Structure-based protein design offers a possibility of optimizing the overall shape of engineered binding scaffolds to match their targets better. We developed a computational approach for the structure-based design of repeat proteins that allows for adjustment of geometrical features like length, curvature, and helical twist. By combining sequence optimization of existing repeats and de novo desi
Abstract in UndeterminedAlthough the diffusion of fertility behavior between different social strata in historical communities has received considerable attention in recent studies, the relationship between the diffusion of fertility behavior and the diffusion of people (migration) during the nineteenth century remains largely underexplored. Evidence from population registers compiled in the Histo
We present a theoretical study of the absorption of light in periodic arrays of InP nanowires. The absorption in the array depends strongly on the diameter and the length of the nanowires, as well as the period of the array. Nanowires of a length of just 2 Am are able, after an appropriate choice for the other parameters, to absorb more than 90% of the incident energy of TE and TM polarized light,
We investigated the risk associated with crossing the Sahara Desert for migrating birds by evaluating more than 90 journeys across this desert by four species of raptors (osprey Pandion haliaetus, honey buzzard Pernis apivorus, marsh harrier Circus aeruginosus and Eurasian hobby Falco subbuteo) recorded by satellite telemetry. Forty per cent of the crossings included events of aberrant behaviours,
Leukocyte telomere length (LTL) has been regarded as a potential marker of biologic aging because it usually shortens in a predictable way with age. Recently, a growing interest in cardiovascular aging has led to a number of new epidemiologic studies investigating LTL in various disease conditions. Some methodological problems exist because there are different methods available to determine LTL, a
Merkel cell carcinoma (MCC) is a rare type of skin cancer that has a characteristically increased incidence among immunosuppressed subjects. The DNA of Merkel cell polyomavirus (MCV) is regularly found in most MCC tumors. We investigated whether Merkel cell polyomavirus (MCV) infection increases the risk for future Merkel cell carcinoma (MCC). Two large biobank cohorts (Southern Sweden Microbiolog
Human genetics is a powerful tool for discovering causal mediators of human disease and physiology. Cardiovascular diseases with late onset in the lifecourse have historically not been considered genetic diseases, but in recent years the contribution of a heritable factor has been established. More importantly, over the last decade genome-wide association studies (GWASs) have identified many loci
The development of a plasmid-based genetic transformation protocol for Chlamydia trachomatis provides the basis for the detailed investigation of the function of the chlamydial plasmid and its individual genes or coding sequences (CDS). In this study we constructed a plasmid vector with CDS6 deleted (pCDS6KO) from the original Escherichia coli/C. trachomatis shuttle vector pGFP::SW2. pCDS6KO was t
Although protein coding genes occupy only a small fraction of genomes in higher species, they are not randomly distributed within or between chromosomes. Clustering of genes with related function(s) and/or characteristics has been evident at several different levels. To study how common the clustering of functionally related genes is and what kind of functions the end products of these genes are i
Existing database in literature on the adiabatic two-phase frictional pressure drop in evaporative micro/mini-channels were reviewed. The collected database contains 769 data points, covering 12 fluids, for a wide range of operational conditions and channel dimensions. The whole database was analyzed using five existing correlations to verify their respective accuracies. The importance of the Bond
Objectives: To study signs of obstructive airway disease (OAD) in patients with primary Sjögren's syndrome (pSS) using the forced oscillation technique (FOT). Method: Thirty-seven female pSS patients (median age 64, range 38-77 years) without previous physician-diagnosed OAD, participating in a longitudinal follow-up study of pulmonary function, and 74 female population-based controls (median age
ABSTRACT. Callus formation is a critical step for successful fracture healing. Little is known about the molecular composition and mineral structure of the newly formed tissue in the callus. The aim was to evaluate the feasibility of small angle x-ray scattering (SAXS) to assess mineral structure of callus and cortical bone and if it could provide complementary information with the compositional a
Context Agricultural transformation and increased land use intensity often lead to simplified landscapes and biodiversity loss. For animals, one possible mechanism underpinning biodiversity loss in agricultural landscapes is the disruption of movements. The disruption of movements may explain, for example, why butterfly communities in agricultural landscapes are often dominated by generalist speci
Gastrointestinal stromal tumor (GIST) has been considered radiation-resistant, and radiotherapy is recommended only for palliation of bone metastases in current treatment guidelines. No registered prospective trial has evaluated GIST responsiveness to radiotherapy.
OBJECTIVE: To study long-term work disability before and after tumour necrosis factor (TNF)-antagonist therapy in patients with psoriatic arthritis (PsA). METHODS: Using the population-based South Swedish Arthritis Treatment Group Register, we identified 191 patients with PsA (median age 43 years, range 18-58 years, 54% men), who between January 2003 and December 2007 started treatment with adalim
Patients with rheumatoid arthritis (RA), particularly those with severe disease, have increased risk of cardiovascular disease (CVD). Previous studies suggest that endothelial cell activation may contribute to this co-morbidity, and that treatment with tumour necrosis factor (TNF) inhibitors could reduce the risk of CVD in these patients. The aim of this study was to investigate endothelial cell a
The EU is now emerging as a major actor in regional and global peacebuilding. The EU does not perceive conflict as endemic, and develops its policy on the basis that conflict is eminently resolvable if structural issues, needs, social injustice, and inequality are addressed. Yet its peacebuilding project is subject to some significant and familiar contradictions. We identify the basis for what may
Simultaneous contact allergies to Disperse Orange 1, 4-nitroaniline and p-aminodiphenylamine (PADPA), as well as to other disperse azo dyes and to p-phenylenediamine (PPD), have been reported. Cross-reactivity is one of the possible explanations for simultaneous reactions between PPD and disperse azo dyes. Some metabolites from the azo reduction of these disperse azo dyes could be sensitizers, as
Recent research has focused on the different types of compass cues available to ball-rolling beetles for orientation, but little is known about the relative precision of each of these cues and how they interact. In this study, we find that the absolute orientation error of the celestial compass of the day-active dung beetle Scarabaeus lamarcki doubles from 16° at solar elevations below 60° to an e
