Continuous monitoring of gas-phase species at trace levels with electrochemical detectors : Part 2. Detection of chlorine and hydrogen chloride
(Elsevier, 1991-08-01)
A detection system for the continuous and simultaneous measurement of gas-phase chlorine and hydrogen chloride in the low parts per billion (109) by volume (ppbv) range is described. Both gases are trapped through the walls ...
Interactions of intracellular mediators of amylase secretion in permeabilized pancreatic acini
(Elsevier, 1991-01-23)
Mouse pancreatic acini were permeabilized with streptolysin O to investigate amylase secretion stimulated by various intracellular mediators and the kinetics of secretion as a function of temperature. Amylase secretion was ...
Rapid kidney changes resulting from glycosphingolipid depletion by treatment with a glucosyltransferase inhibitor
(Elsevier, 1991-04-24)
The ceramide analog, -threo-1-phenyl-2-decanoylamino-3-morpholino-1-morpholino-1-propanol, inhibits the glucosylation of ceramide and thus, by virtue of the normal catabolism of the higher glucosphingolipids, leads to a ...
Non-biomimetic route to deoxyadenosine adducts of carcinogenic polycyclic aromatic hydrocarbons
(Elsevier, 1991-10-21)
Aminotriols are prepared by direct aminolysis of the diol epoxides of polycyclic aromatic hydrocarbons, providing a substantial improvement over literature methods. The condensation of aminotriols with 6-halopurine ...
Excitatory amino acidergic pathways and receptors in the basal ganglia
(Springer-Verlag, 1991-10)
The striatum receives the majority of excitatory amino acidergic input to the basal ganglia from neocortical and allocortical sources. The subthalamic nucleus and the substantia nigra also receive excitatory amino acidergic ...
Highly stereoselective preparation of nitro olefins and nitro dienes by the addition-elimination of copper-zinc organometallics to [beta]-alkylthio and [beta]-phenylsulfonyl nitro olefins
(Elsevier, 1991-01-21)
The addition-elimination of copper-zinc organometallics RCu(CN)ZnX to (E)-1-nitro-2-phenylsulfonyl ethylene 2a gave highly functionalized pure (E) nitro olefins and stereoselectively (1E, 3E) and (1E, 3Z)-1-nitrodienes in ...
Construction of molecular mechanics energy functions by mathematical transformation of ab initio force fields and structures
(John Wiley & Sons, Inc., 1991-04)
A method is presented by which ab initio (or empirical) force fields and structures can be converted to molecular mechanics energy parameters. Using Cartesian coordinates, the effect of van der Waals and other nonquadratic ...
Reactions of polycyclic alkylaromatics: Structure and reactivity
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1991-11)
A family of alkyl-substituted polycyclic aromatic hydrocarbons was pyrolyzed in microbatch reactors at temperatures between 350°C and 425°C. A general pyrolysis network was deduced for these compounds, and it comprised two ...
Fat-preferring rats consume more alcohol than carbohydrate-preferring rats
(Elsevier, 1991)
Rats with a genetic preference for alcohol (ETOH) have been found to consume more dietary fat then ETOH nonpreferring rats. We therefore hypothesized that rats selected on the basis of fat and carbohydrate (CHO) preferences ...
