  1. 11. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

    Författare :Gabriel Barbosa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

    Sammanfattning : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. LÄS MER

  3. 12. The evaluation, preoperative and operative aspects of abdominal wall reconstruction for giant ventral hernia

    Författare :Leonard Clay; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : BACKGROUND: The optimal method for surgical repair of giant ventral hernia remains to be determined. Different concepts for reinforcement have been used, which have decreased the risk for recurrence. LÄS MER

  4. 13. Multistage gearboxes : vibration based quality control

    Författare :Johan Wändell; Hans Bodén; Ulf Carlsson; Kjell Ahlin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. LÄS MER

  5. 14. Host-Virus Interactions in Asthma and COPD

    Författare :Cristopher McCrae; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; COPD; Exacerbation; Virus; Interferon;

    Sammanfattning : Asthma and chronic obstructive pulmonary disease (COPD) are associated with periods of worsened symptoms, known as exacerbations. Severe exac-erbations can result in hospitalisation, irreversible decline of the disease and sometimes death. Thus, exacerbations are a major cause of morbidity, mortality and healthcare cost.

  7. 15. Effects of nitrogen dioxide on airway responsiveness in allergic asthma

    Författare :Victoria Strand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :air pollution; nitrogen dioxide; asthma; allergy; airway responsiveness; pulmonary function; eosinophils; particulates; repeated exposure;

    Sammanfattning : Asthma is one of the most common chronic diseases in the industrialized world and its prevalence is increasing. Clinical symptoms of airway obstruction and bronchial hyper responsiveness can be induced by specific agents, such as allergens and non-specific stimuli, such as cold air and irritants. LÄS MER
