Coronary CTA can be alternative, non-invasive diagnostic imaging test to triage CAD patients: Study

Non-invasive coronary computed tomography angiography is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease, according to a study in the May issue of the American Journal of Roentgenology.

Non-invasive coronary CTA cost-effective alternative to invasive cardiac catheterization for CAD evaluation

According to a study conducted at Thomas Jefferson University (TJU), non-invasive coronary computed tomography angiography (CTA) is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease (CAD). The study will be published in the May issue of the American Journal of Roentgenology.

Magnetically guided nanoparticles for delivering DNA, cells and drugs

Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.

Study underscores potential for VBL Therapeutics VB-111 as broad-spectrum cancer therapy

VBL Therapeutics today announced positive results from preclinical and Phase 1 studies evaluating the company's lead anti-cancer agent, VB-111 - a first-in-class, targeted biological agent shown to work via dual-action, anti-angiogenic and vascular disruptive mechanism of action - in metastatic cancer. Preclinical data evaluating VB-111 in a comprehensive set of in vivo studies employing the Lewis Lung metastasis mouse model showed the compound to be safe and specific, with a 90% reduction in tumor burden of lung metastases after only one injection.

New technique improves cosmetic breast reconstruction in athletic cancer patients

A new technique using tissue from those below-the-waist "love handles" improves cosmetic breast reconstruction in slim, athletic cancer patients without adequate fat sources elsewhere, a small Johns Hopkins study has found. The method also turns out to be less complicated than other options for surgeons as well, the research shows.

Researchers identify gene that appears to increase risk of Alzheimer's disease

Researchers have identified a gene that appears to increase a person's risk of developing late-onset Alzheimer's disease, the most common type of Alzheimer's disease. The research will be presented as part of the late-breaking science program at the American Academy of Neurology's 62nd Annual Meeting in Toronto, April 10 - 17, 2010.

Epilepsy patients who take Ginkgo products face increased risk of seizures: Report

Restrictions should be placed on the use of Ginkgo biloba - a top-selling herbal remedy - because of growing scientific evidence that Ginkgo may increase the risk of seizures in people with epilepsy and could reduce the effectiveness of anti-seizure drugs, a new report concludes. The article appears in ACS' monthly Journal of Natural Products.

Tel Aviv University is bioengineering tissues as an alternative to animal testing

It's illegal for health products with medical formulations to be accepted by the U.S. Food and Drug Administration without tests on animals ― a situation that has serious ethical and moral implications. New research in the field of tissue engineering by Prof. Amit Gefen of Tel Aviv University's Faculty of Engineering holds a promise that far fewer lab animals will be needed for the necessary experimental trials.

Researchers identify major indicator of heart failure and aortic aneurysms

Case Western Reserve University School of Medicine researchers have identified a major indicator of two deadly diseases of the heart and blood vessels: heart failure and aortic aneurysm. The absence of the Kruppel-like Factor 15, when combined with stress, leads to both heart failure and aortic aneurysms.
