Abstract: Provided are a system and method to culture human cardiac muscle tissues in a bioreactor comprising a plurality of culture wells arranged linearly between two carbon electrodes that are exposed within each well; and two horizontal parallel flexible pillars extending from each well wherein the pillars in each well are configured to suspend an engineered tissue. Also provided is method for diagnosing myocarditis in a subject by analyzing human cardiac muscle tissues cultured in the bioreactor in the presence of blood serum or antibodies from the subject.

Abstract: A color measurement system includes a hand held color measurement instrument, which may be provided with a wireless interface to a computer. The color measurement system includes a scanning guide for holding the hand held color measurement instrument in proper alignment with a color target. The scanning guide includes a calibration reference to allow convenient calibration of the hand-held color measurement instrument. The hand-held color instrument includes an illumination ring to provide visual feedback to the user. The color of the illumination ring changes in order to display a color similar to that being read by the hand-held color measurement instrument. Color management profiling of the hand held color measurement instrument illumination ring improves the color rendition capability of the illumination ring.
