ABSTRACT This research investigates the influence of electrochemical surface treatment on the mechanical properties of carbon fiber reinforced epoxy composites through systematic parameter optimization and comprehensive characterization. The study established optimal treatment conditions using ammonium bicarbonate electrolyte at 35°C, achieving enhanced interfacial properties through controlled surface modification. Surface characterization revealed the development of hierarchical surface features with primary grooves (0.5–1 μm width) and secondary nano-scale features (50–200 nm), accompanied by a significant increase in surface polarity from 0.20 to 0.41. XPS analysis demonstrated the successful introduction of oxygen-containing functional groups, with hydroxyl, carbonyl, and carboxyl groups showing particular prominence. The modification depth was confined to 200–300 nm, preserving the fiber’s core structure. Mechanical testing revealed substantial improvements in composite performance, evidenced by enhanced load transfer efficiency and a transition in failure modes. The treatment resulted in improved damage initiation stress (from 985 MPa to 1290 MPa) and initial linear modulus (from 135.2 GPa to 149.6 GPa). Additionally, the composite compressive modulus increased from 128.5 ± 3.8 GPa to 142.3 ± 4.2 GPa, representing a 10.7% improvement. Furthermore, surface roughness was significantly enhanced, with the arithmetic mean roughness (Ra) increasing from 8.2 ± 0.5 nm to 45.7 ± 2.3 nm.

Abstract Current pipe jacking projects predominantly use C50 concrete pipes, which are prone to cracking and failure under jacking forces during complex construction. This study investigates the mechanical performance and failure mechanisms of C150 ultra-high performance fibre reinforced concrete (UHPFRC) pipes through full-scale trilateral loading test and numerical simulation. Key outcomes include crack load (232 kN/m), damage load (452 kN/m), and maximum displacements (64.3 mm horizontal, 71.6 mm vertical). Radial loading induced four primary cracks along the inner/outer left-right surfaces of the pipe, accompanied by extensive secondary crack networks. Damage progression began with concrete spalling at the top/bottom due to crack propagation, followed by reinforcement yielding and structural collapse. A predictive model for crack load and ultimate bearing capacity was developed, validated by experimental data. ABAQUS finite element simulations demonstrated excellent correlation with experiments, accurately reproducing macroscopic damage patterns. Notably, UHPFRC pipes exhibited 2.55-fold higher radial bearing capacity compared to C50 counterparts. This research establishes UHPFRC as a superior material for pipe jacking applications, offering enhanced structural integrity and reliability.

Abstract The complex pathogenesis of castration-resistant prostate cancer (CRPC) makes it challenging to identify effective treatment methods. Matrix metalloproteinase (MMP)-12 can degrade elastin as well as various extracellular matrix (ECM) components, which is associated with cancer progression. However, the relationship between MMP-12 and CRPC progression is poorly understood. In this study, we observed the effect of MMP-12 on the progression of CRPC and further explored its potential mechanism of action. High levels of MMP-12 were observed in patients with CRPC. We therefore developed cell co-culture and mouse models to study the function of MMP-12. Silencing MMP-12 in CRPC cells disrupted lipid utilization and autophagy marker expression via the CD36/CPT1 and P62/LC3 pathways, respectively, leading to reduced CRPC cell migration and invasion. Moreover, animal experiments confirmed that MMP-12-knockdown CRPC xenograft tumors exhibited reduced tumor growth, and the mechanisms involved the promotion of cancer cell autophagy and the inhibition of lipid catabolism. According to our results, MMP-12 played important roles in the progression of CRPC by disrupting adipocyte maturation and regulating cancer migration and invasion via the modulation of autophagy and lipid catabolism pathways.

