Skin Pigmentation News and Research

RSS

The color of the human skin is due to a brown pigment called melanin. Pigmentation or coloration of the skin is dependent on the amount of melanin present in the skin. People with pale skin produce very little melanin and people with darker skin produce higher amounts of melanin. Pregnancy and sun exposure can also make skin darker, while infections, burns, and blisters can make skin lighter.

Vitamin D deficiency could lead to heart problems

Vitamin D deficiency - which is traditionally associated with bone and muscle weakness - may also increase the risk of cardiovascular disease (CVD).

No doubt: sun causes melanomas

A leading University of Sydney researcher writes in the prestigious British Medical Journal today that claims that the sun is not the key cause of melanomas are false.

New, single-exposure imaging tool puts biomedical imaging in palm of hands

Researchers at Georgia Tech have developed a narrowband filter mosaic that will expand the uses and functionality of multispectral imaging-a technology that enables subsurface characterization.

Study shows effects of vitamin D and skin's physiology

Researchers from Boston University School of Medicine (BUSM) have found that previtamin D3 production varies depending on several factors including skin type and weather conditions.

Cosmecueticals improve skin

Cosmecueticals, beauty aids that reportedly work like prescription drugs, are providing new ways to treat aging skin.

Same genetic machinery generates skin color evolution in fish and humans

When humans began to migrate out of Africa about 100,000 years ago, their skin color gradually changed to adapt to their new environments.

Genetic evidence that human evolution is speeding up

Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different.

Clear link between lack of sunlight and endometrial cancer

Using newly available data on worldwide cancer incidence, researchers at the Moores Cancer Center at University of California, San Diego (UCSD) have shown a clear association between deficiency in exposure to sunlight, specifically ultraviolet B (UVB), and endometrial cancer.

Exposure to sunlight may decrease risk of advanced breast cancer

A research team from the Northern California Cancer Center, the University of Southern California, and Wake Forest University School of Medicine has found that increased exposure to sunlight - which increases levels of vitamin D in the body - may decrease the risk of advanced breast cancer.

Sunlight may decrease risk of advanced breast cancer

A research team from the Northern California Cancer Center, the University of Southern California, and Wake Forest University School of Medicine has found that increased exposure to sunlight – which increases levels of vitamin D in the body -- may decrease the risk of advanced breast cancer.

New options in treating pigmentation disorders

Melanocytes are not the only cells responsible for differences in skin coloration. New research from the University of Cincinnati (UC) has shown that some of the most basic cells on the skin's surface influence pigment production and help regulate skin coloration.

New evidence of very recent human adaptation

A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa.

Vitamin D deficient rickets in infants

The message about preventing vitamin D deficient rickets in children is not getting through, warn senior doctors in this week's BMJ.

Avicena issued U.S. creatine patent

Avicena Group has announced that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 7,186,754, entitled, "Use of Creatine or Creatine Compounds for Skin Preservation," on March 6, 2007.

Gene that prevents cancer also controls the skin's suntanning machinery

"The p53 tumor suppressor is commonly mutated in human cancer," explained David Fisher, director of the Melanoma Program in Medical Oncology at Dana-Farber Cancer Institute. "Now, we've found that it plays a role in the skin's tanning response."

Vitamin D supplements should be given to Asian children from birth up to the age of two years

Vitamin D deficiency can cause rickets, poor tooth formation, convulsions, general ill health, and stunted growth. And it has been linked to an increased risk of multiple sclerosis, certain cancers, and cardiovascular disease, diabetes, osteoporosis, and mental health problems in later life.

Study of predictors of vitamin D status and cancer incidence and mortality in men

Low levels of vitamin D may be associated with increased total cancer incidence and mortality in men, particularly for cancers of the digestive system, according to a study in the Journal of the National Cancer Institute.

A map of recent positive selection in the human genome

By scanning the entire human genome in search of genetic variations that may signal recent evolution, University of Chicago researchers found more than 700 genetic variants that may be targets of recent natural positive selection during the past 10,000 years of human evolution.
