Abstract: The present invention provides methods for producing high resolution crystals of ribosomes and ribosomal subunits as well as the crystals produced by such methods. The x-ray diffraction patterns of the crystals provided by the present invention are of sufficiently high resolution for determining the three-dimensional structure of ribosomes and ribosomal subunits, for identifying ligand binding sites on ribosomes and ribosomal subunits, and for molecular modeling of ligands which interact with ribosomes and ribosomal subunits. The present invention provides methods for identifying ribosome-related ligands and methods for designing ligands with specific ribosome-binding properties. Thus, the methods of the present invention may be used to produce ligands which are designed to kill or inhibit any specific target organism(s).

Abstract: The invention provides methods for producing high resolution crystals of ribosomes and ribosomal subunits as well as crystals produced by such methods. The invention also provides high resolution structures of ribosomal subunits either alone or in combination with protein synthesis inhibitors. The invention provides methods for identifying ribosome-related ligands and methods for designing ligands with specific ribosome-binding properties as well as ligands that may act as protein synthesis inhibitors. Thus, the methods and compositions of the invention may be used to produce ligands that are designed to specifically kill or inhibit the growth of any target organism.

Abstract: A passenger lift (10) is provided for loading a passenger (12) into and out of an aircraft (14). Lift (10) includes a chassis (38) having a front (34) end and a back (36) end. A plurality of wheels (62 and 63) are attached to the chassis (38) providing means for moving the lift (10). The lift (10) also includes an electrical energy source (70) for providing electrical energy, and an energy converter (104) for translating the electrical energy from the electrical energy source (70) to mechanical energy. The lift (10) includes a rear support (40) generally perpendicular to the chassis (38) and attached to the back end of the chassis (38). The lift (10) has a basket (48) for holding the passenger (12) while the passenger is raised and lowered with the lift (10) and (48) is located at the front end of the chassis (38). The lift (10) includes a pair of lift arms (44) for lifting the basket (48), and a pair of stabilizing arms (42) for providing stability to the basket (48).

Abstract: Improved animal diets for oral administration are provided which include a quantity of non-hydrolyzed, non-digested, naturally occurring protein supplemented with a minor amount of an additive selected from the group consisting of di- and tripeptides including an essential amino acid residue. The diets commonly include at least about 8% by weight of such intact protein, which may be derived from typical plant or animal sources. The preferred additive includes an essential amino acid residue selected from the group consisting of lysine, methionine, threonine, tryptophan, isoleucine and valine. Use of the di-and tripeptide additives of the invention gives increased nitrogen use by the animal, as compared with feeding of the amino acid constituents of the additives.
