The study which was conducted from January 2003 to December 2004 was to yield a specific knowledge about the technical and institutional problems, challenges and opportunities in planning for sustainable urban transportation. Before reaching this stage, it was necessary to get a clear picture the problem, and this showed that the performance of public transportation in Dar-es-Salaam in terms of so
Nineteen pre-school children with language impairment participated in a computerized naming task. The naming procedure involved two conditions, one unprimed where the child had to name a colour picture appearing on the screen as fast as possible and one primed where the picture was preceded by an uncompleted sentence. Response times were significantly shorter in the primed condition compared to th
Originally cloned from hematopoietic stem cell (HSC) populations and its ligand being extensively used to promote ex vivo HSC expansion, the FMS-like tyrosine kinase 3 (FLT3; also called FLK2) receptor and its ligand (FL) were expected to emerge as an important physiologic regulator of HSC maintenance and expansion. However, the role of FLT3 receptor and ligand in HSC regulation remains unclear an
Tree nuts, peanuts and seeds are nutrient dense foods whose intake has been shown to be associated with reduced risk of some chronic diseases. They are regularly consumed in European diets either as whole, in spreads or from hidden sources (e.g. commercial products). However, little is known about their intake profiles or differences in consumption between European countries or geographic regions.
This longitudinal study (1994-1996) used the Gordon Personality Inventory to measure nursing students' self-image (Gordon A), self-values (Gordon B) and interpersonal values (Gordon C). It was performed with students from three colleges of health in the south of Sweden: Jonkoping (n = 54), Vaxjo (n = 24) and Kristianstad (n = 38). The null hypothesis of the study was that the new academic three-ye
We review and discuss the importance of correlational selection (selection for optimal character combinations) in natural populations. If two or more traits subject to multivariate selection are heritable, correlational selection builds favourable genetic correlations through the formation of linkage disequilibrium at underlying loci governing the traits. However, linkage disequilibria built up by
Sensory nerve desensitization by capsaicin has been shown to improve the diabetic condition in Zucker Diabetic Fatty rats. However, administration of capsaicin to adult rats is associated with an increased mortality. Therefore, in this experiment, we examined the influence of resiniferatoxin, a tolerable analogue of capsaicin suitable for in vivo use, on the diabetic condition of Zucker Diabetic F
Background: Lack of professional development opportunities among nursing staff is a major concern in elderly care and has been associated with work dissatisfaction and staff turnover. There is a lack of prospective, controlled studies evaluating the effects of educational interventions on nursing competence and work satisfaction. Objectives: The aim of this study was to evaluate the possible effec
A total of 3,016 malignant solid tumors (kidney, colorectal, breast, head and neck, ovarian, and lung carcinomas, neuroglial tumors, malignant melanoma, and testicular germ cell tumors) were selected for statistical analyses regarding karyotypic evolution. Genomic imbalances, i.e., net gains and losses, present in more than 5% of each tumor type were identified. Individual tumors were then classif
Maintaining optimal visual performance is a difficult task in the photodynamic coastal and estuarine waters in which western North Atlantic sciaenid fishes support substantial commercial and recreational fisheries. Unavoidable tradeoffs exist between visual sensitivity and resolution, yet sciaenid visual systems have not been characterized despite strong species-specific ecomorphological and micro
Some fungal species have been listed as a problem causing fungi in indoor air and most of this group are known to produce mycotoxins. So far, mycotoxins have been found in building materials and in samples representing settled indoor air dust, as well in air samples from industrial or agricultural environments. The present paper presents the results of a mycological study and mycotoxin analyses of
This paper reports results of a reexamination of some poorly understood peculiarities of laccases, an enzyme family which has been extensively studied in our laboratories as well as by others for some years. The issue that is reconsidered here is the previously proposed existence of ''active" and "resting" forms of laccases. The presence of fungal laccases with partly reduced active sites is demon
Background: Neuroblastoma tumor cells are assumed to originate from primitive neuroblasts giving rise to the sympathetic nervous system. Because these precursor cells are not detectable in postnatal life, their transcription profile has remained inaccessible for comparative data mining strategies in neuroblastoma. This study provides the first genome-wide mRNA expression profile of these human fet
The purpose of this multicenter study was to determine the accuracy and clinical value of a dedicated breast biopsy system which allows for MR-guided vacuum biopsy (VB) of contrast-enhancing lesions. In five European centers, MR-guided 11-gauge VB was performed on 341 lesions. In 7 cases VB was unsuccessful. This was immediately realized on postinterventional images or direct follow-up combined wi
