• MnTBAP Chloride for Mitochondrial Redox Workflows

  2026-08-14

  MnTBAP Chloride helps researchers test whether mitochondrial superoxide contributes to oxidative injury, inflammation, and stress-related phenotypes. This guide translates cell, tissue, and chronic-stress findings into practical workflows, controls, and troubleshooting decisions.

• AmpC/AmpD Resistance to Ceftolozane-Tazobactam

  2026-08-13

  Deroche and colleagues combined isogenic mutant construction, sequential time-kill experiments, and semi-mechanistic PKPD modeling to separate the immediate and adaptive effects of ampC and ampD mutations in Pseudomonas aeruginosa. The study shows that the AmpC G183D and AmpD H157Y substitutions can act together to produce substantial ceftolozane-tazobactam resistance, while AmpC G183D also alters adaptive resistance to imipenem.
