A system has been established for continuous recording of rectal and body surface temperatures in conscious, chair-restrained rhesus macaques. Diurnal changes in rectal temperature and body surface temperatures of head, back, abdomen, and inner thigh were recorded for 24 hours under conditions of intermittent or constant light. When lights were on for 8 hours (0800 to 1600 hours) and off for 16...

Background: The daily rhythm of body temperature is an important process to be studied not only to advance knowledge on the temporal variability of thermal homeostasis but also has a means to facilitate the study of biological rhythmicity in general. The aim of the present study was to study the daily rhythm of rectal temperature and the changes in the serum levels of mitochondrial uncoupling p...

OBJECTIVE To compare a dose of oral and rectal acetaminophen and to evaluate acceptability of rectal acetaminophen, since oral and rectal acetaminophen is widely used as an antipyretic agent in febrile children and the comparative effectiveness of these two preparations is not well established. METHODS In this prospective parallel group designed study, 60 children who presented to the emergen...

OBJECTIVES There are several recommendations on the prevention of hypothermia during snow shoveling. However, there seemed to be insufficient evidence supporting these recommendations because they are not based on data from actual snow shoveling research. The purpose of this study was to investigate changes in brain temperature (tympanic temperature) and visceral temperature (rectal temperature...

The methanol extract of Ichnocarpus frutescens R.Br. root (MEIF) was evaluated for its anti-pyretic potential on normal body temperature and yeast-induced pyrexia in albino rats. Yeast suspension (10 ml/kg body wt.) increased rectal temperature 19 h after subcutaneous injection. The MEIF, at doses of 100, 200, and 300 mg/kg body wt., p.o., produced significant reduction in normal body...

results twelve original studies fulfilled the inclusion criteria. the current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. conclusions there are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and ou...

AIMS To test the hypothesis that external radiant heating might lead to significant fluctuations in superficial and core head temperatures in newborn infants. METHODS In an observation group of 14 term infants nursed under a radiant heater, servo-controlled to the abdominal skin, changes in rectal, core head, and scalp temperatures with heater activation were examined. In a further interventi...

Genetic selection for body temperature during heat stress might be a useful approach to reduce the magnitude of heat stress effects on production and reproduction. Objectives of the study were to estimate the genetic parameters of rectal temperature (RT) in dairy cows in freestall barns under heat stress conditions and to determine the genetic and phenotypic correlations of rectal temperature w...

BACKGROUND Temporal artery (TA) thermometry has come as one of the new methods for temperature measurement, especially in children in whom accurate temperature monitoring can save lives. The device which is convenient and simple to use is yet to gain popularity in several parts of the world, as there are conflicting reports of its accuracy. This study compares the accuracy of the TA thermometry...

A study was performed to evaluate differences in thermoregulatory ability of 2 Bos taurus breeds with known differences in heat tolerance. Nine Angus (AG; 304 +/- 7 kg of BW) and 9 Romosinuano (RO; 285 +/- 7.5 kg of BW) steers were transported to the Brody Environmental Center at the University of Missouri. Steers were housed for 18 d at thermoneutrality (TN; 21 degrees C) before initiation of ...
