Pancreas preservation by cold storage using University of Wisconsin solution was the mainstay method used for pancreas transplantation during the past 2 decades. Other solutions, such as HTK, Celsior, and SCOT 15, could not demonstrate any advantage for short preservation periods. But the advent of clinical islet transplantation and the larger use of controlled non–heart-beating donors have pro...
With efficient tools for computing the Fourier transform in hand, in this lecture we briefly describe issues that arise when we try to use this tool to analyze signals. We will discuss two major issues. The first is the effect of only collecting a finite number of samples x[0], . . . , x[L − 1], rather than observing x[n] for all n. The second is what happens when the signal of interest has fre...
The effects of different preservation conditions (temperature 20-25 or 10-15 degrees C; duration 12 or 24 h) for ovaries of Cervus nippon yesoensis on in vitro maturation of oocytes were examined. When ovaries were kept for 12 h at 20-25 degrees C, maturation rate of oocytes was highest (71%); however, it declined when the preservation time was extended to 24 h (31%). When the preservation temp...
