Download and read online ebook Ovum Humanum write by Landrum Brewer Shettles. This book was released on 1960. Ovum Humanum available in PDF, EPUB and Kindle. Ovum humanum, while in essence an atlas of photographs of egg cells, also includes brief textual descriptions of Shettles’ experience compiling his photos and the methods he used. Shettles describes the many late nights he spent in the dark room of Columbia Presbyterian Hospital over a period of six years photographing eggs, obtained from his various patients at Columbia Presbyterian, at different stages of development both prior to as well as after fertilization. Shettles also describes the tools he used to capture these photographs, which included a Zeiss phase contrast microscope to which he attached a Leica camera. This setup provided unparalleled viewing and photographic documentation of the egg cells that Shettles compiled for his book. Shettles reports that during the six years he took photographs of over one thousand human egg cells in order to create a comprehensive compilation of these photographs. Once published, many of the book’s readers viewed the photographs as equally significant as both scientific reference material and artwork. Many of the photos contain shapes and images that would later be compared to photographs of outer space as well as more familiar images like animals and faces.

Download and read online ebook Human Oocytes and Their Chromosomes write by B.-M. Uebele-Kallhardt. This book was released on 2012-12-06. Human Oocytes and Their Chromosomes available in PDF, EPUB and Kindle. The last decade has seen remarkable advances in human ge netics. Once the correct chromosome number of the human genome was ascertained, a wide variety of diseases was rec ognized as due to numerical chromosome anomalies. There followed the discovery that spontaneous abortions are the result of chromosome errors, and specific band patterns of chromosomes allowed identification of minute lesions. The techniques of cell hybridization now allow specific gene assign ment to chromosomes and even to distinct loci on their arms. All this was possible because of the ease with which metaphase chromosomes can be obtained and manipulated. The much older technique of analysis of meiotic chromosomes has taken a back seat in this exciting era. Being much less readily accessi ble, spermatogonial analysis is much less frequently under taken and is less successful. Even more difficult for study is the female meiotic process. Not only is meiosis extraordinar ily long, spanning from before birth to ovulation, the tech niques for its study and the patience required for detailed inquiry have been significant obstacles. At the same time, the suspicion that female meiotic analysis should not only be rewarding but that it may be mandatory has been with us ever since it was recognized that a positive correlation exists between chromosomal nondisjunction and maternal age. Before the intricacies of chromosomal behavior that are re sponsible for nondisjunction are understood, however, it is necessary that we comprehend the normalcy of the process.
