Avaliação do perfil hematológico de portadores de talassemia alfa provenientes das regiões Sudeste e Nordeste do Brasil

A talassemia alfa é uma anemia hereditária resultante da síntese deficiente de cadeias alfa, provocando um excesso relativo de cadeias beta, que vão formar tetrâmeros identificados como hemoglobina H (Hb H) no indivíduo adulto. Para direcionar o diagnóstico laboratorial desta anemia, a análise dos índices eritrocitários, a eletroforese em acetato de celulose em pH neutro e a pesquisa de corpos de inclusão de Hb H são essenciais. O objetivo deste estudo foi traçar o perfil hematológico, por meio dos índices eritrocitários, dos portadores de talassemia alfa das regiões Sudeste e Nordeste do Brasil. Foram analisadas 1.010 amostras de sangue periférico após consentimento informado. Os índices eritrocitários como contagem de glóbulos vermelhos (RBC), dosagem de hemoglobina (HGB), hematócrito (HCT), volume corpuscular médio (VCM), hemoglobina corpuscular média (HCM) e concentração de hemoglobina corpuscular média (CHCM) foram fornecidos por aparelhos automatizados com controle de qualidade interno e externo. Para o diagnóstico de talassemia alfa foram utilizados testes de triagem e complementares para talassemias, como eletroforese em pH neutro e pesquisa de corpos de inclusão de Hb H com coloração de azul cresil brilhante. Comparando-se os valores hematológicos observados nos dois grupos, notou-se que, em ambas as regiões, os índices com valores discrepantes foram os níveis de HGB e HCT, sendo a maior freqüência de variação observada entre as mulheres. Nos portadores do fenótipo alfa talassêmico da região Nordeste, todos os índices eritrocitários estavam abaixo dos valores de normalidade. Estes resultados evidenciam a necessidade de melhor avaliação do perfil hematológico de talassemia alfa em diferentes regiões, considerando-se os interferentes ambientais para um diagnóstico mais preciso.

Formação de populações-bases de aves para corte. I. Avaliação de melhoramento genético disponível no mercado

The present work aimed at studying the effect of five doses of zinc (0, 1.0, 2.0, 3.0 and 4.0 ppm) in three levels of soil correction. A Dark-Red Latosol, clay texture, oryginally recovered by cerrado vegetation was used. Soybean was used as test plant, cultivated in green-house conditions. The zinc dose affected dry matter production of aerial parts and grain only in the treatments that received the corrective. The concentration of the element in the soil increased linearly with the dose application, and the critical levels in soil (90% of the maximal yield) were between 0.27 and 0.37 ppm of zinc in the treatments with the equivalent to 2.0 t/ha and 3.2 t/ha of lime, respectively.

Avaliação clínica e hematológica em bezerros Nelore infectados experimentalmente com isolados de Babesia bigemina das regiões Sudeste, Nordeste e Norte do Brasil

A comparative study was made regarding the clinical and hematological alterations caused by isolates of Babesia bigemina from southeastern, northeastern and northern Brazil in experimentally infected Nelore calves. Eighteen calves between 7 and 9 months of age, without antibodies against Babesia sp and raised free from ticks, were used. Three animals were previously inoculated with 2.0×109 parasitic erythrocytes (PE) for each stabilate. The other 15 calves were subdivided into three groups, with five animals each, that were subinoculated with 1.0×1010 PE of the respective isolates. The clinical and hematological alterations were evaluated by the determination of parasitaemia, haemogram, plasmatic fibrinogen, reticulocyte count, descriptive analysis of the bone marrow and erythrocytic osmotic fragility, for 30 days, totalizing seven moments of observation. The follow-up of the immunological response by the indirect fluorescent antibody test was carried out daily until the 10th day after inoculation (DAI) and after that, on the 15th, 20th, 25th and 30th DAI. A mild clinical manifestation of the disease was observed. The laboratory findings revealed low levels of parasitaemia; decrease of the erythrogram values; absence of reticulocytes, initial decrease in the total count of leukocytes, neutrophils and lymphocytes with a posterior elevation of the number of these cells; hypercellularity of the erythrocytic series and decrease of the myeloid: erythroid relation which was more accentuated between the 8th and 12th DAI, and an increase of the erythrocytic osmotic fragility in the groups inoculated with the Southeast and Northeast isolates. None of the three isolates of B. bigemina gave rise to the clinical characteristic form of the disease, although they induced an humoral immune response.

