New measure for the malignancy of melanoma

Every tumor, starting from a size of a few millimeters, depends on a supply of nutrients and oxygen.

Angiogenesis inhibitors, study points to limitations, solutions

A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"-succeeds at first, but then promotes more invasive cancer growth-sometimes with a higher incidence of metastases, according to a new study in animals.

Two compounds show great promise for cerebral palsy

Two compounds developed by Northwestern University chemists have been shown to be effective in pre-clinical trials in protecting against cerebral palsy, a condition caused by neurodegeneration that affects body movement and muscle coordination.

Discovery of new mechanism that tumours use to stimulate growth of blood vessels that feed them

The development of cancerous tumours is highly dependent on the nutrients the tumours receive through the blood.

Cultured cells from the bone marrow can heal nerves in diabetes model

Transplanting cells that replenish blood vessels can also restore nerve function in an animal model of diabetic neuropathy, Emory researchers have found.

Statins may treat cerebral cavernous malformation

In a finding that could save thousands of lives a year, University of Utah School of Medicine researchers have shown that a blood vessel disorder leading to unpredictable, sometimes fatal, hemorrhagic strokes, seizures, paralysis or other problems is treatable with the same statin drugs that millions of people take to control high cholesterol.

Aspirin counteracts new mechanisms of acetaminophen-induced liver damage

Overdoses of acetaminophen (also known as paracetamol) account for most drug overdoses in a number of countries, including the United States. Such overdoses damage the liver, causing acute liver failure, which can be fatal.

Researchers find molecular origin of blood stem cells

A research team led by Nancy Speck, PhD, Professor of Cell and Developmental Biology at the University of Pennsylvania School of Medicine, has identified the location and developmental timeline in which a majority of bone marrow stem cells form in the mouse embryo.

Lessons from Northwick Park drug-trial disaster

Scientists investigating the 2006 Northwick Park drug-trial disaster that left six healthy volunteers hospitalised say they have developed new pre-clinical tests that could have stopped the trial from ever going ahead.

Biomarkers in blood could aid diagnosis of two severe and debilitating forms of malaria

Canadian researchers have identified protein biomarkers that shed new light on the development of two severe and debilitating forms of malaria.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

Reprogrammable cell type depends on a single gene to keep its identity

Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it.

Discovery of new mechanism that regulates formation of blood vessels

Researchers in one of the external groups of the Instituto Gulbenkian de Ciencia (IGC), in Portugal, have discovered a novel mechanism which regulates the process whereby new blood vessels are formed and wounds heal, including chronic wounds, such as those found in diabetic patients and those suffering from morbid obesity.

Obesity raises levels of hormone leptin

Obese people who don't have high cholesterol or diabetes might think they're healthy - despite the extra pounds.

Daily rhythms in endothelial cells may explain why heart attacks occur most often in early morning hours

It's not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found.

Researchers unravel mysteries of brain aneurysms

Yale researchers have taken the first critical steps in unraveling the mysteries of brain aneurysms, the often fatal rupturing of blood vessels that afflicts 500,000 people worldwide each year and nearly killed Vice President-elect Joseph Biden two decades ago.

Further evidence that angiogenesis drugs can be much more effective when combined with chemotherapy

Scientists have thought that one way to foil a tumor from generating blood vessels to feed its growth - a process called angiogenesis - was by creating drugs aimed at stopping a key vessel growth-promoting protein.

Sensitive ultrasound to spot early-stage cancer

European researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumour cells. The technique should pick up tumours early and improve patients' chances of survival.

Vulnerable plaque may be easier to detect through optical coherence tomography

Research results indicate that optical coherence tomography (OCT), a newly evolving imaging method, may be the best tool available to detect vulnerable plaque in coronary arteries. The findings will be presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF).

New drug substantially extends survival in pancreatic cancer

A new form of chemotherapy that destroys new blood vessels that grow around tumors has produced excellent results in a phase II trial of patients with inoperable pancreatic cancer, researchers report at the 33rd Congress of the European Society for Medical Oncology (ESMO) in Stockholm.New drug substantially extends survival in pancreatic cancer
