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

Scientists design biomaterial that stimulates growth of blood vessels in teeth after root canal

A root canal ranks high on most people's list of dreaded dental procedures. Although the lengthy and sometimes painful surgery relieves the agony of an infection, a root canal results in a dead tooth with no living soft tissue, or dental pulp, inside.

CERENOVUS wins European CE mark approval for BRAVO Flow Diverter to treat intracranial aneurysms

CERENOVUS, part of the Johnson & Johnson Medical Devices Companies, announced today it has received European CE mark approval for its BRAVO Flow Diverter. The device is approved for use in the treatment of patients suffering from intracranial aneurysms.

Wyss researchers create model of the BBB-brain interface using microfluidically linked Organ Chips

The human brain, with its 100 billion neurons that control every thought, word, and action, is the most complex and delicate organ in the body. Because it needs extra protection from toxins and other harmful substances, the blood vessels that supply the brain with oxygen and nutrients are highly selective about which molecules can cross from the blood into the brain and vice versa.

Ultrasound methods could improve early detection of diseases in blood vessels, shows study

Ultrasound conducted before a patient develops symptoms could improve early detection of diseases in blood vessels, research led by the University of Leicester has shown.

Simple leg exercises may prevent heart, blood vessels disease caused by sedentary lifestyle

A sedentary lifestyle can cause an impairment of the transport of blood around the body, which increases the risk of disease in the heart and blood vessels.

Micro-flow model reveals complex interactions between the brain’s blood vessels and nerve cells

Micro-flow models of the blood-brain barrier and the brain reveal for the first time complex metabolic interactions between the brain's blood vessels and nerve cells. The findings are published by an international team of researchers, including from Karolinska Institutet and the Royal Institute of Technology, in the journal Nature Biotechnology.

Texas A&M researchers develop clay-based platform to grow blood vessels

Formation of new blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers from Texas A&M University have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels.

Hospitals battle for control over fast-growing heart-valve procedure

When Medicare in 2011 agreed to pay for a revolutionary procedure to replace leaky heart valves by snaking a synthetic replacement up through blood vessels, the goal was to offer relief to the tens of thousands of patients too frail to endure open-heart surgery, the gold standard.

Scientists explore ways for drug therapies to reach deadly brain tumors

The blood-brain barrier is a specialized network of vascular and brain cells that acts as the brain's security system, helping to safeguard the brain and regulate the flow of substances into and out of it.

Lighter sedation fails to reduce risk of postoperative delirium in older patients

Johns Hopkins Medicine researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair.

Oxidative Stress Hampers Blood Vessel Dilation in Men

Higher levels of oxidative stress in males results in lower levels of cofactor BH needed to make the powerful blood vessel dilator nitric oxide.

Researchers study use of MRI-guided focused ultrasound to open blood-brain barrier

In the first such clinical trial in the United States, physician-scientists with the University of Maryland School of Medicine are investigating the use of MRI-guided focused ultrasound to open the blood-brain barrier.

Compounds in 'monster' radish could potentially prevent heart disease and stroke

Step aside carrots, onions and broccoli. The newest heart-healthy vegetable could be a gigantic, record-setting radish. In a study appearing in ACS' Journal of Agricultural and Food Chemistry, scientists report that compounds found in the Sakurajima Daikon, or "monster," radish could help protect coronary blood vessels and potentially prevent heart disease and stroke.

Physical activity can help reduce risk of heart disease in older adults

Adults in their early 60s, who spend less time sitting and more time engaged in light to vigorous physical activity, benefit with healthier levels of heart and vessel disease markers, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Researchers develop drug-delivery system that allows rapid response to heart attacks

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a drug-delivery system that allows rapid response to heart attacks without surgical intervention.

Nanostructured sensor system offers active monitoring of brain aneurysm treatment

Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms – bulges in blood vessels – but the procedure requires frequent monitoring while the vessels heal.

RBC-hitchhiking method increases concentration of drugs ferried to selected organs

A new drug-delivery technology which uses red blood cells to shuttle nano-scale drug carriers, called RBC-hitchhiking, has been found in animal models to dramatically increase the concentration of drugs ferried precisely to selected organs, according to a study published in Nature Communications this month by researchers from the Perelman School of Medicine at the University of Pennsylvania.
