Article Abstract
Purpose: The purpose of this study was to compare the efficiency of conventional screening and of the Spot™ Vision Screener (SVS)-based screening in detecting potential cases of amblyopia during the Visual examination in Three-Year-Old Health Screening Program (VTYOS), that need to be referred for comprehensive examination.
Study Design: Population-based cross-sectional study METHODS: This study introduced the SVS-based test to the VTYOS (which includes primary, secondary, and comprehensive examinations) of Sagae, Yamagata Prefecture, Japan. Children aged 3 years 6 months scheduled to undergo the secondary examination were subjected to both the SVS-based (evaluation of refractive error and eye alignment) and conventional screening test (questionnaire and visual acuity evaluation). Success rates, proportion of children who needed a comprehensive examination, rates of actual comprehensive examinations, and positive predictive value were determined and compared between conventional screening and SVS-based screening.
Results: There were 294 participants; the rate of success of SVS-based screening (99.7%) was higher than conventional screening (89.5%, p < 0.01). The proportion of participants found to need a comprehensive examination according to SVS-based findings (7.5%) was lower than that according to conventional screening-based findings (23.5%, p < 0.01). The positive predictive value of the SVS-based screening test (75.0%) was higher than that of the conventional screening test (31.6%, p < 0.01). SVS-based screening detected 2 cases of amblyopia in 225 cases that passed conventional screening.
Conclusion: The VTYOS should ideally add SVS-based screening to conventional screening.

The estrogen receptor (ER or ERα) remains the primary therapeutic target for luminal breast cancer, with current treatments centered on competitive antagonists, receptor down-regulators, and aromatase inhibitors. Despite these options, resistance frequently emerges, highlighting the need for alternative targeting strategies. We discovered a novel mechanism of ER inhibition that targets the previously unexplored interface between the DNA-binding domain (DBD) and ligand-binding domain (LBD) of the receptor.

The coupling between transition metal dichalcogenides (TMDCs) and SrTiO has recently emerged as a fertile platform for discovering interfacial phenomena, where particle interactions, lattice coupling, and dielectric screening give rise to interesting physical effects. These hybrid systems hold significant promise for two-dimensional (2D) electronics, ferroelectric state control, and metastable phase engineering. However, effective modulation of the interfacial electronic structure remains a critical challenge.

Background: Innovative antibiotic discovery strategies are urgently needed to successfully combat infections caused by multi-drug-resistant bacteria.
Methods: We employed a direct screening approach to identify compounds with antimicrobial and antimicrobial helper-drug activity against Gram-positive and Gram-negative bacteria. We used this platform in two different strains of methicillin-resistant (MRSA) and aminoglycoside-resistant strains of to screen for antimicrobials compounds, which potentiate the activity of aminoglycoside antibiotics.

Non-hydrogenative para-hydrogen-induced polarization (nhPHIP) has proven a powerful tool for the enhanced NMR detection of several classes of metabolites in complex mixtures. Particularly, compounds carrying an α-amino acid motif have been previously detected and quantified in biological samples and natural extracts at submicromolar concentrations using 2D nhPHIP NMR spectroscopy. This technique is here applied for the first time in a semi-targeted metabolomics NMR study on urine from patients suffering from Pyridoxine-Dependent Epilepsy (PDE), currently diagnosed by the presence of dilute unique biomarkers.

The prompt and accurate identification of pathogenic bacteria is crucial for mitigating the transmission of infections. Conventional detection methods face limitations, including lengthy processing, complex sample pretreatment, high instrumentation costs, and insufficient sensitivity for rapid on-site screening. To address these challenges, an aptamer (Apt)-sensor based on functionalized magnetic nanoparticles (MNPs) was developed for detecting Escherichia coli.
