ročník celostátní soutěže o nejlepší studentskou vědeckou práci Hybrid sol–gel inorganic–organic fibres offer great potential in tissue engineering and regenerative medicine. A significant challenge is to process them using scalable technologies into useful scaffolds that provide control over fibre diameter, morphology, mechanical properties, ion release, degradation and cell response. In this work we develop formulations that are amenable to The invention relates to mRNA therapy for the treatment of cystic fibrosis. mRNAs for use in the invention, when administered in vivo, encode cystic fibrosis transmembrane conductance regulator (CFTR), isoforms thereof, functional fragments thereof, and fusion proteins comprising CFTR. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery Retinal ganglion cells (RGCs) consume large quantities of energy to convert light information into a neuronal signal, which makes them highly susceptible to hypoxic injury.
