apexification is a method of inducing apical closure for non-vital immature permanent teeth. during this treatment a mineralized barrier is induced [with long term calcium hydroxide (ch) treatment]; or artificially created [with mineral trioxide aggregate (mta) plug]. this article describes two cases of apexification in immature necrotic teeth treated with these two different techniques. after ...

The percent of energy consumed by plug load equipment in commercial buildings is on the rise. Research conducted in the past has included surveying plug load equipment, measuring plug load electricity consumption and equipment operating patterns, and studying plug load reduction solutions in office buildings, but plug load energy use across other building types is poorly understood. A universit...

PURPOSE To report a case of extrusion of a new soft punctum plug with thermoexpansion property (Medennium SmartPLUG). METHODS A soft punctum plug was implanted in a 32-year-old woman with a severe dry eye syndrome in juvenile arthritis. RESULTS One week after implant the plug partially extruded outside the punctum. Despite this adverse event, all subjective dry eye symptoms improved. CONC...

Arabinogalactan proteins (AGPs) are implicated in cell expansion by unknown mechanisms, thus AGP content and cell-expansion rate might be correlated. We used Yariv reagent to quantify release rates and distribution of AGP at the cell surface of tobacco BY-2 cells: plasma membrane (M); soluble periplasmic AGPs released by cell rupture (S); cell wall (W); and growth medium (Gsink). In contrast to...

Software component architectures allow assembly of applications from individual software modules based on clearly defined programming interfaces, thus improving the reuse of existing solutions and simplifying application development. Furthermore, the plug-in programming paradigm additionally enables runtime reconfigurability, making it possible to adapt to changing application needs, such as di...

Spamato is an extendable, collaborative spam filter system written in Java that combines different filter technologies to provide more accurate results. This thesis takes Spamato a big step further by introducing a plug-in architecture. Users and developers can now customize their system by adding, updating, and removing plug-ins. The underlying plug-in architecture is completely independent of...

Proteins are translocated across membranes through a channel that is formed by the prokaryotic SecY or eukaryotic Sec61 complex. The crystal structure of the SecY channel from M. jannaschii revealed a plug domain that appears to seal the channel in its closed state. However, the role of the plug remains unclear, particularly because plug deletion mutants in S. cerevisiae are functional. Here, w...
