Caracterização citogenética em Schlumbergera truncata (Haworth) Moran e Schlumbergera × buckleyi (T. Moore) Tjaden (Cactaceae)

O número cromossômico diplóide de Schlumbergera truncata e Schlumbergera x buckleyi, de indivíduos com diferentes tipos de coloração de pétalas, foi determinado usando-se pontas de raízes. A utilização de 8-hidroxiquinoleína 0,003 M à 36 °C por 3 horas possibilitou melhor separação cromossômica. Técnica de bandeamento C e de coloração Giemsa permitiram o estudo cariológico dessas espécies. O híbrido Schlumbergera × buckleyi (rósea) apresenta 2n = 22 cromossomos com fórmula cariotípica 16 M + 6 SM. Schlumbergera truncata, apresentando pétalas nas cores vermelha, branca e pink, possui 2n = 22 cromossomos, formulação cariotípica idêntica à de Schlumbergera × buckleyi, enquanto a planta com flores de coloração amarelada mostrou 2n = 34 cromossomos. A classificação cromossômica foi baseada no índice centromérico. Nas plantas que apresentam coloração vermelha, branca, pink e rósea nas pétalas, o melhor período de obtenção de metáfases corresponde ao período de florescimento. Schlumbergera truncata com flores amareladas apresenta dois picos anuais de divisão mitótica. Esses resultados dão suporte à um melhor entendimento da biologia no gênero Schlumbergera e auxiliam na classificação taxonômica nos casos onde apenas as características fenotípicas não são suficientemente confiáveis para a classificação das plantas no mesmo táxon.

Obsessive-compulsive disorder and personality disorder - Evidence from the British National Survey of Psychiatric Morbidity 2000

Background Previous studies indicate that most individuals with obsessive-compulsive disorder (OCD) have comorbid personality disorders (PDs), particularly from the anxious cluster. However, the nature and strength of this association remains unclear, as the majority of previous studies have relied heavily on clinical populations. We analysed the prevalence of screen positive personality disorder in a representative sample of adults with OCD living in private households in the UK. Methods A secondary analysis of data from the 2000 British National Survey of Psychiatric Morbidity. The prevalence of PD, as determined by the SCID-II questionnaire, was compared in participants with OCD, with other neuroses and non-neurotic controls. Within the OCD group we also analysed possible differences relating to sex and subtypes of the disorder. Results the prevalence of any screen positive PD in the OCD group (N = 108) was 74%, significantly greater than in both control groups. The most common screen positive categories were paranoid, obsessive-compulsive, avoidant, schizoid and schizotypal. Compared to participants with other neuroses, OCD cases were more likely to screen positively for paranoid, avoidant, schizotypal, dependent and narcissistic PDs. Men with OCD were more likely to screen positively for PDs in general, cluster A PDs, antisocial, obsessive-compulsive and narcissistic categories. The presence of comorbid neuroses in people with OCD had no significant effect on the prevalence of PD. Conclusions Personality pathology is highly prevalent among people with OCD who are living in the community and should be routinely assessed, as it may affect help-seeking behaviour and response to treatment.

Spatial distribution of dengue in the city of Cruzeiro, São Paulo State, Brazil: use of geoprocessing tools

Este artigo tem por objetivo identificar padrões na distribuição espacial dos casos de dengue ocorridos no município de Cruzeiro/SP, no ano de 2006. Trata-se de um estudo ecológico e exploratório que utiliza as ferramentas de análise espacial na elaboração de mapas temáticos, com dados obtidos do SinanNet. Foi feita uma análise por área, tomando-se como unidade o setor censitário do IBGE; a análise considerou quatro meses do ano de 2006 que mostra a ocorrência da doença no município. Os mapas temáticos foram construídos pelo programa computacional TerraView 3.3.1; assim como os valores dos índices de Moran Global (I M) mês a mês e o estimador de Kernel. Foram georreferenciados 691 casos de dengue (taxa de 864,2 casos/100.000 habitantes); os Índices de Moran e p-valores obtidos foram I M = 0,080 (março) p = 0,11; I M = 0,285 (abril) p = 0,01; I M = 0,201 (maio) p = 0,01 e I M = 0,002 (junho) p = 0,57. Os primeiros casos foram identificados na região nordeste e central e os últimos casos, na região norte, nordeste e central. Foi possível identificar os setores censitários onde a epidemia teve início e como ocorreu têmporo-espacialmente no município.

