(n.) A large vesicle or bulla, usually containing a serous fluid; a blister; a bubble, as in water, glass, etc.
Example Sentences:
(1) It has been shown by LM and transmission electron microscopy that cells with blebs are viable and capable of mitotic activity.
(2) Transmission electron microscopy demonstrated that these blebs were devoid of organelles and microvilli; scanning electron microscopy revealed that the blebs were highly wrinkled and more numerous than were the projections observed in tissue from animals treated with testosterone alone, or in tissue from unoperated controls.
(3) Combined SEM and TEM examination of the endothelium of compressed segments revealed "craters" and "balloons", blebs and vacuoles, swollen mitochondria, dilated granular endoplasmic reticulum, and subendothelial edema.
(4) Ten filtrating blebs remained after a 5 months' follow-up period.
(5) These early hyperplastic lesions revealed stellate-shaped dilated bile canaliculi lined by blebs and abnormally thick elongated microvilli, a decreased number of microvilli on the sinusoidal surface, a marked increase in smooth endoplasmic reticulum, large nucleoli, and bundles of pericanalicular microfilaments.
(6) Thus, encapsulation of the filtering bleb, although requiring additional surgery in many cases, carries a favorable long-term prognosis.
(7) These mitochondria had a highly electron dense matrix and protrusions or blebs of mitochondrial outer membrane were frequently observed.
(8) An increase of cytosolic free Ca2+ is not the stimulus for bleb formation or the final common pathway leading to cell death.
(9) We recommend this skin incision for young patients with pneumothorax if the chest CT scan confirms that the bullae or blebs are localized to the apex of superior segment of the lower lobe.
(10) They induced modifications in particle distribution, a blebbing of particle-free areas and the appearance of lamellar figures on the plasma membrane of fungus cells.
(11) 2 Treatment of hepatocytes with either NABQI (0.4 mM) or paracetamol (2 mM) alone resulted in a considerable loss of cell viability, as assessed by trypan blue exclusion or leakage of lactate dehydrogenase, accompanied by an increase in the percentage of viable cells that were blebbed.
(12) Experiments where catalase was used to interrupt H2O2 exposure over a long time course revealed 15-30 minutes to be the critical period of exposure to 5 mM H2O2 necessary for a sustained increase in F actin as well as large increases in membrane blebbing and later cell death.
(13) None of the patients treated by operation (plication or resection and suture of the bleb) had a later recurrence.
(14) We have found the early placement of a therapeutic bandage contact lens permits extended administration of 5-FU during this period, minimizing discomfort and inflammation as well as enhancing bleb survival.
(15) Scanning electron microscopy showed the appearance at the culture surface of immature cells with gross surface abnormalities including large numbers of blebs, stubby microvilli and long pleomorphic microvilli.
(16) Vascular changes included perivascular deposits of proteinaceous material presumably from leakage of serum proteins, variable electron lucency of endothelial cell cytoplasm, an apparent increase in pinocytotic vesicles, rare platelet thrombosis of capillaries, and rare intravascular blebs of luminal plasma membrane.
(17) Formation of blebs was dose dependent and preceded release of LDH and trypan blue uptake.
(18) In addition, CHO cells displayed membrane bleb formations similar to those found in CHO cells after exposure to established inhibitors of protein synthesis, puromycin and anisomycin.
(19) The surfaces of the majority of these cells are covered by vesicles or blebs.
(20) In this group, 4 cases bled again because of enlargement or the development of an aneurysmal bleb.
