    Abstract: A diprovocim compound that corresponds in structure to structural Formula V is disclosed, wherein A, W, Z, R1, R2, R3 and R4 (when present) are defined within. A diprovocim compound has immune-adjuvant properties on human and mouse cells in culture and on in vivo immunization of mice. A composition containing a diprovocim and a method of using a compound are also disclosed. The immunostimulatory activity of a diprovocim compound is similar to that of LPS, to which there is no apparent structural similarity. A contemplated compound bears no structural similarity to either the TLR1/TLR2 lipoprotein agonists nor to any other synthetic TLR agonist, and is remarkably easy to prepare and synthetically modify.

    Abstract: This disclosure includes an imaging system that is configured to image in parallel multiple focal planes in a sample uniquely onto its corresponding detector while simultaneously reducing blur on adjacent image planes. For example, the focal planes can be staggered such that fluorescence detected by a detector for one of the focal planes is not detected, or is detected with significantly reduced intensity, by a detector for another focal plane. This enables the imaging system to increase the volumetric image acquisition rate without requiring a stronger fluorescence signal. Additionally or alternatively, the imaging system may be operated at a slower volumetric image acquisition rate (e.g., that of a conventional microscope) while providing longer exposure times with lower excitation power. This may reduce or delay photo-bleaching (e.g., a photochemical alteration of the dye that causes it to no longer be able to fluoresce), thereby extending the useful life of the sample.
