Authors: Satrio Satrio , Prasetio Rasi , Hadian Muhamad Sapari Dwi , Syafri Ildrem
Published: February 2017

DOI: 10.17014/ijog.4.1.1-10A groundwater study has been conducted in the Semarang City in August 2014, aiming to determine the source of shallow groundwater salinization using stable isotopes (18O, 2H) and water chemistry approach, and supported by local hydrogeological data. A number of shallow groundwater samples were taken at several locations with a depth of 0 - 35 m. Based on geological data, shallow groundwater of Semarang alluvium is dominated by insertion of sand-gravel and sandy-clay with average porosity of around 56.0 %. This layer is thinning towards the south and then increasingly thickening to the north and north-east of the studied area. The results of the analyses show that the characteristics of shallow groundwater, i.e. approximately 51% of groundwater, still have the original composition as meteoric water and the remaining approximately 49% obtained a shift in the isotopic composition as caused by interaction with seawater and the little influence of evaporation. The results of chemical analysis of water indicates that in dry seasons, shallow groundwater aquifers in the Semarang City is dominated by chloride (Cl-) with NaCl of water type. While the parameters of bicarbonate, chloride, and Na/Cl ratio, shallow groundwater can be classified into two groups, namely unintruded groundwater around 51% spread from the foot hills to the south towards the hills with elevations of 9 - 142 m above sea level and intruded groundwater around 49% spread from the coastline to the urban direction.

Published: February 2017

This paper explores the direct effects and spillovers of unconventional monetary and exchange rate policies. We find that official purchases of foreign assets have a large positive effect on a country&amp;amp;#x27;s current account that diminishes considerably as capital mobility rises. There is an important additional effect through the lagged stock of official assets. Official purchases of domestic assets, or quantitative easing (QE), appear to have no significant effect on a country&amp;amp;#x27;s current account when capital mobility is high, but there is a modest positive impact when capital mobility is low. The effects of purchases of foreign assets spill over to other countries in proportion to their degree of international financial integration. We also find that increases in US bond yields are associated with increases in foreign bond yields and in stock prices, as well as with depreciations of foreign currencies, but that all of these effects are smaller on days of US unconventional monetary policy announcements. We develop a theoretical model that is broadly consistent with our empirical results and that highlights the potential usefulness of domestic unconventional policies as responses to the effects of foreign policies of a similar type.

Introdução: Estudos apontam que os exercícios físicos de intensidade moderada, especialmente os de endurance, têm efeito preventivo nas doenças cardiovasculares. Em contraposição, outros estudos mostram que o exercício quando praticado em alta intensidade induz à ocorrência de danos genéticos, os quais, por sua vez, associam-se ao processo de transformação maligna. Objetivo: Testar a hipótese de que atletas de futebol apresentam ocorrência de danos cromossômicos com maior aparecimento de micronúcleos, comparados com indivíduos sedentários ou praticantes de exercício físico não profissional. Métodos: A amostra analisada incluiu exclusivamente indivíduos do sexo masculino, de 18 a 38 anos, não fumantes, distribuídos em três grupos: Grupo I, formado por atletas de futebol, integrantes de um mesmo clube, submetidos à prática intensa de exercícios físicos; Grupo II, constituído por alunos da Universidade Estadual de Feira de Santana, matriculados no Programa de Exercício Físico do Laboratório de Atividade Física; e Grupo III, formado por indivíduos de hábitos sedentários. Resultados: Um total de 52.000 células foram analisadas. A análise das diferenças entre as médias de micronúcleos calculadas, feita com o uso da análise de variância, com um critério de classificação, não revelou diferença significante entre os grupo estudados (F2,49=0,11; p=0,88). Conclusão: Em conclusão, nosso estudo mostrou que a prática do futebol por atletas profissionais de alta intensidade não acarreta em danos ao DNA.

