Letters to editor regarding the article "P4HA2 contributes to head and neck squamous cell carcinoma progression and EMT through PI3K/AKT signaling pathway".

We have read the original article titled "P4HA2 contributes to head and neck squamous carcinoma progression and EMT through PI3K/AKT signaling pathway" by Yan-Ling Wu et al., which was published in the Medical Oncology journal, with great interest. This study provides valuable insights into the involvement of P4HA2 in the progression of head and neck squamous cell carcinoma (HNSCC), highlighting its potential as an oncogenic factor that promotes epithelial-mesenchymal transition (EMT), motility, invasion, and proliferation of cancer cells through the PI3K/AKT signaling pathway.

Hierarchically, Low Band Gap Nanohybrid InVO-CdS Heterojunction for Visible Light-Driven Toxic Organic Dye Degradations.

The synthesis of InVO-CdS heterojunction photocatalysts has been achieved by a novel two-step approach, including a microwave-assisted technique, followed by a moderate hydrothermal method, marking the first successful instance of such a synthesis. X-ray diffraction, field-emission scanning electron microscopy, elemental color mapping, high-resolution transmission electron microscopy, UV-vis diffuse reflectance spectroscopy, Raman analysis, photoluminescence, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller were employed to investigate the crystal structures, surface morphologies and particle sizes, chemical compositions, and optical characteristics of the as-synthesized materials. The research results indicated that the heterojunction InVO-CdS, as synthesized, consisted of InVO microrods with an average size of around 15 nm and cadmium sulfide (CdS) microflowers with a diameter of 1.

Design and construction of heterostructured ZnVO cubes and hexagons as an electrode material for high-performance asymmetric supercapacitor applications.

Hierarchical nanostructures have harvested noteworthy attention lately owing to their remarkable capabilities in the fields of energy storing and transformation, catalysis, and electrical devices. We established an effort less and template-free synthetic method to create hierarchical hetero nanostructures of ZnVO, taking into account the benefits of hierarchical nanostructures, we investigated the performance of HNs (Hierarchical Nanostructures) as electrochemical supercapacitors. Electrochemical tests were tested in a 6 M KOH solution to assess their capabilities.

Facile Synthesis of Phase Tunable MoO₃ Nanostructures and Their Electrochemical Sensing Properties.

MoO₃ nanostructures with tunable phases such as -MoO₃, -MoO₃ and their mixed phases were synthesized via a simple solid state decomposition method and employed as electrocatalyst for the detection of biomolecule. The phase and crystal structure of the synthesized MoO₃ nanostructures were confirmed through X-ray diffraction (XRD) studies. The MoO₃ nanostructures were also characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and UV-Vis spectroscopy for their structural, chemical state and optical properties, respectively.

Synthesis and characterization of chromium(III) Schiff base complexes: antimicrobial activity and its electrocatalytic sensing ability of catechol.

A series of acyclic Schiff base chromium(III) complexes were synthesized with the aid of microwave irradiation method. The complexes were characterized on the basis of elemental analysis, spectral analysis such as UV-Visible, Fourier transform infrared (FT-IR), nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) spectroscopies and electrospray ionization (ESI) mass spectrometry. Electrochemical analysis of the complexes indicates the presence of chromium ion in +3 oxidation state.

Nanomolar determination of 4-nitrophenol based on a poly(methylene blue)-modified glassy carbon electrode.

A poly(methylene blue)-modified glassy carbon electrode (PMB/GCE) was fabricated by electropolymerisation of methylene blue on a GCE and further utilized to investigate the electrochemical determination of 4-nitrophenol (4-NP) by cyclic voltammetry (CV), differential pulse voltammetry and chronocoulometry. The morphology of the PMB on GCE was examined using a scanning electron microscope (SEM). An oxidation peak of 4-NP at the PMB modified electrode was observed at 0.
