The Relationship Between Enlarged Perivascular Spaces and Cognitive Function: A Meta-Analysis of Observational Studies.

Enlarged perivascular spaces (ePVS), visible on magnetic resonance imaging (MRI), are associated with aortic pulse wave changes produced by arterial stiffening. However, the relationship between ePVS and cognition is still unclear. We aimed to benchmark current knowledge of associations between ePVS and cognitive function using a meta-analysis of all available published data.

Preparation, Characterization and Application of UV-Curable Flexible Hyperbranched Polyurethane Acrylate.

A novel UV-curable hyperbranched polyurethane acrylate (FHBPUA) with excellent flexibility is successfully synthesized based on a reaction of hydroxyl terminated hyperbranched polyurethane (regarded as core) with flexible semiadduct urethane monoacrylate (regarded as arms). The structure and property of FHBPUA is firstly analyzed and then utilized as functional additives to ameliorate the UV-curing and mechanical properties of epoxy acrylate resin. The degree of branching of FHBPUA turns out to be 0.

Exploring MicroRNAs on NIX-Dependent Mitophagy.

The dysregulation of autophagy is implicated in many pathological disorders including infections, aging, neurodegenerative diseases, and cancer. Autophagy can be precisely controlled both transcriptionally and translationally. Accumulating evidences show that the autophagy response is regulated by microRNAs, which therefore becomes subject area of interest in recent years.
