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.

Medicine, math and engineering combine to reveal how sepsis and less severe infections occur

It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.

Drug-eluting better than bare metal stents in diabetics

Drug-eluting stents reduced the risk of revascularization, heart attack and death in diabetics as compared with bare-metal stents in the largest observational comparison, researchers reported at the American Heart Association's Scientific Sessions 2008.

New blood test identifies sickest heart failure patients in ER

A new blood test identifies the sickest heart failure patients better than tests now used in emergency departments, researchers reported at the American Heart Association's Scientific Sessions 2008. Results of the Mid-Regional pro-Adrenomedullin (proADM) versus BNP and NTproBNP as Prognosticator in Heart Failure Patients: Results of the BACH Multinational Trial were presented as a late-breaking clinical trial.

Exercise training safe in heart failure patients - offer clinical benefit

Exercise training is safe in heart failure patients, does not significantly reduce hospitalization or death, but is associated with several improved clinical outcomes, even in those already receiving optimal medical care, researchers reported at the American Heart Association's Scientific Sessions 2008. The Heart Failure and A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) was presented as a late-breaking clinical trial.

Stem cells from umbilical cord blood may help build new heart valves

Children with heart defects may someday receive perfectly-matched new heart valves built using stem cells from their umbilical cord blood, according to research presented at the American Heart Association's Scientific Sessions 2008.

Daily rhythms in endothelial cells may explain why heart attacks occur most often in early morning hours

It's not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found.

Chaotic vasculature hinders tumor growth

Dense networks of blood vessels thought to spur cancer's growth could actually hinder rather than promote tumor progression, according to a new study at the University of California, San Diego.

Further evidence that angiogenesis drugs can be much more effective when combined with chemotherapy

Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein.

10 symptoms that should never be ignored

Not every ache and pain merits a quick trip to the doctor -- but some do.

Anti-VEGF drugs for retinal diseases could have serious side effects

Scientists at Schepens Eye Research Institute have found that reducing the levels of vascular endothelial growth factor (VEGF), which is best known as a stimulator of new blood vessel growth, in adult mice causes the death of photoreceptors and Muller glia -- cells of the retina that are essential to visual function.

Stem cell therapies for heart disease - one step closer

New research from the University of Bristol brings stem cell therapies for heart disease one step closer. The findings reveal that our bodies' ability to respond to an internal 'mayday' signal may hold the key to success for long-awaited regenerative medicine.

Systems biology and glycomics used to study human inflammatory diseases

An innovative systems biology approach to understanding the carbohydrate structures in cells is leading to new ways to understand how inflammatory illnesses and cardiovascular disease develop in humans. The work was described in two recent publications by University at Buffalo chemical engineers.

Review of health benefits of grape polyphenols

A growing body of research data suggests that consuming foods rich in polyphenols from grapes - including red wine - helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research.

Exercise-induced fatigue in muscular dystrophies, study points to potential new therapies

A University of Iowa study suggests that the prolonged fatigue after mild exercise that occurs in people with many forms of muscular dystrophy is distinct from the inherent muscle weakness caused by the disease.

Sudden cardiac death number one risk for patients on dialysis

In a 10-year study of more than a thousand kidney failure patients, sudden cardiac death emerged as the number one cause of death for patients on dialysis, according to a Johns Hopkins researcher. The study, already published online and appearing in the Nov. 2 issue of Kidney International, identified systemic inflammatory response and malnutrition as key risk factors for the fatal heart attacks.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

Discovery of 100 new antiangiogenesis peptides

Using computer models and live cell experiments, biomedical engineers at the Johns Hopkins University School of Medicine have discovered more than 100 human protein fragments that can slow or stop the growth of cells that make up new blood vessels.

Targeted nanoparticles map tumor blood supply in 3-D, assess therapy

One of the defining characteristics of solid tumors is the development of a network of new blood vessels to nourish the rapidly reproducing malignant cells. Now, using a nanoparticle targeted to those new blood vessels, a joint academic-industrial research team, led by investigators from the Siteman Center of Cancer Nanotechnology Excellence, has developed a way to construct a three-dimensional (3-D) map of tumor-induced angiogenesis and monitor the effects of drug therapies on those new blood vessels.

Nanotubes detect tumors and deliver high-potency punch

Researchers at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have found a new way to target cancer cells while leaving healthy cells untouched.
