The Bystander Effect of Ultraviolet Radiation and Mediators
A bystander effect is biological changes in non-irradiated cells by transmitted signals from irradiated bystander cells, which causes the radiation toxic effects on the adjacent non-irradiated tissues. This phenomenon occurs by agents such as ionizing radiation, ultraviolet radiation (UVR) and chemotherapy. The bystander effect includes biological processes such as damage to DNA, cell death, ch...
متن کاملThe Effect of Short-Range Radiation of Type C and B Ultraviolet on the Mechanical Properties of Skin Fibroblasts
The effect of UV beam, which has been emitted from a natural or a manmade source on cells has been studied in previous studies for several times. Radiation of this beam can have different effects on DNA of the cell, cytotoxicity, the structure of cellular proteins and their mechanical properties based on radiation period or frequency. The effect of radiation of two types of beams, namely UVB an...
متن کاملThe measurement of solar ultraviolet radiation in Kermanshah city over a one-year period from 2015 to 2016
ABSTRACT Background: Ultraviolet radiation is present in sunlight. If ultraviolet radiation exceeds the limit, it can cause detrimental effects on human health such as skin cancer and cataract. Materials and Methods: In this descriptive cross-sectional study, the level of solar ultraviolet radiation type A (UVA) were measured using UV LOG HAND HELD in Kermanshah city. The intensity of ultravio...
متن کاملMorphological and Biochemical Responses of Basil Plant Under Ultraviolet Radiation-B and Deficit Irrigation Under Greenhouse Conditions
Environmental stresses such as deficit irrigation and ultraviolet radiation can influence plant growth and development. Among the environmental variables, ultraviolet radiation is an important factor in plant response to other stresses, such as deficit irrigation. The purpose of this study was to investigate the effects of ultraviolet B radiation (UV-B), irrigation stress and combined effects o...
