Recent studies clarifying the closest relatives of the world's largest flowers, Rafflesiaceae, whose floral diameters range from approximately 11 to approximately 100 cm, indicated that they evolved from tiny-flowered ancestors in a burst of floral gigantism. New data now suggest that floral size evolution within Rafflesiaceae may be more dynamic ...

Although suction-assisted liposuction under tumescent anesthesia remains the traditional method for body sculpting, newer technologies promise to increase efficiency, decrease surgeon fatigue, and minimize complication. Power-, ultrasound-, and laser-assisted devices are ideal in large volume cases and in areas of fibrous tissues as an adjunct to traditional liposuction. Although skepticism ...

Myopotential oversensing in implantable defibrillators causing inhibition of pacing and inappropriate therapies is well described. Current literature is dominated by reports of diaphragmatic muscle as the source of such far-field oversensing. Those reporting pectoral muscle sources were invariably due to unipolar sensing circuits, incorrect DF-1 connections or inappropriate programming. We ...

Two cases are reported of inappropriate implantable cardioverter-defibrillator shocks due to external alternating current leak. Electromagnetic interference (EMI) can mimic cardiac signals and cause inappropriate implantable cardioverter-defibrillator (ICD) shocks. EMI can arise from the normal functioning of electrical appliances or from alternating current leak. The two cases had inappropriate ICD ...
