Imagens em diálogo: cultura visual no Brasil e México em perspectiva comparada

O objetivo deste artigo é averiguar a circulação de imagens e o surgimento de uma cultura visual política entre o México e o Brasil entre as décadas de 1920 e 1930. Busco examinar em especial como se constituíram repertórios visuais comuns entre os dois países, tanto na produção de imagens carregadas com uma retórica do engajamento político como de algumas imagens que num primeiro olhar poderiam passar por descompromissadas, mas que contribuíram para a construção do imaginário político. Embora minha intenção não seja de uma análise exaustiva, procuraremos averiguar diferentes suportes imagéticos, como as fotografias estampadas na imprensa diária assim como nas revistas ilustradas, cartazes, gravuras e demais expressões artísticas que subsidiem essa circulação de idéias estéticas e políticas entre os dois países. Parto da hipótese de que, apesar das dificuldades de intercâmbios existentes entre os dois países (língua, distância e falta de um contato maior entre seus artistas e intelectuais), ocorreu um intercâmbio de propostas políticas e culturais, principalmente entre redes de sociabilidade de artistas marcadamente no âmbito da esquerda política.

Efeito da intervenção terapêutica ocupacional junto a crianças com déficts de percepção visual, coordenação motora e integração visuo-motora

To students with special educational needs participate actively at school are required effective and systematic investment, involving the school community as a whole. The occupational therapist is one of the professionals who can facilitate this student inclusion process. This study aimed to discuss the occupational therapy intervention effects with two disability children with deficits in visual perceptual skills, motor coordination and visual motor integration, that was included in regular education. The Beery-Buktenica Developmental Test of Visual Motor Integration was use to evaluate visual perceptual skills, motor coordination and visual-motor integration. Because the deficits presented in the functions investigates was identified the need of an occupational therapy intervention program designed to improve the performance in theses functions. After the program, the test was reapplied. The results pointed to an improvement of all functions considered deficient. These results highlight to the training importance to improve the performance in abilities evaluated.

Fragmento d'alma

Fragmento D' Alma is an artistic research that part of a poetic tale through an initial charge of dawn one fantastic universe where words have life and willingly. The work includes sculptural works in order to interpret through the use of allegory situations of the tale in the form of sculptural compositions considering one or more characters in the story. In the sculptural work, I tried figuring the relations tale as my interpretations and poetic, so I sought theoretical studies of allegory after noting my affinity with the theme to contribute to the relationship text and image set in my work. I also sought to understand the relationships that the text played with sculptural work, so the chances that I could address this through dialogue between text and image. The studies collected through surveys pointed allegory by João Adolfo Hansen, as well as in various artistic and visual references present in my repertoire, such as the Baroque sculpture of Bernini, the performances of Berna Reale and literature of Neil Gaiman, contributed in this research to the development of my creative process during the preparation of this research work of art, making the complexity of the relationship between textual production and poetic sculptural three-dimensional, also became a concern and an integral theme of my work and my reflections presented here. Therefore, I conclude based on my own experience in this work, the artistic research inspired allegory might contribute to the development of my creative process during the preparation of this artwork, besides assigning relations between textual production and poetic dimensional sculpture

Comparison of frequency and time domain electromyography parameters in women with patellofemoral pain

Despite its high incidence, patellofemoral pain etiology remains unclear. No prior study has compared surface electromyography frequency domain parameters and surface electromyography time domain variables, which have been used as a classic analysis of patellofemoral pain. Thirty one women with patellofemoral pain and twenty eight pain-free women were recruited. Each participant was asked to descend a seven step staircase and data from five successful trials were collected. During the task, the vastus medialis and vastus lateralis muscle activities were monitored by surface electromyography. The data were processed and analyzed in four variables of the frequency domain (median frequency, low, medium and high frequency bands) and three time domain variables (Automatic, Cross-correlation and Visual Onset between the vastus medialis and vastus lateralis muscles). Reliability, Receiver Operating Characteristic curves and regression models were performed. The medium frequency band was the most reliable variable and different between the groups for both muscles, also demonstrated the best values of sensitivity and sensibility, 72% and 69% for the vastus medialis and 68% and 62% for the vastus lateralis, respectively. The frequency variables predicted the pain of individuals with patellofemoral pain, 26% for the vastus medialis and 20% for the vastus lateralis, being better than the time variables, which achieved only 7%. The frequency domain parameters presented greater reliability, diagnostic accuracy and capacity to predict pain than the time domain variables during stair descent and might be a useful tool to diagnose individuals with patellofemoral pain.

Predator and Heterospecific Stimuli Alter Behavior in Cattle

Wild and domestic ungulates modify their behavior in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores.We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory and visual), and a control (no stimuli) to experimentally test for differences in behavior of cattle (Bos taurus) raised in Arizona. We measured (1) vigilance, (2) foraging rates, (3) giving up density (GUD) of high quality foods and (4) time spent in high quality forage locations in response to location of stimuli treatments. In general, we found a consistent pattern in that wolf and deer treatments caused disparate results in all 4 response variables. Wolf stimuli significantly increased cattle vigilance and decreased cattle foraging rates; conversely, deer stimuli significantly increased cattle foraging rate and increased cattle use of high quality forage areas containing stimuli. Mountain lion stimuli did not significantly impact any of the 4 response variables. Our findings suggest that domestic herbivores react to predatory stimuli, can differentiate between stimuli representing two predatory species, and suggest that cattle may reduce antipredatory behaviour when near heterospecifics.

