Relação peso/largura da carapaça e fator de condição em Dilocarcinus pagei Stimpson (Crustacea, Trichodactylidae), em São José do Rio Preto, São Paulo, Brasil

A biologia de caranguejos de água doce tem sido pouco enfocada na literatura carcinológica, especialmente em relação à Dilocarcinus pagei Stimpson, 1861. Este estudo visa analisar a relação peso/tamanho e variações temporais/sazonais do fator de condição, comparando com a biologia da espécie. Os exemplares foram coletados mensalmente na Represa Municipal de São José do Rio Preto (São Paulo), durante um período bianual (outubro/1994 a setembro/1996). Foram obtidos 962 espécimes (534 machos e 428 fêmeas), que foram mensurados (LC = largura do cefalotórax) e pesados (PE = peso úmido total). Os pontos empíricos da relação PE/LC foram analisados para cada sexo e submetidos à análise de regressão pela função potência (y = ax b) e representadas por: PE Machos = 0,0002LC3,º8 e PE Fêmeas = 0,0005LC2,82. O fator de condição foi calculado mensal e sazonalmente, sendo o das fêmeas cerca de 2,5 maior que o dos machos, possivelmente devido ao maior tamanho/peso das gônadas. de modo geral o verão foi caracterizado pela menor média de fator de condição (época reprodutiva), contrastando com a maior verificada no inverno (reorganização gonadal). Os resultados obtidos são enfocados pela primeira vez na literatura carcinológica, sendo de grande valia no manejo populacional e preservação desta espécie, que vem sendo intensamente explorada e usada como isca na pesca esportiva.

Lianas da estação ecológica do Noroeste Paulista, São José do Rio Preto/Mirassol, SP, Brasil

Lianas são membros característicos das florestas tropicais, onde são abundantes e de grande importância ecológica. Entretanto, têm sido negligenciadas em estudos florísticos e fitossociológicos. Este trabalho apresenta as espécies de lianas da Estação Ecológica do Noroeste Paulista (EENP) e as compara àquelas encontradas em outros fragmentos florestais. A EENP (20º48'36'' S e 49º22'50'' W) está a 468 m de altitude e abrange área de 168,63 ha, composta de três fragmentos de vegetação descontínua, classificada como floresta estacional semidecidual, entremeadas por pastagens. As amostras de lianas foram coletadas realizando caminhadas na periferia e no interior da mata. Foram identificadas 105 espécies; delas, 99 são Magnoliopsida (60 gêneros e 22 famílias); e seis, Liliopsida (três gêneros e três famílias). As famílias mais ricas em espécies representaram 59% do total das lianas. A análise do dendrograma de similaridade mostrou que esta é baixa entre a Floresta Atlântica de São Paulo e aquelas localizadas no interior. Situação semelhante foi observada por outros autores na análise de similaridade com espécies de porte arbóreo, e também, entre florestas do interior e Floresta Atlântica.

Detecção e conscientização de portadores de hemoglobinopatias nas regiões de São José do Rio Preto e Presidente Prudente, SP (Brasil)

Foram analisadas 7.657 amostras de sangue provenientes de 48 cidades das regiões de São José do Rio Preto e de Presidente Prudente, com o objetivo de detectar e conscientizar os portadores de hemoglobinas anormais. As análises efetuadas mostraram que 3,47% tinham hemoglobinas anormais, sendo 2,26% portadores de variantes moleculares (Hbs, AS, AC, SS, SC, AJ, AB2) e 1,21% de talasse-mias (alfa e beta). Os resultados obtidos evidenciaram que estudos semelhantes, além de propiciar o melhor conhecimento das causas genéticas, bioquímicas e hematológicas dessas alterações hereditárias, oferecem também a oportunidade de estimar a importância que essas patologias representam para a saúde pública do nosso país. A ação preventiva foi estabelecida por meio de reuniões de esclarecimentos médicos e biológicos aos portadores de hemoglobinas anormais.

