In one embodiment, a lid for a vessel has a generally planar body with top side and bottom side, a handle receptacle extending below the bottom side of the generally planar body, and a grasping portion of a handle adapted to fit within the handle receptacle which is rotatably movable between two configurations. Methods of using such aminosterols compounds are also enclosed, including those employing compounds that are inhibitors of a spectrum of NHEs as well as those using compounds that are inhibitors of only one specific NHE. The plurality of light emitting cells are connected in series on the thermally conductive substrate. The second insulation film formed on side surface of the gate structures is removed, exposing the surface of the semiconductor substrate in the vicinity of the gate structures on both sides of the trenches. The rail guide has a convex portion 3d that is located on the side surface 3b of the rail guide, the convex portion extending from the upper surface of the rail guide and being in contact with the second bottom plate 2c of the bottom case. The filter, ball lens and detection module are securely attached and mounted within the interior of the casing.
