Authors: Silva Leosmar Aparecido da 
Published: August 2017

<p>Este artigo tem o objetivo de analisar os usos do verbo pegar, especialmente em construções idiomáticas, em dados de língua falada. Metodologicamente, foram coletadas ocorrências do verbo pegar no corpus do Fala Goiana, gravado e transcrito pelo Grupo de Estudos Funcionalistas da UFG. Guiado pelas considerações teóricas da linguística cognitiva, o artigo analisa os usos de pegar em construções idiomáticas, considerando-se a frequência de uso, a mudança de sentido pelo uso, os graus de transparência e opacidade de algumas construções e a aplicação de esquemas imagéticos. Os resultados deste trabalho revelaram que o verbo pegar apresenta alta frequência de uso, o que contribuiu para que ele espraiasse seu estatuto semântico e suas funções lexicais e funcionais. O estudo revelou também que as construções idiomáticas apresentam grau de opacidade ora baixo ora alto. O estudo pode contribuir para a ampliação da gama de estudos sobre particularidades linguísticas de construções idiomáticas do português do Brasil.</p><p>Palavras-chave: Cognição. Construção.

La metáfora de la búsqueda: análisis de la metaforización kinésica en dos narraciones orales en gallego y portugués
Authors: Rivas Aitor 
Published: August 2017

<p>Muchos investigadores, partiendo de las ideas de Hall (1959, 1968), mantienen que el 60% de la comunicación personal es absolutamente no verbal, creyendo asimismo que es mucho más importante lo que transmitimos con nuestros gestos que lo que expresamos verbalmente. Mi corpus de estudio para este trabajo está conformado por la grabación de dos narraciones orales de hablantes nativas de gallego y portugués de Brasil. En este artículo pretendo analizar la intervención de la comunicación no verbal en los procedimientos de metaforización kinésica para transmitir y representar metáforas en esos relatos orales. La metodología de trabajo está basada en las propuestas de análisis de comunicación no verbal formuladas por Birdwhistell (1952, 1970), Poyatos (1994a, 1994b), Bouvet (2001) y Galhano Rodrigues (2007). Después del análisis se puede observar la alta capacidad metafórica de los procedimientos kinésicos.</p><p><br />Palabras-clave: Metaforización. Kinésica. No verbal. Oralidad. Búsqueda.</p>
Música, linguística e cognição

Published: August 2017

<p>As pesquisas sobre a psicologia cognitiva da música têm se focado prioritariamente na música tonal e a escola cognitivista da década de 1980 buscou formular uma teoria do comportamento humano em termos de sistemas de <em>competências </em>(musicais). Neste artigo faremos uma leitura do artigo “Music, linguistics, and cognition”, de Imberty (2011), no qual este autor analisa a obra de Lerdahl e Jackendoff mostrando as possibilidades e limitações de sua teoria, a GTTM (Teoria Gerativa da Música Tonal). Além disso, ele destaca os aspectos da obra de Jonh Sloboda, que também analisa a GTTM, e discute seus conceitos e implicações. Lerdahl e Jackendoff foram influenciados pela obra de Chomsky, que traz as concepções de inatismo, a assim propõem uma abordagem generativa para o estudo cognitivo da música. Imberty mostra os questionamentos de Sloboda a respeito da teoria de Lerdahl e Jackendoff e traz à tona as limitações da corrente destes autores. Para explicitar as características da GTTM e a fim de exemplificar esta teoria, faremos também uma análise da canção “Garota de Ipanema”, ícone da música brasileira, de acordo com as categorias propostas pelos autores. </p>

