Insulin :: Smart insulin nanostructures pass feasibility test, UT study reports

Biomedical engineers at the University of Texas School of Health Information Sciences at Houston have announced pre-clinical test results in the September issue of the International Journal of Nanomedicine demonstrating the feasibility of a smart particle insulin release system that detects spikes in glucose or blood sugar levels and releases insulin to counteract them

Air Pollution :: UCLA study links air pollution to clogged arteries

Got high cholesterol? You might want to stay away from air pollution. That?s the message of a new UCLA study linking diesel exhaust to atherosclerosis, or hardening of the arteries, which significantly increases one?s risk for heart attack and stroke.

Lung Cancer :: Substance in tree bark could lead to new lung cancer treatment

Researchers at UT Southwestern Medical Center have determined how a substance derived from the bark of the South American lapacho tree kills certain kinds of cancer cells, findings that also suggest a novel treatment for the most common type of lung cancer.

Health Care :: Using nanotechnology to improve health care in developing countries

What is nanotechnology? How is nanotechnology expected to transform medicine and health care in the future? How can nanomedicine help the truly needy in developing countries? And what are the challenges of ensuring that nanotechnology meets the specific health needs of Third World peoples? These questions are the focus of an event and live Web cast at noon Tuesday, Feb_27 in the 5th Floor Conference Room of the Woodrow Wilson International Center for Scholars.

Tumor :: Homing nanoparticles pack multiple assault on tumors

Researchers have developed nanoparticles that seek out tumors and bind to their blood vessels, and then attract more nanoparticles to the tumor target. Using this system they demonstrated that the homing nanoparticle could be used to deliver a “payload” of an imaging compound, and in the process act as a clotting agent, obstructing as much as 20 percent of the tumor blood vessels.

Nanotechnology :: Future of nanotechnology discussed by experts

Many people believe nanotechnology will be the key to solving many of the world’s most pressing medical problems, while others believe it could lead to a potential disaster. The current issue of the Journal of Law, Medicine & Ethics addresses this issue in all its aspects.
