  1. 1. Biomaterials and Hemocompatibility

    Författare :Anna E. Engberg; Kristina Nilsson Ekdahl; Peter Zipfel; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement; Coagulation; Whole blood; Biomaterials; Polymers and Hemocompatibility; Immunology; Immunologi; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Biomaterials are commonly used in the medical clinic today; however, artificial materials can activate the cascade systems in the blood (complement-, coagulation-, contact- and fibrinolytic systems) as well as the platelets to various degrees. When an artificial surface comes in contact with blood, plasma proteins will be adsorbed to the surface within seconds. LÄS MER

  3. 2. Hemocompatibility of materials for use in prosthetic heart valves

    Författare :Yanqi Yang; Eric G. Butchart; Linköpings universitet; []
    Nyckelord :Heart valve prosthesis; mechanical heart valves; bioprosthetic heart valves; biomaterials; hemocompatibility; blood-material interaction; in vivo test; MEDICINE; MEDICIN;

    Sammanfattning : Thromboembolism (valve thrombosis and systemic embolism) is the main drawback of mechanical heart valve prostheses. The patients carrying these valves have to be subjected to life-long anticoagulant therapy to reduce thromboembolism. LÄS MER

  4. 3. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Författare :Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. LÄS MER

  5. 4. Oxidized Cladophora nanocellulose derivatives : Functionalization towards biocompatible materials

    Författare :Igor Rocha; Jonas Lindh; Natalia Ferraz; Albert Mihranyan; Maria Strömme; Eva Malmström Jonsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cladophora nanocellulose; TEMPO oxidation; periodate oxidation; sulfonation; cellulose beads; surface properties; biomaterials; cell studies; hemocompatibility;

    Sammanfattning : Nanocellulose is a promising candidate for biomedical applications because of its enhanced mechanical properties, increased surface area and greater porosity compared to bulk cellulose.This thesis investigates the functionalization of Cladophora nanocellulose and evaluates the influence of these modifications on physicochemical properties and biocompatibility of the material.

  7. 5. Vascular Interactions in Innate Immunity and Immunothrombosis: : Models of Endothelial Protection

    Författare :Sofia Nordling; Peetra Magnusson; Paul Kubes; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endothelial cells; Thrombosis; Innate immunity; Immunothrombosis; Thromboinflammation; Immunologi; Immunology;

    Sammanfattning : The phenomenon known as immunothrombosis has garnered increased attention over the last few years. Much work has been done to characterize the cross talk between hemostasis and the innate immune system. LÄS MER
