Published: November 2018

Thrombophilia is a condition of enhanced functionality of the haemostatic system with an increased tendency for thrombosis, and it can be a congenital, acquired, or complex defect. Pregnancy can be the cause of acquired transitory thrombophilia, which may lead to complications if inherited thrombophilia is also present.

The aim of this study was to determine the genetic structure of the population based on the frequency of the gene variants factor V Leiden G1691A, factor II G20210A, methylenetetrahydrofolate reductase C677T, and plasminogen activator inhibitor-1 4G/5G, as well as to investigate the predictive value of these gene variants in repeated miscarriages.

The study included 87 female patients from Central Serbia with an average age of 32.7±4.5 years with inherited thrombophilia and previous miscarriages, with or without intrauterine foetal death. The exclusion criteria included the existence of gynaecological and infectious aetiology and the deficit of factors important for the coagulation process.

The resulting genotypes were in Hardy-Weinberg equilibrium. The frequency of genotypes with mutated alleles was significantly higher in this group of patients than in the control group for all variants except factor II G20210A. The most commonly mutated alleles were the plasminogen activator inhibitor-1 4G allele (0.61) and methylenetetrahydrofolate reductase T allele (0.47). Double mutation of plasminogen activator inhibitor-1 4G/5G and methylenetetrahydrofolate reductase C677T was dominant in patients with recurrent pregnancy loss (46.15%).

The presence of a combination of genetic variants of the plasminogen activator inhibitor-1 4G/5G and methylenetetrahydrofolate reductase C677T is a significant predictor of spontaneous abortions in women with inherited thrombophilia in Central Serbia.
Energy management based on fractional open circuit and P-SSHI techniques for piezoelectric energy harvesting
Authors: Zouari Manel , Naifar Slim , Bouattour Ghada , Derbel Nabil , Kanoun Olfa
Published: November 2018

Self-powered energy management circuits make energy harvesting converters more efficient and more reliable. This paper presents an improvement of a Maximum Power Point Tracking (MPPT) technique applied on a Parallel Synchronized Switch Harvesting on Inductor (P-SSHI) technique for piezoelectric vibration converters. The aims are to detect the unstable vibrational state, optimize the output voltage and maximize the output power of the piezoelectric transducer.

First, the P-SSHI technique is implemented without an MPPT technique. Then, an MPPT technique based on Fractional Open Circuit (FOC) voltage method is implemented. An improvement of the FOC method is proposed to enhance the capability of the Piezoelectric Energy Harvesting (PEH) system. The comparison between different simulation results shows that by using the same input parameters, the maximum efficiency for the PEH system based on the P-SSHI technique implemented without MPPT is 8.82 % whereas the maximum efficiency of the system based on the (FOC) voltage MPPT method is 13.77 %. A significant improvement of the PEH system is obtained by using the modified (FOC) method, where the efficiency reached 24.59 %.
Dual Fabry–Pérot Interferometric Carbon Monoxide Sensor Based on the PANI/Co3O4 Sensitive Membrane-Coated Fibre Tip
Authors: Peng Jin , Feng Wenlin , Yang Xiaozhan , Huang Guojia , Liu Shaodian
Published: November 2018

A novel dual Fabry–Pérot (F-P) interferometric carbon monoxide gas sensor based on polyaniline/Co3O4 (PANI/Co3O4) sensing film coated on the optical fibre end face is proposed and fabricated. Its structure is composed of standard single-mode-fibre (SMF), endlessly photonic crystal fibre (EPCF), and PANI/Co3O4 sensing membrane (PCSM). Therefore, they form three F-P reflectors, the reflector between SMF and EPCF, that between EPCF and PCSM, and interface between PCSM and air. So, the dual F-P interferometer is achieved. The results show that in the range of 0–70 ppm, the interference spectra appear red shift with the increasing carbon monoxide concentration. In addition, the high sensitivity of 21.61 pm/ppm, the excellent linear relationship (R
2 = 0.98476), and high selectivity for carbon monoxide are achieved. The response and recovery time are 35 and 84 s, respectively. The sensor has the advantages of high sensitivity, strong selectivity, low cost, and simple structure and is suitable for sensitive detection of trace carbon monoxide gas.
The Thermodynamic and Binding Studies of Hg+2 Ions with Egg Protein by Polarographic and pH Metric Techniques
Authors: Acharya Shveta , Sharma Arun Kumar
Published: November 2018

