1. 1. Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands

   Författare :Anna Hansson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bis-crown ether analogue; molecular recognition; molecular tubes; Tröger s base; dihalo-analogues;

   Sammanfattning : Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. LÄS MER

3. 2. Applications of Four-Colour Fluorescent Primer Extension Technology for SNP Analysis and Discovery

   Författare :Annika Ahlford; Ann-Christine Syvänen; Mats Nilsson; David Schwartz; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single nucleotide polymorphism; Genotyping; Massively parallel sequencing; Gene mapping; Lab-on-a-chip; Medical genetics; Medicinsk genetik; Molecular biology; Molekylärbiologi; Molekylär medicin; Molecular Medicine;

   Sammanfattning : Studies on genetic variation can reveal effects on traits and disease, both in humans and in model organisms. Good technology for the analysis of DNA sequence variations is critical. Currently the development towards assays for large-scale and parallel DNA sequencing and genotyping is progressing rapidly.

4. 3. Molecular regulation of epithelial tube size

   Författare :Erika Tång Hallbäck; Göteborgs universitet; []
   Nyckelord :Drosophila; tube shape; trachea; chitin; luminal matrix; epithelial tubes; morphogenesis; chloride channel; subapical actin;

   Sammanfattning : In nature, epithelial tubes are vital structures in organ design and are required for transport of gases and liquids in organs, such as the vascular system, the vertebrate lung and the kidneys. The tubular epithelium is single layered, but is often reinforced by layers of muscular support. LÄS MER

5. 4. Characterization of regulatory factors controlling tip growth in Nicotiana tabacum pollen tubes

   Författare :Jia Sun; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Rho GTPases constitute a family of highly conserved signaling proteins with key functions in the regulation of cellular polarization and polar cell growth. In plants, Rho GTPases are represented by a plant specific subfamily referred to as Rac/Rop GTPases. LÄS MER

7. 5. In silico studies of carbon nano tubes and metal clusters
