Background: Understanding the intricate tumor microenvironment (TME) is crucial for elucidating the mechanisms underlying the progression of cervical squamous cell carcinoma (CSCC) and its response to anti-PD-1 therapy.
Methods: In this study, we characterized 50,649 cells obtained from the CSCC for single-cell RNA sequencing and integrated bulk sequencing data from The Cancer Genome Atlas (TCGA) and clinical samples to explore their cell composition, metabolic processes, signaling pathways, specific transcription factors, lineage tracking and response to immunotherapy. In vivo experiments were performed to validate the function of key cell subsets.
The electrocatalytic oxidation of benzyl alcohol to benzoic acid is a process that often requires high voltage, leading to increased energy consumption, side reactions (oxygen evolution reaction (OER)), and catalyst degradation. Herein, our study introduces a novel approach. We demonstrate that a PtZn-ZnO catalyst featuring a PtZn intermetallic structure with abundant PtZn-ZnO interfaces on the surface allows for the electrocatalytic oxidation of benzyl alcohol to benzoic acid with an impressive selectivity of 99.

We synthesized gold nanomaterials with distinct single-crystal facets, {111} in octahedra (OC), {100} in nanocubes (NCs), and {110} in rhombic dodecahedra (RD), to investigate the facet-dependent HMF oxidation. The Au RD achieved the spontaneous oxidation of HMF to HMFCA with stoichiometric hydrogen production, maintaining 95% carbon balance, 91% yield, and 98% selectivity.

Heterogeneous catalysts with highly dispersed active particles on supports often face stability challenges during high-temperature industrial applications. The ex-solution strategy, which involves in situ extrusion of metals to form socketed particles, shows potential for addressing this stability issue. However, a deeper understanding of the relationship between the socketed geometry of these partially embedded nanoparticles and their catalytic performance is still lacking.

To explore the potential of modifying F protein cleavage activity to enhance antitumor effects, we constructed a recombinant NDV LaSota strain by replacing its F protein cleavage site with that from the mesogenic Beaudette C (BC) strain using reverse genetics techniques. The resulting virus, rLaSota-BC-RFP, demonstrated significantly enhanced infectivity and tumor cell suppression on the murine melanoma B16F10 cell, characterized by higher cytotoxicity and increased apoptosis compared to its parental strain, rLaSota-RFP.

Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation.
View Article and Find Full Text PDFA fluorescence and colorimetric dual-signal sensing system for the determination of ascorbic acid (AA) in complex media was developed by using 5,10,15, 20-tetrakis(4-sulfonyl) porphyrin (TSPP) as a sensing probe and sodium 2,6-dichloroindophenol (DCIP) as a bridge. A fluorescence resonance energy transfer (FRET) effect occurred when DCIP was added to the TSPP solution, resulting in the quenching of the fluorescence signal of TSPP and a change in the color of the solution from pink to blue. The DCIP in the system reacted with AA in a redox reaction to produce colorless phenol imine, the color of the solution changed from blue to green causing an obvious colorimetric response, and the TSPP/DCIP sensing system's fluorescence signal restored owing to AA introduced.
