AmpC β-lactamases producing Gram-negative clinical isolates from a tertiary care hospital
Journal of Mahatma Gandhi Institute of Medical Sciences, 2016 Introduction: AmpC βlactamases are clinically significant since these confer resistance to cephamycins as well as other extended-spectrum cephalosporins and are not affected by βlactamase inhibitors.

The gene bolA regulates dacA (PBP5), dacC (PBP6) and ampC (AmpC), promoting normal morphology in Escherichia coli [PDF]
Molecular Microbiology, 2002 Summary The gene bolA has been shown to trigger the formation of osmotically stable round cells when overexpressed in stationary phase. We show that in poor growth conditions bolA is essential for normal cell morphology in stationary ...

Reversing Antibiotic Resistance: Strategies From Adjuvants to Innovative Therapeutics
MicrobiologyOpen, Volume 15, Issue 1, February 2026.Molecular reversal strategies against antibiotic resistance act through three mechanisms: inhibiting resistance gene function, blocking horizontal gene transfer, and modulating host defense. Emerging technologies, such as CRISPR‐Cas gene editing, photodynamic therapy, nanotechnology, and ecological competition, further strengthen these approaches ...

MicrobiologyOpen, Volume 15, Issue 1, February 2026.This study reveals estragole's bactericidal activity against MDR/XDR Gram‐negative pathogens. Synergy with meropenem and tobramycin was observed in > 88% of strains, reducing antibiotic MICs up to 16‐fold. Estragole represents a promising therapeutic adjuvant to enhance antibiotic efficacy and combat antimicrobial resistance.

Phenotypic and Molecular Characterization of Plasmid Mediated AmpC among Clinical Isolates of Klebsiella pneumoniae Isolated from Different Hospitals in Tehran [PDF]
Journal of Clinical and Diagnostic Research, 2015 Introduction: Klebsiella pneumoniae is one of the main opportunistic pathogens which can cause different types of infections. Production of beta-lactamases like AmpC and ESBL mostly lead to beta-lactam resistance in these Gram-Negative bacteria.

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.ABSTRACT As the need to reduce use in the building sector increases, thermally activated building systems (TABS) have gained attention for providing both comfort and energy efficiency. Their large thermal mass enables peak load shifting, making them suitable for demand response (DR).
