Characterization of quorum quenching enzyme AiiA and its potential role in strawberry preservation.

Microbial spoilage in nutrient-rich strawberries has led to significant food waste and economic loss in the food industry. The quorum-quenching enzyme AiiA is believed to disrupt communication between cells by inactivating AHLs-based quorum sensing signals. Chitosan, a biopolymer derived from chitin, is widely used as a coating film to inhibit bacterial growth and prolong food shelf life.

First Determination of the Spin-Parity of Ξ_{c}(3055)^{+,0} Baryons.

The Ξ_{b}^{0(-)}→Ξ_{c}(3055)^{+(0)}(→D^{+(0)}Λ)π^{-} decay chains are observed, and the spin-parity of Ξ_{c}(3055)^{+(0)} baryons is determined for the first time. The measurement is performed using proton-proton collision data at a center-of-mass energy of sqrt[s]=13  TeV, corresponding to an integrated luminosity of 5.4  fb^{-1}, recorded by the LHCb experiment between 2016 and 2018.

Morphology Effect of FeWO Boosting Efficiency of Photocatalytic Uranium Extraction under Visible Light and Mechanism Investigation.

Wolframite (FeWO) is a type of polyoxometalate known for its high chemical stability and electronic properties, which makes it an excellent photocatalyst. While FeWO has been widely utilized in the domain of organic catalysis, there are currently no documented reports regarding its use in the degradation of U(VI). In this study, the effect of changing the microscopic morphology of the FeWO catalyst to enhance its photocatalytic activity was explored.

Diaphragm excursion difference as an adjunct predictor marker of postoperative pulmonary complications in video-assisted thoracoscopic surgery: a prospective, observational study.

Background: Video-assisted thoracoscopic surgery (VATS) often leads to a significant number of postoperative pulmonary complications (PPCs). The diaphragm is the primary muscle involved in respiration. Diaphragm ultrasound is increasingly used as a noninvasive and portable tool for evaluating diaphragmatic contractile function.

Mannose-modified erythrocyte membrane-coated Chuanmingshen violaceum polysaccharide PLGA nanoparticles to improve immune responses in mice.

This study developed a poly(lactic-co-glycolic acid) (PLGA) biomimetic nanoparticle (Man-RBC-CVPP) containing Chuanmingshen violaceum polysaccharide (CVP) and coated with a macrophage-targeting mannose receptor (DSPE-PEG-Man) modified RBCM. In vitro experiments demonstrated that Man-RBC-CVPP enhances antigen uptake and immune responses in RAW264.7 cells and can induce an immune response in mouse macrophages by activating the TLR4-mediated NF-κB signaling pathway.
