Oliveira Júnior, Ailton Paulo de;Morais, José Fausto de;
Ciência & Educa??o (Bauru) , 2009, DOI: 10.1590/S1516-73132009000300008
Abstract: this study aimed to build and validate a scale of attitudes of teachers of statistics towards statistics in the graduate courses in brazil. the validation of the scale of attitudes of teachers of statistics in relation to statistics (eape) had a sample of 87 teachers from seven brazilian states (distrito federal, rio grande do sul, paraná, santa catarina, s?o paulo, rio de janeiro and minas gerais) from institutions of higher education both public and private. factor analysis was performed for the experimental verification of dimensionality of eape, andfour factors were considered most appropriate. the factors taken were called cognitive, educational, emotional/social and conduct, with the cronbach alphas of 0.65, 0.68, 0.51 and 0.63, respectively. the scale showed a general internal consistency of 0.76.

Journal of Applied Oral Science , 2006, DOI: 10.1590/S1678-77572006000500016
Abstract: objective: the purpose of the present pilot study was to describe pain complaints of tmd patients and cervical spine dysfunction. methods: fourteen women with myogenous tmd, cervical motion limitation and rotation of at least one of the three first cervical vertebrae evidenced by radiographic examination participated in this study. the multidimensional pain evaluation was accomplished by a brazilian version of the mcgill pain questionnaire. results: the results showed that the most painful body site mentioned was cervical spine, followed by scapular region and temporomandibular joint. more than half of the volunteers reported temporal pain pattern as rhythmic, periodic and, or still, intermittent. the majority of the patients classified the pain intensity assessed at the moment of the evaluation as mild to discomforting. absolute agreement was not observed among volunteers regarding word dimensions used to describe their pain, although a great number of patients chose the descriptor related to tension as the better expression to describe their painful complaint. conclusion: pain characteristics of tmd patients with cervical spine dysfunction showed cervical spine as a common painful region reported and words related to affective and emotional dimensions of pain perception can be used by these patients to qualify their pain complain.

Abstract: background: the hemodynamic variability of air plethysmography is known in the literature, but the clinical significance of this event has not been investigated yet, and there may be some unexplored clinical meaning. there is known superpositioning of ceap clinical classes (c0-c6) and even in lower limbs of the same clinical classes. objective: to evaluate hemodynamic variability of air plethysmography parameters in ceap clinical classes. methods: this retrospective study compares lower limb varicose disease between c0 and c6 ceap clinical classes with venous hemodynamic parameters obtained by air plethysmography. data were tabled and analyzed according to their clinical classes by kruskal-wallys and barllet variance tests. results: a total of 310 examinations were performed in 230 patients, aged between 19-81 years (mean = 46.2 years). venous filling index and functional venous volume increased hemodynamic variability when compared with ceap c0. this was demonstrated by the variability coefficient, which was 28.12% for venous filling index in c0 and higher than 57% between clinical classes c2 and c6. ejection fraction and residual venous fraction had no increase in variability when compared with ceap c0. conclusion: venous filling index is the best parameter for assessment and screening patients with chronic venous insufficiency, but has great variability in c2 to c6 ceap clinical classes.

Interspecific chromosomal divergences in the genus Characidium (Teleostei: Characiformes: Crenuchidae)
Alves, José Carlos Pansonato;Paiva, Luiz Ricardo de Souza;Oliveira, Claudio;Foresti, Fausto;
Neotropical Ichthyology , 2010, DOI: 10.1590/S1679-62252010000100010
Abstract: karyotypes of seven fish species of the genus characidium, three of them studied for the first time, were characterized using conventional cytogenetic techniques (giemsa staining, ag-nor, and c-banding). all species presented a diploid number of 2n=50, with only metacentric and submetacentric chromosomes, as observed in all characidium species studied. in two species cells with one to three b chromosomes were observed. all species analyzed have a single nor-bearing chromosome pair with morphological differences among them. characidium cf. zebra shows heterochromatic blocks restricted to the pericentromeric regions of all chromosomes denoting the absence of a sex chromosome system. on the other hand, the species characidium lanei, c. pterostictum, c. lauroi, c. oiticicai, c. schubarti, and characidium sp., besides presenting pericentromeric heterochromatic blocks, exhibited large interstitial and/or terminal heterochromatic blocks, and a zz/zw sex chromosome system. the constitutive heterochromatin seems to play a relevant role in the chromosome differentiation process of the studied species, mainly in relation to the sex chromosomes. the geographical isolation of the rivers in which the species were sampled, associated with their way of life restricted to headwaters environments, may have favored the process of fixation of different karyotypes found in each of the analyzed species.

Abstract: cytogenetic analyses were performed in cyphocharax modestus, collected at paranapanema river and tietê river (s?o paulo state, brazil). a karyotype with 2n = 54 chromosomes was observed in the animals from both brazilian freshwater river systems. one to four b chromosomes were also detected in individuals from the paranapanema river, which represents the probable first report of more than a single supernumerary element in a species of the curimatidae group. c-banding revealed centromeric and telomeric heterochromatin blocks in several chromosomes of the normal karyotype complement of c. modestus. moreover, while some b chromosomes were characterized by the complete absence of c-bands, others were totally heterochromatic. although there was a prevalence of b chromosomes in males of c. modestus, at least one supernumerary element was found in males and/or females of several other populations of the species, which suggests that the presence of these chromosomes seems to represent a general trait of c. modestus. a possible origin of the described b chromosomes may be related to the occurrence of a chromosome non-disjunction followed by the loss of euchromatic segments, an event that should have occurred in chromosomes that present conspicuous centromeric heterochromatic blocks and even in chromosomes that lack c-bands in this region, resulting in small supernumerary elements.

Abstract: the 5s ribosomal dna (5s rdna) of higher eukaryotes is organized in repeat units of tandem arrays composed of a 5s rdna coding region, conserved even among non-related taxa, and a variable non-transcribed spacer sequence (nts). to contribute to knowledge on the organization and evolution of vertebrate 5s rdna we used pcr, nucleotide sequencing, southern blot hybridization and chromosome fluorescence in situ hybridization (fish) to investigate 5s rdna tandem repeats in the south american curimatidae fish steindachnerina insculpta and cyphocharax modesta. 5s rdna repeats of 180 base pairs (bp) from both species were pcr-generated and sequenced evidencing the shortest 5s rdna monomer so far described in eukaryote species. southern blotting revealed that both species contained two tandem 5s rdna classes, the pcr amplified fragment composed of 180 bp monomers and a class of 1600 bp monomers not detected by pcr. chromosome mapping of the 5s rdna repeats identified a major locus in both species and a second minor locus only in c. modesta. the southern blot and chromosome mapping data indicate the presence of different types of 5s rdna tandem repeats in the curimatidae genome.

Genetics and Molecular Biology , 2009, DOI: 10.1590/S1415-47572009005000075
Abstract: catfishes of the genus pseudoplatystoma are very important species due to both their high commercial value and their ecological role as voracious predators. they undertake lengthy migratory movements during their life-cycle, this including reproductive migration which occurs from october to december in the rainy season. in the present study, seven microsatellite loci were analyzed to access genetic variability in two samples of p. reticulatum from the upper paraguay basin. the loci were highly polymorphic (mean = 7.28). according to all analysis, the two samples of p. reticulatum revealed pronounced genetic differentiation. fst value was 0.2290, rst value 0.1067 and amova 22.90% (fst) and 10.67% (rst), all being highly significant (p < 0.001). the division of the fishes into two groups was confirmed by microsatellite multi-locus bayesian assignment testing. the results obtained present evidence of genetic structuring in a p. reticulatum population.
