O tipo de exercício, a intensidade e a frequência são fatores importantes para produzir mudanças na velocidade de andar. O objetivo do estudo foi comparar os efeitos de diferentes tipos de exercício nos parâmetros cinemáticos do andar de idosas, considerando as características antropométricas, a capacidade funcional e o nível de atividade física. Participaram do estudo 56 idosas que foram agrupadas de acordo com o envolvimento, a mais de seis meses, na prática específica de uma atividade: dança (n = 10), musculação (n = 10), hidroginástica (n = 12) e caminhada (n = 11). Além disso, um grupo de idosas inativas (n = 13), sem envolvimento em atividade física regular por pelo menos dois meses, também participou do estudo. Foram mensurados o nível de atividade física (Questionário de Baecke), a capacidade funcional (Bateria da AAHPERD) e os parâmetros cinemáticos do andar (comprimento da passada e do passo, duração e velocidade da passada, cadência e duração das fases de suporte simples, balanço e duplo suporte). Os resultados revelaram que o nível de atividade física do grupo Controle foi diferente dos demais grupos que praticam atividades físicas. em relação à capacidade funcional, apenas o componente força apresentou diferenças entre os grupos, indicando que o grupo Controle difere do grupo musculação. Quanto às variáveis do andar, o grupo Controle foi estatisticamente diferente apenas do grupo dança, tanto no comprimento do passo como no comprimento da passada. Pode-se concluir que a capacidade funcional e os parâmetros do andar dos idosos ativos e sedentários apresentam poucas diferenças

INTRODUÇÃO: Os leiomiomas são neoplasias benignas do músculo liso que ocorrem mais comumente nos tratos geniturinário e gastrintestinal, entretanto são raros na cavidade bucal, na qual provavelmente a maioria desses tumores tem sua origem a partir de músculo liso vascular. OBJETIVOS: Relatar dois casos com história clínica semelhante, confrontando seus aspectos com aqueles encontrados na literatura. RELATO DOS CASOS: Dois casos de mulheres na quinta e sexta décadas de vida apresentando nódulo submucoso em ventre lingual. Após exame microscópico que revelou numerosos vasos sangüíneos entremeados a células fusiformes, com núcleos ovalados ou alongados, e exame imuno-histoquímico com positividade para actina de músculo liso nos dois casos, o diagnóstico final foi leiomioma vascular. CONCLUSÃO: O estudo do leiomioma vascular bucal é de extrema importância devido à raridade e semelhança desse com outras lesões da cavidade bucal. A análise imuno-histoquímica é importante para o diagnóstico final do leiomioma.

CONTEXTO: A síndrome do músculo piriforme pode ter como causa a passagem anormal do nervo ciático ou de uma de suas partes pelo ventre do músculo piriforme. OBJETIVO: Analisar as relações anatômicas e métricas entre o músculo piriforme e o nervo ciático, contribuindo com o conhecimento anátomo-clínico da região glútea. MÉTODO: Foram utilizados 20 cadáveres adultos de ambos os sexos. O nervo ciático e o músculo piriforme foram dissecados, medidos e fotodocumentados. RESULTADOS: Observou-se que 85% das 40 regiões glúteas apresentaram o nervo como tronco único, passando pela borda inferior do músculo piriforme, e 15% mostraram uma variação bilateral, caracterizada pela passagem do nervo fibular comum através do músculo piriforme. Os dados obtidos não revelaram diferenças estatisticamente significantes.

