Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

LEVANTAMENTO RETROSPECTIVO DOS ATENDIMENTOS DO AMBULATÓRIO DE FISIOTERAPIA DERMATO-FUNCIONAL DA UNIVERSIDADE POTIGUAR

A fisioterapia dermato-funcional é uma área do conhecimento em plena expansão, caracterizada por fornecer serviço nos três níveis de atenção à saúde, tratando diferentes patologiasde âmbito estético e reparador. A Universidade Potiguar (UNP) é uma instituição pioneira no estado do Rio Grande do Norte no serviço de fisioterapia dermato-funcional e oportuniza àpopulação carente o acesso a tratamentos de alto custo, com a utilização de recursos avançados neste segmento. O objetivo deste estudo foi verificar as características da população atendida na Clínica Escola de Fisioterapia Dermato-Funcional da UnP. Trata-se de um estudo descritivo, retrospectivo, no qual, foram analisados os prontuários de 863 pacientes que freqüentaram o serviço de fisioterapia dermato-funcional, de 2000 a 2009. Observou-se uma variação no públicode pacientes que frequentou o serviço, constatando-se que, no ano de 2001, o percentual de homens que procurou o serviço foi de, no máximo, 4,4%, aumentado para 30,27% em 2009.Foram atendidos quase 100 pacientes anualmente, tratando diferentes patologias, em destaque a adiposidade. Os pacientes realizaram, na maioria dos casos, de 01 a 05 sessões, com importante índice de abandono. Esse abandono pode estar relacionado a frequentes interrupções dosatendimentos devido ao período de férias ou mudanças na estrutura curricular semestralmente e isso pode ser considerado uma das limitações dessa assistência.Retrospective survey of the attendances outpatient physical therapy dermato-functional University PotiguarPhysical therapy is a dermato-functional knowledge area in full expansion, characterized by providing three levels of service in health care, treating different pathologies within aestheticand restorative. The University Potiguar – UNP is a pioneer institution in the state of Rio Grande 42 do Norte in the physiotherapy service dermato-functional and takes advantage of the poor access to high-cost treatments with the use of advanced features in this segment. The aim of this studywas to determine the characteristics of the population served in Clinical Dermatology, School of Physiotherapy Functional UNP. It is a descriptive, retrospective study, which analyzed the medicalrecords of 863 patients who attended physiotherapy service dermato-functional, from 2000 to 2009. There was a change in public patients attending the physiotherapy service dermato-functional, noting that in 2001 the percentage of men attending the service was up to 4.4% increased to 30.27% in 2009. We served almost 100 patients annually, treating different diseases, highlighted adiposity. Patients were, in most cases, 01 to 05 sessions, with significant dropout rate. This dropmay be related to frequent interruptions of attendance due to vacation or changes in curriculum structure every six months and may be considered one of the limitations of this assistance.Key words: Public Health.

Clostridia in Premature Neonates' Gut: Incidence, Antibiotic Susceptibility, and Perinatal Determinants Influencing Colonization

Although premature neonates (PN) gut microbiota has been studied, data about gut clostridial colonization in PN are scarce. Few studies have reported clostridia colonization in PN whereas Bacteroides and bifidobacteria have been seldom isolated. Such aberrant gut microbiota has been suggested to be a risk factor for the development of intestinal infections. Besides, PN are often treated by broad spectrum antibiotics, but little is known about how antibiotics can influence clostridial colonization based on their susceptibility patterns. The aim of this study was to report the distribution of Clostridium species isolated in feces from PN and to determine their antimicrobial susceptibility patterns. Additionally, clostridial colonization perinatal determinants were analyzed.Of the 76 PN followed until hospital discharge in three French neonatal intensive care units (NICUs), 79% were colonized by clostridia. Clostridium sp. colonization, with a high diversity of species, increased throughout the hospitalization. Antibiotic courses had no effect on the clostridial colonization incidence although strains were found susceptible (except C. difficile) to anti-anaerobe molecules tested. However, levels of colonization were decreased by either antenatal or neonatal (during more than 10 days) antibiotic courses (p = 0.006 and p = 0.001, respectively). Besides, incidence of colonization was depending on the NICU (p = 0.048).This study shows that clostridia are part of the PN gut microbiota. It provides for the first time information on the status of clostridia antimicrobial susceptibility in PN showing that strains were susceptible to most antibiotic molecules. Thus, the high prevalence of this genus is not linked to a high degree of resistance to antimicrobial agents or to the use of antibiotics in NICUs. The main perinatal determinant influencing PN clostridia colonization appears to be the NICU environment

Lack of the Delta Subunit of RNA Polymerase Increases Virulence Related Traits of Streptococcus mutans

The delta subunit of the RNA polymerase, RpoE, maintains the transcriptional specificity in Gram-positive bacteria. Lack of RpoE results in massive changes in the transcriptome of the human dental caries pathogen Streptococcus mutans. In this study, we analyzed traits of the ΔrpoE mutant which are important for biofilm formation and interaction with oral microorganisms and human cells and performed a global phenotypic analysis of its physiological functions. The ΔrpoE mutant showed higher self-aggregation compared to the wild type and coaggregated with other oral bacteria and Candida albicans. It formed a biofilm with a different matrix structure and an altered surface attachment. The amount of the cell surface antigens I/II SpaP and the glucosyltransferase GtfB was reduced. The ΔrpoE mutant displayed significantly stronger adhesion to human extracellular matrix components, especially to fibronectin, than the wild type. Its adhesion to human epithelial cells HEp-2 was reduced, probably due to the highly aggregated cell mass. The analysis of 1248 physiological traits using phenotype microarrays showed that the ΔrpoE mutant metabolized a wider spectrum of carbon sources than the wild type and had acquired resistance to antibiotics and inhibitory compounds with various modes of action. The reduced antigenicity, increased aggregation, adherence to fibronection, broader substrate spectrum and increased resistance to antibiotics of the ΔrpoE mutant reveal the physiological potential of S. mutans and show that some of its virulence related traits are increased

Enfermagem e Sindicalismo em Goiás: análise do período 1982-2004 Enfermería y Sindicalismo en Goiás: análisis del período 1982-2004 Nursing and Unionism in Goiás: analysis of the period from 1982 to 2004

Estudos sobre Sindicalismo e Enfermagem são bastante escassos no Brasil. Em Goiás, só encontramos uma monografia acerca do tema, o que nos levou a examinar a questão. Este trabalho tem como objetivo analisar o sindicalismo na área de enfermagem em Goiás, buscando reconstituir sua trajetória e evidenciar a ocorrência de articulações com outros sindicatos. A metodologia empregada (qualitativa) embasa-se na História Nova, com o emprego de fontes primárias (entrevistas e documentos originais) e secundárias. As respostas obtidas demonstraram que alguns sindicatos são mais atuantes que outros e que as diferentes possibilidades de afiliação contribuem para enfraquecer o Sindicato dos Enfermeiros de Goiás.<br>Estúdios con respecto al Sindicalismo y Enfermería son bastante raros en el Brasil.
