  1. 1. Photosynthetic water oxidation : the function of two extrinsic proteins

    Författare :Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; Plant physiology; Växtfysiologi;

    Sammanfattning : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. LÄS MER

  3. 2. Pancreatic Growth and Secretion. An Experimental Study on Growth Factors in Rat and Mouse

    Författare :Claes Hjalmarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; PBD; insulin; B-cells; bile; pancreatic cancer; intestine; secretion; pancreas; proliferation; tyrphostins; CCK; epidermal growth factor; transforming growth factor alpha; cancerology; Cytologi; onkologi; cancer; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The pancreas is a central organ in the digestion of food as well as in glucose metabolism. Its two major functions are exocrine and endocrine secretion. LÄS MER

  4. 3. Mineral element contents in drinking water - aspects on quality and potential links to human health

    Författare :Ingegerd Rosborg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Naturvetenskap; Natural science; water treatment effects; hair concentrations; pH; magnesium; calcium; bicarbonate; drinking water; minerals;

    Sammanfattning : Mineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. LÄS MER

  5. 4. Effects of Total Parenteral Nutrition on the Exocrine and Endocrine Pancreas. An Experimental Study

    Författare :Bo-Guang Fan; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; TPN; Parotid glands; Lysosomal enzyme; Insulin; Hypotrophy; Hyperlipidemia; Food passage; Endocrine pancreas; Cholecystokinin; Exocrine pancreas; traumatology; Kirurgi; ortopedi; traumatologi; Gastro-enterology; Gastroenterologi;

    Sammanfattning : During total parenteral nutrition (TPN) adequate nutrition is provided intravenously and the enteral route is bypassed. The integrity of the gastrointestinal (GI) tract, however, is dependent on the passage of food through it. This thesis deals with the effects of TPN on the pancreas and the parotid glands. LÄS MER

  7. 5. Developmental and methodological aspects of intestinal and pancreatic function in pigs and rats

    Författare :Klas Rådberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macromolecule; endocytosis; FITC-dextran; secretion; mucosa; CCK; pancreas; disaccharidase; intestinal permeability; lectin; morphometry; Animal physiology; Djurfysiologi;

    Sammanfattning : The gastrointestinal tract has two opposing functions; to effectively absorb nutrients and to act as a safety barrier against hazardous substances in the environment. After birth these functions develops gradually. LÄS MER
