Health needs of the Roma population in the Czech and Slovak Republics.

In the growing literature on the human rights of Roma people in Central Europe, their relatively poor health status is often mentioned. However, little concrete information exists about the contemporary health status of the Roma in this region. We sought information on the health of the Roma in two of countries with significant Roma minorities, the Czech and Slovak Republics, by means of systematic searches for literature on the health of Roma people published in Czech or Slovak or by authors from the two countries. Published research on health of the Roma population is sparse. The topics that have received attention suggest a focus on concepts of contagion or social Darwinism, indicating a greater concern with the health needs of the majority populations with which they live. What limited evidence exists indicates that the health needs of the Roma population are considerable. With very few exceptions, the health status of Roma is worse than that of non-Roma population in both countries. The burden of communicable disease among Roma is high and diseases associated with poor hygiene seem to be particularly important. Evidence on health care suggests poor communication between Roma and health workers and low uptake of preventative care. The health needs of Roma lack visibility, not only because of the absence of research but also the absence of advocacy on their behalf. Since 1989, Czech and Slovak researchers have largely turned away from health research on particular ethnic groups. This probably reflects a growing sensitivity about stigmatising Roma, but it also makes it difficult to know how their circumstances might be improved. There is a need for further research into the health of Roma people with particular emphasis on non-communicable disease and for interventions that would improve their health

La enhances IRES-mediated translation of laminin B1 during malignant epithelial to mesenchymal transition

The majority of transcripts that harbor an internal ribosome entry site (IRES) are involved in cancer development via corresponding proteins. A crucial event in tumor progression referred to as epithelial to mesenchymal transition (EMT) allows carcinoma cells to acquire invasive properties. The translational activation of the extracellular matrix component laminin B1 (LamB1) during EMT has been recently reported suggesting an IRES-mediated mechanism. In this study, the IRES activity of LamB1 was determined by independent bicistronic reporter assays. Strong evidences exclude an impact of cryptic promoter or splice sites on IRES-driven translation of LamB1. Furthermore, no other LamB1 mRNA species arising from alternative transcription start sites or polyadenylation signals were detected that account for its translational control. Mapping of the LamB1 5′-untranslated region (UTR) revealed the minimal LamB1 IRES motif between −293 and −1 upstream of the start codon. Notably, RNA affinity purification showed that the La protein interacts with the LamB1 IRES. This interaction and its regulation during EMT were confirmed by ribonucleoprotein immunoprecipitation. In addition, La was able to positively modulate LamB1 IRES translation. In summary, these data indicate that the LamB1 IRES is activated by binding to La which leads to translational upregulation during hepatocellular EMT

Changes in the fish fauna and fisheries in the Slovak section of the Danube River: a review

The fish diversity of the Slovak segment of the Danube (representing the transitional zone from the rhithron to the potamon) was under the control of the inland delta which existed in this region until 1992. Seventy-six species were recorded in the studied river section: 61 species were native, 11 were exotic, 5 or 7 were invaders from the lower sections of the Danube, 3 species (and one form) became extinct, and 7 species were not detected during the past 20 years. The increasing pollution until 1985 decreased the fish species richness, but the improvement of water quality thereafter rose their number. However, the construction of the Gabcíkovo River Barrage System put in operation in October 1992 started to change substantially fish species richness and quantity, and fish catch. The formerly functional inland delta controlled by the pulsating discharge disappeared, and was changed to an artificial system of isolated or only marginally connected habitats. The upstream fish migration was stopped by the Gabcíkovo dam and weirs in Cunovo. Therefore, the fish fauna of the side arms lost contact with fish of the main channel and of the bypass canal downstream. The loss of spawning habitats had fatal effects, especially for the wild carp and the pike, which number rapidly decreased. In general, the number of fish species, their density, and fish catch decreased significantly. To improve the situation, it is proposed: 1) to restore the bilateral connection between the main channel and the side arms, 2) to ensure fish migration between the main channel and the side arms, and 3) to simulate the original flooding of the floodplain

Age and growth of two newly established invasive populations of Tilapiamariae in northern Australia

Sagittal otoliths were used to age the samples of Tilapia mariae collected from a coastal river and an impoundment. Validation of sagittae checks was achieved using both quantitative marginal increment analysis and by tetracycline marking of the otoliths of fish kept in tanks and in a farm dam. The annulus pattern on the otoliths was generally clear and their formation appeared to be temperature related and largely completed in the Austral spring around September and October. Male T. mariae grow faster and larger than females and the maximum ages of fish from the coastal river and impoundment was 9+ and 4+ years, respectively. Past fish surveys and the absence of older age classes in the impoundment population would suggest that this population was only very recently established
