... in response to cold and food deprivation. Acute cooling (1°C day −1 ) from 14°C to 2°C had no effect on food consumption but reduced activity by 77%. We then assessed metabolic performance and demand over 90 days with exposure to warm (8°C) or cold winter (2°C) temperatures while fish were fed or starved...

...Etsuro Ito; Miki Yamagishi; Dai Hatakeyama; Takayuki Watanabe; Yutaka Fujito; Varvara Dyakonova; Ken Lukowiak ABSTRACT Food deprivation for 1 day in the pond snail Lymnaea stagnalis before aversive classical conditioning results in optimal conditioned taste aversion (CTA) and long-term memory (LTM...

...Shaun S. Killen; Stefano Marras; David J. McKenzie While many ectothermic species can withstand prolonged fasting without mortality, food deprivation may have sublethal effects of ecological importance, including reductions in locomotor ability. Little is known about how such changes in performance...

... are not well described. To assess the effects of prolonged food deprivation on systemic and local RAS, and their potential contribution to TNF-α as they relate to an IR condition, the mRNA expressions of adipose and muscle RAS components and immuno-relevant molecules were measured along with plasma RAS...

... and high food availability conditions. Food deprivation generates oxidative stress mainly due to a depletion of organ antioxidant stores and an increase in free radical production especially in the liver ( Pascuala et al., 2003 ; Robinson et al., 1997 ). Using an experimental approach, we address two...

... segment of the nephron, moderate in the collecting duct and absent in the proximal segment. To investigate a potential role for occludin in the maintenance of the hydromineral balance of fishes, we subjected goldfish to 1, 2 and 4 weeks of food deprivation, and then examined the endpoints of hydromineral...

...Shannon P. Reidy; Jean-Michel Weber SUMMARY The energy metabolism of hibernators has not been characterized for normothermic fasting, and our goal was to quantify oxidative fuel selection of non-hibernating woodchucks Marmota monax during prolonged food deprivation. Indirect calorimetry...

... with food deprivation and exercise-training studies in that fish become less active and are often overfed, and cardiac morphology certainly changes in salmonids raised for aquaculture. The normally distinct pyramidal structure of the ventricle( Fig. 2A ) becomes more rounded( Fig. 2B,D ), resembling...

... is not used by the Virginia opossum to cope with food deprivation. However, a rapid exhaustion of limited carbohydrate reserves is prevented through a sixfold reduction in the percentage contribution of carbohydrates to total energy expenditure made possible by an increase in lipid utilization. No protein...

... that feeding behavior varies in a manner dependent on feeding regime (food-deprived or ad-libitum -fed) and nutritional state. Fed flies that are subsequently food-deprived become increasingly more responsive to food stimuli over time and, when offered 1% agar diets containing different concentrations...
