FDA Approves TYVASO (Treprostinil) Inhalation Solution For The Treatment Of Pulmonary Arterial Hypertension
United Therapeutics Corporation (Nasdaq: UTHR) announced that the United States Food and Drug Administration (FDA) has approved TYVASO (treprostinil) Inhalation Solution for the treatment of pulmonary arterial hypertension (PAH) using the TYVASO Inhalation System (which includes the Optineb-ir device and accessories). TYVASO is indicated to increase walk distance in patients with NYHA Class III symptoms associated with WHO Group I PAH, which includes multiple etiologies such as idiopathic and familial PAH as well as PAH associated with scleroderma and congenital heart disease.

Researchers Profile Gene Activity In Acutely Ill Idiopathic Pulmonary Fibrosis Patients
New research may help doctors pinpoint when patients with idiopathic pulmonary fibrosis (IPF) are becoming dangerously ill. The findings may also point the way to interventions that could sustain the lives of IPF patients until life-saving transplants could be performed.

Academy Publishes New Volume Of Essays Examining The Use Of fMRI To Recognize Deceit

The American Academy of Arts and Sciences has published a new collection of essays, "Using Imaging to Identify Deceit: Scientific and Ethical Questions," examining the scientific support for using functional magnetic resonance imaging (fMRI) to recognize deception. The seven essays, authored by scholars of neuroscience, law, and philosophy, also consider the legal and ethical concerns raised when machine-based means are employed to identify deceit. "The pace of scientific discovery and the subsequent applications of new technology create questions that extend beyond the boundaries of science," says neuroscientist Emilio Bizzi, President of the American Academy and Institute Professor at the Massachusetts Institute of Technology. "This adaptation of medical technology generates unique legal and ethical concerns that benefit from the thoughtful opinions of this diverse collection of scholars." The authors of express a dim view of lie detection based on fMRI technology. They also consider the widely used polygraph and conclude that both it and fMRI are unreliable. Using Imaging to Identify Deceit: Scientific and Ethical Questions includes the following essays: * "Imaging Deception" Emilio Bizzi, Institute Professor, Massachusetts Institute of Technology; Steven E. Hyman, Provost, Harvard University and Professor of Neurobiology, Harvard Medical School * "An Introduction to Functional Brain Imaging in the Cortex of Lie Detection" Marcus E. Raichle, Professor of Radiology, Neurology, Neurobiology and Biomedical Engineering, Washington University in St. Louis * "The Use of fMRI in Lie Detection: What Has Been Show and What Has Not" Nancy Kanwisher, Ellen Swallow Richards Professor of Cognitive Neuroscience, Massachusetts Institute of Technology * "Lying Outside the Laboratory: The Impact of Imagery and Emotion on the Neural Circuitry of Lie Detection" Elizabeth A. Phelps, Silver Professor of Psychology and Neural Science, New York University * "Actions Speak Louder than Images" Stephen J. Morse, Ferdinand Wakeman Hubbell Professor of Law and Professor of Psychology and Law in Psychiatry, University of Pennsylvania * "Neural Lie Detection in Courts" Walter Sinnott-Armstrong, Professor of Philosophy and Hardy Professor of Legal Studies, Dartmouth College * "Lie Detection in the Courts: The Vain Search for the Magic Bullet" Jed S. Rakoff, United States District Judge for the Southern District of New York * "Neuroscience-Based Lie Detection: The Need for Regulation" Henry T.
