Introduction: Dysfunction in amygdala networks has been implicated in major depressive disorder (MDD). Pharmacological treatments, such as esketamine and sertraline, are believed to exert their antidepressant effects by modulating amygdalar activity. This study aimed to investigate the relationship between changes in dynamic functional connectivity (dFC) within amygdala subregions and treatment outcomes, with a focus on identifying potential neuroimaging markers.

Background: Post-hepatectomy liver failure (PHLF) is a leading cause of perioperative mortality following liver resection. Early detection and prediction of clinically relevant post-hepatectomy liver failure (CR-PHLF) remain critical but challenging. Lactate has shown promise as a biomarker, but its predictive power when combined with other factors remains unclear.

Here, we present a copper-mediated magnetic molecularly imprinted polymer (Cu-mMIP) as dispersive solid-phase extracting material (dSPE) for fast, selective, and specific extraction of a metabolic biomarker vitamin B1 (VB1) in complex biological matrices. With emulsifier-free emulsion polymerization using styrene and itaconic acid as functional co-monomers, Cu as central atom, and FeO nanoparticles (NPs) as core, the resulted Cu-mMIP addresses VB1's structural challenges (conformational flexibility, hydrophilicity) while enabling rapid magnetic separation (< 10 s). The Cu-mMIP demonstrates exceptional specificity for VB1, achieving an imprinting factor of 5.

Translation reprogramming-induced dysregulation of protein synthesis is a widespread phenomenon in disease progression, especially in tumor cells, where there is abnormally active protein synthesis to support the increasing demands of oncogene expression. This aberrant translation process contributes to various malignant phenotypes of tumors. In the process of protein synthesis, transfer RNAs (tRNAs) transport amino acids to the ribosome according to the codon sequence on mRNA to synthesize the corresponding peptide chain.

Motivation: The structural complexities enable RNA to serve as a versatile molecular scaffold capable of binding small molecules with high specificity. Understanding these interactions is essential for elucidating RNA's role in disease mechanisms and developing RNA-targeted therapeutics. However, predicting RNA-small molecule binding sites remains a significant challenge due to their conformational flexibility, structural diversity, and the limited availability of high-resolution structural data.

Glucose oxidase (GOx), which specifically catalyzes glucose oxidation, has been widely employed in constructing various biosensors for clinical screening of diseases such as diabetes and tumors. However, current GOx-based glucose detection methods suffer from limitations including high costs and tedious multi-step procedures. In this work, we developed a facile green aqueous-phase synthesis of Au-doped MoS nanomaterials with dual-enzyme activities.

Background And Purpose: Obstructive sleep apnea (OSA) is linked to cognitive impairment and altered motor-related brain networks. This study examined functional connectivity (FC) changes in subregions of the primary motor cortex (M1) in patients with OSA and their association with sleep structure, cognition, and clinical features.

Methods: Sixty-five patients with OSA and 65 healthy controls (HC) participants matched in age and educational background were included.

Hepatocellular carcinoma (HCC) is one of the most prevalent and aggressive forms of liver cancer, with limited therapeutic options and a high recurrence rate. Traditional treatments include surgery and systemic therapy, but systemic therapy has side effects, such as poor specificity, systemic toxicity, and drug resistance. Herein, we designed a multimodal diagnostic and therapeutic-integrated nanosphere for packaging and delivering lenvatinib (LVN).

Two-dimensional (2D) semiconductors have been of great interest for phototransistors and neuromorphic devices in recent years because of their unique optical and electronic properties. However, the detectable spectral range and light absorption efficiency are limited for 2D-semiconductor-based phototransistors. Herein, we report a high-performance deep-ultraviolet (DUV) sensitive phototransistor by integrating molybdenum disulfide (MoS) with silicon carbide nanoparticles (SiC NPs) to form a van der Waals heterostructure (vdWH), which shows ultrahigh responsivity and detectivity, especially in the DUV spectral range.

Computational modeling is a tool for exploring both normal electrical propagation in healthy hearts and cardiac arrhythmias in patients. While numerous human ventricular cell models exist, the ten Tusscher (TT2) model is one of the most used for simulating ventricular arrhythmia. Recently, the Tomek model has been proposed, offering improved accuracy by better reproducing key depolarization, repolarization, and calcium dynamics in healthy ventricular cardiomyocytes.

Research Question: Can Gly[14]-humanin (HNG) improve cyclophosphamide-induced premature ovarian insufficiency (POI)?

Design: A POI model was induced in female rats by intraperitoneal injection of cyclophosphamide, followed by treatment with an intraperitoneal injection of HNG. Ovarian weight, ovarian index, regularity of the oestrous cycle, numbers of various types of follicle, hormone concentrations, and expression of the proliferation marker Ki67 were assessed in rats, and terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) staining was performed. The human ovarian granulosa cell line COV434 was exposed to the cyclophosphamide metabolite 4-hydroperoxy cyclophosphamide (4-HC), followed by HNG treatment.

systematic evolution of ligands by exponential enrichment (SELEX) emerged as a transformative technique for directly identifying aptamers within living organisms. Unlike traditional methods that often fail to capture the complexity of biological interactions in physiological environments, SELEX leverages whole living organisms as selection targets. This strategy significantly enhances the specificity, functionality, and physiological relevance of the selected aptamers, making them more viable for therapeutic, diagnostic, and imaging applications.
