Electron Beam Dose and PMMA Thickness Dependent Circularity and Diameter Analysis of Au Nanodots
Authors: Kuruoğlu Furkan , Yavuzçetin Özgür , Erol Ayşe
Published: November 2018

Background:

The electrical and optical properties of nanoparticle-based devices depend on
the shape, dimension and uniformity of these particles.

Methods:

In this work, we fabricated ordered Au nanodots using electron beam lithography and thermal
evaporation. Au nanodot diameter and circularity varied with a changed exposure dose and resist
thickness. Electron beam dose ranged from 5 fC to 200 fC for single dot patterns. Commonly used
PMMA thin films of thicknesses 60 nm and 100 nm coated samples were used for investigating the
resist thickness dependency with varying dose exposure.

Results:

The analyses of patterns show that the diameter and circularity of the Au nanodots ranged
from smaller to larger diameters and from lower to higher circularities with increasing dose and resist
thickness.

Conclusion:

The distributions of the nanodot diameter began to show Gaussian behavior at larger
electron doses. Besides, single circularity value became dominant up to the medium doses and then a
homogeneous distribution was observed with the increasing dose.

Research Progress of Exogenous Plant MiRNAs in Cross-Kingdom Regulation
Authors: Zhang Hao , Zhan Mengping , Chang Haowu , Song Shizeng , Zhang Chunhe , Liu Yuanning
Published: November 2018

Background:

Studies have shown that exogenous miRNAs have cross-kingdom regulatory effects on bacteria and viruses, but whether exogenous plant miRNAs are stable in human body or participate in cross-kingdom regulation is still controversial.

Objective:

This study aims to propose a new method for the presence and cross-kingdom regulation pathway of exogenous Plant miRNA, which combines biological calculations and biological experiments.

Method:

Based on the high-throughput sequencing data of human health tissue, the tissue specificity model of exogenous plant miRNA can be constructed and the absorption characteristics will be excavated and analyzed. Then screening the exogenous Plant miRNA based on the crosskingdom regulation model of plant-human miRNA, and isotope labeling can be used to verify the presence and regulation pathway of exogenous plant miRNA.

Results:

Only based on a comprehensive analysis to human high-throughput miRNA data, establishing cross-kingdom regulation model and designing effective biological experiments, can we reveal the existence, access pathways and regulation of exogenous plant miRNAs.

Conclusion:

Here, we reviewed the most recent advances in the presence and pathway of exogenous plant miRNAs into human and their cross-kingdom regulation.
Club Drugs and Rave Parties: A Pilot Study on Synthetic Drug Consumption Styles in a Sample of Young Italian Ravers
Authors: Biolcati Roberta , Mancini Giacomo
Published: November 2018

Introduction:

So-called club drugs, psychoactive substances by definition related to rave and private parties culture, have a strong social impact in terms of health risks, especially for their spread among adolescents and young adults. In addition, polydrug use is a common pattern of consumption in some subcultures, such as the ravers culture. This study explores characteristics, consumption profiles, contexts of use, motives, and levels of satisfaction with life in a sample of synthetic/hallucinogenic substance users.

Methods:

We administered an ad hoc questionnaire to 37 Italian participants (62.2% males) recruited through several rave events in the city of Bologna.

Results/ Conclusions:

The results showed that consumers choose substances belonging to the same “family,” such as methamphetamines (MDMA and speed) and psychedelic substances (ketamine and LSD), for specific and contextual motives. The findings are discussed in light of the target sample’s socioeconomic conditions, consumer profiles, features of the rave context, and dissatisfaction with some areas of life.
SOOP: A Swarm-Optimized Opinion Prediction Model for S-Health Governance
Authors: Kumar Akshi , Sharma Abhilasha
Published: November 2018

Background:

To realize a viable and resilient smart city-smart nation scenario, “peoplecentric”
strategic technology components are imperative to eventually create smart outcomes for citizens.
Smart health is one such domain where the government is putting incessant effort to ensure
social well-being and sustainability. Contemplation of public opinion plays a very significant role in
the process of government policy evaluation. The current affordable, ubiquitous generation of Web
provides substantial amount of opinionated social big data which facilitates data-driven decision
making. But determining the polarity of short-text, a.k.a. sentiment is hard owing to the noisy, ambiguous
and heterogeneous use of natural language.

Objective:

A novel health governance framework using a Swarm Optimized Opinion Prediction
model, SOOP Model is proposed to capture netizen views on government policies and figure out the
inclination of public about the campaign. The model is investigated for the sentiment classification
task on tweets pertaining to ‘Poshan Abhiyaan’, one of the latest healthcare policy, launched by the
Government of India to address the issues related to malnutrition in women and children.

Methods:

The conventional feature extraction using TF-IDF (Term Frequency-Inverse Document
Frequency) is done on the pre-processed dataset. Subsequently, Binary bat algorithm, a swarm-based
optimal feature selection method is used to improve the sentiment classifier’s performance.

