    Fas ligand (FasL) is expressed on some cancers and may play a role in the immune evasion of the tumour. We used immuno-histochemistry to study the expression of Fas and FasL in tissue samples from breast cancer patients, as well as normal breast tissue. Our results show that Fas and FasL are co-expressed both in normal tissue and in breast tumours. Fas and FasL mRNA were expressed in fresh normal and malignant breast tissue, as well as cultured breast epithelium and breast cancer cell lines. Flow cytometry analysis of live cells failed to detect FasL on the surface of normal or malignant breast cells; however, both stained positive for FasL after permeabilization. Fas was detected on the surface of normal breast cells and T47D and MCF-10A cell lines but only intracellularly in other breast cell lines tested. Neither normal breast epithelium nor breast cell lines induced Fas-dependent apoptosis in Jurkat cells. Finally, 20 tumour samples were stained for apoptosis. Few apoptotic cells were detected and there was no increase in apoptotic cells on the borders between tumour cells and lymphocytes. We conclude that FasL is expressed intracellularly in both normal and malignant breast epithelium and unlikely to be important for the immune evasion of breast tumours. © 2000 Cancer Research Campaign http://www.bjcancer.co

    A critique of neo-mercantilist analyses of Icelandic political economy and crisis

    Get PDF
    Iceland’s journey from rags to riches in the 20th century is related, in the dominant discourse, to its gaining independence in 1944. This discourse played a significant role in both the legitimation of the finance-dominated growth model in the 1990s and 2000s and in the latter’s defence as it came under scrutiny before its collapse in October 2008. It is therefore ironic – or perhaps, in some sense, logical – to find dominant analyses of the crisis arising from the neo-mercantilist tradition. Drawing on Marxist critiques of neo-mercantilism, we challenge these interventions and thus seek to redress the neglect of social struggle in the dominant discourse

    A hospitalização é uma experiência complexa, sendo agravada no caso de necessidade de intervenção cirúrgica, principalmente quando o paciente é criança. Quando a cirurgia é suspensa, paciente e seus familiares podem apresentar sentimentos de insegurança, angústia e ansiedade. Este estudo teve como objetivo identificar e descrever a percepção de quinze mães e/ou responsáveis por crianças de 0 a 18 anos, internadas em um hospital, após receberem a notícia de que a cirurgia de seu filho foi suspensa. É um estudo descritivo, qualitativo, que utilizou o referencial teórico da Comunicação Interpessoal e o metodológico da Análise de Conteúdo. Os resultados evidenciaram que as suspensões de cirurgias pediátricas são fatos presentes na instituição, que trazem repercussões ao paciente e familiares, e à organização institucional; que a comunicação entre profissionais da saúde, pacientes e familiares é inadequada; que a atuação do enfermeiro na notícia da suspensão da cirurgia precisa ser efetiva.La hospitalización es una experiencia compleja, agravada en el caso de ser necesaria una intervención quirúrgica, en particular cuando el enfermo es un niño.

Los resultados evidenciaron que las suspensiones de cirugías pediátricas son hechos presentes en la institución, que traen repercusiones al enfermo y familiares y en la propia organización institucional, que la comunicación entre profesionales de la salud, enfermos y familiares es inadecuada y que la actuación del enfermero en la noticia de la suspensión de la cirugía debe ser necesariamente efectiva.Hospitalization is a complex experience; this can be made worse if surgical intervention is required, especially when the patient is a child. When surgery is suspended, patient and family can experience feelings of insecurity, distress, and anxiety. The objective of this study was to identify and describe the perceptions of fifteen mothers or guardians of children between 0 and 18 years old admitted in a teaching hospital, after receiving news that surgery for their child was suspended. This was a descriptive qualitative study which used Interpersonal Communication as theoretical reference and Analysis of Content as the methodology. Results showed that suspension of pediatric surgery in our institution causes repercussions to patients, their families, and institution organisation; that communication between health team professionals, patients and families is inadequate; and that the nurses' participation in informing surgery suspension must be effective

    Composition analysis and minimal treatments to solubilize polysaccharides from the brown seaweed Laminaria digitata for microbial growth of thermophiles

