background: We previously reported that activation of the cell cycle in human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) enhances their remuscularization capacity after human cardiac muscle patch transplantation in infarcted mouse hearts. Herein, we sought to identify the effect of magnesium lithospermate b (MLb) on hiPSC-CMs during myocardial repair using a myocardial infarction (MI) mouse ***: In C57bL/6 mice, MI was surgically induced by ligating the left anterior descending coronary artery. The mice were randomly divided into five groups (n = 10 per group); a MI group (treated with phosphate-buffered saline only), a hiPSC-CMs group, a MLb group, a hiPSC-CMs + MLb group, and a Sham operation group. Cardiac function and MLb therapeutic efficacy were evaluated by echocardiography and histochemical staining 4 weeks after surgery. To identify the associated mechanism, nuclear factor (NF)-κb p65 and intercellular cell adhesion molecule-1 (ICAM1) signals, cell adhesion ability, generation of reactive oxygen species, and rates of apoptosis were detected in human umbilical vein endothelial cells (HUVECs) and ***: After 4 weeks of transplantation, the number of cells that engrafted in the hiPSC-CMs + MLb group was about five times higher than those in the hiPSC-CMs group. Additionally, MLb treatment significantly reduced tohoku hospital pediatrics-1 (THP-1) cell adhesion, ICAM1 expression, NF-κb nuclear translocation, reactive oxygen species production, NF-κb p65 phosphorylation, and cell apoptosis in HUVECs cultured under hypoxia. Similarly, treatment with MLb significantly inhibited the apoptosis of hiPSC-CMsvia enhancing signal transducer and activator of transcription 3 (STAT3) phosphorylation and b-cell lymphoma-2 (bCL2) expression, promoting STAT3 nuclear translocation, and downregulating bCL2-Associated X, dual specificity phosphatase 2 (DUSP2), and cleaved-caspase-3 expression under hypoxia.

Study on the tunnel shape and soil-lining interaction influencing the lining behavior under seismic loading

引用

Earthquake Engineering and Engineering Vibration 2024年第04期 845-862页

作者： Van Vi Pham Ngoc Anh Do Piotr Osinski Ngoc Thai Do daniel Dias Sustainable Development in Underground Engineering Research Team Hanoi University of Mining and Geology Department of Underground and Mining Construction Faculty of Civil Engineering Hanoi University of Mining and Geology Department of Geotechnical Engineering Institute of Civil Engineering Warsaw University of Life Sciences-SGGW Laboratory 3SR Grenoble Alpes University

The response of tunnels subjected to seismic loading is a complex mechanism and depends not only on the seismic nature but also on tunnel structure and surrounding soil properties. The individual behavior of circular, rectangular, and sub-rectangular tunnels subjected to seismic loadings has already been studied in the literature. In the present research, two case scenarios of circular, rectangular tunnels and four sub-rectangular shaped tunnels, with similar cross-section areas, were adopted to perform a comprehensive numerical investigation. The purpose of the study was to determine the mechanical behavior of tunnels of different shapes, depending upon seismic conditions. Analyses were performed by considering the influence of soil-lining interaction, soil parameters, and lining thickness, as well as lining rigidity. Computations were performed for no-slip and full-slip conditions. The results indicate that the tunnel shape design is of great importance when regarding the mechanical behavior of the surrounding soil. This concerns no-slip as well as full-slip soil-lining interaction, especially when the lining is subjected to seismic loading. Moreover, it is shown that changes in incremental bending moments for circular, rectangular and sub-rectangular tunnels that depend upon the soil-lining interaction conditions differ significantly.
