  • Publication number: 20230411006
    Abstract: The area under the curve (AUC) of an immunosuppressant is the best exposure marker for following the global exposure to an immunosuppressant in an organ of a subject. However, measuring AUC is complicated in routine care as it requires multiple blood samples during the dosing interval, which can be expensive and clinically impractical. The present invention proposes to use artificial intelligence technique to predict AUC values based on the value of some predictors. Such method conducts to surprisingly accurate results. Notably, the method enables to obtain satisfactory results with only two samples.

  • Publication number: 20220091033
    Abstract: There is described a method for determining a refractive index of a medium. The method generally has providing a substrate having a surface, the surface having a first surface portion and a second surface portion spaced-apart from the first surface portion and recessed of a depth relative to the first surface portion; receiving the medium at least on the second surface portion; propagating a first optical beam towards the first surface portion and a second optical beam towards the second surface portion; collecting the first and second optical beams after said propagating and generating first and second signals being indicative of a phase of a respective one of the first and second collected optical beams; and determining a refractive index of said medium based on the first and second signals, the depth, a wavelength associated to the first and second optical beams and a refractive index of the substrate.

  • Publication number: 20220081715
    Abstract: The invention relates to methods for diagnosing or determining in a subject who underwent a solid organ transplantation the risk of developing graft rejection other than T cell mediated, comprising the steps of: measuring in a peripheral blood sample from said subject the RNA expression levels of a set of genes comprising at least CXCL10, FCGR1A, FCGR1B and TEMP1; determining from the measured expression levels of said set of genes, an expression profile; comparing the determined expression profile of said subject with a reference expression profile; and determining from said comparison, whether said subject is experiencing said rejection or has an increased risk of developing said rejection.

  • Patent number: 8885174
    Abstract: Apparatus and method are provided for monitoring and measuring matter and energy fluxes by use of devices able to detect refractive index changes. In one aspect, apparatus use an interference between two electromagnetic radiations in order to provide high sensitivity, enabling fluxes monitoring at the microscopic scale, by measuring phase changes or Optical Path Length (OPL) changes. In one aspect, methods are provided for monitoring and measuring the electrical activity of a biological cells, simultaneously on several cells, without use of electrodes and contrast agents.

  • Patent number: 7649160
    Abstract: A new way of mixing instrumental and digital means is described for the general field of wave front sensing. The present invention describes the use, the definition and the utility of digital operators, called digital wave front operators (DWFO) or digital lenses (DL), specifically designed for the digital processing of wave fronts defined in amplitude and phase. DWFO are of particular interest for correcting undesired wave front deformations induced by instrumental defects or experimental errors. DWFO may be defined using a mathematical model, e.g. a polynomial function, which involves coefficients. The present invention describes automated and semi-automated procedures for calibrating or adjusting the values of these coefficients. These procedures are based on the fitting of mathematical models on reference data extracted from specific regions of a wave front called reference areas, which are characterized by the fact that specimen contributions are a priori known in reference areas.

  • Patent number: 6943924
    Abstract: The present invention is related to a method for performing digital holographic imaging (DHI), said DHI being characterized by the fact that images of a sample are obtained by applying numerical means to reconstruct holograms of the sample. In the method of the invention, the sample is in a medium with controlled properties that influence the behaviour of the sample, and/or that influence the process of hologram formation. The information content of one hologram, or of a plurality of holograms, recorded with the sample in one medium, or in a plurality of medium, is used to reconstruct one image of the sample, or a plurality of images of the sample, that describe quantitatively one property of the sample, or a plurality of properties of the sample. The present invention is also related to an apparatus with which to perform said method.

  • Patent number: 4731596
    Abstract: This highly reproducible stripline band-pass filter comprises, between its two leads (A and B), n halfwave resonators (1-7) connected in series. Suitable capacitors (C0-C7) provide a powerful coupling between the successive elements of the series circuit. Quarterwave resonators (10, 11, 70, 71) each having one end connected to the series circuit provide a steep-edge amplitude/frequency response at the limits of the pass-band of the hyperfrequency, wideband filter so obtained.
