  1. 1. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Författare :Karin Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

    Sammanfattning : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. LÄS MER

  3. 2. Oxidation of marine oils during in vitro gastrointestinal digestion and its effects on stress in human intestinal Caco-2 cells

    Författare :Cecilia Tullberg; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lipid oxidation; human digestive fluids; LC n-3 PUFAs; Caco-2 cells; marine oils; HNE; MDA; in vitro digestion; HHE; gastrointestinal; aldehydes;

    Sammanfattning : Marine oils are attracting public interest due to the preventive effects, e.g., on inflammation, which are linked to the long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs). However, LC n-3 PUFAs are highly susceptible to oxidation, which could interfere with their positive effects. LÄS MER

  4. 3. Studies of α-synuclein Oligomers-with Relevance to Lewy Body Disorders

    Författare :Therese Fagerqvist; Martin Ingelsson; Joakim Bergström; Lars Lannfelt; Michael G Schlossmacher; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Parkinson´s disease; Lewy body dementia; Oligomer; Monoclonal antibody; Immunotherapy; Reactive aldehydes; Medical Science; Medicinsk vetenskap;

    Sammanfattning : The protein alpha-synuclein (α-synuclein) accumulates in the brain in disorders such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB). It is believed that the monomeric form of α-synuclein can adopt a partially folded structure and start to aggregate and form intermediately sized oligomers or protofibrils. LÄS MER

  5. 4. Bridging McMurry and Wittig in One-Pot : Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes

    Författare :Juri Mai; Sascha Ott; Christian Müller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonyl olefination; reductive aldehyde coupling; stereoselective; organophosphorus; phosphaalkene; phosphanylphosphonate; Wittig; Horner-Wittig; Horner-Wadsworth-Emmons; McMurry; Kemi; Chemistry;

    Sammanfattning : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.

  7. 5. Selective conversion of alcohols to aldehydes over metal oxide catalysts

    Författare :Mariano Massa; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. LÄS MER
