Abstract: Pharmaceutical compositions including a mitochondria-targeting polypeptide and a therapeutic agent coupled to the mitochondria-targeting polypeptide are provided. Methods of treating a subject in need thereof including administering a therapeutically effective amount of the pharmaceutical composition to the subject are provided. The subject may have an aging-related condition, heart failure, diabetes, myocardial infarction, acquired mitochondrial disorder, and/or inherited mitochondrial disorder. Methods of delivering compound to a mitochondrion and of preparing a compound for delivery to a mitochondrion are also provided. Furthermore, biological tracers including a mitochondria-targeting polypeptide and a label coupled to the mitochondria-targeting polypeptide are provided.

Abstract: Methods for treating patients having a cardiomyopathy are provided. Additionally, methods for prophylactically treating patients at risk of developing a cardiomyopathy are provided. Methods for treating patients having, or at risk of developing, a cardiomyopathy may comprise administering a fusion protein including a tafazzin peptide and a cellular permeability peptide to the patient. Further, the tafazzin peptide may be coupled to the cellular permeability peptide by a polypeptide linker.

Abstract: Fusion proteins comprising a tafazzin peptide and a cellular permeability peptide are disclosed. The tafazzin peptide may be coupled to the permeability peptide through a polypeptide linker. Methods of making and using the fusion proteins are also disclosed. For example, the disclosed fusion proteins may be used to treat a patient having a disorder associated with a tafazzin deficiency or a remodeled cardiolipin deficiency (e.g., Barth syndrome). Additionally, the disclosed fusion proteins may be used in prophylaxis against developing a disorder associated with a tafazzin deficiency or a remodeled cardiolipin deficiency in a patient at risk of developing such a disorder.

Abstract: A method to guarantee bandwidth for a terabit multiservice switch including receiving control cells indicating that a destination port of an asynchronous transfer mode (ATM) network is congested, and reducing incoming traffic to the congested port to a guaranteed bandwidth of traffic until the destination port is uncongested, is disclosed.
