Download or read book Epigenetics of Aging written by Trygve O. Tollefsbol and published by Springer Science & Business Media. This book was released on 2009-11-11 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.
Download or read book Heredity under the Microscope written by Soraya de Chadarevian and published by University of Chicago Press. This book was released on 2020-07-02 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: By focusing on chromosomes, Heredity under the Microscope offers a new history of postwar human genetics. Today chromosomes are understood as macromolecular assemblies and are analyzed with a variety of molecular techniques. Yet for much of the twentieth century, researchers studied chromosomes by looking through a microscope. Unlike any other technique, chromosome analysis offered a direct glimpse of the complete human genome, opening up seemingly endless possibilities for observation and intervention. Critics, however, countered that visual evidence was not enough and pointed to the need to understand the molecular mechanisms. Telling this history in full for the first time, Soraya de Chadarevian argues that the often bewildering variety of observations made under the microscope were central to the study of human genetics. Making space for microscope-based practices alongside molecular approaches, de Chadarevian analyzes the close connections between genetics and an array of scientific, medical, ethical, legal, and policy concerns in the atomic age. By exploring the visual evidence provided by chromosome research in the context of postwar biology and medicine, Heredity under the Microscope sheds new light on the cultural history of the human genome.
Download or read book Freezing Fertility written by Lucy van de Wiel and published by NYU Press. This book was released on 2020-12-15 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcomed as liberation and dismissed as exploitation, egg freezing (oocyte cryopreservation) has rapidly become one of the most widely-discussed and influential new reproductive technologies of this century. In Freezing Fertility, Lucy van de Wiel takes us inside the world of fertility preservation—with its egg freezing parties, contested age limits, proactive anticipations and equity investments—and shows how the popularization of egg freezing has profound consequences for the way in which female fertility and reproductive aging are understood, commercialized and politicized. Beyond an individual reproductive choice for people who may want to have children later in life, Freezing Fertility explores how the rise of egg freezing also reveals broader cultural, political and economic negotiations about reproductive politics, gender inequities, age normativities and the financialization of healthcare. Van de Wiel investigates these issues by analyzing a wide range of sources—varying from sparkly online platforms to heart-breaking court cases and intimate autobiographical accounts—that are emblematic of each stage of the egg freezing procedure. By following the egg’s journey, Freezing Fertility examines how contemporary egg freezing practices both reflect broader social, regulatory and economic power asymmetries and repoliticize fertility and aging in ways that affect the public at large. In doing so, the book explores how the possibility of egg freezing shifts our relation to the beginning and end of life.

Download or read book Empire Under the Microscope written by Emilie Taylor-Pirie and published by Springer Nature. This book was released on 2021-11-26 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book considers science and empire, and the stories we tell ourselves about them. Using British Nobel laureate Ronald Ross (1857-1932) and his colleagues as access points to a wider professional culture, Empire Under the Microscope explores the cultural history of parasitology and its relationships with the literary and historical imagination between 1885 and 1935. Emilie Taylor-Pirie examines a wealth of archival material including medical lectures, scientific publications, popular biography, and personal and professional correspondence, alongside novels, poems, newspaper articles, and political speeches, to excavate the shared vocabularies of literature and medicine. She demonstrates how forms such as poetry and biography; genres such as imperial romance and detective fiction; and modes such as adventure and the Gothic, together informed how tropical diseases, their parasites, and their vectors, were understood in relation to race, gender, and nation. From Ancient Greece, to King Arthur’s Knights, to the detective work of Sherlock Holmes, parasitologists manipulated literary and historical forms of knowledge in their professional self-fashioning to create a modern mythology that has a visible legacy in relationships between science and society today.

Download or read book Visions of Cell Biology written by Karl S. Matlin and published by University of Chicago Press. This book was released on 2018-01-19 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although modern cell biology is often considered to have arisen following World War II in tandem with certain technological and methodological advances—in particular, the electron microscope and cell fractionation—its origins actually date to the 1830s and the development of cytology, the scientific study of cells. By 1924, with the publication of Edmund Vincent Cowdry’s General Cytology, the discipline had stretched beyond the bounds of purely microscopic observation to include the chemical, physical, and genetic analysis of cells. Inspired by Cowdry’s classic, watershed work, this book collects contributions from cell biologists, historians, and philosophers of science to explore the history and current status of cell biology. Despite extraordinary advances in describing both the structure and function of cells, cell biology tends to be overshadowed by molecular biology, a field that developed contemporaneously. This book remedies that unjust disparity through an investigation of cell biology’s evolution and its role in pushing forward the boundaries of biological understanding. Contributors show that modern concepts of cell organization, mechanistic explanations, epigenetics, molecular thinking, and even computational approaches all can be placed on the continuum of cell studies from cytology to cell biology and beyond. The first book in the series Convening Science: Discovery at the Marine Biological Laboratory, Visions of Cell Biology sheds new light on a century of cellular discovery.
