Barriers and Facilitators to the Participation of Pregnant Women in Clinical Research: A Mixed-Methods Systematic Review.

Objectives: Pregnant women had a large demand for diagnosis and treatment, but the clinical research was not sufficient, and there were many barriers for pregnant women to participate in clinical research. This study aimed to systematically identify these barriers and facilitators, map them with Theoretical Domains Framework (TDF) and Behavior Change Techniques (BCTs) to inform the development of interventions promoting pregnant women's involvement in clinical research.

Methods: This was a mixed-methods systematic review.

[Influencing Mechanism of Precipitation Pollution Intensity in Qinhuai River Basin Based on Random Forest].

Analyzing the distribution characteristics of precipitation pollution intensity in the basin and identifying the main factors affecting the precipitation pollution intensity are the important basis for realizing the accurate management of diffused pollution. Based on the surface water quality data from four typical sections of the main stream of Qinhuai River Basin and rainfall data collected from 2021 to 2022, the distribution characteristics of precipitation pollution intensity in the basin were analyzed, and representative natural and social factors were selected to construct models of the precipitation pollution intensity of ammonia nitrogen （NH-N）, permanganate index, and total phosphorus （TP） based on random forest algorithm. Additionally, the main driving factors of precipitation pollution intensity were identified, and the influencing mechanism was analyzed.

[Analysis of root development of maxillary inverted impacted central incisor before and after orthodontic traction by CBCT].

Purpose: To investigate the changes of root development before and after orthodontic traction of maxillary inverted impacted central incisors using CBCT and Mimics software.

Methods: Ten patients, who had a maxillary inverted impacted central incisor, were treated using a modified movable retractor combined with surgical eruption. Cone-beam computed tomography(CBCT) was taken before and after treatment.

Enrichment of a heterotrophic nitrifying and aerobic denitrifying bacterial consortium: Microbial community succession and nitrogen removal characteristics and mechanisms.

This study cultivated a bacterial consortium (S60) from landfill leachate that exhibited effective heterotrophic nitrification and aerobic denitrification (HN-AD) properties. Under aerobic conditions, the removal of NH-N reached 100 % when the S60 consortium utilised NH-N either as the sole nitrogen source or in combination with NO-N and NO-N. Optimal HN-AD performance was achieved with sodium acetate as a carbon source and a pH of 7.

Enantioselective Synthesis of Isoindolinone by Sequential Palladium-Catalyzed Aza-Heck/Suzuki Coupling Reaction.

We present a tandem aza-Heck/Suzuki cross-coupling reaction of -phenyl hydroxamic ethers with readily available arylboronic and alkenyl boronic acids. This protocol is enabled by a palladium catalyst paired with chiral phosphoramidite ligands, particularly under mild reaction conditions, yielding efficient and succinct synthetic routes to chiral isoindolinones with high enantioselectivity. Furthermore, this reaction exhibits excellent functional group compatibility and a rich diversity of subsequent transformations.
