1. 21. Magnetic relaxation studies of self-associating and membrane proteins

   Författare :Michael Gottschalk; Lund University Bioimaging Center; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-lactoglobulin A; Biokemisk teknik; Biochemical technology; HEWL; BPTI; bacteriorhodopsin; protein self-association; membrane proteins; NMR; magnetic relaxation dispersion;

   Sammanfattning : Magnetic relaxation dispersion measurements have been performed on aqueous protein solutions to study the dynamics of waters in the proton transport channel of bacteriorhodopsin and the self-association of the proteins BPTI, lysozyme and beta-lactoglobulin. The measurements have focused on the bulk relaxation rates, R1 and R2, of three water nuclei 1H, 2H and 17O that are coupled to the protein environments by exchange and therefore report on properties such as the protein tumbling and dynamics of internal waters.

3. 22. Metabolic impact of certain dietary proteins and/or amino acids - Glycaemic and hormonal responses to carbohydrate meals in healthy subject

   Författare :Ulrika Gunnerud; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amino acids; dietary protein; glycaemic regulation; insulin; incretins;

   Sammanfattning : Re-occurring hyperglycaemic episodes promote subclinical low-grade inflammation and CVD in type 2 diabetes, emphasising the therapeutic role of tight blood glucose regulation. A tight blood glucose regulation is probably beneficial also in healthy subjects and mild elevations in postprandial glycaemia and triglycerides are associated with impaired flow-mediated dilation and increased markers of oxidative stress in young healthy subjects.

4. 23. Crossflow Microfiltration of particle Suspensions - The influence of hydrodynamics and physico-chemical interactions

   Författare :Ingmar Harald Huisman; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ceramic membranes; shear-induced diffusion; crossflow microfiltration; silica particles; zeta potential; Livsmedelsteknik;

   Sammanfattning : Crossflow microfiltration is a technique to separate suspended particles (or cells or droplets) from liquids by use of a membrane that is permeable for the liquid but impermeable for the particles. The permeate flow drives particles to the membrane surface, where they may be deposited and form a fouling layer. LÄS MER

5. 24. Insulinogenic Effects of Milk- and Other Dietary Proteins, Mechanisms and metabolic implications

   Författare :Mikael Nilsson; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; Nutrition; Type 2 diabetes; Isolated islets; Incretin hormones; Food proteins; Amino acids; Insulin index; Glycaemic index; Hyperinsulinaemia; Insulin; Blood glucose; Milk; Whey;

   Sammanfattning : The metabolic syndrome (type 2 diabetes, obesity, hypertension, atherosclerotic cardiovascular disease, dyslipidaemia, and hyperinsulinaemia), is increasing in prevalence world-wide. The progression of this syndrome proceeds through a step-wise deterioration of metabolic events where deterioration of insulin sensitivity appears to have a key role in a ?vicious circle? of hyperinsulinaemia/hyperglycaemia and insulin resistance.

7. 25. Structure and Phase Behavior of Protein Solutions

   Författare :Björn Persson; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical Mechanics; Simulations; Protein Interactions; Phase Separation; Aggregation; Mutual Amplification;

   Sammanfattning : The complexity of proteins is reflected in the structure of their fluids. This is seen from strongly inhomogeneous distributions about the single protein. Using molecular simulations of protein models, based on experimental structures, the present work probes the directional forces between proteins. LÄS MER
