  2. 6. Role of Thrombospondin-1 in Endogenous and Transplanted Pancreatic Islets

    Author : Johan Olerud; Per-Ola Carlsson; Nils Welsh; Leif Jansson; Thierry Berney; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical cell biology; Medicinsk cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Type 1 diabetes mellitus is a severe life-long disease with a pronounced risk of developing secondary complications. One way to avoid the latter is to restore the fine tuning of blood glucose homeostasis by transplantation of pancreatic islets. READ MORE

  4. 7. The significance of ethylene and ethylene response factors in wood formation of hybrid aspen

    Abstract : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. READ MORE

  5. 8. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes

    Author : Marika Salonen Sloma; Diarmaid Hughes; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

    Abstract : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. READ MORE

  6. 9. Studies on the antiproliferative action of interferon : effects on proteins synthesized in the G1 and S phase of the cell cycle in 2 anchorage-dependent cell lines

    Author : Dan Lundblad; Erik Lundgren; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Interferon; Glioma; Antiproliferative effect; DNA polymerase; Thymidine kinase; 2 -5 oligo A; Protein synthesis; Two-dimensional electrophorensis; Mouse fibroblasts; C-myc; KI-67 antigen;

    Abstract : Interferons (IFNs) are a class of structurally related proteins first discovered to be produced by virus-infected cells. By now, several other inducing agents have been described. READ MORE

  7. 10. Synchronized delivery of inspired nitric oxide : Effects on oxygenation and pulmonary tension during artificial ventilation

    Author : Erkki Heinonen; Tim Higenbottam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; nitric oxide; pulsed administration; pulmonary hypertension; oxygenation; equine; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : Nitric oxide (NO) is a mediator of vascular smooth muscle tension that metabolises rapidly in blood. NO delivered by inhalation can therefore be used as a selective pulmonary vasodilator to relieve pulmonary hypertension or to improve oxygenation with no systemic effects. READ MORE
