Abstract: The use of Pilates-based exercises for trunk strengthening has been reported in the literature. The objective of this study was to analyze and compare the electrical activity of the rectus abdominis and external oblique muscles during a traditional abdominal exercise program and an exercise program based on the Pilates method using a ball and an elastic band. The sample was composed of 10 healthy women, non-practitioners of Pilates, who performed the traditional abdominal exercise and roll-up with the ball and elastic band. The sign was normalized by the electromyographic peak of the dynamics activity and was adjusted for 2000 samples/s; the filter was set in a frequency band from 20 to 450 Hz. In the comparison between exercises, the external oblique muscle in the concentric phase had a higher recruitment in the roll-up with the ball (P =0.042). In the comparison between muscles in each exercise, the rectus abdominis showed a higher activation in the concentric phase (P = 0.009) and in the eccentric phase (P = 0.05) of the traditional abdominal exercise. Activation percentages ranged from 15% to 22%. The traditional abdominal exercise had the largest activation percentage.

Abstract: Objetivo: conhecer a soroprevalência da infec o pelo Helicobacter pylori em crian as e identificar a presen a de fatores de risco associados à sorologia positiva. Método: realizou-se um estudo transversal para o estabelecimento da soroprevalência e, posteriormente, um estudo comparativo entre as crian as com sorologias positivas e negativas. Estudadas 228 crian as, no Hospital Geral de Pediatria - Instituto Materno-Infantil de Pernambuco, entre maio e julho de 1999. Avaliou-se idade, sexo, variáveis ambientais, socioecon micas, de saúde e nutricionais; história de moradores do mesmo domicílio, com queixas digestivas e história pregressa de doen a péptica. Esses dados foram obtidos através de entrevista realizada com os pais ou responsáveis das crian as. O estado nutricional foi avaliado através dos índices antropométricos. Resultados: a soroprevalência para o Helicobacter pylori foi de 32% (IC 95% 26%-38%); 25,8% (IC 95% 17,8%-33,8%) nos pré-escolares, e de 39,4% (IC 95% 30,4% -48,4%) nos escolares. Nas crian as soropositivas, observou-se com maior freqüência ausência, no domicílio, de vaso sanitário, ou o mesmo n o tinha descarga (p=0,008), maior aglomera o domiciliar (p=0,05), uma menor renda familiar (per capita) (p=0,03) e maior número de m es que n o sabiam ler nem escrever (p=0,0002). N o houve diferen a estatística significante nos dois grupos em rela o às variáveis indicadoras de condi es de saúde, aos índices antropométricos e quanto ao contato com morador com queixas digestivas ou história pregressa de gastrite ou úlcera péptica. Conclus es: a soroprevalência da infec o pelo Helicobacter pylori foi alta na popula o estudada, sendo maior entre os escolares. Verificou-se associa o entre a soropositividade e condi es ambientais desfavoráveis.

Abstract: Objetivo: Analizar retrospectivamente los factores pronósticos y los resultados de la cirugía exclusiva o con radioterapia adyuvante de leiomiosarcomas uterinos. Material y Métodos: Desde 1992 a 2002, 18 pacientes con leiomiosarcomas uterinos fueron tratados en el servicio de oncología del Hospital Van Buren. Según FIGO: 61,1% estaba en etapa I, 5,5% en etapa II, 11,1% en etapa III y 22,2% en etapa IV. 17 % presentaban metástasis al diagnóstico. La edad promedio fue de 54,5 a os. 33,3% de las pacientes fueron operadas con el diagnóstico de leiomiosarcoma y 66,7% con otro diagnóstico, principalmente leiomioma. 61,1% de las pacientes recibieron radioterapia adyuvante. Resultados: La mediana de sobrevida global fue 13 meses. Las sobrevida global, libre de enfermedad y libre de recurrencia loco-regional fueron a 5 a os de 27,8%, 22,2% y 81,4%, respectivamente. Solamente 5,5% de las pacientes recidivaron exclusivamente en pelvis y 38,8% desarrolló metástasis a distancia exclusivas. Los factores pronósticos de sobrevida global fueron: la etapa FIGO, la cito reducción quirúrgica y la edad de las pacientes. La radioterapia adyuvante no aumentó la sobrevida global, la sobrevida libre de enfermedad, ni la sobrevida libre de recurrencia loco-regional comparado con el grupo de observación. Conclusiones: Concluimos que la histerectomía abdominal total con o sin salpingo-ooforectomía bilateral permanece como tratamiento de elección en leiomiosarcomas uterinos. La radioterapia adyuvante no tuvo impacto en resultados de tratamiento Purpose: With a retrospective study we propose to analyze the prognostic factors and results of uterine leiomyosarcomas treated with surgery alone or with adjuvant radiotherapy. Material and methods: From 1992 to 2002, 18 uterine leiomyosarcomas were treated at the department of oncology from Carlos Van Buren Hospital, corresponding to 61.1% stage I, 5.5% stage II, 11.1% stage III, and 22.2% stage IV. 17% of patients had metastatic disease at diagnosis. The mean age was 54.5 years. Preoperative diagnosis was 33.3% leiomyosarcomas and 66.7% with other diagnosis, principally leiomyoma. 61.1% of patients received adjuvant radiotherapy. Results: The median overall survival was 13 months with 5 year overall survival, disease-free survival and loco-regional disease free survival of 27.8%, 22,2% and 81,4%, respectively. Only 5.5% had recurrence disease in pelvis alone and 38.8% developed exclusively metastatic disease. Prognostic factors for overall survival were FIGO stage, surgical cytoreduction and age. Adjuvant radiotherapy does not appear to s

