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.

Stroke specialists offer guidance on questions about thrombolytic therapy use

One of the most challenging issues in stroke care involves the use of clot-busting drugs such as tPA. When given quickly enough and to the right patient, such drugs can minimize stroke damage by dissolving blood clots that cause most strokes. But these blood-thinning drugs also increase the risk of brain hemorrhages and other complications.

Blocking C5a protein prevents low birth weight in babies born to pregnant women with malaria

An international team of tropical medicine researchers have discovered a potential method for preventing low birth weight in babies born to pregnant women who are exposed to malaria. Low birth weight is the leading cause of infant death globally.

CATT study clarifies value of genetic testing for age-related macular degeneration

New findings from a landmark clinical trial show that although certain gene variants may predict whether a person is likely to develop age-related macular degeneration (AMD), a potentially blinding eye disease that afflicts more than nine million Americans, these genes do not predict how patients will respond to Lucentis- and Avastin-, the two medications most widely used to treat the "wet" form of AMD.

Study questions high rate of cesarean deliveries in women with aneurysms

For women with aneurysms involving the brain blood vessels, pregnancy and delivery don't appear to increase the risk of aneurysm rupture, reports a paper in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Sunitinib shows promise against metastatic renal cell carcinoma

Findings from clinical trial patients with metastatic renal cell carcinoma, a common kidney cancer, show they did not have accelerated tumor growth after treatment with sunitinib, in contrast to some study results in animals. Sunitinib is one of several drugs, either on the market or undergoing testing, that target blood vessel growth.

Positive results from NCI-sponsored bevacizumab trial on cervical cancer

Patients with advanced, recurrent, or persistent cervical cancer that was not curable with standard treatment who received the drug bevacizumab (Avastin) lived 3.7 months longer than patients who did not receive the drug, according to an interim analysis of a large, randomized clinical trial.

Drug-carrying nanoparticles have another hurdle to overcome - escaping the bloodstream

Many medically minded researchers are in hot pursuit of designs that will allow drug-carrying nanoparticles to navigate tissues and the interiors of cells, but University of Michigan engineers have discovered that these particles have another hurdle to overcome: escaping the bloodstream.

Study: 10 to 15% of people with TIAs will experience strokes within three months

Each year, as many as 500,000 Americans experience mini strokes called transient ischemic attacks (TIAs). Symptoms quickly go away, usually within an hour, and many people don't seek treatment. But 10 to 15 percent of people who experience TIAs will experience full-blown strokes within three months, and 40 percent of these strokes will occur in the first 24 hours, according to an article by three Loyola University Medical Center neurologists in the journal Expert Review of Neurotherapeutics.

Patients undergoing major vascular surgery procedures are at increased risk of stroke

Patients undergoing major vascular surgery procedures are at increased risk of stroke, leading to a high mortality rate and prolonged hospitalization, according to a study in the February issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Cloaked nanoparticles escape immune system surveillance to reach desired target

By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying them before they deliver their drug payloads. The group describes its "LeukoLike Vectors", or LLVs, in the January issue of Nature Nanotechnology.

High intensity interval training more suitable to achieve sustainable changes in exercise behaviour

With many of us struggling to get enough exercise, sport and exercise scientists at Liverpool John Moores University (LJMU) and the University of Birmingham, under the lead of Professor Anton Wagenmakers, have been working on a time-saving solution.

Endothelial cells can trigger changes in cancer cells without direct contact

Blood vessels that supply oxygen and nutrients to tumors can also deliver something else - a signal that strengthens nearby cancer cells, making them more resistant to chemotherapy, more likely to spread to other organs and more lethal, scientists at The University of Texas MD Anderson Cancer Center report online in Cancer Cell.

Study expands and deepens biological and genetic links between CVD and schizophrenia

A new study, to be published in the Feb. 7, 2013 issue of the American Journal of Human Genetics, expands and deepens the biological and genetic links between cardiovascular disease and schizophrenia. Cardiovascular disease (CVD) is the leading cause of premature death among schizophrenia patients, who die from heart and blood vessel disorders at a rate double that of persons without the mental disorder.

ADRB receptors play a direct role in Src activation by PKA-mediated mechanism

Scientists at The University of Texas MD Anderson Cancer Center have discovered the signaling pathway whereby a master regulator of cancer cell proteins - known as Src - leads to ovarian cancer progression when exposed to stress hormones. The researchers report in the current issue of Nature Communications that beta blocker drugs mitigate this effect and reduce cancer deaths by an average of 17 percent.

Sanofi introduces LeGoo gel to temporarily stop blood flow during cardiovascular surgery

Sanofi US announced the commercial launch of LeGoo, a biopolymer gel that allows surgeons to temporarily stop blood flow during surgery without the use of clamps, elastic loops or other conventional occlusion devices, which may increase risk of trauma to blood vessels.

Researchers investigate acidity in solid tumors to determine if pH levels play a role in cell invasion

Researchers at Moffitt Cancer Center and colleagues at Wayne State University School of Medicine investigated the acidity in solid tumors to determine if pH levels play a role in cancer cell invasion in surrounding tissues.

Research shows brain cells regulate blood vessel development

Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons.
