Short-term choroidal changes as early indicators for future myopic shift in primary school children: results of a 2-year cohort study.

BACKGROUND: To assess predictive value of short-term choroidal changes for future myopic shift in children. METHODS: 577 eyes of 289 primary school children were prospectively followed for 2 years. Cycloplegic refractions at baseline, 1 year and 2 years, and choroidal measurements by optical coherence tomography at baseline and 3 months, were used for analyses. Myopic shift was defined as refraction change of at least -0.50 dioptre/year, at 2 years compared with baseline. RESULTS: 228 participants (455 eyes) completed 2-year follow-up. Approximately 37.6% of 311 initially non-myopic eyes and 73.6% of 144 initially myopic eyes developed a myopic shift. Notably, at 3 months greater reductions were found in initially myopic eyes with myopic shift, than in those without myopic shift-in choroidal thickness (ChT), luminal area (LA), stromal area (SA) and total choroidal area (TCA), but no significant differences in any choroidal parameters were observed between non-myopic eyes, with and without myopic shift. Multivariable analyses showed that in myopic eyes, each percentage increase in ChT, LA, SA and TCA was associated with reduced odds of myopic shift (all p<0.001). Similar associations were observed in non-myopic eyes, with smaller effects than in myopic eyes. Adding a 3-month percentage change of each choroidal parameter to a basic model including age, gender, parental myopia and baseline refraction significantly improved the predictive performance in myopic eyes (area under the receiver operating characteristic curves increasing from 0.650 to approximately 0.800, all p<0.05), but not in non-myopic eyes. CONCLUSION: Short-term choroidal changes could act as early indicators for future myopic shift in children.

Rational design of 2-benzylsulfinyl-benzoxazoles as potent and selective indoleamine 2,3-dioxygenase 1 inhibitors to combat inflammation.

Mimicking the transition state of tryptophan (Trp) and O2 in the enzymatic reaction is an effective approach to design indoleamine 2,3-dioxygenase 1 (IDO1) inhibitors. In this study, we firstly assembled a small library of 2-substituted benzo-fused five membered heterocycles and found 2-sulfinyl-benzoxazoles with interesting IDO1 inhibitory activities. Next the inhibitory activity toward IDO1 was gradually improved. Several benzoxazoles showed potent IDO1 inhibitory activity with IC50 of 82-91 nM, and exhibited selectivity between IDO1 and tryptophan 2,3-dioxygenase (TDO2). Enzyme binding studies showed that benzoxazoles are reversible type II IDO1 inhibitors, and modeling studies suggested that the oxygen atom of the sulfoxide in benzoxazoles interacts with the iron atom of the heme group, which mimics the transition state of Fe-O-O-Trp complex. Especially, 10b can effectively inhibit the NO production in lipopolysaccharides (LPS) stimulated RAW264.7 cells, and it also shows good anti-inflammation effect on mice acute inflammation model of croton oil induced ear edema.

Ultrahigh On/Off Ratio (110) Diamond Transistors with Exceptional Reproducibility of Normally Off Characteristics.

The development of monolithic integrated energy-efficient complementary circuits is crucial for the large-scale application of wide bandgap semiconductor-based high-frequency and high-power field-effect transistors (FETs). However, the inferior performance of p-channel FETs attributed to low hole density and mobility presents a substantial challenge. Diamond is a promising candidate due to its excellent comprehensive electrical properties and high thermal conductivity. Here, we report the fabrication of normally off diamond FETs based on a low work function metal gate and (110) hydrogen-terminated diamond with high hole density. The use of high-quality SiO2 layer ensures the complete depletion of the channel by the gate and offers high gating efficiency. Therefore, the developed devices demonstrate exceptional reproducibility of normally off characteristics with centrally distributed threshold voltages (-0.37 ± 0.3 V) and realize large current and voltage handling capabilities and low static standby power consumption in a synergic manner with record-high on/off ratio exceeding 1010, high current density (∼200 µA·µm-1), ultralow off-state current (∼fA·µm-1), and high breakdown voltage (-676 V). Additionally, the thermal desorption of negatively charged acceptors has been proven to significantly reduce carrier scattering. This work offers superior performance p-channel FETs for implementing energy-efficient complementary circuits, laying the groundwork for accelerated development in wide bandgap semiconductor power electronics.

