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.

Functional human blood vessels grown in mice using cells from adult human donors

For the first time, researchers have successfully grown functional human blood vessels in mice using cells from adult human donors - an important step in developing clinical strategies to grow tissue, researchers report in Circulation Research: Journal of the American Heart Association.

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.

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 details on how low blood flow promotes vascular disease

Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal Circulation.

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.

Viruses genetically designed to kill cancer cells influence tumor blood-vessel growth

Viruses genetically designed to kill cancer cells offer a promising strategy for treating incurable brain tumors such as glioblastoma, but the body's natural defenses often eliminate the viruses before they can eliminate the tumor.

New perspective on coronary disease thanks to ultrasound

Compared to other techniques, Intravascular Ultrasound (IVUS) is much better at monitoring the increase or decrease of atherosclerosis in the coronary arteries. Can the method even be used to predict the odds of a heart attack or other cardiovascular event? Studies indicate this may be the case, states Professor Clemens von Birgelen in his inaugural address at the University of Twente.
