A new digital angiography flat panel system reduces the radiation dose to patients undergoing interventional treatment for liver cancer by about one-fourth, a new study shows.
The study compared the radiation dose to patient’s skin during transcatheter arterial embolization, a procedure that blocks the flow of a blood to a tumor. Doses were assessed for 12 patients using a new angiography unit with a digital flat-panel system and 12 using a conventional unit for angiogra
Vending machines that allow consumers to dial-up personalised milkshakes with nutritional supplements could find their way into gyms, schools and doctors’ surgeries in as little as 3 years, prompting calls for health warnings by experts.
The machines asks consumers questions regarding their age, gender and exercise regime to specific health conditions like diabetes. And although the consumer can choose flavours and colours, the machine decides how much vitamins, minerals, fatty acid
Low Cost Fails To Ensure The Availability Of Lifesaving Drug
A life-saving drug used to treat seriously-ill pregnant women in Africa is not widely available – in part because it’s too cheap. Magnesium sulphate is a low-cost but effective treatment for eclampsia and pre-eclampsia in pregnant women. The disease, although relatively rare, claims the lives of more than 63,000 women a year, mostly in poorer countries and can also kill unborn children.
But researchers at the L
White blood cells may be cause of dementia in people with AIDS
Researchers studying the evolution of the human immunodeficiency virus (HIV) in the brain have found that the body’s own defenses may cause HIV-related dementia.
Publishing in the Sept. 2005 issue of the Journal of Virology, the researchers show that HIV in the temporal lobe mutates at a rate 100 times faster than in other parts of the body, triggering white blood cells to continually swarm to attack the infe
Mayo Clinic research reinforces the importance of blood sugar control from onset of diabetes to prevent nerve damage later
Mayo Clinic researchers have found that subtle change in nerve conduction is the first reliable sign of nerve complications from diabetes and that this change can be measured long before other symptoms or signs of nerve damage develop.
“We’ve found what we believe is the earliest sign of nerve change due to diabetes,” says Peter J. Dyck, M.D., Mayo
Pedagogues and psychologists involved in education are striving to make training more efficient. To achieve this, it would be useful to understand what happens in a trainee’s brain during learning. Only neurophysiologists can sort that out, however, not everything is clear to them yet.
Thus, it can be expected that memorizsation and reminiscence processes (which make the essence of training) should be reflected in changes of the brain’s electrical activity nature. It means that th
Pain in the back and neck leads to impaired memory and powers of concentration. Moreover, such pain hastens mental aging. This has been shown by Stefan Söderfjell in a new dissertation at Umeå University in Sweden.
People in pain often experience difficulty in concentrating, solving problems, and remembering things. Umeå researcher Stefan Söderfjell has now shown in his doctoral dissertation that people in pain actually do have these problems with their so-called cognitive functions.
Doctors may drive unnecessary procedures
Patients with irritable bowel syndrome (IBS) use over 50 percent more health resources than people without the disorder. Even though there are definitive guidelines to diagnose IBS through simple blood tests, many IBS patients have additional procedures and surgeries that rarely result in relief or any additional diagnostic findings.
“It is difficult to know why patients with IBS have such a high use of healthcare resources, and
Scientists at Rosalind Franklin University publish new findings in the Journal of Pharmacology and Experimental Therapeutics
A methamphetamine epidemic rages across the United States with addicts blinded by uncontrollable desires for a drug that eventually thrusts them into a dire and catastrophic existence. Doctors don’t have any effective treatments for these addicts, or for any other drug addicts; drug addiction is a disease that remains a medical mystery. A recent study led
The Swiss Paul Scherrer Institute (PSI) in Villigen and Siemens Medical Solutions (Med) in Erlangen, Germany, have recently signed a cooperation contract. Both partners agreed to a closer collaboration in proton therapy planning – an important component of a particle therapy solution.
Within the scope of the agreement, Siemens has access to the know-how of the therapy planning system at the Paul Scherrer Institute. Both partners are joining forces to further develop proton the
Medics at The University of Manchester have discovered a way to treat Irritable Bowel Syndrome (IBS) using hypnotherapy.
Up to eight million people in Britain suffer from IBS, with symptoms including diarrhoea, pain and bloating. The condition can seriously affect sufferers’ quality of life and finding treatment can be difficult, leading many doctors to feel they can do little to help.

It won’t be long before automated DNA test contribute to providing more knowledge about the up to now nearly unknown sexually transmitted mycoplasma – truly more widespread than chlamydia. Mycoplasma is a bacterial infection of the genitals.
More effective and comprehensive testing of target groups could reveal more about the as yet little studied sexually transmitted bacterial disease mycoplasma, just is as already done to demonstrate other sexually transmitted illnesses such as
Veterinary scientists at the University of Liverpool want to recruit 20 Labrador dogs to a new study into osteoarthritis of the elbow.
The study will help vets understand how osteoarthritis progresses in dogs and how treatment may slow the disease down. To take part in the study Labradors must be less than two years old and show early signs of elbow osteoarthritis.
A mobile Magnetic Resonance Imaging (MRI) scanner will make regular visits to the University’s Small Anim
Junk food could be made healthier by adding an extract of an exotic type of seaweed, say British scientists.
The highly-fibrous seaweed extract, alginate, could be used to increase the fibre content of cakes, burgers and other types of food which usually contain large amounts of fat and a low degree of healthy nutrients, say the team.
Scientists at the University of Newcastle upon Tyne publish their findings in the academic journal Critical Reviews in Food Science and N
French explorers Olivier Pezeron and Arnaud Fauvet enjoyed gourmet space food on their 20-day Greenland expedition this summer. The menu, prepared by a French chef for ESA astronauts, included delicacies such as sword fish, duck with capers and Thai chicken.
When they set out on their 600 km skiing expedition on 2 June from Kangerlussuaq, Greenland, space food was among the 100 kg of luggage stacked on the sledges they pulled behind them. The meals were prepared by the French go
Playing an increasingly important role in the prevention of cardiovascular disease (CVD), controlling one’s weight through healthy eating and regular exercise can directly reduce the risk of heart disease and also the impact of an existing heart condition. The European Society of Cardiology (ESC) joins the World Heart Federation in trumpeting the importance of ‘Healthy Weight, Healthy Shape for a Heart for Life’ on World Heart Day, 25 September 2005.
