Methyl ganosinensate A (1), ganosinensic acid A (1a), and ganosinensic acid B (2), three new triterpenoids with an unusual four-membered ring skeleton produced by a bond across C-1 to C-11, were isolated from the fruiting body of Ganoderma sinense . Their structures were established on the basis of extensive spectroscopic methods, including 1D and 2D NMR(More)
A new pentanorlanostane, ganosineniol A (1), eight new lanostane triterpenoids, ganosinoside A (2), ganoderic acid Jc (3), ganoderic acid Jd (4), ganodermatetraol (5), ganolucidic acid γa (6), ganolucidate F (7), ganoderiol J ( 8), and methyl lucidenate Ha ( 9), and a new sesquiterpenoid, ganosinensine (10), together with eleven known triterpenoids (11-(More)
Mechanotransduction is a complicated process, of which mechanosensation is the first step. Previous studies have shown that the cytoskeleton plays a crucial role in mechanosensation and the mediation of intracellular signal transduction. However, the mechanism of mechanotransduction in the bone remains elusive. Here, we investigated the potential(More)
Component position and good fixation are important factors determining the success of a primary or revision total knee arthroplasty (TKA). The aim of this study was to measure the anatomic features of the tibial plateau and to assess variations in the offset of the tibial shaft from the tibial plateau in osteoarthritis (OA) patients. Computed tomography(More)
Three new cucurbitane triterpenoids 1-3 and one new steroidal glycoside 4, were isolated together with ten known compounds from Momordica charantia. The structures of new compounds were determined to be 19(R)-n-butanoxy-5 beta,19-epoxycucurbita-6,23-diene-3beta,25-diol 3-O-beta-glucopyranoside (1), 23-O-beta-allopyranosylecucurbita-5,24-dien-7(More)
Four new alkaloids, sinensines B–E (1–4), together with one known alkaloid, sinensine (5), were isolated from the fruiting bodies of Ganoderma sinense. Their structures were elucidated on the basis of 1D and 2D NMR spectra analysis. The structure of sinensine E was confirmed by X-ray crystallographic analysis of its acetyl product (4a).
Twelve limonoids, toonayunnanins A-L (1-12) and eleven known compounds (13-23) were isolated from the leaves of Toona ciliata var. yunnanensis, and their structures were elucidated by means of extensive spectroscopic analyses, particularly 1D and 2D NMR techniques. The inhibitory effects of all the isolated compounds were evaluated on human tumor cell(More)
The effects of large-dose oral arginine administration on the secretion of insulin by islet β-cells in healthy adults were determined. Eight non-obese healthy volunteers with normal glucose tolerance participated randomly in tests with four stages (with an interval of at least 3 days): the 300 ml purified water stage (PWS), the 75 g glucose stage (GSS), the(More)
One new limonoid of the phragmalin type (1) named Swietenine J with nine known compounds methyl-6-β-hydroxy angolensate (2), 1-O-acetylkhayanolide A(3), Khayanolide E (4), Khayalactone (5), Khayanone (6), 1-O-Acetylkhayanolide B (7), 1-O-Deacetylkhayanolide E (8), Khayanolide A (9), Khayanolide B (10) were isolated from Swietenia macrophylla. The structure(More)
A new pregnane glycoside, named (20R)-O-(3)-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl-pregn-5-en-3β,20-diol (1), and seven known compounds, brusatol (2), bruceine B (3), bruceine D (4), yadanziolide A (5), bruceine E (6), yadanzioside G (7), and yadanzioside B (8), were isolated from the cultivated dry seeds of Brucea javanica. The structure of 1 was(More)
