  2. 16. Control of metabolism and hormone secretion from pancreatic alpha and beta cells

    Author : Jelena Stamenkovic; Diabetes - molekylär metabolism; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CLOCK genes; insulin; glucagon; metabolites; mitochondria; knock out;

    Abstract : Type 2 Diabetes (T2D) is a multifactorial disease, which has made it difficult to resolve its pathophysiology. We investigated processes that could contribute to the development of T2D. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 18. Deciphering the role of genetics and circadian rhythm in cluster headache

    Author : Carmen Fourier; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cluster headache (CH) is a complex neurovascular disorder with a distinct circadian attack pattern. Although many aspects of the disease’s pathophysiology remain to be elucidated, it is likely caused by a combination of different genetic and environmental risk factors. READ MORE

  6. 19. Gene-environment factors in depressive disorders with a focus on circadian genes

    Author : Louise Sjöholm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE

  7. 20. New insights into the regulation of stomatal movements by red light, carbon dioxide and circadian rhythms

    Author : Anastasia Matrosova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Stomata are small adjustable pores formed by pairs of guard cells that enable gas exchange between leaves and the atmosphere, thus directly affecting water loss and CO₂ uptake in plants. The current work focuses on the regulation of stomatal movements by red light, carbon dioxide and the circadian system and attempts to uncover molecular mechanisms that control guard cell function.
