  1. 1. Coping with Stress Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Kristina Heinrich; Kristina Jonas; Emanuele Biondi; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

  3. 3. Development of Salt-Sensitive Hypertension in Hydronephrosis

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mattias Carlström; Erik Persson; Nils Wåhlin; Russell Brown; Göran Bergström; [2008]
    Keywords : Physiology; blood pressure; nephrectomy; nitric oxide; oxidative stress; renal function; renin angiotensin system; salt-sensitivity; telemetry; tubuloglomerular feedback; ureteral obstruction; Fysiologi;

    Abstract : Hydronephrosis, due to ureteropelvic junction obstruction, is a common condition in infants with an incidence of approximately 0.5-1%. During the last decade, the surgical management of non-symptomatic hydronephrosis has become more conservative, and the long-term physiological consequences of this new policy are unclear. READ MORE

  4. 4. Angiotensin II and vascular disease. Studies in rats and atherosclerosis-prone mice

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maria E Johansson; Göteborgs universitet.; Gothenburg University.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiotensin II; atherosclerosis; AT1 receptor; AT2 receptor; blood pressure; hyperinsulinemia; hypertension; oxidative stress; salt; vascular disease; vascular function;

    Abstract : Angiotensin II (Ang II) is of importance for a number of physiological processes but also plays an important pathophysiological role in cardiovascular disease. The aim of this thesis was to evaluate the role of Ang II in hypertension-related atherosclerosis and vascular disease and to investigate possible anti-atherosclerotic effects of the angiotensin II, type 2 (AT2) receptor.

  5. 5. Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

    University dissertation from Viktoria Roos, Pure & Applied Biochemistry, Lund University

    Author : Viktoria Roos; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Metabolism; Biokemi; metabolism; osmotic stress; transcript profiling; DNA microarrays; random elongation mutagenesis; directed evolution; mRNA structure; Vitreoscilla haemoglobin VHb ; Escherichia coli; salt stress.;

    Abstract : Vitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. READ MORE
