ADA releases updated position paper on nutrient supplementation

While supplements can help some people meet their nutrition needs, eating a wide variety of nutrient-rich foods is the best way for most people to obtain the nutrients they need to be healthy and reduce their risk of chronic disease, according to a newly updated position paper titled "Nutrient Supplementation" from the American Dietetic...

Berkeley Lab experts assist in the greening of China

Lawrence Berkeley National Laboratory scientists Lynn Price and Nan Zhou expected the long banquet and endless toasting. What they did not expect on a recent trip to a cement plant in central China was a three-hour variety show by the factory employees, complete with folk dancing, song-and-dance numbers and comedians. Even more surprising were the lyrics to one of the songs: "I started to listen...

Bone marrow cells may significantly reduce risk of second heart attack

After heart attack patients' arteries were cleared by reperfusion, progenitor cells, derived from the patients' own bone marrow, were infused into that artery. This reduced the risk of death or another heart attack. The finding also holds promise that bone marrow progenitor cells can reduce debilitating or fatal heart failure in heart attack survivors. Larger trials are needed to confirm the...

Gene therapy and stem cells save limb

Blood vessel blockage, a common condition in old age or diabetes, leads to low blood flow and results in low oxygen, which can kill cells and tissues. Such blockages can require amputation resulting in loss of limbs. Now, using mice as their model, researchers have developed therapies that increase blood flow, improve movement and decrease tissue death and the need for...

Hidden sensory system discovered in the skin

Researchers report that the human body has an entirely unique and separate sensory system aside from the nerves that give most of us the ability to touch and feel. Surprisingly, this sensory network is located throughout our blood vessels and sweat glands, and is for most people, largely imperceptible. This discovery may shed light on the causes of unexplained chronic pain conditions such as...

New approach to treat lower back pain unveiled

Using a branch of science that crosses disciplines to study complex problems, a researcher is introducing a new way to understand and treat lower back pain, a condition affecting more than 40 million Americans and costing billions of dollars each year.

Possible ovarian cancer treatment target identified

A multi-institutional study has identified a potential personalized treatment target for the most common form of ovarian cancer. The research team discovered that a gene called MAGP2 -- not previously associated with any type of cancer -- was overexpressed in papillary serous ovarian tumors of patients who died more quickly. They also found evidence suggesting possible mechanisms by which MAGP2...

Psychological impacts not found for casual sex among young adults

Researchers have found that young adults engaging in casual sexual encounters do not appear to be at increased risk for harmful psychological outcomes as compared to sexually active young adults in more committed relationships. While this study focused on the psychological impact, researchers caution that the physical risks of casual sex should not be...
