Many strategies have been developed in order to increase the efficiency of treatment and decrease side effects. Oxidative stress has been reported to play an important role on various path physiological states. Quercetin is a flavonoid commonly found in fruits and vegetables. It has … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 9,036 accessesView PDFCite
Research ArticleOpen accessIn the abstractNasal Administration of Quercetin Liposomes Modulate Cognitive Impairment and Inhibit Acetylcholinesterase Activity in HippocampusTerdthai Tong-Un, Supaporn Muchimapura, Wathita Phachonpai, Jintanaporn WattanathornProblem statement: Oxidative stress is a major factor implicated in the degeneration of cholinergic neurons in Alzheimer’s Disease (AD). Several reports have indicated that antioxidant intake is beneficial to delay or inhibit the progression of this disease. Presently, Acetylcholinesterase (AChE) inhibitors are the mainstay of therapy for AD. Quercetin, one of the flavonoids in fruits and vegetables, has a powerful … …Neuroscience International, Vol. 1, Issue 1 · 30 Jun 2010 · 7,173 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Research in Asia in the Period from 2000-2008R. R. Hafidh, A. S. Abdulamir, F. Abu Bakar et al.Problem statement: Plant antioxidants are natural plant products that inhibit the adverse effects of the Reactive Oxygen Species (ROS) produced in plants. Thus, antioxidants enable plants to survive. Depending on this principle, human beings started using some plants’ parts to cure from diseases many centuries ago, even before the discovery of microbes or disclosing the etiology of many human diseases. … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 8,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Rodent Model of Autism: Intraventricular Infusions of Propionic Acid Increase Locomotor Activity and Induce Neuroinflammation and Oxidative Stress in Discrete Regions of Adult Rat BrainDerrick F. MacFabe, Karina Rodríguez-Capote, Jennifer E. Hoffman et al.Innate neuroinflammatory changes, increased oxidative stress and disorders of glutathione metabolism may be involved in the pathophysiology of autism spectrum disorders (ASD). Propionic acid (PPA) is a dietary and gut bacterial short chain fatty acid which can produce brain and behavioral changes reminiscent of ASD following intraventricular infusion in rats. Adult Long-Evans rats were given intraventricular infusions of either PPA … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 12,618 accessesView PDFCite
