BOSTON - Travelers book plane tickets online, bank customers can check their accounts at any computer, and busy families can grocery shop online. Someday, even doctor visits could be among the conveniences offered via the Internet.
New technology allows student doctors to practice operations and other procedures on simulators before trying them out on real patients, just as pilots practice for emergencies on aircraft simulators. Medical educators feel that this will increase patient safety, by avoiding first-time mistakes being made on live patients. But does education by simulation actually work?
The large forest fires that sweep through Indonesia in dry periods are not only the result of severe drought. A team of researchers, including Veni grant winner Guido van der Werf, has analyzed the density of smog during forest fires. They have now established that the intensity of the forest fires is directly linked to population density and land use.
A main reason why viruses such as HIV or hepatitis C persist despite a vigorous initial immune response is exhaustion. The T cells, or white blood cells, fighting a chronic infection eventually wear out.
Researchers at Emory Vaccine Center have demonstrated that exhaustion is driven by how the immune system detects infecting viruses.
Blood stem cells literally go with the flow, according to a new report published as an immediate early publication in the journal Cell, a Cell Press journal, on May 13th. Researchers have found that a heart beat and blood circulation are critical signals for the production of blood-forming, or hematopoietic, stem cells in the developing embryo.
The method of building a rabbit rectal VX2 carcinoma model by injecting the cell suspension of VX2 cells into the wall of the rectum guided by X-ray fluoroscopy is feasible. The advantages of the model are ease of establishment, short growth period, and high stability.
If two people have the same genetic disease, why would one person go blind in childhood but the other later in life or not at all?
DALLAS - May 13, 2009 - One reason antidepressant medication treatments do not work as well in real life as they do in clinical studies could be the limited type of study participants selected, researchers at UT Southwestern Medical Center have found.
The recession will likely signal the end for many of Britain's smaller buy-to-let landlords, and poses a grim threat to city-centre new build properties, warn experts at The University of Nottingham.
New research suggests that while the buy-to-let market will survive the recession, a "property neutron bomb" will see the disappearance of many smaller private landlords.
Clinicians are missing golden opportunities to identify heart disease before patients start displaying symptoms, according to a study of 13,877 people published in the May issue of UK-based IJCP, the International Journal of Clinical Practice.
Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine.
Why are former business executives and attorneys volunteering more time to help their communities? Why do the children of immigrants assume values very different from those of their parents? Why has the size of Japanese families declined substantially?
LAS VEGAS, NV (May 8, 2009) -- A new device designed to close a common heart defect known as a patent foramen ovale (PFO) is safe and effective at 90-days follow up, according to a new study released today at the Society for Cardiovascular Angiography and Interventions (SCAI) 32nd Annual Scientific Sessions in Las Vegas.
Amsterdam, the Netherlands: New research that uses an innovative approach to study, for the first time, the relative contributions of food and exercise habits to the development of the obesity epidemic has concluded that the rise in obesity in the United States since the 1970s was virtually all due to increased energy intake.
In the 25 years between 1981 and 2006 mortality rates from coronary heart disease (CHD) in Iceland decreased by a remarkable 80% in men and women aged between 25 and 74 years. How could such a huge decline be explained? Were the health services of Iceland so much better, or were its citizens reducing their risks?1
