Abstract: Background: Cervical cancer is the main cause of cancer deaths in some developing countries. Age-related cervical cancer incidence has been fundamental for understanding the different stages of carcinogenesis concepts. No Brazilian study explored the environmental risk factors involved on cervical cancer, according to age groups taking 70’s sexual revolution in Brazil as reference. Aim: To determine the prevalence of epidemiological and clinical aspects related to cervical cancer development in a sample of three age groups of Brazilian women based on 70’s sexual revolution. Methods: A cross-section study was proceeded in a hospital-based cohort of women with altered Pap-test refereed to the National Cancer Institute for Colposcopy and treatment from October 2004 to May 2006. Two register nurses interviewed all patients ascertaining risk factors and clinical characteristics. Biopsy, partial ablation were used for CIN-1, and conization was the treatment for CIN-2/3. Results: From 318 women included in the study, 42.8% were 18 - 30 years old (born after 1975), 43.4% were 31 - 49 years old (born 1955-1975), and 13.8% were 50 - 68 years old (born 1936-1954).

Abstract: Avaliou-se tempos de incuba o in situ (144 e 288h) dos indicadores internos FDAi e FDNi e o efeito do procedimento (lavagem ou n o dos sacos de náilon durante a incuba o) em amostras da dieta, digesta duodenal e fezes bovina. O fluxo duodenal de matéria seca e a produ o fecal utilizando esses indicadores internos em compara o aoindicador externo óxido cr mico também foram estimados. Os animais receberam dietas compostas de silagem de híbridos de sorgo, concentrado ou uréia durante o experimento. O delineamento experimental adotado foi o quadrado latino 4x4 duplicado, sendo ostratamentos distribuídos em esquema fatorial (dois tempos de incuba ao x dois procedimentos de lavagem). N o houve efeito do tempo de incuba o ou procedimento na concentra o dos indicadores internos FDNi e FDAi sendo a incuba o in situ por 144h indicada para reproduzir a fra o indigestível dos indicadores nas amostras incubadas. Na estimativa da produ o fecal o indicador externo óxido cr mico apresentou resultado (1,26 kg dia-1) mais próximo ao da coleta total de fezes (1,49 kg dia-1). Para o fluxo duodenal dematéria seca, ambos indicadores internos superestimaram os resultados quando comparados ao indicador externo óxido cr mico. Times of in situ incubation (144 and 288h) for determination of internal markers IADF and INDF and the effects of differents procedures (wash or not the nylon bag every 72h incubation) was evaluated in samples of diet, duodenal digesta and cattle feces. The duodenal flow dry matter and fecal production utilizing the internal markers to compare with the external marker chromium oxide there was estimated. The animals were fed with sorgum silage, concentrate or urea. In this experiment, a latin square design was used, in a factorial scheme (two times of incubation x two processing nylon bag). No was observed effect of the incubation time or processing in the internal markers INDF and IADF concentration and the in situ incubation after 144h is adequate to reproduce the indigestible markers fraction in samples. For fecal production estimation, theexternal marker chromium oxide presented similar result (1.26 kg day-1) as the total fecal collection (1.49 kg day-1). Both the internal markers overestimate the duodenal flow dry matter when compared with the external marker chromium oxide.

Abstract: This paper was developed in order to verify the influence of nitrogen fertilization and different genotypes in the nutritional aspect and in the production of total phenols in passifloraceae. The experimental design was randomized blocks in a 5 × 2 × 2 factorial scheme, being five genotypes of Passiflora (three genotypes of Passiflora edulis, a genotype of Passiflora alata and a genotype of Passiflora ligularis), two levels of cow manure (with and without) and two doses of N (20 and 80 g), with four replicates. At 120 days after sowing, levels of foliar nutrient and total phenols were determined. Foliar N content varied depending on N doses, organic fertilization and the genotypes used. Foliar levels of P and K were higher when all genotypes received organic fertilization, while the levels of Fe and Mn were similar regardless of this fertilization. The levels of Ca and Mg were higher related to organic fertilization and the genotypes, in isolation. But the foliar contents of S, Zn and Cu increased only in relation to the used genotypes, and the average foliar content of total phenols found was 19.4 g·kg-1, ranging from 13.1 to 23.2 g·kg-1, being the lowest value observed in Passiflora alata without fertilization with cow manure. It is concluded that the nutritional requirement for N is greater for genotypes of the species Passiflora edulis in relation to the species Passiflora alata and Passiflora ligulares, and that the organic fertilization influences positively in the production of total phenols only for the genotype of sweet passion fruit.

