Evaluation of Protective Effects of Nano-formulated Silymarin Against UV Radiation on Guinea Pig Skin
Background: As increased outdoor activities of people, they are more exposed to UV radiation, which causes harmful effects on skin. Silymarin has protective potentials against DNA damage and non-melanoma skin cancers, and also it has anti-oxidant, anti-inflammatory, and immune regulation characteristics. Nano formulation of plant material showed to be more effective than common ones. Object...
متن کاملRadiation & the environment: Assessing effects on plants and animals
The international body known as the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) periodically reviews the effects of ionizing radiation on the environment. Last year, the Committee, for the first time, issued a report that contained a review specifically focused on the effects of ionizing radiation on plants and animals.* While the review contained no surpris...
متن کاملRadiation hormesis and adoptive response induced by low doses of limiting radiation
Ionizing radiation has long been known to produce detrimental biological effects. Although these harmful effects are the results of high doses of exposure, some other maladies such as mutation and cancer seems to be induced at low doses of exposure. In recent decades, however, some pioneer scientists have indicated that ionizing radiation like many other essential agents has toxic effects ...
متن کاملEffects of electromagnetic field radiation on inducing physiological and biochemical changes in Satureja bachtiarica L. Fariba Ramezani Vishki1*, Ahmad Majd2, Taher Nejadsattari1 and Sedighe Arbabian2
As organisms exposed to various abiotic and biotic environmental impacts, plants are able to recognize and respond to their surrounding environment with high specificity. Electromagnetic field radiation is an important effective stress factor on growth and development of plants. Our research focused on plants grown from wet pretreated seeds with low frequency electromagnetic field exposure comp...
متن کاملRadiation-induced effects on plants and animals: findings of the United Nations Chernobyl Forum.
Several United Nations organizations sought to dispel the uncertainties and controversy that still exist concerning the effects of the Chernobyl accident. A Chernobyl Forum of international expertise was established to reach consensus on the environmental consequences and health effects attributable to radiation exposure arising from the accident. This review is a synopsis of the subgroup that ...

Introduction & Objective: Biological effects of ultraviolet (UV) radiation on the body of live organisms, have been studied by researchers in recent years. UV affects human organs such as skin, eyes and immune system, as well as animals and plants. The main natural source of UV radiation is the Sun. So, the integral observation of UV levels and their effects at ground level is important to dete...
