A intensificação do comportamento tipo ansiedade induzido por cafeína em Daniorerio(zebrafish) é prevenida pelo tratamento com α-Tocoferol e L-NAME

O crescente consumo de bebidas com elevado teor de cafeína pode resultar no aparecimento de sintomas provenientes do transtorno de ansiedade induzida por essa droga. Atualmente, tem-se utilizado a cafeína como um indutor farmacológico do comportamento tipo ansiedade e essa indução pode facilitar a melhor compreensão da relação entre alterações comportamentais e os mecanismos de ação envolvidos nesse efeito, portanto o presente trabalho propôs que a via nitrérgica poderia ser um mecanismo chave para explicar os efeitos comportamentais produzidos pela cafeína e que esses efeitos poderiam ser revertidos por um antioxidante, logo, no presente trabalho nós tivemos como objetivo avaliar o possível efeito do L-NAME e do α-tocoferol no comportamento tipo ansiedade ampliado pela cafeína nos testes de preferência claro/escuro (PCE) e distribuição vertical eliciada pela novidade (DVN) em Daniorerio. Foram utilizados peixes da espécie Daniorerio(n=178) subdivididos nos seguintes grupos experimentais: SAL – salina 0,9%; CAF – cafeína 100 mg/kg; DMSO – dimetilsulfóxido 0,1%; L-NAME - (N -Nitro-L-arginina-metil éster hidrocloreto) 10 mg/kg; TF – α-tocoferol 1 mg/kg (receberam apenas uma injeção por i.p); SAL + SAL; DMSO + SAL; SAL + CAF; L-NAME + SAL; L-NAME +CAF; TF + CAF (receberam duas injeções seguidas, uma injeção de cada substância na forma de cotratamento, por i.p). Os animais foram submetidos ao teste de preferência claro/escuro e de distribuição vertical eliciada pela novidade. Todos os testes foram filmados e os vídeos foram avaliados utilizando o X-PLO-RAT. Os dados foram expressos em média ± erro padrão. Foi aplicado o teste de normalidade utilizando o teste Shapiro-Wilk e o teste paramétrico ANOVA de uma via com pós-teste Tukey, considerando significativos valores com p<0,05. Nós demonstramos que o α-tocoferol na dose de 1 mg/kg reverteu todos os parâmetros do comportamento tipo ansiedade ampliado pela cafeína nos testes de PCE e do DVN e esse efeito foi semelhante ao observado quando administrado um inibidor da enzima óxido nítrico sintase (NOS), L-NAME. Portanto, o presente trabalho demonstrou pela primeira vez que o efeito comportamental ampliado pela cafeína no teste escotáxico e no DVN pode ser modulado pelo sistema nitrérgico e que o α-tocoferol reverte esse efeito comportamental induzido pela cafeína de forma total.

Análise acústica da relação acento versus entoação no português falado em Mocajuba: contribuições para o Projeto Amper-Norte

A presente Dissertação faz parte do projeto Atlas Prosódico Multimédia da Região do Norte do Brasil (AMPER-NORTE) e que, por sua vez, está vinculado ao projeto Atlas Prosódico Multimedia do Português (AMPER-POR). Seu objetivo principal é contribuir com o projeto AMPER-NORTE, com a caracterização da variação prosódica dialetal do português falado na zona urbana do município de Mocajuba (PA). Os procedimentos metodológicos adotados foram previamente estabelecidos pelo projeto AMPER. O corpus foi constituído com uma amostra de fala de seis informantes, três do gênero masculino e três do gênero feminino; uma mulher (BF51) e um homem (BF52) do ensino Fundamental, uma mulher (BF53) e um homem (BF54) do ensino Médio, uma mulher (BF55) e um homem (BF56) do ensino Superior, da variedade do português falado em Mocajuba. O corpus do município é formado por 102 frases, do tipo SVC (sujeito + verbo + complemento), com complemento adjetival e indicadores de lugar. Cada sentença foi repetida seis vezes, totalizando 612 frases por informante. A análise foi feita a partir de dados relativos aos seis informantes, para tanto foram selecionadas 42 frases, sendo 21 afirmativas e 21 interrogativas totais com sintagmas nominais simples ou compostos, elas foram selecionadas de modo a contemplar as três pautas acentuais do português apresentando um total de 14 oxítonas, 14 paroxítonas e 14 proparoxítonas. A análise acústica das vogais foi feita em seis etapas e os resultados mostram que os parâmetros físicos acústicos de freqüência fundamental (F0) e duração (ms) demonstraram resultados relevantes para esta análise, confirmando os referidos parâmetros como complementares na distinção das modalidades frasais nesta variedade em estudo. A F0 torna-se relevante, pelo movimento em formato de pinça, que ocorre preferencialmente na sílaba tônica, do vocábulo-alvo, nominal, nas três pautas acentuais e a duração mostra que as pautas acentuais (oxítona, paroxítona e proparoxítona) registraram valores inversamente proporcionais, confirmando-se como um parâmetro distintivo. Na intensidade, não se observou distinção suficientemente satisfatória para confirmá-la como complementar à F0 e ms na variedade do português falado em Mocajuba.

