In vitro synergistic, antagonistic, and duration of exposure effects of metal cations on eukaryotic cells
(John Wiley & Sons, Inc., 1992-10)
Effects of duration of exposure of single metal cations (Ag +1 , Cd +2 , Cu +2 , Ga +3 , Ni +2 , and Zn +2 ) on 3H-thymidine (3H-Tdr) incorporation and 3-[4,5-dimethylthiazol-2yl-]-2,5-diphenyl tetrazolium bromide-formazan ...
Controlled dosing of nicotine via an I ntranasal N icotine A erosol D elivery D evice (INADD)
(Springer-Verlag, 1992-09)
The present report describes an I ntranasal N icotine A erosol D elivery D evice (INADD) employing an artist's airbrush as aerosolizer and precise, electromechanical control of spray duration. It was designed for the ...
Multicenter phase II trial of brequinar sodium in patients with advanced squamous-cell carcinoma of the head and neck
(Springer-Verlag, 1992-03)
A total of 19 patients with advanced squamous-cell carcinoma of the head and neck who had not previously been exposed to chemotherapy were treated with brequinar sodium as first-line chemotherapy. Brequinar was given ...
Infrared spectra and structures of hexamethyl- and hexaethylhydrodiborate ions, H[B(CH3)3]-2 and H[B(C2H5)3]-2, in glycol ether solution
(Elsevier, 1992-02)
Infrared spectra have been obtained of lithium hexamethyl- and hexaethylhydrodiborates and deuterodiborates in diglyme solution at temperatures near 0[deg]C. Assignments are proposed and arguments are presented in support ...
A potential animal model for studying CF heterozygote advantage: Genetic variation in theophylline-inducible colonic chloride currents among inbred strains of mice
(Elsevier, 1992-02)
We have used Ussing chambers to measure chloride secretion by colonic segments (mucosa, muscularis, and serosa) from various inbred strains of mice. We found lower theophylline-induced Cl- secretion in the DBA/2J than in ...
Characterization and hydrodesulfurization activity studies of unpromoted molybdenum sulfides prepared by elemental solid state reaction
(Elsevier, 1992-10)
Solid state reactions of elemental molybdenum and sulfur were used to synthesize unpromoted, model HDS catalysts. The samples studied had synthesis stoichiometries of MoS2 MoS1.95, and MoS1.975. Catalytic activity for the ...
FTIR study of bimetallic Pt-Sn/Al2O3 catalysts
(Elsevier, 1992-12)
A series of Pt-Sn/Al2O3 catalysts supported on Degussa nonporous alumina were characterized by infrared spectroscopy of adsorbed CO. The nominal platinum loading was kept constant in the catalysts at 1 wt% and the nominal ...
Chemisorption studies of promoted solid-state HDS catalysts
(Elsevier, 1992-06)
Oxygen pulse chemisorption measurements were made on a series of model HDS catalysts synthesized from solid-state reactions of elemental starting materials. Three different promoter atoms having the following catalyst ...
Serial studies of autologous antibody reactivity to squamous cell carcinoma of the head and neck
(Springer-Verlag, 1992-09)
In previous studies we evaluated the incidence and specificity of autologous antibody reactivity against squamous cell carcinoma of the head and neck (SCCHN). We were able to demonstrate that autologous antibody reactivity ...
Identification of new markers in Xp21 between DXS28 (C7) and DMD
(Elsevier, 1992-08)
Characterization of Xp21 distal to Duchenne muscular dystrophy (DMD) in the region containing the genes for adrenal hypoplasia congenita (AHC) and glycerol kinase deficiency (GKD) has been limited due to a paucity of probes. ...
