 Scientists thought they had a good model to explain how the inner ear translates vibrations in the air into sounds heard by the brain. Now, based on new research from the Stanford University School of Medicine, it looks like parts of the model are wrong. |

A team of scientists from the Center for Applied Medical Research (CIMA) of the University of Navarra has identified a key enzyme in the development of cardiac insufficiency. This enzyme is involved in the accumulation of fibrous tissues in the hearts of patients with chronic cardiac diseases and deterioration of heart functions. |

 Dr. Nicolas Bazan, Director of the Neuroscience Center of Excellence, Boyd Professor, and Ernest C. and Yvette C. Villere Chair of Retinal Degenerative Diseases Research at LSU Health Sciences Center New Orleans, will present new research findings showing that an omega three fatty acid in the diet protects brain cells by preventing the misfolding of a protein resulting from a gene mutation in neurodegenerative diseases like Parkinson's and Huntington's. |

 The most disabling aspect of Tourette syndrome is that in 90% of cases, it exists in conjunction with another disorder. The most frequent co-occurring condition in people with Tourette is attention deficit hyperactivity disorder (ADHD), though the cause of this association is uncertain. Having one disorder can be disabling enough, but having two means coping with more than twice the disability. |

 When plaques coating blood vessel walls rupture and expose collagen, platelets spring into action to form a blood clot at the damaged site. Now, a new report in the April 17th issue of the journal Cell reveals how those life-threatening clots—a leading cause of death in the United States, Europe and other industrialized countries--get an early grip. The discovery might offer a new way to fight clot formation before it can even begin, according to the researchers. |

 With eight basic medical facts in hand, doctors can now estimate the risk of bleeding for a patient having a heart attack. Using clinical variables, researchers at Washington University School of Medicine in St. Louis, Duke University and collaborating institutions have created a new method to estimate bleeding risk and help lessen the chances that heart attack patients will experience this common complication.

Fetal alcohol spectrum disorder (FASD) and Fetal alcohol syndrome (FAS) cause malformations in babies, including facial defects, short stature, and mental and behavioral abnormalities. The African frog, Xenopus, is a valuable tool for understanding early vertebrate development since these embryos are large, easy to work with and very responsive to environmental cues. New research uses this system to address the mechanism underlying the characteristics associated with maternal consumption of alcohol in early pregnancy. |
