Background: Existing studies of solid cancers in rheumatoid arthritis ( RA) reflect cancer morbidity up until the early 1990s in prevalent cohorts admitted to hospital during the 1980s. Objective: To depict the cancer pattern of contemporary patients with RA, from updated risk data from prevalent and incident RA populations. To understand the risk of solid cancer after tumour necrosis factor (TNF)

16 patients with chronic hepatitis C virus (HCV) infection were treated with a combination of interferon-alpha and ribavirin for 24 weeks in an open study. One patient declined further treatment due to depression after week 16 and did not complete further follow-up. A moderate decline was observed in hemoglobin and an increase in bilirubin level both reversible after discontinuing the treatment. 2

Abstract in French L'objectif de cette étude exploratoire est de voir si l'utilisation des formes interlangagières du type "je parlE" ou "je veux habite" par des apprenants suédophones adultes du français langue étrangère seraient influencées par la fréquence des formes dans l'input. L'étude est faite à partir de données de production orale (apprenants) et de données du français parlé (input).

Background: Achalasia is considered to be a primary motor disorder of the oesophagus. However, there is increasing evidence to suggest extra- oesophageal involvement in this disease. Vagal disturbances at different levels and extra- oesophageal dysmotility have been reported in several studies. The aim of this study was to examine cardiovascular reflexes in patients with achalasia further to evalu

Analys av incest- och rasblandningsmotiven i Förföljaren (The Searchers, 1956) och De oförsonliga (The Unforgiven, 1960).

Data of 1,337 consecutive hip fracture patients were registered during I year within a prospective comparative multicenter study comparing osteosynthesis techniques and rehabilitation results in Budapest, Hungary, in Sundsvall, northern Sweden, and in Lund, southern Sweden. In Budapest the mean age was 4-5 years lower than in Sweden, and more patients lived in their own home (91% versus 70% and 62

Problems in classification of main systematic groups are discussed for lichenized ascomycetes exemplified mainly with the Teloschistaceae and Parmeliaceae. Different criteria for delimiting genera and species in these two families are discussed. The lack of separating infraspecific taxa for assigning evolutionary divergence is obvious in both families. The subspecific category is rarely used in li

Falling birth rates within the European Union have given rise to a number of studies, trying to analyse and interpret why women (and men) choose not to have (many) children. One attempt in this direction is made by an ongoing EU-project, involving eight countries, including Sweden. Qualitative interviews focusing on couples' decisions to have- or not have - children have been carried out in each c

Long-term eddy covariance measurements of energy and water fluxes and associated climatic parameters were carried out above a Scots pine (Pinus sylvestris) forest in the middle taiga zone of Central Siberia. Data from June 1998 through October 2000 are presented. With the exception of winter 1998/1999, data collection over this period were more or less continuous. A distinct seasonality in surface

Alkyd-acrylic hybrids having final solids content of 75-80% were prepared by dropping alkyd resin into an acrylic dispersion. The resulting suspo emulsion structures and the alkyd droplet sizes in the hybrids were dependent on the preparation procedure as well as the interfacial tension between the two liquid phases, sigma(12), the shear rate, gamma, the latex/alkyd ratio and the viscosity ratio,

Results on diffractive photoproduction of psi(2S) mesons are presented using data collected between 1996 and 2000 with the H1 detector at the HERA ep collider. The data correspond to an integrated luminosity of 77 pb(-1). The energy dependence of the diffractive psi(2S) cross section is found to be similar to or possibly somewhat steeper than that for J/psi mesons. The dependences of the elastic a

The modeling of non-reflecting one-dimensional dispersive media is discussed. The media are temporal dispersive with a spatially varying impedance. It is shown that the effects from the variation of the impedance can be matched by the temporal dispersive effects so that the media do not reflect any field regardless of the shape of the incident transient field. The problem of finding reflectionless

The behavior of polyampholytes (PAs) in electric fields is investigated by Monte Carlo simulations. In bulk it is found that the response of the PA depends on the charge sequence. For small repeating units of positive and negative charges the response is linear, while bigger units results in a nonlinear response in both the induced dipole moment and the resulting polymer conformation. This is refl

As a part of the Europe-wide research project 'Unification of physical and clinical requirements for medical X-ray imaging'-governed by the Radiological Imaging Unification Strategies (RADIUS) Group-a major image quality trial was conducted by members of the group. The RADIUS chest trial aimed at thoroughly examining various aspects of nodule detection in digital chest radiography, such as the eff

The neurohypophyseal hormones oxytocin and vasopressin are important in the regulation of uterine contractility. These hormones, as well as prostaglandin F2α, are most forceful myometrial tissue contractors. Vasopressin is probably a causative factor in primary dysmenorrhoea, whereas oxytocin is the major uterine stimulator of labour, both at term and preterm. In a prospective study we investiga

One of the developments of today, especially in the area of environmental sustainability, is the call for multi-stakeholder, regional collaboration. Strong political and ideological support often implies that collaboration is the magic stick through which our complex problems or questions can be solved, even when and where expertise is not yet available. This paper explores the most frequent promi
