CHEST, HEART AND STROKE SCOTLAND FUND CORONARY BALLOON ANGIOPLASTY RESEARCH
Chest, Heart and Stroke Scotland have awarded a grant of £28,865 to support the work, which will look at the part played by angioplasty balloon pressure in the sudden closure of blood vessels. Subsequent problems for the patient can include heart attack and/or emergency coronary bypass surgery. Says Dr Nick Palmer, Clinical Research Fellow... view more... (1999-01-22)
How blood flow dictates gene expression
Researchers at the University of Pennsylvania School of Medicine have pinpointed a key regulatory protein that translates blood flow into gene expression. view more (2006-12-21)
Bio-engineering of blood vessels
Blood vessel prostheses work best when the biochemical and mechanical properties match reality as much as possible and when they are made of biodegradable material. To this end tissue technologists grow natural vascular wall cells, endothelial cells, in a biodegradable tube made of collagen. According to Professor Istv'¡n Vermes tissue... view more...

In preeclampsia, researchers identify proteins that cause blood vessel damage
Proteins released by the placenta may damage blood vessels in women with preeclampsia (PE), according to an abstract presented by Yale School of Medicine researchers at the Society for Gynecologic Investigation Conference March 17 in Reno, Nevada. view more (2007-03-19)
New technique appears to stop abnormal blood vessel growth
A manmade protein with a tail of amino acids delivered to target cells can dramatically reduce blood vessel growth that obstructs vision or feeds a tumor, researchers have found. view more (2005-06-01)
Novel findings about neovessel formation
The main role in new findings about neovessel formation is played by a protein called tissue factor. This factor turns out to have both a stimulatory function and an inhibitory function in the generation of blood vessels. Normally these two functions neutralize each other, but in diseases like retinopathy - where unwanted blood vessels grow into... view more... (2004-05-10)
Sight gone, but not necessarily lost?
Like all tissues in the body, the eye needs a healthy blood supply to function properly. Poorly developed blood vessels can lead to visual impairment or even blindness. view more (2009-11-02)
Basis created for directing and filming blood vessels
A new method of filming blood-vessel cells that move in accordance with targeted signals has been developed by researchers at Uppsala University in collaboration with researchers at the University of California. The method can also be used to study how migration of cancer cells and nerves can be controlled. view more (2008-03-27)
Blood vessels contribute to their own growth and oxygen delivery to tissues and tumors
Researchers at the University of North Carolina at Chapel Hill School of Medicine and the College of Arts & Sciences have identified a new biological process that spurs the growth of new blood vessels. view more (2009-09-15)
Impaired clearance of amyloid-beta causes vascular damage in Alzheimer's disease
New research suggests that accumulation of amyloid-β peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease. view more (2005-07-21)
Schepens scientists are first to discover angiogenesis switch inside blood vessel cells
Scientists at Schepens Eye Research Institute, an affiliate of Harvard Medical School, are the first to discover a switch inside blood vessel cells that controls angiogenesis (new blood vessel growth). view more (2006-05-19)
Angiogenesis : Blocking tumor growth and treating infarction - a new target
Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to continue growing. Inserm researchers at the... view more... (2005-04-25)
Chemistry & Industry - 15 July Issue
NEWS Nicotine may be answer to growing organs (page 4) Nicotine may prove to be the only thing that can facilitate the growth of an organ intact in the body, according to research by scientists in the US. They have shown that, in very low doses, nicotine can stimulate blood-vessel growth in damaged, blood-starved tissue, as well as recruit and... view more... (2002-07-11)
Brain tumor researchers find their 'niche'
Brain tumors appear to arise from cancer stem cells (CSCs) that live within microscopic protective "niches" formed by blood vessels in the brain; and disrupting these niches is a promising strategy for eliminating the tumors and preventing them from re-growing. view more (2007-01-17)
Alzheimer's disease; new approach, new possibilities?
Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) associated with the University of Antwerp have achieved a new breakthrough in their research on the origins of Alzheimer's disease. view more (2005-07-28)
Drugs to inhibit blood vessel growth show promise in rat model of deadly brain tumor
In a landmark study, Medical College of Wisconsin researchers in Milwaukee report that drugs used to inhibit a specific fatty acid in rat brains with glioblastoma-like tumors not only reduced new blood vessel growth and tumor size dramatically, but also prolonged survival. The study is the featured cover story of the August, 2008 Journal of... view more... (2008-08-22)
Bioengineers create stable networks of blood vessels
Yale biomedical engineers have created an implantable system that can form and stabilize a functional network of fine blood vessels critical for supporting tissues in the body, according to a report in the Proceedings of the National Academy of Sciences. view more (2006-03-01)
A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?
Angiogenesis, the growth of new blood vessels, is a central process in diverse physiological and pathological situations such as healing of wounds and traumas, cardiovascular disorders, inflammatory conditions such as rheumatoid arthritis, and in cancer growth. view more (2008-04-23)
Researchers identify ovarian cancer biomarkers
Researchers have identified markers unique to the cells of blood vessels running through ovarian tumors. The finding, while preliminary, could one day improve screening, diagnosis and treatment for this disease. view more (2007-03-08)
