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.

Researchers reveal how particular melanoma cells help tumors resist drugs

UNC School of Medicine researchers have pinpointed a set of intriguing characteristics in a previously unknown subpopulation of melanoma cancer cells in blood vessels of tumors. These cells, which mimic non-cancerous endothelial cells that normally populate blood vessels in tumors, could provide researchers with another target for cancer therapies.

MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

New treatment strategy may improve repair process after heart attack

In a study that could point the way toward a new strategy for treating patients after a heart attack, UCLA stem cell researchers led by associate professor of medicine (cardiology) and Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research member Dr. Arjun Deb have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells (the cells that form blood vessels).

Researchers discover new kind of stem cell that may hold clues to origins of liver cancer

A Mount Sinai-led research team has discovered a new kind of stem cell that can become either a liver cell or a cell that lines liver blood vessels, according to a study published today in the journal Stem Cell Reports. The existence of such a cell type contradicts current theory on how organs arise from cell layers in the embryo, and may hold clues to origins of, and future treatment for, liver cancer.

Multi-center study compares clinical performance of AAA procedures in virtual environment

University Hospitals (UH) Case Medical Center and Simbionix recently launched a multi-center, randomized study comparing the clinical performance of abdominal aortic aneurysm (AAA) procedures with and without prior rehearsal in a virtual environment for physicians.

New study on global burden of venous thromboembolism

A study on the global burden of venous thromboembolism—when a dangerous clot forms in a blood vessel—found that annual incidences range from 0.75 to 2.69 per 1,000 individuals in the population.

Rockefeller University researchers gain new insight into how cholesterol processes in our body

In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. Manufactured by the cells themselves, it serves to stiffen the cell's membrane, helping to shape the cell and protect it. By mapping the structure of a key enzyme involved in cholesterol production, Rockefeller University researchers and a colleague in Italy have gained new insight into this complex molecular process.

Researchers discover mechanism that leads to generation of new nerve cells after stroke

A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered at Lund University and Karolinska Institutet in Sweden. The findings have been published in the journal SCIENCE.

Women with healthy diet and lifestyle less likely to have stroke

Women with a healthy diet and lifestyle may be less likely to have a stroke by more than half, according to a study published in the October 8, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology.

Minimally invasive valve-repair procedures offer hope for patients who have heart-valve problems

Annie Henderson, 69, suffers from multiple chronic ailments, including kidney failure and mitral valve insufficiency. The later turned her life into a battle for breath, eliminating almost all activities and even making sleep a struggle. She couldn't sleep for more than 20-minutes at a time without waking in a fit of coughing. Thanks to a leading-edge procedure performed at UT Southwestern Medical Center, Mrs. Henderson is now breathing - and sleeping - easy.

Experiments show that 'unsung' cells are crucial to the process of bone loss caused by bone disorder

Experiments in mice with a bone disorder similar to that in women after menopause show that a scientifically overlooked group of cells are likely crucial to the process of bone loss caused by the disorder, according to Johns Hopkins researchers.

UW-Madison and Morgridge researchers are creating tissue chip technology to screen neural toxins

A multidisciplinary team at the University of Wisconsin-Madison and the Morgridge Institute for Research is creating a faster, more affordable way to screen for neural toxins, helping flag chemicals that may harm human development.

Caltech researcher explores link between variable heart rate, health and fitness

Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a "constant" heart rate-and that variability, doctors have found, is a good thing.
