(1) The patterns observed were: clusters of granules related to the cell membrane; positive staining localized to portions of the cell membrane, and, less commonly, the whole cell circumference.
(2) The extrusion of granules into the intercellular space via exocytosis is frequently observed.
(3) We have previously shown that serotonin is present in secretory granules of frog adrenochromaffin cells; concurrently, we have demonstrated that serotonin is a potent stimulator of corticosterone and aldosterone secretion by adrenocortical cells.
(4) Finally, it could be observed that elevated osmotic pressures reduced the lysis of isolated secretory granules when bicarbonate ions were present in the incubation medium.
(5) In addition, transitional macrophages with both positive granules and positive RER, nuclear envelope, negative Golgi apparatus (as in exudate- resident macrophages in vivo), and mature macrophages with peroxidatic activity only in the RER and nuclear envelope (as in resident macrophages in vivo) were found.
(6) They had no endocrine-like granules and were not associated with nerves or basement membranes.
(7) Electron microscopic immunohistochemistry revealed histamine-immunostaining in granules in a small number of nerve fibers and varicosities.
(8) Results of detailed studies on tissue reactions to Cysticercus bovis in the heart of cattle, together with a comparison of findings in animals with spontaneous and experimental infection, and an evaluation of tissue reactions in relation to the location, morphology and morphogenesis of C. bovis provided evidence for the fact that in general, the response of the heart to the presence of C. bovis was an inflammatory reaction characterized by the origin of a pseudoepithelial border and a zone of granulation tissue.
(9) The presence of a previously unreported dipeptide transport mechanism within blood leukocytes and the selective enrichment of the granule enzyme, DPPI, within cytotoxic effector cells of lymphoid or myeloid lineage appear to afford a unique mechanism for the targeting of immunotherapeutic reagents composed of simple dipeptide esters or amides.
(10) The volume density of glycogen granules in hepatocytes was highest 4 hr after the secretory granules of B cells showed the lowest value.
(11) A new technique to obliterate the mastoid volume or to reduce an old cavity by means of hydroxyapatite granulate is presented.
(12) The data suggest that proinsulin, normally processed in secretory granules and released via the regulated pathway, may also be processed, albeit less efficiently, by the constitutive pathway conversion machinery.
(13) In telecost fishes, the corpuscles of Stannius contain Bowie-stainable granules and a renin-like pressor substance.
(14) Electron microscopy revealed a well-developed rough endoplasmic reticulum, an enlarged Golgi apparatus and many highly electron-dense secretory granules resembling those of Clara cells.
(15) The study confirms that secretin influences pancreatic protein secretion and indicates in addition, that pharmacologic doses of the hormone, have the capacity to block acinar cell zymogen granule release.
(16) Immunoreactions of LTR which were seen in specific granules of neutrophils and monocytes attached to the endothelial cell surface may indicate the onset of endothelial cell damage.
(17) The capacity of granule-cell networks to separate overlapping patterns of activity on their inputs is adequate, with spatial variability in the secretion at synapses, but is improved if there is also temporal variability in the stochastic secretion at individual synapses, although this is at the expense of reliability in the network.
(18) These results suggest that bPAG is probably synthesized by trophoblast binucleate cells and stored in granules prior to delivery into the maternal circulation after cell migration.
(19) CAM, especially CD11c, were also detected in cytoplasmic granules by immunostaining in IL2-activated NK cells.
(20) The outstanding morphologic feature of cortical cells exposed to microunit ACTH concentrations for 40 min was the abundance of electron-dense granules (0.2-0.4 mum).
Photosphere
Definition:
(n.) A sphere of light; esp., the luminous envelope of the sun.
Example Sentences:
(1) Being more than 1,000C colder than the 5,500C of most of the visible Sun's surface, the photosphere, they are darker and stand out by contrast.
