Polypeptides with superoxide dismutase activity of bacterial origin are useful in animal feed additives for improvement of animal growth and performance and in improving animal health, particularly animals exposed to environmental or heat stress.

The present disclosure relates to dietary supplements, for improving dermatological health. In embodiments, the composition is comprised of D-Biotin, grape seed extract, superoxide dismutase, zinc, Vitamin C, Lactobacillus plantarum, Lactobacillus reuteri, Lactobacillus rhamnosus, or combinations/sub-combinations thereof.

The invention is directed to a method of treating a spinal cord injury, a neurodegenerative disease or a neuronal injury in an individual in need thereof comprising administering an effective amount of superoxide dismutase (SOD) and catalase to the individual, wherein the superoxide dismutase and the catalase are encapsulated in one or more nanoparticles that release the SOD and catalase upon administration. Another aspect of the invention is directed to compositions comprising superoxide dismutase (SOD) and catalase encapsulated in one or more nanoparticles.

The invention provides topical compositions and methods for using the compositions. The compositions can be used for the treatment of fibrotic or connective tissue disorders involving scarring, sub-dermal plaque accumulations, or fibrosis of muscle tissue. The disorders can be painlessly treated by the topical application of a composition described herein. One or more calcium channel blocker agents can serve as an active ingredient of the compositions, optionally in combination with, for example, one or more of emu oil and superoxide dismutase. The composition can further include pharmaceutically acceptable carriers that can facilitate the non-invasive transdermal delivery of the active(s) to subdermal sites.

The present invention relates to compositions comprising exosomes and biological agents and methods of using the compositions for the delivery of biological agents to cells and to subjects.

Described herein are methods and compositions for the use of treating damage induced by SD. Aspects of the invention relate to administering to a subject in need thereof an agent that reduces reactive oxygen species. In some embodiments, administration of an agent that reduces reactive oxygen species repairs SD-induced damage in the gut.

Genetically engineered bacteria, pharmaceutical compositions thereof, and methods of treating or preventing autoimmune disorders, inhibiting inflammatory mechanisms in the gut, and/or tightening gut mucosal barrier function are disclosed.

Novel superoxide dismutases of fungal origin are active, gastric stable and thermal stable, and effective for use in animal feed additives. The use of superoxide dismutase in animal feed improve animal growth, animal health and intestinal health of animals.
