The Hayflick Limit by Matthew Tierney Pdf

To be human is to cope with knowing. In the early 1960s, Leonard Hayflick determined that healthy cells can divide only a finite number of times. Known as the Hayflick Limit, it sets an unsurpassable lifespan for our species at just over 120 years. Shifting focus between the limits of the microscope and the limits of the telescope, Matthew Tierney gives voice to a range of characters who scrape out meaning in a carnivalesque universe, one that has birthed black holes and Warner Bros. cartoons, murky market economies, murkier quantum laws, Vincent Price, Molotov cocktails, seedless grapes, Area 51 and competing Theories of Everything.

The Vaccine Race by Meredith Wadman Pdf

"A real jewel of science history...brims with suspense and now-forgotten catastrophe and intrigue...Wadman’s smooth prose calmly spins a surpassingly complicated story into a real tour de force."—The New York Times “Riveting . . . [The Vaccine Race] invites comparison with Rebecca Skloot's 2007 The Immortal Life of Henrietta Lacks.”—Nature The epic and controversial story of a major breakthrough in cell biology that led to the conquest of rubella and other devastating diseases. Until the late 1960s, tens of thousands of American children suffered crippling birth defects if their mothers had been exposed to rubella, popularly known as German measles, while pregnant; there was no vaccine and little understanding of how the disease devastated fetuses. In June 1962, a young biologist in Philadelphia, using tissue extracted from an aborted fetus from Sweden, produced safe, clean cells that allowed the creation of vaccines against rubella and other common childhood diseases. Two years later, in the midst of a devastating German measles epidemic, his colleague developed the vaccine that would one day wipe out homegrown rubella. The rubella vaccine and others made with those fetal cells have protected more than 150 million people in the United States, the vast majority of them preschoolers. The new cells and the method of making them also led to vaccines that have protected billions of people around the world from polio, rabies, chicken pox, measles, hepatitis A, shingles and adenovirus. Meredith Wadman’s masterful account recovers not only the science of this urgent race, but also the political roadblocks that nearly stopped the scientists. She describes the terrible dilemmas of pregnant women exposed to German measles and recounts testing on infants, prisoners, orphans, and the intellectually disabled, which was common in the era. These events take place at the dawn of the battle over using human fetal tissue in research, during the arrival of big commerce in campus labs, and as huge changes take place in the laws and practices governing who “owns” research cells and the profits made from biological inventions. It is also the story of yet one more unrecognized woman whose cells have been used to save countless lives. With another frightening virus--measles--on the rise today, no medical story could have more human drama, impact, or urgency than The Vaccine Race.

How and why We Age by Leonard Hayflick Pdf

"How long can humans live? Is immortality possible? Just what is the aging process? The aging and inevitable death of the human body have inspired more myths and outrageous quackery than anything else subject to scientific inquiry. . . . Now comes a most fascinating book, insightful and scholarly, to provide what answers have emerged so far." --San Francisco Chronicle Here, at last, preeminent cell biologist Leonard Hayflick presents the truth about human aging. Based on more than thirty years of pioneering research in the field, How and Why We Age explores not only how our major biological systems change as we grow older, but also examines the intangible alterations in our modes of thinking and feeling, our moods and sexual desires, our personality traits and our memories. With the immediacy of the latest scientific discoveries, Dr. Hayflick explains how aging affects every part of the body, and dispels many of the most persistent aging myths, to show that: * Hearts do not naturally get weaker with age. * Regular exercise and a low-fat diet won't slow aging. * Curing cancer would only add two years to the average sixty-five-year-old American life. Curing heart disease, however would add fourteen years. * Only five percent of people over the age of sixty-five are in nursing homes * No human has lived--or probably can live--past 120 years. Gracefully written, clearly organized, and packed with essential facts and statistics, How and Why We Age is a landmark study of the aging process for readers of all ages. "Written in clear, nontechnical language, it is an excellent introduction to the scientific and demographic literature on this multifacetedsubject." --Nature

Cellular Ageing and Replicative Senescence by Suresh I.S. Rattan,Leonard Hayflick Pdf

This book covers the origins and subsequent history of research results in which attempts have been made to clarify issues related to cellular ageing, senescence, and age-related pathologies including cancer. Cellular Ageing and Replicative Senescence revisits more than fifty-five years of research based on the discovery that cultured normal cells are mortal and the interpretation that this phenomenon is associated with the origins of ageing. The mortality of normal cells and the immortality of cancer cells were also reported to have in vivo counterparts. Thus began the field of cytogerontology. Cellular Ageing and Replicative Senescence is organized into five sections: history and origins; serial passaging and progressive ageing; cell cycle arrest and senescence; system modulation; and recapitulation and future expectations. These issues are discussed by leading thinkers and researchers in biogerontology and cytogerontology. This collection of articles provides state-of-the-art information, and will encourage students, teachers, health care professionals and others interested in the biology of ageing to explore the fascinating and challenging question of why and how our cells age, and what can and cannot be done about it.

