Narrative mobile video game-based cognitive training to enhance frontal function in patients with mild cognitive impairment.

Although cognitive training has been proposed as a possible therapeutic modality for mild cognitive impairment (MCI), most serious games focus on specific tasks. This study aimed to investigate the feasibility and efficacy of narrative video game-based cognitive intervention for MCI. A four-week (± 1-week) mobile game intervention was given to 17 MCI participants (mean age (SD) = 72.

Longitudinal Trajectory of Dopamine and Serotonin Transporters in Parkinson Disease.

Parkinson disease (PD) is a multisystem disorder marked by progressive dopaminergic neuronal degeneration in the substantia nigra, as well as nondopaminergic systems. Our aim was to investigate longitudinal changes in -(3-[F]fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane (F-FP-CIT) binding at the putamen, substantia nigra, and raphe nuclei in PD. This retrospective cohort study enrolled 127 patients with PD, who underwent F-FP-CIT PET scans twice or more, and 71 age- and sex-matched healthy controls.

Diagnostic criteria for temporomandibular joint osteoarthritis using standardized uptake value in single-photon emission computed tomography-computed tomography.

This study aimed to investigate the cutoff values of standardized uptake values (SUVs) and their accuracy using single-photon emission computed tomography-computed tomography (SPECT-CT) for temporomandibular joint (TMJ) osteoarthritis (OA) based on magnetic resonance imaging (MRI) and clinical examination. We included 106 joints of 53 patients with TMJ OA. SUVmax and SUVpeak of each TMJ was measured.

Transcriptomic comparison of corneal endothelial cells in young versus old corneas.

Corneal endothelial cells, situated on the innermost layer of the cornea, are vital for maintaining its clarity and thickness by regulating fluid. In this study, we investigated the differences in the transcriptome between young and old corneal endothelial cells using next-generation sequencing (NGS). Cultured endothelial cells from both young and elderly donors were subjected to NGS to unravel the transcriptomic landscape.

Hearing modulation affects Alzheimer's disease progression linked to brain inflammation: a study in mouse models.

Background: Recent studies have identified hearing loss (HL) as a primary risk factor for Alzheimer's disease (AD) onset. However, the mechanisms linking HL to AD are not fully understood. This study explored the effects of drug-induced hearing loss (DIHL) on the expression of proteins associated with AD progression in mouse models.
