The stem cells are derived from material left over from open-heart operations. Researchers at UMC Utrecht used a simple method to isolate the stem cells from this material and reproduce them in the laboratory, which they then allowed to develop. The cells grew into fully developed heart muscle cells that ...
Inflammation is the body’s response to injury in tissues, prompting healing that leads to scars, whether on the skin, or in organs such as the heart, liver or lungs. Such scarring has beneficial properties, but there’s also the risk of excessive scarring, or tissue fibrosis, that can lead to ...
An additional 10 percent of women report symptoms consistent with eating disorders such as anorexia, bulimia nervosa and binge eating disorder, meaning that a total of 75 percent of American women surveyed endorse some unhealthy thoughts, feelings or behaviors related to food or their bodies. “Our survey found that these behaviors ...
Life expectancy of a significant segment of the U.S. population is declining or at best stagnating, researchers have found. (Credit: iStockphoto/Jan van den Brink) Now, a new, long-term study of mortality trends in U.S. counties over the same four decades reports a troubling finding: ...

Stromal stem cells - cells that are present in connective tissues - have recently been identified in endometrial tissues of the uterus. When the fresh growth of tissue and blood vessels is shed during each menstrual cycle, some cells with regenerative capabilities are present and collectable. While collecting menstrual blood ...
Gastric cancer is the second most common cause of cancer-related deaths around the world, and has been shown previously to be correlated with chronic inflammation. Persistent activation of the Stat3 protein, which is known to play roles in inflammation-associated carcinogenesis, is commonly found in gastric and many other types ...
This step -- the creation of new blood vessels -- enables tumors to grow out of control and ultimately spread cancer to other parts of the body. Targeting blood vessel formation, or angiogenesis, promises to be less toxic than the standard chemotherapy approach that kills cancer cells and normal cells alike. ...
Researchers worldwide are working to understand how certain kinds of proteins, called prions, cause degenerative brain diseases such as CAA. More common prion diseases include bovine spongiform encephalopathy (mad cow disease), and Creutzfeldt-Jakob disease in humans. All are incurable and fatal. Ohio State University chemist Christopher Jaroniec and his colleagues ...
The team’s findings are the latest in a long and distinguished line of research at CSHL involving adenovirus, a type of virus that causes the common cold in people, but whose genome contains known oncogenes -- genes whose expression can promote cancer under certain conditions. “Adenovirus carries a number of cooperating ...
