Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. 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 Fluoxetine written by Graziano Pinna and published by . This book was released on 2015-04-01 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluoxetine, best known by the trade name Prozac®, unlike other psychotropic drugs whose effects were serendipitously stumbled upon, was the first developed for a precise mechanism of action, that is, the ability to selectively inhibit serotonin reuptake, based upon the theory that increasing the availability of serotonin would treat major depression. Once approved by the FDA in 1987, fluoxetine quickly became the most prescribed psychotropic drug worldwide and its success in improving mood disorders has triggered the development of a large number of congener molecules, commonly known as SSRIs after their purported mechanism of action. However, a quarter of a century after its development, the idea that fluoxetine asserts its positive behavioral effect through inhibition of serotonergic reuptake is not firmly established. This book reviews several preclinical and clinical reports suggesting that the pharmacological effects of fluoxetine may be mediated by means other than the regulation of serotonin, including the regulation of gene expression, modifying epigenetic mechanisms as well as modifying microRNAs. One of the most prominent mechanisms for the therapeutic relevance of fluoxetine relates to influencing neuroplasticity by enhancing neurotropic factors, including BDNF signaling and altering adult neurogenesis. The ability of fluoxetine to rapidly increase neurosteroid levels accounts for the fast anxiolytic effects of this drug. Fluoxetine action at sigma-1 receptor or modulating glutamatergic neurotransmission as well as the combination of fluoxetine with other psychotropic drugs is discussed in relation to its therapeutic effects. While fluoxetine was primarily prescribed as an antidepressant, this drug currently represents a treatment of choice for a broad spectrum of psychiatric disorders, including post-traumatic stress disorder and a range of anxiety disorders. This drug even possesses analgesic actions and is a valuable therapy for stroke. This book also highlights emerging evidence on the gender-specific effects of fluoxetine, its potential adverse features, including its addiction liability in combination with psychostimulants, and the impact of perinatal fluoxetine exposure.
Download or read book Astro Turf written by M. G. Lord and published by Bloomsbury Publishing USA. This book was released on 2009-05-26 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: A daughter's journey to rediscover her father and understand the culture of space engineers During the late 1960s, while M. G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery. Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."

Download or read book The Charisma Machine written by Morgan G. Ames and published by MIT Press. This book was released on 2019-11-19 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating examination of technological utopianism and its complicated consequences. In The Charisma Machine, Morgan Ames chronicles the life and legacy of the One Laptop per Child project and explains why—despite its failures—the same utopian visions that inspired OLPC still motivate other projects trying to use technology to “disrupt” education and development. Announced in 2005 by MIT Media Lab cofounder Nicholas Negroponte, One Laptop per Child promised to transform the lives of children across the Global South with a small, sturdy, and cheap laptop computer, powered by a hand crank. In reality, the project fell short in many ways—starting with the hand crank, which never materialized. Yet the project remained charismatic to many who were captivated by its claims of access to educational opportunities previously out of reach. Behind its promises, OLPC, like many technology projects that make similarly grand claims, had a fundamentally flawed vision of who the computer was made for and what role technology should play in learning. Drawing on fifty years of history and a seven-month study of a model OLPC project in Paraguay, Ames reveals that the laptops were not only frustrating to use, easy to break, and hard to repair, they were designed for “technically precocious boys”—idealized younger versions of the developers themselves—rather than the children who were actually using them. The Charisma Machine offers a cautionary tale about the allure of technology hype and the problems that result when utopian dreams drive technology development.