Abstract Background With the fast-paced advancements of robot technology, human–robot interaction (HRI) has become increasingly popular and complex, and self-efficacy in HRI has received extensive attention. Despite its popularity, this topic remains understudied in China. Objective In order to provide a psychometrically sound instrument in China, this study aimed to translate and validate the Self-Efficacy in Human–Robot Interaction Scale (SE-HRI) in two Chinese adult samples (N1 = 300, N2 = 500). Methods The data was analyzed by SPSS 26.0 and Amos 24.0. Item analysis and exploratory factor analysis were conducted using Sample 1 data. Confirmatory factor analysis, criterion-related validity analysis, and reliability analysis were then performed using Sample 2 data. Results The results revealed that the Chinese SE-HRI scale consisted of 13 items in a two-factor model, suggesting a good model fit. Moreover, general self-efficacy and willingness to accept the use of artificial intelligence (AI) were both positively correlated with self-efficacy in HRI, while negative attitudes toward robots showed an inverse correlation, proving the Chinese SE-HRI scale exhibited excellent criterion-related validity. Conclusion The Chinese SE-HRI scale is a reliable assessment tool for evaluating self-efficacy in HRI in China. The study discussed implications and limitations, and suggested future directions.

ABSTRACT In order to enhance the quality and mechanical properties of 3D printing carbon fiber reinforced composite (CFRP) workpiece, this paper prepares 3D printing CFRP laminates by proposing a layered coherent composite scanning path, and carries out orthogonal tests and single factor tests to disclose the effects of different process parameters (i.e., layer thickness, first layer thickness, nozzle temperature and printing speed) on the mechanical performance of the CFRP workpieces. Moreover, The grey relation analysis method is used to analyze the multi-objective parameters of the orthogonal tests results and the process parameters of 3D printing CFRP are optimized based on the tests results. The research results show that the process parameters of 3D printed CFRP can be ranked as delamination thickness, nozzle temperature, first layer thickness and printing speed, in descending order of the impact on the mechanical property of the CFRP laminates. the optimal process parameters for 3D printing include a layer thickness of 0.25 mm, a first layer thickness e of 0.2 mm, a nozzle temperature of 180°C, and printing speed of 45 mm/s. Under this parameter combination, the tensile strength, bending strength, and the interlaminar shear strength (ILSS) of the samples are 52.77 MPa, 276.63 MPa and 38.56 Mpa respectively, and the grey correlation degree increased to 0.845.

Abstract Objectives To determine whether tinnitus negatively impacts the accuracy of sound source localization in participants with normal hearing. Methods Seventy-five participants with tinnitus and 74 without tinnitus were enrolled in this study. The accuracy of sound source discrimination on the horizontal plane was compared between the two participant groups. The test equipment consisted of 37 loudspeakers arranged in a 180° arc facing forward with 5° intervals between them. The stimuli were pure tones of 0.25, 0.5, 1, 2, 4, and 8 kHz at 50 dB SPL. The stimuli were divided into three groups: low frequency (LF: 0.25, 0.5, and 1 kHz), 2 kHz, and high frequency (HF: 4 and 8 kHz) stimuli. Results The Root Mean Square Error (RMSE) score of all the stimuli in the tinnitus group was significantly higher than that in the control group (13.45 ± 3.34 vs. 11.44 ± 2.56, p = 4.115, t < 0.001). The RMSE scores at LF, 2 kHz, and HF were significantly higher in the tinnitus group than those in the control group (LF: 11.66 ± 3.62 vs. 10.04 ± 3.13, t = 2.918, p = 0.004; 2 kHz: 16.63 ± 5.45 vs. 14.43 ± 4.52, t = 2.690, p = 0.008; HF: 13.42 ± 4.74 vs. 11.14 ± 3.68, t = 3.292, p = 0.001). Thus, the accuracy of sound source discrimination in participants with tinnitus was significantly worse than that in those without tinnitus, despite the stimuli frequency. There was no difference in the ability to localize the sound of the matched frequency and other frequencies (12.86 ± 6.29 vs. 13.87 ± 3.14, t = 1.204, p = 0.236). Additionally, there was no correlation observed between the loudness of tinnitus and RMSE scores (r = 0.096, p = 0.434), and the Tinnitus Handicap Inventory (THI) and RMSE scores (r = −0.056, p = 0.648). Conclusions Our present data suggest that tinnitus negatively impacted sound source localization accuracy, even when participants had normal hearing. The matched pitch and loudness and the impact of tinnitus on patients’ daily lives were not related to the sound source localization ability.

