  1. 1. Variability and adaptation in the contractile system of smooth muscle

    University dissertation from Mia Löfgren, Dept of Physiological Sciences, BMC F11, Tornavägen 10, 221 84 Lund, Sweden

    Author : Mia Löfgren; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; essential light chain; desmin; shortening velocity; integrin; intermediate filament; hypertrophy; non-muscle myosin; smooth muscle; myosin; heavy chain; Physiology; Fysiologi;

    Abstract : This thesis examines the cellular and molecular mechanisms involved in the large diversity of the contractile properties in smooth muscle. Six studies, I-VI, are included. I: a slow smooth muscle (aorta) has a different nucleotide and phosphate dependence compared to a fast type (taenia coli). READ MORE

  2. 2. Monitoring climate and plant physiology using deuterium isotopomers of carbohydrates

    University dissertation from Umeå : Fysiologisk botanik

    Author : Angela Augusti; Jürgen Schleucher; Vaughan Hurry; Howard Griffiths; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate reconstruction; deuterium; elevated CO2; isotopomer; nuclear magnetic resonance; photorespiration; tree-ring cellulose.; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : Climate is changing and it is certain that this change is due to human activities. Atmospheric greenhouse gases have been rising in an unprecedented way during the last two centuries, although the land biosphere has dampened their increase by absorbing CO2 emitted by anthropogenic activities.

  3. 3. Novel methods for improved tree breeding

    University dissertation from ; Dept. of Forest Genetics and Plant Physiology, Swedish University of Agricultural Sciences

    Author : Jon Hallander; Sveriges lantbruksuniversitet.; [2009]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The development and implementation of statistical tools to improve inference in sustainable forest tree breeding are presented here. By combining classical quantitative genetic theory and novel statistical methods, a number of parameters are optimized. READ MORE

  4. 4. Exhaled nitric oxide in extreme environments

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Tryggve Hemmingsson; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exhaled nitric oxide; hand-held instrument; electrochemical detector; microgravity; International Space Station; high altitude; hypobaric hypoxia; normobaric hypoxia; backdiffusion;

    Abstract : Exhaled nitric oxide (NO) is a useful marker for lower airway inflammation. Since NO was found to be a component of an exhaled breath in the early 1990´s, the Fractional Exhaled Nitric Oxide (FENO 50) measurement is now well accepted among clinicians as a complementary test in the management of asthma.

  5. 5. Conservation of transcription factors in infected cells of nitrogen-fixing root nodules

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Behnoosh Rashidi; Katharina Pawlowski; Karsten Niehaus; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; root nodules; actinorhiza; legumes; infection thread; Frankia; subtilase; leghemoglobin; chitinase; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Infected cells of nitrogen-fixing root nodules are the only plant cells that can stably internally accommodate a eubacterial symbiont. In the context of studying the differentiation of infected cells, we set about to analyse the conservation of infected cell-specific transcription factors using altogether four different promoters from genes showing infected cell-specific expression, or nodule-specific expression.
