    ABSTRACT

    Computational Modeling of Human Bicuspid Pulmonary Valve Dynamic Deformation in Patients with Tetralogy of Fallot

    Caili Li1,§, Christopher Baird2, Jing Yao3, Chun Yang4, Liang Wang5, Han Yu5, Tal Geva6, Dalin Tang5,*,7,§

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 59-59, 2019, DOI:10.32604/mcb.2019.06872

    Abstract Pulmonary valve stenosis (PVS) is one common right ventricular outflow tract obstruction problem in patients with tetralogy of Fallot (TOF). Congenital bicuspid pulmonary valve (BPV) is a condition of valvular stenosis, and the occurrence of congenital BPV is often associated with TOF. Dynamic computational models of normal pulmonary root (PR) with tri-leaflet and PR with BPV in patients with TOF were developed to investigate the effect of geometric structure of BPV on valve stress and strain distributions. The pulmonary root geometry included valvular leaflets, sinuses, interleaflet triangles and annulus. Mechanical properties of pulmonary valve leaflet were obtained from biaxial testing… More >

    ABSTRACT

    Biomechanical Implications of Bicuspid Pulmonary Valve Dynamic Deformation in Patients with Repaired Tetralogy of Fallot

    Caili Li1, Jing Yao2, Chun Yang3, Di Xu2, Liang Wang4, Dalin Tang4,5,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.1, pp. 77-78, 2019, DOI:10.32604/mcb.2019.05745

    Abstract Pulmonary valve stenosis (PVS) is one common post-operative problem in patients with tetralogy of Fallot (TOF) after repair. Congenital bicuspid pulmonary valve (BPV) is a condition of valvular stenosis, and the occurrence of congenital BPV is often associated with TOF. Compared with the biomechanical simulation model of the bicuspid aortic valve, the BPV is often neglected. In this study, we developed a dynamic biomechanical model of a simulated normal pulmonary root (PR) with tri-leaflet and a model of simulated PR with BPV in patients with repaired TOF in order to describe the effect of geometric structure with BPV on the… More >

    Transgenic wheat plants resistant to herbicide BASTA obtained by microprojectile bombardment

    MARIANA N. MELCHIORRE, HERNÁN R. LASCANO, VICTORIO S.TRIPPI

    BIOCELL, Vol.26, No.2, pp. 217-223, 2002, DOI:10.32604/biocell.2002.26.217

    Abstract Wheat (Triticum aestivum) transgenic plants of an important commercial cv (Oasis) was obtained with an efficient and short procedure. First, the optimum conditions for the embriogenic calli generation from inmature embryos with a high regeneration percentage were established. The transformation of calli was performed by high velocity microprojectile bombardment, using the pAHC25 plasmid, which contains the reporter gene β-glucuronidase (GUS) and the selectable BAR gene which confers resistance to the herbicide Basta. The transformations were confirmed by β-glucuronidase assay activity, PCR and Southern blot analysis. The efficiency of this procedure was high and similar to other reports in which “model”… More >

    Somatic embryogenesis induction from immature embryos of Sorghum bicolor L. (Moench)

    Espinoza-Sánchez EA1, YA Sánchez-Peña2, JA Torres-Castillo3, EA García-Zambrano2, JE Treviño Ramírez2, F Zavala-García2, SR Sinagawa-García2

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 105-112, 2018, DOI:10.32604/phyton.2018.87.105

    Abstract In this study, we established an in vitro regeneration system from immature embryos of four varieties of Sweet Sorghum with biotechnological potential. A total of 17 treatments were assesses in the induction of somatic embryogenic calli. We analyzed the effect of Murashige y Skoog media supplemented with different concentrations of plant growth regulators such as auxins and cytokinins. The callus induction response was evaluated using three immature embryos development stages and based on the number of embryos with callus induction. Different responses were observed in the embryos depending of the embryo age, culture condition, media composition and variety. The results… More >

    Antifungal Activity of Schinifoline Against Candida Albicans in Caenorhabditis Elegans

    Chengjie Shu1, Mengli Zhang1, Weiming Zhang1, Shihong Ma1, Guoqing Chen2 and Baojun Shi1,*

