Background: We deciphered thermoregulatory activities of exotic breeds of rabbit in the event of least thermal discomfort in Ibadan, Nigeria. This investigation was carried out between July and August during the least temperature-humidity index (THI). Twenty bucks and 14 doe per breed, housed individually and randomly assigned to experimental units in a completely randomized design, were used f...

An increase in variation in the 24 h pattern of body temperature (heterothermy) in mammals can be induced by energy and water deficits. Since performance traits such as growth and reproduction also are impacted by energy and water balance, we investigated whether the characteristics of the body temperature rhythm provide an indication of the reproductive success of an individual. We show that t...

Previous studies have inferred a relationship between core temperature and sleep disruption from manipulations of core temperature such as heating prior to sleep or administration of hyperthermic substances. To examine the relationship more directly, this study aimed to produce a direct increase in core temperature during the sleep period. Following an adaptation night, 16 subjects underwent co...

A mathematical model of the human eye based on the bioheat transfer equation is developed. The intraocular temperature distribution is calculated using the Galerkin finite element method. A difficulty associated with the development of an accurate model of the human eye is the lack of reliable biological data available on the constants and parameters that are used in the model. These parameters...

BACKGROUND Infants and children cool quickly because their surface area (and therefore heat loss) is large compared with their metabolic rate, which is mostly a function of body mass. Rewarming rate is a function of cutaneous heat transfer plus metabolic heat production divided by body mass. Therefore, the authors tested the hypothesis that the rate of forced-air rewarming is inversely related ...

abstract background: in 1958, silverman demonstrated that maintenance ofbody temperature reduces mortality in low birth weight infants. from the early 1990s it was already recognized that adequate environmental warmth was essential in the case of newborns. however, neonatal hypothermia continues to be a significant issue in developing countries. methods: in order to describe the incidence and s...

background & aim: the effect of the anesthetic substance given to the mother during cesarean section, and the pain experienced by the mother after the intervention practiced on the mother during cesarean section delay the mother-infant interaction and the initiation breastfeeding time. this study has been conducted to determine the effects of breastfeeding counseling given to the mothers that g...

Alzheimer's disease (AD) is characterised, not only by cognitive deficits and neuropathological changes, but also by several non-cognitive behavioural symptoms that can lead to a poorer quality of life. Circadian disturbances in core body temperature and physical activity are reported in AD patients, although the cause and consequences of these changes are unknown. We therefore characterised ci...