Role of histone deacetylases and their inhibitors in neurological diseases.

Histone deacetylases (HDACs) are zinc-dependent deacetylases that remove acetyl groups from lysine residues of histones or form protein complexes with other proteins for transcriptional repression, changing chromatin structure tightness, and inhibiting gene expression. Recent in vivo and in vitro studies have amply demonstrated the critical role of HDACs in the cell biology of the nervous system during both physiological and pathological processes and have provided new insights into the conduct of research on neurological disease targets. In addition, in vitro and in vivo studies on HDAC inhibitors show promise for the treatment of various diseases. This review summarizes the regulatory mechanisms of HDAC and the important role of its downstream targets in nervous system diseases, and summarizes the therapeutic mechanisms and efficacy of HDAC inhibitors in various nervous system diseases. Additionally, the current pharmacological situation, problems, and developmental prospects of HDAC inhibitors are described. A better understanding of the pathogenic mechanisms of HDACs in the nervous system may reveal new targets for therapeutic interventions in diseases and help to relieve healthcare pressure through preventive measures.

Obesity-derived macrophages upregulate TNF-α to induce apoptosis in glial cell via the NF-κB/PHLPP1 axis.

Macrophages in obese adipose tissue have been shown to damage nerve fibers, however, the mechanism underlying how macrophages cause glial cell damage remains unknown. This study aimed to characterize the mechanism by which macrophages induce apoptosis in glial cell during obesity formation in mice by single-nucleus RNA sequencing (snRNA-seq). Cells obtained from paraepididymal adipose tissue in obese mice underwent snRNA-seq. Eighteen different clusters were identified, and 12 cell types were annotated, including glial cells, macrophages, and fibroblasts. There was a negative correlation between the number of glial cells and macrophages in mouse adipose tissue during the formation of obesity. The pro-apoptotic factor PHLPP1 was identified in GO Terms. The interaction between adipose tissue glial cells and macrophages was revealed via in-depth analysis, and the cell-cell communication mechanism between the TNF-α and NF-KB/PHLPP1 axes was perfected. Apoptosis of glial cell by upregulation of TNF-α via obesity-derived macrophages and activation of the NF-κB/PHLPP1 axis. We further revealed how macrophages induce apoptosis in glial cells during obesity formation, as well as different changes in the two cell populations. This study provides valuable resources and foundations for understanding the mechanistic effects of macrophages and glial cells during obesity formation, as well as diseases and potential interventions.

Synthesis of Multifunctional Organic Molecules via Michael Addition Reaction to Manage Perovskite Crystallization and Defect.

Additive engineering plays a pivotal role in achieving high-quality light-absorbing layers for high-performance and stable perovskite solar cells (PSCs). Various functional groups within the additives exert distinct regulatory effects on the perovskite layer. However, few additive molecules can synergistically fulfill the dual functions of regulating crystallization and passivating defects. Here, we custom-synthesized 2-ureido-4-pyrimidone (UPy) organic small molecules with diverse functional groups as additives to modulate crystallization and defects in perovskite films via the Michael addition reaction. Theoretical and experimental investigations demonstrate that the -OH groups in UPy exhibit significant effects in fixing uncoordinated Pb2+ ions, passivation of lead-iodide antisite defects, alleviating hysteresis, and reducing non-radiative recombination. Furthermore, the enhanced C=O and -NH2 motifs interact with the A-site cation via hydrogen bonding, which relieves residual strain and adjusts crystal orientation. This strategy effectively controls perovskite crystallization and passivates defects, ultimately enhancing the quality of perovskite films. Consequently, the open-circuit voltage of the UPy-based p-i-n PSCs reaches 1.20 V, and the fill factor surpasses 84%. The champion device delivers a power conversion efficiency of 25.75%. Remarkably, the unencapsulated device maintained 96.9% and 94.5% of its initial efficiency following 3,360 hours of dark storage and 1,866 hours of 1-sun illumination, respectively.

