A documentação odontológica sob a ótica dos cirurgiões-dentistas de Natal-RN

The dental documentation or handbook is a collection of documents produced by the professional with diagnostic and therapeutical purpose where the inherent information to the buccal and general health of patients are registered. The register and proper filling of these documents, taking care of the ethical and legal requirements, provide to the dentist the possibility to contribute with justice in cases of human identification and makes of these documents an essential element of evidence in the ethical processes, administrative, civil and criminal against the dentists. Ahead of this fact, understanding such requirements and the importance of the dentist to register himself adequately, this research verified the knowledge of Natal (RN) City s dentists with relation to the elaboration of the dental handbook, investigating the concepts and the importance attributed to the handbook, identifying the documents more used and filed by these professionals, besides inquiring the legal value of filed documents and the filling time of these ones. The sample was constituted by 124 dentists, who had answered a questionnaire, after having been randomly selected ITom a list of professionals subscribed in the Dentistry Local Council/RN Section. The analysis of the results showed that majority of the participant citÍzens (52,3%) confers to the dental documentation the clinical importance, followed by the legal and forensic-dentistry importance; 59,3% of the searched professionals do not distinguish satisfactorily or they do not observe differences between the dental handbook and the clinical filing card, the X-rays, the dental certificates, the prescriptions, the directions and the receipts; between the documents of common use to clínical and specialist ones, the contract of rendering of services and term of ITee and cleared up consent are the documents less used by the professionals. It was still verified, that only 13,1% of the sample register the signature of the patients in the clinical filing card, making it more credibility to be presented in judgement. In the same way, copies of dental certificates and prescriptions evaluated and signed by the patients are filed respectively by only 13,5% and 9,4% ofthe searched professionals and 50% ofthe sample, keep these documents filed for an indeterminate period of time, that is, these professionals have the guard of the handbook and they do not intend to disdain it, although 85,5% of the sample does not recognize the real proprietor of the handbook. It is concluded that a great part of the dentists is unaware about the importance of the dental documentation, and neglect its elaboration, leaving themselves exposed to several kinds of penalties foreseen in the legislation

Bark and ambrosia beetle (Coleoptera : Scolytidae) responses to volatiles from aging loblolly pine billets

Many species of bark and ambrosia beetles use host volatiles as cues for breeding site location. In a study where the objectives were to identify the different volatiles released by Pinus taeda L. billets as they age, to determine the arrival sequence of scolytids (Colcoptera: Scolytidae), and to correlate volatile emission by the billets with beetle catches, 25 species of scolytids were trapped. Bark beetles were more attracted to the billets in the beginning of the period. whereas ambrosia beetles arrived later. Among the bark beetles, Dendroctonus terebrans (Olivier) was significantly more attracted during the Ist 3 wk after tree felling, Hylastes tenuis Eichhoff in the Ist 2 wk. Pityophtorus pulicarius (Zimmermann) in weeks 2 and 3, and Ips grandicollis (Eichhoff) was more attracted on weeks 3 and 4. Among the ambrosia beetles, Xyleborinus saxeseni (Ratzeburg) was more attracted to billets during weeks 4-6, whereas Xyleborus pubescens Zimmermann and Xyleborus californicus Wood were more attracted during week 6. The billets showed marked decline in attractiveness to all scolytids after 8 wk. Volatiles collected during the beetle trapping periods included 15 hydrocarbon monoterpenes, 18 oxygenated monoterpenes, 4-allylanisole, and ethanol. The hydrocarbon monoterpenes and 4-allylanisole decreased sharply over time, but oxygenated monoterpenes and ethanol increased up to weeks 4-6, after which they also decreased. Good correlations between certain billet volatiles and catches for some beetle species were obtained, but their biological significance could not be determined.

Alterações da margem palpebral associadas ao ectrópio

OBJETIVO: Investigar alterações da margem palpebral em portadores de ectrópio. MÉTODOS: Foi feito estudo observacional, do qual participaram 53 portadores de ectrópio palpebral e 25 portadores de dermatocálase (grupo controle), estudando-se, a partir de imagens digitais, a posição dos cílios e a presença de inflamações na margem palpebral. Os dados foram submetidos a análise estatística. RESULTADOS: Os portadores de ectrópio apresentaram com maior freqüência diminuição do número de cílios, perda da convexidade, triquíase e distiquíase quando comparados aos indivíduos do grupo controle. CONCLUSÃO: O portador de ectrópio possui alterações da margem palpebral provavelmente decorrentes do processo inflamatório crônico que ocorre na região.

Duffin-Kemmer-Petiau and Klein-Cordon-Fock equations for electromagnetic, Yang-Mills and external gravitational field interactions: proof of equivalence

Starting from the Generating functional for the Green Function (GF), constructed from the Lagrangian action in the Duffin-Kemmer-Petiau (DKP) theory (L-approach) we strictly prove that the physical matrix elements of the S-matrix in DKP and Klein-Gordon-Fock (KGF) theories coincide in cases of interacting spin O particles with external and quantized Maxwell and Yang-Mills fields and in case of external gravitational field (without or with torsion), For the proof we use the reduction formulas of Lehmann, Symanzik and Zimmermann (LSZ). We prove that many photons and Yang-Mills particles GF coincide in both theories too. (C) 2000 Elsevier B.V. B.V. All rights reserved.