Results:

The empirical analysis validates that the proposed implementation of the meta-heuristic algorithm
for feature subset selection outperforms the baseline supervised learning algorithms with an
average 9.4% improvement in accuracy and approximately 39% average reduction in features.

Conclusion:

The proposed SOOP Model as a policy evaluation strategy within the healthcare setting
empowers various stakeholders and enhances their socio-economic environment.
Grey Relational Analysis based Keypoints Selection in Bag-of-Features for Histopathological Image Classification
Authors: Pal Raju , Saraswat Mukesh
Published: November 2018

Background:

With the expeditious development of current medical imaging technology,
the availability of histopathological images has been increased in a large number. Hence, histopathological
image classification and annotation have emerged as the prime research fields in the pathological
diagnosis and clinical practices. Several methods are available for the automation of image
classification.

Methods:

Recently, the bag-of-features appeared as a successful histopathological image classification
method. However, all the extracted keypoints in bag-of-features are not relevant and generally
have very high dimensions, which degrade the performance of a classifier. Therefore, this paper introduces
a new Grey relational analysis-based bag-of-features method to search the relevant keypoints.

Results:

The efficacy of the proposed method has been analyzed on animal diagnostics lab histopathological
image datasets having healthy and inflamed images of three organs. The average
accuracy of the proposed method is 88.3%, which is the highest among other state-of-the-art methods.

Conclusion:

This paper introduced a new Grey relational analysis-based bag-of-features which
improves the efficiency of vector quantization step of the standard bag-of-features method. The
method used Grey relational analysis for similarity measure in vector quantization method of bag-offeatures.
The proposed method has been validated in terms of precision, recall, G-mean, F1 score,
and radar charts on three datasets, Kidney, Lung, and Spleen of ADL histopathological images.
Ring-Opening Polymerization of L-lactide Initiated by Samarium(III) Acetate
Authors: Ramírez Jesús Miguel Contreras , Medina Dimas , López-Carrasquero Francisco , Contreras Ricardo Rafael
Published: November 2018

Background:

The synthesis of the aliphatic polyesters obtained by the ring opening
polymerization has been achieved using as initiators a large amount of organometallic compounds
derivative from: Alkali metals, alkaline earth metals, transition metals and lanthanide metals. Of all
these compounds, the lanthanide derivatives have acquired great importance in the synthesis of aliphatic
polyesters, since these show a greater catalytic activity and also can provide polymer with
characteristics that will be very useful in the design of biomaterials.

Objective:

It was proposed the synthesis of poly(L-lactida) (PL-LA) through a ring opening polymerization
process of L-lactide initiated with samarium(III) acetate (Sm(OAc)3) under solvent-free melt
conditions. The influence of different parameters of reaction, such as temperature, time, molar ratio
monomer to initiator, on typical variables of polymers, e.g., conversion, dispersity, and molar mass,
were analyzed.

Methods:

All polymerizations were carried out under solvent-free melt conditions in ampoules-like
flasks, equipped with a magnetic stirrer. The obtained polyesters were characterized by size exclusion
chromatography (SEC) and 1H-NMR.

Results:

The Sm(OAc)3 induces the polymerization of L-LA at high conversion, and produce polyesters
with number-average molecular weights of 1.00 x 103 to 30.00 x 103 Dalton. The 1H-NMR analysis
indicates a typical polymerization mechanism of coordination-insertion, with a breakdown of the
acyl-oxygen bond of the L-LA.

Conclusion:

Sm(OAc)3 was an effective initiator for the ring-opening polymerization of L-LA. SEC
chromatography showed that, at high temperatures and prolonged reaction times, the molar mass of
the polyester decreases, which is associated with the transesterification collateral reactions that occur
during the polymerization process.
Dental Students’ Evaluations of Practice Management Education and Interest in Business‐Related Training: Exploring Attitudes Towards DDS/DMD‐MBA Programs
Authors: Han Jae Young , Paron Thomas , Huetter Marc , Murdoch-Kinch Carol Anne , Inglehart Marita R.
Published: November 2018

