  2. 6. The Physiological Cost of Antibiotic Resistance

    Author : Mirjana Macvanin; Diarmaid Hughes; Stanley Maloy; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; fusidic acid; fitness cost; protein synthesis; EF-G; ppGpp; RpoS; oxidative stress; heme; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

    Abstract : Becoming antibiotic resistant is often associated with fitness costs for the resistant bacteria. This is seen as a loss of competitiveness against the antibiotic-sensitive wild-type in an antibiotic-free environment. READ MORE

  4. 7. The chloroplast talks : Insights into the language of the chloroplast in Arabidopsis

    Author : Peter Kindgren; Åsa Strand; Barry Pogson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; photosynthesis; retrograde communication; Mg-ProtoIX; oxidative stress; gene expression; Molecular biology; Molekylärbiologi; Physiological Botany; fysiologisk botanik;

    Abstract : The chloroplast originates from an endosymbiotic event 1.5 billion years ago, when a free living photosynthetic bacteria was engulfed by a eukaryotic host. The chloroplastic genome has through evolution lost many genes to the nuclear genome of the host. READ MORE

  5. 8. Probiotics and berry-associated polyphenols: catabolism and antioxidative effects

    Author : Maja Jakesevic; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bilberry; Rosehips; Chokeberry; Probiotics; Lactic acid bacteria; Polyphenols; Ischemia-reperfusion; Oxidative stress;

    Abstract : Oxidative stress can cause damage to DNA, proteins and lipids and is associated with inflammation and various human diseases as cancer, atherosclerosis, and autoimmune diseases. Polyphenol-rich diet, such as fruits and berries, may act as antioxidants and prevent oxidative stress and, thereby, associated diseases. READ MORE

  6. 9. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Author : Jenny Lindberg; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE

  7. 10. Targeting NOX2 in cancer

    Author : Ebru Aydin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; reactive oxygen species; immunotherapy; nox2; nk cells; melanoma; histamine; metastasis; leukemia; aml; cml; kras; mpd;

    Abstract : Reactive oxygen species (ROS) are short-lived, toxic derivatives of oxygen that are produced during mitochondrial respiration and by NADPH oxidases (NOX). By enzymatically generating ROS, the myeloid cell NOX2 plays a critical role in defense against bacteria and other microorganisms. READ MORE
