Procion Green H-4G immobilized on a new IPN hydrogel membrane composed of poly(2-hydroxyethylmethacrylate)/chitosan: preparation and its application to the adsorption of lysozyme
(Elsevier Science Bv, 2002)
The adsorption of lysozyme has been investigated on the Procion Green H-4G immobilized novel poly(2-hydroxyethyl methacrylate)/chitosan) (pHEMA/chitosan; IPN) porous hydrogel membrane. The IPN membranes were prepared by ...
Entrapment of Lentinus sajor-caju into Ca-alginate gel beads for removal of Cd(II) ions from aqueous solution: preparation and biosorption kinetics analysis
(Elsevier Science Bv, 2002)
A white rot fungus species Lentinus sajor-caju biomass was entrapped into alginate gel via a liquid curing method in the presence of Ca(II) ions. The biosorption of cadmium(II) by the entrapped live and dead fungal biomass ...
Congo Red attached monosize poly(HEMA-co-MMA) microspheres for use in reversible enzyme immobilisation
(Elsevier Science Sa, 2002)
Monosize and non-porous poly(2-hydroxyethylmethacrylate-co-methylmethacrylate) (poly(HEMA-co-MMA)), microspheres were prepared by dispersion polymerisation of HEMA and MMA in an ethanol-water medium in the presence of an ...
Chondroitin sulfate-coated polyhydroxyethyl methacrylate membrane prevents adhesion in full-thickness tendon tears of rabbits
(W B Saunders Co-Elsevier Inc, 2002)
Polyhydroxyethyl methacrylate (pHEMA) membranes coated on one side with chondroitin sulfate (CS) were used to block adhesion physically and to reduce friction between healing flexor tendons and the surrounding tissue in ...
Crystal structure, spectroscopic studies and conformational analyses of 5-chloro-6-nitro-2-cyclohexylmethylbenzoxazole
(Elsevier Science Bv, 2002)
5-Chloro-6-nitro-2-cyclohexylmethylbenzoxazole (1) (C14H15O3N2Cl) has been studied by using an elemental analysis, IR, 5-Chloro-6-nitro-2-cyclohexylmethylbenzoxazole (1) ( H-1 NMR, X-ray analysis and AMI semi-empirical ...
Comparison of adsorption performances of metal-chelated polyamide hollow fibre membranes in lysozyme separation
(Elsevier Science Bv, 2002)
Commercially available microporous polyamide hollow fibres are modified by acid hydrolysis to activate the reactive groups and subsequently binding of the ligand, i.e. Cibacron Blue F3GA. Then the Cibacron Blue F3GA-derived ...
Prefabrication of a free peripheral nerve graft following implantation on an arteriovenous pedicle
(Thieme Medical Publ Inc, 2002)
Extensive nerve injuries frequently necessitate the use of long autografts, and sources of expendable donor nerves are limited. It is for these cases that nerve transplantation would have its greatest potential. However, ...
Covalent immobilization of lipase onto hydrophobic group incorporated poly(2-hydroxyethyl methacrylate) based hydrophilic membrane matrix
(Elsevier Sci Ltd, 2002)
In this study, a hydrophobic group containing monomer, 2-methacrylamidophenyalanine (MAPA) was prepared by using methacrylochloride and phenylalanine. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenlyalanine) ...
A case of pemphigus vulgaris possibly triggered by quinolones
(European Acad Dermatology & Venereology, 2002)
Pemphigus vulgaris is an autoimmune blistering disorder in which both genetic and environmental factors, mainly drugs, are thought to play a part in its aetiopathogenesis. Although some drugs that contain thiol groups, ...
A piezoelectric motor using two orthogonal bending modes of a hollow cylinder
(Ieee-Inst Electrical Electronics Engineers Inc, 2002)
This paper proposes a compact ultrasonic motor with low manufacturing costs, a simpler driving circuit, and scalability. The stator of the motor presented in this paper consists of a hollow metal cylinder, whose outside ...
