ORBi Open Repository and Bibliography (324.361 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  4. VitriCell: the safest key for cryopreserving your valuable cells

    Connan, Delphine; Ectors, Fabien; Vanderzwalmen, Pierre; Antoine, Nadine; Grobet, Luc
    VITRICELL is a future spin-off company aiming at providing standard and customized solutions for safe and efficient cryopreservation of valuable and sensible eukaryotic cells. Developed in the Embryology unit of the Faculty of Veterinary Medicine of the University of Liège, the core methodology relies on aggregation of inventor’s pioneering expertises in the fields of stem cells engineering, vitrification of gametes and embryos and in assisted reproductive technologies. VITRICELL will soon provide researchers and clinicians with vitrification kits, allowing upgrade of the current yields and safety after cryopreservation of their high-value cells. The benefits of our method are the most prominent...

  5. Efficient aseptic and automatable vitrification of human Embryonic Stem Cells using bio-safe & chemically defined media

    Connan, Delphine; Ectors, Fabien; Piret, Joëlle; Antoine, Nadine; Grobet, Luc
    We have demonstrated on human pluripotent stem cells that, despite additional constraints (aseptic, defined medium, automatable…), our aseptic (i.e. in closed systems) and chemically defined (i.e. without complex undefined compinent) vitrification method is more efficient than conventional slow freezing. We can also conclude that the cells keep their biological (pluripotency) properties after aseptic vitrification, including a normal karyotype and the capacity to generate teratoma when injected in immunodeficient mice. Aseptic vitrification of human Pluripotent Stem Cells is now possible in completely defined media. Because straws are directly immersed in LN2, this method does not require any specific and expensive material....

  6. Aseptic and automatable vitrification of human embryonic stem cells using defined media

    Ectors; Connan, Delphine; Grobet, Luc
    This talk reports on progress and achievements of University of Liège (coordinator) and Glycomar company for developping a novel technology for cryopreserving human embryonic stem cells intended for therapeutic use in cell-bases regenerative thérapies.

  9. Thaxtomin A: a promising alternative to synthetic herbicides

    Deflandre, Benoit; Jourdan, Samuel; Francis, Isolde M.; Loria, Rosemary; Rigali, Sébastien
    In times of trouble for the world’s most popular herbicide – namely Bayer / Monsanto’s Roundup – finding alternatives to glyphosate has become a priority for some companies willing to capture this highly valuable market. Besides synthetic herbicides and their derivatives that are being developed in the industry, interest is growing for natural and ‘green’ active molecules. The plant pathogen Streptomyces scabies provides an interesting clue, as its main virulence factor is a phytotoxin called thaxtomin A. This filamentous Gram + bacteria is known as the causing agent of the common scab disease affecting tuber crops. While it was discovered...

  20. Advances in Triticum aestivum- Rhizoctonia cerealis interacntions

    Rong, Wei
    Plant-pathogen interactions have been performed extensively over the years from both plant and pathogen viewpoint. An overall understanding of how plant and pathogen recognize each other, and the differentiate to establish either a compatible or an incompatible relationship is crucial in this field of inverstigation. With transcriptomics approaches, we could successfully identify the defence-related genes expressed during phytopathogen infections. The plant-paghogen interactions and findings considering the wheat sharp eyespot, Rhizoctonia cerealis and transcriptomics were summeriszed in this paper. We also discussed these findings considering the advantages and limitations of current transcriptomic tool in plant-pathogen interactions.
