chemotherapeutic agents used in patients with cancer cause to generate the enormous amounts of free radicals associated with cell injury. in this study we assess the effects of chemotherapy regimen on oxidant/antioxidant status in patients with acute myeloid leukemia (aml). 38 newly diagnosed patients with acute myeloid leukemia were recruited in this study. all patients received cytarabine and...

objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali).   materials a...

heat stress effects on physical and mental health of workers and decreases human function. asphalt workers are both exposed to the heat of their working process and to the sun heat. this study aimed at evaluating thermal stress and its following function fall and the effect of asphalt work on the degree of heat stress and asphalt workers’ physiological parameters. the present study was done at ...

climate changes due to global warming is affecting world agriculture adversely. heat stress due to global warming has turned to one of the most important factors reducing quantity and quality of plants production such as tomato. despite of wide cultivation of tomato and high temperature effects on its production, unfortunately; research in this area is scarce. this study was conducted to invest...

abstract background: heat is one of the most important of harmful agents in many working environments such as bakeries that can cause prevalence of diseases related to heat and falling of efficiency. aim of this study was exposure evaluation of isfahan bakers to heat stresses in their working environment through evaluation of relationship among wet bulb globe temperature index (wbgt) , oral tem...

Heat stroke is a life-threatening illness, and the disease spectrum can include the involvement of multiple organs to varying degrees. Rhabdomyolysis with renal function impairment is frequently noted in this disease. However, acute hepatic failure has been rarely reported in non-exertional heat stroke. We report a case of acute hepatic failure combined with disseminated intravascular coagulopa...

BACKGROUND There seems to be a discrepancy between the available heat stress guidelines and the actual risk of heat-related illness among professional beach volleyball players competing under hot and humid conditions. OBJECTIVE To monitor heat stress and record cases of heat-related medical forfeits on the Swatch FIVB Beach Volleyball World Tour. METHODS The FIVB Heat Stress Monitoring Prot...

original article   introduction: direct sunlight and increased heat load influence mental and physical health of workers negatively and result in performance impairment. activity reduction is a natural body response to increase in internal body temperature, and a compensatory mechanism to make body balanced. this study was carried out to estimate productivity loss due to heat exposure among ira...
