Caracterização molecular de Vibrio cholerae O1 sacarose negativa de isolados clínicos e ambiente na Amazônia brasileira

O V.cholerae é um microorganismo autóctone do ambiente aquático e os sorogrupos O1 e O 139 estão ligados a pandemia e epidemia de cólera. Os V.cholerae não O1 e não O139 ou vibrios não aglutinantes (NAGs) estão envolvidos em casos isolados e surtos de diarréia semelhantes à cólera. No decorrer da sétima pandemia houve o surgimento de diversos isolados “El Tor atípicos”. Entre estes se encontra a variante bioquímica do V.cholerae O1 que não fermenta a sacarose no TCBS em 18 a 24 horas que é o tempo de incubação convencional. Neste trabalho foram estudados 138 isolados de V.cholerae O1 e não O1 não fermentador da sacarose no TCBS de procedência clínica e ambiental, obtidos entre 1994 e 1995 na Amazônia Brasileira (Estados do Pará, Amapá e Amazonas). Avaliou-se a fermentação da sacarose no TCBS e em caldo; o perfil de suscetibilidade a oito diferentes antimicrobianos em ágar difusão; a relação clonal entre os V.cholerae O1 e NAG clínicos e ambientais pelo PFGE e a presença de genes de virulência ctxAB e tcpA pela reação em cadeia da polimerase. Observou-se que as amostras de V.cholerae não fermentaram a sacarose em 24 de incubação no ágar TCBS e em caldo, 43% utilizaram a sacarose em 24 horas e 57% a fermentavam tardiamente (tempo superior a 24 horas). Os isolados apresentaram baixo percentual de resistência a antimicrobianos (8,7%) e nenhum caso de multiresistência. Em relação aos genes de virulência, de um modo geral, os isolados de V.cholerae O1 apresentavam o tcpA e o ctxAB. Nos não O1 estes estavam ausentes, com exceção de um isolado clínico não O1 (gene tcpA+). A análise do PFGE revelou pulsotipos distintos entre os O1 e NAGs, embora dois destes últimos tenham apresentado relação clonal com os O1 clínicos. Todos os O1 clínicos apresentaram relação clonal com isolados de referência da sétima pandemia.

Trabalho e cidadania: em direção a uma vinculação enriquecida

A armadilha posta pelo capitalismo para seus críticos, de defender o emprego da força de trabalho pelo capital como um direito, assume atualmente importante especificidade: o retorno histórico da substituição dos homens por máquinas, mediante a automação de base eletrônica, significa a superação do taylorismo-fordismo. Essa forma de produzir significou uma mediocrização do capitalismo quanto ao desenvolvimento das forças produtivas, dado que lastreava a produção no trabalho vivo. Por ter gerado um círculo virtuoso capital/trabalho, com fortalecimento dos sindicatos e elevação de salários, o fim histórico do taylorismo-fordismo é lamentado por muitos. Na verdade, o capitalismo voltou a ser brilhante quanto ao desenvolvimento das forças produtivas, o que tenderá a marcar de forma cada vez mais nítida sua mediocridade como forma social. Será então possível (e necessário) superar a vinculação empobrecida entre trabalho e cidadania, típica do fordismo, em direção a uma vinculação enriquecida entre os dois conceitos.

Análise de investimento em confinamento bovino no centro-oeste brasileiro: um estudo de caso.

This study analyzed the economic viability of an investment in feedlot cattle on a farm in the midsize state of Goias. The research identified that different thematic studies whose interests have focused mainly on cost analysis and profitability punctual. Differently, this study used the approaches of the Discounted Cash Flow (DCF) and the Real Options Theory (ROT). The first used the projected cash flow for 10 years and a discount rate determined by CAPM at 8% p.a. for containment of heads 400. The second was modeled by the binomial model of Cox, Ross and Rubinstein (1979) incorporating the option of waiting. This methodology has not been employed in Brazilian cattle industry. The search results pointed to the economic viability of the project when considered possible scenarios for the different price ranges of the ox that state bushel. In addition, the TOR proved to be a more robust tool for investment analysis, by incorporating the flexibility of farmers to wait for the right time to make the confinement.

