Mutation in TDP-43 gene may play role in common dementia

Scientists at Washington University School of Medicine in St. Louis have linked a mutation in a gene known as TDP-43 to an inherited form of amyotrophic lateral sclerosis (ALS), the neurodegenerative condition often called Lou Gehrig's disease.

Drinking milk may help women lower risk for hypertension

Women who drank more fat free milk and had higher intakes of calcium and vitamin D from foods, and not supplements, tended to have a lower risk for developing hypertension or high blood pressure, according to a new study published in the American Heart Association journal, Hypertension.

New technique to identify, treat bacterial infections

A new technique developed by a University of Central Florida chemist will help physicians more quickly identify the bacterial infections patients have so they can be treated in hours instead of days.

Heat shock protein 90 helps explain the speed of evolution

Heat shock protein 90 (HSP90) has a greater impact on the appearance of new traits than previously expected, according to two articles published in the Proceedings of the National Academy of Science (PNAS) by researchers in Whitehead Member Susan Lindquist's lab and their colleagues in Christine Queitsch's lab at Harvard University's FAS Center for Systems Biology.

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

Risk factors for Parkinson's disease focus of new research

A new study demonstrates that high levels of MAO-B, an enzyme that regulates nerve activity in the brain, cause Parkinson's-like symptoms in mice genetically engineered to overexpress the protein.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers in a multi-institutional study led by Cincinnati Children's Hospital Medical Center slowed the growth of two particularly stubborn solid tumor cancers - neuroblastoma and peripheral nerve sheath tumors - without harming healthy tissues by inserting instructions to inhibit tissue growth into an engineered virus, according to study results published in the February 15 Cancer Research.
