Muscle cells on outside of blood vessels wrongly accused for instigating lung disease It turns out the muscle cells on the outside of blood vessels have been wrongly accused for instigating lung disease. New research shows that while these muscle cells are responsible for constricting or dilating the blood vessels, they are not responsible for sensing the amount of oxygen that gets to the lungs. That message comes from the endothelial cells — special cells that line the blood vessels...

By: Katie Williams, Ivanhoe Health Correspondent (Ivanhoe Newswire) — Millions of patients affected by cardiovascular disease need small-diameter blood vessel grafts to help route their blood around blocked arteries. Now, researchers have created a new way to grow healthy, new small-diameter blood vessels from adult stem cells extracted during liposuction. These blood vessels are grown in a lab and could solve large problems associated with grafting blood vessels elsewhere in the...

One of the top suspects behind killer vascular diseases is the victim of mistaken identity, according to researchers from the University of California, Berkeley, who used genetic tracing to help hunt down the real culprit. The guilty party is not the smooth muscle cells within blood vessel walls, which for decades was thought to combine with cholesterol and fat that can clog arteries. Blocked vessels can eventually lead to heart attacks and strokes, which account for one in three deaths in...

Like Yin and Yang, the two proteins have opposite effects in the walls of blood vessels. AIF-1 stimulates undesirable formation of new cells after a vascular injury, and IRT-1 has the opposite effect. It is the latter, IRT-1, that Maria Gomez wants to use to stop a dangerous development in the artery, together with researchers at Lund University Diabetes Centre in Sweden and Temple University in the USA. They have already had success in animal experiments. “After an arterial injury,...

The ambivalent role of the CXCL12/ CXCR4 axis in heart repair The chemokine CXCL12 acts as a chemical signal which mobilizes hematopoietic and other types of stem cells to leave the bone marrow and enter the circulation. Secretion of CXCL12 also guides these cells to sites at which the perfusion of tissue is sub-optimal due to localized obstruction of blood flow. These capabilities have made CXCL12 and its cognate receptor CXCR4 interesting candidates for therapies aimed at mitigating the...

Research at Loyola University Chicago Stritch School of Medicine could help lead to new ways to prevent coronary arteries from reclogging after balloon angioplasties. The latest in a series of studies in this effort is published online ahead of print in Arteriosclerosis, Thrombosis and Vascular Biology, a journal of the American Heart Association. Senior author is Allen M. Samarel, MD, and first author is Yevgeniya E. Koshman, PhD. In an angioplasty, a tiny balloon is inflated to open a...

Researchers at The University of Western Ontario have discovered a strategy for stimulating the formation of highly functional new blood vessels in tissues that are starved of oxygen. Dr. Geoffrey Pickering and Matthew Frontini at the Schulich School of Medicine & Dentistry developed a strategy in which a biological factor, called fibroblast growth factor 9 (FGF9), is delivered at the same time that the body is making its own effort at forming new blood vessels in vulnerable or damaged...

Arteries cultivated from baboon smooth muscle cells contain 20 percent of the protein elastin found in natural arteries, the most reported in vessels grown outside the body, team reports in the Proceedings of the National Academy of Sciences University of Pittsburgh researchers have grown arteries that exhibit the elasticity of natural blood vessels at the highest levels reported, a development that could overcome a major barrier to creating living-tissue replacements for damaged arteries,...

ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS Guidelines Study Highlights:     * New multi-agency guidelines recommend against widespread screening for blocked neck arteries, using ultrasound to detect the condition only in people with symptoms or other stroke risk factors.    * For people with severely narrowed neck arteries, especially when stroke warning symptoms have occurred, either surgery or inserting a stent is a reasonable approach to...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED.