The binding of mercury (II) ion has been studied with egg protein at different pH values and temperatures by the polarographic technique. The binding data were found to be pH and temperature dependent. The intrinsic association constants (k) and the number of binding sites (n) were calculated from Scatchard plots and found tobe at the maximum at lower pH and at lower temperatures. The free energy change (ΔG°) of the combining sites were least at the higher pH and highest at the low pH; therefore, a lower temperature and lower pH offered more sites in the protein molecule for interaction with mercury (II) ions. Statistical effects seem to be more significant at lower mercury (II) ion concentrations, while at higher concentrations electrostatic effects and heterogeneity of sites are more significant.
The Making of Islamist-inspired Terrorism and It’s Counter-terrorism in Indonesia
Authors: Arrobi Mohammad Zaki
Published: November 2018

The study attempts to uncover the making of Islamist-inspired terrorism and its state-led counter-terrorism responses in the modern history of Indonesia. It argues that Islamist-inspired terrorism and its counter-terrorism have been inextricably linked in complex ways within political and historical contexts. Instead of regarding Islamist-inspired terrorism and counter-terrorism as separated and unrelated entities, or perceiving the latter as just response to the former, it suggests that they have been intertwined and shaped each other throughout Indonesia’s modern history. By discussing Islamist-inspired terrorism in the three Indonesian historical periods, namely the resurgence of Darul Islam during 1940-60s, the re-emergence of Darul Islam networks and its series of terrorist attacks in 1980s, and  the Jemaah Islamiyah-related terrorist activities in the 2000s as illustrative cases, the study has delineated the ways in which Islamist-inspired terrorism and its state-led counter-terrorism have been bound up within particular political, historical, and sociological context. In addition to that, the study also reveals that both Islamist-inspired terrorism and its state-led counter-terrorism have been shaped by the dynamic interplay of local, national, and global contexts.
Political Rights of the Citizen in the 2014 Election and the Democracy Index in West Java: The Importance to Strengthen the Accessibilities
Authors: Sahid Asep Abdul , Bin Shahruddin Mohd. Solahuddin
Published: November 2018

Political rights of citizen are an important aspect of Indonesian Democracy Index (IDI). However, in the 2014 Election, this aspect, particularly IDI of West Java, showed the lowest number. One of the efforts have been made by Election organizers to fulfill the political rights of citizen is to make accessibility as the principle of Election through Election Commission Regulation (PKPU). This study addresses why the aspect of the fulfillment of political rights of citizen is low in IDI; and how the principle of accessibility in to fulfill political rights of citizen is being implemented. The corpus of this study is document of IDI West Java Province and information of online media. The results indicate that; first, the implementation of the fulfillment of the political rights of citizen in the 2014 Election in West Java had a number of obstacles, namely the regulation of the accessibility principle is still limited; the lack of data of persons with disabilities; and the weakness of Election organizers concerning voters with disabilities. And secondly, efforts to implement the principle of accessibility by Election organizers are mostly concentrated in the election period implementation process, while the implementation process of the pre-election and post-election periods tends to be ignored.
‘Is Ethnicity the Root of all Evil?’ Engaging Macro and Micro Analysis of Ethnic Violence in Post New-order Indonesia
Authors: Zein Rizqy Amelia
Published: November 2018

In this theoretical review, the author examines intergroup conflicts and genocides in post New-Order Indonesia as the manifestation of politicised nationalism by employing several theoretical approaches. The theoretical review starts from combining micro (social-psychological approach) and macro perspectives (sociological and political approach) to answer these following questions; (a) how do we explain intragroup conflicts and genocides, especially in post New-Order Indonesia, as the consequences of nationalism’s existence? (b) In what circumstances are intergroup conflict, or in the most extreme case; genocide, likely to occur? Thus, the theoretical review is structured into four parts; addressing the problem of intergroup conflict and genocide as well as emphasising its importance to be aware of; tracing back the emergence of the nation using Smith and Barthian’s ethno-symbolic approach; narrating the conditions in which allow intergroup conflict arose; and some concluding remarks.
No Ordinary Time: Indigenous Dispossession and Slavery Unwilling to Die
Authors: Lipsitz George
Published: November 2018

The contemporary coalescence of Indigenous and Black peoples as aggrieved, insurgent, and mobilized polities reflects a shared recognition of more than the private, personal, and parochial concerns of members of those groups. The enduring consequences of Indigenous dispossession and what US jurist William O. Douglas aptly described in the 1960s as “the spectacle of slavery unwilling to die” are felt harshly and directly by First Nations and Afro-diasporic people around the globe, but they harm everyone. Racialized capitalism treats the planet and most of its people as mere objects to be manipulated in the pursuit of profits and power. As the system resorts to ever more desperate and dangerous forms of domination and exploitation, aggrieved communities of color see first the very worst that it has to offer. What happens to them today will happen elsewhere tomorrow. Their insurgencies are not pleas to be granted full recognition and rights within the world as it now exists but rather insistent struggles to transform radically a society that they rightly perceive to be decadent and dying. The turmoil of our time is evidence of chickens coming home to roost, of the ways in which the patterns of the past shape the contours of both peril and possibility in the present, and of the need for the world to be at last responsible and accountable for the cumulative costs of displacement, dispossession, slavery, and segregation.
Dismantling White Privilege: The Black Lives Matter Movement and Environmental Justice in Canada
Authors: Teelucksingh Cheryl
Published: November 2018

