Mudanças nos compostos bioativos e atividade antioxidante de pimentas da região amazônica.

A Embrapa Amazônia Oriental possui um Banco Ativo de Pimenteira com diferentes genótipos do gênero Capsicum, os quais ainda não foram analisados, quanto às suas características funcionais e capacidade antioxidante. Este estudo objetivou determinar os teores de ácido ascórbico, compostos fenólicos, carotenoides totais e a atividade antioxidante total, em frutos imaturos e maduros de genótipos de pimentas Capsicum spp. As concentrações de vitamina C (100,76-361,65 mg 100 g-1 nos frutos imaturos e 36,70-157,76 mg 100 g-1 nos maduros) decresceram com a maturação dos frutos. Carotenoides totais não foram detectados nos frutos imaturos, porém, nos frutos maduros, observaram-se valores de 73,80-1349,97 mg g-1, em função do genótipo. Os teores de compostos fenólicos aumentaram nos frutos maduros (147,40-718,64 mg GAE 100 g-1), para oito dos nove genótipos avaliados. Os frutos de pimenteira apresentaram significativa atividade antioxidante (55,02-92,03 mM trolox g-1 nos frutos imaturos e 39,60-113,08 mM trolox g- 1 nos maduros). Concluiu-se que o grau de maturação dos frutos influenciou nos teores de compostos bioativos dos genótipos estudados. Destacaram-se, como genótipos promissores com potencial para serem utilizados em programas de melhoramento genético, IAN-186301 e IAN-186324, pelos altos teores de carotenoides totais; IAN-186301, IAN-186311, IAN-186312 e IAN-186313, com relação às altas concentrações de ácido ascórbico; IAN-186304 e IAN-186311, pelos altos teores de compostos fenólicos; e IAN-186311, para atividade antioxidante

Stroke incidence and case fatality: a 9-year prospective population-based study in an elderly population of Bagheria, Italy

Background: The incidence of stroke in high-income countries has been on the decline; however, few epidemiological surveys have been conducted in recent years to specifically estimate the incidence along with outcome of stroke, in Italy. This study aimed to examine the incidence and case fatality rates of stroke in an elderly Italian population. Methods: A cohort of 2200 people > 65 years was randomly stratified from the total elderly population of Bagheria, Italy. A 9-year prospective population-based study was performed (19,800 person/years). Results: We identified 112 first-ever strokes, 53 females and 59 males: 82 (73.1%) ischemic, 13(11.6%) intracerebral haemorrhages, 6 (5.35%) subarachnoid haemorrhages, while 11(9.8%) were classified as undetermined strokes. The crude overall annual incidence was 5.65 per 1000 (95%CI: 4.61 to 6.70) for first-ever stroke. The overall crude incidence rates were 4.74 per 1000 (5.08 for males and 4.46 for females) for ischemic stroke, 0.65 (0.99 for males and 0.37 for females) for intracerebral haemorrhage, and 0.03 for subarachnoid haemorrhage. The incidence rate for first-ever stroke was 5.4 per 1000 (95% CI: 5.36 to 5.45) after adjustment for the 2015 World population and 5.56 (95% CI: 5.52 to 5.61), compared to the 2015 European population. Overall case fatality rates for first-ever stroke was 8.19% at 28 days and 24.1% at 1 year. Conclusion: Our study shows that in the elderly population investigated, stroke incidence and case fatality rates resulted being lower, compared to those from Italian and most European populations. Similar to previous studies, these rates increased linearly with age and were higher in males

Anti-Collapsin Response Mediator Protein 5(CV2/CRMP5) and Anti-Glutamic Acid Decarboxylase (GAD) Antibodies-Mediated Encephalopathy Mimicking Atypical Parkinsonism

Background: Paraneoplastic neurological syndromes (PNSs) are rare conditions characterized by immune-mediated pathogenesis, frequently associated with the presence of a neoplasm. Although a single antineuronal antibody mediates a specific syndrome, atypical manifestations mediated by the same antibody have been described. Methods: The aim of this study was to report on an atypical case of PNS with dual positivity for anti-GAD65 and anti-CRMP5/CV2 antibodies, simultaneously characterized by cognitive decline associated with progressive ataxia and parkinsonism. We also reviewed the current literature for published cases of PNSs with parkinsonism associated with anti-GAD65 and anti- CRMP5/CV2 antibodies. Results: A 68-year-old man with an insidious onset of bradykinesia, cognitive decline, and gait instability that began the year before our evaluation had been diagnosed with parkinsonian syndrome. Analysis of the cerebrospinal fluid showed lymphocytic pleocytosis, and a panel for PNS tested positive for anti-GAD65 and anti- CRMP5/CV2 antibodies. After investigation, a microcitoma was found in the lung. Conclusions: In light of our findings, we suggest considering PNS as an alternative diagnosis to parkinsonism-plus syndromes, in particular if bradykinetic syndrome is accompanied by other clinical manifestations including cognitive decline or ataxia in rapidly deteriorating patients. Earlier detection of PNS would lead to timelier identification of any occult tumors, therein promising improvement in the patient's prognosis

