The cyp102A2 and cyp102A3 genes encoding the two Bacillus subtilis homologues (CYP102A2 and CYP102A3) of flavocytochrome P450 BM3 (CYP102A1) from Bacillus megaterium have been cloned, expressed in Escherichia coli, purified, and characterized spectroscopically and enzymologically. Both enzymes contain heme, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) cofactors and bind a vari
BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE
The present study is included in a project with the aim to develop attractants from food odors for trapping female moths. Males and mated, but not unmated, females of Ephestia cautella and Plodia interpunctella were attracted by odors of three different chocolate products in flight tunnel experiments. Chocolate containing nut or rum elicited upwind flight and landing responses. Extracts of the cho
In an experiment with a factorial design, the following aspects were scrutinized: the impact on disintegration time and crushing strength caused by the loss-on-drying of the granulation; the granule-size distribution; the lubricant concentration; the compression force; and the pre-compression. Both with regard to disintegration time and crushing strength, these factors were found to have a signifi
This paper discusses recent advances that have been made in the field of psychometrics, specifically, the application of Rasch analysis to the instrument development process. It emphasizes the importance of assessing the fundamental scaling properties of an instrument prior to consideration of traditional psychometric indicators. The paper introduces Rasch analysis and shows how it has been applie
The single-channel activity of rabbit skeletal muscle ryanodine receptor (skeletal RyR) and dog cardiac RyR was studied as a function of cytosolic [Ca2+]. The studies reveal that for both skeletal and cardiac RyRs, heterogeneous populations of channels exist, rather than a uniform behavior. Skeletal muscle RyRs displayed two extremes of behavior: 1) low-activity RyRs (LA skeletal RyRs, approximate
This article aims to analyse how innovative, individual actions influence the evolution of local industries according to three stages. When discussing the evolution of industries or economies, the concept of path dependency is often a central element. Its vague nature makes it however difficult to be used as an interpretative lens when studying the evolution of local industries. In order to limit
l-DOPA-induced dyskinesia (LID) is a major complication of the pharmacotherapy of Parkinson's disease. Emerging approaches to the treatment of LID include negative modulation of metabotropic glutamate receptor type 5 (mGluR5) and positive modulation of serotonin receptors 5-HT1A/1B. We set out to compare the efficacy of these two approaches in alleviating the dyskinesias induced by either l-DOPA o
Water sorption calorimetry has been used for characterization of 2D hexagonally ordered mesoporous silica SBA-15. Experimental data on water sorption isotherm, the enthalpy, and the entropy of hydration of SBA-15 are presented. The results were compared with previously published results on MCM-41 obtained using the same technique. The water sorption isotherm of SBA-15 consists of four regimes, whi
Satellite sensor-derived data are suitable for regional estimations of several important biophysical variables. Data with a finer spatial resolution should improve regional estimations of GPP (gross primary productivity), since they better capture the variation in a heterogeneous landscape. The main objective of this study was to investigate if MODIS 500 m reflectance data can be used to drive emp
We present a study in which the intrawall porosity and primary mesoporosity. of SBA-15 are independently controlled by modifying the strength of the molecular interaction that governs the formation of the material. The interactions are targeted at specific times during the process of formation, which results in selective tuning of the porosity, while other characteristics of the SBA-15 material ar
In this study latent heat flux (E) measurements made at 65 boreal and arctic eddy-covariance (EC) sites were analyses by using the Penman-Monteith equation. Sites were stratified into nine different ecosystem types: harvested and burnt forest areas, pine forests, spruce or fir forests, Douglas-fir forests, broadleaf deciduous forests, larch forests, wetlands, tundra and natural grasslands. The Pen
Experimental and theoretical study of the 3d photoionization and subsequent Auger decay of initially neutral atomic germanium is presented. The features of the high-resolution photoelectron and Auger electron spectra are interpreted with the aid of multiconfiguration calculations. The binding energies and relative cross sections of the 3d ionized fine-structure states of Ge are given. The complete
The objective of this study has been to create an online system for condition monitoring and diagnosis of a combined heat and power plant in Sweden. The system in question consisted of artificial neural network models, representing each main component of the combined heat and power plant, connected to a graphical user interface. The artificial neural network models were integrated on a power gener
Elastic properties of CaMnO3 are of primary importance in the science and technology of CaMnO3-based perovskites. From X-ray diffraction experiments performed at pressures up to 100 kbar using a diamond-anvil cell to hydrostatically compress our sample, a bulk modulus, K (0), of 1734(96) kbar was obtained after fitting parameters to the third-order Birch-Murnaghan equation of state. Mean field, se
This study investigated patterns and controls of the seasonal and inter-annual variations in energy fluxes (i.e., sensible heat, H, and latent heat, lambda E) and partitioning of the water budget (i.e., precipitation, P; evapotranspiration, ET; discharge, Q; and soil water storage, Delta S) over five years (2001-2005) in a boreal oligotrophic fen in northern Sweden based on continuous eddy covaria
BACKGROUND: Personalized oncology requires molecular analysis of tumor cells. Several studies have demonstrated that cytological material is suitable for DNA analysis, but to the authors' knowledge there are no systematic studies comparing how the yield and quality of extracted DNA is affected by the various techniques used for the preparation of cytological material. METHODS: DNA yield and qualit
