1. 21. Switching ON Fetal B Lymphopoiesis

   Författare :Trine Kristiansen; Avdelningen för molekylär hematologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; B-1 B cells; Lin28; Fetal hematopoietic stem cells;

   Sammanfattning : B-1a cells are innate-like lymphocytes that develop primarily during fetal and neonatal life, whereas adult bone marrow (BM) hematopoietic stem cells (HSCs) preferentially give rise to follicular B-2 cells. Functioning at the interface of the innate and adaptive immune systems, B-1a cells provide a non-redundant first line of defense prior to the temporally delayed establishment of a B-2 cell response.

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Keywords: Mass spectrometry imaging; PC12 cell.; ToF-SIMS; zinc deficiency; lipid change; methylphenidate; cocaine; cognition; omega-3 and 6- fatty acids;

   Sammanfattning : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. LÄS MER

4. 23. Contracting muscle for regeneration : myogenic dedifferentiation in limb progenitor cell formation

   Författare :Sara Lööf; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The urodele amphibians, such as newts and axolotls, are unique among vertebrates since they regenerate their limbs, tail, jaws and part of their heart and CNS as adults. After amputation of a newt limb, regeneration proceeds by the reversal of differentiation of tissues in the limb stump. LÄS MER

5. 24. Development of Transmission Electron Microscopy Techniques for the Study of Thin Films

   Författare :John P. McCaffrey; Bender Hugo; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Transmission electron microscopy (TEM) is an invaluable tool for the study of the physics and materials properties of thin films. This thesis addresses innovations and novel applications of TEM to materials physics, and consists of three parts: the examination and development of innovative TEM sample preparation techniques, conventional selected area electron diffraction with new techniques for data extraction, and an extended TEM investigation of quantum dots.

   Sammanfattning : The pancreas is a specialised multipurpose organ, that can be separated into two major compartments: endocrine and exocrine. The exocrine part makes up the majority of the organ volume and functions to secrete digestive enzymes into the small intestine. LÄS MER