A Closer Look at the Factors that Affect Misdemeanor Offenders

This study examines the common belief that misdemeanor offences are usually committed by individuals from lower socio-economic classes. 1 suggest that this is a misconception and that individuals from all classes commit misdemeanors. The data are from the Monitoring the Future: A Continuing Study of American Youth (12thGrade Survey), 2000-2008 (University of Michigan. Institute for Social Research Survey Research Center). I will focus on 12th grade students from the years 2000 to 2008. For the purposes of this study, a misdemeanor is less severe than a felony and includes such crimes as disorderly conduct, shoplifting, public drunkenness, or minor assault. In addition, conviction for a misdemeanor usually results in a fine or imprisonment in a jail for less than a year. I will examine evidence tor the common belief about the characteristics of misdemeanor offenders and explore other influences on those who commit misdemeanors. This research shows that family relationships, the importance of religion to the respondent, and race have an effect on whether an individual commits a misdemeanor. The results of this study »"~'-10'."""'~ that other factors, besides social class, may be important for understanding misdemeanor activity.

Molecular determinants of caste differentiation in the highly eusocial honeybee Apis mellifera

Abstract Background In honeybees, differential feeding of female larvae promotes the occurrence of two different phenotypes, a queen and a worker, from identical genotypes, through incremental alterations, which affect general growth, and character state alterations that result in the presence or absence of specific structures. Although previous studies revealed a link between incremental alterations and differential expression of physiometabolic genes, the molecular changes accompanying character state alterations remain unknown. Results By using cDNA microarray analyses of >6,000 Apis mellifera ESTs, we found 240 differentially expressed genes (DEGs) between developing queens and workers. Many genes recorded as up-regulated in prospective workers appear to be unique to A. mellifera, suggesting that the workers' developmental pathway involves the participation of novel genes. Workers up-regulate more developmental genes than queens, whereas queens up-regulate a greater proportion of physiometabolic genes, including genes coding for metabolic enzymes and genes whose products are known to regulate the rate of mass-transforming processes and the general growth of the organism (e.g., tor). Many DEGs are likely to be involved in processes favoring the development of caste-biased structures, like brain, legs and ovaries, as well as genes that code for cytoskeleton constituents. Treatment of developing worker larvae with juvenile hormone (JH) revealed 52 JH responsive genes, specifically during the critical period of caste development. Using Gibbs sampling and Expectation Maximization algorithms, we discovered eight overrepresented cis-elements from four gene groups. Graph theory and complex networks concepts were adopted to attain powerful graphical representations of the interrelation between cis-elements and genes and objectively quantify the degree of relationship between these entities. Conclusion We suggest that clusters of functionally related DEGs are co-regulated during caste development in honeybees. This network of interactions is activated by nutrition-driven stimuli in early larval stages. Our data are consistent with the hypothesis that JH is a key component of the developmental determination of queen-like characters. Finally, we propose a conceptual model of caste differentiation in A. mellifera based on gene-regulatory networks.

Pattern recognition analysis on heavy ion reaction data

One of the problems in the analysis of nucleus-nucleus collisions is to get information on the value of the impact parameter b. This work consists in the application of pattern recognition techniques aimed at associating values of b to groups of events. To this end, a support vec- tor machine (SVM) classifier is adopted to analyze multifragmentation reactions. This method allows to backtracing the values of b through a particular multidimensional analysis. The SVM classification con- sists of two main phase. In the first one, known as training phase, the classifier learns to discriminate the events that are generated by two different model:Classical Molecular Dynamics (CMD) and Heavy- Ion Phase-Space Exploration (HIPSE) for the reaction: 58Ni +48 Ca at 25 AMeV. To check the classification of events in the second one, known as test phase, what has been learned is tested on new events generated by the same models. These new results have been com- pared to the ones obtained through others techniques of backtracing the impact parameter. Our tests show that, following this approach, the central collisions and peripheral collisions, for the CMD events, are always better classified with respect to the classification by the others techniques of backtracing. We have finally performed the SVM classification on the experimental data measured by NUCL-EX col- laboration with CHIMERA apparatus for the previous reaction.

