Decreased formation of inositol trisphosphate in Madin-Darby canine kidney cells under conditions of [beta]-glucosidase inhibition
(Elsevier, 1992-02-01)
Recent work has demonstrated the enhancement of hormone-stimulated inositol trisphosphate formation in renal epithelial cells under conditions of glucosylceramide depletion. The role of glucosylceramide metabolism was ...
Thermodynamics of ammonium halopallidates I. Heat capacity and thermodynamic properties of (NH4)2PdCl6 at temperatures from 6 K to 350 K
(Elsevier, 1992-09)
The heat capacity of ammonium hexachloropallidate (NH4)2PdCl6 was measured at temperatures from 6 K to 350 K by adiabatic calorimetry. The heat-capacity curve is smooth and without anomalies. It rises rapidly from T0 to T ...
Imaging of metabolism and autonomic innervation of the heart by positron emission tomography
(Springer-Verlag, 1992-06)
Positron emission tomography (PET) allows, in combination with multiple radiopharmaceuticals, unique physiological and biochemical tissue characterization. Tracers of blood flow, metabolism and neuronal function have been ...
Effects of ammonia and lactate on hybridoma growth, metabolism, and antibody production
(Wiley Subscription Services, Inc., A Wiley Company, 1992-02-20)
The influence of ammonia and lactate on cell growth, metabolic, and antibody production rates was investigated for murine hybridoma cell line 163.4G5.3 during batch culture. The specific growth rate was reduced by one-half ...
Neural retina-specific leucine zipper gene NRL (D14S46E) maps to human chromosome 14q11.1-q11.2
(Elsevier, 1992-10)
The product of a neural retina-specific gene, NRL, belongs to the "leucine zipper" family of DNA-binding proteins and has a strong similarity to the v-maf oncogene product. The NRL gene maps to human chromosome 14 by ...
Vibrational spectroscopic studies of -alternating valine peptides
(Elsevier, 1992-04-24)
Raman and infrared spectra of Boc-(Val--Val)n-OMe [(-Val)n], with n = 4, 6 and 8, were obtained in crystalline and solution states. Based on predictions from normal-mode calculations of a number of relevant single- and ...
Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
Synthesis and characterization of 7-nitrobenzo-2-oxa-1,3-diazole (NBD)-labeled fluorescent opioids
(Elsevier, 1992-01-22)
Alkylation of sarcosine with 4-chloro-nitrobenzo-2-oxa-1,3-diazole (NBD-chloride) furnished a fluorescent tag that was coupled with a tetrahydrothebaine derivative and [beta]-naltrexamine, respectively, to yield the ...
Normal-mode analysis of infrared and Raman spectra of poly(vinyl fluoride)
(Elsevier, 1992-03-02)
Infrared and Raman spectra of samples of poly(vinyl fluoride) (PVF) have been recorded. The vibrational spectra have been analyzed by means of normal-mode calculations. A force field was derived by using 2-fluorobutane as ...
