  1. 21. Kynurenic acid in psychiatric disorders : studies on the mechanisms of action

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Klas Linderholm; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Kynurenic acid, a metabolite of tryptophan along the kynurenine pathway, is an endogenous antagonist at NMDA- and α7* nicotinic acetylcholine- (α7*nACh) receptors. Previous studies have shown that elevated levels of endogenous kynurenic acid are associated with an increased firing of midbrain dopamine neurons as well as a reduced prepulse inhibition (PPI), a behavioral model for sensorimotor gating.

  2. 22. A Knowledge-based System for Automatic Image Segmentation and Object Recognition

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Sören Molander; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The present thesis describes a system for automatic off-line scene analysis of individual images and image sequences. The analysis is based on the use of a priori procedural knowledge of the task and declarative knowledge of the scene to be analyzed. READ MORE

  3. 23. Immune recognition molecules in synaptic plasticity and regeneration of spinal motoneurons

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Sebastian Thams; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : This thesis is based on the emerging concept that pattern recognition molecules, originally characterized in the immune system, may be expressed and used by neurons to mediate non-immune functions. In line with this concept, the major histocompatibility complex (MHC) class I and certain complements proteins have been implicated in synaptic plasticity in the developing visual system. READ MORE

  4. 24. On causes and regulation of anti-viral defence in asthma and COPD

    University dissertation from Lund University: Faculty of Medicine

    Author : Mandy Menzel; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; chronic obstructive pulmonary disease; rhinovirus; exacerbation; airway epithelial cell; ; pattern recognition receptors; interferon; allergen; azithromycin; inflammasome; epithelial-derived cytokines; oxidative stress; asthma; chronic obstructive pulmonary disease; rhinovirus; exacerbation; airway epithelial cell; pattern recognition receptors; interferon; allergen; azithromycin; inflammasome; epithelial-derived cytokines; oxidative stress;

    Abstract : Rhinovirus infection is a main trigger of asthma and COPD exacerbations. dsRNA, a viral replication intermediate, is sensed by pattern recognition receptors in the airway epithelium leading to down-stream induction of anti-viral interferons. READ MORE

  5. 25. Studies on the mechanisms of action and physiological relevance of SOCS proteins

    University dissertation from Stockholm : Karolinska Institutet, Dept of Molecular Medicine and Surgery

    Author : Fahad Al-Zadjali; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Understanding systemic biological pathways and the key cellular mechanisms that dictate disease states, drug response, and altered cellular function in metabolic disorders is a significant challenge. Research in the last 20 years have made it clear that tissue communication, through the actions of endocrine, paracrine or autocrine factors play a significant role in pathogenesis of complex multiorgan diseases such as the metabolic syndrome.
