Animals need to maintain body temperature to prevent CELL damage caused by overheating or freezing: heat changes the structure of PROTEINS and kills neurons—even the high temperatures (HYPERPYREXIA) associated with FEVER can sometimes do this,...

The human body is able to actively regulate its internal temperature somewhere between 98°F (36.6°C) and 100°F (37.7°C) in spite of various forces that act to cool off the body. These mechanisms operate through a control region of the...

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when temperature surrounding is very different. This process is one aspect of homeostasis: a dynamic state of stability between an animal's...

THE CIRCUIT IN Figure 1 is a proportional thermoregulator in which the switching of the triac occurs when the mains voltage crosses the zero level. As a result, the circuit generates no RFI. The circuit can easily achieve linear regulation and perfect isolation...

Abstract: Fever is common in postoperative neurosurgical patients. When fever is present, thermoregulatory responses regulate body temperature within a range that appears to have an upper limit. Endogenous substances, such as arginine vasopressin (AVP), modulate the thermoregulatory response during fever and are referred...
