This study was conducted to investigate the effect of trans-resveratrol (t-RSV) at a subinhibitory concentration (sub-MIC-t-RSV) on phenotypic and genotypic expression of virulence factors of clinical isolates of UPEC and develop a nanoformulation of t-RSV. Fifty-five clinical UPEC strains were investigated for the presence of virulence factors by phenotypic methods and PCR detection of virulence genes.

Article Synopsis
- Nanostructured iron disulfide (FeS) was deposited on regenerated cellulose (RC) and carbon nanotube (CNT) composite films to create RC/CNT/FeS composite films, which benefited from the porous structure and high conductivity of the substrate.
- The introduction of polypyrrole (PPy) enhanced the composite's conductivity and cycling stability, resulting in a notable electrochemical performance with an areal capacitance of 6543.8 mF cm at low current density and excellent capacitance retention over 10,000 cycles.
- A supercapacitor using these composite electrodes achieved high energy and power densities, indicating their potential for high-performance energy storage applications.
Covalent organic frameworks (COFs) are a novel family of porous crystalline materials utilized in various advanced applications. However, applying COFs as a hazardous organic acid gas sensor is substantial but still challenging. Herein, a phenylenediamine-based covalent organic framework (TPDA-TPB COF) featuring excellent crystallinity, ultrastable thermal stability, and high surface area was successfully constructed.
