Objective: To compare two models of learning the pelvic examination (PE) for medical students, with professional patients (PP) or with clinical patients (CP), by measuring perceived distress and learning outcome in terms of skills. Methods: Prospective longitudinal study. Assessments of self-perceived distress on four occasions at the prospect of performing a PE. Evaluation of the learning session
Background. Urban birth, a risk factor for schizophrenia, is more frequent among secondgeneration immigrants. The aim of the current study was to determine whether the increased risk for schizophrenia found in second-generation immigrants is explained by the degree of urbanization of birthplace and/or factors related to parentage, such as geographic origin or history of residence abroad during upb
The water-soluble zwitterionic polythiophene, poly(3-((S)-5-amino-5-carboxyl-3-oxapentyl)-2,5-thiophene) hydrochloride (POWT), is a conjugated polyelectrolyte (CPE) with properties well suited for biochip applications. CPEs readily form hydrogels when exposed to water-based buffer solutions or biomolecule solutions. In this work, we used in situ quartz crystal microbalance with dissipation (QCM-D)
Solvent extracted cashew nut shell liquid (CNSL), conventionally known as natural CNSL, is a mixture of several alkenyl phenols. One of these alkenyl phenols is anacardic acid, which is present at the highest concentration. In view of anticipated industrial applications of anacardic acid, the objective of this work was to isolate anacardic acid from natural CNSL by supercritical carbon dioxide (sc
Coalitions will probably become an increasingly important theme in European Union (EU) politics. The spread of decision making by majority voting promotes coalition-building behaviour. The impending enlargement is predicted to differentiate and polarize policy standpoints within the EU. Increasing levels of policy conflict imply increased propensities for coalition building. Still, the role and na
A fundamental understanding of protein stability and the mechanism of denaturant action must ultimately rest on detailed knowledge about the structure, solvation, and energetics of the denatured state. Here, we use 17O and 2H magnetic relaxation dispersion (MRD) to study urea-induced denaturation of intestinal fatty acid-binding protein (I-FABP). MRD is among the few methods that can provide molec
A subpopulation of neurones in the cerebellar nuclei projects to the inferior olive, the source of the climbing fibre input to the cerebellum. This nucleo-olivary projection follows the zonal and, probably also, the microzonal arrangement of the cerebellum so that closed loops are formed between the neurones in the olive, the cerebellar cortex and the nuclei. The nucleo-olivary pathway is GABAergi
This paper focuses on older peoples’ needs as pedestrians by examining their perceptions of the outdoor environment in both bare-ground and snow/ice conditions. Qualitative and quantitative methods are used, including focus group interviews, participant observations, and questionnaires. The results show that older people consider accessibility/usability issues as very important and that the import
It has been suggested that speakers with an L1 with lexical tones may have an advantage when it comes to perceptually discriminating between different tones in another tone language (Kaan, Wayland, Bao & Barkley, 2007). Other studies in L2-learning show that this is not entirely the case (van Dommelen & Husby 2009, So & Best 2010). A model of typological pitch prominence (Schaefer &
This paper should be read as addendum to Dieckmann et al. (J Theor Biol 241:370-389, 2006) and Parvinen et al. (J Math Biol 67: 509-533, 2013). Our goal is, using little more than high-school calculus, to (1) exhibit the form of the canonical equation of adaptive dynamics for classical life history problems, where the examples in Dieckmann et al. (J Theor Biol 241:370-389, 2006) and Parvinen et al
NURBS (Non-uniform rational B-splines) surfaces are one of the most useful primitives employed for high quality modeling in CAD/CAM tools and graphics software. Since direct evaluation of NURBS surfaces on the GPU is a highly complex task, the usual approach for rendering NURBS is to perform the conversion into Bezier surfaces on the CPU, and then evaluate and tessellate them on the GPU. In this p
Position isomerism is ubiquitous in atmospheric oxidation reactions. Therefore, we have compared surface-active oxygenated amphiphilic isomers (1- and 3-pentanol) at the aqueous surface with surface- and chemically sensitive X-ray photoelectron spectroscopy (XPS), which reveals information about the surface structure on a molecular level. The experimental data are complemented with molecular dynam
The major challenge in the development of new polymer membranes for fuel cells lies currently in the demand for durable membranes that allows fuel cell operation at high temperatures without extensive humidification requirements. Access to these membranes promises important benefits concerning the complexity, cost and performance of the fuel cell system. In this context, membranes functionalized w
Popular Abstract in Swedish Respirationen i både växter och djur kan delas upp i tre delar: glykolysen, citronsyracykeln och elektrontransportkedjan. Glykolysen sker i cytoplasman (cellvätskan), medan citronsyracykeln och elektrontransportkedjan verkar i mitokondrierna. Mitokondrier fungerar som cellernas motorer. De är ungefär lika viktiga för cellen som motorn är för en bil. Mitokondrierna är smThe respiratory chain of plants contains class 2 NAD(P)H dehydrogenases, not present in animals. The functional roles of these enzymes have been elusive for a long time. Two cDNAs, homologous to class 2 NADH dehydrogenase genes of yeast and E. coli, were isolated from potato leaves. The gene products, NDA1 and NDB1, were shown to reside on the internal and external sides of the inner mitochondrial
Background: Flat and depressed colorectal tumours are common in Japan but are very rare or non-existent in Western countries. Aims: To study the occurrence of flat colorectal tumours in a southern Swedish population. Methods: In this prospective study, 371 consecutive European patients were examined by high resolution video colonoscopy combined with chromoendoscopy. The nature of the lesions was
The potential modes of transmission for hepatitis C virus (HCV) infections were studied using a multivariate analysis of risk factor exposure among 51 2nd generation anti-HCV and HCV-RNA positive and matched anti-HCV negative blood donors. The following variables were found to be independently associated with anti-HCV and HCV-RNA positivity: intravenous drug use (IVDU) (p < 0.001), blood transfusi
PURPOSE: To assess whether MR imaging could replace angiography in preoperative evaluation of patients with tetralogy of Fallot and pulmonary atresia with ventricular septal defect (VSD), especially since the surgical correction was done earlier than was previously the rule. MATERIAL AND METHODS: Fourteen patients with tetralogy of Fallot (n = 10) or pulmonary atresia with VSD (n = 4), mean age 7.
Allelopathy, the release of extracellular compounds that inhibit the growth of other microorganisms, may be one factor contributing to the formation and/or maintenance of cyanobacterial blooms. We investigated the allelopathic effects of three cyanobacterial species (Nodularia spumigena, Aphanizomenon flos-aquae and Anabaena lemmermannii) that frequently form mass-occurrences in the Baltic Sea. We