SPATIAL AUTOCORRELATION OF MORPHOMETRIC VARIATION IN LUTOSA-BRASILIENSIS (BRUNNER VONWATTENWYL, 1888) (ORTHOPTERA, GRYLLACRIDOIDEA, HENICIDAE)

Geographic differentiation and sexual dimorphism in eighteen morphometric characters of Lutosa brasiliensis (Orthoptera: Henicidae) collected in eight localities of the State of São Paulo (Brazil) were analysed. A two-way Multivariate Analysis of Variance (MONOVA) was used to assess simultaneously the effects of sex and geographic location (plus their interaction) on morphometric variability. The spatial patterns of variation were analysed by Factor and Spatial Autocorrelation Analyses (Moran's I coefficient in four distance classes). Both indicate that the main direction of variation is, for males and females, a north-south cline in overall body size. In females, however, ovipositor length is not correlated with overall body size and displays a different pattern of variation over geographic space, indicating that distinct evolutionary forces produced the geographic differentiation in the species.

Heritability of sting characters in Africanized honeybees

In this paper we proposed to estimate the heritability of seven morphological characters that compose the sting apparatus ofthe Africanized honeybee workers. An experimental design to estimate genetic parameters was based on the method developed by Oldroyd and Moran. This method was modified to eliminate within-colony environmental effects associated with the additive genetic variance. The estimated h2 values ranged from 0.17 ± 0.11 (maximum width of bulb of sting stylet and height of the valve of right lancet) to 0.74 ± 0.30 (length of the lancet).

Rhabdomyomatous carcinoma of the thymus

Myoid cells have been described in the thymus in association with a variety of benign and malignant conditions. The presence of a benign rhabdomyomatous component in a malignant primary thymic epithelial neoplasm, however, is extremely rare. A case of poorly differentiated carcinoma of the thymus arising in the posterior mediastinum containing a prominent rhabdomyomatous component is described. The patient, a 70-year-old woman, was seen for a large posterior mediastinal mass. An open chest biopsy revealed an extensively necrotic tumor composed of islands of atypical cells with vesicular nuclei and prominent nucleoli with numerous mitotic figures admixed with abortive glandular structures. Interspersed with the malignant epithelial components were islands of large cells containing brightly eosinophilic cytoplasm and small, round, excentrically placed nuclei. Immunohistochemical studies showed strong positivity of the epithelial cells for cytokeratin and strong positivity of the myoid cells for pan-actin, desmin, and myogenin. The possible relationship of the rhabdomyomatous component of this tumor with the myoid cells of the thymus is discussed.

Autocorrelação espacial em população natural de Terminalia argentea Mart et Succ. no cerrado de Selvíria, MS

The objective of this study was determine the spatial distribution of genotypes of Terminalia argentea Mart et Suce. (Capitão-do-campo) in a natural population, aiming to outline strategy to genetic conservation in situ and ex situ. The population (Terminalia argentea) is located in an area of cerrado on the Teaching and Research Farm of FEIS / UNESP. It was sampled seeds in 30 trees to determine the biochemistry and technological traits. The trees were also located per GPS apparatus, with objective of obtaining geographic coordinate and to analysis the genotype spatial structure from I Moran Index. The analysis of spatial autocorrelations, from I Moran index, indicated the tendency of a larger structure among trees near spatially. In another hand, trees distant spatially showed smaller similarity. The spatial structure was more visible in a ray of 353m.
