Com a finalidade de determinar as formas do arco dentário inferior de maior incidência na oclusão normal natural, utilizou-se um método matemático associado ao emprego de uma função polinomial, o qual foi aplicado a 63 modelos de arcadas inferiores selecionados a partir de 6118 adolescentes. Todos os indivíduos eram portadores de dentição permanente, incluindo os segundos molares, e oclusão normal natural. Em cada dente foi fixada uma esfera de vidro, que teve a função de simular o acessório do aparelho ortodôntico, sendo utilizada na medição das distâncias entre o centro da imagem dessas esferas aos eixos x e y. Após a digitalização dos modelos de gesso, as imagens foram plotadas em um programa de computador, a fim de se obterem a função polinomial de sexto grau e o gráfico dessa função para os 126 segmentos de curva, originados das secções das imagens em lado direito e esquerdo. A seguir organizaram-se esses segmentos, de acordo com as características da curvatura anterior dos arcos dentários, em oito grupos diferentes de formas, que receberam as denominações de Forma A, Forma B, Forma C, Forma D, Forma E, Forma F, Forma G, Forma H. Cada grupo foi, então, dividido em três subgrupos, conforme os tamanhos pequeno, médio e grande. Os resultados indicaram 23 formas representativas do arco dentário inferior e uma forma média para a oclusão normal natural.

Background - It is well established that the left inferior frontal gyrus plays a key role in the cerebral cortical network that supports reading and visual word recognition. Less clear is when in time this contribution begins. We used magnetoencephalography (MEG), which has both good spatial and excellent temporal resolution, to address this question. Methodology/Principal Findings - MEG data were recorded during a passive viewing paradigm, chosen to emphasize the stimulus-driven component of the cortical response, in which right-handed participants were presented words, consonant strings, and unfamiliar faces to central vision. Time-frequency analyses showed a left-lateralized inferior frontal gyrus (pars opercularis) response to words between 100–250 ms in the beta frequency band that was significantly stronger than the response to consonant strings or faces. The left inferior frontal gyrus response to words peaked at ~130 ms. This response was significantly later in time than the left middle occipital gyrus, which peaked at ~115 ms, but not significantly different from the peak response in the left mid fusiform gyrus, which peaked at ~140 ms, at a location coincident with the fMRI–defined visual word form area (VWFA). Significant responses were also detected to words in other parts of the reading network, including the anterior middle temporal gyrus, the left posterior middle temporal gyrus, the angular and supramarginal gyri, and the left superior temporal gyrus. Conclusions/Significance - These findings suggest very early interactions between the vision and language domains during visual word recognition, with speech motor areas being activated at the same time as the orthographic word-form is being resolved within the fusiform gyrus. This challenges the conventional view of a temporally serial processing sequence for visual word recognition in which letter forms are initially decoded, interact with their phonological and semantic representations, and only then gain access to a speech code.

