Introduction: The rise of antibiotic resistance poses a critical challenge to public health, particularly in managing infections caused by non-fermenting bacteria such as and This study aimed to determine the prevalent multi-drug resistance among non-fermentative Gram-negative bacteria isolated from hospitalized patients in a tertiary care center.
Material And Methods: A retrospective analysis was undertaken using one year of data from 2022 to 2023 to evaluate the antimicrobial resistance (AMR) profiles of and . The study assessed antibiotic resistance patterns, including piperacillin/tazobactam, carbapenems (imipenem, meropenem), ciprofloxacin, and colistin.
Results: The analysis revealed resistance of to various antibiotics shows that piperacillin/tazobactam exhibited the highest resistance rate at 32% (181/565), while colistin exhibits the lowest at 5.6% (32/565). For , the resistance varies significantly among antibiotics, with piperacillin/tazobactam and ciprofloxacin showing the highest resistance rates at 56.8% (128/225) and 68% (153/225), respectively. In contrast, colistin is highly effective, with only 0.8% (2/225) resistance, and amikacin also demonstrates low resistance at 9.7% (22/225).
Conclusion: The growing trend of multi-drug and extensive drug resistance among non-fermenters such as and necessitates urgent action. Establishing strict antibiotic policies, continuous monitoring of resistance patterns, and investment in antimicrobial research are imperative to combat the limited treatment options and manage these pathogens effectively.

Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models.

Strain sensing fabrics are able to sense the deformation of the outside world, bringing more accurate and real-time monitoring and feedback to users. However, due to the lack of clear sensing mechanism for high sensitivity and high linearity carbon matrix composites, the preparation of high performance strain sensing fabric weaving is still a major challenge. Here, an elastic polyurethane(PU)-based conductive fabric(GCPU) with high sensitivity, high linearity and good hydrophobicity is prepared by a novel synergistic conductive network strategy.
