Karina Batista, Alessandra Aparecida Giacomini, Luciana Gerdes, Waldssimiler Teixeira de Mattos, Jo?o Batista de Andrade
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.58121
Abstract:

The dynamics of the weeds in the areas of crop-livestock integration is constantly changing depending on the various uses of the area. This study identified and quantified the floristic composition of weeds in areas of integration of maize for silage with Urochloa ruziziensis cv. Common at different densities of grass (0, 4 and 10 kg·ha-1) to grazing of beef cattle. The experimental design was completely randomized. A square of side0.5 m(0.25 m2area) was launched 24 times in each study area. The survey was conducted at the grain filling stage of maize. The specie contained in each frame were identified and counted. The phytosociological survey identified 9 families of weeds in areas assessed, with 7 families in every area of integrated cultivation maize with Urochloa ruziziensis at densities of 10 kg·

Abstract: we evaluated the funding of the brazilian unified national health system (sus) in municipalities with more than 100,000 inhabitants. the main goal was to evaluate the impact of policies for health resource allocation within the municipal budget. a database was organized with information from revenues reported by municipalities in the information system on government health budgets (siops) for the year 2005. reported budgets were compared and correlated to the municipalities' geographic location. we conducted a cluster analysis to create more homogeneous groups according to health-related budget. the study showed a major variability among different regions and states, with varying degrees of municipal dependence on external funds. although the large variability in sources may indicate multiple strategies for ensuring the necessary budget funds, the study suggests some barriers to public health funding in larger municipalities.

Abstract: the purpose of this work was to investigate individual values and perceptions of the organizational support to training's transfer as predictors of the impact in work training. seventy nine university graduated degree professionals, working at a hospital specialized in orthopedics' rehabilitation plus eighty five professionals, working for an state government institution, connected to the national financial system, constituted the sample of this research. all of them had finished the training event which was evaluated in this paper approximately three months ago. while at work they responded to the questionnaire, which had scales previously validated. multiple regression hierarchical analyses were made. the data shows psychosocial support and the motivational type conservationism\collectivism as an important predictor of the impact of the training at work (r2 = 0.35; p < 0.001). it also suggests that people who value conservationism, i.e., that look for respect, compromise, safety, harmony and welcoming of culture habits and ideas got more from the impact of the knowledge and abilities acquired from their professional activities. the interaction between individual values and organizational support transfer had poor significance. nonetheless, the confirmation of these data suggests that further studies should be undertaken by expanding the sample and diversifying the institutions studied.

Abstract: We investigated the NOR distribution in ten populations of Physalaemus cuvieri from different regions of Brazil and Argentina. A high variability in NOR pattern was observed and provided a useful tool in grouping several populations. The specimens from the state of Tocantins, northern Brazil, could easily be distinguished from all the other analyzed populations, since its karyotype presented NORs in the chromosome pairs 1,3,4 and 10 (and sometimes also in chromosome 5), and several pericentromeric C-bands. A NOR-site in chromosome 9 characterized three populations from the northeastern region of Brazil. Interestingly, the P. cuvieri populations located in opposite extremes of the geographic distribution had, as a fixed condition, the presence of NORs in 8q int and llp. Besides interpopulational divergences, intrapopulational variability was observed in the number of NORs, except for populations from the states of Bahia and Minas Gerais, which are boundary states respectively in the northeastern and southeastern regions of Brazil. In relation to NOR size, interindividual variations occurred in all Brazilian and Argentinean populations. Additionally, intraindividual variability in NOR size was detected in specimens from Minas Gerais. The data presented herein revealed substantial geographic polytypic variation in P. cuvieri and indicated that a taxonomic reexamination of this species is necessary.
A Review on Anti-Inflammatory Activity of Monoterpenes
Rita de Cássia da Silveira e Sá,Luciana Nalone Andrade,Dami?o Pergentino de Sousa
Molecules , 2013, DOI: 10.3390/molecules18011227
Abstract: Faced with the need to find new anti-inflammatory agents, great effort has been expended on the development of drugs for the treatment of inflammation. This disorder reduces the quality of life and overall average productivity, causing huge financial losses. In this review the anti-inflammatory activity of 32 bioactive monoterpenes found in essential oils is discussed. The data demonstrate the pharmacological potential of this group of natural chemicals to act as anti-inflammatory drugs.

Abstract: The present study aimed to investigate the correlation between structure and spasmolytic activity of racemate and enantiomers of linalyl and citronellyl acetates, chemical constituents of several bioactive essential oils, such as Thymus leptophyllus essential oil, which contains linalyl acetate as major constituent. The monoterpene esters showed significant spasmolytic activity in guinea-pig isolated ileum. Therefore, these result confirm that linalyl acetate should be involved at spasmolytic activity of the Thymus leptophyllus essential oil. The (+)-, (-)-, and (±)-linalyl acetates exhibited a relaxant effect equipotent. (+)- and (-)-Citronellyl acetates also showed a similar effect, however, synergistic action was presented on constituents of citronellyl acetate racemate. The study showed that the racemate and enantiomers of linalyl and citronellyl acetates are bioactives and that the position of the functional group on the molecule structures influences the effect of relaxation of the ileum.

