A Dança na Escola: um sério problema a ser resolvido

Pretendemos abordar os aspectos relacionados à Dança na Escola e pensarmos sobre uma formação continuada, a fim de discutir e refletir a elaboração de propostas de capacitação em Dança voltadas aos professores de Educação Física, principalmente no interior do Estado de São Paulo. Analisaremos a formação inicial dos professores, objetivos, conteúdos e possibilidades de aplicação da Dança no contexto educacional. Apesar do aumento das pesquisas em relação ao ensino da Dança na Escola, falta um espaço adequado e professores comprometidos com um trabalho sério, consciente e crítico, pois a hegemonia do esporte se encontra muito arraigada na cultura escolar. Uma forma de amenizar esse problema seriam cursos de capacitação, de forma permanente, voltados aos conteúdos de Dança, a fim de que esses professores possam ter vivências em práticas dançantes embasadas em uma fundamentação teórica para, assim, discutir, analisar e refletir a melhor maneira de trabalhar esta arte no âmbito escolar.

Feasibility of oncoplastic techniques in the surgical management of locally advanced breast cancer

Background: Locally advanced breast cancer (LABC) is still common in developing countries. The association between neoadjuvant chemotherapy (NC) and oncoplastic surgery (OS) might provide an oncological treatment with satisfactory aesthetic results.Purpose: The goal was to demonstrate if oncoplastic surgical techniques can be utilized to treat LABC which was submitted to neoadjuvant chemotherapy.Methods: This prospective clinical trial included breast cancer patients, clinical stage III, who underwent established NC regimen. All patients underwent preoperative planning to control the tumor size and to define the surgical technique. A detailed analysis of the pathological specimen was performed.Results: 50 patients were assessed and surgically treated. Tumor size ranged from 3.0 to 14.0 cm (median 6.5 cm). Pathologic response was rated as stable, progressive, partial response, and complete response in 10%, 8%, 80% and 2% of the cases, respectively. Seventeen (34%) patients were submitted to OS. No patient had positive margins. Skin involvement was presented in 36% of pathologic specimen.Conclusions: Oncoplastic surgical techniques for selected patients decrease the rates of radical surgery despite large tumors.

Isolation of coccidioides brasiliensis from armadillos (Dasypus noveminctus) captured in an endemic area of paracoccidioidomycosis

Paracoccidioides brasiliensis, the causative agent of paracoccidioidomycosis (PCM), was first isolated from armadillos from the Amazonian region where the mycosis is uncommon. In the present study, we report on the high incidence of PCM infection in armadillos from a hyperendemic region of the disease. Four nine-banded armadillos (Dasypus novemcinctus) were captured in the endemic area of Botucatu, São Paulo, Brazil, killed by manual cervical dislocation and autopsied under sterile conditions. Fragments of lung, spleen, liver, and mesenteric lymph nodes were processed for histology, cultured on Mycosel agar at 37 degrees C, and homogenized for inoculation into the testis and peritoneum of hamsters. The animals were killed from week 6 to week 20 postinoculation and fragments of liver, lung, spleen, testis, and lymph nodes were cultured on brain heart infusion agar at 37 degrees C. Paracoccidioides brasiliensis was isolated from three armadillos both by direct organ culture and from the liver, spleen, lung, and mesenteric lymph nodes of hamsters. In addition, one positive armadillo presented histologically proven PCM disease in a mesenteric lymph node. The three armadillos isolates (Pb-AL, Pb-A2, and Pb-A4) presented thermodependent dimorphism, urease activity, and casein assimilation, showed amplification of the gp43 gene, and were highly virulent in intratesticularly inoculated hamsters. The isolates expressed the gp43 glycoprotein, the immunodominant antigen of the fungus, and reacted with a pool of sera from PCM patients. Taken together, the present data confirm that armadillos an a natural reservoir of P. brasiliensis and demonstrate that the animal is a sylvan host to the fungus.

Desempenho zootécnico e percentual de consumo de alimento de rã-touro (Rana catesbeiana) na fase de recria (pós-metamorfose) do sistema anfigranja

Objetivou-se com este trabalho avaliar (em nível de campo) o desempenho zootécnico da rã-touro, Rana catesbeiana (Shaw, 1882), criada em ranários comerciais que utilizam o Sistema Anfigranja, e , simultaneamente, estimar os valores de consumo diário de alimento para compor uma tabela de referência para o arraçoamento dos animais. As avaliações demonstraram haver valores de produtividade com grandes variações, de acordo com a capacidade do produtor em assimilar a tecnologia e principalmente manejar os animais de forma padronizada, para atingir o ponto de equilíbrio no fluxo de produção de seu plantel. Os resultados encontrados nas unidades de observação monitoradas (aproximadamente 250 mil animais) atingiram os seguintes índices médios: a mortalidade (em %) 0,5 a 39,5 (média geral 12,0); o ganho de peso (g./dia) 0,4 a 2,5 (média geral 1,2); e a conversão alimentar 0,9 a 2,5 : 1,0 (média geral 1,4 : 1,0). É apresentada uma tabela com os percentuais estimados de consumo de alimento, em função do peso médio dos animais, para o cálculo da quantidade de ração a ser oferecida diariamente.

