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

    University dissertation from Växjö : Linnaeus University Press

    Author : Emil Fridolfsson; Linnéuniversitetet.; [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 : Tiamin (vitamin B1) är nödvändigt för flera livsuppehållande processer i cellerna hos det stora flertalet organismer, t.ex. vid omvandling av näring till energi. Vitaminet fungerar också som en antioxidant och är viktigt för korrekt nervfunktion. READ MORE

  2. 2. 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; Uppsala universitet.; [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.

  3. 3. Thiamine dynamics in the pelagic food web of the Baltic Sea

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Peter Sylvander; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marin ekologi; Marine Ecology; Thiamine; Vitamin B1; Baltic Sea; M74;

    Abstract : Thiamine (vitamin B1) is involved in several basal metabolic processes. It is an essential compound for many organisms and in aquatic systems it is mainly produced by phytoplankton and prokaryotes and transferred to higher trophic levels through grazing and predation. READ MORE

  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; Uppsala universitet.; [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

    Author : Huanmei Zhang; Lund University.; Lunds universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Antioxidants; Avenanthramides; Biological value; Iron absorption; Fatty acids; Processing; Minerals; Vitamins; Storage; Stability; Nutritional properties; Oats; Beverage; Bioteknik;

    Abstract : The cholesterol-lowering effects of oats have led to an increasing interest in them on the food market. Liquid oats has emerged as a new way of consuming oats and has become a commercial product. READ MORE
