Incidence and Risk Factors for Nonreversal of Stoma in Patients With Crohn's Disease: A Single-Center Study.

Background: Even in the biological era, permanent stoma is not uncommon in patients with Crohn's Disease.

Objective: This study aimed to investigate the incidence and risk factors of permanent stoma in Crohn's disease patients and provide clinical evidence for reducing this disabling outcome.

Design: Consecutive patients with Crohn's disease who underwent ostomies in the past decade were reviewed.

Engineering ZIF-8@Ag core-satellite superstructures through solvent-induced tunable self-assembly for surface-enhanced Raman spectroscopy.

Metal-organic framework (MOF) based substrates have great potential for quantitative analysis of hazardous substances using surface-enhanced Raman spectroscopy (SERS) due to their significant signal enhancement, but face challenges like complex preparation, and lack of tunability. Here, we have successfully prepared a well-defined core-satellite superstructure (ZIF-8@Ag) through solvent-induced assembly of silver nanoparticles (Ag NPs) on truncated rhombic dodecahedral ZIF-8. By wisely selecting toluene as the solvent, the assembly process can be easily initiated through ultrasonic treatment and it allows for precise morphological adjustments to build a range of superstructures with different assembly densities of Ag NPs feed ratio tuning.

Boron's Role in Diminishing Cadmium Concentrations in Rice ( ): Insights into Absorption Inhibition and Ripening Promotion.

Boron, a crucial element for plant growth, has been demonstrated to mitigate cadmium (Cd) absorption in rice seedlings. However, its impact on Cd accumulation in rice grains and the underlying regulatory mechanisms remain poorly understood. The current study explored the roles of boron in reducing Cd accumulation and promoting ripening in rice through pot and hydroponic experiments.

Harnessing Hole Sites in 2D Monolayer C for Metal Cluster Anchoring.

Synthesis of 2D quasi-hexagonal phase C (qHP C) has opened avenues for its application as a novel catalytic support. This study investigates the structure, stability, and anisotropic properties of Cu clusters anchored on the qHP C surface through density functional theory calculations. Our findings reveal that the Cu cluster preferentially occupies the intrinsic holes of the qHP C via one of its tetrahedral faces, resulting in enhanced stability and conductivity, with a significantly reduced band gap of 0.

Superhydrophobic Surface-Enhanced Raman Spectroscopy (SERS) Substrates for Sensitive Detection of Trace Nanoplastics in Water.

Nanoplastics, emerging as pervasive environmental pollutants, pose significant threats to ecosystems and human health due to their small size and potential toxicity. However, detecting trace levels of nanoplastics remains challenging because of limitations in the current analytical methods. Herein, we propose a method that combines superhydrophobic enrichment with SERS analysis for detecting trace nanoplastics in aqueous environments.
