    Abstract Contemplating the actual leaders of entrepreneurial firms and socio demographic dissimilarity between leaders and their teams, this study adopts panel data on the entrepreneurial firms of the China's Growth Enterprise Market and empirically examines the influence of chair power on research and development (R&D) intensity of entrepreneurial firms from the perspective of social identity. The results indicate that chair power positively affects entrepreneurial firms' R&D intensity. The chair-team sociodemographic dissimilarity moderates the relationship in such a way that chair power is negatively related to entrepreneurial firms' R&D intensity only when chair-team sociodemographic dissimilarity is high. The execution of robustness checks authenticates the veracity of the empirical results.

    Abstract Background: Osteosarcoma is a common type of bone tumors and frequently occurs in children and adolescents. Cancer stem cells (CSCs) are a unique sub-type of self-renewal cancer cells and the stemness of cancer cells are involved in the spread, recurrence, metastasis, and even therapeutic resistance. However, the regulation mechanisms of CSCs in osteosarcoma are poorly understood. Circular RNA (circRNA) is a unique sort of non-coding RNAs and widely participate in the modulation of cancer progression.
    Methods: In this study, we identified the critical function of circular RNA circPIP5K1A in stemness of osteosarcoma cells.
    Results: CircPIP5K1A expression was significantly enhanced in clinical osteosarcoma tissues compared with the adjacent normal tissues. The depletion of circPIP5K1A by siRNA repressed osteosarcoma cell viabilities and induced osteosarcoma cell apoptosis. The suppression of circPIP5K1A attenuated the capabilities of invasion and migration of osteosarcoma cells. The circPIP5K1A knockdown increased E-Cadherin expression and decreased Vimentin expression in osteosarcoma cells. The sphere formation abilities of osteosarcoma cells were repressed by the depletion of circPIP5K1A. The CD133
    Conclusion: In conclusion, we identified that circular RNA circPIP5K1A contributed to cancer stemness of osteosarcoma by miR-515-5p/YAP axis. Targeting circPIP5K1A may be considered as a potential therapeutic strategy for osteosarcoma treatment.

    Abstract In this study, nanoparticles loaded with active components from Polygonum orientale L. (PO), a traditional Chinese herb known for its anti-myocardial ischemic properties, were investigated for cardio-protective properties. Specifically, OVQ-Nanoparticles (OVQ-NPs) with Orientin (Ori), Vitexin (Vit), and Quercetin (Que) was obtained by double emulsion-solvent evaporation method. The OVQ-NPs exhibited a spherical shape, with a uniform size distribution of 136.77 ± 3.88 nm and a stable ζ-potential of -13.40 ± 2.24 mV. Notably, these nanoparticles exhibited a favorable sustained-release characteristic, resulting in an extended circulation time within the living organism. Consequently, the administration of these nanoparticles resulted in significant improvements in electrocardiograms and heart mass index of myocardial ischemic rats induced by isoproterenol, as well as decreased serum levels of CK, LDH, and AST. Furthermore, the results of histopathological examination, such as H&E staining and TUNEL staining, confirmed a reduced level of cardiac tissue pathology and apoptosis. Moreover, the quantification of biochemical indicators (SOD, MDA, GSH, NO, TNF-α, and IL-6) demonstrated that OVQ-NPs effectively mitigated myocardial ischemia by regulating oxidative stress and inflammatory pathways. In conclusion, OVQ-NPs demonstrate promising therapeutic potential as an intervention for myocardial ischemia, providing a new perspective on traditional Chinese medicine treatment in this area.

    Abstract Scutellariae Radix extract is one of the important components in Shuganning Injection. In this study, an ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method was established for simultaneously determining five components in Shuganning Injection and Scutellariae Radix extract in bile, urine, and feces of rats, so as to reveal the difference in the excretion process of Shuganning Injection and Scutellariae Radix extract in rats and explore the law of the excretion process of the five components in vivo before and after the compatibility of Scutellariae Radix. Rats were injected with Shuganning Injection and Scutellariae Radix extract(4.2 mL·kg~(-1)), respectively, and the excretion of baicalin, baicalein, oroxylin A, oroxylin A-7-O-β-D-glucuronide, and scutellarin in bile, urine, and feces of rats in 24 h was observed. The results showed that except for baicalin, the other four index components were excreted as prototype components in a high proportion after intravenous injection of Shuganning Injection and Scutellariae Radix extract in rats, respectively. The excretion of each component was relatively high in urine and less in feces and bile. After the compatibility of Scutellariae Radix extract, the accumulative excretion of five index components in rats all decreased. Among them, the cumulative excretion of baicalein in bile, urine, and feces significantly decreased by 26.67%, 48.11%, and 31.01%. The cumulative excretion of baicalin in bile, urine, and feces decreased significantly by 70.69%, 19.43%, and 31.22%. The result showed that the five index components in Scutellariae Radix extract were mainly excreted by the kidneys, and other components in Shuganning Injection delayed the excretion process and prolonged the residence time. This study is of great significance for elucidating the compatibility rationality of Shuganning Injection.

    Abstract Aseisimic earth fissures are complex consequences of groundwater withdrawal and natural hydrogeologic conditions. This paper aims to improve the understanding of the mechanism of earth fissuring and investigate the relative importance of various factors to fissure activity, including bedrock geometry, piezometric depletion, compressibility and thickness of the exploited aquifer. For these purposes, a test case characterized by an impermeable and incompressible rock ridge in a subsiding basin is developed, where stress/displacement analyses and fissure state are predicted using an interface-finite element model. Three different methods for global sensitivity analysis are used to quantify the extent of the fissure opening to the aforementioned factors. The conventional sampling based Sobol’ sensitivity analysis is compared to two surrogate based methods, the general polynomial chaos expansion based Sobol’ analysis and a feature importance evaluation of a gradient boosting decision tree model. Numerical results indicate that earth fissure is forming in response to tensile stress accumulation above the ridge associated to pore-pressure depletion, inducing the fissure opening at land surface with further downward propagation. Sensitivity analysis highlights that the geometry of bedrock ridge is the most influential feature. Specifically, the fissure grows more when the ridge is steeper and closer to the land surface. Pore pressure depletion is a secondary feature and required to reach a certain threshold to activate the fissure. As for this specific application, the gradient boosting tree is the most suitable method for its better performance in capturing fissure characteristics.

    Abstract Objective: The ataxia telangiectasia mutated (
    Methods: We retrieved and identified the available case-control studies that met the inclusion criteria from the PubMed, Web of Science, and Embase databases. Odds ratio (OR) and 95% confidence intervals (CIs) were used to measure the association between rs1801516 and cancer risk. Additionally, we performed sensitivity, subgroup, and publication bias analyses.
    Results: After inclusion criteria were met, the meta-analysis included 29 studies, with 9,453 cancer patients (cases) and 14,646 controls. No association was found between rs1801516 and cancer risk (pooled OR = 0.911; 95% CI, 0.740-1.123). Concordantly, no association was found between rs1801516 and cancer risk after subgroup analysis by source of controls, cancer type, or ethnicity, which confirmed the finding of the dominant model that this SNP is not involved in the occurrence of cancer.
    Conclusions: Through this meta-analysis, we found no association between rs1801516 and cancer occurrence as a risk factor. These data provide useful information for future case-control studies on cancer etiology.