Pan-cancer bioinformatics analysis of hepatic leukemia factor and further validation in colorectal cancer.

Background: Hepatic leukemia factor (HLF) is associated with cancer onset, growth, and progression; however, little is known regarding its biological role in pan-cancer. In order to further evaluate the diagnostic and prognostic value of HLF in pan-cancer and colorectal cancer (CRC), we performed comprehensive bioinformatics analyses of the molecular mechanism of HLF in pan-cancer, with subsequent verification in CRC. Methods: We downloaded data (gene expression, clinical data, follow-up duration, and immune-related data) related to 33 solid tumor types from UCSC Xena (University of California Santa Cruz cancer database, https://xena.ucsc.edu/). HLF expression was analyzed in pan-cancer, and its diagnostic efficacy, prognostic value, and correlation with pathological stage and cancer immunity were determined. We also analyzed gene alterations in HLF and biological processes involved in its regulation in pan-cancer. Using CRC data in The Cancer Genome Atlas (TCGA), we assessed correlations between HLF and CRC diagnosis, prognosis, and drug sensitivity and performed functional enrichment analyses. Moreover, we constructed an HLF-related ceRNA regulatory network. Finally, we externally validated HLF expression and diagnostic and prognostic value in CRC using Gene Expression Omnibus (GEO) database, as well as by performing in vitro experiments. Results: HLF expression was downregulated in most tumors, and HLF showed good predictive potential for pan-cancer diagnosis and prognosis. It was closely related to the clinicopathological stages of pan-cancer. Further, HLF was associated with tumor microenvironment and immune cell infiltration in many tumors. Analyses involving cBioPortal revealed changes in HLF amplifications and mutations in most tumors. HLF was also closely associated with microsatellite instability and tumor mutational burden in pan-cancer and involved in regulating various tumor-related pathways and biological processes. In CRC, HLF expression was similarly downregulated, with implications for CRC diagnosis and prognosis. Functional enrichment analysis indicated the association of HLF with many cancer-related pathways. Further, HLF was associated with drug (e.g., oxaliplatin) sensitivity in CRC. The ceRNA regulatory network showed multigene regulation of HLF in CRC. External validation involving GEO databases and quantitative real-time polymerase chain reaction (qRT-PCR) data substantiated these findings. Conclusions: HLF expression generally exhibited downregulation in pan-cancer, contributing to tumor occurrence and development by regulating various biological processes and affecting tumor immune characteristics. HLF was also closely related to CRC occurrence and development. We believe HLF can serve as a reliable diagnostic, prognostic, and immune biomarker for pan-cancer.

Histone deacetylases and their inhibitors in inflammatory diseases.

Despite considerable research efforts, inflammatory diseases remain a heavy burden on human health, causing significant economic losses annually. Histone deacetylases (HDACs) play a significant role in regulating inflammation (via histone and non-histone protein deacetylation) and chromatin structure and gene expression regulation. Herein, we present a detailed description of the different HDACs and their functions and analyze the role of HDACs in inflammatory diseases, including pro-inflammatory cytokine production reduction, immune cell function modulation, and anti-inflammatory cell activity enhancement. Although HDAC inhibitors have shown broad inflammatory disease treatment potentials, their clinical applicability remains limited because of their non-specific effects, adverse effects, and drug resistance. With further research and insight, these inhibitors are expected to become important tools for the treatment of a wide range of inflammatory diseases. This review aims to explore the mechanisms and application prospects of HDACs and their inhibitors in multiple inflammatory diseases.

Impact of the triglyceride-glucose index on 28-day mortality in non-diabetic critically Ill patients with sepsis: a retrospective cohort analysis.

