Achieving high open-circuit voltage (V) continues to pose a significant challenge for kesterite CuZnSn(S,Se) (CZTSSe) solar cells, predominantly due to the pronounced charge carrier recombination occurring at heterointerface (HEI). To address this issue, an innovative non-metallic boron (B)-modification strategy is developed to optimize the HEI. The key advantages of this strategy are as follows: (i) Leveraging the strong bonding characteristic of B with three valence electrons, the dangling bonds on the absorber surface can be fully saturated, effectively passivating surface states without introducing new defects; (ii) Moreover, diffusion of B into the near-surface region of HEI during selenization process can create weak n-type B donor defects, which lowers the valence band maximum (VBM) of the absorber and mitigates Fermi level pinning.

Dysregulated activation of the Wnt pathway is closely associated with oncogenesis and the progression of various cancers. Palmitoylation catalyzed by porcupine (PORCN) is essential for the secretion of Wnts and the activation of the Wnt pathway. Given its critical role in regulating Wnt signaling, PORCN has been recognized as a promising therapeutic target for cancers driven by aberrant Wnt pathway activation.

The p53 Y220C mutation is frequently observed in human cancers. This mutation renders the p53 Y220C unstable at physiological temperatures, leading to a loss of its normal function and promoting tumor development. In this study, a total of eight compounds were designed and synthesized based on the active compound C8.

The p53 Y220C mutation, a prevalent structural variant in human cancers, compromises DNA binding and tumor suppressor functions by destabilizing the protein structure. Leveraging a combined approach of structure-based virtual screening, molecular dynamics simulations, and in vitro assays, we have identified C8, a racemic compound with an indole core and α, β-unsaturated carbonyl groups, as a covalent stabilizer for p53 Y220C. Protein thermal shift and homogeneous time-resolved fluorescence assays confirmed that C8 and its analogs selectively bind to p53 Y220C and restore its DNA binding ability.

Our study aimed to investigate preferences for public health insurance coverage of new anticancer drugs among non-small cell lung cancer (NSCLC) patients in China.
Methods: We identified six attributes of new anticancer drugs and adopted a Bayesian-efficient design to generate choice scenarios for a discrete choice experiment (DCE).
Ginkgo biloba extract is reported to have therapeutic effects on aging-related disorders. However, the specific component responsible for this biological function and its mechanism of action remain largely unknown. This study finds that Ginkgetin, an active ingredient of Ginkgo biloba extract, can alleviate cellular senescence and improve pathologies in multiple tissues of aging mice.

CCK8 assays showed no cytotoxicity and good cell proliferation. The anti-inflammatory experiments demonstrated strong inhibition of NO release, transcriptional downregulation of classical effective cellular factors tumour necrosis factor-α, interleukin-6, interleukin-1β, and transcriptional upregulation of interleukin-10 in LPS-induced RAW264.

Kinase-targeted inhibitors hold promise for new therapeutic options, with multi-target inhibitors offering the potential for broader efficacy while minimizing polypharmacology risks. However, comprehensive experimental profiling of kinome-wide activity is expensive, and existing computational approaches often lack scalability or accuracy for understudied kinases. We introduce KinomeMETA, an artificial intelligence (AI)-powered web platform that significantly expands the predictive range with scalability for predicting the polypharmacological effects of small molecules across the kinome.

Objectives: Our study aimed to assess patient information needs for new antidiabetic medications using the best-worst scaling (BWS) experiment.
Objectives: Despite the advancement in anticancer drug therapies, cancer treatment decisions are often complex and preference-sensitive, making them well suited for studying shared decision-making (SDM). Our study aimed to assess preferences for new anticancer drugs among three common types of patients with cancer to inform SDM.
Design: We identified five attributes of new anticancer drugs and used a Bayesian-efficient design to generate choice sets for a best-worst discrete choice experiment (BWDCE).
Background: Diabetes is a major public health concern with a considerable impact on healthcare expenditures. Deciding on health insurance coverage for new drugs that meet patient needs is a challenge facing policymakers. Our study aimed to assess patients' preferences for public health insurance coverage of new anti-diabetic drugs in China.

The natural flavonoids luteolin and luteoloside have anti-bacterial, anti-inflammatory, anti-oxidant, anti-tumour, hypolipidemic, cholesterol lowering and neuroprotective effects, but their poor water solubility limits their application in industrial production and the pharmaceutical industry. In this study, luteolin-7-O-β-(6″-O-succinyl)-d-glucoside, a new compound that was prepared by succinyl glycosylation of luteolin by the organic solvent tolerant bacterium Bacillus amyloliquefaciens FJ18 in an 8.0% DMSO (v/v) system, was obtained and identified.
