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

Endothelial progenitor cells may repair leaky blood-brain barrier

University of South Florida Department of Neurosurgery and Brain Repair faculty members have received a $2.6 million grant from the National Institutes of Health to investigate the potential for cells derived from human bone marrow to benefit post-stroke patients by repairing the blood-brain barrier.

Female sex hormone oestrogen could fight against cardiovascular disease

The sex hormone oestrogen could help protect women from cardiovascular disease by keeping the body's immune system in check, new research from Queen Mary, University of London has revealed.

Single engineered protein blocks two related angiogenic receptors

Cancer needs blood. In fact, some cancer medications work solely to slow or prevent cancer cells from creating new capillaries, choking off their much-needed blood and nutrient supply to halt the growth of tumors.

New treatment uses lasers to stimulate stem cells and reduce heart scarring

After a heart attack or stroke, heart scarring can lead to dangerously paper-thin heart walls and a decreased ability to pump blood through the body. Although the heart is unable to completely heal itself, a new treatment developed at Tel Aviv University uses laser-treated bone marrow stem cells to help restore heart function and health.

First bioengineered anal sphincter for treatment of fecal and urinary incontinence

Researchers have built the first functional anal sphincters in the laboratory, suggesting a potential future treatment for both fecal and urinary incontinence. Made from muscle and nerve cells, the sphincters developed a blood supply and maintained function when implanted in mice.

Debate on rationality of coronary angiography in low risk patients continues

A new study reveals that American hospitals vary widely in how they decide who's eligible for an invasive type of heart scan.

Even minor weight loss can improve men’s sex lives: Study

The team of Australian researchers placed 31 obese men with type 2 diabetes on either a meal replacement-based low-calorie diet or a low-fat, high-protein, reduced-carbohydrate diet meant to decrease calorie intake by 600 calories a day. A modest weight loss of 5 percent led to an easing of erectile dysfunction and improved sexual desire within eight weeks, and these improvements continued for 12 months, according to the study published Aug. 5 in The Journal of Sexual Medicine. Problems with urinary tract function also improved, the team added.

New insights into cancer-induced intussusceptive angiogenesis

Researchers have gained a new understanding of the way in which growing tumors are fed and how this growth can be slowed via angiogenesis inhibitors that eliminate the blood supply to tumors. This represents a step forward towards developing new anti-cancer drug therapies.

New method of delivering growth factors could lead to revolutionary heart treatment

Ever since the Nobel Prize for nerve growth factor was awarded more than 30 years ago, researchers have been searching for ways to use growth factor clinically.

Hydrogen sulfide protects blood vessels from diabetes complications

Hydrogen sulfide is a foul-smelling gas with an odor resembling that of rotten eggs. Sometimes called "swamp gas," this toxic substance is generally associated with decaying vegetation, sewers and noxious industrial emissions. And - as odd as it may seem - it also plays a critical role in protecting blood vessels from the complications of diabetes, according to a new study from the University of Texas Medical Branch at Galveston.

MindFrame receives CE mark approval for Capture LP and Flow LP devices

MindFrame Inc. today announces receiving CE mark approval for the MindFrame Capture LP™ and MindFrame Flow LP™ devices. Part of the comprehensive portfolio of MindFrame Therapy Solutions™, these low profile devices can be deployed through a smaller microcatheter to improve access through tortuous vessel anatomies.

Mathematical model predicts progress of tumors from early stages to metastasis

Researchers from the University of Miami (UM) and the University of Heidelberg in Germany have developed a mathematical model to understand and predict the progress of a tumor, from its early stages to metastasis, in hopes of creating highly personalized treatment strategies for patients who have cancer. The findings are published in Nature's new online journal Scientific Reports.

Natural recycling system, PPAR agonists can help protect children with heart defects

Children born with heart defects that pummel their lungs with up to three times the normal blood volume quickly find their lungs in jeopardy as well.

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

Stenting prevents recurrence of aneurysms after minimally invasive 'coiling' procedure

The addition of a simple stent can help prevent potentially lethal blood vessel bulges in the brain from recurring after they are repaired in a minimally invasive "coiling" procedure, according to new research by Johns Hopkins physicians.

UC San Diego receives NHLBI 'Program of Excellence in Glycosciences' grant

Scientists at the University of California, San Diego School of Medicine have received a major 7-year, $18 million grant to begin translating emerging discoveries in the field of glycosciences into new discoveries and therapies related to heart, lung and blood diseases.

Anesthetic agent isoflurane may treat intracerebral hemorrhage

The anesthetic agent isoflurane may be a useful treatment for intracerebral hemorrhage (ICH)—a type of stroke caused by bleeding inside the brain, reports a study in the August issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Researchers identify elusive gene responsible for Grey Platelet Syndrome

Researchers have identified an elusive gene responsible for Grey Platelet Syndrome, an extremely rare blood disorder in which only about 50 known cases have been reported. As a result, it is hoped that future cases will be easier to diagnose with a DNA test.

Rats, fish oil and beetroot juice could lead to health breakthroughs for aging populations

Though rats, fish oil and beetroot juice read like ingredients in a witch's brew, to a Kansas State University research team, information from this combination could lead to health breakthroughs for aging populations and people suffering from heart failure and diabetes.

Scientists find distinct links between smoking during pregnancy and long-term harm for the child

Scientists now understand more about why being exposed to nicotine while you were a fetus will increase your risk of developing cardiovascular disease as an adult. "We have found distinct links between cigarette smoking or even using nicotine patches or gum and the long-term harm for the child," says Dr. DaLiao Xiao, a scientist who works at the Loma Linda University School of Medicine in California.
