Food restriction alters the diurnal distribution of sleep in rats.
The purpose of the present study was to determine the effects of restricting food and water intake to the light period on sleep and brain temperature (Tbr). Sprague-Dawley male rats were anesthetized and provided with electrodes and thermistors for electroencephalographic (EEG) and Tbr recordings. Baseline recordings were performed after a 3-week recovery period. After baseline recordings, acce...
متن کاملSleep restriction acutely impairs glucose tolerance in rats
Chronic sleep curtailment in humans has been related to impairment of glucose metabolism. To better understand the underlying mechanisms, the purpose of the present study was to investigate the effect of acute sleep deprivation on glucose tolerance in rats. A group of rats was challenged by 4-h sleep deprivation in the early rest period, leading to prolonged (16 h) wakefulness. Another group of...
متن کاملBiphasic changes in heart performance with food restriction in rats.
To examine effects of food restriction resembling very-low-calorie dieting on heart performance, normal rats were fed 25% of ad libitum food intake for 14 days. Although heart weight decreased (P < 0.05) after 5 days, left ventricular systolic pressure as well as rates of pressure development and fall were increased (P < 0.05) at 7 days and decreased (P < 0.05) after 14 days. Systolic and diast...
متن کاملElevated ghrelin predicts food intake during experimental sleep restriction
OBJECTIVE Sleep curtailment has been linked to obesity, but underlying mechanisms remain to be elucidated. This study assessed whether sleep restriction alters 24-h profiles of appetite-regulating hormones ghrelin, leptin, and pancreatic polypeptide during a standardized diet and whether these hormonal alterations predict food intake during ad libitum feeding. METHODS Nineteen healthy, lean m...
متن کاملRepeated sleep restriction in rats leads to homeostatic and allostatic responses during recovery sleep.
Recent studies indicate that chronic sleep restriction can have negative consequences for brain function and peripheral physiology and can contribute to the allostatic load throughout the body. Interestingly, few studies have examined how the sleep-wake system itself responds to repeated sleep restriction. In this study, rats were subjected to a sleep-restriction protocol consisting of 20 h of ...
