Annual Review of Physiology, 1994
Skeletal muscles are most often examined at the cellular level in relationship to their primary role in force generation. Throughout the animal kingdom, regardless of phylogeny, muscle generates heat. Exercise, shivering, and nonshivering thermogenesis provide excess heat in muscle that affords adaptive significance to a wide variety of organisms ...

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, 2007Thermogenesis 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 ...

Brain Research Bulletin, 1984
Nonshivering thermogenesis was originally defined as a cold-induced increase in heat production not associated with the muscle activity of shivering. Recent research shows it to be a metabolic process located primarily in brown adipose tissue and controlled by the activity of the sympathetic nervous supply of this tissue.

Annual Review of Physiology, 1976
The principal conclusion presented in this review is that no single mechanism underlies any of the examples of basal or altered cellular thermogenesis. Both increased Na+ pump operation and uncoupling may occur to a greater or lesser extent, as may other heat-producing mechanisms.

Reduced thermogenesis in obesity [PDF]
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 ...

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 ...

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 ...
