  1. 11. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Författare :Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. LÄS MER

  3. 12. Crisis in Energy Metabolism - Mitochondrial Defects and a New Disease Entity

    Författare :Gittan Kollberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Energy metabolism; Mitochondrial Disorders; mtDNA; multiple mtDNA deletions; Alpers-Huttenlocher syndrome; POLG1; GYS1; glycogen synthase; point mutation; Polymerase gamma;

    Sammanfattning : Impairment of energy metabolism may be associated with severe implications for affected individuals since all fundamental cell functions are energy-dependent. Disorders of energy metabolism are often genetic and associated with defects in the oxidative phosphorylation in mitochondria. LÄS MER

  4. 13. Intracranial Compliance and Secondary Brain Damage. Experimental and Clinical Studies in Traumatic Head Injury

    Författare :Konstantin Salci; Per Enblad; Pelle Nilsson; Peter Hutchinsson; Uppsala universitet; []
    Nyckelord :Neurosciences; Traumatic brain injury; Intracranial compliance; Secondary insults; Microdialysis; Neurointensive care; Neurovetenskap;

    Sammanfattning : Traumatic brain injury (TBI) renders the brain more vulnerable to secondary insults. The increased vulnerability can probably be explained by a combination of disturbances in hemodynamics, metabolism and craniospinal dynamics. Reduced ability to compensate for added intracranial volume, i.e. LÄS MER

  5. 14. Quality systems to avoid secondary brain injury in neurointensive care

    Författare :Lena Nyholm; Per Enblad; Camilla Fröjd; Anders Lewén; Bo-Michael Bellander; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Subarachnoid hemorrhage; Intracranial pressure; Quality register; Checklist; Nursing interventions; Pressure autoregulation; Intracranial compliance; Hyperthermia; Cerebral energy metabolism; Microdialysis and Brain tissue oxygenation.; Neurokirurgi; Neurosurgery;

    Sammanfattning : Outcome after traumatic brain injury (TBI) depends on the extent of primary cell death and on the development of secondary brain injury. The general aim of this thesis was to find strategies and quality systems to minimize the extent of secondary insults in neurointensive care (NIC). LÄS MER

  7. 15. Studies on lipoprotein metabolism and atherogenesis

    Författare :Katharina Slätis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ApoA1; ApoB; ApoE; atherosclerosis; bile acids; cholic acid; cholesterol; cholesterol absorption; CYP7A1; CYP8B1; dexamethasone; GC-1; PAI-1; thyroid hormone receptor; very low density lipoprotein receptor;

    Sammanfattning : Atherosclerosis is the primary cause of cardiovascular events such as angina pectoris and myocardial infarction, which together with stroke are responsible for around 50% of all deaths in the United States and Europe. Usually atherosclerosis develops over several decades and leads to a progressive narrowing of arterial vessels. LÄS MER
