Lithium-Ion Conductive Coatings for Nickel-Rich Cathodes for Lithium-Ion Batteries.

Nickel (Ni)-rich cathodes are among the most promising cathode materials of lithium batteries, ascribed to their high-power density, cost-effectiveness, and eco-friendliness, having extensive applications from portable electronics to electric vehicles and national grids. They can boost the wide implementation of renewable energies and thereby contribute to carbon neutrality and achieving sustainable prosperity in the modern society. Nevertheless, these cathodes suffer from significant technical challenges, leading to poor cycling performance and safety risks. The underlying mechanisms are residual lithium compounds, uncontrolled lithium/nickel cation mixing, severe interface reactions, irreversible phase transition, anisotropic internal stress, and microcracking. Notably, they have become more serious with increasing Ni content and have been impeding the widespread commercial applications of Ni-rich cathodes. Various strategies have been developed to tackle these issues, such as elemental doping, adding electrolyte additives, and surface coating. Surface coating has been a facile and effective route and has been investigated widely among them. Of numerous surface coating materials, have recently emerged as highly attractive options due to their high lithium-ion conductivity. In this review, a thorough and comprehensive review of lithium-ion conductive coatings (LCCs) are made, aimed at probing their underlying mechanisms for improved cell performance and stimulating new research efforts.

Interface Modifications of Lithium Metal Anode for Lithium Metal Batteries.

Lithium metal batteries (LMBs) enable much higher energy density than lithium-ion batteries (LIBs) and thus hold great promise for future transportation electrification. However, the adoption of lithium metal (Li) as an anode poses serious concerns about cell safety and performance, which has been hindering LMBs from commercialization. To this end, extensive effort has been invested in understanding the underlying mechanisms theoretically and experimentally and developing technical solutions. In this review, we devote to providing a comprehensive review of the challenges, characterizations, and interfacial engineering of Li anodes in both liquid and solid LMBs. We expect that this work will stimulate new efforts and help peer researchers find new solutions for the commercialization of LMBs.

Quantitative evaluation of disc degeneration using dual-energy CT: advantages of R-VH, D-VH values and the IVNCa + CT model.

OBJECTIVE: To evaluate the correlation between dual-energy CT (DECT) virtual calcium free (VNCA), CT attenuation, the ratio and difference of VNCA to CT attenuation, and Pfirrmann grading of lumbar disc degeneration. METHODS: A retrospective analysis on 135 intervertebral discs from 30 patients who underwent DECT and MR. Discs was graded using the Pfirrmann system. ROIs on the sagittal plane assessed HU value, VNCA value, Rho value, Z value, R-VH value, and D-VH value. Correlation, grade differences, and multivariate regression models were assessed. Diagnostic performance and cut-off values were determined using AUC. RESULTS: VNCA (r = 0.589, P < 0.001), R-VH (r = 0.622, P < 0.001), and D-VH (r = 0.613, P < 0.001) moderately correlated with Pfirrmann grading. HU (r = 0.388, P < 0.001), Rho (r = 0.142, P = 0.102), and Z (r = -0.125, P = 0.153) showed a weak correlation. R-VH, D-VH, and VNCA had significantly higher correlation than HU. Statistically significant differences were observed in P values of VNCA, HU, R-VH, and D-VH in relative groups (P < 0.05), but not in Rho and Z values (P > 0.05). R-VH and D-VH had significant differences between Pfirrmann grades 1 and 2, and grades 2 and 3 (early stage) (P < 0.05). AUC readings of R-VH and D-VH (≥2, ≥3, ≥4) were higher. The multivariate model IVNCa + CT had the highest AUC. CONCLUSION: The new quantitative indices R-VH value and D-VH value of DECT have advantages over VNCA value and HU value in evaluating early-stage disc degeneration (≥2 grades, ≥3 grades). The multivariate model IVNCa + CT has the best AUC values for evaluating disc degeneration at all stages.

Antiviral Effect of Extracellular Matrix Protein ABI3BP on Vesicular Stomatitis Virus and Its Mechanism: A Preliminary Study In Vitro.

