  1. 1. Stromal and tumor cell responses to hypoxia and treatment within the glioma microenvironment

    Författare :Vasiliki Pantazopoulou; Avdelningen för translationell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; glioblastoma; tumor microenvironment; reactive astrocytes; hypoxia; CD44; p75NTR;

    Sammanfattning : Glioblastoma is the most aggressive primary brain tumor in adults. Despite treatment, tumors invariably recur, and the recurring tumor is resistant to therapies. New approaches are needed for the successful treatment of glioblastoma patients.Tumors are not simply a compilation of molecularly and phenotypically identical neoplastic cells. LÄS MER

  2. 2. Circadian rhythms in the auditory system

    Författare :Vasiliki Basinou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Circadian clocks have been found in numerous cell types and tissues of the body, allowing organisms to coordinate their daily biological functions. They generate cycles of behavioral and physiological processes with a period length of ~24h, which are synchronized to the rotation of the Earth and the subsequent daily changes in illumination, temperature and humidity.

  3. 3. Implicit structured sequence learning

    Författare :Vasiliki Folia; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A simple question: Do you know how you manage to speak your native language without making grammatical errors despite the fact that you probably do not know how to describe the grammatical rules you use? Sometimes such simple questions do not have simple answers. The amazing capacity to effectively communicate complex information and thoughts through the medium of language is the result of the way language, and more specifically, linguistic rules are learned: in an implicit manner.

  4. 4. Sex, Molecules, and Gene control : Ecophysiological and evolutionary aspects of key sponge species from Antarctic shallow waters and the deep sea

    Författare :Vasiliki Koutsouveli; Paco Cárdenas; Anders Backlund; Ana Riesgo; Cassandra G. Extavour; Uppsala universitet; []
    Nyckelord :Porifera; Demospongiae; Geodia spp.; Phakellia ventilabrum; reproduction; gametogenesis; Antarctica; deep sea; sponge grounds; histology; molecular machinery; electron microscopy; RNA-seq; proteomics; lipidomics; Farmakognosi; Pharmacognosy;

    Sammanfattning : Very little is known about the ecophysiological aspects of Porifera (sponges) from Antarctica and North Atlantic, even though they are keystone components of these habitats. Being the earliest diverging metazoan lineage, sponges also play a fundamental role in our understanding of animal evolution. LÄS MER

  5. 5. Making Preciousness : Interaction Design Through Studio Crafts

    Författare :Vasiliki Tsaknaki; Ylva Fernaeus; Ron Wakkary; KTH; []
    Nyckelord :Interaction design; materials; making preciousness; studio crafts; resourceful composition; material sensuality; mattering artefacts; impermanence; incompleteness; imperfection; Human-computer Interaction; Människa-datorinteraktion;

    Sammanfattning : This dissertation explores value-creation in interaction design through practical collaborations with studio craftspersons. A focus is on the meaning of “preciousness” from a design perspective – what I refer to as Making Preciousness –  which highlights aspects of material properties, design processes, and the attitude to the design space.
