10/12/2013 0 Comments Breaking News: A*Star scientists may have found a way to drive cancer cells to "suicide"Published on Oct 07, 2013 By Grace Chua
Scientists have found that the difference between life and death for some cancer cells hinges on a tiny molecular change - which could one day be harnessed to drive cancer cells to suicide. Researchers from Oxford University, the University of Texas, and the Genome Institute of Singapore (GIS) at the Agency for Science, Technology and Research (A*Star), found that E2F, a protein which helps control cell growth, can be affected by a process called methylation, where a cluster of carbon and hydrogen atoms latches on to the outside of a gene and makes it harder or easier for that gene to be active. Depending on where E2F is methylated, it can either cause cells to die off or to proliferate, with what researchers termed "an exquisite level of precision". Professor Nick La Thangue of the department of oncology at Oxford University, who supervised the project explained: "It's like there's an angel and a devil competing to get on each shoulder of the protein. Which one gets the upper hand is able to whisper in the ear of the protein and tell it what it should do. With the molecular flag on one shoulder, E2F goes into cell kill mode. With the flag on the other, it goes into cell growth mode." Source

Heart attack coming on? Yep, you guessed it: There’s an app for that.
A new medical device could turn your phone into a lifesaver; the tiny implant monitors your blood and can send a warning to your smartphone if it detects potentially life-saving problems. The device, developed by a team of scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland is the world’s smallest such implement ever; using Bluetooth, it transmits data to your phone and could even warn you if you’re about to have a heart attack. Since many people are alone when they suffer a heart attack, without help,the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
However,these victims can help themselves by coughing repeatedly and very vigorously. A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest. A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again. Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can get to a hospital. Tell as many other people as possible about this. It could save their lives!! A cardiologist says If everyone who sees this post shares it to 10 people, you can bet that we'll save at least one life.. Rather than sharing jokes only please contribute by forwarding this info which can save a person's life.. |
