Energy balance is a complex trait with relevance to the study of human obesity and maintenance energy requirements of livestock. The objective of this study was to identify, using unique mouse models, quantitative trait loci (QTL) influencing traits that contribute to variation in energy balance. Two F2 resource populations were created from lines of mice differing in heat loss measured by dire...

Intradialytic body temperature changes are governed by the thermal energy balance and heat capacity of the body. Resting energy expenditure is dissipated to the environment by evaporation, conduction and radiation. Homeostatic mechanisms maintain body temperature to an individual set-point by changing the radiative heat loss through vasoconstriction and vasodilatation. During haemodialysis, the...

During exercise in the heat, sweat output often exceeds water intake, resulting in a body water deficit (hypohydration) and electrolyte losses. Because daily water losses can be substantial, persons need to emphasize drinking during exercise as well as at meals. For persons consuming a normal diet, electrolyte supplementation is not warranted except perhaps during the first few days of heat exp...

for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day -1 . Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h -1 , and fluid loss at this rate si...

The present study involves the examination of explanation of Koro illness as perceived by the patients during a Koro epidemic in the North Bengal region of West Bengal state, India. Using both quantitative and qualitative method of data collection several ethnomedical explanatory concepts like increased body heat, supernatural, sexual, physical strain; fever and fear were elicited as the emic f...

The effect of body fatness on the fasting heat production and energetic efficiency of adult sheep was studied. Energy balance and heat production were determined in adult wether sheep at three fatness levels given a diet of grass hay and maize at four feeding levels, including fasting, in open-circuit respiration chambers. The sheep weighted approximately 60 kg at the start and were fed over a ...

PURPOSE Assessment of post-exercise changes in hydration with bioimpedance (BI) is complicated by physiological adaptations that affect resistance (R) and reactance (Xc) values. This study investigated exercise-induced changes in R and Xc, independently and in bioelectrical impedance vector analysis, when factors such as increased skin temperature and blood flow and surface electrolyte accumula...

Metallized plastic sheeting (m.p.s.) was used in 14 neurosurgical patients and changes in body heat content during surgery compared with those of 14 control patients. All patients, except three in the study group and one in the control group, lost heat by the end of the operation. There was, however, a statistically significant reduction in heat loss in the patients wrapped in m.p.s. Measuremen...

Fever defined Although fever has often been defined as any elevation in body temperature, this definition would result in considerable confusion between true fever and hyperthermia. In fever, as a result of the elevated thermoregulatory ‘set-point’, a person’s heat production increases, while at the same time heat loss decreases. Snell & Atkins (1968) defined four categories of body temperature...
