  3. 7. Tabletting behaviour of aggregates : Mechanistical conception and modulation by variations in aggregate physical properties

    Författare :Barbro Johansson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Sammanfattning : The volume reduction mechanisms involved during compression of aggregates prepared from microcrystalline cellulose particles and effects of variations in their physical properties on their compression behaviour and compactability were studied in this thesis.The dominating volume reduction mechanisms during compression of aggregates prepared of MCC were deformation (bulk deformation and local deformation) parallel with densification, and generally the degree of fragmentation of the aggregates was minute.

  4. 8. Catanionic Aggregates in Gels : Prolonged Drug Release and Potential Implications for Topical Use

    Författare :Noel Dew; Erik Björk; Stefan Ulvenlund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Galenisk farmaci; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : Gels are popular dosage forms.  This topical dosage form may be advantageous compared to oral or parenteral dosage forms. Favorable rheological or bioadhesive properties of gels might provide extended contact times at the site of administration compared to aqueous solutions. LÄS MER

  5. 9. Links between Aging and Proteostasis Decline in Saccharomyces cerevisiae

    Författare :Veronica Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aging; aggregates; proteostasis; proteasome; disaggregation; peroxiredoxins; asymmetric inheritance; S. cerevisiae;

    Sammanfattning : Proteins are continuously synthesized and degraded to meet the demands of the cell. Hence, a proper balance between synthesis, folding, disaggregation and degradation is of essence to ensure cell survival. Disruption of any part of this proteostasis network may have severe consequences for cellular fitness and longevity. LÄS MER

  7. 10. Amyloid aggregates: detection and interaction

    Författare :Mahafuzur Rahman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The research on protein aggregation and amyloid formation is motivated by the fact that amyloid formation in tissue is harmful and associated with several debilitating diseases including Alzheimer’s disease (AD) and systemic amyloidosis such as transthyretin (ATTR) amyloidosis. Nevertheless, their beneficial roles in Nature have recently been identified, and artificial self-assembling of amyloid structure for various applications are emerging. LÄS MER
