  • Patent number: 12011466
    Abstract: The invention relates to the field of modified Escherichia coli strain Nissle 1917 (EcN) and its use for treating gastro-intestinal disorders. The invention is based on the study of the mechanisms implicated in the probiotic properties of the Escherichia coli strain Nissle 1917 (EcN). This study has allowed the inventors to decouple the probiotic activity of EcN from its genotoxic activity by demonstrating that EcN ClbP protein, the enzyme that activates the genotoxin colibactin, is also required for the siderophore-microcins activity of probiotic EcN, but interestingly, not its enzymatic domain that cleaves precolibactin to form active colibactin.

  • Patent number: 11912645
    Abstract: The invention is based on the discovery of a new bacterial compound with analgesic properties which could be used as a new tool for the treatment of pain disorders such as visceral pain. Studying the mechanisms implicated in analgesic properties of the probiotic Escherichia coli strain Nissle 1917 (EcN), inventors characterized, the amino fatty acids produced by EcN, which display the Ecn analgesic properties. One of these compounds inhibits the hypersensitivity to colorectal distension induced by capsaicin, which is a very powerful nociceptive compound and acts via the GABA B receptor. Furthermore, inventors demonstrate that this compound is able to cross the cellular epithelial barrier (such as the intestinal epithelium). Thus, the invention relates to a lipopetide compound, derived from gamma-aminobutyric acid. The invention also relates to a lipopeptide compound according to the invention for the treatment of treating pain disorder, such as somatic pain and visceral pain.

  • Patent number: 7696095
    Abstract: The present invention provides auto-stopping CMP slurry compositions that minimize post-CMP non-uniformity and also extend the time that polishing can be continued beyond the end point without the risk of over-polishing the dielectric silicon dioxide film. Auto-stopping CMP slurry compositions according to the invention include ceria abrasive particles and an effective amount of a polyalkylamine such as polyethyleneimine dispersed in water. The methods of the invention include polishing a topographic dielectric silicon dioxide film layer using the auto-stopping CMP slurry compositions to obtain a dielectric silicon dioxide surface having a desired predetermined minimum step height.

  • Publication number: 20060216935
    Abstract: The present invention provides an oxide CMP slurry composition for use in planarizing silicon oxide-containing films via CMP during CMOS device fabrication, and a method of planarizing silicon oxide-containing films via CMP using the slurry composition. The oxide CMP slurry composition according to the invention includes: (i) proline, lysine and/or arginine; (ii) a pyrrolidone compound; and (iii) abrasive particles. Proline is presently most preferred for use in the invention. In the STI sub-process of the CMOS device fabrication process, the oxide CMP slurry composition according to the present invention acts to aggressively remove only the silicon dioxide overburden on the processed wafer that is in contact with a polishing pad, which results in the formation of a substantially planar, defect-free surface.
