  2. 1. Modelling Evolution : From non-life, to life, to a variety of life

    Author : Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. READ MORE

  4. 2. Influenza A Virus : Spatial analysis of influenza genome trafficking and the evolution of the neuraminidase protein

    Author : Dan Dou; Robert Daniels; Martin Schwemmle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza A virus; IAV; neuraminidase; NA; IAV genome trafficking; viral entry; viral replication; co-infection; antigenic drift; antigenic shift; NA assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Abstract : Influenza A viruses (IAVs) are a common infectious agent that seasonally circulates within the human population that causes mild to severe acute respiratory infections. The severity of the infection is often related to how the virus has evolved with respect to the pre-existing immunity in the population. READ MORE

  5. 3. Viruses on the wing : evolution and dynamics of influenza A virus in the Mallard reservoir

    Author : Michelle Wille; Jonas Waldenström; Timm Harder; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Co-infections; Ecology; Epidemiology; Evolution; Host-Parasite Interactions; Immunity; Influenza A Virus; Mallard; Phylogeny; Virology; Waterfowl; Wild Birds; Wildlife Disease; Zoonotisk ekologi; Zoonotic Ecology;

    Abstract : This thesis explores the evolution of avian influenza A viruses (IAV), as well as host-pathogen interactions between these viruses and their main reservoir host, the Mallard (Anas platyrhynchos). IAV is a genetically diverse, multi-host virus and wild birds, particularly dabbling ducks, are the natural reservoir. READ MORE

  6. 4. Influenza neuraminidase assembly : Evolution of domain cooperativity

    Author : Diogo da Silveira Vieira da Silva; Robert Daniels; Ron Fouchier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Influenza; neuraminidase; assembly; transmembrane domain; evolution; Biochemistry; biokemi;

    Abstract : Influenza A virus (IAV) is one of the most common viruses circulating in the human population and is responsible for seasonal epidemics that affect millions of individuals worldwide. The need to develop new drugs and vaccines against IAVs led scientists to study the main IAV surface antigens hemagglutinin (HA) and neuraminidase (NA). READ MORE

  7. 5. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE
