Antioxidants are used to minimize the oxidative changes in meat and meat products. Oxidative changes may have negative effects on the quality of meat and meat products, causing changes in their sensory and nutritional properties. Although synthetic antioxidants have already been used but in recent years, the demand for natural antioxidants has been increased mainly because of adverse effects of...

BACKGROUND Adriamycin (ADR) is an effective chemotherapeutic agent against cancers but its clinical use is limited due to its cardiotoxicity. It has been suggested that the pathogenesis involves inhibition of nucleic acid and protein synthesis, free radical formation and lipid peroxidation. Schisandra (SC) has strong antioxidant activity. We investigate the protective effects of SC on adriamyci...
Muscular exercise promotes the production of radicals and other reactive oxygen species in the working muscle. Growing evidence indicates that reactive oxygen species are responsible for exercise-induced protein oxidation and contribute to muscle fatigue. To protect against exercise-induced oxidative injury, muscle cells contain complex endogenous cellular defence mechanisms (enzymatic and non-...
background: epilepsy is a chief communal health problem. antiepileptic drugs only provide symptomatic treatment. walnut kernels (wk) have high concentrations of phenolic compounds, which have beneficial effects on human health because of their antioxidant and anti-atherogenic properties. the present study was designed to evaluate the efficacy of wk supplementation for the prevention of experime...
background free radicals are known as atoms and molecules which are highly reactive with the body’s single-electrons, and may cause irrecoverable damages to the macromolecules of organisms. systems to deal with damages caused by free radicals are known as “antioxidant immune systems”. flavonoids and polyphenolic compounds are from non-enzymatic antioxidants which many nutritional compounds cont...
We developed new macromolecular engineering approaches enabling the preparation of star-shaped and antimicrobial polypeptoids by ring-opening polymerization.
Structure determination of a novel macromolecular complex via single-particle electron microscopy depends upon overcoming the challenge of establishing a reliable 3-D reconstruction using only 2-D images. There are a variety of strategies that deal with this issue, but not all of them are readily accessible and straightforward to use. We have developed a "toolbox" of ab initio reconstruction te...
Toxoplasma rhoptry neck protein 4 (TgRON4) is a component of the moving junction macromolecular complex that plays a central role during invasion. TgRON4 is exposed on the cytosolic side of the host cell during invasion, but its molecular interactions remain unclear. Here, we identified host cellular β-tubulin as a binding partner of TgRON4, but not Plasmodium RON4. Coimmunoprecipitation studie...
