A prescrição abusiva de medicamentos na odontologia constitui um desafio aos programas de saúde pública que visam corrigir a prescrição inadequada de fármacos. Os anti-inflamatórios não esteróides (AINE) podem alteram a eficácia dos anti-hipertensivos, elevando a pressão arterial, sobretudo em pacientes idosos e/ou com hipertensão arterial sistêmica (HAS). O objetivo foi avaliar o nível de conhecimentos dos cirurgiões-dentistas (CD) da rede pública da saúde da Prefeitura Municipal de São José dos Campos (PMSJC) sobre a prescrição de AINE a pacientes com HAS. Trata-se de estudo descritivo, realizado por meio de questionário aplicado aos 92 CD da PMSJC. Os resultados foram analisados estatisticamente utilizando-se os testes de Wald e de Fisher. A associação entre as variáveis foi estudada por meio da razão de chances (OR) com p-valor<0,05. Os resultados mostraram que o nível de conhecimento para a prescrição de AINE para pacientes com HAS foi insuficiente e as interações medicamentosas entre AINE e anti-hipertensivos são desconhecidas pela quase totalidade da amostra. Concluiu-se que os cursos de atualização em odontologia não estão suprindo as necessidades dos CD no âmbito da farmacoterapia.

Este estudo tem como objetivo analisar a atenção à saúde da criança pelo Programa de Saúde da Família (PSF) do município de Teixeiras, MG, Brasil. Foi aplicado um questionário a 161 mães de crianças menores de dois anos. Utilizou-se um sistema de escores específicos para análise das dimensões de estrutura, processo e resultado e seus respectivos atributos, classificando o município nos cenários incipiente, intermediário e avançado. Configurou-se, na síntese, um cenário intermediário (49,6%) para o PSF, caracterizado por uma atenção à saúde da criança fragmentada, mas com avanços na organização da atenção para este grupo. Foram consideradas incipientes as instalações físicas, a qualidade do cuidado no controle da diarréia e das infecções respiratórias, a participação comunitária e a intersetorialidade. Os avanços estiveram relacionados ao acolhimento realizado pelo programa, no entanto, as atividades preventivas e promocionais do PSF demonstram que o programa surge como um suporte do hospital e mais um local de atendimento médico. A atuação do PSF na atenção a saúde das crianças distancia-se da proposta de reorientação do modelo assistencial hegemônico, pela qual foi criado, dificultando estratégias na prevenção de doenças e na promoção da saúde.

Cytogenetic studies were performed on two sympatric species of Characidium, C. gomesi and C. cf. zebra, from the Grande River basin, Minas Gerais State, Brazil. Although both species had a chromosome number of 50 with a karyotype exclusively consisting of meta- and submetacentric chromosomes, interspecific diversity was detected concerning the size of the two first chromosome pairs of the karyotypes. Active nucleolus organizer regions (NORs) were located at the terminal position on the long arm of the 17th pair of C. gomesi and at subterminal position on the long arm of the 23rd pair of C. cf. zebra. For both species the fluorochrome CMA3 stained only the NOR-bearing pair of chromosomes. The heterochromatin pattern also showed some differentiation between these species restricted to the centromeric or pericentromeric region of C. cf. zebra and practically absent in C. gomesi. These data are discussed concerning chromosome diversification in this fish group.

