    Sammanfattning : Surface durability is a key factor in the service life of components. Depending on the aggressiveness of the environment, surface deterioration by wear or corrosion leads to failure of the bulk material and eventually to the loss of functionality of the component. LÄS MER

  5. 4. Treatments and outcomes in bipolar disorder

    Författare :Erik Joas; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bipolar disorder; lithium; psychoeducation; CYP2C19; antidepressants; epidemiology; valproate; quetiapine; olanzapine; suicide;

    Sammanfattning : Bipolar disorder is defined by recurring mood episodes and patients have a markedly increased risk of suicide. Pharmacological and psychological treatments for bipolar disorder have proven efficacy in clinical trials yet the generalizability of current evidence to routine clinical practice is contested.
