Download or read book Apoptosis written by C. S. Potten and published by Cambridge University Press. This book was released on 2004-08-16 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of programmed cell death, or apoptosis, has exploded into a major scientific field of interest for cell biologists, oncologists, and many other biomedical researchers. Apoptosis occurs throughout the lifetime of most multicellular organisms. During development, for example, the selective death of cells is vital to remove tissue between the digits to produce fingers and toes. Apoptosis is also necessary to destroy cells that represent a threat to the integrity of the organism, for example cells infected by a virus. In many cancers the genes regulating apoptosis are defective, producing immortal, continuously proliferating cells. This book discusses the philosophical and technical difficulties in defining the moment of death for a cell, as well as the biological implications and significance of programmed cell death. Recent developments in the genetic control and interacting gene networks associated with apoptosis are presented. The book is written for advanced undergraduate and postgraduate students, and is highly illustrated to aid understanding.
Book Synopsis Remembering and Disremembering the Dead by : Floris Tomasini
Download or read book Remembering and Disremembering the Dead written by Floris Tomasini and published by Springer. This book was released on 2017-08-01 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 licence. This book is a multidisciplinary work that investigates the notion of posthumous harm over time. The question what is and when is death, affects how we understand the possibility of posthumous harm and redemption. Whilst it is impossible to hurt the dead, it is possible to harm the wishes, beliefs and memories of persons that once lived. In this way, this book highlights the vulnerability of the dead, and makes connections to a historical oeuvre, to add critical value to similar concepts in history that are overlooked by most philosophers. There is a long historical view of case studies that illustrate the conceptual character of posthumous punishment; that is, dissection and gibbetting of the criminal corpse after the Murder Act (1752), and those shot at dawn during the First World War. A long historical view is also taken of posthumous harm; that is, body-snatching in the late Georgian period, and organ-snatching at Alder Hey in the 1990s.
Book Synopsis The Revolutionary Origins of Life and Death by : Pierre M. Durand
Download or read book The Revolutionary Origins of Life and Death written by Pierre M. Durand and published by University of Chicago Press. This book was released on 2020-12-09 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of why an individual would actively kill itself has long been an evolutionary mystery. Pierre M. Durand’s ambitious book answers this question through close inspection of life and death in the earliest cellular life. As Durand shows us, cell death is a fascinating lens through which to examine the interconnectedness, in evolutionary terms, of life and death. It is a truism to note that one does not exist without the other, but just how does this play out in evolutionary history? These two processes have been studied from philosophical, theoretical, experimental, and genomic angles, but no one has yet integrated the information from these various disciplines. In this work, Durand synthesizes cellular studies of life and death looking at the origin of life and the evolutionary significance of programmed cellular death. The exciting and unexpected outcome of Durand’s analysis is the realization that life and death exhibit features of coevolution. The evolution of more complex cellular life depended on the coadaptation between traits that promote life and those that promote death. In an ironic twist, it becomes clear that, in many circumstances, programmed cell death is essential for sustaining life.
Book Synopsis The Biology of Death by : André Klarsfeld
Download or read book The Biology of Death written by André Klarsfeld and published by Cornell University Press. This book was released on 2004 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do we die? Do all living creatures share this fate? Is the body's slow degradation with the passage of time unavoidable, or can the secrets of longevity be unlocked? Over the past two decades, scientists studying the workings of genes and cells have uncovered some of the clues necessary to solve these mysteries. In this fascinating and accessible book, two neurobiologists share the often-surprising findings from that research, including the possibility that aging and natural death may not be forever a certainty for most living beings. André Klarsfeld and Frédéric Revah discuss in detail the latest scientific findings and views on death and longevity. They challenge many popular assumptions, such as the idea that the death of individual organisms serves to rejuvenate species or that death and sexual reproduction are necessarily linked. Finally, they describe current experimental approaches to postpone natural death in lower organisms as well as in mammals. Are all organisms that survive until late in life condemned to a "natural" death, as a consequence of aging, even if they live in a well-protected, supportive environment? The variability of the adult life span--from a few hours for some insects to more than a millennium for the sequoia and thirteen times that for certain wild berry bushes--challenges the notion that death is unavoidable. Evolutionary theory helps explain why and how some species have achieved biological mechanisms that seemingly allow them to resist time. Death cannot be understood without looking into cells--the essential building blocks of life. Intriguingly, at the level of cells, death is not always an accident; it is often programmed as an indispensable aspect of life, which benefits the organism as a whole.
