Background: The aim was to study the incidence, time course and prognosis of patients who developed axillary recurrence after breast-conserving surgery, and to evaluate possible risk factors for axillary recurrence and prognostic factors after axillary recurrence. Methods: In a population-based cohort of 6613 women with invasive breast cancer who had breast-conserving surgery between 1981 and 1990
Infections are the most frequent complications associated with the use of central venous lines (CVLs) in children with haemophilia. Several retrospective studies that include data from a substantial number of patients have reported approximately 0.2-0.3 infections per 1000 catheter-days (mainly Port-A-Cath). Some studies have shown a much higher frequency of infections, 1-2/1000 catheter-days. The
This paper presents results from an interview investigation with teachers in Swedish nurse education especially interested in internationalising the education. The aim has been to study teachers' understandings and experiences of internationalisation against the backdrop of the strong concern for internationalisation expressed in policy documents. The results are seen in the context of globalisati
We have studied the effect of axial ligation of chlorophyll and bacteriochlorophyll using density functional calculations. Eleven different axial ligands have been considered, including models of histidine, aspartate/glutamate, asparagine/glutamine, serine, tyrosine, methionine, water, the protein backbone, and phosphate. The native chlorophylls, as well as their cation and anion radical states an
When 7-oxodesacetamidothiocolchicine ( 1) was treated with various peroxides in order to afford a Baeyer-Villiger rearrangement, a complex mixture of products was formed, which included the sulfoxide, ( 2) and sulfone, ( 3). When peracetic acid was used two additional products were formed; a C-ring lactone ( 4) and a ring-contracted allocolchicine derivative ( 5). The sulfoxide ( 2) was semi-prepa
This paper discusses recent advances that have been made in the field of psychometrics, specifically, the application of Rasch analysis to the instrument development process. It emphasizes the importance of assessing the fundamental scaling properties of an instrument prior to consideration of traditional psychometric indicators. The paper introduces Rasch analysis and shows how it has been applie
The purpose of this study is to provide information from two prospective long-term follow-ups for severe road traffic injuries in Sweden. The long-term consequences, in terms of loss of health and costs of care, are presented for severe injuries in Sweden in the early 1990s and are compared with information on injury severity and health care utilisation 25 years ago. The follow-up in the 1990s sho
The biochemistry and molecular genetics underlying the related carbohydrate blood group antigens P, P(k), and LKE in the GLOB collection and P1 in the P blood group system are complex and not fully understood. Individuals with the rare but clinically important erythrocyte phenotypes P(1)k and P(2)k lack the capability to synthesize P antigen identified as globoside, the cellular receptor for Parvo
Copper(I)-catalyzed addition of alkynes to methyl 3-azido-3-deoxy-1-thio-β-d-galactopyranoside afforded stable and structurally simple 3-deoxy-3-(1H-1,2,3-triazol-1-yl)-1-thio-galactosides carrying a panel of substituents at the triazole C4 in high yields. The 3-(1H-[1,2,3]-triazol-1-yl)-1-thio-galactoside collection synthesized contained inhibitors of the tumor- and inflammation-related galectin-
The effect of pretreating cell suspensions of embryonic rat ventral mesencephala (VM) with antioxidant combinations on the survival of dopaminergic (DA) neurons was studied in vitro and following transplantation into the unilateral 6-hydroxydopamine (6-OHDA)-lesioned rat model of Parkinson's disease. The in vitro experiments examined the effects of two thiol antioxidants, N-acetyl-L-cysteine (NAC)
We have developed a new Internet service, which provides mobile access to bioinformatics databases and software tools. The BioWAP service facilitates access to basic bioinformatics databases and analysis tools from everywhere without a PC or a laptop computer. Both open source bioinformatics. program suites and Internet services, which are not designed for mobile Internet access, were utilized in
ABSTRACT: INTRODUCTION: Ventilator-associated pneumonia (VAP) is usually caused by aspiration of pathogenic bacteria from the oropharynx. Oral decontamination with antiseptics, such as chlorhexidine (CHX) or antibiotics, has been used as prophylaxis against this complication. We hypothesised that the probiotic bacteria Lactobacillus plantarum 299 (Lp299) would be as efficient as CHX in reducing th
The study explored the counterfactual thinking that women with chronic and widespread pain showed in response to what they themselves considered to be particularly stressful situations. Counterfactual thinking in 125 women sick-listed due to chronic and widespread pain was investigated in terms of structure, function and control focus. The women were asked, for each of three types of problems that
BB-Diabetes Prone (BB-DP) rats, a model for endocrine autoimmune diseases, are severely lymphopenic, especially lacking ART2+ regulatory T cells. BB-Diabetes Resistant (DR) rats are not lymphopenic and do not develop autoimmunity. BB-DP and BB-DR rats only differ at the lymphopenia (lyp) gene (iddm2) on chromosome 4. Since BB-DP rats also show aberrancies in the differentiation of dendritic cells
We have shown previously that protein kinase C (PKC) epsilon can induce neurite outgrowth independently of its catalytic activity via a region encompassing its C1 domains. In this study we aimed at identifying specific amino acids in this region crucial for induction of neurite outgrowth. Deletion studies demonstrated that only 4 amino acids N-terminal and 20 residues C-terminal of the C1 domains
The polarizabilities of polyampholytes have been calculated in Monte Carlo simulations. For chains with random charge topologies, the polarizability increases with the chain length and the chain flexibility. For block copolymers, the polarizability initially increases with the block size to a maximum and then decreases. The polarizability is used to characterize the interaction between polyampholy
The aerosol in the Amazon basin is dominated throughout the year by organic matter, for the most part soluble in water. In this modeling study, we show how the knowledge of water-soluble organic compounds (WSOC) and the associated physical and chemical properties (e.g. solubility, surface tension, dissociation into ions) affect the hygroscopic growth and activation of the aerosol in this area. The
