The course of repletion and the effects of food deprivation on meal size were explored in three experiments on larvae of Chrysopa carnea (Neuroptera). Feeding to repletion was found to occur within the first 30 min of exposure to food. Meal size increased as an ogival function of deprivation, up to the limit of gut capacity. Behavioral components involved in the initiation of feeding were littl...

Experiment 1 investigates effects of different levels of start-box novelty and complexity on rats' running speed to food; Experiment 2 investigates effects of 2 degrees of goal-box novelty and complexity on the persistence of eating in the start box. Both experiments are conceptualized in a framework focusing attention on shifts from one behavior (ongoing) to another (alternative) in which late...

as cost of living rises and people’s wages / salaries do not cover their basic food and dietary needs, interest in parttime farming has risen. part-time farming activities are being practiced by different people as a food security strategy from vulnerable households. but these part-time farms have had limited success in providing food/nutrition security, increasing incomes and improving well-be...

Surplus energy is principally stored in white adipose tissue (WAT) as triacylglycerol and mobilized via lipolysis through norepinephrine (NE) released from sympathetic nervous system terminals innervating WAT. We demonstrated that central melanocortin receptor agonism provokes differential sympathetic drives across WAT pads and interscapular brown adipose tissue (IBAT). Here we tested for diffe...

Introduction: Several reports show a relationship between health equity, and health status and longevity of individuals. In this study, effects of food deprivation, inequality and social instability were investigated on the formation of lipofuscin pigment in Balb/C mice by histopathological and biochemical methods. Methods: Thirty-six male mice were divided into 6 groups, then different kind...

based on both animal and human studies, inequality in food intake and social instability has adverse effects on the health of individuals and the community. however, it is not known whether social instability, food deprivation and food inequality affect neuronal death and premature aging in young animals. to address this question, the effects of these adverse situations, histopathological chang...

Introduction: The concentration of noradrenalin and corticosterone as the two nociception modulators change after fasting or stress situation. The aim of present study was to investigate the effect of food deprivation on formalin-induced nociceptive behaviours and plasma levels of noradrenalin and corticosterone in rats. Methods: Food was withdrawn 12, 24 and 48 h prior to performing the formal...

Twelve rats were food-deprived to 90% or 70% of their free-feeding weights. Food pellets were then delivered every 60 s (Fixed Time 60-s schedule), and the development of adjunctive drinking was measured by the water consumed and the number of licks. For "master" rats, each lick was followed by 10-s delays in food delivery. Yoked control rats received food at the same time as their master rats ...
