O circuito espacial de produção e os círculos de cooperação da soja no Maranhão no período técnico-científico informacional

The study in screen it has as objective the understanding of the space circuit of production and the circles of cooperation of the soy that if develop in the Maranhão in the technician-scientific-informational period. Characterized for the material and incorporeal flows if they develop in the Maranhão, from the moment where it had a process of integration of the maranhense territory while peripheral space of the capitalist dynamics, that if gave through the politics of regional integration created by the State, but when it had a process of selective modernization, also partial and conservative of the agriculture, that made possible the significant increase of the production and reproduction of the capital. The study sample that with the advent of the soy, had a concentration of the production techniques, mainly in the agricultural region of Balsas, due to bigger it offers of lands, time of implantation of the culture, technique accumulated in the production, whereas in the agricultural region of Chapadinha, these indices still are without representation. Moreover, the intensification of the agricultural credit, the agrarian politics and tax incentives are elements that have propitiated increase of the production of the soy. The development of the space circuit and circles of cooperation of the soy, a side, create new forces politics in the Maranhão that can result in the creation of a new state, the other, are responsible, for the elimination of part of the subsistence agriculture, producing social problems as, agrarian concentration and unemployment. The study it still evidences the appropriation of the place for a small number of companies that has generated, beyond an intense concentration of income, an alienation of the territory, in view of that this is used for a strange purpose to the place and the yearning of the population does not stop

Caracterização do gene da proteína capsidial de dois isolados, patologicamente distintos e sorologicamente semelhantes, do Grapevine virus B em videiras no Estado de São Paulo

No presente trabalho, descreve-se a caracterização do gene codificador da proteína capsidial de dois isolados sintomatologicamente distintos do Grapevine virus B (GVB). Para isto, RNA totais foram extraídos de folhas e pecíolos de videiras (Vitis spp.) infetadas, cultivares Rubi (GVB-C SP) e Itália (GVB-I SP) e utilizados para amplificar, por RT/PCR, um fragmento entre as posições 6425 e 7118 (694 nucleotídeos, nt) do RNA do GVB (GenBank, acesso X75448). O fragmento obtido inclui o gene da proteína capsidial (594 nt) codificando 197 aminoácidos com massa molecular estimada em aproximadamente 21.600 Da. A seqüência do GVB-C SP apresentou maior similaridade de nucleotídeos e aminoácidos deduzidos com o isolado italiano (acesso X75448), enquanto que o GVB-I SP foi mais similar a um outro isolado brasileiro do GVB descrito no Rio Grande do Sul (GVB BR1, acesso AF438410). Os dois isolados paulistas do GVB podem ser diferenciados por digestão com a enzima de restrição EcoRI, uma vez que há um sítio interno no GVB-C SP que está ausente no isolado GVB-I SP.

Antiretroviral resistance mutations in human immunodeficiency virus type 1 infected patients enrolled in genotype testing at the Central Public Health Laboratory, São Paulo, Brazil: preliminary results

Antiretroviral resistance mutations (ARM) are one of the major obstacles for pharmacological human immunodeficiency virus (HIV) suppression. Plasma HIV-1 RNA from 306 patients on antiretroviral therapy with virological failure was analyzed, most of them (60%) exposed to three or more regimens, and 28% of them have started therapy before 1997. The most common regimens in use at the time of genotype testing were AZT/3TC/nelfinavir, 3TC/D4T/nelfinavir and AZT/3TC/efavirenz. The majority of ARM occurred at protease (PR) gene at residue L90 (41%) and V82 (25%); at reverse transcriptase (RT) gene, mutations at residue M184 (V/I) were observed in 64%. One or more thymidine analogue mutations were detected in 73%. The number of ARM at PR gene increased from a mean of four mutations per patient who showed virological failure at the first ARV regimens to six mutations per patient exposed to six or more regimens; similar trend in RT was also observed. No differences in ARM at principal codon to the three drug classes for HIV-1 clades B or F were observed, but some polymorphisms in secondary codons showed significant differences. Strategies to improve the cost effectiveness of drug therapy and to optimize the sequencing and the rescue therapy are the major health priorities.

