Ultrastructural and morphometric analysis on the ovary of Wistar rats after chronic ethanol ingestion

In the present study, seventy-two adult rats (Rattus norvegicus albinus) aged three months were used. The animals were divided into two groups (control and alcoholic). The control group received a solid diet (Purina rat chow) and tap water ad libitum. The alcoholic group received the same solid diet and sugar-cane liquid (trade 51, 41° Gay Lussac - GL) diluted 30° GL. At the end or 90, 180 and 270 days of treatment, ten rats of each group were anaesthetized with ethyl ether and sacrificed. The ovaries were collected, fixed, included and submitted to analysis by both light and electron microscopy. The alcoholic group showed increase in the number of corpora lutea at both 180 and 270 days of treatment, atresic follicles at 270 days of treatment, decreased diameter of corpora lutea at 180 and 270 days of treatment, the granulosa layer of the antral follicles at 180 days of treatment, and gradual regression of the theca antral follicles. Furthermore, an increase in diameter and posterior regression of the antral follicle were observed, as well as vacuolation, increased lipid droplets in the granulosa cell at 90 days and in the theca at 180 and 270 days of treatment and gradually in the interstitial cell. The rats showed ovarian alterations after ingestion of alcohol. There was a correlation between exposure time to the drug and the injury observed.

Apert syndrome: Analysis of associated brain malformations and conformational changes determined by surgical treatment

Apert Syndrome, also called acrocephalosyndactylia type 1, is characterized by craniostenosis with early fusion of sutures of the vault and/ or cranial base, associated to mid-face hypoplasia, symmetric syndactylia of the hands and feet and other systemic malformations. CNS malformations and intracranial hypertension are frequently observed in these patients. Early surgical treatment aims to minimize the deleterious effects of intracranial hypertension. Fronto-orbital advancement, the usual surgical technique, increases the intracranial volume and improves the disposition of encephalic structures previously deformed by a short skull. This study analyzes CNS alterations revealed by magnetic resonance in 18 patients presenting Apert Syndrome, and the conformational alterations in the encephalic structures after surgical treatment. The patients' age in February 2001 ranged from 14 to 322 months (m=107). Image study included brain magnetic resonance showing ventricular enlargement in five cases (27.8%), corpus callosum hypoplasia in five cases (27.8%), septum pellucidum hypoplasia in five cases (27.8%), cavum vergae in two cases (11.1%) and, arachnoid cyst in the posterior fossa in two cases (11.1%). Absence of CNS alterations was noted in 44.4% of cases. A corpus callosum morphologic index was established by dividing its height by its length, which revealed values that ranged from 0.4409 to 1.0237. The values of this index were correlated to the occurrence or absence of surgical treatment (p=0.012; t=2.83). Data analysis allowed the conclusion that the corpus callosum morphologic measure quantified the conformational alterations of the cerebral structures determined by the surgical treatment.

Theoretical Referents in Knowledge Organization: A Domain Analysis of the Knowledge Organization Journal

Aiming at contributing to the epistemological characterization of the area of knowledge organization, our goal is to analyze the KO journal, since its creation in 1993, as a knowledge domain, from a nuclear community of the most productive and greater impact authors, analyzing the dialogue among citing authors and cited ones, and also the co-citations established by the citing authors. We worked with a corpus of 310 articles published between 1993 and 2011 produced by a total of 360 authors. The relatively more productive authors, a group geographically concentrated in Europe (37%), North America (44%) and Asia (19%), is clearly explained by the historical European origin of the ISKO and by an increasing North American presence along the years. Of the 33 most cited authors, 22 were co-cited in at least 6 works, which suggests that they are the theoretical referential nucleus of the area, in the studied journal. Finally, we observe that the area reveals theme cohesion and coherence in its production, enabling us to clearly visualize its theoretical referential nucleus and to confirm the role performed by the KO magazine as a catalyzing agent of international theoretical construction in the area.

A explicitação como traço de um habitus tradutório para brasileirismos terminológicos em língua inglesa: um estudo baseado no corpus da obra O Povo Brasileiro, de Darcy Ribeiro

The main purpose of this article is to investigate the social and linguistic behaviors (the habitus) of a translator in face of cultural barriers in translation, analyzing the use of explicitation aspects in the translational process into English of the terminological Brazilianisms developed by Darcy Ribeiro. With this aim, we used a parallel corpus composed by the work O povo brasileiro (1995) and by its respective translation, performed by Rabassa. The methodology used is that of Corpus-Based Translation Studies (BAKER, 1993, 1995, 1996, 2000; CAMARGO, 2005, 2007), Corpus Linguistics (BERBER SARDINHA, 2004) and Terminology (BARROS, 2004). For data analysis, we adopted Sociology of Translation theories (SIMEONI, 1998, 2007; GOUANVIC, 1995, 1999), as well as the habitus conception, proposed by the sociologist Pierre Bourdieu (1980). We believe that, as pointed by Baker`s theories (1996), explicitation is a translator`s tendency or procedure, which explains, in the translated text, parts of the original text that have been left implicit by the author. Results show that this action may be found in Ribeiro’s translated texts, indicating the difficult of conceptualizing the Brazilian universe in English.

