It is the first biomaterials book written by selected academic and clinical experts experts on biomaterials and medical devices from various institutions and industries in Indonesia. It serves as a reference source for researchers starting new projects, for companies developing and marketing products and for governments setting new policies. Chapter one covers the fundamentals of biomaterials, types of biomaterials, their structures and properties and the relationship between them. Chapter two discusses unconventional processing of biomaterials including nano-hybrid organic-inorganic biomaterials. Chapter three addresses biocompatibility issues including in vitro cytotoxicity, genotoxicity, in vitro cell models, biocompatibility data and its related failure. Chapter four describes degradable biomaterial for medical implants, which include biodegradable polymers, biodegradable metals, degradation assessment techniques and future directions. Chapter five focuses on animal models for biomaterial research, ethics, care and use, implantation study and monitoring and studies on medical implants in animals in Indonesia. Chapter six covers biomimetic bioceramics, natural-based biocomposites and the latest research on natural-based biomaterials in Indonesia. Chapter seven describes recent advances in natural biomaterial from human and animal tissue, its processing and applications. Chapter eight discusses orthopedic applications of biomaterials focusing on most common problems in Indonesia, and surgical intervention and implants. Chapter nine describes biomaterials in dentistry and their development in Indonesia.
An exposé on Big Pharma and the American healthcare system’s zeal for excessive medical testing, from a nationally recognized expert More screening doesn’t lead to better health—but can turn healthy people into patients. Going against the conventional wisdom reinforced by the medical establishment and Big Pharma that more screening is the best preventative medicine, Dr. Gilbert Welch builds a compelling counterargument that what we need are fewer, not more, diagnoses. Documenting the excesses of American medical practice that labels far too many of us as sick, Welch examines the social, ethical, and economic ramifications of a health-care system that unnecessarily diagnoses and treats patients, most of whom will not benefit from treatment, might be harmed by it, and would arguably be better off without screening. Drawing on 25 years of medical practice and research on the effects of medical testing, Welch explains in a straightforward, jargon-free style how the cutoffs for treating a person with “abnormal” test results have been drastically lowered just when technological advances have allowed us to see more and more “abnormalities,” many of which will pose fewer health complications than the procedures that ostensibly cure them. Citing studies that show that 10% of 2,000 healthy people were found to have had silent strokes, and that well over half of men over age sixty have traces of prostate cancer but no impairment, Welch reveals overdiagnosis to be rampant for numerous conditions and diseases, including diabetes, high cholesterol, osteoporosis, gallstones, abdominal aortic aneuryisms, blood clots, as well as skin, prostate, breast, and lung cancers. With genetic and prenatal screening now common, patients are being diagnosed not with disease but with “pre-disease” or for being at “high risk” of developing disease. Revealing the economic and medical forces that contribute to overdiagnosis, Welch makes a reasoned call for change that would save us from countless unneeded surgeries, excessive worry, and exorbitant costs, all while maintaining a balanced view of both the potential benefits and harms of diagnosis. Drawing on data, clinical studies, and anecdotes from his own practice, Welch builds a solid, accessible case against the belief that more screening always improves health care.
For the twenty three years prior to its banning on June 21 1994, Tempo magazine was Indonesia's most important news weekly, and its editor in chief one of Indonesias's leading poets and intellectuals. This book tells the story of the paper, its staff and many supporters, and of its relations with political movements.
"This landmark publication in comparative linguistics is the first comprehensive work to address the general issue of what kinds of words tend to be borrowed from other languages. The authors have assembled a unique database of over 70,000 words from 40 languages from around the world, 18,000 of which are loanwords. This database allows the authors to make empirically founded generalizations about general tendencies of word exchange among languages." --Book Jacket.
With the fascinating scholarship of The Emperor of All Maladies and the deeply personal experience of When Breath Becomes Air, a world-class oncologist examines the current state of cancer and its devastating impact on the individuals it affects -- including herself. In The First Cell, Azra Raza offers a searing account of how both medicine and our society (mis)treats cancer, how we can do better, and why we must. A lyrical journey from hope to despair and back again, The First Cell explores cancer from every angle: medical, scientific, cultural, and personal. Indeed, Raza describes how she bore the terrible burden of being her own husband's oncologist as he succumbed to leukemia. Like When Breath Becomes Air, The First Cell is no ordinary book of medicine, but a book of wisdom and grace by an author who has devoted her life to making the unbearable easier to bear.
The Carotenoids book series provides an introduction to the fundamental chemistry, detailed accounts of the basic methods used in carotenoid research, and critical discussions of the biochemistry, functions and applications of carotenoids. Part 1 discusses the fundamental properties on which the biological functions and effects of carotenoids depend. Part 2 describes important natural functions of carotenoids in all kinds of living organisms.
War is a fact of human nature. As long as we exist, it exists. That's how the argument goes. But longtime Scientific American writer John Horgan disagrees. Applying the scientific method to war leads Horgan to a radical conclusion: biologically speaking, we are just as likely to be peaceful as violent. War is not preordained, and furthermore, it should be thought of as a solvable, scientific problem—like curing cancer. But war and cancer differ in at least one crucial way: whereas cancer is a stubborn aspect of nature, war is our creation. It’s our choice whether to unmake it or not. In this compact, methodical treatise, Horgan examines dozens of examples and counterexamples—discussing chimpanzees and bonobos, warring and peaceful indigenous people, the World War I and Vietnam, Margaret Mead and General Sherman—as he finds his way to war’s complicated origins. Horgan argues for a far-reaching paradigm shift with profound implications for policy students, ethicists, military men and women, teachers, philosophers, or really, any engaged citizen.
