(9) At 24 or 48 hours after ischemia, 63Ni, 99TcO4, and 22Na were preferentially concentrated in the damaged striatum and hippocampus, whereas 65Zn, 59Fe, 32PO4, and 147Pm did not accumulate in irreversibly injured tissue.
(10) Aside from these characteristic findings of HCC, it was important to reveal the following features for the diagnosis of well differentiated type of small HCC: variable thickening or distortion of trabecular structure in association with nuclear crowding, acinar formation, selective cytoplasmic accumulation of Mallory bodies, nuclear abnormalities consisting of thickening of nucleolus, hepatic cords in close contact with bile ducts or blood vessels, and hepatocytes growing in a fibrous environment.
(11) They are capable of synthesis and accumulation of glycogen and responsible for its transfer to sites of more intense metabolism (growth, bud, blastema).
(12) Our results show that large complex lipid bodies and extensive accumulations of glycogen are valuable indicators of a functionally suppressed chief cell in atrophic parathyroid glands.
(13) Much information has accumulated on the isolation and characterization of a heterogeneous group of molecules that inhibit one or more of the bioactivities of interleukin 1.
(14) The mechanism by which K+ accumulates in the follicle was insensitive to ouabain, so that a typical Na+, K(+)-ATPase mechanism does not appear to be involved.
(15) The data shows a dissociation between ferritin synthesis, cellular accumulation and secretion for which the mechanisms have still to be elucidated.
(16) The rate of accumulation was highest late in infection and only the slower migrating form incorporates significant amounts of glucosamine.
(17) Initiation of the alternative pathway by the cryptococcal capsule is characterized by a lag in C3 accumulation and the appearance of a limited number of focal initiation sites which resemble those observed when the alternative pathway is activated by zymosan and nonencapsulated cryptococci.
(18) Accumulating evidence indicates that for most tumors, the switch to the angiogenic phenotype depends upon the outcome of a balance between angiogenic stimulators and angiogenic inhibitors, both of which may be produced by tumor cells and perhaps by certain host cells.
(19) The aim of our experiments was to investigate firstly whether during an acute inflammatory process platelets accumulate in the inflamed area and secondly whether the inflammation has an effect on the properties of the platelets.
(20) The accumulated evidence would strongly favor an affirmative answer.
Aggregation
Definition:
(n.) The act of aggregating, or the state of being aggregated; collection into a mass or sum; a collection of particulars; an aggregate.
Example Sentences:
(1) Aggregation was more frequent in low-osmolal media: mainly rouleaux were formed in ioxaglate but irregular aggregates in non-ionic media.
(2) We have examined overlapping octapeptides from the kappa IIIb light chain variable region and show that some framework peptides have the ability to bind aggregated IgG.
(3) Platelet-rich plasma (PRP) was prepared, and platelet aggregation studies were conducted directly or conducted on washed platelets prepared from PRP collected with ACD.
(4) Macrophages internalize aggregated low density lipoprotein (LDL) by LDL receptor-dependent phagocytosis.
(5) Cicaprost is an orally available analogue of PGI2 and has been shown to inhibit platelet aggregation in both in vitro and animal studies.
(6) Only IgG2a and IgG2b myeloma proteins bound readily to IC-21 Fc-receptors, the former in nonaggregated as well as aggregated form, the latter only as aggregated complexes.
(7) When the aggregates occurred on the cell periphery their position coincided with areas free of lamellae.
(8) 2-(4'-Isobutylphenyl)propionic acid, ibuprofen, is an antiinflammatory agent which possesses moderate platelet aggregation inhibitory activity.
(9) In addition, spontaneous platelet aggregation is increased when vegetations are present on cardiac valves.
(10) At concentrations several hundredfold higher than the equivalents present in the minimum concentration of rat skin soluble collagen required for platelet aggregation, neither Hyl-Gal (at 29 muM) nor Hyl-Gal-Glc (at 18 muM) caused platelet aggregation or inhibited platelet aggregation by native collagen.
(11) The mechanisms leading to spontaneous platelet aggregation and thrombocytopenia appear to be similar to those described for other patients with type IIB vWD.
(12) There is approximately a 25% decrease in aggregation from regions of the rib distal to the metaphyseal-growth plate junction (69%) to the region proximal to it (50%).
(13) Laboratory data were aggregated similarly within each study, using the last active drug as a grouping factor.
(14) No correlation could be found between DS content and state of aggregation.