Venous ulcers (UV) are the result of deep venous insufficiency or obstruction leading to venous hypertension in the lower limbs and lesions. Self-efficacy is the belief in the ability to successfully perform a given task or exhibit behavior that leads to a desirable outcome. Nursing needs to know and explore the influence of self-efficacy on quality of life (QOL) of people with UV, seeking to exercise holistic care. Thus, this study aimed to analyze the correlation of self-efficacy for pain control and functionality with the QOL of people with UV in primary health care. It is a cross-sectional, analytical, quantitative study with people with UV in family health strategy and mixed units in Natal / RN. We used the instruments: sociodemographic and health questionnaire, domains self-efficacy for pain control and self-efficacy for functionality of Scale of Self-Efficacy for Chronic Pain (SFCD) and the Charing Cross Venous Ulcer Questionnaire (CCVUQ). The sample included 101 people in the self-efficacy scale for functionality and 89 in self-efficacy for pain, for twelve patients reported no pain at the time of collection, and therefore were excluded from the application of the scale of selfefficacy for pain. The project was approved by the ethics committee of the Federal University of Rio Grande do Norte (CAAE No. 07556312.0.0000.5537), serving Resolution 466/12. Women predominated (66.3%), elderly (61.4%), married or in a stable relationship (63.4%), low income (90.1%) and education (85.1%), inactive (75.2%), associated chronic diseases (60.4%), more than six hours of sleep / day (82.2%), non-drinkers / smokers (80.2%), chronic injury (73.3%) and moderate to severe pain (76.2%). Self-efficacy for pain (mean 67.3, SD 26.6) was less committed to the self-efficacy for functionality (mean 59.4 SD 25.9), with statistical difference (pvalue = 0.011). No significant associations were found between self-efficacy for pain control and functionality with the sociodemographic and health characteristics. When considering the total mean CCVUQ (mean 52.1, SD 16.6), QOL of respondents tended to worsen, with the aesthetic domain the most committed (mean 57.6, SD 24.0), followed by emotional state (mean 57.0, SD 25.7), social interaction (mean 48.4, SD 21.4) and household activities (mean 43.6, SD 23.3) . We found negative and significant correlations between self-efficacy for pain and CCVUQ total score (r = -0,324; p = 0,001), the social interaction domain (r = -0,278; p = 0,008), household activities (r = - 0,285; p = 0,007) and state emotional (r = -0,247; p = 0,019). Likewise, between selfefficacy for functionality and the CCVUQ total score (r = -0,553; p < 0,001), the social interaction domain (r = -0,553; p < 0,001), household activities (r = -0,594; p < 0,001) and emotional status (r = -0,259; p = 0,009). The aesthetic domain showed negative correlation but weak and not significant with self-efficacy for pain (r = -0, 155; p = 0,147) and functionality (r = -0,189; p = 0,058). It became evident the correlation between self-efficacy for pain control and functionality and the domains social interaction, household activities and emotional state, the quality of life of people with UV

The Área de Proteção Ambiental de Jenipabu was created by Decreto 12,620/95, covering the beaches of Redinha Nova, Santa Rita and Jenipabu and Campina communities in the municipality of Extremoz, and Africa community fragment, in Natal. This protected area was created in the context of expansion of tourism in Rio Grande do Norte, in the 1990s, in which PRODETUR investments made possible the installation of infrastructure equipment, mainly in the Via Costeira and Ponta Negra beach in Natal by inserting it in the sun and sea tourism route to Northeast Brazil. In this context the beach Jenipabu in Extremoz, became one of the main attractions for those visiting Natal, due to the natural elements of its landscape, its dune field, which is offered to tourists the buggy ride. In December 1994 the excess buggy rides held in these dunes led to IBAMA ban their access to buggy for carrying out environmental study. This measure resulted in the creation of APAJ in 1995 with the goal of ordering the use and occupation to protect its ecosystems, especially the dunes, the disordered tourism. Given this context, this work aims to analyze the process of creating the APAJ and changes in the geographic space of its beaches, Redinha Nova, Santa Rita and Jenipabu, from the materialization of tourism process, as well as their implications for its residents. To this end, this paper presents a discussion of environmental currents that developed in the western portion of the globe, focusing on the need to regulate small areas of the national territory in protected areas, and an analysis of public policies that enabled the implementation tourism in APAJ as well as the laws and decrees governing the process of creation and management. Using the theory of circuits of urban economy of the Santos (2008) to analyze the territory used by tourism on the beaches of Redinha Nova, Santa Rita and Jenipabu, showing their dependent relationship with the territory used by the upper circuit on the Via Costeira and in the Ponta Negra beach and its influence on the APAJ urbanization process. Ending with the analysis of the influence of the materialization of tourism in the transformation of stocks ways of being-in-space and space-be of the Santa Rita and Jenipabu beaches in each geographical situation of APAJ among the first decades of the twentieth century to the 2014. Fieldwork was conducted between 2012 and 2014, performing actions of qualitative interviews with older residents of Santa Rita and Jenipabu beaches, interviews with structured questionnaire with merchants of APAJ and collecting GPS points trades, identifying and mapping the territory used by the lower circuit in APAJ beaches.

