  2. 1. Horizontal gene transfer in plants - The story of PgiC2

    Author : Pernilla Vallenback; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plant genetics; Festuca ovina; PgiC; Horizontal gene transfer;

    Abstract : Sheep's fescue, Festuca ovina, is a common grass found all over Eurasia. In populations in southern Sweden some individuals were found to have two copies of the gene for cytoplasmic phosphoglucose isomerase, PgiC. READ MORE

  4. 2. Computational discovery of antibiotic resistance genes and their horizontal transfer

    Author : David Lund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetic analysis; Antibiotic resistance; horizontal gene transfer; computational screening;

    Abstract : Antibiotic resistance is increasing among clinical infections and represents one of the most serious threats to public health. Pathogens often become resistant by acquiring mobile antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT). READ MORE

  5. 3. Horizontal gene transfer by uptake of apoptotic bodies

    Author : Anna Bergsmedh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Horizontal gene transfer; genomic instability; apoptosis; phagocytosis;

    Abstract : In adults as well as during embryogenesis, apoptosis plays a key role in the elimination of cells in multicellular organisms. Apoptosis is important for the maintenance of tissue homeostasis. It is also of importance in tumor development, where tumor cells die by apoptosis due to low levels of oxygen and nutrients.

  6. 4. Olfactory Transfer of Analgesic Drugs After Nasal Administration

    Author : Ulrika Espefält Westin; Erik Björk; Eva Brittebo; Margareta Hammarlund-Udenaes; Paolo Colombo; Uppsala universitet; []
    Keywords : Pharmaceutics; Nasal administration; Olfactory transfer; Olfactory pathways; Central nervous system; Blood-brain barrier; Nasal respiratory mucosa; Olfactory mucosa; Olfactory bulb; Horizontal Ussing chamber; Morphine; Dihydroergotamine; Rat; Mouse; Swine; Autoradiography; Viability; Powder formulations; Galenisk farmaci;

    Abstract : Nasal administration of analgesics for achieving rapid pain relief is currently a topic of great interest. The blood-brain barrier (BBB) restricts access to the central nervous system (CNS) for several central-acting drugs, such as morphine and dihydroergotamine, which results in a substantial effect delay.

  7. 5. Heat Transfer in Circulating Fluidized Bed Boilers

    Author : Claes Breitholtz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; similarity; char; heat transfer; tube wall; circulating fluidized bed; particle; radiation; scaling; particle convection; gas convection;

    Abstract : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. READ MORE
