1. 1. Haematopoietic Serine Proteases : A Cleavage Specificity Analysis

   Författare :Michael Thorpe; Lars Hellman; Urban Gullberg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mast cell; cleavage specificity; phage display; chymase; serine protease; granzyme; fish protease;

   Sammanfattning : Mast cells are innate immune cells, historically involved in allergy responses involving IgE. Through this, they have earned a reputation as a fairly detrimental cell type. Their beneficial roles remain somewhat enigmatic although they clearly have the ability to modulate the immune system. LÄS MER

3. 2. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management

   Författare :Therese Irminger Street; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small biotopes; incidental habitat; vascular plants; woody vegetation; grassland species; resource provisioning; species richness; habitat specificity; non-crop habitat; landscape complexity; heterogeneity; local management; agri-environment scheme;

   Sammanfattning : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.

4. 3. Targeting cytotoxic species in amyloid diseases

   Författare :Malin Lindhagen Persson; Anders Olofsson; Lars Tjernberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer s disease; Amyloid-beta; transthyretin; FAP; amyloid; cytotoxic species; oligomers; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Amyloid diseases are a world-wide problem causing great human suffer and large economical costs. Although amyloid deposits, a common denominator in all amyloid disorders, are detrimental to the surrounding tissue, there is a poor correlation between total amyloid burden and clinical symptoms.

5. 4. Contributions to the understanding of diversity and evolution in the genus Coreomyces

   Författare :Henrik Sundberg; Stefan Ekman; Åsa Kruys; Donald H. Pfister; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

   Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER

7. 5. The Quest for Functional Quasi-Species in Glutathione Transferase Libraries

   Författare :Arna Rúnarsdóttir; Bengt Mannervik; Ralf Morgenstern; Uppsala universitet; []
   Nyckelord :glutathione transferase; directed evolution; multivariate analysis; quasi-species; isothiocyanates; Biokemi; Biochemistry;

   Sammanfattning : Glutathione transferases (GSTs) are good candidates for investigations of enzyme evolution, due to their broad substrate specificities and structural homology. The primary role of GSTs is to act as phase II detoxifying enzymes protecting the cell from toxic compounds of both endo- and exogenous origins. LÄS MER
