1. 16. Fetal hematopoietic cells in early gestation : aspects in view of fetal transplantation

   Författare :Sverker Ek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Fetal stem cells; fetal liver; fetal hematopoiesis; immunological ontogeny; fetal transplantation; cytokines; CD34 enrichment;

   Sammanfattning : The fetus as a patient is a challenge. There are opportunities for early, sometimes life-saving procedures or there may be advantages in prenatal rather than postnatal intervention. This is the case in fetal hematopoietic cell (FHC) transplantation where conditions caused by a defect in blood cell formation may be life-threatening to the fetus. LÄS MER

3. 17. Development of Protocols for Metabolomics in Biomedical Research using Chemometrics

   Författare :Anders Danielsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry; gas chromatography; design of experiments; Metabolomics; chemometrics; diabetes; metabolism; multivariate analysis;

   Sammanfattning : Metabolomics is a rapidly growing research field. It aims for quantification of all the metabolites in a biological sample such as plasma, saliva, cerebrospinal fluid or cells. LÄS MER

4. 18. Structural studies of glycoprotein sorting and processing complexes in the early secretory pathway

   Författare :Dominik Possner; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The secretory pathway of a eukaryotic cell exerts a stringently regulated quality control system for the correct folding and transport of newly synthesised proteins and their subsequent transfer to their final destinations. While this pathway has been mostly studied in yeast, it has become increasingly clear that aberrations in its function are the main causes of a range of human disorders, and we are still in the process of gathering knowledge of the underlying molecular structures and mechanisms of the disease-causing agents in order to fully understand their impact.

5. 19. From green to yellow : a leaf story

   Författare :Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

   Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER

7. 20. Characterization of p58 and rab1p, two proteins operating at the interface of the endoplasmic reticulum and the Golgi complex

   Författare :Ulla Lahtinen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :protein transport; rab1p; p58; animal lectin; intermediate compartment; endoplasmic reticulum; Golgi complex;

   Sammanfattning : Endomembranes participating in the early stages in exocytosis consist of the endoplasmic reticulum (ER), the Golgi complex, and vesicular transport intermediates at their interface. These vesicular transport intermediates were first visualized by following the synchronized transport of a viral membrane protein from the ER to the Golgi complex, which occurs at slower rates at reduced temperatures causing an accumulation of transport vesicles.