    Phyton-International Journal of Experimental Botany, Vol.88, No.3, pp. 317-324, 2019, DOI:10.32604/phyton.2019.07766

    Abstract Zanthoxylum schinifolium has been used as spices and traditional medicine in China for hundreds of years. A variety of active substances have been isolated from Zanthoxylum schinifolium using biological and chemical techniques. Among these substances, the effect of schinifoline has gradually attracted much attention. Candida albicans is one of the most common pathogens isolated from the gastrointestinal tract, vagina, and mouth in healthy individuals. In a healthy population, there are various mechanisms in host, such as the microbial flora, the epithelial barriers, and the innate immune system, that can control the presence of Candida albicans. However, when host immunity is… More >

    BIOCELL, Vol.43, No.2, pp. 81-88, 2019, DOI:10.32604/biocell.2019.06231

    Abstract The present research reports of quick and marked changes induced by plant extract of Euryops arabicus in the gene expression of 49-kDa apyrases, cytoskeletal proteins, ATPases, ADPase and amount of amino acid of pea (Pisum sativum L. var. Alaska). Pellets of cytoskeletals proteins (27000 xg) were probed with anti-apyrase antibody, biotinylated anti-rat, actin and alpha and beta-tubulin for Western blotting. ATPase and ADPase activities were determined based on the hydrolytic efficacy of adenine triphosphate and adenine diphosphate. By 72 hours, the abundance of apyrases, cytoskeletal proteins and amount of amino acid in pellets of 27000 xg of germinated pea seeds… More >

    Influences of ascorbic acid and gibberellic acid in alleviating effects of salinity in Petunia under in vitro

    Krupa-Małkiewicz M1, B Smolik2, M Sędzik2

    Phyton-International Journal of Experimental Botany, Vol.88, No.1, pp. 15-23, 2019, DOI:10.32604/phyton.2019.04670

    Abstract Salinity is one of the abiotic stresses that limits the growth and productivity of many crops. A possible survival strategy for plant under saline conditions is to use compounds that could minimize the harmful effects of salt stress on the plant development. The objective of the presented study was to investigate the effect of exogenous ascorbic acid (ASA) with or without gibberellic acid (GA3) on key growth and biochemical parameters in two petunia cultivars ‘Prism Rose’ and ‘Prism White’ under saline (150 mM NaCl) and non-saline in vitro condition. Nodal cutting with an axillary buds were used as explants. Application… More >

    Exact Solutions of the Cubic Duffing Equation by Leaf Functions under Free Vibration

    Kazunori Shinohara1

    CMES-Computer Modeling in Engineering & Sciences, Vol.115, No.2, pp. 149-215, 2018, DOI: 10.3970/cmes.2018.02179

    Abstract Exact solutions of the cubic Duffing equation with the initial conditions are presented. These exact solutions are expressed in terms of leaf functions and trigonometric functions. The leaf function r=sleafn(t) or r=cleafn(t) satisfies the ordinary differential equation dx2/dt2=-nr2n-1. The second-order differential of the leaf function is equal to -n times the function raised to the (2n-1) power of the leaf function. By using the leaf functions, the exact solutions of the cubic Duffing equation can be derived under several conditions. These solutions are constructed using the integral functions of leaf functions sleaf2(t) and cleaf2(t) for the phase of a trigonometric… More >

    ABSTRACT

    Modelling Dynamic Behaviour of Thermally Bonded Bicomponent Fibre Nonwovens

    Emrah Demirci, Memi AY Acar, Behnam Pourdeyhimi, Vadim V.Silberschmidt

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.17, No.1, pp. 17-19, 2011, DOI:10.3970/icces.2011.017.017

    Abstract Nonwovens are polymer-based engineered textiles having randomly distributed fibres bonded together with mechanical, thermal or chemical techniques. This paper focuses on thermally bonded nonwoven fabrics manufactured with bicomponent fibres. Such fibres have a core/sheath structure, with a material of the inner region - core - having a higher melting temperature than that of the surface region (sheath). During the bonding of these fibres, a hot calender with an engraved pattern contacts a fibre web causing the sheath part of fibres to melt; the latter acts as an adhesive while the fibres' core part remains fully intact. As a result of… More >
