OBJECTIVE Heat illnesses contribute to significant morbidity and occasional mortality in athletic populations. Sunburn increases the risk of various skin carcinomas. This report provides an overview of the etiology, symptomatology, risk identification, prevention, and treatment for heat related illnesses and sunburn. CLINICAL FEATURES Four cases are presented to illustrate the diagnosis and i...

Two hundred and fifty male 1-day-old broiler chicks (Ross 308) were used to investigate the effects of dietary supplementation of turmeric and cinnamon powders on meat quality and lipid peroxidation of broilers under heat stress condition. The five treatment groups were control (recommended temperature for Ross 308), heat stressed (32 ± 1 ˚C from 9:00 AM to 5:00 PM during finisher period) and h...

The purpose of this study was to assess the effect of mild heat and heat preconditioning on the uptake and permeability of a P-glycoprotein (P-gp) substrate, rhodamine 123 (R123), in a cell culture model of the blood-brain barrier (BBB). An immediate goal was to determine whether prior mild heat treatment could render brain microvessel endothelial cells more resistant to future heat stress and ...

High-pressure CO2 treatment has been studied as a promising method for inactivating bacterial spores. In the present study, we compared this method with other sterilization techniques, including heat and pressure treatment. Spores of Bacillus coagulans, Bacillus subtilis, Bacillus cereus, Bacillus licheniformis, and Geobacillus stearothermophilus were subjected to CO2 treatment at 30 MPa and 35...

The effect of pre-heat treatments, followed by a hot forging process, on the microstructure and strength of Co–Cr–Mo alloys was investigated. Four pre-heat treatments were conducted at 1170, 1200, 1230 and 1260 C for three different time condition: 2, 6 and 15 h and then water cooled to room temperature. Tensile tests and XRD analyses were carried out on both as-cast alloy and heat-treated allo...

Heat stroke in athletes is entirely preventable. Exertional heat illness is generally the result of increased heat production and impaired dissipation of heat. It should be treated aggressively to avoid life-threatening complications. The continuum of heat illness includes mild disease (heat edema, heat rash, heat cramps, heat syncope), heat exhaustion, and the most severe form, potentially lif...
