  2. 1. In vitro accessibility of provitamin A carotenoids in vegetables and fruits - Effects of different process and preparation methods and estimation of vitamin A activity

    Author : Ellen Hedrén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; provitamin A carotenoids; lactic acid fermentation; food matrix; cell wall degrading enzymes; vegetables; vitamin A activity; beta-carotene; red palm oil; fruits;

    Abstract : Vitamin A deficiency is a major nutritional problem in many developing countries, caused chiefly by a diet with low retinol content. The bioefficacy of provitamin A carotenoids in plant foods is claimed to be insufficient to maintain a satisfactory vitamin A status. READ MORE

  4. 2. Content and In Vitro Accessibility of Provitamin. A Carotenoids in Some Tanzanian Vegetables and Fruits Effects of Traditional Processing and Preparation, and Influence on Vitamin A Status

    Author : Generose Ishengoma Mulokozi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; sunflower oil; solar cabinet drying; women; all-trans-beta-carotene; alpha-carotene; open sun-drying; vitamin A; provitamin A carotenoids; plasma; breast milk; fruits; vegetables; red palm oil; Tanzania; beta-cryptoxanthin; pregnancy; children;

    Abstract : Vitamin A deficiency is among the major nutritional problems in Tanzania as in many developing countries. It mainly affects children and pregnant and lactating women. The basic cause of this problem is related to the diet, which contains little preformed vitamin A and plant foods with a low content and bioavailability of provitamin A carotenoids. READ MORE

  5. 3. The Long and Winding Road : Emotional Reactions during In Vitro Fertilization and Attitudes towards Cryopreserved Embryos and Oocyte Donation

    Author : Agneta Skoog Svanberg; Torbjörn Bergh; Claudia Lampic; Per Olof Janson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caring sciences; attitude; cryopreservation; discarding; disclosure; distress; emotion; gender; infertility; in vitro fertilization; oocyte donation; psychology; public; Vårdvetenskap; Caring sciences; Vårdvetenskap; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Abstract : The main aims were to investigate emotional reactions during in vitro fertilization (IVF) treatment among women and men, attitudes of IVF couples towards cryopreserved embryos and public attitudes towards various aspects of oocyte donation in Sweden. Assessments of emotional, physical and social reactions were made on a daily reaction scale and attitudes on the basis of study-specific questionnaires. READ MORE

  6. 4. Organic Electronics and Microphysiological Systems to Interface, Monitor, and Model Biology

    Author : Sebastian Buchmann; Anna Herland; Erica Zeglio; Agneta Richter-Dahlfors; Maria Asplund; KTH; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic bioelectronics; organic electrochemical transistors; conjugated polymers; microphysiological systems; in vitro cell models; Organisk bioelektronik; organiska elektrokemiska transistorer; Konjugerade polymerer; Mikrofysiologiska system; in vitro-modeller; Medicinsk teknologi; Medical Technology;

    Abstract : Biological processes in the human body are regulated through complex and precise arrangements of cell structures and their interactions. In vivo models serve as the most accurate choice for biological studies to understand these processes. However, they are costly, time-consuming, and raise ethical issues. READ MORE

  7. 5. Nutritional properties of tempe fermented whole-grain barley and oats. Influence of processing conditions on the retention and availability of iron, starch and folates

    Author : Charlotte Eklund Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro digestion; high ß-glucan oats; high amylose high ß-glucan barley; folate accessibility; glycemic response; tempe fermentation; iron availability; phytate; iron absorption; Rhizopus oligosporus;

    Abstract : This thesis aimed at evaluating the tempe fermentation process as a means to develop nutritionally improved vegetarian products from barley and oats. The work was designed to assess relationships between selection of raw material and processing conditions in correlation to nutrient content and availability. READ MORE
