Book excerpt: Endothelial microvascular function of skin blood vessels is predictive of the cardiovascular disease risk (Holowatz et al., 2008). This study aims to examine differences in nitric oxide- (NO) dependent vasodilation during 39°C and 42°C local heating protocols and determine if the method of calculating NO contribution influences findings. We hypothesized that NO would contribute more to vasodilation when the skin blood flow (SkBF) values are subtracted (traditional) rather than the contribution value calculated from the percent change (relative). In addition, we hypothesized that older subjects would have reduced NO-dependent vasodilation in both protocols and with both methods of analysis. We conducted a cross-sectional study of 31 young (12 male/19 female, 24 (4) years) and 18 older (5 male/13 female, 68 (7.517)) participants. NO-dependent vasodilation was determined by perfusing (intradermal microdialysis) 15 nM N-nitro-l-arginine methyl ester during the heating plateau of the 39°C and 42°C protocols. Red blood cell flux (laser-Doppler flowmetry) was used to calculate cutaneous vascular conductance (CVC; red blood cell flux/mean arterial pressure), and values were represented as a percentage of maximum (%CVCmax) (28 nM sodium nitroprusside + 43°C). We found that when NO contribution is analyzed with the traditional method, NO contribution was lower in the older group than the young group in the 39°C heating protocol (p=0.030) but not in the 42°C protocol (p=0.262). We also found that NO contribution was lower in the 39°C protocol in the older group (p

This book was released on 2016-03-22 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the propagation of neural activity through synapses, to the integration of signals in the dendritic arbor, and the processes determining action potential generation, virtually all aspects of neural processing are plastic. This plasticity underlies the remarkable versatility and robustness of cortical circuits: it enables the brain to learn regularities in its sensory inputs, to remember the past, and to recover function after injury. While much of the research into learning and memory has focused on forms of Hebbian plasticity at excitatory synapses (LTD/LTP, STDP), several other plasticity mechanisms have been characterized experimentally, including the plasticity of inhibitory circuits (Kullmann, 2012), synaptic scaling (Turrigiano, 2011) and intrinsic plasticity (Zhang and Linden, 2003). However, our current understanding of the computational roles of these plasticity mechanisms remains rudimentary at best. While traditionally they are assumed to serve a homeostatic purpose, counterbalancing the destabilizing effects of Hebbian learning, recent work suggests that they can have a profound impact on circuit function (Savin 2010, Vogels 2011, Keck 2012). Hence, theoretical investigation into the functional implications of these mechanisms may shed new light on the computational principles at work in neural circuits. This Research Topic of Frontiers in Computational Neuroscience aims to bring together recent advances in theoretical modeling of different plasticity mechanisms and of their contributions to circuit function. Topics of interest include the computational roles of plasticity of inhibitory circuitry, metaplasticity, synaptic scaling, intrinsic plasticity, plasticity within the dendritic arbor and in particular studies on the interplay between homeostatic and Hebbian plasticity, and their joint contribution to network function.

Available in PDF, EPUB and Kindle. Book excerpt: Neural network research often builds on the fiction that neurons are simple linear threshold units, completely neglecting the highly dynamic and complex nature of synapses, dendrites, and voltage-dependent ionic currents. Biophysics of Computation: Information Processing in Single Neurons challenges this notion, using richly detailed experimental and theoretical findings from cellular biophysics to explain the repertoire of computational functions available to single neurons. The author shows how individual nerve cells can multiply, integrate, or delay synaptic inputs and how information can be encoded in the voltage across the membrane, in the intracellular calcium concentration, or in the timing of individual spikes. Key topics covered include the linear cable equation; cable theory as applied to passive dendritic trees and dendritic spines; chemical and electrical synapses and how to treat them from a computational point of view; nonlinear interactions of synaptic input in passive and active dendritic trees; the Hodgkin-Huxley model of action potential generation and propagation; phase space analysis; linking stochastic ionic channels to membrane-dependent currents; calcium and potassium currents and their role in information processing; the role of diffusion, buffering and binding of calcium, and other messenger systems in information processing and storage; short- and long-term models of synaptic plasticity; simplified models of single cells; stochastic aspects of neuronal firing; the nature of the neuronal code; and unconventional models of sub-cellular computation. Biophysics of Computation: Information Processing in Single Neurons serves as an ideal text for advanced undergraduate and graduate courses in cellular biophysics, computational neuroscience, and neural networks, and will appeal to students and professionals in neuroscience, electrical and computer engineering, and physics.

Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of nitric oxide as an endothelium-derived relaxing factor in 1987, investigations on its precise modes of action have been carried out at an extraordinary rate. Nitric oxide is now implicated in many physiological and pathological processes — not just in the control of vascular resistance, but in nerve transmission, cell proliferation, inflammatory responses and so on.Despite such rapid progress, no attempt has been made to combine the current knowledge of this subject matter in a single textbook. This volume has been written with the above in mind and presents a topical, comprehensive overview of the biochemistry and the physiological and pathophysiological effects of nitric oxide as they relate to the cardiovascular system. The therapeutic implications of nitric oxide are also considered. The text comprises contributions from many of the leading international authorities on the topic including Professor L J Ignarro, winner of the 1998 Nobel Prize in Physiology or Medicine.

Available in PDF, EPUB and Kindle. Book excerpt: Carrying on the high standards of the much-praised first edition of Nitric Oxide Protocols, Aviv Hassid has brought together a panel of expert researchers and clinician scientists to describe in step-by-step detail the latest methodologies for the measurement of nitric oxide--and the enzyme that produces it-in biological tissues and fluids. The authors take advantage of the latest methodologies for the quantitation of biological fluids and tissues, including capillary electrophoresis, microcoaxial electrodes, in vivo measurement of nitric oxide in exhaled air, confocal microscopy, gas chromatography, in situ hybridization, and real-time polymerase chain reaction. Chapters on the measurement of the novel products of nitric oxide, such as nitrated proteins, S-nitrosylated proteins, and dioxygen-dependent NO metabolism, are also included. Additional chapters address the expression of nitric oxide synthase via the use of viral vectors in gene therapy for erectile dysfunction and cancer, as well as in retrovirus, adenovirus, or adenoassociated virus-mediated expression of nitric oxide synthase in vivo. The protocols follow the successful Methods in Molecular BiologyTM series format, each one offering step-by-step laboratory instructions, an introduction outlining the principle behind the technique, lists of equipment and reagents, and tips on troubleshooting and avoiding known pitfalls. State-of-the-art and highly practical, Nitric Oxide Protocols, 2nd ed., offers investigators and clinican/scientists a gold-standard collection of readily reproducible analytical techniques for measuring levels of nitric oxide and determining its manifold functions and effects.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 87. This volume provides a review of progress made in recent years in experimental and theoretical investigation of the upper mesosphere and lower thermosphere and coupling between these regions and the ionosphere. Detailed study of the mesosphere/lower thermosphere/ionosphere (MLTI) region has historically been difficult because of its relative inaccessibility to direct measurement techniques and the complex and highly coupled processes which occur there. Although we have still not successfully unraveled all these complex interactions, we have made significant recent progress toward a fuller understanding of the basic state of the MLTI and of the dominant wave and coupling processes. This monograph includes a set of tutorial papers, which review our current understanding of aspects of the MLTI. These tutorials are interspersed with a selection of papers describing research progress on various topics of current interest in this region. The book should therefore be useful both to the newcomer, as an introduction to this field of research, and to the more experienced researcher, providing an overview of research in progress as well as a convenient reference collection of papers describing our current understanding.
