Tissue scarring key to link between obesity and diabetes

The team, in collaboration with University Hospital Aintree, the University of Warwick and researchers in Sweden, found that people classified as obese and those with pre-diabetes have raised levels of a protein called SPARC, that can cause tissue scarring.

When cell death goes wrong - scientists gain new insights

Medical Research Council (MRC) scientists have made an important advance in understanding the biological processes involved when cells are prompted to die. The work may help scientists to eventually develop new treatments for the many common diseases and conditions which occur when cell death goes wrong.

Human brain distinctly separates living and non-living objects for processing

For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. For years, many scientists have assumed the brain segregated visual information in this manner to optimize processing the images themselves, but new research shows that even in people who have been blind since birth the brain still separates the concepts of living and non-living objects.

Why GPs won’t take part in research

A group of researchers whose planned leg ulceration study was hamstrung by a physician recruitment rate of 2% have published the reasons why so many doctors turned them down. The qualitative information, featured in the open access journal BMC Medical Research Methodology, should be of use to those designing trials of their own.

Discovery of compounds that selectively kills cancer stem cells

The cancer stem cells that drive tumor growth and resist chemotherapies and radiation treatments that kill other cancer cells aren't invincible after all. Researchers reporting online on August 13th in the journal Cell, a Cell Press publication, have discovered the first compound that targets those cancer stem cells directly.

A healthy diet helps prevent kidney stones

Researchers have found another reason to eat well: a healthy diet helps prevent kidney stones. Loading up on fruits, vegetables, nuts, low-fat dairy products, and whole grains, while limiting salt, red and processed meats, and sweetened beverages is an effective way to ward off kidney stones, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN).

Protein plays unexpected role protecting chromosome tips

A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell.

Scientists grow new blood vessels to combat heart disease

Although open-heart surgery is a frequent treatment for heart disease, it remains extremely dangerous. Now groundbreaking research from Dr. Britta Hardy of Tel Aviv University's Sackler School of Medicine has shown the potential for an injected protein to regrow blood vessels in the human heart ― eliminating the need for risky surgery altogether.
