Livers cold preserved during variable periods of ischemia suffer functional, morphological and hemodynamic alteration, which are exacerbated when they are reperfused. One important injury is glycogen depletion during cold ischemia/ reperfusion. How liver can restore their energy during reperfusion is related with the preservation time, nutritional status of the donor, and the preservation solut...

Digital preservation aims at maintaining digital objects accessible over long periods of time, ensuring the authenticity and integrity of these digital objects. In this paper, we propose three different approaches to address the digital preservation problem. First, we survey the main requirements specific to the preservation arena. Next, we show how digital preservation can be approached as a s...

PURPOSE To determine the histological and biomechanical characteristics of glycerol-preserved human sclera. METHODS A total of 114 paired human sclerae were cleaned and preserved with 98% glycerol under refrigeration at 4 to 8 degrees C. The samples were divided into a control group with no preservation and 5 groups of 19 sclerae in 7, 15, 30, 90 and 180 days of preservation. Each specimen wa...
