  • Patent number: 11881016
    Abstract: A system and a method for processing an image so as to perform instance segmentation. The system/method includes: a—inputting (S1) the image (IMG) to a first neural network configured to output an affinity graph (AF), and b—inputting (S2), to a second neural network, the affinity graph and a predefined seed-map (SM), so as to determine whether other pixels belong to a same instance, and set at a first value the value of the other pixels determined as belonging to the same instance.

  • Patent number: 11814688
    Abstract: The present application relates to the field of cancer, particular to hypoxic tumors. It was found that hypoxia is an important driver for hypermethylation of (promoters of) tumor suppressor genes. As this hypermethylation is a stable signature that is also present in circulating tumor DNA in peripheral blood, detecting this methylation pattern is a surrogate marker for tumor hypoxia. This can be used to adapt therapy as well.

  • Publication number: 20220203325
    Abstract: A miniaturized, automated method for controlled printing of large arrays of nano- to femtoliter droplets by actively transporting mother droplets over hydrophilic-in-hydrophobic (“HIH”) micropatches. The technology uses single or double-plate devices where mother droplets can be actuated and HIH micropatches on one or both plates of the device where the droplets are printed. Due to the selective wettability of the hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over the arrays. The parent droplets are moved by various droplet actuation principles. Also, a method using two plates placed one top another while being separated by a spacer. One plate is dedicated to confirming and guiding parent droplets by using hydrophilic patches in a hydrophobic matrix, while the other plate contains HIH arrays for printing of the droplets.

  • Patent number: 10829528
    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 a (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 GABABR1sa beneficial in neurological and psychiatric disorders. The invention as well provides methods and (high content) screening assays for the production of said compounds.

  • Patent number: 10767182
    Abstract: The present application relates to the field of cancer, particularly that of cancers with high MDM4 protein levels (such as melanoma, breast, colon or lung cancers, glioblastoma, retinoblastoma, etc.). It is shown herein that direct and selective inhibition of MDM4, e.g., by antisense RNA, leads to growth inhibition of cancer cells and sensitization to chemo or targeted therapies. Also provided are simple ways of determining which patients are most amenable for such treatment by comparing specific transcript levels.

  • Patent number: RE48801
    Abstract: This disclosure relates to the field of cancer, particularly the field of melanoma. It was found that a particular long non-coding RNA (lncRNA) is specifically up-regulated in melanoma (but not other tumor) cells as compared to melanocytes. Inhibition of this lncRNA in melanoma cells leads to induction of apoptosis and is a novel therapeutic strategy in the treatment of melanoma.

  • Patent number: RE48856
    Abstract: The application relates to the field of cancer, particularly to the field of solid tumors. It was found that a particular long non-coding RNA (lncRNA), NEAT1, an essential architectural component of nuclear paraspeckles, is required for the survival of cancer, but not that of normal, non-transformed, cells. Inhibition of NEAT1 reduces cell viability of cancer cells and induces apoptosis. These data identify NEAT1 as a novel therapeutic target for treatment of solid tumors.
