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 ...
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 ...
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 ...
Measurement of ammonia and glutamine in cell culture media by gas sensing electrodes
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-04)
This paper describes the use of a commercially available off-line gas sensing electrode for determination of ammonia and glutamine in cell culture media. The measurement technique was tested in different media preparations ...
A novel and efficient synthesis of the naturally occurring nucleoside doridosine
(Elsevier, 1985)
1-Methylisoguanosine was synthesized by a one-pot reaction involving a condensation of 5-amino-1-([beta]--ribofuranosyl)imidazole-4-carboxamide (1) with methyl isothiocyanate, treatment of the resulting thiourea derivative ...
Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
Characterization of a circular thin film plasma source for atomic emission spectroscopy
(Elsevier, 1985)
A plasma source for analytical atomic emission spectroscopy is described based on the electrical vaporization by capacitive discharge of a thin Ag film deposited on a polycarbonate membrane filter. The source is designed ...
Two-particle continuous-time random walks and binary reactions in disordered media
(Elsevier, 1984-02-10)
The relation between unary-(trappihg) and binary (mutual annihilation) reactions in disordered systems is studied in the framework of the continuous-time random walk. It is found that if the waiting-time distribution of ...
