To apply and compare magnetic resonance imaging (MRI) metal artifact reducing sequences (MARS) including subtraction imaging after contrast application in patients with metal-on-metal (MoM) hip prostheses, investigate the prevalence and characteristics of periprosthetic abnormalities, as well as their relation with pain and risk factors.
BACKGROUND: Microvascular dysfunction, characterized by edema formation secondary to increased blood-brain barrier (BBB) permeability and decreased blood flow, contributes to poor outcome following brain trauma. Recent studies have indicated that statins may counteract edema formation following brain trauma but little is known about other circulatory effects of statins in this setting. The objecti
The biosphere emits volatile organic compounds (BVOCs) which, after oxidation in the atmosphere, can partition on the existing aerosol population or even form new particles. The large quantities emitted provide means for a large potential impact on both aerosol direct and indirect effects. Biogenic responses to atmospheric temperature change can establish feedbacks even in rather short timescales.
Animals with color vision use color information in intra- and interspecific communication, which in turn may drive the evolution of conspicuous colored body traits via natural and sexual selection. A recent study found that the transparent wings of small flies and wasps in lower-reflectance light environments display vivid and stable structural color patterns, called "wing interference patterns" (
Certain purified indigestible carbohydrates such as inulin have been shown to stimulate gut-derived hormones involved in glycaemic regulation and appetite regulation, and to counteract systemic inflammation through a gut microbiota-mediated mechanism. Less is known about the properties of indigestible carbohydrates intrinsic to food. The aim of this study was to investigate the possibility to affe
We propose a novel interconnector design, termed bi-layer interconnector, for solid oxide fuel cells (SOFCs). It can disturb the fuel gas and air on the planes normal to the SOFC three-phase-boundary (TPB) layer. In this paper, a two-dimensional half-cell model is developed to study the concentration overpotentials in the fuel side of the SOFC stack with conventional and novel bi-layer interconnec
The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both c
Students’ experiences and perceptions of good teaching and understanding in literature and physics during one school year were investigated through in-depth interviews with students in eight Greek high school classes in the first, second and third grade. The pedagogical quality of in-depth teaching and understanding of subject matter, as described by the students, was investigated. Students’ feeli
Aim: This study aims to describe how mothers spend the period of time between being diagnosed with a dead baby in utero and the induction of the delivery. Material and Methods: Data were collected using a web questionnaire. Five hundred and fifteen women who had experienced a stillbirth after the 22nd week of gestation answered the open question: 'What did you do between the diagnosis of the child
Matrix metalloproteinases (MMPs) play an important role in the pathological processes of degradation of extracellular matrix and destruction of basement membrane, which leads to tumor invasion and metastasis. In the present study, we investigated membrane-type 2 MMP (MT2-MMP) expression pattern in esophageal cancer tissues collected from 103 patients, and explored MT2-MMP expression pattern in cor
We used two methods, namely stamping and printing, to transfer arrays of epitaxial gallium phosphide (Gap) nanowires from their growth substrate to a soft, biodegradable layer of polycaprolactone (PCL). Using the stamping method resulted in a very inhomogeneous surface topography with a wide distribution of transferred nanowire lengths, whereas using the printing method resulted in an homogeneous
A critical aspect of science is the clear communication of complicated matters. However, language is often ambiguous, and the message can get lost in the telling. In particular, genetic terms can have different meanings for different people. Here, I discuss this problem and suggest remedies to clarify the message.
Culprit coronary artery assessment in the triage ECG of patients with suspected acute coronary syndrome (ACS) is relevant a priori knowledge preceding percutaneous coronary intervention (PCI). We compared a model-based automated method (Olson method) with an expert-rule based method for the culprit artery assessment.
There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit
Template-capped TiO2 nanostructures have been synthesized. In certain template conditions, TiO2 hexagons are found to form. These hexagonal structures can be effectively sensitized by fluorescein dye without any change in the protonation state of the dye. Bare TiO2 nanoparticles are not so useful for sensitization with dyes like fluorescein as they alter the dye protonation state. The novelty of t
Background As moderate to severe psoriasis is a systemic disease with large effects on health-related quality of life, generic measures that include overall health, not only skin involvement, are necessary. Knowledge about the relationship between the generic preference-based EuroQol 5D (EQ-5D) and dermatology-specific measures in psoriasis is limited. Objectives To analyse EQ-5D, the Dermatology
The debate on non‐human future‐oriented cognition has long revolved around the question whether such cognition at all occurs. Closer inspection reveals just how much cognition in general—down to its simplest forms—is geared toward predicting the future in a bid to maintain homeostasis and fend off entropy. Over the course of life's existence on Earth, evolution and natural selection have, through
Objective: The Lund Integrated Medicines Management (LIMM) model improves the patient medication process and reduces primary care contact and rehospitalisation. The objective was to evaluate the quality of medication management activities and the time spent on these activities using the LIMM model in hospital and primary care. Methods: Questionnaires were distributed to physicians and nurses in h
ALOX12 and ALOX15 encode arachidonate lipoxygenases which produce lipid metabolites involved in inflammatory processes. Metabolites generated by ALOX12 and ALOX15 can activate the expression of the potent pro-inflammatory cytokine IL-6, and produce endogenous ligands for PPARG. In this study, polymorphisms in ALOX12, ALOX15, IL6 and PPARG were investigated for association with bone properties in y
The aim of this study was to assess the psychometric properties of a Swedish version of the General Self-Efficacy Scale (GSE) in stroke survivors. The GSE was administered by the same assessor on two occasions 3 weeks apart with 34 stroke survivors (21 men, 13 women; mean age=68.1 years) 6-10 months after stroke. Psychometric properties including targeting and scaling assumptions, and several reli
