BACKGROUND AND PURPOSE Recent reports describe a high rate of thromboembolic events related to Guglielmi detachable coil (GDC) use in the treatment of cerebral aneurysms. The purpose of this study was to investigate electrolysis-related changes of blood as a potential cause of thromboembolic complications associated with GDC use. METHODS For in vitro observations, 15 GDCs (10 conventional coi...

PURPOSE To report a case of complex Descemet's membrane detachment (DMD) and tears during phacoemulsification cataract surgery. CASE REPORT A 64-year-old woman underwent phacoemulsification surgery in her right eye and developed tears and partial loss of Descemet's membrane (DM) while the aspiration port was inserted through the main incision. Massive corneal edema obscured the view and the a...

Removal of gas bubbles from the electrode surface is practically important to maintain activity electrochemical evolution reactions. Conventionally, most studies have focused on development electrocatalysts and paid less attention bubble removal issues. Recently, it has been reported that attached can be readily eliminated by imparting extremely gas-repellent properties (so-called superaerophob...

This study was performed to assess the binding kinetics of a targeted microbubble contrast agent exposed to shear stress. An ultrasound contrast targeted to P-selectin was designed by conjugating monoclonal antibodies against murine P-selectin (RB40.34) to the lipid monolayer shell of the microbubble using poly(ethylene glycol)-biotin-streptavidin. The attachment and detachment of targeted micr...

The characteristics of bubble motion in non-Newtonian liquids are still not well understood because many parameters influence the terminal rise velocity, trajectory and shape of bubbles (Frank, 2003). As the bubble motion is a complex problem, the degree of the complexity increases with bubble size (Kulkarni and Joshi, 2005). When bubble rises through liquid, the most resistance will be imposed...

Boiling, a dynamic and multiscale process, has been studied for several decades; however, a comprehensive understanding of the process is still lacking. The bubble ebullition cycle, which occurs over millisecond time-span, makes it extremely challenging to study near-surface interfacial characteristics of a single bubble. Here, we create a steady-state vapor bubble that can remain stable for ho...

The authors investigate the relationship between individual attributes and support for municipal detachment by analyzing a recent survey of Los Angeles voters. In this survey, San Fernando Valley residents were asked whether they favored detachment from Los Angeles and reorganization as a separate city. Multinomial logit regression results indicate that support for detachment is influenced by d...

Abstract The stresses existing in power transformers lead to the generation of bubbles. They are primary source that worsens and leads insulation failure. Due complexity bubble dynamics, it is challenging figure out mechanisms. However, creation, migration, accumulation mechanisms require further explanation. A set experiments has been conducted provide a scientific overview results revealed bu...