The combined effect of acupuncture and Tanacetum parthenium on quality of life in women with headache: randomised study

Background The aim of the present study was to investigate the efficacy and tolerability of acupuncture (AC), Tanacetum (TAN) or combined treatment on quality of life in women with chronic migraine (CM). Methods A total of 69 women volunteers were randomly divided into 3 groups: AC, acupuncture administered in 20 sessions over 10 weeks (n=22); TAN, at 150 mg/day (n=23); and AC+TAN (n=23). The primary outcome was Short-Form 36 (SF-36) quality of life assessment score. Secondary outcomes included the Migraine Disability Assessment (MIDAS) and visual analogue scale (VAS) score experienced after randomisation. Results AC+TAN was statistically significantly more effective than AC or TAN alone in overall health-related quality of life (SF-36; p<0.05), on MIDAS score (-35.1 (10.6) AC vs -24.8 (11.7) TAN vs -42.5 (9.8) AC+TAN; p<0.05) and in reducing the mean score of pain on VAS (-5.6 (2.4) AC vs -3.7 (2.1) TAN vs -6.4 (3.1) AC+TAN; p<0.05). Conclusions The present work shows an improvement of the quality of life and better analgesic effect of acupuncture combined with TAN treatment on migraine pain in women when compared with acupuncture or TAN alone.

Quantification of Retinal Neural Loss in Patients with Neuromyelitis Optica and Multiple Sclerosis with or without Optic Neuritis Using Fourier-Domain Optical Coherence Tomography

PURPOSE. We compared retinal nerve fiber layer (RNFL) and macular thickness measurements in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO) with or without a history of optic neuritis, and in controls using Fourier-domain (FD) optical coherence tomography (OCT). METHODS. Patients with MS (n = 60), NMO (n = 33), longitudinal extensive transverse myelitis (LETM, n = 28) and healthy controls (n = 41) underwent ophthalmic examination, including automated perimetry, and FD-OCT RNFL and macular thickness measurements. Five groups of eyes were compared: MS with or without previous optic neuritis, NMO, LETM, and controls. Correlation between OCT and visual field (VF) findings was investigated. RESULTS. With regard to most parameters, RNFL and macular thickness measurements were significantly smaller in eyes of each group of patients compared to controls. MS eyes with optic neuritis did not differ significantly from MS eyes without optic neuritis, but measurements were smaller in NMO eyes than in all other groups. RNFL (but not macular thickness) measurements were significantly smaller in LETM eyes than in controls. While OCT abnormalities were correlated significantly with VF loss in NMO/LETM and MS, the correlation was much stronger in the former. CONCLUSIONS. Although FD-OCT RNFL and macular thickness measurements can reveal subclinical or optic neuritis-related abnormalities in NMO-spectrum and MS patients, abnormalities are predominant in the macula of MS patients and in RFNL measurements in NMO patients. The correlation between OCT and VF abnormalities was stronger in NMO than in MS, suggesting the two conditions differ regarding structural and functional damage.

GALAXIES BEHIND THE GALACTIC PLANE: FIRST RESULTS AND PERSPECTIVES FROM THE VVV SURVEY

VISTA Variables in the Via Lactea (VVV) is an ESO variability survey that is performing observations in near-infrared bands (ZY JHK(s)) toward the Galactic bulge and part of the disk with the completeness limits at least 3 mag deeper than Two Micron All Sky Survey. In the present work, we searched in the VVV survey data for background galaxies near the Galactic plane using ZY JHK(s) photometry that covers 1.636 deg(2). We identified 204 new galaxy candidates by analyzing colors, sizes, and visual inspection of multi-band (ZY JHK(s)) images. The galaxy candidate colors were also compared with the predicted ones by star count models considering a more realistic extinction model at the same completeness limits observed by VVV. A comparison of the galaxy candidates with the expected one by Millennium simulations is also presented. Our results increase the number density of known galaxies behind the Milky Way by more than one order of magnitude. A catalog with galaxy properties including ellipticity, Petrosian radii, and ZY JHK(s) magnitudes is provided, as well as comparisons of the results with other surveys of galaxies toward the Galactic plane.

Cough and dyspnea during bronchoconstriction: comparison of different stimuli

Abstract Background Bronchial challenge tests are used to evaluate bronchial responsiveness in diagnosis and follow-up of asthmatic patients. Challenge induced cough has increasingly been recognized as a valuable diagnostic tool. Various stimuli and protocols have been employed. The aim of this study was to compare cough and dyspnea intensity induced by different stimuli. Methods Twenty asthmatic patients underwent challenge tests with methacholine, bradykinin and exercise. Cough was counted during challenge tests. Dyspnea was assessed by modified Borg scale and visual analogue scale. Statistical comparisons were performed by linear mixed-effects model. Results For cough evaluation, bradykinin was the most potent trigger (p < 0.01). In terms of dyspnea measured by Borg scale, there were no differences among stimuli (p > 0.05). By visual analogue scale, bradykinin induced more dyspnea than other stimuli (p ≤ 0.04). Conclusion Bradykinin seems to be the most suitable stimulus for bronchial challenge tests intended for measuring cough in association with bronchoconstriction.
