UCP1-independent thermogenesis
Biochemical Journal, 2020Obesity results from energy imbalance, when energy intake exceeds energy expenditure. Brown adipose tissue (BAT) drives non-shivering thermogenesis which represents a powerful mechanism of enhancing the energy expenditure side of the energy balance equation. The best understood thermogenic system in BAT that evolved to protect the body from hypothermia

Thermogenesis in decomposing carcasses
Forensic Science International, 2013It is of fundamental importance in forensic entomology that the factors controlling carcass temperatures during decomposition are thoroughly understood. The thermal environment to which fly larvae are exposed is the primary influence on their growth rate, and hence affects any estimate of minimum time since death using such specimens in homicide ...

Corticotropin and nonshivering thermogenesis
Experientia, 1977Chronic 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.

Central control of thermogenesis
Neuropharmacology, 2012In 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 ...

Fructose and dietary thermogenesis
The American Journal of Clinical Nutrition, 1993Ingestion of nutrients increases energy expenditure above basal metabolic rate. Thermogenesis of carbohydrate comprises two distinct components: an obligatory component, which corresponds to the energy cost of carbohydrate absorption, processing, and storage; and a facultative component, which appears to be related with a carbohydrate-induced ...

Postprandial Thermogenesis in Obesity
Clinical Science, 19811. 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.

Nutrient induced thermogenesis
Baillière's Clinical Endocrinology and Metabolism, 1997Although first described more than two centuries ago, the increase in energy expenditure associated with feeding (nutrient induced thermogenesis (NIT) is still incompletely understood. Although the magnitude of the response and the effect of varying the composition of the diet, route and rate of feeding is still the subject of controversy, the ...

Adaptive thermogenesis in hummingbirds
Journal of Experimental Biology, 2002SUMMARY 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.

FEVER AND BIOCHEMICAL THERMOGENESIS
Pediatrics, 1971Serum free fatty acid versus glycerol ratios were decreased in human newborn infants during pyrexia or cold injury, but remained practically unchanged in older infants and children. Decreased ratios in the newborn resulted exclusively from an increase in serum glycerol.

The regulation of body temperature is often conceptualized as a negative feedback control system complete with afferent limb, integrating area and effector limb. Most vertebrates regulate body temperature and these animals have been classified into two groups - ectotherms and endotherms.
