La résistance aux benzimidazoles des nématodes gastro-intestinaux des petits ruminants en Gambie et au Sénégal

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1998
Cinquante-cinq troupeaux de petits ruminants en Gambie et au Sénégal ont été examinés en utilisant le test d'inhibition de l'éclosion des œufs et/ou le test de réduction des œufs de nématodes dans les fèces afin de détecter une résistance éventuelle aux

In Situ Synthesis of a Magnetic Graphene Platform for the Extraction of Benzimidazoles from Food Samples and Analysis by High-Performance Liquid Chromatography

Journal of Analytical Methods in Chemistry, 2017
A novel method was proposed for the determination of five benzimidazoles (oxfendazole, mebendazole, flubendazole, albendazole, and fenbendazole) using magnetic graphene (G-Fe3O4). G-Fe3O4 was synthesized via in situ chemical coprecipitation.

Excited State Modulation in Carbene‐Metal‐Amides to Design Fast and Bright Blue Delayed Fluorescence

Advanced Functional Materials, EarlyView.
Gold‐centered carbene‐metal amide (CMA) materials with carbonyl‐group substitution on the amide donor ligand. Molecular design ensures that the charge transfer (CT) state is lower in energy than the locally excited (3LE) states. The energy difference between CT and LE states controls the rate of the delayed fluorescence.

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

Advanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

In vitro anti-Leishmania activity of triclabendazole and its synergic effect with amphotericin B

Frontiers in Cellular and Infection Microbiology, 2023
IntroductionLeishmaniasis is a neglected tropical disease, with approximately 1 million new cases and 30,000 deaths reported every year worldwide. Given the lack of adequate medication for treating leishmaniasis, drug repositioning is essential to save ...

Metal‐Organic Frameworks Facilitating Complexation for Long‐Cycle Zinc‐Bromine Flow Batteries

Advanced Functional Materials, EarlyView.
The organic ligands (imidazole and benzimidazole) from the decomposed zinc ZIF‐62 is proposed to further improve the Br2 complexing ability of the mature complexing agent (i.e., N‐methyl‐N‐ethyl pyrrolidinium bromide (MEP) ionic liquid). The synergistic effect between Im/BIm of the decomposed ZIF‐62 toward bromine species and MEP toward bromine species,

Identification of novel pyrazole and benzimidazole based derivatives as PBP2a inhibitors: Design, synthesis, and biological evaluation

Archives of Pharmaceutical Sciences Ain Shams University, 2019
The antibiotic resistance of methicillin-resistant Staphylococcus aureus (MRSA) is attributable to the expression of the high molecular mass transpeptidase enzyme, penicillin-binding protein 2a (PBP2a), an enzyme that catalyzes the cross-linking reaction

Proton‐conducting polymers based on benzimidazoles and sulfonated benzimidazoles

Journal of Polymer Science Part A: Polymer Chemistry, 2002
AbstractA sulfonated derivative of polybenzimidazole is reported, and its properties are analyzed in comparison with related polybenzimidazole proton‐conducting materials. Poly(2,5‐benzimidazole), poly(m‐phenylenebenzobisimidazole), and poly[m‐(5‐sulfo)‐phenylenebenzobisimidazole] were prepared by condensation of the corresponding monomers in ...
