Arthrodesis is usually performed with joint resection or at least with removal of cartilage. Our recent experience with successful fusion in all 11 rheumatoid ankles treated only with percutaneous fixation questions the necessity of debridement of the joint before arthrodesis. In this rabbit study we tested the hypothesis that joints fuse because of rigid fixation. 9 skeletally mature loop-ear dwa

Yrast states of Sb-106 have been investigated in the Fe-54(Ni-58, alpha pn) reaction using in-beam gamma-spectroscopic methods and in the Cr-50(Ni-58,pn) reaction performing delayed gamma and conversion electron studies. A new isomeric state was found at 103 keV with t(1/2) = 232(21) ns. The number of start's and transitions in the proposed level scheme have been doubled. The experimental results

This review examines two books by Ingemar Rådberg: his dissertation En predikant på Galejan. Om Jacob Wallenbergs predikningar; and his edition of Jacob Wallenberg, Samlade skrifter del III.

Human cytomegalovirus (HCMV)-infected cells express a virus-encoded receptor that is able to bind the Fc part of IGG: Some basic binding properties of this Fc receptor (FcR) have been examined. The affinity constant (K(a)) for human IgG Fc fragment in its interaction with acetone-fixed, HCMV-infected human embryonic lung fibroblasts was estimated to be around 2 x 10(8) M(-1) and the number of bind

Restricted diffusion of water in a highly concentrated w/o emulsion was studied using pulsed field gradient spin echo techniques. The standard two-pulse version of this technique, suitable for analysis in the time domain, fails to investigate the short time-scale for diffusion inside a single emulsion droplet with radius 0.7 mum. With a pulse-train technique, originally introduced by Callaghan and

In this study we have investigated the image quality of lumbar spine radiographs taken after recording technical and physical parameters. Two technical parameters were altered, tube voltage (70 kV and 90 kV for the anteroposterior (AP) projection and 77 kV and 95 kV for the lateral projection) and sensitivity of the film-screen system (sensitivity class 400 and 600). In total, 85 images were inclu

Objective: The aim of this study was to describe factors that influenced first-time mothers’ choice of and experiences during the first postnatal week, after early discharge without a domiciliary visit by the midwife. Design: Interviews were analysed using content analysis. Settings and participants: The nine participants were recruited from the Maternity Department at a University Hospital in Swe

Benign paroxysmal positional vertigo (BPPV) originating from the posterior semicircular canal (pSCC) is a common vestibular disorder that is easy to diagnose and usually easy to treat. The majority of patients with BPPV have no known inner ear disease; they have "primary" or "idiopathic" BPPV. However, a minority does have objective evidence of an inner ear disease on the same side as the BPPV and

Femtosecond laser pulse control of exciton dynamics in a biological chromophore complex is studied theoretically. The computations use the optimal control theory specified to open quantum systems and formulated in the framework of the rotating wave approximation. Based on the laser pulse induced formation of an excitonic wave packet the possibility to localize excitation energy at a certain chromo

Measurements of neutral pion (pi(0)) production at midrapidity in root s(NN)=200 GeV Au+Au collisions as a function of transverse momentum, p(T), collision centrality, and angle with respect to reaction plane are presented. The data represent the final pi(0) results from the PHENIX experiment for the first RHIC Au+Au run at design center-of-mass energy. They include additional data obtained using

We used a four-point resistivity method to detect wood decay in living trees. A low-frequency alternating current was applied to the stem and the induced voltage measured between two points along the stem. The effective resistivity of the stem was estimated based on stem cross-sectional area. A comparison within a group of trees showed that trees with butt rot had an effective resistivity that was

Popular Abstract in Swedish Cytostatika är en grupp läkemedel som är vanligt förekommande inom sjukvården. Cytostatika används framför allt vid behandling av olika cancersjukdomar, men kan också användas för att behandla andra sjukdomar t. ex. reumatiska sjukdomar. Dessa läkemedel kan vara mycket giftiga, cancerframkallande och fosterskadande. Cyklofosfamid (CP) och ifosfamid (IF) är två vanligt aAntineoplastic drugs are commonly used in the medical treatment of cancer and some other diseases. Workplaces e.g. hospital pharmacies and wards where antineoplastic drugs are used are contaminated with these drugs and health care workers are therefore at risk of getting occupationally exposed. Many antineoplastic drugs are classified as carcinogenic and teratogenic to humans. Cyclophosphamide (CP

Western civilization has no particular good track record of saving cultural heritage from destruction, but in recent centuries it has surrounded itself with a rather firm ideology of conservation and preservation. This paper is meant as a caution against a fundamentalist ideology of heritage-preservationism. I am discussing some inherent contradictions of how heritage is treated in the modern worl

Due to acid rain and nitrogen deposition, there is growing concern that other mineral nutrients, primarily potassium and phosphorus, might limit forest production in boreal forests. Ectomycorrhizal (EcM) fungi are important for the acquisition of potassium and phosphorus by trees. In a field investigation, the effects of poor potassium and phosphorus status of forest trees on the production of EcM
