Rice U. researchers link von Willebrand factor to heart-valve calcium deposits

Heart valves calcify over time, and Rice University scientists are beginning to understand why. The Rice lab of bioengineer Jane Grande-Allen found through studies of pigs' heart valves that age plays a critical role in the valves' progressive hardening, and the problem may be due to the infiltration of a protein known as von Willebrand factor.

Researchers develop new PET tracer to better monitor the progress of cancer and cancer therapy

Researchers develop new PET tracer to better monitor the progress of cancer and cancer therapy

Imaging techniques in cancer medicine provide far more than merely information on the scale and location of cancerous ulcers. There are modern methods that additionally characterise the tumour cells precisely, for instance by specific molecules they carry on their surface. Such additional information gives doctors key clues as to the precise cancer type and enables them to predict the probability that a patient will respond to a particular form of therapy. [More]
DNA fragments in blood may help doctors to quickly identify coronary artery disease

DNA fragments in blood may help doctors to quickly identify coronary artery disease

DNA fragments in your blood may someday help doctors quickly learn if chest pain means you have narrowed heart arteries, according to a new study published in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology. [More]
Th17 lymphocyte: The master coordinator of cellular inflammation in vessel wall

Th17 lymphocyte: The master coordinator of cellular inflammation in vessel wall

Every year, more than 16,000 Americans die as a result of what's known as an "aortic dissection" - a catastrophic rupture of the aorta, the body's largest artery. Once thought to be a simple structural failure, aortic dissection is now understood to be caused by an inflammatory process that weakens the artery's walls. [More]

Men with haplogroup I of Y chromosome have 50% greater risk of developing heart disease

University of Leicester scientists have discovered a potential genetic contributor to the increased risk of heart disease among men. [More]
Study reveals that prolonged Dkk1 signaling can lead to fibrosis, stiffening of artery walls

Study reveals that prolonged Dkk1 signaling can lead to fibrosis, stiffening of artery walls

The hardening of arteries is a hallmark of atherosclerosis, an often deadly disease in which plaques, excessive connective tissue, and other changes build up inside vessel walls and squeeze off the flow of oxygen-rich blood throughout the body. [More]
Breathing motor vehicle emissions triggers change in HDL cholesterol

Breathing motor vehicle emissions triggers change in HDL cholesterol

Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries. [More]
Research: High sugar levels can damage body’s elastic proteins

Research: High sugar levels can damage body’s elastic proteins

High sugar levels in the body come at a cost to health. New research suggests that more sugar in the body could damage the elastic proteins that help us breathe and pump blood. The findings could have health implications for diabetics, who have high blood-glucose levels. [More]

Loyola proposes new subspecialty to diagnose and treat patients with depression, heart disease

A Loyola University Medical Center psychiatrist is proposing a new subspecialty to diagnose and treat patients who suffer both depression and heart disease. He's calling it "Psychocardiology." [More]

German Research Foundation approves funding for Mainz study on cardiovascular disorders

The German Research Foundation has approved funding for the Department of Internal Medicine II of the Mainz University Medical Center to promote the further study of the interrelations between the immune system and cardiovascular system disorders. [More]
Study reveals ugly cholesterol is the direct cause of ischaemic heart disease

Study reveals ugly cholesterol is the direct cause of ischaemic heart disease

The risk of ischaemic heart disease - a disease affecting some 150,000 Danes - is three times higher in persons with high levels of the so-called 'ugly' cholesterol. This is the finding of a new study of 73,000 Danes, which is shedding light on a long debate on this topic. The results have just been published in the Journal of the American College of Cardiology.

Excess vitamin A intake has calcification repercussions

Excess dietary vitamin A intake is significantly associated with increased heart valve calcification, show results from an animal study. [More]
Study illuminates how Aldo and galectin-3 protein contribute to vascular remodeling, CHF

Study illuminates how Aldo and galectin-3 protein contribute to vascular remodeling, CHF

Cardiovascular disease will kill nearly 2.5 million people in the United States this year, according to the Centers for Disease Control. Over time, inflammation, collagen deposition and scar tissue formation can cause blood vessels to stiffen, a process called vascular fibrosis. Though researchers have known that the hormone aldosterone (Aldo) plays a role in this process, the precise mechanisms have been poorly understood. [More]
Tug of war between Hsp70 and 90 determines how much the body makes of superoxide

Tug of war between Hsp70 and 90 determines how much the body makes of superoxide

Two proteins are in a tug of war that determines how much the body makes of superoxide, a highly reactive and potentially destructive product of oxygen that's dramatically elevated in cardiovascular disease, researchers report. [More]
Better understanding of clotting dynamics in atherosclerosis could lead to more effective drugs

Better understanding of clotting dynamics in atherosclerosis could lead to more effective drugs

The disease atherosclerosis involves the build up of fatty tissue within arterial walls, creating unstable structures known as plaques. These plaques grow until they burst, rupturing the wall and causing the formation of a blood clot within the artery. These clots also grow until they block blood flow; in the case of the coronary artery, this can cause a heart attack. [More]
