U.S. scientists have found an effective chemical molecules to deal with skin sunburn

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.

6 signs that you need a healthier lifestyle

Body load is too large, even when there is no obvious exhaustion and psychological phenomena such as the collapse of our body and brain will send a variety of signals, suggesting that “really had enough." Recently, the United States, “Oprah Life Network” contains text; you summed up the “body beyond the limits of six signals." Here is more information about health news and events.

1. Nap while also dreaming. Nap can give the body to "recharge." However, Virginia Massa Jefferson Hospital Sleep Medicine Research Center Director Christopher Dr Venter said that a nap for a maximum of 30 minutes or so, usually only in a light sleep state. But if you take a nap when an eyes closed, they begin to do all sorts of strange dream, suggests that the brain a serious lack of sleep, can not wait to enter the deep sleep phase.

2. Memory deteriorated. Columbia University, anxiety and related disorders clinic director Anne Marie Albano said that some healthy people a bad memory. In fact, these people are "brain overload", hormonal changes disrupt the memory function, people can not remember more content, easy to forget recent.

3. Even worse after exercise. American professor of obstetrics and gynecology at Wake Forest University School of Medicine, said Dr Sarah Gulbarga, under normal circumstances, jogging 45 minutes will make people feel very relaxed, but if you're just starting to feel tired movement, it shows the body has been overloaded. Gulbarga doctoral research found that women who were moderate stress intensity exercise, the body will be insufficient supply of energy, feeling tired, and fatigue.

4. Coffee will be trapped. American clinical psychologist Dr. Michael Bristol, drinking coffee descendants of brain activity will change. If caffeine did not work, it means that extreme physical and mental fatigue has been offset by caffeine stimulant.

5. Eat mild foods can also aggravate heartburn. “Psychosomatic Medicine Research" published a study that confirmed that stress does not cause heartburn. Even without eating spicy foods, pantothenic acid, or more severe symptoms persist, it shows too much pressure.

6. Scalp becomes sensitive. Pennsylvania clinical psychologist Dr. Richard Fred pressure usually causes skin neuropeptides and other natural chemicals increased, causing inflammation. This inflammation will be the outbreak of acne or rosacea and other forms, and some will lead to vasoconstriction, so that the skin of the face and head too tight, tingling or sensitive.
