  1. 1. Thiamin (vitamin B1) in the aquatic food web

    University dissertation from Växjö : Linnaeus University Press

    Author : Emil Fridolfsson; Samuel Hylander; Michael T. Brett; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton; zooplankton; thiamin; transfer; food web dynamics; micronutrient; vitamin; Baltic Sea; community composition; M74; salmon; B1; växtplankton; djurplankton; tiamin; överföring; födoväv; mikronäringsämne; vitamin; Östersjön; B1; lax;

    Abstract : Thiamin (vitamin B1) is required for several life-sustaining processes in most organisms and cells, e.g. in the conversion of food to energy. It also serves as an antioxidant and is important for proper nerve signaling. READ MORE

  3. 3. Dynamics of astaxanthin, tocopherol (Vitamin E) and thiamine (Vitamin B1) in the Baltic Sea ecosystem Bottom-up effects in an aquatic food web

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Norbert Häubner; Pauli Snoeijs; Jon Ågren; Rhena Schumann; Markku Viitasalo; [2010]
    Keywords : Baltic Sea; carotenoids; astaxanthin; tocopherols; Vitamin E; thiamine; Vitamin B1; pelagic food web; eutrophication; M74; phytoplankton; zooplankton; sprat; Sprattus sprattus balticus; herring; Clupea harengus; salmon; Salmo salar; cod; Gadus morhua; High Performance Liquid Chromatography HPLC ; electrochemical detection ECD ;

    Abstract : The thesis combines laboratory experiments and field expeditions to study production, transfer and consumption of non-enzymatic antioxidants and thiamine in an aquatic food web. In particular, I (1) documented spatial and seasonal variation of tocopherols and carotenoids in the Baltic Sea pelagic food web, and (2) examined the effects of abiotic and biotic factors on tocopherol, carotenoid and thiamine concentrations in phytoplankton, zooplankton and fish.

  4. 4. Retinoic Acid Metabolism Blocking Agents and the Skin In vivo and in vitro Studies of the Effects on Normal and Diseased Human Epidermis

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Elizabeth Pavez Loriè; Anders Vahlquist; Hans Törmä; Marie Virtanen; Helen Håkansson; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CYP; CYP26; retinoids; vitamin A; RAMBA; metabolism; keratinocyte; epidermis; retinoid regulated genes; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Dermatology and venerology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Dermatologi och venerologi;

    Abstract : Retinoic Acid Metabolism Blocking Agents (RAMBAs) increase the endogenous levels of all-trans retinoic acid (RA) by inhibiting CYP26 enzymes. Thus they are believed to mimic the effects of retinoid treatment. Their mechanism of action and effects on vitamin A metabolism in keratinocytes are however uncertain. READ MORE

  5. 5. Nutritional Properties of Liquid Oats as Affected by Processing and Storage

    University dissertation from Lund University
