  1. 1. Physiological trade-offs in reproduction and condition dependence of a secondary sexual trait

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Måns S. Andersson; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Trade-offs; life history; immune ecology; cost of reproduction; costs of immune response; sexual selection; migration; moult; Newcastle disease; HbA1C; Ficedula albicollis; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Animal Ecology; zooekologi;

    Abstract : This thesis examines parental condition, how it is traded off against reproduction and how it is displayed in a secondary sexual trait. The studies were performed on nest-box breeding collared flycatchers Ficedula albicollis on the island of Gotland, in the Baltic Sea. READ MORE

  2. 2. Costs and benefits of immune system activation on physiology, behavior and offspring phenotype from an immunoecological perspective

    University dissertation from Department of Biology, Lund University

    Author : Sandra Sköld Chiriac; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; immunoecology; acute-phase response; sickness behaviors; energy expenditure; fever; hypothermia; life history; maternal effects; terminal investment; costs of immune responses; Taeniopygia guttata; Parus major; Cyanistes caeruleus;

    Abstract : Pathogen challenges and host immune defenses can have substantial impact on life history patterns of animals. Biotic and abiotic factors may affect immunity in wild animals, influencing e.g., population dynamics and sexual selection. READ MORE

  3. 3. Mechanisms and Biological Costs of Bacterial Resistance to Antimicrobial Peptides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hava Lofton Tomenius; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; antibiotic resistance; fitness cost; Salmonella Typhimurium; Staphylococcus aureus; bile; serum; pH response; growth rate; mice; phoP; pmrB; waaY; LPS; LL-37; defensins; membrane potential; Mikrobiologi; Microbiology;

    Abstract : The global increasing problem of antibiotic resistance necessarily drives the pursuit and discovery of new antimicrobial agents. Antimicrobial peptides (AMPs) initially seemed like promising new drug candidates. Already members of the innate immune system, it was assumed that they would be bioactive and non-toxic. READ MORE

  4. 4. Costs in the ecology and evolution of the vertebrate immune system

    University dissertation from Lars Råberg, Ecology Building, S-223 62 Lund

    Author : Lars Råberg; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cost of resistance; ecological immunology; immunocompetence; Parus caeruleus; transgenic mice; Animal ecology; Djurekologi; blue tit; basal metabolic rate;

    Abstract : A central assumption of theories of the ecology and evolution of immunological defence is that defence has not only benefits (in the form of resistance against parasites), but also costs. The aim of my studies was to investigate the nature and magnitude of costs of the vertebrate immune system, and to examine some of the consequences of these costs. READ MORE

  5. 5. Development of vaccines and mouse models for chronic hepatitis C virus infection

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Sepideh Levander; Karolinska Institutet.; Karolinska Institutet.; [2016]

    Abstract : Chronic hepatitis C virus (HCV) infection is a major causative agent for severe liver disease and cancer worldwide. Globally, it is estimated that approximately 185 million people are infected with HCV and 130-170 million of these are chronic carriers of the virus (1, 2). READ MORE
