    Abstract: A novel sextuple hydrogen‐bonding (HB) self‐assembly molecular duplex bearing red‐emitting perylene diimide (PDI) fluorophores, namely PDIHB , was synthesized, and its molecular structure was confirmed by 1 H NMR, 13 C NMR, TOF‐MS and 2D NMR. Compared with the small molecular reference compound PDI , PDIHB shows one time enhanced fluorescence efficiency in solid state (4.1% vs. 2.1%). More importantly, the presence of bulky HB oligoamide strands in PDIHB could trigger effective spatial separation between guest and host fluorophores in thin solid film state, hence inefficient energy transfer occurs between the blue‐emitting host 2TPhNIHB and red guest PDIHB in the 2 wt% guest/host blending film. As a result, a solution‐processed organic light‐emitting diode (OLED) with quite simple device structure of ITO/PEDOT:PSS (40 nm)/PVK (40 nm)/ PDIHB (2 wt%): 2TPhNIHB (50 nm)/LiF (0.8 nm)/Al (100 nm) could emit bias‐independent warm‐white electroluminescence with stable Commission Internationale de L'Eclairage coordinates of (0.42, 0.33), and the maximum brightness and current efficiency of this device are 260 cd·m −2 and 0.49 cd·A −1 , respectively. All these results indicated that HB self‐assembly supramolecular fluorophores could act as prospective materials for white OLED application.

    Abstract: Exciton dynamics is one of the core issues lies in the field of achieving high efficiency organic light‐emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) molecules. The authors briefly review the host dependence of TADF dopant, and then discuess the host—guest interaction in TADF OLEDs. By the means of transient electroluminescence measurement, the dynamics of triplet and singlet excitons are studied. Results show that host material with high T1 energy levels, large spectral overlap with TADF dopant's absorption and free of exciplex formation exhibits higher TADF character. Furthermore, the underlying reason for the efficiency roll‐off of the TADF OLEDs is clarified to be attributed to deeply trapped charges.

    Abstract: The clinical features have been well described in obese chronic hepatitis B (CHB) patients with nonalcoholic fatty liver disease (NAFLD). However, little is known about the clinical features of lean CHB‐NAFLD patients. Methods The study retrospectively included treatment‐naïve CHB patients who underwent ultrasound between 2015 and 2021. Liver fibrosis was assessed by aspartate aminotransferase (AST) to platelet ratio index (APRI), Fibrosis‐4 score (FIB‐4), NAFLD fibrosis score (NFS), and transient elastography. Results Among 1226 CHB‐NAFLD patients, 25.0% patients were lean. The age, gender, and platelet, alanine aminotransferase, AST, and albumin levels were comparable between lean CHB‐NAFLD and nonlean patients. The levels of plasma glucose, triglycerides, total cholesterol, and uric acid, as well as proportions of concurrent hypertension and diabetes, were lower in lean patients. Lean patients presented higher hepatitis B surface antigen (HBsAg) levels (3.4 log 10 IU/ml vs. 3.2 log 10 IU/ml, p  = 0.006), hepatitis B virus (HBV) DNA levels (4.1 log 10 IU/ml vs. 3.2 log 10 IU/ml, p   〈  0.001), and hepatitis B e antigen (HBeAg) positive proportions (40.4% vs. 30.2%, p  = 0.002) than nonlean patients. The values of APRI, FIB‐4, and liver stiffness were comparable between two groups. However, lean patients had lower NFS values (−3.0 vs. −2.6, p   〈  0.001) and lower proportions (12.6% vs. 21.1%, p  = 0.003) of advanced fibrosis (NFS ≥ −1.5) than nonlean patients. Similar results were observed in HBeAg‐positive and HBeAg‐negative subgroups. Conclusions Nearly a quarter of CHB‐NAFLD patients were lean. Lean patients had lower proportions of metabolic abnormalities and advanced liver fibrosis than nonlean patients. However, lean CHB‐NAFLD patients had higher HBsAg levels, HBV DNA levels, and HBeAg‐positive proportions. Registry and registration no. of the study/trial: Clinicaltrials.gov, Identifier: NCT03097952.

