Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC–HRMS and Metabolomics Approach

Journal of Applied Toxicology, EarlyView.
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

Interrater reliability in pediatric high‐resolution anorectal manometry recordings

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives High‐resolution anorectal manometry (HR‐ARM) is a diagnostic test assessing anorectal neuromuscular function in children with constipation and/or fecal incontinence. Interrater reliability of HR‐ARM in children has not been previously studied. The aim of this study was to assess the interrater reliability of pediatric HR‐ARM studies.

Evaluation of antifungal and antimycotoxigenic activity of selected natural antioxidants against Fusarium culmorum: in vitro and in planta assays

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fusarium culmorum causes Fusarium head blight (FHB) in cereals, leading to significant yield losses and contamination with type B trichothecene mycotoxins such as deoxynivalenol (DON) and its acetylated derivatives 3‐ADON and 15‐ADON.
