    Sammanfattning : Nanopore based sensing technology has been widely studied for a broad range of applications including DNA sequencing, protein profiling, metabolite molecules, and ions detection. The nanopore technology offers an unprecedented technological solution to meeting the demands of precision medicine on rapid, in-field, and low-cost biomolecule analysis. LÄS MER

  2. 2. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Louise Adermark; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Sammanfattning : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.

  3. 3. Numerical Analysis of Partial Admission in Axial Turbines

    Detta är en avhandling från Stockholm : KTH

    Författare :Narmin Baagherzadeh Hushmandi; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Sammanfattning : HTML clipboard Numerical analysis of partial admission in axial turbines is performed in this work. Geometrical details of an existing two stage turbine facility with low reaction blades is used for this purpose. For validation of the numerical results, experimental measurements of one partial admission configuration at design point was used. LÄS MER

  4. 4. The Role of Angiotensin II in Experimental Acute Kidney Injury and Cardiorenal Failure

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sofia Jönsson; Uppsala universitet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; Acute kidney injury; Angiotensin II; Fluid balance; Cardiac function; Renal function;

    Sammanfattning : Blood pressure and fluid regulation are kept constant through the interaction between heart and kidneys. When the systemic blood pressure decreases, the levels of the hormone Angiotensin II increase, leading to vasoconstriction and therefore increased blood pressure. LÄS MER

  5. 5. Mechanism of pathological angiogenesis in adipose tissue and tumor

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Microbiology, Tumor and Cell Biology

    Författare :Yuan Xue; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Angiogenesis is critical for both malignant diseases, such as cancer, and non-malignant diseases, such as obesity and metabolic disorders. Majority of tissues and organs are highly vascularized. The malfunctions of tissue microenvironment are always accompanied with or dependent on the alterations of vasculature. LÄS MER
