Thallium (Tl) is one of the most toxic heavy metals affecting both humans and animals, yet least studied for its toxicological effects. A total 40 male Wistar rats were randomly divided into four Groups with 10 in each Group. Group I received distilled water only served as a control. II, III, IV thallium sulfate (I) at 0.48, 0.93, 1.33 mg/kg body weight, respectively, drinking 90 days. In rats,...

The polycyclic aromatic hydrocarbons (PAHs) phenanthrene and retene (7-isopropyl-1-methyl phenanthrene) are lethal to rainbow trout (Oncorhynchus mykiss) larvae during chronic exposures. Phenanthrene is a low-toxicity, non-cytochrome P4501A (CYP1A)-inducing compound that accumulates in fish tissues during exposure to lethal concentrations in water. Retene is a higher toxicity CYP1A-inducing com...

Purpose To evaluate the feasibility of acute and chronic toxicity in patients suitable for accelerated partial breast irradiation (APBI) in a single 18 Gy fraction with multicatheter high-dose-rate (HDR) brachytherapy, as well as cosmetic and oncological outcomes. Material and methods Between September 2014 and March 2016, twenty consecutive patients with low-risk invasive and ductal carcinom...

BACKGROUND This is the first published assessment on agricultural pesticide use in Iran with the aim to identify pesticide products with a potential of causing acute or chronic hazard to human health. It also establishes a baseline for future comparisons and for trend assessments. METHODS The amounts of imported technical materials for formulation by local manufacturers as well as imported fi...

Urban road dust contains a variety of pollutants and might deteriorate the environment quality in the receiving water bodies of urban runoff. Urban road dust may be accumulated in the sediment for the periods of time, thus chronic toxicity should be evaluated. However, toxicity assessment of urban road dust is limited especially in the chronic effect on benthic organisms. This study aimed to as...
