[Problem] Provided is a method for detecting of an autofluorescence Liquid Biopsy of Methylated Fragmented DNA (fragmented nucleosome) released into the blood by cell apoptosis as a disease-related substance

[Solution] The inventive method comprises a) a step of capturing the fragmented DNA (fragmented nucleosome) in the analyte as a disease-related substance onto the plasmonic metal meso-crystals; b) a step of irradiating the captured fragmented DNA (fragmented nucleosome) on the plasmonic metal meso-crystal with excitation light to enhance the autofluorescence by the surface plasmon enhancing effect, and acquiring a fluorescent colony image via a filter in a longer wavelength range than the excitation light filter; c) a step of adopting a pixel that exhibits a brightness greater than or equal to a predetermined threshold value of said fluorescent colony image; d) calculating a ratio of a total area value of pixels greater than or equal to a predetermined threshold value of a different two-wavelength region of the adopted measurement region.

In a general aspect, a swab sample is analyzed, for example, to test for disease. In some examples, a swab head of a swab sample is inserted through an opening into an internal reservoir of a sampling device. The sampling device includes the opening, an inlet channel, an outlet channel, and the internal reservoir. The internal reservoir is in fluid communication with the inlet channel, the outlet channel, and the opening. A liquid solvent is supplied to the swab head in the internal reservoir via the inlet channel of the sampling device. The swab head is held in the liquid solvent for a period of time to form an analyte in the internal reservoir. The analyte is extracted from the internal reservoir via the outlet channel of the sampling device. The analyte is transferred to and processed by a mass spectrometer to obtain mass spectrometry data.

Devices and methods to measure cells and/or tissue's contractile force are disclosed. Included is a mount with rigid, and non-rigid posts sized to flex. Determined is force exerted by contractile cells and tissues in a multiwell plate. The device is designed to fit inside individual wells with posts directed downwards. Posts are attached to a 3D printed circular mount with tabs for depth within the well. The mount has a window for medium changes while the device is positioned inside the well. The cells are seeded within a hydrogel. As the hydrogel condenses, cells/tissue wrap around the post's outside pulling non-rigid post toward rigid post. Inverted light microscope is used to determine deflection of non-rigid post inside the multiwell plate. Movement of the non-rigid post is measured using an acrylic ruler on an underside of the multiwell plate. Contractile forces of cells/tissue are determined using cantilever mechanics.

Methods for selecting and treating patients with active Systemic Lupus Erythematosus (SLE) that are predicted to have an increased likelihood of having a positive response to a treatment with a safe and effective amount of an anti-IL-12/IL-23p40 antibody or an anti-IL-23 antibody, e.g., informs on what patients to treat with the anti-IL-12/IL-23p40 antibody ustekinumab.

Cancer treatment using TTFields (Tumor Treating Fields) can be customized to each individual subject by obtaining cancer cells from the subject, determining an electrical characteristic (e.g., dielectrophoretic forces, cell membrane capacitance, etc.) of the cancer cells, determining a frequency for the TTFields based on the determined electrical characteristic, and treating the cancer by applying TTFields to the subject at the determined frequency. In addition, cancer treatment can be planned for each individual subject by obtaining cancer cells from the subject, determining an electrical characteristic of the cancer cells, predicting whether TTFields would be effective to treat the cancer based on the determined electrical characteristic, and treating the subject by applying TTFields if the prediction indicates that TTFields would be effective.

A sensor performs measurement of a culture medium and is used in a state of being immersed in a medium placed in a well, the sensor comprising a main body having a first surface and a second surface that is on the opposite side from the first surface; an electrode unit that is provided on the first surface in the main body and to which a specific voltage is applied in the course of performing measurement in a state of being immersed in the medium; and a liquid holding portion that is provided around the electrode unit on the first surface, and that is disposed near the inner wall surface of the well and holds the medium up to above the electrode unit, in between the inner wall surfaces.
