Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

open access: yesAdvanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

open access: yesAdvanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Identification of a Nonribosomal Peptide Analog With Activity Against Multiple Gram‐Positive Bacteria via a Synthetic Bioinformatic Natural Product Discovery Approach

open access: yesAdvanced Science, EarlyView.
The genome of Rhodococcus erythropolis D‐1 was analyzed by bioinformatic tools to mine a novel nonribosomal peptide synthetase (NRPS) gene cluster. A nonribosomal peptide analog ZURJC5 associated with the NRPS was chemically synthesized. Through structure‐activity relationship studies, ZURJC28 was ultimately obtained and showed antibacterial activity ...

Accelerating Biosensor Discovery: A Computationally‐Driven Pipeline for Microplastics Monitoring

open access: yesAdvanced Intelligent Discovery, EarlyView.
A computationally guided pipeline unites molecular simulation, synthetic biology, electrochemical engineering, and machine learning to accelerate biosensor discovery. A Bacillus anthracis carbohydrate‐binding module is used to develop a high‐performance micro‐ and nanoplastics sensor with greatly reduced error and variability.

Assessing the effect of high doses of ampicillin on five marine and freshwater phytoplankton species: a biodegradation perspective

open access: yes, 2019
Previous studies have identified several effects of antibiotic exposure at doses typically found in natural water (~μg). However, high doses of antibiotics can be found near wastewater treatment plants, and antibiotic concentrations in natural ...

Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.
