Q-switched lasers, for instance, emit short pulses of high-intensity light that fragment the melanin particles in the skin, allowing the body to gradually absorb and eliminate them
Its unique profile (native gastric peptide, stable without carriers, effective at nanogram doses, modulating multiple interconnected neurotransmitter systems simultaneously, promoting actual neuronal repair rather than just symptomatic relief) distinguishes it from all existing psychiatric medications
While united by a common mechanism, these agents vary significantly in their molecular structure, size, and half-lifeproperties that may influence their ability to penetrate the blood-retinal barrier (BRB) (Table 1)
Furthermore, a previous study showed that as a close structural analogue of L -tyrosine, L -DOPA can be incorporated into synthesized proteins, leading to protein misfolding and inactivation in SH-SY5Y neuroblastoma cells [117]
