New method helps engineer tissues with embedded nanoscale networks

A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks—which mark the first time that electronics and tissue have been truly merged in 3D—allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.

Thiabendazole drug slows tumor growth and shows promise as chemotherapy for cancer

An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans.

Special device provides evidence of how bloodstream infections begin

New research may help explain why hundreds of thousands of Americans a year get sick - and tens of thousands die - after bacteria get into their blood. It also suggests why some of those bloodstream infections resist treatment with even the most powerful antibiotics.

Implanted cells' therapeutic properties depend on their shape

Tissue implants made of cells grown on a sponge-like scaffold have been shown in clinical trials to help heal arteries scarred by atherosclerosis and other vascular diseases. However, it has been unclear why some implants work better than others.

Leukoaraiosis modifies brain function in the elderly

Researchers at the Mayo Clinic say a common condition called leukoaraiosis, made up of tiny areas in the brain that have been deprived of oxygen and appear as bright white dots on MRI scans, is not a harmless part of the aging process, but rather a disease that alters brain function in the elderly.

About half of adults with type 2 diabetes experience acute and chronic pain

Almost half of adults with type 2 diabetes report acute and chronic pain, and close to one quarter report neuropathy, fatigue, depression, sleep disturbance and physical or emotional disability, according to a study of more than 13,000 adults conducted by researchers at the San Francisco VA Medical Center, the University of California, San Francisco and the Kaiser Permanente Division of Research in Oakland, CA. The researchers also found significant rates of shortness of breath, nausea and constipation.

Scientists identify biological mechanism that may be responsible for icy extremities

Cold feet-those chilly appendages that plague many people in the winter and an unlucky few all year round-can be the bane of existence for singles and couples alike. In a new study, scientists led by Selvi C. Jeyaraj of the Research Institute at Nationwide Children's Hospital have identified a biological mechanism that may be responsible for icy extremities: an interaction between a series of molecules and receptors on smooth muscle cells that line the skin's tiny blood vessels.

Specific autoantibodies associated with blood vessel damage in the brain

The presence of specific autoantibodies of the immune system is associated with blood vessel damage in the brain. These findings were made by Marion Bimmler, a graduate engineer of medical laboratory diagnostics at the Max Delbr-ck Center for Molecular Medicine Berlin-Buch and Dr. Peter Karczewski of the biotech company E.R.D.E.-AAK-Diagnostik GmbH in studies on a rat model.
