PFOA and PFOS detected in newborns
An analysis of nearly 300 umbilical cord blood samples led by researchers at the Johns Hopkins Bloomberg School of Public Health shows that newborn babies are exposed to perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) while in the womb. PFOS and PFOA are polyfluoroalkyl compounds (PFCs)—ubiquitous man-made chemicals used in a variety of consumer products, including as a protective coating on food-contact packaging, textiles and carpets, and in the manufacturing of insecticides. The health impact from exposure to these compounds is not fully known, but previous studies found these compounds could cause tumors and developmental toxicity in laboratory animals at doses much higher than those observed in the Hopkins study.
Researcher dispels myth of dioxins and plastic water bottles
The Internet has been flooded with email warnings to avoid freezing water in plastic bottles so as not to get exposed to carcinogenic dioxins. One hoax email has been erroneously attributed to Johns Hopkins University since the spring of 2004. The Office of Communications and Public Affairs discussed the issue with Rolf Halden, PhD, PE, assistant professor in the Department of Environmental Health Sciences and the Center for Water and Health at the Johns Hopkins Bloomberg School of Public Health. Dr. Halden received his masters and doctoral degrees researching dioxin contamination in the environment. We sat down with him to set the record straight on dioxins in the food supply and the risks associated with drinking water from plastic bottles and cooking with plastics. more
Key found to kill cystic fibrosis superbug
Researchers from the Schulich School of Medicine & Dentistry at The University of Western Ontario , working with a group from Edinburgh, have discovered a way to kill the cystic fibrosis superbug, Burkholderia cenocepacia. These investigators, under the leadership of Dr. Miguel Valvano, Department of Microbiology and Immunology, have had their research published in the May issue of the Journal of Bacteriology, and highlighted in Nature Reviews/Microbiology. more
Corn, oats, cherries and red wine’s high melatonin content can help delay ageing
A study carried out by researchers from the University of Granada’s Institute of Biotechnology proves that consuming melatonin neutralizes oxidative damage and delays the neurodegenerative process of ageing. - In this study researchers used normal and genetically-modified mice which were subjected to accelerated cell ageing, although their results can also be applied to humans. more
Antioxidant found in many foods and red wine is potent and selective killer of leukemia cells
A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine. These findings, which were published online March 20 in the Journal of Biological Chemistry and will be in press on May 4, offer hope for a more selective, less toxic therapy for leukemia.
UCLA study finds prostate cancer treatments impact on quality of life
A rigorous, long-term study of quality of life in patients who underwent one of the three most common treatments for prostate cancer found that each affected men's lives in different ways. The findings provide invaluable information for men with prostate cancer who are facing vital treatment decisions. more
HIV infection appears to increases the risk of heart attack
Researchers from Massachusetts General Hospital (MGH) have found that infection with HIV, the virus that causes AIDS, is also associated with increased risk of myocardial infarction or heart attack. While rates of several cardiovascular risk factors were also increased in study participants infected with HIV, the increased incidence of heart attack was beyond what could be explained by risk factor differences. The report will be published in the Journal of Clinical Endocrinology and Metabolism and has been released online. more
