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 ...
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 ...
Progress in modeling heat capacity versus temperature morphology
(Elsevier, 1986-12-15)
After discussion of other models for representing heat capacities, the volumetric model used in resolution of lanthanide Schottky contributions over the cryogenic range and a more recent single-parameter formula to represent ...
Kinetic comparisons of amniotic fluid inactive renin and renal renin using synthetic and human renin substrates
(Elsevier, 1986-12)
Inactive renin has been isolated from pooled amniotic fluid and purified ~642-fold. Prior to activation the isolates has ~4% of the activity found after activation. The observation is similar to that reported for inactive ...
Detection of electrophoretically silent mutations by immobilized pH gradients
(Elsevier, 1986)
The detection of neutral amino acid mutants, by isoelectric focusing in immobilized pH gradients (IPGs), is exemplified by the separation of hemoglobin (Hb) Beirut (126[beta] Val --> Ala) from Hb A in a shallow pH 7.2-7.6 ...
Excited state spectroscopy of para di-substituted benzenes in a supersonic beam using resonant two photon ionization
(Elsevier, 1986)
Excited state vibronic spectra of p-aminophenol, p-cresol, p-fluoroaniline, p-fluorophenol, hydroquinone and p-toluidine have been obtained using resonant two photon ionization supersonic beam mass spectrometry. Despite ...
Intramolecular azide-diene cycloadditions. An approach to fused bicyclic 3-pyrrolines based on a one-pot nitrene-diene cycloaddition equivalent.
(Elsevier, 1986)
Cyclization of heterosubstituted [omega]-azidodienes 11 provides fused bicyclic 3-pyrrolines 12 in one operation. These pyrrolines are potentially useful intermediates for natural products synthesis, as illustrated by ...
Far-infrared and Raman spectra of pseudo -tetrahedral complexes of ethylenedimorpholene
(Kluwer Academic Publishers; VCH Verlagsgesellschaft mbH ; Springer Science+Business Media, 1986-11)
The far-i.r. and Raman spectra of a closely related group of pseudo -tetrahedral complexes of general formula [MX 2 EDM] are reported (M = Co II , Ni II , Cu II , Zn II ; X = Cl or Br). EDM, ethylenedimorpholene, acts in ...
Evaluation of plasma 3-methoxy-4-hydroxyphenylglycol
(Elsevier, 1986)
A high-performance liquid chromatographic (HPLC) assay suitable for the evaluation of 3-methoxy-4-hydroxyphenylglycol (MHPG) in 1-ml aliquots of plasma is presented. Preparatory steps include extraction into ethyl acetate ...
