Recent developments have extended our knowledge of the basic functions of nerves: notably, the demonstration of the mechanism within nerve fibers which transports a wide range of essential materials. In order to understand how this discovery occurred, it is necessary to examine its history. The story begins in ancient Greece when nerves were conceived of as channels through which animal spirits carried sensory impressions to the brain. As science developed, the discoveries of various physical and chemical agents supplanted the agency of animal spirits until the molecular machinery of transport was recognized. In this fascinating and complete history, Sidney Ochs begins with a chronological look at this path of discovery, followed in the second half by a thematic approach wherein the author describes the electrical nature of the nerve impulse, fiber form and its changes in degeneration and regeneration, reflexes, learning, memory and other higher functions in which transport participates.

Recent years have witnessed striking advances in research on axons at a cellular level that substantially impact our current understanding of axonal biology. Newer findings and their ramifications are critically reviewed in the 16 chapters of this volume by authors highly qualified by virtue of their scientific contributions to research areas they know and write about. Five basic areas (I to V) germane to axonal biology are highlighted, beginning with (I) signaling interactions mediating myelination, and differentiation of axonal membrane domains; (IIa) issues surrounding organization and transport dynamics of neurofilaments in axons, (IIb) mechanisms regulating microtubule organization and dynamics, misregulation of which causes axonal degeneration, and (IIc) the roles actin binding proteins play in regulating organization and functions of the actin filament system in mature and growing axons; (IIIa) myosin motor proteins and cargoes intrinsic to the axon compartment, (IIIb) mitochondrial transport motors, and imperatives governing transport dynamics and directional delivery, (IIIc) mechanisms mediating retrograde signaling associated with NGF’s role in trophic-dependent neuronal survival, and (IIId) potential for impaired subcellular targeting of a -synuclein as a mechanism for accumulation of Lewy body inclusions in synucleinopathies; (IVa) occurrence and organization of discrete ribosome-containing domains in axons, (IVb) endogenous mRNAs, classes of proteins translated locally, and RNP trafficking in axons, (IVc) importance of locally synthesized nuclear encoded mitochondrial proteins for maintenance, function and survival of axons, (IVd) occurrence of RNA trafficking from glial cells to axons, and significance glial RNA transcripts may play in expression in axons and axon terminals, (IVe) RNA trafficking and localization of RNA transcripts in axonal growth cones, and signaling pathways that modulate local protein synthesis for directional elongation, and (IVf) genetic and molecular defects underlying spinal muscular atrophy, and roles that SMN gene product plays as a molecular chaperone in mRNA transport and translation; (Va) injury-induced local synthesis of a protein forming a retrograde signaling complex in axons to stimulate regeneration, and (Vb) endogenous and exogenous factors that condition axonal regenerative capacity in PNS and CNS, including injury-induced activation of specific genes governing regeneration. Emergent complexities revealed in this volume compel a major revision in the traditional conceptual model of the axon’s intrinsic makeup and capacities.

This entertaining and informative book describes how living things bump up against non-biological reality. "My immodest aim," says the author, "is to change how you view your immediate surroundings." He asks us to wonder about the design of plants and animals around us: why a fish swims more rapidly than a duck can paddle, why healthy trees more commonly uproot than break, how a shark manages with such a flimsy skeleton, or how a mouse can easily survive a fall onto any surface from any height. The book will not only fascinate the general reader but will also serve as an introductory survey of biomechanics. On one hand, organisms cannot alter the earth's gravity, the properties of water, the compressibility of air, or the behavior of diffusing molecules. On the other, such physical factors form both constraints with which the evolutionary process must contend and opportunities upon which it might capitalize. Life's Devices includes examples from every major group of animals and plants, with references to recent work, with illustrative problems, and with suggestions of experiments that need only common household materials.

Without a cytoskeleton, a neuron or glial cell would be a shapeless jelly mass unable to function in the milieu of the brain. If we are to understand neuronal cells function in health and disease, we must determine how the cytoskeleton forms and contributes to neural physiology and pathobiology. Cytoskeleton of the Nervous System provides a comprehensive, authoritative and up-to-date account of what we now know and what we want to know in the near future--about the functioning of the cytoskeleton of neuronal cells at the molecular level. In lively accounts, which are unafraid to address controversy, Cytoskeleton of the Nervous System introduces readers to the most sophisticated concepts and latest discoveries: from overexpression systems to knock-out models for specific cytoskeletal proteins, from continuous transport assays in vivo to live-cell imaging in primary neurons, and from factors regulating cytoskeleton behavior to the dysregulation of these processes leading to neurological disease.

This collection of review articles authored by international experts pulls together current information about the role of mitochondria in aging and diseases of aging. Mitochondria are vitally important cellular organelles and undergo their own aging process becoming less efficient in aged animals including humans. These changes have wide-ranging significance contributing to immune dysfunction (autoimmunity and immune deficiency), inflammation, delayed healing, skin and retinal damage, cancer and most of the degenerative diseases of aging. Mitochondrial aging predisposes to drug toxicity in the geriatric population and to many of the features of normal aging. The research detailed in this book summarizes current understanding of the role of mitochondria in the complex molecular changes of aging, moving on to specific diseases of aging. Mitochondrial dysfunction is an important target for development of treatments for aging and disease. The last article details how exercise is a treatment and combats many features of the aging process.
