AmpC/AmpD Resistance to Ceftolozane-Tazobactam
2026-08-17
Deroche and colleagues combined isogenic Pseudomonas aeruginosa mutants, sequential time-kill experiments, and semi-mechanistic PKPD modeling to separate inherited susceptibility changes from time-dependent adaptive resistance to ceftolozane-tazobactam. The study shows that AmpC G183D and AmpD H157Y mutations have distinct and strongly amplified effects when combined, providing a framework for interpreting resistance trajectories beyond MIC measurements.

Piroxicam and Deracoxib in Canine Mammary Cancer
2026-08-12
The reference study examined whether piroxicam and deracoxib directly inhibit growth of the CMT-U27 canine mammary carcinoma cell line, either alone or in combination. Using MTT viability testing and flow cytometry, the authors found stronger cytotoxicity, apoptosis, and G0/G1 accumulation with combined treatment, while also showing why these in vitro results require careful dose and translational interpretation.
