Flagellar Mechanics and Sperm Guidance


Book Description

Experimental research using spermatozoa, a highly specialized cell with organelles involved in gene transfer, energy supply and cellular motility, has always occupied the forefront of studies in cell and reproductive biology. Several spermatological experiments have focused on the attraction of a spermatozoon toward the egg – sperm chemotaxis or sperm guidance. This process ubiquitously occurs in the reproductive system of many organisms. After its discovery in the late 19th century in plants, sperm chemotaxis is known to play a crucial role in fertilization success in both plants and animals. Spermatology has expanded in focus in recent years, as the structure of molecules relevant to sperm chemotaxis has been recently determined in several species of invertebrates and vertebrates, which promises remarkable progress for understanding events relevant to sexual reproduction. Reflecting upon these trends in the long history of sperm chemotaxis, Flagellar Mechanics and Sperm Guidance gathers leaders in the field of spermatology, who have presented their experimental research on the chemical cues behind flagellate behavior in a variety of organisms including bikonts and spermatozoa of marine invertebrates and vertebrates (fish, amphibians and mammals). Reviews presented in this monograph provide both basic and detailed information on the initiation and activation of sperm motility at spawning, sperm thermotaxis, and other mechanics such as mathematical models of a spermatozoon swimming. A comparison between features of sperm chemotaxis among different organisms is also given. Flagellar Mechanics and Sperm Guidance will stir interest in spermatology research among a broad variety of readers including researchers, Ph.D. students studying reproductive biology and teachers involved in advanced biology courses.

Handbook of Dynein (Second Edition)


Book Description

Dyneins are molecular motors that are involved in various cellular processes, such as cilia and flagella motility, vesicular transport, and mitosis. Since the first edition of this book was published in 2012, there has been a significant breakthrough: the crystal structures of the motor domains of cytoplasmic dynein have been solved and the previously unknown details of this huge and complex molecule have been unveiled. This new edition contains 14 chapters written by researchers in the US, Europe, and Asia, including 3 new chapters that incorporate new fields. The other chapters have also been substantially updated. Compared with the earlier edition, this book focuses more on the motile mechanisms of dynein, especially by biophysical methods such as cryo-EM, X-ray crystallography, and single-molecule nanometry. It is a major handbook for frontline researchers as well as for advanced students studying cell biology, molecular biology, biochemistry, biophysics, and structural biology.




Cytoskeleton


Book Description

The cytoskeleton is a highly dynamic intracellular platform constituted by a three-dimensional network of proteins responsible for key cellular roles as structure and shape, cell growth and development, and offering to the cell with "motility" that being the ability of the entire cell to move and for material to be moved within the cell in a regulated fashion (vesicle trafficking). The present edition of Cytoskeleton provides new insights into the structure-functional features, dynamics, and cytoskeleton's relationship to diseases. The authors' contribution in this book will be of substantial importance to a wide audience such as clinicians, researches, educators, and students interested in getting updated knowledge about molecular basis of cytoskeleton, such as regulation of cell vital processes by actin-binding proteins as cell morphogenesis, motility, their implications in cell signaling, as well as strategies for clinical trial and alternative therapies based in multitargeting molecules to tackle diseases, that is, cancer.




Reproduction in Aquatic Animals


Book Description

This book provides an up-to-date overview of the various reproductive systems of a variety of aquatic animals, from invertebrates to fishes. While all terrestrial animals use internal fertilization, aquatic animals have diverse reproductive systems. Some are internal fertilizers with or without mating, but many perform external fertilization. Because of this diversity, the reproductive systems of aquatic animals represent excellent models for the study of adaptive evolution and the species specificity of fertilization. In addition, many aquatic animals, including fish, crustaceans, and mollusks, are important as fishery and aquaculture resources. In this book, up-and-coming researchers examine reproductive systems in representative aquatic animals, covering both the basic knowledge and late-breaking results. Reproduction in Aquatic Animals: From Basic Biology to Aquaculture Technology will be of interest to graduate and postgraduate students in biology and agricultural sciences, as well as to researchers and technicians in the fields of reproductive biology and fishery science and to non-academics.




Cryopreservation of Fish Gametes


Book Description

Understanding the reproductive physiology and endocrinology of fishes is essential for captive maturation and seed production in the field of aquaculture. Studying the spermatology of fishes is a comparatively new focus in aquaculture, which has emerged as an important area of fish research over the past two decades. In this regard, the cryopreservation of fish gametes is a crucial aspect. Moreover, energetics studies of gametes have become essential, considering the loss of vigour in the spermatozoa after cryopreservation.The latest development in this context is the cryopreservation of spermatogonial stem cell, which is also covered in the book, along with detailed information on embryo cryopreservation in fishes and crustaceans. The role of cryopreservation in conservation programmes is another important aspect, one that will especially interest biologists.This book addresses central issues in fish gamete cryopreservation and breeding, while also reviewing the history of cryopreservation. Its most unique feature is the breadth of its coverage, from basic information on reproduction in fishes, to such advanced topics as embryo cryopreservation. Chiefly intended as a handy troubleshooting guide, the book represents a valuable resource for research students in related fields.

Female Control


Book Description

Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most postcopulatory competition among males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests, Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans.
