The present disclosure provides recombinant nucleic acids comprising one or more polynucleotides encoding one or more cosmetic proteins (e.g., one or more human collagen proteins); viruses comprising the recombinant nucleic acids; compositions (e.g., cosmetic formulations) comprising the recombinant nucleic acids and/or viruses; methods of their use; and articles of manufacture or kits thereof.

The present invention relates to the fields of medicine, cell biology, molecular biology and genetics. In particular, the present invention provides methods to isolate and purify microvesicles from cell culture supernatants and biological fluids. The present invention also provides pharmaceutical compositions of microvesicles to promote or enhance wound healing, stimulate tissue regeneration, remodel scarred tissue, modulate immune reactions, alter neoplastic cell growth and/or mobility, or alter normal cell growth and/or mobility. The present invention also provides compositions of microvesicles to be used as diagnostic reagents, and methods to prepare the compositions of microvesicles.

Apparatus and methods for separating blood components are disclosed in which an apparatus for separating blood generally includes a tube defining a channel and configured for receiving a quantity of blood and a float contained within the tube and having a density which is predefined so that the float is maintained at equilibrium between a first layer formed from a first fractional component of the blood and a second layer formed from a second fractional component of the blood. Upon completion of the centrifugation, the first layer may be removed from the tube while the float isolates the second layer from the first layer.

With supporting experimental data, this disclosure teaches that IF1 protein activity is a molecular determinant of lifespan, therein explaining why different species have different maximal lifespans, and it teaches a IF1 protein/fragment (or sequence variant thereof), or a fusion protein thereof, optionally a fusion protein comprising a Cell Penetrating Peptide (CPP) sequence, as an agent to slow/delay/reduce aging in a subject, optionally as a component of a cosmetic, optionally to treat an age-correlated disease/disorder. Moreover it teaches other inhibitors of F1F0 ATP hydrolysis, including small molecules, of a number of different scaffolds, for this purpose. Furthermore, with supporting experimental data, it teaches that compounds that slow the ATP-hydrolysing mode of ATP synthase are useful for treating various diseases and disorders, including cancer, particularly cancers that utilise the Warburg effect.
