1. 16. Virus inactivation - evaluation of treatment processes for food and biowaste

   Författare :Eva Emmoth; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Animal by-products and manure contain valuable plant nutrients that could be recycled onto arable land, as fertiliser. If these materials contain pathogenic microorganisms, such as viruses, transmission to domestic animals, wildlife and the food chain could occur. LÄS MER

3. 17. The Role of IgM and Complement in Antibody Responses

   Författare :Christian Rutemark; Birgitta Heyman; Claus Nielsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Complement; antibody response; mutated IgM; natural IgM; complement receptors; SIGN-R1; SAP; CRP; B cells; Medical Science; Medicinsk vetenskap;

   Sammanfattning : An intact complement system including the complement receptors 1 and 2 (CR1/2) is crucial for the generation of a normal antibody response in animals and humans. Moreover, activation of the classical pathway is thought to be important since deficiency in complement components C1q, C2, C4 or C3 lead to impaired antibody responses. LÄS MER

4. 18. Single Cell Investigations of the Functional Heterogeneity Within Immune Cell Populations : a Microchip-based Study

   Författare :Karolin Guldevall; Björn Önfelt; Hjalmar Brismar; Carsten Watzl; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biologisk fysik; Biological Physics;

   Sammanfattning : Immune cell populations are constantly divided into smaller and smaller subsets defined by newly emerging cellular markers. However, there is a growing awareness of the functional heterogeneities in between cells even within small populations, in addition to the heterogeneity over time. LÄS MER

5. 19. Effects of bacterial genotoxins on immune modulation, chronic inflammation and cancer development

   Författare :Anna Bergonzini; Teresa Frisan; Maria Fällman; Steffen Backert; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunologi; Immunology;

   Sammanfattning : The intestinal microbiome of Inflammatory Bowel Disease and colorectal cancer patients is enriched in genotoxin-producing bacteria, which cause DNA damage in the host cells.Genotoxins have recently been identified as a novel family of effectors produced by pathogenic and commensal bacteria.

7. 20. Interactions between platelets and complement with implications for the regulation at surfaces

   Författare :Per H. Nilsson; Kristina Nilsson Ekdahl; John Lambris; Ian Nicholls; Berhane Ghebrehiwet; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement system activation; regulation ; platelets activation; regulation ; biomaterials; biocompatibility; chondroitin sulfate-A; apyrase; C1q; C3; factor H; C4BP; ADP; Biomedical Sciences; Biomedicinsk vetenskap;

   Sammanfattning : Disturbances of host integrity have the potential to evoke activation of innate immunologic and hemostatic protection mechanisms in blood. Irrespective of whether the activating stimulus is typically immunogenic or thrombotic, it will generally affect both the complement system and platelets to a certain degree. LÄS MER
