Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries Long-term brain damage caused by stroke could be reduced by saving cells called pericytes that control blood flow in capillaries, reports a new study led by scientists from UCL (University College London). Until now, many scientists believed that blood flow within the brain was solely controlled by changes in the diameter of arterioles, blood vessels that...

Researchers at Emory and Georgia Tech have developed a potential treatment for atherosclerosis that targets a master controller of the process. The results are scheduled for publication Dec. 18 in the journal Nature Communications. In a twist, the master controller comes from a source that scientists had thought was leftover garbage. It is a micro RNA molecule, which comes from an unused template that remains after punching out ribosomes –– workhorse protein factories found in all...

A new mechanism that regulates the way blood vessels grow and connect to each other has been discovered by an international team of researchers at Karolinska Institutet in Sweden, and Heinrich Heine University Düsseldorf, Germany. The knowledge might open up new opportunities for future cancer therapy. The study is published in the scientific journal PNAS. If stretched out, the blood vessels in a human body would reach more than twice around the earth. The complex circulatory system...

Coating artery-opening stents with a new compound may someday eliminate a common side effect of the treatment, according to preliminary research in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology. Stents are tiny mesh tubes that prop open clogged arteries so blood will flow freely to heart muscle, relieving chest pain and reducing the risk of heart attack. But implanting a stent damages the inner lining of the artery, triggering overgrowth of...

Case Western Reserve University Studies Establish Kruppel-like Factors as Master Regulators of Vascular Health Case Western Reserve researchers have identified a genetic factor that blocks the blood vessel inflammation that can lead to heart attacks, strokes and other potentially life-threatening events. The breakthrough involving Kruppel-like factor (KLF) 15 is the latest in a string of discoveries from the laboratory of professor of medicine Mukesh K. Jain, MD, FAHA, that involves a...

Bioengineered Blood Vessels Successfully Implanted In Patient
2013-06-07 04:50:47

Brett Smith for redOrbit.com - Your Universe Online Surgeons at Duke University have announced the successful implantation of a bioengineered blood vessel in the United States. “This is a pioneering event in medicine,” said Dr. Jeffrey H. Lawson, a vascular surgeon and vascular biologist at Duke Medicine who helped develop the technology. “It´s exciting to see something you´ve worked on for so long become a reality.” “We talk about...

Scientific collaborators from Yale School of Medicine and University College London (UCL) have uncovered the molecular pathway by which new arteries may form after heart attacks, strokes and other acute illnesses bypassing arteries that are blocked. Their study appears in the April 29 issue of Developmental Cell. Arteries form in utero and during development, but can also form in adults when organs become deprived of oxygen – for example, after a heart attack. The organs release a...

Heart disease and approximately half of all strokes are the results of advanced atherosclerosis with damaged endothelium, the inner lining of blood vessels. In 2009, the direct and indirect annual cost of heart disease and stroke was approximately $312.6 billion. Projections are for the total cost of heart disease to increase from $523 to $1.126 billion from 2013 to 2030. And by 2030, it is expected that there will be more than 148 million of the US population would have heart disease....

Life Saving Gel From Mussels
2012-12-12 20:15:56

Lee Rannals for redOrbit.com — Your Universe Online Researchers have created a gel that can be painted onto the walls of blood vessels, which could eventually help save lives. The gel can help to prevent the inflammation that typically occurs when a stent is inserted to widen a narrowed artery or vein. This inflammation often counteracts the opening of the vessel that the stent was intended to achieve. The team wrote about the gel in the current issue of the online journal...