The 3.4-3.5 Ga Sao Jose do Campestre massif, NE Brazil: remnants of the oldest crust in South America

The oldest fragment of continental crust recognized in South America occurs as an isolated Archean enclave in northeastem Brazil's Borborema Province, ca. 600 Ma Brasiliano-Pan African orogenic belt. This Archean fragment, the Sao Jose do Campestre massif, is surrounded by large tracts of 2.2-2.0 Ga Paleoproterozoic gneisses and is located more than 600-1500 km from the much larger assemblages of Archean rocks found in the Sao Fransciso and Amazonian cratons, located to the south and west, respectively. Geochronological studies of the Sao Jose do Campestre massif show that its oldest rocks contain zircons with U-Pb ages up to 3.5 Ga and Sm-Nd T-DM model ages of more than 3.7 Ga, indicating that they represent reworked crust. This older nucleus is flanked by both reworked and juvenile 3.25 and 3.18 Ga rocks which arc intruded by both 3.00 and 2.69 Ga plutonic bodies. The protracted evolution the Sao Jose do Campestre massif is consistent with that of a larger continental mass as opposed to a small crustal fragment that grew in isolation. As such, the Sao Jose do Campestre massif is interpreted as representing a detached piece of an evolved craton that became entrained with younger rocks during a subsequent Paleoproterozoic accretionary-orogenic event. This hypothesis is bolstered by the presence of Paleoproterozoic gneisses that envelop the Sao Jose do Campestre massif, as well as the existence of ca. 2.0 Ga metamorphic zircon and monazite within its rocks. The occurrence of several different Archean cratonic basement inliers within the greater Paleoproterozoic crustal framework of the Borborema Province suggests that cratonic slices spalled off one or more larger Archean masses prior to the ca. 2.2-2.0 Ga Paleoproterozoic orogenic collage. A important challenge is to link these older fragments to their parent cratons. Although results are not unique, the pattern of ages and isotopic signatures observed in the Sao Jose do Campestre massif is similar to that seen in parts of the Sao Francisco Craton, and it is possible that the Sao Jose do Campestre massif is a fragment of an Archean continental fragment formed during an episode of continental breakup prior to 2200 Ma.

Sulfur and carbon isotopes in scapolite-bearing granulites of the São José do Rio Pardo area, Brazil

Sulfur and carbon isotope compositions of ten scapolites from granulite-facies rocks of the São José do Rio Pardo area, Guaxupé Complex, Brazil, were measured. Scapolite is the primary and major rock-forming mineral in these rocks (up to 40 volume %). The isotopic composition of the sulfate and carbonate group in the scapolite structure has δ34S values of +1.0‰ to +6.7‰, and δ13C values of -14.3‰ to -6.3‰, respectively. The sulfur isotope data may be related to an upper mantle (external) or lower crustal (internal) source for the sulfur, whereas the carbon appears to have been derived from an internal source. Thus, the carbon and sulfur isotope data can be explained without invoking an external (mantle) source. © 1993.

Mortalidade por causas externas no Município de São José do Rio Preto, no período de 1996-1998

Introduction: An epidemiological study of the mortality rates by injuries in São José do Rio Preto, State of São Paulo, Brazil, has been carried out. The period considered is 1996-1998. Objectives: To show injuries mortality rates in São José do Rio Preto-SP in 1996-98. Methods: The study was based on official data from the Mortality Information Service of the Brazilian Ministry of Health, and in a survey based on data from medical forensic examiners (IML). Software Epinfo6.0 and Tabwin was utilized for data analises. Results: The results were compared to values obtained in the literature for the other cities of São Paulo and Brazil. In the case of São José do Rio Preto, was observed a decrease in the number of deaths associated with external causes in the period, but particularly in deaths due to traffic accidents with motor vehicles an increase in cases of pedestrians killed by hit-and-run drivers, that is much larger than the corresponding values for Brazil and for the State of São Paulo. The study showed increase in rates of homicides, mainly in the 15 to 39 years age group. Conclusion: This result suggests that is important to start programs to reduce the number of deaths by injuries, as well as the necessity of monitoring locally all these data.

