Data_Sheet_1_Distinct Roles of Outer Membrane Porins in Antibiotic Resistance and Membrane Integrity in Escherichia coli.docx

, 2019
A defining characteristic of Gram-negative bacteria is the presence of an outer membrane, which functions as an additional barrier inhibiting the penetration of toxic chemicals, such as antibiotics.

Alloyed Versus Physically Mixed Bimetallic Nanoparticle PLA Composites: Structure and Antimicrobial Performance

SPE Polymers, Volume 7, Issue 4, October 2026.
Schematic representation of the fabrication and evaluation of PLA‐based bimetallic nanoparticle composites. ABSTRACT In this work, polylactic acid (PLA) based nanocomposites containing bimetallic nanoparticle systems were made using the injection molding method to compare the antimicrobial behavior of alloyed nanoparticles and those physically mixed to

Outer membrane permeability of Pseudomonas aeruginosa through β-lactams: new evidence on the role of OprD and OpdP porins in antibiotic resistance

Microbiology Spectrum
Gram-negative bacteria are a major concern for public health, particularly due to the continuous rise of antibiotic resistance. A major factor that helps the development of resistance is the outer membrane that is essential since it acts as a strong ...

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential

Angewandte Chemie International Edition, Volume 65, Issue 39, 21 September 2026.
Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Role of Porins in Iron Uptake by Mycobacterium smegmatis

, 2010
Many bacteria rely on siderophores to extract iron from the environment. However, acquisition of iron-loaded siderophores is dependent on high-affinity uptake systems that are not produced under high-iron conditions.

Nanomaterial Strategies for Pulmonary Delivery of Immunotherapeutics in Lung Cancer Treatment

Advanced Healthcare Materials, Volume 15, Issue 34, 11 September 2026.
Inhalable immunotherapeutic nanomedicines enable organ‐selective immune modulation by overcoming pulmonary delivery barriers and concentrating therapy within lung tumors. This Review defines how nanomaterial properties govern airway deposition, retention, cellular partitioning, and immune activation across vaccines, checkpoint blockade, STING agonists,
