Abstract: Compositions and methods for treating striated muscle injury, treating striated muscle atrophy, and/or for promoting striated muscle growth are provided and include administering zinc oxide nanoparticles to a subject in need thereof. The zinc oxide nanoparticles can be adminstered before, during, and/or after exposure to an injurious stimuli, such as radiation. Administration of the zinc oxide nanoparticles reduces activation of autophagy regulators, increases striated muscle anabolism, increases DNA repair signaling, and/or increases striated muscle protein synthesis and growth.

Abstract: Compositions and methods for treating striated muscle injury, treating striated muscle atrophy, and/or for promoting straited muscle growth are provided and include administering zinc oxide nanoparticles to a subject in need thereof. The zinc oxide nanoparticles can be adminstered before, during, and/or after exposure to an injurious stimuli, such as radiation. Adminstration of the zinc oxide nanoparticles reduces activation of autophagy regulators, increases striated muscle anabolism, increases DNA repair signaling, and/or increases striated muscle protein synthesis and growth.

Abstract: Methods for treating sepsis are provided and include the administration an effective amount of cerium oxide nanoparticles to a subject in need thereof. The sepsis being treated can include polymicrobial sepsis and can include the administration of about 0.1 mg/kg to about 1.0 mg/kg of the cerium oxide nanoparticles. The administration of the cerium oxide nanoparticles further allows one or more of the symptoms of sepsis to be treated. Methods of treating an inflammatory disorder that make use of cerium oxide nanoparticles are further provided.