Larvae of an estuarine grapsid crab Chasmagnathus granulata Dana 1851, from temperate and subtropical regions of South America, were reared in seawater (32 ‰) at five different constant temperatures (12, 15, 18, 21, 24 °C). Complete larval development from hatching (Zoea I) to metamorphosis (Crab I) occurred in a range from 15 to 24 °C. Highest survival (60% to the first juvenile stage) was observed at 18°C, while all larvae reared at 12°C died before metamorphosis. The duration of development (D) decreased with increasing temperature (T). This relationship is described for all larval stages as a power function (linear regressions after logarithmic transformation of both D and T). The temperature-dependence of the instantaneous developmental rate (D-1) is compared among larval stages and temperatures using the Q10 coefficient (van't Hoff's equation). Through all four zoeal stages, this index tends to increase during development and to decrease with increasing T (comparing ranges 12-18, 15-21, 18-24 °C). In the Megalopa, low Q10 values were found in the range from 15 to 24 °C. In another series of experiments, larvae were reared at constant 18°C and their dry weight (W) and respiratory response to changes in T were measured in all successive stages during the intermoult period (stage C) of the moulting cycle. Both individual and weight-specific respiration (R, QO2) increased exponentially with increasing T. At each temperature, R increased significantly during growth and development through successive larval stages. No significantly different QO2 values were found in the first three zoeal stages, while a significant decrease with increasing W occurred in the Zoea IV and Megalopa. As in the temperature-dependence of D, the respiratory response to changes in temperature (Q10) depends on both the temperature range and the developmental stage, however, with different patterns. In the zoeal stages, the respiratory Q10 was minimum (1.7-2.2) at low temperatures (12-18 °C), but maximum (2.2-3.0) at 18-24 °C. The Megalopa, in contrast, showed a stronger metabolic response in the lower than in the upper temperature range (Q10 = 2.8 and 1.7, respectively). We interpret this pattern as an adaptation to a sequence of temperature conditions that should typically be encountered by C. granulata larvae during their ontogenetic migrations: hatching in and subsequent export from shallow estuarine lagoons, zoeal development in coastal marine waters, which are on average cooler, return in the Megalopa stage to warm lagoons. We thus propose that high metabolic sensitivity to changes in temperature may serve as a signal stimulating larval migration, so that the zoeae should tend to leave warm estuaries and lagoons, whereas the Megalopa should avoid remaining in the cooler marine waters and initiate its migration towards shallow coastal lagoons.

The larval development of the spider crab Epialtus bituberculatus H. Milne Edwards which lives on rocky shores with algae such as Sargassum and Hypeneia, is described. Larvae were obtained from ovigerous females collected in Ubatuba, State of São Paulo, Brazil. Rearing was carried out at 24 ± 1°C, with an average salinity of 35%. Larval development consists of two zoeal stages and one megalopa. Zoeal development was completed in 9.5 days. Analysis indicated that zoeae of E. bituberculatus are very similar to those of E. brasiliensis Dana and Acanthonyx scutiformis (Dana). Differences noted between these species pertain to the setation of the carapace, maxillule and second maxilliped. The main morphological features useful for identification are presented together with a summary of features that characterize larvae of majid subfamilies in Brazil. A key for the identification of southwestern Atlantic majid zoeae to the family level is provided.

Metals are natural components in ecosystems; however, if these elements are in excess, they can have adverse effects on living organisms. This study analyzes the interference of copper, lead, iron and cadmium in acetylcholinesterase (AChE) and carboxylesterase (CbE) activities in zebrafish. AChE was significantly inhibited in vitro by copper, iron, lead and cadmium at higher concentrations (10 and 20 mmol/L), whereas CbE was inhibited only at a concentration of 20 mmol/L. In vivo, only lead and cadmium were able to cause AChE inhibition at higher concentrations, while iron didn't cause any changes, and copper promoted an increase in AChE activity at a concentration of 0.06 mg/L. CbE activity did not change at any of the times (two and seven days) and concentrations tested, except in the case of copper exposure, which resulted in a decrease in CbE activity. Indeed, iodoacetamide treatment didn't changed AChE neither CbE activities, results which indicate that the metal inhibiting effect is probably not due to its biding to thiol groups close the active site of the enzyme. This outcome reveals that metals are important esterase inhibitors in zebrafish, and should be considered in environmental monitoring studies that use esterase inhibition as exposure biomarkers of organophosphate and carbamate pesticides. © 2012 Elsevier Ltd.

This quali-quantitative study aimed to verify subjective exercise experiences of older women before and after exercise sessions in actual and virtual conditions, as well as, the preferred exercise condition. The sample was composed by 20 older women (71.1±6.5 years-old) who practiced dance sessions in actual and virtual conditions, and answered the Subjective Exercise Experiences Scale (SEES) before and after the activity. In virtual condition it was used the virtual game Just Dance I from the Nintendo Wii® console. In actual condition participants reproduced the same game movements, as demonstrated by the researcher. Wilcoxon and Mann-Whitney tests were used for data analyses (p<0.05). Significant decrease was observed in the psychological distress score of SEES after both conditions. Increase in positive well being score was found only in the virtual condition. Most of the older women chose the actual condition as the preferred.