Objective To explore the influence of extracellular matrix protein ABI-interactor 3-binding protein (ABI3BP) on vesicular stomatitis virus (VSV) genome replication and innate immune signaling pathway.Methods The small interfering RNA (siRNA) was transfected to knock down ABI3BP gene in human skin fibroblast BJ-5ta cells. VSV-green fluorescent protein (VSV-GFP)-infected cell model was established. The morphological changes and F-actin stress fiber formation were detected on ABI3BP knockdown cells by phalloidin immunofluorescence staining. The mRNA level of virus replication was detected by RT-qPCR in BJ-5ta cells after VSV-GFP infection; western blotting was performed to detect the changes in interferon regulatory factor 3 (IRF3) and TANK-binding kinase 1 (TBK1) phosphorylation levels.Results The VSV-GFP-infected BJ-5ta cell model was successfully established. Efficient knockdown of ABI3BP in BJ-5ta cells was achieved. Phalloidin immunofluorescence staining revealed structural rearrangement of intracellular F-actin after ABI3BP gene knockdown. Compared with the control group, the gene copy number of VSV-GFP in ABI3BP knockdown cells increased by 2.2 - 3.5 times (P<0.01) and 2.2 - 4.0 times (P<0.01) respectively when infected with VSV of multiplicity of infection 0.1 and 1. The expression of viral protein significantly increased in ABI3BP knockdown cells after virus infection. The activation of type-I interferon pathway, as determined by phosphorylated IRF3 and phosphorylated TBK1, was significantly decreased in ABI3BP knockdown cells after VSV-GFP infection.Conclusions Extracellular matrix protein ABI3BP plays an important role in maintaining the formation and rearrangement of actin structure. ABI3BP gene deletion promotes RNA virus replication, and ABI3BP is an important molecule that maintains the integrity of type I interferon pathway.

Effects of cathode loadings and anode protection on the performance of lithium metal batteries.

While lithium-ion batteries (LIBs) are approaching their energy limits, lithium metal batteries (LMBs) are undergoing intensive investigation for higher energy density. Coupling LiNi0.8Mn0.1Co0.1O2(NMC811) cathode with lithium (Li) metal anode, the resultant Li||NMC811 LMBs are among the most promising technologies for future transportation electrification, which have the potential to realize an energy density two times higher than that of state-of-the-art LIBs. To maximize their energy density, the Li||NMC811 LMBs are preferred to have their cathode loading as high as possible while their Li anode as thin as possible. To this end, we investigated the effects of different cathode active material loadings (2-14 mg cm-2) on the performance of the Li||NMC811 LMBs. Our study revealed that the cathode loadings have remarkably affected the cell performance, in terms of capacity retention and sustainable capacity. Cells with high cathode loadings are more liable to fade in capacity, due to more severe formation of the CEI and more sluggish ion transport. In this study, we also verified that the protection of the Li anode is significant for achieving better cell performance. In this regard, our newly developed Li-containing glycerol (LiGL) via molecular layer deposition (MLD) is promising to help boost the cell performance, which was controllably deposited on the Li anode.

The cyclic guanosine monophosphate synthase-stimulator of interferon genes pathway as a potential target for tumor immunotherapy.

Cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) synthase (cGAS) detects infections or tissue damage by binding to microbial or self-DNA in the cytoplasm. Upon binding DNA, cGAS produces cGAMP that binds to and activates the adaptor protein stimulator of interferon genes (STING), which then activates the kinases IKK and TBK1 to induce the secretion of interferons and other cytokines. Recently, a series of studies demonstrated that the cGAS-STING pathway, a vital component of host innate immunity, might play an important role in anticancer immunity, though its mechanism remains to be elucidated. In this review, we highlight the latest understanding of the cGAS-STING pathway in tumor development and the advances in combination therapy of STING agonists and immunotherapy.

EDC-DTI: An end-to-end deep collaborative learning model based on multiple information for drug-target interactions prediction.

