    Sammanfattning : Alzheimer’s disease is an incurable neurodegenerative disorder linked to the amyloid β (Aβ) peptide, a 38-43 residue peptide. The detailed molecular disease mechanism(s) is (are) unknown, but oligomeric Aβ structures are proposed to be involved. LÄS MER

  2. 17. Bioinformatic protein family characterisation

    Författare :Joel Hedlund; Bengt Persson; Jaap Heringa; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Biological research is necessary; not only to further our understanding of the processes of life, but also to combat disease, hunger and environmental damage.Bioinformatics is the science of handling biological information. It entails integrating, structuring and analysing the ever-increasing amounts of available biological data. LÄS MER

  3. 18. Structure and function studies on nrdB group I intron from bacteriophage T4

    Författare :Ann-Sofie Sjögren; Gerhart Wagner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The nrdB gene of bacteriophage T4 contains a group I intron which is autocatalytic in water solutions containing salts. The group I intron self-splicing reaction consists of two consecutive transesterfication steps. The first step is the attack of an external guanosine on phosphor at the 5'-splice site. LÄS MER

  4. 19. Cereal- and Microbial Phytases. Phytate Degradation, Mineral Binding and Absorption

    Författare :Maria Türk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mineral binding; iron absorption; cereals; phytate degradation; phytase; dietary phytases; S cerevisiae; A niger;

    Sammanfattning : Cereal foods contain large amounts of phytate (myo-inositol hexaphosphate; IP6), which is the major storage form of phosphorus, in the plant. IP6 possesses a high potential for chelating minerals, such as Fe 2+, Zn2+, Mg2+ and Ca2+. LÄS MER

  5. 20. Plant-Derived Substances and Cardiovascular Diseases : Effects of Flavonoids, Terpenes and Sterols on Angiotensin-Converting Enzyme and Nitric Oxide

    Författare :Ingrid Persson; Rolf G.G. Andersson; Lars Bohlin; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Diet has for many years been known to play a key role in the development of chronic diseases. There are clear associations between consumption of vegetables, fruits and berries, and risk of cardiovascular diseases, the number one cause of death in the world. LÄS MER