Objetivou-se com este estudo avaliar os impactos ambientais causados por um sistema de cultivo de camarões marinhos em tanque-rede sobre a qualidade da água e sobre a estrutura da comunidade zooplanctônica. O estudo foi realizado na Baía de Guaratuba, onde os cultivos eram realizados em 300 tanques-rede (3,6 m de comprimento, 3,6 m de largura e 2 m de profundidade) distribuídos em uma área de 4.200 m², em densidade de 720 camarões/m². As concentrações de amônia, nitrito e fosfato na água foram monitoradas e amostras de zooplâncton foram coletadas no local dos cultivos (ponto 1) e em outros três pontos localizados a aproximadamente 200 m para oeste, noroeste e sudeste dos tanques. O ponto 5, usado como controle, localizava-se a aproximadamente 1.000 m a sudoeste da área de produção. As concentrações de nitrogênio amoniacal, nitrito e fosfato não diferiram entre os pontos amostrados, assim como a estrutura da comunidade zooplanctônica, que foi semelhante entre os pontos amostrados. Não foram evidenciados impactos significativos do empreendimento sobre a qualidade da água ou sobre estrutura das comunidades zooplanctônicas no local do cultivo e em áreas adjacentes, durante o período em que a investigação foi conduzida.

Platinum-Pd nuggets from the Born Sucesso stream alluvium Minas Gerais, Brazil. have been investigated by electron-probe microanalysis. The nuggets attain 1 mm in maximum dimension and have a botryoidal habit, with pronounced compositional core-to-margin zoning of internal structures, Although there is a wide variation in internal morphology and individual zones vary markedly in thickness (<1-100 mum), a typical composite arborescent nugget comprises a broad irregular core region of massive auriferous Pd-Hg alloy (potarite delta-PdHg) or cavity space + relict potarite enclosed by a narrow zone of platiniferous, palladium or alloy of near Pt50Pd50 composition, and is progressively oscillatory zoned by palladian platinum, with growth eventually enveloping the whole botryoidal colony, to a narrow rim of palladian platinum or pure platinum. Other nuggets comprise an arborescent to dendritic core of auriferous potarite, a broad internal zone of either pure platinum or palladian platinum, and a narrow rim of platinum, the mineral palladium contains up to about 65 at.% Pd; this is the first detailed modern confirmation of palladium in its type locality. Auriferous potarite ranges in composition from similar toPd(3)Hg(2) to near Pd(Hg,Au). The origin of these nuggets remains unclear, but their mineralogy is broadly equivalent to that of palladian gold. potarite and platinum in alluvial sediments and overburden from Devon, England, which are considered to be detrital, and their platinum-group-clement geochemistry is consistent with precipitation from hydrothermal fluids. We suggest that the Bom Sucesso nuggets resulted from high-level episodic hydrothermal alteration of mafic and ultramafic rocks within the drainage basin, with the remobilized Pt and Pd precipitated in open spaces in the enclosing metaquartzites.

This article analyzes the degree of thermopluviometric influence on certain indicators in the commerce of Maringa, state of Parana. To the end, climate elements, such as the temperature and prectipitation as well as certain economic indicators, namely: ICMS (taxes), SCPC, Video-Check, Consumption and Consumers of Electric Energy were studied. Graphical analyses along with statistical applications of correlation and regression were performed, as well as the examination of a case study. It is believed that the groups investigated showed variations in the forms of correlation. The results herein presented are in the manner of preliminary trial, representing a first attempt at measuring the actual relationship between the climatic variables (temperature and precipitation) with certain behavioural indicators of commerce in the city of Maringa.

We studied the distribution of birds along an altitudinal gradient ranging from 800 m to 1,400 m on two slopes of the Serra do Cip6, Minas Gerais, southeastern Brazil. Ornithological surveys were conducted over transects covering open (cerrado, campo rupestre) and forested (gallery and Atlantic forest) habitats from 1994 to 2000. We found 273 bird species belonging to 51 families. Twenty-two species were restricted to higher elevations and 84 Species were detected on only one slope, depending on the vegetation type they inhabited. We recorded 104 species occurring on both slopes, while 61 species were considered altitudinal generalists. Six species, including Hyacinth Visorbearer Augastes scutatus and Cip6 Canastero Asthenes luizae were restricted to the highest parts of Serra do Cip6, a fragile habitat important to endemic birds of the Espinhaco Range. In the past 10 years, the Serra do Cip6 region has suffered human impacts on a large scale, and conservation action must be developed to protect the fauna and flora confined to the area.

