The aim of the paper was to follow up major physiological reactions, provoked by heat stress during dry and wet sauna baths. A physical strain index and subjective estimation of heat comfort of subjects who had not taken sauna baths before was also evaluated. Ten healthy males aged 25-28 underwent a dry sauna bath and then after a one-month break they underwent a steam sauna bath. Each time, th...

background: the phase change materials (pcms) have the appropriate properties for controlling heat strain. one of the well-known pcms is paraffin. this study aimed to design the cooling vest from the cheap commercial paraffin compound and evaluation of its effectiveness under laboratory hot conditions. methods: the cooling vest was made of the polyester fabric and it had 17 aluminum packs. the ...

original article   introduction: exposure to heat is one of the workplace risk factors, which may lead to thermal strain, such as rising heart rate and body temperature. to have the best association between a heat stress indices and physiological parameters have always been a major concern for those studying the subject. this study aims to compare the association of two heat stress indices with...

A physiological strain index (PSI), based on rectal temperature (Tre) and heart rate (HR), was recently suggested for evaluating heat stress. The purpose of this study was to evaluate the PSI for different combinations of hydration level and exercise intensity. This index was applied to two databases. The first database was obtained from eight endurance-trained men dehydrated to four different ...

For the military and civilian first responders heat injury is a very real concern. Several real-time physiological monitoring systems exist that can utilize heat strain indexes [e.g. physiological strain index (PSI)] and provide alerts to medical personnel. However, these systems depend on core temperature measurement using ingested pill thermometers which can suffer inaccuracies from ingested ...

background: heat stress is one of the agents in the work environment that can create numerous problems for workers. the objective of this research is to study heat stress control in the foundry platform of a steel plant in tehran. methods: in this experimental study, controlling plans were demonstrated for the work conditions improvement in one of steel plant's foundry platforms. for controllin...

BACKGROUND Melioidosis is an important cause of morbidity and mortality in East Asia. Recurrent melioidosis occurs in around 10% of patients following treatment either because of relapse with the same strain or re-infection with a new strain of Burkholderia pseudomallei. Distinguishing between the two is important but requires bacterial genotyping. The aim of this study was to develop a simple ...

This article describes the development, application, and validation of a scoring index for assessment of clinical signs in cats with flea allergy dermatitis (FAD). The Scoring Index for Clinical Signs of FAD was based on the evaluation and scoring of five signs over five anatomic areas, which is similar to the psoriasis area and severity index (PASI), a commonly used scoring method in human der...
