A Premature Termination of Human Epidermal Growth Factor Receptor Transcription in Escherichia coli

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Our success in producing an active epidermal growth factor receptor (EGFR) tyrosine kinase in Escherichia coli encouraged us to express the full‐length receptor in the same host. Despite its large size, we were successful at producing the full‐length EGFR protein fused to glutathione S‐transferase (GST) that was detected by Western blot analysis ...

Mechanistic Insights into Structure‐Driven Selectivity in CO2 Hydrogenation Over Cu‐Based Catalysts

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
In our work, DFT reveals that the CO2 hydrogenation reaction pathways on the copper surface are strongly influenced by the interaction of a formic acid‐based intermediate with the catalyst structure. This facet‐dependent behavior explains experimental trends of increased methanol selectivity with varying nanoparticle size and highlights the critical ...

In Vivo Detection of Staphylococcus aureus Infections Using Radiolabeled Antibodies Specific for Bacterial Toxins

International Journal of Biomedical Imaging, Volume 2024, Issue 1, 2024.
Purpose. The Gram‐positive Staphylococcus aureus bacterium is one of the leading causes of infection in humans. The lack of specific noninvasive techniques for diagnosis of staphylococcal infection together with the severity of its associated complications support the need for new specific and selective diagnostic tools.

Análisis térmico y espectrometría de masas en conductores protónicos (PVDF/H3PO2) para implementación en celdas de combustible

, 2018
Polyvinyl Difluoride and Hypophosphorous Acid (PVDF/H3PO2) membranes were prepared with different concentrations of acid. The differential scanning calorimetry (DSC) results showed a typical step of the glass transition around 250 K.

Metabolomic Analysis of the Effect of Lippia origanoides Essential Oil on the Inhibition of Quorum Sensing in Chromobacterium violaceum

Antibiotics, 2023
Bacteria can communicate through quorum sensing, allowing them to develop different survival or virulence traits that lead to increased bacterial resistance against conventional antibiotic therapy. Here, fifteen essential oils (EOs) were investigated for
