Abstract: The subject invention provides a method of preventing a neurodegenerative disease in a subject or oxidative stress in the brain of a subject, comprising administering to the subject a less than cholinesterase-inhibitory amount or a less than monoamine oxidase-inhibitory amount of R(+)-6-(N-methyl,N-ethyl-carbamoyloxy)-N?-propargyl-1-aminoindan or a salt thereof effective to prevent the neurodegenerative disease or oxidative stress in the subject.

Abstract: The present invention provides a unique profile of volatile organic compounds as breath biomarkers for lung cancer. The present invention further provides the diagnosis, prognosis and monitoring of lung cancer or predicting the response to an anti-cancer treatment through the detection of the unique profile of volatile organic compounds indicative of lung cancer at its various stages.

Abstract: A system and method are provided for imaging in scattering media such as fog, water and biological tissues. Normally, such images suffer from poor visibility due to backscattering and signal attenuation. At least two images are taken of the scene using active widefield polarized illumination, with different states of a camera-mounted polarizer. The degree of polarization of backscatter is estimated in every point of the scene, leading to an estimation of the backscatter in every point of the scene. A portion or all of the value of backscatter can be deducted in each point of the scene resulting in an enhanced image with improved contrast and brightness range across the field of view.