Journal of Epilepsy and Clinical Neurophysiology , 2006, DOI: 10.1590/S1676-26492006000100007
Abstract: introduction: mesial temporal lobe epilepsy (mtle) is the most frequent form of partial epilepsy and has been considered a major medical and social problem as a result of its pharmacoresistence to conventional antiepileptic therapy. hippocampal sclerosis is the leading cause of mtle in surgical series and represents 50-70% of the cases. objectives: to review the clinical aspects, histological findings, and the pathogenesis of the mtle associated with the hippocampal sclerosis. results: the relation between hippocampal sclerosis and mtle is well established in the literature, although the accurate mechanism through which hippocampal sclerosis is implicated in the genesis of the epileptic seizures is still not completely understood. conclusions: retrospective studies emphasize the association between hippocampal sclerosis and history of initial precipitating injury, such as epileptic seizures, occurring in early phase of the cerebral development. recent evidences indicate that genetic factors may play a role in the genesis of hippocampal sclerosis.
Infant mortality and mothers' religious involvement in Brazil

Abstract: the growth of protestantism in brazil has been associated with changes in mortality and health-related outcomes. recent research has suggested that affiliation with protestant churches may positively influence their members' well being by: 1) providing moral directives, 2) creating formal or informal sanctions, and 3) promoting social networks and support. this article uses data from the 1996 and 2006 brazilian demographic health surveys (dhs) and cox's proportional hazard models to examine the relationship between infant mortality and mothers' religious involvement. unadjusted results show that differences in the hazard ratios of infant mortality by mothers' religious involvement are considerable and statistically significant. when one controls demographic and socioeconomic variables in the 1996 dhs, the baseline relationship disappears, supporting the hypothesis of selectivity. results using the 2006 dhs are somewhat different and suggest that the association between religious involvement and infant mortality was stronger in brazil in 2006 than in 1996. this research should encourage future studies on religious involvement and health-related outcomes in brazil. this topic deserves further consideration from brazilian demographers not simply because this country has undergone enormous changes in its religious landscape over recent decades, but also because religion can affect believers' lifestyles and behaviors, and this can indirectly influence their health and well-being.

Abstract: toxoplasma gondii causes severe fetal disease during acute infection in pregnant women, thus demanding early diagnosis for effective treatment and fetus preservation. fetal tests are inefficient and risky, and diagnosis is based on maternal igm serology, which had weak screening ability due to increased sensitivity, with alternative igg avidity tests. here, we performed elisa and avidity assays using a recombinant t. gondii antigen, rrop2, in samples from 160 pregnant women screened from a large public hospital who were referred due to positive igm assays. igg serology and avidity assays were compared using whole t. gondii extract or rrop2. elisa igg detection with rrop2 showed good agreement with assays performed with t. gondii extract, but rrop2 igg avidity assays were unrelated to whole extract antigen igg avidity, regardless of the chaotrope used. these data show that avidity maturation is specific to individual antigen prevalence and immune response during infection. elisa rrop2 igg assays may be an alternative serological test for the diagnosis of toxoplasmosis during pregnancy, although our data do not support their use in avidity assays.

Abstract: Com o objetivo de avaliar diferentes níveis de baga o e uréia como substituto ao farelo de soja em dietas para bovinos leiteiros em crescimento, dois experimentos foram realizados. No primeiro, 20 bezerros mesti os Holandês x Zebu foram distribuídos em quatro tratamentos em delineamento inteiramente casualizado. Os animais receberam dietas à base de palma forrageira e baga o de cana em níveis de 5,5; 14,4; 24,4 e 34% da matéria seca total. O ganho de peso diminuiu, enquanto a convers o alimentar, e os consumos de FDN e FDA aumentaram linearmente com a inclus o de baga o. O consumo máximo de MS foi estimado em 2,73% do peso vivo com 30% de baga o de cana. No segundo experimento foi avaliada a substitui o do farelo de soja (FS) por uréia mais milho moído (UM), em dietas à base de palma forrageira, sobre o desempenho de novilhas mesti as Holandês x Zebu. Vinte animais foram alimentados de acordo com os níveis de substitui o do FS por UM (0, 20, 40 e 60%) distribuídos em blocos ao acaso. N o houve efeito da substitui o parcial do farelo de soja por milho e uréia sobre o desempenho de novilhas mesti as.