Authors: Santos Lays Rodrigues , Casa Junior Adroaldo José , Gardenghi Giulliano
Published: February 2017

Introdução: A trombose venosa profunda (TVP) é caracterizada pela formação de trombos nas veias profundas. É a principal causa de embolia pulmonar (EP), sendo de extrema importância que se realize a profilaxia da TVP. Objetivos: Verificar se a profilaxia para TVP em pacientes com fraturas de membro inferior em um hospital público voltado para atendimento de urgências está sendo eficiente, identificar as categorias de risco para TVP de acordo com a Sociedade Brasileira de Angiologia e Cirurgia Vascular (SBACV) e verificar o número de atendimentos de fisioterapia realizados nessa população durante internação hospitalar.  Metodologia: Estudo transversal quantitativo e analítico de 79 pacientes internados com uma ou múltiplas fraturas em membro inferior, entre abril e junho de 2016. Os dados foram coletados nos prontuários, sendo aplicado o protocolo de estratificação de risco para TVP da SBACV.  Resultados: Homens corresponderam 75,9% da amostra. A idade foi de 38,6 ± 18,2 anos. 1,3 % da amostra foram estratificados em baixo risco, 74,7% em médio risco e 24,1% em alto risco para TVP. 3,8% da amostra não receberam profilaxia medicamentosa. Os incluídos no estudo receberam atendimento fisioterapêutico a cada 2,6 dias durante período de internação e 2,5% da amostra apresentaram complicações, sendo um óbito e uma TVP com evolução para TEP. Conclusões: A profilaxia medicamentosa para TVP associado às manobras fisioterapêuticas foram eficazes na maioria dos pacientes estudados. A maior parte dos pacientes foi classificada como em médio risco para desenvolvimento de TVP. O número de sessões de fisioterapia durante o período de internação prestado foi considerado baixo, pela falta de pessoal associada ao serviço público em questão.

The study of interhelical angles in the structural motifs formed by two helices
Authors: Тихонов Д.А. , Tikhonov D.A.
Published: February 2017

In this paper a statistical analysis of distributions of inter-helical angles in pairs of consecutive and connected α-helices in spatial structures of proteins is presented.
A number of rules for selection of the helical pairs from a set of protein structures obtained from the Protein Data Bank (PDB) were developed. The set of helical pairs has been analyzed
for the purpose of classification and finding out the features of protein structural organization. All pairs of connected helices were divided into three subsets according
to the criterion of crossing of projections of the helices on parallel planes, which pass through the axes of the helices. It is shown that the distribution of all types
of helical pairs, whose projections do not cross each others, covers almost the entire range of inter-helical angles. The distribution have a single maximum which is close
to right angle. Most pairs in this set constitute helical pairs consisting of α- and 310-helices, and most pairs with the crossing projections of helices are helical pairs
formed by two α-helices. It is also shown that a great amount of the pairs of connected α-helices has acute angle 20° ≤ φ ≤ 60° between the axes of the helices.
The distribution of all types of helical pairs depending on the length of the inter-helical connections was also analyzed. It is shown that the structures with short connections
occur most often in all the subsets.

Considerações Políticas sobre a Vedação Legal da Liberdade Provisória: Tensões e Consensos no Julgamento do Habeas Corpus 104.339 e o Contexto da Lei 12.403/2011 / Political Considerations on the Legal Prohibition of the Provisional Freedom Benefit: Tensions and Consensus in the Trial of Habeas Corpus 104.339 and the Context of the Law 12.403/2011
Authors: Ferreira Otávio Dias de Souza
Published: February 2017

