Central control of thermogenesis

Neuropharmacology, 2012
In mammals and birds, conservation of body heat at around 37 °C is vital to life. Thermogenesis is the production of this heat which can be obligatory, as in basal metabolic rate, or it can be facultative such as the response to cold. A complex regulatory system has evolved which senses environmental or core temperature and integrates this information ...

Growth, thermogenesis, and hyperphagia

The American Journal of Clinical Nutrition, 1990
Resting metabolic rate is demonstrated to be a function of fat-free mass and a growth variable related to food-energy-input imbalance rate. By use of obligatory energy expenditure terms, the two-reservoir energy model applied to hyperphagia shows that growth of the fat-free mass is rapid whereas that of the fat store is slow and that the growth of both

Corticotropin and nonshivering thermogenesis

Experientia, 1977
Chronic treatment with corticotropin led to reduced calorigenic effect of norepinephrine in cold acclimatized rats, but potentiated its effect in controls. This inhibitory effect was not due to the observed decrease in corticosterone plasma level, as it was shown by metopirone administration.

Reduced thermogenesis in obesity

Nature, 1979
IT is often claimed that there are obese patients who find it difficult to maintain a normal body weight because they have such low energy requirements that even normal intakes of energy result in weight gain and obesity. Studies of both children1 and adults2 show that there can be a twofold difference in energy intake between individuals despite ...

Adaptive thermogenesis in hummingbirds

Journal of Experimental Biology, 2002
SUMMARY The occurrence of non-shivering thermogenesis in birds has long been a controversial issue. Although birds are endothermic vertebrates, sharing with mammals (placental mammals and marsupials) a common ancestor, they do not possess brown adipose tissue or a similar type of tissue, unlike their mammalian counterparts.

Diet-induced thermogenesis

Pharmacology & Therapeutics, 1982
Mammals must take in large quantities of food, sometimes equivalent to their own body weight each day, in order to meet the energy requirements of processes such as maintenance, growth, activity, thermoregulation, pregnancy, and lactation. It is therefore remarkable to observe that in adults of most species energy intake is equal to expenditure, and ...

Mitochondrial thermogenesis and obesity

Current Opinion in Clinical Nutrition and Metabolic Care, 2007
Thermogenesis is activated at the expense of carbon molecules. Mitochondria play a dominant role in oxidation and parallel heat production since the recovery of oxidation energy is less than perfect. Recent data of mitochondriogenesis and mitochondrial thermogenesis may boost research into certain aspects of obesity.Recent studies have outlined the ...

Studies in Microbial Thermogenesis

Science, 1927
An apparatus for the study of the "spontaneous" heat production in stored organic materials has been described. Experiments with commercial cornmeal and cracked yellow field corn have shown that temperatures above 60°C. can readily be produced under suitable conditions of moisture content, oxygen supply and insulation, and that marked heating does not ...

Postprandial Thermogenesis in Obesity

Clinical Science, 1981
1. The thermogenic response and changes in plasma substrates and hormones were tested after a liquid meal in lean, obese and formerly obese women. 2. Subjects with a family history of obesity tested either while obese or after slimming to a normal weight had a thermogenic response, which was only half that of the lean group.
