In 1953, the first successful induction of cancer in a laboratory animal with a tobacco product was reported with the application of cigarette tara to mouse skin (Wynder et al., 1953). The particulate matter of cigarette smoke generated by an automatic smoking machine was suspended in acetone (1:1) and painted onto the shaven backs of mice three times weekly for up to 24 months. A clear dose re...

Objective: hepatocellular carcinoma (HCC) ablation by radiofrequency (RFA) is a novel technique with a great variety of methods whose efficacy and predictive factors have not been completely studied. Some of the main predictive factors in this type of treatment are analyzed in the present study. Patients and methods: ninety-three patients with hepatocellular carcinoma over cirrhosis, and with n...

Enumerative distributed reachability analysis based on a simple partitioning of the state space has become a well known technique implemented in numerous model checking tools. The timed automata model checker UPPAAL is no exception to this rule, and for over 5 years a distributed version of UPPAAL has been used to analyse large timed automata models. In this talk we address two fundamental issu...

OBJECTIVES/HYPOTHESIS To test our hypothesis that high-surgeon volume is associated with improved surgical efficiency and 30-day outcomes, and lower hospital utilization. STUDY DESIGN Retrospective observational cohort, 2008-2013. METHODS A total of 3,135 patients with hemithyroidectomy or total thyroidectomy performed by a high-volume surgeon, propensity score-matched to 3,135 patients wit...
