A rapid attenuation of muscarinic agonist stimulated phosphoinositide hydrolysis precedes receptor sequestration in human SH-SY-5Y neuroblastoma cells
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-05)
Agonist occupancy of muscarinic cholinergic receptors in human SH-SY-5Y neuroblastoma cells elicited two kinetically distinct phases of phosphoinositide hydrolysis when monitored by either an increased mass of inositol ...
Irreversible enzyme-shuttle immunoassay
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
The concept of a competitive enzyme immunoassay that utilizes simultaneously the bound and the free analyte-enzyme conjugate (heterobifunctional conjugate) for signal generation in response to varying analyte concentrations ...
Repeated haloperidol increases both calmodulin and a calmodulin-binding protein in rat striatum
(Elsevier, 1994-12)
Repeated treatment with the antipsychotic drug, haloperidol, leads to an increased behavioral sensitivity to dopamine agonists exhibited upon withdrawal from the drug. An increase in the particulate content of the endogenous ...
Degradation kinetics of pentachlorophenol by Phanerochaete chrysosporium
(Wiley Subscription Services, Inc., A Wiley Company, 1990-05)
The extracellular enzymes and cell mass from the pregrown Phanerochaete chrysosporium cultures were used for the degradation of PCP. The use of both extracellular enzymes and cell mass resulted in extensive mineralization ...
1-Monoglyceride production from lipase-catalyzed esterification of glycerol and fatty acid in reverse micelles
(Wiley Subscription Services, Inc., A Wiley Company, 1991-08-20)
Glycerol-fatty acid esterification has been conducted with lipase from R. delemar in water/AOT/isooctane reverse micellar media, with the major product being 1-monoglyceride, a useful food-emulsifier. 1,3-diglyceride was ...
Frequent harvesting from perfused bone marrow cultures results in increased overall cell and progenitor expansion
(Wiley Subscription Services, Inc., A Wiley Company, 1994-08-20)
The establishment of prolific long-term human bone marrow cultures has led to the development of hematopoietic bioreactor systems. A single batch expansion of bone marrow mononuclear cell populations leads to a 10- to ...
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 ...
Microencapsulated human bone marrow cultures: A potential culture system for the clonal outgrowth of hematopoietic progenitor cells
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-05)
Currently the most successful methods for culturing human hematopoietic cells employ some form of perfused bioreactor system. However, these systems do not permit the clonal outgrowth of single progenitor cells. Therefore, ...
Optimizing seeding and culture methods to engineer smooth muscle tissue on biodegradable polymer matrices
(Wiley Subscription Services, Inc., A Wiley Company, 1998-01-05)
The engineering of functional smooth muscle (SM) tissue is critical if one hopes to successfully replace the large number of tissues containing an SM component with engineered equivalents. This study reports on the effects ...
Substitution of D-Trp 32 in NPY Destabilizes the Binding Transition State to the Y1 Receptor Site in SK-N-MC Cell Membranes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-04)
The retention rate of the spin label 3-isothiocyanto methyl-2,2,5,5-tetramethyl-1-pyrrolidinyl oxyl spin label (proxyl) attached to the porcine N-acetyl-NPY peptide and the porcine N-acetyl-D-Trp 32 -NPY peptide at Lys 4 ...
