Properties of NADPH-cytochrome P-450 reductase purified from rabbit liver microsomes
(Elsevier, 1979-07)
NADPH-cytochrome P-450 reductase has been purified to electrophoretic homogeneity from rabbit liver microsomes by a procedure that may be used in conjunction with the isolation of the major forms of cytochrome P-450. The ...
Glycostatic effect of a diabetogenic non-growth-promoting pituitary polypeptide
(Elsevier, 1971-06)
1. 1. Treatment with a mg. of a non-growth-promoting bovine diabetogenic peptide or growth hormone in two divided doses, one at the beginning and one 7-9 hours later, to hypophysectomized rats during a 24-hour fast maintained ...
Enzymatic formation of hydroxy ceramides and comparison with enzymes forming nonhydroxy ceramides
(Elsevier, 1972-10)
Radioactive 2-hydroxystearic and cerebronic acids were converted to the coenzyme A thio esters, then tested for reactivity with -sphingosine. Microsomes from mouse brain were found to catalyze the formation of ceramides ...
Inhibition of sheep vesicular gland oxygenase by unsaturated fatty acids from skin of essential fatty acid deficient rats
(Elsevier, 1974-02-10)
Unsaturated fatty acids present in the lipids of essential fatty acid (EFA)-deficient rats were found to inhibit the oxygenase activity of sheep vesicular gland in an instantaneous, reversible manner. However, competitive ...
Synthetic inhibitors of glucocerebroside [beta]-glucosidase
(Elsevier, 1975-02)
The glucocerebrosidase of human placenta was studied with various potential inhibitors. Several compounds that resemble the lipoidal product of enzyme action, ceramide, proved to be excellent inhibitors, acting by mixed ...

Thyroid hormone action on mitochondria : III. Resolution of iodine-containing mitochondria and subfractions by zonal centrifugation
(Elsevier, 1972-06)
Mitochondria from the livers of normal rats and -thyroxine (LT4)-injected rats (5 [mu]g/g, 2 hr before killing) were studied by rate zonal centrifugation to detect early changes in physical properties and in composition. ...
Factors affecting anserine and carnosine levels in skeletal muscles of various animals
(Elsevier, 1976)
1. 1. Analytical procedures for anserine, carnosine and related histidine compounds in skeletal muscles are given.2. 2. The anserine/carnosine ratio in the skeletal muscles of the rat increases with age, cortisone injection ...
