Anger and other negative emotions may be triggers for ischemic stroke, according to a study published in the December 14 issue of Neurology, the scientific journal of the American Academy of Neurology.
The study found that people who had strokes were more likely to have experienced anger or negative emotions in the two hours prior to the stroke than at the same time the day before the stroke. They were also more likely to have reacted quickly to a startling event, such as getti
As Americans queue up anxiously for flu shots, new research proposes a different sort of mass vaccination program to combat Lyme disease – a vaccine drive for mice.
A Michigan State University disease ecologist leads a novel ecological approach to battle Lyme disease. It proposes that ground zero is the forest floor, and immunizing the tiny critters there offers hope to ultimately reduce the number of dangerous tick bites that infect some 23,000 people in 2002 in the United S
New research suggests that rigid gas permeable contact lenses may help slow the progression of nearsightedness, or myopia, in young children.
At the end of a three-year study of more than a hundred 8- to 11-year olds, researchers determined that wearing rigid gas permeable (RGP) contact lenses slowed the progression of myopia by nearly 30 percent, compared to soft contact lens wear.
Only recently did researchers find that young children could handle the responsibility of
A fake Christmas tree may be more popular, but here’s a new reason to appreciate the real thing: Researchers have identified a group of anti-inflammatory compounds in the bark of the Scotch pine — widely used for Christmas trees — that they say could be developed into food supplements or drugs for treating arthritis and pain. The compounds, which show promise in preliminary cell studies, are likely to be found in other pine species as well, the scientists say.
Anti-inflammatory co
Powerful research tools that speed up vaccine development have led to the start today of human tests for a preventive vaccine against the respiratory disease SARS. The disease killed hundreds of people around the world before it was brought under control in 2003 with aggressive conventional public health measures.
Researchers at the Vaccine Research Center, National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), will conduct
Researchers at the University of Essex have found that high doses of vitamin B1 (thiamine) could lower cholesterol in diabetes patients and help prevent heart disease.
The results of the research project, led by Professor Paul J Thornalley of the Department of Biological Sciences, suggest that diabetics should avoid even mild thiamine deficiency and that thiamine supplements could significantly decrease the risk of heart disease and kidney failure.
Diabetes increases th
Doctors at Long Island Jewish (LIJ) Medical Center recently discovered a link between a common chemotherapy drug and a serious bone disease called osteonecrosis of the jaw (ONJ). The discovery, published in the Journal of Oral and Maxillofacial Surgeons, prompted both the US Food and Drug Administration (FDA) and Novartis, the manufacturer of bisphosphonates used in cancer chemotherapy, to issue warnings earlier this fall to physicians and dentists about the risk for this potential adverse eff
The drug methylphenidate (brand name Ritalin) increased activity in brains of children with attention-deficit/hyperactivity disorder (ADHD) as well as those with a reading disorder, researchers at Yale report in the American Journal of Psychiatry.
“During a test of divided attention, Ritalin increased activation in the basal ganglia, a structure of the brain involved in cognition and behavior,” said first author Keith Shafritz, former graduate student in the interdepartmental Neuros
Cancer screening tests can frequently produce false positive outcomes that may result not only in anxiety but also additional economic costs as well, according to research conducted by scientists at the Henry Ford Health System, Detroit, Mich., and published in the December issue of Cancer Epidemiology, Biomarkers & Prevention.
Among 1,087 individuals participating in a cancer screening trial who received a battery of tests for prostate, ovarian, colorectal and lung cancer, 43 per
Identifying asymptomatic people with genital herpes infection through targeted screening of high-risk groups may prevent disease transmission. However, widespread screening of pregnant women is unlikely to reduce the occurrence of herpes in newborns, according to an article in the January 1 issue of Clinical Infectious Diseases, now available online.
Herpes simplex virus type 2 (HSV-2) infects more than one-fifth of the United States population, but about 90 percent of those peop
Six months of treatment with celecoxib (Celebrex) in women at risk of developing breast cancer results in the reduction of estrogen receptor expression in breast cells, a research team at The University of Texas M. D. Anderson Cancer Center has found.
The surprising insight – that celecoxib may regulate a cell’s use of estrogen – could help explain the drug’s observed anticancer properties, says the study’s lead author, Banu Arun, M.D., associate professor in the Department of B
Fox Chase Cancer Center researchers have presented preliminary results of a clinical trial in which women received a two-week shorter course of radiation therapy than the current standard following a lumpectomy. The study was presented today at the annual Charles A. Coltman Jr. San Antonio Breast Cancer Symposium.
Radiation therapy daily for six or seven weeks after a lumpectomy is the standard course of treatment for many women with breast cancer who have had breast-sparing sur
Immunitor USA Inc., announces that its licensed vaccine candidate V-1 Immunitor (V1) has shown promising results in Phase II, placebo-controlled, clinical trial involving 47 HIV-infected individuals (http://www.emediawire.com/releases/2004/12/emw186195.htm)
The study was published in the special December issue of the Journal of Clinical Virology – the official journal of The Pan American Society for Clinical Virology and The European Society for Clinical Virology. The abstract o
If one of your New Year’s resolutions is to start a fitness regimen, you might want to seek professional help. A study by McMaster University’s Department of Kinesiology has found that people who are new to an exercise activity perform better when their goals are set by a fitness professional rather than by themselves.
In a study at McMaster University, exercisers were asked to perform a grip-strength task. After their first attempt, half of the participants set their own goal for the s
Transplant recipients have 96 percent survival rate after first year
Transplant researchers at the University of Pittsburgh’s Thomas E. Starzl Transplantation Institute have dramatically improved intestinal transplant graft survival, and reduced rejection and infection rates by successfully using a novel immunosuppression minimization protocol, thus improving patients’ overall quality of life and avoiding the use of several anti-rejection drugs, which can cause serious in
Travellers and night shift workers should save their money and look elsewhere for help to fall asleep.
The U.S. Department of Health and Human Services released information today about research on melatonin supplements. The research was conducted at the University of Alberta for the U.S. National Center for Complementary and Alternative medicine. U of A researchers did a comprehensive review of all studies on the use of melatonin supplements to treat sleep disorders. Some of the h
