El traductor en el laberinto jurídico: el caso Dreyfus
El affaire Dreyfus fue un acontecimiento que estremeció a la sociedad francesa a finales del siglo XIX y, por ello, se convirtió en un fenómeno social que tuvo grandes repercusiones en Francia tanto a nivel político como social gracias a la información que facilitó la prensa y los medios de comunicación de la época. El llamado caso Dreyfus llegó a convertirse en la causa común de numerosos intelectuales (como Émile Zola, con su famoso artículo J’accuse) y sindicatos. Nuestro objetivo será, por tanto, el de analizar el laberinto lingüístico y terminológico al que se enfrenta el traductor de textos jurídicos, y para ello hemos elegido las sentencias del tres de junio de 1899 y del doce de julio de 1906 que fueron emitidas por la Cour de cassation francesa sobre este caso. Palabras clave: affaire Dreyfus; traducción judicial; terminología jurídica, arrêt; Cour de cassation.The so-called affaire Dreyfus was an historical event that made French society shudder at the end of 19th century and, consequently, it was an event that had widespread social and political repercussions in France owing to the fact that the press and contemporary mass media covered detailed information about such an affair. Actually, the mentioned Dreyfus affaire became a shared topic discussed by trade unions as well as by a number of intelectuals -such as Èmile Zola, for instance, with his well known press article J’accuse). Our aim in this paper is to discuss the linguistic and terminological maze faced by legal text translators, and with that aim in mind we have chosen the 3rd June 1899 and 12th July 1906 sentences which were delivered by the French la Cour de cassation about this affair. Key words: Dreyfus case; the legal text translation; legal terminology; arrêt; Cour de cassation
PTHrP treatment of colon cancer cells promotes tumor associated-angiogenesis by the effect of VEGF
We showed that Parathyroid Hormone-related Peptide (PTHrP) induces proliferation, migration, survival and chemoresistance via MAPKs and PI3K/AKT pathways in colorectal cancer (CRC) cells. The objective of this study was to investigate if PTHrP is also involved in tumor angiogenesis. PTHrP increased VEGF expression and the number of structures with characteristics of neoformed vessels in xenografts tumor. Also, PTHrP increased mRNA levels of VEGF, HIF-1α and MMP-9 via ERK1/2 and PI3K/Akt pathways in Caco-2 and HCT116 cells. Tumor conditioned media (TCMs) from both cell lines treated with PTHrP increases the number of cells, the migration and the tube formation in the endothelial HMEC-1 cells, whereas the neutralizing antibody against VEGF diminished this response. In contrast, PTHrP by direct treatment only increased ERK1/2 phosphorylation and the HMEC-1 cells number. These results provide the first evidence related to the mode of action of PTHrP that leads to its proangiogenic effects in the CRC.Fil: Calvo, Natalia Graciela.

Psychopathological verbal expression of self-perceived stress in three groups of psychotic patients
Producción CientíficaSelf-perceived stress in 293 psychotic patients (schizophrenic, toxic and brief reactive
psychoses) and a control group of 40 sane individuáis was evaluated by means of the
Frankfurt Complaint Questionnaire. For this purpose, scores obtained in 6 'complementary
Ítems' of the third versión of this questionnaire were studied, both in global and in
detailed form. These Ítems reflect coping mechanisms exerted towards situations
perceived as stressful which can produce clinical manifestations similar to the wellknown
'negative symptoms' of schizophrenia. Results show that self-perceived stress in
all groups of patients is significantly higher than in the control group. In contrast, no significant
differences among the three groups of patients are obtained. In conclusión, we
point out the relevance of studying the psychotic patient's self-perceived stress in order
to detect and minimize or even avoid the patient's risk situations, independen! of his/her
diagnosis. This will be especially useful to obtain optimal conditions for rehabilitatio

Enhancing ASD detection accuracy: a combined approach of machine learning and deep learning models with natural language processing
