Book Description
The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement, behavior, and coordinated thinking. Invertebrate neurobiology has traditionally been studied in specific model organisms, whilst knowledge of the broad diversity of nervous system architecture and its evolution among metazoan animals has received less attention. This is the first major reference work in the field for 50 years, bringing together many leading evolutionary neurobiologists to review the most recent research on the structure of invertebrate nervous systems and provide a comprehensive and authoritative overview for a new generation of researchers. Presented in full colour throughout, Structure and Evolution of Invertebrate Nervous Systems synthesizes and illustrates the numerous new findings that have been made possible with light and electron microscopy. These include the recent introduction of new molecular and optical techniques such as immunohistochemical staining of neuron-specific antigens and fluorescence in-situ-hybridization, combined with visualization by confocal laser scanning microscopy. New approaches to analysing the structure of the nervous system are also included such as micro-computational tomography, cryo-soft X-ray tomography, and various 3-D visualization techniques. The book follows a systematic and phylogenetic structure, covering a broad range of taxa, interspersed with chapters focusing on selected topics in nervous system functioning which are presented as research highlights and perspectives. This comprehensive reference work will be an essential companion for graduate students and researchers alike in the fields of metazoan neurobiology, morphology, zoology, phylogeny and evolution.

Book Description
This volume examines cells set aside during development for use later in ontogeny or in adult life. There is no single term for such cells. The cells explored fall within several major categories — stem cells, set-aside cells (in echinoderm larvae), imaginal discs in insects such as Drosophila, meristems (plants), blastemata (regeneration in amphibians), neoblasts (regeneration in planarians). The book compares and contrasts these cell types and the environments (niches) in which they operate with the aim of unravelling any relationships between them, between their activation in development, and in their evolution. Key Features Explores the nature of deferred-use cells in evolutionary and developmental context. Reviews the mechanisms of development of set-aside cells, such as stem cells, meristems, and imaginal discs. Provides phylogenetic overview of different types of deferred-use cells. Compares and contrasts different theories on the origin of deferred-use cells. Related Titles Calegari, F. & C. Waskow, eds.

Book Description
The final volume of this new innovative and informative three-volume set explains and explores the essential basic and advanced concepts from various areas within the nanosciences. This volume primarily focuses on increasing awareness of sustainable nanochemistry, meaning the social and economic impact of nanochemistry, in order to mitigate ecological resource depletion and to promote the exploration of nature as a resource for future benefits. This volume adopts a pharmacological lens, examining the multitude of ways in which nano-research can contribute to the development of pharmaceutical drugs and paying particular attention to toxicology and renewable energy within nanochemistry. Under the vast expertise of the editor, the volume contains 34 entries contributed by renowned international scientists and scholars. The content in this volume covers topics such as anti-HIV agents, ecotoxicology, solar cells and photovoltaic phenomena, spectral-SAR, and more—alphabetically organized and accompanied by equations, figures, and brief letters in order to emphasize the potential applications of the concepts discussed.

Book Description
Building the Most Complex Structure on Earth provides readers with a basic biological education an easy and understandable introduction into a new epigenetic theory of development and evolution. This is a novel theory that describes the epigenetic mechanisms of the development and evolution of animals and explains the colossal evolution and diversification of animals from a new post-genetic perspective. Modern biology has demonstrated the existence of a common genetic toolkit in the animal kingdom, but neither the number of genes nor the evolution of new genes is responsible for the development and evolution of animals. The failure to understand how the same genetic toolkit is used to produce millions of widely different animal forms remains a perplexing conundrum in modern biology. The novel theory shows that the development and evolution of the animal kingdom are functions of epigenetic mechanisms, which are the competent users of the genetic toolkit. - Provides a comprehensive view of the epigenetic aspects of reproduction, development, and evolution. - Highly rigorous, but simple enough for readers with only a basic knowledge of biology.

Book Description
Handbook of Hormones: Comparative Endocrinology for Basic and Clinical Research, Second Edition presents a catalog of fundamental information on the structure and function of hormones from basic biology to clinical use, offering a rapid way to obtain specific facts about the chemical and molecular characteristics of hormones, their receptors, signaling pathways, and the biological activities they regulate. The book's stellar editorial board, affiliated with the Japan Society for Comparative Endocrinology, brings together authors that present a compelling structure of each hormone with a consistent presentation that provides a primer surrounding the plethora of hormones that now exist. Comparative endocrinology continues to rapidly expand and new information about hormones is being produced almost daily, making it important to stay up-to-date. Hormone, paracrine, and autocrine factors have been identified as key players in a range of different systems, including immune, musculoskeletal and cardiovascular. Frontiers between disciplines are being blurred and many scientists in fields other than endocrinology are interested in hormones. Scientists now have the unprecedented opportunity to look from invertebrates to vertebrate and identify novel regulatory factors and understand their function and how they determine an organism’s physiology and survival. Presents hormones in groups according to their origin so that readers can easily understand their inter-relation Includes 47 new hormones, such as neuropeptides, cytokines, growth hormones, biogenic amines and amino acids that are important for cell to cell communication via endocrine, paracrine and neurotransmitter signaling Summarizes the current knowledge of hormone evolution based on comparative genome resources, such as synteny, genome sequence and comprehensive phylogeny Covers a wide range of information on hormones, from basic information on structure and function across vertebrate and invertebrate phyla to clinical applications Collates key information on 259 hormones and 47 groups/families

Book Description
Animal behaviors and emotions are fine-tuned via signal transmission and communication between cells. The nervous system gives instructions and transmits signals to different parts of an organism to produce coordinated activities. Neurons are core components of the nervous system and they use various chemical messengers to communicate with one another. Neuropeptides (NPs), which are small chains of amino acids, represent the largest class of signaling molecules. Since NPs are directly involved in modulating many physiological processes, such as metabolism, reproduction, learning, memory, and social behaviors–there is a growing interest in studying their structures, functions, and distributions. This book aims to summarize advances in invertebrate NP studies concerning molecular diversities, distributions, and biological functions. In addition, the emerging mass spectrometric techniques have been discussed extensively as a powerful tool enabling accelerated invertebrate NP studies.
