ZrTe5 and HfTe5: The heat capacity and derived thermophysical properties from 6 to 350 K
(Elsevier, 1989-07)
The heat capacities of ZrTe5 and HfTe5 have been measured by adiabatic shield calorimetry from 6 to 350 K on samples carefully shielded to minimize the contact between the sample and oxygen during all stages of preparation ...
Hydrogen peroxide oxidation catalyzed by chloride-depleted thylakoid membranes
(Elsevier, 1988-11-16)
Chloride-depleted thylakoid membranes which are unable to catalyze the oxidation of water can nonetheless catalyze the oxidation of hydrogen peroxide (Kelly, P. and Izawa, S. (1978) Biochim. Biophys. Acta 502, 198-210). ...
Reduction of ketones by sodium borohydride in the absence of protic solvents. Inter versus intramolecular mechanism
(Elsevier, 1982)
Acetone, acetophenone and benzophenone react with sodium borohydride in the absence of protic solvent to give the corresponding tetraalkoxyborates. In view of theseresults, the possibility of the 4-centre mechanism for ...
Improved high-performance liquid chromatographic assay for the quantification of 5-bromo-2'-deoxyuridine and 5-bromouracil in plasma
(Elsevier, 1988)
A sensitive and specific procedure using high-performance liquid chromatography (HPLC) was developed for the quantification of 5-bromo-2'-deoxyuridine (BUdR) and 5-bromouracil (BU) in plasma. BUdR and BU were first extracted ...
Fate of intravenously administered high-density lipoprotein labeled with radioiodinated cholesteryl oleate in normal and hypolipidemic rats
(Elsevier, 1983-03-01)
Radioiodinated cholesteryl oleate (125I-CO) was found to associate rapidly with plasma lipoproteins following intravenous administration to rats. The high-density lipoprotein (HDL) fraction was observed to contain the ...
FeAs: Heat capacity, enthalpy increments, other thermodynamic properties from 5 to 1350 K, and magnetic transition
(Elsevier, 1989-04)
The heat capacity of iron monoarsenide has been determined by adiabatic calorimetry from 5 to 1030 K and by drop calorimetry relative to 298.15 K over the range 875 to 1350 K. A small [lambda]-type transition is observed ...
Two-dimensional peptide mapping by reversed-phase column chromatography, applied to the sequence determination of cytochrome c from the wild type and a mutant of the butterfly, pieris brassicae
(Elsevier, 1983-08-26)
Two-dimensional peptide mapping has been very effective in the characterization of protein digests, particularly for the detection of small structural differences between homologous proteins. The classical thin-layer ...
[beta]-Endorphin suppression of acute morphine abstinence in morphine dependent monkeys: Effective given intraventricularly but ineffective given intravenously
(Elsevier, 1985-07)
Six female adult monkeys were made dependent upon morphine sulfate and were implanted with a chronic indwelling needle in the lateral ventricle of the brain for sterile intraventricular injections. Both [beta]-endorphin ...
Prodynorphin peptide immunocytochemistry in rhesus monkey brain
(Elsevier, 1985)
The present study describes the immunocytochemical distribution of peptides derived from the prodynorphin precursor in the brain of the rhesus monkey (Macaca mulatta). Animals were treated with colchicine (intracerebrove ...
Evidence that removal of an endogenous metal that stabilizes the untransformed glucocorticoid receptor in cytosol allows ligand-independent receptor transformation
(Elsevier, 1989)
Cytosol preparations contain an endogenous heat-stable factor which stabilizes the glucocorticoid receptor in its untransformed, non DNA-binding form. Elution of a partially purified preparation of this stabilizing factor ...