On August 12, 2017, in Charlottesville, Virginia, alt-right/White supremacy groups and Black Lives Matter (BLM) supporters came face-to-face regarding what to do about public monuments that celebrate key figures from slavery and the Jim Crow era. White supremacists and White nationalists did not hide their racist ideologies as they demanded that their privileged place in history not be erased. The BLM movement, which challenges state-sanctioned anti-Black racism, was ready to confront themes of White discontent and reverse racism, critiques of political correctness, and the assumption that racialized people should know their place and be content to be the subordinate other.It is easy to frame the events in Charlottesville as indicative of US-specific race problems. However, a sense that White spaces should prevail and an ongoing history of anti-Black racism are not unique to the United States. The rise of Canadian activism under the BLM banner also signals a movement to change Canadian forms of institutional racism in policing, education, and the labor market. This article responds to perceptions that the BLM movement has given insufficient attention to environmental concerns (Pellow 2016; Halpern 2017). Drawing on critical race theory as a conceptual tool, this article focuses on the Canadian context as part of the author’s argument in favor of greater collaboration between BLM and the environmental justice (EJ) movement in Canada. This article also engages with the common stereotype that Blacks in Canada have it better than Blacks in the United States.
This Sacred Moment: Listening, Responsibility, and Making Room for Justice
Authors: Beaton Sadie
Published: November 2018

When Ingrid Waldron asked me to create and share a summary of the excellent and juicy presentations and discussion at the symposium titled “Over the Line: A Conversation on Race, Place, and the Environment,” held in Halifax on October 27, 2017, I agreed right away. I’d planned to be at the symposium listening carefully and taking notes anyway. Little did I know that I had agreed to share my “hot take” verbally, in front of everyone, immediately after the final presentation! I’m much more comfortable sharing my thoughts on something after I have mulled it over for a day, a week, or—even better—a few months. The short series of small thoughts in this article are the closest I could come to synthesizing my impressions of the day, in that moment. The result is not comprehensive, but I hope it expresses the vulnerable and hopeful mood I was sensing, along with the appetite for deep resistance and change in the room at the end of a whole day of badass idea-sharing.
Rules and Consequences
Authors: Cash Dave
Published: November 2018

“Every teacher should have a clear set of rules and consequences in their classroom.” “Teachers need to maintain control of their classrooms at all times.” “Students may not show it, but deep down, they all crave structure and order.” In the abstract, it seemed pretty doable. After all, rules and consequences made me feel safe. Why wouldn’t they make my students feel the same way? I soon learned that lots of people really don’t feel the same way about rules and consequences as I had learned to feel when I was young. And, as I have discovered, their resentments are often very well justified.Today, I live in a predominantly Black neighborhood of a predominantly Black city and I teach in a predominantly—and historically—Black school. I belong to a predominantly Black labor union. The culture of New Orleans is rooted in Blackness. I’ve done a lot of work in recent years to understand what my whiteness means in this context. Peers, elders, and students have helped me learn not only what it means to be Black in a racist society but also what it means to be white in a culture built to oppress people of color. As a result, I am increasingly aware of the delicate danger of giving a white teacher authority over Black students. My affinity for rules and consequences weaponizes me in this context. If I am not careful, I have the power to do some real, lasting damage.

Introducción:  Cuando el dolor asociado a deformidad en hallux valgus es el principal síntoma y el tratamiento conservador no es eficaz, está indicada la cirugía. El objetivo de este artículo fue evaluar nuestra experiencia con la técnica mínimamente invasiva y la osteotomía tipo scarf, mediante la escala AOFAS, radiografías con la corrección del ángulo intermetatarsiano, el ángulo metatarsofalángico, la escala Regnauld y los criterios de Reynolds.Materiales y Métodos: Estudio observacional descriptivo de tipo cohorte retrospectiva. Se incluyeron los pies operados mediante las técnicas mínimamente invasiva y tipo scarf. Se revisaron los datos clínicos preoperatorios, y a los 3 y 6 meses de la cirugía, sobre funcionalidad, hallazgos imagenológicos de tres ángulos, y las clasificaciones de Reynolds y Regnauld.Resultados: Se incluyeron 123 pacientes en quienes se realizaron 150 procedimientos: cirugía mínimamente invasiva (44,7%) y tipo scarf (55,3%). La mediana de edad era de 56 años (RIC 42-61), el 88,6% eran mujeres. No hubo diferencias entre el preoperatorio inmediato, y a los 3 y 6 meses para el ángulo intermetatarsiano entre las dos técnicas; sin embargo, el ángulo metatarsofalángico se corrigió (p <0,001) y el puntaje AOFAS fue mejor a los 3 meses con la cirugía mínimamente invasiva (p <0,001).Conclusiones: Ambas técnicas corrigen la deformidad a valores normales. Con la técnica mínimamente invasiva, la corrección fue mayor y el puntaje AOFAS resultó mejor. La incidencia de complicaciones agudas fue similar. Se necesitan ensayos clínicos sobre este tema para confirmar los hallazgos de este estudio.
Enclavado endomedular elástico para el tratamiento de refracturas de antebrazo en niños. [Elastic stable intramedullary nailing for the treatment of forearm refractures in children.]
Authors: Eamara Pablo , Masquijo Julio Javier
Published: November 2018

