Pseudomonas aeruginosa exposed to silver sulfadiazine (AgSu) were examined in an electron microscope. The treated cells were distorted in shape, and structures (blebs) protruded from the cell surface. These "blebs" appeared to arise from the cell wall. A strain of P. aeruginosa resistant to AgSu did not display these changes. Upon exposure of P. aeruginosa to silver nitrate, none of these chang...

Long asters rock the spindle M itotic cells regulate the lengths of their astral microtubules to keep the spindle steady during cytokine-sis, Rankin and Worde-man report. Astral microtu-bules emanate from the spindle poles toward the cell cortex and help to position the cleavage furrow at the end of mitosis by confi ning actomyosin contraction to the cell equator: when microtubules are shortene...

Five leaking filtering blebs, occurring between 10 months and 21 years after trabeculectomy, were closed with cyanoacrylate tissue adhesive. Filtering bleb integrity was preserved in four cases, so that additional microsurgery was avoided. The only problem associated with use of tissue adhesive was the development of corneal abrasions in three cases. Although it is an accepted treatment for the...

Blebs are balloon-shaped membrane protrusions that form during many physiological processes. Using computer simulation of a particle-based model for self-assembled lipid bilayers coupled to an elastic meshwork, we investigated the phase behavior and kinetics of blebbing. We found that blebs form for large values of the ratio between the areas of the bilayer and the cytoskeleton. We also found t...

AIM To describe a novel technique to treat hypotony and shallow anterior chamber following trabeculectomy METHODS Three patients who underwent fornix based trabeculectomy with mitomycin C (MMC) presented in the postoperative days with a shallow anterior chamber, hypotony, and overfiltrating blebs. They were treated with an injection of 0.2 ml of 16% perfluoropropane (C(3)F(8)) to the anterior...

After treatment with aminoglycoside antibiotics, Escherichia coli B and Pseudomonas aeruginosa P28 showed numerous blebs on the cell wall surface.
