Text messages helpful in controlling diabetes

Posted: 13 Jun 2014 07:51 PM PDT

A text message-based self-management intervention improves glycemic control in high risk Latinos with type 2 diabetes, a study shows. The messages in the study focused on healthy nutrition tips, the benefits of physical activity and medication adherence, and requests to check blood sugar and send back results. Two to three messages were sent each day at the beginning of study enrollment, and the frequency tapered off over a six-month period.

Antibodies from desert as guides to diseased cells

Posted: 12 Jun 2014 06:52 AM PDT

Nanoparticles are considered a promising approach in detecting and fighting tumor cells. The method has, however, often failed because the human immune system recognizes and rejects them before they can fulfill their function. Researchers have developed nanoparticles that bypass the body's defense system and find the diseased cells. This procedure uses fragments from an antibody that only occurs in camels and llamas.

Drivers of rheumatoid arthritis identified

Cutting-edge tetramer technology has been used to find the T cells that drive rheumatoid arthritis. This tool now allows scientists to study how RA starts, how current therapies may impact the immune response directed to the joint and how to specifically target these cells therapeutically. An estimated 1.3 million people in the United States have RA -- almost 1 percent of the nation's adult population. There are nearly three times as many women as men with the disease.

New tumor-targeting agent images, treats wide variety of cancers

Posted: 11 Jun 2014 11:36 AM PDT

A new class of tumor-targeting agents can seek out and find dozens of solid tumors, even illuminating brain cancer stem cells that resist current treatments, researchers report. What's more, years of animal studies and early human clinical trials show that this tumor-targeting, alkylphosphocholine (APC) molecule can deliver two types of "payloads" directly to cancer cells: a radioactive or fluorescent imaging label, or a radioactive medicine that binds and kills cancer cells.

New composite protects from corrosion at high mechanical stress

Posted: 11 Jun 2014 06:32 AM PDT

A composite material that prevents metal corrosion in an environmentally friendly way, even under extreme conditions, is being announced by researchers. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.

Improvements in MRI, passenger screening, other image-detection applications on the horizon

Posted: 11 Jun 2014 06:31 AM PDT

Researchers are developing new terahertz detectors based on carbon nanotubes that could lead to significant improvements in medical imaging, airport passenger screening, food inspection and other applications.
