Action observation treatment may improve daily living activities and verb recovery in Parkinson's disease-dementia: findings from a preliminary randomized controlled trial.

Background And Objectives: Action observation treatment (AOT) is a novel rehabilitation approach aimed to the recovery of both motor and linguistic deficits in subjects with brain lesions. The aim of the present randomized controlled study was to assess the benefits of AOT treatment in the activities of daily living (ADLs) and in the linguistic abilities of the patients with Parkinson's disease dementia (PDD) at mild-moderate stage (Hoehn & Yahr's stage scale: 2-3).

Methods: Twenty patients were enrolled and randomly assigned to an experimental group (submitted to AOT) or to a control group.

USP14 inhibition enhances Parkin-independent mitophagy in iNeurons.

Loss of proteostasis is well documented during physiological aging and depends on the progressive decline in the activity of two major degradative mechanisms: the ubiquitin-proteasome system (UPS) and the autophagy-lysosomal pathway. This decline in proteostasis is exacerbated in age-associated neurodegenerative diseases, such as Parkinson's Disease (PD). In PD, patients develop an accumulation of aggregated proteins and dysfunctional mitochondria, which leads to ROS production, neuroinflammation and neurodegeneration.

PD is a complex, multifactorial neurodegenerative disease, which occurs sporadically in aged population, with some genetically linked cases. Patients develop a very obvious locomotor phenotype, with symptoms such as bradykinesia, resting tremor, muscular rigidity, and postural instability. At the cellular level, PD pathology is characterized by the presence of intracytoplasmic neurotoxic aggregates of misfolded proteins and dysfunctional organelles, resulting from failure in mechanisms of proteostasis.

LaSrCaTiO Surface Reactivity with H: A Combined NEXAFS and Computational Study.

A-site doped SrTiO is considered as a promising substitute for traditional anodic metals in solid oxide fuel cells (SOFCs). In this study, we present the reactivity of LaSrCaTiO (LCSTO), LaSrTiO (LSTO), and SrTiO (STO) toward H by ambient pressure NEXAFS spectroscopy and theoretical spectra simulation with FDMNES code. The samples were synthesized by MBE (molecular beam epitaxy), hydrothermal, and modified-Pechini routes.