Resumo: Entre 1990 e 2006, o Congresso Nacional aprovou cinco Leis Federais dispondo sobre a vedação da concessão do benefício de liberdade provisória para acusados pela prática de diversas modalidades de delitos. Desde o início da vigência, cada um desses dispositivos legais encontrou resistências no Judiciário. Em 2011, foi sancionada uma nova regulação para as medidas cautelares penais, trazendo inovações nessa temática. O objeto central desta pesquisa é o julgamento de 10.05.2012, no Plenário do Supremo Tribunal Federal, do habeas corpus n. 104.339, sobre a constitucionalidade de dispositivo sobre a liberdade provisória da nova "Lei de Drogas". Por se tratar da decisão paradigmática mais recente sobre tal celeuma, tendo ocorrido após a reforma processual da Lei 12.403/2011 e pela grande quantidade de pessoas privadas da liberdade acusadas por tais delitos, o estudo desse julgamento ganha relevância especial. Após a reconstituição histórica da celeuma e a consideração sobre os conteúdos jurídicos envolvidos, atenta-se sobretudo para a dimensão política da decisão da Corte, de modo a oferecer uma perspectiva institucional ampliada para a compreensão da temática. Abstract: Between 1990 and 2006, the Congress approved five Federal Laws providing for the prohibition of the granting of the provisional freedom benefit to people accused of committing several criminal offenses. Since the effective date, each of these legal provisions found resistance in the judiciary. In 2011, a new regulation for criminal precautionary measures was introduced, bringing innovations in this area. The central object of this research is the judgment that happened in May 10, 2012, in the Plenum of the Federal Supreme Court, of habeas corpus no. 104,339, on the constitutionality of a provision on the provisional freedom benefit of the new "Drug Law". Since this is the most recent paradigmatic decision on this issue, having occurred after the procedural reform in the Law 12.403/2011 and the large number of persons deprived of liberty accused of such crimes, the study of this judgment gains special relevance. After the historical reconstitution of the controversy and the consideration of the legal contents involved, it focuses on the political dimension of the Court's decision, in order to offer an expanded institutional perspective for understanding the issue.
A Revolução Haitiana e o Atlântico Negro: o Constitucionalismo em face do Lado Oculto da Modernidade / The Haitian Revolution and the Black Atlantic: Constitutionalism in face of the Dark Side of Modernity
Authors: Piza Duarte Evandro Charles , Lustosa Queiroz Marcos Vinícius
Published: February 2017

Resumo: O presente artigo pretende ser um duplo movimento de reflexão sobre as categorias utilizadas para tratar da história do constitucionalismo moderno. Primeiramente, apresentará a categoria de "Atlântico Negro" e suas respectivas contribuições para uma "reperiodização" da modernidade, especificamente quanto aos movimentos sociais de reivindicação de direitos. Em seguida toma um evento particular desse Atlântico Negro, a Revolução Haitiana, como prisma hermenêutico e metodológico para pensar as disputas constitucionais. Busca-se, desse modo, adotar o ponto de vista de uma filosofia da história que lide, de maneira integrada, com a modernidade e o colonialismo. Por fim, tecerá breves comentários sobre como esse duplo movimento poderá contribuir para a reflexão sobre o direito constitucional contemporâneo. Abstract: The present paper aims to be a double movement of reflection about the history of modern constitutionalism. Firstly, it introduces the "Black Atlantic" category and its respective contributions to perform a "re-periodization" of modernity, specifically in relation to social movements of human rights. Then, it takes one particular event of this Black Atlantic, the Haitian Revolution, to be a methodological and hermeneutical prism to think the constitutional struggles. Thereby, the paper intends to embrace a point of view of the philosophy of history that deals with modernity and colonialism in an integrated manner. Lastly, it shows how this double displacement can contribute to the contemporary constitutional thought.

AbstractThe behavior of occupants in buildings has an enormous impact on their energy consumption. Despite the efforts to improve the energy efficiency in buildings, there are still many barriers that need to be overcome. Behavior change measures -to improve the energy performance of buildings- are focused on both, the design and the use and operation of buildings. If we are really committed to achieving the sustainable development objective to improve our society's well-being, special attention should be put into energy use behavior as it has been proven to be an effective way for improvement. ResumoO comportamento dos ocupantes em edifícios tem um enorme impacto no seu consumo de energia. Apesar dos esforços para melhorar a eficiência energética nos edifícios, ainda há muitas barreiras que precisam ser superadas. Medidas de mudança de condutas - para melhorar o desempenho energético dos edifícios - são focadas tanto no design como na utilização e operação de edifícios. Se estamos realmente empenhados em alcançar o objetivo de desenvolvimento sustentável para melhorar o bem-estar da nossa sociedade, uma atenção particular deve ser proporcionada em relação as condutas que influem no uso cotidiano de energia, uma vez que se provou ser um meio eficaz de progresso.
Contrastes entre a crítica literária especializada e amadora: os booktubers e os discursos sobre o livro e a leitura / Contrasts between the specialized and unprofessional literature critics: the booktubers and the discourses about the book and the reading

