Could outdoor light exposure at night heighten breast cancer risk?

JOURNAL-Environmental Health Perspectives

High exposure to outdoor lighting at night time may be a risk factor for breast cancer development, a new study suggests.

From an analysis of almost 110,000 women, researchers found that those who resided in areas with high levels of outdoor light at night time were more likely to develop breast cancer compared with women who lived in areas with low levels of outdoor light during the night.

Lead study author Peter James, of the Harvard Pilgrim Health Care Institute at Harvard Medical School in Boson, MA, and colleagues published their findings in the journal Environmental Health Perspectives

Using mushrooms as a prebiotic may help improve glucose regulation

August 16, 2018 Penn State Eating white button mushrooms can create subtle shifts in the microbial community in the gut, which could improve the regulation of glucose in the liver, according to a team of researchers. They also suggest that better understanding this connection between mushrooms and gut microbes in mice could one day pave the way for new diabetes treatments and prevention strategies for people.

Green tea ingredient may ameliorate memory impairment, brain insulin resistance, and obesity

Federation of American Societies for Experimental Biology A study published online in The FASEB Journal, involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment. Previous research pointed to the potential of EGCG to treat a variety of human diseases, yet until now, EGCG's impact on insulin resistance and cognitive deficits triggered in the brain by a Western diet remained unclear. Journal Reference: Yashi Mi, Guoyuan Qi, Rong Fan, Qinglian Qiao, Yali Sun, Yuqi Gao, Xuebo Liu. EGCG ameliorates high-fat– and high-fructose–induced cognitive defects by regulating the IRS/AKT and ERK/CREB/BDNF. The FASEB Journal, 2017; fj.201700400RR DOI: 10.1096/fj.201700400RR

WHY DOES HAIR TURN GRAY?

Some people think, growing hair gray distinguish them from others.Some people think they are getting old. However scientists have tried to find an answer so many years.Finally they have come up with a theory. Hair gets its color from a pigment called melanin, which is produced by melanocyte cells in the hair follicles. Researchers have discovered that melanocytes endure cumulative damage over the years, which eventually leaves them unable to produce melanin. Studies have cited DNA damage and a buildup of hydrogen peroxide in the follicles as possible causes of this disruption in melanin production. Without melanin, the new hair that grows in has no pigment, which makes it appear gray, white, or silver. Some people start to go gray young. All most all the things in the body are usually determined by genes.This incident also determined by the genes.If your mother or father has started to go gray early their lives, You also have a chance to go gray early.However you...