Introducción: La diáfisis del antebrazo es el sitio más frecuente de refracturas en niños. Estas lesiones suelen ocurrir en el tercio medio o proximal antes del año de la fractura inicial. Hay poca información sobre el tratamiento de este tipo de lesiones. El objetivo de este estudio fue evaluar los resultados y las complicaciones en pacientes con refracturas de antebrazo que requirieron fijación interna con clavos elásticos endomedulares.Materiales y Métodos: Se registró la siguiente información: datos demográficos, mecanismo de lesión, clasificación, tiempo desde la consolidación de la fractura original hasta la refractura, tipo de reducción y tiempo de consolidación. Los resultados fueron evaluados según la escala propuesta por Martus y las complicaciones, con una adaptación de la clasificación de Clavien-Dindo.Resultados: Se evaluaron 17 pacientes (14 varones) con 17 refracturas de antebrazo (15 cerradas y 2 expuestas). La edad era de 11 años (RIC 7, mín.-máx. 5-15). La lesión ocurrió a las 12 semanas de la fractura inicial (RIC 4.7, mín.-máx. 4-28). El 47% requirió reducción abierta. El tiempo de consolidación fue de 8 semanas (RIC 4, mín.-máx. 6-28). El seguimiento fue de 43 meses (RIC 47, mín.-máx. 12-103). Fue posible evaluar clínicamente a 16 pacientes (1 pérdida en el seguimiento). El resultado fue excelente en 15 casos y regular en uno. Un paciente tuvo pérdida del rango de movilidad (15º); uno, retraso de la consolidación (cúbito) y 3 sufrieron una segunda refractura.Conclusiones: La fijación interna con clavos elásticos endomedulares fue una técnica eficaz para tratar las refracturas de antebrazo en niños. Si bien un alto porcentaje necesita reducción abierta, el tiempo de consolidación y la tasa de complicaciones serían similares a los de las fracturas primarias tratadas con la misma técnica.

Published: November 2018

Abstract This work aimed to evaluate the floral and physicochemical characteristics of passion fruits BRS Pérola do Cerrado cultivar (Passiflora setacea D.C.), as well as its relationship with local climatic factors. Peak flowering, time in days of floral appearance until anthesis and until fruits harvest, floral morphometry, time of flower opening and closing, occurrence of natural self-pollination, geitonogamy and floral incompatibility, physicochemical characteristics of fruits and relationship with climatic variables were evaluated. Under the conditions of this study, it was observed that the flowering peak occurred in November and the time of flower opening ranged from 7:21 pm to 8:40 pm throughout the year, probably influenced by daily solar radiation; while the time of flower closing occurred between 6:00 am and 8:00 pm. After closing, flowers showed no recurrence of floral opening. Flowers of Passiflora setacea species BRS Pérola do Cerrado cultivar are self-incompatible and do not allow geitonogamy. Therefore, for fruit formation, cross-pollination is necessary. Regarding fruit setting in the different pollination methods, rates were 34.6% when artificially made and 53.5% in case of natural pollination. Fruits had, on average, longitudinal diameter of 4.9 cm, cross-sectional diameter of 46 mm and fresh mass of 55 g, juice volume of 15.7 ml per fruit, 13.31 ° Brix and total titratable acidity of 1.7 g / 100g ac. citric.

Abstract Objective: To describe head computed tomography (CT) findings in neonates with congenital Zika virus infection confirmed in cerebrospinal fluid. Materials and Methods: This was a study of 16 newborn infants who exhibited abnormal head CT findings during an outbreak of Zika virus infection. Those infants had the following features: brain imaging suggestive of congenital infection; brain calcifications and negative results on tests for other main infectious causes of primary microcephaly, namely toxoplasmosis, cytomegalovirus, rubella, and HIV; positivity for Zika virus on IgM antibody capture enzyme-linked immunosorbent assay in cerebrospinal fluid. Results: Decreased brain volume was observed in 13 (81.2%) of the infants. All of the infants showed cortico-subcortical calcifications, mainly located in the frontal lobe. In 15 neonates (93.7%), ventriculomegaly was observed. Colpocephaly was a common finding, being observed in 10 patients (62.5%). A prominent occipital bone was identified in 9 patients (56.2%). Conclusion: Our study proves that Zika virus infection can cause congenital brain damage, with or without microcephaly. Some predominant head CT findings in neonates with congenital Zika virus infection, although not pathognomonic, are strongly suggestive of a pattern.

