ethanolic extract (ORE) was prepared via ultrasonication-assisted ethanolic extraction and enriched through silica gel and macroporous adsorption resin chromatography to afford a non-/weakly polar fraction (ORE-S) and a polar fraction (ORE-N), respectively. This study aimed to (1) quantify major bioactive components (e.g., polyphenols, alkaloids, and terpenes) in ORE-S and ORE-N, (2) assess their antioxidant activities, (3) correlate compositional differences with antioxidant function, and (4) identify key antioxidant compounds along with their potential mechanisms of action. By integrating widely targeted metabolomics with network pharmacology, we not only elucidated how enrichment methods influence the antioxidant properties of ORE but also demonstrated the potential of ORE-N as a valuable source of bioactive compounds and natural antioxidants.

Aim: To investigate the effects and mechanisms of S-adenosylmethionine (SAM) from deer antler on improving depression-like behaviors in chronic unpredictable mild stress (CUMS) mice.
Methods: The CUMS method was used to establish a mouse depression model. The relationship between SAM and HIF-1α was analyzed by small molecule-protein docking and molecular dynamics simulation.

Herein we present the rapid development of LH168, a potent and highly selective chemical probe for WDR5, streamlined by utilizing a DEL-ML (DNA encoded library-machine learning) hit as the chemical starting point. LH168 was comprehensively characterized in bioassays and demonstrated potent target engagement at the WIN-site pocket of WDR5, with an EC of approximately 10 nM, a long residence time, and exceptional proteome-wide selectivity for WDR5. In addition, we present the X-ray co-crystal structure and provide insights into the structure-activity relationships (SAR).

Objective: This study aimed to investigate comorbidity patterns and potential pathogenic mechanisms in patients with Hashimoto's thyroiditis (HT).
Methods: Patients with HT who visited the outpatient clinic of the Thyroid Department at Dongzhimen Hospital, Beijing University of Chinese Medicine, between June 2021 and December 2024 were included. Association rule analysis and logistic regression analysis were performed using SPSS 25.

Introduction: Understanding how neural networks process complex patterns of information is crucial for advancing both neuroscience and artificial intelligence. To investigate fundamental principles of neural computation, we examined whether dissociated neuronal cultures, one of the most primitive living neural networks, exhibit regularity sensitivity beyond mere stimulus-specific adaptation and deviance detection.
Methods: We recorded activity to oddball electrical stimulation paradigms from dissociated rat cortical neurons cultured on high-resolution CMOS microelectrode arrays.
