Table1_Potential therapeutic strategies for quercetin targeting critical pathological mechanisms associated with colon adenocarcinoma and COVID-19.XLSX
Patients with colon adenocarcinoma (COAD) are at a higher probability of infection with COVID-19 than healthy individuals. However, there is no globally accepted treatment protocol for patients with COAD/COVID-19. Quercetin has been found to have significant antitumor, antiviral and anti-inflammatory effects in several studies. Therefore, this study sought to evaluate the potential of quercetin as the agent for COAD/COVID-19 and to explore its mechanisms. We used bioinformatics algorithms to obtain COAD/COVID-19-related genes (CCRG) from COAD-related transcriptome data and COVID-related transcriptome sequencing data, and used these genes to construct a COAD prognostic model. We intersected the CCRG with the therapeutic target genes of quercetin and obtained a total of 105 genes (potential target genes of quercetin for the treatment of COAD/COVID-19). By constructing a protein-protein interaction (PPI) network, we ascertained FOS, NFKB1, NFKB1A, JUNB, and JUN as possible core target genes of quercetin for the treatment of COAD/COVID-19. Bioinformatic analysis of these 105 genes revealed that the mechanisms for quercetin the treatment of COAD/COVID-19 may be associated with oxidative stress, apoptosis, anti-inflammatory, immune, anti-viral and multiple pathways containing IL-17, TNF, HIF-1. In this study, we constructed a prognostic model of COAD/COVID19 patients by using CCRG and elucidated for the first time the potential target genes and molecular mechanisms of quercetin for the treatment of COAD/COVID-19, which may benefit the clinical treatment of COAD/COVID-19 patients. However, no clinical trials have yet been conducted to further validate the findings, but this will be the future direction of our research.</p
Sb<sup>3+</sup>-Doped Indium-Based Metal Halide (Gua)<sub>3</sub>InCl<sub>6</sub> with Efficient Yellow Emission
In recent years, low-dimensional organic–inorganic
hybrid
metal halides (OIHMHs) have shown excellent photophysical properties
due to their quantum structure, adjustable energy levels, and energy
transfer between inorganic and organic components, which have attracted
extensive attention from researchers. Herein, we synthesize a zero-dimensional
(0D) OIHMH, Sb3+:(Gua)3InCl6, by
introducing Sb3+ into (Gua)3InCl6, which undergoes a significant enhancement of the emission peak
at 580 nm with the photoluminescence quantum yield (PLQY) boosted
from 17.86 to 95.72% when excited at 340 nm. This boost in photoluminescence
of the doped sample was studied by combining ultrafast femtosecond
transient absorption, temperature-dependent photoluminescence (PL)
spectra, and density functional theory (DFT) calculation, revealing
the process of self-trapped exciton (STE) recombination to emit light
at both Sb and In sites in this 0D structure simultaneously. This
material with the lowest dark STE level at the In site for emission
in the undoped sample can amazingly yield very strong emission in
the doped sample, which has never been observed before. Finally, we
tested its application in a photoelectric device. This work not only
helps to gain a deeper understanding of the formation of STEs in In-based
halides but also plays a certain guiding role in the design of new
luminescent materials

Enhanced Metal–Insulator Transition Performance in Scalable Vanadium Dioxide Thin Films Prepared Using a Moisture-Assisted Chemical Solution Approach
Vanadium
dioxide (VO<sub>2</sub>) is a strong-correlated metal–oxide
with a sharp metal–insulator transition (MIT) for a range of
applications. However, synthesizing epitaxial VO<sub>2</sub> films
with desired properties has been a challenge because of the difficulty
in controlling the oxygen stoichiometry of VO<sub><i>x</i></sub>, where <i>x</i> can be in the range of 1 < <i>x</i> < 2.5 and V has multiple valence states. Herein, a
unique moisture-assisted chemical solution approach has been developed
to successfully manipulate the oxygen stoichiometry, to significantly
broaden the growth window, and to significantly enhance the MIT performance
of VO<sub>2</sub> films. The obvious broadening of the growth window
of stoichiometric VO<sub>2</sub> thin films, from 4 to 36 °C,
is ascribed to a self-adjusted process for oxygen partial pressure
at different temperatures by introducing moisture. A resistance change
as large as 4 orders of magnitude has been achieved in VO<sub>2</sub> thin films with a sharp transition width of less than 1 °C.
The much enhanced MIT properties can be attributed to the higher and
more uniform oxygen stoichiometry. This technique is not only scientifically
interesting but also technologically important for fabricating wafer-scaled
VO<sub>2</sub> films with uniform properties for practical device
applications
