Retronasal but not oral-cavity-only identification of "purely olfactory" odorants.

Aðeins skráðir notendur geta þýtt greinar

Skráðu þig / skráðu þig

Identifications of 5 odorants selected to be nontrigeminal stimuli were compared using retronasal and oral-cavity-only (OCO) air-phase presentations, with OCO produced by both exhalation through the mouth and a nose clip that closed the nostrils. Nine identifiers were available on each trial; 1 or 2

Approaching polymetallic 'assemblies of assemblies' using ligands with multiple functionality--novel Mn10M2 (M = alkali metal) chains with 'ionophoric' end cavities.

A tri-functional ligand with hydrazone, oxime and o-vanillin subunits uses separate encoded coordination instructions to create a novel extended spin-coupled cluster where the hydazone oxygen and oxime groups of three ligands combine to create bridges linking ten Mn ions together, leaving organized

The purely olfactory odorants coumarin, octanoic acid, phenylethyl alcohol, and vanillin had been found to be consistently identified when presented retronasally but could not be identified when presented oral-cavity only (OCO). However, OCO discrimination of these odorants was not tested.

Combination of computational methods, adsorption isotherms and selectivity tests for the conception of a mixed non-covalent-semi-covalent molecularly imprinted polymer of vanillin.

Capsaicin causes a burning or spicy sensation when this vanilloid compound comes in contact with trigeminal neurons of the tongue. This compound has low solubility in water, which presents difficulties in examining the psychophysical properties of capsaicin by standard aqueous chemosensory tests.

OBJECTIVE To evaluate the anticancer activity of vanillin semicarbazone (VSC) against Ehrlich ascites carcinoma (EAC) cells in Swiss albino mice. METHODS The compound VSC at three doses (5, 7.5 and 10 mg/kg i.p.) was administered into the intraperitoneal cavity of the EAC inoculated mice to observe

Selective Sequestration of Aromatics from Aqueous Mixtures with Sugars by Hydrophobic Molecular Calixarene Cavities Grafted on Silica.

Skráðu þig / skráðu þig

The separation of aromatic contaminants from sugar-aromatic aqueous mixtures is required in second-generation biorefineries because aromatic compounds deactivate (bio)catalysts typically involved in upgrading lignocellulosic biomass to fuels and chemicals. This separation remains challenging,

Vanillin has previously been studied clinically as an antisickling agent to treat sickle-cell disease. In vitro investigations with pyridyl derivatives of vanillin, including INN-312 and INN-298, showed as much as a 90-fold increase in antisickling activity compared with vanillin. The compounds

Vanillin, a food additive, has been evaluated as a potential agent to treat sickle cell anemia. Earlier studies indicated that vanillin had moderate antisickling activity when compared with other aldehydes. We have determined by high performance liquid chromatography that vanillin reacts covalently

Cryptophane-E was synthesized from vanillin by a three-step method, and its absorption and fluorescence spectroscopic properties were determined. Two absorption bands at about 245-260 and 280-290 nm were observed for cryptophane-E and the fluorescence emission maxima were at 320-330 nm depending on