Epithelial changes observed in actinic cheilitis (AC) and squamous cell carcinoma of the lower lip (LLSCC) are mainly caused by chronic exposure to ultraviolet rays (UV) and are studied using different immunohistochemical markers trying to evaluate the process of carcinogenesis. The objective of this study was to comparatively evaluate the expression of Ki-67 proteins and IMP-3 in AC and LLSCC to contribute with additional information on carcinogenesis in lower lip. A total of 33 cases of AC and 33 cases of LLSCC were studied, analyzed the clinical and pathological features and immunostaining of Ki-67 and IMP-3. Immunohistochemical analysis of Ki-67 was made through the determination of the proliferation index (PI) and subsequent classification of the cases according to the scores: 0 (0% positive cells) +1 (≤30%) + 2 (> 30% and ≤60%) and +3 (> 60%). For statistical tests cases were classified as unmarked (score 0), low expression (score +1) and high expression (scores +2 and +3). For the expression of IMP-3, the percentage of immunostained epithelial cells was established, and assigned scores: 0 (corresponding to 0%), +1 (up to 30% of positive cells); +2 (From 30% to 60% of immunostained cells) and +3 (over 60% of positive cells). Statistical tests chi-square test, Mann-Whitney and Wilcoxon were used. The significance level was 5%. Most AC chaos was male (78.8%) with mean age of 50 years and cases of LLSCC also were male (69.89%) with an average of 62 years. The Ki-67 was expressed in all cases of AC and in cases of LLSCC, predominantly in the two injuries the score 2, corresponding to 81.8% of cases in ACs and 54.5% in the CELI. The expression of IMP-3 in ACs occurred in 72.7% of cases, predominantly in 36.3% of LLSCC cases score 1. Already in the IMP-3 was expressed in 60.6% of cases, especially in 27.3% of the score of the cases 3. These results allow us to conclude that the expression of IMP3 and proliferative activity are early events in carcinogenesis independently lower lip state of change.

Subsurface stratigraphic analysis of Devonian strata from the Rio do Peixe Basin, newly recognized by palynological studies, has resulted in the identification of two new lithostratigraphic units assembled in the Santa Helena Group. The Pilões Formation, the lower unit, is composed mainly of dark mudstones and medium-tovery fine-grained sandstones, with minor conglomerates and breccias. The Triunfo Formation, the upper unit, comprises whitish grey, kaolinitic, coarse-grained to conglomeratic, cross stratified sandstones and conglomerates, with interbedded mudstones and fine-grained sandstones. These units were characterized using cores, sidewall and cuttings samples, conventional logs and image log, from three wells drilled by PETROBRAS, and 3D seismic data. The Pilões Formation is interpreted as prodeltaic facies, with lesser associated subaqueous talus, debrite and sandy turbidite lobe facies, distal part of fandelta and braided fluviodeltaic facies of Triunfo Formation. The Santa Helena Group corresponds to the Lower Devonian tectono-sequence deposited in a NW-SE-trending graben during a transgressiveregressive cycle. With 343 meters of thickness (isochore) in well 1-PIL-1-PB (Pilões 1), this sequence has a non-conformity at the lower boundary and its upper boundary is an unconformity with the Lower Cretaceous tectono-sequence (Rio do Peixe Group), that represents a hiatus of about 265 million years. Ignimbrites and coignimbrite breccias (Poço da Jurema volcanic breccia), related to an unknown pyroclastic volcanic event, were recognized at the northern margin of the Sousa halfgraben. Evidence from well data suggests that this event is coeval with the Devonian graben filling. The present study indicates a polyhistorical tectono-volcanosedimentary evolution of the basin. This lithostratigraphic update brings new perspectives for geological research in the Rio do Peixe Basin, as well as in other inland basins of the Northeastern of Brazil. The results of the research also contribute to the kwnoledge of the Borborema Province and western Gondwana paleogeography during the Early Devonian.

