The paper addresses problems arising from effects of natural environmental factors on toxicity of pollutants to organisms. Most studies on interactions between toxicants and natural factors, including those completed in the EU project NoMiracle (Novel Methods for Integrated Risk Assessment of Cumulative Stressors in Europe) described herein, showed that effects of toxic chemicals on organisms c...

conclusions this study showed that some lifestyle factors, particularly exposure to radiation, chemicals, pesticides, and contact with pets or livestock, can play an important role in etiology of leukemia. results exposure to radiation (p = 0.0001), chemicals (p = 0.02), pesticides (p = 0.01), and contact with pets or livestock (p = 0.0001) were associated with the risk of leukemia, but a histo...

Hydroxychloroquine (HCQ) is an antimalarial medication that can also be used to treat autoimmune diseases. However, it can produce irreversible changes to the retina that lead to visual impairment. The aim of this study was to determine the proportion of patients treated with HCQ who develop retinal toxicity and the risk factors for the development of HCQ-induced retinal toxicity among Iranian ...

results the mean qtc at baseline (pre-methadone) was 426 ± 34 msec and after being on methadone for an average of 8.72 ± 4.50 years was significantly higher at 450 ± 35 msec. no significant relationships were found between qtc prolongation and risk factors except for calcium. the methadone dosage was significantly higher in veterans with a qtc change above the mean change of ≥ 24 msec (88.48 ± ...

BACKGROUND A diagnosis of collagen vascular disease (CVD) may predispose to radiotherapy (RT) toxicity. The objective of the current study was to identify factors that influence RT toxicity in the setting of CVD. METHODS A total of 86 RT courses for 73 patients with CVD were delivered between 1985 and 2005. CVD subtypes include rheumatoid arthritis (RA; 33 patients), systemic lupus erythemato...
