  2. 1. Leptin endocrinology and energy homeostasis in salmonids

    Author : Marcus Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Leptin; Leptin binding-protein; Energy homeostasis; Oncorhynchus mykiss; Salvelinus alpinus; Adiposity; Food intake; Fasting; Refeeding; Catabolism; Anorexia;

    Abstract : In salmonids, the physiological role of leptin is not completely elucidated. Nonetheless, the anorexigenic effect of leptin indicates a role in their energy homeostasis. This thesis focuses on advancing the understanding of the involvement of the leptin system in the regulation of energy homeo-stasis and food intake in teleost fish. READ MORE

  4. 2. On the Optics and Surface Physics of Liquid Crystals

    Author : Pontus Jägemalm; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; deformed helix; anchoring; short-pitch; SiO; homogeneous models; two-fold degenerate alignment; Berreman; bistable alignment; optical activity;

    Abstract : Good knowledge about optics and surface physics of liquid crystals is indispensable when utilising them for applications, such as liquid crystal displays (LCDs). However, they are also two central subjects in fundamental research on liquid crystals. READ MORE

  5. 3. Mechanisms of plant root xylem developmental plasticity in response to water deficiency and salt

    Author : Frauke Augstein; Annelie Carlsbecker; Eva Sundberg; Charles Melnyk; Malcolm Bennett; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ABA; developmental plasticity; GA; HD-ZIP III; VND; xylem; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Abstract : Plants may be exposed to a variety of different environmental conditions including water deficiency and salt, both affecting the uptake of water into the plant. Water is taken up from the soil by the roots and distributed throughout the plant via the water conducting tissue, the xylem. READ MORE

  6. 4. The Role of HoxB4 in Hematopoiesis

    Author : Ann Brun; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; adenovirus; gene transfer; knock out; HOXB4; HOXB3; homeobox genes; hematopoietic stem cells; Transcription factors; hematopoiesis;

    Abstract : HOXB4 is one of 39 members of the homeobox (HOX) family, a family of transcription factors involved in embryonic development. Several HOX transcription factors, including HOXB4, are highly expressed in hematopoietic stem cells (HSCs) but are downregulated upon differentiation towards more mature progeny cells. READ MORE
