Johns Hopkins engineers invent lab device that yields microscopic look at metastasis

Johns Hopkins engineers have invented a lab device to give cancer researchers an unprecedented microscopic look at metastasis, the complex way that tumor cells spread through the body, causing more than 90 percent of cancer-related deaths. By shedding light on precisely how tumor cells travel, the device could uncover new ways to keep cancer in check. [More]
UAlberta researchers discover link between pulmonary hypertension, diabetes and cancer

UAlberta researchers discover link between pulmonary hypertension, diabetes and cancer

A UAlberta team has discovered that a protein that plays a critical role in metabolism, the process by which the cell generates energy from foods, is important for the development of pulmonary hypertension, a deadly disease. [More]
University Medical Center's first atrial fibrillation unit opens in Germany

University Medical Center's first atrial fibrillation unit opens in Germany

Nearly 1.8 million people in Germany suffer from atrial fibrillation. This is the most common and clinically significant form of heart rhythm disorder. Shortness of breath, a sudden sense of dizziness, a feeling of pressure in the chest, and palpitations or thumping of the heart so extreme it can be felt beating rapidly and irregularly - this is how many patients describe their first episode of atrial fibrillation.

Researchers reveal how particular melanoma cells help tumors resist drugs

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. [More]
MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

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

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

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. [More]

New study on global burden of venous thromboembolism

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. [More]

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. [More]
Minimally invasive valve-repair procedures offer hope for patients who have heart-valve problems

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. [More]

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

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. [More]
