1. 21. Island biogeography and population divergence in the Skyros wall lizard

   Författare :Anna Runemark; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Podarcis gaigeae; inbreeding; predation release; polymorphism; island gigantism; the island rule; genetic drift; sexual selection; natural selection; island biology; Evolution;

   Sammanfattning : Islands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies.

3. 22. IRON NUTRITION DURING EARLY CHILDHOOD. Factors influencing iron status and iron intake

   Författare :Ann-Cathrine Bramhagen; Preventiv pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; feeding situation; Medicine human and vertebrates ; Pediatrics; Medicin människa och djur ; iron deficiency; Pediatri; maternal experinces; influencing factors; iron intake; child*;

   Sammanfattning : The overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. LÄS MER

4. 23. Dynamics of omnivorous crayfish in freshwater ecosystems

   Författare :Karin Olsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; crayfish; freshwater ecosystems; niche width; growth rate; stable isotope analysis; recruitment; RNA:DNA analysis; Ecology; food availability and quality; trophic position; population dynamics;

   Sammanfattning : In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis.

5. 24. Epidermal Reactions to Injury with Implications for Innate Immunity

   Författare :Markus Roupé; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; epidermis; Wound healing; interleukin-8; Antimicrobial peptides;

   Sammanfattning : Abstract The epidermis is one of our primary interfaces towards the external milieu. Following injury, the physical barrier function of the skin is destroyed and the epidermis is left vulnerable to microbial invasion. LÄS MER

7. 25. Degranulation in macrophages and other leukocytes: regulation by calcium, phosphoinositide 3-kinase, and protein kinase C

   Författare :Claes Nauclér; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lysosomal secretion; neutrophil; Clinical biology; proton pump; Klinisk biologi; exocytosis; lysosomal pH;

   Sammanfattning : Macrophages mediate innate immunity through release of cytokines, eicosanoids, reactive oxygen species as well as through phagocytosis and secretion of lysosomal enzymes. Regulation of lysosomal secretion in macrophages differs in several respects from release of specialized granules in other leukocytes. LÄS MER
