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

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.

Biomedical engineers identify natural switch that controls breast cancer metastasis

With a desire to inhibit metastasis, Cornell biomedical engineers have found the natural switch between the body's inflammatory response and how malignant breast cancer cells use the bloodstream to spread.

IntelliCell receives U.S. patent allowance for ultrasonic cavitation method

IntelliCell BioSciences, Inc. announced that on January 17, 2013 the Company received a notice of allowance regarding its U.S. Patent Application Serial No. 13/323,030 entitled "Ultrasonic Cavitation of Adipose Tissue to Produce Stromal Vascular Fraction Regenerative Cells."

ELTD1 biomarker may help diagnose glioma

Researchers using sophisticated genetic testing techniques have identified a promising new biomarker for diagnosis of glioma—the most common type of malignant brain tumor, reports the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Stem cell transplantation prevents decrease in heart function associated with DMD

Researchers have shown that transplanting stem cells derived from normal mouse blood vessels into the hearts of mice that model the pathology associated with Duchenne muscular dystrophy (DMD) prevents the decrease in heart function associated with DMD.

Mutation that causes sickle cell anemia may offer new way to treat drug-resistant cancers

The genetic mutation that causes sickle cell anemia also turns red blood cells into potent tumor killers and may offer a new way to treat cancers that are resistant to existing treatments, according to research published January 9, 2013 in the open access journal PLOS ONE by David S. Terman of Jenomic Research Institute and colleagues from Duke University and other institutions.

Study highlights role of Protein S in maintenance of healthy retina

Researchers at the Hebrew University of Jerusalem, in collaboration with researchers at the Salk Institute in California, have found for the first time that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular and nervous systems, as well as in various cancers.

Heart attack patients may benefit from mild to moderate sleep-disordered breathing

People who suffer from breathing disorders such as sleep apnea are usually at higher risk for cardiovascular disease. But an intriguing new study from Technion-Israel Institute of Technology scientists suggests that some heart attack patients with these conditions may actually benefit from mild to moderate sleep-disordered breathing.

New insights into devastating second impact syndrome

Physicians at Indiana University School of Medicine and the Northwest Radiology Network (Indianapolis, Indiana) report the case of a 17-year-old high school football player with second impact syndrome (SIS). A rare and devastating traumatic brain injury, SIS occurs when a person, most often a teenager, sustains a second head injury before recovery from an earlier head injury is complete.