Download or read book Mortal Minds written by Gerald M. Woerlee and published by Prometheus Books. This book was released on 2010-06-03 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: With its easy-to-read and personal style, this book provides some intriguing new explanations of the physiology of death and the dying experience.--Susan Blackmore, PhD, Author of Dying to LiveDying is the last conscious experience undergone by each person. But what do the dying experience? In the last few decades a good deal of publicity has surrounded people who have been close to death and then reported intense experiences that seem to suggest a supernatural existence beyond death. Does the conscious mind somehow continue to exist after the body has passed away? Mortal Minds answers these questions.Dr. G. M. Woerlee explains how the normal functioning of the human body near death can generate beliefs in the reality of the supernatural and life after death. An anesthesiologist with more than twenty years of hospital experience, Dr. Woerlee has been struck over the years by the similarities between the body's symptoms under anesthesia and its reactions near death. Among the issues he addresses are the sensations of being disembodied that those near death often describe, the perception that mind and body are separate components of existence, whether there is such a thing as a soul, the physical effects of decreased oxygen to the brain, and the visions that the dying sometimes report, from rapturous experiences of eternal peace to diabolical dreams.While not dismissing near death experiences as mere hallucinations, Dr. Woerlee is also careful to point out that even powerful psychological impressions by themselves do not constitute scientific proof of life after death. Taking this balanced, objective stance, he succeeds in conveying a better understanding of the dying process and helping us all to realize the nature of these final experiences.G. M. Woerlee (Leiden, The Netherlands) is an anesthesiologist affiliated with the Rijnland Hospital in Leiderdorp, The Netherlands, and the author of two books on anesthesiology.
Book Synopsis The Evolution of Death by : Stanley Shostak
Download or read book The Evolution of Death written by Stanley Shostak and published by State University of New York Press. This book was released on 2012-02-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Evolution of Death, the follow-up to Becoming Immortal: Combining Cloning and Stem-Cell Therapy, also published by SUNY Press, Stanley Shostak argues that death, like life, can evolve. Observing that literature, philosophy, religion, genetics, physics, and gerontology still struggle to explain why we die, Shostak explores the mystery of death from a biological perspective. Death, Shostak claims, is not the end of a linear journey, static and indifferent to change. Instead, he suggests, the current efforts to live longer have profoundly affected our ecological niche, and we are evolving into a long-lived species. Pointing to the artificial means currently used to prolong life, he argues that as we become increasingly juvenilized in our adult life, death will become significantly and evolutionarily delayed. As bodies evolve, the embryos of succeeding generations may be accumulating the stem cells that preserve and restore, providing the resources necessary to live longer and longer. If trends like this continue, Shostak contends, future human beings may join the ranks of other animals with indefinite life spans.
Download or read book Cell Death written by Douglas R. Green and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A million cells in our bodies die every second--they commit suicide by activating a process called apoptosis or other forms of programmed cell death. These mechanisms are essential for survival of the body as a whole and play critical roles in various developmental processes, the immune system, and cancer. In this second edition of Douglas Green's essential book on cell death, Green retains the bottom-up approach of the first edition, starting with the enzymes that carry out the execution (caspases) and their cellular targets before examining the machinery that connects them to signals that cause cell death. He also describes the roles of cell death in development, neuronal selection, and the development of self-tolerance in the immune system, as well as how the body uses cell death to defend against cancer. The new edition is fully updated to cover the many recent advances in our understanding of the death machinery and signals that control cell death. These include the mechanisms regulating necroptosis, mitophagy, and newly identified processes, such as ferroptosis. The book will thus be of great interest to researchers actively working in the field, as well as biologists and undergraduates encountering the topic for the first time.

