Isolation and characterisation of microsatellite loci for two species of Spinturnicid wing mites (Spinturnix myoti and Spinturnix bechsteini)

To investigate the potential for host-parasite coadaptation between bats and their wing mites, we developed microsatellite loci for two species of Spinturnix mites. For Spinturnix myoti, parasite of Myotis myotis, we were able to develop nine polymorphic loci and screened them in 100 mites from five bat colonies. For S. bechsteini, parasite of M. bechsteinii, we developed five polymorphic loci, which were also screened in 100 mites from five bat colonies. In both species, all markers were highly polymorphic (22-46 and 6-23 alleles per locus respectively). The majority of markers for both species exhibited departure from Hardy-Weinberg proportions (8 of 9 and 3 of 5, respectively). One marker pair in S. myoti showed evidence for linkage disequilibrium. As the observed departures from Hardy-Weinberg proportions are most likely a consequence of the biology of the mites, the described microsatellite loci should be useful in studying population genetics and host-parasite dynamics of Spinturnix myoti and Spinturnix bechsteini in relation to their bat hosts.

Long-term complete responses after 131I-tositumomab therapy for relapsed or refractory indolent non-Hodgkin's lymphoma.

We present the long-term results of 18 chemotherapy relapsed indolent (N = 12) or transformed (N = 6) NHL patients of a phase II anti-CD20 (131)I-tositumomab (Bexxar) therapy study. The biphasic therapy included two injections of 450 mg unlabelled antibody combined with (131)I-tositumomab once as dosimetric and once as therapeutic activity delivering 75 or 65 cGy whole-body radiation dose to patients with normal or reduced platelet counts, respectively. Two patients were not treated due to disease progression during dosimetry. The overall response rate was 81% in the 16 patients treated, including 50% CR/CRu and 31% PR. Median progression free survival of the 16 patients was 22.5 months. Median overall survival has not been reached after a median observation of 48 months. Median PFS of complete responders (CR/CRu) has not been reached and will be greater than 51 months. Short-term side effects were mainly haematological and transient. Among the relevant long-term side effects, one patient previously treated with CHOP chemotherapy died from secondary myelodysplasia. Four patients developed HAMA. In conclusion, (131)I-tositumomab RIT demonstrated durable responses especially in those patients who achieved a complete response. Six of eight CR/CRu are ongoing after 46-70 months.

Atenção pré-natal por enfermeiros na Zona Leste da cidade de São Paulo - Brasil

Com o objetivo de analisar o exercício das competências dos enfermeiros para a atenção pré-natal por meio da identificação das atividades que desempenham e sua frequência, bem como dos possíveis obstáculos que encontram, realizou-se estudo quantitativo, descritivo-exploratório, em 59 Unidades Básicas de Saúde da Zona Leste da cidade de São Paulo, de outubro de 2006 a dezembro de 2007. A amostra foi constituída de 131 enfermeiros. Os resultados mostraram que os enfermeiros não exercem as competências essenciais para a atenção qualificada ao pré-natal, devido às barreiras pessoais e institucionais com que se defrontam em seu trabalho. Conclui-se pela necessidade das estruturas públicas de saúde municipais revisarem suas políticas de modo a garantir a implementação das diretrizes do SUS no que se refere à melhoria da atenção à saúde materno-infantil, e à destinação de recursos humanos e financeiros nessa direção.

Gene finding in the chicken genome

Background: Despite the continuous production of genome sequence for a number of organisms,reliable, comprehensive, and cost effective gene prediction remains problematic. This is particularlytrue for genomes for which there is not a large collection of known gene sequences, such as therecently published chicken genome. We used the chicken sequence to test comparative andhomology-based gene-finding methods followed by experimental validation as an effective genomeannotation method.Results: We performed experimental evaluation by RT-PCR of three different computational genefinders, Ensembl, SGP2 and TWINSCAN, applied to the chicken genome. A Venn diagram wascomputed and each component of it was evaluated. The results showed that de novo comparativemethods can identify up to about 700 chicken genes with no previous evidence of expression, andcan correctly extend about 40% of homology-based predictions at the 5' end.Conclusions: De novo comparative gene prediction followed by experimental verification iseffective at enhancing the annotation of the newly sequenced genomes provided by standardhomology-based methods.

