  1. 36. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology

    Författare :Felicia Seemann; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulär magnetresonanstomografi; Fysiologi; Atrioventrikulär klaffplansrörlighet; Mitralisflöde; Tryck-volym loopar; Kraft-längd loopar; Cardiovascular magnetic resonance; Physiology; Atrioventricular plane displacement; Transmitral flow; pressure-volume loops; Ventricular force-length loops;

    Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER

  3. 37. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Författare :Lin Wang; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.

  4. 38. Glutamate and GABA signalling components in the human brain and in immune cells

    Författare :Amol K. Bhandage; Bryndis Birnir; Gerard P. Ahern; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neuroscience; Neurovetenskap; Immunologi; Immunology;

    Sammanfattning : Glutamate and γ-aminobutyric acid (GABA) are the principal excitatory and inhibitory neurotransmitters in the central nervous system (CNS). They both can activate their ionotropic and metabotropic receptors. LÄS MER

  5. 39. The γ-aminobutyric acid and proton signaling systems in the zebrafish brain : Characterization and effect of stress

    Författare :Arianna Cocco; Svante Winberg; William H. J. Norton; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; g-aminobutyric acid GABA ; GABAA receptors; adult zebrafish; central nervous system; gene expression profiling; extracellular acidification.; Biokemi; Biochemistry;

    Sammanfattning : The central nervous system of vertebrates is continuously processing sensory information relayed from the periphery, integrating it and producing outputs transmitted to efferents. In the brain, neurons employ an array of messenger molecules to filter afferent information and finely regulate synaptic transmission. LÄS MER

  7. 40. Influence of genetics and mechanical properties on large arteries in man

    Författare :Rachel De Basso; Toste Länne; Martin Björck; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Arterial pathology is the major contributor to cardiovascular diseases and mortality. The mechanical properties of arteries are independent factors for cardiovascular disease and mortality, where genetics influence the structure of the arterial wall, which may result in change in arterial stiffness.
