People who have skin cancer may be less likely to develop Alzheimer's disease, according to new research published in the May 15, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. The link does not apply to melanoma, a less common but more aggressive type of skin cancer. http://medicalxpress.com/news/2013-05-skin-cancer-linked-alzheimer-disease.html Alzheimer's disease & dementia Wed, 15 May 2013 16:00:01 EST news287825399 (Medical Xpress)—Research carried out by Professor Barbara Pierscionek and a team of fellow vision experts suggests that the way proteins are distributed in the lens of the eye may cause its gradient to be stepped rather than smooth as previously thought. The finding could give a new insight into the way the eye grows and lead to major improvements in synthetic lenses used in surgery to treat patients who have developed cataracts. http://medicalxpress.com/news/2013-03-poised-major-advances-cataract-treatment.html Ophthalmology Fri, 01 Mar 2013 08:30:02 EST news281347098 Work-related stress is not linked to the development of colorectal, lung, breast or prostate cancers, a study published today in BMJ suggests. http://medicalxpress.com/news/2013-02-stress-cancer.html Cancer Thu, 07 Feb 2013 18:30:02 EST news279472501 A pair of University of Colorado Cancer Center studies published this month show that the milk thistle extract, silibinin, kills skin cells mutated by UVA radiation and protects against damage by UVB radiation – thus protecting against UV-induced skin cancer and photo-aging. http://medicalxpress.com/news/2013-01-silibinin-thistle-uv-induced-skin-cancer.html Cancer Wed, 30 Jan 2013 14:46:37 EST news278779478 (Medical Xpress)—The average skin cancer risk from sunbeds is more than double that of spending the same length of time in the Mediterranean midday summer sun – according to new research from the University of Dundee and published today in the British Journal of Dermatology. http://medicalxpress.com/news/2013-01-sunbed-skin-cancer-mediterranean-midday.html Cancer Thu, 17 Jan 2013 06:31:56 EST news277626686 Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer's disease, Amyotrophic Lateral Sclerosis and Parkinson's disease.

In an article receiving Advance Online Publication in Nature, Massachusetts General Hospital (MGH) Cutaneous Biology Research Center (CBRC)and Cancer Center researchers report finding that the type of skin pigment predominantly found in red-haired, fair-skinned individuals may itself contribute to the development of melanoma. http://medicalxpress.com/news/2012-10-unexpected-factor-contributes-melanoma-red-haired.html Cancer Wed, 31 Oct 2012 17:31:32 EST news270923473 A telephone survey of 4,851 individuals in Germany suggests the overall prevalence of sunbed use was nearly 40 percent for participants who had ever used one and 14.6 percent had used a tanning bed within the last 12 months, according to a study published Online First by Archives of Dermatology. http://medicalxpress.com/news/2012-10-characteristics-sunbed-users-tanning.html Health Mon, 15 Oct 2012 16:00:05 EST news269514512 (Medical Xpress)—Researchers in Stanford's Department of Materials Science and Engineering are using models derived in mechanical labs to look closer at how ultraviolet radiation changes the protective functions of human skin. http://medicalxpress.com/news/2012-10-surface-uv-effects-skin-mechanics.html Medical research Fri, 05 Oct 2012 12:37:50 EST news268659451 (HealthDay) -- As the United States bakes under the summer sun, dermatologists often warn of cancer risks posed by ultraviolet (UV) sunlight.

The protein structures additionally determined by these researchers will improve our understanding of how the body protects itself against skin cancer. These studies lay the foundations for the development of a new class of anti cancer agents.