[EN] Purpose The main aim of our study was to explore the utility of artificial intelligence (AI) in diagnosing autism spectrum disorder (ASD). The study primarily focused on using machine learning (ML) and deep learning (DL) models to detect ASD potential cases by analyzing text inputs, especially from social media platforms like Twitter. This is to overcome the ongoing challenges in ASD diagnosis, such as the requirement for specialized professionals and extensive resources. Timely identification, particularly in children, is essential to provide immediate intervention and support, thereby improving the quality of life for affected individuals. Methods We employed natural language processing (NLP) techniques along with ML models like decision trees, extreme gradient boosting (XGB), k-nearest neighbors algorithm (KNN), and DL models such as recurrent neural networks (RNN), long short-term memory (LSTM), bidirectional long short-term memory (Bi-LSTM), bidirectional encoder representations from transformers (BERT and BERTweet). We extracted a dataset of 404,627 tweets from Twitter users using the platform’s API and classified them based on whether they were written by individuals claiming to have ASD (ASD users) or by those without ASD (non-ASD users). From this dataset, we used a subset of 90,000 tweets (45,000 from each classification group) for the training and testing of these models. Results The application of our AI models yielded promising results, with the predictive model reaching an accuracy of almost 88% when classifying texts that potentially originated from individuals with ASD. Conclusion Our research demonstrated the potential of using AI, particularly DL models, in enhancing the accuracy of ASD detection and diagnosis. This innovative approach signifies the critical role AI can play in advancing early diagnostic techniques, enabling better patient outcomes and underlining the importance of early identification of ASD, especially in children.SIUniversidad de Leó
Involvement of parathyroid hormone-related peptide in the aggressive phenotype of colorectal cancer cells
Colorectal cancer (CRC) remains one of the leading causes of mortality from malignant diseases worldwide. In general terms, CRC presents high heterogeneity due to the influence of different genetic and environmental factors; also, the neoplastic cells are strongly influenced by the extracellular matrix and several surrounding cells, known together as the tumor microenvironment (TME). Bidirectional communication takes place between the tumor and the TME through the release of autocrine and paracrine factors. Parathyroid hormone-related peptide (PTHrP) is a cytokine secreted by a wide variety of tissues and is able to regulate several cellular functions both in physiological as well as in pathological processes. It exerts its effects as a paracrine/autocrine factor, although its mode of action is mainly paracrine. It has been shown that this peptide is expressed by several tumors and that the tumor secretion of PTHrP is responsible for the malignant humoral hypercalcemia. Eight years ago, when our research group started studying PTHrP effects in the experimental models derived from intestinal tumors, the literature available at the time addressing the effects of PTHrP on colorectal tumors was limited, and no articles had been published regarding to the paracrine action of PTHrP in CRC cells. Based on this and on our previous findings regarding the role of PTH in CRC cells, our purpose in recent years has been to explore the role of PTHrP in CRC. We analyzed the behavior of CRC cells treated with exogenous PTHrP, focalizing in the study of the following events: Survival, cell cycle progression and proliferation, migration, chemoresistance, tumor-associated angiogenesis, epithelial to mesenchymal transition program and other events also associated with invasion, such us the induction of cancer stem cells features. This work summarizes the major findings obtained by our investigation group using in vitro and in vivo CRC models that evidence the parti cipation of PTHrP in the acquisition of an aggressive phenotype of CRC cells and the molecular mechanisms involved in these processes. Recently, we found that this cytokine induces this malignant behavior not only by its direct action on these intestinal cells but also through its influence on cells derived from TME, promoting a communication between CRC cells and surrounding cells that contributes to the molecular and morphological changes observed in CRC cells. These investigations establish the basis for our next studies in order to address the clinical applicability of our findings. Recognizing the factors and mechanisms that promote invasion in CRC cells, evasion to the cytotoxic effects of current CRC therapies and thus metastasis is decisive for the identification of new markers with the potential to improve early diagnosis and/or to predict prognosis, to predetermine drug resistance and to provide treatment guidelines that include targeted therapies for this disease.Fil: Novoa Díaz, María Belén.

