Abstract: Background: Prostate cancer is the second most common type of cancer in man and the second in cancer-specific deaths in this population in the world. Most of the causes of death related to prostate cancer are due to its distant metastases, with the most common sites being: skeleton, distant lymph nodes, liver and lung. Renal metastasis is rare, and studies suggest infiltration due to arterial microembolization of the tumor. A key point in this scenario is the clinical suspicion of differential diagnoses, to offer the patient an effective therapy in such a specific case. Aim: To report a case of a patient with prostate cancer undergoing partial nephrectomy whose histopathological report revealed a metastatic lesion of that primary site. Case Presentation: 74 years old man, referred in May 2015 due to high PSA level and lumbago. PSA 323.11 ng/dl, rectal examination cT3a; biopsy was performed and histopathological study reported bilateral prostate adenocarcinoma, Gleason’s score 8 (4 + 4). Patient’s staging showed multiple secondary implants on skeletal scintigraphy. Tomography revealed solid exophytic lesion in the lower pole of the right kidney (4.7 × 3.6 cm); prostate without cleavage planes with seminal vesicles and pelvic node enlargement. Hormone therapy was initiated, PSA levels dropped to 9.51 ng/dl and total testosterone < 50 ng/dl. Partial nephrectomy was planned, initially by laparoscopy, but converted to laparotomy in December 2015. Procedure lasting 3 hours, minimal blood loss, no perioperative complications, discharged on the 3rd postoperative day. Histopathological report described undifferentiated malignant neoplasm, requiring immunohistochemistry that confirmed prostate adenocarcinoma. Patient remains hormone therapy, with no progression of the disease so far. Conclusion: Given the rarity of these cases, it is not possible to presume that nephrectomy enhances the survival rates. However, we observed that partial nephrectomy was a good choice for our patient, being the first case described in the literature. More reports should be available and studies with higher levels of evidence should be conducted to assist us in patient orientation and decision making.

Abstract: Este estudo objetivou avaliar a qualidade de leite cru em trinta amostras colhidas de tanques de expans o no estado de Goiás, num volume de 1.000 mL. Para tanto, realizou-se contagem bacteriana total (CBT) por citometria de fluxo, bem como se procedeu a pesquisas de resíduos de antimicrobianos pelo kit Delvotest SP e de fraude por adi o de água oxigenada, formol, bicarbonato de sódio e hidróxido de sódio. Em 100% das amostras notou-se ausência de resíduos de antimicrobianos. Além disso, os testes físico-químicos n o indicaram a presen a de água oxigenada, formol, bicarbonato de sódio e hidróxido de sódio. Do total dos tanques de expans o, 30% (9/30) apresentaram CBT >106 UFC/mL, em 46,67% (14/30) a CBT estava entre 105 e 106 UFC/mL e em 23,33% (7/30) havia CBT <105 UFC/mL. As médias observadas foram CBT de 9,2 x 106 UFC/mL, CBT de 4,5 x 105 UFC/mL e CBT de 5,1 x 104 UFC/mL, respectivamente. Dos tanques de expans o com CBT >106 UFC/mL, 100% eram de uso coletivo e mostraram valores de CBT significativamente maiores (P<0,05). Medidas de educa o e treinamento quanto aos procedimentos de obten o higiênica do leite, à higiene dos equipamentos de ordenha, à correta implanta o e execu o de programa de controle de mastite e do sistema de refrigera o da matéria-prima pós-ordenha precisam ser adotadas visando à melhoria da qualidade do leite cru. Tais medidas beneficiam tanto a indústria, concorrendo para rendimento da matéria-prima, quanto o produtor rural, pela possibilidade de remunera o mais vantajosa, por empresas do setor lácteo que adotam o sistema de pagamento por qualidade do leite. Favorecem o comércio, pelo aumento da vida de prateleira dos derivados lácteos, e o consumidor, que adquire produto de mais qualidade. PALAVRAS-CHAVES: Leite cru, qualidade, resíduos, UFC. This research aimed to evaluated the raw milk quality in samples obtained from bulk tanks in the Goiás State. Thirty raw milk samples of 1000 mL were harvest. It was performed the following analyses: total bacterial count (TBC) by Flow Citometry, search for the presence of residues of antimicrobial agents by the Delvotest SP kit and investigation for the fraud by adding to milk the following substances: hydrogen peroxide, formaldehyde, sodium bicarbonate and sodium hydroxide. It was not found any residues of antimicrobial agents in all (100%) samples. Physicochemical test also showed the absence of hydrogen peroxide, formaldehyde, sodium bicarbonate and sodium hydroxide in milk. About TBC, it was observed that 30% (9/30) of bulk tanks showed TBC>106 CFU/mL, in 46.67% (14/30) the TBC

