Abstract
Pathogenic bacteria are closely associated with the occurrence, development and metastasis of oral squamous cell carcinoma (OSCC). Antibacterial therapy has been considered an enhancement strategy to suppress bacteria-associated tumors and promote anti-tumor immune responses. Herein, we developed an injectable adhesive hydrogel, PNIPAM/DL@TIR, for the in situ photothermal ablation and robust stimulation of antitumor immunity against OSCC colonized by Porphyromonas gingivalis (Pg), one of the major oral pathogenic bacteria. PNIPAM/DL@TIR, composed of poly(N-isopropylacrylamide), demethylated lignin, and TAT peptide-conjugated IR820, was prepared using a simple dissolve-dry-swell solvent exchange method. Upon 808 nm laser irradiation, PNIPAM/DL@TIR exerted photothermal effects to ablate Pg-colonized OSCC and generate dual tumor and bacterial antigens. Owing to its large number of catechol groups, PNIPAM/DL@TIR efficiently captured these antigens to form an in situ antigen repository, thereby eliciting robust and durable antitumor immune responses. Proteomic analysis revealed that the captured antigens comprised both tumor neoantigens and bacterial antigens. The catechol groups endowed PNIPAM/DL@TIR with antioxidant activity, which was also conducive to stimulating antitumor immunity. Altogether, this study develops an injectable adhesive hydrogel and provides a combination strategy for treating bacteria-associated OSCC. STATEMENT OF SIGNIFICANCE: In this study, we developed an injectable adhesive hydrogel, PNIPAM/DL@TIR, for in situ photothermal ablation and robust stimulation of antitumor immunity against OSCC colonized by Porphyromonas gingivalis, one of the major oral pathogenic bacteria. PNIPAM/DL@TIR, which consists of poly(N-isopropylacrylamide), demethylated lignin, and TAT peptide-conjugated IR820 exhibited outstanding photothermal performance. Owing to the presence of catechol groups, PNIPAM/DL@TIR has good bioadhesive properties and can capture protein antigens to form in situ antigen repository, thus initiating robust and long-term antitumor immune responses. In addition, PNIPAM/DL@TIR exhibited strong antioxidant activity that is favorable for promoting antitumor immunity. In the mouse model of OSCC with bacterial infection, PNIPAM/DL@TIR not only ablated the primary tumors upon NIR laser irradiation, but also induced tumor and bacterial vaccination in situ to suppress distant tumors and lung metastasis.

Abstract
In this work, we present a density functional theory benchmark on antioxidant-related properties for a series of six polyphenols that are well-known antioxidants: caffeic acid, cyanidin, ellagic acid, gallic acid, myricetin, and phloretin. Computations on the 24 O-H bond dissociation enthalpies (BDEs) and 6 ionization potentials (IPs) were performed using twenty-three exchange-correlation functionals combined with four different basis sets in the gas-phase, water, and methanol; calibration against the Domain-based Local Pair Natural Orbital CCSD(T) (DLPNO-CCSD(T)) approach was employed. Mean absolute deviation (MAD) as well as linear fitting results suggested the LC-PBE approach as the most suitable for O-H BDEs in the gas-phase. The LC-PBE, M06-2X, and M05-2X results presented the smallest MADs for O-H BDEs when compared to the reference, in water. The LC-PBE results had the smallest MADs for IPs in the gas-phase while M05-2X, M06-2X, LC-PBE, and LC-ωPBE exhibited the best results for MAD in water. We expect the outcomes from the present work will serve as general guidance for researchers working in the field.

Abstract
Polyphenols, an important class of natural products, are widely distributed in plant-based foods. These compounds are endowed with several biological activities and exert protective effects in various physiopathological contexts, including cancer. We herein investigated novel potential mechanisms of action of polyphenols, focusing on the proteasome, which has emerged as an attractive therapeutic target in cancers such as multiple myeloma. We carried out a structure-based virtual screening study using the DrugBank database as a repository of FDA-approved polyphenolic molecules. Starting from 86 polyphenolic compounds, based on the theoretical binding affinity and the interactions established with key residues of the chymotrypsin binding site, we selected 2 promising candidates, namely Hesperidin and Diosmin. The further assessment of the biologic activity highlighted, for the first time, the capability of these two molecules to inhibit the β5-proteasome activity and to exert anti-tumor activity against proteasome inhibitor-sensitive or resistant multiple myeloma cell lines.

