- Novel method enables genomic screening of blood vessels from patient tissue
08-28-2007 · EurekAlert!
Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

- New hope for regenerative medicine
02-14-2007 · EurekAlert!
In the February 15th issue of Genes & Development, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. Uniparental embryonic stem cells are an appealing alternative source of patient-derived embryonic stem cells, as they have several advantages over embryonic stem cell lines generated by somatic cell nuclear transfer (also known as therapeutic cloning).

- Blood's clotting cells harbor 'ticking time bombs,' finding may help extend blood supply
03-22-2007 · EurekAlert!
Fragments of cells in the blood known as platelets—which form blood clots and assist in wound healing—have internal 'clocks' that act like ticking time bombs, predetermining their death from the moment they are born, according to a new study in the March 23 issue of the journal Cell, published by Cell Press.

- New study shows promise in reducing surgical risks associated with surgical bleeding
08-10-2007 · EurekAlert!
Surgeons may have a new patient safety tool to stop moderate surgical bleeding without some of the concerns associated with the current standard blood-clotting treatment. New research published in the August issue of the Journal of the American College of Surgeons shows that recombinant human thrombin (rhThrombin) reduces the risk of surgical complications associated with the use of plasma-derived bovine thrombin (bThrombin), which is currently the only commercially available stand-alone thrombin used to improve clotting during surgical procedures and stop bleeding.

- Exploring the molecular origin of blood clot flexibility
01-12-2007 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine and the School of Arts and Sciences have shown that a well-known protein structure acts as a molecular spring, explaining one way that clots may stretch and bend under such physical stresses as blood flow. This knowledge will inform researchers about clot physiology in such conditions as wound healing, stroke and cardiovascular disease.

- New angioplasty procedure proving more effective
11-14-2006 · EurekAlert!
Over the last several years angioplasty has exceeded coronary bypass surgery as the preferred way to treat coronary artery disease. The stents, narrow tubes inserted into the artery to facilitate blood flow, commonly used in the procedure are less invasive than open-heart surgery and offer greater convenience to the patient and the ability to perform more complex procedures.

- A type of antioxidant may not be as safe as once thought
09-04-2007 · EurekAlert!
According to new research at the University of Virginia Health System, N-acetylcysteine (NAC), an antioxidant commonly used in nutritional and body-building supplements, can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen. This leads to pulmonary arterial hypertension (PAH), a serious condition characterized by high blood pressure in the arteries that carry blood to the lungs.

- Gene variations associated with effectiveness of blood pressure medications
01-22-2008 · EurekAlert!
Patients with hypertension and certain gene variations experienced varying results with some blood pressure medications, suggesting matching a patient's genotype with certain hypertension medications could result in more favorable outcomes, according to a study in the Jan. 23 issue of JAMA.
