  1. 21. Analysis of risk factors in patients with severe chronic kidney disease. The role of atorvastatin

    Författare :Benny Holmberg; Bernd G Stegmayr; Christer Andersson; Peter M Nilsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atorvastatin; cholesterol; chronic kidney disease; haemodialysis; cholesterol; lipids; peritoneal dialysis; risk factors; statins; inter dialysis weight gain;

    Sammanfattning : Background and aim: There had been no randomized end-point studies with statins for patients with severe renal failure. The purpose of this prospective, open, randomized, controlled study was to investigate whether atorvastatin (10 mg/day) would alter cardiovascular end-points and the overall mortality rate of patients with chronic kidney disease stage 4 or 5 (creatinine clearanceMaterial & Methods: This was an open, prospective, randomized study.

  3. 22. Living on the edge : effectiveness of buffer strips in protecting biodiversity on boreal riparian forests

    Författare :Kristoffer Hylander; Christer Nilsson; Bengt Gunnar Jonsson; Ellen Macdonald; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; boreal forest; bryophyte; buffer strip; ecological boundary; edge effect; headwater stream; land snail; liverwort; moss; phytometer; riparian forest; substrate; terrestrial gastropod; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : The objective of this thesis is to evaluate the ecological consequences of buffer strip retention on riparian and terrestrial biodiversity. Earlier studies on forest buffer strips have evaluated their effectiveness in relation to water quality and aquatic biota. However, forests along streams are species rich habitats for many organism groups. LÄS MER
