...and possible uses, ethical issues and the state of research. By Mayo Clinic staff You've heard about stem cells in the news, and perhaps you've wondered if they might help you or a loved one with a serious disease. You may wonder what stem cells are, how they're being used to treat disease and injury, and why they're the subject of such vigorous debate. Here are some answers to frequently asked questions about stem cells. Why is there such an interest in stem cells? Researchers hope stem cell studies can help to: * Increase understanding of how diseases occur. By watching stem cells mature into cells that eventually become bones, heart muscle, nerve cells, and other organs and tissue, researchers and doctors may better understand how a variety of diseases and conditions develop. * Generate healthy cells to replace diseased cells (regenerative medicine). Researchers hope they can train stem cells into becoming specific cells so that those specialized cells can be used to regenerate and repair diseased or damaged tissues in people. People who might benefit from stem cell therapies include those with spinal cord injuries, type 1 diabetes, Parkinson's disease, Alzheimer's disease, heart disease, stroke, rheumatoid arthritis, osteoarthritis and multiple sclerosis. Stem cells could also be grown to become new tissue for use in transplant medicine. * Test new drugs for safety and effectiveness. Before using new drugs in people, researchers could use stem cells to...

...Huntington's: The Anticipation that Kills After doing research on the effects of the disorder Huntington’s disease, it is easy to understand what a disease like Huntington’s will do to an individual way of life. Imagine being thirty years old with a good job, a loving spouse, maybe a couple of kids and an all-around pretty good life. Then imagine one day your boss writes you up and sends you home because he/she suspects you of being intoxicated. A person in this situation could, in months and years to come, learn from a simple blood test that he/she is the victim of a genetic disorder called Huntington’s disease. The ramifications of this illness are endless and affect not only the individual with the disorder but entire families and communities as well. At this time there is no cure or even any significantly effective treatment. However, as with many genetic disorders, research is being done in in this day in age that may promise to one day lead us to such treatment or cure. Huntington’s disease is a neurodegenerative or genetic disorder that affects muscle coordination and some cognitive functions, typically becoming noticeable in middle age. It is much more common in people of Western Europe descent than in those from Asia or Africa. The disease is caused by dominant mutation on either of the two copies of a specific gene, located on chromosome 4. The Huntington gene normally provides the genetic code for a protein that is also called Huntingtin. The mutation of the Huntingtin...

...MORE ADVANCE NOISE FOR QUIET “An intriguing and potentially lifealtering examination of the human psyche that is sure to benefit both introverts and extroverts alike.” —Kirkus Reviews (starred review) “Gentle is powerful … Solitude is socially productive … These important counterintuitive ideas are among the many reasons to take Quiet to a quiet corner and absorb its brilliant, thought-provoking message.” —ROSABETH MOSS KANTER, professor at Harvard Business School, author of Confidence and SuperCorp “An informative, well-researched book on the power of quietness and the 3/929 virtues of having a rich inner life. It dispels the myth that you have to be extroverted to be happy and successful.” —JUDITH ORLOFF, M.D., author of Emotional Freedom “In this engaging and beautifully written book, Susan Cain makes a powerful case for the wisdom of introspection. She also warns us ably about the downside to our culture’s noisiness, including all that it risks drowning out. Above the din, Susan’s own voice remains a compelling presence—thoughtful, generous, calm, and eloquent. Quiet deserves a very large readership.” —CHRISTOPHER LANE, author of Shyness: How Normal Behavior Became a Sickness 4/929 “Susan Cain’s quest to understand introversion, a beautifully wrought journey from the lab bench to the motivational speaker’s hall, offers convincing evidence for valuing substance over style, steak over sizzle, and qualities that are, in America, often derided. This book is brilliant...

...GRE Analytical Writing ISSUE Essay Topic - 1 "Important truths begin as outrageous, or at least uncomfortable, attacks upon the accepted wisdom of the time." GRE AWA Analytical Writing ISSUE Essay Sample Solution – 1 “The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth.” ― Niels Bohr[->0] This is a proven fact that truth is the initial stage of progress. However, it is also believed that truth always starts away from the traditions and conventions. Therefore, people consider truths as attacks upon their beliefs, which people are following from ages. Truth also means some new facts that are unknown to us. People do not want to deviate from the facts, which they have learnt from their ancestors, and it is true to say that shedding ones dogmas is often difficult. They feel that it is an attack on their wisdom. If we look at the history of the world, we will find many examples where truth has generated commotions in the society. Different people have different views about the existence of God, life after death and origin of earth etc. For example, people took a long time to accept that the earth is round. Religious leaders and clergymen opposed this idea as it was against what they were teaching. Similarly, when Polish astronomer, Copernicus discovered that the earth goes round the sun and not vice versa, he was opposed by churches for many years. In fact he and his supporters were...
