  1. 1. Deg/HtrA proteases of the cyanobacterium Synechocystis sp. PCC 6803 from biochemical characterization to their physiological functions

    Detta är en avhandling från Umeå : Umeå University

    Författare :Xuân Tâm Lâm; Umeå universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deg; HtrA; protease; chaperone; Synechocystis sp. PCC 6903; biochemical characterization; physiological function; proteomics; structure;

    Sammanfattning : The family of Deg/HtrA proteases is present in a wide range of organisms from bacteria, archaea to eukaryota. These ATP-independent serine endopeptidases play key roles in the cellular protein quality control. The cyanobacterium Synechocystis sp. LÄS MER

  2. 2. Ventricular rotation and the rotation axis a new concept in cardiac function

    Detta är en avhandling från Umeå : Umeå university

    Författare :Ulf Gustafsson; Umeå universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Cardiology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Kardiologi; Cardiology; kardiologi;

    Sammanfattning : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. LÄS MER

  3. 3. Ventricular Long Axis Function: Amplitudes and Timings Echocardiographic Studies in Health and Disease

    Detta är en avhandling från Umeå : Umeå university

    Författare :Frederick Bukachi; Umeå universitet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.

  4. 4. Spatio-temporal processing of surface electromyographic signals information on neuromuscular function and control

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Christer Grönlund; Umeå universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER

  5. 5. Growth hormone in the brain Focus on cognitive function

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erika Brolin; Uppsala universitet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; central nervous system; cognition; morphine; gamma-hydroxybutyrate; diabetes; Barnes maze; Morris water maze; mice; rats; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Cognitive impairments are an increasing health problem worldwide. In the developed countries, the average life expectancy has dramatically increased over the last decades, and with an elderly population more cases of cognitive impairments appear. LÄS MER
