“…Finally, in contrast to the controlled intervention of a hyperinsulinemic euglycemic clamp, postprandial BAT metabolism and energy expenditure are under the control of a complicated physiologic response to the meal. Multiple mechanisms may affect energy expenditure, such as diet-induced thermogenesis and the thermic effect of food itself (e.g., metabolic, endocrine, cardiovascular, sympathetic, and gut responses) (10). Another explanation for the lower glucose uptake in the postprandial state might be a relatively higher contribution of lipid oxidation to total BAT energy expenditure.…”

Emotion is one of the central topics in animal studies and is likely to attract attention substantially in the coming years. Recent studies have developed a thermo-imaging technique to measure the facial skin temperature in the studies of emotion in humans and macaques. Here we established the procedures and techniques needed to apply the same technique to great apes. We conducted two experiments respectively in the two established research facilities in Germany and Japan. Total twelve chimpanzees were tested in three conditions in which they were presented respectively with the playback sounds (Exp. 1) or the videos (Exp.2) of fighting conspecifics, control sounds/videos (allospecific display call: Exp. 1; resting conspecifics: Exp.2), and no sound/image.Behavioral, hormonal (salivary cortisol) and heart-rate responses were simultaneously recorded. The nasal temperature of chimpanzees linearly dropped up to 1.5 degree in two minutes, and recovered to the baseline in two minutes, in the experimental but not control conditions. We found the related changes in excitement behavior and heart-rate variability, but not in salivary cortisol, indicating that overall responses were involved with the activities of sympathetic nervous system but not with the measureable activities of the hypothalamus-pituitary-adrenal (HPA) axis. The influence of general activity (walking, eating) was not negligible but controllable in experiments. We propose several techniques to control those confounding factors. Overall, thermo-imaging is a promising technique that should be added to the traditional physiological and behavioral measures in primatology and comparative psychology.

“…In short, TCA cycle flux is measured combining information from 31 P-MRS and NIRS to assess ATP production and oxygen consumption, respectively [18,19 ]. A second method is based on the combination of 13 C NMR (or MRS) and 31 P NMR (or MRS) [18]. This second approach is based on the 13 C NMR-based assessment of citric acid cycle activity and the 31 P NMR-based assessment of ATP synthesis.…”

“…Furthermore, the contribution of proton leaks to resting metabolic rate can be as large as 20-50% [12], demonstrating the large potential of skeletal muscle to increase oxygen uptake. For example, the contribution of the skeletal muscle to diet-induced adaptive thermogenesis ranges between 35 and 67% [13]. In addition, up to 50% of adrenalin-induced thermogenesis was demonstrated to originate at the skeletal muscle level [14].…”

IntroductionIn this review we set out to give an overview of the latest developments in the field of increasing whole-body energy expenditure via adaptive thermogenesis. In particular, we focus on the contribution of skeletal muscle mitochondrial uncoupling to whole-body energy expenditure and adaptive thermogenesis. In addition, we review the latest developments regarding the application of increasing adaptive thermogenesis to fight the obesity epidemic and the possibilities to achieve this goal by modulation of skeletal muscle mitochondrial uncoupling.In the modern Western society, the prevalence of obesity and obesity-related disorders are rising. The development of obesity is the result of a prolonged imbalance between energy intake and energy expenditure, and classically focus has been on reducing energy intake to correct this imbalance. However, although successful in the short term, the success rate of reducing energy intake in the long term is notoriously poor in humans, possibly due to the decrease in resting metabolic rate and exerciserelated energy expenditure as well as by promoting an unfavourable energy intake pattern [1 ,2 ,3 ]. The reduction in metabolic rate could be a risk factor for weight regain in itself, although the contribution of energy intake and expenditure to weight gain are still under debate [4 ]. Attempts to improve energy balance by exercise programmes have generated unclear results. Structured physical activity has been reported to increase total energy expenditure rates [5] but was found not to affect energy expenditure in another study [6]. Interestingly, Turner et al. [7 ] demonstrated that a 6-month progressive exercise programme does result in weight loss but the absolute reduction is less than expected due to an increase in energy intake. This stresses the importance to measure and report both sides of the energy balance. Thus, despite the obvious social and health benefits, the limited potency for physical exercise programmes to increase total energy expenditure may be due to the fact that the caloric cost per Purpose of review The prevalence of obesity is still increasing, despite obesity treatment strategies that aim at reducing energy intake. In addition to this, exercise programmes designed to increase energy expenditure have only a low efficiency and have generated mixed results. Therefore, strategies based on increasing energy expenditure via nonexercise means are currently under investigation. One novel strategy is the modulation of adaptive thermogenesis. Recent findings Among others, adaptive thermogenesis can be modulated by changing dietary composition, treatment with hormone mimetics as well as by cold exposure. In humans, a large part of the adaptive thermogenic response is, in addition to a putative role of brown adipose tissue, determined by the skeletal muscle mass via the process of mitochondrial uncoupling. Here, we describe the molecular processes involved in mitochondrial uncoupling, state-of-the-art techniques to measure mitochondrial uncoupling ...
