A recent paper by Belle et al. (J. Mol. Evol. 55 (2002) 356) reported an analysis of mean GC(3) (the GC level of third codon positions) and standard deviations of GC(3) of vertebrate genomes as related to body temperature, and concluded that "the thermal stability hypothesis does not appear to explain the general patterns of composition", apparently contradicting a previous working hypothesis f...

BACKGROUND Growing evidence indicates that elevated body temperature after stroke is associated with unfavorable outcome. The aim of the current study was to investigate which factors predict temperature elevation within 48 h of stroke onset. Specifically, we hypothesized that temperature elevation would be associated with stroke symptom severity and that hemorrhagic stroke would cause a more p...

Dairy farmers and veterinarians have used body temperatures, most commonly rectal temperatures, to detect and manage febrile disease and changes in the state of cows (estrus and onset of calving) for many years. Mastitis, pneumonia, metritis, lameness, estrus, onset of parturition, heat stress, and subacute ruminal acidosis (SARA) are among the physiological conditions potentially correlated wi...

The homeostatic control of body temperature is essential for survival in mammals and is known to be regulated in part by temperature-sensitive neurons in the hypothalamus. However, the specific neural pathways and corresponding neural populations have not been fully elucidated. To identify these pathways, we used cFos staining to identify neurons that are activated by a thermal challenge and fo...

This article describes an evidence-based method for measurement of body temperature consistent with The Principles of Clinical Examination [1]. Temperature measurement at oral, aural, rectal and axillary sites is addressed, and measurement technique, accuracy and precision, and the normal ranges are discussed. We recommend a method for the measurement of body temperature based on the best evide...

BACKGROUND Human obesity is associated with increased heat production; however, subcutaneous adipose tissue provides an insulating layer that impedes heat loss. To maintain normothermia, therefore, obese individuals must increase their heat dissipation. OBJECTIVE The objective was to test the hypothesis that temperature in a heat-dissipating region of the hand is elevated in obese adults. D...
