Determination of Essential (Ca, Fe, I, K, Mo) and Toxic Elements (Hg, Pb) in Brazilian Rice Grains and Estimation of Reference Daily Intake  [PDF]
Bruno Lemos Batista, Letícia Ramos Nacano, Rodolfo de Freitas, Vanessa Cristina de Oliveira-Souza, Fernando Barbosa
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.31019
Abstract: The levels of Hg and Pb (toxic elements) and Ca, Fe, I, K, Mo (essential elements) were measured in 44 Brazilian rice samples divided among white polished (W), parboiled white (PW) and parboiled brown (PB). Rice grains were ana- lyzed by inductively coupled plasma mass spectrometry (ICP-MS). Concentrations of toxic elements varied from 0.3 to 13.4 and 0.4 to 14.5 ng?g–1 for Hg and Pb, respectively. The values for essential elements were in the same range of those for rice produced in other countries. In general parboiled samples presented higher levels of all elements in study compared to white samples. The Estimated Daily Intake through rice consumption was 0.44 μg for Pb, 0.22 μg for Hg, 0.65 μg for I, 39.5 μg for Mo, 0.43 mg for Fe, 4.1 mg for Ca and 88.9 mg for K. Our findings demonstrated that rice can contribute significantly to the RDIs of molybdenum and potassium, but it can not be considered an important source of I, Fe and Ca. Moreover, the estimated dail

Abstract: Thirty-three patients undergoing high-risk surgery were randomized either to a control group (group C, n = 16) or to an intervention group (group I, n = 17). In group I, ΔPP was continuously monitored during surgery by a multiparameter bedside monitor and minimized to 10% or less by volume loading.Both groups were comparable in terms of demographic data, American Society of Anesthesiology score, type, and duration of surgery. During surgery, group I received more fluid than group C (4,618 ± 1,557 versus 1,694 ± 705 ml (mean ± SD), P < 0.0001), and ΔPP decreased from 22 ± 75 to 9 ± 1% (P < 0.05) in group I. The median duration of postoperative stay in hospital (7 versus 17 days, P < 0.01) was lower in group I than in group C. The number of postoperative complications per patient (1.4 ± 2.1 versus 3.9 ± 2.8, P < 0.05), as well as the median duration of mechanical ventilation (1 versus 5 days, P < 0.05) and stay in the intensive care unit (3 versus 9 days, P < 0.01) was also lower in group I.Monitoring and minimizing ΔPP by volume loading during high-risk surgery improves postoperative outcome and decreases the length of stay in hospital.NCT00479011Several reports [1-4] have shown that monitoring and maximizing stroke volume by volume loading during high-risk surgery decreases the incidence of postoperative complications and the length of stay in the intensive care unit (ICU) and in the hospital. Unfortunately, this strategy has so far required the measurement of stroke volume by a cardiac output monitor as well as a specific training period for the operators [5].By increasing pleural pressure, mechanical inspiration induces cyclic variations in cardiac preload that may be turned into cyclic changes in left ventricular stroke volume and arterial pulse pressure (the difference between systolic and diastolic pressure) [6]. The variation in arterial pulse pressure (ΔPP) induced by mechanical ventilation is known to be a very accurate predictor of fluid responsiveness; tha

Abstract: Short-term experiments were carried out to study the feeding performances of the copepod Euterpina acutifrons fed on Thalassiosira weissiogii. Four adult females of this species were sorted and transferred to 15 ml glass bottles filled with different dilutions of the diatom cultures to obtain cell concentrations of 7.5, 10.0, 12.5, 15.0, 17.5, 20.0, 22.5 and 25.0 x 103 cell.ml-1 (8 treatments, 3 replicates, 4 copepods/replicate). Initial and final cell concentrations of control and experimental bottles were determined using a Neubauer Chamber. Filtration and ingestion rates were measured thought 1 hour grazing trials performed under controlled laboratory conditions. Filtration rates of Euterpina acutifrons oscillated from 0.81 to 2.92 ml. copepod-1 .h-1 and they significantly higher (p<0.05) on 7.5 x 103 cell.ml-1 concentration. Ingestion rates varied between 1.8 and 8.13 x 103 cell.copepod-1.h-1, showing significative differences (p<0.05) between treatments with low (7.5 x 103 cell.ml-1) and high (22.0 x 103 cell.ml-1) number of cells. The feeding rates of Euterpina acutifrons fed on Thalassiosira weissüogii revealed the important hole of this species of copepod on the aquatic food web of coastal ecosystems of the Amazonian region, especially on the northeast of Pará where it is commonly found.

