O presente estudo aborda o tema: "Relação entre Condições Bucais e a Saúde geral". O cirurgião dentista, assim como profissionais de saúde, ao fazer um diagnóstico das lesões bucais precisa considerar que essas não se restringem apenas à boca. Às vezes representam manifestações locais de doenças sistêmicas. O objetivo geral foi contribuir para uma nova postura do médico, enfermeiro e dentista, partindo da perspectiva que somos todos profissionais da saúde e, dessa forma, torna-se imprescindível ter como prática a correlação entre problemas sistêmicos e a condição bucal do paciente. Os objetivos específicos: Identificar algumas das principais doenças crônicas com relevância na Odontologia; Subsidiar o conhecimento dos profissionais de saúde no intuito de promover ações corretas de promoção e prevenção da saúde bucal; Promover a valorização da odontologia como fator imprescindível no conceito saúde. A metodologia utilizada foi uma revisão de literatura composta por informações coletadas nos livros, revistas, sites especializados, buscas nas bases de dados Lilacs e manual técnico do ministério da saúde no período de 2000 a 2011. Na conclusão foi sugerida a inserção de um novo modelo de assistência odontológica com novas políticas de saúde bucal, como também a integração da equipe buscando abordar o indivíduo como um todo.

A Hipertensão Arterial Sistêmica (HAS) é a mais prevalente de todas as doenças cardiovasculares, afetando mais de 36 milhões de brasileiros adultos, sendo a terceira causa de invalidez. Apesar da quantidade de usuários com esta doença, seu impacto pode ser revertido por meio de intervenções amplas e custo efetivo de promoção de saúde para redução de seus fatores de risco, além da melhoria da atenção a saúde, detecção precoce e tratamento oportuno. Para o enfrentamento desta doença foi elaborado um Plano de Ação utilizando o Planejamento Estratégico Situacional que consiste em um método que pressupõe constante adaptação a cada situação concreta onde é aplicado. O Plano de Ação foi aplicado na área de abrangência da Unidade Básica de Saúde de Quartel Geral, com o objetivo de aumentar o nível de conhecimento sobre a HAS e diminuir os fatores de risco das pessoas com HAS. O projeto teve uma duração de 16 semanas onde foram desenvolvidas diferentes atividades educativas, sete palestras educativas falando sobre os fatores de risco da doença, cinco audiências sanitárias, realizadas pela equipe da saúde e 400 abordagens educativas individuais pelo médico e enfermeira. A metodologia utilizada foi o tipo participativo demonstrativa com ajuda dos meios audiovisuais. Ao inicio e ao final da intervenção foi aplicado um questionário com o objetivo de avaliar o nível de conhecimentos da população adulta acima de vinte anos que participou voluntariamente da mesma. Este projeto pretende evidenciar a eficácia da intervenção, conseguindo aumentar o nível de conhecimento da população sobre HAS e os fatores de risco, assim como a importância de uma alimentação saudável, a prática de exercícios físicos sistemáticos, o controle de peso, o abandono do hábito de fumar e o uso do álcool entre outros benefícios

The aim of this work was to develop and to validate a methodology using HPLC for the simultaneous determination of folates and folic acid in foods. The limits of detection and the recovery rates for the vitamins in the certified reference materials were respectively 5 pg/mL and 94-108% for 5-MTHF, 7 pg/mL and 97-102% for THF, 30 pg/mL and 97.9-104% for 5-FTHF, 30 pg/mL and 95-107 for 10-FFA, 5 ng/mL and 97-102% for FA and 5 ng/mL and 98-103% for 10-MFA. Repeatability showed a coefficient of variation below 3.9% for all the vitamins. The proposed methodology was shown to be efficient when applied to different certified reference materials, namely pig's liver (BCR487), powdered milk (BCR421) and a vegetable mixture (BCR485).

The use of antioxidants either to prevent or retard food's lipids oxidation was approved after inquires that verified their security within a daily intake limit. In this study, the methodology was developed and validated for the analysis of synthetic antioxidants: propylgallate (PG), tert-butylhydroquinone (TBHQ), butylhydroxyanisole (BHA), octylgallate (OG) and butylhydroxytoluene (BHT) in vegetables oils, margarine and hydrogenated fats by high performance liquid chromatographic. The methodology revealed itself efficient, with recovery rates above 90% for all antioxidant substances, besides good linearity in concentration range of 40-240 mg kg-1 (r = 0,999), repeatability with CV < 3,7% and limit of quantification 16.55, 10.32, 1.40, 3.76 and 9.30 mg/kg for BHT, BHA, PG, OG and TBHQ, respectively.

The input of agrochemicals in the aquatic compartment can results in biochemical injuries for living organisms. In this context, the knowledge of alterations of enzymatic activities due the presence of agriculture pollutants contributes for the elucidation of the mechanisms of toxicity, implementation of economic methods for monitoring purposes and establishment of maximum allowed concentrations. In the present work, the above considerations are discussed, and data concerning changes in enzymatic function by pesticides and fertilizer contaminants are reviewed. Also, we focused on the acid phosphatase due its susceptibility to several pollutants and diversity in cellular functions.

