Role of alcohol P-450-oxygenase (APO) in microsomal ethanol oxidation
(Elsevier, 1985)
The form of liver microsomal cytochrome P-450 induced by chronic administration of ethanol to rabbits, designated as P-450 or P-450 isozyme 3a, has been purified to homogeneity as judged by several criteria, including NH2- ...
Photodiode array ultraviolet spectrophotometric profiling of carboxylic acids in physiological fluids
(Elsevier, 1985)
In this paper the use of a computer-controlled photodiode array spectrophotometric detector for the high-performance liquid chromatographic (HPLC) profiling of carboxylic acids in physiological fluids is reported. The ...
Thermodynamics of thallium alkanoates I. Heat capacity and thermodynamic functions of thallium(I) n-hexanoate
(Elsevier, 1985-05)
The sub-ambient heat capacity of thallium(I) n-hexanoate is characterized by transitions at 203.5 and 208.3 K which show Cp, m/R maxima of about 400 and 2500 and ([Delta]Sm/R)'s of 1.03 and 1.07. Both appear to be essentially ...
Indirect determination of thallium by differential-pulse polarography
(Elsevier, 1985-06)
The method is based on the separation ofTl(I) as Tl2HPMo12O40, stripping of the molybdate, and measurement of the peak current in differential-pulse polarography of the molybdenum. The calibration graph is linear over the ...
Free-jet spectra and structure of o-, m- and p-dihydroxybenzenes
(Elsevier, 1985-11-15)
Analysis of the free-jet spectra of hydroquinone (para), catechol (ortho) and resorcinol (meta) shows the presence of multiple origins in each molecular spectrum which are interpreted as belonging to separate structural isomers.
Free radicals in ischemic myocardial injury
(Elsevier, 1985)
Myrocardial ischemia causes release of chemotactic factors, migration of neutrophils, peroxidation of lipids, and depletion of free radical scavengers. The invading neutrophils may injure the myrocardial vasculature and ...
Evidence for two cyclic photophosphorylation reactions concurrent with ferredoxin-catalyzed non-cyclic electron transport
(Elsevier, 1985-06-26)
Addition of ferredoxin to isolated spinach chloroplast thylakoid membranes reconstitutes phosphorylating electron transfer characterized by elevated P/O ratios (1.6). When oxygen is the terminal electron acceptor for reduced ...
High-performance thin-layer chromatography assay for epoxide hydrolase activity and the determination of phenoxypropane-1,2-diols
(Elsevier, 1985)
A simple, rapid and sensitive high-performance thin-layer chromatographic assay for the determination of epoxide hydrolase activity in rat liver homogenates is described. It is extended to the determination of a series of ...
Thermodynamics of uranium intermetallic compounds I. Heat capacities of URu3 and URh3 from 5 to 850 K
(Elsevier, 1985-11)
Heat capacities of carefully characterized samples of URu3 and URh3 were measured by adiabatic calorimetry from 5 to 350 K by adiabatic calorimetry and from 300 to 850 K by enthalpy-increment drop calorimetry. Values for ...
Heparin inhibition of ferredoxin-NADP reductase in chloroplast thylakoid membranes
(Elsevier, 1985-02-01)
Heparin, an anionic polysaccharide, inhibited the ferredoxin-catalyzed reduction of NADP in spinach chloroplast thylakoid membranes. Under the same conditions of assay, heparin did not interfere markedly with photoreduction ...
