Chymotrypsinogen and chymotrypsin crystallize readily from dilute solutions of ethyl alcohol in the absence of salts. The crystals formed in the presence of alcohol differ in appearance from those formed in the presence of ammonium sulfate. Chymotrypsinogen yields well formed polyhedrons instead of fine needles usually produced in ammonium sulfate solution. Chymotrypsin yields fine needles in t...

Sedimentation properties of the TiO2 nanoparticles with very high specific surface area (about 180m /g) based on the BET method have been investigated in various organic solvents. The TiO2 nanocolloid in the isopropyl alcohol displayed a considerably high electrostatic repulsive force, compared to that in other solvents, with negligible coalescence between the particles. Both the backscattered ...

The present study mainly investigated the ability of solid-state cultures of the non-pathogenic Fusarium oxysporum strain BAFC 738 to transform aromatic components to reduce the phytotoxicity in olive-mill dry residue (DOR), the waste from the two-phase manufacturing process. Lignin, hemicellulose, fats and water-soluble extractives contents of DOR colonized by the fungus for 20 weeks were redu...

OBJECTIVE Studies have demonstrated frequent contamination of stethoscope and usefulness of different disinfectants. Albeit, studies on the precise mode of cleaning and frequency of cleaning are lacking. This study was carried out to determine efficacy of 66% ethyl alcohol as disinfectant, rate of recontamination without cleaning and benefits of daily versus immediate cleaning. METHODOLOGY Pr...

Direct Ethanol Metabolites. Currently available biological state markers of alcohol intake are limited in two basic respects: (1) Their time spectra are limited to only recent intake (e.g. serum ethanol detects only use within the past several hours) or long-term, chronic intake through measurement of adverse consequences of heavy drinking on end-organ functioning (gamma glutamyl transpeptidase...

Multidisciplinary forensic and pharmaceutical, organizational legal, technological study of alcohol-containing liquids as factors in the formation development polydrug addiction among public population Ukraine was conducted. Determined that combined intake several psychoactive substances leads to new variants addiction. Noted substances, main are containing ethyl alcohol. Classification stages ...

the whole plant, pergularia daemia (family: asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. the diuretic activity of the different extracts at a dose of 400 mg/kg was assessed orally in rats with furosemide as a standard drug using lipschitzs t...

BACKGROUND Previously, we reported the presence of hydroxytyrosol in red wine and higher human urinary recovery of total hydroxytyrosol than that expected after a single red wine intake. We hypothesized that the alcohol present in wine could promote endogenous hydroxytyrosol generation. OBJECTIVE The objective was to assess the relation between alcohol consumption and urinary hydroxytyrosol c...

Antiseptic preparations used repeatedly to disinfect the skin caused a reduction in yield of resident flora to a low equilibrium level beyond which further reduction did not occur. This equilibrium varied with the antiseptic preparation used. In a comparison of three preparations, the lowest equilibrium level was obtained with 95% ethyl alcohol. The further reduction in yield of skin bacteria o...

Introduction: The most common substance of abuse/dependence in patients presenting for treatment in western countries is alcohol. Ethyl alcohol or ethanol which is also called medicinal alcohol is used as an official drug compendium. It is also administered as an antidote in methanol poisoning. However, regular consumption of high amounts of alcoholic drinks induces dependence and addiction lea...
