Receptor-interacting protein 3 (RIP3), a member of RIP family proteins, has been shown to participate in programmed necrosis or necroptosis in cell biology studies. Evidence suggests that necroptosis may be a mode of neuronal death in the retina. In the present study we determined the expression of RIP3 in normal rat retina and its changes following acute(More)
BACKGROUND Compound Danshen Tablet (CDT), a Traditional Chinese Medicine, has recently been reported to improve spatial cognition in a rat model of Alzheimer's disease. However, in vivo neuroprotective mechanism of the CDT in models of spatial memory impairment is not yet evaluated. The present study is aimed to elucidate the cellular mechanism of CDT on(More)
Four new steroids with an acetoxy linked at the end of the side chain, echrebsteroids A-D (1-4) were obtained from the South China Sea gorgonian Echinogorgia rebekka. The absolute configurations of 1-3 were determined using the modified Mosher's method on the hydrolysis products. The isolation of the pair of epimers (2 and 3) represents the first reported(More)
BACKGROUND Whereas chronological age (CA) cannot distinguish functional differences among individuals of the same age, the biological age (BA) may be used to reflect the functional state of the body. The purpose of this study was to construct an integral formula of the BA, by using principle component analysis (PCA). METHODS The vital organ function of(More)
Gorgonians of the family Ellisellidae (Gorgonaceae) are well known to be a rich source of several closely related briarane diterpenoids. The diterpenoids isolated from this family are characterized by 11,20-epoxy, 8-hydroxy, and 3,5(6)-diene/or 3,5(16)-diene with 6-chlorine functionalities, displaying various biological activities, such as antifouling,(More)
BACKGROUND Atorvastatin calcium is a 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor indicated for the prevention of cardiovascular disease and for the treatment of dyslipidemia. Information on the pharmacokinetics of atorvastatin in a Chinese population is lacking, and regulatory requirements necessitate a bioequivalence study for the marketing(More)
Sulcardine sulfate (Sul), a novel antiarrhythmic agent, is currently in phase I and phase II clinical trials. To elucidate its clinical pharmacokinetic characteristics, a rapid and accurate liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been developed and validated for the quantification of Sul in human plasma. Plasma samples were(More)
BACKGROUND Losartan is a nonpeptide angiotensin II receptor antagonist used as an antihypertensive agent. The relative bioavailability of a newly developed tablet compared with an established branded formulation has not been reported in a Chinese population. OBJECTIVE To meet the requirements for marketing a new generic product, the study was designed to(More)
Most depressed patients suffer from sleep abnormalities, which are one of the critical symptoms of depression. They are robust risk factors for the initiation and development of depression. Studies about sleep electroencephalograms have shown characteristic changes in depression such as reductions in non-rapid eye movement sleep production, disruptions of(More)
UNLABELLED BACKGROUND Our previous studies indicated that oxidative stress up-regulated the expression of β-amyloid precursor protein cleavage enzyme-1 (BACE1) in rat retina. Pharmacological reports have shown Timosaponin-BII, a purified extract originating from Chinese medical herb Rhizoma Anemarrhenae, is characterized as an antioxidant. Our present(More)
