Background and purpose - In 2003, an enquiry by the Swedish Knee Arthroplasty Register (SKAR) 2-7 years after total knee arthroplasty (TKA) revealed patients who were dissatisfied with the outcome of their surgery but who had not been revised. 6 years later, we examined the dissatisfied patients in one Swedish county and a matched group of very satisfied patients. Patients and methods - 118 TKAs i

We describe a patient with facial cellulitis/erysipelas due to cowpox virus inoculation in the respiratory epithelium of the nose. A cytopathic agent was isolated in cell culture, and the diagnosis of cowpox was confirmed by electron microscopy and polymerase chain reaction. The most likely source of infection was exposure to the family cats. In addition to the severe edematous cellulitis of the f

Purpose of review In this short review we focus on the problems faced by clinicians caused by the changing definitions of polyarteritis nodosa. Recent findings the term polyarteritis nodosa has been used for more than 100 years as a diagnostic term for patients with systemic vasculitis, however, specific vasculitides have been singled out like branches being chopped off a tree. Now, so little is l

Kindling is a model of temporal lobe epilepsy in which repeated electrical stimulations in limbic areas lead to progressive increase of seizure susceptibility, culminating in generalized convulsions and the establishment of a permanent epileptic syndrome. We studied here the effect of stimulations in the thalamic reticular nucleus (TRN) on. the development of seizures and hippocampal hyperexcitabi

The MoviText method has been developed and tested on individuals with absolute central scotomas as a pre-optical reading training method. The ZoomText computer screen magnification software with its DocReader feature has been used in reading training to show the effect of moving the text during reading. The user reads with his or her selected eccentric angleviewing in order to acquire the new ecce

Complex surface reconstructions and surface oxides, in particular, often exhibit complicated atomic arrangements, which are difficult to resolve with traditional experimental methods, such as low energy electron diffraction (LEED), surface X-ray diffraction (SXRD) or scanning tunnelling microscopy (STM) alone. Therefore, ab initio density functional calculations are used as a supplement to the exp

The Anderson-Wilkins (AW) electrocardiographic (ECG) acuteness score complements time from pain onset in prognostic stratification of patients with acute myocardial infarction (AMI). However, for the AW acuteness score to be of practical use in the acute situation, it must be an integral component of a commercial automated ECG analysis program. The objective of this study was to determine the conc

Egle Robineau-Desvoidy is a modest-sized genus of small blackish anthomyiids with a Holarctic and northern Oriental distribution. They are univoltine, interacting closely with the host plants of their seed-feeding larvae, mainly species of willow (Salix), but also poplar (Populus) and false tamarisk (Myricaria) support some species. Summaries are given of adult and larval habits based on published

Homogenates of human blood platelets, but not of red blood cells, have been found to stimulate lipoprotein lipase activity only when assayed against an emulsified triglyceride substrate sonicated for a short period of time. The degree of stimulation was inversely related to the time of sonication of the substrate. Using chylomicrons as substrate no stimulation of lipoprotein lipase activity by pla

Thirteen isidiate taxa in the Teloschistales are briefly discussed, i.e. Letrouitia corallina (Müll. Arg.) Hafellner, L. leprolyta (Nyl.) Hafellner, Caloplaca bassiae (Ach.) Zahlbr., C. granulosa (Müll. Arg.) Jatta, C. herbidella (Hue) H. Magn., C. isidiigera Vězda, C. isidiosa (Vainio) Zahlbr., C. littorea Tavares, C. namibensis Kärnef., C. ochraceofulva (Müll. Arg.) Jatta, C. verruculifera (Vain

Night-migratory songbirds are known to use a magnetic compass [[13]], but how do they detect the reference direction provided by the geomagnetic field, and where is the sensory organ located? The most prominent characteristic of geomagnetic sensory input, whether based on visual patterns [[47]] or magnetite-mediated forces [[8, 9]], is the predicted symmetry around the north-south or east-west mag

The flow around spherical, solid objects is considered. The boundary conditions on the solid boundaries have been applied by replacing the boundary with a surface force distribution on the surface, such that the required boundary conditions are satisfied. The velocity on the boundary is determined by extrapolation from the flow field. The source terms are determined iteratively, as part of the sol

The competition for water between an aqueous lipid phase (L2) and gelatinizing starch was investigated. Differential scanning calorimetry and light microscopy, were used to study the gelatinization behaviour of cassava and potato starch in the thermodynamically stable water containing (i.e. 13% w/w water) oil-continuous L2-phase. This was compared to the gelatinization of the two starches in limit

The present study was designed to replicate previously reported findings of abnormal frontal and/or temporal cerebral blood flow in violent offenders and to control for the influence of major mental disorder (MMD), substance abuse, and current medication. HMPAO-SPECT-CBF and MRI scans from pretrial forensic psychiatric investigations of 21 subjects convicted of impulsive violent crimes were retros
