Breakthrough in understanding of blood vessel inflammation
Medical scientists at the University of Leicester have announced a breakthrough in their understanding of blood vessel inflammation - a serious condition which underlies health problems like organ failure in sepsis, the ability to recover from burns, and transplant rejection. The team in the... view more (2004-01-19)

Significant dementia risk attributable to small blood vessel damage
Autopsy data of 221 men and women found that the brains of one-third of individuals who had dementia before death showed evidence of small, cumulative blood vessel damage that can arise from hypertension or diabetes.   view more (2008-04-07)

Blood vessel cells are instructed to form tube-like structures
How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific... view more (2008-08-29)

Anti-fungal drug stops blood vessel growth
Researchers at Johns Hopkins have discovered to their surprise that a drug commonly used to treat toenail fungus can also block angiogenesis, the growth of new blood vessels commonly seen in cancers.   view more (2007-04-30)

Protein deficit impedes recovery after percutaneous angioplasty
If the body contains too little of the protein haptoglobin, the recovery of the blood vessels after percutaneous angioplasty is impeded. The Utrecht researcher Mirjam Smeets suspects that this is one of the reasons why 40 percent of patients who have undergone percutaneous angioplasty experience a... view more (2003-01-24)

Eyes may provide window to future strokes
Looking into our eyes may help doctors predict who is at risk for stroke. A new study found that people with changes in the small blood vessels in their eyes are more likely to later suffer a stroke than people without these signs.   view more (2005-10-11)

Bristol Scientists Discover New Molecule That Could Prevent Tumour Growth
Scientists at Bristol University have discovered a new molecule that could prevent tumour growth. Dr Dave Bates and Dr Steve Harper in the Microvascular Research Laboratories in the Department of Physiology, working in collaboration with clinicians at Southmead Hospital, have discovered a type of... view more (2002-07-12)

First evidence of gene therapy for abnormal blood vessel growth in newborns
The first evidence of the potential for gene therapy to treat eye disease that stems from abnormal blood vessel growth is revealed in research published in the British Journal of Ophthalmology. Gene therapy is a relatively new and much heralded therapeutic approach. But despite the advances in... view more (2001-07-18)

Protein controls blood vessel formation, offers new drug target
After an injury, the body grows new blood vessels to repair damaged tissue. But sometimes too much growth causes problems, as when new blood vessels in the eyes leak, causing diabetic retinopathy and blindness if not treated.   view more (2007-12-05)

Scientists discover how body fights to control spread of cancer
Scientists at the University of Liverpool have found how two molecules fight in the blood to control the spread of cancer cells.   view more (2007-01-09)

Intrinsic eye protein halts angiogenesis
Dr. Jayakrishna Ambati, of the University of Kentucky, and Dr. Balamurali Ambati, of the Medical College of Georgia, have jointly published a paper in the journal Nature detailing major research discoveries in corneal avascularity and angiogenesis.   view more (2006-10-19)

Novel computer model for blood flow could help doctors predict arterial disease
A unique computer model of how blood flows in human arteries has been developed by researchers in the UK. The model could help doctors understand the stresses that blood places on the walls of vessels and provide new insights into vascular disease. The work has been carried out by Dr Yun Xu... view more (2000-10-19)

A new jump start for aging blood vessels
Recent studies show promise for significantly reducing vascular aging by inactivating TNFa, which has been linked to blood vessel dysfunction and cell death. The related report by Csiszar et al., "Vasculoprotective effects of anti-TNFa treatment in aging," appears in the January issue of... view more (2006-12-28)

Drawing a crowd: How progenitor cells are recruited to tumor blood vessels from the bone marrow
Cells within the bone marrow (progenitor cells) that express a protein called CD34 have been shown to leave the marrow and travel to sites of tissue injury to mediate repair.   view more (2006-02-24)

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... 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.... view more (2002-04-16)

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... view more (2004-05-10)

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... view more (2008-03-27)

Impaired clearance of amyloid-beta causes vascular damage in Alzheimer's disease
New research suggests that accumulation of amyloid-Œ≤ 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)

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... view more (2005-04-25)

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)

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... view more (2002-07-11)
