No link between high blood pressure and headaches
Severe headaches are not a sign of high blood pressure, as is commonly thought, finds research in the Journal of Neurology Neurosurgery and Psychiatry. If anything, high blood pressure seems to reduce the risk of these headaches, the study shows. view more (2002-03-21)
Research provides clues to obesity's cause and hints of new approach for curbing appetite
Hot fudge sundaes and french fries aside, new research suggests obesity is due at least in part to an attraction between leptin, the hormone that signals the brain when to stop eating, and a protein more recently associated with heart disease. view more (2006-04-10)
New Generation of Contrast Agents Provides Hope for Enhanced Brain Tumor Diagnostics
In a pilot study of gadobenate dimeglumine (GD-BOPTA), the new contrast agent has yielded improved diagnostic imaging of brain tumors in magnetic resonance imaging (MRI) compared to standard contrast media. A team of researchers headed by PD Dr. Marco Essig, Division of Radiology of the Deutsches Krebsforschungszentrum (German Cancer Research... view more... (2004-05-03)
Doctors launch new effort to treat stroke more effectively
Just a small fraction of patients who have a stroke receive the only drug - TPA - available to treat the condition. Now doctors and scientists at the University of Rochester Medical Center have developed a potential new treatment that will reach a milestone in the next few months, when the experimental treatment is tested for the first time in... view more...

Contact lens wearers at risk from blinding infection
Some 2.2 million people wear contact lenses in England, with 900,000 alone in the southeast. Given the growing popularity in fashion contact lenses for night-clubbers, and for people who want a temporary change of eye colour, there needs to be greater awareness about the risks involved when people fail to clean their lenses properly. Dr Naveed... view more... (2003-11-03)
Vaccine thwarts the tangles of Alzheimer's
A new study by NYU Medical Center researchers shows for the first time that the immune system can combat the pathological form of tau protein, a key protein implicated in Alzheimer's disease. view more (2007-08-22)
New imaging analysis predicts brain tumor survival
As early as one week after beginning treatment for brain tumors, a new imaging analysis method was able to predict which patients would live longer, researchers from the University of Michigan Comprehensive Cancer Center have found. view more (2009-04-20)
BRIT1 allows DNA repair teams access to damaged sites
Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access. view more (2009-06-22)
West Nile virus' spread through nerve cells linked to serious complication
Scientists believe they have found an explanation for a puzzling and serious complication of West Nile virus infection. view more (2007-10-19)
Study Helps Explain Connection Between Sleep Apnea, Stroke And Death
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society. view more (2009-01-06)
Study links lead exposure to brain cancer in adults
People who are routinely exposed to lead on the job are 50 percent more likely to die from brain cancer than people who are not exposed. view more (2006-08-29)
Two cardiovascular proteins pose a double whammy in Alzheimer's
Researchers have found that two proteins which work in tandem in the brain's blood vessels present a double whammy in Alzheimer's disease. view more (2008-12-22)
UM scientists pinpoint critical molecule to celiac disease, possibly other autoimmune disorders
It was nine years ago that University of Maryland School of Medicine researchers discovered that a mysterious human protein called zonulin played a critical role in celiac disease and other autoimmune disorders, such as multiple sclerosis and diabetes. view more (2009-09-08)
Serotonin may play role in hardening of the arteries
A less active brain serotonin system is associated with early hardening of the arteries, according to a study presented today by University of Pittsburgh researchers at the 64th Annual Scientific Conference of the American Psychosomatic Society in Denver. view more (2006-03-06)
Damage to brain vessels increases the chance of dementia and depression
Dutch researcher Niels Prins has discovered that elderly people with a lot of damage to the small blood vessels in the brain have a greater chance of developing dementia or depression. The damage is visible on MRI scans as white matter lesions and infarcts of the brain. Elderly people with serious white matter abnormalities and infarcts were found... view more... (2004-04-13)
Radiologists use special MRI to identify brain cancer early
A special type of magnetic resonance imaging (MRI) can depict changes in blood volume in the brain that often precede cancerous transformation of brain tumors, according to a new study published in the April issue of the journal Radiology. view more (2008-03-25)
Tiny particles may pose threat to liver cells, say scientists
Researchers at the University of Edinburgh are to study the effects of nanoparticles on the liver. In a UK first, the scientists will assess whether nanoparticles -already found in pollution from traffic exhaust, but also used in making household goods such as paint, sunblock, food, cosmetics and clothes- can cause damage to the cells of the liver. view more (2006-04-05)
Listeria monocytogenes: how can a relatively innocuous food-borne pathogen induce a potentially fatal disease?
Listeria monocytogenes (L. monocytogenes) provokes listeriosis, a potentially fatal food-borne disease, which mainly affects pregnant women and immuno-compromised individuals where it can lead to death rate as high as 30%. Understanding the mechanism behind the disease is crucial to dealing with this serious health problem. In the latest Journal... view more... (2004-04-20)
Carnegie Mellon researchers to develop new drug delivery system
Carnegie Mellon University's Stefan F. Zappe is using adult neural stem cells to develop a new stem cell-based drug delivery therapy that may ultimately help treat a variety of inherited genetic disorders like Hunter syndrome. view more (2007-11-05)
New treatments prevent brain injury hours after stroke in rats
Two novel treatments - a basic compound found in every cell in the body and an extract of green tea - may prevent brain damage caused from stroke, according to two studies in rats led by a researcher at the San Francisco VA Medical Center. view more (2007-01-02)