Abstract: The objective of this study was to evaluate the effect of bronopol chemical in contrast to azidiol in the total bacterial counting (TBC) in raw milk samples submitted the different temperatures of storage. Four bands of samples storage temperature had been evaluated: T1 – 1.8 the 4.2 oC; T2 – 6.4 the 8.3oC; T3 – 12.1 the 14.5oC; and T4 – 24 the 25.5oC in three groups: Group 1 – control without chemical; Group 2 – liquid azidiol added of bromofenol blue; Group 3 – Bronopol . The samples were analyzed during ten consecutive days, starting 24h after sampling. After analyzes by the flow citometry, have been considered raw milk samples of 14 expansion tanks that were divided in two levels of milk contamination: <105 and >106 CFU/mL. The bronopol effect was influenced by the raw milk contamination level. The Bronopol has bacteriostatic effect in milk samples with TBC below of 105 CFU/mL and bactericidal in samples with TBC above of 106 CFU/mL. The TBC gotten in raw milk samples conserved with bronopol was lower to that one gotten in the samples with azidiol. The bronopol effect on the TBC was influenced by the temperature and by the storage time of the sample. The Bronopol bactericidal effect becomes impracticable its use in raw milk samples destined the TBC. The azidiol efficiency in the raw milk sample destined the CBT as bacteriostatic agent was dependent of the lesser storage temperature of the sample, independent of the initial contamination level. The raw milk sample destined the CBT can be analyzed in up to one week after harvested if the same one will be added of azidiol and kept under refrigeration in temperature between 1oC and 4 oC. KEY WORDS: Azidiol, bronopol, bacterial counting, raw milk, time, temperature. O presente estudo objetivou avaliar o efeito do conservante bronopol em contraste ao azidiol na contagem bacteriana total (CBT) em amostras de leite cru submetidas a diferentes temperaturas de armazenamento. Avaliaram-se quatro faixas de temperatura de armazenamento de amostras: T1 – 1,8 a 4,2 oC; T2 – 6,4 a 8,3oC; T3 – 12,1 a 14,5oC; e T4 – 24 a 25,5oC, em três grupos: Grupo 1 – controle sem conservante; Grupo 2 – azidiol líquido + corante azul de bromofenol; Grupo 3 – bronopol . As amostras foram analisadas durante dez dias consecutivos, iniciando 24 horas após colhidas. Após análise por citometria de fluxo pelo equipamento BactoScan FC, consideraram-se amostras de leite cru de quatorze tanques de expans o divididas em dois níveis de contamina o do leite: <105 e >106 UFC/mL. Houve efeito do conservante bronopol pelo nível de contamina

Signótica , 2012, DOI: 10.5216/sig.v24i2.14024
Abstract: Diglossia, empréstimo e codeswitching s o considerados como algumas das principais amea as para as línguas indígenas quando em contato com línguas n o indígenas e de maior prestígio, geralmente a língua oficial da na o. Embora, por vezes, invisíveis aos seus falantes, os empréstimos e codeswitchings podem permear a língua indígena a tal ponto que seja quase impossível distinguir qual delas é a língua base. Este artigo trata destes temas junto à língua Xerente Akwén, povo indígena altamente bilíngüe. O Xerente-Akwén é uma língua indígena da família Jê, falada por 3.600 pessoas no estado de Tocantins, Brasil. Os dados foram coletados durante viagens a campo no ano de 2010. Observa es, entrevistas pessoais e questionários foram recentemente descritos, analisados e mensurados através de um modelo estatístico. Os resultados mostram que há um grande número de empréstimos e codeswitchings feitos principalmente pelos mais jovens causando uma situa o de diglossia. A obsolescência da língua indígena permanece uma quest o em aberto a ser respondida.
