Sildenafil, an active agent used in the impotence drug Viagra, has been administered to seven young mountaineers on an Everest expedition, to test its effect on the lungs. Seven other men on the expedition are receiving a placebo.
The earlier a cardiac infarction is detected the better the patient's chances of survival. However, because tests for cardiac infarction check for protein molecules that are released from heart muscle during cell necrosis, and these enter the blood very slowly, it can take three hours to gain a reliable result.
Implants presently in use consist of a smooth or textured silicone shell filled with a silicone gel or saline solution. The latter has one decisive drawback - the breast may cool considerably in winter. Smooth silicone implants may also shift or turn.
The most expensive behavioural healthcare diagnosis, for sufferers and their insurers, is bipolar disorder, according to a study published in the American Journal of Psychiatry (160:1286-1290, July 2003).
Denmark - Regular drinkers significantly increase their risk of rectal cancer, but that risk is reduced if wine makes up a third or more of weekly consumption, according to research carried out by Professor Morten Grønbaek, at the Centre for Alcohol Research, National Institute of Public Health, Copenhagen, published in the journal GUT.
Injury to the brain and spinal cord cause permanent damage because, unlike bone and skin tissues, they lose the ability to repair themselves soon after birth.
France - Less than 50% of those affected by bowel cancer survive beyond five years after diagnosis. However, new research* surprisingly suggests that a high calorie diet may increase chances of survival for longer.
A newly invented 'Polypill', composed of currently available drugs, may act as a 'vaccine' against heart disease, according to new research published in the British Medical Journal (28 June. BMJ 2003;326:1419).
Lufthansa - the first airline company to offer high-speed broadband internet connection for data transmission - has used the trial phase of its new in-flight internet service, Lufthansa FlyNet, to test telemedicine potential on board.
Christopher Pryce, PhD, describes a promising test that can predict the onset of Alzheimer's disease some two years earlier than currently available tests can determine. Furthermore, the test can be used in non-human primates in order to research the neurobiology and pharmacology of such neurodegenerative illnesses. Dr. Pryce is conducting preclinical research with this test together with…
The European Health Telematics Association's (EHTEL) white paper and action plan for 2002-2003 states that without the creation of reimbursement processes and a regulatory framework for healthcare telematics the market for such devices will never grow.
Professor Wolfgang Schlegel, Head of the Department of Medical Physics at the German Cancer Research Centre, has been awarded the 2003 clinical section of the German Cancer Award, for significantly improving the precision with which radiation beams can be directed at a tumour.
Early in the history of endoprosthetic hip and knee joint replacements almost exclusively had cement fixations. Now the objective is to replace only the areas of joints actually affected by arthritis and which cause a patient pain.
Prostate cancer, the most common neoplasm in men, often progresses from an androgen-dependant state (and is commonly treated by androgen ablation therapies) to a hormone-refractory stage, therefore making hormone therapy ineffective. The response duration to androgen ablation therapy is finite and ultimately most prostate cancer will become hormone-insensitive.
Visual interfaces facilitate natural and simple interfaces for human-robot interaction. Nowadays there are many applications using these, such as teleconferencing with improved visual sensation, virtual reality systems, lip readers, assistance for mobility assistance for the disabled, etc. The use of head movements and gestures offers a natural way for severely disabled people, who cannot use a…
Alzheimer's disease is probably the best-known form of neurodegenerative disease, which is usually characterised by a progressive loss of cognitive, emotional and social abilities. But what actually happens in the brain? Read more about current research and therapeutic approaches to this form of dementia.
Many different forms, unclear origins: Multiple sclerosis (MS) is one of the most common neurological diseases that often leads to disability in those affected. Read more about current research and therapeutic approaches to MS.
