Abstract: The invention provides a method and a system of checking a procedure for the optical inspection of glass containers (12), characterized by a procedure for the optical recognition of a control mark (42) of a control container having optical properties of transformation spectral such that: the transformation of the spectral intensity distribution between the incident (LRi) and return (LRr) recognition lights, by the mark (42), is different from that caused by interaction with a marking portion free of any mark (46); the transformation of the spectral intensity distribution between the incident (LIi) and return (LIr) inspection lights, by the mark, is not different, inside at least one useful portion of the inspection spectral band (BSI), from that caused by interaction with a marking portion free of any mark (46).

Abstract: The present invention relates to nuclease protein fusions for enhancing genome editing by homology-directed transgene integration (HDI). The inventors found that the rate of HDI mediated by the CRISPR/Cas9 system may be substantially improved by providing the Cas9 nuclease in the form of a fusion protein with at least the N-terminal domain of the CtIP protein. CtIP proteins are involved in the early steps of homologous recombination. In addition, the inventors identified the subdomains of the N-terminal domain of the CtIP protein that are important for improving the HDI rate. Thus, the invention relates to fusion proteins comprising a Cas9 protein, a tetramerization domain of a CtIP protein and a dimerization domain of a CtIP protein. Particularly, the inventors have tested these fusion proteins HEK293 cells, RG37DR cells and Sprague-Dawley rats.

Abstract: A method of inspecting articles of transparent/translucent material with a vision system comprises illuminating the articles with a light source having an angular spectrum that is adapted to the contrast selected for refractive items presented by the articles. An image sensor picks up the light that has passed through the articles to make images of the articles. During a stage of referencing the vision system, a reference standard is in the field of view of the image sensor, the standard including at least one standard item that refracts light in a known range of angles. An image of the standard is taken to measure at least the contrast in the image produced by at least one standard item. During at least one stage of qualifying the vision system, the standard is placed once more in front of the light source and in the field of view of the image sensor.

Abstract: The invention relates to a method of generating junctional variability in the nucleotide sequence of a polynucleotide of interest present in an intrachromosomal substrate/context in a eukaryotic cell which is competent for canonical Non Homologous End Joining pathway (NHEJ) repair, involving the generation of double-strand break (DSB) in the DNA sequence of said polynucleotide, and involving the use of polymerase Terminal Deoxynucleotidyl Transferase (TdT) in conditions enabling said TdT to add Non-templated nucleotides (N nucleotides) before ligation through the canonical Non Homologous End Joining pathway (NHEJ) thereby allowing a mutagenic repair to take place at the DSB site.
