    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER

    Författare :Anne Therese Lauvrud; Paul J. Kingham; Rebecca Wiberg; Peyman Kelk; Maria Brohlin; Susanna Kauhanen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue-derived stem cells; liposuction; oncological safety; xenofree growth medium; Human Anatomy; anatomi;

    Sammanfattning : Fat grafting has become an established method in plastic surgery for treating soft tissue defects. The results for survival of the fat being transplanted is unpredictable and supplementation of the graft with the Stromal Vascular Fraction (SVF) or cultures Adipose tissue-derived stem cells (ASCs) can enhance graft viability.

    Sammanfattning : Despite the innate regenerative capabilities of bone tissue, self-repair is impaired when an injury exceeds the critical size threshold because of trauma, congenital, or pathological conditions. Autologous transplantation is the gold standard to reconstruct large bone defects. LÄS MER