Para tanto, nos apoiamos nas abordagens ascendente, descendente e sociointeracionistas de leitura (CARREL et al., 1995; DURAN, 2009; FAIRCLOUGH, 1989; GOODMAN, 1976; HUDSON, 2007; LEFFA, 1999), no intuito de discutir as mudanças relacionadas aos fenômenos envolvidos no processo de compreensão leitora. Discutiremos, também, as características do hipertexto, bem como sua leitura a partir da abordagem ecológica da cognição (LÉVY, 2004), confrontando, também, as visões de autores como Snyder (1998) e Xavier (2002). Desse modo, procuramos abordar aspectos relacionados ao processo de leitura, em especial o de hipertextos, considerando os fatores incidentes tanto no sistema de percepção visual quanto no processamento cognitivo de informações relacionadas à linguagem verbal escrita. Por fim, consideramos que nenhuma leitura é linear, uma vez que a cognição humana funciona por meio de associações. Portanto, a leitura tanto de textos impressos quanto de textos virtuais pode ser considerada hipertextual.</p><p><strong> </strong></p>

Published: August 2017

Background: Men’s university ice hockey has received little scientific attention over the past 30 years, a time in which the traits of the players and the demands of the game have evolved. Objectives: This study compared the physiological characteristics of university ice hockey players and examined the frequency and duration of the different movement patterns and heart rate (HR) responses during competition. Methods: Twenty male ice hockey players from the same team ( age ± SD = 22±2 years) underwent a fitness evaluation and were filmed and HR monitored during regular season games. Results: Forwards and defense had similar fitness and only differed on % fatigue index and peak heart during on-ice sprinting (P<0.05). Defense stood, glided and skated backwards more than forwards and forwards skated at a moderate intensity and glided forward more than defense (P<0.05). All players spent the majority of game time gliding forward (60% of the time) followed by skating forward at a moderate intensity (17%) and standing with little movement (9%). Average HR during the game reached 96 and 92 % and peak HR was 100 and 96 % of maximum in forwards and defense, respectively. Conclusions: Male university hockey players present with a high level of physical fitness in a variety of categories with few differences between forwards and defense. Movement patterns during games suggest that players are performing low to moderate intensity on-ice activities the majority of the time. Paradoxically, HR continues to climb to near maximum during on ice shifts.
The key role of microtubules in hypoxia preconditioning-induced nuclear translocation of HIF-1α in rat cardiomyocytes

Published: August 2017

Background
Hypoxia-inducible factor (HIF)-1 is involved in the regulation of hypoxic preconditioning in cardiomyocytes. Under hypoxic conditions, HIF-1α accumulates and is translocated to the nucleus, where it forms an active complex with HIF-1β and activates transcription of approximately 60 kinds of hypoxia-adaptive genes. Microtubules are hollow tubular structures in the cell that maintain cellular morphology and that transport substances. This study attempted to clarify the role of microtubule structure in the endonuclear aggregation of HIF-1α following hypoxic preconditioning of cardiomyocytes.

Methods
Primary rat cardiomyocytes were isolated and cultured. The cardiomyocyte culture system was used to establish a hypoxia model and a hypoxic preconditioning model. Interventions were performed on primary cardiomyocytes using a microtubule-depolymerizing agent and different concentrations of a microtubule stabilizer. The microtubule structure and the degree of HIF-1α nuclear aggregation were observed by confocal laser scanning microscopy. The expression of HIF-1α in the cytoplasm and nucleus was detected using Western blotting. Cardiomyocyte energy content, reflected by adenosine triphosphate/adenosine diphosphate (ATP/ADP), and key glycolytic enzymes were monitored by colorimetry and high-performance liquid chromatography (HPLC). Reactive oxygen species (ROS) production was also used to comprehensively assess whether microtubule stabilization can enhance the myocardial protective effect of hypoxic preconditioning.

Results
During prolonged hypoxia, it was found that the destruction of the microtubule network structure of cardiomyocytes was gradually aggravated. After this preconditioning, an abundance of HIF-1α was clustered in the nucleus. When the microtubules were depolymerized and hypoxia pretreatment was performed, HIF-1α clustering occurred around the nucleus, and HIF-1α nuclear expression was low. The levels of key glycolytic enzymes were significantly higher in the microtubule stabilizer group than in the hypoxia group. Additionally, the levels of lactate dehydrogenase and ROS were significantly lower in the microtubule stabilizer group than in the hypoxia group.

