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 ...
Glutamine synthetase : III. Factors controlling its activity in the developing rat
(Elsevier, 1964)
The developmental changes in glutamine synthetase activity in rat liver and brain have been studied and shown to be different in the two tissues. The liver enzyme exhibited a fall in activity after birth, followed by a ...
Matrix elements for configuration d5 in weak octahedral field using Racah methods
(Elsevier, 1968-10)
The matrix elements of the spin--orbit and crystal field interactions in a weak-cubic-field scheme have been calculated for the d5 configuration. These matrices will be of use in the analysis of spectra of d5 complexes ...
Tumor localizing agents V. Radioiodinated pregnanes
(Elsevier, 1968-06)
Previous studies with progesterone-4-14C suggested that a radioiodinated analog might be useful for photoscanning the adrenal gland and associated tumors. 21-Iodoprogesterone was prepared by conversion of deoxycorticosterone ...
Autonomic and psychic effects of yohimbine hydrochloride
(Springer-Verlag, 1961-03)
Yohimbine in a dose of 0.5 mg/kg has been given to 51 male mental hospital subjects and nine normal volunteers.
Sulfurylation of estradiol-17B by extracts of ovary, corpus luteum, testis and adrenal cortex1
(Elsevier, 1965-01)
Soluble enzyme preparations from bovine ovary, corpus luteum and adrenal cortex and from rat testis sulfurylated estradiol-17[beta] in the presence of ATP and Mg++. Two major products were tentatively identified by ...
The vibration-rotation energies of tetrahedral XY4 molecules : Part I. Theory of spherical top molecules
(Elsevier, 1961)
The theory of vibration-rotational perturbations in tetrahedral XY4 molecules has been reexamined in the light of the modern theory of angular momentum coupling. It is shown that, even to third order of approximation, the ...