Syndrome in Question

A 48-year-old male patient with chronic alcoholism presented with a soft, bulky, asymptomatic, and slow-growing mass in the posterior region of the neck, as well as nodules in the deltoid region and posterior triangle of the sternocleidomastoid muscle. Needle aspiration confirmed the diagnosis of lipoma. Multiple symmetric lipomatosis (Madelung's disease) is a rare proliferation of adipocytes, of unknown etiology, most common in middle-aged men and mainly associated with alcoholism. It predominantly affects the neck and upper trunk, causing compressive symptoms or a imparting a pseudoathletic appearance. Surgical resection or liposuction is the most effective treatment, despite frequent recurrence.

Concordance between Stages of Behavior Change Questionnaire and IPAQ

A low rate of physical activity (PA) participation is observed worldwide. The identification of feasible and reliable instruments able to accurately measuring PA and help in the development of interventions to promote PA are necessary. This study aimed to analyze the concordance between the Stages of Behavior Change Questionnaire (SBCQ) and the International Physical Activity Questionnaire (IPAQ long-version) in assessing adult leisure-time physical activity (LTPA). A total of 1.588 adults completed the IPAQ to assess LTPA and the participants who performed more than 10 min/week were classified in active individuals. Using the SBCQ, active individuals were those classified in the action or maintenance stage and inactive individuals were those classified in the precontemplation, contemplation or preparation stage. The concordance between SBCQ and IPAQ was found to be 0.80. Separated by gender, it was observed a concordance between the two instruments of 0.82 for women, and 0.77 for men. Regarding age group, it was found to be 0.81 for young and middle-aged adults, and 0.77 for older people. The SBCQ presented a very good concordance with IPAQ to assess LTPA.

STATE REGISTRATION AND LICENSING REGULATIONS: A NEW PROGRAM (OHIO)

We enacted a bill in Ohio this year, Senate Bill 445, that has to do with the application of pesticides. It is a very wide bill as you would normally look at it with most of the meat going to come from the regulations that are presently being written into it. In other words, the framework was developed and accepted by the two houses in our state legislature and empowered the Director of Agriculture to establish the regulations or the so-called teeth to this bill. The governor signed the bill in June and it became effective in September. The committees as of this time are meeting to develop philosophies and regulations that will be promulgated and brought into hearings and sifted through, and eventually, with a target date of December of this year, (1970), brought to the Director of Agriculture's office for acceptance. There is a committee established for rodent and bird control which is very well represented by our industry here in Ohio. John Beck (Rose Exterminator Company) is the chairman of the committee, William B. Jackson (Bowling Green State University) and Robert Yaeger (Cincinnati) are also on the committee. The important feature of this new law, in terms of pest control operators, is the examinations that will be required. We operators and our service people will both be tested and licensed, if sufficient proficiency is demonstrated on the tests. For your information they use a little different terminology in the bill than we in the industry normally use. We think of an applicator in the industry as service people. In the bill an applicator is defined as an operator. Therefore in reading the law the word operator means the man who does the job, the service man. Just the reverse is true in the industry. We think of the operator as the man who owns or manages the company while these people are referred to in the bill as applicators. The Bill calls for the development of schools for the training of our people throughout the state. Those of us who are in bird control should begin to prepare ourselves to meet this request, to be available for the schooling, have our people available for the schooling, and give this program all the co-operation that we can.

