  2. 6. Strategies for Monitoring of Endocrine Disrupting Chemicals in Aquatic Environment

    Author : Pär Hallgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vitellogenin; Endocrine disruption; alkali-labile phosphate; Carassius carassius; steroid hormones; Oncorhynchus mykiss; membrane exraction; supercritical fluid extraction; GC;

    Abstract : The protein biomarker vitellogenin in fish is discussed alongside alterative strategies for monitoring of endocrine disrupting chemicals. The first objective was to find a cheap, robust and generic method for the quantification of vitellogenin. READ MORE

  4. 7. Membrane rafts and its GPI anchored complement inhibitors regulate insulin secretion

    Author : Vini Nagaraj; Diabetes - öpatofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Membrane rafts; basal insulin secretion; regulated insulin secretion; CD59; CD55; SNARE proteins; insulin; pancreatic beta cells.;

    Abstract : Type 2 diabetic patients usually exhibit an abnormal lipid profile. One such lipid that is constantly elevated in T2D is cholesterol. At the cellular level, cholesterol aids in tight packing of sphingolipids in certain regions of the plasma membrane and these specialized regions are termed ‘membrane rafts’, which act as signalling hubs.

  5. 8. Heat-Induced Cell Membrane Injury of Vegetable Tissues -An applied study on potatoes

    Author : Gerardo Gonzalez-M; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; PME; active transport; Cell membrane injury; potatoes;

    Abstract : Heat processing of vegetables involves the use of temperatures above the physiological limit which affect the cellular structures of the tissue and induce a series of events at cell level that will in turn be reflected in the transport properties of the tissue. One of the most important cellular structures from the mass transport point of view is the cell membrane since it represents the physical barrier to the transport of nutrients into and out of the cell.

  6. 9. Dynamic protein trafficking of the nuclear membrane and in peroxisomes

    Author : Charlotta Buch; Einar Hallberg; Howard J. Worman; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The cell nucleus is enclosed by the nuclear envelope (NE), a double lipid membrane separating the nucleoplasm from the cytoplasm. Transport of macromolecules between the nucleus and the cytoplasm takes places through nuclear pore complexes (NPCs) in a selective and energy dependent manner. READ MORE

  7. 10. Lipid Turnover in Plants and Yeast, A Study of Storage Lipid Synthesis and Lipid-Based Signalling in Plants and Yeast

    Author : Maria Gustavsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; turnover; plasma membrane; plant; PLA2; biosynthesis; S. cerevisiae; triacylglycerol;

    Abstract : In this thesis, lipid biosynthesis is discussed focussing on the genes and enzymes involved in the final step of storage lipid synthesis, on the enzyme phospholipase A2, and on cell membrane lipid homeostasis. The investigation of lipid metabolism revealed that in Saccharomyces cerevisiae, there are four genes that are essential for the final step of storage lipid biosynthesis; ARE1, ARE2, DGA1, and LRO1.
