Ballroom dance and Forro are part of Brazilian culture, and Xote and Baiao are part of Forro. The aim of this study was to diagramate the dances Xote and Baiao they are danced inside São Paulo State and to describe rhythmly these movements. It was observed and filmed several college couples dancing Xote and Baiao for analysis and description of the movements of the dances, by a discursive way and by diagrams. It was identified two basic structures ("Lateral Basic Step" and "Forward and Back Basic Step"), and variation steps "Open" and "Change of places with Turn", very used by couples.

Controle postural em pacientes com lesão do ligamento cruzado anterior

A lesão do ligamento cruzado anterior (LCA) do joelho acarreta alterações somatosensoriais em função da perda de informações provenientes dos mecanorreceptores presentes no LCA. Esses receptores constituem importante fonte de informação sensorial, afetando o desempenho de vários atos motores, dentre os quais o controle postural. O estudo objetivou analisar o controle postural de indivíduos com joelhos normais e com lesão unilateral do LCA. Participaram 15 voluntários com lesão do LCA (grupo lesado) e 15 voluntários com joelhos normais (grupo controle). O controle postural foi analisado por plataforma de força, sendo o voluntário instruído a assumir a situação experimental em apoio unipodal direito e esquerdo, posicionado no centro da plataforma de modo estático e com os olhos fechados. A plataforma de força forneceu informações de forças e momentos no eixo vertical e horizontal, a partir das quais foi obtida a área de deslocamento do centro de pressão nas direções ântero-posterior e médio-lateral. Os resultados mostram que indivíduos com lesão do LCA apresentaram maior amplitude média de oscilação comparados aos do grupo controle, sugerindo que o deficit no controle postural seja devido à perda de informações proprioceptivas nos indivíduos com LCA. Esses resultados têm implicações para a abordagem clínica de indivíduos com lesão do LCA.

Índices fisiológicos associados com a performance aeróbia em corredores de endurance: efeitos da duração da prova

O objetivo deste estudo foi analisar a validade do consumo máximo de oxigênio (VO2max), da velocidade correspondente ao VO2max (vVO2max), do tempo de exaustão na vVO2max (Tlim), da economia de corrida (EC) e do limiar anaeróbio (LAn) para a predição da performance de atletas de endurance. Quatorze corredores de endurance (33,4 ± 4,4 anos; 62,7 ± 4,3kg; 166,1 ± 5,0cm; VO2max = 60,4 ± 5,9ml.kg-1.min-1) realizaram os seguintes testes: a) competição simulada nas distâncias de 1.500 e 5.000m. e; b) testes de laboratório para a determinação do VO2max, vVO2max, EC, LAn e Tlim na intensidades de 100% vVO2max. As velocidades (km/h) da vVO2max (18,7 ± 0,8), LAn (17,3 ± 1,1) v1.500m (19,9 ± 0,8) e v5.000m (17,9 ± 0,9) foram significantemente diferentes. A regressão múltipla stepwise revelou que o LAn foi o único preditor da performance da v5.000m, explicando 50% da variação desta performance. Para a v1.500m, o Tlim e a vVO2max explicaram 88% da variação da performance. Com base em nossos resultados, pode-se concluir que a validade dos índices fisiológicos (VO2max, vVO2max, Tlim, EC e LAn), para a predição da performance aeróbia de atletas de endurance, é dependente da distância da prova (1.500 x 5.000m) analisada.

Adubação foliar. I. Épocas de aplicação de fósforo na cultura da soja

The search for new alternatives in order to increase soybeans productivity has been constant objective of researchers and farmers. The crop responses to phosphorus application in the soil are well defined, being this nutrient very important on its development and yield. The leaf fertilization on this crop appears as a new rationale option, mainly when the plant nutrient levels are low. So, this work aimed to study the effect of phosphorus leaf fertilization, applied at different plant stage, including: V5, R1, R4, V5 + R1, V5 + R4, R1 + R4, V5 + R1 + R4, V5 + R1 + R4 + R6 and test plot. The experiment was installed in a soybeans crop, Monarca cultivar, at Palmital Farm, Ijaci county, Minas Gerais state, Brazil, using a totally randomized design, with 9 treatments and 3 replications. The chelate Quimifol P30 in liquid form with 30% of the nutrient soluble in CNA + water in the, with doses of 21. ha(-1), was utilized as phosphorus source, using the applications performed with a constant pressure CO(2)-nebulizer. The different epochs of phosphorous application significantly altered the grains yield, proportioning significant increases, up to 16% for the V5, V5 + R1, V5 + R4, V5 + R1 + R4, V5 + R1 + R4 + R6 epochs, when compared to the test plot, clearly expressing the positive effect of these applications at V5 stage. The plant height, first legume insertion, and lodging index characteristics were not significantly altered by the different epochs evaluated. It was observed significant response for the nutrient leaf amounts only in the case of K and Zn indices, exclusively in the V5 + R4, and in the V5, V5 + R1 and V5 + R1 + R4 + R6 treatments, respectively.

Photoluminescence in disordered Zn2TiO4

In this work, the polymeric precursor method Was used to obtain disordered Zn2TiO4 powders, either Undoped or doped with Sn4+, Cr3+ and V5+, to be applied its photoluininescent material. The characterization was undertaken by means of thermal analysis (TG and DTA), X-ray diffraction (XRD), infrared spectroscopy (IR) and photoluminescence (PL). Previous works stated that titanate octahedra containing a short Ti-O distance show efficient luminescence at roorn temperature if these octahedra are isolated from each other. In the present work, the phenomenon was observed in condensed octahedra, sharing edges. The room temperature PL noticed in undoped Zn2TiO4 had its intensity increased by the dopant addition-the increase was of about 300% for V5+ doping 400% for Cr3+ and 800% for Sn4+.

