Térmitas como bioindicadores de qualidade de habitat na caatinga, Brasil: há uma sintonia entre as variáveis estruturais dos habitats e as taxocenoses amostradas?

The composition of termite assemblages was analyzed at three Caatinga sites of the Seridó Ecological Station, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized sampling protocol for termite assemblages (30h/person/site) was conducted between September 2007 and February 2009. At each site we measured environmental variables, such as soil granulometry, pH and organic matter, necromass stock, vegetation height, tree density, stem diameter at ankle height (DAH) and the largest and the smallest crown width. Ten species of termites, belonging to eight genera and three families, were found at the three experimental sites. Four feeding-groups were sampled: wood-feeders, soil-feeders, wood-soil interface feeders and leaf-feeders. The wood-feeders were dominant in number of species and number of encounters at all sites. In general, the sites were not significantly different in relation to the environmental variables measured. The same pattern was observed for termite assemblages, where no significant differences in species richness, relative abundance and taxonomic and functional composition were observed between the three sites. The agreement between the composition of assemblages and environmental variables reinforces the potential of termites as biological indicators of habitat quality

Perfil de imunoglobulinas e correlação de autoanticorpos com a ocorrência de diversas formas clínicas em pacientes chagásicos crônicos

Introdução: O dano miocárdico na doença de Chagas resulta tanto da ação parasitária quanto da resposta imune do hospedeiro humano. O mimetismo molecular entre proteínas do Trypanosoma cruzi e vários antígenos do hospedeiro tem sido amplamente descrito gerando células T CD8+ e anticorpos autorreativos. Entretanto, a geração dos autoanticorpos e seu papel na imunopatogenia da doença de Chagas ainda não têm sido elucidados, o que nos levou, neste trabalho, a avaliar a produção de imunoglobulina G total (IgGt) e seus isotipos anti-T. cruzi, proteínas cardíacas e sua possível associação com as diferentes formas clínicas da doença de Chagas. Métodos: A produção de IgGt e isotipos foi mensurada pelo método de ELISA no soro de pacientes com as formas clínicas indeterminada (IND, n=72), cardíaca (CARD, n=47) e digestiva/cardio-digestiva (DIG/CARD-DIG, n=12) da doença de Chagas, usando como antígenos as formas epimastigota e tripomastigota do T. cruzi e proteínas cardíacas humana (miosina e troponina T). As amostras de indivíduos não infectados saudáveis (CONT, n= 30) e pacientes com cardiomiopatia isquêmica (ISCH, n=15) foram usadas como controle. Os títulos de autoanticorpos foram correlacionados com parâmetros da função cardíaca obtidos por exames eletrocardiográficos, radiográficos e ecocardiográficos. Resultados: Neste estudo foram incluídos 131 indivíduos sem diferença significativa relativa à idade ou sexo. Destes, 55% foram classificados como IND, 35,9% CARD e 9,1% DIG/CARD-DIG. Os títulos de IgGt foram mais elevados em pacientes com as formas clínicas IND, CARD e DIG/CARD-DIG do que em indivíduos CONT e ISCH usando os antígenos as formas tripomastigotas e epimastigotas do T. cruzi e, proteínas cardíacas humanas. Os pacientes com formas clínicas CARD e DIG/CARD-DIG mostraram a produção mais elevada de IgG total dirigida contra antígenos de tripomastigota e epimastigota do que os IND. Os grupos de pacientes IND e CARD apresentaram uma similar produção de IgG total específica direcionada à miosina e troponina T, e mais elevada do que em indivíduos CONT e ISCH. Há uma correlação negativa entre a produção de anticorpos anti-proteínas cardíacas com a fração de ejeção do ventrículo esquerdo (FEVE) em pacientes chagásicos crônicos. Os pacientes foram agrupados em baixo e alto produtores de autoanticorpos e comparados com a fração de ejeção demonstrando que em pacientes alto produtores de anti-troponina T (p=0.042) e miosina (p=0.013) a FEVE foi mais baixa do que os baixo produtores. A maioria dos pacientes chagásicos produz simultaneamente autoanticorpos direcionados à ambas proteínas cardíacas (r=0.9508, p=0.0001). Conclusões: Estes resultados indicam que os autoanticorpos anti- troponina T e miosina cardíaca parecem induzir redução FEVE e deve ser associado com o desenvolvimento de cardiomiopatia chagásica

