Journal ArticleDOI
TL;DR: Recent studies have shown that insulin levels in fish are similar to or often higher than those observed in mammals, thus indicating that fish are not diabetic as previously thought.

TL;DR: Compared cathepsin B, H and L activities were compared in hindlimb muscles and liver at various phases of starvation in thyroidectomized and sham-operated rats, suggesting that different mechanisms modulate cat hepsin expression in skeletal muscle and liver.

TL;DR: It appears that a factor related to spontaneous reduction in food intake enables ground squirrels to achieve the total sparing of protein that eludes dieting humans on comparably low caloric intakes.
Abstract: During seasonal cycles in ground squirrels, as in many other species, there are periods of spontaneous loss of appetite, very low calorie intake and a 30% loss in body mass. Measurements of nitrogen balance during early and later stages of the mass loss phase of the cycle (-1.2 +/- 6.7 and +13.1 +/- 8.8 mg/24 h, respectively) showed a total sparing of protein, indicating a selective use of fat. However, when no food at all was available, nitrogen balance was negative (-45 +/- 5 mg/24 h). Provided that they have access to some food, ground squirrels are therefore able to compensate for any protein utilization, while at the same time selectively losing large amounts of fat. It appears that a factor related to spontaneous reduction in food intake enables these animals to achieve the total sparing of protein that eludes dieting humans on comparably low caloric intakes.
