Abstract:
Embodiments include systems and methods for summoning help and locating a person, comprising transmitting information over a wireless network in response to a user action; wherein the information includes the geographic location of the user.
Abstract:
Embodiments of this invention include flatbed scanners that have a surface and have a plurality of light sources. Alternatively, a single light source can be moved in two dimensions relative to an object placed on the surface of the scanner. Other embodiments include a scan head that is moveable in two dimensions relative to the flat bed of the scanner. Further embodiments include one or more polarizing filters to reduce glare and increase the quality of a captured image. Theses scanners can be used to capture images of enzyme linked immunosorbent assay (ELISA) substrates, plates having cultures thereon or other objects having irregular lower surfaces. Additional embodiments include methods for capturing images from ELISA substrates, bacterial culture plates, viral plaque assay plates and the like.
Abstract:
Embodiments of the present invention relate to devices and methods for detecting cellular products using detection particles having product-specific detection reagents and having a characteristic spectral feature. In particular, devices and methods are provided for measuring secreted cellular products including cytokines. Detection substrates, include microwells having product-specific capture reagents thereon or comprising hydrophobic membranes are described having greater capability to detect products from individual cells in a mixture of heterogeneous cells. With the use of multiple detection particles, multiple cellular products can be detected in a single well. Additionally, using the inherent spectral properties of detection particles, no enzymatic reactions are needed to visualize a secreted product, thereby increasing the sensitivity, reproducibility and ease of use.

Abstract:
Embodiments of this invention include methods for detecting in vitro the presence in peripheral blood mononuclear cells (PBMCs), and in serum or plasma, of antibodies reactive to and of lymphocytes that are responsive to CNS antigens associated with Multiple Sclerosi (MS). These CNS antigens include, but are not limited to whole brain lysate and the myelin antigens myelin basic protein (MBP), myeli oligodendrocyte glycoprotein (MOG), MOG peptides (MOGps), proteolipid protein (PLP), and PLP peptides (PLPps). Stimulating PBMCs from patients with MS by CNS antigens cause B-lymphocytes to produce antibodies specific for CNS antigen, and causes T-lymphocytes to produce T-lymphocyte-specific cytokines, including interferon gamma (IFN-y), interteukin-2 (IL-2), or interleukin-17 (IL-17). In contrast, stimulating PBMCs from subjects without MS do not produce such responses.