Anatomia e uso da madeira de duas variedades de Sclerolobium paniculatum Vog. do sul do Maranhão, Brasil

O presente estudo traz informações sobre a utilização da madeira de duas variedades de Sclerolobium paniculatum (var. subvelutinum e rubiginosum) em propriedades rurais do sul do Maranhão, a análise anatômica do lenho e a correlação destas características com o uso da madeira. Foram realizadas entrevistas com 17 agricultores residentes na zona rural dessa região, com a finalidade de se conhecer a utilização destas variedades nas propriedades rurais. As variedades subvelutinum Benth. e rubiginosum (Mart. ex Tul. ) Benth. são conhecidas na região como cachamorra-preta e cachamorra-branca, respectivamente, sendo a primeira mais utilizada na confecção de cercados. Para o estudo anatômico do lenho, foram coletados discos à altura do peito de três indivíduos de cada variedade e, destes, obtidas amostras do cerne, na região de transição com o alburno. As amostras foram processadas de acordo com a metodologia usual para anatomia de madeira. Houve diferença estatística significativa (p<0,05) para seis parâmetros anatômicos entre as duas variedades. A utilização diferencial das variedades pode ser decorrente, principalmente, das características das fibras e dos elementos de vasos. Sugere-se que sejam realizados estudos que abordem variações climáticas e características do solo para melhor entendimento das diferenças anatômicas quantitativas encontradas no lenho das variedades.

Modelagem gravimétrica da Bacia de Taubaté-vale do Rio Paraíba do Sul, leste do estado de São Paulo

This paper presents the gravity survey refinement of the Paraíba do Sul river valley, east region of São Paulo state, by acquisition of 646 gravity stations. Further than the traditional Free-Air and Bouguer corrections, it was necessary to apply the Terrain Correction due the proximity of the Mantiqueira and Mar mountain ranges. An enhanced understanding of Taubaté Basin structural framework was the main objetive of this work. As result, we present the Bouguer Gravity Map of the east region of São Paulo State and the Residual Bouguer Gravity Map generated by Upward Continuation and High-pass filtering. The 2D Gravity Modeling was applied in 4 sections, using bi-dimensional models for the bodies that produced the anomalies (Talwani Method). After integrating the gravity data with the interpretation of 11 seismic sections, it was possible to delineate the Taubate Basin structural framework, which shows an utmost sedimentary thickness of 800 m in the depocenters. It was also interpreted an ultramaphic alkaline plug in the subsurface of Caçapava city.

Isolation of Mycobacterium gordonae from poultry slaughterhouse water in São Paulo State, Brazil

Water samples (24 untreated water, 12 treated water and 24 served water) used in different stages of the slaughter process were examined to identify a possible source of pathogenic mycobacteria. The isolates were identified based on microscopy, morphological and biochemical features, mycolic acid analysis and molecular method - PCR-restriction-enzyme analysis. Eighteen mycobacterial strains were isolated from 60 water samples: 11 from untreated water, 5 from treated water and 2 from served water. All mycobacteria isolated were identified as Mycobacterium gordonae and showed the following PRA genotypes: III (27.8%), IV (38.9%) and V (33.3%).

Occurrence of Actinobacillus actinomycetemcomitans in patients with chronic periodontitis, aggressive periodontitis, healthy subjects and children with gingivitis in two cities of the state of São Paulo, Brazil

The aim of this study was to determine the frequency of isolation of Actinobacillus actinomycetemcomitans (Aa) in 100 patients with chronic periodontitis, 14 patients with aggressive periodontitis, 142 pre-school children with gingivitis and 134 periodontally healthy subjects. Samples of subgingival plaque were taken using sterilized paper points introduced into periodontal pockets or gingival crevice for 60 seconds and inoculated on TSBV agar, which was incubated under anaerobiosis at 37°C, for 4 days. Microbial identification was performed through biochemical methods and morphocellular and morphocolonial analysis. Aa was detected in 40.3% of healthy subjects, 68% of patients with chronic periodontitis, 92.86% of patients with aggressive periodontitis and 40.14% of children with gingivitis. The rate of recovery of Aa in the tested human groups proved to be higher than previously reported and in agreement with participation of this facultative anaerobe as a member of native microbiota of the periodontium and its relation with aggressive and chronic periodontitis in Brazil.

Integrated quality assessment of sediments from harbour areas in Santos-São Vicente Estuarine System, Southern Brazil

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems. © 2013 Elsevier Ltd.
