Morphodynamic study of the corona mortis using the SimLife technology.

Purpose: Open book pelvic ring fractures are potentially life-threatening, due to their instability and major hemorrhage risk. During the open reduction and internal fixation, the pelvic approach remains a technical challenge, as the surgeon wants to prevent any iatrogenic damage of the vascular loop located in the retro-pubic area called corona mortis (CMOR). Recently, the cadaver perfused SimLife technology has been developed to improve the surgeon training, out of the operating room.

Persistent swallowing disorders after extubation in mechanically ventilated patients in ICU: a two-center prospective study.

Background: Persistent swallowing disorders (SD) are non-pulmonary complications of mechanical ventilation (MV). However, there are few clinical studies on persistent SD in critically ill patients undergoing tracheal intubation for MV. The aim of the present study was to assess the incidence and characteristics of clinical manifestations associated with persistent SD.

On the control of copper colloidal distribution by humic substances in the Penzé estuary.

In this study, we investigated the variations of colloidal Cu in a temperate macrotidal estuarine system (Penzé, NW France). The originality of this work resides on examining seven colloidal/dissolved fractions at seven different periods of the year whereas previous studies on estuaries generally considered two or three fractions and were focused on a unique survey. A high proportion of Cu (∼90%) was generally found as colloids (5 kDa-0.

Determination of ultra-trace Sb(III) in seawater by stripping chronopotentiometry (SCP) with a mercury film electrode in the presence of copper.

This work reports the determination of ultra-trace of Sb(III) in seawater by using a stripping chronopotentiometric (SCP) method with a mercury film electrode. A sensitivity and detection limit of 360 ms L microg(-1) and 8 ng L(-1) (70 pM), respectively, were accomplished for a 15-min electrolysis time. Compared to the only two chronopotentiometric methods reported for Sb(III) determination in seawater, our method is more sensitive and does not need to use a medium exchange procedure before the stripping step.
