background: gallic acid (ga) is an endogenous plant phenol known to have antioxidant, free radical scavenging ability, anti‑inflammatory, anti‑cancer, and anti‑fungal properties. the aim of this study was to assess the protective effect of ga on cyclophosphamide (cpa)‑induced hepatotoxicity in male wistar rats. methods: sixty rats were grouped into six groups of 10 rats per group. group 1 recei...
cardiac disorders remain one of the most important causes of death in the world. oxidative stress has been suggested as one of the molecular mechanisms involved in drug-induced cardiac toxicity. recently, several natural products have been utilized in different studies with the aim to protect the progression of oxidative stress-induced cardiac disorders. there is a large body of evidence that a...
schiff base sal-2,5-clan = 2-(2,5-dichlorobenzylideneamino)phenol used as a new precursor for preparation of poly-2-(2,5-dichlorobenzylideneamino)phenol (pdcbap). in an aqueous alkaline medium, naocl oxidant is capable of oxidative poly-condensation reaction (op). both sal-2,5-clan and pdcbap were characterized by solubility tests, ft-ir, 1h-nmr spectroscopy and tg-dta studies. ft-ir and 1h-nmr...
sperm is particularly susceptible to reactive oxygen species (ros) during critical phases of spermiogenesis. however, the level of seminal ros is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. mitochondria and sperm plasma membrane are two major sites of ros generation in sperm cells. besides, leukocytes including polymer phonu...
Background: The terms Reactive Oxygen Intermediates or Reactive Oxygen Species (ROS) are used to describe the molecules as highly reactive oxygen molecules that will chemically oxidize neighboring susceptible molecules. A prominent feature of radicals is that they have extremely high chemical reactivity, which explains not only their normal biological activities, but how they inflict damage on ...
In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage. Instead, these changes are the result of a highly evolved, stereotyped, and p...
Mitochondria plays a major role in maintaining homeostasis of heart cells. Mitochondria produce ATP and is the main intracellular source of reactive oxygen species (ROS) which can cause oxidative damage. Free oxygen radicals and oxidative damage are associated with cardiovascular pathology. Antioxidant defense can play an essential role in preventing oxidative damage by controlling free oxygen ...
enhanced oxidative stress in diabetes mellitus may contribute to the pathogenesis of diaetic complications. in this article, the stress oxidative generation has been studied in experimental diabetes by ferric reducing ability of plasma assay, a sensitive and simple method, and by other oxidative damage markers. the ferric reducing ability of plasma values as a total antioxidant capacity were si...
