Your IQ and extracurricular interests as a teenager may forecast your memory and thinking abilities decades later.
A new study by researchers at the University Memory and Aging Center, affiliated with Case Western Reserve University (Case) and University Hospitals of Cleveland (UHC), found that persons who were more active in high school and who had higher IQ scores, were less likely to have mild memory and thinking problems and dementia as older adults. Their results are published
Actelion Ltd (SWX: ATLN) announced today that a study published in the July edition of the Journal of Neurosurgery suggests that clazosentan can reduce the number and severity of cases of vasospasm following aneurysmal subarachnoid haemorrhage (SAH).1
Vasospasm occurs 5-14 days following SAH and leads to strokes and neurological deficits that cause significant disability to patients and is a major cause of death. As many as 70% of people who have aneurysmal SAH may have arteria
A recently completed study by scientists at the Oregon Research Institute (ORI) in Eugene confirmed earlier findings from a pilot study that walking on a cobblestone mat surface resulted in significant reductions in blood pressure and improvements in balance and physical performance among adults 60 and over. An article published in an early online publication of the Journal of the American Geriatrics Society summarizes the study results in a randomized trial.
“These are very exciting
A study published today in the prestigious journal Nature by Dr. Michael Petrides and colleagues at the Montreal Neurological Institute (MNI) at McGill University, challenges current thinking that speech developed as a result of new structures that evolved in the human brain. Dr. Petrides and colleagues have identified a distinct brain region that controls jaw movements in macaque monkeys that is comparable to Broca’s area – the region in the human brain critical for speech production. This disc
A steady diet of e-mails that promote healthy behavior can change a person’s outlook and behavior regarding healthier eating and increased physical activity, says a new study from the University of Alberta.
The 12 week study of 2,598 Canadian workers will be published in the July/August 2005 edition of the American Journal of Health Promotion.
People receiving the e-mails showed an increase in physical activity levels and also had more confidence in being able t
Study will be published in June 30 New England Journal of Medicine
A new study shows that a drug, called daclizumab, is effective at reducing organ rejection and risk of infection in heart transplant patients. The multi-center study by cardiologists from the United States, Sweden, Germany and Canada will be published in the June 30 issue of The New England Journal of Medicine.
Oregon Health & Science University cardiologist Ray Hershberger, M.D., was the lead author of t
A few X-ray measurements can help determine whether chronic problems with the hard-to-reach frontal sinuses can be corrected with surgery, according to a new study.
“The frontal sinus is behind the forehead and it has a very tortuous drainage,” says Dr. Stil E. Kountakis, vice chair of the Medical College of Georgia Department of Otolaryngology-Head and Neck Surgery. “It’s the most difficult sinus to work with.”
The good news is the frontal sinuses, which run parallel to
Study shows effectiveness of doxycycline in slowing disease progression
A tetracycline antibiotic, doxycycline, has been successfully used to treat a wide-range of bacterial infections. In addition to its effects as an antibiotic, doxycycline has other actions as a drug and, in laboratory studies with animals and with human tissue, can inhibit the degradation of cartilage in a way that could be useful for the treatment of osteoarthritis (OA). OA is a common form of arthritis associat
Which is more likely to happen – you being in a car wreck or being bitten by a shark?
Those who answered that cars are greater killers win a free trip to the beach. It’s really no contest, says a Texas A&M University professor. Your chances of being in a wreck are far greater than being a shark’s lunch, says John McEachran, a professor of wildlife and fishery sciences who has studied sharks for years.

Child Survival is Affordable at only $1.23 per capita in 42 Countries
Six million children could be saved if $5.1 billion in new resources for preventive and therapeutic interventions were provided each year, according to researchers from the Johns Hopkins Bloomberg School of Public Health and other institutions. Approximately 90 percent of all child deaths occur in 42 countries around the world. In those countries, the average cost per child saved would be $887 or $1.23 per cap
The more seniors watch television, the greater their negative images of aging may be, but maintaining a diary of viewing impressions increased their awareness of the negative stereotyping on television, researchers at Yale report in the Journal of Social Issues.
“These findings suggest that the promotion of awareness could provide a means of helping elders confront ageism,” said lead author Becca Levy, associate professor in the Department of Epidemiology and Public Health at Yale Scho
A good night’s sleep triggers changes in the brain that help to improve memory, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC).
These findings, reported in the June 30, 2005, issue of the journal Neuroscience and currently published on-line, might help to explain why children – infants, in particular – require much more sleep than adults, and also suggest a role for sleep in the rehabilitation of stroke patients and other individua
Employment in computer- and internet-related fields is notoriously volatile, but recent developments have raised concerns about the long-term future: The number of undergraduates seeking computer science degrees is down sharply since 2000. The number of women seeking such degrees has plunged. And few minority students are winning advanced degrees in the field.
Now a new study from AAAS has concluded that recruitment of “non-traditional” students into computer science studies and jobs wil
A study on markers of inflammation in smokers and non-smokers shows that it can take several years after smoking for changes in the blood to return to normal. The researchers, Arvind Bakhru and Thomas Erlinger, gathered data on 15,489 US adults between 1988 and 1994 in the Third National Health and Nutrition Examination Survey. They found that the inflammatory markers, C-reactive protein, white blood cell count, albumin, and fibrinogen, took longer to return to normal after smokers quit than did mor
The theory that the mind works like a computer, in a series of distinct stages, was an important steppingstone in cognitive science, but it has outlived its usefulness, concludes a new Cornell University study. Instead, the mind should be thought of more as working the way biological organisms do: as a dynamic continuum, cascading through shades of grey.

UCI study shows how newly identified signaling protein helps control retinal development
In discovering a protein that helps organize the development of the retina, UC Irvine researchers have found a new molecular mechanism that may allow for stem cell-based therapies to treat eye disorders such as retinal degeneration.
The finding also reveals how the retina’s own stem cells can be directed to aid the growth of new cells to replace diseased or dying ones in th