Abstract Objective MicroRNA-29a-3p has been reported in a variety of cancers, but its role in hypopharyngeal cancer remains unclear. This study was to determine the role of microRNA-29a-3p in the occurrence and development of hypopharyngeal cancer. Methods 40 patients with hypopharyngeal cancer who underwent surgery in the Affiliated Hospital of Jining Medical University from April 2013 to November 2017 were selected for this study. The cancer tissue samples of the patients were collected, and the patients were followed up for three years. The expression of microRNA-29a-3p in tissue samples was detected by in situ hybridization with fluorescent probe, and the relationships among microRNA-29a-3p and clinicopathological factors, postoperative recurrent-metastasis, survival time were studied. Immunohistochemical was used to detect the expression of Ki67 and E-cadherin in tissue samples. Results Combined with HE staining results showed that microRNA-29a-3p expression was relatively high in non-cancer tissue cells (red blood cells and fibroblasts in tumor interstitial vessels), but was relatively low in cancer tissue and cells. According to the follow-up data of 40 patients with hypopharyngeal cancer, tumor size, T-stage, tumor differentiation, postoperative recurrent-metastasis of hypopharyngeal cancer patients were significantly negatively correlated with microRNA-29a-3p (p< 0.05). Immunohistochemica results further confirmed that microRNA-29a-3p was negatively correlated with the expression of Ki67 and E-cadherin. The survival time of patients positively related with microRNA-29a-3p expression (p< 0.05). Moreover, ROC curve analysis showed that the area under the curve of the combined detection of miRNA-29a-3p+Ki67+E-cadherin was larger than that of the single detection of the three indexes. Conclusions The expression of microRNA-29a-3p is closely related to the occurrence, development and prognosis of hypopharyngeal cancer, and it affects the proliferation and invasion. This indicates that microRNA-29a-3p serves as a therapeutic target for the occurrence and development of hypopharyngeal cancer.

Abstract Burley tobacco-leaf protein extracted by alkali and precipitated by acid was hydrolyzed enzymatically, and optimum protease and hydrolysis parameters were determined. Pepsin was best and gave the highest hydrolysis rate (15.55%). As per results of the single-factor test, optimum hydrolysis conditions were: temperature 37 °C, pH 2, and an [E]/[S] ratio of 5%. These hydrolysis conditions were optimized by an orthogonal experiment that rendered the same results as the single factor experiment. The ratio of essential to total amino acids and that of essential to non-essential amino acids contained in the burley tobacco-leaf protease hydrolysate were higher than the FAO/WHO standard values of 0.4 and 0.6, among which hydrophobic amino acid content was the highest, followed by negatively and positively charged amino acid contents. In vitro antioxidant experiments showed that the scavenging rates of DPPH, superoxide anion, and hydroxyl radicals of tobacco-leaf protein hydrolysates were higher than those before hydrolysis. Further, the hydroxyl radical-scavenging rate was the most significant, and total antioxidant capacity was improved. The nutritive value of the burley tobacco-leaf protein hydrolysate improved upon pepsin-mediated hydrolysis, and the antioxidant activity was better. These results provide a theoretical basis for further development and utilization of tobacco protein resources.

Abstract Despite the use of Maillard reaction products (MRPs) as food flavoring and coloring agents, they are also known to constitute acrylamide, heterocyclic amines, advanced glycosylation end products, and precursors of low molecular weight compounds. The very little is known about the toxicology of peony seed meal-derived MRPs. In this study, sub-chronic toxicity of peony seed meal derived MRPs was evaluated in Sprage-Dawley (SD) rats. Results showed that the body weight, hematology and serum biochemistry, organ coefficient and histopathology of SD rats with daily intake of peony seed meal-derived MRPs lower than 0.45 g/kg were not affected. After feeding with peony seed meal-derived MRPs for 13-weeks, there were no significant toxic effect on either male or female rats. This study provides a theoretical basis for the safety of MRPs derived from the reactants of enzymatic hydrolysis of peony seed meal.