Intrinsic mutagenesis by Burnet MacFarlane Pdf

This book is something which almost accidentally has developed very differently from how it was initially planned. The intention was to elaborate the part played by the immune system in ageing with the role of the thymus as central theme. It was to be essentially an expansion of a lecture I gave in 1970 and would inevitably have been concerned with much the same material as Walford's book, The Immunologic Theory of Aging, though from a different slant. What changed its character arose from a series of attempts to find logical connection between two findings that most gerontologists regard as axiomatic: that the lifespan of a mammal is genetically determined, and that the actual process of ageing is an accumulation of genetic error, of somatic mutations. It is possible that the connection is so indirect, circuitous and multiform that generations of detailed and unattractive research will be needed to elucidate it, or, more likely, the whole matter discarded as a non-problem. But a more inspiring approach does seem possible. The working hypothesis, which halfway through its writing became the new central theme of the book, arose when I was a member of a committee appointed by the Australian Academy of Science at the request of the Australian Government to advise on the danger from French nuclear tests in the South Pacific.

She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells—taken without her knowledge—became one of the most important tools in medicine: The first “immortal” human cells grown in culture, which are still alive today, though she has been dead for more than sixty years. HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects; helped lead to important advances like in vitro fertilization, cloning, and gene mapping; and have been bought and sold by the billions. Yet Henrietta Lacks remains virtually unknown, buried in an unmarked grave. Henrietta’s family did not learn of her “immortality” until more than twenty years after her death, when scientists investigating HeLa began using her husband and children in research without informed consent. And though the cells had launched a multimillion-dollar industry that sells human biological materials, her family never saw any of the profits. As Rebecca Skloot so brilliantly shows, the story of the Lacks family—past and present—is inextricably connected to the dark history of experimentation on African Americans, the birth of bioethics, and the legal battles over whether we control the stuff we are made of. Over the decade it took to uncover this story, Rebecca became enmeshed in the lives of the Lacks family—especially Henrietta’s daughter Deborah. Deborah was consumed with questions: Had scientists cloned her mother? Had they killed her to harvest her cells? And if her mother was so important to medicine, why couldn’t her children afford health insurance? Intimate in feeling, astonishing in scope, and impossible to put down, The Immortal Life of Henrietta Lacks captures the beauty and drama of scientific discovery, as well as its human consequences.

Boon and Bane of not Being Subject to the Hayflick Limit by Miriam Herbert Pdf

Pre-University Paper from the year 2014 in the subject Biology - Cytology, grade: 15 Punkte = 1,0, , language: English, abstract: All living things have to die. This fundamental truth is held to apply even to the smallest unit of life – cells. However, there is a phenomenon that is sometimes called biological immortality. It refers to cells that live beyond their proclaimed life span, which is roughly set by the Hayflick limit. All cancer cells have acquired this property; they divide indefinitely, which is the essential problem with cancer cells. On the other hand, researchers are very much interested in the molecular mechanism behind this property to may be able to use it to extend life and rejuvenate cells. Cells that are not subject to the Hayflick limit are generally seen as a threat to the human body, however, they are interesting subjects of experiments and scientists have already learned a great deal of knowledge by studying these mutants and continue to gain more important insights into the functioning of any kind of human body cell. Immortal cells can be boon and bane for humankind. Certain aspects of this issue will be discussed.

Public Enemy Number 1--stress by Herman Todorov,Robert Nadler,Igor N. Todorov Pdf

It can slowly drain the life force from your body over time. Or kill swiftly without warning. But you will never find it on a medical chart or see it listed on a death certificate. It's called stress. It exacts a tremendous toll on our lives. It saps our strength, robs our youth and makes us old before our time. We encounter it day in and day out, yet do little, if anything about it. It's no wonder. In today's 'pressure cooker society', the average lunch hour lasts about 11 minutes. Dinner is often consumed in less than 6 minutes (usually seated in front of the television). The average workday can last 10 hours or more. We seem to be living in a society where there's virtually no time for quality time. Strictly speaking, stress itself is not among the direct causes of ageing, yet it plays an extremely important role in the ageing process. It is a powerful force that serves as a catalyst in every known mechanism that causes us to age. Readers might be surprised to find out that this book has as much to do with ageing, life extension and specific measures we can take to postpone the inevitable as it does with stress. The fact is that stress and ageing are inextricably bound together.

