1. 11. Regulation of cellular plasticity and extracellular vesicle secretion in breast cancer

   Författare :Chrysoula Tsirigoti; Aristidis Moustakas; Carl-Henrik Heldin; Pierre Savagner; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cellular plasticity; extracellular vesicles; breast cancer; EMT; Molekylär medicin; Molecular Medicine; Molekylär cellbiologi; Molecular Cellbiology;

   Sammanfattning : Epithelial-to-mesenchymal transition (EMT) is a dynamic process controlling the transition of cells between epithelial and mesenchymal states in various physiological or pathological conditions. In cancer, EMT promotes cell dissemination and metastatic colonization, enriches tumors with stem cell populations and confers resistance to anticancer therapy. LÄS MER

3. 12. Midgut and muscle development in Drosophila melanogaster

   Författare :Margret Shirinian; Ruth Palmer; Anne Uve; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; visceral mesoderm; endoderm; somatic muscles; Alk; C3G; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : The fully developed and functional Drosophila midgut comprises two layers, the visceral mesoderm and the endoderm. The visceral muscle of the midgut is formed by the fusion of founder cells with fusion competent cells to form the muscle syncytia. LÄS MER

4. 13. Structured molecular sieves : synthesis, modification and characterization

   Författare :Valeri Naydenov; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : The work presented concerns synthesis of structured molecular sieves. The preparation procedure is based on the use of ion exchange resins as macrotemplates. Macroporous cation or anion exchange resin types were used depending on the molecular sieve type to be synthesized. LÄS MER

5. 14. A Solution Exchange Platform for Exposure of Cells to Chemical Waves

   Författare :Jessica Olofsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; waveform synthesis; solution exchange; cell signalling; patch clamp; receptor; high through-put; microfluidics; microfabrication; channel; chemical oscillations; ion channel; poly dimethylsiloxane ; drug discovery;

   Sammanfattning : This thesis presents the development, characterization and suggested applications of a platform for controlling the chemical environment around a cell or a cell constituent. The platform is unique in its capability to combine rapid solution switching with precise timing and access to a manifold of solution environments. LÄS MER

7. 15. Strategies for facilitated protein recovery after recombinant production in Escherichia coli

   Författare :My Hedhammar; Sophia Hober; Alois Jungbauer; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ion-exchange chromatography; protein A; Z; Zbasic; Zacid; fusion protein; proteolytic cleavage; immobilised protease; flow cytometry; inclusion bodies; solid-phase refolding; Molecular biology; Molekylärbiologi;

   Sammanfattning : The successful genomic era has resulted in a great demand for efficient production and purification of proteins. The main objective of the work described in this thesis was to develop methods to facilitate recovery of target proteins after recombinant production in Escherichia coli. LÄS MER
