Blind nasoenteric tube placement risks: A case report of misplacement into the pleural cavity.

Rationale: Enteral nutrition is a critical component of care for critically ill patients. However, the blind insertion of a nasoenteric tube, despite being a simple procedure, carries inherent risks that necessitate a reevaluation of the technique.

Patient Concerns: A case of a 60-year-old female experienced the rare yet critical complication of a misplaced nasoenteric tube entering the thoracic cavity during a blind insertion procedure for enteral nutrition following a liver transplant.

High grazing pressure accelerates changes in community assembly over time in a long-term grazing experiment in the desert steppe of northern China.

Although numerous studies have shown that grazing gives rise to community succession from the communities or even species perspective, there is a lack of discussion about how grazing drives community assembly based on plant functional traits in a long-term experiment. We find different grazing intensities lead to temporal effects on trait-mediated multidimensional community assembly processes, including community-weighted trait mean (CWM), trait filtering, and trait distribution (divergence/convergence). CWM, trait filtering, and trait distribution of different traits transformed over the 16-year grazing experiment.

Integrating L-Cys-AuNCs in ZIF-8 with Enhanced Fluorescence and Strengthened Stability for Sensitive Detection of Copper Ions.

Gold nanoclusters (AuNCs) have been widely investigated because of their unique photoluminescence properties. However, the applications of AuNCs are limited by their poor stability and relatively low fluorescence. In the present work, we developed nanocomposites (L-Cys-AuNCs@ZIF-8) with high fluorescence and stability, which were constructed by encapsulating the water-dispersible L-Cys-AuNCs into a ZIF-8 via Zn-triggered growth strategy without high temperature and pressure.

Integration of paper-based colorimetric microdevice and magnetic nanoparticles affinity for high-throughput capture of antimicrobial resistance-reversing agent from complex natural products.

Efficient analysis of active ingredient in complex natural products is crucial for drug discovery, but developing a simple method for this is challenging. The discovery of drugs against bacterial resistance is urgent because drug-resistant bacteria produce β-lactamases, which inactivate antibiotics and increase infection risks, particularly the AmpC β-lactamase. Here, an integrated analytical model based on colorimetric sensing and magnetic nanoparticles (MNPs) affinity chromatography was developed for screening AmpC β-lactamase inhibitors.

Nutrient loading accelerates breakdown of refractory dissolved organic carbon in seagrass ecosystem waters.

Nutrient loading is a major driver of seagrass ecosystem decline and also threatens the capacity for seagrass ecosystems to act as 'blue carbon' sinks. Dissolved organic carbon (DOC) represents a crucial component of carbon storage in seagrass ecosystems, with refractory DOC (RDOC) playing a key role in long-term (millennial time scale) carbon stocks. The processes governing RDOC are heavily influenced by microbial activity.

Casein-grape seed proanthocyanidins complexes stabilized Pickering emulsion gels based on Lycium Barbarum seed oil with excellent mechanical properties and oxidation resistance.

Pickering emulsion gels received extensive attention in encapsulating fat-soluble substances such as Lycium barbarum seed oil (LBSO).
