Discovery of a Pseudomonas aeruginosa-specific small molecule targeting outer membrane protein OprH-LPS interaction by a multiplexed screen.

The surge of antimicrobial resistance threatens efficacy of current antibiotics, particularly against Pseudomonas aeruginosa, a highly resistant gram-negative pathogen. The asymmetric outer membrane (OM) of P. aeruginosa combined with its array of efflux pumps provide a barrier to xenobiotic accumulation, thus making antibiotic discovery challenging.

Generation and characterization of three induced pluripotent stem cell lines for modeling coronary artery vasospasm.

Coronary artery vasospasm (CAV) is characterized by transient constriction of epicardial coronary arteries leading to angina. Its disease mechanisms are multifactorial but has centered mostly on endothelial dysfunction and smooth muscle hyperreactivity. To facilitate the investigation of these mechanisms in cell culture, we generated and characterized three induced pluripotent stem cell (iPSC) lines from patients with CAV.

SHAPE: A visual computing pipeline for interactive landmarking of 3D photograms and patient reporting for assessing craniosynostosis.

3D photogrammetry is a cost-effective, non-invasive imaging modality that does not require the use of ionizing radiation or sedation. Therefore, it is specifically valuable in pediatrics and is used to support the diagnosis and longitudinal study of craniofacial developmental pathologies such as craniosynostosis - the premature fusion of one or more cranial sutures resulting in local cranial growth restrictions and cranial malformations. Analysis of 3D photogrammetry requires the identification of craniofacial landmarks to segment the head surface and compute metrics to quantify anomalies.

Emotional Competence of Healthcare Workers and Its Impact on Patient Loyalty in Vietnamese Hospitals.

Objective: To evaluate the effect of healthcare employees' emotional competence (EC) on patient loyalty in public and private hospitals in Ho Chi Minh City, with a focus on the mediating roles of respect, trust, and rapport.

Method: A survey of 244 patients measured respect, trust, rapport, EC, and patient loyalty using a 5-point Likert scale. Structural equation modeling (SEM) was applied to assess the relationships between EC and patient loyalty, comparing results between public and private hospitals.

A Versatile Drift-Free Super-Resolution Imaging Method via Oblique Bright-Field Correlation.

High-resolution optical microscopy, particularly super-resolution localization microscopy, requires precise real-time drift correction to maintain constant focus at nanoscale precision during the prolonged data acquisition. Existing methods, such as fiducial marker tracking, reflection monitoring, and bright-field image correlation, each provide certain advantages but are limited in their broad applicability. In this work, a versatile and robust drift correction technique is presented for single-molecule localization-based super-resolution microscopy.