The morphological and anatomical leaf and scape differentiation of Leiothrix crassifolia is analysed and classified into seven types (I, II, III, IV, V, VI, Vn). The species has a relatively wide distribution in the campo rupestre of Minas Gerais in Brazil. Variation in the isolated populations on different mountain ranges is complex, does not follow a clear geographical pattern, and defies taxonomic classification. L. nubigena and L. obtusifolia are included in L. crassifolia.

The mafic/ultramafic Ipanema Layered Complex (ILC), Minas Gerais Brazil, consists of seven individual bodies. These units crosscut polyphase orthogneisses and interlayered paragneisses of the Paleoproterozoic Juiz de Fora Complex. Intrusive granitoids tectonically related to [lie Neoproterozoie Aracuai orogen are also present in the study area.A Sm-Nd whole-rock linear array for seven samples metapyoxenites, metaperidotiles, metagabbro. and meta-anorthosite) from the Santa Cruz massif, the largest body of the ILC. suggest that it was emplaced at 1104 +/- 78 Ma the original magma was derived from a depleted mantle source (epsilon(Ndt)= +3.8). U-Pb single-grain zircon stud of a meta-anorthosite yields all upper intercept age of 1719 +/- 4 Ma, which is interpreted to represent inheritance. The lower intercept at 630+/-3 Ma indicates (hat a Neoproterozoic tectonothermal episode overprinted the ILC, this event occurred under upper-amphiolite-, to granulite-facies conditions. The 630 Ma episode is consistent with the timing of regional metamorphism and deformation of the adjacent Aracuai orogen (Brasiliano collage). Emplacement of the ILC and other coeval metamafies and meta-ultramafics (of alkaline affinity) in the re, oil is attributed to early extension tectonics, accompanying accretion of the Rodinia super- continent during the Mesoproterozoic-Neoproterozoic time boundary.

The Santa Cruz massif, which forms part of the Ipanema mafic/ultramafic Complex, Minas Gerais, Brazil, has an exposed upward sequence of metadunite, metaharzburgite (including three separate chromitite layers), metapyroxenite, metagabbro, and metaanorthosite. Primary igneous chromite grains in the main chromitite layer are poikiloblastic and tectonically fragmented, and have a narrow (10-20 mum) margin of chromian spinel. Cataclased chromite fragments are extensively replaced and mantled by chromian spinel; they have a composite margin comprised of an inner zone of more aluminous spinel and an euhedral outer zone of more Cr-rich spinel, representing granulite and amphibolite facies metamorphic events, respectively. The contents of platinum-group elements (PGE) and Au in chromite separates are relatively high (Os 45, Ir 23, Ru 136, Rh 19, Pt 98, Pd 63, and Au 83 ppb), and significantly enriched (similar to 4x) over whole rock values. Platinum-group minerals are not observed and micrometre-sized inclusions of sulfide minerals (chalcopyrite and pentlandite) in relict chromite are rare. However, comparison of mineral proportions in the separated chromite and whole rock shows that the precious metals are hosted predominantly in the relict igneous chromite grains, rather than the secondary chromian spinel and primary and secondary Mg-rich silicates. The major element composition and average chondrite-normalized PGE pattern of the separated chromite correspond to S-poor stratiform chromitite. We suggest that the precious metals accumulated with chromite during crystallization of a S-poor magma, and were not remobilized in the relict chromite during the subsequent high grade metamorphism.

The effect of electrical discharges without thermic effect and of energy field on Meloidogyne incognita Rara 1 larvae elimination in weir water was tested. on an average, 63,22% of larvae were killed by electrical discharges, in comparison with 53,12% of dead larvae in the control (water that received only ammonium sulphate) as an electrolyte. Water exposed to energy fields presented higher percentages of dead larvae (50,01% for electromagnetic field, 43,78% for variable electric field and 40,48% for static electric field) in comparison with control, represented by water without exposition to any energy field and without ammonium sulphate (34,27%).
