The first medical research paper submitted from the International Space Station (ISS) was published online today by the journal Radiology. The report documents the first ultrasound examination of the shoulder performed under the microgravity conditions of space flight.
Members of Expedition 9 crew aboard the ISS completed the study as part of the Advanced Diagnostic Ultrasound in Microgravity (ADUM) experiment. “It is with great pleasure that we offer to the journal Radiology the
Lycopene, an antioxidant commonly found in tomatoes and tomato-based products, is commonly perceived to reduce the risk of developing prostate cancer.
A new study at Northwestern University seeks to determine whether natural tomato oil with a high concentration of lycopene may reverse or delay progression of high-grade prostatic intraepithelial neoplasia (HGPIN), a condition in which abnormal cells form within the prostate and which is the strongest risk factor yet identified fo
Rice U. geologists probe impact of rising seas along US Gulf Coast
New research presented at this week’s annual meeting of the Geological Society of America shows that rising sea levels of as little as a half-meter per century have been sufficient to dramatically change the shoreline of the U.S. Gulf Coast within the past 10,000 years. The findings are significant because half-meter increases are within the moderate range of predictions for the Gulf Coast during this century.
Researchers at New York University’s Courant Institute of Mathematical Sciences have developed a new algorithm that can lead to more accurate detection of cancer genes than previous versions. The algorithm, published in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), can also be applied to the multiple biomedical technologies (e.g., different kinds of micro-arrays) used to analyze cancer patients’ genomes.

Many heart disease patients who are already receiving state-of-the-art therapy do not benefit from additional treatment with angiotensin converting enzyme (ACE) inhibitors, according to results of a new study funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. The study provides the most definitive evidence to date of the effect of the drug in stable heart disease patients whose heart function was shown to be at normal or near-normal levels
Fibrin gel matrix-based vessel ready for test transplantation after only two weeks in culture
The search for a stable, renewable source of blood vessels, especially for potential use in heart bypass surgery, has reached a milestone at the State University of New York at Buffalo. A multi-disciplinary team at SUNY Buffalo designed tissue engineered blood vessels (TEVs) using a matrix of vascular smooth muscle embedded in fibrin gels. After only two weeks in culture, the TEVs show
Patients who suffer a loss of cognitive and motor function as a result of stem cell transplantation for severe blood disorders are likely to see those functions return to previous levels after one year, according to a new study in the November 15, 2004, issue of Blood, the official journal of the American Society of Hematology.
Researchers from the Fred Hutchinson Cancer Research Center and the University of Washington School of Medicine studied 142 patients who had blood disorders, such as
Global warming has forced U.S. plants and animals to change their behavior in recent decades in ways that can be harmful, according to a new report prepared for the Pew Center on Global Climate Change.
The Pew Center review of more than 40 studies is co-authored by Camille Parmesan, integrative biologist at The University of Texas at Austin, and Hector Galbraith of Galbraith Environmental Services, who is affiliated with the University of Colorado at Boulder. Their analyses revea
Reviparin is simple, effective therapy for heart attack patients worldwide
A major Canadian-led global study has found that an inexpensive anti-blood-clotting drug significantly reduces death and repeat heart attacks without increasing the risk of stroke. The study is of significance to patients in all countries, including developing countries where access to high-tech treatments for cardiovascular problems may be limited.
The CREATE randomized trial was initiated and c
A new magnetic navigation system shows promise for use during percutaneous coronary interventions (PCI), researchers reported at the American Heart Association’s Scientific Sessions 2004.
“The computer-controlled magnetic system is useful to steer guide wires and navigate turns in tortuous coronary arteries that would otherwise be impossible to negotiate,” said study co-author Neal S. Kleiman, M.D., director of cardiac catheterization laboratories at the Methodist DeBakey
In experiments with pigs, scientists at Johns Hopkins have successfully used a technique called “gene painting” to target gene therapy to a specific region of the heart and change the heart’s rhythm.
“Getting the genes where we want them has been a key limiting factor in the successful development of gene therapies for heart conditions,” said cardiac electrophysiologist Kevin Donahue, M.D., an associate professor at The Johns Hopkins University School of Medicine and its H
Genetically modified (GM) corn won’t threaten native corn species in Mexico, according to a new report issued by the North American Free Trade Association (NAFTA).
In a country whose culture and identity revolve heavily around corn, or maize – the crop was first developed here thousands of years ago – the thought of imported GM varieties contaminating indigenous plants frightens many citizens, said Allison Snow, a co-author of the report and a professor of evolution, ecology
Cath lab procedure could replace major heart surgery in some patients
The Hospital of the University of Pennsylvania (HUP) is participating in a nationwide clinical trial of a new valve repair device that could replace major heart surgery in some patients. A tiny clip – delivered by a catheter and deployed in the heart to repair a malfunctioning and leaking mitral valve – is building a favorable safety and feasibility profile as the EVEREST Phase I clinical trial nears completion.
A Penn State study has shown that a diet rich in alpha-linolenic acid from walnuts, walnut oil and flaxseed oil not only lowered bad cholesterol but also decreased markers for blood vessel inflammation in men and women representative of typical Americans at cardiovascular risk.
While previous studies have shown that walnut supplementation favorably affects cholesterol and other lipids that are signs of cardiovascular risk, this new study is the first to demonstrate that a diet
Patients who undergo coronary artery bypass surgery are prescribed life-saving medications at discharge significantly less frequently than heart attack patients who receive less invasive angioplasty procedures, according to a new analysis by researchers at the Duke Clinical Research Institute.
These findings are important, the researchers said, because the drugs in question — aspirin, ACE inhibitors, beta blockers and statins — have been proven effective by multi-center clinical
A new study gives people in their 50s and 60s another reason to get off the couch and be physically active — especially if they have conditions or habits that endanger their hearts, like diabetes, high blood pressure or smoking.
The study, based on data from 9,611 older adults, shows that those who were regularly active in their 50s and early 60s were about 35 percent less likely to die in the next eight years than those who were sedentary. For those who had a high heart risk be
