An experimental model, developed by scientists from VNIIEF in Sarov and their colleagues, ophthalmologists from ‘Mikrokhirugiya Glaza’ [Optical Microsurgery] means that it is possible, quite literally, to see the world with someone else’s eyes. Financial support was given to the researchers for the creation of a model of the human eye by the International Science and Technology Center.
‘The actual initiators of the project were the Moscow-based developers of new artificial crystalline l
Patent foramen ovale may be ’innocent bystander,’ not source of stroke
Mayo Clinic researchers have found that — contrary to current thinking by some in the medical community — a patent foramen ovale (PFO), a small hole between the two upper chambers of the heart, does not predestine an individual to a stroke later in life. Findings will appear online on Friday, Dec. 9 in the Journal of the American College of Cardiology.
“In the general population, it doe
Two large, randomised, placebo-controlled studies presented at the inaugural conference of the World Association of Sleep Medicine (WASM; Berlin, Germany) in October demonstrate that pramipexole delivered both short-term and sustained efficacy in patients suffering from Restless Legs Syndrome (RLS)1,2 enrolled in these trials.
New data from a randomized, placebo-controlled “withdrawal” study1 show that discontinuation of pramipexole leads to rapid worsening of RLS in patients who had pre
The targeted agent AMN107 can produce dramatic benefits in patients with some forms of leukemia that are resistant to Gleevec, the standard therapy for these cancers, say researchers at The University of Texas M. D. Anderson Cancer Center (meeting abstract #37).
At the 47th Annual Meeting of the American Society of Hematology (ASH), the investigators reported marked improvement in outcome in all three phases of chronic myeloid leukemia (CML) as well as benefit in treating a form
The reliability of a prostate cancer-screening test may be compromised by lifestyle and demographic factors, according to a new study. Published in the January 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study reveals the (rate of) change in concentration of prostate specific antigen (PSA) over time–a calculation called PSA velocity–can be significantly affected by age, race, and diet, leading to falsely lower or elevated values and possible misinterpreta
OHSU study shows platinum-based ototoxicity in children prevalent, but new drugs offer prevention hope
By 14, Peter Johnson had survived brain cancer and a relapse of the disease in his shoulder. But it was treatment for the last tumor that would create his life’s greatest challenges.
Johnson, now 33, has suffered since 1986 from the effects of ototoxicity, a condition in which platinum-based chemotherapy drugs, such as carboplatin and the more common cisplatin,
Pioneering research by a North East scientist could lead to a cure for some of the most deadly antibiotic-resistant diseases.
Toxic Shock, Septicemia and the flesh-eating disease necrotizing faciitis are just some of the potentially fatal invasive infections caused by the streptococcus bacterium, which has increased significantly over the past 10 years.
Until now, scientists have not understood what turns this ordinary bacterium – which is best known as the cause of so
Dermatologists seem to agree that something in milk and dairy products may be linked to teen-age acne.
But is it hormones and “bioactive molecules,” as a study in the Journal of the American Academy of Dermatology suggested, or is there something else?
University at Buffalo dermatologist Harvey Arbesman, M.D., says there could be something else: Iodine.
Arbesman, a UB clinical assistant professor of dermatology and social and preventive medicine, details his reas
A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry, a brain imaging study at the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) has discovered. Scans of the hormone oxytocin’s effect on human brain function reveal that it quells the brain’s fear hub, the amygdala, and its brainstem relay stations in response to fearful stimuli. The work at NIMH and a collabor
Patients speak out regarding impact on intimacy, relationships and careers
Results released today from the Voices of UC survey of 1,000 ulcerative colitis (UC) patients underscore the extensive burden of the disease. UC is a debilitating chronic disease affecting more than 500,000 Americans, for whom there is no medical cure. While UC affects more people in the United States than multiple sclerosis or cystic fibrosis, general awareness of the disease is disproportionately lower.
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans. Appearing in the December 8 issue of the journal Nature, the study investigates the bacterium Vibrio cholerae and its ability to attach to a host, enabling it to multiply and adding to the risk of infecting humans.
Women with breast cancer face increased risk of developing a second cancer
A new large-scale study on women with breast cancer found a 25 percent increase in the risk of developing a new non-breast cancer compared to women without cancer. The study, published online December 8, 2005 in the International Journal of Cancer, the official journal of the International Union Against Cancer (UICC), is available via Wiley InterScience.
Breast cancer is the most common cancer a
Asthma patients who don’t respond to steroid treatment suffer repeated asthma attacks, and are at greater risk of dying from the condition. Researchers from King’s College London have found that vitamin D3 could substantially improve the responsiveness of these patients to steroid treatment, offering them hope of an improvement in their condition. Their results are published today in the Journal of Clinical Investigation.
Asthma is usually treated very effectively with inhaled s
It’s a scene football fans will see over and over during the bowl and NFL playoff seasons: a player, often the quarterback, being slammed to the ground and hitting the back of his head on the landing.
Sure, it hurts, but what happens to the inside of the skull? Researchers and doctors long have relied upon crude approximations made from test dummy crashes or mathematical models that infer – rather loosely – what happens to the brain during traumatic brain injury or concuss
Pairing the targeted therapy Herceptin with chemotherapy in patients with early stage breast cancer significantly increases disease-free survival time in women who test positive for a genetic mutation that results in a particularly aggressive form of the disease, according to large, international study.
The study also tested Herceptin with a chemotherapy combination that eliminated Adriamycin, an anthracycline commonly used to treat breast cancer but a drug that, when used with He
The millions of mammography exams performed each year in Europe save thousands of women’s lives, but if the data from all breast cancer screening procedures was made available to clinicians and researchers across the continent they could save many more. That is the vision behind MammoGrid.
The MammoGrid project is studying the commercial possibilities for its distributed computing environment that employs existing Grid technologies for the creation of a European database of mam