Published: February 2017

RESUMO: Este trabalho tem por objetivo descrever, pautado na Análise do Discurso francesa e na História Cultural, as práticas discursivas da representação contemporânea do leitor por meio de algumas reflexões sobre a crítica especializada e a amadora. Utiliza-se como recorte do corpus uma notícia veiculada no portal de entretenimento do UOL, intitulada “Mercado literário: Os booktubers vão substituir os críticos especializados?”, assinada por Rodrigo Casarin. Procura-se elencar e compreender as formações discursivas sobre o leitor comum e o leitor profissional, este entendido como a crítica literária profissional que se serve de uma leitura institucionalizada. Questiona-se: por que a crítica literária formal se reveste de prestígio, mas quando se quer vender as obras e movimentar o mercado editorial é preciso, na atualidade, promover o comentário amador? Quais os limites entre o leitor comum e o crítico especializado? Por que postar um vídeo na internet gera capital social para aquele que se denomina leitor voraz e aproxima leitores e escritores? Em termos de linguagem, o que se diz sobre a leitura na época da cibercultura? Para dar conta dessas indagações são utilizadas as reflexões teóricas encontradas nas obras de Orlandi (2012), Foucault (2010) e Chartier (1998, 2010).PALAVRAS-CHAVE: discurso; leitura; livros; crítica.  ABSTRACT: This paper aims at describing, based on the French Discourse Analysis and Cultural History, the discursive practices of contemporary representation of the reader through some reflections on the specialized and amateur critics. It is used as corpus cut one piece of news published on the entertainment portal UOL, under the title "Literary Market: will the booktubers replace the specialized critics?", signed by Rodrigo Casarin. It seeks to list and understand the discursive formations of the general reader and the professional player, this understood as the professional literary criticism that serves as an institutionalized reading. It wonders: why is the formal literary criticism of prestige, but when you want to sell the works and move the publishing market, it is necessary, at present, to promote the amateur comment? What are the limits between the general reader and the expert critical? Why does posting a video on the Internet give social capital to the one that is called a voracious reader and bring together readers and writers? In terms of language, what is said about reading at the time of cyberculture? To account for these reflections, theoretical reflections found in the works of Orlandi (2012), Foucault (2010) and Chartier (1998, 2010) are used.KEYWORDS: discourse; reading; books; critics.

Authors: Singh Ranvijay , Kashyap Rajesh , Bhardwaj Rajeev , Marwaha Rajeev , Thakur Manish , Singh Thakur Prashant , Kalawar Ritesh , Kumar Soni
Published: February 2017

Background: Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. In western countries, rheumatic heart disease (RHD) is a rare cause of atrial fibrillation but in developing countries like India it is one of the commonest cause of atrial fibrillation. We studied etiology, left atrial size and the incidence of left atrial appendage clot in patients with atrial fibrillation at our institution so that guidelines could be formulated to manage the patients of AF in the hours of emergency.Methods: 110 consecutive patients of atrial fibrillation coming to emergency, cardiology and medicine outpatient department over a period of one year were enrolled for the study. Ethical committee clearance was taken. Detailed history were taken, clinical presentation reviewed  and examination were carried out. All patients were subjected to transthoracic echocardiography and for transesophageal echocardiography if required.Results: The mean age of patients in the study was 58.42±14.27 years (range 22-90 years). Maximum numbers of patients were in the age group of 61-70 years (26.37%). Out of 110 patients with atrial fibrillation, 72 patients (65.46%) were females and 38 patients (34.54%) were males. Majority of patients presented with more than one symptom. Out of 110, 66 patients (60%) had RHD. Among RHD patients, 50 patients (45.55%) were females and 16 patients (14.55%) were males. Next common causes were hypertensive heart disease and degenerative valvular heart disease.Conclusions: In our study RHD was the most common cause of atrial fibrillation, followed by hypertensive heart disease and degenerative valvular heart disease. Mitral valve involvement was seen in all patients of RHD. Left atrial enlargement was seen in majority of patients, so left atrial enlargement could be a predictor of atrial fibrillation. Patients of left atrial enlargement are more prone to develop left atrial appendage clot.

