Construction and Comparison of Molecular Identification Methods for Mannheimia haemolytica

Mannheimia haemolytica is a primary pathogen causing bacterial pneumonia in cattle and sheep. Multiple PCR targets exist for its identification, but no standardized primer pairs have been widely adopted. This study evaluated the universality of six reported primers (including rpt...

Assessing the toxicological effects of synthetic musk ketone using the Caenorhabditis elegans model

Synthetic musk ketone (MK) is extensively used in perfumes, cosmetics, and detergents. Due to its high lipophilicity, persistence, and limited removal efficiency in wastewater treatment, MK has been detected in various environmental matrices and human tissues. However, the ecotox...

High-Performance NiCu Graphite-Felt Anode Based on in Situ Exfoliating Graphene for Direct Ammonia Fuel Cells

Abstract Direct ammonia fuel cell (DAFC) has broad prospects in the field of sustainable energy due to their advantages, including high energy density and zero carbon emissions. However, the slow kinetics of ammonia oxidation reaction (AOR) in low-cost non-noble metal anode, alon...

On the Periodic Cauchy Problem for the μ‐Modified Camassa‐Holm‐Novikov Type Equation

ABSTRACT This paper delves into the intricate periodic Cauchy problem associated with the ‐modified Camassa‐Holm‐Novikov equation. We first rigorously demonstrate that the occurrence of blow‐up phenomena in this equation is exclusively manifested through the formation of breaking...

MicroRNAs in HCC: regulatory roles and therapeutic potential

Hepatocellular carcinoma (HCC) ranks among the malignancies with the highest mortality rates worldwide. Owing to the lack of effective diagnostic and therapeutic strategies, patient prognosis generally remains poor. MicroRNAs (miRNAs) function as both oncogenes and tumor suppress...

An efficient photo-Favorskii rearrangement of α-chloroketones for the synthesis of 2-arylpropionic acids
