Nonsurgical endodontic retreatment of fused teeth with transposition: a case report
Cardoso, Miguel Agostinho Beco Pinto,Noites, Rita Brandao,Martins, Miguel Andre Duarte,Paulo, Manuel Pedro da Fonseca The Korean Academy of Conservative Dentistry 2016 Restorative Dentistry & Endodontics Vol.41 No.2
Tooth transposition is a disorder in which a permanent tooth develops and erupts in the normal position of another permanent tooth. Fusion and gemination are developmental disturbances presenting as the union of teeth. This article reports the nonsurgical retreatment of a very rare case of fused teeth with transposition. A patient was referred for endodontic treatment of her maxillary left first molar in the position of the first premolar, which was adjacent to it on the distobuccal side. Orthopantomography and periapical radiography showed two crowns sharing the same root, with a root canal treatment and an associated periapical lesion. Tooth fusion with transposition of a maxillary molar and a premolar was diagnosed. Nonsurgical endodontic retreatment was performed. At four yr follow-up, the tooth was asymptomatic and the radiolucency around the apical region had decreased, showing the success of our intervention. The diagnosis and treatment of fused teeth require special attention. The canal system should be carefully explored to obtain a full understanding of the anatomy, allowing it to be fully cleaned and obturated. Thermoplastic techniques were useful in obtaining hermetic obturation. A correct anatomical evaluation improves the set of treatment options under consideration, leading to a higher likelihood of esthetically and functionally successful treatment.

Images of a Continent : Questioning the Role of Pan-African Think-Tanks in the Reinvention of Africa
Cardoso, Carlos 한국외국어대학교 아프리카연구소 2013 Asian Journal of African Studies Vol.34 No.-
Taking stock from Ignacy Sachs book “La decouverte du Tiers monde”(1971), and inspired by Mudimbe’s seminal works The Invention of Africa(1988) and The Idea of Africa(1994), the paper discusses the images of Africa produced by Think Tanks. The author argues that while there is a plurality and diversity of worldviews, reflecting the ideologies and scientific disciplinary backgrounds that underpin them, in practice the challenges that confront us today on issues of alterity are not dissimilar to those that Sachs and others raised nearly half century age,. There is a need to question world views that establish hierarchies between the center, which is supposedly “civilized” and directs the world, and a periphery which is dominated and presumed “barbaric”. The author argues that the systematic study of the image of others, especially those produced by Think Tanks, cell for a critical engagement that would provide us with an opportunity for a multidisciplinary international collaboration in the field of social sciences research. There is still a long way to go in the field of knowledge production in order to address what the 2010 UNESCO’s World Report on Social Science called “Knowledge Divides” that relate to the imbalances that exist in terms of knowledge production in different parts of the world coupled with our persisting inability to address the current global social processes from a multidisciplinary point of view, free from preconceived ideas and bias of all kinds.

The aim of the present work is to evaluate the putative antidepressant-like effects of hydroethanolic and dichloromethanic extracts from the aerial parts of Sonchus oleraceus (Family Asteraceae) on the performance of male mice in the forced swimming test (FST) and tail suspension test (TST) models predictive of depression. The hydroethanolic and dichloromethanic extracts, both in doses of 30, 100, and 300mg/kg, were orally administered 1 hour before carrying out the FST or the TST. The immobility time in both the FST and the TST was significantly reduced by acute oral treatment with the extracts (dose range, 100–300mg/kg), without accompanying changes in ambulation, as assessed in an open-field test. This excluded the possibility that the effect of the extracts is due to an activation of locomotion. The efficacy of the extracts was found to be comparable to that of amitriptyline (10mg/kg, p.o.). The present study provides evidence for an antidepressant-like effect of the active principle(s) present in the extracts of S. oleraceus in mice. Therefore, a standardized S. oleraceus extract or its purified constituents could be of potential interest for the treatment of depressive disorders.
Epicardial Ablation of Ventricular Tachycardia: a Review
Rhanderson Cardoso,Arash Aryana,Sheldon M. Singh,Harikrishna Tandri,Andre d'Avila 대한심장학회 2018 Korean Circulation Journal Vol.48 No.9
For over 3 decades, it has been known that reentry circuits for ventricular tachycardia (VT) are not limited to the subendocardial myocardium. Rather, intramural or subepicardial substrates may also give rise to VT, particularly in those with non-ischemic cardiomyopathy. Percutaneous epicardial mapping and ablation has been successfully introduced for the treatment of such subepicardial VT. Herein, we review the indications for epicardial ablation and the identification of epicardial VT by electrocardiographic and imaging modalities. We also discuss the optimal technique for epicardial access and the implications of epicardial fat which has the potential to mimic scar, decreasing the specificity of electrogram morphology and impeding energy delivery to the tissue. Finally, we also report on possible complications of the procedure and strategies to mitigate adverse events.