The GHEP-EMPOP collaboration on mtDNA population data-A new resource for forensic casework

Mitochondrial DNA (mtDNA) population data for forensic purposes are still scarce for some populations, which may limit the evaluation of forensic evidence especially when the rarity of a haplotype needs to be determined in a database search. In order to improve the collection of mtDNA lineages from the Iberian and South American subcontinents, we here report the results of a collaborative study involving nine laboratories from the Spanish and Portuguese Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) and EMPOP. The individual laboratories contributed population data that were generated throughout the past 10 years, but in the majority of cases have not been made available to the scientific community. A total of 1019 haplotypes from Iberia (Basque Country, 2 general Spanish populations, 2 North and 1 Central Portugal populations), and Latin America (3 populations from São Paulo) were collected, reviewed and harmonized according to defined EMPOP criteria. The majority of data ambiguities that were found during the reviewing process (41 in total) were transcription errors confirming that the documentation process is still the most error-prone stage in reporting mtDNA population data, especially when performed manually. This GHEP-EMPOP collaboration has significantly improved the quality of the individual mtDNA datasets and adds mtDNA population data as valuable resource to the EMPOP database (www.empop.org).

Equivalence of the Duffin-Kemmer-Petiau and Klein-Gordon-Fock equations

A strict proof of the equivalence of the Duffin-Kemmer-Petiau and Klein-Gordon Fock theories is presented for physical S-matrix elements in the case of charged scalar particles minimally interacting with an external or quantized electromagnetic field. The Hamiltonian canonical approach to the Duffin - Kemmer Petiau theory is first developed in both the component and the matrix form. The theory is then quantized through the construction of the generating functional for the Green's functions, and the physical matrix elements of the S-matrix are proved to be relativistic invariants. The equivalence of the two theories is then proved for the matrix elements of the scattered scalar particles using the reduction formulas of Lehmann, Symanzik, and Zimmermann and for the many-photon Green's functions.

Polyethylene gel in the subcutaneous tissue of rats: Histopathologic and systemic evaluation

Purpose: To evaluate the histological and systemic response to subcutaneous injection of polyethylene gel in rats. Methods: Twenty-one white male rats were divided into 3 groups (G): G1 and G2 received subcutaneous polyethylene gel injection in the dorsal midline and were sacrificed at 30 and 60 postoperative days, respectively. G3 was not exposed to the polyethylene gel and was sacrificed after 60 days. Blood levels of lactate dehydrogenase (LDH), creatine kinase (CK), and alkaline phosphatase (ALP) were evaluated. The heart, kidney, liver, adrenal gland, injection site, and adjacent tissues were histologically examined. The results were submitted to statistical analysis. Results: There was no clinical evidence of extrusion, reduction of the injected volume, or abnormalities in the adjacent tissues. Blood levels of CK and LDH were normal and similar in all groups. ALP levels were significantly lower in G2 than in G1 and G3. The systemic organs were normal on histological examination in the 3 groups evaluated. Microscopically, the polyethylene gel was surrounded by a thin pseudocapsule formation and minimal inflammatory cell response, which decreased from G1 to G2. Conclusion: The subcutaneous injection of polyethylene gel in rats elicited minimal local inflammatory response and no systemic side effects. Copyright © 2008 Informa Healthcare USA, Inc.

As funções do grupo de renormalização no modelo com auto-interação quártica fermiônica

Modelos com interações quárticas fermiônicas tem sido estudadas para clarificar aspectos conceituais e possíveis aplicações em teoria quântica de campos. Neste trabalho apresentamos a estrutura do grupo de renormalização no modelo de Nambu-Jona-Lasinio até a ordem de 1-loop. O modelo é não renormalizável perturbativamente, no sentido usual de contagem de potência, mas é tratado como uma teoria efetiva, válida numa escala de energia onde p << ^, sendo p o momento externo do loop e ^ um parâmetro de escala de massa que caracteriza o acoplamento do vértice não renormalizável. Esclarecemos a estrutura tensorial dos vértices de interação e calculamos as funções do grupo de renormalização. A análise dos pontos fixos da teoria também é apresentada e discutida usando o formalismo de redução das constantes de acoplamento proposto por Zimmermann. Encontramos a baixas eneergias a origem como ponto fixo infravermelho estável e um ponto fixo não trivial ultravioleta estável, indicando a consistência perturbativa se o momento é pequeno.

Sobre o discurso político

Procura-se aqui difundir uma proposta de análise do discurso político elaborada pelo germanista Hans Dieter Zimmermann. Partindo do pressuposto de que é necessário observar o objetivo do discurso político, o autor oferece um esquema que permite dividir tais discursos segundo as perspectivas da superestimação, da subestimação ou da conciliação, construídas por meio de um conjunto de figuras retóricas que cataloga.

Composition and Activity against Oral Pathogens of the Essential Oil of Melampodium divaricatum (Rich.) DC.

The chemical composition of the essential oil isolated from the aerial parts of Melampodium divaricatum (Rich.) DC. (Asteraceae) was characterized by GC-FID and GC/MS analyses. (E)-Caryophyllene (56.0%), germacrene D (12.7%), and bicyclogermacrene (9.2%) were identified as the major oil components. The antimicrobial activity of the oil against seven standard strains of oral pathogens from the American Type Culture Collection (ATCC) was evaluated by determining minimum inhibitory concentrations (MICs) using the microdilution method. MIC Values below 100 mu g/ml were obtained against Streptococcus sobrinus (90 mu g/ml), Lactobacillus casei (30 mu g/ml), S. mutans (20 mu g/ml), and S. mitis (18 mu g/ml). In contrast, the MIC values of the major oil compound (E)-caryophyllene were higher than 400 mu g/ml against all pathogens, suggesting that the activity of the oil might depend on minor oil components and/or on synergistic effects. The M. divaricatum essential oil is a promising agent to include in anticariogenic oral rinse formulations for the control of oral pathogens.
