OBJECTIVES The purpose of this study was to determine the paired consequences of food restriction and paradoxical sleep deprivation on lipid profile and spontaneous glucose levels in male rats. METHOD Food restriction began at weaning, with 6 g of food being provided per day, which was subsequently increased by 1 g per week until reaching 15 g per day by the eighth week. At adulthood, both ra...

Objective- Evaluation of the effect of different fasting times on the quality of propofol total intravenous anesthesia (TIVA) and recovery features. Design- Experimental prospective design. Animals- Fifteen lambs. Procedures- Fifteen lambs that anesthetized for carotid translocation surgery were included in this current study and allocated in to three groups randomly. In Group 1, food was withh...

Introduction: The brain glutamate system plays a central role in response to stress. This study examines the effect of memantine (a NMDA glutamate receptor antagonist) on stress from plantar electrical shock in male NMRI mice (Pasture Institute, Iran), weighing 25-30 g (n=6/group). Methods: The nucleus accumbens was bilaterally cannulated in a group of animals, and seven days later, differen...

The comparative approach to food safety assessment is based on the idea that the safety of a new food can largely be determined by its comparison to the benchmark of commonly consumed foods already in the food supply (also called the 'conventional counterpart'). Any differences between the new food and its conventional counterpart are evaluated to determine their relevance to human health and s...

We tested the hypothesis that cattle aided by visual cues would be more efficient than uncued animals in locating and consuming foods placed in either fixed or variable locations within a 0.64-ha experimental pasture. Eight yearling steers were randomly selected and trained to associate traffic barricades and traffic cones with high- (oat-barley mixture) and low- (straw) quality foods, respecti...

previous studies in humans and animals have reported that nicotine administration decreases body weightand caloric intake. opiate and cigarette have been used concomitantly as drug abuse. the aim of the present study was, therefore, to analyze the effect of chronic co-administration of nicotine and morphine on food intake, body weight and on some feeding-associated peptides. all experiments wer...

The patterning of feeding and the quantity eaten in Aplysia californica with ad libitum food access cannot be explained by the effects of three variables previously shown to control the patterning of consummatory feeding responses and the quantity eaten in animals hand-fed individual meals. Feeding in ad libitum conditions is regulated primarily by varying the time between feeding bouts rather ...