Conclusion
The microtubules of cardiomyocytes may be involved in the process of HIF-1α endonuclear aggregation, helping to enhance the anti-hypoxic ability of cardiomyocytes.

ObjectiveCirculating endothelial progenitor cells (EPCs) correlate negatively with obesity. Previous studies have shown that exercise significantly restores circulating EPC levels in obese people; however, the underlying mechanisms have not been elucidated. Recently, irisin has been reported to have a critical role in the regulation of EPCs. This exercise-induced myokine has been demonstrated to play a therapeutic role in obesity. In this study, we hypothesized that the increase in circulating irisin may form a link with increasing EPC levels in obese people after exercise.MethodsSeventeen obese adults completed an 8-week program of combined exercise and dietary intervention. Clinical characteristics, blood biochemistry, and circulating irisin levels of subjects were measured before and after eight weeks of training. EPC levels were evaluated via flow cytometry, and EPC migratory and adhesive functions were also determined.ResultsCirculating irisin levels significantly increased following the 8-week training program (P < 0.05). We furthermore observed an improvement in EPC numbers (P < 0.05), and EPC migratory and adhesive functions (P < 0.001 andP < 0.05, respectively) after the intervention. Additionally, we detected a positive correlation between changes in irisin and changes in EPC number (r = 0.52,P < 0.05).DiscussionFor the first time, a positive correlation between increasing irisin levels and increasing EPC levels has been reported after an 8-week program, consisting of exercise and dietary intervention. This result suggests a novel effect of irisin on the regulation of EPC mobilization, which might contribute to improvement of endothelial function in obese people.

Published: August 2017

The effect of Santa Ana winds on bio-optical properties (absorption coefficients of particles, detritus and phytoplankton) off Baja California (Mexico) was evaluated using data obtained during four cruises in January, April, August and October 1999. Meteorological data from a station at Todos Santos Bay and satellite-derived wind data indicated three Santa Ana events during October 1999, with low relative humidity, high air temperature and persistent ENE winds. The absorption coefficient of detritus (adT) in surface samples was ten-fold higher in October because of the inorganic material wind-driven by the Santa Ana events that occurred from 9 to 11 and from 17 to 20 October, 1999. The absorption coefficients of particles (ap) and phytoplankton (aɸ) in the euphotic zone were higher in the April survey as a result of higher phytoplankton abundance. The ap, a and Kd values in the euphotic zone were fitted to chlorophyll using a power function, with an explained variance of 37%, 72% and 16%, respectively. On excluding the October adT surface values, chlorophyll explained 82% of the changes in the absorption coefficients (ap and aɸ), and 87% of the Kd variability. Approximately 80% of the chlorophyll concentration can be explained by the water column spectral reflectance relationship: Rrs(443)/Rrs(555). According to our results, regional chlorophyll estimates from water column bio-optical information were not greatly affected by wind-borne dust transported during the October 1999 Santa Ana events.

Abstract

Challenges associated with global change stressors on ecosystems have prompted calls to improve actionable science, including through boundary‐spanning activities, which aim to build connections and communication between researchers and natural resource practitioners. By synthesizing and translating research and practitioner knowledge, boundary‐spanning activities could support proactive, research‐informed conservation practice, but the success of these efforts is rarely evaluated.

Using repeat survey data from the Northeast Regional Invasive Species and Climate Change (NE RISCC) Management Network, a boundary‐spanning organization, we evaluate whether participating in NE RISCC affected practitioners' knowledge, actions and priorities related to invasive species management under a changing climate.

Our survey results suggest that practitioners who participate in NE RISCC have greater knowledge about invasive species and climate change and are incorporating climate change in more ways into their invasive species management. We also found NE RISCC membership affected the perceived usefulness of informational resources, with NE RISCC members more frequently identifying research syntheses and targeted workshops (both are common products used by NE RISCC to translate science into practice and share manager knowledge) as useful compared to non‐members.

