If your meat needs to be plumped up, try some collagen injections.
Injecting meatballs with collagen can help the meat to retain the important nutrients iodine and thiamine, a new study by researchers from the Agricultural University of Poznan in Poland shows.
We all know that eating fruits, vegetables and soy products provides essential nutrition for a healthy lifestyle, while obesity leads to the opposite. Yet proving the effect of nutrition, or obesity, on cancer is an experimental challenge and a focus for scientists. According to emerging evidence, eating well might still be one of the more pleasurable ways to prevent cancer and promote good health.
Abstract 4217: A novel mechanism for the chemoprotection by 3,3-diindolylmethane (DIM) and genistein for breast and ovarian cancer.
Researchers at Columbia University’s Mailman School of Public Health have discovered a means for early detection of liver cancer. Using DNA isolated from serum samples as a baseline biomarker, the scientists examined changes in certain tumor suppressor genes that have been associated with the development of liver carcinomas. This is the first study to prospectively examine potential biomarkers for early detection of liver cancer in high-risk populations, including those with chronic hepatitis B and C virus infections.
In recent years, researchers have worked to develop a number of vaccines to help the immune system fight tumors. Cancer vaccines are not intended to prevent cancer; rather, they are used to boost immune responses to preexisting tumors. Unlike traditional chemotherapy, vaccines have relatively low toxicity and, potentially, a high degree of efficacy.
To date, these vaccines have rarely been designed to directly stimulate one of the body's most critical immune responders, the helper T cells. Though helper T cells contain receptors on their cell surfaces that are capable of recognizing and binding to tumor-related antigens, scientists have been stymied by the complex and time-consuming process required to isolate and clone the antigens for vaccine development.
Polychlorinated diphenyl ethers (PBDEs), common in flame retardants, have shown steady increases in the environment. These compounds accumulate through the food chain, reaching high levels in top predators. A new study published in the latest issue of Environmental Toxicology and Chemistry provides the first evidence of the harmful effects of these contaminants to a mammalian top predator, the mink.
Dream journals being kept by students in a college psychology class have provided researchers with a unique look at how people experienced the events of 9/11, including the influence that television coverage of the World Trade Center attacks had on people’s levels of stress.
Reported in the April 2007 issue of the journal Psychological Science, the study data finds that for every hour of television viewed on Sept. 11 – with some students reporting in excess of 13 hours watched – levels of stress, as indicated by dream content, increased significantly. In addition, the study found that time spent talking with family and friends helped individuals to better process the day’s horrific events.
