Generation of drug metabolite antigenicity in the intestinal mucosa
(Elsevier, 1986-08)
Both nitroreductase and transglutaminase activities have been assayed in the 10 000 x g supernatant fluids of rat intestine homogenates after Triton X-100 treatment. Incubation of 14C-nitrofurantoin in the intestine ...
The thermodynamics of the divalent metal fluorides. III. Heat capacity of the fast ion conductor SrSnF4 from 6 to 344 K
(Elsevier, 1989-07)
The heat capacity of the fast ion conductor SrSnF4 was measured by adiabatic calorimetry from 6 T/K 19F spin-lattice relaxation time T1 occurs. Standard molar thermodynamic functions are given at selected temperatures from ...
13C/12C exchange between calcite and graphite: A possible thermometer in Grenville marbles
(Elsevier, 1981-03)
The fractionation of 13C between calcite and graphite, [Delta](Cc-Gr). is consistently small (2.6-4.8 permil) in 34 assemblages from upper amphibolite- and granulite-facies marbles of the Grenville Province. In 25 samples ...
Vibrational spectra, assignments and normal coordinate analyses for crystalline zirconium tetrachloride and tetrabromide
(Elsevier, 1981)
Raman and far-IR spectra have been obtained of crystalline ZrCl4 and ZrBr4. The observed frequencies have been interpreted on the basis of the C2h symmetry of the Bravais unit cell and have been subjected to a normal ...
Increased sensitivity of adenylate cyclase activity in the striatum of the rat to calmodulin and GppNHp after chronic treatment with haloperidol
(Elsevier, 1986-06)
Chronic treatment of rats with haloperidol causes behavioral supersensitivity to dopaminergic agonists and an increase in the sensitivity of adenylate cyclase activity in the striatum to stimulation by dopamine. In this ...
Is cytochrome aa3 from thermus thermophilus a single subunit oxidase?
(Elsevier, 1983)
A reliable procedure has been developed for the purification of the cytochrome c1aa3 complex from the plasma membrane of T. thermophilus. The ratios heme C:heme A:Fe:C were found to be 1:2:3:2 confirming previous results, ...
The determinants of divalent/monovalent selectivity in anion exchangers
(Elsevier, 1983-04)
This research demonstrates that it is the distance of fixed-charge separation in the resin which is the primary determinant of divalent/monovalent selectivity. Anion resins, particularly acrylics and epoxies, with closely ...
Akermanite in the Cascade Slide xenolith and its significance for regional metamorphism in the Adirondacks
(Springer-Verlag, 1980-06)
Akermanite (Ak 90 ) coexists with monticellite (Mo 92 ) and wollastonite (Wo 99 ) in an unusual calc-silicate xenolith in anorthosite at Cascade Slide in the Adirondack Mountains, New York. Experimental results bearing on ...
CPS K 843 Radiation-induced crosslinking: Effect on structure of polyethylene
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1985-02)
Branched polyethylene irradiated (0–400 Mrad) with a Co 60 source at room temperature under vacuum was studied by density, wide- and small-angle X-ray scattering (WAXS and SAXS) measurements. The radiation effects on the ...
