Identification of anthocyanins in black rice (Oryza sativa L.) by UPLC/Q-TOF-MS and their in vitro and in vivo antioxidant activities
Abstract Anthocyanins in different types of black rice are different and their in vivo antioxidant activity is poorly studied. In this study, nine anthocyanins were detected by high performanceExpand

Increased Endothelial Nitric-Oxide Synthase Expression Reduces Hypertension and Hyperinsulinemia in Fructose-Treated Rats
Endothelial dysfunction and decreased production of nitric oxide (NO) by endothelial NO synthase (eNOS) are implicated in the pathogenesis of hypertension and insulin resistance. Because theExpand

Simultaneous quantification of polymethoxylated flavones and coumarins in Fructus aurantii and Fructus aurantii immaturus using HPLC-ESI-MS/MS.
The major lipid-soluble constituents in Fructus aurantii (zhiqiao) and Fructus aurantii immaturus (zhishi) are polymethoxylated flavones (PMFs) and coumarins. In the present study, a high-performanceExpand

Regulation of alpha-cell function by the beta-cell during hypoglycemia in Wistar rats: the "switch-off" hypothesis.
The glucagon response is the first line of defense against hypoglycemia and is lost in insulin-dependent diabetes. The beta-cell "switch-off" hypothesis proposes that a sudden cessation of insulinExpand

Intrarenal Dopamine Inhibits Progression of Diabetic Nephropathy
The kidney has a local intrarenal dopaminergic system, and in the kidney, dopamine modulates renal hemodynamics, inhibits salt and fluid reabsorption, antagonizes the renin-angiotensin system, andExpand

Intrarenal dopamine modulates progressive angiotensin II-mediated renal injury.
It is well-recognized that excessive angiotensin II (ANG II) can mediate progressive renal injury. Previous studies by us and others have indicated that dopamine may modulate actions of ANG II in theExpand

New triterpenoid saponins from Ilex cornuta and their protective effects against H2O2-induced myocardial cell injury.
Five new triterpenoid saponins, 1-5, together with 10 known ones, 6-15 were isolated from the aerial parts of Ilex cornuta. The structures of compounds 1-5 were determined asExpand

Black TiO2 nanobelts/g-C3N4 nanosheets Laminated Heterojunctions with Efficient Visible-Light-Driven Photocatalytic Performance
Black TiO2 nanobelts/g-C3N4 nanosheets laminated heterojunctions (b-TiO2/g-C3N4) as visible-light-driven photocatalysts are fabricated through a simple hydrothermal-calcination process and an in-situExpand

BGP-Reflection Functors and Lusztig's Symmetries: A Ringel–Hall Algebra Approach to Quantum Groups
According to the canonical isomorphisms between the Ringel–Hall algebras (composition algebras) and the quantum groups, we deduce Lusztig's symmetries T″i, 1, i ∈ I, by applying theExpand

Intrarenal dopamine deficiency leads to hypertension and decreased longevity in mice.
In addition to its role as an essential neurotransmitter, dopamine serves important physiologic functions in organs such as the kidney. Although the kidney synthesizes dopamine through the actions ofExpand