Innovations in drug-target interactions (DTIs) prediction accelerate the progression of drug development. The introduction of deep learning models has a dramatic impact on DTIs prediction, with a distinct influence on saving time and money in drug discovery. This study develops an end-to-end deep collaborative learning model for DTIs prediction, called EDC-DTI, to identify new targets for existing drugs based on multiple drug-target-related information including homogeneous information and heterogeneous information by the way of deep learning. Our end-to-end model is composed of a feature builder and a classifier. Feature builder consists of two collaborative feature construction algorithms that extract the molecular properties and the topology property of networks, and the classifier consists of a feature encoder and a feature decoder which are designed for feature integration and DTIs prediction, respectively. The feature encoder, mainly based on the improved graph attention network, incorporates heterogeneous information into drug features and target features separately. The feature decoder is composed of multiple neural networks for predictions. Compared with six popular baseline models, EDC-DTI achieves highest predictive performance in the case of low computational costs. Robustness tests demonstrate that EDC-DTI is able to maintain strong predictive performance on sparse datasets. As well, we use the model to predict the most likely targets to interact with Simvastatin (DB00641), Nifedipine (DB01115) and Afatinib (DB08916) as examples. Results show that most of the predictions can be confirmed by literature with clear evidence.

Chinese herbal injections plus Western Medicine on inflammatory factors for patients with acute exacerbation of chronic obstructive pulmonary disease: a systematic review and network meta-analysis.

Background: Chinese herbal injections (CHIs) are commonly prescribed in China as adjuvant therapy for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, evidence supporting the effect of CHIs on inflammatory factors for patients with AECOPD is insufficient, posing a challenge for clinicians to choose the optimal CHIs for AECOPD. This network meta-analysis (NMA) aimed to compare the effectiveness of several CHIs combined with Western Medicine (WM) and WM alone on the inflammatory factors in AECOPD. Methods: Randomized controlled trials (RCTs) on different CHIs for treating AECOPD were thoroughly searched from several electronic databases up to August 2022. The quality assessment of the included RCTs was conducted according to the Cochrane risk of bias tool. Bayesian network meta-analyses were designed to assess the effectiveness of different CHIs. Systematic Review Registration CRD42022323996. Results: A total of 94 eligible RCTs involving 7,948 patients were enrolled in this study. The NMA results showed that using Xuebijing (XBJ), Reduning (RDN), Tanreqing (TRQ), and Xiyanping (XYP) injections combined with WM significantly improved treatment effects compared to using WM alone. XBJ + WM and TRQ + WM significantly changed the level of C-reactive protein (CRP), white blood cells, percentage of neutrophils, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). TRQ + WM showed the most significant effect in reducing the level of procalcitonin. XYP + WM and RDN + WM could reduce the level of white blood cells and the percentage of neutrophils. A total of 12 studies reported adverse reactions in detail, and 19 studies demonstrated no significant adverse reactions. Conclusions: This NMA showed that using CHIs combined with WM could significantly reduce the level of inflammatory factors in AECOPD. A combination of TRQ and WM may be a relatively prior adjuvant therapy option for AECOPD treatment considering its effects in reducing the levels of the anti-inflammatory mediators.

Efficacy and safety of proton pump inhibitors and H2 receptor antagonists in the initial non­eradication treatment of duodenal ulcer: A network meta­analysis.

The present network meta-analysis aimed to enhance the corresponding evidence with respect to the efficacy and safety of pharmaceuticals treatments. Frequentist network meta-analysis was used. Medical literature up to November 2022 was searched for randomized clinical trials assessing the efficacy and safety of these pharmaceuticals, either compared with each other or compared with placebo. With the exception of ranitidine (300 mg four times daily) and vonoprazan (20 mg once daily) having lower safety than placebo, the efficacy and safety of the remaining treatments were superior to placebo. Cimetidine (400 mg four times daily) and pantoprazole (40 mg once daily) were ranked first in terms of efficacy. The frequentist network meta-analysis shows that for cimetidine (except 400 mg once daily), famotidine, rabeprazole, ilaprazole, lansoprazole (except 7.5 mg once daily) and omeprazole (except 10 mg once daily or 30 mg once daily), the efficacy comparison between the different doses of each of the aforementioned pharmaceuticals did not indicate statistically significant differences. In conclusion, pantoprazole (40 mg once daily) was the best choice for the initial non-eradication treatment of patients with duodenal ulcer, and cimetidine (400 mg twice daily), omeprazole (20 mg once daily), lansoprazole (15 mg once daily), ilaprazole (5 mg once daily) and rabeprazole (10 mg once daily) could be used as the first choice. If the aforementioned pharmaceuticals cannot be prescribed, famotidine (40 mg twice daily) is recommended.

