1. 6. Short- and long-term effects of long-chain free fatty acids on pancreatic α- and β-cell function

   Författare :Charlotta Olofsson; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetologi; sekretion; Endokrinologi; diabetology; secreting systems; Endocrinology; type-2 diabetes.; intracellular free Ca2 ; exocytosis; Free fatty acids; pancreatic α- and β-cells;

   Sammanfattning : We have investigated the in vitro effects of long-chain free fatty acids (FFAs) on mouse pancreatic α- and β-cells by a combination of electrophysiological recordings, intracellular Ca2+ ([Ca2+]i) microfluorimetry and hormone release measurements. Acute addition of the saturated FFA palmitate to intact islets doubled insulin as well as glucagon secretion in the presence of 1 or 15 mM glucose and the FFA remained capable of enhancing release of both hormones in islets depolarised with high K+ in the presence of the KATP channel opener diazoxide, indicating that alterations of ATP sensitive potassium (KATP) channel activity is not part of the effect.

3. 7. Characterization of Impurities in Different Ferroalloys and Their Effects on the Inclusion Characteristics of Steels

   Författare :Yong Wang; Pär Jönsson; Andrey Karasev; Bart Blanpain; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferroalloys; electrolytic extraction; metal surface; non-metallic inclusions; steel cleanliness; computational thermodynamics; ferrolegering; elektrolytisk extraktion; metallyta; icke-metalliska inneslutningar; stålrenhet; beräkningstermodynamik; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning :      Ferroalloys have become increasingly important due to their indispensable role in steelmaking. As the performance requirements of steel materials increase, it is necessary to have a better understanding of the impact of impurities in ferroalloys on the steel cleanliness. LÄS MER

4. 8. “Jag älskar att allt ligger överst” : En designstudie av ytinteraktion för kollaborativa multimedia-framträdanden

   Författare :Rikard Lindell; Jan Gustafsson; Staffan Björk; Mälardalens högskola; []

   Sammanfattning : Den här doktorsavhandlingen presenterar ytinteraktion som ett gränssnitts-paradigm för grafiska användargränssnitt inom kreativa tillämpningar. Ytinteraktion utgår ifrån användarnas innehåll och allt innehåll presenteras på en oändligt stor tvådimensionell yta. LÄS MER

5. 9. Modelling effects of climate change and forestry on weathering rates and base cation cycling in forest soils

   Författare :Veronika Kronnäs; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; weathering; forest; biogeochemistry; Dynamic Modelling; ForSAFE;

   Sammanfattning : Base cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. LÄS MER

7. 10. Mechanisms for Targeting of Proteins to Secretory Lysosomes of Haematopoietic Cells

   Författare :Hanna Rosén; Avdelningen för hematologi och transfusionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; haematopoietic cells; Medicin människa och djur ; Medicine human and vertebrates ; secretory lysosomes; protein targeting;

   Sammanfattning : The cells of the innate immune system are essential for the host's first line defence against infection. Among these cells the neutrophil granulocyte has a central role by the production of antibiotic proteins and peptides. LÄS MER
