Numerous anti-inflammatory properties have been attributed to caffeic acid phenethyl ester (CAPE), an active component of propolis. NADPH oxidases are multienzymatic complexes involved in many inflammatory diseases. Here, we studied the importance of the CAPE hydrophobicity on cell-free antioxidant capacity, inhibition of the NADPH oxidase and hypochlorous acid production, and release of TNF-α ...

Fermentor-stabilized activated sludge from an industrial beverage bottling plant was grown on three different food sources: normal plant waste water, plant wastewater containing high sucrose concentrations, and a synthetic glucose-based feed stock. Surface charge, hydrophobicity, and exopolysaccharide composition were measured on the stabilized bacterial flocs. Cell surface charge was measured ...

neuroserpin, a member of the serine proteinase inhibitor (serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which may increase its neuroprotective effect. on the other hand, the oxidative modifications of the amin...

Present study documents the potential probiotic Lactobacillus isolated from indigenous fermented beverage Raabadi, consumed during summers in Haryana and Rajasthan regions of India. A total of five Raabadi samples were collected aseptically and 54 isolates were purified using MRS medium. All the isolates were assessed for tolerance to low pH and bile salts. It was observed that out of 54 only 2...

BACKGROUND Mucosal surface hydrophobicity is a key factor of the gastric acid defence barrier. In the colon, surface hydrophobicity is high but its biological function remains unexplored. AIMS To investigate the functional changes of the barrier due to removal of the surface active phospholipid layer by a detergent, or to reinforcement of the surface active phospholipid by local application o...

Growth rate control of adherent, sessile populations was achieved by the controlled perfusion of membrane-associated bacterial biofilms by the method of Gilbert et al. (P. Gilbert, D. G. Allison, D. J. Evans, P. S. Handley, and M. R. W. Brown, Appl. Environ. Microbiol. 55:1308-1311, 1989). Changes in cell surface hydrophobicity were evaluated with respect to growth rate for such sessile Escheri...

Physico-chemical properties of Aspergillus conidia rely on their outer cell-wall rodlet layer. In A. fumigatus and A. nidulans, the rodlet structure is due to an hydrophobin encoded by homologous rodA genes. To evaluate the role of the rodlet structure on the physico-chemical properties of conidia, we compared hydrophobicity, Lewis acid-base (i.e. electron donor/acceptor) characteristics and el...

The aim of this paper was to determine the adhesion of two physico-chemically characterized bacterial strains to a surface hydrophilic (CL A, water contact angle 57 degrees) and hydrophobic (CL B, water contact angle 106 degrees) hydrogel contact lens (CL) with and without an adsorbed tear film in a parallel plate flow chamber. Hydrophobicity (by water contact angles), charge (by particulate mi...

Quaternized polymers as ionomeric binders in the electrode enable operation of alternative fuel cells under high pH conditions or anhydrous to overcome challenges proton exchange membrane cells. Hydrophobicity ionomers derived from fluorine content is beneficial performance, but due synthetic difficulties, not many fluorinated quaternized have been reported with their influence on behavior thes...

The aim of the research was to perform a structural modelling analysis on amino acids hydrophobicity in order to identify, characterize and quantify the relationship between the structure and the property. A sample of twenty essential amino acids (alanine, arginine, asparagine, aspartate, cysteine, glutamine, glutamate, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine,...