Controle de qualidade físico-químico e biodisponibilidade relativa em ratos de suspensões orais de naproxeno sódico obtidas de farmácias de manipulação na cidade do Natal RN

Compounded medicines have been reported by the ANVISA due to decreased of the therapeutic response or toxicity of these formulations. The aim of this work was to investigate the physicochemical quality control among naproxen sodium oral suspensions 25 mg/mL obtained from six compounding pharmacies (A, B, C, D, E and F) and the manufactured suspension (R). In the quality control test, the tests of pH, content, homogeneity, volume and physical and organoleptic characteristics were performed according to the Brazilian Pharmacopoeia. The analytical method for determination of naproxen in suspensions was validate. This method showed excellent precision, accuracy, linearity and specificity. In the content test the suspensions B, C and E showed lower value and the F suspension showed a high value of the content. The products C and E were disapproved in the description of the physical and organoleptic characteristics test. In the pH test, three suspensions were outside specifications (C, E and F). Only the products R, A and D showed satisfactory results in these tests and therefore they were approved for relative bioavailability test. The R, A and D suspensions were orally administered to Wistar rats and the blood samples were taken at time intervals of 10, 20, 40, 60 min, 3, 4, 6, 24 and 48 h. The plasma samples were immediately stored at 80 ºC until analysis of HPLC. The bioanalytical method validation showed specificity, linearity (R2 0.9987), precision, accuracy, good recovery and stability. The chromatographic conditions were: flow rate of 1.2 mL.min-1 with a mobile phase of acetonitrile : sodium phosphate buffer pH 4.0 (50:50, v/v) at 280 nm, using a C18 column. The confidence interval of 90% for the Cmax and AUCt ratio was within the range of 80 - 125% proposed by the FDA. Only one suspension, obtained from the compounding pharmacy D, was considered bioequivalent to the rate of absorption under the conditions proposed by this study. Thus, the results indicate the need for strict supervision from the relevant authorities to ensure the patient safety and the quality of compounded drugs by pharmacies

Caracterização de estruturas planares com substratos Iso/Anisotrópicos truncados através da técnica da ressonância transversa modificada

This work presents a theoretical and numerical analysis using the transverse resonance technique (TRT) and a proposed MTRT applied in the analysis of the dispersive characteristics of microstrip lines built on truncated isotropic and anisotropic dielectric substrates. The TRT uses the transmission lines model in the transversal section of the structure, allowing to analyze its dispersive behavior. The difference between TRT and MTRT consists basically of the resonance direction. While in the TRT the resonance is calculated in the same direction of the metallic strip normal axis, the MTRT considers the resonance in the metallic strip parallel plane. Although the application of the MTRT results in a more complex equivalent circuit, its use allows some added characterization, like longitudinal section electric mode (LSE) and longitudinal section magnetic mode (LSM), microstrips with truncated substrate, or structures with different dielectric regions. A computer program using TRT and MTRT proposed in this work is implemented for the characterization of microstrips on truncated isotropic and anisotropic substrates. In this analysis, propagating and evanescent modes are considered. Thus, it is possible to characterize both the dominant and higher order modes of the structure. Numerical results are presented for the effective permittivity, characteristic impedance and relative phase velocity for microstrip lines with different parameters and dimensions of the dielectric substrate. Agreement with the results obtained in the literature are shown, as well as experimental results. In some cases, the convergence analysis is also performed by considering the limiting conditions, like particular cases of isotropic materials or structures with dielectric of infinite size found in the literature. The numerical convergence of the formulation is also analyzed. Finally, conclusions and suggestions for the continuity of this work are presented

Produção de forragem verde em sistema hidropônico usando esgoto tratado

In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of the hidroponic cultive of green forage (FVH) using treaty sewage. The production of forage was with corn (Zea mays L.), using double hybrid AG1051, in the experimental field of the Federal University of Rio Grande do Norte (UFRN), in the city of Natal-RN-Brazil. The treated effluent essentially domestic had origin of anaerobic reactor, type decant-digester of two cameras in series followed by anaerobic filters drowned. The hidroponic experimental system was composed of 08 stonemasons, with limited contours for masonry of drained ceramic brick, measuring each one 2,5 meters in length for 1,0 meter of width, with inclination of 4% (m/m) in the longitudinal sense, leveled carefully, in way to not to allow preferential roads in the flow. These dimensions, the useful area of Isow was of 2 square meters. The stonemasons of cultive were waterproof (found and lateral) with plastic canvas of 200 micres of thickness, in the white color. Controlled the entrance and exit of the effluente in the stonemasons, with cycles of 12,68 minutes, it being water of 1,18 minutes. The treatments were constituted of: T1 - 24 hours/day under it waters with flow of 2 L/min; T2 - 12 hours/day under waters with flow of 4 L/min; T3 - 12 hours/day under waters with flow of 2 L/min; and T4 - 16 hours/day under waters with flow of 3 L/min. There were evaluations of the evapotranspirometric demand, of hidroponic system affluent and effluent seeking to characterize and to monitor physical-chemical parameters as: pH, temperature, Electric Conductivity and Fecal Coliforms. This last one was analyzed to the 11 days after isow (DAS) and to the 14 DAS. The others were analyzed daily. I sow it was accomplished in the dates of February 21, 2007, first experiment, and April 10, 2007, second experiment. The density of Isow was of 2 kg of seeds, germinated before 48 hours, for square meter of stonemason. The statistic delineament was it casual entirely with two repetitions, in two experiments. It was applied Tukey test of average to five percent of probability. The cultivation cycle was of 14 DAS with evapotranspirometric demand maximum, reached by T1, of 67,44 mm/day. The analyzed parameters, as mass of green matter - Kg, productivity-Kg/m2 and reason of production of seed FVH/Kg used in Isow, the best result was presented by T1, obtaining value of up to 19,01 Kg/m2 of cultive. Without significant difference, the T4 presented greats values with 16 hours under cycle of water. The Treatments 2 and 3 with 12 hours under cycle of water, they obtained inferior results to the other Treatments. As treatment system, came efficient in the reduction of the salinity. T1 obtained reduction medium maxim of 62,5%, to the 7 DAS, in the amount of salts that enter in the system in they are absorbed in the cultivation. The cultivation FVH acted reducing the microbiologic load. Significant percentile of reduction they were reached, with up to 90,23% of reduction of Units of Colonies (UFC), constituting, like this, the Hidroponic System as good alternative of treatment of effluents of Reactors of high Efficiency

Efeitos da interação dipolar na nucleação de vórtices em nano-cilindros magnéticos

The effect of confinement on the magnetic structure of vortices of dipolar coupled ferromagnetic nanoelements is an issue of current interest, not only for academic reasons, but also for the potential impact in a number of promising applications. Most applications, such as nano-oscillators for wireless data transmission, benefit from the possibility of tailoring the vortex core magnetic pattern. We report a theoretical study of vortex nucleation in pairs of coaxial iron and Permalloy cylinders, with diameters ranging from 21nm to 150nm, and 12nm and 21nm thicknesses, separated by a non-magnetic layer. 12nm thick iron and Permalloy isolated (single) cylinders do not hold a vortex, and 21nm isolated cylinders hold a vortex. Our results indicate that one may tailor the magnetic structure of the vortices, and the relative chirality, by selecting the thickness of the non-magnetic spacer and the values of the cylinders diameters and thicknesses. Also, the dipolar interaction may induce vortex formation in pairs of 12nm thick nanocylinders and inhibit the formation of vortices in pairs of 21nm thick nanocylinders. These new phases are formed according to the value of the distance between the cylinderes. Furthermore, we show that the preparation route may control relative chirality and polarity of the vortex pair. For instance: by saturating a pair of Fe 81nm diameter, 21nm thickness cylinders, along the crystalline anisotropy direction, a pair of 36nm core diameter vortices, with same chirality and polarity is prepared. By saturating along the perpendicular direction, one prepares a 30nm diameter core vortex pair, with opposite chirality and opposite polarity. We also present a theoretical discussion of the impact of vortices on the thermal hysteresis of a pair of interface biased elliptical iron nanoelements, separated by an ultrathin nonmagnetic insulating layer. We have found that iron nanoelements exchange coupled to a noncompensated NiO substrate, display thermal hysteresis at room temperature, well below the iron Curie temperature. The thermal hysteresis consists in different sequences of magnetic states in the heating and cooling branches of a thermal loop, and originates in the thermal reduction of the interface field, and on the rearrangements of the magnetic structure at high temperatures, 5 produce by the strong dipolar coupling. The width of the thermal hysteresis varies from 500 K to 100 K for lateral dimensions of 125 nm x 65 nm and 145 nm x 65 nm. We focus on the thermal effects on two particular states: the antiparallel state, which has, at low temperatures, the interface biased nanoelement with the magnetization aligned with the interface field and the second nanoelement aligned opposite to the interface field; and in the parallel state, which has both nanoelements with the magnetization aligned with the interface field at low temperatures. We show that the dipolar interaction leads to enhanced thermal stability of the antiparallel state, and reduces the thermal stability of the parallel state. These states are the key phases in the application of pairs of ferromagnetic nanoelements, separated by a thin insulating layer, for tunneling magnetic memory cells. We have found that for a pair of 125nm x 65nm nanoelements, separated by 1.1nm, and low temperature interface field strength of 5.88kOe, the low temperature state (T = 100K) consists of a pair of nearly parallel buckle-states. This low temperature phase is kept with minor changes up to T= 249 K when the magnetization is reduced to 50% of the low temperature value due to nucleation of a vortex centered around the middle of the free surface nanoelement. By further increasing the temperature, there is another small change in the magnetization due to vortex motion. Apart from minor changes in the vortex position, the high temperature vortex state remains stable, in the cooling branch, down to low temperatures. We note that wide loop thermal hysteresis may pose limits on the design of tunneling magnetic memory cells

Avaliação clínica e comparativa da oclusão balanceada bilateral e desoclusão com guia canino sobre a função mastigatória de usuários de prótese total removível

The maintenance of masticatory function is especially important for patients who wear complete dentures due to the limitations of this type of prosthesis. Thus, the bilateral balanced occlusion (BBO) is used to achieve, besides other advantages, greater masticatory efficiency. However, analyzing critically the literature, it is observed that there is not enough scientific evidence that support the BBO as the most appropriate occlusal concept in complete dentures. This way, the purpose of the present study was to verify if complete dentures wearers with BBO present better masticatory efficiency and capacity than those with canine guidance (CG). A double-blind controlled crossover clinical trial was conducted. The sample was made of 24 completely edentulous patients. The subjects wore sets of complete dentures with both occlusal concepts for equal periods of 3 months. Objective data were collected through the masticatory efficiency test, performed by the colorimetric method, in which capsules of a synthetic material enclosing fuchsine- containing granules were used. Subjective data were recorded by patient´s ratings of their chewing function, which is the masticatory ability. No significant statistical difference was found for masticatory efficiency (p=0,0952) and masticatory ability (x2=0,5711/ p=0,4498) between the two occlusal concepts studied, as well as there was no correlation between these two variables (p=0,2985). Based on these results, it seems reasonable to use CG for the setup of complete dentures, since it is an easier and quicker technical procedure, until that future researches can come to complement this question