This works describes the use of experimental design and surface response methodology for optimization of saponin extraction from Ampelozizyphus amazonicus. For this purpose, a method employing extraction based on maceration assisted by ultrasound technique was utilized. The following factors were studied: extraction length of time and solvent composition. The total saponin was determined by using a gravimetric method and the results expressed by their relative proportion to total crude extract. For the specific condition, 60% hydro-alcoholic solution and 18 minutes extraction length of time has shown the best results. This method can be useful for extraction of substances with biological importance

The purpose of this paper is to present a classification criterion for general chemistry experiments departing from a survey of 35 years of the experimental general chemistry discipline at the Chemistry Institute - UNICAMP. It is shown that by considering the most remarkable characteristics of an experiment and classifying it under Conceptual, Fundamental, Methodological or Quantitative criterion, teachers could better develop the discipline plan and prevent a subject superposition. Taking into account the system Fe3+/SCN- , the article also exemplify how is possible to modify an experimental approach and to conceive other procedures with different didactic purposes.

An absolute method is described via mass spectrometry (MS) for the structural assignment of isomers within the class of methylpiperidines. The method explores both the unimolecular and bimolecular gas phase behavior of structurally diagnostic fragment ions (SDFI). For the methylpiperidnes, the isomeric 2-methyl, 3-methyl and 4-methyl 2-azabutadienyl cations are found to function as SDFI. These fragment ions are expected to be formed from all members within the class, to be stable and to retain the structural information of the precursor molecule, and to not interconvert into one another. To characterize these SDFI, both the collision induced dissociation (CID) in argon and bimolecular ion/molecule chemistry with ethyl vinyl ether were compared.

The application of sand filters in localized irrigation systems is recommended in the presence of organic and algae contamination. The proper design and maintenance of these equipments are essential to assure an effective water quality control, in order to reduce the emitters clogging, to keep its water application uniformity, and to prevent increasing in the system operation costs. Despite the existence of some references about design, operation and maintenance of these filters, they are dispersed, with not enough details to guarantee the optimization of its hydraulics structure design and the proper selection of porous media to be used. Therefore, the objective of this work was to report a current literature review, relating practical information with scientific knowledge. The content of this review would help to induce and intensify the research on this subject and to contribute so the operational functions for the equipment are reached. It is also expected to assist the improvement of the filtration and flushing processes in the agricultural irrigation and the development of original design procedures and the rational use of these devices.

This paper aims to identify and analyze the reasons pointed by mothers to prolong breastfeeding beyond the first year of the child s life. The study involved 40 mothers whose children were treated in the Preventive Program of Research and Dental Treatment Center for Special Patients - Dental School of Piracicaba - UNICAMP. The group consisted of mothers who prolonged the breastfeeding beyond the baby s first year of life. All mothers were surveyed by a researcher using a specific questionnaire. In order to avoid information loss, the interviews were taped, then transcripted. Results showed that the main cause of the extended breastfeeding was maternal pleasure. It was also observed that the mother and infant attachment favors prolonged breastfeeding occurrence. Further studies should be carried out for more accurate functional analyses of variable that lead to extend breastfeeding or to wean.

The study describes the comprehension of concepts about sexuality by youths diagnosed with intellectual deficiency, during classes on sexual education. The analysis of selected episodes from video transcriptions of five classes (Human Body, Kiss, Flirting, Coitus, Condom/STD) showed: the appropriation and understanding of concepts, partial difficulties of comprehension, and inhibition. The analysis of the transcripts indicated that all students were attentive to the classes, participated in the proposed tasks, and answered the questions. The observed signs of inhibition and the expression of values were similar to those observed in other youngsters, indicating the appropriation of culturally established values. The obtained evidences contrast with mythical visions related to sexuality in these youngsters, and suggest more studies about their competences.

This paper tries to show that the developments in linguistic sciences are better viewed as stages in a single research program, rather than different ideological -isms. The first part contains an overview of the structuralistas' beliefs about the universality and equivalence of human languages, and their search for syntactic universals. In the second part, we will see that the generative program, in its turn, tries to answer why language is a universal faculty in the human species and addresses questions about its form, its development and its use. In the second part, we will see that the paper gives a brief glimpse of the tentative answers the program has been giving to each of these issues.

The main purpose of this paper is to question the relationship between theory and practice or basic and applied research in the domain of Applied Linguistics and classroom discourse. In order to achieve our aim, some theoretical texts, some recorded and transcribed classes as well as some teachers and students opinions about reading and writing were analysed. Results have shown that 1) practice is not the direct application of theoretical data: the relationship between them is not as simple as some applied linguists seem to believe because of the action of the unconscious in the constitution of subjectivity; 2) the conceptualization of the theoretical issues takes place in a confused and disorderly manner mixed up with personal experiences and previous knowledge (practice). We intend to question the fact that practice comes as secondary to theory.

In this paper I present some evidencie that forces us to conclude that within the Minimalist Program (Chomsky 1993; 1995), Binding Theory (BT) should be computed after LF (Logical Form). I show that derivations leading to structures containing violations of BT-Principles must converge at LF, since less economical alternative derivations respecting those principles are also ungrammatical. Being irrelevant to the notion of convergence, BT must apply after LF. A similar reasoning reveals that the Theta-Criterion should have the status of a bare output condition appling at LF, since less economical derivations are allowed by the computational system to prevent violations of it.

The article presents two translation models that were typical in the XVII and XVIII centuries, but can also be seen as paradigmatics in the field of Translation Studies: 1) The rhetorical model that defends the possibility of translation and emphasizes the necessity of adapting the original to the taste of the target public. 2) The model that affirms the impossibility of translation, the non-translatability: a) because the sensual elements that are linked to the language of the original are praised; b) because there is a defense of the cultural relativism and of the non-translatability between cultures; c) or because there is a defense not only of the impossibility to separate signifiers and meaning, but also because there is a definition of the signifier and of all identities as being the result of a differential game.
