Abstract:
The present invention provides substituted di-, tri-, tetra- and penta-sulfide compounds and compositions, and methods of using the same for the treatment and/or prevention of a cell proliferative disorder. The present invention also provides methods for preparing trisulfide compounds and compositions.
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:

Abstract:
A prism including a substrate faceted to provide a plurality of flat surfaces, wherein at least two of the plurality of surfaces, each including a filter coating, form at least two filter surfaces, wherein each filter surface selectively permits passage of a predetermined wavelength and reflects remaining wavelengths along an optical path towards another of the plurality of surfaces, optionally another filter surface, wherein an angle of incidence of each of the plurality of surfaces along the optical path is equal or nearly equal. An apparatus incorporating the prism and its use for splitting a light spectrum into a plurality of wavelengths or wavelength ranges.
Abstract:
Systems and methods for improved monitoring of excitation-contraction coupling and excitable cells are provided, which provide millisecond time resolution. The system is capable of continuously monitoring excitation-contraction coupling in a relatively high-throughput manner. The system includes a device for monitoring cell-substrate impedance, an impedance analyzer capable of impedance measurements at millisecond time resolution, electronic circuitry that can engage the device and selectively connect two or more electrode arrays of the device to the impedance analyzer and a software program that controls the electronic circuitry and records and analyzes data obtained from the impedance analyzer.
