A human platelet lysate preparation that contains human plasma is provided. This preparation can be generated from human platelets by concentrating and washing them under defined conditions to control the degree of human plasma present. The washed platelet concentrate is then subjected to a freeze-thaw cycle to produce platelet lysate which is centrifuged and filtered through 0.65μ, 0.45μ and 0.2μ filters, aliquoted and stored frozen at <−20° C. until thawed for use. This invention describes the novel finding that the controlled addition of human plasma to the lysate preparation significantly enhances the cell growth potency of the lysate preparation. This lysate can be used as a media supplement to replace fetal bovine serum (FBS) or other non-human serum additives used for the culture of mammalian cells. This invention also describes the formulation and use of the lysate preparation as a topical application for skin care, and wound healing, including anti-wrinkling, anti-scarring and wound resolution applications of the invention.

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.

The present invention relates, in part, to methods of preventing or treating macular degeneration in a subject by administering a composition comprising a superoxide dismutase enzyme. The present invention also provides pharmaceutical and/or food compositions comprising a superoxide dismutase enzyme.

Radioprotection, Radiomitigation and Radiorecovery: Timed use of more widely available antiradiation agents in a kit for subjects affected by ionizing radiation, radiomimetic exposure and radio contamination. The method in the form of strategically timed preemptive and post-irradiation compositions; radioprotection, radiomitigation and radiorecovery formulations are comprised of various available anticorporation, antioxidant, decorporation, multi-mechanistic, pro-survival, pro-hematopoietic, anti-fibrotic and other novel ingredients in synergistic mixtures to be used in critically-timed manners. Radioprotection, radiomitigation and radiorecovery of a mammal prior to, during, just after or well-after exposure to ionizing radiation energy—alpha, beta, neutron, gamma, X-ray and damaging radiofrequency radiation—for long or short periods of time, and exposure to or contamination by radioactive elements or compounds such as radioiodine, radiostrontium, radiophosphorus, radiocobalt, radiocadmium, radiopollonium, radioradium, radiocesium, radiouranium, radioamericium, radiopollonium, radiocerium, radioindium, and the like. Radiomimetic protective method for mucosal exposure is also described.

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.

The disclosure in some aspects, relates to nucleic acids, compositions and kits useful for gene therapy with reduced immune response to transgene products.

A composition comprising an endothelial progenitor cell genetically modified to have transiently reduced p53 expression for treating diabetic kidney disease and uses thereof

A micro-environment bioreaction aggregate (MEBA) is formed by combining a non-digestible carrier system with redox potential (E.sub.h) regulating compounds. The bioreaction aggregate is introduced into a microbial environment, such as soil, hydroponic systems, or gastrointestinal tracts of animals or humans. Said MEBA regulates the E.sub.h of the microbial microhabitat and its surroundings, thereby providing numerous benefits towards the prevention and treatment of diseases and dysbiosis.

The present invention is directed to methods for the treatment or prevention of oxidative stress in a cell, e.g., photoreceptor cell, and methods for the treatment and prevention of disorders associated therewith by the administration of an agent, e.g., a nucleic acid molecule, which increases the expression and/or activity of an antioxidant defense protein.

The present disclosure relates to methods of feeding animals by providing feed additives that modulate the gut microbiome to improve the health, nutrition, and growth performance. The present disclosure further relates to methods of modulating metabolites present in the gastrointestinal tract of an animal. Such modulation includes, for example, modulating the level said metabolites.
