High hourly levels of air pollution, more than double the risk of one type of stroke, suggests research published ahead of print in Occupational and Environmental Medicine.Currently, the risk of respiratory and cardiovascular problems tends to be linked to the average daily amount of air pollution, rather than variations in hourly levels.The researchers assessed data on stroke deaths in people aged 65 years and older, occurring betwe...Thursday, 21-Sep-2006 / [ Details... ]
In an example of biological irony, the same white blood cell chemistry known to damage kidneys used for transplants may also help prevent such damage, according to a federally funded study in genetically engineered mice at Johns Hopkins.Researchers have long known that when blood flow is cut off and then returned to transplanted kidneys or other organs, immune system cells called T lymphocytes produce toxic natural chemicals that contribute to isch...Thursday, 21-Sep-2006 / [ Details... ]
Doctors should consider whether patients are at high risk of stomach ulcers before prescribing aspirin treatment. A study published today in the open access journal BMC Medicine reveals that low-dose aspirin treatment may be responsible for one extra case of gastrointestinal complications, which include ulcer bleeding or perforation, in every 50 aspirin users per year in susceptible groups, such as older men with a history of peptic...Wednesday, 20-Sep-2006 / [ Details... ]

Fetal survival following a preeclamptic pregnancy has improved substantially over the last 35 years in Norway, likely due to a reduction in stillbirths and improvements in clinical management, according to a study in the September 20 issue of JAMA: The Journal of the American Medical Association.Preeclampsia (a potentially dangerous condition that may develop in late pregnancy with symptoms that include high blood pressure, fluid retention, e...Wednesday, 20-Sep-2006 / [ Details... ]
In a medical case of Jekyll and Hyde, carbon monoxide - the highly toxic gas emitted from auto exhausts and faulty heating systems - has proven effective in treating the symptoms of pulmonary arterial hypertension (PAH), an extremely debilitating condition that typically leads to right heart failure and eventual death.The new findings, made in an animal study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and the ...Wednesday, 20-Sep-2006 / [ Details... ]
A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found.The study, published in the Sept. 18 online issue of the Journal of Cell Biology, helps illuminate the very first steps involved in metastasis, the spread of cancer ...Wednesday, 20-Sep-2006 / [ Details... ]