Comparação, em mulheres inférteis, de teste de avaliação psicológica com a análise psicanalítica clássica

This study aims to compare a psychological evaluation test to classical psychoanalysis in infertile women. Two hundred women were submitted to the Psychological Evaluation Test (PET). The sum of the scores for the responses ranged from 15 to 60 points, with scores ≥ 30 points being defined as psycho-emotional maladjustment (cut-off point: median + 25%). For comparison, a psychologist submitted the patients to a psychological examination simultaneously, who was unaware of the PET results. From the 200 patients, 66 (33%) presented a test with ≥ 30 points (psycho-emotional maladjustment) and 134 (67%) a test with < 30 points (normal). Upon psychological examination, 105 (52.5%) presented an abnormal evaluation and 95 (47.5%) a normal evaluation. For the PET, statistical analysis showed 82% efficiency, 62% sensitivity, 98% positive predictive value, 99% specificity, 70% negative predictive value, likelihood ratio for a positive test result 62, and likelihood ratio for negative test result 0.38. The PET proved to be a useful clinical instrument, being of help for the selection of patients with psychological needs induced by infertility.

Avaliação da formação do biofilme de Candida albicans sobre superfície de titânio revestida com hidroxiapatita por meio de microscopia eletrônica de varredura

In this study Candida albicans biofilm formation on the surface of commercially pure titanium (cp-Ti) coated with hydroxyapatite was observed by means of scanning electron microscope. The biofilm was formed after 45 days of incubation of the samples in liquid culture medium inoculated with fungus cells in a tube of polystyrene with screw cap and sterilized. After the biofilm removal with 10% EDTA solution was observed pitting on the surface of cp-Ti coated.

Facies sedimentares e ambientes deposicionais da Formação Barbalha no vale do cariri, bacia do araripe, nordeste do Brasil

The Aptian Barbalha Formation represents the first unit of the post-rift sequence of the Araripe Basin and crops out at the slopes of the Aranpe plateau in the eastern part ot Aranpe Basin. The unit has also been named Kio da Batateira Formation, but this name is here used in its original definition as Batateira Beds, an interval of great lateral continuity and characterized by the presence of bituminous shales of the Alagoas Stage (P-270 palynological biozone). This paper presents the results of a stratigraphic analysis carried out along the outcrop belt in order to establish the facies architecture and to interpret deposicional environments of the siliciclastic Barbalha Formation. Detailed stratigraphic vertical sections were measured and correlated. They allowed the recognition of two depositional sequences characterized by fining upward arrangement of facies, beginning with fluvial deposits and ending with lacustrine deposits at their tops. The end of the first cycle is represented by black shales and brecciated limestones of the Batateira Beds that record a geologic event of regional magnitude and serve as meaningful long-distance stratigraphic mark. The second deposicional sequence overlies disconformably the Batateira Beds and begins with clast-supported conglomerates, which are covered by a succession of fluvial sandstones and minor intervals of pelitic rocks. The sandstone content diminishes towards the top and the upper part of the unit is characterized by the presence of ostracode-rich green shales. The Barbalha Formation is conformably overlaid by Late Aptian lacustrine limestones belonging to the Crato Member of the Santana Formation.

Diques clásticos na formação corumbataí (p) no nordeste da bacia do paraná, SP: Análise sistemática e significações estratigráficas, sedimentológicas e tectônicas

This paper aims to present the results of systematic survey on clastic dykes in the Corumbataí Formation (Permian), in the northeast region of the State of São Paulo. Besides this, the paper analyses genetic aspects of those features as well as their stratigraphic and sedimentologic implications in terms of geologic evolution of the northeastern Paraná Sedimentary Basin during Permian times. The field works had been developed in 3 main Corumbataí Formation outcrops (2 road cuts and a quarry) supposed to show the most important clastic dikes occurrences in the studied area. Basically, the sedimentary intrusions are formed by fine sand or silt size particles and had penetrated host rocks as near-vertical, centimeter thick, dykes (most common form) or as horizontal sheets, forming clastic sills (subsidiary form), both with variable geometric forms and dimensions. A lot of dyke walls show undulations suggesting pre-diagenetic clastic intrusions, probably near the ancient depositional surface. Almost all intrusions occur in the superior third portion of the Corumbataí Formation and some similar features seem to appear in the adjoining superposed Pirambóia Formation base. In this article the authors defend a seismic origin hypothesis for the clastic intrusions. It is important to mention that clastic intrusions tend to occur linked to expressive seismic events, with magnitude upper to 5. The analysis of isopach maps of the Permian and Mesozoic units of the Paraná Sedimentary Basin in the study area suggests a depositional system changing, from epicontinental sea conditions to shallow platform and, finally, to coastal deserts. Probably, this environmental change was driven by regional uplift accompanied by seismic events. It is possible that ancient seismicity triggered liquefaction processes and the resulting clastic intrusions. In this sense, those clastic features might be properly namedseismites.
