Researchers develop gene therapy to reverse pulmonary arterial hypertension
A University of Alberta research team has discovered important new information they hope will lead to more effective treatments for pulmonary arterial hypertension (PAH)-a deadly form of high blood pressure in the pulmonary arteries caused by uncontrolled cell growth. view more (2005-06-03)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
Cancer drugs my build and not tear down blood vessels
Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein. But now the opposite seems to be true. view more (2008-11-10)
Gene therapy to lower blood pressure just enough
A newly developed virus that introduces a blood pressure-lowering gene into cells and enables that gene to maintain blood pressure at healthy levels for four months promises to take gene therapy for the disorder a step closer to reality. view more (2005-09-28)
Homing nanoparticles pack multiple assault on tumors
A collaborative team led by Erkki Ruoslahti, M.D., Ph.D., of the Burnham Institute for Medical Research at UC Santa Barbara (Burnham) has developed nanoparticles that seek out tumors and bind to their blood vessels, and then attract more nanoparticles to the tumor target. view more (2007-01-09)
CSHL scientists successfully target tumor microenvironment to stop cancer growth
Cold Spring Harbor Laboratory (CSHL) researchers led by Daniel Nolan and Assistant Professor Vivek Mittal have found that bone marrow (BM) derived endothelial progenitor cells (EPCs) play a critical role in the early stages of tumor progression and that eliminating EPCs stops cancer growth. view more (2007-06-18)
Human vascular system in mice
The formation of new blood vessels, or angiogenesis, is an Achilles' heel of tumor growth, because tumors depend on the supply of oxygen and nutrients for survival. view more (2008-04-15)
Rapamycin shown to inhibit angiogenesis
Scientists have long known that the blood vessels of tumors differ markedly from normal blood vessels. Now, a research team led by scientists at Beth Israel Deaconess Medical Center (BIDMC) has identified a signaling pathway which, when activated, transforms otherwise healthy blood vessels into the leaky, misshapen vasculature that characterizes... view more...

Breakthrough in understanding of blood vessel inflammation
Medical scientists at the University of Leicester have announced a breakthrough in their understanding of blood vessel inflammation - a serious condition which underlies health problems like organ failure in sepsis, the ability to recover from burns, and transplant rejection. The team in the Department of Cardiovascular Sciences at the University... view more... (2004-01-19)
Treat all patients with rare lung disease to prevent stroke, say doctors
Treatment should be offered to all people with a particular rare lung condition, regardless of whether or not they show symptoms of it, say researchers and doctors behind a new study published today. view more (2007-11-05)
Blood vessels might predict prostate cancer behavior
A diagnosis of prostate cancer raises the question for patients and their physicians as to how the tumor will behave. Will it grow quickly and aggressively and require continuous treatment, or slowly, allowing therapy and its risks to be safely delayed? view more (2009-11-04)
Link identified between age, cardiovascular disease
Researchers in the Linus Pauling Institute at Oregon State University have discovered a fundamental mechanism that causes aging blood vessels to lose their elasticity - a literal "hardening of the arteries" that is often a prelude to high blood pressure and cardiovascular disease. view more (2006-11-06)
A missing enzyme conveys major heart protection in pre-clinical work
Mice born without a certain enzyme can resist the normal effects of a heart attack and retain nearly normal function in the heart's ventricles and still-oxygenated heart tissue, according to a study by researchers at Duke University Medical Center. view more (2009-03-31)
Artificial liver for drug tests
If you have hay fever, headaches or a cold, it's only a short way to the nearest chemist. The drugs, on the other hand, can take eight to ten years to develop. view more (2009-06-26)
Tiny molecule helps control blood-vessel development, researchers find
The development and repair of heart tissue and blood vessels is intimately tied to a tiny piece of ribonucleic acid (RNA) that is found nowhere else in the body, researchers at UT Southwestern Medical Center have found. view more (2008-08-13)
St. Joseph's Hospital in Phoenix offers special test for children with stroke risk
Children's Rehabilitative Services (CRS) at St. Joseph's Children's Health Center in Phoenix is using a special ultrasound to identify the risk for stroke in children who have sickle cell disease. view more (2006-01-31)
Bio-engineering of blood vessels
Blood vessel prostheses work best when the biochemical and mechanical properties match reality as much as possible and when they are made of biodegradable material. To this end tissue technologists grow natural vascular wall cells, endothelial cells, in a biodegradable tube made of collagen. According to Professor Istv'¡n Vermes tissue... view more...

Blood-vessel blocker aids cancer-killing virus
Cancer-killing viruses are a promising therapy for incurable brain tumors, but their effectiveness has been limited in part because immune cells rapidly move in and eliminate them. view more (2007-11-28)
New Cancer Treatment Targets Both Tumor Cells and Blood Vessels
It takes more than one punch to fight tumors. Often, tumors have more than one way of surviving, and attacking the tumor alone is not enough. view more (2008-06-19)
Mesh-like Network of Arteries Adjusts to Restore Blood Flow to Stroke-Injured Brain
A grid of small arteries at the surface of the brain redirects flow and widens at critical points to restore blood supply to tissue starved of nutrients and oxygen following a stroke, a study published this week has found. view more (2009-02-02)
