Abstract: Apelin receptor modulators can improve physical performance, slow progression of age-related frailty, and can reduce age-related muscle weakness in human patients. This disclosure provides methods for treating muscle conditions using a particular class of apelin receptor modulators (e.g., agonists). The muscle condition can be an age-related muscle condition. Also provided is a method for maintaining and/or increasing muscle mass, muscle function, and/or muscle strength in an elderly subject by administration of the apelin receptor modulator. In some embodiments, the apelin receptor modulator (e.g., agonist) is BGE-105, or a pharmaceutically acceptable salt thereof.

Abstract: Systems and methods for secure payment processing are disclosed. An issuer vault generates payment items, which correspond to consumer account information and which replicate the structure of the account information but do not include consumers' actual account number. The payment items, rather than the actual account information, are communicated to on-line and mobile payment services for use by consumers in payment transactions. When a consumer uses a payment item in a payment transaction and the transaction undergoes authorization processing, the payment authorization network uses the payment item to request and receive the actual account information from the issuer vault. The authorization network uses the actual account information for the limited use of authorizing the transaction. Once the transaction has been authorized using the actual account information, the processing of the transaction continues using the payment item information rather than the actual account information.
