Abstract: A reflective gun sight includes a rear sight including a light source; and a front sight including a reflective surface that is directly opposing the light source and recessed within an aperture of a front sight housing, wherein light emitted from the light source travels through the aperture and is reflected by the reflective surface toward the rear sight.

Abstract: The present invention is directed to the cells, compositions and methods for the production of recombinant protein, wherein an f-met group on the 5?-terminus is enzymatically removed. In particular, the invention is directed to a production process for obtaining high levels of soluble recombinant CRM197 protein from E. coli. Cells preferably contain one or more mutations of disulfide reductase genes, so that disulfide reductase activity is reduced. The invention also relates to purification method for CRM197 as well as characterization of properly folded CRM197 protein.

Abstract: A method of firing a firearm includes rotating a trigger to force a latch pin lever to move; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

Abstract: A reflective gun sight includes a rear sight including a light source; and a front sight including a reflective surface that is directly opposing the light source and recessed within an aperture of a front sight housing, wherein light emitted from the light source travels through the aperture and is reflected by the reflective surface toward the rear sight.

Abstract: A firearm includes a rail; a mount attached to the rail; a lens attached to and rotatable with respect to the mount; a light source that reflects a light off a reflective surface of the lens to aim the firearm; a hood rotatably mounted and in contact with the lens, wherein the hood folds over the lens in a collapsed configuration and is angled from the lens in a deployed configuration, and the hood and the lens each pivot on respective axes that are parallel to each other.

Abstract: A pistol, incudes a slide; a lens attached to and rotatable with respect to the slide; a light source that reflects a light off a reflective surface of the lens to aim the pistol; a hood rotatably mounted and in contact with the lens, wherein the hood folds over the lens in a collapsed configuration and is angled from the lens in a deployed configuration, and the lens, the light source, and the hood fit within an outline profile of the slide in the collapsed configuration.

Abstract: The invention is directed to methods and compositions for the expression and purification of products such as peptides and proteins in microorganisms. In particular, pre-products are expressed recombinantly, wherein the cytoplasm of the microorganism alters the expressed pre-products to produce products in an active/final or otherwise desirable form. Alterations associated with expression of a desired recombinant product include shifting of the redox state of the cytoplasm to allow proper protein folding, site-directed cleavage of pre-proteins to activate the protein, site-directed cleavage of an unwanted methionine from the N terminus of the protein, and/or one or more ligations to form desired protein configurations, all within the same cell.

Abstract: A method of firing a firearm includes rotating a trigger to force a latch pin lever to move; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

Abstract: This invention provides novel reagents for cyanating polysaccharides in aqueous or part aqueous solutions so that they may be covalently linked to peptides or proteins either directly or through a spacer. These reagents include 1-cyano-4-dimethylaminopyridinium bromide, or a functional derivative or modification thereof. The examples illustrate the use of these reagents with a variety of polysaccharides and proteins showing that the methods are generally applicable.

Abstract: A method of firing a firearm includes compressing a main spring to rotate a latch pin lever; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

Abstract: A reflective sight for use with a firearm includes a rear sight including a light source; and a front sight including a reflective surface directly opposing the light source, where light emitted from the light source is reflected by the reflective surface toward the rear sight. The rear sight can include a plurality of light sources and at least two of the plurality of light sources emit different colors of light.

Abstract: Nasal tracheal devices include a tube with visual indicia of insertion depth corresponding to patient height and an inflatable cuff. The tube comprises or provides a plurality of lumens that are in fluid isolation including an airpath lumen and a pressurized fluid source for inflating the cuff. The devices may also be configured to suction patient fluid from a location adjacent and/or above the cuff.