Abstract: The aim of this study was to compare the scores of maternal self-efficacy for child diarrhoea prevention, between intervention and control groups, according to sanitary, social and demographic characteristics. A randomised clinical trial was carried out on 163 mothers of children under 5 years old. Data collection was conducted during two months, at two different moments (M0 and M1); at the moment M0 only the intervention group watched the educational video to promote self-efficacy for child diarrhoea prevention; at M1 (two months later) the scale was applied to both groups. In the intervention group, greater mean self-efficacy scores were obtained compared with the control group. The following variables showed statistically significant associations (p < 0.05) with maternal self-efficacy: age 35 or over; high school education; working outside the home; residence with 4 to 5 people; house not of brick or mortar; public refuse collection; piped water supply; consumption of mineral water; and public sewerage network. After use of the video “Diarrhoea: you can prevent it”, the maternal self-efficacy increased, proving that this strategy is able to assist the nursing staff in educational practices.

Silva, Leandro A. da;Teixeira, Silvio C. G.;Pérez, Daniel V.;Marques, Mnica R. da C.;
Journal of the Brazilian Chemical Society , 2012, DOI: 10.1590/S0103-50532012000200026
Abstract: in this work, the impacts on the mineralogical composition and on the physico-chemical properties of two representative categories of brazilian soils - a vertisol (v) and a kandiudult (p) - after treatment with fenton reagent were studied. the clay minerals presented in the v (rich in 2:1 expansive clay) have been degraded with this reagent application. in the other, p, rich in kaolinite, there was no significant change in its clay mineralogy after this treatment. furthermore, the cation exchange capacity (cec) of v was dramatically diminished and consequently can cause the soil infertility by the reduction of water and nutrients retention.

Abstract: updated list of ant species (hymenoptera, formicidae) recorded in santa catarina state, southern brazil, with a discussion of research advances and priorities. a first working list of ant species registered in santa catarina state, southern brazil was published recently. since then, many studies with ants have been conducted in the state. with data compiled from published studies and collections in various regions of the state, we present here an updated list of 366 species (and 17 subspecies) in 70 ant genera in santa catarina, along with their geographical distribution in the seven state mesoregions. two hundred and seven species are recorded in the oeste mesoregion, followed by vale do itajaí (175), grande florianópolis (150), norte (60), sul (41), meio oeste (23) and planalto serrano (12). the increase in the number of records since 1999 results from the use of recently adopted sampling methods and techniques in regions and ecosystems poorly known before, and from the availability of new tools for the identification of ants. our study highlights the meio oeste, planalto serrano, sul and norte mesoregions, as well as the deciduous forest, mangrove, grassland and coastal sand dune ecosystems as priority study areas in order to attain a more complete knowledge of the ant fauna in santa catarina state.

Abstract: the effect of the introduction of nitrogen atoms upon the triplet excited state reactivity of 1,4-diaza-9-fluorenone (1) and 1,4-diaza-9-benz[b]fluorenone (2), in acetonitrile, was investigated employing the nanosecond laser flash photolysis technique. the intersystem crossing quantum yield (φces) for 1 and 2 was determined using 9-fluorenone as a secondary standard (φces= 0.48, in acetonitrile) and for both diazafluorenones a value of φces= 0.28 was found. quenching rate constants ranged from 8.17x104 l mol-1 s-1 (2-propanol) to 1.02x1010 l mol-1 s-1 (dabco) for 1,4-diaza-9-fluorenone and from 6.95x105 l mol-1 s-1 (2-propanol) to 5.94x109 l mol-1 s-1 (dabco) for 1,4-diaza-9-benz[b]fluorenone, depending if the quenching process involves energy, hydrogen or electron transfer. a comparison between quenching rate constants for both diazaflurenones and the parent compound, i.e. 9-fluorenone, a ketone with lowest triple state of ππ* configuration, lead to the conclusion that the reactive triplet excited state for 1,4-diaza-9-fluorenone and 1,4-diaza-9-benz[b]fluorenone has ππ* configuration.
