Introduction: Photothermal therapy using gold nanoshells is one of cancer therapy methods. Gold nanoshells generally consist of a silica core and a thin gold shell. Fe3O4@Au core-shell can be used for magnetic targeted therapy. The objective of this study was investigation of the photothermal effects of magnetically targeted Fe3O4@Au NPs and NIR laser irradiation on model of me...

PURPOSE Biochemical research has demonstrated that lutein and zeaxanthin, the two macular carotenoids, are bleachable pigments. Further, evidence suggests that exposure to UV light can degrade plasma carotenoid levels in vivo. The present study investigated the effects of exposure to normal levels of light on the levels of lutein and zeaxanthin in the retina. METHODS The optical density of ma...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

background: the adverse effects of noise are well known and noise problems due to industrialization of communities are increasing over the time. oil industries due to the process and nature of production; contain many noise sources such as compressors, turbines, and pumps, which cause excessive noise exposure. the objective of this study was to evaluate the noise characteristics of compressors ...
