Hypertonic saline (HS) inhalation therapy benefits cystic fibrosis (CF) patients [Donaldson SH, Bennet WD, Zeman KL, Knowles MR, Tarran R, Boucher RC. N Engl J Med 354: 241-250, 2006; Elkins MR, Robinson M, Rose BR, Harbour C, Moriarty CP, Marks GB, Belousova EG, Xuan W, Bye PT; the National Hypertonic Saline in Cystic Fibrosis (NHSCF) Study Group. N Engl J Med 354: 229-240, 2006]. Surprisingly...
Background and Objective: High density of industries and phenomena of dust make Ahvaz as one of the most polluted cities in Iran. The aim of current study was determination of cardiovascular death and hospital admissions respiratory disease of particulate matter less than 10 microns (PM10) on human health in Ahvaz, during 2010-2012. Materials and Methods: This descriptive study was conducted...
The accuracy of the Ischemic Score (IS) of Hachinski in the differential diagnosis between senile dementia (SDAT) and multi-infarct dementia (MID) is evaluated in this study. Ninety-four demented patients were subdivided on the basis of CT scan in three subgroups: 1) CT-SDAT (ventricular enlargement and widening of cortical sulci), 2) CT-MID (multiple low density areas attributable to ischemic ...
Background and purpose: Considerable increase on the use of electronic devices increased the rate of public occupational exposure to extremely low frequency electromagnetic fields. Assessment of exposure to these fields is highly important due to potential health hazards. This study aimed at investigating the magnetic flux emission from extremely low frequency electromagnetic fields around powe...

Background and objectives: In recent decades, progress of telecommunication industry resulted in public availability to cost-effective cellular mobile hence, boom of base stations of cellular mobile in response to vast public demands. Base stations of cellular mobile are specific source of microwave production in a certain frequency in environment. Antennas are installed on high towers to creat...
Skin cancer incidence is highest in white-skinned people. Within this group, skin types I/II (sun sensitive/tan poorly) are at greater risk than skin types III/IV (sun tolerant/tan well). Studies in mice demonstrate that ultraviolet radiation (UVR)-induced suppression of cell-mediated immune function plays an important role in the development of skin cancer and induces a susceptibility to infec...
Background and aims: Extremely low frequency magnetic field (ELF) is part of Spectrum of electromagnetic waves with range 30 to 300 Hz. The average magnetic field exposures in the workplace have been found to be higher in “electrical occupations” than in other occupations such as office work. The interaction between magnetic fields produced by power lines and substations with living organisms a...
DNA damage induced by UV radiation is a critical event in skin photocarcinogenesis. However, the role of racial/ethnic origin in determining individual UV sensitivity remains unclear. In this study, we examined the relationships between melanin content and DNA damage induced by UV exposure in situ in normal human skin of different racial/ethnic groups, phototypes, and UV sensitivities. The mini...
OBJECTIVES The purpose of the study was (i) to identify the carcinogenic agents that may cause confounding when studying the exposure-response relationship between bitumen fume exposure and cancer among roofing membrane-manufacturing workers and roofers and (ii) to assess exposures to the identified carcinogens and bitumen fume in roofing membrane manufacturing and roofing in Finland and Denmar...
