S1.23 Investigation of the sialyltransferases present in two populations of ehrlich ascites tumor cells
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1993-08)
Inactivation of Escherichia coli 2-amino-3-ketobutyrate CoA ligase by phenylglyoxal and identification of an active-site arginine peptide
(Elsevier, 1992-11-15)
Treatment of homogeneous preparations of 2-amino-3-ketobutyrate CoA ligase from Escherichia coli, a pyridoxal 5'-phosphate-dependent enzyme, with phenylglyoxal, 4-(oxyacetyl)phenoxyacetic acid, 2,3-butanedione, or ...
Selective effect of alcohol on cellular immune responses of lymphocytes from AIDS patients
(Elsevier, 1994)
In this study we examined the in vitro effects of alcohol on the proliferative responses of lymphocytes from healthy donors and AIDS patients to a recombinant fusion peptide, env-gag, corresponding to portions of the gp ...
Direct optical resolution of vesamicol and a series of benzovesamicol analogues by high-performance liquid chromatography
(Elsevier, 1994-04-29)
The direct optical resolution of the vesicular acetylcholine uptake inhibitors vesamicol and benzovesamicol and nine benzovesamicol analogues were performed by HPLC on a commercially available cellulose tris(3,5-dimethylphenyl ...
Modulation of opioid signal transduction in SH-SY5Y neural cells by differentiating agents: Concurrent mu receptor upregulation and effector desensitization by phorbol ester
(Elsevier, 1994-02-21)
Long-term exposure of SH-SY5Y human neural cells to retinoic acid (RA) increased the binding of [3H]DAMGO and [3H]DPDPE by up to 3-fold compared to membranes of untreated cells. In contrast, incubation of the cells with ...
Expression of Wild-Type and Mutant Rat Liver CTP: Phosphocholine Cytidylyltransferase in a Cytidylyltransferase-Deficient Chinese Hamster Ovary Cell Line
(Elsevier, 1994-05)
The strain 58 Chinese hamster ovary (CHO) mutant defective in CTP:phosphocholine cytidylyltransferase was characterized as an expression system for exogenous cytidylyltransferase. Strain 58 cells express less than 5% of ...
Slouching toward a systems approach to treatment
(Elsevier, 1994)
Both the health care sector generally and the alcohol and drug field are moving toward a truly systematic approach to treatment, accelerated by the anticipated advent of health care reform. There is considerable reluctance ...
Interaction of viable group a streptococci and hydrogen peroxide in killing of vascular endothelial cells
(Elsevier, 1993-05)
Previous studies have shown that the streptococcal hemolysin, streptolysin S, is capable of interacting with hydrogen peroxide (H2O2) to injure vascular endothelial cells (Free Radic. Biol. Med. 7:369-376; 1989). To extend ...
