Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
University of Alabama at Birmingham biomedical engineers report a significant advance in efforts to repair a damaged heart after a heart attack, using grafted heart-muscle cells to create a repair patch.
Investigators at Case Western Reserve University School of Medicine and University Hospitals Health System have identified a new molecular pathway that controls lifespan and healthspan in worms and mammals.
Despite prevention efforts, researchers have found a significant increase over a 10-year period in the percentage of people with stroke who have high blood pressure, diabetes, smoking and other risk factors for stroke.
Cancer surgeon and researcher Nancy DeMore is leading a clinical trial using frankincense to try to treat breast and colon cancer at the Medical University of South Carolina. The study was inspired by a research specialist in DeMore's lab.
In oxygen-compromising conditions like diabetes, the body grows new blood vessels to help, but the result is often leaky, dysfunctional vessels that make bad matters worse.
Cells lining blood vessels in the lungs that are exposed to bacterial toxins don't die easy, according to a new study led by researchers at the University of Illinois at Chicago College of Medicine.
Researchers at University of California San Diego School of Medicine, with national collaborators, have identified a series of molecular clues to understanding the formation of cerebral cavernous malformations (CCMs).
A new clinical study on the early detection of atrial fibrillation at home is starting at the German Centre for Cardiovascular Research. This cardiac arrhythmia is responsible for a quarter of all strokes and yet the risk of patients with atrial fibrillation having a stroke can be reduced by 70 percent if they take anticoagulants early enough.
UAlberta researchers have created two new imaging agents that could help physicians visualize the formation of tumor-associated blood vessels, keep track of tumor growth and possibly generate new therapies.
In people at higher risk of feeling the cold, and contrary to what scientists thought, beetroot juice doesn't appear to help re-warm the body after exposure to the cold, according to new research.
The U.S. Department of Defense has awarded a team of scientists and physicians from leading health care institutions across Phoenix a $1.3 million grant over three years to study traumatic brain injury and its relationship to dementia.
To win the battle against heart disease, cardiologists need better ways to identify the composition of plaque most likely to rupture and cause a heart attack.
The lungs are one of the last organs to undergo full maturation in a baby's body. Children that are born very prematurely do not have fully developed lungs, and are therefore more susceptible to associated complications.
A minimally invasive procedure used to replace heart valves without open heart surgery appears to provide a durable remedy for people with a life-threatening form of heart disease in which the aortic valve opening narrows, diminishing blood flow.
The first time a young surgeon threads a wire through a stroke victim's chest up through their neck and fishes a blood clot out of their brain may be one of the most harrowing moments in her career.
Transradial catheterization--when a clinician inserts a long thin tube through the radial artery in the arm--is commonly used to diagnose and treat certain heart conditions.
New insights into the development of the vascular system: researchers in the team of Dr Carmen Ruiz de Almodóvar of the Heidelberg University Biochemistry Center have discovered a crucial biological step that regulates the formation of blood vessels.
Preeclampsia may permanently change the blood vessels of women who experience the condition during pregnancy, boosting their lifelong risk for cardiovascular disease, according to Penn State researchers.
In an analysis of published studies, lower levels of alcohol consumption were associated with a lower risk of abdominal aortic aneurysm until approximately 15 to 20 g/day, with an increasing risk thereafter. In the British Journal of Surgery analysis, the increase in risk beyond 2 units/day was stronger in men than in women.
Compounds derived from fire ant venom can reduce skin thickening and inflammation in a mouse model of psoriasis, Emory and Case Western scientists have shown.