Being well prepared for a competitive business environment is crucial for future dentists. The aims of this study were to assess dental students’ satisfaction with their practice management education, their current and future interest in business‐related education and attending a DDS/DMD‐MBA program, and the relationship between their demographic and other characteristics and their business education‐related responses. The study, conducted in 2016 and 2017, surveyed students in all four years at the authors’ home school and at other schools that did not have a DDS/DMD‐MBA program. At the home school, 273 students responded (response rate 63%); and 341 students from 11 of the 51 U.S. dental schools without a DDS/DMD‐MBA program responded (respondents were from 21% of schools invited; the response rate of those students could not be calculated). The responding students disagreed that their school adequately prepared them for the business aspects of dentistry (mean=2.42 on a scale from 1=disagree strongly to 5=agree strongly). Large majorities agreed/strongly agreed that dentistry is a career that requires a certain amount of business acumen (95%) and that they were very interested in learning about business (85%). A total of 68% agreed/strongly agreed that their school should offer a dual DDS/DMD‐MBA degree and 63% that they would consider enrolling in such a program. The more advanced the respondents were, the less satisfied they were with their practice management education (r=−0.20; p<0.001). Female respondents were less interested in business‐related education (r=−0.20; p<0.001) and less likely to consider a DDS/DMD‐MBA program than the males. Respondents planning to own a dental practice were more interested in additional current business education (r=0.22; p<0.001) and in future business education (r=0.15; p<0.001) than those without that plan. These results showed that a significant percentage of these dental students were interested in a DDS/DMD‐MBA program. The male students and students who planned to own a practice were more interested in business education than the female students and students who did not plan to own their own practice.
Education About Dental Erosion in U.S. and Canadian Dental Schools
Authors: Ngoc Caroline Nguyen , Donovan Terry E.
Published: November 2018

Dental erosion (DE) is a well‐accepted multifactorial form of tooth wear involving acids. Due to its irreversible nature, recognizing the early signs is important to develop appropriate preventive strategies. However, its place in dental curricula remains unclear. Consensus has not been established regarding the integration of erosive tooth wear into core cariology curricula in North America. The extent to which DE is taught is questionable since etiology, risk assessment, and management are not all the same as for dental caries. The aim of this study was to survey U.S. and Canadian dental schools regarding their teaching of DE. Email invitations were sent to deans, chairs, and selected faculty members at all 76 U.S. and Canadian dental schools in 2016, asking them to either respond or forward the survey‐link provided to the appropriate person in their school. Responses from the same school were combined for analysis. Respondents from 59 schools (77.6% response rate) responded to the survey, and all of them confirmed the inclusion of DE in their curricula. However, only 15.3% of respondents identified correctly all the clinical signs of DE. Although management through behavioral intervention was prioritized, diet analysis was often not a clinical requirement, and 45.8% of respondents did not teach any type of tooth wear index for monitoring. This study concluded that DE has a place in dental curricula, but whether this topic is adequately covered is questionable. There is a need to establish clearer topics and requirements emphasizing the diagnosis and management of DE, potentially in cariology curricula.
Renewable Energy in the International Arena: Legal Aspects and Cooperation
Authors: Citelli Marco , Barassi Marco , Belykh Ksenia
Published: November 2018

This article aims at investigating the relevant aspects of international law and cooperation in the field of renewable energy. Part I provides an overview of the multiple soft law developments within and outside the UN framework as well as an assessment of a chosen set of extant treaty obligations either fostering or potentially constraining the development of the renewable energy sector. In light of these norms, Part II analyses a series of recent cases and international disputes triggered by non-environmental interests and rights allegedly impaired by the implementation of certain renewable energy-related plans and projects. In particular, this section considers the compatibility of renewable energy development with extant norms in the areas of human rights (ECHR), procedural environmental rights (Aarhus Convention) and international trade law (WTO). Despite the scarcity of binding norms on renewable energy generation and the persistence of various factors leading to disputes, global cooperation in the field of renewable energy is gaining momentum. Starting with an overview on CDM renewable energy projects under the Kyoto Protocol, Part III then shifts to the latest developments in renewable energy cooperation prompted respectively by the creation of the International Renewable Energy Agency (IRENA) and by the growing number of transnational private partnerships operating in the field of renewables.
Using Private Contracts for Climate Change Mitigation
Authors: Peterková Mitkidis Kateřina
Published: November 2018

Regulation of climate change is caught up in a stalemate. Differences between developed and developing countries prevent reaching an international agreement. Transnational private regulation has unclear legitimacy, effectiveness and enforcement. National efforts are valuable, but their limited geographical reach creates incentives for companies to outsource environmentally heavy activities to countries with weaker regimes, the socalled “carbon leakage” effect. As a result the carbon emissions among international supply chains amount to multiple yearly emissions of some developed countries. This gap needs to be closed if we aim for effective global solutions to climate change. The majority of scholars agree that no single regulatory tool alone can remedy the situation, but that a combination of public and private, mandatory and voluntary regimes is necessary. The author proposes that supply chain contracts are the missing piece in the international climate change regulatory matrix. The article discusses why, despite their potential, supply chain contracts have hitherto experienced only little attention and why they can be successful where other regulation fails. It concludes that the potential of private contracting should be triggered by adequate regulation.
Balancing The State’s Right To Regulate with Foreign Investment Protection: A Perspective Considering Investment Disputes in the South American Region
Authors: Gwynn Maria A.
Published: November 2018

