    Abstract RPA3 (Replication Protein A3) (14 kD) is a part of the canonical heterotrimeric replication protein A complex (RPA/RP-A). This study aimed to explore the functional role of RPA3 and the mechanisms of its dysregulation in breast cancer. Data from the Cancer Genome Atlas (TCGA)-breast cancer patients and GSE75688 were utilized for gene expression and survival analysis. Breast cancer cell lines MDA-MB-231 and SK-BR-3 were used for in-vitro cell studies. Clonogenic assay and immunofluorescent staining of γ-H2AX were performed to examine radiation-induced cytotoxicity. Systemic correlation analysis was performed to identify potential transcription factors (TFs) regulating RPA3 expression. ChIP-qPCR and dual-luciferase assay… More >

    Abstract Oxidative stress-mediated cell death in cardiomyocytes contributes to the development of atrial fibrillation. However, the detailed mechanisms are still unclear. In the present study, we established atrial fibrillation models in mice. The cardiomyocytes were isolated from atrial fibrillation mice and normal mice and were cultured in vitro, respectively. The results showed that cell proliferation and viability in cardiomyocytes with atrial fibrillation were significantly lower than the cells from the normal mice. Consistently, atrial fibrillation cardiomyocytes were prone to suffer from apoptotic cell death. Also, the oxidative stress and ferroptosis-associated signatures were significantly increased in atrial fibrillation cardiomyocytes compared to normal… More >

    Abstract Non-small cell lung cancer (NSCLC) cells intake and consume glucose at high efficiency by aerobic glycolysis to maintain robust cell growth and resist cell death. MicroRNAs (miRNAs) have been known to play pivotal roles in NSCLC development partly through mediating glycolysis. However, only a few miRNAs have been experimentally confirmed as critical regulators of glycolysis in NSCLC. TCGA datasets were analyzed to screen for differentially expressed miRNAs between NSCLC and normal tissues. The function of miR-1294-5p was determined in NSCLC cells by cell proliferation, glucose uptake, lactate release, and Extracellular Acidification Rate (ECAR) assays. The target of miR- 1294-5p was… More >

    Abstract Esophageal cancer is the second most common type of cancer after lung carcinoma in the state of Jammu and Kashmir (J&K). The understanding of genetics in Esophageal cancer development is poor in the state. Genome wide association studies (GWAS) has proved to be unsurpassed tool in identification of new loci associated with different cancers. GWAS in Chinese population has identified SNP rs2294693 present in UNC5CL (UNC-5 Family C-Terminal like) to be associated with non-cardia gastric cancer. We performed a case control association study and genotyped the SNP rs2294693 using Taqman allele discrimination assay in 566 individuals (166 esophageal cancer patients… More >

    Effect of Ultraviolet Aging on the Bonding and Tensile Properties of Polymer-Cement Composite

    Zhihang Wang1,*, Jinyu Xu1,2, Xin Meng1, Conigjin Zhu1

    Journal of Renewable Materials, Vol., , DOI:10.32604/jrm.2021.014878

    Abstract In this paper, the specimens of polymer-cement composites after 1 d, 7 d, 15 d, and 30 d aging without aging and UV aging are subjected to fixed extension test and tensile test. By observing the mode of the composite in the fixed-elongation test, and measuring the elastic recovery rate, tensile strength, elongation at break, peak tensile strain, tensile toughness and pre-peak tensile toughness of the composite, the effects of UV aging on the bonding and the tensile properties of the composite were studied. And combining with scanning electron microscopy experiments, the micro-mechanism of the effect of ultraviolet aging on… More >

    Abstract Aortic valve replacement (AVR) remains a major treatment option for patients with severe aortic valve disease. Clinical outcome of AVR is strongly dependent on implanted prosthetic valve size. Fluid-structure interaction (FSI) aortic root models were constructed to investigate the effect of valve size on hemodynamics of the implanted bioprosthetic valve and optimize the outcome of AVR surgery. FSI models with 4 sizes of bioprosthetic valves (19 (No. 19), 21 (No. 21), 23 (No. 23) and 25 mm (No. 25)) were constructed. Left ventricle outflow track flow data from one patient was collected and used as model flow conditions. Anisotropic Mooney–Rivlin… More >

    Mycorrhizal Fungal Effects on Growth, Antioxidant Capacity, and Medicine Quality of Paris polyphylla var. yunnanensis

    Nong Zhou1,2, Lingfeng Xu1, Min Yang2, Dongqin Guo1, Qiuxia Gan, Jingjing Zhao1,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.014858

    Abstract A field experiment was conducted to determine the effects of two commercial strains composed of mulple arbuscular mycorrhizal fungi (AMF) species on plant growth, antioxidant capacity, and medicine quality of Paris polyphylla var. yunnanensis in three subtropical soils from Wanzhou, Anshun and Baoshan in fields. The results showed that AMF inoculation enhanced the fungal colonization rate and activities of both succinate dehydrogenase and alkaline phosphatase, thereby, enhancing the mycorrhizal viability of P. polyphylla var. yunnanensis. The concentrations of photosynthetic pigments (chlorophyll a, b, a+b and carotenoids), soluble sugar, soluble protein and photosynthetic capacity were higher in AMF-inoculated plants than in… More >

    Abstract The tomato (Solanum lycopersicum L.) is one of the world’s most important vegetable crops. Still, phytopathogenic bacteria affect the yield and quality of tomato cultivation, like Agrobacterium tumefeciens (At), Clavibacter michiganensis subsp. michiganensis (Cmm), Pseudomonas syringae pv. tomato (Pst), Ralstonia solanacearum (Rs), and Xanthomonas axonopodis (Xa). Synthetic chemical products are used mostly on disease plant control, but overuse generates resistance to bacterial control. This study aimed to evaluate the in vitro antibacterial activity of the ethanolic extract of Moringa oleifera Lam. leaves against At, Cmm, Pst, Rs, and Xa, as well as information about this plant species’ chemical composition. Antibacterial… More >

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2021.013775

    Abstract This study scrutinized the possibility of finding toxicant or deterrent plant metabolites against the dry wood termite Incisitermes marginipennis (Latreille). Plant deterrent agents act as repellents or antifeedants to prevent wood decay and increase its useful life. The potential of the tree Caesalpinia coriaria (Fabaceae) as a biological source of molecules with deterrent effects against the dry wood termite was assessed by a phytochemical fractionation guided by repellence and antifeedant activities. The gas chromatography-mass spectrometry analysis of the leaf essential oil showed geraniol to be one of the major components and its repellent and antifeedant effects were determined. Geraniol had… More >

    Experimental and Numerical Study on the Shear Strength and Strain Energy of Rock Under Constant Shear Stress and Unloading Normal Stress

    Tantan Zhu1, Da Huang2,3,*, Jianxun Chen1, Yanbin Luo1, Longfei Xu1

    CMES-Computer Modeling in Engineering & Sciences, Vol., , DOI:10.32604/cmes.2021.014808

    Abstract Excavation and earth surface processes (e.g., river incision) always induce the unloading of stress, which can cause the failure of rocks. To study the shear mechanical behavior of a rock sample under unloading normal stress conditions, a new stress path for direct shear tests was proposed to model the unloading of stress caused by excavation and other processes. The effects of the initial stresses (i.e., the normal stress and shear stress before unloading) on the shear behavior and energy conversion were investigated using laboratory tests and numerical simulations. The shear strength of a rock under constant stress or under unloading… More >
