background the aim of the present study was to investigate the effect of ginger and glibenclamide on oxidative stress markers. oxidative stress is caused by an unbalance between a relative overload of oxidants and depletion of antioxidants, as implicated in the pathogenesis of several chronic diseases, including atherosclerosis and diabetes mellitus. regarding the role of oxidative stress in th...

background & aim: free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. antioxidants may have an important role in the prevention of these diseases. the aim of this study is to evaluate potency of scavenging of dpph free radic...

in this study, we measured the composition and free radical scavenging activity of several species of nuts, namely, torreya grandis, carya cathayensis,and myrica rubra. the nut kernels of the aforementioned species are rich in fatty acids, particularly in unsaturated fatty acids, and have 51% oil content. t. grandis and c. cathayensis are mostly produced in zhejiang province. the trace elements...

objective: recent studies have shown that the use of prolonged and intermittent normobaric hyperoxia (95%) decrease the infarct volume of stroke. the aim of current study was to study the effect of an oxygen radicals-scavenger applied during intermittent normobaric hyperoxia on infarct volume in the rat brain and neurologic deficit. materials and methods: male wistar rats (250-350 g) were divi...

background: brucella species can cause infection in a wide range of animals and human beings. oxidative events against brucella infection are not well elucidated. it is possible that brucellosis may be related to increased free radical production and antioxidant depletion. thus, the aim of this study was to determine the total antioxidant capacity (tac) before and after treatment of patients wi...

Background: Free radicals and reactive oxygen species(ROS) are the most important factors in formation of oxidative stress reaction. Now, radical damage has been suggested to contribute to a wide variety of diseases such as Alzheimer, atherosclerosis and cancer. Transition metal ions in the presence of the various biomolecules produce these active compounds. The aim of this study is introducing...

objective(s):astrodaucus persicus, apiaceae, is used as vegetable or food additive in some parts of iran. the essential oils of different parts of astrodaucus persicus from kordestan province were analyzed for the first time and compared with other regions. in this study, antioxidant activities and total phenols determination of aerial parts essential oils and root fractions of a. persicus were...

the side effects of synthetic antioxidants have been considered in different studies. accordingly, there is an increasing interest toward the use of natural substances instead of the synthetic ones. in this study, the aqueous and ethanolic extracts of pistacia vera leaves and fruits as well as hydroalcoholic extract of gum were tested for a possible antioxidant activity using in vitro methods. ...

A vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as DNA, proteins and lipids. When free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. Therefore, the body should be protected by an enzymatic or no...
