  • Patent number: 10695737
    Abstract: A novel miniaturized and highly automated method for the controlled printing of large arrays of nano- to femtoliter droplets is presented by actively transporting mother droplets over hydrophilic-in-hydrophobic micropatches. The proposed technology consists of single plate or double-plate devices where mother droplets can be actuated and hydrophilic-in-hydrophobic micropatches on one or both plates of the device where nano- to femtoliter droplets are printed. Due to the selective wettability of the more wettable hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over these arrays. The parent droplets can be moved by different droplet actuation principles, for example, by using the principle of electrowetting-on-dielectric droplet actuation. We propose another method that uses two plates that are placed on top of each other while being separated by a spacer.

  • Patent number: 10540536
    Abstract: Imaging mass spectrometry (IMS) has become a prime tool for studying the distribution of biomolecules in tissue. Although IMS data sets can become very large, computational methods have made it practically feasible to search these experiments for relevant findings. However, these methods lack access to an important source of information that many human interpretations rely upon: anatomical insight. In this work, this need is addressed by (1) integrating a curated anatomical data source with an empirically acquired IMS data source, establishing an algorithm-accessible link between them; and (2) demonstrating the potential of such an IMS-anatomical atlas link by applying it toward automated anatomical interpretation of ion distributions in tissue.

  • Publication number: 20190225662
    Abstract: The present invention relates to the field of disorders of the central nervous system, in particular neurological and psychiatric disorders, and the prevention and/or treatment thereof. In particular, the present invention relates to the finding that soluble amyloid precursor protein ? (sAPP?) presents a particular binding site, which allows for binding to the GABABR1a receptor, thereby causing an agonistic effect through specific binding to Sushi domain 1 of GABABR1a. As a result, the frequencies of excitatory and inhibitory postsynaptic currents are reduced. Accordingly, the invention provides compounds able to interfere with the association of sAPP? with Sushi domain 1 of GABABR1a and as such with selective impairment of GABABR1a beneficial in neurological and psychiatric disorders. The invention as well provides methods and (high content) screening assays for the production of said compounds.
