O objetivo deste estudo foi descrever as espécies da subtribo Cranichidinae ocorrentes no Paraná, devido a pouca informação disponível sobre sua flora. Oito espécies de Cranichidinae coletadas em 38 localidades foram encontradas a partir de análises de espécimes de herbários. Cranichidinae são ervas terrestres, com folhas sésseis a pecioladas, inflorescência racemosa e flores não ressupinadas, normalmente verdes ou brancas. Baskervilla Lindl., representada apenas por B. paranaensis (Kraenzl.) Schltr., possui labelo saciforme projetado para trás em bolsa arredondada e pétalas unguiculadas. Cranichis Sw. possui labelo cocleado, branco com manchas verdes, e o gênero é representado por C. muscosa Sw. e C. candida (Barb.Rodr.) Cogn.. Prescottia é o gênero mais diverso, com cinco espécies, P. densiflora (Brongn.) Lindl., P. lancifolia Lindl., P. oligantha (Sw.) Lindl., P. montana Barb. Rodr. e P. stachyodes (Sw.) Lindl., e pode ser reconhecido por possuir labelo calceolado com margens involutas. Cranichidinae ocorrem principalmente em Estepe Ombrófila e Floresta Ombrófila Densa. Baskervilla paranaensis, C. muscosa, P. lancifolia e P. montana são consideradas espécies ameaçadas no Paraná. Cranichis candida, Prescottia epiphyta Barb. Rodr., P. microrhiza Barb. Rodr., P. pubescens Barb. Rodr. e P. nivalis Barb. Rodr. tiveram seus lectótipos determinados. Prescottia epiphyta é considerada como sinônimo novo de P. lancifolia e P. microrhiza e P. nivalis sinônimos de P. oligantha.

Hevea brasiliensis (Willd. Ex Adr. Juss.) Muell.-Arg. is the primary source of natural rubber that is native to the Amazon rainforest. The singular properties of natural rubber make it superior to and competitive with synthetic rubber for use in several applications. Here, we performed RNA sequencing (RNA-seq) of H. brasiliensis bark on the Illumina GAIIx platform, which generated 179,326,804 raw reads on the Illumina GAIIx platform. A total of 50,384 contigs that were over 400 bp in size were obtained and subjected to further analyses. A similarity search against the non-redundant (nr) protein database returned 32,018 (63%) positive BLASTx hits. The transcriptome analysis was annotated using the clusters of orthologous groups (COG), gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Pfam databases. A search for putative molecular marker was performed to identify simple sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs). In total, 17,927 SSRs and 404,114 SNPs were detected. Finally, we selected sequences that were identified as belonging to the mevalonate (MVA) and 2-C-methyl-D-erythritol 4-phosphate (MEP) pathways, which are involved in rubber biosynthesis, to validate the SNP markers. A total of 78 SNPs were validated in 36 genotypes of H. brasiliensis. This new dataset represents a powerful information source for rubber tree bark genes and will be an important tool for the development of microsatellites and SNP markers for use in future genetic analyses such as genetic linkage mapping, quantitative trait loci identification, investigations of linkage disequilibrium and marker-assisted selection.

The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. Once psychogenic seizures were diagnosed and psychiatric treatment was started, seizures stopped.

In this paper a water quality index is developed to subsidize management actions in the Atibaia River for upon protection of aquatic organisms. This index is composed of two measurable environmental parameters normaly, ammonia and dissolved oxygen, the latter representing the contribution of organic matter. Concentrations of these two variables were normalized on a scale from 0 to 100 and translated into statements of quality (excellent, good, regular, bad and very bad). The index was applied to three monitoring points in the Atibaia River and compared to other indices used by the State of São Paulo Environmental Agency (CETESB). The results showed that the degradation in this watershed follows the urban population density. The developed index is more restricted than the other ones routinely used to infer water quality.

In this work a simple and sensitive procedure to extract organic mercury from water and sediment samples, using methylene chloride in acidic media followed by CVAFS quantification has been developed. The method was evaluated for possible interferents, using different inorganic mercury species and humic acid, no effects being observed. The detection limit for organic mercury was 160 pg and 396 pg for water and sediment samples respectively. The accuracy of the method was evaluated using a certified reference material of methylmercury (BCR-580, estuarine sediment). Recovery tests using methylmercury as surrogate spiked with 1.0 up to 30.0 ng L-1 ranged from 90 up to 109% for water samples, whereas for sediments, recoveries ranged from 57 up to 97%.

The first idea of this study is trat there may be a disturbance of the visuo-spatial function in cerebral palsy. This idea is based upon the theories of Luria and Piaget. The second idea of this study is that the computer can help the investigation of visuo-spatial function. With the intention of evaluating the spatial function in cerebral palsy, the literature related to these themes was revised. We justify the proposal of a new test to study visuo-spatial function. This test uses straight lines in four different orientations and the subject has to recognize and arrange them individually or sets of them. This was done through the use of pencil and papel, and computer. The results confirm that there is a spatial disturbance and that a better understanding of the subject's difficulties was made possible through the use of the computer and the Logo computer language.

Este trabalho avaliou o material de higiene bucal usado em escolas para estabelecer um protocolo às ações de higiene bucal coletiva. O estudo foi dividido em duas etapas: 1ª- 20 responsáveis pelos procedimentos coletivos com escolares de Bauru e São José dos Campos - SP responderam a dois questionários sobre o uso de cinco kits de higiene bucal coletiva. A análise estatística foi realizada através do teste Wilcoxon (p < 0,05); 2ª - 178 escolares de 4 a 8 anos de Bauru e Bariri-SP dispensaram na escova uma quantidade de creme dental e dentifrício líquido para a prática da escovação, a qual foi pesada através de uma balança portátil. A análise estatística foi obtida através do coeficiente de correlação de Pearson e a análise de covariância (p< 0,05). O kit 5 obteve graus de satisfação e muita satisfação quando comparado aos kits 1 a 4. A quantidade de creme dental dispensada pelos escolares foi em média 0,41g (Bauru) e 0,48g (Bariri). Não houve diferença estatística entre os escolares de Bauru e Bariri em relação ao dentifrício líquido (média de 0,15g). O dentifrício líquido, através da "técnica da gota", foi considerado prático, dispensando uma pequena quantidade padronizada. O kit 5 demonstrou ser uma boa alternativa ao estabelecimento de um protocolo de ações em saúde bucal coletiva no SUS.

The use of thermoanalytical data in sample preparation is described as a tool to catch the students' attention to some details that can simplify both the analysis and the analytical procedure. In this case, the thermal decomposition of eggshells was first investigated by thermogravimetry (TGA). Although the classical procedures suggest long exposure to high temperatures, the TGA data showed that the decomposition of organic matter takes place immediately when the sample is heated up to 800 °C under air atmosphere. After decomposition, the calcium content was determined by flame atomic emission photometry and compared with the results obtained using classical volumetric titration with EDTA.