Some of the challenges in reforming the international investment framework have derived from investor-state disputes, where host states have been sued for environmental or health regulations. Clauses regarding investor-state dispute settlement mechanisms have been therefore improved in modern investment treaties. However, most developing countries, which tend to be most of the host countries to investments, still have Bilateral Investment Treaties from the 1990s where investor-state dispute settlement clauses remain unchanged. This paper analyses different strategies that host countries are taking in light of these challenges. These are particularly noteworthy in the South American region, where one can identify three different approaches concerning the international investment framework. Reflecting on these approaches, the paper addresses the relevance of the multilateral efforts to reform the framework as a way forward, and a more promising strategy, towards the aim of balancing the states and foreign investors’ interests.
Corporate Liability and Compensation Following the Deepwater Horizon Oil Spill: Is There a Need for an International Regime?
Authors: Theodotou Stephanie
Published: November 2018

The purpose of this article is to assess the effectiveness of the current fragmented legal framework regarding corporate liability and compensation following oil spills from offshore installations, in light of the Deepwater Horizon oil spill. It evaluates whether Deepwater Horizon has signalled the need to adopt a uniform international regime, which will regulate compensation and liability concerning oil spills from offshore oil installations. The first part of this article provides the factual background of the Deepwater Horizon oil spill, with an emphasis on the corporate liability and compensation issues that arose in this incident and the response by the U.S. Government. The second part evaluates the effectiveness of the current three-tiered system of compensation in the oil tanker industry, as well as the supplementary voluntary agreements thereto, and assesses whether this legal framework could be adopted to the regime governing oil spills from offshore oil installations. It notes the stark contrast between oil spills from oil tankers and oil spills from offshore oil installations, in that an oil tanker’s maximum storage capacity is known which makes the risk of potential spillage calculable. In contrast, it is impossible to make such a calculation for oil spills resulting from offshore oil installations since, although the storage capacity of the installation is defined when it is constructed, the amount of oil that can be spilled directly from the well drilled into the marine environment is unpredictable. The third part discusses the prospects for adopting an international civil liability and compensation regime governing oil spills from offshore installations, with reference to several international and regional attempts that have been made to establish an efficient regime and provides proposals for an efficient and effective international regime.
Technology Acquisitions: A Process Perspective on Search, Selection and Implementation
Authors: Bobelyn Annelies S. A.
Published: November 2018

Technology acquisitions have become an important external source of innovation. But notwithstanding the abundant literature on the topic, relatively little is known about the acquisition process itself and how it impacts acquisition performance. Some papers have used a process perspective as point of departure, but these studies focus at one component of the acquisition process and neglect to question how these different process components interact to influence acquisition performance. To address this gap, we carefully scrutinize each process component for its influence on the subsequent acquisition stages and performance. Using a case study design, we find that the decisions and managerial actions taken in the search and selection phase have an important impact on the success of implementation. We identify search and involvement of the client department as crucial mechanisms in the acquisition process and reveal their implications for the structure and composition of the team managing the acquisition.

Authors: P Kishore , Meghana G , Reddy B. Pratap , Raghavaiah K V , Kumar D Sudheer
Published: November 2018

ABSTRACT

Chemotherapy and radiation are one of the important components of treatment for many cancers. Anti-neoplastic agents are used with caution due to their high toxicity and narrow therapeutic window. Studies describing pattern of adverse drug reactions in cancer chemotherapy and radiation therapy patients are less in India. This study aims to evaluate the pattern of ADR’s due to cancer chemotherapy and radiation therapy in hospitalized patients and to assess the causality and severity of these reactions in Telangana state, India. This was a prospective observational study conducted in a private hospital in Telangana region from January to august. Two thousand three hundred and forty two ADR’s were recorded from 254 patients. Most common ADR’s were vomiting (10.7 %), nausea (10.7 %) and fatigue (10.7 %). Majority of the ADR’s (53.5 %) were affecting the Gastro-intestinal system. Naranjo scale for causality assessment showed 54.3 % of the reaction to be “definite”, 36.8 % to be “probable”. Modified Hartwig and Siegel scale for severity showed most reaction (84.1 %) to be of “moderate level”, while 13.3 % of reactions were of “mild level”. There is an immediate need to create awareness among health care professionals regarding the importance of the pharmacovigilance system. Use of preventive measures is to be enhanced in order to reduce the incidence and severity of ADR’s. This study showed most ADR’s are preventable with effective ADR monitoring.

