  3. 17. Mechanical optimization of orthopaedic bone screw constructs

    Författare :Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. LÄS MER

  4. 18. Evaluation of Biomarker Responses in Fish : with Special Emphasis on Gill EROD Activity

    Författare :Carin Andersson; Jan Örberg; Björn Brunström; Lars Förlin; Uppsala universitet; []
    Nyckelord :Biology; three-spined stickleback; biomarker; EROD; ethynylestradiol; gill; vitellogenin; spiggin; CYP1A inducers; humic substances; sperm quality; biomonitoring; Biologi;

    Sammanfattning : Many chemicals present in the aquatic environment can interfere with physiological functions in fish. Exposure to chemicals can be revealed by the use of biomarkers. Induction of 7-ethoxyresorufin O-deethylase (EROD) activity is a commonly used biomarker for exposure to CYP1A inducers such as dioxins and polyaromatic hyrdrocarbons. LÄS MER

  5. 19. Endoglucanase and Mannanase from Blue Mussel, Mytilus edulis: Purification, Characterization, Gene and Three Dimensional Structure

    Författare :Bingze Xu; Folke Tjerneld; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; Bioengineering; Bioteknik; Surface Biotechnology; ytbioteknik;

    Sammanfattning : Two polysaccharide-degrading enzymes (endo-1,4-D-glucanase and β-mannanase) from blue mussel, Mytilus edulis, have been purified to homogeneity using a combination of several chromatographic steps. Each enzyme has been characterized with regard to its molecular weight, isoelectric point, pH and temperature stability, pH and temperature optimum and substrate specificity. LÄS MER

  7. 20. Analysis of different forms of locomotor behavior in lamprey

    Författare :Salma Sanzida Islam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Motor coordination; undulatory locomotion; postural corrections; spinal cord damage; lamprey;

    Sammanfattning : The ability to locomote, that is move actively in space, is characteristic of the animal kingdom. Many species are capable of different forms of locomotion. They include forward and backward locomotion, fast and slow progression, etc. LÄS MER