    Abstract: A simple azulene‐containing squaraine dye ( AzUSQ ) showing bandgap of 1.38 eV and hole mobility up to 1.25×10 −4  cm 2  V −1  s −1 was synthesized. With its low bandgap, an organic photovoltaic (OPV) device based on it has been made that exhibits an impressive open‐circuit voltages ( V oc ) of 0.80 V. Hence, azulene might be a promising structural unit to construct OPV materials with simultaneous low bandgap, high hole mobility and high V oc .

    Intratumoral CD103 + CD8 + T cells predict response to neoadjuvant chemoimmunotherapy in advanced head and neck squamous cell carcinoma
    Wiley ; 2023
    In:  Cancer Communications
    Details
    In: Cancer Communications, Wiley
    Abstract: Immune cell heterogenicity is known to determine the therapeutic response to cancer progression. Neoadjuvant chemoimmunotherapy (NACI) has shown clinical benefits in some patients with advanced head and neck squamous cell carcinoma (HNSCC), but the underlying mechanism behind this clinical response is unknown. The efficacy of NACI needs to be potentiated by identifying accurate biomarkers to predict clinical responses. Here, we attempted to identify molecules predicting NACI response in advanced HNSCC. Methods We performed combined single‐cell RNA sequencing (scRNA‐seq) and multiplex immunofluorescence (mIHC) staining with tumor samples derived from NACI‐treated HNSCC patients to identify a new tumor‐infiltrating cell (TIL) subtype, CD103 + CD8 + TILs, associated with clinical response, while both in vitro and in vivo assays were carried out to determine its antitumor efficiency. The regulatory mechanism of the CD103 + CD8 + TILs population was examined by performing cell‐cell interaction analysis of the scRNA‐seq data and spatial analysis of the mIHC images. Results We established intratumoral CD103 + CD8 + TILs density as a determinant of NACI efficacy in cancers. Our scRNA‐seq results indicated that the population of CD103 + CD8 + TILs was dramatically increased in the responders of NACI‐treated HNSCC patients, while mIHC analysis confirmed the correlation between intratumoral CD103 + CD8 + TILs density and NACI efficacy in HNSCC patients. Further receiver operating characteristic curve analysis defined this TIL subset as a potent marker to predict patient response to NACI. Functional assays showed that CD103 + CD8 + TILs were tumor‐reactive T cells, while programmed cell death protein‐1 (PD‐1) blockade enhanced CD103 + CD8 + TILs cytotoxicity against tumor growth in vivo. Mechanistically, targeting the triggering receptor expressed on myeloid cells 2‐positive (TREM2 + ) macrophages might enhance the population of CD103 + CD8 + TILs and facilitate antitumor immunity during NACI treatment. Conclusions Our study highlights the impact of intratumoral CD103 + CD8 + TILs density on NACI efficacy in different cancers, while the efforts to elevate its population warrant further clinical investigation.

    Abstract: Buccal mucosa cancer (BMC) is one of the most common oral cancers and has poor prognosis. The study aimed to develop and validate nomograms for predicting the 1‐, 3‐, and 5‐year overall survival (OS) and cancer‐specific survival (CSS) of BMC patients. Methods We collected and reviewed information on BMC patients diagnosed between 2004 and 2019 from the Surveillance Epidemiology and End Results database. Two nomograms were developed and validated to predict the OS and CSS based on predictors identified by univariate and multivariate Cox regression. An extra external validation was further performed using data from Sun Yat‐sen Memorial Hospital (SYSMH). Results A total of 3154 BMC patients included in this study were randomly assigned to training and validation groups in a 2:1 ratio. Independent prognostic predictors were identified, confirmed, and fitted into nomograms for OS and CSS, respectively. The C‐indices are 0.767 (Training group OS), 0.801 (Training group CSS), 0.763 (Validation group OS), and 0.781 (Validation group OS), respectively. Moreover, the nomograms exhibited remarkable precision in forecasting and significant clinical significance, as evidenced by receiver operating characteristic (ROC) curves, calibration curves, and decision curve analyses (DCA). The final validation using our data from SYSMH also showed high accuracy and substantial clinical benefits within the nomograms. The C‐indices are 0.849 (SYSMH group OS) and 0.916 (SYSMH group CSS). These indexes are better than tumor, node, and metastasis stage based on prediction results. Conclusions The nomograms developed with great performance predicted 1‐, 3‐, and 5‐year OS and CSS of BMC patients. Use of the nomograms in clinical practices shall bring significant benefits to BMC patients.

