A new aguanidine-based bis Schiff base for highly selective Al recognition, BSA binding studies and theoretical calculations.

Herin, the successful synthesis of a bis Schiff base (L) has been achieved using 2-hydroxy-1-naphthaldehyde and 1,3-diaminoguanidine as raw materials, which was further characterized by infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance hydrogen spectrum. Moreover, spectroscopic experiments demonstrated that the probe L showed good selectivity and visual detectability for Al. Its detection limit (DL) is 2.

Molecular characterization and antimicrobial susceptibility for 62 isolates of from children.

Background: Pertussis is a highly contagious respiratory disease caused by (BP). Despite global control of pertussis cases through the Expanded Programme on Immunization (EPI), there has been a significant increase in the incidence of pertussis in recent years, characterized by a "resurgence" in developed countries with high immunization rates as well as a comparable reemergence in certain areas of China. We aim to explore the genotypes and antimicrobial susceptibility of circulating BP from children in Hebei.

NEDD4L inhibits epithelial-mesenchymal transition in gastric cancer by mediating BICC1 ubiquitination.

Epithelial-mesenchymal transition (EMT) is a critical stage in the metastasis of gastric cancer (GC). Further clarification of the EMT process in GC is still needed. This study examined the effects of the NEDD4L/BICC1 axis on GC proliferation and the EMT process.

Surface-enhanced Raman spectroscopy: a half-century historical perspective.

Surface-enhanced Raman spectroscopy (SERS) has evolved significantly over fifty years into a powerful analytical technique. This review aims to achieve five main goals. (1) Providing a comprehensive history of SERS's discovery, its experimental and theoretical foundations, its connections to advances in nanoscience and plasmonics, and highlighting collective contributions of key pioneers.

Key site residues of Cnaphalocrocis medinalis odorant-binding protein 13 CmedOBP13 involved in interacting with rice plant volatiles.

Odorant binding proteins (OBPs) play key roles in the insect olfactory system by assisting the neuronal response to hydrophobic odor molecules, understanding their interaction with ligands will facilitate the virtual screening of behaviorally active compounds in insects. Here, we successfully cloned and confirmed CmedOBP13, an antennae-biased OBP from the rice leaffolder Cnaphalocrocis medinalis, as a secreted protein. Recombinant CmedOBP13 was obtained using the Escherichia coli system, and its binding affinities to 35 volatile compounds emitted by rice plants and three sex pheromone components from female moths were assessed by a competitive binding assay.
