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...
