Bayramoglu, G; Yilmaz, M; Arica, MY (Elsevier Science Sa, 2003)A composite membrane from 2-hydroxyethyl methacrylate (HEMA) and poly(hydroxyethyl methacrylate)/chitosan (pHEMA/chitosan) was synthesized via UV initiated photo-polymerization in the presence of an initiator alpha,alpha ... -
Affinity membrane chromatography: relationship of dye-ligand type to surface polarity and their effect on lysozyme separation and purification
Arica, MY; Yilmaz, M; Yalcin, E; Bayramoglu, G (Elsevier, 2004)Two different dye-ligands, i.e. Procion Brown MX-5BR (RB-10) and Procion Green H-4G (RG-5) were immobilised onto poly(2-hydroxyethylmethacrylate) (pHEMA) membranes. The polarities of the affinity membranes were determined ... -
Biosorption of Hg2+, Cd2+, and Zn2+ by Ca-alginate and immobilized wood-rotting fungus Funalia trogii
Arica, MY; Bayramoglu, G; Yilmaz, M; Bektas, S; Genc, O (Elsevier, 2004)Funalia trogii biomass was immobilized in Ca-alginate gel beads. The live and beat inactivated immobilized forms were used for the biosorption of Hg2+, Cd2+ and Zn2+ ions by using plain Ca-alginate gel beads as a control ... -

Yilmaz, M; Bukan, N; Ayvaz, G; Karakoc, A; Toruner, F; Cakir, N; Arslan, M (Oxford Univ Press, 2005)BACKGOUND: Oxidative stress and hyperhomocysteinaemia are risk factors for cardiovascular diseases. The aim of this study was to assess the effects of rosiglitazone and metformin on cardiovascular disease risk factors such ... -
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
Bayramoglu, G; Yilmaz, M; Arica, MY (Elsevier, 2004)We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ... -
Glucose intolerance, insulin resistance and cardiovascular risk factors in first degree relatives of women with polycystic ovary syndrome
BACKGROUND: The aim of the present study was to evaluate insulin resistance (IR), glucose tolerance status and cardiovascular risk factors in first degree relatives of patients with polycystic ovary syndrome (PCOS). METHODS: ... -
