1. 21. Calcium Responses in the Renal Afferent Arteriole to Angiotensin II and Norepinephrine Stimulation

   Författare :Mark Kornfeld; Klinisk neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norepinephrine; angiotensin II; smooth muscle cells; afferent arteriole; calcium; Kidney; renal hemodynamics; Physiology; Fysiologi;

   Sammanfattning : Studies were performed to investigate the influence of the vasoconstrictors angiotensin II (AII) and norepinephrine (NE) on calcium metabolism in smooth muscle cells of afferent arterioles. Fura-2 and image analysis techniques were used to evaluate calcium responses in the proximal and distal parts of afferent arterioles with attached glomeruli. LÄS MER

3. 22. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

   Författare :Ingrid Bölin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

   Sammanfattning : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. LÄS MER

4. 23. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles

   Författare :Antonio M. Gutiérrez; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mesangial cells; nucleotide receptors; purinoceptors; desensitization; afferent arterioles; ATP; UTP; adenosine; protein phosphatases; calcium; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Sammanfattning : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. LÄS MER

5. 24. The involvement of calcium and membrane fusion events in neutrophil secretion and respiratory burst

   Författare :Daniel Granfeldt; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; calcium; regulated secretion; membrane fusion; SOC; arachidonic acid; intracellular fusion; oxygen free radicals; phagocytosis;

   Sammanfattning : Neutrophil granulocytes play an important role in host defence during the early stages of microbial infection. The neutrophils have to leave the blood stream and migrate out into the tissue where they are able to phagocytose and kill microbes as well as dispose of cell debris from damaged tissues. LÄS MER

7. 25. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

   Författare :Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; Materials Chemistry; materialkemi;

   Sammanfattning : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. LÄS MER
