Clinical predictors of surgical intervention for gastrointestinal magnetic foreign bodies in children.

Background/aims: To investigate the clinical situation, treatment methods, and clinical predictors of surgical intervention in children with magnetic foreign bodies in the digestive tract.

Materials And Methods: From January 2019 to June 2022, we retrospectively analyzed the clinical data of 72 children who ingested magnetic foreign bodies inadvertently in our hospital, including their general information, admissions, clinical manifestations, and treatment methods, as well as pertinent literature and statistical data. Following software processing, univariate and multivariate logistic regression analyses were conducted to determine the independent risk factors of this study.

Manipulating the light-matter interactions in plasmonic nanocavities at 1 nm spatial resolution.

The light-matter interaction between plasmonic nanocavity and exciton at the sub-diffraction limit is a central research field in nanophotonics. Here, we demonstrated the vertical distribution of the light-matter interactions at ~1 nm spatial resolution by coupling A excitons of MoS and gap-mode plasmonic nanocavities. Moreover, we observed the significant photoluminescence (PL) enhancement factor reaching up to 2800 times, which is attributed to the Purcell effect and large local density of states in gap-mode plasmonic nanocavities.

CircRNA-ACAP2 contributes to the invasion, migration, and anti-apoptosis of neuroblastoma cells through targeting the miRNA-143-3p-hexokinase 2 axis.

Background: Circulating RNAs (Circ-RNAs) are tightly related to the processes of neuroblastoma. The circ-ACAP2 has been reported as dysregulated in various cancers; however, its biological roles and mechanisms in neuroblastoma remain largely unclear.

Methods: We collected 40 neuroblastoma tissues and adjacent noncancerous tissues.

Neonatal biliary atresia combined with preduodenal portal vein: A case report.

Background: Congenital biliary atresia is a type of obstruction of the bile ducts inside and outside the liver, which can lead to cholestatic liver cirrhosis and eventually liver failure. The preduodenal portal vein (PD-PV) is a rare developmental malformation of the PV. The PV courses in front of the duodenum.

A novel three-dimensional tumorsphere culture system for the efficient and low-cost enrichment of cancer stem cells with natural polymers.

Cancer stem cells (CSCs) are considered to serve a key role in tumor progression, recurrence and metastasis. Tumorsphere culture is the most important method for enriching CSCs and is widely used in basic research and drug screening. However, the traditional suspension cell culture system has several disadvantages, including low efficiency, high cost and difficult procedure, making it difficult to produce tumorspheres on a large scale.

Design of novel N-phenylnicotinamides as selective cyclooxygenase-1 inhibitors.

A series of N-phenylnicotinamides (1-40) were designed and evaluated in vitro for their COX inhibitory activities. Most of the synthesized compounds were proved to be potent and selective inhibitors of COX-1. Compound 28 showed the most potent COX-1 inhibitory activity (COX-1 IC(50) = 0.

Design, synthesis and biological evaluation of quinoline amide derivatives as novel VEGFR-2 inhibitors.

Vascular endothelial growth factor receptor-2 (VEGFR-2) plays a crucial role in the process of cancer angiogenesis. A series of quinoline amide derivatives were prepared and found to be good inhibitors of VEGFR-2. The inhibitory activities were investigated against VEGFR-2 kinase and human umbilical vein endothelial cells (HUVEC) in vitro.

Synthesis and antiproliferative activities against Hep-G2 of salicylanide derivatives: potent inhibitors of the epidermal growth factor receptor (EGFR) tyrosine kinase.

A series of salicylanilide derivatives (compounds 1-32) were synthesised by reacting substituted salicylic acids and anilines. The chemical structures of these compounds were determined by (1)H-NMR, electrospray ionisation mass spectrometry (ESI-MS) and elemental analysis. The compounds were assayed for their antiproliferative activities against the Hep-G2 cell line by the 3-(4,5-dimethylthylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method.

Design and synthesis of potent inhibitors of beta-ketoacyl-acyl carrier protein synthase III (FabH) as potential antibacterial agents.

Twenty new Schiff bases were synthesized by reacting 5-fluoro-salicylaldehyde and primary amine as potent inhibitors of FabH. These compounds were assayed for antibacterial activity against Escherichia coli, Pseudomonas fluorescence, Bacillus subtilis and Staphylococcus aureus. Compounds with potent antibacterial activities were tested for their E.

Design of novel nicotinamides as potent and selective monoamine oxidase a inhibitors.

A series of N-(2-morpholinoethyl)nicotinamide (1-13) and N-(3-morpholinopropyl)nicotinamide derivatives (14-26) have been designed, synthesized and evaluated in vitro for their monoamine oxidase (MAO) A and B inhibitory activity and selectivity. Most of these synthesized compounds proved to be potent, and selective inhibitors of MAO-A rather than of MAO-B. 5-Chloro-6-hydroxy-N-(2-morpholinoethyl)nicotinamide (13) displayed the highest MAO-A inhibitory potency (IC(50)=0.
