Implantes nanotopograficamente modificados pela ação do laser Yb-YAG

Titanium has proven its suitability as an implant material in surgery over many years. Excellent biocompatibility and corrosion resistance are outstanding features. Implant surfaces always causes concern and interest in scientific communities, due to its close relationship with the time required for osseointegration. Surface modification can be performed by several methods, being laser irradiation one of them. Titanium implants with two different surfaces were inserted in rabbits: Group I (G-I: machined surface, control group), and group II (G-II: laser irradiated, test group) being processed 30 and 60 days after surgery for histological analysis. Surface characterization was performed with SEM-EDS, contact angle measurement, and mean roughness (Ra) parameters. Surface analysis in the GII group showed a nanomorphology affected by melt and quick solidification zones following laser irradiation (SEM), as well as total wettability and Ra mean values significantly higher than in the G-I group. The laser treatment resulted in a homogenized, porous surface, with increased surface area and volume. Histological analysis of bone-implant contact linear extension (BIC) showed better results in G-II at 30 days (39.26 ± 18.23 and 68.41 ± 13.68 for G-I and G-II groups, respectively). Titanium implants modified by laser irradiation showed important features that may accelerate early osseointegration.

Cidade média de limiar superior: um estudo a partir de Ribeirão Preto (SP)

This papper aims to discuss Ribeirão Preto as a switched-over intermediate city classification, contrastating with the concept of Metropolitan Region of Ribeirão Preto. The agribusiness sector will be analysed as the main responsible for the representation of Ribeirão Preto city as an Agribusiness Center. Due to this fact, Sertãozinho city example will be presented as Agribusiness City, where acctually concentrates the agro-industrial complex of sugarcane production, while Ribeirão Preto is in fact centralizes management activities. According to the balance of trade analysis, other elements showed up and fortifies the role of this cities. These elements unfolded the analysis of higher education guideline and shopping malls. We also analyzed the urban network of Ribeirão Preto under the concept of the Região de Influência das Cidades (REGIC) and the creation of the project Metropolitan Region of Ribeirão Preto in order to strengthen the central hypothesis as a switched-over medium sized city. In order to reach this point, besides the analysis of the data we had t literature review of the Medium Sized Cities and Urban Network concepts and Spatial Interactions and Switched- over terms

Discurso e identidade feminina na mídia impressa: a evolução da mulher no mercado de trabalho

The female identity in relation to the multiplicity of roles of contemporary women and their evolution in the labor market is the focus of the work that is developed from studies of French line Discourse Analysis refered to Michel Pêcheux and Michel Foucault. The objective is to reflect on the discursive mechanisms of print media, focusing on Veja magazines covers, which, by its verbal and visual language, constructs meaning effects and disseminates certain social thruths about the female changes. Considering that this media aspect plays an important role on society's opinion formation, it is worth to investigate, analyse and describe the elements present on the covers, as seduction and persuasion objects. The work analysis material is formed by six covers published by Veja magazine in the period of 1968-2012, which raise the theme of women in the labor market and show us their evolution and the changes in the representations about the female universe and the work in society

Corpo e identidades femininas: a intermediação das mídia

This article intends to contribute to a reflection about the relationship between the body, media and femininities, thus seeking to indicate some elements in order to clarify how the media currently interferes in this relationship, especially for the construction of female identity with the presentation of styles of femininity that are part of a particular body standard. In order to do so, we present a brief bibliographical debate on media issues, identity, discourse and power, electing as empirical choices examples of print media aimed at the female segment in Brazil and Barbie dolls.

Cenário e perspectivas para a melhoria do ensino público no Brasil: mídia, cultura e educação

Thinking about improving public education in Brazil means thinking not only on what we wish to develop, skills and abilities in individuals, but understand and clearly identify the type of citizens we are devoloping and what kind of society we want for the future. In this context it is important to note that the practice in the classroom today can not be considered without regard to education steeped in culture and, therefore, in the forms of modern communication. So if there is a crisis in education, it can not be solved only within the classroom. The challenge for school education is to show students within the classroom how they will be out of school. Quality education is a blueprint for the future, to the unknown, to a world we do not know now. In this sense, to direct the education only for the labor market is a mistake, because the market is so today, but may be another in ten or fifteen years. Precisely because we do not know what are the requirements for citizens of the future, we must focus on what is essential in the formation of our youth. Is essential then to understand the ideas, learn to discuss them, argue and learn to recognize the role of technology in social and cultural evolution of mankind.

