Spleen cells may do more harm than good at site of spinal cord injury

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

Pericyte cells become key players in shaping blood flow in the brain

Cells in the brain called pericytes that have not been high on the list of targets for treating diseases like Alzheimer's may play a more crucial role in the development of neurodegenerative diseases than has been realized.

Cholesterol-lowering statin therapy benefits patients with calcium buildup in arteries

Rolling back suggestions from previous studies, a Johns Hopkins study of 950 healthy men and women has shown that taking daily doses of a cholesterol-lowering statin medication to protect coronary arteries and ward off heart attack or stroke may not be needed for everyone.

Perivascular adipose tissue may lead to cardiovascular disease: Research

Researchers at the University of Cincinnati (UC) have found that fat around the outside of arteries may lead to the development of cardiovascular disease and could be linked to its onset in individuals with diabetes.

Combination of CT scans effective in diagnosing coronary artery disease

Heart imaging specialists at Johns Hopkins have shown that a combination of CT scans that measure how much blood is flowing through the heart and the amount of plaque in surrounding arteries are just as good as tests that are less safe, more complex and more time-consuming to detect coronary artery disease and its severity.

Stem cells for stroke: Clinical trial commences

Researchers have started the world’s first clinical trial of stem cells to treat stroke victims in Glasgow. The trial is undertaken by ReNeuron, a Guildford-based biotech company and started this weekend with an elderly man receiving an injection of 2 million stem cells into his brain. It received final approval to go ahead this year.

UC San Diego researchers receive NIH grant to develop scaffolds

University of California, San Diego NanoEngineers won a grant from the National Institutes of Health (NIH) to develop the tools to manufacture biodegradable frames around which heart tissues functional blood vessels included will grow.

New stem cell-infused patch improves heart function after myocardial infarction

University of Cincinnati (UC) researchers have found that applying a stem cell-infused patch together with overexpression of a specific cell instruction molecule promoted cell migration to damaged cardiac tissue following heart attack and resulted in improved function in animal models.

Iron in plaque may predict risk of myocardial infarction

Plaque in a heart artery looks threatening, but cardiologists know that many of these buildups will not erupt, dislodge and block a vessel, causing a heart attack that can be fatal. Some will, however, and the challenge is to figure out atherosclerotic plaque that is dangerous and treat or remove it.

Research suggests targeting spleen may promote healing of spinal cord injury

The spleen, an organ that helps the body fight infections, might also be a source of the cells that end up doing more harm than good at the site of a spinal cord injury, new research suggests.

Sangart's MP4CO receives orphan drug designation for acute pain in sickle cell disease

Sangart, Inc., a global biopharmaceutical company dedicated to developing life-saving medicines specifically designed to enhance the perfusion and oxygenation of ischemic (oxygen deprived) tissues through targeted oxygen and other gas delivery, today announced that its investigational biopharmaceutical product, MP4CO, has been awarded orphan drug designation by the U.S. Food and Drug Administration (FDA) for use in treating acute painful sickling crises in patients with sickle cell disease.

New protocol reduces radiation exposure in pediatric electrophysiology procedures

A protocol that uses continuous real-time radiation monitoring, low-dose imaging programs and requires physician awareness of radiation dose, significantly reduced radiation exposure during electrophysiology procedures and catheter ablations to diagnose and treat heart arrhythmias in children, according to research presented at the American Heart Association's Scientific Sessions 2010.

Oregon scientist investigates safety, effectiveness of novel low-cost family-planning option

The Bill & Melinda Gates Foundation has awarded nationally prominent Oregon Health & Science University reproductive scientist Jeffrey T. Jensen, M.D., M.P.H., a $100,000 grant to investigate the safety and effectiveness of a novel low-cost family-planning option that may be applicable to women in low-resource countries worldwide.

Scientists unveil mechanism of liver regeneration

The liver's unique ability among organs to regenerate itself has been little understood. Now Weill Cornell Medical College scientists have shed light on how the liver restores itself by demonstrating that endothelial cells the cells that form the lining of blood vessels play a key role.

GPR124 protein controls growth of blood vessels into brains

One protein single-handedly controls the growth of blood vessels into the developing brains of mice embryos, according to researchers at the Stanford University School of Medicine. Understanding how the protein, a cellular receptor, functions could help clinicians battle brain tumors and stroke by choking off or supplementing vital blood-vessel development, and may enhance the delivery of drugs across the blood-brain barrier.

New catheter device for abdominal aortic aneurysm

William E. Sorfleet had a life-threatening abdominal aortic aneurysm, but at age 82, he was too old for major invasive surgery to repair the bulging blood vessel. So vascular surgeon Dr. Ross Milner of Loyola University Hospital repaired the aneurysm with a catheter device instead of a scalpel. The catheter, inserted through an artery, deployed a device called a stent graft that repaired the aneurysm.
