    Gang Niu1,2, Zhaoyang Jin2, Wei Zhang3,*, Yiqun Huang3

    Structural Durability & Health Monitoring, Vol., , DOI:10.32604/sdhm.2023.044580

    Abstract Amid urbanization and the continuous expansion of transportation networks, the necessity for tunnel construction and maintenance has become paramount. Addressing this need requires the investigation of efficient, economical, and robust tunnel reinforcement techniques. This paper explores fiber reinforced polymer (FRP) and steel fiber reinforced concrete (SFRC) technologies, which have emerged as viable solutions for enhancing tunnel structures. FRP is celebrated for its lightweight and high-strength attributes, effectively augmenting load-bearing capacity and seismic resistance, while SFRC’s notable crack resistance and longevity potentially enhance the performance of tunnel segments. Nonetheless, current research predominantly focuses on experimental analysis, lacking comprehensive theoretical models. To… More >

    Oncology Research, Vol., , DOI:10.32604/or.2024.046679

    Abstract Background: EBV-miR-BARTs exhibit significant relevance in epithelial tumors, particularly in EBV-associated gastric and nasopharyngeal cancers. However, their specific mechanisms in the initiation and progression of gastric cancer remain insufficiently explored. Material and Methods: Initially, EBV-miRNA-BART6-5p and its target gene SMAD4 expression were assessed in EBV-associated gastric cancer tissues and cell lines. Subsequent transfection induced overexpression of EBV-miRNA-BART6-5p in AGS and MKN-45, and downregulation in EBV-positive cells (SUN-719). The subsequent evaluation aimed to observe their impact on gastric cancer cell proliferation, migration, and glycolytic processes, with the TGF-β/SMAD4 signaling pathway value clarified using a TGF-β inhibitor. Results: EBV-miRNA-BART6-5p exhibits pronounced upregulation… More >

    A Rapid Parameter of Enzyme-Treated Cellulosic Material Revealed by Reducing Sugar Release

    Verônica Távilla Ferreira Silva, Adriane Maria Ferreira Milagres*

    Journal of Renewable Materials, Vol., , DOI:10.32604/jrm.2023.045726

    Abstract This study was conducted to evaluate the effectiveness of enzymes in purifying and reducing the degree of polymerization of cellulose for the production of dissolving pulp. Our goal was to determine the contributions of xylanase (X) and endoglucanase (EG) in the treatment of pulp, specifically by quantifying the formation of soluble and insoluble reducing sugars using the dinitrosalycilic acid (DNS) test. Predominantly, the release of soluble reducing sugars (RSSol) was enhanced after xylanase treatment, while endoglucanase (EG) treatment led to changes in insoluble reducing sugars (RSIns). The maximum synergism was observed for RSIns when a high ratio of endoglucanase to… More > Graphic Abstract

    Self-Compassion Moderates the Effect of Contingent Self-Esteem on Well-Being: Evidence from Cross-Sectional Survey and Experiment

    Ruirui Zhang1, Xuguang Zhang2, Minxin Yang3, Haoran Zhang4,5,*

    International Journal of Mental Health Promotion, Vol., , DOI:10.32604/ijmhp.2023.045819

    Abstract Contingent self-esteem captures the fragile nature of self-esteem and is often regarded as suboptimal to psychological functioning. Self-compassion is another important self-related concept assumed to promote mental health and well-being. However, research on the relation of self-compassion to contingent self-esteem is lacking. Two studies were conducted to explore the role of self-compassion, either as a personal characteristic or an induced mindset, in influencing the effects of contingent self-esteem on well-being. Study 1 recruited 256 Chinese college students (30.4% male, mean age = 21.72 years) who filled out measures of contingent self-esteem, self-compassion, and well-being. The results found that self-compassion moderated… More >

    LC-NPLA: Label and Community Information-Based Network Presentation Learning Algorithm

    Shihu Liu, Chunsheng Yang*, Yingjie Liu

    Intelligent Automation & Soft Computing, Vol., , DOI:10.32604/iasc.2023.040818

    Abstract Many network presentation learning algorithms (NPLA) have originated from the process of the random walk between nodes in recent years. Despite these algorithms can obtain great embedding results, there may be also some limitations. For instance, only the structural information of nodes is considered when these kinds of algorithms are constructed. Aiming at this issue, a label and community information-based network presentation learning algorithm (LC-NPLA) is proposed in this paper. First of all, by using the community information and the label information of nodes, the first-order neighbors of nodes are reconstructed. In the next, the random walk strategy is improved… More >

    BIOCELL, Vol., , DOI:10.32604/biocell.2023.045640

    Abstract Background: L-dopa (Levodopa) is well known for managing PD (Parkinson’s disease); however, its prolonged use caused dyskinesia (LID). Due to the varied presentation of LID, effective treatment options are scarce. Flavonoids reported their neuroprotective activity by ameliorating acetylcholinesterase, monoamine oxidase, and neuroinflammation. Kaempferol is another flavonoid bearing these potentials. Aim: To evaluate neuroprotective activity of kaempferol in dyskinetic rats. Methods: PD was developed in Sprague-Dawley rats by injecting combination of L-ascorbic acid (10 µL) + 6-OHDA (12 µg) in medial forebrain bundle to induce neuronal damage in substantial nigra (SNr). LID was induced by administrating combination of L-dopa (20 mg/kg)… More > Graphic Abstract

    VAN THI TUONG NGUYEN1,2, KHUONG DUY PHAM1,2,3, HUONG THI QUE CAO1,2, PHUC VAN PHAM1,2,*

    BIOCELL, Vol., , DOI:10.32604/biocell.2023.043664

    Abstract Mesenchymal stem cells (MSCs) have been proposed in regenerative medicine, especially for angiogenic purposes, due to their potential to self-renew, differentiate, and regulate the microenvironment. Peripheral vascular diseases, which are associated with reduced blood supply, have been treated but not cured. An effective therapy is to recover blood supply via vessel regeneration in the affected area, and MSCs appear to be promising for such conditions. Several studies aimed to explore the role of MSCs in performing angiogenesis and have revealed numerous potential methods to enhance MSC capacity in vessel formation. Efforts have been made to modify standard MSCs to optimize… More > Graphic Abstract

    BIOCELL, Vol., , DOI:10.32604/biocell.2023.028336

    Abstract Objectives: Colorectal cancer (CRC) is a serious threat to human health worldwide. Oxaliplatin is a platinum analog and is widely used to treat CRC. However, resistance to oxaliplatin restricts its effectiveness and application while its target recognition and mechanism of action also remain unclear. Therefore, we aimed to develop an oxaliplatin-resistant prognostic model to clarify these aspects. Methods: We first obtained oxaliplatin-resistant and parental cell lines, and identified oxaliplatin-resistant genes using RNA sequencing (RNA-seq) and differential gene analysis. We then acquired relevant data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Cox regression and Least Absolute… More > Graphic Abstract