Sexualidade, gênero e mídia: projeto de educação sexual com estudantes de comunicação e psicologia

O Projeto ´Grupo de Discussões sobre Sexualidade, Gênero e Mídia´ foi baseado na importância de dialogar sobre como os temas Sexualidade e gênero são representados nos meios de comunicação. Os participantes foram dez estudantes universitários dos cursos de Psicologia e Comunicação (Jornalismo, Rádio e Televisão, Relações Públicas e Design). O objetivo foi propiciar um espaço de diálogo entre as áreas de Psicologia e Comunicação, com discussões sobre pesquisas acadêmicas e materiais midiáticos, com discussões e reflexões que contribuíssem para a formação dos estudantes destas áreas. Foram 17 encontros semanais, com a duração de uma hora e meia, realizados em uma sala de uma Clínica de Psicologia universitária. As principais discussões versaram sobre como a mídia produz e reproduz padrões normativos, estereótipos, preconceitos e uma compreensão repressiva da sexualidade e do gênero, pensando juntos sobre formas possíveis de abordar o tema considerando a pluralidade, a diversidade e a multiplicidade da sexualidade humana. Buscou-se também refletir sobre o processo de construção dos produtos midiáticos e a importância dos profissionais que trabalham com o tema refletirem a respeito da própria história de educação sexual, a trajetória pessoal e profissional e o quanto as próprias experiências, concepções, valores e também preconce

Necessidade de ancoragem do grupo A e o controle biomecanico da mola T pré-ativada por curvatura para o fechamento de espacos

Contemporary orthodontics has sought, beyond the esthetic, occlusal and functional goals, treatments even faster and with less visits to the orthodontist — especially in patients that require dental extractions in which the generated space becomes a nuisance. The segmented arch technic (SAT), by the use of a "T" loop spring, has provided such results within these requirements. Therefore, this study aimed to appraise and demonstrate the confection, activation and biomechanical control of "T" loop spring, in the group with high anchorage necessity (group A), for retraction of anterior teeth; as well as to present a case report, with high anterior retraction necessity, treated with "T" loop spring.

Avaliação do perfil de risco de cárie dentária em gestantes de Araraquara, Brasil

The knowledge of risk of carried during pregnant is essential for an appropriate treatment using educational and preventives actions to mother for a good care of their oral health and that of children. The main objective of present retrospective study was to identify the risk of caries of pregnants (aged 15-44, mean= 25 years) came to clinic of Preventive Odontology of Araraquara-UNSEP from 1999 to 2007, using 166 medical records obtained by the third pregraduate year students, following the pre-established guidelines. The information collected includes: classification of caries risk diagnosis, pregnancy trimester, carbohydrates ingestion (between or during foods), dental plaques (O'Leary's plaque control registry) and the number of teeth with caries. The statistical analysis used the Chi2 and ANOVA tests. Most of patients showed a 25 % or more of teeth surfaces with dental plaques (92.1 %) and carbohydrates consumption among foods (89.2 %). The mean (SD) of carried and restores teeth was of 7.9 (5.1) and 4.0 (3.4), respectively and the posterior teeth were the more involved by caries/restorations. As regards the diagnosis of caries risk, classification of high risk was observed in the 38.5 % of pregnants, moderate in the 47.6 %) and low in the 13.9 %. There was a statistically significant association (p= 0.001) between the carbohydrates consumption and the diagnosis of caries risk. The plaque's rate was similar in the different trimesters of pregnancy (f= 0.223; p= 0.803). The caries risk of most pregnant women was high or moderate and it was associated with the consumption of carbohydrates.

Aspectos biológico-celulares da osseointegração baseados nas superfícies de implantes

Osseointegration involves a cascade of biological events, which can be accelerated by modifying the micro and/or nanometric topography of dental implant surfaces. Considering that different treatment types modify the titanium surface giving it a more pronounced rough topography, and physicochemical changes that appear to positively influence the osseointegration process, a literature review was made on the main types of surface treatments and their influence on the biological and cellular aspects of osseointegration, with publications dating from 1969 until the present moment. Although the precise role of the implant surface on the osseointegration of dental implants is not completely clear, the specific effects of implant surface on bone regeneration, initial kinetics, and evolution of mechanical properties have shown to be quite promising. Thus, based on dental implant surface modifications, osseointegration can be defined as a process by which rigid asymptomatic fixation of an alloplastic material can be achieved and kept in close contact with bone tissue, being resistant to early and late functional loads. This process can be modulated by an appropriate treatment of the alloplastic material surface.