Published: February 2017

Background: Acute subdural hematoma is the most common type of traumatic intra cranial hematoma accounting for 24% cases of severe head injuries and caries highest mortality. The aim of this study is to analyse the clinical spectrum, and to evaluate the postoperative outcome.Methods: This is a prospective observational Study which included 150 patients  admitted  in King George hospital, Andhra Medical College, Visakhapatnam, India over the past two years (01st August 2013 to 30th August 2015) with head injury, diagnosed to have Traumatic subdural Hemorrhage. A detailed clinical history, physical examination, CT scan was performed in all patients. Patients who were subjected to surgery, post-operative out-come were compared.Results: The maximum patients suffering from SDH are in the age group of 20-40 years (63%) with male predominance (73%). The most common mode of injury is RTA (73.33%). 40% of cases presented to hospital with gcs <8. Pupillary reaction, hypotension, CT scan findings i.e. thickness of hematoma >10mm and midline shift of >5mm, Basal cisterns obliteration, post traumatic seizure and delay in interval between the surgery had greatly affected on outcome of patients. Out of 150 cases, surgical approach was considered in 120 patients while remaining 30 patients were managed conservatively.Conclusions: Interval between injury to surgery with interval <4 hours having favourable outcome. Basal cistern obliteration, which is an indicator of increased intra cranial pressure is the single most important factor for unfavourable outcome. Hypotension and post traumatic seizures influence high mortality.
A comparative study of 4-hour versus 2-hour action line on who modified partograph
Authors: Sinha Divya , Shrivastava Sourabh , Shrivastava Swati
Published: February 2017

Background: World health organization has promoted modified partograph with action line, 4 hour to left of alert line. While others have used various action line 2, 3, or 4 hours to initiate and guide ‘‘active management’’ decisions. Objectives of the study were to evaluate outcome of labour in terms of caesarean section rate, augmentation of labour and fetal outcome in whom labour has been managed with 4-hour vs 2-hour action line on WHO modified partograph.Methods: This was a randomized, prospective, comparative study. Primigravida, 19-28 years, with single live foetus in vertex presentation without any medical and obstetrical complications, at term pregnancy have been included in the study. Results were compared between Group A, with 100 cases, in whom labour has been managed with WHO modified Partograph with 4-hour action line and Group B, with 100 cases, in whom labour has been managed with that of 2-hour action line.Results: The present study shows that more women in 2-hour arm crossed the action line, compared with the 4-hour arm, and therefore received more interventions to augment labour.  Rate of caesarean section is more in group B (11%) than in group A (9%) which is statistically nonsignificant.Conclusions: Neonatal outcome measured with APGAR score at 5 minute, has shown no significant difference in both groups. Therefore, partograph with 2-hour action line doesn’t show any superiority over that of 4-hour action line but to be associated with higher incidence of intervention. Further research is required in this field of active management.