INTRODUCTION: Sepsis is a life-threatening condition that poses a globally high mortality rate. Identifying risk factors is crucial. Insulin resistance and the TYG index, associated with metabolic disorders, may play a role. This study explores their correlation with mortality in non-diabetic septic patients. METHODS: This retrospective cohort study used data from the MIMIC-IV (version 2.1) database, which includes over 50,000 ICU admissions from 2008 to 2019 at Beth Israel Deaconess Medical Center in Boston. We included adult patients with sepsis who were admitted to the intensive care unit in the study. The primary outcome was to evaluate the ability of TYG to predict death at 28-day of hospital admission in patients with sepsis. RESULTS: The study included 2213 patients with sepsis, among whom 549 (24.8%) died within 28 days of hospital admission. We observed a non-linear association between TYG and the risk of mortality. Compared to the reference group (lower TYG subgroup), the 28-day mortality increased in the higher TYG subgroup, with a fully adjusted hazard ratio of 2.68 (95% CI: 2.14 to 3.36). The area under the curve (AUC) for TYG was 67.7%, higher than for triglycerides alone (AUC = 64.1%), blood glucose (AUC = 62.4%), and GCS (AUC = 63.6%), and comparable to SOFA (AUC = 69.3%). The final subgroup analysis showed no significant interaction between TYG and each subgroup except for the COPD subgroup (interaction P-values: 0.076-0.548). CONCLUSION: In our study, TYG can be used as an independent predictor for all-cause mortality due to sepsis within 28 days of hospitalization.

Interferon Gamma Inducible Protein 30: from biological functions to potential therapeutic target in cancers.

Interferon Gamma Inducible Protein 30 (IFI30), also known as Gamma-Interferon-Inducible Lysosomal Thiol Reductase (GILT), is predominantly found in lysosomes and the cytoplasm. As the sole enzyme identified to catalyze disulfide bond reduction in the endocytic pathway, IFI30 contributes to both major histocompatibility complex (MHC) class I-restricted antigen cross-presentation and MHC class II-restricted antigen processing by decreasing the disulfide bonds of endocytosed proteins. Remarkably, emerging research has revealed that IFI30 is involved in tumorigenesis, tumor development, and the tumor immune response. Targeting IFI30 may provide new strategies for cancer therapy and improve the prognosis of patients. This review provided a comprehensive overview of the research progress on IFI30 in tumor progression, cellular redox status, autophagy, tumor immune response, and drug sensitivity, with a view to providing the theoretical basis for pharmacological intervention of IFI30 in tumor therapy, particularly in immunotherapy.

Co-CoSe heterogeneous fibers with strong interfacial built-in electric field as bifunctional electrocatalyst for high-performance Zn-air battery.

The explorations of efficient electrocatalysts to accelerate oxygen reactions in a wide temperature range is a crucial issue to the development of zinc-air batteries (ZAB) for all-climate applications. Herein, the Co-CoSe heterogeneous furry fibers (Co-CoSe@NHF) are developed as a bifunctional oxygen electrocatalyst for ZAB towards wide-temperature range applications. The Co-CoSe heterostructure with large work function difference (ΔWF) endows interfacial electron redistribution, which builds strong interfacial built-in electric field (BIEF) and improves the oxygen reactions. Meanwhile, the Co-CoSe heterostructure is encapsulated by in-situ grown carbon nanotubes, and forms the hollow fiber (NHF) with furry surface and beads-on-string configuration. The highly porous and conductive NHF configuration facilitates the fast kinetics and favors to accommodates volume change during cycling. As a result, the Co-CoSe@NHF achieves the superior bifunctional properties and good reliability for oxygen reactions. Integrated with the Co-CoSe@NHF fiber, the ZAB cell delivers the superior power density (301 mW cm-2) and long-term cycling stability over 280 h at 25 °C, and maintains the power densities of 126 mW cm-2 even the temperature decreases to -25 °C. Moreover, the solid-state ZAB exhibits significant flexibility and superior properties in a wide temperature range. Therefore, this work not only proposes a new strategy to design the high-performance bifunctional electrocatalysts, but also propels the development of flexible power sources for all-climate applications.

Single-cell tumor heterogeneity landscape of hepatocellular carcinoma: unraveling the pro-metastatic subtype and its interaction loop with fibroblasts.

