Created by the multiple award winning author Stephen Baxter.Įvolution begins it's story in the Cretaceous period over 65 million years ago (the age of the Dinosaurs), and just before the K–T extinction event where it is believed that an asteroid of 6 miles diameter or greater hit the earth causing a catastrophic event that led to the mass extinction of the Dinosaurs.įollowing one proto-mammal from this time period, a tiny little rat like creature called Purga (from species Purgatorius) the novel tracks the direct evolutionary path the offspring take, one single strand of DNA through the millions of years before our present time, and then off into the future. In conclusion, platelet collection with the new Amicus allows for high platelet yields of adequate quality as judged by WBC content, CD62 expression, and electron microscopic morphological changes.Evolution is a monumental tale of the very evolution of mankind, from the age of the dinosaurs to way into the distant future.

Furthermore, there was a correlation between CD62 expression and the degree of WBC contamination (P = 0.03). During the recommended 5 days storage, sequential in vitro analyses were performed in 27 units, showing limited platelet activation according to CD62 expression and morphological changes on electron microscopy (EM). The white blood cell (WBC) contamination per therapeutic unit was less than 5 x 10(6) in 91% of phereses performed in part one of the study and in 98% of phereses performed in part two. According to local policy, every collection bag was separated into two therapeutic units each containing a mean of 1.87 (1.83) x 10(11) platelets. During the second part, after a software change, the mean volume and mean procedure time were 3,071 ml and 68.3 min, respectively. During the first part of the study, the mean volume processed was 3,225 ml and the mean procedure duration 69.5 min. One hundred eighty-three single-donor plateletpheresis procedures were performed, using a collection of 4-4.5 x 10(11) platelets as endpoint. The purpose of this study was to evaluate the new AMICUS (Baxter-Fenwal Division) cell separator in terms of donor safety, efficiency, and quality of the product obtained.
