2. 1. Cholesterol in T cells : homeostasis, plasma membrane organization and signaling

   Author : Saleemulla Mahammad; Ingela Parmryd; Thomas Harder; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; T cells; Cholesterol; Lipid rafts; Membrane organization; Cholesterol homeostasis; cholesteryl esters; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

   Abstract : The plasma membrane of eukaryotic cells contains cholesterol and glycosphingolipids enriched nanodomains known as lipid rafts; which are believed to exist in a liquid ordered (lo) state. Methyl-beta-cyclodextrin (MBCD) is used to deplete cellular cholesterol and a widespread assumption is that MBCD preferentially targets cholesterol in lipid rafts. READ MORE

4. 2. Haemostatic changes in plasma for transfusion during preparation and storage

   Author : Anna-Maija Suontaka; Karolinska Institutet; Karolinska Institutet; []
   Keywords : transfusion plasma; cold activation; contact system; coagulation; fibrinolysis; citrates; methylene blue; fibrinogen; stability;

   Abstract : The haemostatic quality of plasma for transfusion is liable to be affected by techniques for preparation and storage. We have studied changes in the contact system, coagulation and fibrinolysis under the following conditions: blood drawn into a half-strength citrate anticoagulant solution, virus inactivation of plasma with methylene blue and red light, and plasma storage in the fluid phase.

5. 3. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration

   Author : Parham Ashrafzadeh; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; cancer; cell migration; exocyst complex; exocytosis; FGD5; lipid rafts; plasma membrane; receptor trafficking; VEGFR2;

   Abstract : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. READ MORE

6. 4. Porous polymeric materials for chromatography : Synthesis, functionalization and characterization

   Author : Emil Byström; Knut Irgum; Camilla Viklund; Solomon Tesfalidet; Klaus K Unger; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; porous polymer monolith; pore size distribution; nitrogen sorptiometry; mercury intrusion porosimetry; scanning and transmission electron microscopy; plasma functionalization; Analytical chemistry; Analytisk kemi; Separation methods; Separationsmetoder; Polymer chemistry; Polymerkemi; analytisk kemi; Analytical Chemistry;

   Abstract : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.

7. 5. Chronic Obstructive Pulmonary Disease: Role of Alpha-1-antitrypsin

   Author : Ruta Aldonyte; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Andningsorganen; Respiratory system; monocytes; inflammation; AAT polymerization; AAT; COPD;

   Abstract : The only proven genetic risk factor for Chronic Obstructive Pulmonary Disease (COPD) is an inherited Z (Glu342¡úLys) deficiency of alpha-1-antitrypsin (AAT), a major inhibitor of neutrophil elastase. In vivo, AAT is found in both native (inhibitory) and modified (non-inhibitory) forms. READ MORE
