2. 1. Substrate Noise Coupling in Mixed-Signal Integrated Circuits: Compact Modeling and Grounding Strategies

   Author : Simon Kristiansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise reduction; substrate noise coupling modeling; elliptic integrals.; grounding resistance; Mixed-signal integrated circuits; z-parameter; substrate resistance; surface potential;

   Abstract : Integration of digital and analog circuits on the same chip is the result of the microelectronic industry's strive for low-cost, small, hand-held products. However, these mixed-signal circuits can experience interference problems; digital circuits inject noise into the substrate which is transmitted throughout the chip and received by sensitive analog circuits.

4. 2. Fat cell insulin resistance : an experimental study focusing on molecular mechanisms in type 2 diabetes

   Author : Frida Renström; Jan Eriksson; Anna Krook; Umeå universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipocyte; insulin signaling; insulin; glucose; IRS-1; glucose uptake; insulin resistance; typ 2 diabetes; serum; Medicine; Medicin;

   Abstract : The aim of the present thesis was to further increase our understanding of mechanisms contributing to and maintaining cellular insulin resistance in type 2 diabetes (T2D). For this reason, the effects of high glucose and insulin levels on glucose transport capacity and insulin signaling, with emphasis on insulin receptor substrate 1 (IRS-1) were assessed in fat cells.

5. 3. Sulphonamide Resistance in Neisseria meningitidis and Commensal Neisseria Species

   Author : Yvonne Qvarnström; Göte Swedberg; Dan Andersson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; sulphonamide resistance; Neisseria; natural transformation; adaptive evolution; substrate channelling; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

   Abstract : Extensive use of the sulphonamide drugs against the bacterium Neisseria meningitidis has resulted in drug resistance development. Sulphonamide resistance in N. meningitidis is caused by alterations in the chromosomal folP gene, coding for DHPS (dihydropteroate synthase). READ MORE

6. 4. Glucose and lipid metabolism in insulin resistance : an experimental study in fat cells

   Author : Jonas Burén; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; adipocyte; insulin resistance; type 2 diabetes; insulin signalling; glucose uptake; insulin; glucose; dexamethasone; insulin receptor substrate; protein kinase B; GLUT4; lipoprotein lipase; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; medicin; Medicine;

   Abstract : Type 2 diabetes is usually caused by a combination of pancreatic β-cell failure and insulin resistance in target tissues like liver, muscle and fat. Insulin resistance is characterised by an impaired effect of insulin to reduce hepatic glucose production and to promote glucose uptake in peripheral tissues. READ MORE

7. 5. Insulin signalling in human adipocytes : mechanisms of insulin resistance in type 2 diabetes

   Author : Anna Danielsson; Peter Strålfors; Fredrik Nyström; Lena Stensson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipocytes; type 2 diabetes; insulin; insulin resistance; insulin signalling; phosphorylation; insulin receptor substrate 1; feedback control; Medical cell biology; Medicinsk cellbiologi;

   Abstract : Prevalensen av fetma ökar drastiskt i stora delar av världen och utgör en stor riskfaktor för att utveckla insulinresistens och typ 2 diabetes. Fettväven kan bli mycket stor om för mycket energi tas upp av kroppen. READ MORE
