Polydatin is one of main compounds in Polygonum cuspidatum, a plant with both medicinal and nutritional value. The possible hepatoprotective effects of polydatin on acute liver injury mice induced by carbon tetrachloride (CCl(4)) and the mechanisms involved were investigated. Intraperitoneal injection of CCl(4) (50 µl/kg) resulted in a significant increase(More)
Hypertrophic scarring is a common proliferative disorder of dermal fibroblasts characterized by collagen overproduction and excessive deposition of extracellular matrix (ECM). There is no consensus about the best therapeutics to produce complete and permanent improvement of scars with few side effects. To investigate the therapeutic effects of oleanolic(More)
Two new triterpenoid saponins, caraganins A and B (1 and 2), structurally characterized by a 22-oxo group, were isolated from the seeds of Caragana microphylla Lam., together with their n-butyl esters as artifacts (1a and 2a). Their structures and configurations were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS data.(More)
The genus Fagopyrum (Polygonaceae), currently comprising 15 species of plants, includes three important buckwheat species: Fagopyrum esculentum (F. esculentum) Moench. (common buckwheat), Fagopyrum tataricum (F. tataricum) (L.) Gaertn. (tartary buckwheat) and Fagopyrum dibotrys (F. dibotrys) (D. Don) Hara. (perennial buckwheat), which have been well(More)
ETHNOPHARMACOLOGICAL RELEVANCE There are many plants of genus Piper which have been reported to induce antidepressant-like effects, Piper sarmentosum (PS) is one of them. PS is a Chinese herbal medicine and a traditional edible vegetable. MATERIALS AND METHODS In the present study, the antidepressant-like effects of PS extracts and the ethyl acetate(More)
To investigate anti-arthritic effects of matrine isolated from the roots of S. flavescens on type II collagen-induced arthritis (CIA) in rats and to explore its related potential mechanisms, CIA rats were established and administered with matrine (20, 40 or 80 mg/kg/days, for 30 days). Subsequently, blood was collected to determine serum levels of TNF-α,(More)
Histone H3 lysine 9 dimethylation (H3K9me2) hypermethylation is thought to be a major influential factor in cellular reprogramming, such as somatic cell nuclear transfer (SCNT) and induction of pluripotent stem cells (iPSCs). The diazepin-quinazolin-amine derivative (BIX-01294) specifically inhibits the activity of histone methyltransferase EHMT2(More)
BACKGROUND Clinical and preclinical observations indicate that Lactobacillus plantarum has anti-inflammatory activity and may regulate the immune responses of its hosts when ingested. Recently, modification of teichoic acids (TAs) produced by L. plantarum was reported as a key to regulating the systemic immune response in mice. However, data linking(More)
Chemical investigation of Vitex negundo seeds afforded four new lignans, including a phenylindene-type lignan, vitexdoin F (1), and three phenylnaphthalene-type lignans, vitexdoins G, H and I (2-4). Their structures were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS data. All compounds were evaluated for their(More)
A privacy preserving classification algorithm based on random Multidimensional Scales(MDS) is presented in this paper. We first alter the selection of the parameter embedded dimension d for satisfying the security of privacy preserving classification. Further the sensitive attributes are embedded into random(even higher) dimension feature space using random(More)
