  1. 16. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

    Författare :Anders Halldin; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

    Sammanfattning : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. LÄS MER

  3. 17. Gastric and enteric Helicobacter species in animal models and in the human colon

    Författare :Erik Sturegård; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; Mikrobiologi; bakteriologi; IL-10; Microbiology; bacteriology; virology; virologi; mykologi; hepatitis; colitis; IBD; inflammatory bowel disease; gastritis; animal model; mouse; guinea pig; Helicobacter ganmani; Helicobacter; Helicobacter pylori;

    Sammanfattning : The Gram-negative genus of Helicobacter consists of many bacterial species that colonize a wide range of animal hosts. The genus can be divided into gastric species that colonize the stomach, and enteric species that preferentially colonize the colon and biliary tree of various animal hosts. LÄS MER

  4. 18. Topical anesthesia of the tympanic membrane : an experimental animal study

    Författare :Sten-Hermann Schmidt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

    Sammanfattning : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. LÄS MER

  5. 19. Experimental Helicobacter pylori infection in an animal model

    Författare :Yi-Qian Sun; Torkel Wadström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Helicobacter pylori is a microaerophilic Gram-negative bacterium colonizing the human stomach. The prevalence of this infection is between 20-90% depending on geographic location. Comprehensive studies have shown significant relationships between H. pylori infection and chronic gastritis, peptic ulcer and gastric carcinoma. LÄS MER

  7. 20. Sustainable business model innovation in agri-firms

    Författare :Per-Ola Ulvenblad; Henrik Barth; Jonas Gabrielsson; Lena Andersson Ekelund; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agri-entrepreneur; sustainable business model innovation; business model building block; value intention; stewardship; Smart Cities and Communities; Smarta städer och samhällen;

    Sammanfattning : Background The focus of the research in the thesis is the development of sustainable business model innovation in Swedish agri-firms. There are needs on global and national levels for sustainable business model innovation in the agri-sector. More food must be produced to feed the growing world population. LÄS MER
