Prostaglandin biosynthesis does not participate in isoproterenol-induced renin release
(Elsevier, 1984-05-07)
Rat renal slices were incubated in two different media. One was a normal K. physiological saline solution and the other a high K medium. Renin release was measured every 15 min in the presence and absence of 10-6M isoproterenol ...
The transformation of Saperda calcarata (Coleoptera: Cerambycidae) into a cellulose digester through the inclusion of fungal enzymes in its diet
(Springer-Verlag, 1986-12)
The larvae of the aspen borer, Saperda calcarata , which feed on the inner bark and sapwood of living aspen stems, are unable to digest cellulose. However, they can be transformed into cellulose digesters by adding the ...
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 ...
Beyond nutrients: Food‐derived microRNAs provide cross‐kingdom regulation
(WILEY‐VCH Verlag, 2012-04)
Food turns out to be not only the nutrient supplier for our body but also a carrier of regulatory information. Interestingly, a recent study made the discovery that some plant/food‐derived microRNAs (miRNAs) accumulate in ...
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 ...
A reverse double-isotope enzymatic histamine assay: Advantages over single-isotope methods
(Elsevier, 1977-11-15)
High concentrations of codeine necessary to demonstrate histamine release from leukocytes interfere with histamine methylation, producing a concentration-dependent flattening of the histamine standard curves obtained from ...
Viroplasm and large virus-like particles in the dinoflagellate Gymnodinium uberrimum
(Springer-Verlag, 1979-09)
Virus-like particles (VLPs) measuring 385±5 nm in diameter are described in the freshwater dinoflagellate Gymnodinium uberrimum . The VLPs are found in association with, and “budding” from a vesicular viroplasmic area. A ...
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 ...
Terminal sequences of lysosome solubilized pig liver cytochrome b5 reductase
(Elsevier, 1980-08-29)
SummaryLysosome solubilized pig liver cytochrome b5 reductase has the following twenty residues as NH2-terminal sequence: Ser-Thr-Pro-Ala-Ile-Thr-Leu-Glu-Asn-Pro-Asp-Ile-Lys-Tyr-Pro-Leu-Arg-Leu-Ile-Asp. The fragment is ...
