Prevalência da infecção por Chlamydia Trachomatis em mulheres atendidas no Programa de rastreamento do câncer de colo do útero

Genital infection with Chlamydia trachomatis is now recognized as one of the most prevalent sexually transmitted infections (STDs). Despite major advances in laboratory diagnosis techniques, primarily the character of asymptomatic chlamydial infection in both men and in women constitutes the basis for the formation of reservoirs that perpetuate transmission and acquisition of this and other STDs. The asymptomatic in women favors the rise of infection to the upper genital tract, causing injuries that can result in infertility. An examination of population screening for early detection and treatment of asymptomatic infections is the key step in combating this major public health problem. The present study aimed to evaluate the prevalence of infection by C. trachomatis in sexually active women attended the screening program for cervical cancer of the uterus in health facilities in municipalities in different regions of the State of Rio Grande do Norte, and identify factors that may contribute to the spread of this pathogen and its relationship with the lesions of the uterine cervix. It is a cross-sectional study aimed at detecting the presence of genital tract infection by C. trachomatis either in isolated form or in association with human papilloma virus (HPV) infection in asymptomatic women. Were included in this study, a total sample of 1,134 women aged 13-76, mean 34.4 years, from March 2008 to September 2012. Specimens containing exfoliated cells of the epithelium of the uterine cervix were analyzed by examining Pap cytology for the detection of possible injuries, and the polymerase chain reaction (PCR) for detection of plasmid DNA from C. trachomatis and HPV. Infection with C. trachomatis was detected with overall prevalence rate of 8.1% in the isolated form and 2.8% in co-infection with HPV. The infection was detected in 7.4% of women with normal cytology 11.5% of those with atypical cells of undetermined significance (ASC-US) and 16.7% of those with low-grade squamous intraepithelial lesion (LSIL). We observed an association between C. trachomatis and incidence of low-grade squamous intraepithelial lesion (LSIL). The genital tract infection by C. trachomatis alone was associated with education level, ethnicity and parity, revealing that women with higher education, those of non-white ethnicity and those who had three or more pregnancies were more likely to acquire infection. Levels very close to statistical significance were observed for chronological age, age at first sexual intercourse and first pregnancy. There was no association with marital status, number of sexual partners. Co-infection with C. trachomatis and HPV was detected in 2.3% of women with normal cytology, who had 5.1% in ASC-US and 10.4% in those with LSIL. No association was found between infection C. trachomatis and increased risk of HPV infection, but women with simultaneous infection by both pathogens showed greater risk for LSIL. Co-infection was more prevalent among single women, who had in the first sexual intercourse under 18 years and those who had two or more sexual partners over a lifetime

Virulência de Aphanocladium album (Preuss) Gams e Verticillium lecanii (Zimm.) Viégas (Deuteromycotina: Hyphomycetes) para o Percevejo-de-renda da seringueira, Leptopharsa heveae (Drake & Poor) (Hemiptera: Tingidae)

The lace bug, Leptopharsa heveae is an insect that causes serious damage on rubber trees. In laboratory condition, the strains of Verticillium lecanii (ARSEF 6430, 6431 e 6432) and Aphanocladium album (ARSEF 6433) were tested on third-and fifth-instar nymphs and adults of L. heveae to evaluate their virulence using 2.4 x 10(5) and 2.4 x 10(7) conidia/mL. The bioassays were carried out using Petri dishes whose inner bottoms were covered with damp filter papers. Each Petri dish contained five insects and one rubber tree leaflet. The plates were covered with PVC film to provide high relative humidity, maintained at 26 +/- 0.5 degrees C and a photophase of 14 hours. The Probit analysis was calculated from mortality date of insects killed by fungi. In the highest concentrations, ARSEF 6430 was more virulent for third instar nymphs, and the LT50 was 1.9 days. For the fifth instar, the strains ARSEF 6430, 6433 and 6432 showed similar virulence with LT50 of 2.6, 2.6 and 3.2 days, respectively. For adults, ARSEF 6431 was the most virulent strain with the LT50 recorded at 2.0 days. The smallest concentration did not always cause more than 50% mortality.

