A general relation between membrane potential, ion activities, and pump fluxes for symmetric cells in a steady state
(Elsevier, 1974-06)
For steady states of cells that have uniform cell membranes, there must be zero net fluxes of each ion. This provides a set of conditions more restrictive than the condition of zero net current flow that is used to derive ...
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 ...
A general relation between membrane potential, ion activities, and pump fluxes for nonsymmetric cells in a steady state
(Elsevier, 1981-02)
In a previous paper Jacquez and Schultz [Math. Biosci. 20:19 (1974)] derived a set of relations between the membrane potential, ion activities, ion permeabilities, and mediated ion fluxes which held for steady states of ...
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 ...
Regulation of Myo-Inositol Homeostasis in Differentiated Human NT2-N Neurons
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-05)
We have investigated the possible role of second messengers on inositol homeostasis in NT2-N cells, human central nervous system neurons obtained by terminal differentiation of teratocarcinoma precursors. Uptake of inositol ...
Validation of a two-parameter quantitative structure–activity relationship as a legitimate tool for rational re-design of horseradish peroxidase
(Wiley Subscription Services, Inc., A Wiley Company, 2007-09-01)
Previously reported rates of reaction between six mutant strains of the enzyme horseradish peroxidase (HRP) and a test substrate, 2-methoyxpyhenol, were found to correlate with characteristic binding distances computed ...
Paradoxical effect of corticosteroids on pituitary ACTH/[beta]-endorphin release in stressed animals
(Elsevier, 1988)
We have previously demonstrated a number of changes in the anterior lobe proopiomelanocortin (POMC) system in chronically stressed rats. The purpose of the present experiments was to investigate whether chronically stressed ...
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 ...
Mold‐casted non‐degradable, islet macro‐encapsulating hydrogel devices for restoration of normoglycemia in diabetic mice
(Wiley Periodicals, Inc., 2016-11)
Islet transplantation is a potential cure for diabetic patients, however this procedure is not widely adopted due to the high rate of graft failure. Islet encapsulation within hydrogels is employed to provide a three‐dimensional ...
