Body temperature regulation in the rat
Journal of Thermal Biology, 2000In loosely-restrained adult conscious rats exposed to stepwise changes in ambient temperature (T(a)) from 25 to 5 degrees C or from 20 to 35 degrees C, we have recorded body and tail temperatures, metabolic rate (VO(2)), shivering and ventilation (V).

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 ...

The Regulation of Body Temperature During Fever
Archives of Environmental Health: An International Journal, 1965Abstract : Fever in man was studied calorimetrically to determine, first, the heat flows which cause changes in body temperature and, second, the physiological regulations which directly control these flows. Seventeen reactions induced by typhoid vaccine were observed in environments ranging in ambient temperature from 27 to 43 C.

BODY TEMPERATURE REGULATION AND THERMONEUTRALITY IN RATS
Quarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1977Various concepts of thermoneutrality were considered for a proposed study of the role of hypothalamic amines in temperature regulation of rats. The classic definition, the ambient temperature over which metabolic rate is minimum and constant, gave a range of approximately 28 to 32°C.

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.

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 ...

The Design of an Automatic Body Temperature Regulator
2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019This paper proposes a design of an automatic body temperature regulator (ABTR) with a bidirectional buck-boost converter. This system can detect the movement state of human body and the cooling mechanism will activate to lower the body temperature automatically.

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

Regulation of Body Temperature
1976Birds, like mammals, are “homeotherms,” which means that they maintain a relatively constant deep-body temperature. Birds are also “endotherms,” a term indicating that they are able to increase their body temperature by generating a considerable amount of heat within their tissues instead of relying on heat gained directly from their surroundings ...

Experiments examining the effects of central injections of E-series prostaglandins (PGE) on body temperature have only been done in the light part of a light-dark cycle. The present experiments examined the characteristics of fevers in rats after intraventricular PGE2 injections in both light and dark in a 12:12 h photoperiod. In the light, the change
