Electrochemical properties of two multiforms of laccase from Trametes pubescens basidiomycete (LACI and LAC2) have been studied. The standard redox potentials of the T1 sites of the enzymes were found to be 746 and 738 mV us. NHE for LACI and LAC2, respectively. Bioelectroreduction of oxygen based on direct electron transfer between each of the two forms of Trametes pubescens laccase and spectrogr
Flow cytometric (FCM) DNA ploidy measurements on frozen fresh samples of soft tissue sarcomas were compared with the corresponding analyses on preoperative fine needle aspirates and postoperative formalin-fixed archival tissues from the same tumors. A concordance in ploidy status (diploid versus non-diploid) was obtained for 63% of the fresh tissue-fine needle aspiration (FNA) sample comparisons a
This study aimed to describe and analyse self-rated health in relation to sense of coherence and socioeconomic and health-related factors and to explore the associations between self-rated health and these factors in order to identify health resources and health limitations in a group of healthy middle-aged women. Healthy middle-aged women from a defined geographical area in Southern Sweden ( n =5
Popular Abstract in Swedish Laser Doppler metoder avsedda för mätning av blodflöde baserar sig på det faktum att fotoner skiftar i våglängd när de träffar blodkroppar i rörelse. Den förändrade våglängden registreras och signalen bearbetas varefter resultatet uttrycks i en godtycklig enhet och anses utgöra ett mått på blodflöde. Laser Doppler Perfusion Monitoring (LDPM) är en metod med vilken blodThe operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. Laser Doppler perfusion
A theoretical model is established for diffusion of different types of ions in pore solution of concrete and the coupling to moisture flow and moisture content. Mass exchanges between ions in pore solution and solid hydration products in the concrete are also considered. The basic concepts behind the so-called mixture theory are used.
Gyrodinium dorsum Kofoid responds photophobically to flashes of blue light. The photophobic response consists of a cessation of movement (stop-response). Without background light and after a flash fluence above 10 J m-2, 75-85% of the cells show a stop-response, only only 50% of the cells show this response at 5 J m-2. With a flash fluence of 5 J m-2, background light of different wavelengths eith
The surface electronic structure of cleaved single crystals of the organic superconductor kappa-(ET)(2)Cu(NCS)(2) has been studied using photoemission microscopy. Two types of cleaved surfaces were observed, displaying different valence band photoemission spectra and different spectral behavior near the Fermi level, EF. In particular, spectra from one surface type display relatively broad spectral
We prove the existence of positive solutions to the scalar equation y"(x) + F(x, y, y') = 0. Applications to semilinear elliptic equations in exterior domains are considered. (c) 2005 Elsevier Ltd. All rights reserved.
Background: Pharmacodynamic studies of antibiotics have attracted great interest in recent years. However, studies on the pharmacodynamics of different antibiotics against Clostridium difficile are scarce. Methods: The postantibiotic effects (PAE) and the postantibiotic sub-minimum inhibitory concentration (MIC) effects (PA SME) of vancomycin, metronidazole and fusidic acid were investigated by vi
Mg-chelatase catalyzes the insertion of Mg2+ into protoporphyrin IX at the first committed step of the chlorophyll biosynthetic pathway. It consists of three subunits: I, D, and H. The I subunit belongs to the AAA protein superfamily ( ATPases associated with various cellular activities) that is known to form hexameric ring structures in an ATP-dependant fashion. Dominant mutations in the I subuni
This paper describes a methodology for estimating the true internal costs of construction waste, aimed at promoting environmentally friendly waste management. The study employs cost-benefit analysis, contribution margin analysis, the polluter-pays principle and a mathematical model: the model for Efficient Use of Resources for Optimal Production Economy (EUROPE), which has been introduced previous
Multi-electron production is studied at high electron transverse momentum in positron- and electron-proton collisions using the H1 detector at HERA. The data correspond to an integrated luminosity of 115 pb(-1). Di-electron and tri-electron event yields are measured. Cross sections are derived in a restricted phase space region dominated by photon-photon collisions. In general good agreement is fo
The neuropeptide vasoactive intestinal polypeptide (VIP), which is found in a population of cholinergic parasympathetic neurons in the airways, has no effects per se on mucociliary activity. In order to test the hypothesis that VIP may modulate cholinergic regulation of the mucociliary system, VIP was infused intraarterially (8.4 pmol/kg/min), and the response to challenges with methacholine in th