Persistent Lipid Accumulation Leads to Persistent Exacerbation of Endoplasmic Reticulum Stress and Inflammation in Progressive NASH via the IRE1α/TRAF2 Complex.

Non-alcoholic steatohepatitis (NASH) is a metabolic disorder that often leads to other severe liver diseases, yet treatment options are limited. Endoplasmic reticulum (ER) stress is an important pathogenetic mechanism of NASH and plays a key role in tandem steatosis as well as liver inflammation. This study aims to develop a progressive NASH model through sustained lipid accumulation and to elucidate its molecular mechanism through IRE1α/TRAF2 complex. Male SD rats were fed a high-fat diet (HFD) for 4, 8, and 12 weeks to induce progressive NASH. MRNA sequencing and PPI analysis were used to screen core genes. Transmission electron microscopy, immunofluorescence staining, ELISA, qRT-PCR, and Western blotting were used at each time point to compare differences between each index of progressive NASH at 4, 8, and 12 weeks. Sustained lipid accumulation led to structural disruption of the ER, a reduction in ER number, and an increase of lipid droplet aggregation in hepatocytes. Persistent lipid accumulation led to a persistent increase in mRNA and protein expression of the IRE1α/TRAF2 complex, IKK/IκB/NF-κB signaling pathway and ASK1/JNK1 signaling pathway, and TNF-α, IL-1ß, and IL-6 also continued to increase. Persistent lipid accumulation led to a persistent exacerbation of ER stress and inflammation in progressive NASH via the IRE1α/TRAF2 complex.

BACKGROUND: Meta-analysis was used to evaluate the efficacy of Fufang Biejia Ruangan Tablets in the treatment of chronic hepatitis B (CHB) liver fibrosis. METHODS: Databases, including PubMed, China Knowledge Network (CNKI), China Biomedical Database (CBM), Wan Fang, VIP database, Embase, and Cochrane Library were searched. The time was searched up to May 2022. The participant intervention comparator outcomes of this study were as follows: P, patients with CHB liver fibrosis; I, Fufang Biejia Ruangan Tablets; C, pharmacological placebo; O, the efficacy rate, alanine transaminase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumin (ALB), procollagen III protein (PIIIP), hyaluronic acid (HA), laminin (LN), collagen C type IV (IV-C), portal vein diameter, spleen thickness and HBV-DNA negative conversion rate. The Cochrane Risk of Bias tool, Begg's test and Egger's test were used to evaluate the methodological quality of eligible studies. A randomized controlled trial of Fufang Biejia Ruangan Tablets was used to treat CHB liver fibrosis. Three reviewers independently selected trials, extracted data, cross-checked, and performed methodological quality assessments. Data analysis was completed by Review Manager 5.3. RESULTS: Twenty-six studies with 2717 patients were included in the meta-analysis. The meta-analysis showed that Fufang Biejia Ruangan Tablets was effective by increasing the efficacy. Fufang Biejia Ruangan Tablets was more efficient in improving ALT, AST, TBIL, ALB, PIIIP, HA, LN, IV-C, portal vein diameter, spleen thickness, and HBV-DNA negative conversion rate with no serious adverse reactions. CONCLUSION: It was shown that Fufang Biejia Ruangan Tablets can effectively improve liver function and relieve liver fibrosis, but future research should focus on rigorously designed, multicenter, and large randomized controlled trials.

Atomic and Molecular Layer Deposition as Surface Engineering Techniques for Emerging Alkali Metal Rechargeable Batteries.