Download or read book After Life written by Eugene Thacker and published by University of Chicago Press. This book was released on 2010-11-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life is one of our most basic concepts, and yet when examined directly it proves remarkably contradictory and elusive, encompassing both the broadest and the most specific phenomena. We can see this uncertainty about life in our habit of approaching it as something at once scientific and mystical, in the return of vitalisms of all types, and in the pervasive politicization of life. In short, life seems everywhere at stake and yet is nowhere the same. In After Life, Eugene Thacker clears the ground for a new philosophy of life by recovering the twists and turns in its philosophical history. Beginning with Aristotle’s originary formulation of a philosophy of life, Thacker examines the influence of Aristotle’s ideas in medieval and early modern thought, leading him to the work of Immanuel Kant, who notes the inherently contradictory nature of “life in itself.” Along the way, Thacker shows how early modern philosophy’s engagement with the problem of life affects thinkers such as Gilles Deleuze, Georges Bataille, and Alain Badiou, as well as contemporary developments in the “speculative turn” in philosophy. At a time when life is categorized, measured, and exploited in a variety of ways, After Life invites us to delve deeper into the contours and contradictions of the age-old question, “what is life?”

Download or read book Forever Barbie The Unauthorized Biography of a Real Doll written by M.G. Lord and published by Liveright Publishing. This book was released on 2024-03-05 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barbie is a strong, independent doll. But is she a feminist icon? It’s complicated. Since her introduction in 1959, Barbie’s impact has been revolutionary. Far from being a toy designed by men to oppress women, she was a toy invented by women to teach women what was expected of them, for better or for worse. Whether tarred-and-glittered as antifeminist puffery or celebrated as a feminist icon (or, at any rate, an important cultural touchstone in understanding feminism) Barbie has undeniably influenced generations of girls. In Forever Barbie, cultural critic, investigative journalist, and first-generation Barbie owner M. G. Lord uncovers the surprising story behind Barbie’s smash success. Revealing her low origins as “Bild Lilli,” a risqué doll for adults sold as a gag gift in postwar Germany, Forever Barbie traces Barbie’s development and transformation, through countless makeovers and career changes, into an international pop culture icon and now “traditional toy.” Though not every doll in the line has been a hit—with pregnant Midge and Growing up Skipper among the more intriguing disasters—Barbie’s endurance, Lord writes, speaks as much to Mattel’s successful marketing as it does to our society’s overall ambivalence toward femininity. With new accessories, including a preface on the latest developments in the Barbieverse, Forever Barbie “will make you think of America’s most celebrated plastic doll in ways you never have before” (Susan Faludi).
Download or read book Committee on Military Nutrition Research written by Institute of Medicine and published by National Academies Press. This book was released on 1999-08-04 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military Operational Medicine Program of USAMRMC at Fort Detrick, Maryland. The CMNR has submitted five workshop reports (plus two preliminary reports), including one that is a joint project with the Subcommittee on Body Composition, Nutrition, and Health of Military Women; three letter reports, and one brief report, all with recommendations, to the Commander, U.S. Army Medical Research and Materiel Command, since September 1995 and has a brief report currently in preparation. These reports are summarized in the following activity report with synopses of additional topics for which reports were deferred pending completion of military research in progress. This activity report includes as appendixes the conclusions and recommendations from the nine reports and has been prepared in a fashion to allow rapid access to committee recommendations on the topics covered over the time period.
