Single Chip Device to Provide Real-Time 3-D Images from Inside the Heart and Blood Vessels

Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart, and potentially allow more of patients’ clogged arteries to be cleared without major surgery. ...

New approach prevents thrombosis without increasing the risk of bleeding

In collaboration with an international team, researchers at Karolinska Institutet have developed an antibody, 3F7, which blocks a protein that is active in the coagulation system factor XII. Inhibition of factor XII makes it possible to prevent thrombosis in blood vessels without increasing the risk of bleeding in clinical settings. ... Full story

Here comes the sun – How vitamin D relaxes blood vessels

It’s not just your mood that the dark months of winter can influence. Low levels of sunlight also mean lower levels of vitamin D in the body. Vitamin D deficiency can trigger a range of diseases but until recently little was known about the exact biological mechanisms behind this. A research team at the University of Veterinary Medicine, Vienna has now decrypted one of these unknown molecular mechanisms. ... Full story

Study Sheds Light On Risk of Life-Threatening Blood Clots in Hospitalized Children

Life-threatening blood clots occur so rarely in children that the condition, known as venous thromboembolism (VTE), is often not on pediatricians' mental radar screens - an absence that can lead to woefully delayed recognition and treatment. ... Full story

Partially Blocking Blood Vessels’ Energy Source May Stop Cancer Progression, Blindness, and Other Conditions

Inhibiting the formation of new blood vessels is a common strategy for treating a range of conditions such as cancer, inflammatory diseases, and age-related macular degeneration. Unfortunately, drug inefficiency, resistance, and relapse have limited the success of this approach. Now new research publishing online December 12 in the Cell Press journal Cell Metabolism reveals that targeting the metabolism of blood vessels may be a way around these shortcomings. ... Full story

Hybrid clotting factor means fewer injections, better disease control for hemophilia patients

(SACRAMENTO, Calif.) — A Phase III clinical trial led by UC Davis researchers has confirmed that a new coagulation factor (rFIXFc) dramatically reduces the number of injections needed to maintain effective clotting for hemophilia B patients. ... Full story
