    QIAN LI1,#, SHUNPENG ZHU1,#, MINGXIAN ZHU2, FANG WANG1,*, JINHUA ZHOU1,*

    Oncology Research, DOI:10.32604/or.2025.062539

    Abstract Objectives: Our previous research demonstrated that SIC-19, an innovative inhibitor of salt-inducible kinase 2 (SIK2), effectively reduces SIK2 protein levels through the ubiquitin-proteasome pathway and exhibits synthetic lethal effects with poly ADP-ribose polymerase (PARP) inhibitors in ovarian cancer. However, the role of SIC-19 in triple-negative breast cancer (TNBC) and pancreatic cancer (PC) remains poorly defined. This study aims to investigate whether SIC-19 combined with PARP inhibitors can induce synthetic lethal effects in TNBC and PC. Methods: Cell lines with high SIK2 expression were identified through Western blot analysis. The combination’s impact was evaluated using Cell… More >

    Jiahao Liu1,#, Xinyu Zhang1,#, Huiwei Wang1, Yupeng Li1, Shan Jin1, Guanxian Qiu1, Ce Sun1,2,*, Haiyan Tan1, Yanhua Zhang1,2,*

    Journal of Renewable Materials, DOI:10.32604/jrm.2025.02025-0042

    Abstract In recent years, degradable materials to replace petroleum-based materials in preparing high-performance foams have received much research attention. Degradable polymer foaming mostly uses supercritical fluids, especially carbon dioxide (Sc-CO2). The main reason is that the foams obtained by Sc-CO2 foaming have excellent performance, and the foaming agent is green and pollution-free. In current research, Poly (butylene adipate-co-terephthalate) (PBAT), poly (lactic acid) (PLA), and other degradable polymers are generally used as the main foaming materials, but the foaming performance of these degradable polyesters is poor and requires modification. In this work, 10% PLA was added to PBAT to… More >

    Hydrogen-Methane Blend Storage in Depleted Reservoirs: An Option for Reusing Decommissioned Offshore Platforms

    Anna Chiara Uggenti1, Giorgio Rech2, Raffaella Gerboni2,*, Gianmario Ledda2, Amedeo Aliberti1, Claudia Vivalda3, Emanuela Bruno2, Andrea Carpignano2

    FDMP-Fluid Dynamics & Materials Processing, DOI:10.32604/fdmp.2025.062347

    Abstract The paper presents an innovative approach to studying the reuse of a decommissioned natural gas production platform for the seasonal storage and extraction of a hydrogen-methane (H2-CH4) mixture from a depleted reservoir. The reuse plan involves removing outdated equipment from the platform’s decks while retaining essential components such as wellheads and separators. Exploiting a depleted reservoir for the injection of an H2-CH4 mixture requires a thorough understanding of its specific characteristics. This paper focuses on the engineering approach adopted in the basic design phase for such a conversion, providing recommendations and HSE guidelines. Given the hazardous… More >

    Energy Engineering, DOI:10.32604/ee.2025.062765

    Abstract Considering the special features of dynamic environment economic dispatch of power systems with high dimensionality, strong coupling, nonlinearity, and non-convexity, a GA-DE multi-objective optimization algorithm based on dual-population pseudo-parallel genetic algorithm-differential evolution is proposed in this paper. The algorithm is based on external elite archive and Pareto dominance, and it adopts the cooperative co-evolution mechanism of differential evolution and genetic algorithm. Average entropy and cubic chaotic mapping initialization strategies are proposed to increase population diversity. In the proposed method, we analyze the distribution of neighboring solutions and apply a new Pareto solution set pruning approach.… More >
