Basic Science and Pathogenesis.

Background: Tau aggregation is the major cause of several neurodegenerative tauopathies. Tau interaction with other proteins affects the formation of tau aggregates with seeding activity but less is known about its effects on tau-seed properties. Our previous study revealed that Bassoon (BSN), a presynaptic protein, interacts with tau-seed, exacerbating its toxicity in vivo.

Longitudinal Metabolomics Reveals Metabolic Dysregulation Dynamics in Patients with Severe COVID-19.

A dysregulated metabolism has been studied as a key aspect of the COVID-19 pathophysiology, but its longitudinal progression in severe cases remains unclear. In this study, we aimed to investigate metabolic dysregulation over time in patients with severe COVID-19 requiring mechanical ventilation (MV). In this single-center, prospective, observational study, we obtained 236 serum samples from 118 adult patients on MV in an ICU.

Long-term prevalence of PTSD symptom in family members of severe COVID-19 patients: a serial follow-up study extending to 18 months after ICU discharge.

Background: Experiencing a loved one's stay in the intensive care unit (ICU) can profoundly affect families, often leading to post-intensive care syndrome-family (PICS-F), a condition particularly exacerbated during the COVID-19 pandemic. While PICS-F significantly impacts the mental health of families of ICU patients, especially in the context of COVID-19, the long-term effects beyond 12 months remain understudied. This study aims to explore the prevalence of PTSD-related symptoms and health-related quality of life (HRQOL) in family members up to 18 months after ICU discharge.

VE-cadherin may suppress inflammation depending on the phase of inflammation of rheumatoid arthritis.

Objectives A disintegrin and metalloproteinase (ADAM)-15 and vascular endothelial (VE)-cadherin are involved in angiogenesis. We investigated the relationship between ADAM-15 and VE-cadherin expressions in rheumatoid arthritis (RA). Methods VE-cadherin concentrations in the serum of patients with RA were measured using the enzyme linked immunosorbent assay (ELISA).