Keywords: Adverse drug reaction (ADR), ADR monitoring, Pharmacovigilance, chemotherapy, radiation therapy.
BIOANALYTICAL METHOD DEVELOPMENT AND VALIDATION FOR THE ESTIMATION OF LEVOCETIRIZINE IN BLOOD PLASMA BY USING RP-HPLC
Authors: Khatri Sweety
Published: November 2018

A rapid, selective, precise and sensitive reverse phase high-performance liquid chromatography method was developed for the quantitative estimation of Levocetirizine Dihydrochloride (LD) in human plasma and pharmaceutical dosage form. Extraction of drug from plasma was done by employing optimized liquid-liquid extraction procedure. The sample was analyzed using acetonitrile: methanol: 20mM ammonium acetate buffer pH-5 (25:55:20 % v/v/v) as mobile phase. Chromatographic separation was achieved on Thermo C-18 column (4.6 x 250mm, 5μ particle size) as stationary phase using isocratic elution (at a flow rate of 1 ml/min). The peak was detected using UV-PDA detector set at 232 nm and the total time for a chromatographic separation was 8 min. The calibration curve obtained was linear (r2= 0.9998) over the concentration range of 2-10 μg/ml. Method was validated for precision, robustness and recovery. The limit of detection and limit of quantitation was 0.0057 and 0.174 µg/ml respectively. There was no significant difference between the amount of drug spiked in plasma and the amount recovered and plasma did not interfere in estimation. Thus, the proposed method is suitable for the analysis of LD in tablet dosage forms and human plasma.

Fate of the Antegrade Ureteric Stent
Authors: Raju Jerry A. , George Cherian , Patel Prashant , Liu Samson
Published: November 2018

Introduction

Antegrade stents are commonly used to relieve malignant and benign ureteric obstruction. However, follow up of these patients often involves several specialties and the potential for delayed management and forgotten stents. This observational study reviews indications and outcomes of antegrade stent procedures at one university hospital to provide prognostic and quality improvement data.

Patients and Methods

A retrospective analysis of 152 antegrade stent procedures in 142 patients over a 27-month period was performed. Cohorts were studied according to underlying pathology, referring specialty and intended duration of stent placement. Measured outcomes were time to stent removal or stent exchange, death, forgotten stents and complications.

Results

The overall technical success rate of antegrade stent insertion was 98%. Follow-up data was available for 145 successful procedures in 138 patients. Malignancy (47%) and stone disease (35%) were the commonest indications. Overall, 43 patients (31%) died over a median follow up period of 2.2 years. 29 of 64 patients (45%) with malignancy died with stents in situ after a median interval of 3.5 months. Malignancy and unclear intended duration of stent placement were predictors of death with a stent in situ. Twelve patients (9%) had forgotten stents and a strong association with gynaecological malignancy was noted, which is felt to represent inadequate follow up of patients with non-urological pathology. Complications were reported in thirteen patients (9%), including ten cases of heavy stent encrustation and one malpositioned stent.

Conclusions

Prognostic factors should be considered in the management of patients stented for malignant obstruction, which is usually a marker of advanced disease. The hazards of inadequate follow up are highlighted, causing delays in stent removal and exchange, or the forgotten stent. Interventions are described to minimize these risks.

O Cruzeiro: uma revista síntese de uma época da história da imprensa brasileira
Authors: Barbosa Marialva
Published: November 2018

Dois movimentos concomitantes caracterizam a imprensa do Rio de Janeiro na década de 1920: o aparecimento de um jornalismo eminentemente sensacional e o surgimento dos primeiros conglomerados de imprensa, representados pelos Diários Associados. Espelhando de certa forma o chamado pensamento conservador, os jornais da cidade adquirem características peculiares. Para uns o sensacional é a grande arma de conquista do público. Para outros, a ação política seria fundamental. Em meio a esses dois movimentos, o grupo dos Diários Associados lançam aquela que seria a principal revista ilustrada brasileira do século XX : O Cruzeiro. Este texto - parte de uma ampla pesquisa, financiada pelo CNPq, que reconta a história da imprensa no Rio de Janeiro a partir dos indícios deixados pela múltiplas falas do público - faz uma breve reflexão sobre a história inicial desse periódico de um ponto de vista particular : o olhar do leitor. Num primeiro momento, reproduz as estratégias editoriais e mercadológicas quando do lançamento da publicação em novembro de 1928. Como segundo movimento, descreve as práticas jornalísticas adotadas na década seguinte, que pode ser considerado o momento de consolidação da revista no cenário nacional brasileiro. Até o momento, remontamos a história da imprensa do Rio de Janeiro durante os cinquenta primeiros anos do século XX, estando agora exatamente na metade. A partir dessa análise inicial escrevemos o livro “Desvendando a face do público: 50 anos de imprensa do Rio pelo olhar do leitor”, que está sendo editado com financiamento da Fundação de Amparo à Pesquisa do Rio de Janeiro (FAPERJ).

