2. 1. Interrogation of drug effects on the lipid composition of single cells and Drosophila brain using ToF-SIMS imaging

   Author : Thuy Mai Hoang Philipsen; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; Keywords: Mass spectrometry imaging; PC12 cell.; ToF-SIMS; zinc deficiency; lipid change; methylphenidate; cocaine; cognition; omega-3 and 6- fatty acids;

   Abstract : Lipids are essential for all living organisms on Earth. The most important function of lipids is that they act as the building blocks of cellular membranes. Lipids consist of polar head groups and non-polar tail groups and assemble into bilayer structures to create cell and organelle membranes. READ MORE

4. 2. Interorganellar connectivity : From protein to lipid homeostasis

   Author : Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

   Abstract : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

5. 3. Amylopectin - Interactions with Lipids and Proteins

   Author : Henrik Lundqvist; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binding isotherm; isothermal titration calorimetry; differential scanning calorimetry; retrogradation; alpha-lactalbumin; beta-lactoglobulin; whey protein; surfactant; lipid; exterior chain length; barley; potato; starch; amylopectin; amylose; Food and drink technology; Livsmedelsteknik; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

   Abstract : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.

6. 4. Lipid biomarkers and other geochemical indicators in paleoenvironmental studies of two Arctic systems : a Russian permafrost peatland and marine sediments from the Lomonosov Ridge

   Author : Rina Argelia Andersson; Magnus Mörth; Richard Pancost; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipid biomarkers; peat; permafrost; Arctic Ocean; marine sediments; geokemi; Geochemistry;

   Abstract : The reconstruction of past environmental conditions is a fascinating research area that attracts the interest of many individuals in various geological disciplines. Paleoenvironmental reconstruction studies can shed light on the understanding of past climates and are a key to the prediction of future climate changes and their consequences. READ MORE

7. 5. Localisation of Fluorescent Probes and the estimation of Lipid Nanodomain sizes by modern fluorescence techniques

   Author : Radek Sachl; Lennart B-Å Johansson; Martin Hof; Mats Almgren; Tomas Obsil; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; fluorescence; rafts; lipid bilayer; bicelles; micelles; fysikalisk kemi; Physical Chemistry;

   Abstract : The thesis is divided into two major parts. The first part focuses on the localisation of probes in lipid/polymeric bilayers and in GM1 micelles. Included in this thesis is a new approach based on electronic energy transfer/migration (FRET/DDEM), which efficiently determines transversal positions of fluorescent molecules in lipid bilayers.
