    Abstract : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. READ MORE

  4. 2. Effects of domestication related genes on behaviour, physiology and gene expression in chickens

    Author : Anna-Carin Karlsson; Per Jensen; Randi Oppermann Moe; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Domestication, the process when animals adapt to captivity, tends to modify a whole array of traits towards what has been termed “the domesticated phenotype”, where the domesticated animal differs from its wild ancestor in morphology, physiology, development and behaviour. Physiological traits and behaviours are controlled by genes. READ MORE

    Abstract : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. READ MORE

  6. 4. Visual thinking, visual speech : a semiotic perspective on meaning-making in molecular life science : how visualizations, metaphors and help-words contribute to the formation of knowledge about proteins among upper secondary and tertiary level students

    Abstract : Molecular life science has become one of the fastest-growing fields of scientific and technical innovation. An important issue for tomorrow’s education is to meet the challenge posed by various facets of molecular life science. READ MORE

  7. 5. Models of Retinal Development and Disease

    Author : Minas Hellsand; Finn Hallböök; Emma Andersson; Department of Cell and Molecular Biology Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; retinal organoids; retinoblastoma; MYCN; Stargardt disease; Bardet-Biedl syndrome; model systems;

    Abstract : For a model of a human disease to be valid and useful, it is important that key genotypic and phenotypic traits are shared between model system and human. The work in this thesis has been focused on generating new and characterizing spontaneous models of three genetic disorders affecting the retina: retinoblastoma, a childhood cancer with its origin in the fetal retina, Stargardt disease, a juvenile form of macular degeneration, and Bardet-Biedl syndrome, a pleiotropic ciliopathy featuring retinal degeneration.
