(Elsevier Science Bv, 2000)Magnetic poly(methylmethacrylate) microspheres (MPMMA) were prepared by the solvent evaporation method and a 6-carbon spacer-arm (i.e. hexamethylene diamine, HMDA) was covalently attached by the reaction of carbonyl groups ... -
Immobilization of glucose oxidase and urease in hydrogel matrices
(Scientific Technical Research Council Turkey, 1997)Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, ... -
Immobilization of polyphenol oxidase on carboxymethylcellulose hydrogel beads: preparation and characterization
(John Wiley & Sons Ltd, 2000)Carboxymethylcellulose (CMC) beads were prepared by a liquid curing method in the presence of trivalent ferric ions, and epicholorohydrin was covalently attached to the CMC beads. Polyphenol oxidase (PPO) was then covalently ... -
Immunohistochemical Expressions of the Antimicrobial Peptides (hBD-3 and hCAP-18/LL-37) in Colon, Stomach and Lung Adenocarcinomas
(Akad Doktorlar Yayinevi, 2015)This study investigated the immunohistochemical staining characteristics of human beta defensin-3 (hBD-3) and human cationic antimicrobial peptide-18/cathelicidin (hCAP-18/LL-37) in colon, stomach and lung adenocarcinomas ... -
In vitro cadmium removal from human serum by Cibacron Blue F3GA-thionein-complex conjugated affinity membranes
(John Wiley & Sons Ltd, 2000)A new membrane affinity biosorbent carrying thionein has been developed for selective removal of cadmium ions from human serum. Microporous poly(2-hydroxyethyl methacrylate) (pHEMA) membranes were prepared by photopolymerization ... -
In-vitro studies of enteric coated diclofenac sodium-carboxymethylcellulose microspheres
(Taylor & Francis Ltd, 1996)Microspheres containing diclofenac sodium (DS) were prepared using carboxymethylcellulose (CMC) as the main support material (1.0, 2.0, 3.0% (w/v)) and aluminium chloride as the crosslinker. Drug to polymer ratios of 1:1, ... -
Induction of triacylglycerol production in Chlamydomonas reinhardtii: Comparative analysis of different element regimes
(Elsevier Sci Ltd, 2014)In this study, impacts of different element absence (nitrogen, sulfur, phosphorus and magnesium) and supplementation (nitrogen and zinc) on element uptake and triacylglycerol production was followed in wild type Chlamydomonas ... -
Invertase immobilized on spacer-arm attached poly(hydroxyethyl methacrylate) membrane: Preparation and properties
(John Wiley & Sons Inc, 2000)Microporous poly(2-hydroxyethyl methacrylate) (pHEMA) membrane was prepared by UV-initiated photopolymerization. The spacer arm (i.e., hexamethylene diamine) was attached covalently and then invertase was immobilized by ... -
