Structural organization of the oxidizing side of photosystem II. Exogenous reductants reduce and destroy the Mn-complex in photosystems II membranes depleted of the 17 and 23 kDa polypeptides
(Elsevier, 1984-12-18)
Removal of 23 and 17 kDa water-soluble polypeptides from PS II membranes causes a marked decrease in oxygen-evolution activity, exposes the oxidizing side of PS II to exogenous reductants (Ghanotakis, D.F., Babcock, G.T. ...
Spectroscopic and scattering investigation of isopoly-molybdate and tungstate solutions
(Elsevier, 1984)
Detailed spectroscopic and scattering investigations of isopoly-molybdate and -tungstate solutions as a function of concentration and pH were made. From scattering results the apparent molecular weights were determined as ...
Paradoxical effects of glucocorticoids on regulation of plasminogen activator activity : Mediation by glucocorticoid receptors
(Elsevier, 1984-02)
Dexamethasone, a synthetic glucocorticoid, decreases the plasminogen activator (PA) activity of HTC rat hepatoma cells in tissue culture. Paradoxically, dexamethasone enhances the cyclic nucleotide stimulation of PA activity ...
Vibrational analysis of peptides, polypeptides, and proteins. XXIV. Conformation of poly(Α-aminoisobutyric acid)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-10)
Raman and polarized ir spectra have been obtained on built-up monomolecular films of poly(Α-aminoisobutyric acid), and analyzed in the context of normal mode calculations on 3 10 -, Α-, and Α′-helix conformations of this ...
Vibrational analysis of peptides, polypeptides, and proteins. XXI. Β-Calcium-poly( L -glutamate)
(Wiley Subscription Services, Inc., A Wiley Company, 1984-08)
The observed Raman and ir spectra of Ca-poly( L -glutamate) in the Β conformation have been analyzed by means of a normal mode calculation. The force field for the main chain was transferred without refinement from Β-poly( ...
DNA polymerase in nuclei isolated from herpes simplex virus type-2-infected cells. Characterization of the reaction product and inhibition by substrate analogs
(Elsevier, 1984-02-24)
Nuclei isolated from herpes simplex virus (HSV) type 2-infected KB cells were examined for their capacity to serve as an in situ source of herpes DNA polymerase. In contrast to purified enzymes with added template, approx. ...
Development of the catecholamine innervation of the supraoptic nucleus in the Brattleboro rat
(Elsevier, 1984)
The ontogenetic development of the noradrenergic innervation of the supraoptic nucleus was studied in the Brattleboro rat at late postcoital and early postnatal ages. This genetic mutant offers a useful model for analysis ...
The suppression of deprivation and antagonist-induced withdrawal in morphine-dependent rhesus monkeys
(Elsevier, 1984-12)
The capacity of morphine to suppress natural and precipitated withdrawal was compared in morphine-dependent rhesus monkeys. A similar severity of withdrawal was induced by 14-hr deprivation or precipitated by naloxone, ...
Effect of intravenous eicosapentaenoic acid on cerebral blood flow, edema and brain prostaglandins in ischemic gerbils
(Elsevier, 1984-10)
Eicosapentaenoic acid is converted by cyclo-oxygenase to the prostacyclin, PGI3. Consequently eicosapentaenoic acid might protect the brain from the impairment in cerebral blood flow that follows temporary cerebral artirial ...