The Chronic Venous insufficiency is characterized as a set of physical changes including how most serious complication of venous ulcers, characterized by irregular and progressive loss of continuity of the skin. The occurrence of venous ulcers in people with chronic venous insufficiency generates dependence on them with health services, with long-term treatments that cause limitations and high-impact changes, affecting their quality of life, affecting the physical, psychological, social, cultural and spiritual as an important public health problem. This study aimed to describe the experience of having a venous ulcer, in the scenario of primary health care services to Health, which includes Primary Care Units and Family Health Strategy in the city of Natal / RN, based on the life histories of users. This is a qualitative study, exploratory and descriptive, with the Oral History of Life as a methodological framework. From the ponto zero was the recruitment of participants who formed the network, totaling six employees, of both sexes and aged between 57 and 79 years. After approval by the Research Ethics Committee - UFRN under the Protocol 653 788/2014 and CAAE 30408014.0.0000.5537 was held data collection, between the months of July and August, through interviews, using identification and characterization of the instrument employees and open questions. Interviews were recorded, transcribed, transcriadas and returned to employees for a conference. The narratives were subjected to Content thematic analysis technique, according to Bardin, allowing the construction of three themes that encompass categories, namely: Axis I - Perspectives on the changes: the impact wound in social relations (changes with ulcer venous, venous ulcer and social and family relationships); Axis II - Brands in body and soul: the story of being hurt (conceptions of the body injured; therapeutic itinerary in primary care services); and Axis III - Reconstruction of being hurt: coping mechanisms (redefinition of the wounded body, resilience to chronic wound). The impact of having a chronic venous ulcer generates impact of physical, psychological and social order. As aspects related to changes after the appearance of venous ulcers, survey participants reported the presence of pain, physical limitations, psychological distress, social and emotional isolation, incapacity, aesthetic discomfort and dependency on health services; the family was the aspect thatshowed no significant change after the occurrence of wound for most participants, an ally in the therapeutic process as a support network. The redefinition of the body and the wound are the main coping mechanism of chronic condition. The services in the Primary Care Network play a fundamental role in the rehabilitation of patients with venous ulcers, although there are difficulties in accessing appropriate treatment and need for expanded services, with permanent professional training of health teams and providing the resources managers to strengthen the comprehensive care of people with venous ulcers in Health Primary Care.

Introduction: Kinesio Taping (KT) has been used in healthy people to improve neuromuscular performance, however, few studies have evaluated its chronic effects, despite being suggested. Objective: To analyze the chronic effects of KT on neuromuscular performance of the quadriceps, the oscillation of the center of pressure and lower limb function in healthy women. Methods: blinded, randomized, controlled trial, composed of 60 women (mean age 21.9 ± 3.3 years and BMI 22.3 ± 2.2 kg / m2) submitted to the evaluation of oscillation of the center of pressure through the baropodometry, the lower limb function by the hop test, isokinetic knee performance, the electromyographic activity of the vastus lateralis (VL) and joint position sense of the knee (JPS). Then, participants were randomly divided into three groups of twenty: control - did not apply the KT; placebo - application of KT without tension on the quadriceps; Kinesio Taping - application of KT with tension in the same muscle group. The evaluations were conducted in five moments: prior to application of KT, immediately after the application, 24h, 48h after application and 24 hours after its removal (72h). SPSS 20.0 was used for statistical analysis. The KS test was used to verify the data normality, the Levene test for homogeneity of variances and a mixed-model ANOVA 3x5 to check intra and inter-group differences. Results: there was no difference in peak torque, the power, nor the electromyographic activity or SPA (p> 0.05) between groups. The displacement speed of center of pressure reduced immediately after the application on kinesio taping group (p <0.001), but with no differences between the groups (p = 0.28). There was a reduction in the time of peak torque among the three groups in the evaluations after KT application (p <0.001) and an increase in single hop in all groups (p <0.001), but with no differences between them. Conclusion: KT can not change, in a chronic way, the lower limb function, the oscillation of the center of pressure, the isokinetic performance, the JPS of the knee and the electromyographic activity of VL muscle in healthy women.

