Food deprivation can affect performance on difficult cognitive task, such as the delayed nonmatch-to-place T-maze task (DNMT). The importance of food deprivation on maintaining high motivation for DNMT task has been emphasized, but not many studies have investigated the optimal conditions for depriving rodents to maximize performance. Establishing appropriate conditions for food deprivation is ...
Six adult female albino rats were subjected to operations known to increase the frequency of wheel-running. Operations included limited access to wheel, food deprivation, and protracted maintenance on a 24-hr feeding schedule. A distributional analysis of response duration, burst duration, and inter-burst interval showed that the increased frequency in all cases arose mainly from a shortening o...
Background and Aim: Memory and learning are the putative targets for the stressors by some biochemical reactions such as glucocorticoid hormones. Intermittent feeding is a kind of dietary behavior with some reported positive efficacy on the various systems of the body. The aim of this study was the evaluation of intermittent feeding on learning and spatial memory in the male mice under chronic ...
When a pig is deprived of drinking water, a deficit of body water develops that is corrected when the pig drinks to satiation. If food is available during the deprivation, the stimulus to drinking is plasma hyperosmolality. Because of the delay in correction of plasma hyperosmolality as ingested water is slowly absorbed, it has been thought that a rapid inhibitory signal from the digestive trac...
In mammals, hypothalamic control of food intake involves counterregulation of appetite by an orexigenic peptides such as corticotropin-releasing factor (CRF), and orexigenic peptides such as neuropeptide Y (NPY). Glucocorticoids also stimulate food intake by inhibiting CRF while facilitating NPY actions. To gain a better understanding of the diversity and evolution of neuroendocrine feeding con...
OBJECTIVE To examine the relationship between density of fast food restaurants and measures of social and material deprivation at the community level in Nova Scotia, Canada. METHODS Census information on population and key variables required for the calculation of deprivation indices were obtained for 266 communities in Nova Scotia. The density of fast food restaurants per 1000 individuals fo...
BACKGROUND The goals of the study are evaluation the effects of food deprivation and isolation situation as a social stress on fertility; and in the following, investigation of the improving effect of melatonin as an antioxidant component. MATERIALS AND METHODS In this experimental study, We investigated histopathological and serological effects of melatonin and social stress (food deprivatio...
Abstract Background: Nowadays, working long hours and shift work are inevitable, even though these working schedules are associated with several physical and mental effects. Gastrointestinal complaints are common among their physical effects. Recent studies have shown organoprotective effect of melatonin in gastrointestinal tract. In this study we investigated gastric mucosal damage due to par...
