  2. 6. Biological aspects of synovial fluid mediated aseptic prosthesis loosening

    Author : Martin Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Aseptic loosening; synovial fluid; osteoblasts; bone resorption; IGF;

    Abstract : Aseptic prosthesis loosening is the most common reason for late failure of total hip arthroplasties. Resorption of the peri-prosthetic bone, resulting in a loose prosthesis is characteristic for aseptic loosening. READ MORE

  7. 10. Emerging tick-borne pathogens: on the ecology of multiple infections in ticks and reservoir hosts

    Author : Martin Andersson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Borrelia afzelii; ’Candidatus Neoehrlichia mikurensis’; bank vole; Myodes glareolus; multiple infection; tick-borne diseases; vector-borne diseases; competition; facilitation; qPCR;

    Abstract : Most animals will encounter several more or less severe infectious diseases during their lifetime, and simultaneous infections with more than one pathogen, or several different strains of the same pathogen, are common in natural populations. Ticks transmit a wide variety of different pathogens and can also be simultaneously infected with more than one pathogen. READ MORE
