This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.
This is the only book to date offering a critical overview of Shinto from early times to the modern era, and evaluating Shinto's place in Japanese religious culture. In recent years, a few books on medieval Shinto have appeared, but none has attempted to depict the broader picture, to examine critically Shinto's origins and its subsequent development through the medieval, pre-modern and modern periods. The essays in this book address such key topics as Shinto and Daoism in early Japan, Shinto and the natural environment, Shinto and state ritual in early Japan, Shinto and Buddhism in medieval Japan, and Shinto and the state in the modern period. All of the essays highlight the dynamic nature of Shinto and shrine history by focusing on the three-way relationship, often fraught, between local shrine cults, Shinto agendas and Buddhism.
Cell fusions are important to fertilization, placentation, development of skeletal muscle and bone, calcium homeostasis and the immune defence system. Additionally, cell fusions participate in tissue repair and may be important to cancer development, progression and therapy. A large number of factors regulate cell fusions, including receptors and ligands, membrane domain organizing proteins, proteases, signaling molecules and fusogenic proteins that bring membranes close together. In the present volume, we interrogate what mechanisms that may be important to cell fusions in mammals and what mechanisms that may be shared with lower organisms and viruses. Additionally, the importance of cell fusions to the pathogenesis as well as treatment of diseases is addressed.
In this book a team of leading experts provide a collection of overviews that outline our current understanding of cell fusion. They further provide methods that present classic and state-of-the-art experimental approaches in a variety of systems.
Abstract : Background : Vesicle‐associated membrane protein 5 (VAMP5) is a member of the SNARE protein family, which regulates the docking and fusion of membrane vesicles within cells. Previously, we reported ubiquitous expression of VAMP5 proteins in various organs except the brain and small intestine. However, the precise roles of VAMP5 in each organ remain unclear. To explore the roles of VAMP5 in vivo, we generated VAMP5 knockout (KO) mice.Results : VAMP5 KO mice showed low birth rate and low body weight. KO embryos grew normally in the uterus, and tended to die around birth. Anatomical analysis revealed that viable KO mice often exhibited duplication of the ureter, and dead KO mice sh...
Distinguished scholar of Japanese religions and culture Helen Hardacre offers the first comprehensive history of Shinto, the ancient and vibrant tradition whose colorful rituals are still practiced today. Under the ideal of Shinto, a divinely descended emperor governs through rituals offered to deities called Kami. These rituals are practiced in innumerable shrines across the realm, so that local rites mirror the monarch's ceremonies. Through this theatre of state, it is thought, the human, natural, and supernatural worlds will align in harmony and prosper. Often called "the indigenous religion of Japan," Shinto's institutions, rituals, and symbols are omnipresent throughout the island natio...
Molecular Biology of RNA: New Perspectives provides an overview of the developments in RNA research as well as the approaches, strategies, and methodologies used. Most of the contributing authors in the present volume participated in the Fifth Stony Brook Symposium entitled "New Perspectives on the Molecular Biology of RNA" in May 1986. The text is organized into six parts. Part I contains papers dealing with RNA as an enzyme. Part II presents studies on RNA splicing. Part III examines RNA viruses while Part IV focuses on the role of RNA in DNA replication. Part V is devoted to the structure, function, and isolation of RNA. Finally, Part VI takes up the role of RNA in regulation and repression. This volume will help provide new direction and insight for those already working on the subject and will serve as a useful guide to those about to start research in the molecular biology of RNA.
