High-Throughput Screening of 3-Dimensional Co-culture Hair Follicle Mimetic Tissue with an Enhanced Extracellular Matrix for the Screening of Hair Growth-Promoting Compounds.

Hair follicle cells reside within a complex extracellular matrix (ECM) environment in vivo, where physical and chemical cues regulate their behavior. The ECM is crucial for hair follicle development and regeneration, particularly through epithelial-mesenchymal interactions. Current in vitro models often fail to replicate this complexity, leading to inconsistencies in evaluating hair loss treatments.

Impact of Artificial Intelligence on Polyp Size and Surveillance Colonoscopy: A Phantom Study.

Background Artificial intelligence (AI) is a hot topic in the world of medicine. AI may be useful in identifying and sizing polyps, which influence surveillance intervals. Therefore, we examined polyp size estimation by AI using a survey study.

A novel histologic index for polyomavirus nephropathy in comparison with the Banff scoring system: Clinical validation, prognostic implication, and correlation with plasma viral load.

BK Polyomavirus nephropathy (PVN) with definitive diagnosis on biopsy, presents incidentally or with varying degrees of graft dysfunction. Banff working group on PVN has proposed a novel scoring system in renal biopsies, to identify patients with higher risk of graft failure. In this study, we attempted to validate the Banff scoring system at index biopsies and correlate with a novel index score, plasma BK-virus load and graft outcome.

Stomach and duodenal ulcer as a cause of death in patients with cancer: a cohort study.

Introduction: Non-cancer deaths are now becoming a significant threat to the health of cancer patients. Death from stomach and duodenal ulcer is linked to cancer due to the side effects of treatment and its pathogenesis. However, guidelines for identifying cancer patients at the highest risk of death from stomach and duodenal ulcer remain unclear.

Bioluminescent Pseudomonas aeruginosa and Escherichia coli for whole-cell screening of antibacterial and adjuvant compounds.

Continued efforts to discover new antibacterial molecules are critical to achieve a robust pre-clinical pipeline for new antibiotics. Screening of compound or natural product extract libraries remains a widespread approach and can benefit from the development of whole cell assays that are robust, simple and versatile, and allow for high throughput testing of antibacterial activity. In this study, we created and validated two bioluminescent reporter strains for high-throughput screening, one in Pseudomonas aeruginosa, and another in a hyperporinated and efflux-deficient Escherichia coli.
