    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heme-proteins; optical manipulation; resonance Raman spectroscopy; microfluidic systems; single cells; Medical Engineering for Healthcare;

    Sammanfattning : Recent advances in microbiology and biomedicine require development of tools to monitor the response of single cells to environmental stimuli under controlled physiological conditions. In this thesis, I describe how this can be achieved by combining various spectroscopic techniques with optical tweezers and microfluidic systems. LÄS MER

  4. 3. Direct imaging of Stimulated Raman scattering : 3D spatial control and spatial generation

    Författare :Ronja Eriksson; Kerstin Ramser; Mikael Sjödahl; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Stimulated Raman scattering (SRS) is a powerful imaging technique that has become popular during the last decades for its ability to image species specific in a sample with high accuracy. The purpose of this thesis is twofold. Firstly, to demonstrate 3D spatial control of where in the sample SRS is generated. LÄS MER

  5. 4. Optical Monitoring of Cerebral Microcirculation

    Författare :Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Sammanfattning : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

  7. 5. Development of Methods to Investigate Pulmonary Arterial Smooth Muscle Cells under Hypoxia

    Författare :Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Fredrik Nikolajeff; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Hypoxic pulmonary vasoconstriction (HPV) is a physiological response to localized alveolarhypoxia that is intrinsic to the pulmonary circulation. By hypoxia-induced contractionof pulmonary arterial smooth muscle cells (PASMCs), the pulmonary capillary bloodflow is redirected to alveolar areas of high oxygen partial pressure, thus maintaining theventilation-perfusion ratio.
