BACKGROUND: Hodgkin lymphoma (HL) is a largely curable disease and its mortality had steadily declined in western Europe since the late 1960s. Only modest declines were, however, observed in central/eastern Europe. MATERIALS AND METHODS: We updated trends in mortality from HL in various European areas up to 2004 and analyzed patterns in incidence for selected European countries providing national data. RESULTS: In most western European countries, HL mortality continued to steadily decline up to the mid 2000s. More recent reductions were also observed in eastern European countries. Overall, mortality from HL declined from 1.17/100,000 (age-standardized, world population) in 1980-1989 to 1.42/100,000 in 2000-2004 in men from the 15 member states of the European Union (EU) from western and northern Europe. In the EU 10 accession countries of central and eastern Europe, male mortality from HL was 1.42/100,000 in 1980-1984, 1.32 in 1990-1994, and declined to 0.76 in 2000-2004. Similar trends were observed in women. No consistent patterns were found for HL incidence. CONCLUSIONS: The present work confirms the persistent declines in HL mortality in western European countries, and shows favorable patterns over more recent calendar years in central/eastern ones, where rates, however, are still at levels observed in western Europe in the early 1990s.

Background: In order to provide a cost-effective tool to analyse pharmacogenetic markers in malaria treatment, DNA microarray technology was compared with sequencing of polymerase chain reaction (PCR) fragments to detect single nucleotide polymorphisms (SNPs) in a larger number of samples. Methods: The microarray was developed to affordably generate SNP data of genes encoding the human cytochrome P450 enzyme family (CYP) and N-acetyltransferase-2 (NAT2) involved in antimalarial drug metabolisms and with known polymorphisms, i.e. CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4, CYP3A5, and NAT2. Results: For some SNPs, i.e. CYP2A6*2, CYP2B6*5, CYP2C8*3, CYP2C9*3/*5, CYP2C19*3, CYP2D6*4 and NAT2*6/*7/*14, agreement between both techniques ranged from substantial to almost perfect (kappa index between 0.61 and 1.00), whilst for other SNPs a large variability from slight to substantial agreement (kappa index between 0.39 and 1.00) was found, e. g. CYP2D6*17 (2850C>T), CYP3A4*1B and CYP3A5*3. Conclusion: The major limit of the microarray technology for this purpose was lack of robustness and with a large number of missing data or with incorrect specificity.

Scrapie is a transmissible spongiform encephalopathy with a wide PrPres dissemination in many non-neural tissues and with high levels of transmissibility within susceptible populations. Mechanisms of transmission are incompletely understood. It is generally assumed that it is horizontally transmitted by direct contact between animals or indirectly through the environment, where scrapie can remain infectious for years. In contrast, in utero vertical transmission has never been demonstrated and has rarely been studied. Recently, the use of the protein misfolding cyclic amplification technique (PMCA) has allowed prion detection in various tissues and excretions in which PrPres levels have been undetectable by traditional assays. The main goal of this study was to detect PrPres in fetal tissues and the amniotic fluid from natural scrapie infected ewes using the PMCA technique. Six fetuses from three infected pregnant ewes in an advanced clinical stage of the disease were included in the study. From each fetus, amniotic fluid, brain, spleen, ileo-cecal valve and retropharyngeal lymph node samples were collected and analyzed using Western blotting and PMCA. Although all samples were negative using Western blotting, PrPres was detected after in vitro amplification. Our results represent the first time the biochemical detection of prions in fetal tissues, suggesting that the in utero transmission of scrapie in natural infected sheep might be possible.

Compared to natural selection, domestication implies a dramatic change in traits linked to fitness. A number of traits conferring fitness in the wild might be detrimental under domestication, and domesticated species typically differ from their ancestors in a set of traits known as the domestication syndrome. Specifically, trade-offs between growth and reproduction are well established across the tree of life. According to allocation theory, selection for growth rate is expected to indirectly alter life-history reproductive traits, diverting resources from reproduction to growth. Here we tested this hypothesis by examining the genetic change and correlated responses of reproductive traits as a result of selection for timber yield in the tree Pinus pinaster. Phenotypic selection was carried out in a natural population, and progenies from selected trees were compared with those of control trees in a common garden experiment. According to expectations, we detected a genetic change in important life-history traits due to selection. Specifically, threshold sizes for reproduction were much higher and reproductive investment relative to size significantly lower in the selected progenies just after a single artificial selection event. Our study helps to define the domestication syndrome in exploited forest trees and shows that changes affecting developmental pathways are relevant in domestication processes of long-lived plants.

[spa]Identificar las dificultades halladas en el proceso de aprendizaje con la especial relación entre el esfuerzo y el logro experimentada por los estudiantes implica afrontar uno de los problemas fundamentales del aprendizaje. El presente artículo pretende abordar los aprendizajes vinculados a las competencias transversales de la búsqueda y selección de información desde el examen de la percepción de los estudiantes universitarios de arte en la realización de una carpeta de aprendizaje adaptada a la titulación y al perfil del estudiante. A partir de un enfoque cuantitativo, y mediante un estudio descriptivo transversal, se analizará la relación existente entre el esfuerzo realizado, los resultados de aprendizaje declarados y la relación entre ambas cuestiones -lo que a la postre define las dificultades- que manifiestan los estudiantes. [eng]This article aims to address the learning skills associated with the competence of searching and selecting information from the examination of the perceptions of art college students in the drawing up of a learning portfolio tailored to the degree and student profile. From a quantitative approach, and through a cross-sectional descriptive study, we will analyze the relationship between effort, stated learning outcomes and the relationship between these two issues what ultimately defines the difficulties which declare the students.
