2. 1. DNA-Controlled Lipid-Membrane Fusion

   Author : Lisa Simonsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; exocytosis; vesicles; DNA; FRET; fluorescence resonance energy transfer; model system; total internal reflection fluorescence microscopy; TIRF microscopy; self-assembly; site-specificity; diffusion; biomembranes; lipid bilayer; membrane fusion;

   Abstract : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. We have demonstrated that short DNA oligonucleotides, membrane-attached via CH in an orientation that mimics the overall zipperlike architecture of fusion-inducing proteins, induce fusion of both suspended vesicles and vesicles site-specifically tethered to SLBs.

4. 2. Aspects of trade credit

   Author : Stefan Ingves; Handelshögskolan i Stockholm; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This dissertation presents various aspects of how and why firms use trade credit. This is done by using several different models that make it possible to concentrate on one, or a few, aspects at a time. The analysis is carried out with the help of tools and methods provided by ordinary microeconomic theory. READ MORE

5. 3. Themis v. Xiezhi: Assessing Judicial Independence in the People's Republic of China under International Human Rights Law

   Author : Jonas Grimheden; Raoul Wallenberg institutet för mänskliga rättigheter och humanitär rätt; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; China; judicial jndependence; international law; comparative law; independence of the judiciary; mänskliga rättigheter; human rights; Chinese law; law; judicial Reform; komparativ rätt;

   Abstract : The first of three parts in this study elaborates on international human rights law and drawing on the most essential international instruments and jurisprudence, the criteria constituting judicial independence are distilled as a framework for assessment. The point of departure is that judicial independence is a necessary guarantee for the enjoyment of human rights rather than a privilege of judges. READ MORE

6. 4. NMR structral studies on ruthenium complexes binding to DNA

   Author : Lisha Wu; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; DNA binding; Ru-complex dimer; CD; fluorescence; molecular dynamics simulation;

   Abstract : The Ru-complex Λ,Λ-[bidppz(bipy)4Ru2]4+ (Λ,Λ-B) exhibits multiple modes of interactions with the palindromic DNA dodecamer [d(CGCGAATTCGCG)]2, however excluding any type of intercalation as shown by both optical spectroscopy and NMR. NMR observation of Λ,Λ-B titration into a DNA solution results in both a transient binding, with observation of fast exchange for protons located near the ends of the DNA duplex, and a more stable interaction in the DNA minor groove indicated by a slow exchange mechanism and binding sites for G2, G4 and A5 of the same DNA strand.

7. 5. Gastric gland luminal pressure and mucosal protection : An in vivo study in the anesthetized rat

   Author : Ingrid Synnerstad; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; acid secretion; bicarbonate; epithelial cell surface pH; gastric gland; muscularismucosa; micropuncture; mucosal blood flow; mucus gel thickness; omeprazole; permeability; prostaglandins; ranitidine; rat; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Abstract : The driving force for creation of channels in gastric mucus, for acid and pepsin transport, ismost probably the hydrostatic pressure generated within the gastric gland lumen. The aim ofthis study was to investigate the origin and regulation of the glandular pressure. READ MORE