Avaliação da qualidade da assistência à mulher e ao filho durante o parto normal

The practices developed in the everyday life of obstetric services are sometimes out of step with the recommendations of the public health policies. Accordingly, this research had the objective of assessing the quality of the care provided to women and children during cases of natural childbirth in municipal public maternity wards of the city of Natal/RN, Brazilian Northeast. We developed a cross-sectional and quantitative study in two maternity wards that provide care actions to pregnant women at regular risk (maternity wards A and B). The participants were 314 puerperal women who were treated during the period between April and July 2014, whose children were born alive, through transpelvic way, with spontaneous or induced beginning of labor and that showed physical and emotional conditions to respond to the proposed questions. The data collection instrument was constructed on the basis of the recommendations of the World Health Organization focused on the care of normal childbirth and validated by skilled judges, and the final version has obtained optimum agreement (k = 0,96; IVC = 0,99). Associated with these recommendations, we used three indicators: percentage of women with induced labor or subjected to elective cesarean section (Indicator A); percentage of women served by a qualified health professional during labor and childbirth (Indicator B); and Bologna Index (Indicator C). The research obtained a favorable opinion of the Research Ethics Committee from the Federal University of Rio Grande do Norte, under the nº 562.313 and Certificate of Presentation for Ethics Appreciation: 25958513.0.0000.5537. The analysis of categories related to the recommendations of the World Health Organization was conducted by means of absolute and relative frequency and the Chi-square Pearson’s and Fisher’s exact tests made the comparison of the differences observed between the two maternity wards. Furthermore, we calculated the percentage of the indicators A and B and with the results of the Indicator C, the quality was assessed as follows: the closer to 5, the better will be the quality, and the closer to 0, the worst will be the quality, and the Mann-Whitney U test was used to compare the differences of the obtained averages. The significance level of 5% was considered in all statistical tests. The differences between the maternity wards were identified with regard to the provision of liquids orally (p=0,018), stimulus for non-supine positions (p=0,002), existence of partograph (p=0,001), support or welcoming by health professionals (p= 0,047), intravenous infusion (p<0,001), supine position (p<0,001), use of oxytocin (p<0,001), food and liquid restriction (p= 0,002) and, lastly, the fact of the touch is performed by more than 1 examiner (p=0,011). The indicators A and B showed percentages of 13,09% and 100%, respectively. The overall average of the Indicator C was equal to 2,07 (± 0,74). There was a statistically significant difference between the averages of the maternity wards (p<0,001). The care actions provided during the process of labor and childbirth is inappropriate, especially in the maternity ward B. It is necessary to implement improvements and redesign the obstetric model in force

Avaliação da estrutura e processo de trabalho dos centros de atenção psicossocial

Objective: Evaluate the work structure and process in Psychos ocial Care Centers (CAPS) and the professionals profile, the satisfaction, conditions and work overload. Methods: Cross - sectional study conducted in five CAPS in Campina Grande city. The study sample consisted of five coordinators, 42 graduate professional s, 26 mid - level (technical and auxiliary nurses, and caregivers), and the medical records pertaining to 413 users followed up. Data were collected using validated questionnaires (CAPSUL - rating CAPS in southern Brazil) and adapted to the study, between July and October 2014. The questionnaires were double entered and submitted to validation in the sub - program “Validate Epi Info 3.5.4” , used along with the “SPSS 17.0” for processing the statistical analyzes. Measures of central tendency and dispersion were ap plied to the descriptive analyzes; “Fisher's” exact test to check the CAPS impact on hospital admissions and the “Bonferroni” adjusted to verify the diagnoses according to sex. 5% significance level was adopted. The study was approved by the Ethics Committ ee of the Rio Grande do Norte Federal University (UFRN), protocol 719.435, of 05.30.2014. Results: From the structure analysis were identified contextual factors that influenced the work process of CAPS professionals, such as: deficiencies with regard to h uman resources; forms of health professionals employment and qualifications; temporary contract existence. As to process dimension, it was found that the home visits performance by health professionals shows to be ineffective, given its insufficiency and i rregularity, which can be explained by the high demand, reduced staff and transportation lack. It was low coverage of items inherent to Therapeutic Individual Project, as the income generation program, insertion at work and home visit. The reference and co unter reference flow are still not satisfactorily organized. There was statistically significant difference for the diagnosis, with a predominance of mood disorders related to stress among women and those related to alcohol and other drugs among men (p <0. 05). There was an association between the degree of health professionals satisfaction and working conditions, overload and factors related to the content and working conditions, the security measures, comfort and CAPS appearance, contact between the teams and users, families treatment by the teams, temporary employment relationship. Conclusion: The data collected indicate the need for the CAPS organization through increased investments in the sector in order to enhance the infrastructure as potentiating el ement of practices with a view to changing the care model for mental health proposed by the Psychiatric Reform. It is hoped therefore that this research will contribute to better planning in CAPS unit management, with another tool to improve the dimensions involving the structure and the professional work process and improve this mental health care model.

