Poly(itaconic acid) (PIA) is a renewable, biobased, hydrophilic polymer of superabsorbent properties, with the potential to replace synthetic superabsorbent polymers in agricultural applications.

Synthetic peptides were microencapsulated into liposomes, cycled with a disulfide bond or modified with d-phenylglycine (d-phg) at the N-terminal, and their antihypertensive effects as orally ...
