Book Synopsis Dynamics of the Mammalian Sperm Head by : Kiyotaka Toshimori
Download or read book Dynamics of the Mammalian Sperm Head written by Kiyotaka Toshimori and published by Springer Science & Business Media. This book was released on 2009-04-28 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mammalian spermatozoa have complex structures. The structure-function relationship of sperm has been studied from various viewpoints. Accumulated evidence has shown that the sperm components undergo sequential changes from the beginning of spermatogenesis to the time of fertilization/embryogenesis. Structural analyses have been performed using various new techniques of light and electron microscopy as well as immunohistochemistry and immunocytochemistry in combination with specific probes such as antibodies against sperm components. Recently developed gene-manipulation techniques have accelerated investigations on the events that govern the relationship between the structure and molecular components of sperm. In addition, animal models with gene manipulations have been shown to exhibit various morphological and functional abnormalities that lead to infertility. In this book, I discuss the events that occur in the normal sperm head and govern the structure-function relationship from the time of spermatogenesis to that of fertilization or egg activation. In this regard, I describe dynamic modifications and maturation events occurring in sperm-head components and compare the outcomes of these events with the outcomes of their failure.
Book Synopsis Sperm Acrosome Biogenesis and Function During Fertilization by : Mariano G. Buffone
Download or read book Sperm Acrosome Biogenesis and Function During Fertilization written by Mariano G. Buffone and published by Springer. This book was released on 2016-05-19 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, acrosomal exocytosis (also called the “acrosome reaction”) has been recognized as playing an essential role in fertilization. Secretion of this granule is an absolute requirement for physiological fertilization. In recent years, the study of mammalian acrosomal exocytosis has yielded some major advances that challenge the long-held, general paradigms in the field. Principally, the idea that sperm must be acrosome-intact to bind to the zona pellucida of unfertilized eggs, based largely on in vitro fertilization studies of mouse oocytes denuded of the cumulus oophorus, has been overturned by experiments using state-of-the-art imaging of cumulus-intact oocytes and fertilization experiments where eggs were reinseminated by acrosome-reacted sperm recovered from the perivitelline space of zygotes. From a molecular point of view, acrosome exocytosis is a synchronized and tightly regulated process mediated by molecular mechanisms that are homologous to those reported in neuroendocrinal cell secretions. The authors provide a broader perspective, focusing on a limited number of important topics that are essential for understanding the molecular mechanisms governing this step in the fertilization process. They also discuss molecular aspects such as the signaling pathways leading to exocytosis, including the participation of ion channels, lipids, the fusion machinery proteins and the actin cytoskeleton as well as cellular aspects such as the site of acrosomal exocytosis and the use of gene-manipulated animals to study this process.

Book Synopsis The Evolution of Anisogamy by : Tatsuya Togashi
Download or read book The Evolution of Anisogamy written by Tatsuya Togashi and published by Cambridge University Press. This book was released on 2011-04-14 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin identified the existence of separate male and female gametes as one of the central mysteries of evolutionary biology. 150 years later, the question of why male gametes exist remains an intriguing puzzle. In this, the first book solely devoted to the evolution of anisogamy, top theorists in the field explore why gamete dimorphism characterizes nearly all plants and animals. Did separate male and female gametes evolve as a result of competition, or does anisogamy instead represent selection for cooperation? If disruptive selection drove the evolution of anisogamy, with male gametes focused on search and fusion, and female gametes provisioning the new zygote, why do some algal species continue to produce gametes of a single size? Does sperm limitation, or escape from infection, better explain the need for extremely small, highly mobile sperm? Written by leaders in the field, this volume offers an authoritative and cutting-edge overview of evolutionary theory.

Book excerpt: Did you know that Kellogg's cornflakes were supposed to cure masturbation? Why was the Catholic church so insistent that sex could only be performed in the missionary position? In this book, you will find out why to testify meant to grab someone else's testicles, and why young boys in Papua New Guinea thought they had to drink older men's semen to attain puberty. St. Augustine believed that semen was a fluid that transmits Adam's original sin to every unborn child, Chinese and Indian scholars thought that it gives a person vitality. This book will tell you the ancient secret of achieving multiple male orgasms, and give you the recipe for semen infused French crepes. It covers 5000 years of semen history from an ancient Egyptian god performing auto-fellatio, to today's over one million Americans suddenly discovering that their biological father was an anonymous college student earning $10 a pop at the local sperm bank. Called everything from a magic elixir, the giver of life, to the essence of sin, this is its story
Book Synopsis Concepts of Biology by : Samantha Fowler
Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