This study evaluated the effects of perioperative nutrition management by a multidisciplinary team on nutrition and postoperative complications of patients with esophageal cancer. A total of 239 patients with esophageal cancer who underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between February 2019 and February 2020 were included in the study. They were divided into the experimental group (120 patients) and the control group (119 patients) using the random number table method. Control group patients received routine diet management and experimental group patients received perioperative nutrition management by a multidisciplinary team. The differences of nutriture and postoperative complications between the two groups were compared. At 3 and 7 days after surgery, the experimental group patients had higher total protein and albumin levels (P<0.05), shorter postoperative anal exhaust time (P<0.05), lower incidence of postoperative gastrointestinal adverse reactions, pneumonia, anastomotic fistula, hypoproteinemia (P<0.05), and lower hospitalization costs (P<0.05) than the control group. Nutrition management by a multidisciplinary team effectively improved the nutriture of patients, promoted the rapid recovery of postoperative gastrointestinal function, reduced postoperative complications, and reduced hospitalization costs. 23 201 202 120 (12 119 (11 method compared surgery P<0.05, P005 P P<0.05 , 0 05 reactions pneumonia fistula (P<0.05 function 2 20 12 (1 11 P00 P<0.0 (P<0.0 1 ( P0 P<0.

Abstract Chemotherapy is the main treatment option for advanced osteosarcoma, which is the most common type of primary bone malignancy. However, patients develop resistance rapidly and many succumb to the disease. Niclosamide, an anthelmintic drug, has been recently identified to display potent and selective anti-cancer activity. In this work, we show that niclosamide at sub-micromolar concentrations inhibits proliferation and migration, and induces apoptosis in both parental and chemo-resistant osteosarcoma cells, with much less toxicity in normal osteoblastic cells. Interestingly, chemo-resistant osteosarcoma cells are more sensitive to niclosamide compared to parental cells. We further identify that inhibition of β-catenin is the underlying mechanism of niclosamide’s action in osteosarcoma cells. In addition, we reveal that chemo-resistant osteosarcoma cells display increased β-catenin activity compared to parental cells, which might explain the hypersensitivity of chemo-resistant cells to niclosamide. Our work provides pre-clinical evidence that niclosamide can be repurposed for treating osteosarcoma. Our findings also suggest the therapeutic value of β-catenin to overcome osteosarcoma chemo-resistance. malignancy However disease Niclosamide drug anticancer anti cancer submicromolar sub micromolar migration chemoresistant chemo resistant Interestingly βcatenin β catenin niclosamides s addition preclinical pre clinical chemoresistance. chemoresistance resistance. chemo-resistance

Abstract Hydrogen sulfide (H2S) is recognized for its beneficial role in postharvest fruit and vegetable preservation. Postharvest goji berries are easy to mildew and rot which reduce the nutritional value, flavor, and shelf life. Hydrogen sulfide treatment could improve the quality attributes of postharvest goji berry (Lycium barbarum L.); however, it is not clear that the effects of H2S at the transcriptional level in postharvest goji berries. Our data revealed that the differentially expressed genes (DEGs) of fresh goji fruits after H2S treatment were different with different storage time. There were 523 DEGs in the three comparison groups after H2S treatment on the 2nd, 4th and 6th day of storage. In the pathway of KEGG metabolic function, most of the DEGs were conserved in carbohydrate metabolism, secondary metabolites biosynthesis, amino acid metabolism, lipid metabolism, energy metabolism, the metabolic pathways of terpenoids and polyketones. The genes in the phenylpropanoid biosynthesis, flavonoid biosynthesis, starch, and sucrose metabolism pathway were selected and validated by quantitative real-time PCR (qRT-PCR). Our results provide insights into the effect of H2S on postharvest goji berries at the transcriptional level and provide the basis for application of H2S as gas regulator for preservation of goji berry.
