Background: Photoallergic contact dermatitis from ketoprofen has been recognized since the mid-1980s. Skin reactions have been reported to continue weeks after discontinuation of ketoprofen. One reason for this could be residual ketoprofen in the skin, which has been shown in a skin biopsy specimen. Objective: We sought to report on 3 cases of photoallergic contact dermatitis from ketoprofen in to

Early B-cell factor (EBF) is a DNA binding protein required for early B-cell development. It activates transcription of several B-cell-specific genes, including the {lambda}5 gene, which encodes a protein necessary for signaling by the pre-B-cell receptor. In an effort to understand the mechanism by which EBF activates transcription, we examined its interaction with the coactivator protein p300/CB

It is known for a fact that the far-field boundary causes expensive computer calculations, when applying the finite element method to Maxwells equations. The reason is of course that a magnetic potential of some kind must be forced to zero at an appropriate distance from the disturbance, in electromagnetics the conductor. Various methods have been examined to reduce the cost of these calculations.

Complex intensity-modulated radiation therapy (IMRT) treatment plans require rigorous quality assurance tests. The aim of this study was to independently verify the delivered dose inside the patient in the region of the treatment site. A flexible naso-gastric tube containing thermoluminescent dosimeters (TLDs) was inserted into the oesophagus via the sinus cavity before the patient's first treatme

The presence of many laminin receptors of the β1 integrin family on most cells makes it difficult to define the biological functions of other major laminin receptors such as integrin α6β4 and dystroglycan. We therefore tested the binding of a β1 integrin-null cell line GD25 to four different laminin variants. The cells were shown to produce dystroglycan, which based on affinity chromatography boun

The increasing prevalence of obesity in the Western world has stimulated an intense search for mechanisms regulating food intake and energy balance. A number of appetite-regulating peptides have been identified, their receptors cloned and the intracellular events characterized. One possible energy-dissipating mechanism is the mitochondrial uncoupling of ATP-synthesis from respiratory chain oxidati

The purpose of this work was to study image effects due to time-varying contrast medium concentration in contrast-enhanced three dimensional (3D) magnetic resonance angiography (MRA) images. Two different simulation models (1D and 3D) and two different contrast medium variation schemes were used. Phantom measurements were also performed. Experiments were performed for several different bolus timin

Acute neurodegeneration in man is encountered during and following stroke, transient cardiac arrest, brain trauma, insulin-induced hypoglycemia and status epilepticus. All these severe clinical conditions are characterized by neuronal calcium overload, aberrant cell signaling, generation of free radicals and elevation of cellular free fatty acids, conditions that favor activation of the mitochondr

The purpose of this study was to determine how image quality in breast tomosynthesis (BT) is affected when acquisition modes are varied, using human breast specimens containing malignant tumors and/or microcalcifications. Images of thirty-one breast lumpectomy and mastectomy specimens were acquired on a BT prototype based on a Mammomat Novation (Siemens) full-field digital mammography system. BT i

We present an improved measurement of the double helicity asymmetry for pi(0) production in polarized proton-proton scattering at root s=200 GeV employing the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The improvements to our previous measurement come from two main factors: Inclusion of a new data set from the 2004 RHIC run with higher beam polarizations than the earlier run an

EF-hand Ca2+-binding proteins participate in both modulation of Ca2+ signals and direct transduction of the ionic signal into downstream biochemical events. The range of biochemical. functions of these proteins is correlated with differences in the way in which they respond to the binding of Ca2+. The EF-hand domains of calbindin D-9k and calmodulin are homologous, yet they respond to the binding

High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work, the high-spin structure of Er-156,Er-157,Er-158 has been studied using the Gammasphere spectrometer. The subject of triaxi

Huntington’s disease (HD) is a hereditary disorder characterized by personality changes, chorea, dementia and weight loss. The cause of this weight loss is unknown. The aim of this study was to examine body weight changes and weight-regulating factors in HD using the R6/2 mouse model as a tool. We found that R6/2 mice started losing weight at 9 weeks of age. Total locomotor activity was unaltered

In this article the caring power in the Swedish probation service is discussed. By exploring the history of probation, formed since the early 19 th century, the structure that is constructed through human interaction and that defines the role of helper and helped is shown. Within this structure, different interpretations exist and different stories are told. This variation is highlighted through s

Core-level spectroscopy and valence-band photoelectron spectroscopy were used to study the Ge(100)2×1 surface dosed with 0.5–100 L H2O at 160 K. It is determined that H2O adsorbs molecularly at 160 K and forms ice. The H2O molecules dissociate into H and OH radicals on the Ge(100)2×1 surface when the sample is heated to 300 K. A simple adsorption model that accounts for the calculated H and OH cov

Problems related to the urogenital tract are common in elderly women. Control of micturition is often impeded and questionnaire-based studies have reported a prevalence of poor control of micturition in about 30% of postmenopausal women. In an ongoing cohort comprising women born between 1935 and 1945, an interim analysis was performed in 1800 women based on an interview and questionnaire. The pre

The objectives are to relate species distributions among 110 non-fertilized grassland ('dry meadow') sites in southeastern Sweden to soil chemical, physical, exposure and management variables using correlation, stepwise regression and factor (PCA) analysis based on quantitative data. It was suggested that soil acidity variables (pH, base saturation, exchangeable Ca, Al, Mn,and Fe), P, K, Mg, and N
