any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Noise pollution is one of the prominent environmental problems affecting human health especially in developing countries. The impacts of noise on health should not be underestimated. Exposure to acoustical stimuli impairs not only the function of auditory system but also that of many other systems of human body. Previous investigations revealed that noise exposure could result in sleep disturba...

hepatic toxicity is the most serious adverse effect of anti tuberculosis drugs. this study was performed to evaluate efficacy of silymarin as a hepatoprotective herbal agent. in a randomized double blind clinical trial 70 new cases of pulmonary tuberculosis were divided into two groups. the intervention group was assigned to receive silymarin and the control group received placebo. tuberculosis...
background the involved neurotransmitter pathways in the postoperative shivering (pos) are poorly understood. recently, 5-hydroxytryptamine 3 (5-ht3) receptor antagonists have been reported to prevent pos. we investigated the effect of ondansetron, a 5-ht3 antagonist that is used to treat postoperative nausea and vomiting, on shivering. objectives this study aimed to compare the efficacy of ond...
