This study introduces the development of a highly sensitive label-free electrochemical immunosensor specifically designed to detect prostate-specific antigen (PSA). A glassy carbon electrode (GCE) coated with Au nanoparticles/polyhedral hollow CoCu bimetallic sulfide (CuCoS) was employed as a sensing interface for the fixation of the monoclonal anti-PSA antibody. The nanoarchitectures enhanced the capacity for loading prostate-specific antibodies (Ab) and effectually boosted electrical conductivity leading to enhance the electrochemical signal and greater sensitivity for the detection of PSA.

Usher syndrome is a rare autosomal recessive genetic disorder that primarily affects both vision and hearing, manifesting as sensorineural hearing loss and progressive vision loss caused by retinitis pigmentosa. The pathogenesis of retinal degeneration in Usher syndrome is still largely unknown. In this study, a novel Ush2a knockout mouse model was successfully constructed using CRISPR/Cas9 technology.

The existence of transmissible amyloid fibril strains has long intrigued the scientific community. The strain theory originates from prion disorders, but here, we provide evidence of strains in systemic amyloidosis. Human AA amyloidosis manifests as two distinct clinical phenotypes called common AA and vascular AA.

Late-onset Pompe disease (LOPD) includes patients from 1 year of age to adulthood. The vast heterogeneity in clinical manifestations and disease progression is not fully explained; however, a short disease duration and a young age seem to be good predictors of a better response to treatment. For this purpose, we investigated and followed up a cohort of 13 juvenile patients with LOPD from the clinical and therapeutic point of view, mainly pointing out the transition from presymptomatic to symptomatic status.

Our recent work revealed that a phenotype of dilation of the endoplasmic reticulum (ER), most notable for the perinuclear space (PNS), contributes to spongiform degeneration. To assess the significance of this phenotype for the etiology of prion diseases, we explored whether it can be functionally linked to other neuropathological hallmarks observed in these diseases, as this would indicate it to be a central event.
