"Moving to a more continuous follow-up approach would have the tremendous advantages of enhancing patient safety, decreasing physician and nurse work load, and allowing health staff to focus on medical emergencies," urged Professor Angelo Auricchio, from the European Heart Rhythm Association (EHRA) and official spokesperson of the European Society of Cardiology (ESC), adding that such systems may have the additional advantage of being more cost effective for health care providers.

LA JOLLA, CA, June 19, 2009—Researchers at The Scripps Research Institute, the University of California, San Diego, and Ohio State University have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment. One folded form is active and the other is inactive, but the protein can easily morph from one state to another.
Boston, MA -- As President Obama prepares to sign a bill giving the Food and Drug Administration (FDA) oversight of the tobacco industry, a new study from Harvard School of Public Health (HSPH) researchers shows that tobacco manufacturers have continually changed the ingredients and the design of their cigarettes over time, even if those changes have exceeded acceptable product variance guidelines.
ROCHESTER, Minn. -- Two Mayo Clinic patients whose prostate cancer had been considered inoperable are now cancer free thanks in part to an experimental drug therapy that was used in combination with standardized hormone treatment and radiation therapy. The men were participating in a clinical trial of an immunotherapeutic agent called MDX-010 or ipilimumab. In these two cases, physicians say the approach initiated the death of a majority of cancer cells and caused the tumors to shrink dramatically, allowing surgery.
The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials.
Without the process of domestication, humans would still be hunters and gatherers, and modern civilization would look very different. Fortunately, for all of us who do not relish the thought of spending our days searching for nuts and berries, early civilizations successfully cultivated many species of animals and plants found in their surroundings. Current studies of the domestication of various species provide a fascinating glimpse into the past.
HOUSTON - Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access.
Reporting online at Nature Cell Biology this week, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center shows that BRIT1 connects with another protein complex to relax DNA's tight packaging at the site of the damage.
German children are taller than 30 years ago, but the increase in height observed during the last century has become slower. In the current edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106(23): 377-82), Bettina Gohlke and Joachim Woelfle of the Department of Pediatrics at the University of Bonn summarize the current state of knowledge of changes in height and of the physical development of young people.
PHILADELPHIA – According to results of a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, men with prostate cancer who consumed the active compounds in green tea demonstrated a significant reduction in serum markers predictive of prostate cancer progression.
June 18, 2009 -- The U.S. mass transit system, the largest in the world, provides affordable and efficient transportation to more than 33 million riders each weekday. The system is generally considered one of the safest modes of travel. But recent public health studies have identified several sources of environmental hazards associated with mass transit, including excessive noise, a large and growing problem in urban settings.
Researchers at Brigham and Women's Hospital and the University of Michigan have developed a software program that prescribes a regimen for avoiding jet lag using timed light exposure. The method is described in an article published June 19 in the open-access journal PLoS Computational Biology.
Some parents may be unnecessarily switching infant milk formulas for their healthy infants. A study published in BioMed Central's open access Nutrition Journal, found that many parents misinterpret common baby behaviors as milk intolerance and needlessly switch formulas without consulting a health professional.
The team of researchers, led by Dr. Carol Lynn Berseth of Mead Johnson Nutrition, Indiana, USA, found that up to half of formula-fed infants experience a formula change during the first six months of life.
A small study has shown that people tend to believe that bottled water is somehow healthier than water from the tap. However, the research, published in the open access journal BMC Public Health, also shows that people are unsure exactly what these benefits might be and that they are rarely the main reason for choosing bottled.
Money spiders infected with Rickettsia bacteria are less likely to 'balloon' – that is, to use their silk as sails to catch gusts of wind and travel long distances. Researchers writing in the open access journal BMC Biology suggest that it may be in the bacteria's interests to ground the spiders and that this reduction in dispersal could reduce gene flow and impact on reproductive isolation within the meta-population.
PROVIDENCE, RI – A letter to the editor by Rhode Island Hospital infectious diseases specialist Leonard Mermel, DO, identifies characteristics of the outbreak of H1N1 in 1977 and speculates its impact on this pandemic. His letter is published in the June 20 edition of the journal the Lancet 2009 (vol 373 p2108-09).
