  2. 21. Molecular mechanisms involved in prokaryotic cycling of labile dissolved organic matter in the sea

    Author : Benjamin Pontiller; Jarone Pinhassi; Daniel Lundin; Catherine Legrand; Martin F. Polz; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bacteria and archaea; labile dissolved organic matter; metatranscriptomics; monomers; polymers; carbohydrate-active enzymes CAZymes ; peptidases; membrane transporters; Natural Science; Naturvetenskap; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Abstract : Roughly half of the global primary production originates from microscopic phytoplankton in marine ecosystems, converting carbon dioxide into organic matter. This organic matter pool consists of a myriad of compounds that fuel heterotrophic bacterioplankton. READ MORE

  4. 22. Glucose and glycerol transport in adipocytes from a structural perspective

    Author : Peng Huang; Medicinsk strukturbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipocytes; glucose and glycerol metabolism; glucose transporters; aquaglyceroporins; glucose transporter 4; aquaglyceroporin 7; protein and protein interaction; structure; single particle cryo-EM;

    Abstract : Adipocytes are crucial energy reservoirs to maintain metabolic homeostasis of glucose and lipids in the human body.Glucose transporters (GLUTs) and aquaporins (AQPs) play an important role in metabolic regulation of glucose andlipids in human adipocytes. READ MORE

  5. 23. Microglial Glutamate Transporters - Regulation of Expression and Possible Physiological Functions

    Author : Mikael Persson; Göteborgs universitet; []
    Keywords : anaphylatoxin; central nervous system; herpes simplex virus; glutamate transport; glutathione; GLT-1; lipopolysaccharide; microglia; neuroinflammation; oxidative stress; protection; tumour necrosis factor-alpha;

    Abstract : Microglia are considered as the immunocompetent cells of the central nervous system (CNS). Being the first line of defence, they have prominent roles in monitoring the homeostasis and the extracellular milieu and can rapidly and specifically react to any disturbances such as brain trauma, ischemia, neurodegenerative diseases, or infections.

  6. 24. Expression and regulation of water channels and ion transporters : ontogenic aspects

    Author : Masato Yasui; Karolinska Institutet; Karolinska Institutet; []
    Keywords : water balance; developmental gene expression regulation; gene transcription; fetal lung fluid; urinary concentrating capacity; hormonal regulation;

    Abstract : The content and distribution of body water changes dramatically during the perinatal period and in infancy. Transport of water across the cell membrane occurs via diffusion and via specific water channels. Transport via water channels is fast and may be hormonally regulated. READ MORE

  7. 25. The role of ABC transporters and inflammation in drug-resistant epilepsy

    Author : Lora Deuitch Weidner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis explores two pathologies thought to be related to drug resistance in epilepsy that may themselves be causally related: 1) overexpression of drug transporters in capillaries and 2) inflammation. With regard to the first hypothesis, overexpression of the ATP-binding cassette (ABC) transporters, P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), at the blood-brain barrier are thought to contribute to drug resistance in epilepsy.
