  1. 36. Studies on antioxidant and lipid lowering effects on human microcirculation

    Författare :Qing Lu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Microcirculation; oxidative stress; antioxidant; smoking. hypercholesterolemia; diabetes; vitamin C; Nacetylcysteine; lipid lowering; capillary blood flow velocity; post reactive hyperemia; endothelial function.;

    Sammanfattning : In previous work from this laboratory, vital microscopy was successfully used to study rnicrocirculatcry effects of hypercholesterolemia in a rabbit model. Hypercholesterolemia caused a dramatic depression of the blood flow velocity in the conjunctiva microvessels of the rabbits. LÄS MER

  3. 37. Functional characterization of cytosolic and mitochondrial thioredoxin reductases

    Författare :Ivan Nalvarte; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Thioredoxin; thioredoxin reductase; reactive oxygen species; mitochondria; differentiation; redox signaling; ubiquinone; cytochrome c; selenium; selenoprotein.;

    Sammanfattning : Mammalian thioredoxin reductases (TrxRs) are homodimeric selenoproteins belonging to the nucleotide oxidoreductase family. They contain a C-terminal penultimate selenocysteine residue, which is kept reduced by the N-terminal redox active site, CVNVGC, of the adjacent subunit. LÄS MER

  4. 38. The human antimicrobial protein hCAP18/LL37 in wound healing and cell proliferation

    Författare :Johan Heilborn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Innate immunity; antimicrobial peptides; LL-37; epithelial cell; keratinocytes; proliferation; reepithelialization; wound healing; tissue repair; angiogenesis; tumor growth; vitamin D;

    Sammanfattning : Epithelia constitute the principal barriers separating the host and the potentially injurious environment, and defence of this interface is therefore essential. Antimicrobial peptides are key effector molecules of the innate immune system. LÄS MER

  5. 39. α-tocopherol and β-carotene in forages and their utilisation by dairy cows in organic production

    Författare :Hanna Lindqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : There are large variations in α-tocopherol (vitamin E) and β-carotene (pro-vitamin A) concentrations in forages. α-Tocopherol and β-carotene are antioxidants and important for the health and fertility of cows. LÄS MER

  7. 40. Pre-harvest factors affecting quality and shelf-life in raspberries and blackberries (Rubus spp. L.)

    Författare :Liaqat Ali; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Fruit including berries have been demonstrated to exhibit a broad spectrum of benefits including protection against cardiovascular, neurological, and lung diseases, as well as having antioxidant, antimicrobial, anti-inflammatory, anti- diabetic and anti-aging properties. These protective effects are reported to be due to their high content of bioactive compounds, such as vitamin C, vitamin E, phenolic acids, ellagitannins, flavonoids and carotenoids. LÄS MER