Download or read book The Book of Shells written by M.G. Harasewych and published by University of Chicago Press. This book was released on 2014-12-10 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who among us hasn’t marveled at the diversity and beauty of shells? Or picked one up, held it to our ear, and then gazed in wonder at its shape and hue? Many a lifelong shell collector has cut teeth (and toes) on the beaches of the Jersey Shore, the Outer Banks, or the coasts of Sanibel Island. Some have even dived to the depths of the ocean. But most of us are not familiar with the biological origin of shells, their role in explaining evolutionary history, and the incredible variety of forms in which they come. Shells are the external skeletons of mollusks, an ancient and diverse phylum of invertebrates that are in the earliest fossil record of multicellular life over 500 million years ago. There are over 100,000 kinds of recorded mollusks, and some estimate that there are over amillion more that have yet to be discovered. Some breathe air, others live in fresh water, but most live in the ocean. They range in size from a grain of sand to a beach ball and in weight from a few grams to several hundred pounds. And in this lavishly illustrated volume, they finally get their full due. The Book of Shells offers a visually stunning and scientifically engaging guide to six hundred of the most intriguing mollusk shells, each chosen to convey the range of shapes and sizes that occur across a range of species. Each shell is reproduced here at its actual size, in full color, and is accompanied by an explanation of the shell’s range, distribution, abundance, habitat, and operculum—the piece that protects the mollusk when it’s in the shell. Brief scientific and historical accounts of each shell and related species include fun-filled facts and anecdotes that broaden its portrait. The Matchless Cone, for instance, or Conus cedonulli, was one of the rarest shells collected during the eighteenth century. So much so, in fact, that a specimen in 1796 was sold for more than six times as much as a painting by Vermeer at the same auction. But since the advent of scuba diving, this shell has become far more accessible to collectors—though not without certain risks. Some species of Conus produce venom that has caused more than thirty known human deaths. The Zebra Nerite, the Heart Cockle, the Indian Babylon, the Junonia, the Atlantic Thorny Oyster—shells from habitats spanning the poles and the tropics, from the highest mountains to the ocean’s deepest recesses, are all on display in this definitive work.
Download or read book I Had a Black Dog written by Matthew Johnstone and published by Hachette UK. This book was released on 2012-03-01 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'I Had a Black Dog says with wit, insight, economy and complete understanding what other books take 300 pages to say. Brilliant and indispensable.' - Stephen Fry 'Finally, a book about depression that isn't a prescriptive self-help manual. Johnston's deftly expresses how lonely and isolating depression can be for sufferers. Poignant and humorous in equal measure.' Sunday Times There are many different breeds of Black Dog affecting millions of people from all walks of life. The Black Dog is an equal opportunity mongrel. It was Winston Churchill who popularized the phrase Black Dog to describe the bouts of depression he experienced for much of his life. Matthew Johnstone, a sufferer himself, has written and illustrated this moving and uplifting insight into what it is like to have a Black Dog as a companion and how he learned to tame it and bring it to heel.
Download or read book Look Me in the Eye written by John Elder Robison and published by Crown. This book was released on 2008-09-09 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER “As sweet and funny and sad and true and heartfelt a memoir as one could find.” —from the foreword by Augusten Burroughs Ever since he was young, John Robison longed to connect with other people, but by the time he was a teenager, his odd habits—an inclination to blurt out non sequiturs, avoid eye contact, dismantle radios, and dig five-foot holes (and stick his younger brother, Augusten Burroughs, in them)—had earned him the label “social deviant.” It was not until he was forty that he was diagnosed with a form of autism called Asperger’s syndrome. That understanding transformed the way he saw himself—and the world. A born storyteller, Robison has written a moving, darkly funny memoir about a life that has taken him from developing exploding guitars for KISS to building a family of his own. It’s a strange, sly, indelible account—sometimes alien yet always deeply human.
Download or read book What Is a Person written by Christian Smith and published by University of Chicago Press. This book was released on 2010-09-15 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is a person? This fundamental question is a perennial concern of philosophers and theologians. But, Christian Smith here argues, it also lies at the center of the social scientist’s quest to interpret and explain social life. In this ambitious book, Smith presents a new model for social theory that does justice to the best of our humanistic visions of people, life, and society. Finding much current thinking on personhood to be confusing or misleading, Smith finds inspiration in critical realism and personalism. Drawing on these ideas, he constructs a theory of personhood that forges a middle path between the extremes of positivist science and relativism. Smith then builds on the work of Pierre Bourdieu, Anthony Giddens, and William Sewell to demonstrate the importance of personhood to our understanding of social structures. From there he broadens his scope to consider how we can know what is good in personal and social life and what sociology can tell us about human rights and dignity. Innovative, critical, and constructive, What Is a Person? offers an inspiring vision of a social science committed to pursuing causal explanations, interpretive understanding, and general knowledge in the service of truth and the moral good.
