Cervical cancer is a major source of illness and death among women worldwide and genital infection with oncogenic human papillomavirus (HPV) its principal cause. There is evidence of the influence of the male factor in the development of cervical neoplasia. Nevertheless, the pathogenic processes of HPV in men are still poorly understood. It has been observed that different HPV types can be found among couples. The objective of the present study was to investigate HPV infections in female patients (n = 60 females/group) as well as in their sexual partners and to identify the concordance of HPV genotypes among them. By using the polymerase chain reaction, we detected a 95% prevalence of HPV DNA in women with cervical intraepithelial neoplasia (CIN) compared to 18.3% in women with normal cervical epithelium, with a statistically significant difference (P < 0.001). The HPV DNA prevalence was 50% in male partners of women with CIN and 16.6% in partners of healthy women. In the control group (healthy women), only 9 couples were simultaneously infected with HPV, and only 22.2% of them had the same virus type, showing a weak agreement rate (kappa index = 0.2). Finally, we observed that HPV DNA was present in both partners in 30 couples if the women had CIN, and among them, 53.3% shared the same HPV type, showing moderate agreement, with a kappa index of 0.5. This finding supports the idea of circulation and recirculation of HPV among couples, perpetuating HPV in the sexually active population, rather than true recurrences of latent infections.

O ecossistema aqutico o habitat de mexilhes (Perna perna), animais filtradores que refletem a qualidade ambiental atravs de anlise microbiolgica de sua carne. No presente trabalho avaliou-se a presena de patgenos emergentes (Aeromonas hydrophila e Plesiomonas shigelloides), em mexilhes in natura e pr-cozidos coletados por pescadores da Estao Experimental de Cultivo de Mexilhes situada em Jurujuba, Niteri, Rio de Janeiro. Foram analisadas 86 amostras de mexilhes (43 in natura e 43 pr-cozidos) as quais foram submetidas a enriquecimento em gua Peptonada Alcalina (APA) acrescida de 1 e 3% de Cloreto de Sdio (NaCl) e em soluo Salina de Butterfield, incubadas a 37C por 24 horas. Em seguida, foram semeadas em gar Seletivo para Pseudomonas-Aeromonas (GSP), gar Tiossulfato Citrato Bile Sacarose (TCBS) e gar Inositol Bile Verde Brilhante (IBB). A anlise geral dos resultados permitiu a identificao de Areomonas spp e Plesiomonas shigelloides em 86% das amostras de mexilhes in natura e pr-cozidas avaliadas. A posterior caracterizao bioqumica permitiu a identificao das espcies Aeromonas media (37,10%), A. hydrophila (15,50%), A. caviae (14,80%), A. veronii biogrupo veronii (11,60%), Aeromonas sp. (7,36%), A. sobria (4,20%), A. trota (4,20%), A. schubertii (1,31%), A. jandaei (1,31%), A. veronii biogrupo sobria (0,52%) e Plesiomonas shigelloides (2,10%). A relevncia epidemiolgica desses microrganismos em casos de gastrenterite humana, aps consumo de mexilhes crus ou parcialmente cozidos, revela a importncia de alertar as autoridades de Sade Pblica no Brasil, sobre a presena desses patgenos na cadeia alimentar e seus riscos para a sade humana.

A anlise microbiolgica dos mexilhes reflete a qualidade do habitat aqutico, pois estes animais podem reter em seus organismos diversos patgenos, dentre os quais aqueles pertencentes famlia Vibrionaceae. No presente estudo foi avaliada a presena de Vibrio spp. em mexilhes (in natura e pr-cozidos), comercializados na Estao Experimental de Cultivo de Mexilhes, situada em Jurujuba, Niteri, Rio de Janeiro. Foram avaliadas 86 amostras, tomando como procedimento, o enriquecimento em gua Peptonada Alcalina (APA) adicionada de 1 e 3% de NaCl, isolamento em Agar Tiossulfato Citrato Bile Sacarose (TCBS) e confirmao das colnias tpicas por anlise bioqumica. Dentre as 12 espcies de Vibrio identificadas destacaram-se como de maior prevalncia as espcies Vibrio alginolyticus, V. cholerae no-O1, V. parahaemolyticus, V. carchariae e Vibrio vulnificus. A relevncia epidemiolgica destes patgenos associada a casos de gastrenterite humana aps consumo de mexilhes crus ou parcialmente cozidos, refora a importncia de alertar as autoridades de Vigilncia Sanitria sobre sua presena na cadeia alimentar e seus riscos para a Sade Pblica.

