• AmpC/AmpD Resistance to Ceftolozane-Tazobactam

  2026-08-14

  Deroche and colleagues combined targeted mutation reconstruction, sequential time-kill experiments, and semi-mechanistic PKPD modeling to separate the immediate and adaptive components of Pseudomonas aeruginosa resistance to ceftolozane-tazobactam. The study shows that AmpC G183D and AmpD H157Y make distinct, strongly interacting contributions to resistance and that the same framework can clarify imipenem susceptibility changes.

• Leonurine Targets Endothelial STING in Cardiotoxicity

  2026-08-13

  This Advanced Science study identifies cardiac vascular endothelial cells as early sensors and amplifiers of doxorubicin-induced cardiomyopathy. It shows that leonurine interrupts an endothelial STING–NF-κB–NLRP3 inflammatory loop and limits extracellular-vesicle-mediated mitochondrial injury in cardiomyocytes, suggesting an upstream therapeutic strategy.

• Ferroptosis Signature and Atorvastatin in HCC

  2026-08-12

  The reference study combines a four-gene ferroptosis-related prognostic signature with Connectivity Map screening to identify Atorvastatin as a candidate treatment for hepatocellular carcinoma.
