Generating electricity from air flow
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. view more (2009-11-23)
CHEMOEMBOLISATION OFFERS SURVIVAL BENEFIT FOR PEOPLE WITH LIVER CANCER (p 1734)
People with liver cancer that cannot be treated with surgical resection or transplantation could have an increased two-year survival if they are given chemoembolisation-a procedure in which blood supply to the tumour combined with the effect of chemotherapy inhibits cancer growth. There is no standard treatment for liver cancer when surgery,... view more... (2002-05-15)
Children of diabetics show signs of atherosclerosis
The blood vessels of people whose parents both have type 2 diabetes do not respond as well to changes in blood flow as those of people without a family history of diabetes, even if they do not have diabetes themselves. view more (2006-06-21)
Potential for Adult Stem Cells to Repair Hearts Damaged by Severe Coronary Artery Disease Investigated by Rush Cardiologists
Rush University Medical Center is one of the first medical centers in the country, and currently the only site in Illinois, participating in a novel clinical trial to determine if a subject's own stem cells can treat a form of severe coronary artery disease. view more (2007-02-02)
Atherosclerosis solution is likely many years away
It's the leading cause of heart disease and stroke: atherosclerosis--a disease characterized by the thickening of arterial walls, restricting blood flow like a narrow pipe. Preventing and reversing this disease is still largely a puzzle to scientists working to put all the right pieces into place and form a complete picture of health for millions... view more...

Study finds Viagra increases release of key reproductive hormone
Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals. view more (2007-08-27)
Acetaminophen safe to use after heart attack but doesn't protect the heart
Acetaminophen is safe to use as a pain reliever and fever reducer after a heart attack, but it does not protect the heart muscle, a new study using sheep and rabbits concluded. view more (2006-05-16)
Pitt-led Research Provides Insight Into Development of Common Congenital Circulatory Defects
University of Pittsburgh-led researchers could provide new insight into how two common congenital circulatory problems-aortic arch deformity and arteriovenous malformations (AVMs)-develop in humans, as reported in the June 15 edition of Developmental Biology. view more (2008-07-09)
Exercise is linked to later onset of dementia and Alzheimer's disease
Regular exercise is associated with a delay in the onset of dementia and Alzheimer's disease, according to a Group Health Cooperative/University of Washington study that will appear in the January 17 issue of Annals of Internal Medicine. view more (2006-01-17)
Glacial melting may release pollutants in the environment
Those pristine-looking Alpine glaciers now melting as global warming sets in may explain the mysterious increase in persistent organic pollutants in sediment from certain lakes since the 1990s, despite decreased use of those compounds in pesticides, electric equipment, paints and other products. view more (2009-10-22)
Draining away brain's toxic protein to stop Alzheimer's
Scientists are trying a plumber's approach to rid the brain of the amyloid buildup that plagues Alzheimer's patients: Simply drain the toxic protein away. view more (2007-08-13)
Drug controls high-altitude illness
Acetazolamide, a drug used to manage fluid retention in heart failure, controlled the serious effects of pulmonary edema, the accumulation of fluid in lung tissue from high altitude, as well as improved brain oxygenation, during a randomized, double-blind and placebo-controlled study. view more (2007-02-01)
A missing enzyme conveys major heart protection in pre-clinical work
Mice born without a certain enzyme can resist the normal effects of a heart attack and retain nearly normal function in the heart's ventricles and still-oxygenated heart tissue, according to a study by researchers at Duke University Medical Center. view more (2009-03-31)
Severe heart attack damage limited by hydrogen sulfide
Administering hydrogen sulfide (H2S) directly into the heart during a simulated heart attack significantly reduces the tissue and cell damage often seen in oxygen-starved organs, according to a new study from researchers at the University of Alabama at Birmingham. view more (2007-09-20)
Long airplane flight does not appear to increase risk of blood clots
Researchers simulating conditions of reduced cabin pressure and reduced oxygen levels, such as may be encountered during an 8-hour airplane flight, found no increase in the activation of the blood clotting system among healthy individuals. view more (2006-05-17)
Concrete flow researchers to use Argonne supercomputer
The Argonne National Laboratory of the Department of Energy (DoE) announced on Jan. 17, 2008, that a team of researchers at the National Institute of Standards and Technology (NIST) has been awarded 750,000 central processing unit (CPU) hours on the IBM Blue Gene/P supercomputer at the Argonne Leadership Computing Facility. view more (2008-01-24)
Some schoolboys get their kicks from partial self-strangulation
Schoolboys go in for partial self strangulation for kicks, using cloth towel dispensers, reports a study in Injury Prevention. Much older boys and adult men practice partial self strangulation by auto-erotic asphyxiation. The Canadian researchers cite five cases in which young boys attempted near strangulation using cloth towel dispensers in... view more... (2001-08-29)
'No muss, no fuss' miniaturized analysis for complex samples developed
The goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out. view more (2009-11-18)
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)
Mounting evidence shows health benefits of grape polyphenols
A growing body of research data suggests that consuming foods rich in polyphenols from grapes, including red wine, helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research. view more (2008-10-29)
