Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

Photochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

PIII/PV Redox Organocatalysis Enables Intramolecular Aza‐Wittig Cyclizations of Imides: Direct Access to Pharmaceutically Relevant Amidine Scaffolds

Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
A metal‐free PIII/PV redox organocatalytic aza‐Wittig reaction enables the efficient cyclization of azide‐functionalized imides into pharmaceutically relevant amidine‐containing heterocycles. Using only 2 mol% of a methanophosphocine catalyst and a Brønsted acid additive, a broad range of substrates is converted in up to 96% yield, including ...

Scientific Opinion on waiving of the dog studies in the regulatory process of agrochemicals approval

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Commission Regulation (EU) No. 283/2013 sets out the data requirements for pesticide active substances and includes short‐term oral toxicity testing in rodents (90‐day rat study) and non‐rodents (90‐day dog study) to support human health hazard assessment for pesticide active substances in the European Union (EU). However, the relevance of the

Activity of Antioxidant Enzymes in Euphorbia heterophylla Biotypes and their Relation to Cross Resistance to ALS and Protox Inhibitors [PDF]

Planta Daninha, 2018
: The characteristics of multiple resistance in Euphorbia heterophylla biotypes to herbicides that are inhibitors of ALS (Acetolactate synthase) and PPO (Protoporphyrinogen oxidase) and their responsible mechanisms are still not completely elucidated ...

Performance of an S‐metolachlor capsule suspension for barnyardgrass control and crop tolerance in fenclorim‐treated rice

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Barnyardgrass [Echinochloa crus‐galli (L.) P. Beauv.] is the most problematic weed of delayed‐flooded rice (Oryza sativa L.) systems in the mid‐southern United States. Recent findings suggest that acetochlor can achieve effective barnyardgrass control in rice, but rice injury can occur with rainfall soon after application.

Glucose‐Modified Viscosity‐Responsive Turn‐On Fluorescence Molecular Rotors for Wash‐Free Live‐Cell Imaging

ChemBioChem, Volume 27, Issue 10, 27 May 2026.
We developed fluorescent molecular rotors (FMRs) that respond sensitively to intracellular viscosity. Based on the dye scaffold of GFP, we systematically investigated molecular rigidity and surface area, and discovered FMRs with remarkably high viscosity sensitivity.

Understanding the Opportunities to Mitigate Carryover of Imidazolinone Herbicides in Lowland Rice

Agriculture, 2021
(1) Background: The Clearfield™ system (CL) is currently the primary tool for selective weedy-rice management in irrigated rice. However, herbicide persistence in the soil may cause damage to successive crops.

Generation of imidazolinone herbicide resistant trait in Arabidopsis

PLOS ONE, 2020
Recently-emerged base editing technologies could create single base mutations at precise genomic positions without generation DNA double strand breaks. Herbicide resistant mutations have been successfully introduced to different plant species, including Arabidopsis, watermelon, wheat, potato and tomato via C to T (or G to A on the complementary strand)