Authors: Beheiry Hind Mamoun , Ali Ibrahim Abdelrhim , Rayis Duria A. M. , Saeed Amal M
Published: February 2017

Background: Creatinine clearance is safest method to measure glomerular filtration rate (GFR) in pregnancy. The objectives was to study a case-control study conducted in Omdurman Maternity Hospital aimed to assess GFR, using creatinine clearance and magnitude of changes of serum creatinine in pre-eclampsia.Methods: Pre-eclamptic were 70, normal pregnant 96 and non-pregnant 63. Investigations were done at St Hellier's hospital London. Serum and urine creatinine were measured using Jaffé reaction and spectrophotometer. 24-hour urine output was measured and creatinine clearance calculated to find GFR. GFR was calculated in ml/min/mm2 using John Hopkins’ method.Results: The mean serum creatinine in pre-eclamptic (68.6µmol/L) was less than non-pregnant (75.5µmol/L) (P=0.001) but was higher than normal pregnant (62.4µmol/L) (P=0.003). Mean GFR pre-eclamptic (68.6ml/min.1.73m2) was less than non-pregnant (87.0ml/min/1.73m2) (P=0.0001) and normal pregnant (89.0ml/min/1.73ml/min/1.73m2) (P =0.0001).Conclusions: GFR decreased at term in normal pregnancy and even more in pre-eclampsia. Serum creatinine levels increased and did not correlate with GFR changes in pre-eclampsia.

Background: Around 20% of patients with chronic hepatitis C infection (HCV) have persistently normal alanine aminotransferase (PNALT) levels. These patients are considered to have mild degree of histological hepatic damage. This study was conducted to compare the histological degree of necro-inflammation and stage of fibrosis among HCV patients with PNALT and patients with persistently or intermittently elevated serum ALT (PIEALT) levels..Methods: This study includes 154 untreated patients with serological and histological diagnosis of chronic HCV infection. A total of 70 patients with PNALT (group A) and 84 patients with PIEALT (group B) were identified and treated with 6 months interferon therapy. Histological grade of necro-inflammatory activity and the stage of fibrosis was evaluated by Ishak scoring system. HCV-RNA quantification was done by real-time polymerase chain reaction (PCR). Further univariate and multivariate analysis was done to evaluate correlation between patients characteristics and significant hepatic fibrosis..Results: Out of one hundred and fifty four patients, mean ALT was 30.59 ± 5.59 U/L in group A as compare to 68.65 ± 23.17 U/L in group B (p = 0.001). Patients with PNALT were younger (p = 0.005) with milder grade of necrosis (p = 0.037), lower serum HCV viral load (p = 0.044) and significant achievement of sustained virological response (p = 0.012) as compare to patients with abnormal ALT. Different variable were also analysed by univariate and mutivaraite analysis among patients with significant and insignificant fibrosis. High serum HCV-RNA level was found to be the independent variable predictive of advanced fibrosis among HCV infected patients (OR = 0.89; 95% CI = 1.65-1.94; p < 0.001) with r2 = 80%.Conclusions: Our study suggests that normal serum ALT does not mean healthy liver. So, histological evaluation is still an essential tool to assess liver damage precisely.

Background: Early detection of intracranial blood is essential for the rational use of anti hemostatic drugs in stroke patients. CT scan is quite expensive as well as it is not easily available especially in the rural areas. Clinical stroke scores were developed to overcome these limitations. Aim of present study is to identify the stroke subtype using Siriraj stroke scoring and thus asses its accuracy by comparing with CT scan reports.Methods: A cross sectional study was conducted in a tertiary centre that evaluated 464 patients admitted with a diagnosis of stroke. Siriraj Stroke score was calculated for each patient and a CT scan of brain was also taken. The results of diagnosis made by Siriraj stroke scoring were compiled and compared with the diagnosis obtained by CT Scan.Results: Of the total 464 patients, the incidence of hemorrhagic stroke was 27.8% and ischemic stroke was 72.2%, as per the CT scan reports, while the Siriraj stroke score diagnosed 16.8% patients to have hemorrhagic stroke and 74.6% to have ischemic stroke and no definite diagnosis was made in rest of the patients (8.6%). The sensitivity of the scoring was found to be 59.2% in diagnosing hemorrhagic stroke and 95.5% in ischemic stroke.Conclusions: Our study has shown that siriraj stroke scoring has a high degree of accuracy in detecting both types of strokes, with roughly 80% of both hemorrhagic and ischemic strokes being correctly identified. However there is a low sensitivity in diagnosing hemorrhagic strokes and higher sensitivity in diagnosing ischemic strokes.
Gamma glutamyl transferase as an atherogenic predictive marker in acute coronary syndrome
Authors: N. Sujesh Kumar , Krishnan Sajitha
Published: February 2017

Background: Acute coronary syndrome (ACS) remains a leading cause of mortality and morbidity world-wide. Atherosclerosis is the predominant cause of ACS and biomarkers that could detect vulnerable atherosclerotic plaque could potentially be of great value in identifying patients at risk of developing coronary events. The aim was to assess the role of gamma-glutamyl transferase (GGT) in atherosclerosis process. The objective was to compare serum levels of GGT in patients with ACS and control subjects, and also to find out the association between GGT and atherogenic risk factors such as diabetes mellitus, hypertension, dyslipidemia and smoking.Methods: The design was a prospective case control study where a total of 151 patients, 100 ACS patients and 51 control subjects with the age group of 30-80 years were enrolled for the study. GGT was estimated by kinetic colour test using Beckman Coulter AU2700 analyser.Results: The mean GGT levels of ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina (UA) subgroups were 93.86, 87.87 and 29.27 U/L respectively, which showed statistical significant difference (p<0.001) when compared with control subjects 21.99 U/L. The higher GGT levels in ACS patients also correlated with angiographic diagnosis of atherosclerosis. No significant difference was noted in GGT levels among ACS subgroups having risk factors and without having risk factors. Conclusions: Significantly higher GGT levels found in ACS patients reflects the burden of atherosclerotic changes and this association implies that GGT estimation can be used as an adjuvant biomarker that may help in identifying patients who are potentially at risk of coronary atherosclerosis.
Management of traumatised maxillary central incisor with immature open apex using mineral trioxide aggregate and tailor made gutta percha: a case report

Root development and apex closure after the eruption of teeth takes a minimum of 3-4 years. If trauma to the pulp occurs during this period, it becomes a challenge for the clinician to treat the pulpal injury. Apexification is the treatment of choice for necrotic teeth with immature apex. Apexification done with calcium hydroxide encounters certain difficulties like very long treatment time, possibility of tooth fracture and incomplete calcification of the bridge. Mineral trioxide aggregate (MTA) was introduced as an alternative material to traditional materials for the apexification of immature permanent teeth. This case report presents successful management of a case with open apex using MTA followed by Tailor made gutta-percha.

La tabula de los Ligures Baebiani: un testimonio epigráfico de la administración de Trajano
Authors: Blanch José María
Published: February 2017

El artículo trata sobre el programa de alimenta publica (fundaciones alimentarias) establecido por la Administración romana en tiempos del emperador Trajano (siglo ii d. C.) para proveer de un sustento básico a los niños de amplias regiones italianas. Para ello se sujetaban fincas rústicas a un gravamen para el pago de una renta alimenticia básica a niños de familias humildes. La tabula de los ligures baebiani es una fuente epigráfica que contiene la constitución de una fundación alimentaria de época de Trajano, en el sur de Italia, cerca de la actual Benevento, e información sobre los particulares que participaban en el programa y los caracteres de las fincas afectadas.
La Administración romana ante la gestión de residuos y tutela del hábitat
Authors: Zamora José Luis
Published: February 2017

Desde un punto de vista medioambiental, los problemas que normalmente se producen en las grandes ciudades están relacionados con los residuos, dada la concentración de viviendas y locales en un espacio reducido. Roma no supone una excepción, de ahí que haya existido una preocupación por la higiene y la gestión y evacuación de residuos urbanos, y que aún hoy en día siguen generando numerosos problemas. En el presente trabajo se hace una aproximación a algunas vicisitudes relacionadas con la gestión de residuos.
