2. 1. Enterovirus Infections of β-Cells : A Mechanism of Induction of Type 1 Diabetes?

   Author : Anna-Karin Berg; Gun Frisk; Torsten Tuvemo; Arne Andersson; Merja Roivainen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; enterovirus; type 1 diabetes; β-cells; human pancreatic islets; picornavirus; chemokines; nitric oxide; Pediatrik; Paediatric medicine; Pediatrisk medicin;

   Abstract : The process of β-cell destruction that leads to type 1 diabetes (T1D) is incompletely understood and it is believed to be a result of both genetic and environmental factors. Enterovirus (EV) infections of the β-cells have been proposed to be involved, however, the effects of EV infections on human β-cells have been little investigated. READ MORE

4. 2. Multicomponent diffusional reactions in tool steels : Experiment and Theory

   Author : Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; KTH; []
   Keywords : hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

   Abstract : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

5. 3. Cobalamin/folate status and its relation to cognition and behaviour in psychogeriatric patients

   Author : Karin Nilsson; Lund Psykiatri; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; klinisk psykologi; Psykiatri; psychosomatics; clinical psychology; Psychiatry; folate; Cobalamin; homocysteine; methylmalonic acid; dementia; psychogeriatric patients; delirium; psykosomatik;

   Abstract : The aim of this study was to evaluate the diagnostic potentials of four different biochemical markers, serum cobalamin, blood folate, plasma homocysteine and serum methylmalonic acid for diagnosis of cobalamin/folate deficiency in a psychogeriatric population. The second aim was to investigate the relationship between these markers and various clinical and functional parameters of the nervous system in patients with dementia disorders. READ MORE

6. 4. On enchytraeids and naidids: Life history traits and responses to environmental stress

   Author : Anna-Karin Augustsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; oligochaeta; terrestrial naididae; toxicity testing; asexual reproduction; sexual reproduction; drought; environmental stress; metal pollution; Ekologi; Animal ecology; Djurekologi;

   Abstract : My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. READ MORE
