Mycetoma caused by Nocardia brasiliensis in an immunocompetent patient

Dendritic cells play a central role in the regulation of immunological reactivity. The existence of functionally specialized populations of dendritic cells in the skin is a consequence of qualitatively different attacks on our organism. slanDCs are human inflammatory dendritic cells that are characterized by the specific expression of the carbohydrate 6-sulfo LacNAc (slan). After phenotypic maturation, slanDCs are capable of producing very high amounts of proinflammatory mediators such as IL-12, TNF-, IL-1 and IL-23. Recent data describe a potential role of slanDCs in a number of different diseases like psoriasis, lupus erythematosus, and tumors, thus opening up new areas of research on their respective pathogenesis. Furthermore, a slanDC-specific targeting system has been developed as a basis for direct therapeutic manipulation. Future challenges of slanDC research include deepening our understanding of the significance of slanDCs in the regulation of adaptive and innate immune responses, as well as translating this knowledge into therapeutic options.

Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry for Differentiation of the Dimorphic Fungal Species Paracoccidioides brasiliensis and Paracoccidioides lutzii

Isolates of Paracoccidioides brasiliensis and Paracoccidioides lutzii, previously characterized by molecular techniques, were identified for the first time by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). All isolates were correctly identified, with log score values of >2.0. Thus, MALDI-TOF MS is a new tool for differentiating species of the genus Paracoccidioides.

De novo transcriptome assembly for a non-model species, the blood-sucking bug Triatoma brasiliensis, a vector of Chagas disease

High throughput sequencing (HTS) provides new research opportunities for work on non-model organisms, such as differential expression studies between populations exposed to different environmental conditions. However, such transcriptomic studies first require the production of a reference assembly. The choice of sampling procedure, sequencing strategy and assembly workflow is crucial. To develop a reliable reference transcriptome for Triatoma brasiliensis, the major Chagas disease vector in Northeastern Brazil, different de novo assembly protocols were generated using various datasets and software. Both 454 and Illumina sequencing technologies were applied on RNA extracted from antennae and mouthparts from single or pooled individuals. The 454 library yielded 278 Mb. Fifteen Illumina libraries were constructed and yielded nearly 360 million RNA-seq single reads and 46 million RNA-seq paired-end reads for nearly 45 Gb. For the 454 reads, we used three assemblers, Newbler, CAP3 and/or MIRA and for the Illumina reads, the Trinity assembler. Ten assembly workflows were compared using these programs separately or in combination. To compare the assemblies obtained, quantitative and qualitative criteria were used, including contig length, N50, contig number and the percentage of chimeric contigs. Completeness of the assemblies was estimated using the CEGMA pipeline. The best assembly (57,657 contigs, completeness of 80 %, < 1 % chimeric contigs) was a hybrid assembly leading to recommend the use of (1) a single individual with large representation of biological tissues, (2) merging both long reads and short paired-end Illumina reads, (3) several assemblers in order to combine the specific advantages of each.

Alterações na estabilidade de agregados de latossolo e argissolo em função do manejo, na entrelinha da seringueira (Hevea brasiliensis)

A trial was carried out with the purpose of evaluating the effect of different management systems applied between the rows of rubber trees (Hevea brasiliensis) on the aggregate stability in water of Dark Red Latosol, with clayey texture from the Municipality of Jaboticabal (SP) and Yellow Red Podzolic, sandy/medium texture fromthe Municipality of Tabapua (SP). The treatments consisted of disk harrowing, Pueraria phaseoloides and mowing. The soil samples were withdrawn after seven years of application of these management systems from depths of 0-0.1, 0.1-0.2, 0.2-0.3, and 0.3-0.4 m. The stability of the aggregates was obtained in sieves with size classes of 8-4, 4-2, 2-1, 1-0.5, 0.5-0.125, and < 0.125 mm. The Pueraria phaseoloides gave a significant difference regarding the distribution of the aggregates on the superficial layer (10 cm) when compared to the other management systems, presenting a higher distribution of larger sized aggregates on the Dark Red Latosol. The tillage management for this same depth presented higher values of small sized aggregates on both soils. The organic matter on the soils showed a direct and significant relation to the stability of the larger sized aggregates and an inverse relation with the stability of the smaller sized aggregates.
