Impacts of ionizing radiations and protective efficacy of phytochemicals: A review
The ionizing radiations have great impact on living cells and damage caused is owing to the multitude of ultra-fast physical and chemical reactions initiated by radiations. Irradiation of a biological system or exposure to radiation causes catastrophic damage. The ionizing radiations initiate free radical generation which causes damage to lipid membranes of the cell and cell organelles, induces...
متن کاملThe Effect of Radio-active Radiations and X-rays on Enzymes. I. the Effect 0~" Radiations Fro~ Radiu~ Emanation on Solutions O~ Trypsin. by Raymond G. Hussey An~
At the present time our information concerning the changes effected in living matter by x-rays and the radiations from radio-active substances is confined chiefly to the characteristic exudative phenomena noted in animal tissues, and the altered structural character of cells observed following exposures to these radiations. We have but little data bearing on the underlying physiological process...
متن کاملSome Effects of Radium Radiations on White Mice. by Kanematsu Sugiura and Gioacchino Failla
I t is well known that radium rays, as well as x-rays, are capable of affecting the living cell. Bergoni~ and Tribondeau 1 from extensive experimental studies made the generalization 2,3 that: "Immature cells and cells in an active state of division are more sensitive to the x-rays than are cells which have already acquired their fixed adult, morphological or physiological characters. ''2 Subse...
متن کاملExploiting Mycosporines as Natural Molecular Sunscreens for the Fabrication of UV-Absorbing Green Materials.
Ultraviolet radiations have many detrimental effects in living organisms that challenge the stability and function of cellular structures. UV exposure also alters the properties and durability of materials and affects their lifetime. It is becoming increasingly important to develop new biocompatible and environmentally friendly materials to address these issues. Inspired by the strategy develop...
متن کاملFunctional characterization of a DNA repair polymerase from a radiation resistant bacterium, Deinococcus radiodurans
Cells exposed to DNA damaging agents, produce different types of structural changes in the chromosome. Repair of these lesions requires synthesis of new DNA molecules, catalysed by specific DNA polymerases. A putative DNA polymerase has been characterized, for its role in DNA damage repair and radiation resistance in D. radiodurans, a bacterium best known for its extraordinary resistance to ...
