Ahvaz can be regarded as one of the most polluted cities in the world in terms of air pollution. Successive years of drought and weather conditions in recent years have resulted in particulate matter (PM10) concentration in Ahvaz. In this study, using probability distribution techniques, an appropriate threshold to identify the PM10 maximum extreme concentrations (MEC) has been detected. Based ...
Introduction: The purpose and our novelty of the current study were to evaluate the HPA function in adult survivors of primary non-pituitary brain tumors and its association with treatment-related factors such as received dose to the organs at risk, age at irradiation, surgery, and adjuvant chemotherapy in patients treated with RT for brain tumors. Moreover, it aimed to achie...
background: this study was carried out to observe the radioprotective effects of rosemarinus officinalis leaves extract (roe) against radiation-induced histopathological alterations in liver of mice. materials and methods: adult swiss albino mice were exposed to 6 gy gamma radiation in the presence (experimental) or absence (control) of roe to study the qualitative and quantitative alterations ...
Fish are indicative species with a relatively balanced ecosystem. Underwater target fish detection is of great significance to fishery resource investigations. Traditional investigation methods cannot meet the increasing requirements environmental protection and investigation, existing technology has few studies on dynamic identification underwater small targets. To reduce disturbances solve pr...
BACKGROUND Heparanase, an endoglycosidase that cleaves heparan sulfate (HS), is involved in various biologic processes. Recently, an association between heparanase and glomerular injury was suggested. The present study examines the involvement of heparanase in the pathogenesis of Adriamycin-induced nephrotic syndrome (ADR-NS) in a mouse model. METHODS BALB/c wild-type (wt) mice and heparanase...

Dust is a common atmospheric phenomenon in Iran especially in central arid regions. This severely affects environment as well as resident’s health. Among the results of this phenomenon are Respiratory diseases, bash radiation, accelerated soil erosion, Desertification and degradation of ecosystems. Some dusts are originated from local desert conditions but adjacency to neighboring countries de...
