Human neutrophils permeabilized with digitonin respond with lysosomal enzyme release when exposed to micromolar levels of free calcium
(Elsevier, 1986-04-08)
We have recently reported that human neutrophils can be permeabilized with the cholesterol complexing agent saponin and that these cells can be induced to secrete the granule enzyme lysozyme in response to micromolar levels ...
A structural comparison of the A and B subunits of Griffonia simplicifolia I isolectins
(Elsevier, 1984-02-15)
A structural comparison between the A and B subunits of the five tetrameric Griffonia simplicifolia I isolectins (A4, A3B, A2B2, AB3, B4) was undertaken to determine the extent of homology between the subunits. The first ...
Binding of Griffonia simplicifolia I lectin to rat pulmonary alveolar macrophages and its use in purifying type II alveolar epithelial cells
(Elsevier, 1986-01-23)
We report that the isolectin Griffonia simplicifolia I-B4 isolated from G. simplicifolia seeds binds to rat alveolar macrophages present in frozen sections of lung tissue or bronchoalveolar lavage fluid. G. simplicifolia ...
Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
The illumination of molecular behavior by electron waves
(Elsevier, 1985-01)
Aspects of vapor-phase electron diffraction are discussed, singling out the seminal contributions of Yonezo Morino in collaboration with San-ichiro Mizushima and others. Recent developments leading to a precision approaching ...
Properties of diacylglycerol kinase in adult and fetal rat lung
(Elsevier, 1982-12-13)
Diacylglycerol kinase activity is found in both adult and fetal lung. Approximately 27 and 52% of the total activity is found in microsomes and cytosol, respectively. The activity is maximal at pH 7.4. The apparent Km for ...
Intrathecal bombesin-induced inhibition of gastrointestinal transit: requirement for an intact pituitary-adrenal axis
(Elsevier, 1986-05)
The role of the pituitary-adrenal axis in the inhibition of gastrointestinal transit caused by intrathecal administration of bombesin was examined. Bombesin (0.3-10 [mu]g) slowed transit by this route in a dose-related ...
