Constrained by national tests and the mathematics curriculum, teachers have problems finding time for exploratory and hands-on mathematical activities, especially so in classes with a reduced pace of progression, for example because of a large proportion of second-language learners. Could the leisure-time center, where time is not earmarked, provide such opportunities? The conclusion of this thesi

In this paper, we discuss common features found in what we term trade languages. Some languages change their grammatical shape dramatically after intense contacts with other languages. Pidgin and creole languages are often discussed in terms of contacts, but trade languages are slightly different from them on the following points: trade languages are normally formed with mutually intelligible lang

Immunotherapy of malignant primary brain tumors holds the potential to improve the dismal prognosis after current clinical therapy. Although immunotherapy of experimental gliomas has been demonstrated to have the capacity to cure intracerebral tumors no convincing effects of immunotherapy have been shown in clinical trials. One reason for this could be that some of the models used do not display f

Background: In diagnosing acute pulmonary embolism (PE) in azotemic patients, scintigraphy and magnetic resonance imaging are frequently inconclusive or not available in many hospitals. Computed tomography is readily available, but relatively high doses (30-50 g I) of potentially nephrotoxic iodine contrast media (CM) are used. Purpose: To report on the diagnostic quality and possible contrast-ind

Dietary carbohydrates have been implicated in relation to prostate cancer.

Spontaneous movements are a ubiquitous phenomenon during development. Recently, we demonstrated that these movements play a key role in the functional adaptation of spinal reflex circuits. Here, we analyse the role of afferent input in the generation of spontaneous movements and characterize the occurrence of different types of spontaneous movements and their relation to the functional adaptation

GADS is a member of a family of SH2 and SH3 domain-containing adaptors that functions in tyrosine kinase-mediated signaling cascades. Its expression is largely restricted to hematopoietic tissues and cell lines. Therefore, GADS is mainly involved in leukocyte-specific protein tyrosine kinase signaling. GADS is known to interact with tyrosine-phosphorylated SHC, BCR-ABL and KIT. The SH2 domain of G

We studied the effects of the national Perinatal Patient Safety Program in Sweden, addressing local improvement measures, changes in the proportion of low Apgar Score and the number of settled injury claims due to asphyxia.

BACKGROUND: Lead time, the estimated time by which screening advances the date of diagnosis, is used to calculate the risk of overdiagnosis. We sought to describe empirically the distribution of lead times between an elevated prostate-specific antigen (PSA) and subsequent prostate cancer diagnosis. METHODS: We linked the Swedish cancer registry to two independent cohorts: 60-year-olds sampled in 1

The aim of the study was to assess the impact of cardiopulmonary bypass surgery on corrected QT (QTc) and QT dispersion (QTd) intervals. The possible role of inflammation on these variables was investigated.
