Beyond the classic thermoneutral zone
The thermoneutral zone is defined as the range of ambient temperatures where the body can maintain its core temperature solely through regulating dry heat loss, i.e., skin blood flow. A living body can only maintain its core temperature when heat production and heat loss are balanced. That means that heat transport from body core to skin must equal heat transport from skin to the environment. T...
متن کاملOrgan-specific changes in norepinephrine turnover against various stress conditions in thermoneutral mice.
The effects of three stressors of different categories, namely cold exposure, immobilization, and lipopolysaccharide (LPS) treatment, on sympathetic nerve activity were examined by assessing its biochemical index norepinephrine (NE) turnover in peripheral organs of C57BL/6 mice. NE turnover was assessed by measuring the decrease in the organ NE concentration 3 h after inhibition of catecholamin...
متن کاملLeptin effect in ob/ob mice under thermoneutral conditions depends not necessarily on central satiation.
Energy expenditure in ob/ob mice kept at thermoneutrality was quantified from food intake and body composition of mice treated with leptin over 15 and 75 days, respectively. Energy expenditure in response to 15 days of treatment with leptin was twice as high as under pair-feeding conditions, indicating extensive breakdown of adipose tissue independent of a centrally mediated satiation. Leptin-i...
متن کاملTumour targeting: Nanoantennas heat up.
manipulations can be conducted at any desired time during an experiment. This novel approach to hydrogel design should be particularly appealing for fields such as developmental biology, stem-cell biology or tumour-cell biology, in which the role of the microenvironment in controlling cell function is particularly important and is still relatively poorly understood. With these novel ECM models ...
متن کاملThe thermoneutral zone: implications for metabolic studies.
A thermoneutral environment is important for many human physiological studies. The thermoneutral zone (TNZ) is defined as the range of ambient temperatures without regulatory changes in metabolic heat production or evaporative heat loss. Many factors influence the thermoneutral zone, such as body composition, clothing, energy expenditure, age and gender. These factors have the potential to intr...
