Stretching DNA in nanochannels is a useful tool for direct, visual studies of genomic DNA at the single molecule level. To facilitate the study of the interaction of linear DNA with proteins in nanochannels, we have implemented a highly effective passivation scheme based on lipid bilayers. We demonstrate virtually complete long-term passivation of nanochannel surfaces to a range of relevant reagen
Aims. - Elevated body mass index (BMI) is associated with an increased risk of type 2 diabetes and cardiovascular disease (CVD). This study explored the association between BMI changes in the first 18 months of newly diagnosed type 2 diabetes and the risk of long-term CVD mortality. Methods. - A total of 8486 patients with newly diagnosed type 2 diabetes and no previous history of CVD or cancer we
Objective: This study evaluated the tolerability and efficacy of inhaled AZD4818, a CCR1 antagonist, in patients with COPD. Methods: This double-blind, placebo-controlled study (NCT00629239) randomised patients with moderate to severe COPD to AZD4818 300 mu g or placebo twice daily via Turbuhaler (R) for 4 weeks. Safety, lung function, functional capacity and health status measures were measured.
The recognition of pathogen-derived structures by C-type lectins and the chemotactic activity mediated by the CCL2/CCR2 axis are critical steps in determining the host immune response to fungi. The present study was designed to investigate whether the presence of single nucleotide polymorphisms (SNPs) within DC-SIGN, Dectin-1, Dectin-2, CCL2 and CCR2 genes influence the risk of developing Invasive
Background: Most epidemiologic studies use traffic at residential address as a surrogate for total traffic exposure when investigating effects of traffic on respiratory health. This study used GIS (Geographical Information Systems) to estimate traffic exposure, not only on residential, but also on workplace address, in addition to survey questions on time spent in traffic during commuting or other
Breast cancer incidence has markedly increased in Western countries for reasons that are not entirely understood. We characterized periodic and age-specific incidence trends of breast cancer in immigrants who migrated from low incidence areas to Sweden. The incidence in immigrants was compared to that in native Swedes and standardized incidence ratios (SIRs) were calculated, based on the Swedish F
Genome-wide association studies (GWAS) have provided strong evidence for inherited predisposition to childhood acute lymphoblastic leukaemia (ALL) identifying a number of risk loci. We have previously shown common SNPs at 9p21.3 influence ALL risk. These SNP associations are generally not themselves candidates for causality, but simply act as markers for functional variants. By means of imputation
The clinical pharmacokinetics of AZD3199, an ultra-long-acting β2-agonist, were investigated in healthy volunteers and patients with asthma or chronic obstructive pulmonary disease (COPD).
Background: Reliable data on familial risks are important for clinical counselling and cancer genetics. Objective: To evaluate familial risks for renal cell carcinomas (RCC) through parental and sibling probands in the largest available dataset. Design, setting, and participants: This study examined the Swedish Family-Cancer Database on 12.2 million individuals, which contains families with parent
Background: Cancer of unknown primary (CUP) is diagnosed at a metastatic stage but no diagnostic effort is spared to find the primary cancers because these will guide the treatment. Consequently, the diagnostic work-up for CUP is more comprehensive than for any other cancer, resulting in detection of second cancers unrelated to CUP. We want to use the detection rate of second cancers as a measure
A recent report of the EuroHeart project has shown that women are still underrepresented in many cardiovascular clinical trials, while important gender differences are present within most areas of heart disease. As the burden of cardiovascular disease is increasing in middle-aged women relative to men, a more profound understanding is needed of the fundamental biological differences that exist bet
Aims To evaluate long-term all-cause risk of mortality in women and men hospitalized for the first time with atrial fibrillation (AF) compared with matched controls. Methods and results A total of 272 186 patients (44% women) <= 85 years at the time of hospitalization with incidental AF 1995-2008 and 544 344 matched controls free of in-hospital diagnosis of AF were identified. Patients were follow
There are substantial differences in accessibility to biological disease modifying antirheumatic drugs (bDMARDs) across countries. The objective of this study was to analyse the impact of patient demographics, disease characteristics and gross domestic product (GDP) on abatacept (ABA) retention in patients with rheumatoid arthritis (RA) treated in clinical practice.
Background: A large number of gene expression profiling (GEP) studies on prognosis of colorectal cancer (CRC) has been performed, but no reliable gene signature for prediction of CRC prognosis has been found. Bioinformatic enrichment tools are a powerful approach to identify biological processes in high-throughput data analysis. Principal Findings: We have for the first time collected the results
Emergency and crisis management research is tightly coupled to practical problems. Yet, within that research tradition, surprisingly little has been done in terms of developing a practice of design research. The present report presents literature surveys aimed at investigating how, and to what extent, such research has been conducted. Although the focus is on command and control problems the mater
Objectives. To investigate the association between maternal characteristics and fetal growth during the third trimester of pregnancy. Methods. Using a population-based perinatal register, 48,809 term singleton pregnancies were identified for which a routine ultrasound examination in the third trimester was performed between 1995 and 2009. Fetal and infant weight, respectively, were expressed as ge
Molecular weight (MW) is one of the most important characteristics of macromolecules. Sometimes, MW cannot be measured correctly by conventional methods like gel permeation chromatography (GPC) due to, for example, aggregation. We propose using single-molecule spectroscopy to measure the average MW simply by counting individual fluorescent molecules embedded in a thin matrix film at known mass con
A genome-wide association study (GWAS) performed on a high-incidence Italian population followed by replications on low-incidence cohorts suggested a strong association of differentiated thyroid cancer (DTC) with single nucleotide polymorphisms (SNPs) at 9q22.33, 2q35, 20q11.22-q12 and 14q24.3. Moreover, six additional susceptibility loci were associated with the disease only among Italians. The p
We present transport measurements in superconductor-nanowire devices with a gated constriction forming a quantum point contact. Zero-bias features in tunneling spectroscopy appear at finite magnetic fields and oscillate in amplitude and split away from zero bias as a function of magnetic field and gate voltage. A crossover in magnetoconductance is observed: Magnetic fields above similar to 0.5 T e