O fantástico traduzido: uma análise baseada em corpus paralelo e reflexões para uma pedagogia da tradução

This paper presents the analysis and the methodological procedures adopted in order to compile a parallel corpus comprised of two short stories by David Roas (2007; 2010), originally written in Spanish “Tránsito” and “Das Kapital”, and their translation into Portuguese carried out both by a native speaker of Spanish (fluent in Portuguese) and a native speaker of Portuguese (fluent in Spanish). We analyzed the texts translated by them, focusing on the most frequent vocabulary and its semantic implications on their respective contexts. The theoretical and methodological approach was based on corpus linguistics, corpus based translation studies (BAKER, 1996; HUNSTON, 2002; LAVIOSA, 2002; BERBER SARDINHA, 2004; MEYER, 2004; OLOHAN, 2004) and some concepts from Fantastic Literature (ROAS, 2001, 2011; TODOROV, 2003; ALAZRAKI, 2001). The data were extracted by using the WordSmith Tools Suite®. Results show that dialogue and focus on lexicon, making use of computer corpus, play an important role in understanding the translation process. It is also important to mention that while exploring translation possibilities presented by the two translators this approach unlocked a window to reflect on translation pedagogy based on corpus.

Time series analysis of jaw muscle contraction and tissue deformation during mastication in miniature pigs

Masticatory muscle contraction causes both jaw movement and tissue deformation during function. Natural chewing data from 25 adult miniature pigs were studied by means of time series analysis. The data set included simultaneous recordings of electromyography (EMG) from bilateral masseter (MA), zygomaticomandibularis (ZM) and lateral pterygoid muscles, bone surface strains from the left squamosal bone (SQ), condylar neck (CD) and mandibular corpus (MD), and linear deformation of the capsule of the jaw joint measured bilaterally using differential variable reluctance transducers. Pairwise comparisons were examined by calculating the cross-correlation functions. Jaw-adductor muscle activity of MA and ZM was found to be highly cross-correlated with CD and SQ strains and weakly with MD strain. No muscle’s activity was strongly linked to capsular deformation of the jaw joint, nor were bone strains and capsular deformation tightly linked. Homologous muscle pairs showed the greatest synchronization of signals, but the signals themselves were not significantly more correlated than those of non-homologous muscle pairs. These results suggested that bone strains and capsular deformation are driven by different mechanical regimes. Muscle contraction and ensuing reaction forces are probably responsible for bone strains, whereas capsular deformation is more likely a product of movement.

A contrastive analysis of epistemic modality in scientific English

[ES] This paper investigates the use of epistemic expressions in scientific English. The main aim of this research is to analyse if native speakers of English use epistemic modality in the same way than non-native speakers of English and to detect the most outstanding cognitive implications of this fact. The corpus used in this research contains 50 research papers written by native English speakers and 50 scientific papers written by Spanish researchers who use English to communicate internationally. As epistemic modals are used to indicate the possibility of some piece of knowledge, this paper focuses on epistemic modal verbs in order to detect if native speakers of English and non-native speakers of English communicate modality in the same way, or if there are differences in frequency and use. The results obtained in this analysis indicated that there are differences in the frequency of use of epistemic expressions, even if the intention of the writers is the same.

Corpora in the Social Sciences- How corpus-based appraches can support qualitative interview analyses

[EN]Qualitative and quantitative research approaches are often considered as incompatible, and when they are brought together in a study, the analyses often stay within the realm of the same research field. The study at hand aims at combining the two methods from the perspectives of different disciplines and tries to determine to which degree a corpus-based analysis might support the traditional content-focused approach to qualitative data and render additional results.

Author stance in doctoral dissertations of native and non-native speakers of English: a corpus-based study on epistemic adverbs

[EN]Our study concentrates on the epistemic adverbs used in conveying author stance in academic English. The Contrastive Interlanguage Analysis (Granger, 1996) was run to three sets of corpora comprising doctoral dissertations written by native and non-native academic authors of English. Epistemic adverbs occurring in the dissertations were identified through a computer programme and their frequencies were separately computed for each corpus. Lastly, a log-likelihood test was administered to see whether there is a statistically significant difference across the groups in concern concerning the use of these adverbs.
