1. 16. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

   Författare :Katarina Ekelund; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

   Sammanfattning : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. LÄS MER

3. 17. Molecular mechanisms in obesity-associated metabolic disease

   Författare :Louise Olofsson; Göteborgs universitet; []
   Nyckelord :obesity; metabolic syndrome; cholesterol; resting metabolic rate; insulin resistance; serum amyloid A; S100 calcium binding protein A1; Zn-alpha2-glycoprotein; CCAAT enhancer binding protein alpha;

   Sammanfattning : Obesity is associated with increased morbidity and mortality. Subjects with obesity are at risk of developing several serious conditions such as type 2 diabetes, hypertension, coronary heart disease and stroke. LÄS MER

4. 18. Phosphoinositides control insulin secretion through multiple routes

   Författare :Phuoc My Nguyen; Christina Bark; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phosphoinositides; PI 4 P; PI 4; 5 P2; Ca2 ; optogenetics; VDCC; Sac2; OSBP; OSW-1; cholesterol; membrane contact sites;

   Sammanfattning : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. LÄS MER

5. 19. Molecular Dynamic Simulations of Biological Membranes

   Författare :Qaiser Waheed; Olof Edholm; Friederike Schmid; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phospholipids; area compressibility; undulations; quantum corrections; cholesterol; phase transition; segregation;

   Sammanfattning : Biological membranes mainly constituent lipid molecules along with some proteins and steroles. The properties of the pure lipid bilayers as well as in the presence of other constituents (in case of two or three component systems) are very important to be studied carefully to model these systems and compare them with the realistic systems.

7. 20. The Impact of Birth Weight on Cardiovascular Risk Factors, Coronary Heart Disease and Prostate Cancer : Population-based Studies of Men Born in 1913 and Followed up Until Old Age

   Författare :Margaretha Eriksson; Kurt Svärdsudd; Lena Hulthén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; birth weight; coronary heart disease; cardiovascular disease; diabetes; blood pressure; hypertension; cholesterol; prostate cancer; cohort studies; follow-up studies; Family medicine; Allmänmedicin;

   Sammanfattning : Objectives. To study whether birth weight (BW) was correlated to cardiovascular risk factors, coronary heart disease (CHD), cardiovascular disease (CVD), and prostate cancer (PCA) at adult ages, whether a possible relationship depended on mediating factors from birth time, hereditary circumstances, and adult life variables, and what importance possible associations might have for the rate of the complaint in the general population.
