Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book Inner Ear Hair Cell Loss and Stereocilia Defects in MiR 183 Family Knockout Models written by Marsha Louise Pierce and published by . This book was released on 2015 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hearing loss is the most prevalent sensory defect, and although hearing aids and cochlear implants can provide sensory input, no current therapeutic options exist for restoration of normal hearing. The microRNA-183 family (miR-183, miR-96, and miR-182) is highly conserved and coordinately expressed in neurosensory cells including hair cells (HCs) and sensory neurons in the inner ear, and mutations in miR-96 cause deafness in both mice and humans. To specifically investigate the effects of miR-183 family member loss-of-function, miR-183/96 and miR-182 knockout (KO) mice were assessed. Behavioral observations and evaluation of Preyer's reflex were used to grossly assess hair cell function. Stereocilia defects and hair cell loss in mice ranging from birth (postnatal day zero; P0) to P180 were examined by immunofluorescence microscopy (IFM) detection of MyoVIIa, scanning electron microscopy (SEM), and phase contrast microscopy (PCM) of plastic embedded sections through the organ of Corti. Spiral ganglion innervation was evaluated by IFM detection for acetylated tubulin. Targetscan predicted target genes were compared to neonatal and adult hair cell transcriptomes, genes known to cause hereditary hearing loss, and miR-183 familly confirmed target genes in the literature to identify a relevant subset of genes for further evaluation. Here we show that miR-183/96 KO caused delayed stereocilia development, gross stereocilia disorganization, hair cell loss, innervation defects and deafness. Moreover, miR-183/96 heterozygous (HET) and miR-182 KO mice showed relatively subtle stereocilia defects and age-related loss of acoustic startle response. Arhgdia, Sox2 and Tes were co-expressed with miR-183 family members and mildly upregulated in miR-183/96 KO mice, suggesting such targets might play a role in the observed phenotype. Results demonstrate that miR-183 family loss-of-function (LOF) led to stereocilia defects, hair cell loss, and contributing to hearing deficits. The challenge remains to conclusively identify miR-183 family effects on target genes and pathways that support hair cell maintenance and function to provide insight to approaches for preventing hair cell loss.

Download or read book Noise and the Brain written by Jos J. Eggermont and published by Academic Press. This book was released on 2013-09-12 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: In our industrialized world, we are surrounded by occupational, recreational, and environmental noise. Very loud noise damages the inner-ear receptors and results in hearing loss, subsequent problems with communication in the presence of background noise, and, potentially, social isolation. There is much less public knowledge about the noise exposure that produces only temporary hearing loss but that in the long term results in hearing problems due to the damage of high-threshold auditory nerve fibers. Early exposures of this kind, such as in neonatal intensive care units, manifest themselves at a later age, sometimes as hearing loss but more often as an auditory processing disorder. There is even less awareness about changes in the auditory brain caused by repetitive daily exposure to the same type of low-level occupational or musical sound. This low-level, but continuous, environmental noise exposure is well known to affect speech understanding, produce non-auditory problems ranging from annoyance and depression to hypertension, and to cause cognitive difficulties. Additionally, internal noise, such as tinnitus, has effects on the brain similar to low-level external noise.Noise and the Brain discusses and provides a synthesis of hte underlying brain mechanisms as well as potential ways to prvent or alleviate these aberrant brain changes caused by noise exposure. - Authored by one of the preeminent leaders in the field of hearing research - Emphasizes direct and indirect changes in brain function as a result of noise exposure - Provides a comprehensive and evidence-based approach - Addresses both developmental and adult plasticity - Includes coverage of epidemiology, etiology, and genetics of hearing problems; effects of non-damaging sound on both the developing and adult brain; non-auditory effects of noise; noise and the aging brain; and more

Download or read book Cell and Molecular Biology of the Ear written by David J. Lim and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dr. Howard House, founder of the House Ear Institute and House Ear Clinic often uses the analogy of planting a seed when referring to establishing the House Ear Institute in 1946. Two grateful patients of Dr. House put forth the idea that his knowledge and innovative skills could be used to expand the understanding of hearing impairment and its treatment. Those two early patients provided the "seed money" to begin the Institute. Since that time, the growth has been phenomenal from a one-man laboratory to a multidisciplinary facility boasting over 175 scien tists, physicians, and support staff, all dedicated to the advancement of otologic research and education. Six years ago after a half-century of remarkable success with prosthetic and device research, the Institute began cultivating a new field of endeavor-cell and molecular biology. Don Nielsen, then the Institute's Executive Vice President for Research and Scientific Director, began exploring the potential for hair cell regen eration and presented his ideas to the Board of Trustees. For a period of six months, we did a lot of fact finding to assess what role the Institute might take in this excit ing new field.