Desafios logísticos às redes de negócios no Brasil: o que podem as parcerias público-privadas (PPPs)? Logistical challenges to business networks in Brazil: what can public-private partnerships (PPPs) do?
Arlan Mendes Mesquita,Ricardo S. Martins
Revista de Administra??o Pública , 2008, DOI: 10.1590/s0034-76122008000400006
Abstract: Este artigo discute a distribui o regional dos investimentos prioritários para parcerias público-privadas (PPPs), tendo por base as condi es logísticas para forma o de redes de negócios nas regi es e a perspectiva de estratégia de redu o das desigualdades regionais, e como foco os sistemas de transporte. Considerando-se os aspectos positivos da regulamenta o e o fato de n o ter o objetivo de promover uma descentraliza o da riqueza nacional, conclui-se que além de n o se poder esperar das PPPs o efeito de redu o das desigualdades regionais no Brasil - uma distor o com repercuss es extremamente negativas para o desenvolvimento brasileiro - é bastante possível que o efeito seja no sentido de refor ar as desigualdades. This article investigates the regional distribution of priority investments of public-private partnerships (PPP), based on the logistic conditions for business-oriented networks in the regions and the strategic perspective of reducing regional inequalities, with a focus on transportation systems. Taking into consideration the positive aspects of regulation and the fact that it does not have as its objective the promotion of decentralization of the national wealth, the article concludes that PPPs are not supposed to reduce regional inequalities in Brazil, a distortion with extremely negative repercussions for Brazilian development. Besides, the article indicates that it is even possible for PPPs to have an adverse effect, strengthening inequalities.

Sociologia da governan?a francesa das águas
Martins, Rodrigo Constante;
Revista Brasileira de Ciências Sociais , 2008, DOI: 10.1590/S0102-69092008000200007
Abstract: access to water resources has gained extensive scientific and political relevance over the last three decades. the french modern experience has become a reference point for the institutionalization of new management practices. in brazil, this experience provided a basis for establishing not only new state management apparatuses, but also the water resources national policy itself. this article seeks to examine relevant social disputes concerning water management technocracy over the establishing period of the new management apparatus. thus, we have reviewed the sociopolitical net involving agents, groups, and social institutions towards the definition of a new regulatory frame. this frame has resulted in a symbolic re-designation of the resource (reaching the category of natural capital) and a 'scientification' of politics as a principle for legitimating competence in water governance.
Representa??es sociais, institui??es e conflitos na gest?o de águas em territórios rurais
Martins, Rodrigo Constante;
Sociologias , 2006, DOI: 10.1590/S1517-45222006000100011
Abstract: issues related to the governance of social interests and environmental resources established in rural territories have been highlighted in recent sociological literature. surrounded by the issues of new ruralities, the debate about the makeup of distinct social interests within environmental management and territorial management bodies keeps demanding reflection from social sciences. in order to contribute new subsidies to such debate, this article presents a new sociological research about the territorial and political-institutional conflicts in the management of regional bodies for water policy in the state of s?o paulo (brazil). through a case study made with qualitative techniques for social research, the work discusses how distinct agricultural interests relate to modern tools for environmental pubic regulation - notably the basin committees. the study's general hypothesis is that formal democracy represented by those environmental public regulation bodies cannot stand the fundaments of local structures of political and economic domination.
