  1. 1. Effect of surface characteristics on cellular adherence and activity

    Författare :Marjan Dorkhan; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

    Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER

  3. 2. Interactions between Malignant Keratinocytes and Fibroblasts : Studies in Head and Neck Squamous Cell Carcinoma

    Författare :Malin Hakelius; Daniel Nowinski; Bengt Gerdin; Kristofer Rubin; Avni Abdiu; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coculture; extracellular matrix; interleukin-1 alpha; tumor stroma; differential gene regulation; innate response; Plastic Surgery; Plastikkirurgi;

    Sammanfattning : Carcinoma growth requires a supportive tumor stroma. The concept of reciprocal interactions between tumor and stromal cells has become widely acknowledged and the connective tissue activation seen in the malignant process has been likened to that of a healing wound. LÄS MER

  4. 3. Oral mucosa keratinocytes and their exosomes for epithelial tissue regeneration

    Författare :Sebastian Sjöqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Early tumors, including high grade dysplasia and intramucosal invasive cancer, of the esophagus can today be removed using endoscopic resection, often using a technique called endoscopic submucosal dissection (ESD). This treatment is better tolerated and has considerably less mortality and morbidity compared to conventional, more invasive surgery, which usually entails esophagectomy. LÄS MER

  5. 4. Aldehyde toxicity in human oral epithelium

    Författare :Jan Anders Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Oral epithelium; cell cultures; toxicity; transformation; aldehydes; thiols; ADH3;

    Sammanfattning : Human oral epithelium is an established target for aldehyde toxicity, including from usage of tobacco, intake of foods and fluids, leaching of dental materials, and from mouth inhalation of aldehydes in the work environment. Following establishment of culture/exposure protocols for oral cell cultures, toxicity mechanisms and risk of malignant transformation from aldehyde exposure was investigated, including the metabolic defense offered by alcohol dehydrogenase 3 (ADH3) against formaldehyde toxicity.

  7. 5. Studies on Vitamin A Signaling in Psoriasis : A Comparison Between Normal and Lesional Keratinocytes

    Författare :Teresa Karlsson; Jan Öivind Moskaug; Uppsala universitet; []
    Nyckelord :Medical sciences; Psoriasis; vitamin A; retinoids; retinoid receptor; differentiation; keratinocyte; skin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

    Sammanfattning : Vitamin A and metabolites (retinoids) are crucial for normal epidermal maturation. Physiological effects are mediated by retinoic acid (RA) that activates nuclear retinoic acid receptors (RARs) in complexes with retinoid X receptors (RXRs), resulting in altered gene transcription.Psoriasis is a common disease with unknown etiology.
