Recently, American scientists succeeded in finding a chemical molecules called TRPV4, its role is overexposure to ultraviolet light generated by itching, redness, peeling sunburn symptoms produced a series of crucial influence. To offer the chemical molecules secreted inhibitor added to sunscreen creams, allowing ultraviolet rays of the sun in the confrontation can produce a more effective role.
China Network August 12 hearing, according to the French " Le Figaro" website reported on August 11, U.S. researchers recently announced that it has succeeded in finding a more effective inhibition of sunburn and reduce skin damage chemical molecules. More news on skin care.
Recently, the United States three universities - Duke University, Rockefeller University and the University of California, San Francisco (UCSF) joint participation in a study called TRPV4 successfully found a chemical molecules, whose role is overexposure to ultraviolet light produced by itching, redness, peeling sunburn symptoms produced a series of crucial influence.
Because the body can produce vitamin D light elements, it is appropriate to ultraviolet radiation in daily life is still very necessary. However, once the excessive human exposure to the sun, it will result in a short period of redness, peeling and other symptoms of sunburn, and thus leaving the skin is aging rapidly and increase the chances of skin cancer prevalence.
Recently, one published in the "American National Academy of Sciences " (PNAS) the study showed, by the excessive ultraviolet radiation generated by sunburn symptoms may be one element in and out. Research team leader, Duke University School of Medicine professor of neurology and neurobiology Wolfgang Liedtke explained: "We found that for sunburn symptoms of a new interpretation of the doctrine."
In this experiment, the researchers will feature a group of normal mice and another group after transgene can not secrete chemical molecules TRPV4 rats were placed in UV light, after some time found that the measure has not been genetically modified, continue to secrete TRPV4 chemical molecules against excessive ultraviolet radiation group rats produced a fur blisters, peeling sunburn, allergic reactions, but not transgene chemical molecules secreted TRPV4 fur group rats were relatively no strong allergic reactions.
To further demonstrate the effect of chemical molecules TRPV4 research team rat skin cells was related experiments, subsequently on human skin cells to the same experiment. Study found that prolonged exposure to UV light activates TRPV4 chemical molecules, so that calcium ions confluence trigger spread, causing pain, inflammation, itching coexist appear, and then will lead to the proliferation of chemical molecules in vivo TRPV4 increased, and so on ad infinitum, causing the skin surface adverse reactions.
With this discovery, the researchers attempt to normal non-transgenic mice implanted chemical molecules secreted elements TRPV4 inhibition experiments. The results showed that: inhibitor prevents the confluence of calcium in cells, it eliminates the effects of ultraviolet radiation on the skin irritation.

Xbox One and Windows Phone system share video store
Along with Microsoft's next-gen consoles Xbox One of the officially listed, Windows Phone system also began to slowly benefit. Today Microsoft announced, WP phones will soon be able to download and play from the Xbox video store TV shows and movies, but also will be able to use the Microsoft Money (i.e. previous Microsoft Points) on Windows Phone store to consume.
At the same time, users will be able to play in the WP phone more compatible to the Xbox Live " three screen" games such as "Call of Duty: The Phantom " is also introduced the Windows Phone version.
Microsoft Windows applications and games Bray Head Todd Brix said: "We have made some of the three-screen games, " Shogun skull " is one of a. Players can then put the phone functions through the Smart Glass become Xbox One side of ' mirror ', then use Photo beamer photo sharing feature to the game on any device. "
Prior to Windows Phone, Xbox has been interrelated: both can use the same Microsoft account login, Windows Phone support for the Xbox Live Avatar replacement and modification information. But let mobile phone users can control the second screen Smart Glass features not just exclusively by the Windows Phone, it also can be used on iOS and Android systems.
Xbox video store will soon be able to solve the Windows Phone system longstanding video download difficulty. While on the phone already had Netflix WP such video applications, but has been unable to download those using the DRM (Digital Rights encryption) technology for video, and this downloading function in iOS, Android and Blackberry systems already implemented.
Microsoft's new Windows Phone payment system will also bring benefits. Under the new regulations, the user's account balance can also be used on Windows Phone. Microsoft paid in cash and the issuance of reward system instead of the original point system, so players can get through Xbox Live Rewars cash balance to get Windows Phone store to purchase applications and games. Obviously one U.S. dollar can not buy Xbox One game, but you can buy exquisite mobile applications.
