medicinal plants are a source of great economic value all over the world. nature has bestowed on us a very rich botanical wealth and large number of diverse types of plants grows in different parts of the country. in this study the in vitro antimicrobial activity of crude ethanolic, methanolic and water extracts of the stem bark of o.basilicum were investigated. the extracts exhibited antimicro...

ABSTRACT Mass methanol poisonings present a serious problem for health systems worldwide, with poor outcome associated with delayed treatment. Positive pre-hospital serum ethanol concentration may have predictive value as the prognostic factor of the treatment outcome. We studied the effect of positive serum ethanol level on admission to hospital on survival in patients treated during the Czech...

In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...

The treatment performance and spatial microbial community structure of three parallel denitrifying biological filters (DNBFs) operated with methanol, ethanol and acetate, respectively, were explored. The acetate-fed DNBF presented the highest denitrification rate and NOx-N (NO2-N and NO3-N) removal efficiency, while the methanol-fed DNBF showed the lowest carbon consumption and NOx-N removal ef...

Biofuels are receiving increased scientific attention, and recently different biofuels have been proposed for spark ignition engines. This paper presents the state of art using in engines (SIE). Different biofuels, mainly ethanol, methanol, i-butanol-n-butanol, acetone, blended together single dual issues evaluated as renewables SIE. The were compared with each other well fossil fuel Future SIE...

Background Formic acid (formate) is the main reason for toxicity and death through methanol poisoning. The simultaneous determination of methanol, ethanol, and formate in the body can help to discover the cause of death and is useful in the diagnosis of acute methanol poisoning. The measurement of formate is not yet available in Iran. With regard to the increasing rate of methanol poisoning and...

background consumption of home-distilled alcohol may lead to epidemic or sporadic cases of severe acute methanol poisoning. the difficulty of establishing strict indications for hemodialysis in acute methanol poisoning is a widely recognized issue. materials and methods the determination of the clinical, especially hemodialysis, and para clinical factors influencing patient survival in 46 acute...

background: histamine is a food-borne chemical hazard which causes scombroid poisoning. the efficiency of histamine recovery from fish is greatly influenced by selection of an appropriate extraction solvent. hence, in this study the efficiency of different extraction solvents on recovery of histamine from fresh, frozen and canned fish was evaluated. methods: fresh, frozen and canned rainbow tro...

In this work, the characteristics of wood degradation using supercritical alcohols have been studied. Supercritical ethanol and supercritical methanol were used as solvents. The kinetics of wood degradation were analyzed using the nonisothermal weight loss technique with heating rates of 3.1, 9.8, and 14.5 °C/min for ethanol and 5.2, 11.3, and 16.3 °C/min for methanol. Three different kinetic a...

The antibacterial activity of methanol, ethanol, chloroform, and hexane extracts of the leaves of Himalayan gymnospermous plant Ginkgo biloba L. was assessed against five animal and plant pathogenic strains (Agrobacterium tumefaciens, Bacillus subtilis, Escherichia coli, Erwinia chrysanthemi, and Xanthomonas phaseoli) employing disc-diffusion and broth-dilution assays. The methanol extract show...
