The participation of pyridoxal phosphate, carnosine and calcium in the reversal of contraction in muscle fiber systems
(Elsevier, 1963-01)
A relaxing system requiring phosphocreatine as the relaxant may be restored to glycerinated psoas fibers by incubation in a reaction mixture containing pyridoxal phosphate, calcium, carnosine, magnesium, ATP, and sodium ...
Studies on the estimation of deoxyribonucleic acid and ribonucleic acid in rat brain
(Elsevier, 1963)
A method for the estimation of DNA and RNA in rat brain is described. The principal modifications of preexisting methods involve initial lipid extraction with chloroform-methanol and continuous stirring during alkaline ...
Rapid activation analysis of trace copper in tissue using 5.1-minute copper-66
(Elsevier, 1963-07)
Microgram amounts of copper have been analyzed by rapid activation analysis in rat kidney tissue. An 8-min radiochemical separation coupled with gamma-ray spectrometry permitted utilization of the 5.1-min copper-66 ...
Purification and properties of trehalase(s) from Neurospora
(Elsevier, 1963-09)
Trehalase has been obtained in crystalline form from the mycelium of Neurospora crassa. During elution from the first pass through a DEAE-cellulose column, two peaks with trehalase activity were obtained. When the first ...
Isotopic tracer studies on the biosynthesis of deoxyribose in the rat
(Elsevier, 1963)
The biosynthesis of deoxyribose, in vivo, was studied with NaH14CO3 as a tracer, in normal adult, starved adult, normal newborn, "thiamine-deficient" adult and "tumor bearing" rats and in Yoshida ascites-tumor cells. ...
