  1. 16. Circadian plasticity in the neuromuscular junction of Drosophila melanogaster

    Författare :Kerstin Mehnert; Rafael Cantera; Charlotte Helfrich-Förster; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Neurobiologi; funktionell morfologi; Functional Zoomorphology;

    Sammanfattning : A biological clock exists in many organisms and controls rhythmic behaviors such as the activity pattern of locomotion. At the cellular level, it has been shown that circadian rhythms in the morphology of neurons exist in the fruit fly Drosophila melanogaster. LÄS MER

  3. 17. Effects of aging and inflammatory molecules on the suprachiasmatic circadian clock

    Författare :Mikael Nygård; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Circadian; suprachiasmatic; synaptic; inflammation; cytokine; SOCS; interferon; tumor necrosis factor; neuron; firing;

    Sammanfattning : The suprachiasmatic nucleus (SCN) is considered the master circadian pacemaker in the mammalian brain and is vital for generating physiological and behavioral circadian rhythms. During aging and inflammatory conditions the circadian system is frequently affected, but relatively little is known about the mechanisms underlying such effects. LÄS MER

  4. 18. En vårdande ljusmiljö inom intensivvård : Patienters upplevelser och effekter av en cyklisk belysningsintervention

    Författare :Marie Engwall; Karin Samuelson; Högskolan i Borås; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; care environment; circadian rhythm; health; intensive and critical care; lighting; sleep; recovery; wellbeing; Människan i vården; Människan i vården;

    Sammanfattning : Det övergripande syftet med avhandlingen var att beskriva och undersöka patienters - vårdade inom intensivvård - upplevelser och effekter av en cyklisk belysningsintervention utifrån hälsa, välbefinnande och återhämtning.Metod: En intervention bestående av ett automatiskt styrt belysningssystem var installerat på ett intensivvårdsrum.

  5. 19. Robustness Analysis of Intracellular Oscillators with Application to the Circadian Clock

    Författare :Camilla Trané; Elling W. Jacobsen; Eric Bullinger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Biology; Automatic control; Reglerteknik;

    Sammanfattning : Periodic oscillations underlie many intracellular functions, such as circadian time keeping, cell cycle control and locomotor pattern generation in nerve cells. These intracellular oscillations are generated in intricate biochemical reaction networks involving genes, proteins and other biochemical components. LÄS MER

  7. 20. Gene-environment factors in depressive disorders with a focus on circadian genes

    Författare :Louise Sjöholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Depressive disorders have a multifactorial etiology, where both environmental and genetic risk factors contribute. Depression is characterized by a depressed mood and accompanied by e.g. loss of interest and pleasure, disturbed sleep and appetite and difficulties in concentrating. LÄS MER