Salivary alpha amylase and cortisol levels in children with global developmental delay and their relation with the expectation of dental care and behavior during the intervention

The purpose of this study was to analyze the alpha-amylase (sAA) and cortisol levels in children with Global developmental delay (GDD) before and after dental treatment and its association with the children's behavior during treatment. The morning salivary cortisol levels and activity of sAA of 33 children with GDD were evaluated before and after dental treatment and were compared to 19 healthy children. The behavior of children with GDD during dental care was assessed by the Frankl scale. Children with GDD showed lower levels of sAA activity than healthy children, but this result was not significant. The salivary cortisol levels were similar between GOD and healthy children. GDD children showed increased levels of sAA (but not cortisol) prior to the dental treatment as compared to the post-treatment phase. GOD children who showed less favorable behavior during dental care had higher levels of sAA and salivary cortisol than GOD children with more favorable behavior, but only the sAA results were significant. In conclusion, GOD children show hyperactivity of the SNS-axis in anticipation of dental treatment which indicates the need for strategies to reduce their anxiety levels before and during dental care.

Fracture resistance of bleached teeth restored with different procedures

This study evaluated the fracture resistance of teeth submitted to internal bleaching and restored with different non-metallic post. Eighty mandibular incisors were endodontically treated and randomly divided in 10 groups (n = 8): G1- restored with composite resin (CR), G2- CR + fiber-reinforced composite post (FRC, Everstick post, Sticktech) cemented with resin cement self-etch adhesive (RCS, Panavia F 2.0, Kuraray), G3- CR + FRC + self-adhesive resin cement (SRC, Breeze, Pentral Clinical), G4- CR+ glass fiber post (GF, Exacto Post, Angelus) + RCS, G5- CR + GF + SRC. The G6 to G10 were bleached with hydrogen peroxide (HP) and restored with the same restorative procedures used for G1 to G5, respectively. After 7 days storage in artificial saliva, the specimens were submitted to the compressive strength test (N) at 0.5 mm/min cross-head speed and the failure pattern was identified as either reparable (failure showed until 2 mm below the cement-enamel junction) or irreparable (the failure showed <2 mm or more below the cement-enamel). Data were analyzed by ANOVA and Tukey test (α = 0.05). No significant difference (p < 0.05) was found among G1 to G10. The results suggest that intracoronal bleaching did not significantly weaken the teeth and the failure patterns were predominately reparable for all groups. The non-metallic posts in these teeth did not improve fracture resistance.

Placental Volumes Measured by 3-Dimensional Ultrasonography in Normal Pregnancies From 12 to 40 Weeks' Gestation

Objective. The purpose of this study was to construct nomograms of placental volumes according to gestational age and estimated fetal weight. Methods. From March to November 2007, placental volumes were prospectively measured by ultrasonography in 295 normal pregnancies from 12 to 40 weeks' gestation and correlated with gestational age and estimated fetal weight. Inclusion criteria were healthy women, singleton pregnancies with normal fetal morphologic characteristics on ultrasonography, and confirmed gestational age by first-trimester ultrasonography. Results. The mean placental volume ranged from 83 cm(3) at 12 weeks to 427.7 cm(3) at 40 weeks. Linear regression yielded the following formula for the expected placental volumes (ePV) according to gestational age (GA): ePV` (cm(3)) = -64.68 + 12.31 x GA (r = 0.572; P < .001). Placental volumes also varied according to estimated fetal weight (EFW), and the following mathematical equation was also obtained by linear regression: ePV = 94.19 + 0.09 x EFW (r = 0.505; P < 0.001). Conclusions. Nomograms of placental volumes according to gestational age and estimated fetal weight were constructed, generating reference values.

Métodos de produção de mudas, distribuição de matéria seca e produtividade de plantas beterraba

Comparou-se desenvolvimento de mudas de beterraba (cv. Tall Top Early Wonder), produzidas por diferentes métodos, através da distribuição de matéria seca na planta. Comparou-se os tratamentos T1 - mudas produzidas em bandejas de 288 células (1,2 x 10-5 m³); T2 - 200 células (1,6 x 10-5 m³) ; T3 - 128 células (3,2 x 10-5 m³); T4 - 128 células (7,2 x 10-5 m³); T5 - semeadura direta e T6 - mudas de raiz nua. Aos 28 dias após a semeadura (DAS), as mudas produzidas em bandejas foram transplantadas para campo, juntamente com mudas de raiz nua (T6). O delineamento experimental foi de blocos ao acaso com quatro repetições. Foram coletadas plantas semanalmente dos 28 aos 98 DAS. Determinou-se a matéria seca das folhas, pecíolos, raízes e da parte aérea e a matéria fresca das raízes. Aos 98 DAS, realizou-se a colheita das raízes comerciais, expressando-se a produtividade em kg ha-1. Para o tratamento T5, o espessamento da raiz tuberosa começou 42 DAS. Por sua vez, as plantas provenientes dos tratamentos T1, T2, T3, T4 e T6 iniciaram o acúmulo de matéria seca nas raízes a partir dos 56 DAS. Os métodos de produção de mudas não influenciaram significativamente na produtividade da cultura, porém aumentaram o ciclo, quando comparado à semeadura direta. Caso a disponibilidade de área seja fator limitante, a produção de mudas em bandejas é recomendável, sendo indicadas bandejas de 288 células.
