Abstract: The present invention belongs to the technical field of liquid crystal materials, and in particular relates to a negative liquid crystal composition and a liquid crystal display element or liquid crystal display containing the liquid crystal composition. The present invention discloses a negative dielectric nematic liquid crystal composition, comprising a compound represented by Formula I, one or more compounds represented by Formula II, and one or more compounds represented by Formula III. The liquid crystal composition has a relatively low rotational viscosity (?1), a high clearing point (Cp), a good solubility and a high stability to heat and light (VHR) on the basis of maintaining an appropriate optical anisotropy (?n), and can be used for developing a liquid crystal display element or liquid crystal display with a low cell thickness, a wide temperature for display, and a fast response.

Abstract: Antibodies that bind to connexin 43 hemichannels and inhibit, or activate, channel opening are provided. In certain aspects, methods for detecting or treating cancers with antibodies that activate Cx43 channel opening are also provided. Likewise, methods for treating inflammatory diseases (e.g., osteoarthritis) and neurological injuries (e.g., spinal cord injury) with antibodies that inhibit Cx43 channel opening are provided.

Abstract: A burglarproof lamp includes a lamp head part with a lamp head shell, a center contact bolt, a center contact insulation fixing base, a center contact insulation fixing sheet, a location post and a connection part fixing base. The center contact bolt is connected to a conductive pole after passing through the center contact insulation fixing base, the lamp head shell and the center contact insulation fixing sheet. The connection part fixing base has a boss and a containing cavity where a spring and a center conductive shaft are located. A conductive fixing ring is connected to the lamp head shell for limiting the position of the connection part fixing base via the boss. The center contact insulation fixing sheet has a location hole, into which the location post can be inserted when it is driven to the position corresponding to the location hole by the connection part fixing base.
