Immune cell age plays role in retinal damage in age-related macular degeneration
Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at Washington University School of Medicine in St. Louis have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss. view more (2007-11-02)
Model for new generation of blood vessels challenged
In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. view more (2009-06-02)
Inflammatory processes in arteriosclerosis revealed
Revolutionary new results concerning substances that play major roles in the inflammatory response have been published in the American scientific journal PNAS in two articles from Karolinska Institutet. view more (2006-07-18)
Scripps research combination therapy obliterates new vessel growth in tumors and retinopathy
While new blood vessel growth from preexisting capillaries ("angiogenesis") is fundamental to survival, the abnormal formation of new blood vessels ("neovascularization") contributes to the pathogenesis of tumor growth and metastasis as well as the vast majority of diseases that lead to catastrophic loss of vision. view more (2007-01-11)
Scientists discover why cornea is transparent and free of blood vessels, allowing vision
Scientists at the Harvard Department of Ophthalmology's Schepens Eye Research Institute and Massachusetts Eye and Ear Infirmary (MEEI) are the first to learn why the cornea, the clear window of the eye, is free of blood vessels-a unique phenomenon that makes vision possible. view more (2006-07-18)
Lung damage in babies with congenital heart disease under study
Trying to understand and stop the collateral lung damage that can occur in babies with congenital heart disease is the focus of a new study. view more (2008-03-11)
Identifying and disrupting key elements of malaria's 'sticky sack' adhesion strategy
Malaria is one of the most devastating diseases afflicting humanity. It infects and debilitates about 600 million people and kills up to three million people every year, mainly in the wet tropical regions of the world. Children and pregnant women are at particularly high risk. view more (2008-07-11)
Minimally invasive procedure restores blood flow to kidneys, research suggests
A pilot study suggests that the results of minimally invasive angioplasty and stenting to restore blood flow to the kidneys can be significantly improved if a suction device is used to remove the material blocking the vessel. view more (2006-07-05)
New Discovery Brings Hope to Treatment of Lymphatic Diseases
Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. view more (2009-08-11)
Tiny tool to control growing blood vessels opens new potential in tumor research
Researchers at Uppsala University have developed a new tool that makes it possible to study the signals in the body that control the generation of blood vessels. view more (2009-02-23)
Blood vessel protein reverses macular degeneration, diabetic retinopathy in mice
Two major eye diseases and leading causes of blindness-age-related macular degeneration and diabetic retinopathy-can be reversed or even prevented by drugs that activate a protein found in blood vessel cells, researchers at the University of Utah School of Medicine and several other institutions have announced in a new study. view more (2008-03-17)
Drawing a crowd: Understanding the signals that bring inflammatory cells into the lung
Understanding the connection between influx of immune cells into the lung and acute lung injury is essential, since lung damage tends to occur secondary to increased lung inflammation. view more (2006-02-17)
Promising target for new atherosclerosis therapies linked to leukemia
In recent years, scientists studying inflammation and atherosclerosis have seen their respective fields converging. Inflammation is an aspect of the immune response to injury and disease; atherosclerosis, with its characteristic lesions in the blood vessel walls, underlies most cardiovascular disease, including heart attacks and strokes. view more (2006-11-02)
Nano-sized technology has super-sized effect on tumors
Anyone facing chemotherapy would welcome an advance promising to dramatically reduce their dose of these often harsh drugs. Using nanotechnology, researchers at Washington University School of Medicine in St. Louis have taken a step closer to that goal. view more (2008-04-03)
Fewer adverse cardiac events at one year
Late breaking results from the SPIRIT III trial, presented at TCT 2007, the annual scientific symposium of the Cardiovascular Research Foundation, show that after 12 months, there were significantly fewer major adverse cardiac events (MACE) such as heart attacks, deaths from cardiac causes or repeat procedures (angioplasty or surgery) to clear the... view more...

New Developments in Angiogenic Therapy Emerging from Oxford
Angiogenesis, the growth of new blood vessels, is important in the healthy body for healing wounds and, in females, for the monthly reproductive cycle and during pregnancy. It is controlled in the body through the use of the body’s own angiogenesis inhibitors and stimulators. In certain diseases the body is unable to control blood vessel... view more... (2002-08-23)
Researchers study potential health benefits of natural chemicals in muscadine grape seeds
Could some of the natural chemicals found in plants be powerful enough to improve cardiovascular health" Researchers at Wake Forest University Baptist Medical Center are conducting the first-ever clinical study to evaluate the potential cardiovascular health effects of Nature's Pearl Muscadine Grape Seed Supplement. view more (2007-10-25)
New study suggests special cocoa may lead to sustained improvement in blood vessel function
Drinking a specially-made cocoa beverage daily may have the potential to reverse impairments in the functioning of blood vessels, according to a first-of-its-kind study published in the Journal of Cardiovascular Pharmacology. view more (2007-03-07)
Protein complementarity may offer new insights into autoimmune diseases
The discovery of "complementary" antibodies against plasminogen in patients with blood vessel inflammation caused by anti-neutrophil cytoplasmic autoantibodies (ANCAs) may lead to new approaches to research, testing, and treatment of ANCA vasculitis and other autoimmune diseases, suggests a paper in the December Journal of the American... view more...

Proteins in urine predict brain damage in laboratory animals
The study dealt with the development and prevention of strokes in particular rats which had spontaneously developed extremely high blood pressure. Such a high blood pressure level leads within a few weeks to damage to the kidneys, heart and brain such that the rats die. The researchers found that brain damage in these rats is always preceded by... view more... (1999-06-21)
