Heat capacity and thermodynamic properties of synthetic heazlewoodite, Ni3S2, and of the high-temperature phase Ni3±xS2
(Elsevier, 1991-01)
The heat capacity of synthetic heazlewoodite (Ni3S2) was measured over the temperature range 5 K to 350 K by equilibrium adiabatic calorimetry and compared with earlier results. High-temperature results on this phase and ...
Poly- L -lysine amplification of protamine immobilization and heparin adsorption
(John Wiley & Sons, Inc., 1998-11)
We previously reported the development of a cellulose fiber based blood filter device containing immobilized protamine (termed protamine filter) that could be used to control both heparin- and protamine-induced complications ...
Effects of single and repeated electroconvulsive therapy sessions on plasma ACTH, prolactin, growth hormone and cortisol concentrations
(Elsevier, 1991)
To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately ...
1,2-Addition of dimethyl(phenyl)silyllithium to cyclic [alpha],[beta]-unsaturated ketones and regiospecific generation of cyclic silyl enol ethers through brook rearrangement of the 1,2-addition products
(Elsevier, 1990)
A highly convenient two-step sequence for the regiospecific synthesis of cyclic silyl enol ethers has been developed involving the 1,2-addition of dimethyl(phenyl)silyllithium to cyclic [alpha],[beta]-unsaturated ketones ...
Preparation and properties of silicon-containing polymer hybrids from 3-methacryloxypropyltrimethoxysilane
(John Wiley & Sons, Ltd., 1998-10)
The preparation of organic–inorganic polymer hybrids consisting of carbon–carbon and siloxane chains was investigated by radical polymerization of 3-methacryloxypropyltrimethoxysilane (MAS) followed by acid-catalyzed ...
Incorporation of alkylthiol chains at C-5 of deoxyuridine
(Elsevier, 1993-08-27)
A series of alkylthiol-tether homologs at C-5 of 2'-deoxyuridine have been synthesized and incorporated into DNA oligomers through solid-phase DNA phosphoramidite synthesis. DNA-ligand disulfide crosslinks have been initially ...
Site-specific delivery of ethanehydroxy diphosphonate from refillable polyurethane reservoirs to inhibit bioprosthetic tissue calcification
(Elsevier, 1993-06)
Calcification (CALC) is the most frequent cause for the failure of bioprosthetic heart valves fabricated from glutaraldehyde-pretreated porcine aortic valve, and contributes to the failure of glutaraldehyde pretreated ...
Inhibition of fludarabine metabolism by arabinosylcytosine during therapy
(Springer-Verlag, 1992-05)
The active 5′-triphosphate of arabinosyl-2-fluoroadenine (F-ara-ATP) increases the anabolism of arabinosylcytosine (ara-C), whereas ara-C 5′-triphosphate inhibits the phosphorylation of arabinosyl-2-fluoroadenine (F-ara-A) ...
Regulatory mechanisms underlying T cell integrin receptor function
(Elsevier, 1993-08)
Adhesion molecules allow lymphocytes to interact with and respond to the extracellular environment. Since these interactions must be essentially transient in nature, the function of lymphocyte adhesion molecules must be ...
Isolation and Immunocytochemical Characterization of Three Tachykinin-Related Peptides from the Mosquito, Culex salinarius
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-02)
Three myotropic peptides belonging to the Arg-amide insect tachykinin family were isolated from whole-body extracts of the mosquito, Culex salinarius . The peptides, APSGFMGMR-NH 2 , APYGFTGMR-NH 2 and APSGFFGMR-NH 2 ...