Practitioners who participate in NE RISCC also identified somewhat different research priorities, with non‐members and short‐term members more frequently identifying range‐shifting neonative species and their impacts on native communities as higher priorities compared to long‐term NE RISCC members. NE RISCC research activities and outreach materials have consistently framed range‐shifting neonative species as comparatively low risk, suggesting that this information has influenced practitioner's perception of risk.

Practical implication: Although real‐world impacts of applied ecology are notoriously difficult to quantify, this analysis illustrates that if research results are actively translated, they can affect the knowledge and actions of natural resource practitioners. These impacts illustrate the potential for boundary‐spanning efforts to address other global change challenges to conservation.

Published: October 2024

AbstractPurposeTo characterize 3D‐printed stainless steel metal samples in the presence of an Iridium‐192 source for organ‐at‐risk sparing in gynecologic brachytherapy.MethodsSamples of 3D‐printed stainless steel (5.5 × 5.5 cm2, thickness range 1–5 mm) were embedded in a solid water phantom at varying distances from source catheters. An Ir‐192 brachytherapy source was passed through the phantom and the dose was measured using EBT3 Gafchromic film. The film was initially positioned in the sagittal plane 2 cm away from the catheters, with the metal directly below and then 1 cm from the film. A uniform dose was delivered at the film plane. A second setup measured a depth dose curve in solid water with film in the transverse plane directly above the metal samples. This setup was recreated using Monte Carlo simulations (EGSnrc egs_brachy). Validation between methods was performed with unshielded (solid water only) measurements.ResultsThe planar dose passing through the metal samples (thickness 1–5 mm) at the midpoint between the film and catheters, decreased compared to solid water by 7.4% ± 6.9% to 26.5% ± 5.5%. Dose enhancement on the order of 5% was noted when metal was directly adjacent to the film. The average decrease in depth dose from a single dwell position ranged from 10.0% ± 5.9% (1 mm) to 21.1% ± 5.3% (5 mm) as measured with film, and from 3.8% ± 0.9% (1 mm) to 16.3% ± 0.9% (5 mm) using MC simulation. The average depth dose values were measured using a line width of 2.5 mm for film, and 3 mm for MC simulation, and the measurements generally agree within standard error.ConclusionsThe 3D‐printed metal samples show potential for personalized applicators. Maximum dose reduction of 26.5% ± 5.5% compared to solid water was measured at 2 cm from the source using the 5 mm sample. An outer layer of solid water could potentially be used to reduce dose enhancement due to increased scatter near the metal.

AbstractObjectiveTo systematically evaluate which lesion‐based imaging features and methods allow for the best statistical prediction of poststroke deficits across independent datasets.MethodsWe utilized imaging and clinical data from three independent datasets of patients experiencing acute stroke (N1 = 109, N2 = 638, N3 = 794) to statistically predict acute stroke severity (NIHSS) based on lesion volume, lesion location, and structural and functional disconnection with the lesion location using normative connectomes.ResultsWe found that prediction models trained on small single‐center datasets could perform well using within‐dataset cross‐validation, but results did not generalize to independent datasets (median R2N1 = 0.2%). Performance across independent datasets improved using large single‐center training data (R2N2 = 15.8%) and improved further using multicenter training data (R2N3 = 24.4%). These results were consistent across lesion attributes and prediction models. Including either structural or functional disconnection in the models outperformed prediction based on volume or location alone (P < 0.001, FDR‐corrected).InterpretationWe conclude that (1) prediction performance in independent datasets of patients with acute stroke cannot be inferred from cross‐validated results within a dataset, as performance results obtained via these two methods differed consistently, (2) prediction performance can be improved by training on large and, importantly, multicenter datasets, and (3) structural and functional disconnection allow for improved prediction of acute stroke severity.

