Abstract: Une structure submicronique est fabriquée dans un matériau diélectrique transparent en focalisant des impulsions laser femtoseconde dans le diélectrique pour créer une zone très effilée avec modification des propriétés de gravure. Le matériau diélectrique est ensuite gravé sélectivement dans la zone de modification depuis la direction de l'extrémité étroite de la zone effilée de sorte que la gravure sélective procède longitudinalement dans la zone modifiée, la largeur augmentant progressivement de la zone modifiée pour compenser une gravure latérale se produisant plus près de l'extrémité étroite de manière à produire des trous à parois abruptes. La partie non gravée de la zone modifiée produite par translation du faisceau laser à proximité de et parallèlement à la surface inférieure du diélectrique peut servir de guide d'onde optique pour collecter la lumière provenant de ou fournir de la lumière sur le canal gravé qui peut contenir diverses matières biologiques, optiques ou chimiques pour des applications de détection.

Title: Medium for contrast enhancement or convenience for ultrasonic, endoscopic, and other medical examinations
Inventor: DE ZIEGLER DOMINIQUE
IPC: A61B5/055
Filed: 2003-05-08
Granted: 2012-01-03
Abstract: The present invention relates to a particularly convenient medium for providing contrast enhancement and/or distension of the subject body or organ cavity during imaging, radiographic, visualization, or other similar medical examinations, including ultrasound, endoscopic examinations, MRI, x-ray, hystero-salpingograms, CT scans, and similar procedures. The present invention provides the contrast enhancement and/or distends the body or organ cavity without constant leakage of the medium or the resulting need to constantly or repeatedly infuse additional medium. The medium is designed to have sufficient viscosity or consistence initially - whether as a solid, semi-solid, gel, viscous fluid, or otherwise - to remain in the body or organ cavity for a time generally sufficient to complete the procedure, and then to facilitate easy removal or expulsion from the cavity, preferably by liquefying or losing viscosity. For imaging and radiographic examinations, the medium may provide enhanced contrast as well as the distension of the cavity. For visualization examinations, the medium typically would be optically transparent but provide the convenient reliable distension. The phase or viscosity change may be triggered by a variety factors, such as the passage of time, a change in temperature or pH, the addition of another substance, or any other trigger that liquefies or otherwise facilitates easy removal or expulsion of the composition from the cavity.

Granted: 2014-02-25
Abstract: The invention relates to an optimized method for the production of PUFAs by cultivating microorganisms belonging to the group of Stramenopiles in a fermentation medium that is pH-stabilized using calcium carbonate and comprises 3-15 g/L CaCO3, whereupon the PUFAs are isolated from the microorganisms and/or the medium. The invention particularly relates to novel optimized media having a different CaCO3 content. By using adequate quantities of CaCO3, the process can be significantly simplified during fermentation while greater quantities of DHA can be obtained at an increased oil content in the biomass. They allow microorganisms belonging to the Stramenopiles to be fermented without controlling the pH, thereby substantially improving and significantly simplifying PUFA  production.
