  1. 31. Arcanobacterium haemolyticum, clinical, diagnostic and therapeutic aspects

    Författare :Mats Nyman; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; Microbiology; phenotypic characteristics.; penicillin tolerance; antibiotic susceptibility; antibody reaction; exanthema; Arcanobacterium haemolyticum; pharyngitis; bakteriologi; virologi; mykologi;

    Sammanfattning : In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. LÄS MER

  3. 32. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

    Författare :Louise Olsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

    Sammanfattning : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis thaliana; AAA-ATPases; abscisic acid; chloroplast; drought; embryo-lethal; FtsH metalloprotease; intrinsic water-use efficiency WUEi ; leaf variegation; outdoor conditions; oxidative stress; plastid biogenesis; proteomics; protein import; root-associated bacterial communities seedlings; Biochemistry; biokemi; molekylärbiologi; Molecular Biology; biology; biologi;

    Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER

  5. 34. Optimizing nicotinic acid delivery for durable antilipolysis and improved metabolic control

    Författare :Tobias Kroon; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Type 2 diabetes is a devastating disease affecting hundreds of millions worldwide. Lipid accumulation in peripheral non-adipose tissues is a major driver of insulin resistance, a central pathophysiological defect of this disease. LÄS MER

  7. 35. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Författare :Gösta Lilius; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.