Alkali metals (lithium, sodium, and potassium) are promising as anodes in emerging rechargeable batteries, ascribed to their high capacity or abundance. Two commonly experienced issues, however, have hindered them from commercialization: the dendritic growth of alkali metals during plating and the formation of solid electrolyte interphase due to contact with liquid electrolytes. Many technical strategies have been developed for addressing these two issues in the past decades. Among them, atomic and molecular layer deposition (ALD and MLD) have been drawing more and more efforts, owing to a series of their unique capabilities. ALD and MLD enable a variety of inorganic, organic, and even inorganic-organic hybrid materials, featuring accurate nanoscale controllability, low process temperature, and extremely uniform and conformal coverage. Consequently, ALD and MLD have paved a novel route for tackling the issues of alkali metal anodes. In this review, we have made a thorough survey on surface coatings via ALD and MLD, and comparatively analyzed their effects on improving the safety and stability of alkali metal anodes. We expect that this article will help boost more efforts in exploring advanced surface coatings via ALD and MLD to successfully mitigate the issues of alkali metal anodes.

Bioactive Scaffold Fabricated by 3D Printing for Enhancing Osteoporotic Bone Regeneration.

We develop a poly (lactic-co-glycolic acid)/ß-calcium phosphate (PLGA/TCP)-based scaffold through a three-dimensional (3D) printing technique incorporating icaritin (ICT), a unique phytomolecule, and secretome derived from human fetal mesenchymal stem cells (HFS), to provide mechanical support and biological cues for stimulating bone defect healing. With the sustained release of ICT and HFS from the composite scaffold, the cell-free scaffold efficiently facilitates the migration of MSCs and promotes bone regeneration at the femoral defect site in the ovariectomy (OVX)-induced osteoporotic rat model. Furthermore, mechanism study results indicate that the combination of ICT and HFS additively activates the Integrin-FAK (focal adhesion kinase)-ERK1/2 (extracellular signal-regulated kinase 1/2)-Runx2 (Runt-related transcription factor 2) axis, which could be linked to the beneficial recruitment of MSCs to the implant and subsequent osteogenesis enhancement. Collectively, the PLGA/TCP/ICT/HFS (P/T/I/S) bioactive scaffold is a promising biomaterial for repairing osteoporotic bone defects, which may have immense implications for their translation to clinical practice.

New use for old drug: Local delivery of puerarin facilitates critical-size defect repair in rats by promoting angiogenesis and osteogenesis.

Objectives: Large bone defect repair is a challenging clinical problem due to limited self-repair ability. A well-designed bone filling product should possess the ability to induce tissue in-growth and facilitate neovascularization and new bone formation. Puerarin has been used in clinics for a long time, and recently it was found to be able to promote osteogenesis. This study aimed to investigate a puerarin-based drug/delivery combination implant for promoting large bone defect repair. Methods: Puerarin was incorporated into the poly (lactic-co-glycolic acid)/ß-calcium phosphate (PLGA/TCP, PT) to form a porous PLGA/TCP/Puerarin (PTP) composite scaffold by low-temperature rapid prototyping technology. Its structural and degradation were analyzed in vitro. Then we employed a rat calvarial critical size defect model to assess the potency of the PTP scaffold. MC3T3-E1 cells and EA. hy 926 â€‹cells were used to investigate the underlying mechanism. Results: PTP scaffold inherited all advantages of PT scaffold in structural, mechanical, and biodegradation, meanwhile puerarin stably and continuously released from PTP scaffold and lasted for 5 months in vitro. At 8 weeks after implantation, the PTP scaffold triggered new bone formation in the macro-pores of the scaffold and inside the scaffold accompanied by the degrading materials. The underlying mechanism revealed that the PTP scaffold induced vascular infiltration and recruit repair cells through stimulating vascular endothelial growth factor (VEGF) and bone morphogenetic protein 2 (BMP-2) expressions to promote angiogenesis and osteogenesis. Conclusion: Puerarin-enriched porous PTP scaffold was a promising local delivery system with sustained release of puerarin for facilitating defect repair through getting synergistic angiogenic and osteogenic effects. The Translational Potential of this Article: The PTP scaffold presents a potential drug/device combination medical implant for large bone defect repair, which also provides a new and innovative application for the "old drug" puerarin.

Identification of Hub Genes in Colorectal Adenocarcinoma by Integrated Bioinformatics.

