Abstract: A humeral implant is provided. The implant includes a humeral stem including a plurality of fins. At least one fin comprises a serrated bottom edge. A radial distance between an inner bottom edge of the at least one fin and a centerline of the humeral implant increases along a distal length of extension of the at least one fin. At least the serrated bottom edge of the at least one fin is configured to cut into and compact bone of the metaphysis of a humerus toward relatively denser cancellous bone of a peripheral portion of the humerus when press-fit therein, thereby providing sufficient press-fitting for cementless fixation of the humeral stem into the humerus. Related kits and methods are also provided.

Abstract: The invention provides for improved multi-well plates and platforms that comprise a plurality of wells having increased volume capacity and clustered in a standard multi-well plate format and dimensions, said multi-well plate format being compatible with auxiliary equipment currently used and designed for the particular multi-well plate format. More particularly, the invention provides improved multi-well plates comprising a base to improve wells having one or more said wells having rectangular configuration, better retention of working materials and tissue culture ingredients than observed in conventional round-shaped wells. A cover is provided for protecting the assembly and cell cultures.

Abstract: An orchid cultivating device, which includes a flat base plate, and two guard members fastened to the flat base plate to hold sphagnum moss and orchids, wherein the base plate has a plurality of retainer rods, a plurality of clamps holding a spray tube at the top side, and a water trough for connecting excessive water; the guard members each have a plurality of arched ribs defining a plurality of open spaces for ventilation, and a plurality of peripheral mounting lugs respectively engaged with the retainer rods at the base plate. The base plate and the guard members can be injection-molded from plastics to reduce the manufacturing cost. Hanger means can be fastened to through holes at the base plate for carrying by hand, or hanging on a high place.
