   Författare :Malin Masterton; G. Mats Hansson; T. Anna Höglund; Søren Holm; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; posthumous interests; moral standing; missing subject; archaeology; human remains; rights; dead; interests; Practical philosophy; Praktisk filosofi; Bioetik; Bioethics;

   Sammanfattning : Genetic research has increasing power to analyse old biological remains. Biological traces of well-known historical persons can reveal personal information. The aim of this thesis is to investigate ethical concerns for the dead, within the biological, historical and archaeological sciences. LÄS MER

3. 2. Considering a Baby? Responsible Screening for the Future : Ethical and social implications for implementation and use of preconception expanded carrier screening in Sweden

   Författare :Amal Matar; Anna T Höglund; Mats G. Hansson; Lars Sandman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preconception expanded carrier screening; reproductive autonomy; solidarity; popula-tion screening; genomics; ELSI;

   Sammanfattning : Preconception expanded carrier screening is a novel technology that involves the offer of a screening test for many recessive diseases (via an expanded screening panel) to prospective parents, with no priori risk. Test positive couples have a number of reproductive choices; prenatal diagnosis and aborting affected fetus, IVF and preimplantation genetic diagnosis, sperm or ovum donation or simply accept the risk.

4. 3. Species interactions and energy transfer in aquatic food webs

   Författare :Jens Munk Nielsen; Monika Winder; Sture Hansson; Michael T. Brett; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aquatic food webs; zooplankton; stable isotope analysis amino acids; molecular diet analysis; Marine Ecology; marin ekologi;

   Sammanfattning : Food webs are structured by intricate nodes of species interactions which govern the flow of organic matter in natural systems. Despite being long recognized as a key component in ecology, estimation of food web functioning is still challenging due to the difficulty in accurately measuring species interactions within a food web.

5. 4. Transcriptional regulation and effects on differentiation by LMO proteins and the basic helix-loop-helix factors TAL1 and HEN1

   Författare :Anders Hansson; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetik; cytogenetik; cytogenetics; Genetics; HEN1; differentiation; LMO; LIM proteins; TAL1; T-ALL; bHLH;

   Sammanfattning : Acute lymphoblastic leukemia (ALL) is the most widespread type of cancer, as well as the most frequent leukemia in children. Malignant ALL cells originate from normal T lymphocytes or B cells that are blocked at immature stages of differentiation. LÄS MER

7. 5. Phagocyte-induced apoptosis in natural killer cells and T cells. Role of reactive oxygen species and regulation by histamine

   Författare :Markus Hansson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Malignant tumors frequently contain an infiltrate of leukocytes, usually cells of the monocyte/macrophage lineage and lymphocytes with anti-tumor activity such as natural killer (NK) cells and T cells. Clinical and experimental data suggest that monocytes/macrophages in tumors inhibit functions of adjacent NK cells/T cells and thereby suppress lymphocyte-dependent anti-tumor immunity. LÄS MER
