  1. 11. 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).

  3. 12. The immunomodulatory properties of C-Med 100 an extract of the plant Uncaria tomentosa

    Författare :Christina Silver; Diabetes - immunovirologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; survival; proliferation; inhibition; NF-kB; Uncaria tomentosa; quinic acid;

    Sammanfattning : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. LÄS MER

  4. 13. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

    Författare :Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

    Sammanfattning : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. LÄS MER

  5. 14. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Författare :Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

    Sammanfattning : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. LÄS MER

  7. 15. PACAP and airway regulation with special reference to smooth muscle and neutrophils

    Författare :Johan Kinhult; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; Otorhinolaryngology; allergy; neutrophils; smooth muscle; PACAP; airway regulation;

    Sammanfattning : The investigations focus on the neuropeptidepituitary adenylate cyclase-activating peptide and its effects on airway regulation, with emphasis on smooth muscle relaxation and neutrophil activation and migration. In the nasal mucosa, PACAP-containing nerve fibers were localized invascular smooth muscle and close to seromucous glands. LÄS MER
