Dartmouth researchers have found that duration of ibuprofen use was associated with a reduced risk of bladder cancer in patients in northern New England, which has a high mortality rate of this disease. In a 2012 collaborative project with the National Cancer Institute, Margaret Karagas, PhD, co-director, Cancer Epidemiology & Chemoprevention program at Norris Cotton Cancer Center, and Professor of Community and Family Medicine at the Geisel School of Medicine at Dartmouth, and Richard Waddell, D.Sc, Research Assistant Professor of Medicine at the Geisel School of Medicine, looked for connections between ibuprofen use and bladder cancer.

Researchers at the Institute for Aging Research (IFAR) at Hebrew SeniorLife, an affiliate of Harvard Medical School (HMS), have published a study that shows no evidence of a link between calcium intake and coronary artery calcification, reassuring adults who take calcium supplements for bone health that the supplements do not appear to result in the development of calcification of blood vessels.

Mounting evidence shows ‘cannabinoids’ in marijuana slow cancer growth, inhibit formation of new blood cells that feed a tumor, and help manage pain, fatigue, nausea, and other side effects.

A study by researchers at Johns Hopkins Medicine shows that when overweight or obese people lose weight, whether through a low-carb or low-fat diet, they can have a significant reduction in inflammation throughout their body, as measured by three common markers for inflammation.

A Vanderbilt study examining the impact of the two most commonly prescribed oral diabetes medications on the risk for heart attack, stroke and death has found the drug metformin has benefits over sulfonylurea drugs. It was important to examine the cardiovascular impact of the more commonly used diabetes drugs after recent controversy surrounded another diabetes medication, rosiglitazone, because it was associated with an increased cardiac risk, said lead author, Christianne L. Roumie, M.D., MPH, assistant professor of Internal Medicine and Pediatrics. Smaller studies pointed to a potential advantage of taking the drug metformin but this study confirms this in a large population.

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Linköping University in Sweden are showing how bacteria control processes in human cells the same way.

If you look old, your heart may feel old, according to research presented at the American Heart Association's Scientific Sessions 2012.In a new study, those who had three to four aging signs - receding hairline at the temples, baldness at the head's crown, earlobe crease, or yellow fatty deposits around the eyelid (xanthelasmata) -- had a 57 percent increased risk for heart attack and a 39 percent increased risk for heart disease .

A single junk food meal -- composed mainly of saturated fat -- is detrimental to the health of the arteries, while no damage occurs after consuming a Mediterranean meal rich in good fats such as mono-and polyunsaturated fatty acids, according to researchers at the University of Montreal-affiliated ÉPIC Center of the Montreal Heart Institute. The Mediterranean meal may even have a positive effect on the arteries.

High-intensity interval training makes middle-aged people not only healthier but smarter, showed a Montreal Heart Institute (MHI) study led by Dr. Anil Nigam of the MHI and University of Montreal, in collaboration with the Montreal Geriatric University Institute.

While Omega-3 essential fatty acids -- found in foods like wild fish and grass-fed livestock -- are necessary for human body functioning, their effects on the working memory of healthy young adults have not been studied until now.

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie early pathological events in Alzheimer's.

It turns out the muscle cells on the outside of blood vessels have been wrongly accused for instigating lung disease. New research shows that while these muscle cells are responsible for constricting or dilating the blood vessels, they are not responsible for sensing the amount of oxygen that gets to the lungs. That message comes from the endothelial cells -- special cells that line the blood vessels -- along a "signalling pathway."
