Ethanolic extract of propolis (EEP) was tested as a protective agent against gamma irradiation in mice. The mice were exposed to 6 Gy gamma irradiation from a 60Co source, and were treated intraperitoneally with EEP, administered before and after their irradiation. While the non-treated mice expired within 12 weeks, the mice that received a series of EEP treatments survived the irradiation, and...

A precursor (pS) to the small subunit (S) of ribulose1-,5-bisphosphate carboxylase is the major product of cell-free protein synthesis directed by poly(A) containing RNA from Chlamydomonas reinhardtii. We present sequence data for in vitro-synthesized pS, for in vitro-synthesized S that in generated from pS by posttranslational incubation with a Chlamydomonas cell extract, and for in vitro-synt...

Antipyretic effect of petroleum ether and chloroform soluble fractions of ethanol extract of the roots of Vernonia cinerea was investigated. Intraperitoneal administration of boiled milk at a dose 0.5 ml/kg body weight in albino rabbit leads to pyrexia. Intraperitoneal (i.p. route) administration of petroleum ether and chloroform soluble fractions of ethanol extract of the roots of Vernonia cin...

Investigation of a DCM extract of the bark of Pleiogynium timoriense from the former Merck collection of natural product extracts for antiproliferative activity indicated that it was active with an IC50 value of 1.3 μg/mL against the A2780 ovarian cancer cell line. Bioassay-directed fractionation of this extract yielded the three new bioactive trihydroxyalkylcyclohexenones 1-3. Their structures...

Thin-layer chromatographic method, with postchromatographic derivatization, was applied for the purposes of the quality control of pharmaceutical preparations, containing S. officinalis L. extract. Six finished products underwent the analysis: capsules, tablets, two ointments, tincture and finished product being a mixture of ethanolic S. officinalis and Thymi vulgaris extracts. Chromatographic ...

We study the vacuum polarization functions on the lattice with exact chiral symmetry of overlap fermion by matching the lattice data at large momentum scales with the Operator Product Expansion (OPE). We extract the strong coupling constant α s (µ) in two-flavor QCD as Λ (2) MS = 0.234(9)(+16 − 0) GeV. From the analysis of the difference between the vector and axial-vector channels , we extract...

1. A soluble extract of bovine heart valves was obtained after the tissue had been pulverized at liquid-nitrogen temperatures in a mill. 2. Hyaluronic acid was isolated from the crude extract by sedimentation equilibrium in a caesium chloride density gradient (Franek & Dunstone, 1966). 3. Analysis of the product indicated that it contained 15% of protein and the molar ratio of glucuronic acid t...

Repressed PHO5 gene chromatin, isolated from yeast in the native state, was remodeled by yeast extract in a gene activator-dependent, ATP-dependent manner. The product of the reaction bore the hallmark of the process in vivo, the selective removal of promoter nucleosomes, without effect on open reading frame nucleosomes. Fractionation of the extract identified a single protein, chromodomain hel...

throughout the world, there has been an increasing incidence of fungal infections, and because of drug resistance and toxicity associated with long-term treatment with antifungal drugs search for new drugs to treat fungal infections is ongoing. the aim of this study was to evaluate the physicochemical properties and stability of creams containing different concentrations of zataria multiflora e...
