VM-26 in colorectal carcinoma: A Southwest Oncology Group study
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-02)
In this multi-institutional phase II study, VM-26 or Teniposide was administered to forty-two patients with advanced colorectal cancer. Patients were initially treated at 60 mg/M 2 daily for 5 days with dose adjustments ...
Differential dependence on protein kinase C of arachidonic acid metabolism stimulated by hydrogen peroxide and by zymosan in the alveolar macrophage
(Elsevier, 1990-11-12)
The dependence on protein kinase C (PKC) of arachidonic acid (AA) metabolism stimulated by the biologically important oxidant H2O2 as compared to zymosan particles, was investigated in the rat alveolar macrophage. The PKC ...
Rapid flow-injection sandwich-type immunoassays of proteins using an immobilized antibody reactor and adenosine deaminase-antibody conjugates
(Elsevier, 1990)
A rapid flow-injection sandwich enzyme immunoassay suitable for the direct determination of proteins in biological samples is described. The proposed system utilizes highly active adenosine deaminase--antibody conjugates ...
High resolution laser spectroscopy of relaxation and the excitation lineshape of excitons in GaAs quantum well structures
(Elsevier, 1990-04-01)
A new class of measurements on GaAs quantum well structures based on frequency domain nonlinear laser spectroscopy is described. Room temperature measurements of the excitation relaxation show an interference effect in the ...
Synthesis and peptide bond orientation in tetrapeptides containing L -azetidine-2-carboxylic acid and L -proline
(Wiley Subscription Services, Inc., A Wiley Company, 1990)
The role of the amino acid proline in influencing the secondary and tertiary structure of proteins and polypeptides has been an area of active study for many years. We have investigated this problem by incorporating the ...
Properties and device applications of deep quantum well resonant tunneling structures
(Elsevier, 1990-04-01)
A self-consistent quantum mechanical simulation is used to study the effects of doping, spacer layers, barrier height, barrier width and well doping on the bound state and bound state charge in a deep quantum well resonant ...
Synthesis and reactivity of rhodium(I) and iridium(I) complexes of the dianions of 2,3-pyrazinedicarboxylic and 2,5-pyrazinedicarboxylic acid
(Elsevier, 1990-03-27)
Rhodium and iridium complexes of the title ligands have been prepared containing cyclooctadiene, carbonyl, phosphine and phosphite ancillary ligands. The complexes are mononuclear or dinuclear depending on the method of ...
Epitaxial growth and characterization of GaAs/Al/GaAs heterostructures
(Elsevier, 1990-04-01)
We report on transmission electron microscopy, secondary ion mass spectroscopy, X-ray and Raman scattering studies of GaAs/Al/GaAs heterostructures grown by migration enhanced epitaxy.
Phase II evaluation of mitoxantrone in advanced pancreatic carcinoma: A Southwest Oncology Group study
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-02)
Patient with advanced adenocarcinoma of the pancreas and no prior chemotherapy were treated on a Phase II trial of mitoxantrone. Doses were adjusted for hepatic dysfunction as defined by bilirubin. Twenty-four patients ...
The emission of X-rays by fission fragments
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1990-09)
Approximately 5% of the γ-ray transitions in fission fragments are internally converted, giving rise to X-rays. X-ray energies are characteristic of Z, but yields depend strongly and not smoothly on Z and A of the fragments ...
