The average living cell needs communication skills: It must transmit a constant stream of messages quickly and efficiently from its outer walls to the inner nucleus, where most of the day-to-day decisions are made. But this rapid, long-distance communication system leaves itself open to mutations that can give rise to a "spam attack" that promotes cancer.
Ebola whole virus vaccine shown effective, safe in primates
Friday, 27 March 2015
An Ebola whole virus vaccine, constructed using a novel experimental platform, has been shown to effectively protect monkeys exposed to the often fatal virus. The vaccine, described in the journal Science, was developed by a group led by Yoshihiro Kawaoka, a University of Wisconsin-Madison expert on avian influenza, Ebola and other viruses of medical importance.
New MIND diet may significantly protect against Alzheimer's disease
Thursday, 26 March 2015
A new diet, appropriately known by the acronym MIND, could significantly lower a person's risk of developing Alzheimer's disease, even if the diet is not meticulously followed, according to a paper published online for subscribers in March in the journal Alzheimer's & Dementia: The Journal of the Alzheimer's Association.
Medical expansion has led people worldwide to feel less healthy
Friday, 20 March 2015
Across much of the Western world, 25 years of expansion of the medical system has actually led to people feeling less healthy over time, a new study has found. A researcher at The Ohio State University used several large multinational datasets to examine changes in how people rated their health between 1981 and 2007 and compared that to medical expansion in 28 countries that are members of the Organization for Economic Co-operation and Development.
Study raises concerns about reporting of noninferiority trials
Thursday, 19 March 2015
An examination of the reporting of noninferiority clinical trials raises questions about the adequacy of their registration and results reporting within publicly accessible trial registries, according to a study in the March 17 issue of JAMA. Noninferiority clinical trials are designed to determine whether an intervention is not inferior to a comparator by more than a prespecified difference (known as the noninferiority margin).
Oncologists reveal reasons for high cost of cancer drugs in the US, recommend solutions
Monday, 16 March 2015
Increasingly high prices for cancer drugs are affecting patient care in the U.S. and the American health care system overall, say the authors of a special article published online in the journal Mayo Clinic Proceedings. "Americans with cancer pay 50 percent to 100 percent more for the same patented drug than patients in other countries," says S. Vincent Rajkumar, M.D., of Mayo Clinic Cancer Center, who is one of the authors.
A new molecule-making machine could do for chemistry what 3-D printing did for engineering: Make it fast, flexible and accessible to anyone. Chemists at the University of Illinois, led by chemistry professor and medical doctor Martin D. Burke, built the machine to assemble complex small molecules at the click of a mouse, like a 3-D printer at the molecular level.