Download or read book Tetrapyrroles written by Martin Warren and published by Springer Science & Business Media. This book was released on 2009-12-21 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excluding the biological polymers proteins, lipids and nucleic acids, modified tetrapyrroles are the biological molecules that have had the greatest impact on the evolution of life over the past 4 billion years. They are involved in a wide variety of fundamental processes that underpin central primary metabolism in all kingdoms of life, from photosynthesis to methanogenesis. Moreover, they bring colour into the world and it is for this reason that these compounds have been appropriately dubbed the ‘pigments of life’. To understand how and why these molecules have been so universally integrated into the life processes one has to appreciate the chemical properties of the tetrapyrrole scaffold and, where appropriate, the chemical characteristics of the centrally chelated metal ion. This book addresses why these molecules are employed in Nature, how they are made and what happens to them after they have finished their usefulness.

Download or read book Apoptosis written by Michael D. Jacobson and published by Frontiers in Molecular Biology. This book was released on 2002 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of cells within the human body is very tightly regulated: too many and we can develop cancer, too few and we may lose cells that we cannot replace. The number of cells is controlled by several different mechanisms in different tissues, but all are triggered to commit suicide should too many be in one place at one time, or become damaged. This book examines how this process of cell suicide (apoptosis) is regulated, and how our understanding of this process may lead to novel treatments for a wide variety of human diseases.
Book Synopsis Death and the Regeneration of Life by : Maurice Bloch
Download or read book Death and the Regeneration of Life written by Maurice Bloch and published by Cambridge University Press. This book was released on 1982-12-30 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a classical anthropological paradox that symbols of rebirth and fertility are frequently found in funerary rituals throughout the world. The original essays collected here re-examine this phenomenon through insights from China, India, New Guinea, Latin America, and Africa. The contributors, each a specialist in one of these areas, have worked in close collaboration to produce a genuinely innovative theoretical approach to the study of the symbolism surrounding death, an outline of which is provided in an important introduction by the editors. The major concern of the volume is the way in which funerary rituals dramatically transform the image of life as a dialectic flux involving exchange and transaction, marriage and procreation, into an image of a still, transcendental order in which oppositions such as those between self and other, wife-giver and wife-taker, Brahmin and untouchable, birth and therefore death have been abolished. This transformation often involves a general devaluation of biology, and, particularly, of sexuality, which is contrasted with a more spiritual and controlled source of life. The role of women, who are frequently associated with biological processes, mourning and death pollution, is often predominant in funerary rituals, and in examining this book makes a further contribution to the understanding of the symbolism of gender. The death rituals and the symbolism of rebirth are also analysed in the context of the political processes of the different societies considered, and it is argued that social order and political organisation may be legitimated through an exploitation of the emotions and biology.
Book Synopsis DMT: The Spirit Molecule by : Rick Strassman
Download or read book DMT: The Spirit Molecule written by Rick Strassman and published by Simon and Schuster. This book was released on 2000-12-01 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clinical psychiatrist explores the effects of DMT, one of the most powerful psychedelics known. • A behind-the-scenes look at the cutting edge of psychedelic research. • Provides a unique scientific explanation for the phenomenon of alien abduction experiences. From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected sixty volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences. Many reported convincing encounters with intelligent nonhuman presences, aliens, angels, and spirits. Nearly all felt that the sessions were among the most profound experiences of their lives. Strassman's research connects DMT with the pineal gland, considered by Hindus to be the site of the seventh chakra and by Rene Descartes to be the seat of the soul. DMT: The Spirit Molecule makes the bold case that DMT, naturally released by the pineal gland, facilitates the soul's movement in and out of the body and is an integral part of the birth and death experiences, as well as the highest states of meditation and even sexual transcendence. Strassman also believes that "alien abduction experiences" are brought on by accidental releases of DMT. If used wisely, DMT could trigger a period of remarkable progress in the scientific exploration of the most mystical regions of the human mind and soul.
Book Synopsis Brain Death and Disorders of Consciousness by : Calixto Machado
Download or read book Brain Death and Disorders of Consciousness written by Calixto Machado and published by Springer Science & Business Media. This book was released on 2004-03-31 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although some decades have passed, there are still worldwide controversies about a concept of human death on neurological grounds. There are also disagreements on the diagnostic criteria for brain death, whether clinical alone or clinical plus ancillary tests. Moreover, some scholars who were strong defenders of a brain-based standard of death are now favoring a circulatory-respiratory standard. The study of coma is extremely important because lesions of the brain are responsible for quality of life in patients or cause of death. The main goal of Brain Death and Disorders of Consciousness is to provide a suitable scientific platform to discuss all topics related to human death and coma.
