Synergy of PMBN and closantel against mcr-1-carrying multidrug- resistant E. coli and Salmonella via membrane permeabilization- driven accumulation and metabolic disruption

This study demonstrates that combining polymyxin B nonapeptide (PMBN) with closantel restores potent bactericidal activity against mcr-1-carrying multidrug-resistant *E. coli* and *Salmonella* by permeabilizing the outer membrane to drive intracellular drug accumulation, leading to ATP depletion, metabolic collapse, and effective in vivo therapeutic outcomes.

Protein expression of short-chain dehydrogenases/reductases and their inducibility by flubendazole in Haemonchus contortus

This study presents the first targeted proteomic characterization of short-chain dehydrogenases/reductases (SDRs) in *Haemonchus contortus*, revealing sex-dependent expression patterns and identifying specific SDR isozymes that exhibit both constitutive overexpression in benzimidazole-resistant strains and inducibility by flubendazole, suggesting their potential role in anthelmintic adaptation.

Molecular Polymorphism and Evolution of CYP736 Cytochrome P450 Monooxygenase Genes across Wild Vitis Species and Muscadinia rotundifolia

This study characterizes the molecular polymorphism and evolution of CYP736 cytochrome P450 genes across wild *Vitis* species and *Muscadinia rotundifolia*, revealing that while these genes are under purifying selection with high sequence conservation, the resistance to Pierce's disease observed in specific hybrids is likely driven by regulatory mechanisms rather than coding-sequence divergence.

Maternal Social Support Reshapes the Offspring Brain Transcriptome to Buffer Prenatal Stress in Mice

This study demonstrates that while maternal social support in mice effectively normalizes behavioral and hormonal deficits caused by prenatal stress, it does so not by restoring the offspring's brain transcriptome to a baseline state, but by activating a distinct, amplified adaptive transcriptional program that reshapes resilience.
