(Medical Xpress)—The endothelium, the cellular layer lining the body's blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body's circulatory system. http://medicalxpress.com/news/2013-05-endothelium-thyself-fresh-resilient-tissue.html Medical research Thu, 16 May 2013 06:58:10 EST news287906284 Researchers from Boston University School of Medicine (BUSM) have shown that using magnetic resonance imaging (MRI) to measure blood flow over atherosclerotic plaques could help identify plaques at risk for thrombosis. The findings, which appear in the March issue of Circulation: Cardiovascular Imaging, offer a non-invasive application in the diagnosis and treatment of patients with atherosclerosis. http://medicalxpress.com/news/2013-04-mri-blood-atherosclerotic-plaque-dangerous.html Cardiology Fri, 05 Apr 2013 13:15:07 EST news284386406 The answer to longevity may be far simpler than we imagine; it may in fact be right under our noses in the form of a morning caffeine kick. The elderly inhabitants of Ikaria, the Greek island, boast the highest rates of longevity in the World, and many scientists turn to them when looking to discover the 'secrets of a longer life'. In a new study in Vascular Medicine researchers investigating cardiovascular health believe that a cup of boiled Greek coffee holds the clue to the elderly islanders' good health. http://medicalxpress.com/news/2013-03-greek-coffee-key-longer-life.html Health Mon, 18 Mar 2013 13:39:51 EST news282832749 Hydrogen sulfide (H2S) may play a wide-ranging role in staving off aging, according to a paper published online ahead of print in the journal Molecular and Cellular Biology.

The problem is that when culture-expanded MSCs are injected into the circulation, they have trouble gaining access to the inflamed tissues—exactly where their help is needed. http://medicalxpress.com/news/2012-11-reveals-insights-aid-therapeutic-mesenchymal.html Medical research Thu, 15 Nov 2012 13:12:21 EST news272207529 A single junk food meal – composed mainly of saturated fat – is detrimental to the health of the arteries, while no damage occurs after consuming a Mediterranean meal rich in good fats such as mono-and polyunsaturated fatty acids, according to researchers at the University of Montreal-affiliated ÉPIC Center of the Montreal Heart Institute. The Mediterranean meal may even have a positive effect on the arteries. The findings are being presented at the Canadian Cardiovascular Congress, which runs in Toronto until Wednesday, by the head of the study, Dr. Anil Nigam, Director of Research at the Cardiovascular Prevention and Rehabilitation Centre (ÉPIC) and associate professor at the university's Faculty of Medicine. http://medicalxpress.com/news/2012-10-reveals-junk-food-meal-arteries.html Health Tue, 30 Oct 2012 11:50:11 EST news270816034 UCLA stem cell researchers have found for the first time a surprising and unexpected plasticity in the embryonic endothelium, the place where blood stem cells are made in early development. http://medicalxpress.com/news/2012-08-embryonic-blood-vessels-stem-cells.html Medical research Thu, 02 Aug 2012 12:00:16 EST news263127566 Acute inflammatory diseases, such as sepsis, as well as chronic inflammatory diseases like diabetes and arthritis, develop as a result of sustained inflammation of the blood vessel wall.
