  2. 1. Cyanide and central nervous system : a study with focus on brain dopamine

    Author : Gudrun Cassel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Abstract : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. READ MORE

  4. 2. Neonatal complications following birth by vacuum extraction

    Author : Katarina Åberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Vacuum extraction is a common method of delivery presently accounting for approximately 7 percent of all deliveries in Sweden. It is considered an important and safe obstetric procedure, although both maternal and neonatal complications exist. READ MORE

  5. 3. Trace Element Analysis with Application to Environmental Pollutants Studies in Vietnam

    Author : Thi Hong Nguyen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blood; environmental samples; discriminant analysis; ICP-MS; coal mining; hair; EDXRF; microwave digestion; CV-AAS; urine; sample preparation; coal combustion;

    Abstract : In the work presented here the attention has been focused on optimising sample preparation and analytical techniques for trace element determination, analytical quality assurance and environmental applications. Trace element concentrations in various environmental matrices were investigated using Energy Dispersive X-ray Fluorescence (EDXRF), Inductively Coupled Plasma Mass Spectro-metry (ICP-MS) and Cold Vapour Atomic Absorption Spectrometry (CV-AAS).

  6. 4. Mechanisms of excitability in the central and peripheral nervous systems : Implications for epilepsy and chronic pain

    Author : Jenny Tigerholm; Erik Fransén; Dieter Jaeger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendritic excitability; synchronized synaptic input; multicompartment model; epilepsy; axonal excitability; silent C–fibres; Hodgkin–Huxley dynamics; conduction velocity; KA;

    Abstract : The work in this thesis concerns mechanisms of excitability of neurons. Specifically, it deals with how neurons respond to input, and how their response is controlled by ion channels and other active components of the neuron. READ MORE

  7. 5. Malaria in travellers and migrants

    Author : Andreas Wångdahl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Malaria is a potentially fatal disease that caused approximately 241 million cases and 627 000 deaths in 2020, most in children in Sub-Saharan Africa. In non-endemic countries, malaria is imported by travellers and migrants and timely management and treatment is crucial. READ MORE
