conclusions these results exhibited the immuno potentiator effects of mip-3beta plasmid when coadministrated with the hcv core dna vaccine. complimentary studies integrating mip-3beta as a genetic adjuvant in hcv-core-dna vaccination models are warranted. results mice covaccinated with mip-3beta elicited an enhanced th1 biased systemic immune response as evidenced by higher ifn-γ/il-4 and anti-...
background: plasmodium vivax malaria accounts for approximately 88% of malaria cases in iran. there is limited information on genetic diversity of p. vivax in the country and a need to develop and apply an effective vaccine against the disease is necessary. among many potential candidates, msp -3β gene is promising target. this study was designed and carried out to determine the variation of...
Previous reports suggest that burn-induced muscle proteolysis can be inhibited by treatment with GSK-3beta inhibitors, suggesting that burn injury may be associated with increased GSK-3beta activity. The influence of burn injury on muscle GSK-3beta activity, however, is not known. We determined the effect of a 30% total body surface full-thickness burn injury in rats on muscle GSK-3beta activit...
Four new ursane-type triterpenes, 3beta-acetoxy-11alpha-methoxy-12-ursene (1), 3beta-acetoxy-11alpha-ethoxy-12-ursene (2), 3beta-acetoxy-11alpha-hydroperoxy-12-ursene (3), 3beta-hydroxy-11alpha-hydroperoxy-12-ursene (4), and two new oleanane-type triterpenes, 3beta-acetoxy-11alpha-ethoxy-12-oleanene (5), 3beta-acetoxy-111alpha-hydroperoxy-12-oleanene (6), together with 3beta-acetoxy-11alpha-hyd...
Fractionation of a steam distilled residue of Commiphora confusa resin has yielded four novel dammarane triterpenes characterised as (20S)-3beta-acetoxy-12beta,16beta-trihydroxydammar-24-ene, (20S)-12beta,16beta-trihydroxydammar-24-ene-3beta-O-beta-glucopyranoside, (20S)-3beta-acetoxy-12beta,16beta,25-tetrahydroxydammar-23-ene, and (20S)-3beta,12beta,16beta,25-pentahydroxydammar-23-ene. The kno...
Glycogen synthase kinase (GSK)-3, a negative regulator of cardiac hypertrophy, is inactivated in failing hearts. To examine the histopathological and functional consequence of the persistent inhibition of GSK-3beta in the heart in vivo, we generated transgenic mice with cardiac-specific overexpression of dominant negative GSK-3beta (Tg-GSK-3beta-DN) and tetracycline-regulatable wild-type GSK-3b...
The purpose of this study was to determine whether exogenous zinc prevents cardiac reperfusion injury by targeting the mitochondrial permeability transition pore (mPTP) via glycogen synthase kinase-3beta (GSK-3beta). The treatment of cardiac H9c2 cells with ZnCl2 (10 microM) in the presence of zinc ionophore pyrithione for 20 min significantly enhanced GSK-3beta phosphorylation at Ser9, indicat...
When Chlorella sorokiniana was cultured in the presence of 1 mg/1 triparanol succinate, there was a 42% reduction in total sterol concentration. Algal biomass was reduced by approximately the same amount. In addition to the cycloartenol, cyclolaudenol, 24-methyl-pollinastanol, ergosta-5, 7-dien-3beta-ol, and ergosterol that occur in control culture, pollinastanol, 14alpha-methyl-5alpha-ergost-8...
Four new cucurbitane-type triterpenes, cucurbita-5,23(E)-diene-3beta,7beta,25-triol (1), 3beta-acetoxy-7beta-methoxycucurbita-5,23(E)-dien-25-ol (2), cucurbita-5(10),6,23(E)-triene-3beta,25-diol (5), and cucurbita-5,24-diene-3,7,23-trione (6), together with four known triterpenes, 3beta,25-dihydroxy-7beta-methoxycucurbita-5,23(E)-diene (3), 3beta-hydroxy-7beta,25-dimethoxycucurbita-5,23(E)-dien...
