1. 1. Plant lipid transfer proteins : Evolution, expression and function

   Författare :Monika Edstam; Johan Edqvist; Kristina Blomqvist; Jenny Hagenblad; Frederica Theodoulou; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The plant non-specific lipid transfer proteins (nsLTPs) are known for the ability to transfer different lipids in vitro, but their in vivo functions have not yet been elucidated. They seem to play a role in the defense against biotic and abiotic stresses; the gene expression of nsLTPs is often upregulated when exposed to stresses. LÄS MER

3. 2. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

   Författare :Quoc Dat Pham; Fysikalisk kemi; []
   Nyckelord :stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

   Sammanfattning : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

4. 3. On the interaction between wort protein and iso-humulone : A study of surface rheology, interfacial structures and particle formation with the relevance to beer foam

   Författare :Yi Lu; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wort barley protein; lipid transfer protein; protein Z; iso-humulone; Ellipsometry; Surface rheology;

   Sammanfattning : Beer is one of the most popular drinks in the world. Foam is a unique characteristic of beer, contributing to mouthfeelings and visual perceptions. Therefore, it would be worthwhile to study the solution and interfacial properties ofbeer and assess them with regards to foam. LÄS MER

5. 4. DNA-Controlled Lipid-Membrane Fusion

   Författare :Lisa Simonsson; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

   Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

   Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER
