Objectives: to identify the demographic profile and frequency of anemia and hemoglobinopathies, as a basis for future implementation of actions aimed at pregnant women in the public health domain. Method: this is a cross-sectional study developed with pregnant women attended in a university hospital at Mato Grosso do Sul, Brazil. Blood samples were collected for the erythrogram analysis for detection of anemia and selective and specific tests for abnormal hemoglobin. The patients regarded as indigenous and mentally ill, as well as inmates, were excluded from the research, as they represent a vulnerable population which needs a cohort different from that of the sample. For data collection, a particular questionnaire was used. The research was approved by the Ethics Committee of Universidade Federal de Mato Grosso do Sul (UFMS), under the Protocol 873/2006. Results: of the 215 pregnant women under study, 20% were adolescents; 36.3% had incomplete primary education; 53.0% were non-Caucasian; 43.3% were from Campo Grande, Mato Grosso do Sul, Brazil; and 21.1% were of European descent. 17.7% had some type of anemia and, in the evaluation of hemoglobinopathies, 4.7% of patients were detected with some abnormal hemoglobin, with the following frequencies: 3.3% with HbAS; 0.9% with HbAC; and 0.5% with intermediate β-thalassemia. Conclusion: the frequencies of anemia and hemoglobinopathy found in these pregnant women showed the importance of early diagnosis, revealing indicators able to provide a basis for preventive and assistance actions for adequate clinical monitoring, reducing maternal and neonatal morbimortality in the public health services. Descriptors: pregnant women; anemia; hemoglobinopathies; public health; nursing.

Introduction: Endodontic sealer residues on dentinal surface have negative effects on adhesion of adhesives system and/or can cause discoloration of the dental crown. Objective: To evaluate the efficacy of 95% ethanol in removal of residues of epoxy-based (AH Plus), methacrylate-based (Epiphany SE) or calcium-based (Sealapex) sealers on dentinal surface. Material and methods: Thirty-two bovine incisor dental crown fragments (0.5 mm x 0.5 mm) were treated with 17% EDTA and 2.5% NaOCl. The specimens were divided into three experimental groups (n = 10): G1 (AH Plus), G2 (Epiphany SE) and G3 (Sealapex). In each group was applied a coating of one endodontic sealer type and were left undisturbed for 5 minutes. After this period, the specimens were cleaned with 95% ethanol. The control group was composed by two specimens that did not receive any sealer or cleaning treatment. The sealer residues persistence after cleaning with 95% ethanol was evaluated by scanning electron microscopy (x500) and a score system was applied. Data obtained were analyzed by Kruskal-Wallis and Dunn tests (α = 5%). Results: Moderate amount of endodontic sealer residues were observed in all groups, regardless of the endodontic sealer compositions. G1, G2 and G3 presented similar amount of sealer residues on dentinal surface after cleaning with 95% ethanol (p > 0.05). Conclusion: 95% ethanol was inefficiency to remove completely AH Plus, Epiphany SE and Sealapex residues of sealercontaminated dentin.

Introduction: Oral health can affect quality of life, and the OHIP-14 index (Oral Health Impact Profile) is useful for evaluating this impact. Objective: to investigate the impact of oral health conditions on the quality of life of patients over 50 years, assessing, initially, the consistency of the short form of the Oral Health Impact Profile index (OHIP-14). Material and method: A cross-sectional study was performed among 149 patients of two public institutions for routine dental (UNESP) and medical practice (Municipal). They were interviewed using the OHIP-14 formulary, assessing its internal consistency (Cronbach´s alpha coefficient) and the OHIP-mean (additive method). The patients were distributed according to sex, age, and education level. The comparisons of interest were made using Student´s t test at a 5% level of significance. Result: A total of consecutive patients (n = 149) participated of this study (87% response rate). Cronbach´s alpha coefficient was 0.78, denoting a good consistency of the OHIP index. The OHIP mean was 4.98. The most prevalently affected OHIP domains were dimensions of physical pain: painful aching (11.40%) and uncomfortable eating foods (21.50%). There was non-significant difference (p > 0.05) between the mean OHIP value in relation to each of gender, age, and education level. Conclusion: The OHIP-14 is a reliable instrument of assessing oral health-related quality of life, and among patients under routine practice, it was found a low impact of oral conditions on their quality of life in the studied institutions (UNESP and Municipal).

The aim of this study was to investigate the reliability of visual and digital methods to assess marginal microleakage in vitro. Materials and Methods: Typical Class V preparations were made in bovine teeth and filled with composite resin. After dye penetration (0.5% basic fuchsin), teeth were sectioned and the 53 obtained fragments were assessed according to visual (stereomicroscope) and digital methods (Image Tool Software ® -ITS) (University of Texas Health Science Center-San Antonio Dental School, USA). Two calibrated examiners (A and B) evaluated dye penetration, by means of a stereomicroscope with ×20 magnification (scores), and by the ITS (millimeters). The intra- and inter-examiner agreement was estimated according to Kappa statistics (κ), and intraclass correlation coefficient (ρ). Results: In relation to the visual method, the intra-examiner agreement was almost perfect (κA = 0.87) and substantial (κB = 0.76), respectively to the examiner A and B. The inter-examiner agreement showed an almost perfect reliability (κ = 0.84). For the digital method, the intra-examiner agreement was almost perfect for both examiners and equal to ρ = 0.99, and so was the inter-examiner agreement value. Conclusion: Visual (stereomicroscope) and digital methods (ITS) showed high levels of intra- and inter-examiner reproducibility when marginal microleakage was assessed.

In epidemiological studies, when the data is collected by interview, it is of importance to analyse the reliability of the information. This study was carried out with the purpose of examining the self-agreement of mothers in answering questions about variables of interest in oral cleft researches on two different occasions. A sample of 91 mothers of oral cleft babies were interviewed on two different occasions. The capacity of giving the same answer to questions related to heredity, type of clefts, period of gestation of the mother and birthweight were studied. The statistics type kappa (k) and intraclass correlation coefficient (r) by point and by 95% of confidence interval were applied. The intra-observer agreement for the variables history of oral clefts in the family, type of cleft, period of gestation of the mother and birthweight of the newborn was, respectively, k=0.9492, k=1.0000, k=0.9281 and r=0.9996. We concluded that the background on oral cleft in the family history of patients with this anomaly is a variable with an excellent degree of reliability. Also, the information given by the mothers related to the period of gestation, type of the baby’s cleft and birthweight are reliable.
Automatic method to classify images based on multiscale fractal descriptors and paraconsistent logic
Resumo:
In this study is presented an automatic method to classify images from fractal descriptors as decision rules, such as multiscale fractal dimension and lacunarity. The proposed methodology was divided in three steps: quantification of the regions of interest with fractal dimension and lacunarity, techniques under a multiscale approach; definition of reference patterns, which are the limits of each studied group; and, classification of each group, considering the combination of the reference patterns with signals maximization (an approach commonly considered in paraconsistent logic). The proposed method was used to classify histological prostatic images, aiming the diagnostic of prostate cancer. The accuracy levels were important, overcoming those obtained with Support Vector Machine (SVM) and Bestfirst Decicion Tree (BFTree) classifiers. The proposed approach allows recognize and classify patterns, offering the advantage of giving comprehensive results to the specialists.

The objective was to evaluate the influence of intervals without rain after the application of mixtures of carfentrazone-ethyl and glyphosate in the effectiveness of control on Commelina benghalensis. The experimental design was completely randomized with 11 treatments, with two rates of the mixture carfentrazone + glyphosate, 30 + 960 (with sequential application at 21 DAA of the mixture 20 + 960 g ha-1) and 50 + 960 g ha-1 of a.i. and five intervals of precipitation 0, 3, 6, 12 and 24 hours after application (HAA), with four repetitions, being an absolute check. The mixture was applied in post-emergence, then was carried out simulations of rain in the predetermined intervals. Were assessed the effectiveness of visual control (0 to 100 %) at 7, 14, 21, 28, 35 and 42 DAA. The results were compared by t test, with 10 % level of probability. It was observed that the application of the herbicides carfentrazone + glyphosate in the evaluated rates and even in the sequential application did not have control of C. benghalensis. The results with the second application are greater than the single application, and the best absorption of the mixture carfentrazone + glyphosate by C. benghalensis when there is a bigger interval between application and rainfall occurrence, and is necessary a minimum interval of 6 HAA for intermediate control of C. benghalensis.

I. Gunter and Christmas (1973) described the events leading to the stranding of a baleen whale on Ship Island, Mississippi, in 1968, giving the species as Balaenopteru physalus, the Rorqual. Unfortunately the identification was in error, but fortunately good photographs were shown. The underside of the tail was a splotched white, but there was no black margin. The specimen also had fewer throat and belly grooves than the Rorqual, as a comparison with True’s (1904) photograph shows. Dr. James Mead (in litt.) pointed out that the animal was a Sei Whale, Balaenoptera borealis. This remains a new Mississippi record and according to Lowery’s (1974) count, it is the fifth specimen reported from the Gulf of Mexico. The stranding of a sixth Sei Whale on Anclote Keys in the Gulf, west of Tarpon Springs, Florida on 30 May 1974, was reported in the newspapers and by the Smithsonian Institution (1974). II. Gunter, Hubbs and Beal (1955) gave measurements on a Pygmy Sperm Whale, Kogia breviceps, which stranded on Mustang Island on the Texas coast and commented upon the recorded variations of proportional measurements in this species. Then according to Raun, Hoese and Moseley (1970) these questions were resolved by Handley (1966), who showed that a second species, Kogia simus, the Dwarf Sperm Whale, is also present in the western North Atlantic. Handley’s argument is based on skull comparisons and it seems to be rather indubitable. According to Raun et al. (op. cit.), the stranding of a species of Kogia on Galveston Island recorded by Caldwell, Ingles and Siebenaler (1960) was K. simus. They also say that Caldwell (in litt.) had previously come to the same conclusion. Caldwell et al. also recorded another specimen from Destin, Florida, which is now considered to have been a specimen of simus. The known status of these two little sperm whales in the Gulf is summarized by Lowery (op. cit.).

The retaking of the ethanol program in the year 2003 as a fuel for light road transportation in Brazil through the introduction of flex fuel vehicles fleet was a good strategy to overcome the difficulties of the ethanol production sector and did work to increase its market share relative to gasoline. This process, however, may cause a future disequilibrium on the food production and on the refining oil derivates structure. In order to analyze the substitution process resultant of the competition between two opponents fighting for the same market, in this case the gasoline/ethanol substitution process, a method derived from the biomathematics based on the non-linear differential equations (NLDE) system is utilized. A brief description of the method is presented. Numerical adherence of the method to explain several substitution phenomena that occurred in the past is presented in the previous author`s paper, in which the urban gas pipeline system substitution of bottled LPG in the dwelling sector and the substitution of the urban diesel transportation fleet by compressed natural gas (CNG) buses is presented. The proposed method is particularly suitable for prospective analysis and scenarios assessment. (c) 2008 Elsevier Ltd. All rights reserved.

Thirty-eight stations were sampled in Guanabara Bay, Rio de Janeiro, Brazil, to assess the spatio-temporal diversity and biomass of sublittoral polychaetes. Samples were collected during the dry (September 2000) and rainy season (May 2001) in shallow sublittoral sediments. The polychaete spatial composition showed a heterogeneous distribution throughout the bay. A negative gradient of diversity and biomass was observed towards the inner parts of the bay and sheltered areas. A wide azoic area was found inside the bay. Some high-biomass and low-diversity spots were found near a sewage-discharge point. In these areas, the polychaete biomass increased after the rainy season. A diversified polychaete community was identified around the bay mouth, with no dramatic changes of this pattern between the two sampling periods. Deposit-feeders were dominant in the entire study area. The relative importance of carnivores and omnivores increased towards the outer sector, at stations with coarse sediment fractions. Guanabara Bay can be divided into three main zones with respect to environmental conditions and polychaete diversity and biomass patterns: A) High polychaete diversity, hydrodynamically exposed areas composed of sandy, oxidized or moderately reduced sediments with normoxic conditions in the water column. B) Low diversity and high biomass of deposit and suspension-feeding polychaete species in the middle part of the bay near continental inflows, comprising stations sharing similar proportions of silt, clay and fine sands. C) Azoic area or an impoverished polychaete community in hydrodynamically low-energy areas of silt and clay with extremely reduced sediments, high total organic matter content and hypoxic conditions in the water column, located essentially from the mid-bay towards the north sector. High total organic matter content and hypoxic conditions combined with slow water renewal in the inner bay seemed to play a key role in the polychaete diversity and biomass. Sedimentation processes and organic load coming from untreated sewage into the bay may have negatively affected the survivorship of the fauna.
