Clocinnamox blocks only mu receptors irreversibly: Binding evidence
(Elsevier, 1994-11-10)
Thermodynamic properties of silicides. II. Heat capacity at temperatures T from 5.9 K to 341 K and derived thermodynamic properties to T = 1200 K of tungsten disilicide: WSi2.06
(Elsevier, 1993-11)
The heat capacity of tungsten disilicide WSi2.06 was measured over the temperature range 5.9T/K)-2[middle dot]mol-1. For the lattice, the Debye characteristic temperature [Theta]CD = (317.8+/-3.3) K. From our results, the ...
Shape-selective separation of polycyclic aromatic hydrocarbons by reversed-phase liquid chromatography on tetraphenylporphyrin-based stationary phases
(Elsevier, 1993-07-02)
The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary ...
Purification of Dihydroxyacetone Phosphate Acyltransferase from Guinea Pig Liver Peroxisomes
(Elsevier, 1993-01)
Dihydroxyacetone phosphate acyltransferase (EC 2.3.1.42), a peroxisomal enzyme which initiates the biosynthesis of glycerolipids (especially the ether-linked glycerolipids) in higher eukaryotes, has been purified by over ...
Heating characteristics and atomic emission waveforms for glow discharge ion bombardment furnaces
(Elsevier, 1991)
Ion bombardment of a graphite cathode in a glow discharge plasma is used to heat the cathode to temperatures suitable for the vaporization of solution residues from the cathode surface. Two low-mass cathode configurations ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
A comparison of proteins and peptides as substrates for microsomal and solubilized oligosaccharyltransferase
(Elsevier, 1994-11)
A chemoenzymatic synthesis of homogeneous neoglycoproteins and glycopeptides was explored using oligosaccharyltransferase isolated from yeast. Neither the microsomal form nor the solubilized form of the enzyme catalyzed ...
Benzimidazole ribonucleosides: Observation of an unexpected nitration when performing non-aqueous diazotizations with t-butyl nitrite
(Elsevier, 1992-09)
Mild, non-acidic conditions used in the non-aqueous diazotization of a 2-aminobenzimidazole nucleoside with t-butyl nitrite gave an unexpected 4-nitrobenzimidazol-2-one nucleoside which was not formed when primary alkyl ...
Triple Junction Mobility: A Molecular Dynamics Study
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle ...
Thermodynamics of alkali alkanoates IX. Heat capacity and thermodynamic functions of lithium 2-methylpropanoate at temperatures from 7 K to 535 K
(Elsevier, 1993-10)
The heat capacity of lithium 2-methylpropanoate was measured by equilibrium adiabatic calorimetry at temperatures, T from 7 K up to 350 K and by d.s.c. from 330 K through melting to 535 K. A small diffuse hump was observed ...
