Doping Agency Bans Xenon And Argon

 10 years ago your competent? doctor SHOULD HAVE  IMMEDIATELY STARTED ADMINISTERING THESE GASES TO STROKE SURVIVORS TO SAVE DYING NEURONS! Since they didn't, they all need to be fired and stripped of their licenses! I take no prisoners in trying to get stroke solved. Get in the way and 10 million yearly stroke survivors will run you over suing you for medical malpractice!

Send me hate mail on this: oc1dean@gmail.com. I'll print your complete statement with your name and my response in my blog. Or are you afraid to engage with my stroke-addled mind? No excuses are allowed! You're medically trained; it should be simple to precisely refute all my points with NO EXCUSES!! And what is your definition of competence in stroke? Swearing at me is allowed, I'll return the favor.

Doping Agency Bans Xenon And Argon 

      Sports: Athletes have been using noble gases to boost oxygen-carrying capacity of blood

The World Anti-Doping Agency, which governs international drug testing for competitive athletes, will add the noble gases xenon and argon to its List of Prohibited Substances & Methods effective Sept. 1.

It’s hard to imagine how the essentially chemically inert gaseous elements could improve athletic performance. But xenon is surprisingly bioactive and can enhance the oxygen-carrying capacity of blood. Argon is thought to work the same way.

Xenon is known to interact with protein receptors and ion channels and function as a hypoxia-inducible factor (HIF), similar to nitrous oxide (laughing gas). As such, xenon has been used as an anesthetic for decades, notably in Russia.

When it comes to improving athletic performance, xenon is one of several agents known to activate production of HIF-1α, a protein alarm that triggers other proteins to come to the rescue of tissues deprived of oxygen. One of those secondary proteins is erythropoietin (EPO), a hormone that encourages the formation of red blood cells. Synthetic EPO is used for treating anemia in patients with cancer and kidney disease, but it is infamous as a banned performance-enhancing drug, especially among endurance athletes such as cyclists.

Athletes have turned to inhaling xenon in the same way they might train in low-oxygen conditions at high altitude. Xenon and argon clear from the body within hours, but the performance-enhancing effects can last several days. The agency did not announce how it would test for xenon or argon doping, which may be hard to detect beyond measuring variable HIF-1α or EPO levels.
