Mature male Sprague-Dawley (SD) and Long-Evans (LE) rats were instrumented with telemetry transmitters for measurement of heart rate (HR) and housed in room calorimeters for assessment of food intake and oxygen consumption (Vo(2)) at standard laboratory temperatures (23 degrees C) to examine physiological responses to caloric restriction (CR; 60% of(More)
Melanin-concentrating hormone (MCH) is a cyclic 19-amino acid neuropeptide exclusively synthesized in the lateral hypothalamic area (LHA) and the zona incerta (ZI) that has been implicated in the regulation of energy balance. Despite what is known about the orexigenic effect of MCH, whether MCH has distinct cardiovascular and metabolic effects has yet to be(More)
Estradiol exerts an inhibitory effect on food intake via interactions with anorexigenic peptides, like cholecystokinin, that function to decrease meal size. It is currently unknown whether estradiol also interacts with orexigenic compounds implicated in the physiological control of food intake. Thus, the primary goal of this study was to determine whether(More)
We studied the effect of arcuate nucleus (ARC) lesions induced pharmacologically by the perinatal treatment of monosodium l-glutamate (MSG) on the cardiovascular, metabolic, and behavioral responses to fasting. Saline and MSG-treated male Sprague-Dawley rats were instrumented with telemetry devices for measurement of mean arterial pressure (MAP) and heart(More)
