摘要:
Technics are known to use vessel bifurcations detection to obtain access to the detection of aneurysms. However, such technics suffer from a relatively poor accuracy. Therefore, the Applicants have developed a specific method for locating and characterizing bifurcations of a cerebral vascular tree based on a graph analysis of a three-dimensional skeleton of the tree. This enables to determine more accurately the vessel bifurcations. Such property can be used advantageously for several applications such as predicting the risk of developing an aneurysm, diagnosing an aneurysm, identifying a therapeutic target, identifying a biomarker or screening a compound.

L'invention concerne, un procédé de détermination d'un risque de rejetdéfinitif d'un greffon après transplantation sur un receveur, caractérisé en ce qu'il comprend les étapes suivantes: (a) introduire de caractéristiques physiologiques/cliniques du receveur et du donneur à l'aide d'une interface d'entrée dans une unité de calcul, lesdites caractéristiques comprenant: -le genre du receveur, -le taux de créatinine du donneur du greffon au moment du prélèvement, -l'âge du receveur du moment de la transplantation, -le nombre de transplantations rénales antérieures que le receveur a reçues, -un taux de créatinine du receveurmesuré à deux au moins un moment déterminé après la transplantation, -un taux de protéinurie du receveurmesuré à un moment déterminé après la transplantation, -l'existence d'un épisode de rejet définitif lors de la première année de la transplantation, (b) déterminer des paramètres à partir desdites caractéristiques, (c) combiner lesdits paramètres afin d'obtenir un score de risque de rejet définitif du greffon, et (d) analyser le dit score de risque afin de déterminer un risque de rejet définitif d'un greffon.
摘要:
The invention relates to a method for the in vitro culture of T cells, in particular of modified or non-modified T cells infiltrating the so-called TIL tumours, from a tumour or blood sampling of the patient suffering from a tumour, said method successively and at least comprising a step of emergence of the T cells contained in the sampled blood or tumour, a step of stimulation of the T cells resulting from the emergence step, and a step of amplification of the stimulated T cells. The method is characterised in that the stimulation of the T cells is carried out in a closed and partitioned culture vessel.
摘要:
The present invention relates to a method for segmenting a digital image, for example to accurately segment cerebral vasculature on MRI-TOF images of a brain. The method first uses a model that imitates the perception of luminance contrasts by a human observer to accentuate a contrast between structures of interest, such as cerebral vasculature, and the image background. Then, the image is thresholded using an adaptive threshold. This enhanced segmentation method can be used to process digital images before launching further machine-implemented characterizations of the structures of interest, such as detecting and characterizing bifurcations of the cerebral vasculature for intra-cranial aneurysm prediction.
摘要:
The invention relates to methods comprising a step consisting of determining the proportion and/or the level of T regulatory lymphocytes with a CD4 + CD8αα low Foxp3 neg phenotype specific for Faecalibacterium prausnitzii for (i) diagnosing, (ii) prognosing outcome of, or (iii) predicting the risk of developing, an inflammatory bowel disease in a patient. The invention also concerns the treatment of an inflammatory bowel disease. The invention further relates to the kits that are useful in the above methods for diagnosing / prognosing an inflammatory bowel disease, and in the treatment of an inflammatory bowel disease. In a particular embodiment, the inflammatory bowel disease is the Crohn's disease.
