Both TNF receptors are required for direct TNF-mediated cytotoxicity in microvascular endothelial cells
(WILEY-VCH Verlag GmbH, 1998-11)
The conditions under which tumor necrosis factor-α (TNF) induces apoptosis in primary microvascular endothelial cells (MVEC) were investigated. In the absence of sensitizing agents, TNF induced apoptosis after 3 days of ...
Main-chain poly(arylene ether) phosphonium ionomers
(John Wiley & Sons, Ltd., 1998-10)
Poly(arylene ether) main-chain phosphonium ionomers were successfully synthesized and characterized. The reaction scheme involved first preparing the poly(arylene ether phosphine oxide) by a nucleophilic step or condensation ...
Decay-accelerating factor is a component of subendothelial extracellular matrix in vitro , and is augmented by activation of endothelial protein kinase C
(WILEY-VCH Verlag GmbH, 1998-03)
The vasculature is protected from complement activation by regulatory molecules expressed on endothelial cells. However, complement fixation also occurs on subendothelial extracellular matrix (ECM) in vitro, and is ...
Processing and properties of (Mo,Cr) oxycarbides from MOCVD
(John Wiley & Sons, Ltd., 1998-03)
A review of the coating kinetics of molybdenum and chromium oxycarbides and a study on the properties of deposited films are reported. Molybdenum carbonyl, chromium carbonyl and their mixture were used to prepare coatings ...
Trends in precursor design for conventional and aerosol-assisted CVD of high- T c superconductors
(John Wiley & Sons, Ltd., 1998-03)
Conventional MOCVD techniques require molecules displaying volatility and constant vapor pressure. Metal oxide precursors, i.e., β-diketonates, or classical or functionalized metal alkoxides are mostly solids. The various ...
Grafting of polymers onto a carbon black surface by the trapping of polymer radicals
(John Wiley & Sons, Ltd., 1998-10)
The grafting of polymers onto a carbon black surface based on the trapping of polymer radicals by polycondensed aromatic rings of the surface was investigated. It was found that polymer radicals formed by the thermal ...
Polyfunctional cubic silsesquioxanes as building blocks for organic/inorganic hybrids
(John Wiley & Sons, Ltd., 1998-10)
Cubic silsesquioxanes, [RSiO 1.5 ] x , potentially offer access to organic/inorganic hybrids wherein the exact shape, size and mechanical properties of the inorganic component are perfectly defined. Furthermore, by ...
Polymer-layered silicate nanocomposites: Synthesis, properties and applications
(John Wiley & Sons, Ltd., 1998-10)
Polymer nanocomposites, especially polymer-layered silicate (PLS) nanocomposites, represent a radical alternative to conventionally (macroscopically) filled polymers. Because of their nanometer-size dispersion, the ...
Open pore biodegradable matrices formed with gas foaming
(John Wiley & Sons, Inc., 1998-12-05)
Engineering tissues utilizing biodegradable polymer matrices is a promising approach to the treatment of a number of diseases. However, processing techniques utilized to fabricate these matrices typically involve organic ...
Stability of the contractile assembly and Ca 2+ - activated tension in adenovirus infected adult cardiac myocytes
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-04)
Adenovirus-mediated gene transfer into adult cardiac myocytes in primary culture is a potentially useful method to study the structure and function of the contractile apparatus. However, the consequences of adenovirus ...
