Non-invasive radio waves heat up nanotubes to destroy cancer

Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center and Rice University has shown in preclinical experiments.

Researchers find stem cells in degenerating spinal discs, potential for repair

Orthopedic researchers at Jefferson Medical College have for the first time found stem cells in the intervertebral discs of the human spine, suggesting that such cells might someday be used to help repair degenerating discs and remedy lower back and neck pain.

How can some people live at high altitudes and thrive while others struggle?

The answer for Tibetans who live at altitudes around 14,000 feet is increased nitric oxide (NO) levels. High levels of NO circulate in various forms in the blood and produce the physiological mechanisms that cause the increased blood flow that maintains oxygen delivery despite hypoxia - low levels of oxygen in the ambient air and the bloodstream.

Preventing lung scarring may extend lives of lung cancer patients

Researchers have found that using a special type of drug called a pharmaceutical monoclonal antibody to block the integrin beta6-TGF-beta pathway prevents a serious side effect of radiation therapy for lung cancer patients – pulmonary fibrosis (scarring of the lungs), thereby extending patients' lives and improving their quality of life, according to a study presented at the Plenary I session on October 29, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.

Blood markers can help choose best dose for antiangiogenic drugs

Scientists at Sunnybrook have new information that may help to improve the use of anti-cancer drugs designed to block the growth of new blood vessels in tumors, a process called angiogenesis that is critical to tumor growth.

Recent colds influence adverse respiratory events after surgery in children

For children undergoing general anesthesia for surgery or other procedures, the risks of several adverse respiratory (breathing-related) events are greater if the child has recently had a cold or other upper respiratory infection (URI).

Uvulopalatopharyngoplasty may help those with obstructive sleep apnea

A procedure known as uvulopalatopharyngoplasty (UPPP) may help some patients improve or even eliminate their obstructive sleep apnea (OSA), according to a new study.

Combination targets offer new hope in fight against cancer

While some targeted therapies - drugs developed to attack specific molecules in the critical chemical pathways occurring within cancer cells - work well by themselves, increasingly researchers are finding that they work better when teamed with other targeted and conventional therapies.

Endobronchial valve improves quality of life in emphysema patients

Emphysema patients whose lungs are implanted with a pencil eraser-sized, one-way endobronchial valve experience significantly improved measures of lung function and report better quality of life, University of Pittsburgh School of Medicine researcher Frank C. Sciurba, M.D., reported today at CHEST 2007, the annual meeting of the American College of Chest Physicians.

New pathway identified by which cancer cells grow and survive

Cancerous tumors are wildly unfavorable environments. Struggling for oxygen and nutrients while being bombarded by the body's defense systems, tumor cells in fact require sophisticated adaptations to survive and grow.

Pine bark extract boosts nitric oxide production

A study to be published in the October edition of Hypertension Research reveals Pycnogenol, (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, helps individuals by enhancing healthy nitric oxide (NO) production which leads to an increase in blood flow and oxygen supply to muscles.
