Quit-smoking drug Chantix effective in cocaine and alcohol addiction

Varenicline is unique among anti-addiction medications in the way it affects the brain. Like nicotine, varenicline activates a specific receptor for a neurotransmitter called acetylcholine, but it does so less intensely than the active ingredient of cigarettes does. The net effect is that the drug seems to help by both cutting cravings and making the formerly desired drug less pleasant — without making non-drug pleasures less intense. Alcohol works on the same chemical receptors in the brain as nicotine, and it may enhance the pleasurable effects of smoking.

The 'nutritional magic' behind soy's heart health benefits

Nutrition science has regarded soy as a superfood with many health benefits for decades. In fact, "25 grams of soy protein per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease," according to the FDA.

Scientists produce mathematical model of calcium activity within atrial heart cell

What we perceive as the beating of our heart is actually the co-ordinated action of more than a billion muscle cells. Most of the time, only the muscle cells from the larger heart chambers contract and relax. But when the heart needs to work harder it relies on back-up from the atrial muscle cells deep within the smaller chambers (atria) of the heart.

New UTA method shows promise against heart disease

University of Texas at Austin researchers have demonstrated a new and more effective method for regrowing blood vessels in the heart and limbs - a research advancement that could have major implications for how we treat heart disease, the leading cause of death in the Western world.

Scientists create first 3-D living tissue model of glioma

Brown University scientists have created the first three-dimensional living tissue model, complete with surrounding blood vessels, to analyze the effectiveness of therapeutics to combat brain tumors. The 3-D model gives medical researchers more and better information than Petri dish tissue cultures.

Thrombocytosis linked to severity of ovarian cancer

Highly elevated platelet levels fuel tumor growth and reduce the survival of ovarian cancer patients, an international team of researchers led by scientists at The University of Texas MD Anderson Cancer center reports in the New England Journal of Medicine.

UCSF stem cell study suggests novel strategy for heart attack

A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels - and avoid the risk of tissue rejection.

Cancer cell communication signals may contain pieces of RNA

Researchers have shown that the communication signals sent around the body by cancer cells, which are essential for the cancer to grow, may contain pieces of RNA - these substances, like DNA, are pieces of genetic code that can instruct cells, and ultimately the body, how to form. The same study also found early indications that these genetic instructions can be intercepted and modified by chemotherapy to help prevent cancer cells growing.

Ovarian cancer subtype may be susceptible to 'anti-angiogenic' drugs

Scientists at Dana-Farber Cancer Institute have identified a subtype of ovarian cancer able to build its own blood vessels, suggesting that such tumors might be especially susceptible to "anti-angiogenic" drugs that block blood vessel formation.

Human 'shock absorbers' discovered

An international team of scientists, led by the University of Sydney, has found the molecular structure in the body which functions as our “shock absorber”. The discovery of the previously unknown part of the molecule will be applied to the researchers’ work on designing improved versions of a human blood vessel and on repairing skin damage, including burns.

New skin fillers and laser technologies can correct signs of aging

As we age, our skin undergoes a number of changes affecting its texture, volume and appearance. Fortunately, dermatologists can use fillers or lasers to correct the most notable signs of aging and can recommend skin care products with added ingredients that can further repair damaged skin.

Three new targeted drugs can lead to fatal cancer complications

Treatment with three relatively new "targeted" cancer drugs has been linked to a slightly elevated chance of fatal side effects, according to a new analysis led by scientists at Dana-Farber Cancer Institute. They added that the risk remains low, but should be taken into account by physicians and patients.
