Abstract: Disclosed are methods and compositions related to the production of erythropoietin. The disclosed compositions comprise a poly amino acid. The production of erythropoietin by the disclosed compositions and methods can take place in vivo, in which the proliferation of a subject's erythropoietin-producing cells leads to an increased level of production of erythropoietin, in vitro, in which increased proliferation of cultured erythropoietin-producing cells leads to an increased production of erythropoietin, ex vivo, in which cells or tissues harvested from a subject produce erythropoietin. The disclosed compositions can be administered to a subject or applied to cells or tissues to stimulate increased production of erythropoietin.

Abstract: Disclosed are methods and compositions that are related to the production of erythropoietin. The disclosed compositions generally comprise a poly amino acid, such as a poly amino acid comprising one or more glutamic acid residues. The production of erythropoietin by use of the disclosed compositions and methods can take place in vivo, in which the proliferation of a subject's erythropoietin-producing cells leads to an increased level of production of erythropoietin, in vitro, in which increased proliferation of cultured erythropoietin-producing cells leads to an increased production of erythropoietin, ex vivo, in which cells or tissues harvested from a subject produce erythropoietin. The disclosed compositions can be administered to a subject or applied to cells or tissues to stimulate increased production of erythropoietin.

Abstract: A composition for a guacamole preparation that inhibits spoilage and/or oxidation of the avocado fruit present in the preparation and the discoloration and souring that commonly accompanies oxidation. The inhibitory effect is achieved through the use of a natural antioxidant or preservative that is found in tomatillo. The composition only requires avocado flesh and the pulp of tomatillo as no other chemical preservatives are required to achieve stability of the preparation. The composition may optionally include flavoring additives such as spices, peppers and vegetables and as well as chemical agents for controlling the pH of the composition. A process for preparing the composition is disclosed that includes combining the avocado flesh and tomatillo pulp and heating the mixture prior to sealing it in sterilized containers.
