Scientist uses GPUs to simulate inner workings of human cells

The cure for cancer comes down to this: video games. In a research lab at Wake Forest University, biophysicist and computer scientist Samuel Cho uses graphics processing units (GPUs), the technology that makes videogame images so realistic, to simulate the inner workings of human cells.

Exposure to common flame retardant may affect fertility and long-term memory

Mice genetically engineered to be susceptible to autism-like behaviors that were exposed to a common flame retardant were less fertile and their offspring were smaller, less sociable and demonstrated marked deficits in learning and long-term memory when compared with the offspring of normal unexposed mice, a study by researchers at UC Davis has found.

Biochemists determine first crystal structure of an immunoproteasome

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells that due to a viral infection present non-self peptides at their surface. In autoimmune diseases this mechanism is deregulated and the immune system also eliminates uninfected cells by mistake.

MV-GFP extends survival of animals with medulloblastoma

A strain of measles virus engineered to kill cancer cells prolongs survival in a model of medulloblastoma that is disseminated in the fluid around the brain, according to a new study by researchers at Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute and the Mayo Clinic.

Thrombocytosis linked to severity of ovarian cancer

Highly elevated platelet levels fuel tumor growth and reduce the survival of ovarian cancer patients, an international team of researchers led by scientists at The University of Texas MD Anderson Cancer center reports in the New England Journal of Medicine.

UCSF stem cell study suggests novel strategy for heart attack

A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels - and avoid the risk of tissue rejection.

Pyromaker can rapidly sequence cancer-driving mutations

Using precise information about an individual's genetic makeup is becoming increasingly routine for developing tailored treatments for breast, lung, colon and other cancers. But techniques used to identify meaningful gene mutations depend on analyzing sequences of both normal and mutant DNA in tumor samples, a process that can yield ambiguous results. Now, a team of Johns Hopkins researchers says it has developed an easy-to-use online computer software application that can clear up any confusion faster and cheaper than other methods currently used to do the job.

RUMC conducts early phase trial of MSDC-0160 for dementia

Researchers at Rush University Medical Center are conducting an early phase clinical trial of a novel drug therapy for patients with dementia due to Alzheimer's disease. The drug is a new compound called MSDC-0160, which is an insulin sensitizer that modulates mitochondrial metabolism.

WSU's novel gene-therapy for blindness receives $250,000 FFB grant

Technology to restore vision through the use of a component of green algae - developed by a Wayne State University professor and scientific director of the Ligon Research Center of Vision at the Kresge Eye Institute - has attracted additional funding for therapy development.

Direct link between short telomere length, heart attack and early death

Every cell in the body has chromosomes with so-called telomeres, which are shortened over time and also through lifestyle choices such as smoking and obesity. Researchers have long speculated that the shortening of telomeres increases the risk of heart attack and early death. Now a large-scale population study in Denmark involving nearly 20,000 people shows that there is in fact a direct link, and has also given physicians a future way to test the actual cellular health of a person.
