21. Growth in Aging Colonies : The Importance of Being Different
Sammanfattning : The accumulation of rifampicin resistant (RifR) mutants in aging bacterial colonies has previously been attributed to stress-induced mutagenesis. Mutations giving rise to RifR are located in the rpoB gene, coding for the β subunit of RNA polymerase, RpoB. LÄS MER
22. Dynamics of root microorganisms in closed hydroponic cropping systems
Sammanfattning : Greenhouse production of vegetables in closed hydroponic cropping systems is a resource-efficient technique for the production of high-quality produce with a high yield per unit area. While this type of cropping system allows savings in terms of water and nutrient use, the recirculation of water increases the risk of pathogen dispersal. LÄS MER
23. The Wilms' tumor gene 1 (WT1) and leukemia -new insights and further complexity
Sammanfattning : The Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. LÄS MER
24. Fetal hematopoietic cells in early gestation : aspects in view of fetal transplantation
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
25. Innate immunity in Staphylococcus aureus arthritis and sepsis
Sammanfattning : Bacterial arthritis is a severe, rapidly progressing erosive disease with high morbidity and mortality. Staphylococcus aureus is the most common causative bacterium. Granulocytes together with cells from the monocyte/macrophage lineage, are the earliest leukocytes entering the synovial tissue in response to invading staphylococci. LÄS MER
