Blood Test Accurately Detects Stage 1 Lung & Breast Cancers

Taking less than an hour, a simple blood test developed by Kansas State University (Kansas, USA) is able to accurately detect breast cancer and non-small cell lung cancers before symptoms manifest.  Stefan Bossmann and colleagues devised a technology that detects increased enzyme activity in the body.  Iron nanoparticles coated with amino acids and a dye are introduced to small amounts of blood or urine from a patient. The amino acids and dye interact with enzymes in the patient's urine or blood sample. Each type of cancer produces a specific enzyme pattern, or signature, that can be identified by doctors. Once the test is administered, comprehensive results -- which include enzyme patterns -- are produced in roughly 60 minutes.  The team has also designed a second testing method that is anticipated to produce the same results in about five minutes. Also, the team anticipates adding the capacity to test for the early stages of pancreatic cancer shortly

55. Be Travel Wise, Not Travel Weary
In a single year, an estimated 1.5 billion people travel by commercial airplane. So, it's not too difficult to imagine how easy it could be to become sick while in an airport or aboard an aircraft. To keep the skies friendly to your health, consider following these ten travel-savvy tips:
1. Wear loose clothing. If you feel bloated after disembarking from a plane, it’s because the low air pressure (8000 feet [2,438 meters] inside the jet cabin) makes our bodies swell up.
2. Keep your fluids up. While in flight, drink 8 ounces (236 ml) of water during every hour. Cabin air is notoriously dry (0 to 2% humidity). Be sure to take the flight attendants up on their offers of bottled water during your flight. Avoid tap water on airplanes. It is treated with mild detergents, and no regulatory standards are in effect for commercial aircraft water tanks