Coffee is one of the most appreciated drinks in the world. Coffee ground is obtained from the fruit of a small plant that belongs to the genus Coffea. Coffea arabica and Coffea canephora robusta are the two most commercially important species. They are more commonly known as arabica and robusta, respectively. Two-thirds of Coffea arabica plants are grown in South and Central America, and Eastern Africa - the place of origin for this coffee species. Contamination by microorganisms has been a major matter affecting coffee quality in Brazil, mainly due to the harvesting method adopted. Brazilian harvests are based on fruits collected from the ground mixed with those that fall on collection cloths. As the Bacillus cereus bacterium frequently uses the soil as its environmental reservoir, it is easily capable of becoming a contaminant. This study aimed to evaluate the contamination and potential of B. cereus enterotoxin genes encoding the HBL and NHE complexes, which were observed in strains of ground and roasted coffee samples sold in Rio de Janeiro. The PCR (Polymerase Chain Reaction) results revealed high potential of enterotoxin production in the samples. The method described by Speck (1984) was used for the isolation of contaminants. The investigation of the potential production of enterotoxins through isolates of the microorganism was performed using the B. cereus enterotoxin Reverse Passive Latex Agglutination test-kit (BCET-RPLA, Oxoid), according to the manufacturer's instructions. The potential of enterotoxin production was investigated using polymerase chain reaction (PCR) methods for hblA, hblD and hblC genes (encoding hemolysin HBL) and for nheA, nheB and nheC genes (encoding non-hemolytic enterotoxin - NHE). Of all the 17 strains, 100% were positive for at least 1 enterotoxin gene; 52.9% (9/17) were positive for the 3 genes encoding the HBL complex; 35.3% (6/17) were positive for the three NHE encoding genes; and 29.4% (5/17) were positive for all enterotoxic genes.

Ce mmoire interroge lhistoire, larticulation pratique et les effets de ce que lon appelle actuellement au Brsil lurbanisation intgratrice, un type dintervention tatique dans les favelas (bidonvilles) de Rio de Janeiro. Il sagit dune nime tentative de rgler le problme de la favela, consistant en lurbanisation de son territoire (insertion dinfrastructure publique, consolidation du cadre bti) et la lgalisation de son statut et de ses pratiques (octroi de droits de proprit foncire et insertion de rglementation publique). Officiellement, cest une manire de mettre fin lexclusion dont les populations faveladas sont victimes depuis lapparition des favelas Rio. Lanalyse est faite partir de ltude du PAC-Favelas, un programme du gouvernement fdral lanc en 2008, et son application dans la favela Rocinha. Il est propos de considrer lurbanisation intgratrice en tant que dispositif scuritaire ou biopolitique, cest--dire en tant quappareil de gouvernement de la population locale. travers le projet, on planifie de formaliser les conduites, daccrotre la circulation des ressources, de transformer les perceptions des rsidents, de contenir les excs et les risques associs la favela et de tendre vers la prise en charge entirement planifie en un mot, dassurer le passage vers lintervention permanente. Concrtement, cela revient pour ltat procder une slection, par des moyens lgitims ou indirects (le plan, la loi, le march), des individus et des pratiques dsormais admissibles sur le territoire. Lespace se rarfie, le contrle augmente et les prix montent : ne peut demeurer que celui qui a dj atteint un certain niveau de stabilit, relguant les plus prcaires devoir progressivement quitter le territoire. Urbaniser la Rocinha, cest un peu forcer son embourgeoisement en la rendant enfin scurise, civilise et rentable.

Ce projet de matrise porte sur linteraction entre les acteurs locaux lis la musique populaire et ladministration publique dans le cadre du projet public-priv de ramnagement du port de Rio de Janeiro intitul Porto Maravilha. Le travail de recherche sest ax sur lide que cette interaction serait essentiellement fonde sur la faon dont la culture est comprise et utilise comme ressource capable dajouter de la valeur lespace urbain, diffrencier les groupes entre eux et apporter une sustentation au processus dautonomisation et de lgitimation des acteurs. De nouveaux paradigmes urbanistiques, tel celui de ville crative (Landry, 2005), proposent dintgrer la culture locale dans llaboration et lexcution des projets avec la participation dartistes qui sont perus comme une source de crativit fondamentale pour rendre la ville plus comptitive dans un monde devenu de plus en plus urbain. Dans cette veine, le projet Porto Maravilha sinspire franchement des cas de succs de rnovation urbaine crative, stimulant la culture locale et idalisant le port de Rio comme une nouvelle carte postale du Brsil. En partant de la constatation que les acteurs sociaux locaux identifient le potentiel de leurs activits culturelles comme une ressource importante dans ce contexte, nous analysons tout autant les stratgies et les discours labors que les ressources dont ils disposent afin daffirmer leur agentivit. Au-del de laction intentionnelle, nous effectuons galement des analyses de leurs pratiques culturelles au quotidien en recherchant les lments qui les constituent. Nous questionnons, par ailleurs, la manire avec laquelle les administrateurs du projet comprennent ces activits musicales et comment ils grent les demandes sociales et les contributions cratives de ces groupes.

One of the main stated objectives of the Favela Bairro program was to allow squatter settlements to become part of the formal city. The focus of the study is to assess how different project solutions in the Favela Bairro program have used urban design tools to achieve this objective. A subsequent question concerns the extent to which urban design factors helped to improve the social integration of the settlements, and specifically to overcome poverty and exclusion conditions.This bring us to a another group of problems related to indicators to measure the attainment of these objectives from four perspectives: Spatial, Social, Economical and Political (citizenship and participation)This analysis highlights the major difficulties confronted by the design teams, and allows pinpointing the positive and negative impacts of the interventions on the communities and the city
