Therefore, an inline monitoring device for terminating ... read more
08. May 2012 | Hepatic ischemia/reperfusion (I/R) injury occurs in a variety of clinical scenarios, including transplantation, liver resection, trauma, and hypovolemic shock. The molecular mechanisms causing liver injury after I/R have been subject of several studies, which revealed a series of complex interactions of various participant inflammatory pathways (Walsh et al., 2009; Zwacka et al., 1998a). The process of hepatic I/R-injury can be divided into two phases; an acute phase (the first 6 h after reperfusion) ... read more

01. October 2011 | Extraction of active ingredients using supercritical CO2 - Solvents are usually inorganic or organic liquids which are able to extract other gaseous, liquid or solid substances from a mixture. Moreover inert gases are conceivable as solvents. To be effective as a solvent a liquid like density has to be induced at increased pressures. Especially for the separation of sensitive functional substances for pharmaceutical purposes or for foodstuff the gentle extraction process with supercritical CO2 is applied ... read more
01. May 2011 | N. Igl-Schmid, A. Wuzik | Innovations in Food Technology, May 2011 |  The separation of substances from natural materials to obtain standardized products plays a pivotal role in food technology. Traditionally organic solvents were used for extracting compounds from a mixture. It is hard to imagine that gases could also take over this challenge. However this process has been a reality on an industrial scale for several decades. To convert gasses into effective solvents a liquid like density has to be created ... read more
