A precipitation process of the calcium phosphates from precursors on a biopolymeric matrix based on chitosan, collagen, sodium hyaluronate, containing magnetic nanoparticles has been used to achieve porous magnetic scaffolds for bone tissue engineering. Porosity is one of the most important properties of a scaffold manufactured for applications in bone tissue engineering and regeneration and has been...
Pituitary adenylate cyclase activating polypeptide (PACAP), a neuropeptide with diverse effects, was originally isolated as a hypothalamo-hypophyseal peptide. Subsequent studies showed highest levels of PACAP in the testis after the brain, suggesting that it influences the development and functioning of spermatozoa. Indeed, it has been proven that PACAP has an effect on spermatogenesis, both locally...
