Influence of Ethanol on Lipid Membranes: From Lateral Pressure Profiles to Dynamics and Partitioning.

We have combined experiments with atomic-scale molecular dynamics simulations to consider the influence of ethanol on a variety of lipid membrane properties. We first employed isothermal titration calorimetry together with the solvent-null method to study the partitioning of ethanol molecules into saturated and unsaturated membrane systems. The results show that ethanol partitioning is considerabl

Effects of Bulk Colloidal Stability on Adsorption Layers of Poly(diallyldimethylammonium Chloride)/Sodium Dodecyl Sulfate at the Air-Water Interface Studied by Neutron Reflectometry

We show for the oppositely charged system poly(diallyldimethylammonium chloride)/sodium dodecyl sulfate that the cliff edge peak in its surface tension isotherm results from the comprehensive precipitation of bulk complexes into sediment, leaving a supernatant that is virtually transparent and a depleted adsorption layer at the air/water interface. The aggregation and settling processes take about

Hirschsprung´s Disease & Gastroesophageal Reflux. Aspects on Two Gastrointestinal Motility Disorders in Childhood

Popular Abstract in Swedish Det enteriska nervsystemet (ENS) utgör mag-tarmkanalens eget nervsystem, ibland refererat till som “the second brain” då det uppvisar stora likheter med det centrala nervsystemet (CNS). Rubbningar i ENS ger bland annat störningar i tarmens motorik. Denna avhandling handlar om två sjukdomar i mag-tarmkanalen hos barn som bägge är uttryck för en rubbad motorik; HirschspruGastrointestinal motility disorders are common in childhood and in this thesis we look at two of them, i.e. Hirschsprung´s Disease (HD) and gastroesophageal reflux disease (GERD) in five different studies. HD is a congenital disease characterized by an abscence of ganglion cells in myenteric and submucous ganglia, most commonly in the distal part of the large bowel. In Paper I, we have studied th

The Prognostic Significance of Tryptophanyl-tRNA Synthetase in Colorectal Cancer

Background: Tryptophanyl-tRNA synthetase (TrpRS) is an aminoacyl-tRNA synthetase involved in protein synthesis and regulation of RNA transcription and translation and is an inhibitor of angiogenesis. TrpRS has been shown to be differentially expressed in colorectal cancer (CRC) and has thus been identified as a potential prognostic marker. The aim of this study was to analyze the correlation of Tr

Abstract in German Die Reaktionen auf die NS-Rassenpolitik in Schweden sind insofern besonders interessant, da Schweden weder besetzt, noch aliiert, noch kriegführend war. Die Folgen der deutschen Politik waren darum auf der einen Seite selbstverständlich viel indirekter als in den stärker unmittelbar berührten Staaten. Andererseits haben neueste Untersuchungen ergeben, dass viele Menschen auch im

A Pill for the Ill? Patients’ Reports of Their Experience of the Medical Encounter in the Treatment of Depression

Background Starting in the 1960s, a broad-based patients’ rights movement began to question doctors’ paternalism and to demand disclosure of medical information, informed consent, and active participation by the individual in personal health care. According to scholars, these changes contributed to downplay the biomedical approach in favor of a more patient-oriented perspective. The Swedish non-p

Coding of procedures documented by general practitioners in Swedish primary care-an explorative study using two procedure coding systems

Background: Procedures documented by general practitioners in primary care have not been studied in relation to procedure coding systems. We aimed to describe procedures documented by Swedish general practitioners in electronic patient records and to compare them to the Swedish Classification of Health Interventions (KVA) and SNOMED CT. Methods: Procedures in 200 record entries were identified, co

Male inguinal hernia repair with mesh. Short- and long-term results and the question of infertility.

Popular Abstract in Swedish Med stigande ålder försvagas våra vävnader. Om bukväggen i ljumsken blir för svag, så kan bukinnehållet pressas ut genom svagheten. Detta kallas för ljumskbråck. Sjukdomen är mycket vanligare hos män och drabbar alla åldrar. Ju äldre man är, desto vanligare att man drabbas av ett ljumskbråck. Man upplever då, framför allt vid ansträngning, en oftast rörlig och ibland smBackground: In the nineties, the patients with inguinal hernias were exposed to several newly developed repair techniques using alloplastic mesh prosthesis. Although the scientific knowledge was limited, the new techniques were rapidly introduced due to surgical enthusiasm, but also by an eagerness to reduce the recurrence rate and to shorten the time to recovery. When the first study of this thes

Clinical and Genetic Determinants of Progression of Type 2 Diabetes: A DIRECT Study

OBJECTIVETo identify the clinical and genetic factors that explain why the rate of diabetes progression is highly variable between idividuals following diagnosis of type 2 diabetes.RESEARCH DESIGN AND METHODSWe studied 5,250 patients with type 2 diabetes using comprehensive electronic medical records in Tayside, Scotland, from 1992 onward. We investigated the association of clinical, biochemical,

Safety of thalidomide in newly diagnosed elderly myeloma patients: a meta-analysis of data from individual patients in six randomized trials

Treatment with melphalan-prednisone-thalidomide improves the outcome of patients with multiple myeloma and is now considered a standard of care for patients not eligible for transplantation. However, this treatment is a major source of morbidity. A meta-analysis of data from individual patients (n=1680) in six randomized trials was performed, comparing the effects of melphalan-prednisone-thalidomi

Multivariable Optimization-Based Model Reduction

In this technical note we introduce a multivariable extension of a recently proposed model reduction algorithm for linear time-invariant systems. Reduced models are found by solving a convex. optimization problem with Linear Matrix Inequality constraints given a state space model or frequency samples of a model. In order to illustrate the method we apply it to a large-scale model of a deformable m
