Oxidative stress can induce neuronal damages, modulate intracellular signaling and ultimately leads to neuronal death by apoptosis or necrosis. To review antioxidants preventive effects on oxidative stress and neurodegenerative diseases we accumulated data from international medical journals and academic informations' sites. According to many studies, antioxidants could reduce toxic neuronal damages and many studies confirmed the efficacy of polyphenol antioxidants in fruits and vegetables to reduce neuronal death and to diminish oxidative stress. This systematic review showed the antioxidant activities of phytochemicals which play as natural neuroprotectives with low adverse effects against some neurodegenerative diseases as Parkinson or Alzheimer diseases.}, Keywords = {Curcumin, Alzheimer, Resveratrol, Oxidative stress}, volume = {7}, Number = {2}, pages = {81-90}, publisher = {Iran University of Medical Sciences}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, doi = {10.15412/J.BCN.03070201}, url = {http://bcn.iums.ac.ir/article-1-492-en.html}, eprint = {http://bcn.iums.ac.ir/article-1-492-en.pdf}, journal = {Basic and Clinical Neuroscience}, issn = {2008-126X}, eissn = {2228-7442}, year = {2016} } @article{ author = {Kumar, Pradeep and Kumar, Amit and Srivastava, Mukesh Kumar and Misra, Shubham and Prasad, Kameshwar and KishorPandit, Awadh}, title = {Review Paper: Association of Transforming Growth Factor Beta-1 -509C/T Gene Polymorphism with Ischemic Stroke: A Meta Analysis}, abstract ={Introduction: Transforming Growth Factor-Beta 1 (TGF-&beta;1) is a pleiotropic cytokine with potent anti-inflammatory property, which has been considered as an essential risk factor in the inflammatory process of Ischemic Stroke (IS), by involving in the pathophysiological progression of hypertension, atherosclerosis, and lipid metabolisms. -509C/T TGF-&beta;1 gene polymorphism has been found to be associated with the risk of IS. The aim of this meta-analysis was to provide a relatively comprehensive account of the relation between -509C/T gene polymorphisms of TGF-&beta;1 and susceptibility to IS. Methods: A review of literature for eligible genetic association Studies published before October 20, 2014 was conducted in the PubMed, EMBASE, Google Scholar and Trip database. The strength of association was calculated by pooled odds ratios (ORs) with 95% confidence intervals using RevMan 5.3 software. Heterogeneity was examined using Higgins I-squared, Tau-squared, and Chi-squared tests. Results: A total of 2 studies involving 614 cases and 617 controls were found. The overall estimates did not show any significant relation between TGF-&beta;1-509C/T polymorphism and risk of IS under dominant (CC+CT vs. TT: OR=1.01, 95%CI=0.31 to 3.26; P=0.99), recessive (CC vs. CT+TT: OR=0.94, 95%CI=0.47 to 1.90; P=0.87), and allelic models (T vs. C: OR=1.06, 95%CI=0.55 to 2.04; P=0.86).

A potential therapeutic approach should possess several properties: Prevent immune system from damaging the brain and spinal cord, promote differentiation of oligodendrocyte progenitor cells (OPCs) into mature oligodendrocytes to produce myelin, prevent the formation of fibronectin aggregates by astrocytes to inhibit scar formation, and enhance function of healthy endothelial cells (ECs). Methods: To determine if an increase in sulfur contents through H2S, a potent antioxidant known to induce protective autophagy in cells, could provide the above desired outcomes, peripheral blood mononuclear cells (PBMNCs), OCPs, astrocytes, and ECs were treated with NaHS (50 &mu;M) in vitro. Results: Transmigration assay using EC monolayer showed that serotonin increased migration of PBMNC while pretreatment of EC with NaHS inhibited the migration induced by serotonin treatment. NaHS upregulated proteins involved in immune system response and downregulated PBMNCs- and EC-related adhesion molecules (LFA-1 and VCAM-1). Furthermore, it had a cell expansion inducing effect, altering EC morphology. The effects of NaHS on OPCs and astrocytes were studied compared to mTOR inhibitor rapamycin. In NaHS treated astrocytes the induced fibronectin production was partially inhibited while rapamycin almost fully inhibited fibronectin production. NaHS slowed but did not inhibit the differentiation of OCPs or the production of myelin compared to rapamycin.