AbstractObjectiveCompare the diagnostic characteristics of intraepidermal nerve fiber density (IENFD) and confocal corneal microscopy (CCM) for distal symmetric polyneuropathy (DSP) and small fiber neuropathy (SFN).MethodsParticipants with obesity were recruited from bariatric surgery clinics and testing was performed prior to surgery. DSP and SFN were determined using the Toronto consensus definitions of probable neuropathy. IENFD was assessed from 3 mm punch biopsies of the distal leg and proximal thigh. CCM was performed on both eyes with manual and automated counting. The Michigan Neuropathy Screening Instrument questionnaire (MNSIq) was also completed. Diagnostic capability was determined using areas under the receiver operating characteristics curve (AUC) from logistic regression.ResultsWe enrolled 140 participants (mean [standard deviation [SD]] age: 50.3 years [7.1], 77.1% female, BMI: 44.4 kg/m2 [6.7]). In this population, 22.9% had DSP and 14.3% had SFN. Distal leg IENFD had the largest AUC (95% confidence interval) for DSP (0.78, 0.68–0.89) and SFN (0.85, 0.75–0.96). Proximal thigh IENFD (DSP: AUC: 0.59, 0.48–0.69, SFN: AUC: 0.59, 0.46–0.73) and CCM metrics (DSP: AUC range: 0.55–0.60, SFN: AUC range: 0.45–0.62) had poorer diagnostic capability than distal leg IENFD for DSP/SFN (P < 0.05). MNSIq had similar diagnostic capability to distal leg IENFD for both DSP/SFN (DSP: AUC: 0.76, 0.68–0.85, SFN: AUC: 0.81, 0.73–0.88). More participants (52%) preferred skin biopsies to CCM.InterpretationDistal leg IENFD was the best quantitative measure of DSP/SFN. CCM had poor diagnostic characteristics and fewer patients preferred this test to IENFD. The MNSIq had similar diagnostic characteristics to distal leg IENFD, indicating its value as a diagnostic tool in the clinical setting.Clinical Trial Registrationclinicaltrials.gov: NCT03617185.

Published: October 2024

AbstractObjectiveThe association between gait speed and adverse outcomes after stroke has not been fully illustrated. This study aimed to explore the association of gait speed on long‐term outcomes in minor stroke or transient ischemic attack (TIA).MethodsWe performed a longitudinal study with acute minor stroke or TIA based on a subgroup of the Third China National Stroke Registry data. The gait speed was evaluated using a 10‐meter walking test at discharge and 3 months after the stroke onset. The primary outcomes were poor functional outcomes at 1 year, defined by a modified Rankin Score (mRS) of 2–6. Additional outcomes included all‐cause death, ambulate dependency (mRS score 4–6), cognitive impairment (Montreal Cognitive Assessment <26), stroke recurrence, and composite vascular events.ResultsThe study sample included a total of 1542 stroke patients with a median age of 60 (53–68). At 1‐year follow‐up, 140 (9.20%) patients experienced poor functional outcomes. Faster gait speed at discharge was associated with lower incidence of poor functional outcome (OR = 0.89; 95% CI, 0.84–0.94), cognitive impairment (OR = 0.93; 95% CI, 0.89–0.96), ischemic stroke recurrence (HR = 0.92; 95% CI, 0.87–0.98), and composite vascular events (HR =0.94; 95% CI, 0.89–0.99) at 1 year. Faster gait speed at 3 months was associated with lower incidence of poor functional outcome (OR = 0.90; 95% CI, 0.85–0.95), ambulate dependency (OR = 0.86; 95% CI, 0.77–0.97), and cognitive impairment (OR = 0.92; 95% CI, 0.88–0.95) at 1 year.InterpretationOur findings indicated that slow gait speed after minor stroke or TIA may be an independent predictor for long‐term poor outcomes. Gait speed may be considered as a vital sign during follow‐up in post‐stroke patients.
