A strategy to determine effective diffusion coefficients of proteins in chromatographic gels is presented in this article. An experimental methodology based on frontal liquid chromatography was combined with a numerical methodology based on a mathematical model describing the chromatographic process including the extra-column dispersion, the dispersion due to the packed bed, the external mass tran
Arsenic (As) contamination of rice grains and the generally low concentration of micronutrients in rice have been recognized as a major concern for human health. Here, we investigated the speciation and localization of As and the distribution of (micro) nutrients in rice grains because these are key factors controlling bioavailability of nutrients and contaminants. Bulk total and speciation analys
Introduction: Risedronate, a bisphosphonate for treatment and prevention of osteoporosis, has been shown in several clinical trials to reduce the risk of fractures in postmenopausal women with osteoporosis. The cost-effectiveness of risedronate treatment has previously been evaluated within different country settings using different model and analysis approaches. The objective of this study was to
Multispecies sex pheromone trapping (trapping of more than one species in the same trap) for the pine shoot moth Rhyacionia buoliana , the pine moth, Dendrolimus pini , the nun moth, Lymantria monacha , the pine beauty moth, Panolis flammea and the pine sawflies Diprion pini and Neodiprion sertifer was evaluated. The catch from traps baited with the pheromone of a single species was compared with
Objectives To obtain reference data representative of normal findings at anal endosonography in pregnant and non-pregnant women. To determine intraobserver and interobserver agreement in the detection of endosonographic anal sphincter defects in asymptomatic women. Methods Twenty-five non-pregnant nulliparous women and 25 non-pregnant parous women (age range, 20-67 years) and 47 pregnant women (a
Modern sunscreens contain particles like TiO2 having sizes of 25-70 nm and acting as a reflecting substance. For cosmetic reasons the particle size is minimized. Questions have been raised to what degree these nano particles penetrate the skin barrier, and how they do affect the human. The EU funded project "Quality of skin as a barrier to ultra-fine particles" - NANODERM has started with the purp
Hot luminescence of self-trapped excitons in solid xenon has been investigated in a wide temperature range (from LHeT to 100 K), using X-ray and two-photon excimer laser (ArF and KrF) excitation. Hot luminescence of bulk Xe crystals of volume 2 cm(3) appears to be very sensitive to both the temperature and the quality of the samples, while its highest intensity has been registered under KrF laser
Fiberoptic bronchoscopy with bronchoalveolar lavage and protected specimen brush technique has become an established method for etiologic diagnosis in severe forms of pulmonary infections during recent years. In this study, including 62 bronchoscopies in 53 patients, a standardized program, covering all important pulmonary pathogens, has been evaluated in a heterogeneous group of patients. Results
L-DOPA-induced dyskinesia (LID) is among the motor complications that arise in Parkinson's disease (PD) patients after a prolonged treatment with L-DOPA. To this day, transcriptome analysis has been performed in a rat model of LID [Neurobiol. Dis., 17 (2004), 219] but information regarding the proteome is still lacking. In the present study, we investigated the changes occurring at the protein lev
The rat stomach is rich in endocrine cells. The acid-producing (oxyntic) mucosa contains ECL cells, A-like cells, and somatostatin (D) cells, and the antrum harbours gastrin (G) cells, enterochromaffin (EC) cells and D cells. Although chromogranin A (CgA) occurs in all these cells, its processing appears to differ from one cell type to another. Eleven antisera generated to different regions of rat
Introduction. The aim of the study reported is to examine user discourses identified in the Swedish public library field. The following questions are posed: What user discourses can be found and what characterises them? How are users categorised and what does this categorisation imply? The departure point in this paper is that the ways users are categorised may influence their information behaviou
Popular Abstract in Swedish Sedan Sverige för ungefär tio år sedan blev medlem av Europeiska unionen, änd-rades svensk arbetsrätt så att arbetstagare i vissa fall har en rätt att välja att följa med en verksamhet som övergår till en ny arbetsgivare. Något nytt anställningsavtal skall inte anses ha träffats. De arbetstagare som berörs av verksamhetsövergången har dessutom ett skydd mot att bli uppsWhen Sweden in 1995 became a member of the European Union, Swedish labour legislation was enacted on the safeguarding of employees’ rights in the event of transfer of undertaking. These Swedish rules and regulations are examined. EU law and national law form two parallel systems, which between themselves arrange the legal sources hierarchically, and, as a result of that, the Member States have tra
Popular Abstract in Swedish Sammanfattning Teknik är alltid skapad för en förväntad brukare i ett antaget sammanhang. Inom kommersiell luftfart är dessa antaganden när det gäller design tydliga. Såväl besättning som utrustning är certifierad för en viss typ av operationer i enlighet med flygplanets drifthandbok. Trots denna genomtänkta definition av användare i sitt sammanhang händer det ändå attAbstract Technology is always designed for an assumed user in an assumed context. In commercial aviation, these design assumptions are clearly spelt out in that both crew and equipment are certificated for a specific operation as stated in the aircraft flight manual. Despite this well defined user context, the designed-for and the real contexts often differ enough so that adaptations of working p
To investigate the cause of anomalously bright resonance lines of helium in the Sun, we have studied the magnitude of the enhancements and some proposals made to explain them. Calculations in new semiempirical solar models indicate that the resonance lines of helium are enhanced by factors of 2-5 for He I and between 2 and 9 for He II, depending on the elemental abundances assumed. These enhanceme
The effects of 2,3-butanedione monoxime (BDM) on intracellular Ca2+ transient and cross-bridge function were studied in frog single fibres from the anterior tibialis muscle of Rana temporaria (sarcomere length, 2.2 m; temperature, 24 C). The fluorescent dye fluo-3 was used to monitor the intracellular free calcium concentration ([Ca2+i) during isometric contractions. BDM (15 m M) reduced the ampli
The effect on haemostatic variables by dextran 70, enoxaparin and their combinations, given in doses of 500 ml i.v. and 40 mg s.c. respectively, was studied in a randomised cross-over fashion in twelve healthy male volunteers. Antifactor-IIa activity, antifactor-Xa activity, APTT, factor VIII, vWF, bleeding time and blood counts were analysed over a 24-h period. Dextran alone did not affect antifa
Airway mucus is regulated by many inflammatory mediators such as ILs, TNF-alpha, EGF, PGF2 alpha, LT, and so on. Recently, the relationship between membrane ion channel and Mucus production has been under investigation. The present study aimed to examine whether AQP5 was involved in modulation of mucin expression and secretion in airway submucosal gland cells (SPC-Al). A recombinant plasmid (pShAQ