Corporeidade e humanescência na fonte dos saberes da vida: a formação de professores que valoriza o ser

The present study comes from inquietudes of an investigative posture assumed by a Physical Education Graduation Professor, before her educative action with undergraduate teachers. The research was done with 16 (sixteen) Kindergarten and Elementary School teachers, who teach at public schools. The referred teachers are undergraduate students of the Graduating Normal Course at Superior Educational Institute President Kennedy, in Natal/RN. The analysis and discussion of the intertwining of knowledge, within the four Pillars of Education, at the Fountain of Knowledge , is a metaphor, especially created for this study, as for its epistemological and methodological structure, guiding all the investigative process. It provided to show up the repercussion of bathing and drinking these humanizing waters of a pedagogical practice that values the Being, aiming his self-transcendence. The conclusions obtained were the following: 1) The professor, while bathing himself in the Fountain of Life Knowledge, reflects his personal and professional life, recalling feelings and emotions that through time were forgotten, but as they were remembered and lived again, impulse people towards humanity. 2) While bathing himself at the Fountain of Life Knowledge, the professor realizes he is awoken to humane knowledge, caring about his practices, which he develops in the classroom. Practices he considers the learning of knowing, of doing, of living together, and of learning how to be, having and integrated form on the Being. 3) When the worries about the developing of the Being exist coming from the undergraduate teacher there is a practice the shows up the web of corporeity knowledge knowing how to play, how to create, how to feel, how to think, and how to humanize. 4) The presence of the professional of Physical Education, with knowledge and experience of the budgets of corporeity, is essential in the process of graduating the Kindergarten and first years of Elementary School undergraduate teacher, for he, the former, has a huge responsibility as to the learning and developing of the educational process the humanizing developing of the Being In a proposal of education that occurs through the whole life. 5) The Professional of Physical Education has positions to conquer, for the existent gap in the educational process, as for the understanding of the body and of corporeity in the perspective of totality, urges to be modified in name of another mankind, with full humanity

Reação de clones de umezeiro (Prunus mume sieb. et zucc.) e cultivares de pessegueiro a Meloidogyne javanica (treub, 1885) Chitwood, 1949

Um amplo projeto de estudos sobre a utilização do umezeiro como porta-enxerto para pessegueiro está sendo desenvolvido na FCAV/UNESP, Câmpus de Jaboticabal-SP, devido, especialmente, às promissoras características para uso como redutor de vigor da copa e sua boa qualidade de frutos. Alguns trabalhos na literatura citam o umezeiro como resistente ao nematóide das galhas, entretanto dispõe-se de poucas informações. Neste trabalho, teve-se por objetivo estudar a reação de clones de umezeiro e cultivares de pessegueiro a Meloidogyne javanica. O experimento foi conduzido em casa de vegetação, com 6 tratamentos (Clones 05; 10 e 15 de umezeiro e as cultivares Okinawa, Aurora-1 e Dourado-1 de pessegueiro) e 9 repetições. As plantas foram mantidas em vasos de cerâmica contendo uma mistura de solo e areia (1:1, v/v), previamente autoclavada a 121ºC e 1kgf.cm-2 por 2 horas. Aos sessenta dias após o plantio, cada planta foi inoculada com 3.000 ovos e juvenis de segundo estádio de Meloidogyne javanica. Aos 100 dias após a inoculação, as plantas foram colhidas para avaliação da massa de matéria fresca do sistema radicular, número de galhas por sistema radicular, número de ovos e juvenis por 10 g de raízes, número de ovos e juvenis por sistema radicular e fator de reprodução. Verificou-se que todos os clones e cultivares de umezeiro e pessegueiro, respectivamente, mostraram-se resistentes a Meloidogyne javanica.

Parâmetros biológicos de Bemisia Tabaci (genn.) biótipo B (hemiptera: aleyrodidae) em genótipos de algodoeiro

A mosca-branca Bemisia tabaci biótipo B é uma praga de grande importância econômica para muitas culturas em todo o mundo. No Brasil, especialmente no Estado da Bahia, essa praga causou perdas que variam entre 30% e 70% em cultura de algodão. Essa pesquisa foi desenvolvida com o objetivo de avaliar parâmetros biológicos de B. tabaci biótipo B em genótipos de algodoeiro para verificar a possível ocorrência de antibiose como mecanismo de resistência sob condições de casa de vegetação. Os genótipos estudados foram IAC-23, Coodetec 406, BRS Aroeira, Fabrika, Coodetec 407, IAC-24, Makina, IAC 20-233, Coodetec 401 e CNPA Acala I. Foram avaliados os períodos de incubação e ninfal, o desenvolvimento total e a longevidade. Dos genótipos avaliados observou-se em Coodetec 406 maior período ninfal (14,7 dias) e IAC-23 a menor viabilidade de ninfas (30,7%), indicando a ocorrência de resistência do tipo antibiose contra essa mosca-branca.

