One hundred consecutive robotically assisted cholecystectomies by one surgeon without any conversions to an open technique.

Between June 2010 and December 2012, one surgeon performed 100 consecutive robotically assisted laparoscopic cholecystectomies without any conversions to an open technique. To our knowledge, this is the largest single-surgeon series of robotic cholecystectomies in the literature and, because of the zero percent conversion rate, also provides evidence that robotic cholecystectomies have a clinical advantage over traditional laparoscopic cholecystectomies.

Mercury determination by cold vapor atomic absorption spectrometry utilizing UV photoreduction.

A method for the determination of mercury via UV photoreduction has been investigated. Mercury vapor was generated by the reduction of mercury species in an acetic acid solution using UV radiation. Detection of the volatile mercury was accomplished by atomic absorption spectrometry.
