Researchers have uncovered a specific signaling mechanism that contributes to the development of colorectal cancer, one of the most common deadly human cancers. The discovery furthers the understanding of mechanisms that contribute to disease progression and provides new avenues for development of therapies for colorectal cancer.
According to study author, Dr. Marcus F. Neurath from the University of Mainz in Germany, “Several lines of evidence support an important role of TGF-b
Magnetic resonance imaging (MRI) may be as accurate as computed tomography (CT) in detecting acute bleeding in the brain in patients showing signs of stroke, and more accurate than CT in revealing chronic bleeding in the brain, according to a study in the October 20 issue of JAMA.
Noncontrast computed tomography (CT) has been the standard brain imaging technique used for the initial evaluation of patients with acute stroke symptoms, greatly due to its capacity to rule out the p
A Stony Brook University researcher is testing a new form of aspirin–one that is much more potent than its commercially available counterpart, but with almost none of the side effects–to determine whether it can be used to prevent colon cancer in patients who are prone to the disease.
The study of the new medication–called nitric oxide-donating aspirin, or nitroaspirin–is supported by a $3.2 million grant from the National Cancer Institute. Basil Rigas, M.D., Professor of Medic
A common antibacterial and antifungal ingredient used in mouthwashes and tooth paste may have another positive medicinal use: protection against skin cancer.
According to new studies, sanguinarine was shown to enhance production of proteins that induce cell death, or apoptosis, in cells damaged by ultraviolet-B (UVB) radiation. The alkaloid also restricts skin cell production of other pro-proliferation proteins. “This natural compound may protect skin from cells that acquire the
Ductal lavage is not an effective method for detecting breast cancer, according to a new study in the October 20 issue of the Journal of the National Cancer Institute.
Ductal lavage–a method used to collect cells from the milk ducts of the breast–has been proposed as a screening tool for cancer detection because ducts that yield fluid were thought to be more likely to contain cancer cells. Interest in the procedure was spurred by a study in which ductal lavage detected cancer i
Global warming poses an increasingly sizeable threat to the continued existence of man. James Lovelock, atmospheric chemist and author of Gaia warns that the gravity of the situation facing Earth’s inhabitants is greater than we have yet realized and accepted. Lovelock sets forth his predictions — and proposed solutions — in a commentary piece published this week in Atmospheric Science Letters.
The laws of Gaia – a hypothesis set forth by Lovelock – imply that any species that
Telephone conference calls are widely used by business, but they also have great value for people outside work. New ESRC funded research, shows people such as the elderly, who may be socially isolated due to mobility problems, enjoy conference calls.
The study was led by Professor Andrew Monk of the Department of Psychology at the University of York. He argues the calls could be made more enjoyable by developing technologies that support electronic socialising, providing visual aids
Randers, 18 October 2004 Vestas receives order for a 150 MW wind power plant in Canada The Vestas Group has received an order for 83 units of V80-1.8 MW wind…
Following on from the success of EUREKA project E! 2534 THERMOPOLE, which developed thermoplastic lampposts that save lives by bending on impact, EUREKA project E! 2535 FACTORY PANELFORM has adapted the thermoplastic technology to produce sandwich section panels for a market worth over €20 million a year.
The recyclable panels can be produced in three-metre wide sections at a rate of four metres per minute, in a variety of colours and finishes. The new material is stronger and more
Scattered in universities across Europe, a 250-strong team of students have never collectively met in person, but between them they have built a space-ready satellite. SSETI Express is currently being integrated in an ESA cleanroom for a planned launch in May next year.
Collaboration between the pan-European network of students, universities and experts involved in the Student Space Education and Technology Initiative (SSETI) has been carried out via the internet. Now that the co
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, show the eastern rim of the Martian impact crater Huygens.
The images were taken during orbit 532 in June 2004 with a ground resolution of approximately 70 metres per pixel. The displayed region is centred around longitude 61° East and latitude 14° South.
Huygens is an impact structure, about 450 kilometres wide, located in the heavily cratered southern highlands of
Scientists have made a rare discovery from over 500 million years ago that provides new information on how a record of the past was perfectly preserved by nature.
Geologists at the University of Leicester have found that pyrite – or fool’s gold – replaced soft tissues, thereby preserving animals to their smallest details for posterity.
Dr Sarah Gabbott and colleagues, of the University of Leicester Department of Geology, found creatures with the very hairs on their
It’s a good thing that the now eight-year-old son of Miklos Gratzl, a Case Western Reserve University biomedical engineer, got a splinter in his finger one day – at least for the sake of science. With apologies to his son – instead of an “Ouch!” moment, for Gratzl it was more of an “A-ha!” moment.
As he was removing it from his son’s finger, the splinter gave him an idea: Since it showed no open wound in the skin, he thought to himself that a sensor like a sliver would be ideal
Get a group of scientists together and mention the word “chlorine” and watch the sparks start to fly. That’s exactly what happened at a forum on a different, but related, topic of sustainability, sponsored by the news magazine Chemical & Engineering News, a publication of the American Chemical Society, the world’s largest scientific society.
As a result of a “vigorous and provocative debate” about chlorine at that forum, the magazine’s editors asked two leadin
A study conducted by researchers at Case Western Reserve University found that patients who used a relaxation technique, called “systematic relaxation,” experienced a substantial decrease in pain after undergoing surgery. The systemic relaxation technique, which consists of sequentially relaxing each major muscle group in the body, was shown to improve comfort by more than 50 percent compared to patients not using the technique. Patients in the study could also request pain medication.
Pre-school youngsters with type I diabetes can be treated as successfully with insulin pumps as with daily injections, researchers at the Indiana University School of Medicine report.
A clinical trial at the Riley Hospital for Children studied 20 patients 5 years old or younger receiving treatment with continuous insulin infusion by pump and 17 who were receiving injection therapy. Physicians compared control of blood sugar levels, parents’ satisfaction and safety in both g
