechanisms are unknown. Within skeletal muscle, 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) converts cortisone (11-dehydrocorticosterone in rodents) to active cortisol (corticosterone in rodents). We(More)
Neuropeptide Y (NPY) concentrations were measured by radioimmunoassay in eight microdissected hypothalamic regions of obese (fa/fa) and lean (Fa/?) Zucker rats. Freely fed obese rats showed significant (40-100%) increases in NPY concentrations in several regions, notably the paraventricular, ventromedial, and dorsomedial nuclei and the arcuate(More)
Increased hypothalamic neuropeptide Y levels have previously been demonstrated in several hypothalamic nuclei of the (fa/fa) Zucker rat. This study set out to characterise hypothalamic NPY receptors in both genotypres and to study the effect of exogenous NPY on feeding behavior in these rats. Spontaneous daytime food intake was raised in the obese rat (p(More)
Using immunohistochemical techniques, a large number of serotonergic paracrine cells were identified in the urethral mucosa of the female rat. The functional significance of these cells was investigated. A model for the study of sexual climax in the anesthetized, acutely spinalized female rat was used. In this model, distension of the urethra with saline(More)
