Biological effects of a novel intestinal peptide -- inhibiting enterocytogenin on cultured 3T3 mouse fibroblasts and L5178Y mouse lymphoma cells
(Elsevier, 1994-05-05)
The effects of a new intestinal peptide, inhibiting enterocytogenin (IEG) derived from pig intestinal mucosa were studied in vitro on 3T3 mouse fibroblasts and L5178Y mouse lymphoma cell line. IEG caused considerable growth ...
An intramolecular, Schmidt reaction of an alkyl azide with a carbocation. The generation and rearrangement of a conformationally restricted secondary aminodiazonium ion.
(Elsevier, 1992-09-08)
Treatment of azidoalkene 2 with triflic acid produced the bridged bicyclic enamine 3 by an intramolecular Schmidt reaction. Rearrangement of the intermediate aminodiazonium ion 5 is completely regioselective.
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 ...
Transferrin: A potential source of iron for oxygen free radical-mediated endothelial cell injury
(Elsevier, 1992-04)
The ability of transferrin to potentiate oxygen free radical-mediated endothelial cell injury was assessed. 51Cr-labeled endothelial cells derived from rat pulmonary arteries (RPAECs) were incubated with hydrogen peroxide ...
Expression of prodynorphin-derived peptides and mRNA in guinea-pig cortex
(Elsevier, 1993-08)
The distributions and extent of processing of four prodynorphin-derived peptides (dynorphin A (1-17), dynorphin A (1-8), dynorphin B, and [alpha]-neoendorphin) were determined in ten regions of the cortex as well as in the ...
