Rutin is derived from buckwheat, apples, and black tea. It has been shown to have beneficial anti-inflammatory and antioxidant effects. Ethanol is a central nervous system depressant and neurotoxin. Its metabolite, acetaldehyde, is critically toxic. Aldehyde dehydrogenase 2 (ALDH2) metabolizes acetaldehyde into nontoxic acetate. This study examined rutin's(More)
The abnormal maturation and ossification of articular chondrocytes play a central role in the pathogenesis of osteoarthritis (OA). Inhibiting the enzymatic degradation of the extracellular matrix and maintaining the cellular phenotype are two of the major goals of interest in managing OA. Ginseng is frequently taken orally, as a crude substance, as a(More)
Prion disorders are progressive neurodegenerative diseases characterized by extensive neuronal loss and accumulation of the abnormal form of the scrapie prion protein (PrP). Rutin is a flavonoid that occurs naturally in plant-derived beverages and foods and is used in traditional and folkloric medicine worldwide. In the present study, we evaluated the(More)
Chondrocyte apoptosis has been recognized as an important factor in the pathogenesis of osteoarthritis (OA). Hydrogen peroxide (H2O2), which produces reactive oxygen species, reportedly induces apoptosis in chondrocytes. The ginsenoside Rb1 (GRb1) is the principal component in ginseng and has been shown to have a variety of biological activities, such as(More)
It has been shown that phosphatidylcholine (PC) extracted from egg yolk possesses a variety of biological activities, such as anti-inflammatory and anti-oxidant effects, and prevents oxidative stress. The aim of this study was to evaluate the hepatoprotective effects of PC against carbon tetrachloride (CCl₄), which is a well-known hepatotoxicant that causes(More)
Phosphatidylcholine (PC) from egg yolk is a bioactive substance with various beneficial effects, including anti-inflammatory and anti-oxidant effects. Recently, this substance has been reported to prevent acute hepatotoxicity. In the present study, we aimed to evaluate the putative protective effect of PC on carbon tetrachloride (CCl4)-induced(More)
Although 6-shogaol, a constituent of ginger, has been reported to have anti-inflammatory and anti-oxidant effects on neuronal cells, the effects of 6-shogaol on Alzheimer's disease (AD) have not yet been investigated. Here we aimed to determine whether 6-shogaol exerts neuroprotective effects against AD. Specifically, we investigated the effects of(More)
It has been shown that the accumulation of prion in the cytoplasm can result in neurodegenerative disorders. Synthetic prion peptide 106-126 (PrP) is a glycoprotein that is expressed predominantly by neurons and other cells, including glial cells. Prion-induced chronic neurodegeneration has a substantial inflammatory component, and an increase in the levels(More)
The progressive degeneration and ossification of articular chondrocytes are main symptoms in the pathogenesis of osteoarthritis (OA). Several flavonoids may provide an adjunctive alternative for the management of moderate OA in humans. Rutin, a natural flavone derivative (quercetin-3-rhamnosylglucoside), is well known for its potent anti-inflammatory and(More)
BACKGROUND Alcoholism, which refers to the excessive consumption of alcohol, has deleterious effects on personal and social health worldwide. Oxidative stress evoked by ethanol plays an important role in the pathogenesis of neurodegenerative diseases. Rutin is a bioflavonoid that has been demonstrated to scavenge superoxide radicals. However, the effects of(More)
