Concepção morfológica de fórceps, para intervenção no paciente em posição supina e o operador sentado

Ergonomics, the science of working rationalization, seeks the best relationship between man and his working tools. In Dentistry, ergonomics is present as for the professional working correctly seated, in functional comfort, intervening of supine position patient, by means of suitable equipment and instrument. Nowadays, dental equipment is justly rationalized; however, some instruments should take shape, in order to adapt those requirements. The hand tool design should permit a comfortable, non-slip and safe handling. Thus, anatomical details, the correct position of the operator for its use and specific characteristics of application should be taken into account. The instrument under analysis - forceps - was conceived according to these requirements along with a new alveolar tooth extraction technique, based on electromyographic and biomechanical studies. The morphology of the instrument, which makes possible a simple and natural kinetics of the operator, was obtained by changing the paradigm of the conventional cross-action instruments (whose grip is always on the arms of the tool), divesting the handle from the tool arm. This induced on anatomical conceiving of perpendicular handles to the extremity of the tool arm, resulting an efficient and effective instrument, according to indicated on its experimental phase

Efeito do treinamento físico aeróbio sobre o sistema cardiovascular, concentrações de nitrito/nitrato e a atividade das enzimas antioxidantes em adultos

O aumento do estresse oxidativo tem sido positivamente associado às doenças cardiometabólicas, como hipertensão arterial. Por outro lado, o exercício físico aeróbio de moderada intensidade promove efeitos benéficos tanto na prevenção quanto no tratamento das doenças cardiometabólicas. Os efeitos benéficos estão relacionados à maior produção de óxido nítrico (NO) e/ou sua maior biodisponibilidade e aumento na expressão de enzimas antioxidantes. Sendo assim, o objetivo do trabalho foi analisar o efeito do treinamento físico aeróbio (TFA) na intensidade da máxima fase estável de lactato (MFEL) sobre parâmetros cardiorrespiratórios e cardiovasculares, atividade de enzimas antioxidantes superóxido dismutase (SOD) e catalase, e concentração de nitrito/nitrato (NOx-) e malondialdeído (MDA) em adultos acima dos 40 anos de idade. Fizeram parte do estudo 55 voluntários normotensos (NT – 49,7±0,6 anos) e 32 voluntários hipertensos (HT – 52,7±1,1 anos). O desenho experimental foi realizado através do ensaio clínico controlado cruzado por dezesseis semanas. Os voluntários permaneceram oito semanas sem a realização de TFA, sendo realizadas avaliações antes (período inicial – PI) e após esse período (período intermediário – PINT). Nas oito semanas seguintes todos foram submetidos a 3 sessões/semana de TFA na intensidade da MFEL em esteira ergométrica e após foi novamente realizada a avaliação (período final – PF). As avaliações consistiram de medições da pressão arterial (PA) de repouso (método auscultatório), frequência cardíaca (FC) de repouso e exercício (Polar® - RSX-800CX), testes de VO2 máximo (teste de 1 milha) e coletas de sangue (12 horas de jejum noturno). Amostras de plasma e soro foram utilizadas para análises da atividade da SOD, catalase, concentrações NOx- e MDA. O protocolo para determinação da MFEL foi de acordo com Beneke et al (2003). Para análise estatística foi...

Análise de dados pedogeoquímicos de multielementos visando o refinamento de mapeamento geológico de detalhe em alvos de Pb-Zn nos municípios de Adrianópolis, Cerro Azul e Tunas do Paraná (Vale do Ribeira, PR)

In order to to research, the region of Perau, base metal mineralization, Grupo Votorantim Metals conducted a soil sampling on targets predetermined holding its chemical analysis. These reviews have been provided by the company for this work was to evaluate the potential use of these data pedogeochemical multi-element for refinement of the work of geological mapping. We selected six targets: Varginha, Salvador, Guararema Taquara Lisa and Coffin of Mendes, in the municipalities of Adrianople, Cerro Azul and Tunas do Paraná, located in Vale do Ribeira (PR). Both have about 10 km2 and situated in the geological context of the Fold Belt Terrane and the Massif de Joinville. The main rock types are present metasedimentary rocks of low to medium grade metamorphic, interspersed the amphibolites ortoderivados, both belonging to the Complex Perau, gneisses and migmatitic Complex. Applied to the geochemical data descriptive statistical techniques (variogram, kriging and histogram). From the correlation between the distributions of elements with the geological data, we could assess the potential of the proposed methodology.

Plano real e a nova realidade brasileira

This paper analyzes the Real Plan and its effects on two administrations of President Fernando Henrique Cardoso (FHC), a period which extends from 1995 to 2002. To this end, the study includes a brief review of the problems faced by previous plans, especially the Cruzado Plan and the reasons for the belief that it has been successfull in relation to inflation control. Additionally, seeking to describe the process of moving to the new currency towards stabilization, the paper describes the theoretical foundations of the Plan. In sequence, it defines the backround of both international and domestic monetary reform which was one important part of the Plan and therefore the reasons for the implementation of the monetary reform. Subsequently the paper deals with the effects of the Plan on the economy as a whole, covering also the way the economic measures were taken concerning the Mexican and Asian crisis, the policies used fot the exchange rate, interest rate, fiscal accounts, balance of payments, among other factors and the relationship between them. Hence, it describes the immediate and the long-term consequences of stabilization program in terms of output, employment, public deficit and debt. Therefore, it is important to note the various junctures to which the economy was exposed, and also to point out the challenges and obstacles arising from these changes for growth, which was sometimes fast, sometimes slowing down - the so-called stop and go. Of course, facts as the moving to floating exchange rate regime, the adoption of inflation targeting regime and the adoption of fiscal responsibility law along with the primary surplus policy were able to create a new economic environment and to contribute to later success of the Cardoso years

Rentabilidade na semeadura cruzada da cultura da soja

Soybean cross-seeding tillage came from better spatial arrangement of plants per area, so some producers have opted for this tillage system, which consists in seeding the area in two steps, forming a chessboard with perpendicular lines of tillage. This study aims to analyse the soybean productivity and production costs when it planted in different dispositions of crossed tillage. The experiment was conducted during the harvests 2011/2012 and 2012/2013 at Lageado Farm of the FCA/UNESP, Botucatu-SP, in an area cultivated under no-tillage. The experimental design was in randomized block with five treatments and eight replications. The treatments were: seeding in parallel rows with recommended fertilization and recommended plant population (conventional); cross-seeding with doubled fertilization and doubled plant population; cross-seeding with recommended plant population and doubled fertilization; cross-seeding with doubled plant population and recommended fertilization; cross-seeding with fertilization and recommended plant population. The results showed statistical difference among the treatments, with increased productivity for the cross-seeding with doubled plant population and recommended fertilization. However the conventional tillage with parallel lines shows higher net earnings than soybean cross-seeding, being more profitable for producer.

Efeito de soluções fluoretadas contendo xilitol e sorbitol no número de estreptococos do grupo mutans na saliva de seres humanos

The objective of this study was to assess the effect of 0.05% sodium fluoride solutions containing 2.5% or 12.5% xylitol on the number of Streptococcus mutans in the human mouth. Fifty boys between 8 and 16 years of age participated in this double-blind crossover study. Of the original 50 boys, 33 finished the study. Participants were randomly divided into four groups. The following solutions were employed: placebo solution; 0.05% sodium fluoride solution; 0.05% sodium fluoride + 2.5% xylitol + 2% sorbitol; 0.05% sodium fluoride + 12.5% xylitol + 2% sorbitol. Each solution was used for a 28-day period (20 mL/day, twice a day), with a 10-day washout period between solutions. There were no significant differences (P = 0.32) between the two xylitol-containing solutions (2.5% vs. 12.5%) concerning the number of Streptococcus mutans. However, there was a significant difference between these two xylitol-containing solutions and the sodium fluoride and placebo solutions (P < 0.001). Our results suggest that the 0.05% sodium fluoride solutions containing either 2.5% or 12.5% xylitol caused a significant reduction in the number of Streptococcus mutans.

Ocorrência de lesões de ligamentares e músculo tendíneas ao longo das fases do ciclo menstrual de atletas de alto redimento: um estudo de caso longitudinal

Female athletes are more susceptible to injury when compared with males. This increased risk of injury, may be caused by fertile-menstrual cycle. The aims of this study were to investigate the prevalence in the occurrence of muscle-tendon and ligament injuries in different phases of the menstrual cycle over a period of high performance sports training and identify possible differences of occurrences between the phases. Fifteen female athletes, members of a women's basketball team, with ages between 15 and 22 years (average 17.5 ± 2.6 years), with regular menstrual cycles and daily practitioners of training, received follow-up during the menstrual cycle for 5 months. During the period were noted occurrences of injury in relation to the menstrual period of each athlete. The results showed 13 injuries, all of anterior cruciate ligament. The distribution of percentage values indicated a significantly higher risk of athletes suffer injuries in the follicular phase. The result makes us believe that significant elevations in the concentrations of estrogen in this fertile menstrual cycle phase, more open women to a higher risk of performing different injuries.
