Gene provides hope for restoring injured nerves

University of Utah scientists identified a worm gene that is essential for damaged nerve cells to regenerate, and showed they could speed nerve regeneration by over-activating the gene - a step toward new treatments for nerves injured by trauma or disease

Photoacoustic tomography changes lymph node biopsy, reduces radiaiton exposure

Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients.

Discovery of novel ways to halt the spread of antibiotic resistance

Scientists have identified the structure of a key component of the bacteria behind such diseases as whooping cough, peptic stomach ulcers and Legionnaires' disease.

Collagen VI protects brain cells against amyloid-beta proteins

Scientists from the Gladstone Institute of Neurological Disease (GIND), UCSF, and Stanford have discovered that a certain type of collagen, collagen VI, protects brain cells against amyloid-beta proteins, which are widely thought to cause Alzheimer's disease (AD).

Discovery of 'on switch' for cell death signaling mechanism

Scientists at Burnham Institute for Medical Research (Burnham) have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex (DISC), which is responsible for triggering apoptosis (programmed cell death).

Barcode chip enables cheaper, faster blood testing

A new barcode chip developed by a multi-institutional team of investigators promises to revolutionize diagnostic medical testing. In less than 10 minutes and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases such as cancer and heart disease.

Stem cells and leukemia battle for marrow microenvironment

Learning how leukemia takes over privileged "niches" within the bone marrow is helping researchers develop treatment strategies that could protect healthy blood-forming stem cells and improve the outcomes of bone marrow transplantation for leukemia and other types of cancer.

Researchers look at processes asbestos fibers use to trigger cancer in human cells

Ohio State University scientists believe they are the first in the world to study the molecular underpinnings of cancer by probing individual bonds between an asbestos fiber and human cells.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.

Receptor for prostaglandin-E2 plays key role in atherosclerosis development

Atherosclerosis - a disease that includes the buildup of fatty, cholesterol-laden lumps of cells inside the artery wall - is the underlying cause of heart attacks and strokes.

Breast cancer genome shows instability of cancer

A newly published genome sequence of a breast cancer cell line reveals a heavily rearranged genetic blueprint involving breaks and fusions of genes and a broken DNA repair machinery, said researchers at Baylor College of Medicine in a report that appears online in the journal Genome Research.

Atypical hyperplasia increases risk of developing breast cancer

A type of benign breast disease (BBD) known as atypical hyperplasia substantially increases a young woman's risk of developing breast cancer, even if there is no history of breast cancer in her family, say researchers at Mayo Clinic.
