Iron and manganese superoxide dismutases
(Elsevier, 1983)
Fe and Mn SDs are enigmatic metalloproteins for several reasons: They are found in strict anaerobes as well as aerobes. In some cases the Fe and Mn ions appear to be interchangeable while in others they are not. In some ...
Thermophysics of metal alkanoates II. Heat capacities and thermodynamic properties of sodium propanoate
(Elsevier, 1983-07)
The heat capacity of sodium propanoate has been measured from 9 to 580 K by adiabatic calorimetry and considerable metastability noted between 60 and 215 K. Values at 298.15 K of Cp,m/R, Smo/R, "Hmo-Hmo(0)'/R, and ...
Separation of hemoglobin types by cation-exchange high-performance liquid chromatography,
(Elsevier, 1983-10-01)
The use of a recently developed cation-exchange HPLC packing material for the separation of hemoglobin types in human blood has been investigated. Adult and newborn hemolysates from normal individuals and from subjects ...
Reconstitution of a cyclic amp-dependet protein kinase from Dictyostellium discoideum
(Elsevier, 1983-07-28)
Dicytostelium discoideum has a cyclic AMP-dependent protein kinase activity which can be assayed after DEAE-ion exchange chromatography. Mixing cAMP binding protein (free of kinase activity) from the DEAE column eluate ...
Platelet alpha2 adrenoreceptors are decreased in number after antidepressant therapy
(Elsevier, 1983)
1. 1. Specific binding of 3H-clonidine to alpha2 adrenoreceptors upon human blood platelet membranes is increased in patients with major depressive disorder (endogenous depression).2. 2. Specific binding of 3H-yohimbine ...
The distribution of cholecystokinin and vasoactive intestinal peptide in rhesus monkey brain as determined by radioimmunoassay
(Elsevier, 1983-07)
The concentration of cholecystokinin (CCK) and vasoactive intestinal peptide (VIP) in dissected cortical and subcortical areas of four rhesus monkeys' brains was determined by radioimmunoassay (RIA). Cerebral cortical ...
A novel approach towards the synthesis of the 3,4,5-trihydro-1,3-diazepin-5-ol ring structure
(Elsevier, 1983)
A catalytic reduction of the nitrile portion of the trimethylsilyl cyanohydrin to a primary amine has produced an situ annulation to generate the 3,4,5-trihydro-1,3-diazepin-5-ol ring. This ring substructure has demonstrated ...
A new procedure for the synthesis of polyethylene glycol-protein adducts; Effects on function, receptor recognition, and clearance of superoxide dismutase, lactoferrin, and [alpha]2-macroglobulin
(Elsevier, 1983-05)
A new, simplified technique for the synthesis of polyethylene glycol (PEG) derivatives of proteins utilizing 1,1'-carbonyldiimidazole for PEG activation, is described. PEG derivatives of superoxide dismutase, [alpha]2-ma ...
