BACKGROUND: Breast cancer risk for postmenopausal women is positively associated with circulating concentrations of oestrogens and androgens, but the determinants of these hormones are not well understood. METHODS: Cross-sectional analyses of breast cancer risk factors and circulating hormone concentrations in more than 6000 postmenopausal women controls in 13 prospective studies. RESULTS: Concent
Background: The co-morbidity of cystic fibrosis (CF) and celiac disease (CD) has been reported sporadically since the 1960s. To our knowledge, this is the first time a systematic screening is performed in a large cohort of CF patients. Methods: Transglutaminase-IgA (TGA), endomysium-IgA (EMA) and total IgA in serum were measured in 790 CF patients (48% females, 86% with pancreatic insufficiency).
Objective: The aim of the first Nordic mantle cell lymphoma (MCL) protocol was to study the clinical significance of an augmented CHOP induction chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) and to examine the prognostic significance of stem cell contamination rates in newly diagnosed patients with MCL. Patients and methods: Forty-one newly diagnos
BACKGROUND. The aim was to study the clinicopathological characteristics, treatment, and outcome of liposarcoma in an unselected, population-based patient sample, and to establish whether treatment was according to the Scandinavian Sarcoma Group (SSG) treatment guidelines. METHODS. The SSG Pathology Board reviewed 319 liposarcoma cases reported between 1986 and 1998. After the review, 237 patients
Popular Abstract in English Proteins are a big biological molecules that help cells to function. Proteins play important roles in all vital processes of the living cell, transporting molecules, speeding up chemical reactions, supporting structure of other proteins and the cell, helping the cell to move. Various disease-causing agents (e.g. bacteria and viruses) are constant threat to us. It is thMost drugs act on biomacromolecules. The Cost of developing new drugs is very high. A method to accurately predict binding affinities would be very useful. We have studied molecular mechanics with generalised Born and surface--area solvation (MM/GBSA) and alchemical free energy perturbation methods (FEP) for use in calculations of ligand binding energies. For the MM/GBSA method we have tested: Ca
Objective: The aim of this study was to investigate how maternal cell-free fetal hemoglobin and heme impact the scavenger enzyme systems Hemopexin and Heme Oxygenase-1 in patients with preeclampsia (PE). The secondary aims were to evaluate these proteins as biomarkers for severity of the clinical manifestation i.e. hypertension, in early- and late onset PE. Material and methods: Plasma samples tak
Previous reports have suggested a role for polycyclic aromatic hydrocarbons in the pathogenesis of atherosclerosis. Therefore, the effects of benzpyren (BP) and dimethylbenzanthracene (DMBA) on the arterial smooth muscle cell (SMC) in culture were studied. DMBA increased the proliferation of bovine and rabbit SMC but not of human embryonal fibroblasts or human SMC. BP did not significantly influen
A high survival rate of grafted dopamine neurons is crucial for reversing neurological deficits following brain tissue transplantation in Parkinson's disease. For unknown reasons the survival rate of transplanted dopamine neurons is only around 10% in experimental animals. The hypothesis that oxidative stress causes the loss of transplanted neurons was tested by grafting neurons from transgenic mi
Request PermissionsThis paper analyzes subband beamforming schemes mainly aimed at speech enhancement and acoustic echo suppression applications such as hands-free telephony for both mobile and office environments, Internet telephony and video conferencing. Analytical descriptions of both causal finite-length and noncausal infinite-length subband microphone array structures are given. More specifi
Background: We have previously shown promising results 2 years after Roux-en-Y gastric bypass surgery, within the Adolescence Morbid Obesity Surgery study (AMOS). The aim of the current study was to describe the 2-year outcome in cardiorespiratory fitness, body composition, and functional capacity in the Stockholm subset of the AMOS study. Methods: Forty-one adolescents (10 male, 31 female, age 14
We present and study a minimal structure-based model for the self-assembly of peptides into ordered β-sheet-rich fibrils. The peptides are represented by unit-length sticks on a cubic lattice and interact by hydrogen bonding and hydrophobicity forces. Using Monte Carlo simulations with >10^{5} peptides, we show that fibril formation occurs with sigmoidal kinetics in the model. To determine the mec
Evolution of metallic properties of free and initially neutral nanoscale Bi clusters has been studied using synchrotron radiation excited photoelectron spectroscopy. The 4f and 5d core as well as the valence levels have been probed. The cross-level analysis indicates metallic properties in Bi clusters in the observed size range from 0.5 nm to 1.4 nm. The behavior of the core-level and valence bind
OBJECTIVE: Heart rupture is a devastating complication to negative pressure wound therapy in cardiac surgery. Also, reduced cardiac output during negative pressure wound therapy has been reported. The present study aimed to examine the effects of negative pressure wound therapy on the position of the heart in relation to the thoracic wall using magnetic resonance imaging in a porcine sternotomy wo
Popular Abstract in Swedish Den här avhandlingens syfte var att undersöka hur väl barn kan återberätta en bevittnad händelse och vid behov identifiera en misstänkt gärningsman i en ”lineup”, en vittneskonfrontation där en misstänkt tillsammans med fem personer som liknar den misstänkte presenteras på fotografier. Tre studier genomfördes. Den första studien undersökte barns förmåga att återberätta Through centuries, witnesses to crimes have played an important role for the police to get a conviction of the culprit. This dissertation examined how accurate children are as witnesses of events and when participating in lineups. In Study 1, participants were tested with free recall and focussed questions. Children aged 8-9 years, 11-12 years and adults in two experiments witnessed film events
The exact incidence and prevalence of Budd-Chiari syndrome (BCS) is unknown in the general population. Published reports differ in terms of the clinical characteristics, effects of therapy and survival. To investigate the epidemiology, clinical presentation and survival in patients with BCS. Retrospective multicentre study in Sweden reviewing the medical records of all patients with BCS 1986-2003,
In the present study, we investigate degradable anionic dendritic nanogels (DNG) as carriers for antimicrobial peptides (AMPs). In such systems, the dendritic part contains carboxylic acid-based anionic binding sites for cationic AMPs, whereas linear poly(ethylene glycol) (PEG) chains form a shell for promotion of biological stealth. In order to clarify factors influencing membrane interactions of
The International Bladder Cancer Group (IBCG) has proposed a prognostic model for intermediate risk (IR) non-muscle invasive bladder cancer (NMIBC) for clinical decision-making. We applied the IBCG IR model in a population-based Swedish setting in patients with primary IR NMIBC diagnosed 2013-2014 in BladderBaSe 2.0. Patients were stratified into low-risk (unifocal and tumour size < 3 cm) and inte
Objectives: Hepatic arterial treatment (HAT) for liver metastases in patients with metastatic breast cancer (MBC) has only been investigated in few studies. Materials and methods: Two phase II trials were initiated simultaneously to evaluate capecitabine in combination with oxaliplatin in patients with MBC and liver metastases. These two trials are reported together. Continuous capecitabine (1300
BACKGROUND: Recent studies have suggested that reactive oxygen species may be involved in the development of diabetic retinopathy. METHODS: Nitro blue tetrazolium (NBT) staining, a marker of reductants which may be induced by free radicals such as superoxide, and catalase activity, as an indirect measure of hydrogen peroxide (H2O2) generation, were studied in the rat retina in three conditions kno
