Biotin synthase was the first example of what is now regarded as a distinctive enzyme class within the radical S-adenosylmethionine superfamily, the members of which use Fe/S Clusters as the sulphur source in radical sulphur insertion reactions. The crystal structure showed that this enzyme contains a [2Fe-2S] cluster with a highly unusual arginine ligand, besides three normal cysteine ligands. Ho
The wood moisture content influences the service life of wood structures since wood is susceptible to decay by rot fungi if it is exposed to high moisture contents during long periods of time. In rain exposed structures, the moisture content close to end grain surfaces and joints can be significantly higher than the average moisture content, but moisture content determinations at such locations re
Multi-dimensional algorithms are hard to implement on classical platforms. Pipelining may exploit instruction-level parallelism, but not in the presence of simultaneous data; threads optimize only within the given restrictions. Tiled architectures do add a dimension to the solution space. With locally a large register store, data parallelism is handled, but only to a dimension. 3-D technologies ar
OBJECTIVE: To assess the reproducibility of the Berg Balance Scale (BBS) and the Single-leg Stance (SLS), and the validity of the SLS as an independent test of upright postural control in patients with chronic stroke. DESIGN: An intra-rater test-retest reproducibility study. The BBS and the SLS were assessed twice, 7 days apart. SETTING: A university hospital. PARTICIPANTS: Fifty individuals
In this mini-review, progress in our understanding of the link between miRNAs and cytokines in inflammatory skin diseases is highlighted with focus on miR-155 in mycosis fungoides (MF). MF is the most common variant of cutaneous T-cell lymphoma (CTCL) and is characterized by malignant T-cell proliferation in a chronic inflammatory environment in affected skin. Recent data show that miR-155 is expr
Autoimmune hepatitis (AIH) is a liver disease that primarily affects women. Many become ill during childbearing age, and medication can be lifelong. Few studies exist on pregnancy outcome in women with AIH.
Sociology of the professions has faced difficulties in delineating and defining the core of its object of study, the concept and phenomenon of profession. Setting out from the so-called French epistemological tradition, this article tries out a new possibility. It is argued that if there are trans-historical elements in professions, they are found at the cognitive side, as a certain reasonably inv
Superficial damage, similar in appearance to salt scaling of concrete, has been observed at the waterline of hydraulic structures, such as hydro power structures, bridge columns, canals and harbours. Progressive damage to the concrete surface results in exposure of coarse aggregate. Deterioration rates of about 1 mm per year have been observed in some cases. A laboratory test method was developed
The catalyst layer (CL) of a proton exchange membrane fuel cell involves various particles and pores that span a wide range of length scales, from several nanometers to a few microns. The success of the CL design depends decisively on understanding the detailed structure in microscale or even in nanoscale. In this paper, the properties of nano-/microstructures are outlined, and the physical and ch
Clinical blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is becoming increasingly valuable in, e.g., presurgical planning, but the commonly used gradient-echo echo-planar imaging (GE-EPI) technique is sometimes hampered by macroscopic field inhomogeneities. This can affect the degree of signal change that will occur in the GE-EPI images as a response to neural
A previous study by the authors using a heated thermal manikin showed that the cooling rates of phase change material (PCM) are dependent on temperature gradient, mass, and covering area. The objective of this study was to investigate if the cooling effects of the temperature gradient observed on a thermal manikin could be validated on human subjects in extreme heat. The subjects wore cooling vest
The process stability of water-in-oil-in-water (W/O/W) double emulsions stabilized with food-grade OSA modified quinoa starch granules was investigated. The effect of oils with differing melting points, as well as the effect of in situ partial gelatinization of the granules, on stability of emulsions was also investigated. The physical stability and release of a tracer (carmine) from the internal
Abstract in UndeterminedAction plans are an important tool for meeting the EU renewable energy targets. Planning of biomass at national level has recently shifted from biomass action plans to renewable energy action plans; the latter still assigning special attention to biomass. A number of regions have also developed or are developing biomass plans. However, even though such plans are to assist t
Knowledge about the existing safety culture in a maritime organization such as in shipping companies or on board ships can enable the formulation of effective interventions to maintain and improve safety culture and safety in the organization. When assessing the safety culture, questionnaires developed for this purpose are often used. This paper proposes a work process that facilitates the analysi
Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants
Food engineering aspects of cooking of meat products in relation to their biophysical properties, such as water- and fat-holding, have been reviewed. Moreover, some of the new emerging, mild cooking technologies, such as high pressure and electro-based heating (radio frequency cooking and ohmic heating) have been discussed in relation to the biophysical properties of the meat products treated. The
The abuse of flunitrazepam (FZ) compounds is worldwide, and several studies have reflected on the consequences with regard to violence, aggression and criminal lifestyle of FZ users. Criminals take high doses of FZ or some other benzodiazepines to "calm down" before the planned crime. There is support from earlier studies that most likely, all benzodiazepines may increase aggression in vulnerable
