Abstract: A liposome composition containing encapsulated compound in stable precipitated form, and a method for producing the composition, are disclosed. The concentration of precipitated compound within the liposomes is severalfold higher than that in the bulk medium, and the concentration of compound within the liposomes is not reduced in the presence of a proton or alkali metal-ion ionophore added to the suspension.

Abstract: The present invention provides, inter alia, formulations useful to ameliorate symptoms associated with mucosal abrasions, specifically those due to dental orthodontic brackets; oral surgery; periodontal surgery or other procedures. For instance, there is a formulation comprising: 65 to 75% microcrystalline wax; 5 to 15% non-ionic polymer; 15 to 25% topical anesthetic; and 1 to 5% surfactant, wherein the ratio of non-ionic polymer to microcrystalline wax is no greater than 0.2. Preferably, for solid topical anesthetics, the particle size is less than the apertures of a 100-mesh screen. However, the topical anesthetic may also be a liquid. Formulations wherein the mixture is a homogeneous matrix is preferred.

Abstract: The present invention comprises a material and a method of its preparation. The material may be described as hydrophilic microparticles, comprising a cluster of organic substance with a layer of polyelectrolyte on its surface. The present invention establishes an improved method for preparing aqueous colloidal dispersions of water-insoluble organic substances using polyionic hydrophilic polymers by which the stability of the suspension is maintained after removal of the stabilizing and/or solubilizing medium of the drug. This improved method can be utilized to formulate a variety of water-insoluble organic substances.

Abstract: The present invention relates generally to a non-toxic lipid conjugated with a cationic amino acid containing a guanidino group. Specifically, the naturally-occuring lipid DOPE is combined with the naturally-occurring amino acid Arginine. These compounds are useful for encapsulating and delivering pharmaceuticals and poly and oligonucleotides. These compound improve over current compounds, because they are composed of non-toxic and, in the case of Arg-DOPE, natural components, and therefore result in minimal unwanted side effects. Methods of use of the cationic lipids are also claimed.

Abstract: The present invention provides 12 different sequences for soybean .beta.-1,3-glucanases and the proteins for which they encode. Also provided are methods for the utilization of knockout mutants of the sequences which are useful for engineering genic male-sterile plants. Other methods and materials related to these sequences are also provided.

Abstract: The present invention provides bradykin antagonists containing pentafluorophenylalanine which are therapeutically useful. Moreover, the present invention provides methods to antagonize bradykinin receptors in a mammal in need of such antagonism, comprising administering a bradykinin antagonist containing pentafluorophenylalanine. Also provided are methods to treat inflammation in a mammal in need of such inhibition, comprising administering a bradykinin antagonist containing pentafluorophenylalanine. Lastly, a method to treat cancer in a mammal in need of such inhibition, comprising administering a bradykinin antagonist containing pentafluorophenylalanine.
