Core body temperature is one of the most tightly regulated parameters of human physiology. At any given time, body temperature differs from the expected value by no more than a few tenths of a degree. However, slight daily variations are due to circadian rhythm, and, in women, monthly variations are due to their menstrual cycle. Importantly, both anesthesia and surgery dramatically alter this d...

HEAT AND HYDRATION MAY NOT BE THE FIRST CONSIDERATIONS OF TOURNAMENT DIRECTORS, COACHES, AND ATHLETES, WHEN PREPARING FOR TENNIS. HOWEVER, HEALTH RISKS AND PERFORMANCE DECREMENTS ARE ASSOCIATED WITH BOTH. THE DEMANDS OF TENNIS, PARTICULARLY DURING MULTIDAY TOURNAMENTS, PREDISPOSE PLAYERS TO INCREASED CORE BODY TEMPERATURE AND LARGE FLUID LOSSES. THIS COMBINATION OF FACTORS CAN LEAD TO DECREASED...

We have compared deep body temperature (DBT) measured at the forehead with the core temperatures of the nasopharynx, oesophagus and rectum during the warming phase of cardiopulmonary bypass (CPB) (moderate hypothermia of 26.7-29.6 degrees C) in 12 patients. DBT was measured transcutaneously by an insulated thermistor probe that created an area of zero thermal flow between skin and subcutaneous ...

UNLABELLED Core hypothermia during the first hour after induction of general anesthesia results largely from an internal core-to-peripheral redistribution of body heat. This redistribution results from both central inhibition of tonic thermoregulatory vasoconstriction in the arteriovenous shunt and anesthetic-induced vasodilation. We therefore tested the hypothesis that acute administration of ...

BACKGROUND Shivering during regional anesthesia is a common complication and is related to a decrease in the patient's core body temperature. Previous studies have shown that acupuncture on specific acupoints can preserve core body temperature. The present study evaluated the effect of electroacupuncture in preventing the shivering caused by regional anesthesia. METHODS This prospective and r...

aggregation of pharmaceutical proteins reduces the efficiency and increases the cost of production. it can also lead to the reduced efficacy of drug or cause side effects on the patient’s body. investigating how to create them plays an important role to find agents that prevents the aggregation. this study was allocated for understanding the mechanism of formation of the reteplase protein using...

Body temperature in mammals is homeostatically regulated around a set point, which renders it independent of large variations in environmental temperature. Hypothalamic regions, including the preoptic area, act as thermoregulatory centers that receive temperature inputs from the core body through hypothalamic receptors and from the environment through skin receptors. Thermogenic and heatdissipa...

The large body of work demonstrating hyperthermic impairment of neuromuscular function has utilized maximal isometric contractions, but extrapolating these findings to whole-body exercise and submaximal, dynamic contractions may be problematic. We isolated and compared core and skin temperature influences on an isometric force task versus a position task requiring dynamic maintenance of joint a...