Morphological characterization of the venom secretory epidermal cells in the stinger of marine and freshwater stingrays

Marine and freshwater stingrays are characterized by the presence of one to three mineralized serrated stingers on the tail, which are covered by epidermal cells secreting venom. When these animals are dorsally touched, the stinger can be introduced into the aggressor by a whip reflex mechanism of the tail, causing severe mechanical injuries and inoculating the venom. Accidents in humans are frequent causing intense local pain, oedema and erythema. Bacterial secondary infection is also common. In addition, injuries involving freshwater stingrays frequently cause a persistent cutaneous necrosis. The exact localization of the venom secretory epidermal cells in the stinger is controversial, but it is known that it is preferentially located in the ventrolateral grooves. A comparative morphological analysis of the stinger epidermal tissue of different marine and freshwater Brazilian stingray species was carried out. The results indicate that in freshwater species there is a larger number of protein secretory cells, of two different types, spread over the whole stinger epidermis, while in marine species the protein secretory cells are located only around or inside the stinger ventrolateral grooves. These differences between the stingers of the two groups can justify the more severe envenomation accidents with the freshwater species when compared with the marine species. (c) 2007 Elsevier Ltd.

Inoculação de sementes com bactéria diazotrófica e aplicação de nitrogênio em cobertura e foliar em milho

Considering the importance of nitrogen management and its biological fixation with diazotrophic bacteria, this study was carried out aiming to evaluate the agronomic performance of maize, in response to seed inoculation with Azospirillum brasilense and nitrogen application in side-dressing and leaf. The experiment was conducted in Selvíria, Mato Grosso of Sul State, Brazil, during the growing season 2010/2011, on a clayey Rhodic Haplustox (20° 20' S and 51° 24' W, with altitude of 340 m). Sixteen treatments were established with four replications, in randomized blocks with the combination of the factors A. brasilense (with and without inoculante), nitrogen rate (0 and 90 kg ha-1, in V5 growth stage) and urea leaf application (0, 4, 8 and 12%: application in V5 and V8 growth stage). The maize hybrid used was the DKB 390 YG®, sowed in the row spacing of 0.9 m. Parameters measured were productive and morphological components of culture and crop yield. Increase in maize yield by seed inoculation with A. brasilense was observed. The application of 90 kg ha -1 of nitrogen in side-dressing provided higher chlorophyll leaf index, stalk diameter and prolificacy, however, the yield not was increased. The application of urea leaf did not agronomic efficiency and, therefore, should not be used as the unique form of supply and alternative to nitrogen addition to crop.

In vivo assessment of intratumoral aspirin injection to treat hepatic tumors

AIM: To study the antineoplastic efficacy of 10% aspirin intralesional injection on VX2 hepatic tumors in a rabbit model. METHODS: Thirty-two male rabbits (age: 6-9 wk; body weight: 1700-2500 g) were inoculated with VX2 hepatic tumor cells (104 cells/rabbit) via supraumbilical median laparotomy. On day 4 post-implantation, when the tumors were about 1 cm in diameter, the rabbits were randomly divided into the following groups (n = 8 each group) to assess early (24 h) and late (7 d) antineoplastic effects of intratumoral injection of 10% bicarbonate aspirin solution (experimental groups) in comparison to intratumoral injection of physiological saline solution (control groups): group 1, 24 h control; group 2, 24 h experimental; group 3, 7 d control; group 4, 7 d experimental. The serum biochemistry profile (measurements of glycemia, alkaline phosphatase, gamma-glutamyl transferase, aspartate aminotransferase, and alanine aminotransferase) and body weight measurements were obtained for all animals at the following time points: D0, before tumor implant; D4, day of treatment; D5, day of sacrifice for groups 1 and 2; D11, day of sacrifice for groups 3 and 4. Gross assessments of the abdominal and thoracic cavities were carried out upon sacrifice. The resected liver tissues, including hepatic tumors, were qualitatively (general morphology, signs of necrosis) and quantitatively (tumor area) assessed by histopathological analysis. RESULTS: Gross examination showed no alterations, besides the left hepatic lobe tumors, had occurred in the thoracic and abdominal cavities of any animal at any time point evaluated. However, the features of the tumor foci were distinctive between the groups. Compared to the control groups, which showed normal unabated tumor progression, the aspirin-treated groups showed imprecise but limited tumor boundaries and a general red-white coloration (indicating hemorrhaging) at 24 h post-treatment, and development of yellow-white areas of a cicatricial aspect at 7 d after treatment. At all time points evaluated, all except one biochemical parameters tested within the reference range (P > 0.05); a significant increase was detected in the alkaline phosphatase level of the control group 3 on D11 (P < 0.05). At 24 h post-treatment, the aspirintreated groups showed extensive coagulation necrosis accompanied by a remarkable absence of viable tumor foci; at 7 d after treatment, the tumors had completely disappeared in these animals and fibrous necrotic nodules had developed. In contrast, throughout the study course, the tumors of the control groups remained unchanged, showing tumor nodules without necrosis at the time point corresponding to 24 h post-treatment and increased amounts of tumor nodules at the time point corresponding to 7 d post-treatment. Quantitative analysis of the remaining tumor area revealed that the aspirin-treated groups had significantly smaller tumor foci at 24 h post-treatment (8.5% ± 0.7%) andat 7 d after treatment (11.0% ± 4.2%), compared to those in the control groups (24 h: 98.5% ± 1.5% and 7 d: 94.0% ± 2.7%; both, P < 0.005). CONCLUSION: Intralesional injection of a 10% aspirin solution causes destruction of VX2 hepatic tumors in rabbits without evidence of relapse at 7 d after treatment administration. © 2013 Baishideng.
