A solvent system consisting of ethyl acetate, ethyl alcohol and water, in the volume ratio of 4.5:4.5:1, was developed and used to extract, at room temperature, betulin from white birch bark and antioxidants from spices (rosemary, thyme, sage, and oregano) and white oak chips. In addition, under reflux conditions, trimyristin was extracted from nutmeg using the same solvent system, and eugenol ...

the present study was conducted to determine the plant growth-promoting activities of bradyrhizobium sp. (vigna) strain mrm6 grown in the presence and absence of the selected herbicides, quizalafop-p-ethyl and clodinafop. the herbicide tolerant bradyrhizobium sp. (vigna) strain mrm6 was further tested for bioremediation and plant growth promoting potential using greengram as a test crop, grown ...

background and objectives:lallemantia iberica (lamiaceae) is a medicinal plant distributed in different parts of iran. this research, has evaluated the phytochemical constituents and antioxidant activity of the aerial parts of the plant. methods: different chromatographic methods such as column chromatographies using silica gel (normal and reversed phases), sephadex lh-20 and hplc were used for...

5-Ethyl-2'-deoxyuridine (5-ethyl-dUrd), an analog of thymidine, was evaluated for its capacity to inhibit herpes simplex virus (HSV) replication in vitro and in vivo. The 50% effective dose concentration of 5-ethyl-dUrd for HSV types 1 and 2 (HSV-1 and -2) cultured in Vero cells was 6 and 9 mug/ml, respectively. Levels of 5-ethyl-dUrd 14-fold in excess of the 50% effective dose for HSV-1 did no...

Telotristat ethyl, a tryptophan hydroxylase inhibitor, was efficacious and well tolerated in the phase 3 TELESTAR study in patients with carcinoid syndrome (CS) experiencing ≥4 bowel movements per day (BMs/day) while on somatostatin analogs (SSAs). TELECAST, a phase 3 companion study, assessed the safety and efficacy of telotristat ethyl in patients with CS (diarrhea, flushing, abdominal pain, ...

Background: Vitiligo is an acquired disease of skin that presents with depigmented patches due to lack of melanocytes in the epidermis. Accumulation of toxic free radicals like hydrogen peroxide in the epidermis may be responsible for melanocytes death. Since ethyl vanillate (vanillic acid ethyl ester) is a strong hydrogen peroxide scavenger, it may be effective against vitiligo. This study was...

All of the anesthetic (amylobarbitone, butobarbitone, pentobarbitone, phenobarbitone, and secobarbitone) and convulsant (5-ethyl-5(3'-methylbut-2-enyl) barbituric acid (3M2B) and 5-ethyl-5-(2'-cyclohexylidene-ethyl) barbituric acid (CHEB) barbiturates tested enhanced the binding of GABA to a carefully prepared P2 membrane fraction from rat brain in a dose-dependent manner. These findings are in...

Much evidence on the favorable effects of omega-3 ethyl esters on cardiovascular morbidity and mortality has been obtained in studies performed in healthy subjects and in different clinical settings. Here the clinical effects of omega-3 ethyl ester administration in patients with previous myocardial infarction or heart failure are reviewed, together with a discussion of underlying mechanisms of...

Treatment of the lysogenic strain M. lysodeikticus 53-40 (N5) with ethyl methylaminosulfonate results in a slight increase in infective center concentration of N5 phages which is only detectable once disturbing cells had been eliminated by lysozyme. After conversion of ethyl methylaminosulfonate with radioactive labelled guanosine at 37 degrees C, N7-ethyl-guanine could be ascertained. Therefor...

Abstract The fine chemical and pharmaceutical industries use large amounts of various organic solvents in their manufacturing processes. By reusing them, production costs can be significantly reduced. If we regenerate waste solvent mixtures, have the opportunity to reuse them process or other Our study illustrates an efficient regeneration using example a four-component mixture. Calculations we...
