Steroid Metabolism by Rabbit Olfactory-Specific P450 2G1
(Elsevier, 1994-12)
Cytochrome P450 2G1 (2G1), which is uniquely expressed in the olfactory mucosa in mammals, may have important physiological functions. In the present study, we have examined the catalytic activity of rabbit 2G1 toward a ...
Magnetic resonance studies of intercalated, two-dimensional transition metal chalcogenophosphate lattices
(Elsevier, 1994-02-25)
Transition metal chalcogenophosphates with the formula M2P2X6 (where M is a divalent transition metal and X = S, Se) form a family of compounds with layered structures that offer chemically accessible interlamellar spaces ...
The microwave spectrum of cyclopropane [middle dot] ammonia. A novel structure for cyclopropane complexes
(Elsevier, 1994-02-18)
The microwave spectrum of the cyclopropane[middle dot]ammonia (C3H6[middle dot]14NH3) complex has been observed using a pulsed nozzle, Fourier-transform microwave spectrometer. The spectrum is characteristic of a symmetric ...
Phase transformations of a liquid crystalline epoxy during curing
(Elsevier, 1994-06)
The phase transformations of a novel liquid crystalline epoxy, diglycidyl ether of 4,4'-dihydroxy-[alpha]-methylstilbene (DGEDHMS), from isotropic phase to liquid crystalline phase during curing have been studied using a ...
Output feedback control of nonminimum-phase nonlinear processes
(Elsevier, 1994-07)
This work concerns the development of a general framework for the analysis and output feedback control of open-loop stable nonminimum-phase nonlinear processes. A Smith-type abstract operator structure is introduced, ...
The reaction of sulfur with dilithio compounds. The syntheses and structures of phenanthro [1, 10-cd]-1,2-dithiole and phenanthro[4,5-cde] [1,2]dithiin
(VCH Publishers, Inc.Wiley Periodiocals, Inc., 1994-04)
The sequential reaction of selected polycyclic aromatic hydrocarbons with butyllithium/TMEDA/hexane and sulfur allows preparation of ring-fused dithiins, dithioles, and thiophenes. In this manner, phenanthrene has been ...
Glycine-extended post-translational processing intermediates of gastrin and cholecystokinin in the gut
(Elsevier, 1994-02-03)
Cholecystokinin (CCK) and gastrin are two polypeptide hormones of the gut that share complete structural homology in their carboxyl-terminal pentapeptide. Both peptides are biologically activated from their glycine-extended ...
Vibrational analysis of glutathione
(Wiley Subscription Services, Inc., A Wiley Company, 1994-10)
Infrared and Raman spectra have been obtained of crystalline glutathione and its deuterated derivative and interpreted by normal mode analysis. The force field consisted of our empirical force fields for the peptide group ...
Investigation of nematic liquid crystals as surface acoustic wave sensor coatings for discrimination between isomeric aromatic organic vapors
(Elsevier, 1994-04-11)
The use of thermotropic nematic liquid crystals (LC) as surface acoustic wave (SAW) vapor sensor coatings were investigated. Responses to four pairs of isomeric aromatic organic vapors were measured using two LC coatings ...
