This book was released on 1990-02-01 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reevaluates the health risks of ionizing radiation in light of data that have become available since the 1980 report on this subject was published. The data include new, much more reliable dose estimates for the A-bomb survivors, the results of an additional 14 years of follow-up of the survivors for cancer mortality, recent results of follow-up studies of persons irradiated for medical purposes, and results of relevant experiments with laboratory animals and cultured cells. It analyzes the data in terms of risk estimates for specific organs in relation to dose and time after exposure, and compares radiation effects between Japanese and Western populations.
Download or read book Understanding the Impact of Gene mutation on Health Diseases An Overview written by Dr.HAKIM and published by Dr.Hakim Saboowala. This book was released on 2020-04-09 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Each cell depends on thousands of proteins to do their jobs in the right places at the right times, to function correctly Sometimes, gene mutations prevent one or more of these proteins from working properly. By changing a gene’s instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth. · These changes occur in genes that are essential for development, and often disrupt the development of an embryo in its earliest stages. · Because these mutations have very serious effects, they are incompatible with life. It is important to note that genes themselves do not cause disease—genetic disorders are caused by mutations that make a gene function improperly. · For example, when people say that someone has the “cystic fibrosis gene,” they are usually referring to a mutated version of the CFTR gene, which causes the disease. · All people, including those without cystic fibrosis, have a version of the CFTR gene An attempt has been made in this informative Booklet to summarize the fundamental topics related to genetic mutations and its impact on health and development along with several illustrations. …Dr. H.

Download or read book Gene Mutations written by Helena M. Christoffersen and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gene is a DNA sequence that can be transcribed into an RNA molecule and transferred to offspring organisms. Changes in DNA sequences that determine the structure and function of a gene are called mutations. Gene Mutations: Causes and Effects opens by exploring the physical, chemical, and biological agents that cause mutations interact with DNA, leading to genetic instability. Recent advances in next-generation sequencing have led to the discovery of new causative genes or those mutations. The authors describe the phenotypes and gene mutations, discussing genotype-phenotype correlations compared with previous reports. Lastly, one study analyses all conflicting data concerning the amplification of the ESR1 gene, particularly its ambiguous prevalence in both untreated tumors and tumors either responsive or unresponsive to antiestrogen therapy.
Download or read book The Gene written by Siddhartha Mukherjee and published by Simon and Schuster. This book was released on 2016-05-17 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: The #1 NEW YORK TIMES Bestseller The basis for the PBS Ken Burns Documentary The Gene: An Intimate History Now includes an excerpt from Siddhartha Mukherjee’s new book Song of the Cell! From the Pulitzer Prize–winning author of The Emperor of All Maladies—a fascinating history of the gene and “a magisterial account of how human minds have laboriously, ingeniously picked apart what makes us tick” (Elle). “Sid Mukherjee has the uncanny ability to bring together science, history, and the future in a way that is understandable and riveting, guiding us through both time and the mystery of life itself.” —Ken Burns “Dr. Siddhartha Mukherjee dazzled readers with his Pulitzer Prize-winning The Emperor of All Maladies in 2010. That achievement was evidently just a warm-up for his virtuoso performance in The Gene: An Intimate History, in which he braids science, history, and memoir into an epic with all the range and biblical thunder of Paradise Lost” (The New York Times). In this biography Mukherjee brings to life the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices. “Mukherjee expresses abstract intellectual ideas through emotional stories…[and] swaddles his medical rigor with rhapsodic tenderness, surprising vulnerability, and occasional flashes of pure poetry” (The Washington Post). Throughout, the story of Mukherjee’s own family—with its tragic and bewildering history of mental illness—reminds us of the questions that hang over our ability to translate the science of genetics from the laboratory to the real world. In riveting and dramatic prose, he describes the centuries of research and experimentation—from Aristotle and Pythagoras to Mendel and Darwin, from Boveri and Morgan to Crick, Watson and Franklin, all the way through the revolutionary twenty-first century innovators who mapped the human genome. “A fascinating and often sobering history of how humans came to understand the roles of genes in making us who we are—and what our manipulation of those genes might mean for our future” (Milwaukee Journal-Sentinel), The Gene is the revelatory and magisterial history of a scientific idea coming to life, the most crucial science of our time, intimately explained by a master. “The Gene is a book we all should read” (USA TODAY).

