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

Molecule Thymosin beta-4 prompts damaged heart cells to repair themselves after a heart attack

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found.

Growth factor TGF-beta helps maintain health of retinal blood vessels

Scientists at Schepens Eye Research Institute have found that the growth factor known as TGF-beta is essential to the health of blood vessels in the retina and that blocking it can cause retinal dysfunction.

Inflammatory chemokine may explain diseases that come with obesity

An inflammatory factor already linked to several diseases, including pulmonary disease, lung cancer, and arthritis, may also be responsible for the insulin resistance that comes with obesity, according to a new study published in the April issue of Cell Metabolism.

Stem cells from bone marrow used to grow new blood vessels

Research led by David Hess of the Robarts Research Institute at The University of Western Ontario has identified how to use selected stem cells from bone marrow to grow new blood vessels to treat diseases such as peripheral artery disease.

'Pre-diabetics' face heightened risk of heart disease

The study, published in the Journal of Clinical Endocrinology & Metabolism , was led by Jill P. Crandall, M.D., associate professor of clinical medicine and director of the Diabetes Clinical Trials Unit at Einstein.

Study looks at long-term benefits of the Wingspan stent

Rush University Medical Center is participating in a National Institutes of Health (NIH) study to determine the best course of treatment to reduce the risk of stroke patients suffering another stroke.

New streamlined triage system for "brain attack"

Taking a page out of the playbook developed by cardiologists nearly two decades ago to promote the warning signs and swift treatment for heart attacks, a multidisciplinary team of stroke experts at the University of Rochester Medical Center (URMC) have created a new streamlined triage system at Strong Memorial Hospital's Emergency Department (ED) to provide rapid evaluation and specialized treatments to "brain attack," or stroke, patients.

Protein ferritin in blood may hold key to stopping tumor growth in cancer patients

A recent discovery by researchers at Wake Forest University School of Medicine could clear the way for a new drug that inhibits tumor growth in cancer patients and could potentially help in the healing of wounds.

Missing enzyme GNSOR conveys major heart protection in pre-clinical work

Mice born without a certain enzyme can resist the normal effects of a heart attack and retain nearly normal function in the heart's ventricles and still-oxygenated heart tissue, according to a study by researchers at Duke University Medical Center.

Angiogenesis inhibitor improves glioblastoma survival by reducing edema

The beneficial effects of anti-angiogenesis drugs in the treatment of the deadly brain tumors called glioblastomas appear to result primarily from reduction of edema - the swelling of brain tissue - and not from any direct anti-tumor effect, according to a study from Massachusetts General Hospital (MGH) researchers.

Dapagliflozin trial results indicate improvement in key glycemic measures in treatment-naive type 2 diabetes

Findings published in Diabetes Care from a 12-week, Phase IIb dose-ranging study showed that dapagliflozin, a novel, selective, sodium glucose co-transporter2 (SGLT2) inhibitor, produced clinically meaningful reductions across all key glycemic measures studied [glycosylated hemoglobin level (HbA1c), fasting plasma glucose (FPG), and postprandial plasma glucose (PPG)] in treatment-naive type 2 diabetes patients, compared to placebo.

Aspirin decreases first heart attacks in men and first strokes in women

Patients and clinicians should consider risk factors -- including age, gender, diabetes, blood pressure, cholesterol levels, smoking and risk of gastrointestinal bleeding -- before deciding whether to use aspirin to prevent heart attacks or strokes, according to new recommendations from the U.S. Preventive Services Task Force.

Risks of using aspirin to prevent heart attack or stroke differ by gender and age

Patients and clinicians should consider risk factors-- including age, gender, diabetes, blood pressure, cholesterol levels, smoking and risk of gastrointestinal bleeding-- before deciding whether to use aspirin to prevent heart attacks or strokes, according to new recommendations from the U.S. Preventive Services Task Force.

Disparities in stroke outcomes between black and white patients still great

In Florida, black young adults are hospitalized for stroke at a rate three times higher than their white and Hispanic peers, a new study by University of South Florida researchers reports.

Shining light on diabetic retinopathy

A group of scientists in California is trying to develop a cheaper, less invasive way to spot the early stages of retinal damage from diabetic retinopathy, the leading cause of blindness in American adults, before it leads to blindness.

Saving limbs with drug-eluting stents

Attempts to treat critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty are still thwarted by restenosis (the re-narrowing of the artery at the site of angioplasty or stenting), the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death (gangrene) and amputation.

Interventional radiology makes complicated C-sections safer

Innovative, interventional radiology treatments are making childbirth safer for women who have C-sections that are complicated by massive bleeding and for those who suffer from the pregnancy condition of "invasive" placenta.

Interventional treatment can be recommended as first-line treatment for 'silent killer'

Endovascular or endograft repair, a minimally invasive interventional radiology treatment that uses stent grafts to treat abdominal aortic aneurysms (AAA), has low re-intervention rates that are comparable to those reported for open surgical repair-and can be recommended as first-line treatment, according to a study released at the Society of Interventional Radiology's 34th Annual Scientific Meeting.

Pulmonary hypertension in children may result from reduced activity of gene regulator

Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say.