Chance, Development, and Aging by Caleb Ellicott Finch,T. B. L. Kirkwood Pdf

Chance, Development, and Aging analyzes a subject that has been largelyignored until now: the sources of individual variations in development and agingthat cannot be attributed to genes or the external environment. And by doing so,this book develops new insight on aging and the individual. Gathering andscrutinizing evidence from diverse sources, the authors examine thosedifferences in individuals that arise during development and those that mightinfluence outcomes of aging. Through their research, they pose a new set ofquestions about the contribution of chance events during development, andalthough chance variations during development are well known within thesub-fields of developmental biology, there has been little recognition of theiraffects on variations in adult form and function. Here, the authors confrontthis issue with a fascinating hypothesis: chance variations in form andfunction, arising through development, affect individual base-line functions andindividual responses to the external environment and so modify outcomes ofaging. This book will undoubtedly benefit gerontologists, geneticists,reproductive biologists, and physiologists, and it will fascinate all thoseinterested in the outcomes of aging.

Evolutionary Biology of Aging by Michael R. Rose Pdf

This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.

Encyclopedia of Aging and Public Health by Sana Loue,Martha Sajatovic Pdf

Americans are living longer, and the elder population is growing larger. To meet the ongoing need for quality information on elder health, the Encyclopedia of Aging and Public Health combines multiple perspectives to offer readers a more accurate and complete picture of the aging process. The book takes a biopsychosocial approach to the complexities of its subject. In-depth introductory chapters include coverage on a historical and demographic overview of aging in America, a guide to biological changes accompanying aging, an analysis of the diversity of the U.S. elder population, legal issues commonly affecting older adults, and the ethics of using cognitively impaired elders in research. From there, over 425 entries cover the gamut of topics, trends, diseases, and phenomena: -Specific populations, including ethnic minorities, custodial grandparents, and centenarians -Core medical conditions associated with aging, from cardiac and pulmonary diseases to Parkinson’s and Alzheimer’s -Mental and emotional disorders -Drugs/vitamins/alternative medicine -Disorders of the eyes, feet, and skin -Insomnia and sleep disorders; malnutrition and eating disorders -Sexual and gender-related concerns -And a broad array of social and political issues, including access to care, abuse/neglect, veterans’ affairs, and assisted suicide Entries on not-quite-elders’ concerns (e.g., midlife crisis, menopause) are featured as well. And all chapters and entries include references and resource lists. The Encyclopedia has been developed for maximum utility to clinicians, social workers, researchers, and public health professionals working with older adults. Its multidisciplinary coverage and scope of topics make this volume an invaluable reference for academic and public libraries.

Probably Inevitable by Matthew Tierney Pdf

Winner of the Trillium Book Award for Poetry (2013) These are high-energy poems, riddled with wit and legerdemain and jolted by the philosophy and science of time. "Time's not the market, it's the bustle; / not the price but worth," he writes, sailing through the rhythms and algorithms of a world made concrete by Samuel Johnson, before it was undone by Niels Bohr. Matthew Tierney's narrators grapple with the gap between what's seen and what's experienced, their minds tuned to one (probably) inevitable truth: the more I understand, the more I understand I'm alone. If it were necessary to tell someone where I am, I'd say the spheres of Kepler resonate like icicles. I'd say I have loved. Matthew Tierney is the author of the Trillium Award–nominated The Hayflick Limit and Full Speed through the Morning Dark. He lives in Toronto, Ontario.

Neuroblastoma by Chandrika Gowda Pdf

Neuroblastoma (NBL) is the most common extracranial solid tumor of childhood, with about 700 new cases of neuroblastoma seen each year in the United States. The 5-year survival rate for children with high-risk NBL is only 50-60%, and this survival rate has not improved over the last 10 years. High-risk patients receive multimodality treatment, including chemotherapy, surgery, radiation therapy, biologic therapy and immunotherapy, all of which are associated with significant morbidity. Recent years have seen many advances in treatment of neuroblastoma, including therapeutic MIBG, immunotherapy, and personalized targeted therapy based on the genetic alterations seen in the tumor. The primary objective of this book is to provide the readers with a comprehensive review of neuroblastoma, from clinical aspects and the currently available treatment to recent advancements and future directions in the field of NBL treatment. The topics and chapters have been compiled keeping in mind a diverse group of readers in different areas of specialty such as pediatric oncology, surgery, radiation oncology, and immunology, as well as physician scientists and basic researchers working in the field of neuroblastoma.
