Researchers have discovered how unusually long pieces of RNA work in skin cells. The RNA pieces, called 'long non-coding RNAs' or 'lncRNAs,' help skin cells modulate connective tissue proteins, like collagen, and could represent novel therapeutic targets to promote skin repair.
People who often sunbathe or use tanning beds are more likely to try risky weight-loss methods and have cosmetic surgery, as well as get tattoos and piercings. But while people who seldom tan also may try unsafe diets and cosmetic surgery, they rarely opt for tattoos or piercings, according to a new study.
In article, a study performed by a group of researchers elucidates action mechanism of visible light on skin and questions typical use of sunscreen. Most common sunscreens affect D vitamin absorption and fail to block visible light -- which, while not as damaging as UV rays, accounts for 45 percent of the solar radiation. The group patented skin-colored sunscreen which can block visible light.
UV radiation has been known for a long time to be a risk factor for the development of skin cancer. Simultaneous infection with human papillomaviruses (HPV) has also been suspected to promote skin cancer, particularly in organ transplant recipients. Scientists have now been able to show for the first time in a natural system that papillomaviruses associated with UV light promote the development of non-melanoma skin cancer.
