1. 1. Cellular targets of HAMLET, their role in tumor cell death and therapeutic potential

   Författare :Aftab Nadeem; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer therapy; colon cancer; bladder cancer; cell death; HAMLET; alpha-lactalbumin; oleate; membrane lipids; nucleotide-binding protein; Ras GTPases; alpha-helical peptides;

   Sammanfattning : Protein-lipid complexes have broad and specific effects against cancers of different origins. HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a complex of partially unfolded α-lactalbumin and oleic acid that kills a wide range of tumor cells but leaves healthy differentiated cells unaffected.

3. 2. Disturbed Islet Function and Alterations in Islet Protein Expression

   Författare :Henrik Ortsäter; Peter Bergsten; Franz Schuit; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; islet; glucose; oleate; corticosterone; oxygen tension; insulin release; protein profiling; Clark-like electrodes; SELDI-TOF MS; PPI-B; 11β-HSD1; Cellbiologi; Cell biology; Cellbiologi;

   Sammanfattning : Pancreatic β-cells sense the concentration of glucose in the systemic circulation through metabolism of the sugar molecule. Failure to correlate the blood sugar concentration to an appropriate metabolic signal disrupts the function of the β-cell as a controller of glucose homeostasis and may contribute to the development of type 2 diabetes mellitus.

4. 3. Surfactants based on natural products - enzymatic synthesis and functional characterization

   Författare :Fredrik Viklund; KTH; []
   Nyckelord :Enzymatic synthesis; Surfactants; Antioxidants; Ascorbyl oleate; Polyethylene glycol PEG esters; Hemolysis; Transepithelial electrical resistance; Ionic liquids; Candida antarctica lipase B;

   Sammanfattning : Surfactants are molecules that contain a water-soluble and afat-soluble part. They have important functions in productssuch as detergents, cosmetics, pharmaceuticals and foods aswell as in many industrial processes. Surfactants are used onvery large scale, which makes it important to decrease theirimpact on the environment. LÄS MER

5. 4. Shape Control Synthesis and Microstructure Studies of Metal Nanoparticles

   Författare :Xin Wen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hexadecyltrimethylammonium bromide; sodium oleate; polyvinylpyrrolidone; Gold nanorod; palladium nanodendrite; seed mediated growth; transmission electron microscopy; hexadecyltrimethylammonium chloride;

   Sammanfattning : Metal nanoparticles have been extensively studied in recent years due to their unique chemical, biological and physical properties. Gold (Au) and palladium (Pd) nanoparticles are two of the most popular materials because Au nanoparticles have a strong localized surface plasmon resonance effect and Pd nanoparticles have high hydrogen adsorption and chemical catalytic capacities.

7. 5. Lipid Self-Assembly and Lipase Action

   Författare :Johanna Borné; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

   Sammanfattning : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .
