Summary: A multi-amplified electro-chemiluminescence aptasensor was developed for efficient recognition of the tumor marker CA125 in ovarian cancer. The sensor utilizes a tetrahedral DNA nanostructure and gold nanoparticles/Ru(bpy)32+/metal-organic framework signal probe for enhanced detection. The aptasensor shows high sensitivity and reliability, making it suitable for clinical analysis of CA125 detection.

Summary: This research work investigates the time evolution of electrical properties of gram-positive and gram-negative bacteria in the presence of methyl violet and Lugol. The results show that the impedance magnitude decreases with an increasing bacterial population for both strains, but the rate of impedance magnitude variation over time is different between gram-positive and gram-negative bacteria. These findings suggest that the time evolution of electrical impedance spectra can be used to differentiate Staphylococcus aureus from Escherichia coli bacteria.

Summary: Chemoresistance, a major challenge in cancer treatment, is associated with the cellular glutathione-related detoxification system. A study has identified GSTP1 enzyme as critical in the inactivation of anticancer drugs and suggests the need for GSTP1 inhibitors to combat chemoresistance. Through molecular docking and simulations, the study found that quercetin 7-O-beta-D-glucoside showed promise as a potential candidate for addressing chemoresistance in cancer patients.

Summary: The electrochemical properties of three oxazine fluorophores, ATTO655, ATTO680 and ATTO700, were investigated on gold electrodes. These fluorophores exhibit reversible or quasi-reversible voltammetric behavior depending on the pH. ATTO655, in particular, showed promising performance as a redox label for electrochemical nucleic acid sensing without affecting DNA folding. Hybridization experiments showed significant signal variation between single-stranded DNA and double-stranded DNA.

Summary: This study aims to identify biomarkers for non-small cell lung cancer (NSCLC) using copy number variation (CNV) data. A novel deep learning architecture, XL1R-Net, is proposed to improve the classification accuracy for NSCLC subtyping. Twenty NSCLC-relevant biomarkers are uncovered using explainable AI (XAI)-based feature identification. The results show that the identified biomarkers have high classification performance and clinical relevance. Additionally, twelve of the biomarkers are potentially druggable and eighteen of them have a high probability of predicting NSCLC patients' survival likelihood according to the Drug-Gene Interaction Database and the K-M Plotter tool, respectively. This research suggests that investigating these seven novel biomarkers can contribute to NSCLC therapy, and the integration of multiomics data and other sources will help better understand NSCLC heterogeneity.