An improved understanding of the molecular mechanism of colorectal adenocarcinoma is necessary to predict the prognosis and develop new target gene therapy strategies. This study aims to identify hub genes associated with colorectal adenocarcinoma and further analyze their prognostic significance. In this study, The Cancer Genome Atlas (TCGA) COAD-READ database and the gene expression profiles of GSE25070 from the Gene Expression Omnibus were collected to explore the differentially expressed genes between colorectal adenocarcinoma and normal tissues. The weighted gene co-expression network analysis (WGCNA) and differential expression analysis identified 82 differentially co-expressed genes in the collected datasets. Enrichment analysis was applied to explore the regulated signaling pathway in colorectal adenocarcinoma. In addition, 10 hub genes were identified in the protein-protein interaction (PPI) network by using the cytoHubba plug-in of Cytoscape, where five genes were further proven to be significantly related to the survival rate. Compared with normal tissues, the expressions of the five genes were both downregulated in the GSE110224 dataset. Subsequently, the expression of the five hub genes was confirmed by the Human Protein Atlas database. Finally, we used Cox regression analysis to identify genes associated with prognosis, and a 3-gene signature (CLCA1-CLCA4-GUCA2A) was constructed to predict the prognosis of patients with colorectal cancer. In conclusion, our study revealed that the five hub genes and CLCA1-CLCA4-GUCA2A signature are highly correlated with the development of colorectal adenocarcinoma and can serve as promising prognosis factors to predict the overall survival rate of patients.

Promoting osteointegration effect of Cu-alloyed titanium in ovariectomized rats.

Osteoporosis is a common skeletal disease making patients be prone to the osteoporotic fracture. However, the clinical implants made of titanium and its alloys with a poor osseointegration need a long time for healing and easily to loosening. Thus, a new class of Cu-alloyed titanium (TiCu) alloys with excellent mechanical properties and bio-functionalization has been developed. In this study, the osteoporosis modeled rats were used to study the osteointegration effect and underlying mechanism of TiCu. The results showed that after implantation for 4 weeks, TiCu alloy could promote the reconstruction of vascular network around the implant by up-regulating vascular endothelial growth factor expression. After 8 weeks, it could further promote the proliferation and differentiation of osteoblasts, mineralization and deposition of collagens, and then significantly increasing bone mineral density around the implant. In conclusion, TiCu alloy would enhance the fixation stability, accelerate the osteointegration, and thus reduce the risk of aseptic loosening during the long-term implantation in the osteoporosis environment. This study was the first to report the role and mechanism of a Cu-alloyed metal in promoting osteointegration in osteoporosis environment, which provides a new attractive support for the improvement of future clinical applications of Cu-alloyed antibacterial titanium alloys.

Atomic layer deposition of lithium zirconium oxides for the improved performance of lithium-ion batteries.

Recently there has been increasing interest to develop lithium-containing films as solid-state electrolytes or surface coatings for lithium-ion batteries (LIBs) and related systems. In this study, we for the first time investigated the thin film growth of lithium zirconium oxides (LixZryO or LZOs) through combining two individual atomic layer deposition (ALD) processes of ZrO2 and LiOH, i.e., sub-ALD of ZrO2 and LiOH. We revealed that the hygroscopic nature of the LiOH component has a big impact on the growth of LZOs. We found that an increased temperature to 225 °C was more effective than an elongated purge to mitigate the adverse effects of physisorbed H2O. We further discovered that, during the resultant LZO super-ALD processes, the growth of sub-ALD LiOH has been promoted while the growth of sub-ALD ZrO2 has been inhibited. In this study, a suite of instruments has been applied to characterize the LZO super-ALD processes and the resultant LZO films, including in situ quartz crystal microbalance (QCM), scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM), atomic force microscopy (AFM), synchrotron-based X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Furthermore, we applied the resulting LZO films over LiNi0.6Mn0.2Co0.2O2 (NMC622) cathodes in LIBs and demonstrated that the LZO coating films could evidently improve the lithium-ion insertion and extraction rates of the NMC622 electrodes up to 3.4 and 2.6 times, respectively. The LZO-coated NMC622 cathodes exhibited much better performance than the uncoated NMC622 ones.
