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.

First evidence of blood vessel dysfunction found in healthy young people with cystic fibrosis

The first evidence of blood vessel dysfunction has been found in a small cohort of generally healthy young people with cystic fibrosis, researchers report.

Collaborative research on fruits that may help improve vascular health

Scientists at the University of Warwick and consumer goods manufacturer Unilever are joining forces to identify whether the nutrients in everyday fruit and vegetables could help to improve people's cardiovascular health and protect them from Type-2 diabetes.

New polymer-based system to fight infection, filter water and heal wounds

Working in the lab for the last few years, three generations of University of Akron polymer scientists say their mutual and passionate curiosity about science has led to their discovery of a first-of-its-kind, easily adaptable biocompatible polymer structure able to fight infection, filter water and perform a host of other functions.

KLF4 genetic factor prevents blood vessels from blockages

Researchers at Case Western Reserve University School of Medicine have identified a genetic factor that prevents blockages from forming in blood vessels, a discovery that could lead to new therapies for cardiovascular diseases.

Study: Regular exercise before, during pregnancy could have beneficial effects for women

Contrary to popular thought, regular exercise before and during pregnancy could have beneficial effects for women that develop high blood pressure during gestation, human physiology professor Jeff Gilbert said, summarizing a new study by his research team that appears in the December issue of Hypertension, a journal of the American Heart Association.

Arginine and proline supplementation favor wound healing in diabetic rats

Chronic wounds such as foot ulcers are a common problem for diabetics and are the cause of more than 80 percent of the lower leg amputations in these patients. There is currently no effective way to improve healing of these types of wounds, but new research offers hope.

New insights into how MSCs ‘traffic’ from the circulation into tissues

Mesenchymal stem cells (MSCs), are a newly emerging cellular therapy being tested in approximately 250 clinical trials worldwide to help repair damaged tissues, such as injured heart muscle following a heart attack. The problem is that when culture-expanded MSCs are injected into the circulation, they have trouble gaining access to the inflamed tissues-exactly where their help is needed.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

Diabetics with low vitamin D levels more likely to develop clogged arteries

People with diabetes often develop clogged arteries that cause heart disease, and new research at Washington University School of Medicine in St. Louis suggests that low vitamin D levels are to blame.

Tiltan Pharma initiates enrollment in TL-118 Phase 2 trial for metastatic pancreatic cancer

Tiltan Pharma Ltd. today announced that it has enrolled the first U.S. patient, at White Plains Hospital in Westchester County N.Y., in a Phase 2 clinical trial of its anti-angiogenic product, TL-118, for the treatment of metastatic pancreatic cancer.

Scientists discover how external signals regulate vascular remodelling at cell level

Blood vessels are extremely dynamic: depending on the external conditions, they can adapt their permeability for nutrients, their contractility, and even their shape. Unlike cardiac muscle cells, for example, the smooth muscle cells in blood vessels demonstrate a high degree of plasticity, so they can specialise or multiply as required, even repairing damage to the vessel wall.

Women with migraines do not appear to experience cognitive decline

Women with migraines did not appear to experience a decline in cognitive ability over time compared to those who didn't have them, according to a nine-year follow up study funded by the National Institutes of Health.

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.

Aspirin viable alternative to warfarin in preventing clots after joint replacement surgery

If you've had joint replacement surgery, it's likely you've been given warfarin, a common blood thinner and clot-preventer, prior to surgery. While effective, research from the Rothman Institute at Jefferson has shown aspirin to be just as effective in preventing clots, specifically pulmonary emboli, life-threatening blood clots that can develop in the arteries of the lungs following joint replacement surgery.

Scientists identify group of small molecules that interfere with polyphosphate activity

Scientists have identified a group of small molecules that interfere with the activity of a compound that initiates multiple steps in blood clotting, including those that lead to the obstruction of veins or arteries, a condition called thrombosis. Blocking the activity of this compound, polyphosphate, could treat thrombosis with fewer bleeding side effects than the drugs that are currently on the market.

Geldanamycin degrades VEGFR2 protein that triggers blood vessel growth

The drug, geldanamycin, is well known for attacking a protein associated with the spread of breast cancer. However, a laboratory-based study found it also degraded a different protein that triggers blood vessel growth.

Larger aneurysms linked to greater fluctuations in flow behaviour

Brain aneurysms occur in about six percent of the population. They are dilated sections of blood vessels, which can deteriorate over time until the blood vessel wall ruptures, resulting in a haemorrhage. This causes a loss of mental functions and severe headaches. Haemorrhages of this kind can even be life threatening. The treatment of such patients involves complex medical decision-making. The models developed by Julia Mikhal can be of great use in this regard.

Near-complete blood flow restoration necessary to preserve neurological function following stroke

Two Rhode Island Hospital researchers recently found that restoring near-complete blood flow to the brain is necessary to restore or preserve neurological function following stroke. Seems like a no-brainer, right? Yet until their research was complete, many physicians and researchers believed that partial blood-flow restoration was good enough. Not anymore.

Ischemic stroke: an interview with Dr Gregory Ford

A stroke is a sudden interruption of blood flow to the brain which deprives the brain of oxygen and nutrients. Approximately two millions brain cells die each minute during a stroke. This can lead to brain damage, physical and mental disability and death.