BACKGROUND: Tumor heterogeneity presents a formidable challenge in understanding the mechanisms driving tumor progression and metastasis. The heterogeneity of hepatocellular carcinoma (HCC) in cellular level is not clear. METHODS: Integration analysis of single-cell RNA sequencing data and spatial transcriptomics data was performed. Multiple methods were applied to investigate the subtype of HCC tumor cells. The functional characteristics, translation factors, clinical implications and microenvironment associations of different subtypes of tumor cells were analyzed. The interaction of subtype and fibroblasts were analyzed. RESULTS: We established a heterogeneity landscape of HCC malignant cells by integrated 52 single-cell RNA sequencing data and 5 spatial transcriptomics data. We identified three subtypes in tumor cells, including ARG1+ metabolism subtype (Metab-subtype), TOP2A+ proliferation phenotype (Prol-phenotype), and S100A6+ pro-metastatic subtype (EMT-subtype). Enrichment analysis found that the three subtypes harbored different features, that is metabolism, proliferating, and epithelial-mesenchymal transition. Trajectory analysis revealed that both Metab-subtype and EMT-subtype originated from the Prol-phenotype. Translation factor analysis found that EMT-subtype showed exclusive activation of SMAD3 and TGF-ß signaling pathway. HCC dominated by EMT-subtype cells harbored an unfavorable prognosis and a deserted microenvironment. We uncovered a positive loop between tumor cells and fibroblasts mediated by SPP1-CD44 and CCN2/TGF-ß-TGFBR1 interaction pairs. Inhibiting CCN2 disrupted the loop, mitigated the transformation to EMT-subtype, and suppressed metastasis. CONCLUSION: By establishing a heterogeneity landscape of malignant cells, we identified a three-subtype classification in HCC. Among them, S100A6+ tumor cells play a crucial role in metastasis. Targeting the feedback loop between tumor cells and fibroblasts is a promising anti-metastatic strategy.

Cross-linking enhances the performance of four-electron carbonylpyridinium based polymers for lithium organic batteries.

Design and integration of multiple redox-active organic scaffolds into tailored polymer structures to enhance the specific capacity and cycling life is a long-term research goal. Inspired by nature, we designed and incorporated a 4-electron accepting dicarbonylpyridinium redox motif into linear (DBMP) and cross-linked polymer (TBMP) structures. Benefiting from the suppressed solubility and higher electronic conductivity, the cross-linked TBMP based electrode exhibits improved cycling stability and higher specific capacity than the linear counterpart. After 4000 cycles at 1 A g-1, TBMP can maintain a high capacity of 252 mA h g-1, surpassing the performance of many reported organic cathodes. The structural evolution and reaction kinetics during charge and discharge have been investigated in detail. This study demonstrates that cross-linking is an effective strategy to push the bio-derived carbonylpyridinium materials for high performance LOBs.

Synthesis and Biological Evaluation of Novel Psidium Meroterpenoid Derivatives against Cisplatin-Induced Acute Kidney Injury.

Cisplatin is a widely used drug for the clinical treatment of tumors. However, nephrotoxicity limits its widespread use. A series of compounds including eight analogs (G3-G10) and 40 simplifiers (G11-G50) were synthesized based on the total synthesis of Psiguamer A and B, which were novel meroterpenoids with unusual skeletons from the leaves of Psidium guajava. Among these compounds, (d)-G8 showed the strongest protective effect on cisplatin-induced acute kidney injury (AKI) in vitro and vivo, and slightly enhanced the antitumor efficacy of cisplatin. A mechanistic study showed that (d)-G8 promoted the efflux of cisplatin via upregulating the copper transporting efflux proteins ATP7A and ATP7B. It enhanced autophagy through the activation of the adenosine monophosphate-activated protein kinase (AMPK) signaling pathway. (d)-G8 showed no acute toxicity or apparent pathological damage in the healthy mice at a single dose of 1 g/kg. This study provides a promising lead against cisplatin-induced AKI.

On the FT-ICR mass spectrometry analysis of dissolved organic matter released by adsorbent during coal chemical wastewater treatment.