Conceitos, armadilhas, olhares: apontamentos metodológicos para a consolidação de um campo transdisciplinar
Authors: Barbosa Marialva
Published: November 2018

Texto construído fundamentalmente para refletir sobre a questão teórica e metodológica, o texto aprofunda reflexões realizadas anteriormente num percurso cuja preocupação central é a definição epistemológica do campo da comunicação. Nesse sentido, procura mostrar como é central para o reconhecimento da comunicação como campo consolidado – perante um universo maior, ou seja, a comunidade científica – a difusão de uma espécie de discurso em “uníssono” que fale de problemáticas comuns, teorias que se complementem e metodologias que marquem a especificidade do lugar de onde se fala. Nesse sentido, tão importante quanto teorias da comunicação, seria o desenvolvimento de metodologias da comunicação, que não se confundiram com procedimentos de análises de outros campos, criando um olhar particular próprio desse lugar: o campo da comunicação.
Recepção da comunicação no mundo do trabalho: uma crítica à ação comunicativa
Authors: Figaro Roseli
Published: November 2018

Os resultados da pesquisa de recepção intitulada: Comunicação e Trabalho - Estudo de recepção: o mundo do trabalho como mediação da comunicação levou-nos à reflexão teórica sobre a centralidade da categoria trabalho para a compreensão do que se passa no campo da comunicação. Levou-nos também a discutir a subjetividade a partir de uma perspectiva materialista dialética, buscando compreender como as práticas culturais vivenciadas no mundo do trabalho comportam a contradição: de uma lado, a alienação do sujeito, imposta pelo capital e pela organização da produção, e, de outro, a resistência, na maior parte das vezes, individual, deste sujeito pela manifestação de seu ser genérico.Esta resistência resulta da mobilização dos saberes cotidianos, das práticas profissionais do mundo do trabalho, da cultura particular do grupo, da memória familiar e comunitária, da memória e da experiência das lutas populares e sindicais – aspectos fundamentais para a construção da contra-hegemonia. Além disso, a pesquisa propiciou ainda compreender melhor como a ideologia do neoliberalismo solapou através do slogan do progresso tecnológico e pela via da apologia ao individualismo consumista, o aspecto coletivo, democrático, educador que a comunicação pressupõe para o exercício da cidadania e emancipação do sujeito. Neste sentido, buscaremos avançar teoricamente discutindo a relação entre comunicação/trabalho versus ação comunicativa. Pretendemos com isto destacar que os estudos de recepção contribuem para as teorias de comunicação na medida em que não se deixam apanhar pelo culturalismo particularista que desvincula os grupos societários das mediações que permeiam a todos de uma maneira ainda mais complexa na sociedade globalizada e capitalista.

Resistência ao cisalhamento de nichos em resina composta com técnica direta e indireta.
Authors: Ramiro  Camacho Rodrigues Alexandra
Published: November 2018

A utilização de caninos inferiores, como pilares de Prótese parcial removível (PPR), requer a modificação no contorno dental por acréscimo. O objetivo deste estudo foi determinar a tensão máxima para deslocar nichos em resina composta (RC), confeccionados pela técnica direta e indireta. Foram selecionados 21 caninos inferiores, humanos, hígidos do banco de dentes da Faculdade de Odontologia da UFF, e, em seguida, limpos e asperizados na região do cíngulo. Etiquetas adesivas com perfuração de 6 mm de diâmetro foram fixadas na região asperizada, delimitando a área de trabalho. Os dentes foram separados aleatoriamente em três grupos, segundo a técnica de aplicação da RC. Nos grupos I e II, foi utilizada técnica direta, à mão livre e com auxílio de matriz de poliéster, respectivamente. No grupo III, foi utilizada técnica indireta. O preparo dos descansos  foi realizado com broca diamantada e polido com pontas de borracha. As amostras foram submetidas a termociclagem e ensaio de cisalhamento. Foi realizada,  ainda, inspeção visual  a olho nu e através de estereomicroscópio (20x), para determinar o tipo de fratura dos corpos de prova. O teste de Tukey ao nível de significância  = 0,01 não indicou a existência de diferença estatisticamente significa-tiva (p > 0,01) entre os grupos I e II, entretanto, quando comparados com o grupo III, a diferença foi estatisticamente significativa. As imagens obtidas no estereomicroscópio demonstraram que, em 100% das amostras dos grupos I e III e em 70% do grupo II, as fraturas ocorreram no corpo da resina.Palavras-chave: Nichos – Prótese parcial removível – Resina composta –  Força máxima.
Uso da tomografia computadorizada por feixe cônico na endodontia.
Authors: Accorsi-Mendonça Thais
Published: November 2018

O correto diagnóstico apresenta-se com um marco inicial para o sucesso em Endodontia. Para tal, são unidas informações provindas da anamnese, exames clínicos e complementares. O exame radiográfico, dentre as suas variações, possui limitações por apresentar uma imagem bidimensional de uma estrutura tridimensional. Atualmente, no campo da Imaginolo-gia, a Tomografia Computadorizada por Feixe Cônico (TCFC), também conhecida como Cone Beam, evidencia-se como uma possibilidade de obtenção de imagens tridimensionais, o que atribui maior confiabilidade aos diagnósticos e planejamento operatório. Esta revisão tem por escopo abordar alguns tópicos de interesse em Endodontia e sua correlação com a TCFC.Palavras-chave: Tomografia Computadorizada de Feixe Cônico.  Endodontia.

