Body temperature and its regulation
Anaesthesia & Intensive Care Medicine, 2008Abstract Body temperature is regulated to a ‘set point’ that is determined by the hypothalamus. The precise value of this set point has a circadian rhythm and is also affected (increased) by trauma and sepsis. In thermoregulatory terms, the body is thought of as a ‘central’ compartment containing all the heat-producing viscera, contained in a cooler ‘

Regulation of body temperature by the bluefin tuna
Comparative Biochemistry and Physiology, 1969Abstract Bluefin tuna (Thunnus thynnus Linnaeus) can control the temperature of their bodies (25–30°C) so that the warmest portion of the muscle mass varies only 5°C over a 10°C–30°C range of water temperature.

Body temperature regulation and anesthesia
2018General anesthesia is the induction and maintenance of a state of unconsciousness with the absence of pain sensation. General anesthesia is accomplished by the administration of a combination of inhaled anesthetic gases and intravenous drugs. These medications eliminate behavioral thermoregulatory compensations, leaving only autonomic defenses to ...

Regulation of Body Temperature
1992Homeothermy is defined by the Thermal Physiology Commission of the International Union of Physiological Sciences [35] as a pattern of temperature regulation in which cyclic variation in core temperature is maintained within arbitrary limits of ±2°C despite much larger variations in ambient temperature.

Body temperature and its regulation
Anaesthesia & Intensive Care Medicine, 2005Abstract Humans must maintain deep-body (core) temperature within narrow limits, despite large fluctuations in ambient temperature and metabolic heat production. Core temperature homeostasis is facilitated by behavioural strategies and physiological effector responses, which influence the factors that add and subtract body heat.

Body temperature regulation and drugs of abuse
2018Phenethylamine-induced hyperthermia can occur following exposure to several different types of illicit stimulants, such as amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine ("Molly"), synthetic cathinones ("bath salts"), and N-methoxybenyl ("NBOMe"), to name a few. Peripheral norepinephrine release mediated by these sympathomimetic agents

Adenosine and the Regulation of Metabolism and Body Temperature
2011Adenosine levels are increased under conditions of energy deprivation, both because intracellular energy stores are reduced and because ATP is released. The adenosine thus formed can serve to influence energy homeostasis in a number of different ways, besides alterations in blood supply and cellular work (including contraction, maintenance of membrane ...

Body Weight and the Energetics of Temperature Regulation
Journal of Experimental Biology, 1970ABSTRACT The interactions of basal rate of metabolism, thermal conductance, body temperature, lower limit of thermoneutrality, and body weight in mammals are compatible with Newton’s law of cooling. A small body weight will normally reduce the level and preciseness of body temperature, but a high basal rate of metabolism or a low thermal

Catecholamines and the Regulation of Body Temperature
1980It is clear now that the two principal components of an animal’s temperature regulating capacity — central and peripheral — utilize catecholaminergic mechanisms. What is biologically so fascinating is the entirely different way in which a given catecholamine acts. On the one hand, central noradrenergic neurons are involved in the complicated activation
