Blood vessels deliver nutrients and oxygen to each organ in our body. They are difficult to completely restore to their original conditions once damaged by myocardial infarction or severe ischemic diseases. This is because various angiogenic growth factors must be applied sequentially in order to restore the vascular structure. Recently, a research team at POSTECH […]
Method to derive blood vessel cells from skin cells suggests ways to slow aging
Salk scientists have used skin cells called fibroblasts from young and old patients to successfully create blood vessels cells that retain their molecular markers of age. The team’s approach, described in the journal eLife on September 8, 2020, revealed clues as to why blood vessels tend to become leaky and hardened with aging, and lets […]
AJR study associates COVID-19 with large vessel occlusion strokes
An open-access article published in ARRS’ American Journal of Roentgenology (AJR) investigating the association between coronavirus disease (COVID-19) and stroke subtypes determined that patients with COVID-19 presenting with acute neurologic symptoms warrant a lower threshold for suspicion of large vessel occlusion (LVO) stroke, thus necessitating prompt workup. “To our knowledge, this is the first study […]
Lesion of doom—how a parasitic bacterium induces blood vessel formation to cause lesions
Bacteria of the genus Bartonella are parasites that can be transmitted to humans via insect bites and animal scratches, resulting in an infection known as bartonellosis. Cat-scratch disease and trench fever are forms of bartonellosis caused by different Bartonella species infecting humans. Bartonella bacteria can cause lesions to pop up in the skin and internal […]
Certain Gut Bacteria Tied to Lung Vessel Disease
MONDAY, Feb. 24, 2020 — A specific collection of gut bacteria may be a culprit in the development of pulmonary arterial hypertension (PAH), a new study shows. PAH is a chronic disease marked by the narrowing of arteries that supply blood to the lungs. With constant high blood pressure in these arteries, the right side […]
