Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Fluoroquinolone Efficacy against Tuberculosis Is Driven by Penetration into Lesions and Activity against Resident Bacterial Populations. [PDF]

, 2019
Fluoroquinolones represent the pillar of multidrug-resistant tuberculosis (MDR-TB) treatment, with moxifloxacin, levofloxacin, or gatifloxacin being prescribed to MDR-TB patients.

Endogenous melatonin partial metabolic clearance as a potential endogenous marker of CYP1A2 activity

British Journal of Clinical Pharmacology, EarlyView.
Aims Cytochrome P450 1A2 (CYP1A2) exhibits substantial interindividual variability, necessitating appropriate phenotyping strategies for personalized pharmacotherapy. This study evaluated endogenous melatonin partial metabolic clearance (CLm(MEL)), calculated from urinary 6‐hydroxymelatonin (6‐O‐MEL) excretion and plasma melatonin (MEL) exposure, as a ...

Mechanistic elucidation of HFIP‐enabled C–Cl bond activation in the synthesis of tetrahydroquinoline derivatives

Bulletin of the Korean Chemical Society, EarlyView.
Mechanistic studies reveal that hexafluoroisopropanol (HFIP) enables C–Cl activation of propargylic halides by stabilizing ion pairs and enhancing effective Brønsted acidity. This cooperative solvent effect allows access to cationic intermediates and promotes cascade formation of tetrahydroquinolines through cyclization and disproportionation ...

Consumption of antibiotics at St Luke’s Hospital : a critical factor behind the local prevalence of antimicrobial resistance? [PDF]

, 2006
The intensity of antibiotic use in hospital settings is recognised as possibly the most important factor for the selection of antimicrobial resistance. Hospitals are therefore being encouraged to undertake surveillance and benchmarking of antimicrobial ...
