Dipiperazine‐Phenyl Derivatives Based on Convergent Molecular Platforms Can Reverse Multidrug Resistance in Gram‐Negative Bacteria by Inhibiting Efflux and Permeabilizing Cell Membranes

Advanced Science, EarlyView.
By integrating a convergent molecular platform strategy, this study designed a novel dual‐target C5 to combat multidrug‐resistant Gram‐negative bacteria. C5 synergistically enhances antibiotic efficacy by inhibiting efflux pumps and increasing bacterial membrane permeability.

Astrocytic PCBP1 Suppresses Ferroptosis to Restore Glutamatergic Homeostasis and Mitigate Stress‐Induced Depression in Male Mice

Advanced Science, EarlyView.
This study demonstrates that polyC‐RNA‐binding protein 1 (PCBP1) in ventral hippocampal astrocytes modulates depressive‐like behaviors by regulating glutathione peroxidase 4‐mediated ferroptosis and synaptic glutamatergic transmission. PCBP1 overexpression intervention in the chronic unpredictable mild stress model rescues behavioral deficits ...

Human Cytomegalovirus: detection of congenital and perinatal infection in Argentina [PDF]

, 2004
BACKGROUND: Human cytomegalovirus (CMV) is one of the most commonly found agents of congenital infections. Primary maternal infection is associated with risk of symptomatic congenital diseases, and high morbidity is frequently associated with very low ...

A Bioinstructive Injectable Hydrogel for Enhancing Intrinsic Regeneration through Cell Recruitment and Training

Advanced Science, EarlyView.
A bioinstructive injectable hydrogel enables sustained release of stromal cell–derived factor‐1 alpha (SDF‐1α) and stable retention of laminin through ionic and hydrophobic interactions. This dual‐signaling matrix promotes endogenous stem cell recruitment and training, supports angiogenesis, and enhances intrinsic regenerative processes in ischemic ...

Fe‐S Protein FDX1 Triggers Tumor‐Intrinsic Innate Immunity via Mitochondrial Nucleic Acids Release to Orchestrate Ferroptosis in CCRCC

Advanced Science, EarlyView.
Restoration of the mitochondrial Fe–S protein FDX1 suppresses clear cell renal cell carcinoma by coupling ferroptosis with tumor‐intrinsic innate immune activation. FDX1 induces mitochondrial dysfunction and mtDNA/mt‐dsRNA release, activating cGAS–STING and RIG‐I/MDA5–MAVS signaling to elicit type I interferon responses, thereby promoting antigen ...

Mutagenic Improvement of Xylanase Production from Xylanolytic Bacteria and its Phylogenetic Analysis

Microbiology Indonesia, 2013
This study was conducted to obtain xylanolytic mutants that have higher xylanase activity than their wildtype counterparts. A mutant with the best xylanolytic activity was selected and identified based on its 16S rRNA sequence.
