Multiple frequency EPR studies on three forms of oxidized cytochrome c oxidase
(Elsevier, 1983-10-17)
Bovine heart mitochondrial cytochrome c oxidase (cytochrome aa3) (EC 1.9.3.1) has been demonstrated to occur in several forms when the redox centers in the protein are thought to be fully oxidized. We report here the results ...
Immunochemical studies on the binding specificity of the blood group Leb specific lectin Griffonia simplicifolia IV
(Elsevier, 1983-05)
The specificity of the Griffonia simplicifolia IV (GS-IV) lectin was studied by quantitative precipitin and quantitative precipitin inhibition assays. The lectin precipitated most strongly with a human H,Leb blood group ...
Anodic oxidation of dihydronicotinamide adenine dinucleotide at solid electrodes; mediation by surface species
(Elsevier, 1983-02-10)
The mechanism and kinetics for the two-electron oxidation of 1.4-dihydronicoeueamide adenine dinucleotide (NADH) to NAD+ at gold, platinum and glassy carbon (GC) rotating case electrodes at various solution pH and NADH ...
Development of hypothalamic opioid neurons: A combined immunocytochemical and [3H]thymidine autoradiographic study
(Elsevier, 1985-02)
Using a combined technique of immunocytochemistry and [3H]thymidine autoradiography, we have determined the "birth-date" of opioid peptide containing neurons in three hypothalamic nuclei. These include proopiomelanocortin ...
A specific radioimmunoassay for androstenedione with reduced bridge-binding
(Elsevier, 1984-09)
Antibody used in a steroid radioimmunoassay raised against a steroid hapten-carrier protein conjugate may recognize both the hapten and the chemical bridge to the protein. Use of the same bridge in the radioisotopic label ...
Thermophysics of metal alkanoates IV. Heat capacities and thermodynamic properties of potassium 2-methylpropanoate
(Elsevier, 1984-02)
The molar heat capacity of potassium 2-methylpropanoate, (CH3)2CHCO2K, has been measured between 8 and 350 K by adiabatic calorimetry, and found to be normal. The corresponding thermodynamic functions have been calculated. ...
On the dynamic structure factor, S(q,[omega]), of polymers in dilute solution
(Elsevier, 1981-08)
In principle, interpretation of dynamic scattering experiments requires theoretical calculation of either intermediate scattering functions S(q,t) or dynamic structure factors S(q,[omega]). Although dynamic scattering ...
Effect of gravity on Brownian flocculation
(Elsevier, 1984-09)
In previous analyses of simultaneous Brownian and gravity-induced flocculation, it has been assumed that each mechanism contributes independently to the total flocculation rate. In this paper the rigorous problem of coupled ...
Stereochemistry in the cyclization of -azidophenylalkenes to indoles
(Elsevier, 1983)
- and --azidostilbene, -azido-[beta]-methylstilbene, and ()--azido[beta]-deuteriostyrene give indoles on thermolysis by a mechanism involving attack by a nitrene directly on the [beta] carbon atom, and not by insertion.
Transition dipole interaction in polypeptides: Ab initio calculation of transition dipole parameters
(Elsevier, 1984-06-15)
Ab initio calculations of dipole moment derivatives of a model system of N-methylacetamide hydrogen-bonded to two formamide molecules give values for amide I and amide II transition dipole moments consistent with those ...
