Early Versus Late Recurrence in Olfactory Neuroblastoma: A Multi‐Institutional Analysis of Predictive Risk Factors

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory neuroblastoma (ONB) exhibits variable recurrence patterns, with significant late recurrences occurring years after treatment. We investigated cutoff periods to define late recurrence and identified predictors that distinguish patients at risk of late recurrence from those considered cured.

A Wagner–Meerwein‐Like Rearrangement Generates a Vinyl Group in the Biosynthesis of the Polychlorinated Lipopeptides Fischerazoles

Angewandte Chemie, EarlyView.
The fischerazoles, unusual cyanobacterial chlorinated lipopeptides are reported. During their biosynthesis, a linear fatty acyl‐acyl carrier protein (ACP) precursor is rearranged through the action of the S‐adenosyl‐methionine (SAM)‐dependent methyltransferase FshF, to generate a pendant vinyl group.

Cell therapy comparison of dental pulp stem cells, hepatocytes, and their exosomes for liver fibrosis treatment in rats

Animal Models and Experimental Medicine, EarlyView.
DPSCs, hepatocytes, and exosomes were tested for liver fibrosis therapy. Exosome‐based treatment exhibited superior antioxidative and regenerative effects. Liver enzymes, oxidative stress, and profibrotic markers were significantly reduced. α‐SMA, desmin, and related gene expression were downregulated.

Assessing Progression Independent of Relapse Activity in Multiple Sclerosis Using a Patient‐Reported Disability Measure and Self‐Administered Neuroperformance Outcomes

Annals of Neurology, EarlyView.
Objective The objective of this study was to investigate the ability of patient‐reported/administered outcomes to capture disability worsening and progression independent of relapse activity (PIRA) in multiple sclerosis (MS). Methods We included patients from the longitudinal multicenter MS PATHS cohort with ≥3 assessments and >6 months follow‐up. PIRA

Mechanically Interlocked Indigo Photoswitches

Angewandte Chemie, EarlyView.
By incorporating indigo photoswitches into the axle of a rotaxane, which features a hydrogen bonding macrocycle, we demonstrate improvement in activation wavelength, photostationary states and thermal reversion, an effect that is governed by topologically constrained supramolecular interactions.

Ketazine‐Linked Covalent Organic Framework for Metal‐Free Electrocatalytic Nitrate‐to‐Ammonia Conversion

Angewandte Chemie, EarlyView.
A metal‐free fluorinated ketazine‐linked COF is introduced as an efficient electrocatalyst for nitrate reduction to ammonia under neutral conditions. Fluorine substitution enhances π–π stacking and crystallinity, enabling a Faradaic efficiency of 59.9% and an NH3 yield rate of 1639.9 µmol h−1 mgCOF−1 at −0.9 V versus RHE. This establishes an unexplored
