...definition we use is when the heart stops beating, the lungs stop working, and as a consequence the brain itself stops working. When doctors shine a light into someone's pupil, it's to demonstrate that there is no reflex present. The eye reflex is mediated by the brain stem, and that's the area that keeps us alive; if that doesn't work, then that means that the brain itself isn't working. At that point, I'll call a nurse into the room so I can certify that this patient is dead. Fifty years ago, people couldn...
...more than 20 years - certainly would indicate that warming will only make things worse. So, what can be done to help millions of sneezing, watery-eyed patients? As allergy sufferers already know, not a whole lot. But any action taken to control rising CO2 levels might at least help stem the increase in global allergy rates. So far, the global asthma epidemic shows no signs of abating, and in a warmer world, effective treatments for allergies will likely become even more important. One option for allergy suffers might be to start agitating for action to reduce CO2 emissions - after...
...This has really been one of the goals of stem cell biology for many years—to be able to produce customized disease-specific lines for different patients,” said George Q. Daley, a member of the executive committee of HSCI and the senior author of the paper, which was published on the Web site of the journal Cell...
...After three years of endless experiments on mouse cells, scientists at the Harvard Stem Cell Institute have discovered the three transcription factors out of a possible 1,100 that may provide the key to unlocking the secret to growing replacement tissues—a longtime goal of regenerative medicine...
...Despite the relative efficiency of this approach, both Melton and Daley stressed that direct reprogramming does not eliminate the need to continue work with iPS cells or human embryonic stem cells. Melton explained that it is simply another way of approaching the same problem scientists face in regenerative medicine—how to make cells to replace lost or deficient ones...