Calorie restriction increases cerebral mitochondrial respiratory capacity in a NO center dot-mediated mechanism: Impact on neuronal survival

Calorie restriction (CR) enhances animal life span and prevents age-related diseases, including neurological decline. Recent evidence suggests that a mechanism involved in CR-induced life-span extension is NO-stimulated mitochondrial biogenesis. We examine here the effects of CR on brain mitochondrial content. CR increased eNOS and nNOS and the content of mitochondria] proteins (cytochrome c oxidase, citrate synthase, and mitofusin) in the brain. Furthermore, we established an in vitro system to study the neurological effects of CR using serum extracted from animals on this diet. In cultured neurons, CR serum enhanced nNOS expression and increased levels of nitrite (a NO product). CR serum also enhanced the levels of cytochrome c oxidase and increased citrate synthase activity and respiratory rates in neurons. CR serum effects were inhibited by L-NAME and mimicked by the NO donor SNAP. Furthermore, both CR sera and SNAP were capable of improving neuronal survival. Overall, our results indicate that CR increases mitochondrial biogenesis in a NO-mediated manner, resulting in enhanced reserve respiratory capacity and improved survival in neurons.

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

Meditation training increases brain efficiency in an attention task

Meditation is a mental training, which involves attention and the ability to maintain focus on a particular object. In this study we have applied a specific attentional task to simply measure the performance of the participants with different levels of meditation experience, rather than evaluating meditation practice per se or task performance during meditation. Our objective was to evaluate the performance of regular meditators and non-meditators during an fMRI adapted Stroop Word-Colour Task (SWCT), which requires attention and impulse control, using a block design paradigm. We selected 20 right-handed regular meditators and 19 non-meditators matched for age, years of education and gender. Participants had to choose the colour (red, blue or green) of single words presented visually in three conditions: congruent, neutral and incongruent. Non-meditators showed greater activity than meditators in the right medial frontal, middle temporal, precentral and postcentral gyri and the lentiform nucleus during the incongruent conditions. No regions were more activated in meditators relative to non-meditators in the same comparison. Non-meditators showed an increased pattern of brain activation relative to regular meditators under the same behavioural performance level. This suggests that meditation training improves efficiency, possibly via improved sustained attention and impulse control. (C) 2011 Elsevier Inc. All rights reserved.

Obsessive-compulsive symptom dimensions correlate to specific gray matter volumes in treatment-naive patients

Background: Clinical and sociodemographic findings have supported that OCD is heterogeneous and composed of multiple potentially overlapping and stable symptom dimensions. Previous neuroimaging investigations have correlated different patterns of OCD dimension scores and gray matter (GM) volumes. Despite their relevant contribution, some methodological limitations, such as patient's previous medication intake, may have contributed to inconsistent findings. Method: Voxel-based morphometry was used to investigate correlations between regional GM volumes and symptom dimensions severity scores in a sample of 38 treatment-naive OCD patients. Several standardized instruments were applied, including an interview exclusively developed for assessing symptom dimensions severity (DY-BOCS). Results: Scores on the "aggression" dimension were positively correlated with GM volumes in lateral parietal cortex in both hemispheres and negatively correlated with bilateral insula, left putamen and left inferior OFC. Scores on the "sexual/religious" dimension were positively correlated with GM volumes within the right middle lateral OFC and right DLPFC and negatively correlated with bilateral ACC. Scores on the "hoarding" dimension were positively correlated with GM volumes in the left superior lateral OFC and negatively correlated in the right parahippocampal gyrus. No significant correlations between GM volumes and the "contamination" or "symmetry" dimensions were found. Conclusions: Building upon preexisting findings, our data with treatment-naive OCD patients have demonstrated distinct GM substrates implicated in both cognitive and emotion processing across different OCS dimensions.
