The present invention relates to adeno-associated viral (AAV) particles encoding siRNA molecules and methods for treating amyotrophic lateral sclerosis (ALS).

Disclosed herein are compositions containing an effective amount of a NiSOD or a derivative thereof useful as a prophylactic treatment for hair graying or follicle degeneration. Also disclosed here are methods for treating or mitigating hair graying and/or follicle degeneration.

Animal feeds are preserved using an enzymatic antioxidant. Polypeptides having catalase activity and/or superoxide dismutase activity preserve animal feed or animal feed additives or prevent the degradation of the proteins, vitamins fats and lipids contained in animal feed components.

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.

Provided is a test method with which mild cognitive impairment (MCI) is detectable and a measurement reagent for use in the test method. A test method for MCI according to the present invention includes a step of measuring the activity of superoxide dismutase (SOD) in a biological sample of a subject.

The present disclosure provides compositions and methods for treating amyotrophic lateral sclerosis (ALS). Among other things, the present disclosure provides inhibitory nucleic acids that inhibit the expression of genes that cause or are implicated in ALS pathogenesis. The present disclosure further provides recombinant adeno-associated virus (rAAV) vectors comprising inhibitory nucleic acids that inhibit the expression of genes that cause or are implicated in ALS pathogenesis.

Animal feeds comprising probiotics are preserved using an enzymatic antioxidant. Polypeptides having catalase activity and/or superoxide dismutase activity preserve and promote probiotic growth and activity in animal.

The invention relates generally to the field of molecular biology and microbiology. Provided herein is an expression construct encoding a fusion protein. In one embodiment, there is provided an expression construct encoding a fusion protein, the expression construct comprising a nucleic acid encoding a first polypeptide for expression and a second polypeptide derived from the cell wall targeting region of a Lactobacillus plantarum Lys2 autolysin, wherein the first and second polypeptides are joined to form a fusion protein. In a specific embodiment, the second polypeptide comprises the CAD4a domain, which is a truncated domain containing only R1-R3 of the five-repeat SH3_5 domain of the Lys2 autolysin. Provided herein is also a fusion protein and the use of a fusion protein as defined herein.

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.
