Herein, a fluoroalkyl side chain modified A-DA'D-A small molecule acceptor, Y18-F9, was developed to optimize the bulk heterojunction morphology in organic solar cells. The introduction of fluorocarbon chains promotes self-assembly into nanoscale fibrous networks, while the low surface energy drive favorable vertical phase segregation. These synergistic effects lead to enhanced molecular packing, improved charge transport and collection, and reduced recombination losses.

This study aimed to investigate the effects of baicalin and citric acid on egg production performance, egg quality, and the intestinal morphology and function of laying hens. A total of 600 Hy-Line Brown laying hens, 59 weeks old, were randomly allocated to four dietary treatments, with 10 replicates per treatment and 15 hens per replicate. The control group was fed a basal diet, while the other three groups were fed the basal diet supplemented with 150 mg/kg baicalin (B), 2000 mg/kg citric acid (CA), or 150 mg/kg baicalin plus 2000 mg/kg citric acid (B + CA), respectively.

Background: The legacy of plant growth significantly impacts the health of subsequent plants, yet the mechanisms by which soil legacies in crop rotation systems influence disease resistance through rhizosphere plant-microbiome interactions remain unclear. Using a buckwheat-cabbage rotation model, we investigated how microbial soil legacies shape cabbage growth and clubroot disease resistance.

Results: Three-year field trials revealed that buckwheat rotation sustainably reduced clubroot severity by 67%-97%, regardless of pathogen load.

Continuous low-level exposure to pesticides is inevitable in daily life. Previous studies have demonstrated the adverse effects of pesticide exposure on lipid metabolism. However, population studies have focused primarily on individual pesticides and have short-term fluctuations, and the animal experiments used doses far higher than those exposed by the general population.

Background A newly recognized condition, the cardiovascular-kidney-metabolic (CKM) syndrome,integrated disease spectrum encompassing interlinked renal, cardiovascular, and metabolic dysfunction. Visceral adiposity plays a pivotal role in driving this multisystem deterioration. Although surrogate markers such as the visceral adiposity index (VAI), metabolic score for visceral fat (METS-VF), body roundness index (BRI), and weight-adjusted waist index (WWI) have been proposed to estimate visceral fat burden, their relationship with advanced CKM syndrome remains poorly defined.

Background: China has yet to implement a nationwide two-dose vaccination strategy. This study assesses the real-world effectiveness of varicella vaccination in Guangzhou, where the policy recommends voluntary, self-funded administration of two doses of the live attenuated vaccine, to provide insights for optimizing vaccination strategies.

Research Design And Methods: Using outbreak data from 2017 to 2022 across preschools, primary, and secondary schools, we employed a three-level matched case-control design (school, grade, and class) and applied conditional logistic regression to estimate the effectiveness of single-dose (VE1) and two-dose (VE2) vaccinations, incremental VE, and the effectiveness of emergency vaccination.

In the pursuit of advancing the commercialization of organic solar cells (OSCs), stability emerges as a paramount challenge. Herein, we show that the electron transport connectivity is a key factor determining the electron transport and device stability of OSCs. When compared to small molecular acceptors (SMAs), the larger-size polymeric acceptors (PAs) are likely to establish an electron transport network with superior connectivity.

The clinical success of covalent KRAS inhibition prompts further expansion of the concept to target non-cysteine oncogenic mutation sites as in KRAS. This endeavor was hampered by the lack of suitable electrophiles for the selective, covalent engagement of aspartate. Thanks to the recent discovery of β-lactone-bearing covalent inhibitors, new opportunities are emerging.

Lipophagy, a selective autophagy pathway targeting LDs, has emerged as a crucial regulator of immune cell function and immune response modulation. By degrading LDs, lipophagy provides essential energy to immune cells, supporting them during inflammation, infection, and cellular stress, and thus maintaining cellular homeostasis. Recent studies reveal lipophagy's influence on immune cell activation, cytokine secretion, antigen presentation, and cellular differentiation, demonstrating its importance in various diseases, including atherosclerosis, liver and kidney diseases, neurological disorders, and obesity-related metabolic conditions.

Introduction: Seasonal drought associated with the subtropical monsoon climate significantly impairs the growth and development of Camellia oil tree seedlings. While previous studies have established that drought stress elevates glutamate content in the rhizosphere of Camellia oil tree, the mechanisms through which glutamate modulates rhizosphere microbial community assembly remain unresolved.

Methods: To investigate the effects of glutamate on the rhizosphere environment under drought stress, we conducted an experiment using three-year-old potted seedlings subjected to moderate drought.

Inverted organic solar cells (OSCs) exhibit excellent stability, making them promising candidates for practical photovoltaic applications. However, the power conversion efficiency (PCE) of inverted devices still falls behind that of conventionally structured OSCs. In this work, a practical strategy for enhancing inverted device performance is demonstrated by introducing an organosilane-based passivation layer onto the ZnO transport layer via solution processing and thermal cross-linking.