The auto-radiography was applied to detect the presence of radioactive minerals in some samples of schists and gneisses from the Ticunzal Formation, Northeast Goiás State, aiming to implement the use of this technique in LABIDRO - Hydrochemistry and Isotopes Laboratory of the Department of Petrology and Metallogenesis, State University of São Paulo/Campus of Rio Claro.

Eritrograma e medição dos eritrócitos de avestruzes (Struthio camelus) em Sãojosé do Rio Preto-SP, Brasil

Ostriches' erythrocytic parameters help on the diagnosis of specific pathologies and serve as basic knowledge for studies in comparative avian pathology. To obtain reference values of erythrocyte indices for ostriches (Struthio camelus) raised in a commercial system in Brazil and verify if there are differences between gender and age groups, 240 healthy from both sexes animals were bled. Heparinized blood samples were analyzed using standard techniques to determine the red blood cell (RBC) count, hemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) values, besides the red cell morphometry analysis using a computer software that calculates the greater and the smaller diameters of the erythrocytes. Prior to data analysis, ostriches were divided into three different age groups: from four to 13 months, from 13 to 23 months and from 23 to 30 months the. Younger ostriches presented lower erythrocyte indices than the older ones. The age group effect was only significant in females for the erythrocyte, hemoglobin, MCV, MCH, and MCHC variables. The female ostriches presented PCV, MCV, MCH, and MCHC values significantly higher than males in some age groups. It was observed that the erythrocytes of the female ostriches are more elongated and larger than males. It was concluded that erythrocytic parameters of ostriches in São José do Rio Preto-SP, Brazil are influenced by gender and age, highlighting the importance of consider besides these factors also the geoclimatic conditions to an adequate interpretation of the erythrogram.

Detecção de anticorpos anti-leishmania infantum syn chagasi em cães de São José do Rio Preto, São Paulo

Visceral leishmaniasis (VL) has been a widespread zoonosis in São Paulo since 1998, when the first autochthonous canine case was identified in Araçatuba. The aim of this study was to determine the occurrence of anti-Leishmania infantum syn chagasi antibodies in serum samples of 584 dogs from São José do Rio Preto, São Paulo, a non endemic area for the disease. Five dogs (0.86%) seroconverted by ELISA and one (0.17%) by immunochromatography. The indirect immunofluorescent reaction, carried out in 138 animals whose optical densities were above or close to ELISA's cutt-off point, evidenced two dogs (1.45%) with titers above 1:40. Only one dog was serum-reactive on the three techniques. Although there was not a history of displacing this animal to endemic areas, the dog had been acquired in a region with canine and human cases of VL. These results suggests that there were no autochthonous cases of canine VL in this population.

Geochemical and radioactivity characterization of rocks from the Rio Preto (Go) Project

The Rio Preto Project, developed by the extinct Brazilian nuclear state company, Nuclebrás, during the late 70s and early 80s, consisted of basic geological mapping and radiometric characterization by aerogeophysical gamma-ray spectrometry, without channel discrimination, of a surface area of 650 km2 located to the west of the Chapada dos Veadeiros National Park on the northeastern of Goiás State, Brazil, including the confluence area of Claro and Preto Rivers. Additionally, the natural radioelements U, Th and 40K were determined by gamma-ray spectrometry in 300 rock samples from cores of the Rio Preto Project area. The tests were conducted at LABIDRO-Isotopes and Hydrochemistry Laboratory of the Departament of Petrology and Metallogeny (DPM) of the Institute of Geosciences and Exact Sciences, UNESP, in Rio Claro, SP, Brazil. This paper reports the results of petrographic characterization and chemical analyses of major oxides (SiO2, TiO2, Al2O3, Fe2O3, MgO, MnO, K2O, Na2O, CaO and P2O5) for all samples used to determine the natural radioelements present in the region. The organic matter content results obtained by colorimetry are also reported for selected cores of different lithotypes in order to investigate the possible relationship between graphite and the radioelements uranium and thorium. Finally, uranium content and 234U/238U activity ratio data for selected samples of schists and gneisses of the Lower Member of the Ticunzal Formation suggest the influence of weathering processes in the area. © 2012 Sociedade Brasileira de Geofísica.
