Effect of dietary protein on plasma uric acid, body weight, and oxidative stress in broilers
… is an important antioxidant due to its role as a free radical scavenger, and methods to elevate its plasma concentration may be important in animal health. In a preliminary study, the effect of dietary protein on plasma uric acid (PUA) was determined in 3-wk-old chicks. Twenty-four broiler chicks …

The role of potential antioxidant in medicinal drug-induced oxidative stress
… N-acetylcysteine (NAC), a synthetic thiol, is a free-radical scavenger and a precursor of glutathione (the main endogenous antioxidant). However, the negative charge of NAC at physiological pH limits its bioavailability. N-acetylcysteineamide (NACA) is neutral in charge and is believed to have …

Epigenetic Therapy of Lung Cancers: Anti-tumoral effect of valproate on small cell lung cancer
… promotes production of reactive oxygen species, free radical scavenger N-acetylcystein is not sufficient to inhibit apoptosis. As expected, VPA triggers hyperacetylation of histone H3 and increases expression of p21. VPA reduces levels of BclxL, induces cleavage of Bid, translocation of Bax to …

Effects of Pycnogenol on Microsomal Cytochrome P450 Activity and Apoptosis
… different pharmaceutical preparations as a free radical scavenger.</p> <p>Since few scientific studies have documented the pharmacologic effects of pycnogenol, our objective was to characterize the biological activity of pycnogenol. One study looked at the effects of pycnogenol on the three …

Fundamental Aspects Of Regenerative Cerium Oxide Nanoparticles And Their Applications In Nanobiotechnology
… propose that cerium oxide nanoparticles act as free radical scavenger (via redox reactions on its surface) to decrease the ROS induced cellular damages. Additionally, UV-visible spectroscopic studies indicated that cerium oxide nanoparticles possess auto-regenerative property by switching its …

Neuronal and Mitochondrial Protection in Chronic Parkinsonism
… (5 mg/kg, i.p), a known natural antioxidant and free radical scavenger was injected to the chronic MPD 5 days/week for 18 weeks. Melatonin alone did not alter the striatal neuronal, mitochondrial and motor functions in normal mice. However, melatonin was effective to reverse dopaminergic, …

Mechanochemical synthesis and evaluation of rubber-thermoplastic polymer blends
… was essentially a physical blend. The role of free-radical initiators such as benzoyl and dicumyl peroxide, on the behaviour of NR/PP(60/40) blends was investigated. It was shown that dicumyl peroxide was more effective than benzoyl peroxide in im proving mechanical properties of blends. Again …

A study of selected water-soluble hydrazyl free radicals
… and oxygenic species (RNS/ROS). Many RNS/ROS are free radicals. In response, a stable water-soluble free radical able to react with other free radicals could, in theory, act as a free-radical scavenger in vivo and detect, decrease or eliminate harmful free-radical activity. Salts of water-soluble …

Effects of Ubiquinol with Fluid Resuscitation following Hemorrhagic Shock
… to organ dysfunction.1 Ubiquinol is a potent free radical scavenger which is produced endogenously and functions as part of the mitochondrial respiratory chain.2 No study has been conducted to investigate the effects of ubiquinol related to HS. The overall aim of this study was to examine the …
