A life course epidemiology approach embraces the complexity of disease risk and acknowledges the long-term effects of physical, social, psychological, and behaviour pathways, operating across an individual's life, a community's generation, and a population's development, on health and well-being. Researchers who adopt a life course epidemiology approach broaden their ability to understand, expl...

Epidemiologic studies of the respiratory health effects of air pollution are intrinsically difficult because exposure is common, expected effects at concentrations found in developed countries are weak, random misclassification of exposure is common, and the respiratory health indicators have multiple etiologies. Exposures to air pollutants also are multidimensional, generally consisting of a m...

Allergic sensitisation of the respiratory tract by chemicals is associated with rhinitis and asthma and remains an important occupational health issue. Although less than 80 chemicals have been confirmed as respiratory allergens the adverse health effects can be serious, and in rare instances can be fatal, and there are, in addition, related socioeconomic issues. The challenges that chemical re...

Evidence has shown that housing conditions may substantially influence the health of residents. Different types of housing have different structures and construction materials, which may affect indoor environment and housing conditions. This study aimed to investigate whether people living in different types of housing have different respiratory health outcomes. The data from the 1999-2006 Nati...

background: mustard gas has different effects on different body systems such as respiratory tract, blood, gastrointestinal, skin, eye, endocrine and peripheral nervous system. objectives: the purpose of this study was to determine the quality of life in chemical warfare veterans due to sulfur mustard exposure. patients and methods: in a cross-sectional and analytic study, 242 patients who had a...

air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. it has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution.according to the world health organization, six major air pollutants include particle pollution, ground?level ozone, carbon mono...

BACKGROUND Both influenza viruses and air pollutants have been well documented as major hazards to human health, but few epidemiologic studies have assessed effect modification of influenza on health effects of ambient air pollutants. OBJECTIVES We aimed to assess modifying effects of influenza on health effects of ambient air pollutants. METHODS We applied Poisson regression to daily numbe...

The present study was undertaken to investigate the effects of Zataria multiflora and Eucalyptus globolus essential oils on some haematological parameters and respiratory burst activity in common carp (Cyprinus carpio). 260 fish (30±5g) were randomly distributed in 13 treatment groups each one in three replicates and different doses of essential oils in 16-17ºC were administrated. The fish were...
