Motor Learning of Complex Tasks with Augmented Feedback: Modality-Dependent Effectiveness.

Background: This paper aims to evaluate the effectiveness of feedback modalities in the motor learning of complex tasks.

Methods: This study examined sixty-one male university students randomised to three groups: group Verbal (VER) = 20 (body height 178.6 ± 4.

Synthesis of new chiral peptide nucleic acid (PNA) monomers.

We have synthesised a series of new chiral type I peptide nucleic acid monomers in total yields of 36-53%, derived from Val, Ile, Ser(Bzl), Pro, and Trp, employing convenient procedure.

Synthesis and characterization of new chiral peptide nucleic acid (PNA) monomers.

PNAs are DNA analogues in which the nucleic acid's backbone is replaced by a chiral or achiral pseudopeptide backbone and nucleobases are attached to the backbone by methylene carbonyl linkers. The easy to modify PNA structure gives the possibility to obtain monomers, and subsequently oligomers, with improved properties. We have synthesised several new PNA monomers, starting from a series of 2'-substituted methyl N-(2-Boc-aminoethyl)glycinates.
