[ 1 ] - Evaluating the Expression of NOX2 and NOX4 Signaling Pathways in Rats’ Lung Tissues Following Local Chest Irradiation; Modulatory Effect of Melatonin

Lung injury is one of the major concerns for chest cancer patients that undergo radiotherapy as well as persons exposed to an accidental radiological event. Reduction/oxidation (redox) system plays a key role in lung injury via chronic upregulation of pro-oxidant enzymes. NOX2 and NOX4 are two important reactive oxygen species generating enzymes that are involved in radiation toxicity in some o...

[ 2 ] - Curcumin Mitigates Radiation-induced Lung Pneumonitis and Fibrosis in Rats

Radiation-induced lung injury is one of the most prominent factors that interfere with chest cancer radiotherapy, and poses a great threat to patients exposed to total body irradiation. Upregulation of pro-oxidant enzymes is one of the main mechanisms through which the late effects of ionizing radiation on lung injury can be exerted. Interleukin (IL)-4 and IL-13 are two important cytokines that...

[ 3 ] - Metformin Protects Against Radiation-Induced Heart Injury and Attenuates the Up-regulation of Dual Oxidase Genes Following Rat’s Chest Irradiation

Radiation-induced heart toxicity is one of the serious side effects after  a radiation disaster or radiotherapy for patients with chest cancers, leading to a reduction in the quality of life of the patients. Evidence has shown that infiltration of inflammatory cells plays a key role in the development of functional damages to the heart via chronic up-regulation of some pro-fibrotic and pro-infl...
