  1. 1. The cross-talk of iron and ascorbate -Complexation and intracellular regulation of transport in human enterocytes

    Author : Nathalie Scheers; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NRAMP2; ascorbate; ferroportin; ferritin; iron; SVCT1; DCYTB;

    Abstract : Iron deficiency is a serious health issue in developing countries and also in vulnerable groups of the industrialized world. There are several ways to address this issue. The present approach was to learn more about the basic mechanisms of iron uptake in the presence of ascorbate, one of the best enhancers of iron absorption. READ MORE

  2. 2. Ascorbate in the ocular lens

    Author : Vino C Jr Mody; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Purpose: First, we intended to establish a method for sample preparation for measurement of ascorbate in whole rat and guinea pig lenses utilizing ultrafiltration and high performance liquid chromatography with ultraviolet radiation detection. Then, we aimed to investigate whether, in the albino rat, lens ascorbate concentration depends on solid dietary intake. READ MORE

  3. 3. The xanthophyll cycle, its enzymes, pigments and regulation

    Author : Marie Eskling Carlsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeaxanthin; xanthophyll cycle; violaxanthin de-epoxidase; thylakoid; spinach; regulation; purification; pigments; photoprotection; pH dependence; ascorbate; light stress; Plant biochemistry; Växtbiokemi;

    Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

  4. 4. Role of intermediate filaments and expression of GFAP and S-100 in astrocytes

    Author : Mei Ding; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Astrocytes; Gliosis; Kainic acid; Transgenic mouse; S-100; GFAP; Vimentin; RVD regulatory volume decrease ; Taurine; Glutamine; Ascorbate; Glucose;

    Abstract : Astrocytes participate in a variety of important physiologic and pathologic processes in the central nervous system (CNS). One of the most remarkable characteristics of astrocytes is their vigorous response to CNS injuries. READ MORE

  5. 5. Ultraviolet radiation cataract development and ascorbate supplementation

    Author : Vino C Jr Mody; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Cataract is the major cause of blindness in the world, and long-term solar ultraviolet radiation (UVR) is a major risk factor. The pathogenesis of UVRinduced cataract is studied in various animal models and cell systems. READ MORE
