ET-1 did not correlate with biochemical or morphological markers of myocardial injury or change of left ventricular ejection fraction (LV-EF) but good linear correlation between max logET-1 and max logCRP was found (r=0.44, P=0.0002). ET-1 rise is more pronounced in on-pump CABG and ET-1 production could be driven by periprocedural inflammatory reaction. (C) 2011 Published by European Association for Cardio-Thoracic Surgery. All

“This study aimed at analysing the utilization of an electronic nose (e-nose) to serve as a specific monitoring tool for anaerobic digestion process, especially for detecting organic overload. An array of non specific metal oxide semiconductor gas sensors were used to detect process faults due to organic overload events in twelve 1.8-L anaerobic semi-continuous reactors. SHP099 Three different load strategies
were followed: (1) a cautious organic load (1.3 gVS L-1 day(-1)); (2) an increasing load strategy (1.3-5.3 gVS L-1 day(-1)) and (3) a cautious organic load with load pulses of up to 12 gVS L-1 day(-1). A first monitoring campaign was conducted with three different substrates: sucrose, maize oil and a mix of sucrose/oil during 60 days. The second campaign was run with dry sugar beet pulp for 45 days. Hotelling’s T (2) value and upper control limit to a reference set of digesters fed with a cautious OLR (1.3 gVS L-1 day(-1)) was used as indirect state variable of the reactors. Overload situations were identified by the e-nose apparatus with Hotelling’s T (2) values at least four times higher in magnitude than the upper control limit of 23.7. These results confirmed that the e-nose technology appeared promising see more for online detection of process imbalances in the domain of anaerobic
digestion.”
“Background: The objective was to clarify the role of hepatic arterial embolization (AE) in the management of blunt hepatic trauma.
Methods: Retrospective observational study of 183 patients with blunt hepatic trauma admitted to a trauma referral center over a 9-year period. The charts of 29 patients (16%) who underwent hepatic angiography were reviewed for demographics, injury specific data, management strategy, angiographic indication, efficacy and complications of embolization, and outcome.
Results: AE was performed in 23 (79%) of the patients requiring angiography. Thirteen patients managed conservatively underwent emergency embolization after preliminary computed tomography scan. Six had postoperative embolization after damage control laparotomy and four had delayed embolization. Arterial bleeding was controlled in all the cases.
