Nitric Oxide Synthase Activity in Genetic Hypertension
(Elsevier, 1993-07-30)
A porphyrinic sensor was used to monitor nitric oxide released from cultured endothelial and vascular smooth muscle cells obtained from genetically hypertensive rats and from a normotensive reference strain of rats. ...
A generalization of the Goldman equation, including the effect of electrogenic pumps
(Elsevier, 1971-10)
An equation similar to the Goldman equation is derived for the steady-state diffusion of univalent ions across a membrane with arbitrary potential profile and in the presence of electrogenic pumps. The presence of electrogenic ...
Localization of sequences related to the human RAD6 DNA repair gene on mouse Chromosomes 11 and 13
(Springer-Verlag, 1995-04)
Cell proliferation-associated expression of a recently evolved isozyme of triosephosphate isomerase
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-04)
An electrophoretically unique, thermolabile isozyme of triosephosphate isomerase (TPI; EC 5.3.1.1) accounts for 10–30% of the enzymatic activity in a range of mitotically active human cells and tissues. This type 2 form ...
Principle of superposition-free memory
(Elsevier, 1977-07-21)
The requirement that memory be superposition-free imposes a restrictive condition on the structure of neural models. A simple model which satisfies this condition consists of two levels of neurons, with primary level neurons ...
Isolation of plasma membranes from bovine corpus luteum possessing adenylate cyclase, 125I-hCG binding and Na---K-ATPase activities
(Elsevier, 1974-01-23)
Plasma membranes from bovine corpora lutea have been purified by sucrose density gradient centrifugation. The purified membranes, in addition to binding 125I-hCG, also possess hCG-stimulated adenylate cyclase and Na---K-ATPase. ...
Localization of thyrotropin-releasing hormone receptor and thyrotroph embryonic factor on mouse Chromosome 15
(Springer-Verlag; Springer-Verlag New York, Inc., 1993-10)
The effect of mean and variance in resource supply on survival of annuals from Mediterranean and desert environments
(Springer-Verlag, 2004-10)
Resource availability is often characterized by mean annual amounts, while ignoring the spatial variation within habitats and the temporal variation within a year. Yet, temporal and spatial variation may be especially ...
Receptor-related interactions of opiates with PGE-induced adneylate cyclase in brain
(Elsevier, 2006-04-07)
The inhibition by opiates of the PGE2-induced formation of cAMP in slices from rat brain striatum was investigated. A maximal, 3.5-fold increase over the basal level of cAMP was obtained with an EC50 for PGE2 of 3 [mu]M. ...
The mechanism of amine inhibition of the photosynthetic oxygen evolving complex : Amines displace functional chloride from a ligand site on manganese
(Elsevier, 1983-10-17)
Amines inhibit photosynthetic oxygen evolution by binding to manganese in the oxygen evolving complex. This inhibition is more effective if chloride is absent. Steady-state kinetic analyses show that ammonia and chloride ...
