A marathon is a grueling endurance race, and runners are at risk of heatstroke. Therefore, the thermal environment course should be accurately assessed. Solar radiation, factor in environment, particularly affected by surrounding environment. In this study, we proposed method to calculate wet-bulb globe temperature (WBGT) short period time using geographic information system (GIS) data, conside...

BACKGROUND The present study aimed at demonstrating the heat stress situation (distribution and intensity) based on a standard and common heat stress index, Wet Bulb Globe Temperature (WBGT), during hot seasons and interpret the obtained results considering global warming and rising temperature in different parts of the country based on climate changes studied in Iran. METHODS Heat stress ass...

Excessive workplace heat exposures create well-known risks of heat stroke, and it limits the workers' capacity to sustain physical activity. There is very limited evidence available on how these effects reduce work productivity, while the quantitative relationship between heat and work productivity is an essential basis for climate change impact assessments. We measured hourly heat exposure in ...

A study was conducted to investigate the effects of heat stress on time-sharing performance. Twelve participants performed three dual-task scenarios and a multiple-task scenario for 2 h in each of six climates. The climates were obtained by generating each of three wet bulb globe temperatures (WBGT; 22, 28 and 34 degrees C) with two relative humidity levels (30 and 70%). The dual tasks selected...

BACKGROUND Global climate change is already increasing the average temperature and direct heat exposure in many places around the world. OBJECTIVES To assess the potential impact on occupational health and work capacity for people exposed at work to increasing heat due to climate change. DESIGN A brief review of basic thermal physiology mechanisms, occupational heat exposure guidelines and ...

BACKGROUND The ATP7A gene encodes the ATP7A protein, which is a trans-Golgi network copper transporter expressed in the brain and other organs. Mutations in this gene cause disorders of copper metabolism, such as Menkes disease. Here we describe the novel and unusual mutation (p.T1048I) in the ATP7A gene of a child with Menkes disease. The mutation affects a conserved DKTGT1048 phosphorylation ...