Abstract: the effect of grinded glass and sisal fibers (25 vol%) on the cure kinetics of composites of unsaturated polyester resin (upr) was investigated by differential scanning calorimetry (dsc) and scanning electron microscopy (sem). the dsc analysis was carried out at four different heating rates (5, 10, 20 and 40 °c/min), and the cure enthalpy and activation energy (ea) were determined according to the flynn-wall-ozawa (fwo) method. the results showed that increasing heating rates promoted reduced reaction times. the sisal fiber-containing composites exhibit higher activation energy values for the cure process in comparison with the neat polyester resin and the glass fiber composites. this can be due to the presence of polar groups in the sisal components, which physically interact with the polyester resin and retard the cure reaction. hence, as sisal fiber retarded the cure reaction of the upr resin, it is suggested that the use of natural fibers in polymer matrix composites can affect the cure kinetics of the polyester resin.

Abstract: since balance dysfunction is frequent among poststroke hemiparetic patients, balance training is a fundamental goal in their rehabilitation. the purpose of this study was to assess the effects of biofeedback balance training on an unstable computerized platform in six hemiparetic patients (three men and three women, mean age 56,2 years old). subjects were assessed, before and after treatment, as to functional mobility (by the timed up-and-go test, tugt), functional reach, health-related quality of life (by the nottingham health profile), and as to equilibrium on the unstable platform. the training on an unstable computerized platform took place along 23, 30-minute sessions for 8 weeks. results showed significant improvement (p<0.001) in standing balance, of 119.1% with feet apart, and of 79.6% with feet together; a 15% increase (p<0.001) in functional reach; a 25.6% improvement in tugt (p<0.001); and a slight improvement in self-reported quality of life. the program brought thus significant improvements for the sample studied, suggesting that the biofeedback balance training as here proposed may be a valuable tool in the rehabilitation of stroke hemiparetic patients.

Abstract: here we report the subcellular localization of an intracellular serine protease of 68 kda in axenic promastigotes of leishmania (leishmania) amazonensis, using subcellular fractionation, enzymatic assays, immunoblotting, and immunocytochemistry. all fractions were evaluated by transmission electron microscopy and the serine protease activity was measured during the cell fractionation procedure using a-n-r-tosyl-l-arginine methyl ester (l-tame) as substrate, phenylmethylsulphone fluoride (pmsf) and l-1-tosylamino-2-phenylethylchloromethylketone (tpck) as specific inhibitors. the enzymatic activity was detected mainly in a membranous vesicular fraction (6.5-fold enrichment relative to the whole homogenate), but also in a crude plasma membrane fraction (2.0-fold). analysis by sds-page gelatin under reducing conditions demonstrated that the major proteolytic activity was found in a 68 kda protein in all fractions studied. a protein with identical molecular weight was also recognized in immunoblots by a polyclonal antibody against serine protease (anti-sp), with higher immunoreactivity in the vesicular fraction. electron microscopic immunolocalization using the same polyclonal antibody showed the enzyme present at the cell surface, as well as in cytoplasmic membranous compartments of the parasite. our findings indicate that the internal location of this serine protease in l. amazonensis is mainly restricted to the membranes of intracellular compartments resembling endocytic/exocytic elements.

Abstract: leptospirosis is a worldwide sanitary problem. its clinical signs resemble that of other diseases like dengue and flu, and it is difficult to distinguish between them. currently available diagnostic methods shown low sensitivity and specificity. efforts have been made to develop simpler, faster and more efficient diagnostic methods. the aim of this work was to evaluate and optimize a nested-pcr method for diagnosis of leptospirosis. primers were designed to amplify a 264 bp region within the lipl32 gene. the sensitivity and specificity of the assay was evaluated using seven saprophytic serovars and 35 pathogenic serovars. this technique showed to be very specific for pathogenic serovars, however it lacked sensitivity. in order to enhance the sensitivity, another primer pair was designed which amplify a 183 bp region within the 264 bp region in lipl32 gene, and used in a nested-pcr assay. this approach was much more sensitive than traditional pcr.