Impaired circadian heart rate variability in Parkinson's disease: A time-domain analysis in ambulatory setting

Background: Heart rate variability (HRV) decreases in Parkinson's disease (PD) and it can be considered a marker for cardiovascular dysautonomia. The purpose of this pilot study is to evaluate long-term time-domain analysis of HRV of PD patients and compare the results with those of matched healthy individuals. Methods: Idiopathic PD patients without comorbidity impairing HRV, and age-matched healthy individuals were recruited in a pilot study. A long-term time domain analysis of HRV using 24-h ambulatory ECG was performed. Results: Overall, 18 PD patients fulfilling inclusion criteria completed the evaluation (mean age was 55.6 ± 8.8, disease duration: 5.0 ± 4.7). Mean SCOPA-AUT score was 10.1 ± 7.3. Patients were on Hoehn & Yahr stage 1-2 and mean Levodopa Equivalent Dose (LED) was 311 ± 239.9. Mean of the 5-min standard deviation (SD) of R-R intervals distribution (SDNN) for all 5 min segments of the entire recording (ISDNN) was significantly lower in patients compared to controls. ISDNN was significantly different between Parkinson's disease patients and healthy controls. Conclusions: In our population characterized by mild to moderate disease severity, time-domain assessment of HRV seemed to be a potential tool to characterize cardiovascular dysautonomia. Decrease of ISDNN in PD may reflect an autonomic derangement extending all day and night long

Dismounting the classics. Didactic proposal based on a children and youth literature workshop for foreign language vocabulary teaching at the stage of primary education within the framework of Technique Feature Analysis

Uno de los principales objetivos de la Educación Primaria en España es el aprendizaje de una lengua extranjera. Las últimas leyes de educación, a pesar de sus diferencias, coinciden en la importancia de saber comunicarse en una lengua extranjera, tanto para fines sociales como profesionales. Así, presentan la adquisición de una segunda lengua como una prioridad dentro del sistema educativo español. El presente trabajo presenta una propuesta didáctica para trabajar el vocabulario en segunda lengua a través de la literatura infantil y juvenil. La propuesta está diseñada siguiendo el marco teórico “Technique Feature Analysis” (TFA), establecido por Nation y Webb para la adquisición de léxico en segunda lengua.One of the main aims within Primary Education in Spain is learning a foreign language. Despite the changes in the Spanish Education law along the last three decades, they all coincide in the importance of the ability to communicate in a foreign language in different types of situations. Thus, second language learning is given pride of place by the Spanish Educational system. The present work suggests a proposal to teach L2 vocabulary through popular children and youth literature. The proposal is designed within the theoretical framework of the Technique Feature Analysis (TFA), suggested by Nation and Webb to promote L2 vocabulary learning

The deconstruction of the folktale in Roald Dahl's Revolting Rhymes and the translation of its postmodern features into French and Spanish

Revolting Rhymes (1982) de Roald Dahl es una obra literaria infantil atípica en la que el autor galés actualiza y reescribe, tanto en forma como en contenido, seis cuentos populares. Este trabajo tiene dos objetivos: por un lado, evidenciar las características posmodernas de la obra y de qué manera estas contribuyen a lograr su propósito comunicativo; y, por el otro, analizar si dos de los elementos posmodernos más importantes del texto, la actualización de los aspectos culturales y la variedad de registros lingüísticos, están igualmente presentes en las versiones traducidas al francés y al castellano. Para ello, se han realizado dos estudios traductológicos contrastivos de tipo descriptivo con el fin de analizar la traducción de dichos elementos posmodernos en los textos meta en francés y castellano, aplicando la taxonomía de técnicas de traducción propuesta por Molina y Hurtado (2002).Revolting Rhymes (1982) by Roald Dahl is an atypical work of children’s literature in which the Welsh writer updated and rewrote six traditional folk tales in both form and content. This paper aims to evince the postmodern features of Revolting Ryhmes and the way in which they contribute to reach the communicative purpose of the literary work. The second objective of this work is to analyse if two of the most significant postmodern features (the cultural update and the variety of language registers) are also present in the Spanish and French translations. To do so, two descriptive and contrastive translation studies were carried out to analyse the translation of those features in the target texts in French and Spanish based on the proposal of translation techniques of Molina and Hurtado (2002)