    Bacteria‐Derived Outer‐Membrane Vesicles Hitchhike Neutrophils to Enhance Ischemic Stroke Therapy

    Abstract: The treatment of reperfusion injury after ischemic stroke remains unsatisfactory since the blood‐brain barrier (BBB) prevents most neuroprotective agents from entering the brain. Here, a strategy is proposed based on bacteria‐derived outer‐membrane vesicle (OMV) hitchhiking on the neutrophils for enhanced brain delivery of pioglitazone (PGZ) to treat ischemic stroke. By encapsulating PGZ into OMV, the resulting OMV@PGZ nanoparticles inherit the functions associated with the bacterial outer membrane, making them ideal decoys for neutrophil uptake. The results show that OMV@PGZ simultaneously inhibits the activation of nucleotide oligomerization‐like receptor protein 3 (NLRP3) inflammasomes and ferroptosis and reduces the reperfusion injury to exert a neuroprotective effect. Notably, the transcription factors Pou2f1 and Nrf1 of oligodendrocytes are identified for the first time to be involved in this process and promoted neural repair by single‐nucleus RNA sequencing (snRNA‐seq).

    Abstract: Superlattices are attracting extensive attention due to their unique properties. Nevertheless, the observations of superlattices are limited to those layered structures with weak interlayered interactions, and the effect of the superlattice in metal‐based nanostructures on catalysis is unexplored yet. We here report a facile wet‐chemical method for synthesizing two‐dimensional Ru multilayered nanosheets (Ru MNSs) with a superlattice. Characterizations reveal that the superlattice is formed by stacking Ru layers with twisted angles from 2° to 30°. Owing to the strong synergy between the adjacent layers, Ru MNSs can serve as an efficient catalyst for the alkaline hydrogen evolution reaction (HER). Theoretical calculations reveal that the superlattice can induce the strain effect, which leads to lattice contraction and weak *H adsorption ability, as a result of improved HER performance. This work sheds new light on the utilization of the superlattice on enhancing catalysis in metal‐based materials.

    Abstract: Alternative low‐temperature solution‐processed hole‐transporting materials (HTMs) without dopant are critical for highly efficient perovskite solar cells (PSCs). Here, two novel small molecule HTMs with linear π‐conjugated structure, 4,4′‐bis(4‐(di‐ p ‐toyl)aminostyryl)biphenyl (TPASBP) and 1,4′‐bis(4‐(di‐ p ‐toyl)aminostyryl)benzene (TPASB), are applied as hole‐transporting layer (HTL) by low‐temperature (sub‐100 °C) solution‐processed method in p‐i‐n PSCs. Compared with standard poly(3,4‐ethylenedioxythiophene): poly(styrenesulfonic acid) (PEDOT:PSS) HTL, both TPASBP and TPASB HTLs can promote the growth of perovskite (CH 3 NH 3 PbI 3 ) film consisting of large grains and less grain boundaries. Furthermore, the hole extraction at HTL/CH 3 NH 3 PbI 3 interface and the hole transport in HTL are also more efficient under the conditions of using TPASBP or TPASB as HTL. Hence, the photovoltaic performance of the PSCs is dramatically enhanced, leading to the high efficiencies of 17.4% and 17.6% for the PSCs using TPASBP and TPASB as HTL, respectively, which are ≈40% higher than that of the standard PSC using PEDOT:PSS HTL.