    Publisher's version (útgefin grein)Brown macroalgae (Phaeophyta) hold high potential as feedstock for biorefineries due to high biomass productivity and carbohydrate content. They are, however, a challenging, unconventional feedstock for microbial refining and several processing problems need to be solved to make them a viable option. Pre-treatment is necessary to enhance accessibility and solubility of the biomass components but should be minimal and mild to assure sustainable and cost-effective processing. Here, two routes to pre-treatLaminaria digitata to release polysaccharides were investigated: hot water pre-treatment by autoclaving (121 °C, 20 min or 60 min) and a two-step extraction with mild acid (0.1 M HCl) followed by alkaline treatment. Hot water pre-treatment resulted in partial extraction of a mixture of polysaccharides consisting of alginate, fucoidan and laminarin. After mild acid pre-treatment, alginate was found in the remaining insoluble residues and was extracted in a second step via alkaline treatment using Na2CO3 (0.15 M) at 80 °C and CaCl2 (10%) for the precipitation. In addition to carbohydrates, a fraction of other components such as proteins, phenolic compounds, minerals and trace elements was detected in the extracts. Cultivation of the thermophilic bacterial strains Rhodothermus marinus DSM 16675 and Bacillus methanolicus MGA3 (ATCC 53907) in media supplemented with the respective extracts resulted in growth of both strains, indicating that they were able to utilize the available carbon source for growth. R. marinus displayed the highest cell density in the medium containing the extract from acid pre-treatment, whereas B. methanolicus growth was highest with the extract from hot water pre-treatment.Open access funding provided by Lund University.

    <p>Abstract</p> <p>Background</p> <p>School related factors that may contribute to children's subjective health have not been extensively studied. We assessed whether factors assumed to promote health and factors assumed to have adverse effects were associated with self-reported internalizing or somatic symptoms.</p> <p>Methods</p> <p>In a cross-sectional study, 230 boys and 189 girls in grades 1-10 from five schools responded to the same set of questions. Proportional odds logistic regression was used to assess associations of school related factors with the prevalence of sadness, anxiety, stomach ache, and headache.</p> <p>Results</p> <p>In multivariable analyses, perceived loneliness showed strong and positive associations with sadness (odds ratio, 1.94, 95% CI 1.42 to 2.64), anxiety (odds ratio, 1.78, 95% CI 1.31 to 2.42), and headache (odds ratio, 1.47, 95% CI 1.10 to 1.96), with consistently stronger associations for girls than boys. Among assumed health promoting factors, receiving necessary help from teachers was associated with lower prevalence of stomach ache in girls (odds ratio, 0.51, 95% CI 0.30 to 0.87).</p> <p>Conclusions</p> <p>These findings suggest that perceived loneliness may be strongly related to both internalizing and somatic symptoms among school children, and for girls, the associations of loneliness appear to be particularly strong.</p

    Recognising Victimhood: Lessons from the International Criminal Court and Mass Claim Programmes for the Compensation Procedure Parallel to the Trial of International Crimes in the Netherlands

    Get PDF
    In the Netherlands, the Dutch criminal court in The Hague (hereinafter: ‘Netherlands International Crimes Court’ or ‘NIC court’) is assigned to try international crimes, and to provide compensation to victims of such crimes. Whereas it has specific criminal laws at its disposal to try international crimes, it applies ‘regular’ Dutch civil law to assess claims for compensation. Yet compensation for international crimes entails challenges that are quite different from domestic crimes: international crimes are normally committed against a large number of victims, and frequently result in bodily harm. This article argues that the NIC court will most likely rule a large number of claims for compensation inadmissible, as a consequence of which victims cannot benefit from the advantages inherent in the award of compensation within the criminal process. It then explores the adjudicative and reparatory standards that the International Criminal Court and mass claim programmes have applied to simplify both the adjudication of a large number of claims, and the calculation of a large number of instances of bodily damage. It is submitted that adoption by the NIC court of international reparatory standards could facilitate the assessment of a large number of civil claims within the criminal process, without prejudice to the legitimate interests of the defendant for an adequate procedure. However, these standards require the NIC court to strike a new balance between tailor-made compensation and symbolic compensation, and thereby between corrective justice and restorative justice
