The present study demonstrated that an omega (n)-3 fatty acid, ethyl-eicosapentaenoic acid (ethyl-EPA), supplemented diet significantly attenuated the stress/anxiety behavior of rats in the "open field" and elevated plus maze, which was induced by subchronic intracerebroventricular administration of proinflammatory cytokine interleukin (IL)-1beta. Ethyl-EPA also reduced the rise in serum cortic...

This study measured the possible cross-reactivity of hapten-specific IgG antibodies purified from the sera of rabbits sensitized to an albumin-acetaldehyde conjugate [N-ethyl-rabbit serum albumin (N-ethyl-RSA)] with acetaldehyde-phosphatidylethanolamine adducts. The N-ethyl-RSA was coupled to an Affigel-10 column to affinity purify the IgG (anti-N-ethyl-RSA IgG). Dioleoyl-phosphatidylethanolami...

Structural modifications of the multipotential carcinogen ethyl carbamate (urethan), CH3CH2—O---CO—-NH2, generally result in dramatic losses of carcinogenic activity, which usually have been assayed by lung adenoma induction and by initiation of skin papillomas in mice (reviewed in Refs. 12 and 20). One exception is ethyl N-hydroxycanbamate, CH3CH2— O—CO—-NHOH, a metabolite of ethyl c...

Characteristic aroma volatile compounds from different parts of cayenne pineapple were analyzed by headspace-solid phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS). The main volatile compounds were esters, terpenes, ketones and aldehydes. The number and content of aroma compounds detected in pulp were higher than those found in core. In pulp, the characteristic a...

the seasonal variation of volatile oil compositions (vocs) from fresh flowers of persian musk rose was investigated by combi pal headspace techniques. in this study, a total number of 21 vocs were detected by headspace on the combi pal system and gas chromatography-mass spectrometry (hs-gc/ms) from rosa moschata herrm. at different seasons which was representing 92.53-99.37% of total vocs. the ...

the synthesis of functionalized 2-oxo-2h-coumarin derivatives has been studied by a one-pot reaction of o-hydroxybenzaldehyde, ethyl 2-bromoacetate and triphenylphosphine in the presence of catalytic amount of triethyl amine in etoac, water or under solvent free conditions. we have found the best results obtained under solvent free condition.

in the chemical industry, process intensification is needed to meet important goals such as sustainable and eco-friendly processes. for esterification reaction the “produce more with less pollution” objective can be achieved by coupling reaction and separation in a so called integrated process. in this work a model for describing the esterification reaction of ethyl acetate in pervaporation mem...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...
