  • Patent number: 9833475
    Abstract: Techniques and devices for removing (filtering out) unwanted/inhibitory components (for example, products, byproducts and/or cell output such as inhibitory catabolic proteins) from a composition (for example, autologous fluid or serum) containing such unwanted/inhibitory components. The devices include at least one construct designed to contain a composition (for example, autologous fluid or serum) containing inhibitory/unwanted components (products, byproducts and/or output of cells such as inhibitory catabolic proteins). The construct is provided with interior walls including specific protein capturing means designed to remove the inhibitory/unwanted component(s) (for example, specific protein(s)) from the composition. Proteins targeted for capture include, but are not limited to, catabolic cytokines such as IL-1?, IL-?, IL-6, TNF?, IFN? and MMPS as these proteins inhibit the healing process.

  • Patent number: 9690086
    Abstract: A widefield microscope illumination system and method with a microscope objective and an illumination light source that sends widefield illumination light along illumination beam paths. Illumination light penetrates into the microscope objective through illumination light entry sites located within a predetermined annular or annular-segment-shaped illumination light entry area having a large offset to an optical objective axis of the objective. A spatially resolving light detector detects light sent from an illuminated sample through the microscope objective along a detected light beam path. An automatic illumination light beam path manipulation device is controlled by a control system, which is arranged in front of the microscope objective in relation to the direction of the illumination light beam path, and by means of which illumination light beam path manipulation device the illumination axes are automatically movable at time intervals to a plurality of different illumination light entry sites.

  • Patent number: 9618449
    Abstract: Modular systems can be used for optical analysis, including in-situ analysis, of stimulated liquids. An excitation module can include a radiation sources, e.g., a laser, LED, lamp, etc. A detection module can include one or more detectors configured to receive spectral and/or temporal information from a stimulated liquid. Such systems can be used to identify or measure optical emissions including fluorescence or scattering. The efficient excitation of liquid samples and collection of emissions from the samples provides substantial, up to four-fold increase in the emission signal over prior systems. In an example, emission measurements can be conducted in an isolated sample compartment, such as using interchangeable modules for discrete sampling, flow-through sampling, or sampling via fiber probe. The systems and methods described herein can be used to characterize natural aquatic environments, including assessments of phytoplankton pigments, biomass, structure, physiology, organic matter, and oil pollution.
