  1. 1. Image Filtering Methods for Biomedical Applications

    Author : M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. READ MORE

  2. 2. Modulation of retinal progenitors : A bird’s-eye view of retinal regeneration and disease

    Author : Dardan Konjusha; Finn Hallböök; Rusty Lansford; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Developmental neurobiology; Retinoblastoma; MYCN; Cone photoreceptor; Nolz1; Endothelin; Müller cells;

    Abstract : The cell populations of the retina and their intricate organization provide us with one of the most important senses – vision. All retinal cell populations are derived from a common progenitor pool as a result of tight regulation of proliferation, differentiation, dedifferentiation, and programmed cell death. READ MORE

  3. 3. 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.

  4. 4. Voicing on the borders of language

    Author : Imogen Stidworthy; Konsthögskolan i Malmö; []
    Keywords : HUMANIORA; HUMANITIES; Language; Voicing; Listening; Non-verbal communication; Metacinematic; Rub-up; Installation; Video art; Cinema; Image; Non-retinal image; Sound; Mirroring; Mimesis; Post-cinematic affect; Autism; Aphasia; Cross-modal sensing; Synaesthesia; Psychoanalysis; Neurology; Developmental psychology; Infant development; Intensive interaction; Speech therapy; Auditory surveillance; Forensic listening; Psychiatry;

    Abstract : My research engages with the varieties of relationship between verbal and non-verbal forms of language and communication. I approach the issue through three people who live or work with non-verbal people on the autistic spectrum: Phoebe Caldwell, Fernand Deligny and Iris Johansson. READ MORE

  5. 5. Retinal morphology and function in prematurely-born children at school age

    Author : Hanna Åkerblom; Gerd Holmström; Anne Fulton; Uppsala universitet; []
    Keywords : Retinopathy of prematurity; Prematurity; Retinal development; OCT; Fullfield ERG; Multifocal ERG; Ophtalmology; Oftalmiatrik;

    Abstract : Preterm birth may lead to complications during the neonatal period that can cause visual dysfunctions. Retinopathy of prematurity (ROP) and neurological complications are well known reasons for visual dysfunctions, but preterm children with no or only mild ROP and no evident neurological problems may also be affected visually when they grow up.
