There are many photo-protective measures adopted for protection from the solar radiation especially the UV radiation spectrum, sunscreens being the main agents. Besides the traditional approach of topical use of sunscreens, both chemical and physical, a new approach has emerged to use systemic agents in the form of vitamins and minerals. In this review, we are describing the major aspects relat...

When someone is inactive the energy and oxygen accumulate to dangerous levels instead of being burned off. This creates an excess of free radicals. If one is consuming too many calories this adds more energy to the mitochondrion and contributes to the free radicals. Anti-oxidants generated within the mitochondrion can neutralise the free radicals and help prevent damage. Physical activity helps...

Purpose Axonal severing is critical to the irreversible disability that occurs over the course of multiple sclerosis (MS). Reactive oxygen species (ROS) are implicated in neurodegenerative aspects of MS: axonal spheroid formation, severing, and axoplasmic Ca elevation. However, the exact role of Ca in spheroid formation remains unclear. The mechanism of action of natural anti-oxidants such as l...

Zataria multiflora (ZM) is a thyme-like aromatic plant in the Lamiaceae family that grows in central and southern Iran. ZM is extensively used as a flavor ingredient in a wide variety of foods and is used as part of popular traditional folk remedies. In the present study, ZM essential oil (ZMO) was obtained from ZM leaves via hydro-distillation and then analyzed by GC-MS (gas chromatography-mas...

introduction: myocardial infarction (mi) is associated with increased oxidative stress and reduced antioxidants. some studies have shown that exercise training increases the serum level antioxidants. therefore, this study investigated the effect of rehabilitation training on antioxidant status in patients with myocardial infarction. materials and methods: in this study, 20 patients with myocard...

Dysregulated cell growth can be caused by increased activity of protein synthesis eukaryotic initiation factor (eIF) 4E. Dysregulated cell growth is also characteristic of atherosclerosis. It is postulated that exposure of vascular cells, such as endothelial cells, smooth muscle cells and monocytes/macrophages, to oxidants, such as oxidized low-density lipoprotein (oxLDL), leads to the elaborat...
