High-resolution analysis of c-fos chromatin accessibility using a novel DNase I-PCR assay
(Elsevier, 1992-04-06)
In our previous study, c-fos chromatin accessibility was assayed using DNase I digestion and Southern blot analysis. This low-resolution mapping of c-fos chromatin accessibility demonstrated that serum stimulation of the ...
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 ...
Studies on morpholinosphingolipids: Potent inhibitors of glucosylceramide synthase
(Elsevier, 1994-04-25)
Synthetic 1-morpholino-1-deoxyceramides were designed to inhibit glucosylceramide synthase. The most potent inhibitor 2a possesses the unnatural R,R-configuration of D-threo-sphingosine.
Immobilization of proteins on gold coated porous membranes via an activated self-assembled monolayer of thioctic acid
(Springer-Verlag, 1995-09)
A new methodology for efficient protein (e.g., antibodies, enzymes, etc.) immobilization on microporous nylon membranes for use in a variety of bioanalytical systems is introduced. The method utilizes an activated ...
A 1.8 Å resolution potential function for protein folding
(Wiley Subscription Services, Inc., A Wiley Company, 1990-08-15)
A general method is presented for constructing a potential function for approximate conformational calculations on globular proteins. The method involves solving a nonlinear program that seeks to adjust the potential's ...
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 ...
Low-temperature MOCVD of chromium carbonitride coatings from tetrakis(diethylamido)chromium and pyrolysis mechanism of this single-source precursor
(John Wiley & Sons, Ltd., 1998-03)
Amorphous chromium carbonitride coatings with a low nitrogen content (3–8 at%) were deposited by low-pressure MOCVD in the temperature range 573–793 K using Cr(NEt 2 ) 4 as single-source precursor. This poor nitrogen ...
Report On ‘The MATCH Program: Integrating Student Learning in Science and Math’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
The inability to integrate mathematics and chemistry continues to plague science and math undergraduates. General chemistry students often lack the ability to apply the mathematics they already know to problems given in ...
Off-diagonal disorder model for exciton polaritons in layered media. Disorder-induced origin of radiative widths
(Elsevier, 1994-10-07)
Excitons in an infinite layered dipolar medium, such as a layered crystal or a multiple-quantum-well stack, with perfect periodicity exhibit a vanishing radiative width due to the requirement of energy-momentum conservation. ...
