In this study, the impact of lentil hull soluble dietary fibers (SDFs) on colitis and behavioral deficits in mice was assessed. Structural characterizations of SDFs confirmed that cellulase-modified soluble dietary fiber exhibited better physicochemical properties: more porous microstructure; similar polysaccharide structure; more stable particle size distribution; higher crystallinity; better adsorption capacity; and lower viscosity. Additionally, we explored its potential cognitive benefits via the gut-brain axis by behavioral tests, histopathology, 16S rRNA sequencing, gas chromatography and metabolomics analysis.

Quantum dot (QD) color conversion films (CCFs) hold significant promise for advancing display technologies with their superior color performance and efficiency. However, achieving long-term stability in QD-CCFs without additional air-barrier film coatings remains a challenge. Here, we develop a surface passivation strategy using zinc phenylbutyrate (Zn(PA)) to modify QDs through a trioctylphosphine-mediated surface reaction, which results in the selective capping of surface sulfur atoms by zinc-monophenylbutyrate.

This study evaluates the synergistic effects of silkworm feces and earthworms on nutrient-poor acidic red soils in Guangxi, China. Using 16S rDNA amplicon sequencing, soil samples from untreated fields, silkworm feces, earthworm gut contents, and soils treated with silkworm feces combined with three earthworm densities (50, 80, and 110 worms/kg) were compared. The earthworm gut microbiome increased in diversity in a density-dependent manner, while treated soils displayed enhanced microbial richness-with the 80 worms/kg treatment showing the highest diversity (605 genera).

Scalable fabrication of perovskite films with homogeneous structure remains a critical challenge in bridging power conversion efficiency gap between solar modules and laboratory-scale cells. To address this, we propose a slot-die coating strategy with pyrrodiazole additives in the perovskite precursor solution to simultaneously immobilize lead iodide and formamidinium iodide. This approach enhances wet film stability by suppressing colloidal aggregation, retards the crystal growth process, and ensures a consistent growth rate across the films.

Idiopathic pulmonary fibrosis (IPF) is a progressive lethal disease. Profibrotic fibroblast polarization during wound healing is one of the main causes of IPF, and the molecular mechanisms involved have yet to be fully determined. LIM domain-only protein 7 (LMO7), which acts as an E3 ubiquitin ligase, is highly expressed in the lung, brain and heart and plays important roles in embryonic development, cancer progression, inflammatory bowel disease and Dreifuss muscular dystrophy (EDMD).

In the field of non-silicon MEMSs (micro-electro-mechanical systems), nickel, with its mature preparation method, good compatibility with non-silicon MEMS processes, and excellent mechanical properties, is one of the commonly used structural materials. By effectively combining it with non-silicon MEMS processes, nickel is widely used in typical process systems such as LIGA (Lithography, Galvanoformung, Abformung)/UV-LIGA (Ultraviolet Lithography, Galvanoformung, Abformung). However, with the rapid development of the non-silicon MEMS field, pure nickel materials are no longer able to meet current material demands.

The tumor microenvironment (TME) plays a critical role in the poor clinical outlook for pancreatic ductal adenocarcinoma (PDAC). Activated pancreatic stellate cells (PSC) drive the complex interactions within the TME, resulting in a microenvironment that is resistant to chemotherapy and tolerant to the immune system, thereby promoting tumor growth. Effective deactivation of PSC is vital in treating pancreatic cancer.

Study Question: How frequently do infertility trials report live birth and pregnancy, and how consistently were their definitions reported?

Summary Answer: One-third of 1425 infertility trials published in the last decade reported live birth, with one in eight reporting clinical pregnancy, ongoing pregnancy, and live birth concurrently; absent, ambiguous, or heterogeneous definitions were common.

What Is Known Already: Absent or inconsistent outcome definitions in randomized controlled trials (RCTs) limit their interpretation and complicate subsequent evidence synthesis. While reporting live birth in infertility trials has been a long-running recommendation, the extent to which this is adhered to, and the temporal trend of adherence, is unclear.

Study Question: What are the trial characteristics, geographic distribution, and selected methodological issues of randomized controlled trials (RCTs) in infertility published from 2012 to 2023?

Summary Answer: Of the 1425 infertility RCTs, over two-thirds focused on IVF, nearly two-fifths did not use pregnancy or live birth as the primary outcome, a third lacked a primary outcome, a half were unregistered, and just over half were conducted in China (22%), Iran (20%), or Egypt (10%).

What Is Known Already: RCTs are the main source of evidence on the effectiveness of interventions. Knowledge about RCTs in infertility from the recent past will help to pinpoint research gaps and prioritize the future research agenda.

As an integral part of the innate immune system, the complement system is a tightly regulated proteolytic cascade, playing a critical role in microbial defense, inflammation activation, and dying host cell clearance. Complement proteins are now emerging as subjects of intense research and drug development, since dysregulation of the complement system plays a critical role in several diseases and disorders, such as paroxysmal nocturnal hemoglobinuria (PNH) and geographic atrophy (GA). Within the complement cascade, complement C3 is the central component, situated at the convergence of all complement activation pathways, rendering it an attractive target for complement-related diseases.