Competitività in sostenibilità urbana e territoriale. L’Emilia Romagna, regione d’Europa

The thesis in Urban and Regional Geography titled “URBAN AND TERRITORIAL COMPETITIVENESS IN SUSTAINABILITY. EMILIA-ROMAGNA, REGION OF EUROPE” is divided into two sections. Section one is additionally composed by two chapters (chap. 1 and 2) and deals with theoretical and gnosiological issues. Section two, of two more chapters (chap. 3 and 4), provides practical contributions: these issues give explanatory patterns to interpret the performances of emiliano-romagnoli urban systems. Chapter one is an introductory chapter. It analyzes globalization that involves a larger and larger number of cities, rich or poor. It also considers the so called “digital divide” either as one of the major phenomena of this unhomogeneous development or as an interesting gnosiological and practical challenge of geography. Globalization is now involving all the cities, large or small, but the small ones have higher risks of exclusion: it depends on their more fragile socio-economic, cultural, and environmental urban structure. That’s why European Union (chapter two) promotes policies and endows politics to sustain cities, because urban systems are the basis for the territorial development. So, European, national and local Institutions are firmly interested in promoting urban and local interventions and projects. Section two deals with economic-geography methods, which consists on collecting indicators and the benchmarking methodology. It also specifically analyzes the urban systems of Emilia-Romagna. Consequences of the globalization on the cities are interpreted with a study of their local resources, intended as potentials for their development. The STeMA approach, proposed by Professor Maria Prezioso (University of Roma, “Tor Vergata”) and used by the ESPON (European Spatial Program Observation Network) project, describes the main “determinants” of the territorial and urban development. These are easily comparable to one another (similar or better performing). This approach achieves two goals. On one hand, it is possible to analyze every urban system in its all main characteristics and to preserve its historical and cultural factors. On another hand, each city is “knowable” and “understandable” by all scholars, as it is objectively comparable. So, urban planners can propose specific “multi-level” and “multi-varied” programs of governance. These will face globalization by exalting local empowerment.

Mediterranean brachiopods: morphological, ecological and phylogenetic aspects

The Brachiopoda of the Marine Protected Area “Secche di Tor Paterno”, Central Tyrrhenian Sea, have been investigated in order to give a first glance of the diversity of the brachiopods of this area and provide a new report on the Mediterranean Brachiopod fauna. Four species were reported: Novocrania anomala (Müller, 1776), Megathiris detruncata (Gmelin, 1790), Joania cordata (Risso,1826) and Argyrotheca cuneata (Risso,1826). For all the four species a morphological analysis was carried out. For the two most abundant species, J.cordata and A. cuneata, a morphometric study, based on thickness/width and length/width scattergrams, was carried out, in order to investigate their variability. Size-frequency distributions relative to the three dimensions of the shell were also computed, aimed at a evaluation of population dynamics of these two species. The results showed that, for both species, the parameters which most determine the rise of the shell during the growth of animal are width and length and that frequency distributions are mainly bi- or plurymodal and that they are difficult to interpret, as reported by other studies. Analysis of drill holes found on the shell of some specimens of the two same species revealed a predatory origin and that three different predators are responsible for them. Partial sequences of two different genetic markers, the Internal Transcribed Spacer 1 (ITS1) and the cytochrome oxidase subunit 1 (COI), were used to investigate the phylogenetic relationship between two populations of the eurybathic brachiopod species Gryphus vitreus (Born,1778) across the strait of Gibraltar. This represents the first genetic population study on brachiopods. Results from AMOVA and Bayesian analysis performed on 31 specimens highlighted no genetic differentiation indicating a likely panmixia, dispite the lecitotrophic development of the species.

Functional equations of polylogarithms in motivic cohomology

For an infinite field F, we study the integral relationship between the Bloch group B_2(F) and the higher Chow group CH^2(F,3) by proving some relations corresponding to the functional equations of the dilogarithm. As a second result, the groups involved in Suslin’s exact sequence 0 → Tor^1(F^× ,F^×)∼ → CH^2(F,3) → B_2(F) → 0 are identified with homology groups of the cycle complex Z^2(F,•) computing Bloch’s higher Chow groups. Using these results, we give explicit cycles in motivic cohomology generating the integral motivic cohomology groups of some specific number fields and determine whether a given cycle in the Chow group already lives in one of the other groups of Suslin’s sequence. In principle, this enables us to find a presentation of the codimension two Chow group of an arbitrary number field. Finally, we also prove some relations in the higher Chow groups of codimension three modulo 2-torsion coming from relations in the higher Bloch group B_3(F) modulo 2-torsion. Further, we can prove a series of relations in CH^ 3(Q(zeta_p),5) for a primitive pth root of unity zeta_p.