RESUMO Objetivo: avaliar os resultados da colecistectomia laparoscópica em idosos comparados com pacientes mais jovens. Métodos: revisamos os prontuários médicos informatizados de todos os pacientes submetidos à colecistectomia laparoscópica para colecistite crônica ou aguda, de 1o de janeiro de 2011 a 31 de março de 2018, em um único hospital de ensino. Os pacientes foram estratificados em dois grupos: idosos (≥60 anos de idade) e mais jovens (<60 anos de idade). Resultados: de 1645 pacientes submetidos à colecistectomia laparoscópica, 1161 (70,3%) eram mais jovens e 484 (29,7%) eram idosos. A taxa de homens foi maior nos idosos (n=185, 38,2%) do que no grupo mais jovem (n=355, 30,6%, p=0,003). Icterícia foi mais comum em idosos do que no grupo mais jovem (p=0,004). A taxa de operação abdominal prévia também foi maior nos idosos (<0,001). A porcentagem de pacientes com escore ASA II, III e IV foi maior no grupo de idosos (p<0,001 no escore II e III e 0,294 no escore IV). O tempo de operação foi maior nos idosos (71,68±31,27) do que no grupo mais jovem (p=0,001). Os seguintes dados perioperatórios foram maiores nos idosos: colecistite aguda (p<0,001), taxa de conversão (p=0,028), complicações pós-operatórias (p=0,042) e mortalidade (p=0,026). Conclusão: o tempo operatório é maior e a taxa de colecistite aguda, conversão para colecistectomia aberta e complicações pós-operatórias são maiores em idosos quando comparados com pacientes mais jovens submetidos à colecistectomia laparoscópica.

La invención del espacio político en América Latina: laicidad y secularización en perspectiva
Authors: Alcalá Felipe Gaytán
Published: November 2018

Resumen: El concepto de laicidad en América Latina se construyó en gran parte como un mecanismo para consolidar los Estados nacionales, con el pasar del tiempo dicho concepto ha sido multívoco cuando no equivoco en muchos sentidos. Lo que es indudable es que ha servido como referencia para la autonomía del espacio político frente a la religión, concretamente frente a las instituciones religiosas. Para la laicidad el tema de lo religioso no es un tema de diversidad cultural sino fundamentalmente político y jurídico. En el presente texto abordaremos los diferentes conceptos de laicidad y sus usos en América Latina, la diferencia categorial con respecto a la secularización atendiendo sus diferencias e intersecciones. Al final analizaremos cómo la laicidad ha gestionado la diversidad religiosa en lo político y en perspectiva comparada presentamos brevemente como se ha gestionado dicha diversidad entre América Latina y Europa.

Published: November 2018

Resumen La cuestión de los vínculos entre religión y política en general, y religiones y el Estado en particular, forma parte de la investigación social a nivel internacional y local. La comprensión de este fenómeno llevó a la propuesta de una serie de categorías clave, como regulación y laicidad, con características particulares en América Latina. En este artículo, proponemos discutir la categoría de laicidad, sus potencialidades y limitaciones para analizar la relación entre el Estado y las religiones a nivel local. Para ello, presentaremos las organizaciones municipales que trabajan con las religiones en la Provincia de Buenos Aires (Argentina), su funcionamiento y las redes que construyen.
Heterossexualidade e homossexualidade: prescrições sobre o uso do corpo das mulheres evangélicas
Authors: Rosas Nina
Published: November 2018

Resumo: Os evangélicos são bem conhecidos por seu recato e pudicícia. Mas, nem por isso, deixam de elaborar prescrições bem específicas sobre como o sexo pode ser vivenciado, contrariando a imagem que deles é feita pelo senso comum. É do conjunto de orientações envolvendo a hetero e a homossexualidade que trata este artigo. A análise traçada evidencia o modo como a religião se põe como recurso pedagógico de construção e reforma do corpo feminino, não apenas monitorando-o e controlando-o, mas produzindo um tipo específico de sexualidade. Os dados foram reunidos principalmente a partir de observação participante, realizada entre os anos 2011-2014, na Igreja Batista da Lagoinha, em Belo Horizonte. Foram acompanhados todos os eventos destinados a mulheres e organizados pela pastora Ana Paula Valadão.

Published: November 2018

Resumo: O artigo analisa o modo como um especialista religioso e sua igreja pentecostal de alcance regional, localizada no município de Campos dos Goytacazes/RJ, constroem uma ressignificação específica da teologia da prosperidade. Embora essa teologia possua um núcleo unificador de concepções e práticas a respeito da relação entre o homem e o divino, o especialista religioso que estudamos, Apóstolo Luciano, promove adaptações e ressignificações dessas concepções e práticas. Este artigo analisa, assim, uma ressignificação da Teologia da Prosperidade operada pelo Apóstolo Luciano, líder da Igreja Semear, ao adaptar suas práticas e concepções para ofertar bens religiosos afinados com o público de membros atuais e potenciais dessa organização.
Os Estados, o sistema-mundo capitalista e o sistema interestatal: uma leitura crítica das contribuições de Immanuel Wallerstein
Authors: ACCO MARCO ANTONIO
Published: November 2018

RESUMO Os Estados nacionais constituem uma das agendas centrais do debate no mundo contemporâneo, uma agenda extensa que gerou importantes abordagens em disputa sobre o ritmo, direção e a profundidade das possíveis transformações dos Estados em curso nas últimas décadas. Este artigo tem por objetivo reconstruir e analisar criticamente os conceitos, atribuições, possibilidades e impasses vividos pelos Estados nacionais encontradas nas formulações de Immanuel Wallerstein. Com este propósito, faremos uma releitura atenta de sua obra, retendo os principais componentes de sua formulação sobre o Estado em suas interações com o sistema mundo capitalista e o sistema interestatal. Parte--se de uma síntese crítica das formulações de Wallerstein sobre sistemas históricos como a unidade de análise correta, as formas históricas desses sistemas, o duplo conceito de capitalismo, de sistema capitalista mundial, de Estado e de sistema interestatal enquanto categorias cruciais de sua abordagem. Tendo por base esses fundamentos, explora-se, então, a análise de Wallerstein sobre o papel dos Estados nacionais nos dias atuais, a crise do sistema mundo que vivemos, assim como as possibilidades e impasses da atuação dos Estados neste contexto. As considerações finais abordam limites e oportunidades legadas por sua desafiadora formulação.
Quem, afinal, apoiou o Plano Collor?
Authors: ANDRADA ALEXANDRE F. S.
Published: November 2018

RESUMO No livro Economia Brasileira Contemporânea, Lavínia Barros de Castro afirma que o Plano Collor “recebeu críticas de todas as partes”, que o “bloqueio dos recursos foi considerado uma inadmissível intervenção estatal”, e que o congelamento de preços, o ajuste fiscal e o caráter recessivo do plano foram questionados. Aqui, mostramos que essas afirmações são equivocadas. Analisando artigos, colunas e entrevistas publicadas à época, tentamos demonstrar que o plano econômico teve, durante suas primeiras semanas de vigência, amplo apoio de empresários, políticos, economistas e até mesmo da população do país.
Does wage reflect labor productivity? A comparison between Brazil and the United States
Authors: MAIA ALEXANDRE GORI , SAKAMOTO ARTHUR
Published: November 2018

ABSTRACT The study compares the relationship between wages and labor productivity for different categories of workers in Brazil and in the U.S. Analyses highlight to what extent the equilibrium between wages and productivity is related to the degree of economic development. Wages in the U.S. has shown to be more attached to labor productivity, while Brazil has experienced several economic cycles were average earnings grew initially much faster than labor productivity, suddenly falling down in the subsequent years. Analyses also stress how wage differentials, in fact, match productivity differentials for certain occupational groups, while for others they do not.
Education and development projects in Brazil, 1932-2004: a critique
Authors: KANG THOMAS H.
Published: November 2018

ABSTRACT The Second National Education Regulatory Framework (2nd LDB), enacted in 1971, changed the grade configuration of schooling levels in Brazil. This change made it challenging to construct a valid and reliable education spending data profile for 20th century Brazil. Previous work on the economic history of education in Brazil used the data provided according to the thesis of Maduro (2007). Wjuniski (2013) used that database and ran structural break tests and concluded that the Brazilian government underinvested in the expansion of secondary education. However, Wjuniski did not consider problems concerning: (i) data reliability and (ii) the effects of the 2nd LDB on education expenditure data. This paper shows that data on education spending in Brazil does not allow us to assert that there was an underinvestment in secondary education from 1971 onwards.

Abstract Breast cancer is the most common cancer affecting women in the world and provides functional changes in the human body. Evaluate women submitted to unilateral mastectomy, through electromyographic activity (mandibular rest, right and left laterality, protrusion, maximum voluntary contraction with and without Parafilm, habitual and non-habitual mastication) and thickness (rest and maximum voluntary contraction) of the right temporal muscle (RT), left temporal (LT), right masseter (RM) and left masseter (LM), also the molar bite force (right and left) and compare the data with healthy women. Material and Methods: 32 women were divided into two groups: unilateral mastectomy group (MG), average ± standard deviation 56.50±14.50 years (n=16) and without the disease group (CG), average ± standard deviation 56.56±14.15 years (n=16). The normalized electromyographic data, muscle thickness and maximal molar bite force were tabulated and submitted to statistical analysis (SPSS 21.0; student t test, p≤0.05). Significant statistical differences between MG and CG were found in right laterality, for RM (p=0.02); left laterality, for LT (p=0.01); chewing with peanuts, for RM (p=0.04); chewing with raisins, for LM (p=0.04) and right molar bite force (p=0.03). There was no statistically significant difference between MG and CG for muscle thickness. The results of this study suggest that women undergoing unilateral mastectomy may present functional changes, with emphasis on muscular hyperactivity, lower masticatory efficiency and lower maxillary bite force.

Abstract A caries-epidemiological study using the ICDASepi-merged system was conducted in Colombian young children. This study aimed at associating the time needed for the clinical examination of caries and caries risk in 1 to 5-year-old children according to age and caries risk, and to assess behavior and child pain self-perception during examination according to age. After IRB approval and given parents/caregivers’ informed consent, seven trained examiners assessed 1 to 5-year olds in kindergartens under local field conditions. ICDASepi-merged caries experience (depiMEmf) was assessed as follows: Initial-depi (ICDAS 1/2 without air-drying); Moderate-dM (ICDAS 3,4); Extensive-dE (ICDAS 5,6) lesions; due-to-caries fillings-f and missing-m surfaces/teeth. Caries risk was assessed with Cariogram®. Child’s behavior (Frankl-Behavior-Rating-Scale) and self-perceived pain (Visual-Analogue-Scale-of-Faces) during examination were evaluated. Clinical examination time was recorded with a stopwatch. A total of 592 children participated (1-yr.: n=31; 2-yrs.: n=96; 3-yrs.: n=155; 4-yrs.: n=209, 5-yrs.: n=101). The depiMEmfs prevalence was of 79.9% and the mean 8.4±10.4. Most were high-caries-risk children (68.9%). The majority (58.9%) showed ≥ positive-behavior and ≤ light-pain self-perception (88.4%). Mean clinical examination time was around 3.5 minutes (216.9±133.9 seconds). For 5-yr. olds it corresponded to 4 minutes (240.4±145.0 seconds) vs. 2 minutes (122.8±80.1 seconds) for 1-yr. olds (Kruskal-Wallis; p=0.00). For high- and low-caries risk children it was around 4.3 minutes (255.7±118.5 seconds) and 3.3 minutes (201.3±129.4 seconds), respectively (ANOVA; p=0.01). This study demonstrates using the ICDAS system in young children is feasible, taking less than 4 minutes for the clinical examination without children behavior/pain self-perception issues.

Abstract Religiosity has been associated with a better dental condition and positive self-perception of health, but there are no studies on the relationship between religious practice and oral health-related quality of life (OHRQoL), especially among schoolchildren. Thus, the aim of this study was to evaluate the association between family religiosity and OHRQoL in 12-year-old schoolchildren. We conducted a cross-sectional study in a representative sample of 12-year-old schoolchildren from Santa Maria, a city in southern Brazil. A total of 1,134 schoolchildren were assessed in a randomly selected in 20 public schools in the city. Participants were examined by 4 calibrated dentists (minimum Kappa-value for intra and inter-examiner agreement were 0.79 and 0.77, respectively) according to dental caries (Decayed, Missed, Filled Teeth Index), and gingival bleeding (Community Periodontal Index criteria). OHRQoL was assessed by the Brazilian short version of Child Perceptions for Questionnaire (CPQ11-14). Parents or guardians answered a structured questionnaire regarding their socioeconomic status and religious practice. Data were analyzed using multilevel Poisson regression analysis to assess the association of religiosity and overall and domain-specific CPQ 11-14 scores. Religious practice less than once a week was associated with higher mean symptoms domain scores and higher mean CPQ 11-14 overall scores in schoolchildren. In conclusion, our findings demonstrate that family religiosity was positively associated with schoolchildren’s OHRQoL.

