Blood Vessel News and Research

RSS

Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

MicroRNAs help control blood-vessel development

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.

Scientists identify microRNA that controls blood vessel development - therapeutic target for a number of diseases

Scientists from the Gladstone Institute of Cardiovascular Disease (GICD) and UCSF have identified a key regulatory factor that controls development of the human vascular system, the extensive network of arteries, veins, and capillaries that allow blood to reach all tissues and organs.

Link between small birth size and changes to the CV system that predispose to disease in later life

Researchers have found the first evidence that smaller size at birth is associated with specific alterations in the functioning of the heart and circulation in children and that these changes differ between boys and girls.

New therapies revealed for diabetes-induced microvascular disease

New findings from Bristol scientists could lead to future treatments to prevent lower limb amputations in diabetes - which currently affect 100 people a week in the UK (source Diabetes UK). The research from the University of Bristol is published online in Circulation Research and was funded by the British Heart Foundation (BHF) and the European Vascular Genomic Network of Excellence (EVGN).

Scientists reveal key elements in Malaria parasite's "sticky sack" adhesion strategy

Malaria is one of the most devastating diseases afflicting humanity. It infects and debilitates about 600 million people and kills up to three million people every year, mainly in the wet tropical regions of the world. Children and pregnant women are at particularly high risk.

How alcohol impacts heart and stroke risk may differ for men and women

The volume of alcohol consumption may have a significantly different effect on heart and stroke risk in men and women, according to a study of Japanese people published in Stroke: Journal of the American Heart Association.

Nanomaterials key to new strategies for blocking metastasis

A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue, according to a collaborative team of researchers at the Center of Nanotechnology for Treatment, Understanding, and Monitoring of Cancer at the University of California, San Diego. In designing this system, the investigators, led by David Cheresh, Ph.D., have identified what may become a generic method for using nanotechnology to target metastasis.

93-year old man with life threatening aneurysm treated using new fenestrated endograft stent

In a New York City metro-area first, a 93-year-old Bronx man underwent implantation of a new stent graft at NewYork-Presbyterian Hospital, the only center on the Eastern Seaboard with access to this investigational device. The new stent graft was implanted under an FDA-approved clinical trial protocol.

Drug-releasing coronary artery stent use linked with decrease in procedures to unblock coronary arteries

The widespread adoption of the use of drug-releasing coronary artery stents into routine practice is associated with a decrease in the need for repeat procedures to unblock coronary arteries and also do not appear to increase the risk of death, compared to bare-metal stents, according to a study in the June 25 issue of JAMA, the Journal of the American Medical Association

New approach for assessing and managing patients with sepsis

Each year over a million people suffer from sepsis, a condition caused by an infection spreading through the body. If sepsis develops into severe sepsis then the death rate can rise to nearly 30 - 50%, equalling the number of deaths caused by a heart attack.

Adult stem cells improve healing of broken bones

Adult stem cells improve healing of broken bones and could eventually serve as a new treatment for the 10 to 20 percent of fractures that fail to heal, according to a new study. The results were presented Monday, June 16, at The Endocrine Society's 90th Annual Meeting in San Francisco, by Froilan Granero-Molto, PhD, research associate of the University of North Carolina.
