Is self-perception related to speech perceptual analysis measures in early- and late-onset Parkinson’s disease? [PDF]

Dementia & Neuropsychologia
. Dysarthria is prevalent in Parkinson’s disease (PD) and has negative effects on communication and social interaction. A gap exists in understanding whether patient-reported outcome measures can effectively identify speech disorders prematurely ...

Conformation-driven reversibility control in ring-opening metathesis polymerization of non-bicyclic cyclooctenes [PDF]

Nature Communications
Reversible ring-opening metathesis polymerization (ROMP) of cyclooctene (COE) derivatives remains a challenge due to their high ring strain energies (RSEs).

Facial expression analysis to uncover the relationship between sialorrhea and hypomimia in Parkinson’s disease [PDF]

Frontiers in Neurology
Sialorrhea, or excessive drooling, is a prevalent yet frequently under-recognized non-motor symptom of Parkinson’s disease (PD). Hypomimia, or reduced facial expressivity, constitutes another significant feature of PD.

Effect of different catalyst ratios on the ring-opening metathesis polymerization (ROMP) of dicyclopentadiene [PDF]

Polyolefins Journal, 2022
In this paper, the polymerization process of polydicyclopentadiene (PDCPD) obtained by using dicyclopentadiene (DCPD) and the 2nd generation Grubbs’ catalyst is optimized. The curing reaction kinetics was studied by differential scanning calorimetry (DSC)