Download or read book Regenerative Medicine for the Inner Ear written by Juichi Ito and published by Springer. This book was released on 2014-08-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research described in this book represents important steps toward understanding the development of inner ear medicine and new perspectives in regenerative medicine, including efficacy in cochlear implants and various other treatments. The book depicts the mechanisms that underlie inner ear diseases, their experimental models, and proposals for new strategies to treat their symptoms. As well, the exciting future prospects for dealing with the very common problem of inner ear diseases are explained. These disorders occur among many people and include sensorineural hearing loss (SNHL), sudden deafness, senile deafness, noise-induced deafness, tinnitus, dizziness–vertigo, and Ménière’s disease. In Japan alone, there are more than 6 million deaf patients including those with middle-range deafness. There is currently no effective treatment, and regardless of the underlying cause, the damage has been considered irreversible. However, the results of recent research show that these patients actually can recover. The study of hair cells, spiral ganglion neurons, and stem cells for inner ear diseases such as SNHL, tinnitus, dizziness, and vertigo is at the forefront of regenerative medicine and may provide solutions to some of these problems. The information presented here makes this book a valuable professional reference work for all doctors and researchers in the field of otolaryngology who focus on regenerative treatments for inner ear diseases.

Download or read book Development of the Inner Ear written by Matthew Kelley and published by Springer Science & Business Media. This book was released on 2005-10-20 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the embryonic development of the vertebrate inner ear in six chapters that span all aspects of inner ear development, from the induction of the otic placode through cellular morphogenesis, to the onset of auditory function. In each chapter, a particular aspect of development of the inner ear is examined in terms of both classic embryologic experiments and more recent advances using molecular biological techniques. The publication of this volume is particularly timely in light of recent significant advances in molecular biological and cellular imaging techniques. These changes have led to an explosion in the pace of developmental inner ear research that is clearly reflected in the chapters presented here. The book will serve as a useful resource for scientists who study inner ear biology, as well as developmental biologists who work in other systems, but have an interest in an overview of the developing ear. This book will also be a valuable resource for clinicians who wish to know more about the development of the ear and about the genetic and molecular factors that regulate its formation. Matthew Kelley and Doris Wu are both Investigators at the National Institute on Deafness and other Communication Disorders at the National Institutes of Health, Bethesda, Maryland. Arthur N. Popper is Professor in the Department of Biology and Co-Director of the Center for Comparative and Evolutionary Biology of Hearing at the University of Maryland, College Park. Richard R.

Available in PDF, EPUB and Kindle. Book excerpt: Development of Auditory and Vestibular Systems fourth edition presents a global and synthetic view of the main aspects of the development of the stato-acoustic system. Unique to this volume is the joint discussion of two sensory systems that, although close at the embryological stage, present divergences during development and later reveal conspicuous functional differences at the adult stage. This work covers the development of auditory receptors up to the central auditory system from several animal models, including humans. Coverage of the vestibular system, spanning amphibians to effects of altered gravity during development in different species, offers examples of the diversity and complexity of life at all levels, from genes through anatomical form and function to, ultimately, behavior. The new edition of Development of Auditory and Vestibular Systems will continue to be an indispensable resource for beginning scientists in this area and experienced researchers alike. - Full-color figures illustrate the development of the stato-acoustic system pathway - Covers a broad range of species, from drosophila to humans, demonstrating the diversity of morphological development despite similarities in molecular processes involved at the cellular level - Discusses a variety of approaches, from genetic-molecular biology to psychophysics, enabling the investigation of ontogenesis and functional development
