DESCRIPTION A 7-year-old child was brought to the hyperbaric oxygen centre because of cyanosis of his glans penis. He had been circumcised the same day with the use of a monopolar electrocautery device. Unfortunately, the electrocautery caused a severe burn injury on the glans of the child. On examination, he had necrosis over the glans and shaft of the penis (figure 1). Circumcision is a relig...

Due to cost effectiveness and less electrical fault hazards, the HVDC transmission is more suitable for long distance power transmission than that for the conventional AC transmission system. Moreover the utilization of power electronics has made HVDC technology competitive and reliable in comparison to HVAC system. The controlling mechanism of the DC link (either monopolar or bipolar) is the m...

Multiple asters (MAST)/Orbit is a member of a new family of nonmotor microtubule-associated proteins that has been previously shown to be required for the organization of the mitotic spindle. Here we provide evidence that MAST/Orbit is required for functional kinetochore attachment, chromosome congression, and the maintenance of spindle bipolarity. In vivo analysis of Drosophila mast mutant emb...

OBJECT This study was performed to evaluate the reliability and utility of using monopolar impedance monitoring for estimation of the location of the thermocouple electrode during a pallidotomy procedure. METHODS In 26 patients, impedance profiles were measured at 2-mm intervals and anatomical boundaries were marked on postoperative MRI studies in 19 patients. The pattern of change in impedan...

The recently developed automated, high-throughput monopolar REIMS platform is suited for the identification of clinically important microorganisms. Although already comparable to the previously reported bipolar forceps method, optimization of the geometry of monopolar electrodes, at the heart of the system, holds the most scope for further improvements to be made. For this, sharp tip and round ...

This paper is about transfer function approaches for brain-electrode interface modelling in the context of StereoElectroEncephaloGraphy, and their possible use tissue classification (between grey white matter). Monopolar bipolar configurations are first reviewed, giving rise to nonparametric parametric identification methods, as well related results (for identical tissues distinct at measuremen...

OBJECTIVES/HYPOTHESIS To validate the sheep model for endoscopic nasal surgery, and to utilize this model to compare the immediate and early postoperative histopathologic effects of four electrosurgical turbinate reduction techniques. STUDY DESIGN Pilot comparative study of electrosurgical devices for inferior turbinate reduction using a sheep model. METHODS Three radiofrequency devices (on...

The anaphase promoting complex/cyclosome (APC/C) triggers the separation of sister chromatids and exit from mitosis across eukaryotic evolution. The APC/C is inhibited by the spindle assembly checkpoint (SAC) until all chromosomes have achieved bipolar attachment, but whether the APC/C reciprocally regulates the SAC is less understood. Here, we report the characterization of a novel allele of t...
