Barriers to US industrial biotechnology research consortia
(Elsevier, 1989-09)
In 1986-1987, the research directors of major and medium-sized US biotechnology companies agreed on the wisdom of developing cooperative research arrangements in protein engineering, bioprocess and large-scale animal cell ...
Standard molar Gibbs free energy of formation for Cu2O: high-resolution electrochemical measurements from 900 to 1300 K
(Elsevier, 1989-04)
Oxygen-concentration cells with zirconia solid electrolytes have been used to make equilibrium measurements of the standard molar Gibbs free energy of formation for copper(I) oxide, [Delta]fGmo(Cu2O), over the temperature ...
Prediction of thioguanine-induced cytotoxicity by dual-parameter flow cytometric analysis
(Springer-Verlag, 1989-10)
A method is presented for the quantitative analysis of delayed cytokinetic effects resulting from the treatment of L1210 cells with 6-thioguanine (TG). By using dual-parameter (DNA/protein) flow cytometry, we could observe ...
16, 16 Dimethyl prostaglandin E2 decreases the formation of collagen in fibrotic rat liver slices
(Elsevier, 1989-04)
The effect of 16, 16 dimethyl prostaglandin E2 (DMPG) on fibrogenesis was studied in slices from normal and fibrotic rat liver. Rats received a cirrhogenic diet for seven months; supplemented controls received a diet with ...
Characteristics of an adenosine A1 binding site in human placental membranes
(Elsevier, 1989-01)
Binding sites were solubilized from human placental membrane using 1.5% sodium cholate and were assayed using polyethylene glycol precipitation. These soluble binding sites had properties of an adenosine A1 binding site. ...
Synthesis of the optically active [alpha]-nucleic acid base substituted propanoic acids
(Elsevier, 1989)
The (R)-2-(adenin-9-yl)propanoic acid was prepared from adenine and (S)-ethyl lactate by using the triphenyl phosphine-diethyl azodicarboxylate system. The (R)-2-(thymin-1-yl)-propanoic acid, (R)-2-(cytosin-1-yl)propanoic ...
Acute effects of high-dose thyrotropin releasing hormone infusions in Alzheimer's disease
(Springer-Verlag, 1989-07)
Thyrotropin releasing hormone (TRH) was administered intravenously to ten patients with Alzheimer's Disease (AD) in a high-dose paradigm, thought to maximize central nervous system effects and potentially produce facilitation ...
Solid state synthesis and characterization of model hydrodesulfurization catalysts
(Elsevier, 1989-10)
Solid-state reactions of elemental sulfur with metallic cobalt and molybdenum powders were used to synthesize model catalysts for hydrodesulfurization (HDS). The resulting materials had a general stoichiometry of Co2xMo1-xS2 ...
