DNA-binding and non-DNA-binding forms of the transformed glucocorticoid receptor
(Elsevier, 1992-03)
In this work we have probed the mechanism responsible for two non-DNA-binding states of the mouse glucocorticoid receptor. In the first case, transformed receptors were treated with hydrogen peroxide. It is known that ...
The effect of spacer length on the polymerization of diacetylenes in sams on gold surfaces
(WILEY‐VCH Verlag GmbH & Co. KGaA, 1999-08)
The influence of the molecular architecture of diacetylene disulfides on the structure and polymerizability of self assembled monolayers on gold was investigated. The position of the diacetylene group was varied systematically ...
Assay of human plasma cortisone by liquid chromatography: normal plasma concentrations (between 8 and 10 a.m.) of cortisone and corticosterone
(Elsevier, 1993-04-02)
A high-performance liquid chromatographic method using ultraviolet detection to quantitate human plasma concentrations of cortisone simultaneously with cortisol and corticosterone is described. The method is based on the ...
Porous poly( L -lactic acid)/apatite composites created by biomimetic process
(John Wiley & Sons, Inc., 1999-06-15)
Highly porous poly( L -lactic acid)/apatite composites were prepared through in situ formation of carbonated apatite onto poly( L -lactic acid) foams in a simulated body fluid. The highly porous polymer foams (up to 95% ...
A Continuous Spectrophotometric and Fluorometric Assay for Protein Tyrosine Phosphatase Using Phosphotyrosine-Containing Peptides
(Elsevier, 1993-05-15)
Two continuous assays for protein tyrosine phosphatases (PTPases) have been developed using phosphotyrosine containing peptide substrates. These assays are based on the marked differences in the spectra of the peptide ...
Vibrational analysis of 2,3,4-trichloropentanes
(Elsevier, 1990)
One meso form and the racemic isomer of 2,3,4-trichloropentane have been synthesized, and their infrared and Raman spectra analysed on the basis of a general force field refined for multiply-chlorinated hydrocarbons. ...
Poly(Α-hydroxyl acids)/hydroxyapatite porous composites for bone-tissue engineering. I. Preparation and morphology
(John Wiley & Sons, Inc., 1999-03-15)
Tissue engineering has shown great promise for creating biological alternatives for implants. In this approach, scaffolding plays a pivotal role. Hydroxyapatite mimics the natural bone mineral and has shown good bone-bonding ...
Synthesis of high-affinity, hydrophobic monosaccharide derivatives and study of their interaction with concanavalin A, the pea, the lentil, and fava bean lectins
(Elsevier, 1992-12)
Concanavalin A (Con A) and agglutinins from the pea (PSA), lentil (LCH), and fava bean (VFA) constitute a group of -mannose/-glucose binding legume lectins. In addition to their sugar binding specificity, these lectins ...
IGF receptor function and regulation in autocrine human neuroblastoma cell growth
(Elsevier, 1993-10-20)
Insulin-like growth factor-II (IGF-II) and its receptors (type I and II IGF receptors) are expressed in the nervous system in a tissue and developmentally specific manner. We have previously shown that SH-SY5Y human ...
Continuous medium perfusion leads to long-term cell viability and oxygen production in high-density photobioreactors
(Kluwer Academic Publishers; Chapman & Hall, London ; Springer Science+Business Media, 1995-11)
A light-emitting diode-based photobioreactor (LED-based PBR) operated in a continuous perfusion mode with a perfusion rate of 3 to 6 reactor volumes a day supports high-density algal cultures, of cell concentrations up to ...
