The risk of thyroid cancer rises with increasing radiation dose, according to the most thorough risk analysis for thyroid cancer to date among people who grew up in the shadow of the 1986 Chernobyl power-plant disaster.
The incidence of thyroid cancer was 45 times greater among those who received the highest radiation dose as compared to those in the lowest-dose group, according to a team of American and Russian researchers led by Scott Davis, Ph.D., and colleagues at Fred Hutchinso
A new study from Fred Hutchinson Cancer Research Center reveals what may be the earliest step in the development of prostate cancer. The finding could open the door to new tests that predict whether the cancer will become aggressive and the development of treatments to prevent the condition from progressing.
The study, published in the Sept. 1 issue of Cancer Research, found that when mice are engineered to lose a single copy of a gene called Rb in their prostate, they develop a pre
“Other studies have indicated a benefit for heart attack patients in beginning treatment with statins relatively early, so today the standard practice is to prescribe them upon discharge,” says R. Scott Wright, M.D., the Mayo Clinic cardiologist who was the study’s lead investigator in North America. “Our new findings suggest they should be given even earlier, as soon as the patient arrives at the hospital.”

Internet companies can boost sales and build trust with online shoppers by providing clear and readily available privacy disclosures, according to a recent UC Irvine study.
“Surveys have demonstrated that online shoppers are concerned about their privacy, specifically about the confidentiality of the personal data they provide to Web retailers,” explained Alfred Kobsa, author of the study and professor of informatics in UCI’s Donald Bren School of Information and Computer Sciences. “T
A major Canadian-led global study has found that the vast majority of heart attacks may be predicted by nine easily measurable factors and that these factors are the same in virtually every region and ethnic group worldwide.
The INTERHEART study looked at more than 29,000 people in 52 countries and from all inhabited continents of the world. The study was presented Aug. 29 at the European Society of Cardiology (ESC) Congress in Munich, Germany by Dr. Salim Yusuf, a professor of medic
“Our research shows that the concept of time is easier to write off than is money,” said Erica Okada, a University of Washington assistant professor of marketing who co-authored the study with Stephen Hoch, professor of marketing at the University of Pennsylvania’s Wharton School. “People are relatively certain about how much their money is worth, but when it comes to their time, people are less certain about its value.”
Unlike previous research that focused almost exclusively
US saltwater recreational fishing catch rivals commercial fisheries for many depleted fish stocks including red snapper, black seabass, and lingcod
Taking a hard look at the common belief that recreational fishing accounts for only 2-3% of total landings in the U.S., a new study published in the journal Science (August 26th) reveals that recreational catches account for nearly a quarter of the total take of over fished populations, including many of the most economically valuable sp
Early results of a UK study published online today by THE LANCET (Wednesday 25 August 2004) suggest that a surgical procedure to repair aortic aneurysm that is less invasive than conventional open surgery could reduce death within a month of surgery by around two-thirds.
Abdominal Aortic Aneurysm (AAA) is a dangerous swelling of the abdominal aorta which has an increased chance of rupture if it is larger than 5•5cm—a majority of people die from ruptures. The cause of AAA is complex
Researchers have developed a powdered form of an anthrax vaccine that could potentially be inhaled through the nose and eliminate the need for needle injections. The new vaccine, which appears promising in preliminary animal studies, may offer a faster and easier way to protect the general population as well as soldiers on the battlefield in the event of a deadly bioterror attack, the researchers say.

Researchers in Italy have observed significant reductions of gray matter volume in areas of the brain associated with language processing among people with a family history of dyslexia in comparison with controls with no reading problems. Published in the August 24 issue of Neurology, the scientific journal of the American Academy of Neurology, the study also lends support to previous studies suggesting intensive reading therapy activates areas of the brain necessary for word de-coding.
Researchers may get some indication of how aggressively an angry person will react by measuring the size relationship between a person’s ears and other body parts, according to a new study.
Research showed that the farther certain paired body parts were from symmetry – if one ear, index finger or foot was bigger than another, for example – the more likely it is was that a person would show signs of aggression when provoked. The symmetry effects were different in men and women, howe
Researchers at the University of Arkansas who have been studying the effects of stress on caregivers’ health have found a surprising link between the type of assistance caregivers provide and the amount of stress they report.
“It came as no surprise to us that caregivers are under stress,” remarked Barbara Shadden, director of the program in communication disorders, who, with fellow researcher Ro DiBrezzo, director of the UA Human Performance Lab, serves as co-director of the UA O
A new long-term study finds over 20 years, only one in five women who have mammograms every two years will have to undergo follow up evaluation for a false positive finding. Only one in 16 will have an unnecessary invasive procedure over two decades. The study, published August 23, 2004 in the online edition of CANCER, a peer-reviewed journal of the American Cancer Society, should reassure physicians and patients that the risks of breast cancer screening are minimal given the notable benefit
Since rain and freshwater flooding are the number one causes of death from hurricanes in the United States over the last 30 years, better understanding of these storms is vital for insuring public safety. A recent study funded by NASA and the National Science Foundation offers insight into patterns of rainfall from tropical storms and hurricanes around the world.

Indiana University School of Medicine study published in Science
Blood-making stem cells found in bone marrow, umbilical cord blood and some adult blood products have been used in transplants to treat cancers, leukemia and immune system disorders and to restore blood cell production compromised by chemotherapy and irradiation. But insufficient numbers of donor cells sometime limit success, especially with cord blood transplants.

A study in the August issue of Mayo Clinic Proceedings outlines how strictly controlling the levels of glucose, or sugar, in a patient’s blood can increase the survival rate of critically ill patients.
