Adenosine depresses spontaneous transmitter release from frog motor nerve terminals by acting at an A1-like receptor
(Elsevier, 1990)
Adenosine (1[mu]M to 1mM) depressed spontaneous transmitter release from frog motor nerve terminals without producing any observable postsynaptic effects. Since this action of adenosine was blocked by 20[mu]M theophylline ...
Heterogeneity and organization of the ribosomal RNA genes of Cucurbita maxima
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-06)
Thirty-six clones were recovered from Cucurbita maxima genomic DNA which had been enriched for rDNA and cleaved at the unique repeat unit Hin d III site. Twenty-nine of these, which contain complete rDNA units, were compared ...
Amino acid sequence of pheromone-inducible surface protein in Enterococcus faecalis, that is encoded on the conjugative plasmid pPD1
(Elsevier, 1990-07-30)
The major pheromone-inducible protein, PD78, believed to contribute to bacterial conjugation, was purified from Enterococcus (formerly Streptococcus) faecalis cells containing the plasmid pPD1. A cloned EcoRI-Bg1II 3.6-kbp ...
Maximization of Daily Canopy Photosynthesis: Effects of Herbivory on Optimal Nitrogen Distribution
(Elsevier, 1994-08-07)
Recent models have shown that higher leaf nitrogen concentration per unit area maximizes nitrogen use efficiency with increasing light intensity. As a result, total canopy photosynthesis is maximized when nitrogen ...
Reduction of porous media permeability from in situ Leuconostoc mesenteroides growth and dextran production
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-05)
In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, ...
Proposed nomenclature for human butyrylcholinesterase genetic variants identified by DNA sequencing
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-02)
1. New information identifying nucleotide alterations of human butyrylcholinesterase allows the use of more specific nomenclature for the variants commonly known as atypical, fluoride, silent, and K variant.
The Stimulation of pp42mapkinase by Insulin Does Not Correlate with Its Metabolic Actions in Cells Overexpressing Mutant Insulin Receptors
(Elsevier, 1993-10-15)
Naturally occurring human insulin receptor mutants Ser1200 and Thr1134, and a site-directed mutant Arg1030 overexpressed in Chinese hamster ovary (CHO) cells, bind insulin with affinities identical to wildtype receptors ...
Cell cycle dependence of retroviral transduction: An issue of overlapping time scales
(Wiley Subscription Services, Inc., A Wiley Company, 1998-04-20)
Recombinant retroviruses are currently used as gene delivery vehicles for the purpose of gene therapy. It is generally believed that the efficiency of retroviral transduction depends on the cell cycle status of the target ...
Coming to terms with heritability
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-06)
The complex mechanisms of heredity are little appreciated by non-specialists, in some measure, because of misunderstandings that are perpetuated when words used for technical terms have other, more widely understood, folk ...
