    摘要: Early stage, rapid, low-cost, and accurate detection of disease components in a biological fluid is critically important. A point of care device can use functionalized magnetic beads to facilitate this detection. The device can include a sample holder with a collection region. A magnet can be used to draw the functionalized nanoparticles bound to the disease component into the collection region, where the disease component is captured. A light source can shine a light beam through the collection region; and a detector can detect the light beam after traversing the collection region to determine whether the disease component is present in the sample.

    摘要: An agent for use in detecting, monitoring, and/or imaging cancer cells and/or cancer cell metastasis, migration, dispersal, and/or invasion, and/or for treating cancer in a subject includes a targeting peptide and at least one of a detectable moiety, therapeutic agent, or a theranostic agent that is directly or indirectly linked to the targeting peptide. The targeting peptide specifically binds to and/or complexes with a proteolytically cleaved extracellular fragment of an immunoglobulin (Ig) superfamily cell adhesion molecule that is expressed by a cancer cell or another cell in the cancer cell microenvironment.

    摘要: Early stage, rapid, low-cost detection of disease components in a biological sample is critically important. A point of care device can include a collection region and can be used to hold a sample that is combined with a fluorescent dye and a plurality of magnetic particles such that disease components in the sample are tagged with the fluorescent dye and the plurality of magnetic particles. At least one magnet can be located next to the collection region to establish a magnetic field gradient to draw the tagged disease components into the collection region from the device. A fluorescence microscope can image the small collection region based on the fluorescent dye to detect the disease components. The fluorescence microscope uses light to excite the fluorescent dye and a filter to transmit light emitted by the fluorescent dye to the fluorescence microscope, while restricting light used to excite the fluorescent dye.

    摘要: A system and method is provided for operating a high-field magnetic resonance (MR) system includes performing a series of data acquisition modules without respiratory gating. Each data acquisition module is formed of a steady-state free precession pulse sequence. Performing the series of data acquisition modules includes varying at least one of an amplitude of an excitation pulse or a repetition time of the steady-state free precession pulse sequence between adjacent data acquisition modules in the series of data acquisition modules to acquire a series of MR data with random or pseudo-random imaging acquisition parameters. The series of MR data is compared to a dictionary of signal evolution profiles to determine a match between the series of MR data with at least one signal evolution profile in the dictionary indicating at least one quantitative parameter in the subject.

    摘要: Example apparatus and methods concern determining whether a target material appears in a region experiencing nuclear magnetic resonance. One method acquires a baseline value for a magnetic resonance parameter (MRP) while the region is not exposed to a molecular imaging agent that affects the MRP, acquiring a non-specific uptake value for the MRP while the sample is influenced by a non-specific molecular imaging agent and acquiring a specific uptake value for the MRP while the sample is influenced by a specific molecular imaging agent. The non-specific masking problem is solved by characterizing the region as a function of the baseline value, the non-specific uptake value, and the specific uptake value. The function relies on the similarities and differences between non-specific uptake of the non-specific molecular imaging agent, non-specific uptake of the specific molecular imaging agent, and specific uptake of the specific molecular imaging agent.
