Overweight Hispanic children shown to have vascular inflammation

Overweight Hispanic children with normal blood glucose (sugar) levels showed elevated markers for blood vessel inflammation that may predispose them to developing both type 2 diabetes and cardiovascular disease, says a new study led by researchers from the Joslin Diabetes Center.

New view of human brainstem

A team of scientists from Princeton University has devised a new experimental technique that produces some of the best functional images ever taken of the human brainstem, the most primitive area of the brain.

Are cataract rates on the decline?

Should glaucoma patients seeking alternative therapies trust what they find online? Are seatbelts still important to protect eyes in auto accidents, now that most cars have airbags? What's the connection between hearing loss and one form of glaucoma? These are among the topics explored in the March 2008 issue of Ophthalmology, the journal of the American Academy of Ophthalmology.

Hormones produced by the heart eliminate pancreatic cancer in mice

Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).

Protein that stimulates blood vessel growth worsens ovarian cancer

A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.

New understanding of structure and behavior of collagen

The structure and behavior of one of the most common proteins in our bodies has been resolved at a level of detail never before seen, thanks to new research performed at the Advanced Photon Source (APS) at the U.S. Department of Energy's (DOE) Argonne National Laboratory.

Adult stem cells may be beneficial for certain cardiovascular disorders and autoimmune diseases

A review of previously published research suggests that stem cells harvested from an adult's blood or marrow may provide treatment benefit to select patients for some autoimmune diseases and cardiovascular disorders, according to an article in the February 27 issue of JAMA: The Journal of the American Medical Association.

Effects of Kava on the liver

In recent years, serious concerns about the dangers of kava and the effects on the liver have resulted in regulatory agencies, such as the U.S. Food and Drug Administration and Australia's Therapeutic Goods Administration, banning or restricting the sale of kava and kava products.

Study identifies another strategy for normalizing tumor blood supply

Manipulating levels of nitric oxide (NO), a gas involved in many biological processes, may improve the disorganized network of blood vessels supplying tumors, potentially improving the effectiveness of radiation and chemotherapy.

Endoscopic ultrasound-guided therapy safe for severe gastrointestinal bleeding patients

A new Mayo Clinic study found that endoscopic ultrasound-guided therapy appears to be a safe and effective treatment for patients with severe gastrointestinal bleeding for whom conventional therapies have failed.

New way to grow blood vessels

Researchers at Dana-Farber Cancer Institute have found a previously unknown molecular pathway in mice that spurs the growth of new blood vessels when body parts are jeopardized by poor circulation.

Tumor-killing virus selectively targets diseased brain cells

New findings show that a specialized virus with the ability to reproduce its tumor-killing genes can selectively target tumors in the brains of mice and eliminate them.

New techniques for detecting blood clots/air bubbles in arteries

New techniques for detecting emboli (harmful blood clots/air bubbles in arteries) developed at the University of Leicester have played a major role in dramatically reducing stroke rates after carotid endarterectomy.

Tumor blood vessels can develop from precancerous stem cells

Tumors require a blood supply to grow, but how they acquire their network of blood vessels is poorly understood.

CT scan can harm kidneys, but cheap drug can help

As more and more Americans undergo CT scans and other medical imaging scans involving intense X-rays, a new study suggests that many of them should take a pre-scan drug that could protect their kidneys from damage.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers in a multi-institutional study led by Cincinnati Children's Hospital Medical Center slowed the growth of two particularly stubborn solid tumor cancers - neuroblastoma and peripheral nerve sheath tumors - without harming healthy tissues by inserting instructions to inhibit tissue growth into an engineered virus, according to study results published in the February 15 Cancer Research.

Researchers explain why Avastin can cause potentially fatal brain inflammation

New research by scientists at Schepens Eye Research Institute may help explain why the anti-cancer drug Avastin, which targets a growth factor responsible for creation of new blood vessels, causes potentially fatal brain inflammation in certain patients.