Introduction: Gait after stroke is characterized by a significant asymmetry between the lower limbs, with predominant use of the non-paretic lower limb (NPLL) over using the paretic lower limb. Accordingly, it has been suggested that adding load/weight to the NPLL as a form of restricting the movement of this limb may favor the use of the paretic limb, reducing interlimb asymmetry. However, few studies have been conducted up to this moment, which only investigated the immediate effects of this practice. Objectives: 1) Investigating whether there is an influence of adding load to the NPLL during treadmill training on cardiovascular parameters and on gait performance of individuals with stroke, compared to treadmill training without load addition; 2) Analyzing the effects of treadmill training with and without load added to the NPLL on kinematic parameters of each lower limb during gait; 3) Analyzing the effects of treadmill training with and without load added to the NPLL on measurements of functional mobility and postural balance of these patients. Materials and Methods: This is a randomized single blinded clinical trial involving 38 subjects, with a mean age of 56.5 years, at the subacute post-stroke phase (with mean time since stroke of 4.5 months). Participants were randomly assigned into an experimental group (EG) or control group (CG). EG (n= 19) was submitted to gait training on a treadmill with the addition of load to the NPLL by ankle weights equivalent to 5% of body weight. CG (n= 19) was only submitted to gait training on a treadmill. Behavioral strategies which included home exercises were also applied to both groups. The interventions occurred daily for two consecutive weeks (Day 1 to Day 9), being of 30 minutes duration each. Outcome measures: postural balance (Berg Functional Balance Scale – BBS), functional mobility (Timed Up and Go – TUG; kinematic variables of 180° turning) and kinematic gait variables were assessed at baseline (Day 0), after four training sessions (Day 4), after nine training sessions (Day 9), and 40 days after completion of training (Follow-up). Cardiovascular parameters (mean arterial pressure and heart rate) were evaluated at four moments within each training session. Analysis of variance (ANOVA) was used to compare outcomes between EG and CG in the course of the study (Day 0, Day 4, Day 9 and Follow-up). Unpaired t-tests allowed for intergroup comparison at each training session. 5% significance was used for all tests. Results: 1) Cardiovascular parameters (systemic arterial pressure, heart rate and derivated variables) did not change after the interventions and there were no differences between groups within each training session. There was an improvement in gait performance, with increased speed and distance covered, with no statistically significant difference between groups. 2) After the interventions, patients had increased paretic and non-paretic step lengths, in addition to exhibiting greater hip and knee joint excursion on both lower limbs. The gains were observed in the EG and CG, with no statistical difference between the groups and (mostly) maintained at follow-up. 3) After the interventions, patients showed better postural balance (higher scores on BBS) and functional mobility (reduced time spent on the TUG test and better performance on the 180° turning). All gains were observed in the EG and CG, with no statistically significant difference between groups and were maintained at follow-up. Conclusions: The addition of load to the NPLL did not affect cardiovascular parameters in patients with subacute stroke, similar to treadmill training without load, thus seemingly a safe training to be applied to these patients. However, the use of the load did not bring any additional benefits to gait training. The gait training program (nine training sessions on a treadmill + strategies and exercises for paretic limb stimulation) was useful for improving gait performance and kinematics, functional mobility and postural balance, and its use is suggested to promote the optimization of these outcomes in the subacute phase after stroke.

Desde una estrategia metodológica múltiple, el presente trabajo aborda los aspectos sociales de una problemática ambiental compleja: el potencial restablecimiento del sistema ecológico fluvial, manejo y aprovechamiento del Río Atuel en su curso inferior. En el marco del proyecto de investigación que llevara adelante la Universidad Nacional de La Pampa denominado ?Estudio para la determinación del caudal mínimo necesario para el restablecimiento del sistema ecológico fluvial en el curso inferior del río Atuel? - un recurso natural antropizado-, en el subgrupo específico nos planteamos los siguientes objetivos, que dieron origen al presente informe: identificar los emergentes perceptivos de mayor incidencia en la dimensión ambiental y su problemática, en la población y los referentes institucionales; estudiar las prácticas sociales relativas al uso del agua en el área; sondear la afectación diferencial esperada por los distintos actores sociales e instituciones, frente a posibles cambios en los caudales del Río Atuel y las percepciones acerca de la incidencia en su calidad de vida. Focalizándo el análisis en la población local del área afectada por las problemáticas del Río Atuel y sus caudales, en los depatamentos de Cachileo y Chical Có de la Provincia de La Pampa, nos aproximamos a perspectivas y prácticas sociales propias de un escenario socio-ambiental afectado por la intensificación de las políticas provinciales de gobierno. La temática se abre en torno a la recuperación de un recurso históricamente enajenado, signada por un accionar errante del Estado, propia de una prolongada confrontación jurídica interprovincial, que promovió la intensificación de la problemática ecológica y ambiental en el área. Desde la perspectiva con que se llevó adelante el estudio consideramos que la conceptualización e intervención sociológica debe promoverse, especialmente frente a la configuración de un escenario complejo y contradictorio, en una dimensión de alto impacto en la calidad de vida y el desarrollo local
