1. 11. The developing rat kidney : the dopamine system and related serine/threonine kinases and phosphatases

   Författare :Johan Svennilson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :apoptosis; confocal immunofluorescence; DARPP-32; dopamine; foetal renal development; hypertension; in situ hybridization; metanephric culture; mouse; nephron number; PKC; PP1 PP2A; protein phosphorylation; rat;

   Sammanfattning : The kidney originates from the fusion and conversion of two tissues: the metanephric mesenchyme and the ureter epithelium, an evagination from the Wolffian duct. Although a number of candidate molecules have been shown to be of importance for the differentiation of the embryonic kidney, many of the signalling pathway leading to this development are still obscure.

3. 12. Understanding the environmental regulation of tree phenology

   Författare :Tetiana Svystun; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phenological events; environmental cues; temperature response; phenological modelling; frost risk; gross primary production; climate change impact;

   Sammanfattning : In temperate and boreal climates, trees synchronise their annual growth cycles with seasonal changes in daylength and temperature. Understanding how environmental cues regulate tree phenology is important to our ability to capture the potential responses of trees to climate change, with implications for forest productivity.

4. 13. Embryonic Stem Cells: Differentiation into Insulin Producing Cells and Elimination of Damaged Proteins

   Författare :Gabriella Brolén; Stamcellscentrum (SCC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; oxidatively damaged proteins; diabetes; carbonyl; C-peptide; Medicine human and vertebrates ; insulin; human embryonic stem cell; 20S proteasome; AGE; Pdx1; proinsulin;

   Sammanfattning : This thesis includes two different parts: One focusing on how to induce human embryonic stem cells (hESCs) to differentiate into insulin producing cells by following the normal pancreatic development pathway. These cells have then the potential to be an unlimited source for diabetes regenerative medicine. LÄS MER

5. 14. Mechanisms of Lung Injury in a Mouse Model of Bronchopulmonary Dysplasia

   Författare :Anna Hogmalm; Göteborgs universitet; []
   Nyckelord :bronchopulmonary dysplasia; transgenic mice; inflammation; lung; interleukin-1; αvβ6 integrin; mmp-9; surfactant;

   Sammanfattning : Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects preterm infants. Increased levels of inflammatory mediators in the amniotic fluid and in the lungs of preterm infants are associated with the development of BPD. LÄS MER

7. 15. ABA and chromatin remodelling regulate the activity-dormancy cycle in hybrid aspen

   Författare :Anna Petterle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : One of the most important survival strategies plants have evolved is the cessation of growth and development of dormancy in response to the seasonal changes. Apical meristems of deciduous woody plants living in temperate and boreal zones undergo a yearly cycle between an active and a dormant state, which allows them to protect the meristem and avoid damage provoked by extremes of low temperatures during the winter.
