Abstract:
An optical engine for use in a bench top flow cytometer, the optical engine comprising a set of lasers; a different set of beam shaping optics for each laser, wherein each set comprises two lenses to adjustably focus light horizontally along an x-axis to a same horizontal position and vertically along a y-axis to a different vertical position along a same plane; collection optics for collecting fluorescence from the flow cell; filtration optics that filter the collected fluorescence from the flow cell into different detection channels according to wavelength ranges; and a detector for each detection channel that converts the filtered fluorescence to electrical signals, wherein electrical signals are processed so that the fluorescence from each laser at the different vertical positions is distinguished at the same detector.
Abstract:
Novel compounds having a fused bicyclic hetero aromatic ring system substituted with a heteroaryl five-membered ring are disclosed. The compounds inhibit growth of a variety of types of cancer cells, and are thus useful for treating cancer. Efficacy of these compounds is demonstrated with a system for monitoring cell growth/migration, which shows they are potent inhibitors of growth and/or migration of cancer cells. In addition, compounds of the invention were shown to stop growth of tumors in vivo, and to reduce the size of tumors in vivo. Compositions comprising these compounds, and methods to use these compounds and compositions for treatment of cancers, are disclosed.
Abstract:
A device for monitoring the migration or invasion of a biological particle such as a cell is disclosed. The device includes an upper chamber adapted to receive and retain a cell sample, a lower chamber having at least two electrodes, and a biocompatible porous membrane having a porosity sufficient to allow cells to migrate therethrough. The membrane is disposed in the device so as to separate the upper and lower chambers from one another. Migration of cells through the porous membrane permits contact between the migrating cells and one or more electrodes of the lower chamber. The contact provides a detectable change in impedance between or among the electrodes.

Abstract:
A device for detecting cells and/or molecules on an electrode surface is disclosed. The device detects cells and/or molecules through measurement of impedance changes resulting from the cells and/or molecules. A disclosed embodiment of the device includes a substrate having two opposing ends along a longitudinal axis. A plurality of electrode arrays are positioned on the substrate. Each electrode array includes at least two electrodes, and each electrode is separated from at least one adjacent electrode in the electrode array by an expanse of non-conductive material. The electrode has a width at its widest point of more than about 1.5 and less than about 10 times the width of the expanse of non-conductive material. The device also includes electrically conductive traces extending substantially longitudinally to one of the two opposing ends of the substrate without intersecting another trace. Each trace is in electrical communication with at least one of the electrode arrays.
Abstract:
The present invention relates to pharmaceutical compounds, compositions and methods, especially as they are related to compositions and methods for the treatment and/or prevention of a proliferation disorder, a cancer, a tumor, an inflammatory disease, an autoimmune disease, psoriasis, dry eye or an immunologically related disease, and in some embodiments diseases or disorders related to the dysregulation of kinase such as, but not limited to, EGFR (including HER), Alk, PDGFR, BLK, BMX/ETK, FLT3(D835Y), ITK, TEC, TXK, BTK, or JAK, and the respective pathways.
Abstract:
Devices and methods for performing extracellular recording of cells, such as excitable cells, cardiomyocytes, and cardiomyocyte precursor cells is provided. An exemplary device includes a nonconductive substrate forming or provided as a base of one or more wells; a recording electrode positioned on the substrate within the well, wherein the recording electrode is accessible to cells when a cell sample is added to the device; and a reference electrode positioned within the well in a cell-free zone, the cell-free zone characterized as free from contact with cells when the cell sample is added to the device, thereby preventing contact between cells and the reference electrode.
