(17) It is thus probable that secondary lysosomes become part of the macrophage vesicle.
(18) The response is dose dependent for LPA concentrations from 10(-8) to 10(-3) M. Incubation of oocytes in LPA does not induce germinal vesicle breakdown.
(19) Caffeine and 6-methylaminopurine riboside (6-N-methyladenosine differentially inhibit uptake of radioactivity from adenosine and inosine, and thus the vesicles apparently possess seperate transport systems for uptake of radioactivity from purine nucleosides and from uridine.
(20) The mean length of the seminal vesicles was 2.98 cm.
Vesiculation
Definition:
(n.) The state of containing vesicles, or the process by which vesicles are formed.
Example Sentences:
(1) The breaking up of the microtubular cytoskeleton is followed by vesiculation of the rough endoplasmic reticulum and partial atrophy, as well as dispersion of the stacks of Golgi cisternae.
(2) Moderate pulmonary edema, characterized by substantial fluid cuffing around extra-alveolar arteries and veins and by fluid accumulation restricted to the thick sides of the alveolar septa, is associated with increased vesiculation in alveolar vessel endothelium.
(3) Vesiculation and stripping of myelin by mononuclear cell processes were seen as mechanisms of myelin break-down.
(4) At the ultrastructural level, all three toxins caused dose-dependent vesiculation of rough endoplasmic reticulum, formation of concentric whorls composed of rough-ER, mitochondrial swelling, large cytoplasmic vacuoles and altered bile canaliculi.
(5) The high incidence of chronic vesiculities and postinflammatory obstruction is attributed to underlying bilharziasis.
(6) Pancreatic islets, newly formed in vitro were incubated in the presence of streptozotocin (STZ; 0.4 mM) for up to 6 h. Ultrastructural changes first appeared between 2 and 4 h; heterochromatization, was followed by swelling of nuclear and reticular membranes, vesiculation of the Golgi apparatus, fragmentation of cell membranes and finally mitochondrial destruction.
(7) Seventy-two hours p.i., the cellular secretory system of infected PC12 cells showed degenerative changes with vesiculation, disorganization, and dispersion of the Golgi complexes and fragmentation, focal cystic dilation, and dissolution of the RER in the same manner as those seen in the secretory system of JE-virus-infected neurons in the mouse brain.
(8) A variety of chemicals that share the common ability to bind to free sulfhydryl groups have been shown to act as membrane vesiculants as a result of their apparent ability to induce a unique form of cell injury which results in the shedding of cell surface vesicles.
(9) For PMS-treated RBCs, there is a strong correlation between membrane protein thiol oxidation and vesiculation temperature (r = .977, P less than .001).