Using sociolinguistic methodology for data collection and analysis, this study investigates the variable development of English word-final voiceless stops (codas) by Brazilian Portuguese (BP) speakers. In particular, based on phonetic evidence and along the lines of Goad (2002), the study provides evidence for an intermediate developmental stage in the acquisition of English codas by BP speakers, characterized by the phenomenon of Onset- Nucleus Sharing (ONS). Under this analysis to the syllabification of syllablefinal consonants, it is assumed that the potential coda (C) syllabifies as an onset (O) and, in order to be licensed, some of its features spread into the following empty nucleus (N) in order to optimize the syllable shape of the emerging grammar (i.e., to render a highly marked ONC syllable ? e.g., [Sp] ? into a relatively less marked ON.ON structure ? e.g., [S.ph]).

Objectives: The purpose of the present study was to evaluate the effect of calcium hydroxide with 2% chlorhexidine gel (HCX) or distilled water (HCA) compared to triple antibiotic paste (TAP) on push-out bond strength and the cement/dentin interface in canals sealed with White MTA Angelus (WMTA) or Biodentine (BD). Materials and Methods: A total of 70 extracted human lower premolars were endodontically prepared and randomly divided into 4 groups according to the intracanal medication, as follows: group 1, HCX; group 2, TAP; group 3, HCA; and group 4, control (without intracanal medication). After 7 days, the medications were removed and the cervical third of the specimens was sectioned into five 1-mm sections. The sections were then sealed with WMTA or BD as a reparative material. After 7 days in 100% humidity, a push-out bond strength test was performed. Elemental analysis was performed at the interface, using energy-dispersive spectroscopy. The data were statistically analyzed using analysis of variance and the Tukey test (p < 0.05). Results: BD presented a higher bond strength than WMTA (p < 0.05). BD or WMTA in canals treated with calcium hydroxide intracanal medications had the highest bond strength values, with a statistically significant difference compared to TAP in the WMTA group (p < 0.05). There were small amounts of phosphorus in samples exposed to triple antibiotic paste, regardless of the coronal sealing. Conclusions: The use of intracanal medications did not affect the bond strength of WMTA and BD, except when TAP was used with WMTA.

Resumo. Buscaremos reler o personagem emblemático Dom Quixote em sua preconizada insanidade ou idiotia, como possível analogia à passividade e subserviência do colonizado, a seu propalado silenciamento identificado ao temor ou à ignorância, ao seu idealismo avesso à praticidade do homem moderno, ao não exercício da consciência dos processos; e, em seu lugar, oferecer uma leitura pelo avesso que contemple a atitude como possibilidade de trânsito, modo de dizer, condição estratégica de andança, sobrevivência, errância. Europeu desalojado na própria Europa hispânica, personagem ibero-americano que continua se oferecendo a múltiplas leituras, transita nas fronteiras literárias e sociais; pretendemos ler a errância do cavaleiro como estratégia de sobrevivência. Analogamente, podemos expressar a condição paradoxal do discurso latinoamericano que inscreve em sua história tanto a dependência histórico-cultural pari passu à hegemonia da Europa Ocidental, quanto o modo de existência a que chamamos modernidade. A América Latina, ao mesmo tempo em que integra o projeto moderno, em grande parte fica alijada de seus frutos, integrando uma globalização com regiões pouco ou nada globalizadas. Traremos, numa visão interdisciplinar, a questão da tradição manchada da nossa literatura, e a saudável expansão dos gêneros impuros. Resumen. Buscaremos, releer el personaje emblemático Don Quijote en su reconocida locura o idiotez, como posible analogía a la pasividad y al servilismo del colonizado, a su propalado silenciamiento identificado al temor o a la ignorancia, a su idealismo contrario a la funcionalidad del hombre moderno, a escasez de ejercicio de la conciencia de los procedimientos; y, en su lugar, ofrecer una lectura al revés que contemple la actitud como posibilidad de tránsito, modo de decir, condición estratégica de caminante, superviviente, errante. Europeo desalojado en la propia Europa hispánica, personaje iberoamericano que continúa ofreciéndose a múltiples lecturas, transita en las fronteras literarias y sociales; pretendemos leer el caballero errante como estrategia de supervivencia. Análogamente, podemos expresar la condición paradójica del discurso latinoamericano que inscribe en su historia tanto la dependencia histórico cultural paralelamente a la hegemonía de la Europa Occidental, cuanto el modo de existencia que llamamos modernidad. La América Latina, al mismo tiempo en que integra el proyecto moderno, en su mayoría es excluida de los logros, integrando una globalización con regiones poco o nada globalizadas. Traeremos, en una visión interdisciplinaria, la tradición manchada de nuestra literatura y la saludable expansión de los géneros impuros.
