Cette méthode consiste à sonder l'oeil avec un rayonnement laser à faisceau étroit et à mesurer les déformations du front d'onde dans des sous-ouvertures du rayonnement qui ressort de l'oeil, à l'aide d'un détecteur de Shack Hartman. Au cours des mesures, des déformations sont introduites dans le front d'onde et répétées plusieurs fois avec diverses déformations dans le faisceau durant chaque mesure ultérieure, la reconstruction du front d'onde étant effectuée en fonction des données obtenues dans toutes les positions angulaires du faisceau. Le dispositif de mesure comprend un canal de sonde, un canal de mesure et un canal de positionnement. Pour contrôler le front d'onde, une unité de déformation du front d'onde est introduite, sur la base d'un déflecteur optoacoustique, dans le canal de mesure, dans le premier mode de réalisation, et dans le canal de sonde, dans le second mode de réalisation. La méthode et le dispositif de la présente invention permettent de mesurer les aberrations de l'oeil dans le front d'onde avec une plus grande plage dynamique.

The reflective surface of the first disc or mirror has an axis of rotational symmetry, tilted at a first small angle relative to said first axis and the reflective surface of the second disc or mirror has an axis of rotational symmetry tilted at a second angle relative to said second axis. The driving means for the discs or mirrorsis arranged to drive these in such a way as to effect a substantially linear scan, the size of said second angle relative to said first angle being selected so as to reduce or eliminate pupil wander in the direction orthogonal to the direction of line scan.

Title: Materials and methods for inhibition of respiratory syncytial virus infection
Inventor: BEHERA ARUNA K
IPC: C12N9/12
Filed: 2003-04-30
Abstract: The subject invention concerns a method of inhibiting an RNA virus infection within a patient by increasing the amount of 2-5 oligoadenylate (2-5 AS) activity within the patient. Preferably, the preventive and therapeutic methods of the present invention involve administering a nucleotide encoding 2- 5 AS, or at least one catalytically active fragment thereof, such as the p40 , p69, p100 subunits to a patient in need thereof. The present inventors have determined that overexpression of 2-5AS causes a reduction in epithelial cel l damage, reduction in infiltration of mononuclear cells in the peribronchiola r and perivascular regions, and reduction in thickening of the septa in the lungs. Levels of chemokines, such as MIP1-.alpha., are also reduced upon overexpression of 2-5AS. The subject invention also pertains to pharmaceutic al compositions containing a nucleotide sequence encoding 2-5AS and pharmaceutically acceptable carrier, as well as vectors for delivery of the 2- 5AS nucleotide sequence.