Caldo de cana desidratado na ração de codornas de corte

In order to evaluate the effect of levels of dehydrated cane juice sugar (DCJS) (0.0, 1.5, 3.0 and 4.5%) in the diet of European quail (Coturnix coturnix coturnix) on performance on performance, carcass characteristics and economical at 22 days of age indices, 192 quails cutting, were distributed in a completely randomized design with four treatments and six replicates of eight birds each There was no significant difference to the performance of quail in any of the periods. Quadratic effects of levels of DCJS on carcass weight (y = 173.71 + 4.2767x – 1.2644x², R² = 0.99), thigh-thigh more about (y = 36,055 + 1,1263x – 0,2256x², R² = 0.91) and abdominal fat (y = 3,3295 - + 0.8903x 0,19x2, R ² = 0,97) where the optimum levels were estimated 1,69; 2.50 and 2.34%, respectively. There was a linear effect descending of DCJS levels on weight breast with skin (y = 66.267 – 0.5653x, R² = 0.83) and without skin (y = 60.286 – 0.7193x, R² = 0.58). In economic analysis, one can observe higher profit to the producer with the use of conventional feed. However, between the levels of inclusion of sugar cane juice is observed that the level of 1.5% DCJS obtained the best results in economic analysis, obtaining only a difference of relative gross margin of 0.47% compared to conventional. It is recommended 1.69 and 2.50% DCJS for higher carcass, thigh + drumstick weight and lower percentage of abdominal fat quails, respectively.

“Que diferença da mulher o homem tem?”: erotismo e pornografia em Maria Teresa Horta e Carlos Drummond de Andrade

This research has the delimitation of erotic space on printed paper as a general proposition, amidst the poetic text, and therefore the real world. To do so, it proposes the comparison of two transgressor writing styles, putting together the Portuguese writer Maria Teresa Horta and the Brazilian writer Carlos Drummond de Andrade by an erotic plot, by an atopic and declassed speech to which both of them produced works, respectively, Educação Sentimental (1975) and O amor natural (1992). Has the eroticism as a combination of the masculine and feminine voices in a heterosexual relationship. It is intended to probe how the literary universe represents man and woman, and if this representation is actually socially imposed or brings to light something new. If each point of view is the view of a point, each author will talk from the top of its point of observation and experimentation, the most comfortable for itself. Therefore, it seeks to investigate eroticism itself and its relationship to everyday life, also delimiting it from what separates – or near – it from pornography and obscenity.

O eterno retorno como paródia e como colagem na filosofia da diferença de Gilles Deleuze

Gilles Deleuze hás commented on many philosophers, but his relationship with Nietzsche plays a singular role in his thought: appropriating the concept of the “eternal return” to think the central axis of his thesis, Difference and repetition (1968). Terms “difference” and “repetition” appeared associated to eternal return in his Nietzsche and philosophy (1962). Our dissertation thesis analyzes the presentations of that concept in bothworks. Chapter one presents the style construction and critical, methodological aspects of Nietzschean philosophy, fundamental elements to understand Deleuze’s interpretation. It subsequently analyzes the first presentation of that concept, expressed in the following terms: the aesthetic existence, either innocent or justified from the figure of game. We will see how the image of game implies another concept of chance, that leads Deleuze to think of an affirmative philosophical “type”, capable of creating new values. Chapter two evaluates the existential, “ethical-selective”, “physicalcosmological” character of the concept of eternal return, as much as the difficulties it imposes upon Nietzsche’s interpreter. We present afterwards Deleuzian comprehension of eternal return as a “parody” or a “simulacrum of doctrine”. Chapter three analyzes that interpretive position as a transvaluation of values from a rearrange of perspectives in order to overcome the negative comprehensions of existence. We want to question the way Deleuze builds another image of thought from the concept of eternal return – an image that, by a sort of “colagem” and selective elimination of the negativity, proposes a historiographic work and unfolds a lineage of thinkers of immanence and difference, a detour from the thought of identity, the same and the similar. We want thus to understand Deleuze’s critique of “dogmatic image of thought”.
