“Low‐Positive” MOG‐IgG Cases Among Adults With a First Event Suggestive of Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine the prevalence and clinical characteristics of patients with “low‐positive” (LP) MOG‐IgG (titres 1:160–1:320) among adults with a first demyelinating event (FDE) suggestive of multiple sclerosis (MS). Methods From the Barcelona CIS inception cohort, we included adult patients with serum collected ≤ 6 months from the FDE.

Effect of COMT and UGT1A Variants on Clinical Response to Opicapone in Parkinson's Disease. [PDF]

Mov Disord Clin Pract
Abstract Background Parkinson's disease (PD) is the second most common neurodegenerative disease. Symptomatic treatment is based on dopaminergic replacement. With disease progression, the initial benefit of levodopa becomes inconsistent, and motor complications emerge.

From Bulk to Colloidal Nanocrystals: Top‐Down Synthesis of Highly Luminescent Cs2ZrCl6:Te4+ Double Perovskite Nanocrystals for X‐Ray Imaging

Advanced Functional Materials, EarlyView.
Top‐down ultrasonication produces highly emissive Cs2ZrCl6:Te4+ nanocrystals (NCs) with a PLQY of 65%, which is higher compared to that of the NCs synthesized by typical bottom‐up hot‐injection synthesis. The colloidal Cs2ZrCl6:Te4+ NCs have been found to be potential candidates for x‐ray scintillation imaging.

Hybridization of Gap Plasmons and Grating‐Coupled Surface Plasmon Polaritons in Metal Nanoparticle Cluster Arrays on a Mirror

Advanced Optical Materials, EarlyView.
Here we use a template‐assisted self‐assembly approach of metal colloids onto metal films to produce hybrid plasmonic metasurfaces that integrate nanoparticle‐on‐mirror cavities with periodic metal colloid arrays. The resulting coupling between gap plasmons and grating‐coupled surface plasmon polaritons enables programmable hybrid modes with tailored ...

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Pyridinium Cations Act as Charge Reservoirs in Expanded Halide Perovskite Analogs at High Pressure

Angewandte Chemie, EarlyView.
Redox‐innocent pyridinium derivatives can act as charge reservoirs in expanded tin‐iodide perovskite analogs. Material compression reduces the energy gap between the pyridinium π* acceptor orbital and the valence‐band maximum, facilitating electron transfer from the framework to the molecules and thereby significantly increasing electronic conductivity
