A simple and rapid microextraction procedure based on the application of magnetic nanoparticles and hydrophobic 1-Hexylpyridinium hexafluorophosphate [Hpy][PF6] ionic liquid (IL) was applied to trace determination of gatifloxacin. A mixture of [Hpy][PF6] and magnetic nanoparticles was injected into the sample solution containing the analyse of interest and a cloudy solution was forme...
PURPOSE To determine the in vitro effectiveness of Plantago major extract, along with two of its active components, aucubin and baicalein, on the inhibition of Candida albicans growth, biofilm formation, metabolic activity, and cell surface hydrophobicity. MATERIALS AND METHODS Twofold dilutions of P. major, aucubin, and baicalein were used to determine the minimum inhibitory concentration (M...
Objective The aim of this study was to investigate the prevalence of isolated Candida albicans from periodontal endodontic lesions in diabetic and normoglycemic patients, and the fungi's virulence in different atmospheric conditions. Material and Methods A case-control study was conducted on 15 patients with type 2 diabetes mellitus (G1) and 15 non-diabetics (G2) with periodontal endodontic l...
Hedrick, L. R. (Illinois Institute of Technology, Chicago), and C. J. Feren. Effect of cations upon hydrophobicity of yeasts grown in amino acid media. J. Bacteriol. 86:1288-1294. 1963.-Cells of four species of Hansenula, namely, H. holstii Y2154, H. subpelliculosa Y1683 and Y1542, and H. anomala Y365, were cultured for 3 days in a glucose-salts medium with one amino acid or (NH(4))(2)SO(4) as ...
Owing to the influence of nanomaterials on biomacromolecular behavior, their potential applications are rapidly gaining attention. Based on atomistic molecular dynamics simulation studies we have recently reported that the full-length Aβ peptide, whose self-assembly is associated with Alzheimer's disease, adsorbs rapidly on single-walled carbon nanotubes, thereby losing its natural propensity t...
Fermentor-stabilized activated sludge from an industrial beverage bottling plant was grown on three different food sources: normal plant wastewater, 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 b...
UNLABELLED The aim of the present paper is to evaluate the effect of the high molecular weight chitosan (HMWC) and of sodium alginate (NaAL) on surface hydrophobicity of Candida albicans and on adhesion of the yeast to epithelial cells and fibroblasts of different proceeding. For this study, a collection strain and seven isolates of C. albicans from saliva (patients with denture stomatitis) wer...
The Hansch equation is a key mathematical relationship and a conceptual guiding principle (QSAR) in the practice of modern medicinal chemistry. Recent years have apparently witnessed a debate on the utility of QSAR, hence it seems opportune to explore its fundamental origins. The Hansch equation leads to a parabolic relationship between drug activity and hydrophobicity. Currently, this is expla...