Design and evaluation of a panel os single-nucleotide polymorphisms in microRNA genomic regions for association studies in human disease

MicroRNAs (miRNA) are recognized posttranscriptional gene repressors involved in the control of almost every biological process. Allelic variants in these regions may be an important source of phenotypic diversity and contribute to disease susceptibility. We analyzed the genomic organization of 325 human miRNAs (release 7.1, miRBase) to construct a panel of 768 single-nucleotide polymorphisms (SNPs) covering approximately 1 Mb of genomic DNA, including 131 isolated miRNAs (40%) and 194 miRNAs arranged in 48 miRNA clusters, as well as their 5-kb flanking regions. Of these miRNAs, 37% were inside known protein-coding genes, which were significantly associated with biological functions regarding neurological, psychological or nutritional disorders. SNP coverage analysis revealed a lower SNP density in miRNAs compared with the average of the genome, with only 24 SNPs located in the 325 miRNAs studied. Further genotyping of 340 unrelated Spanish individuals showed that more than half of the SNPs in miRNAs were either rare or monomorphic, in agreement with the reported selective constraint on human miRNAs. A comparison of the minor allele frequencies between Spanish and HapMap population samples confirmed the applicability of this SNP panel to the study of complex disorders among the Spanish population, and revealed two miRNA regions, hsa-mir-26a-2 in the CTDSP2 gene and hsa-mir-128-1 in the R3HDM1 gene, showing geographical allelic frequency variation among the four HapMap populations, probably because of differences in natural selection. The designed miRNA SNP panel could help to identify still hidden links between miRNAs and human disease.

Doxycycline increases neurogenesis and reduces microglia in the adult hippocampus.

Adult hippocampal neurogenesis results in the continuous formation of new neurons and is a process of brain plasticity involved in learning and memory. Although inducible-reversible transgenic mouse models are increasingly being used to investigate adult neurogenesis, transgene control requires the administration of an activator, doxycycline (Dox), with unknown effects on adult neurogenesis. Here, we tested the effect of Dox administration on adult neurogenesis in vivo. We found that 4 weeks of Dox treatment at doses commonly used for gene expression control, resulted in increased neurogenesis. Furthermore, the dendrites of new neurons displayed increased spine density. Concomitantly, Iba1-expressing microglia was reduced by Dox treatment. These results indicate that Dox treatment may interfere with parameters of relevance for the use of inducible transgenic mice in studies of adult neurogenesis or brain inflammation.

Individualisation du croire et recomposition de la religion

Dans cet article, j'aimerais poursuivre l'interprétation de données sur le croire, plus précisément sur celles relatives aux croyances. Ces données ont été collectées tout au long de la recherche dont nous venons de publier les résultats dans un ouvrage intitulé précisément «Croire en Suisse(s)». En prenant quelque distance par rapport à notre première interprétation des réponses suisses relatives au domaine des croyances, des questions épis-témologiques nouvelles sont apparues, inspirées à la fois par une deuxième lecture moins à chaud et par les remarques de quelques collègues. Je vais donc tenter de formuler ces questions puis de les appliquer aux données mentionnées.

Variability of radioiodine measurements in the thyroid.

Monte Carlo simulations were carried out to study the response of a thyroid monitor for measuring intake activities of (125)I and (131)I. The aim of the study was 3-fold: to cross-validate the Monte Carlo simulation programs, to study the response of the detector using different phantoms and to study the effects of anatomical variations. Simulations were performed using the Swiss reference phantom and several voxelised phantoms. Determining the position of the thyroid is crucial for an accurate determination of radiological risks. The detector response using the Swiss reference phantom was in fairly good agreement with the response obtained using adult voxelised phantoms for (131)I, but should be revised for a better calibration for (125)I and for any measurements taken on paediatric patients.

Actitud ante el consumo y no consumo de alcohol en estudiantes de preparatoria – México

El objetivo del estudio fue identificar diferencias de actitud entre estudiantes de la educación secundaria consumidores y no de alcohol a través de la Teoría de la Conducta Planeada. Estudio descriptivo transversal con abordaje cuantitativo, con una muestra de 131 adolescentes. Se verifi có que 74% ya habían consumido alcohol y 18.3% tienen consumo dañino. Se constató que las creencias conductuales hacia el consumo eran más altas en los consumidores de alcohol (X=29.32, Mdn=27.50) que en los no consumidores, así con la evaluación de las creencias en sentido positivo son más altas en los consumidores de alcohol (X=17.72, Mdn=9.52) que en los no consumidores, haciéndose necesaria la implementación de programas preventivos que fortalezcan las creencias de los adolescentes, así como estimular las estrategias vinculadas con el fortalecimiento de factores protectores y estilos de vida saludables.