This study analyzed the dissolved organic matter (DOM) released by adsorbent during wastewater treatment. It was found that the adsorption method resulted in an organic removal efficiency of over 97 % for coal-to-olefin (CTO) wastewater, with the lowest value of 15.7 mg/L. The Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) detected 4111 DOM in the wastewater, 4052 remaining DOM after first-stage anthracite (ANC) adsorption, and 1013 after second-stage macroporous adsorption resin (MAR). The removal degree of lipids in wastewater was the highest, followed by aliphatic/amino-acid/mini-peptides and lignin. During the adsorption process, the proportion of halogenated compounds (HCs) declined from 59.86 % to 38.63 % and 21.67 %. Additionally, freshly produced 2035 and 311 DOMs were found in the adsorption effluent of ANC and MAR, respectively, with HCs accounting for 34.71 % and 67.96 %. Upon flowing ultra-pure water through ANC and MAR, the effluent dissolved organic carbon (DOC) ranges were 1.118-3.574 mg/L and 1.014-2.557 mg/L, respectively. There were 159 and 131 species of DOM detected, respectively, with HCs content of 59.06 % and 45.02 %. Comparative experiments revealed the complex components of the wastewater promoting the release of organic matter on the adsorbent surface that further reacted to generate organic matter. However, fewer substances were released by the adsorbent.

Factors associated with pathological complete remission after neoadjuvant chemoradiotherapy in locally advanced rectal cancer: a real-world clinical setting.

Objective: This study aims to identify factors associated with achieving a pathological complete remission (pCR) in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (nCRT). Methods: We conducted a cohort analysis of 171 LARC patients who underwent curative resection post-nCRT at the First Affiliated Hospital of Guangxi Medical University between January 2015 and December 2021. The data encompassed clinical and pathological information. Univariate and binary logistic regression multivariate analyses were employed to examine the factors influencing pCR achievement after nCRT. Kappa value tests were utilized to compare clinical staging after nCRT with postoperative pathological staging. Results: Postoperative histopathology revealed that of the 171 patients, 40 (23.4%) achieved TRG 0 grade (pCR group), while 131 (76.6%) did not achieve pCR, comprising 36 TRG1, 42 TRG2, and 53 TRG3 cases. Univariate analysis indicated that younger age (p=0.008), reduced tumor occupation of intestinal circumference (p =0.008), specific pathological types (p=0.011), and lower pre-nCRT CEA levels (p=0.003) correlated with pCR attainment. Multivariate analysis identified these factors as independent predictors of pCR: younger age (OR=0.946, p=0.004), smaller tumor occupation of intestinal circumference (OR=2.809, p=0.046), non-mucinous adenocarcinoma pathological type (OR=10.405, p=0.029), and lower pre-nCRT serum CEA levels (OR=2.463, p=0.031). Clinical re-staging post-nCRT compared to postoperative pathological staging showed inconsistent MRI T staging (Kappa=0.012, p=0.718, consistency rate: 35.1%) and marginally consistent MRI N staging (Kappa=0.205, p=0.001, consistency rate: 59.6%). Conclusion: LARC patients with younger age, presenting with smaller tumor circumferences in the intestinal lumen, lower pre-nCRT serum CEA levels, and non-mucinous adenocarcinoma are more likely to achieve pCR after nCRT. The study highlights the need for improved accuracy in clinical re-staging assessments after nCRT in LARC.

High-Performance Intrinsically Stretchable Organic Photovoltaics Enabled by Robust Silver Nanowires/S-PH1000 Hybrid Transparent Electrodes.

Intrinsically stretchable organic photovoltaics (is-OPVs) hold significant promise for integration into self-powered wearable electronics. However, their potential is hindered by the lack of sufficient consistency between optoelectronic and mechanical properties. This is primarily due to the limited availability of stretchable transparent electrodes (STEs) that possess both high conductivity and stretchability. Here, a hybrid STE with exceptional conductivity, stretchability, and thermal stability is presented. Specifically, STEs are composed of the modified PH1000 (referred to as S-PH1000) and silver nanowires (AgNWs). The S-PH1000 endows the STE with good stretchability and smoothens the surface, while the AgNWs enhance the charge transport. The resulting hybrid STEs enable is-OPVs to a remarkable power conversion efficiency (PCE) of 16.32%, positioning them among the top-performing is-OPVs. With 10% elastomer, the devices retain 82% of the initial PCE after 500 cycles at 20% strain. Additionally, OPVs equipped with these STEs exhibit superior thermal stability compared to those using indium tin oxide electrodes, maintaining 75% of the initial PCE after annealing at 85 °C for 390 h. The findings underscore the suitability of the designed hybrid electrodes for efficient and stable is-OPVs, offering a promising avenue for the future application of OPVs.

