Potentiometric enzyme channelling immunosensor for proteins
(Elsevier, 1991)
A potentiometric immunosensor for the detection of human IgG has been developed using an asymmetric, ion-selective membrane with immobilized adenosine deaminase and IgG. A protein A-alkaline phosphatase conjugate binds to ...
Retardation of calcification of bovine pericardium used in bioprosthetic heart valves by phosphocitrate and a synthetic analogue
(Elsevier, 1988-09)
The purpose of this study was to determine if phosphocitrate (PC), a naturally occurring inhibitor of calcification, and its synthetic analogue, N-sulpho-2-amino tricarballylate (SAT), administered either by daily injection ...
Preparation of dietnylaminoetnyl hollow fibres for high-flow liquid chromatography
(Elsevier, 1990-11)
A novel anion-exchange column for fast-flow liquid chromatography was developed. The column was prepared by immobilizing diethylaminoethyl groups on to the inner walls of regenerated cellulose hollow fibres. A detailed ...
Prevention of calcification of glutaraldehyde pretreated bovine pericardium through controlled release polymeric implants: studies of Fe3+, Al3+, protamine sulphate and levamisole
(Elsevier, 1990-11)
Calcification is the principal cause of the clinical failure of bioprosthetic heart valves fabricated from glutaraldehyde pretreated porcine aortic valves or bovine pericardium. The present study investigated controlled-release ...
Transient measurement of dissolved oxygen using membrane electrodes
(Elsevier, 1989)
Transient mode dissolved oxygen measurement has been studied using a specially constructed galvanic membrane electrode controlled by a microcomputer. A four-layer diffusion model was developed to describe the dynamic ...
Hydroxyapatite implants with designed internal architecture
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-06)
Porous hydroxyapatite (HA) has been used as a bone graft material in the clinics for decades. Traditionally, the pores in these HAs are either obtained from the coralline exoskeletal patterns or from the embedded organic ...
Successful antidote of multiple lethal infections using sustained delivery of difluoromethylornithine by means of ceramic drug delivery devices
(Elsevier, 1994)
The objectives of this study were (1) to cure multiple infections of trypanosorniasis in rats by the sustained release of DEMO from biodegradable tricalcium phosphate (TCP) and aluminum-calcium-phosphorous oxide (ALCAP) ...
Effective anisotropic elastic constants of bimaterial interphases: comparison between experimental and analytical techniques
(Kluwer Academic Publishers; Springer Science+Business Media, 1996-02)
The effective elastic constants of a bimaterial composite were experimentally measured with the goal of validating the numerical predications of these constants made by homogenization theory. Secondly, solutions predicted ...
Polymer membrane-based ion-, gas- and bio-selective potentiometric sensors
(Elsevier, 1993)
Recent progress in the design of new polymer membrane-based potentiometric ion-, gas- and bio-selective electrodes in chemistry laboratories at the University of Michigan (Ann Arbor) is reviewed. Emphasis is placed on ...
