2. 1. Chewing gum and human hair as retrospective dosimeters

   Author : Axel Israelsson; Håkan B.L. Pettersson; Eva Lund; Håkan Gustafsson; Mats Eriksson; Bastian Breustedt; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Retrospective dosimeters are sometimes needed after radiological/nuclear (RN) exposures to determine the doses to individuals. Conventional dosimeters may not be at hand or may not be applicable calling for alternative materials. READ MORE

4. 2. Characterization of human myeloid progenitors and their differentiation

   Abstract : All hematopoietic cells are derived from the hematopoietic stem cells (HSCs) in a continuous and dynamic process, regulated by a network of transcription factors in different combinations and extrinsic signals from growth factors (GFs) and other factors in the microenvironment. In the initial stages of hematopoiesis HSCs differentiate to progenitor cells with gradually more restricted lineage potential and according to the most accepted model the first restriction in developmental potential results in commitment to either the lymphoid or the myeloid branch, in the latter followed by commitment to the neutrophil/monocyte and erythrocyte/megakaryocyte lineages.

5. 3. Mitochondrial function in sepsis - Temporal evolvement of respiratory capacity in human blood cells

   Author : Fredrik Sjövall; Lund Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; sepsis; severe sepsis; septic shock; platelets; mitochondria; OXPHOS; high-resolution respirometry; mitochondrial disorders; multiple organ failure; biogenesis; leukocytes; cytokines; respirometry; oxygen consumption; blood cells; temporal;

   Abstract : Sepsis is a devastating disease that is caused by the host’s response to an overwhelming infectious process. As sepsis progresses, organs distant from the site of infection become affected and sepsis-induced multiple organ failure ensues. READ MORE

6. 4. Hypoxia and differentiation in human neuroblastoma cells

   Author : Helén Nilsson; Institutionen för translationell medicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ontogeny; embryology human ; Utvecklingsbiologi; teratologi; embryologi människa ; teratology; cytogenetik; Development biology; cytogenetics; Genetik; Genetics; Medicin människa och djur ; HIF; Medicine human and vertebrates ; MYCN; Hypoxia; differentiation; Neuroblastoma;

   Abstract : The childhood tumour neuroblastoma is derived from immature cells of the sympathetic nervous system, which have become arrested at different maturation stages. Neuroblastoma is a malignancy with a high degree of heterogeneity, and there is a correlation between a poor differentiation status and a more aggressive phenotype. READ MORE

7. 5. The Plasminogen Activation System in Human Endometrium and Endometrial Cancer; Function, Tissue Localization and Prognostic Importance

   Author : Johanna Nordengren; Lund Obstetrik och gynekologi; []

   Abstract : The release of urokinase plasminogen activator (uPA) from endometrial stromal cells decreased after progesterone stimulation, due to upregulation of PA inhibitor 1 (PAI-1) and uPA receptor (uPAR). Subsequently, the uPA:PAI-1 complex was internalized and degraded via uPAR. READ MORE
