Ampelopsis grossedentata, a medicinal and edible plant, has been widely used in China for hundreds of years, and dihydromyricetin is the main active ingredient responsible for its various biological actions. We investigated the effects of dihydromyricetin on glucose and lipid metabolism, inflammatory mediators and several biomarkers in nonalcoholic fatty(More)
BACKGROUND Non-alcoholic fatty liver disease is a major health problem worldwide. Resveratrol is a natural polyphenol found in edible plants that has a variety of biochemical and physiological effects. AIMS To evaluate the effect of resveratrol on insulin resistance, glucose and lipid metabolism in non-alcoholic fatty liver disease. METHODS(More)
PURPOSE Acute hypobaric hypoxia (HH) causes persistent cognitive impairment, affecting memory function specifically. Mitochondrial dysfunction and synaptic morphological change were the prominent pathological features of HH exposure on brain. Quercetin, a flavonoid found in fruits, vegetables, leaves and grains, is reported to prevent ischemia induced by(More)
Irisin, derived from FNDC5, is an exercise-induced myokine that can stimulate the 'browning' of white adipose tissue, which is regulated by peroxisome proliferator-activated receptor γ coactivator 1 α (PGC-1α). Dihydromyricetin (DHM), a natural flavonoid, exerts its activities through PGC-1α activation. Here, we explored whether DHM could mimic the effects(More)
Acute aortic dissection (AAD) is a life-threatening cardiovascular disease caused by progressive medial degeneration of the aortic wall. A disintegrin and metalloproteinase with thrombospondin motifs 1 (ADAMTS1) is a recently identified extracellular metalloproteinase participating in the development of vascular disease, such as atherosclerosis. In the(More)
Uncontrolled activity of T cells mediates autoimmune and inflammatory diseases such as multiple sclerosis, inflammatory bowel diseases, rheumatoid arthritis, type 1 diabetes, and atherosclerosis. Recent findings suggest that enhanced activity of interleukin-17 (IL-17) producing T helper 17 cells (Th17 cells) plays an important role in autoimmune diseases(More)
Epoxyeicosatrienoic acids (EETs), synthesized from arachidonic acid by cytochrome P450 epoxygenases, are converted to dihydroxyeicosatrienoic acids by soluble epoxide hydrolase. EETs exert anti-inflammatory effects. However, the effect of EETs on humoral immunity is poorly understood. The present study is to investigate the potential role of EETs on B cell(More)
Foxp3(+) regulatory T cells (Tregs) play a critical role in maintaining immune self-tolerance. Reduced number and activity of Tregs are usually found in autoimmune and inflammatory diseases, and enhancing the differentiation of Tregs may be a promising therapeutic strategy. Some reports suggested an anti-inflammatory and anti-autoimmune potential for(More)
Inadequate oxygen availability—for instance at high altitudes—leads to hippocampal neurodegeneration and memory impairment. Although oxidative stress is one factor, the mechanism underlying the effects of hypobaric hypoxia (HH) are unclear, and effective strategies for preventing the resultant damage to the brain are limited. In the present study, we(More)
Propylene glycol alginate (PGA) was found to be able to dissolve in aqueous ethanol solution and applied to interact with zein to form a noncovalent binary complex by the antisolvent coprecipitation method at pH 4.0. Quercetagetin (Q) was employed to explore the Q-delivery potential of Zein-PGA binary complex. A fruit tree-like microstructure was observed(More)