Análise comparativa do efeito de dentifrício fluoretado infantil na microdureza do esmalte dental : estudo in vitro
Authors: Lopes Coutinho Thereza Christina
Published: November 2018

O objetivo deste estudo foi verificar comparativamente, in vitro, sob ciclagens de pH, a capacidade de remineralização de lesões artificiais de cárie com o uso de dentifrício fluoretado infantil mais vendido no mercado, através da análise da microdureza superficial do esmalte (Microdureza Knoop). Quarenta e cinco blocos de esmalte de terceiros molares humanos inclusos, extraídos por razões clínicas foram divididos em 3 grupos: 1 – Tandy® (1.100 ppmF NaF); 2 – Emoform® (Controle – sem flúor); 3 – Crest® (“Referência” – 1.100 ppmF NaF). A medida da microdureza foi realizada no esmalte dental hígido (K1), após a indução de cáries artificiais (K2) e após as ciclagens de pH (K3). Estas foram realizadas por 14 dias na solução com os dentifrícios, durante 5 minutos, em 3 horários programados (8, 12 e 18h). Os valores de microdureza Knoop (K3) assim como os de remineralização (alfa) foram analisados estatisticamente pelo teste ANOVA e quando encontradas diferenças significativas, pelo teste de Comparações Múltiplas através do método Student-Newman-Keuls. Quanto à microdureza, o teste ANOVA demonstrou diferença estatisticamente significante (P=0.0000202; p<0.0001) entre os grupos: 1 (228.9 KHN); 2 (147.8 KHN) e 3 (254.4 KHN), comprovando a ocorrência de remineralização com o uso dos dentifrícios fluoretados testados. Quanto ao valor alfa, o teste ANOVA também mostrou diferença estatisticamente significante (P=0.0000000116; p<0.0001) entre os grupos e, de acordo com o método Student-Newman-Keuls, os percentuais diferiram significativamente (p<0.05) na seguinte ordem: Crest® (54%) > Tandy® (33%) > Emoform® (-40%), sendo que neste último não ocorreu remineralização. Conclui-se que, o dentifrício infantil utilizado nesta pesquisa foi capaz de remineralizar o esmalte, sendo indicado seu uso para crianças com risco e/ou atividade de cárie.   Palavras-chave: Dentifrício –  Microdureza do esmalte – Fluoreto

RELEVÂNCIA DA UTILIZAÇÃO DO PLASMA RICO EM PLAQUETAS ASSOCIADO AO BIO-OSS® EM LEVANTAMENTO DE SEIO MAXILAR: REVISÃO SISTEMÁTICA
Authors: O. Fernandes Gustavo V.
Published: November 2018

RESUMO O advento da osseointegração e dos implantes dentários revolucionaram o tratamento e a reabilitação protética de pacientes edêntulos totais e parciais. Obstáculos anatômicos tais como o seio maxilar pneumatizado impediam a instalação imediata de implantes. Com o avanço da implantodontia, técnicas cirúrgicas para a reconstrução de rebordos, tais como o levantamento de seio maxilar, foram introduzidas, ampliando as possibilidades de tratamento. Esta técnica consiste no ganho ósseo a partir do assoalho do seio maxilar com a colocação de um material de enxertia. Para melhorar a reparação óssea, diversos estudos avaliaram os efeitos dos fatores de crescimento e de diferenciação tais como PDGF, VEGF, TGF, EGF, entre outros. Estes fatores são produzidos pelas plaquetas. O plasma rico em plaquetas (PRP), um concentrado autógeno de plaquetas humanas, vem sendo utilizado com destaque na prática clínica há mais de 15 anos a fim de otimizar a neoformação óssea quando associado aos enxertos. No entanto, ainda existe uma grande controvérsia acerca de sua eficácia. Assim, o objetivo deste estudo foi realizar a revisão sistemática da literatura sobre a eficácia do PRP associado ao xenoenxerto Bio-Oss® (osso bovino desproteinizado) em cirurgias de levantamento de seio maxilar. A busca com palavras-chaves [(PRP) OR (Platelet-Rich Plasma) AND Sinus Lift) OR (Sinus Lifting) OR (Sinus Augmentation) AND (Bio-Oss)] na base de dados PubMed retornou 189 artigos dos quais inicialmente foram encontrados 9 artigos sobre o tema em questão. Destes, apenas 2 artigos foram enquadrados nos critérios de elegibilidade e foram incluídos para análise final e discussão. Constatou-se que diversos estudos apresentaram falhas metodológicas comprometendo a confiabilidade dos resultados. Nos artigos considerados, observou-se que os resultados são contraditórios. Em uma avaliação de qualidade dos estudos enquadrados para análise, um foi classificado como de baixo risco de viés e o outro foi classificado como de alto risco de viés. Conclui-se que há grande carência de artigos sobre este assunto e que novos estudos clínicos que há grande carência de artigos sobre este assunto que há grande carência de artigos sobre este assunto e que novos estudos clínicos devem ser realizados com metodologias que considerem, por exemplo, randomização dos grupos e cegamento das análises.

