  2. 21. Mechanism-Based Modeling of the Glucose-Insulin Regulation during Clinical Provocation Experiments

    Author : Petra Jauslin-Stetina; Mats Karlsson; Nicolas Frey; Philippe Jacqmin; Uppsala universitet; []
    Keywords : Pharmacokinetics Pharmacotherapy; Glucose homeostasis; Type 2 diabetes; IVGTT; OGTT; Meal test; Circadian variation; Mechanism-based; NONMEM; Farmakokinetik Farmakoterapi;

    Abstract : Type 2 diabetes is a complex chronic metabolic disorder characterized by hyperglycemia associated with a relative deficiency of insulin secretion and a reduced response of target tissues to insulin. Considerable efforts have been put into the development of models describing the glucose-insulin system. READ MORE

  4. 22. Coordination of two different genomes in response to light and stress

    Author : Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Abstract : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. READ MORE

  5. 23. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster

    Author : Hao Cao; Helgi B. Schiöth; Michael J. Williams; Jan Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xenobiotics; metabolism; insulin signalling; circadian rhythm; carcinogen; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Abstract : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.

  6. 24. Melanization and Hemocyte Homeostasis  in the Freshwater Crayfish, Pacifastacus leniusculus

    Author : Chadanat Noonin; Irene Söderhäll; Kenneth Söderhäll; Smith Valerie; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; melanization; prophenoloxidase; caspase; hematopoiesis; thymosin; astakine; circadian rhythm; reactive oxygen species; tyrosinase; prokineticin;

    Abstract : Blood cells or hemocytes play important roles in immunity. They are a major source of many immune-related molecules such as antibodies in adaptive immunity of vertebrates and prophenoloxidase (proPO) in invertebrates. READ MORE

  7. 25. The rhythm of adolescence : morningness-eveningness and adjustment from a developmental perspective

    Author : Anna-Karin Andersson [Andershed]; Margaret Kerr; Mats Gillberg; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; morningness-Eveningness; circadian rhytmicity; sleep-wake; adolescence; development; social adjustment; school adjustment; family relations; risk; delinquency; impulsiveness; sensation-seeking; Psychology; Psykologi; Psykologi; Psychology;

    Abstract : In recent developmental research, sleep-wake patterns and preferences, in other words Morningness-Eveningness, have been shown to be related to various kinds of problem behavior. Previous research on adolescents has demonstrated that individuals with a sleep-wake preference toward staying up late in the evening and arising late in the morning (i.e. READ MORE
