  2. 16. Role of Fatty Acid Composition in Non-Alcoholic Fatty Liver Disease: a Dietary Perspective : Results from Interventional and Observational Studies

    Author : Michael Fridén; Ulf Risérus; Fredrik Rosqvist; Helen Lindqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fatty acids; Diet; Biomarkers; NAFLD; Liver fat; Fibrosis; Cirrhosis; HCC; Nutrition; Nutrition;

    Abstract : The overall aim of this doctoral thesis was to investigate the role of circulating, liver and dietary fatty acids in non-alcoholic fatty liver disease (NAFLD). For circulating and liver fatty acids, special emphasis was given to fatty acids reflecting diet. READ MORE

  4. 17. Unsaturated Fatty Acids in Alkane Solution : Adsorption and Tribological Properties

    Author : Sarah M. Lundgren; Per M. Claesson; Hugh Spikes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : Fatty acids and blends of fatty acids are used as friction modifiers and anti-wear additives in diesel fuels. A large part of some fatty acid blends are unsaturated fatty acids. Even though fatty acids have been thoroughly investigated, the adsorption and tribological behaviour of unsaturated fatty acids are no fully understood. READ MORE

  5. 18. Free fatty acids and insulin hypersecretion studied in human islets

    Author : Jing Cen; Peter Bergsten; Miriam Cnop; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; free fatty acids; palmitate; human islets; EndoC-βH1 cells; metformin; sorcin; insulin secretion; mitochondrial respiration; ER stress; human transcriptome array; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Free fatty acid (FFA) levels are increased in many obese subjects. High FFA levels stimulate the pancreatic beta-cells but have negative long-term effects. In obese children with high FFA levels circulating insulin concentration is high early in life but decline with age precipitating the development of type 2 diabetes mellitus (T2DM). READ MORE

  6. 19. Unlocking Sustainability in Wastewater Denitrification through Waste-Derived Volatile Fatty Acids

    Author : Tugba Sapmaz; Mohammad J Taherzadeh; Eric D. Van Hullebusch; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volatile fatty acids; wastewater denitrification; ammonium removal; sustainable carbon source; Resource Recovery; Resursåtervinning;

    Abstract : Carbon sources play a critical role in biological nitrogen removal during wastewater treatment, where strict total nitrogen limits on effluent discharge apply. Organic carbon sources serve as electron donors in the denitrification for heterotrophic denitrifiers. READ MORE

  7. 20. The dynamic surface nature of calcite and its role in determining the adsorptive stability toward hydrophobizing carboxylic fatty acids

    Author : Natalia Wojas; Per M. Claesson; Agne Swerin; Jan van Stam; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; calcite; recrystallization; surface modification; fatty acids; wear resistance; water resistance; contact angle hysteresis; AFM; XPS; VSFS; Kalcit; rekristallisation; ytmodifiering; fettsyra; nötningsbeständighet; vattenbeständighet; kontaktvinkelhysteres; Physical Chemistry; Fysikalisk kemi; Natural Sciences; Naturvetenskap; Chemical Sciences; Kemi; Tribology Interacting Surfaces including Friction; Lubrication and Wear ; Tribologi ytteknik omfattande friktion; nötning och smörjning ; Kemi;

    Abstract : Calcium carbonate has attracted a lot of interest over the centuries. Nowadays, mainly as mineral pigment and filler, it has a wide use in technological applications ranging from paper, construction, polymers, and environmental solutions to consumer goods. READ MORE