Bintrafusp Alfa for Recurrent or Metastatic Cervical Cancer After Platinum Failure: A Nonrandomized Controlled Trial.

Importance: Cervical cancer is a common and lethal cancer worldwide. Bintrafusp alfa is a first-in-class bifunctional fusion protein composed of the extracellular domain of the human transforming growth factor ß receptor II (or transforming growth factor ß trap) fused via a flexible linker to the C-terminus of each heavy chain of an immunoglobulin G1 antibody blocking programmed cell death 1 ligand 1. Objective: To evaluate the safety and response rates of bintrafusp alfa in patients with recurrent or metastatic cervical cancer. Design, Setting, and Participants: This phase 2 nonrandomized controlled trial evaluated bintrafusp alfa monotherapy in patients with recurrent or metastatic cervical cancer with disease progression during or after platinum-based chemotherapy. Data were collected from March 2020 to February 2022. Intervention: Patients received bintrafusp alfa, 1200 mg, intravenously once every 2 weeks. Main Outcomes and Measures: The primary end point was confirmed objective response rate per Response Evaluation Criteria in Solid Tumors version 1.1 by an independent review committee. Results: At data cutoff, 146 of 203 screened patients received 1 or more doses of bintrafusp alfa; of these, the median (range) age was 53 (24-79) years. The study met its primary end point of a 95% CI above the objective response rate benchmark of 15%, with a confirmed objective response rate of 21.9% (95% CI, 15.5-29.5) per the independent review committee. Of these patients, 19 (59.4%) had a durable response of 6 months or more. At data cutoff, responses were ongoing in 13 of 32 responders (40.6%). The most common treatment-related adverse events were anemia (25 [17.1%]), rash (21 [14.4%]), hypothyroidism (15 [10.3%]), and pruritus (15 [10.3%]). Any-cause adverse events of special interest included anemia (82[56.2%]), bleeding events (81 [55.5%]), and immune-related adverse events (49 [33.6%]). Conclusions and Relevance: This phase 2 nonrandomized controlled trial of bintrafusp alfa met its primary end point, which may support the potential of a bispecific therapy targeting transforming growth factor ß and programmed cell death 1 ligand 1 in patients with recurrent or metastatic cervical cancer. Trial Registration: ClinicalTrials.gov Identifier: NCT04246489.

Sodium alginate-based high conductive, ultra-stretchable hydrogel fibers for electrolytes of flexible solid-state supercapacitors.

The flexibility and safety of energy storage systems are crucial, and hydrogels as one of the most promising candidates for solid-state electrolytes. We present a conductive hydrogel based on sodium alginate that exhibits ultra-stretchable (4200 %) and high conductivity (16.3 S m-1). The mechanical properties of the conductive hydrogel are achieved by optimizing the topology of the sodium alginate and harnessing the synergistic effect of non-covalent interaction among different components. And a conductive structure within hydrogels was successfully established through the synergistic combination of ion and metal nanoparticles. The flexible supercapacitor (FSC) with conductive hydrogel as solid electrolytes demonstrated an area-specific capacitance of up to 274.28 mF cm-2 at a current density of 1 mA cm-2. And the energy density of the FSC is as high as 187 µWh cm-2 at a power density of 1.2 mW cm-2. The voltage range of the FSC is also extended to 1.4 V. The FSC also exhibited exceptional flexibility and stability, including insensitivity to bending angles and remarkable cycle durability (82.4 % after 10,000 cycles). The study presents a novel design for the development of solid-state electrolytes, with the aim of creating a new generation of FSC that exhibit superior safety and high energy density.