Abstract Several techniques have been proposed for vertical bone regeneration, and many of them use bone autogenous and allogeneic grafts. The purpose of this study was to compare demineralised freeze-dried bone allografts (DFDBA), fresh-frozen (FF) allografts, autogenous bone grafts to find differences between volumetric and histological quantity of bone formation and vertical bone growth dynamic. A vertical tissue regeneration bone model was performed in rabbit calvarias under general anaesthesia. Four hollow cylinders of pure titanium were screwed onto external cortical bone calvarias in eight rabbits. Each one of the cylinders was randomly filled with one intervention: DFDBA, FF, autogenous bone, or left to be filled with blood clot (BC) as control. Allogeneic grafts were obtained from a ninth animal following international standardised protocols for the harvesting, processing, and cryopreservation of allografts. Autogenous graft was obtained from the host femur scraping before adapting hollow cylinders. Animals were euthanized at 13 weeks. Vertical volume was calculated after probe device measurements of the new formed tissue inside the cylinders and after titanium cylinders were removed. Histomorphometry and fluorochrome staining were used to analyse quantity and dynamic of bone formation, respectively. Results showed that DFDBA and fresh-frozen bone improved the velocity and the quantity of bone deposition in distant portions of the basal plane of grafting. Remaining material in allograft groups was more intense than in autogenous group. Both allografts can be indicated as reliable alternatives for volume gain and vertical bone augmentation.

ABSTRACT: The aim of this research was to characterize an environmental structure in the setting of tree natural water springs in a Lower Highland Seasonal Forest, and to verify the relationship between community demography and soil variables as subsidies for species identification in riparian forest recovery programs in similar environments. The research was carried out in the National Forest of Chapecó, located in the west of the state of Santa Catarina in the southern region of Brazil. For this, three water springs were demarcated, where 26 plots of 200m² in each were allocated. All individuals with diameter at 1.30m of soil height ≥5.0cm were measured. Soil samples (0 to 20cm depth) were collected in the plots for chemical and physical analysis. To relate the abundance of the species to the edaphic variables, the Canonical Correspondence Analysis (CCA) was used. A total of 76 species belonging to 64 genera of 36 botanical families were reported in the study area. The families Fabaceae and Myrtaceae presented greater floristic richness. The edaphic variables that most influenced the distribution of the species were aluminum saturation and calcium, magnesium and potassium contents. Specific groups of indicator species were formed for each water spring. The species designated as generalists are the most recommended for the initial filling and recovery of degraded springs. Further rare species and with low density must be included after the initial recovery to increase diversity.

ABSTRACT: The aim of this study was to analyze the expression of putative reference genes in sugarcane under drought stress. The varieties RB72454 and RB72910 were cultivated and the treatments control and drought stress applied to 135-day-old plants grown under field conditions. The stress level of the plants was measured by rate of photosynthesis, transpiration, and stomatal conductance. For each biological replicate, expression analyses were conducted using quantitative polymerase chain reaction for the genes α-tubulin, β-tubulin, β-actin, cyclophilin, eukaryotic elongation factor 1, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), histone H3 and ubiquitin. Stability was evaluated using the geNorm, NormFinder, and BestKeeper software packages. Among the candidate genes, GAPDH was identified as the most stable in all software, indicating its suitability for gene expression studies in sugarcane undergoing drought stress; the gene β-actin was the second most stable. These findings suggest using GAPDH and β-actin for normalization in relative gene expression in sugarcane.

ABSTRACT: Mammary tumors are the most frequent tumors reported in female dogs and have great relevance in veterinary oncology; however, little is known about the molecular mechanisms involved in the development of metastasis. An increasing number of human studies have suggested that epigenetic alterations, such as DNA methylation, miRNA, and histone modifications, are the predominant events leading to the metastatic phenotype in tumor cells and participate in regulating oncogenic signals associated with tumor spread. Among these epigenetic alterations, miRNAs have stood out in recent years, presenting a fundamental role in tumorigenesis. There are still few studies evaluating the role of miRNAs in canine mammary tissues. Thus, this paper aims to review the role of miRNAs in cancer with a special focus on canine mammary tumors.

ABSTRACT: The aim of this research was to evaluate the enhanced single-cell oil production by cold shock in Aphanothece microscopica Nägeli using dairy processing wastewater as culture medium. The study focused on (i) temperature optimization for biomass production, (ii) cold shock application to induce lipids biosynthesis and (iii) determination of fatty acids profile under different conditions. Results indicated that temperature of 20°C was the best condition in terms of kinetics parameter, reaching biomass productivities of 160.25mg/L.h. Under these conditions, a lipid content of 12.65% was also observed, resulting in a lipid productivity of 20.27mg/L.h. Additionally, the 0°C cold shock was the most efficient in increasing intracellular lipid content, reaching 28.4% in dry weight. Cold shocks also showed influence on the saturation of fatty acid composition, where the saturated fatty acids decreased, and the monounsaturated and polyunsaturated fatty acids increased by increasing the cold application. Thus, the use of cold shocks indicates to be a key condition for improving the prospects of efficient single-cell oils production.
