1. 16. Non-image-forming effects of light : Implications for the design of living and working environments

   Författare :Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

   Sammanfattning : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. LÄS MER

3. 17. Epidemiological, clinical anf pathogenetic studies of acute intermittent porphyria

   Författare :Ingemar Bylesjö; Christer Andersson; Pertti Mustajoki; Umeå universitet; []
   Nyckelord :Medicine; Acute intermittent porphyria; epilepsy; melatonin; diabetes mellitus; white-matter lesions; symptoms; Medicin; Medicine; medicin;

   Sammanfattning : Porphyrias are inherited metabolic disorders characterised by an impairment of heme biosynthesis. Acute intermittent porphyria (AIP) is the most common of the acute porphyrias in Sweden. Acute attacks of AIP are characterised by neuro-psychiatric symptoms, including epileptic seizures. LÄS MER

4. 18. Drug repositioning in chemoprevention of colorectal cancer

   Författare :Naiqi Zhang; Allmänmedicin och klinisk epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drug repositioning; Colorectal cancer CRC ; Pharmacoepidemiology; Chemoprevention; Melatonin; Proguanil; Atovaquone; Selective serotonin reuptake inhibitor SSRI ;

   Sammanfattning : BackgroundColorectal cancer (CRC) ranks as the third most frequently occurring cancer and the second leading cause of cancer-related deaths worldwide. In response to the high demand for an effective prevention strategy, chemoprevention, using medications to block the pathogenetic pathways of disease, might be an attractive strategy to offer a more effective option at a low cost.