O USO DA ADRENALINA E FELIPRESSINA NA ANESTESIA LOCAL ODONTOLÓGICA EM PACIENTES CARDIOPATAS: REVISÃO DA LITERATURA
Authors: Almeida Barros Mourão Carlos Fernando de
Published: November 2018

RESUMO A discussão sobre a utilização ou não dos vasoconstritores em odontologia para pacientes cardiopatas é grande. A presença dos vasoconstritores oferece vantagens, tais como, retardar a absorção de anestésicos locais, diminuir a necessidade de uma quantidade maior do sal anestésico, com isso, reduzindo o risco de toxicidade, proporcionar um maior controle do sangramento e conforto ao paciente. Porém, sua utilização em pacientes com cardiopatias é um pouco controversa para alguns autores. O objetivo do estudo é revisar a literatura sobre a utilização dos dois principais vasoconstritores utilizados na odontologia (Epinefrina/Adrenalina e Felipressina) em pacientes com cardiopatias. Palavras-Chave: Vasoconstritores, Cardiopatias, Anestésicos locais.   ABSTRACT The discussion on the use or not of vasoconstrictors in dentistry for patients with heart disease is great. The presence of the vasoconstrictor offers benefits such as delaying the absorption of local anesthetics, reduce the need for a larger amount of the anesthetic, thereby reducing the risk of toxicity, providing greater control of bleeding and patient comfort. However, the use in patients with heart disease is controversial for some authors. The aim of the study is review the literature on the use of two vasoconstrictors used in dentistry (Epinephrine / Adrenaline and Felypressin) in patients with heart disease. Keywords: Vasoconstrictor Agents, Heart Diseases, Anesthetics.

Atenção básica na alta complexidade : o cuidado em saúde bucal com o paciente hospitalizado
Authors: Ferreira Bello Rachel
Published: November 2018

Os pacientes hospitalizados necessitam tanto de cuidados especializados para os problemas que motivaram sua internação quanto de atenção para manter todo o sistema orgânico em funcionamento a fim de não comprometer o prognóstico. A inclusão de ações de saúde bucal na alta complexidade tem sido recomendada balizada no princípio da integralidade e dos resultados das pesquisas que mostram a interrelação entre as doenças bucais e o comprometimento sistêmico. O objeti-vo  desta pesquisa foi  verificar se os hospitais que participam da rede de assistência do Sistema Único de Saúde na região Centro Sul Fluminense adotam protocolos que incluem ações de saúde bucal para pacientes internados. Como método de co-leta dos dados foi utilizado a entrevista semi-estruturada com profissional da enfermagem, indicado pela instituição pesqui-sada. Os resultados revelaram que apenas 55,5% das instituições hospitalares desenvolvem alguma atividade de saúde bucal, mas, em 100% dos hospitais, inexistem protocolos de cuidados de saúde bucal. Conclusão: há necessidade de uma po-lítica pública indutora da adoção de protocolos de saúde bucal para os pacientes hospitalizados pelas instituições de saúde.Palavras-chave: odontologia; saúde bucal; hospital; paciente internado.
Avaliação da alteração dimensional de moldes de hidrocolóide irreversível submetidos à tècnica de reembasamento.
Authors: De Abreu bastos Malbely Fátima
Published: November 2018

O objetivo deste trabalho foi avaliar as alterações dimensionais de moldes de alginato quando se emprega a técnica de reemba-samento. A partir de um modelo padrão em aço inoxidável, contendo duas marcações, foram realizadas moldagens com Alginato Ezact Kromm (Vigodent) e os modelos de gesso foram confeccionados com o gesso tipo IV Durone (Dentsply). As moldagens foram divididas em 2 grupos: Grupo I – 10 moldagens com alginato sem reembasamento e; Grupo II – 10 moldagens com o algi-nato utilizando o reembasamento. Os modelos de gesso foram confeccionados com espatulação a vácuo e levados ao Microscópio Comparador Mitutoyo para obtenção das medidas que foram comparadas com o modelo padrão de aço inoxidável. Os dados foram submetidos a análise estatística através do teste “t” de Student e obtivemos os seguintes resultados: houve alteração dimensional estatisticamente significante no Grupo II (p<0,05) em comparação com o Grupo I e o modelo padrão. Concluiu-se que não é recomendado a realização da técnica de reembasamento em moldagem com Alginato, devido a alteração dimensional observada. palavras chave: Moldagem
