Blood-derived APLP1 extracellular vesicles are potential biomarkers for the early diagnosis of brain diseases.

The early detection of neurodegenerative diseases necessitates the identification of specific brain-derived biomolecules in peripheral blood. In this context, our investigation delineates the role of amyloid precursor-like protein 1 (APLP1)-a protein predominantly localized in oligodendrocytes and neurons-as a previously unidentified biomarker in extracellular vesicles (EVs). Through rigorous analysis, APLP1 EVs from human sera were unequivocally determined to be of cerebral origin.

Performance of Risk-Stratification Scores for Patients With Pulmonary Arterial Hypertension in a Multi-Ethnic Asian Population.

Guidelines recommend risk stratification of pulmonary arterial hypertension (PAH) patients to guide management. There are currently several risk stratification scores available, which have largely been validated in various pulmonary hypertension registries in the West but not in Asia. We aim to study the performance of these different risk scores in PAH patients from a multi-ethnic Asian population.

Caregiver Willingness to Participate in Pediatric Clinical Research During COVID-19.

Introduction: Understanding caregiver willingness to participate in pediatric clinical research is needed. We examined caregiver perceptions of pediatric clinical research during COVID-19 and examined research attitudes and sociodemographic factors as predictors of willingness.

Methods: A cross-sectional telephone survey was administered to caregivers of children from August 2020 to April 2021.

Enhancing glioblastoma therapy via intranasal administration of highly potent cell-penetrating peptide decorated nanoparticles.

Glioblastoma multiforme (GBM) is a devastating primary tumor of the central nervous system with a significantly poor prognosis. The primary challenge in treating GBM lies in the restrictive nature of the blood-brain barrier (BBB), impeding effective drug delivery to the brain. In this study, intranasal polymeric micelles encapsulating a quercetin-etoposide combination were developed to induce synergistic apoptotic effects and enhance direct drug delivery to the brain.

Generalized Langevin equation for a tagged monomer in a Gaussian semiflexible polymer.

In this study, we present a comprehensive analysis of the motion of a tagged monomer within a Gaussian semiflexible polymer model. We carefully derived the generalized Langevin equation (GLE) that governs the motion of a tagged central monomer. This derivation involves integrating out all the other degrees of freedom within the polymer chain, thereby yielding an effective description of the viscoelastic motion of the tagged monomer.
