Available in PDF, EPUB and Kindle. Book excerpt: Since accidentally discovering the ability of glycerol on protecting cells from freezing damage, many researchers have been pursuing to develop cryopreservation methods of a very wide range of cells and some tissues, and these have found widespread applications in biology and medicine. From the point of view of living organisms, cryopreservation is a useful tool for ex situ conservation of genetic resources together with its contribution on conservation of their biodiversity. Cryopreservation in Eukaryotes includes totally 12 chapters, which have been written by the expert researchers in the field. The chapters are a comprehensive collection of the most frequently used methods for eukaryotes. With this book, every researcher will better understand the principles, background, and current status of cryopreservation in particular organisms.

Book Synopsis Effect of Different Equilibration Periods Pre-cryopreservation on Post-thaw Sperm Motility in Nguni and Boran Bulls by : Elizabeth Van Staden
Download or read book Effect of Different Equilibration Periods Pre-cryopreservation on Post-thaw Sperm Motility in Nguni and Boran Bulls written by Elizabeth Van Staden and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to natural selection, the use of artificial insemination (AI) and other reproductive technologies rapidly increase the rate of genetic change in any population. In order to achieve success with AI, the semen used to inseminate cows must be of the highest possible quality. When semen is frozen, generally only about 50% of the spermatozoa survive the cryopreservation process. Thus, any factors possibly affecting the survival of spermatozoa through the numerous freezing-thawing steps should be studied, in order to identify the optimal conditions for the survival of spermatozoa. The discovery of protective agents within egg yolk and glycerol was a major milestone in sperm cryopreservation. These agents protect bovine spermatozoa during cooling and freezing procedures and result in increased survival rates. Cryopreservation of spermatozoa has become the most common technique for the preservation of male fertility of genetically superior sires even after their death. Using cryopreserved sperm to artificially inseminate females has become standard practice in commercial dairy cattle herds and the application of this reproductive management tool is also expanding to beef herds worldwide. The use of glycerol as a cryoprotectant for bovine spermatozoa is credited as the reason for the success in bovine semen cryopreservation. The purpose of this research was to quantify the effects of different cooling periods, as well as different glycerol equilibration periods on the post-thaw motility percentages and recovery fractions of semen collected from Boran and Nguni bulls. The research was subdivided into two experiments. In each experiment different cooling and glycerol equilibration times were researched. The first experiment involved shorter cooling times (30, 60, 120 and 240 minutes) with each cooling time followed by several longer equilibration times (4, 5, 6, 7 and 8 h). In the second experiment the cooling and equilibration times from the first experiment were reversed. This resulted in longer cooling times (4, 5, 6, 7 and 8 h) with each cooling time having shorter glycerol equilibration times (30, 60, 120 and 240 minutes). An egg yolk-Tris two-step extender was used in both the experiments. The general trend for the glycerol equilibration periods studied in Experiment 1 was that the resulting overall average post-thaw motility percentage and average recovery fraction increased with longer periods. There was a breed difference when comparing the average post-thaw motility percentages after 4, 5, 6 and 8 h (p

Book Synopsis Current Frontiers in Cryobiology by : Igor Katkov
Download or read book Current Frontiers in Cryobiology written by Igor Katkov and published by BoD – Books on Demand. This book was released on 2012-03-09 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost a decade has passed since the last textbook on the science of cryobiology, Life in the Frozen State, was published. Recently, there have been some serious tectonic shifts in cryobiology which were perhaps not seen on the surface but will have a profound effect on both the future of cryobiology and the development of new cryopreservation methods. We feel that it is time to revise the previous paradigms and dogmas, discuss the conceptually new cryobiological ideas, and introduce the recently emerged practical protocols for cryopreservation. The present books, "Current Frontiers in Cryobiology" and "Current Frontiers in Cryopreservation" will serve the purpose. This is a global effort by scientists from 27 countries from all continents and we hope it will be interesting to a wide audience.