Desempenho de híbridos de milho submetidos a diferentes espaçamentos e densidades populacionais

O objetivo deste trabalho foi avaliar a influência de espaçamentos entre linhas e densidades populacionais, nos componentes de produção e na produtividade de grãos, em dois híbridos de milho (Zea mays). O experimento foi conduzido na safra 2006/2007, em Latossolo Vermelho eutrófico típico, textura argilosa, em Jaboticabal, SP. O delineamento experimental de blocos ao acaso foi composto por 24 tratamentos com parcelas subsubdivididas. As parcelas principais foram constituídas por três espaçamentos entre linhas (0,40, 0,60 e 0,80 m), as subparcelas, por dois híbridos e as subsubparcelas, por quatro densidades populacionais (30 mil, 50 mil, 70 mil e 90 mil plantas por hectare). Foram avaliadas as variáveis: altura de planta e altura da inserção da primeira espiga, diâmetro de colmo, número de grãos por espiga, massa de 1.000 grãos, produtividade de grãos e índice de colheita. A produtividade do milho aumentou com a redução do espaçamento entrelinhas para os híbridos avaliados. O incremento na densidade populacional de milho resultou em aumentos na altura das plantas e na altura da inserção da primeira espiga e em redução do número de grãos por espiga. O melhor arranjo de plantas para os híbridos avaliados é de 0,40 m de espaçamento entre linhas e de 75 mil e 80 mil plantas por hectare de densidade populacional.

Maturação fisiológica de sementes de sabiá

O objetivo desta pesquisa foi estudar o processo de maturação de sementes de sabiá (Mimosa caesalpiniifolia Benth.). Foram realizadas dezesseis colheitas semanais de frutos e sementes de árvores, no município de Areia - Paraiba, no período de agosto a novembro de 2001. As colheitas iniciaram-se aos 105 dias e estenderam-se até os 210 dias após a antese. Foram avaliadas as dimensões, o teor de água e a massa fresca e seca de frutos e sementes, bem como a germinação e o vigor (primeira contagem de germinação, comprimento e massa fresca e seca das plântulas). Concluiu-se que a maturidade fisiológica das sementes de sabiá ocorre entre 154 e168 dias após a antese, podendo a colheita ser realizada até 189 dias após a antese, uma vez que a partir deste período ocorre elevada perda de frutos e sementes devido à dispersão natural.

Correlação entre os parâmetros do cortisol salivar e o fenótipo de fragilidade em idosos institucionalizados

Introduction: The Frailty Syndrome is characterized by the decrease of energy reserve and the reduced resistance to stressors. Studies indicate that the neuroendocrine markers can be related to the appearance of this syndrome. The main endocrine answer to stress is the increase of cortisol levels. Objective: To analyze the correlation between the frailty syndrome the salivary cortisol in elderly residing in nursing homes. Method: A traversal study was accomplished, in João Pessoa city, PB, with a sample composed by 69 institutionalized elderly. The collected data refer to the frailty phenotype (weight loss, exhaustion, slowness, weakness, and lower level of physical activity) and to salivary cortisol parameters (first measure - 6-7h; second measure - 11-12h; third measure - 16-17h). In the statistical analysis the Pearson s correlation test was used, Chi square Test and Anova and Simple Linear Regression analyses. Results: The sample was composed by 37.7% of men and 62.3% of women, with age average of 77.52 (±7.82). There was a percentile of 45.8% frail elderly. The frail elderly obtained higher cortisol values in the third measure (p=0.04) and the frailty load was significantly associated to the first measure (r=0.25, p=0.04). The simple linear regression analysis presented a determination rate (R2=0.05) between frailty load and first cortisol measure. Conclusion: The largest cortisol values in the morning and before sleeping among the frail elderly supply indications that can have a relationship of cortisol increase levels and the frailty presence in elderly from nursing homes.
