    Sammanfattning : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.

  3. 2. Design, synthesis and evaluation of bacterial sialic acid uptake inhibitors

    Författare :Tiago Bozzola; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sialic Acid; antibacterial agents; Medicinal Chemistry; Synthesis; uptake inhibitors;

    Sammanfattning : Antibiotic resistance is a major threat for our society and finding novel antibacterial therapies is of greatimportance. In this thesis, we investigate bacterial sialic acid uptake inhibitors as a novel antibacterial approach.Bacteria do not biosynthesise sialic acid and therefore harvest it from the host. LÄS MER

  4. 3. Physiological demands of competitive elite cross-country skiing

    Författare :Magnus Carlsson; Michail Tonkonogi; Christer Malm; Eva Andersson; Högskolan Dalarna; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Performance capability; maximal oxygen uptake; lactate threshold; lean mass; double poling; power output; maximal speed; sprint skiing; distance skiing.; Hälsa och välfärd; Health and Welfare;

    Sammanfattning : Introduction Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables to the competitive performance of elite skiers. LÄS MER

  5. 4. In Vivo Active Drug Uptake and Efflux at the Blood-Brain Barrier : With Focus on Drug Transport Interactions

    Författare :Muhammad Waqas Sadiq; Margareta Hammarlund-Udenaes; Sven Björkman; N. Joan Abbott; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; Active uptake transport; Microdialysis; P-glycoprotein; Drug interactions; Species differences; Pharmacokinetics; Pharmacodynamics; NONMEM; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight junctions between endothelial cells and energy dependent transporters in the BBB influence rate and extent of drug distribution to the brain. LÄS MER

  7. 5. Dekkera bruxellensis – a Competitive Yeast for Ethanol Production from Conventional and Non-conventional Substrates

    Författare :Johanna Blomqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the ethanol industry and research community, Saccharomyces cerevisiae is regarded as the most competitive fermentation yeast and therefore industrial yeast populations are rarely studied. This thesis investigates yeast and lactic acid bacteria (LAB) populations in a Swedish ethanol plant. LÄS MER
