Research ArticleOpen accessIn the keywordsIntranasal Administration of Quercetin Liposome Decreases Anxiety-like Behavior and Increases Spatial MemoryJintanaporn Wattanathorn, Wathita Phachonpai, Aroonsri Priprem, Saengrawee SuthiparinyanontAt present, the effects of quercetin liposome on anxiolytic activity and cognitive function are unclearly known. In this study, male Wistar rats were administered quercetin liposome via intranasal route once daily continually for 4 weeks. The anxiolytic activity and cognitive enhancing effect were determined after single administration, 1, 2, 3 and 4 weeks of treatment using elevated plus maze test … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 9,091 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCognitive-Enhancing and Antioxidant Activities of Quercetin Liposomes in Animal Model of Alzheimer's DiseaseTerdthai Tong-un, Panakaporn Wannanon, Jintanaporn Wattanathorn, Wathita PhachonpaiProblem statement: Recent findings demonstrated the crucial role of oxidative stress on the pathophysiology of Alzheimer’s Disease (AD). Antioxidant intake is beneficial to delay or inhibit the progression of this disease. Quercetin, a bioflavonoid in fruits and vegetables, has a powerful antioxidant activity both in vitro and in vivo. Claims that quercetin has many biological activities. However, quercetin is rapidly … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 31 Oct 2010 · 7,880 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNasal Administration of Quercetin Liposomes Improves Memory Impairment and Neurodegeneration in Animal Model of Alzheimer's DiseaseTerdthai Tong-un, Supaporn Muchimapura, Jintanaporn Wattanathorn, Wathita PhachonpaiProblem statement: At present, the development of protective strategy against Alzheimer’s Disease (AD) is increasing its importance due to the high prevalence of AD, a limitation of therapeutic efficacy and its high impacts on economic and social aspects. The development of the preventive and therapeutic strategy to protect against the path physiology induced by free radicals in AD from antioxidant … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,743 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuercetin Liposomes via Nasal Administration Reduce Anxiety and Depression-Like Behaviors and Enhance Cognitive Performances in RatsTerdthai Tong-Un, Panakaporn Wannanon, Jintanaporn Wattanathorn, Wathita PhachonpaiProblem statement: At present, the prevalence of neuropsychological disorders particularly anxiety, depression and dementia are increase. 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 · 9,034 accessesView PDF Cite

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 · 7,170 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNeuroprotective Effect of Quercetin Encapsulated Liposomes: A Novel Therapeutic Strategy against Alzheimer’s DiseaseW. Phachonpai, J. Wattanathorn, S. Muchimapura et al.Problem statement: The prevalence of Alzheimer’s disease is increasing but the efficacy of treatment is still very limited due to various factors including the blood brain barrier. Recent findings demonstrated the crucial role of oxidative stress on the pathophysiology of disease. In addition the burden of blood brain barrier can be overcome by nasal administration and vesicle-carrier mediated delivery system. … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 9,449 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDF Cite