Abstract: there is no consensus on the relevance of factors that influence gender differences in the behavior of muscles. some studies have reported a relationship between muscle tension and amplitude of the vestibular evoked myogenic potential; others, that results depend on which muscles are studied or on how much load is applied. aims: this study aims to compare vestibular evoked myogenic potential parameters between genders in young individuals. methods: eighty young adults were selected - 40 men and 40 women. stimuli were averaged tone-bursts at 500 hz, 90 dbhl intensity, and a 10-1000 hz bandpass filter with amplification of 10-25 microvolts per division. the recordings were made in 80 ms windows. study type: an experimental and prospective study. results: no significant gender differences were found in wave latency - p = 0.19 and p = 0.50 for waves p13 and n23, respectively. no differences were found in amplitude values - p = 0.28 p = 0.40 for waves p13 and n23, respectively. conclusion: there were no gender differences in latency and amplitude factors; the sternocleidomastoid muscle strain was monitored during the examination.

Abstract: Background Few studies have evaluated the association between quality of life (QoL) and functional activity limitations (FAL) of leprosy patients as determined by the Screening of Activity Limitation and Safety Awareness scale (SALSA). Aim To identify the association between FALs and the QoL of patients during and post leprosy treatment. Materials and Methods Cross-sectional survey of 104 patients with leprosy followed in specialist reference centres in Sergipe, Brazil, between June and October 2014. QoL was evaluated using the World Health Organization-QoL-BREF (WHOQoL-BREF) questionnaire. The SALSA scale was used to measure FALs. Results Low SALSA scores were present in 76% of patients. QoL scores were lower for the physical and environmental domains, with median (interquartile range (IQR)) scores of 53.6 (32.1–67.9) and 53.1 (46.9–64.8), respectively. There was a statistical association between increasing SALSA scores and lower QoL as measured by the WHOQoL-BREF. Conclusion Functional limitations are associated with lower QoL in leprosy patients, especially in the physical and environmental WHOQoL-BREF domains.

Lua Nova: Revista de Cultura e Política , 2009, DOI: 10.1590/S0102-64452009000300011
Abstract: o poder judiciário tem um importante papel nos sistemas federativos, atuando como ator político central no julgamento de litígios entre entes federados. o presente artigo tem por objetivo trabalhar com a influência deste poder no jogo federativo brasileiro, sob um aspecto específico: a forma pela qual o supremo tribunal federal (stf) julgou as a??es diretas de inconstitucionalidade (adins) impetradas por estados contra a uni?o e pela uni?o contra os estados, entre 1988 e 2002. demonstra empiricamente que as adins impetradas pela uni?o contra os estados têm maiores chances de "sucesso" do que aquelas dos estados questionando a constitucionalidade de atos da uni?o. com isso, discutimos o papel do judiciário no federalismo brasileiro, o qual parece ter contribuído, no período analisado, para o robustecimento do governo federal, em detrimento dos governos estaduais.
Judiciário e privatiza??es no Brasil: existe uma judicializa??o da política?

Abstract: the central objective of this study was to analyze the work of the judiciary branch in the privatizations process carried out in brazil during the 1990s. the article attempts to demonstrate that although the judiciary has been called on as arbiter of political conflicts, in the case of privatizations it did not respond to this demand, leaving incomplete what we refer to as a judicialization cycle, without which one cannot speak of the judicialization of politics per se. finally, the article seeks to call attention to the need to exercise greater parsimony and precision with the term "judicialization of politics", increasingly present in brazilian political science analyses.
