Experimental radioactive compound can show images of heart damage up to 30 hours after a brief interruption of blood flow and oxygen

The discovery may help physicians in emergency rooms and in their offices determine whether a patient's chest pain, which may have subsided hours earlier, is related to heart disease or something else, such as indigestion.

Cancer vaccine based on the bacterium Listeria monocytogenes, can cure mice with breast tumors

A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors. Cancer vaccines, which are more properly described as immunotherapy, work by boosting an immune response against tumor-associated antigens.

New method to measure circadian cycles

Everyone knows morning people and late-night owls. The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation.

Researchers at Johns Hopkins have identified three new genetic mutations in brain tumors

...a discovery that could pave the way for more effective cancer treatments.

Plans to develop a "universal beta-cell line" - treatment for type 1 diabetes

Transplantation of insulin-producing pancreatic beta-cells shows great promise as a treatment for type 1 diabetes, but development of this therapy has been hampered by a severe shortage of donor beta-cells, which are obtained from decreased human donors.

Discovery of molecule that causes transverse myelitis

Hopkins researchers have discovered a single molecule that is a cause of an autoimmune disease in the central nervous system, called transverse myelitis (TM), that is related to multiple sclerosis.

Statin use associated with a 36 percent reduction in risk of fracture

In a large study of elderly, predominately male veterans, statin use was associated with a 36 percent reduction in risk of fracture when compared with no lipid-lowering therapy, according to a study in the Archives of Internal Medicine

Tumor formation is generated by a complex interaction of both mechanical as well as chemical signals

The relationship between tissue rigidity and tumor formation is fairly well established; however, what is not so well understood is what happens on a molecular level that contributes to such stiffness.

Tobacco industry hindered federal and international regulations on pesticide use

The tobacco industry coordinated cross-industry campaigns to delay and weaken federal and international regulations on pesticide use, according to new findings by University of California - San Francisco (UCSF) researchers.

Chronically high levels of insulin may block specific hormones that trigger energy release into the body

Their findings, which may point to new approaches to developing improved treatment options for the disease, are published in the journal Nature.

Adults not washing hands

Ninety-one percent of American adults say they always wash their hands after using public restrooms. But just 83 percent actually did so, according to a separate observational study.

85 percent of postmenopausal women do not get enough calcium

An analysis presented today at the 27th Annual Meeting of The American Society for Bone and Mineral Research found that 85 percent of postmenopausal women do not get enough calcium on a daily basis.

Extreme gene pin-pointed

One teenager likes to snowboard off a cliff. Another prefers to read a book and wouldn't think of trading places. Why these differences exist is a mystery, but for the first time researchers have identified a possible genetic explanation behind risk-seeking behavior.

Mutations in receptor tyrosine kinases provide potential for highly-targeted cancer therapies

Scientists from J. Craig Venter Institute, Ludwig Institute for Cancer Research, and The Johns Hopkins University School of Medicine identified three novel mutations in two receptor tyrosine kinases in glioblastoma tumors using high throughput sequencing.

State-of-the-art treatment program increases survival from the aggressive uterine papillary serous carcinoma

"Our study defines a standard of care for this aggressive and growing form of uterine cancer," said Schwartz, who is also assistant chief of obstetrics and gynecology at Yale-New Haven Hospital. The procedure more accurately determines the complete stage and appropriate treatment and reduces the recurrence of the cancer.

Surprising immune system cells discovery

Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells.

Increasingly virulent Staph infections

In a "Brief Report" in the 22 September 2005 issue of the New England Journal of Medicine, researchers at the University of Chicago describe three cases of rapidly progressive and ultimately fatal Staphylococcus aureus infections in small children.

Researchers have found a way to keep students awake during class

Whether it's triggered by the monotone of an instructor or insufficient rest the night before, students at all ages and grade levels sometimes have trouble staying awake in class.

Heart attack patients run an increased risk of developing post-traumatic stress disorder

This may lead to a vicious cycle, with the PTSD associated with heart disease harming the patient's future cardiac heath, according to the study in the current issue of Psychosomatic Medicine.

Aggressive public health efforts to control hypertension may help preserve cognitive abilities as well as cardiovascular health

Not only does high blood pressure adversely affect mental functioning, but the correlation appears to be stronger among African-Americans than among whites, researchers report in the current issue of Psychosomatic Medicine.