Euphorbia royleana Boiss Derived Silver Nanoparticles and Their Applications as a Nanotherapeutic Agent to Control Microbial and Oxidative Stress-Originated Diseases.

Abstract
Nanotechnology is one of the most advance and multidisciplinary fields. Recent advances in nanoscience and nanotechnology radically changed the way we diagnose, treat, and prevent various diseases in all aspects of human life. The use of plants and their extracts is one of the most valuable methods towards rapid and single-step protocol preparation for various nanoparticles, keeping intact "the green principles" over the conventional ones and proving their dominance for medicinal importance. A facile and eco-friendly technique for synthesizing silver nanoparticles has been developed by using the latex of Euphorbia royleana as a bio-reductant for reducing Ag+ ions in an aqueous solution. Various characterization techniques were employed to validate the morphology, structure, and size of nanoparticles via UV-Vis spectroscopy, XRD, SEM, and EDS. FTIR spectroscopy validates different functional groups associated with biomolecules stabilizing/capping the silver nanoparticles, while SEM and XRD revealed spherical nanocrystals with FCC geometry. The results revealed that latex extract-mediated silver nanoparticles (LER-AgNPs) exhibited promising antibacterial activity against both gram-positive and -negative bacterial strains (Bacillus pumilus, Staphylococcus aureus, E. coli, Pseudomonas aeruginosa, and Streptococcus viridians). Both latex of E. royleana and LER-AgNPs were found to be potent in scavenging DPPH free radicals with respective EC50s and EC70s as 0.267% and 0.518% and 0.287% and 0.686%. ROSs produced in the body damage tissue and cause inflammation in oxidative stress-originated diseases. H2O2 and OH* scavenging activity increased with increasing concentrations (20-100 μg/mL) of LER-AgNPs. Significant reestablishment of ALT, AST, ALP, and bilirubin serum levels was observed in mice intoxicated with acetaminophen (PCM), revealing promising hepatoprotective efficacy of LER-AgNPs in a dose-dependent manner.

Urolithin A's Antioxidative, Anti-Inflammatory, and Antiapoptotic Activities Mitigate Doxorubicin-Induced Liver Injury in Wistar Rats. Biomedicines 2023; 11:biomedicines11041125.

Abstract
Human colon microbiota produce a metabolite called urolithin A (URO A) from ellagic acid and linked compounds, and this metabolite has been demonstrated to have antioxidant, anti-inflammatory, and antiapoptotic activities. The current work examines the various mechanisms through which URO A protects against doxorubicin (DOX)-induced liver injury in Wistar rats. In this experiment, Wistar rats were administered DOX intraperitoneally (20 mg kg-1) on day 7 while given URO A intraperitoneally (2.5 or 5 mg kg-1 d-1) for 14 days. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma glutamyl transferase (GGT) were measured. Hematoxylin and eosin (HE) staining was used to evaluate histopathological characteristics, and then antioxidant and anti-inflammatory properties were evaluated in tissue and serum, respectively. We also looked at how active caspase 3 and cytochrome c oxidase were in the liver. The findings demonstrated that supplementary URO A therapy clearly mitigated DOX-induced liver damage. The antioxidant enzymes SOD and CAT were elevated in the liver, and the levels of inflammatory cytokines, such as TNF-α, NF-kB, and IL-6, in the tissue were significantly attenuated, all of which complemented the beneficial effects of URO A in DOX-induced liver injury. In addition, URO A was able to alter the expression of caspase 3 and cytochrome c oxidase in the livers of rats that were subjected to DOX stress. These results showed that URO A reduced DOX-induced liver injury by reducing oxidative stress, inflammation, and apoptosis.
