The purpose of this study was to develop a body characteristic index (BCI) based on the distribution of maximal oxygen uptake per body mass (VO2max/mass), body surface area per body mass (BSA/mass), and percentage of body fat (Fat%) to evaluate the relative level of individual physiological responses to heat strain in a group of workers. BCI was based upon the data obtained from 10 males and 10...

BACKGROUND/AIM In military services, emergency situations when soldiers are exposed to a combination of nuclear, biological and chemical (NBC) contamination combined with heat stress, are frequent and complex. In these specific conditions, usage of personal body cooling systems may be effective in reducing heat stress. The present study was conducted in order to evaluate the efficiency of four ...

(MARC) near clay center, NE during the summer of 2014. The objective of this trial was to measure the effects of supplementing zilpaterol hydrochloride (ZH) for the final 21 days of the finishing period, and shade, on performance, body temperature, respiration rate, and mobility of finishing beef steers. Feeding ZH increased hot carcass weight, dressing percent, longissimus muscle area, and red...

Thermal comfort under non-steady-state conditions primarily deals with rapid environmental transients and significant alterations of the meteorological conditions, activity, or clothing pattern within the time scale of some minutes. In such cases, thermal history plays an important role in respect to time, and thus, a dynamic approach is appropriate. The present study aims to investigate the dy...

ABSRACT The present experiment was designed to evaluate the effect of different protein and energy levels on broilers performance under hot climatic conditions. A total of three hundred Ross-308 chicks were selected on basis of uniform starting live bodyweight (45g/chick) proximately. Chicks were randomly divided into three treatments with five groups of 20 chicks per pen. Diets were formulated...

Castle, Paul C., Adam L. Macdonald, Andrew Philp, Anthony Webborn, Peter W. Watt, and Neil S. Maxwell. Precooling leg muscle improves intermittent sprint exercise performance in hot, humid conditions. J Appl Physiol 100: 1377–1384, 2006. First published December 8, 2005; doi:10.1152/japplphysiol.00822.2005.—We used three techniques of precooling to test the hypothesis that heat strain would be ...

Clerodendron colebrookianum Walp., (Fam: Verbenaceae) locally known is "NEFAFU" is widely used for curing various diseases. Here some pharmacological properties of this plant were studied using rat & mice of either sex. Methanol extract (MLE) of various concentrations (50, 100, 200 mg/kg of body wt) were tested on animals. Carrageenin induced rat paw oedema model with three hours for oedema for...

this study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (bbb) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. methods: each age group of rats was sub div...

We explicitly quantified spatial and temporal patterns in the body temperature of an ecologically important species of intertidal invertebrate, the musselMytilus californianus, along the majority of its latitudinal range from Washington to southern California, USA. Using long-term (five years), high-frequency temperature records recorded at multiple sites, we tested the hypothesis that local ‘‘...
