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.

Vascular stabilization biomarker helps optimize timing of anticancer therapies

Angiogenesis, the formation of new blood vessels, is essential for tumor growth. A new study reported in The American Journal of Pathology describes a vascular stabilization biomarker that can visualize blood vessel activity, thus optimizing the timing of anticancer therapies including anti-angiogenics.

Telemedicine enables accurate detection of devastating cause of blindness in premature babies

Accurately detecting a rare, but devastating cause of blindness in premature babies can be done as effectively with telemedicine as with traditional, in-person eye exams, a study published in JAMA Ophthalmology suggests. This is believed to be the first study to directly compare the two approaches.

Aging immune cells increase risk for macular degeneration

As people age, their immune systems age, too. And new research at Washington University School of Medicine in St. Louis suggests that aging immune cells increase the risk for age-related macular degeneration, a major cause of blindness in the United States.

Ionizing radiation can reduce stiffness of tumor cell microenvironment

Nearly half of all cancer patients receive radiation therapy to curb the growth of malignant cells. But little is known about how ionizing radiation affects the extracellular matrix (ECM), a patchwork of proteins and other biomolecules that surrounds cells and plays a vital role in their shape, movement and signaling functions.

Aditlys develops bioresorbable vascular access solution for hemodialysis patients

Aditlys is the first medical technology firm to develop a bioresorbable vascular access solution for patients undergoing dialysis treatment for chronic kidney disease. Aditlys' polymer-based graft enables a patient's body to naturally reconstruct its own blood vessels using the body's own tissue.

Single high-fat meal can set the stage for cardiovascular disease

A single high-fat milkshake, with a fat and calorie content similar to some enticing restaurant fare, can quickly transform our healthy red blood cells into small, spiky cells that wreak havoc inside our blood vessels and help set the perfect stage for cardiovascular disease, scientists report.

Largest-ever study uncovers new genetic contributors to stroke

An international research group, including scientists at the University of Maryland School of Medicine, studying 520,000 people from around the world has identified 22 new genetic risk factors for stroke, tripling the number of gene regions known to affect stroke risk.

Johns Hopkins researchers make great strides in understanding biology behind pulmonary hypertension

Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.

Restoring enzyme may help reverse effects of vascular aging, study shows

As people age, their blood-vessel density and blood flow decrease, which is why it's harder to maintain muscle mass after 40 and endurance in the later decades, even with exercise.

New study identifies key cellular mechanisms behind vascular aging in mice

We are as old as our arteries, the adage goes, so could reversing the aging of blood vessels hold the key to restoring youthful vitality? The answer appears to be yes, at least in mice, according to a new study led by investigators at Harvard Medical School.

New findings could have revolutionary impact on quality of life of older people

Researchers from UNSW and Harvard Medical School have discovered that replacing two naturally occurring molecules in the body could reverse symptoms of aging, potentially influencing how the body responds to and performs exercise.

Patients with vascular malformations have poor health-related quality of life

Patients with vascular malformations, which include blood vessel, artery and lymph vessel abnormalities, appear to have more pain and mental health distress than the general U.S. population and that can contribute to poor health-related quality of life.

Second hand marijuana smoke can cause serious damage

Researchers have shown that even a minute dos second hand marijuana smoke exposure can be dangerous for the blood vessels and raise the risk of several diseases. The study titled “One Minute of Marijuana Secondhand Smoke Exposure Substantially Impairs Vascular Endothelial Function,” was published recently in the Journal of American Heart Association.

Consumption of low-calorie sweeteners could promote metabolic syndrome, increase diabetes risk

Consumption of low-calorie sweeteners could promote metabolic syndrome and predispose people to prediabetes and diabetes, particularly in individuals with obesity, a new study on human fat-derived stem cells and fat samples suggests.

Blacks often have higher air pollution exposure elevating their risk for heart disease, death

Blacks often have higher exposure to air pollution than whites, which may partially explain their higher risk heart disease and death compared to whites, according to new research in Arteriosclerosis, Thrombosis and Vascular Biology, an American Heart Association journal.

Improved methods for capture of circulating tumor cells could help in disease tracking

Tumor cells circulating throughout the body in blood vessels have long been feared as harbingers of metastasizing cancer - even though most free-floating cancer cells will not go on to establish a new tumor.
