  2. 16. The expanded skin in breast reconstruction : an experimental and clinical study

    Author : Michael Olenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Tissue expansion; capsular contraction; rapid and slow expansion; mitotic activity; epidermal thickness; skin thickness; collagen diameter; skin properties; insulin-like growth factorStockholm 1995 ISB;

    Abstract : Tissue expansion has become one of the routine methods in breast reconstruction. It is a safe and easy method, which is well accepted by the patient. Clinical reports are numerous, but morphological changes are still not thoroughly investigated. READ MORE

  4. 17. Conifer embryology : a study of polar auxin transport and WOX transcription factors

    Author : Joakim Palovaara; Inger Hakman; Wolfgang Werr; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Cell and Organism Biology; Cell- och organismbiologi;

    Abstract : Plants, like animals, use endogenous signaling molecules to coordinate their own physiology and development. One such molecule in plants is the hormone auxin and recent research has implicated auxin and its polar transport, together with the WOX transcription factors, in regulating embryo patterning and development in angiosperms (flowering plants), the most diverse group of land plants.

  5. 18. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

    Author : Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. READ MORE

  6. 19. Studies on Vitamin A Signaling in Psoriasis : A Comparison Between Normal and Lesional Keratinocytes

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

    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.

  7. 20. 3D modelling of epidermal nerve fiber patterns

    Author : Konstantinos Konstantinou; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diabetic neuropathy; Anisotropy; point processes.; epidermal nerve fibers;

    Abstract : Neuropathical disorders, such as diabetic neuropathy, damage the nerve structure in the epidermis. This thesis presents statistical analyses and models for the epidermal nerve fibers (ENFs). The main objective is to improve our understanding regarding the three dimensional ENF structure and for this purpose, stochastic models are constructed. READ MORE