Download or read book Genes Behavior and the Social Environment written by Institute of Medicine and published by National Academies Press. This book was released on 2006-12-07 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

Download or read book Mobilizing Mutations written by Daniel Navon and published by University of Chicago Press. This book was released on 2019-09-20 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: With every passing year, more and more people learn that they or their young or unborn child carries a genetic mutation. But what does this mean for the way we understand a person? Today, genetic mutations are being used to diagnose novel conditions like the XYY, Fragile X, NGLY1 mutation, and 22q11.2 Deletion syndromes, carving out rich new categories of human disease and difference. Daniel Navon calls this form of categorization “genomic designation,” and in Mobilizing Mutations he shows how mutations, and the social factors that surround them, are reshaping human classification. Drawing on a wealth of fieldwork and historical material, Navon presents a sociological account of the ways genetic mutations have been mobilized and transformed in the sixty years since it became possible to see abnormal human genomes, providing a new vista onto the myriad ways contemporary genetic testing can transform people’s lives. Taking us inside these shifting worlds of research and advocacy over the last half century, Navon reveals the ways in which knowledge about genetic mutations can redefine what it means to be ill, different, and ultimately, human.
Download or read book Evolution by Gene Duplication written by Susumu Ohno and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is said that "necessity is the mother of invention". To be sure, wheels and pulleys were invented out of necessity by the tenacious minds of upright citi zens. Looking at the history of mankind, however, one has to add that "Ieisure is the mother of cultural improvement". Man's creative genius flourished only when his mind, freed from the worry of daily toils, was permitted to entertain apparently useless thoughts. In the same manner, one might say with regard to evolution that "natural selection mere(y tnodifted, while redundanry created". Natural selection has been extremely effective in policing alleHe mutations which arise in already existing gene loci. Because of natural selection, organisms have been able to adapt to changing environments, and by adaptive radiation many new species were created from a common ancestral form. Y et, being an effective policeman, natural selection is extremely conservative by nature. Had evolution been entirely dependent upon natural selection, from a bacterium only numerous forms of bacteria would have emerged. The creation of metazoans, vertebrates and finally mammals from unicellular organisms would have been quite impos sible, for such big leaps in evolution required the creation of new gene loci with previously nonexistent functions. Only the cistron which became redun dant was able to escape from the relentless pressure of natural selection, and by escaping, it accumulated formerly forbidden mutations to emerge as a new gene locus.

Download or read book Mutation written by Robin Cook and published by Penguin. This book was released on 1990-02-01 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this masterpiece of techno-medical suspense from the “master of the medical thriller” (The New York Times), Robin Cook tells the explosive tale of a brilliant doctor who sought to create the son of his dreams—and invented a living nightmare... When OB/GYN and biomolecular researcher Dr. Victor Frank learns of his wife’s infertility, he initiates a bold—and dangerous—experiment. Unbeknownst to everyone, including her, Dr. Frank has adapted the methods of animal husbandry and molecular genetics to human reproduction. Fusing his wife’s eggs and his own sperm, he sets in motion the production of a superior being, his child. The result of this experiment, a son, VJ, is born to a surrogate mother and legally adopted by the Franks. To their delight, their son is physically perfect, and by the age of three, displays the complex problem-solving abilities of a prodigy. Then, without warning, VJ’s intelligence level plunges to a point appropriate to his age, but stabilizes. For the moment, Dr. Frank can breathe a sigh of relief: even if VJ is no longer the genius he was, at least he will be normal. But that relief is tragically short-lived, for all too soon VJ begins to change again. And this time, there is no cause for comfort—only terror.
