DOI: 10.1007/s13311-019-00830-4
Abstract: The brainstem-based pedunculopontine nucleus (PPN) traditionally associates with motor function, but undergoes extensive degeneration during Parkinson’s disease (PD), which correlates with axial motor deficits. PPN-deep brain stimulation (DBS) can alleviate certain symptoms, but its mechanism(s)… read more here.

DOI: 10.1016/j.chemosphere.2018.12.163
Abstract: To provide superior substrates and determine the specific species of immobilized nano zero-valent iron (NZVI) system, polyacrylonitrile (PAN) membrane was functionalized by bio-inspired polydopamine (PDA) and poly(l-DOPA) (PDOPA) for efficient immobilization of NZVI. The synthesized… read more here.

DOI: 10.1016/j.neulet.2021.136308
Abstract: INTRODUCTION The connections of the pedunculopontine nucleus (PPN) with motor areas of the central nervous system (CNS) are well described in the literature, in contrast relations with non-motor areas are lacking. Thus, the aim of… read more here.