Evaluation of the anaesthetic properties and tolerance of 1:100,000 articaine versus 1:100,000 lidocaine. : a comparative study in surgery of the lower third molar
Objectives: To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. Study Design: A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,000. The variables analysed were latency period, duration of anaesthetic effect, tolerance and adverse reactions. Results: Both the latency period and the duration of anaesthetic effect were greater for articaine, although the differences were not statistically significant. Latency: mean difference of 2.70 ± 2.12 minutes (95%CI of -1.51 minutes - 6.92 minutes). Duration: mean difference of -33 minutes 5 seconds ± 31 minutes (95% CI -1 hour 35 minutes - 29 minutes). There were 4 adverse events that did not require the patients to be withdrawn from the study. Conclusions: The anaesthetics in this study have very similar properties for use in surgery and have demonstrated a good safety and tolerability profile. © Medicina Oral
The Efficacy and Effectiveness of Education for Preventing and Treating Non-Specific Low Back Pain in the Hispanic Cultural Setting: A Systematic Review
[EN] A systematic review was conducted to assess the efficacy and effectiveness of education programs to prevent and treat low back pain (LBP) in the Hispanic cultural setting. Electronic and manual searches identified 1148 unique references. Nine randomized clinical trials (RCTs) were included in this review. Methodological quality assessment and data extraction followed the recommendations from the Cochrane Back Pain Review Group. Education programs which were assessed focused on active management (3 studies), postural hygiene (7), exercise (4) and pain neurophysiology (1). Comparators were no intervention, usual care, exercise, other types of education, and different combinations of these procedures. Five RCTs had a low risk of bias. Results show that: (a) education programs in the school setting can transmit potentially useful knowledge for LBP prevention and (b) education programs for patients with LBP improve the outcomes of usual care, especially in terms of disability. Education on pain neurophysiology improves the results of education on exercise, and education on active management is more effective than “sham” education and education on postural hygiene. Future studies should assess the comparative or summatory effects of education on exercise, education on pain neurophysiology and education on active management, as well as explore their efficiency.S

La alteración de sistemas natriuréticos renales se asocia con el desarrollo de hipertensión arterial y precede en el tiempo a la aparición de daño renal en un modelo de síndrome metabólico
Objetivos: El objetivo del trabajo consistió en determinar la existencia de alteraciones en los sistemas natriuréticos del péptido natriurético atrial y dopamina renal en un modelo de síndrome metabólico por sobrecarga de fructosa y asociarlas con cambios en la presión arterial sistólica, función renal, estado de la Na+, K+-ATPasa y microalbuminuria. Material y Métodos: Ratas macho Sprague-Dawley fueron divididas en grupos control (C) y fructosa (F) con agua o solución de F (10%P/V) para beber durante 4, 8 y 12 semanas. En orina, se midió L-dopa y dopamina, sodio, creatinina y albúmina; y en plasma péptido natriurético atrial, insulina, sodio y creatinina. La presión arterial sistólica fue medida por método indirecto. Se midió la actividad y expresión de la Na+, K+-ATPasa así como la expresión del receptor de péptidos natriuréticos A y C renales. Resultados: La sobrecarga de fructosa se asoció con el aumento de la insulinemia y la presión arterial sistólica, y con la disminución en la excreción urinaria de sodio desde la semana 4. La excreción urinaria de L-dopa se incrementó y la de dopamina disminuyó (cociente L-dopa/dopamina incrementado) por sobrecarga de fructosa desde la semana 4 y el péptido natriurético atrial plasmático se redujo en las semanas 8 y 12. Estos cambios fueron acompañados por un incremento de la actividad y expresión de la Na+, K+- ATPasa, disminución del receptor de péptidos natriuréticos A y aumento del C. La microalbuminuria se observó en la semana 12 de sobrecarga de fructosa.Background: The aim of this study was to determine the presence of alterations in the natriuretic systems of atrial natriuretic peptide and renal dopamine in a model of metabolic syndrome induced by fructose overload and to associate them with changes in systolic blood pressure, renal function, Na+/K+-ATPase status and microalbuminuria. Methods: Male Sprague-Dawley rats were divided into control (C) and fructose (F) groups receiving drinking water or a fructose solution (10% W/V), respectively, for 4, 8 and 12 weeks. L-dopa and dopamine, sodium, creatinine and albumin were measured in urine and ANP, insulin, sodium and creatinine in plasma. Systolic blood pressure was measured by indirect method and the renal activity and expression of Na+/K+-ATPase as well as the renal expression of A- and C-type natriuretic peptide receptors were assessed. Results: Fructose overload was associated with a significant increase in insulinemia and systolic blood pressure levels and a decrease in urinary sodium excretion since week 4. A significant increase in L-dopa excretion and a decrease in dopamine excretion (increased urinary L-dopa/dopamine ratio) due to fructose overload were observed since week 4 with a decrease in plasma atrial natriuretic peptide at weeks 8 and 12. These changes were accompanied by increased activity and expression of Na+/ K+-ATPase, decreased A-type natriuretic peptide receptor and increased C-type natriuretic peptide receptor expression. Microalbuminuria was observed at week 12 of fructose overload. Conclusions: Altered atrial natriuretic peptide and renal dopamine were associated with the development of hypertension and preceded in time the presence of microalbuminuria, thus establishing a temporal association between the alteration of both systems and the development of renal damage.Fil: Rukavina Mikusic, Natalia Lucía.
