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

    University dissertation from Faculty of Odontology, Malmö University

    Author : Marjan Dorkhan; Malmö University.; [2014]
    Keywords : ODONTOLOGY; ODONTOLOGI; 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;

    Abstract : After insertion of the dental implant into the jaw, the neck of the implant protruding through the mucosa (implant abutment) will be exposed to the complex environment of the mouth. This results in the formation of a conditioning protein coat (pellicle) derived from saliva and/or gingival crevicular fluid. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Malin Hakelius; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coculture; extracellular matrix; interleukin-1 alpha; tumor stroma; differential gene regulation; innate response; Plastikkirurgi; Plastic Surgery;

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Sebastian Sjöqvist; Karolinska Institutet.; Karolinska Institutet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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. READ MORE

  4. 4. Aldehyde toxicity in human oral epithelium

    University dissertation from Stockholm : Karolinska Institutet, Institute of Enviromental Medicine

    Author : Jan Anders Nilsson; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oral epithelium; cell cultures; toxicity; transformation; aldehydes; thiols; ADH3;

    Abstract : 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.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Teresa Karlsson; Uppsala universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Psoriasis; vitamin A; retinoids; retinoid receptor; differentiation; keratinocyte; skin; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; dermatologi och venereologi; Dermatology and Venerology;

    Abstract : 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.
