Abstract: Este estudo se prop e investigar o tipo de prática de ensino dos ‘mestres’ de caratê nas academias da Grande Vitória (ES). A metodologia adotada consistiu da coleta de dados por meio da observa o e da aplica o de entrevistas estruturadas. Os dados coletados evidenciaram que os conteúdos s o tratados de maneira dogmática; a metodologia é baseada na explica o oral e demonstra es do professor; a rela o professor-aluno favoreceu as decis es unilaterais do professor; na avalia o verifica-se a exatid o das técnicas ensinadas. Em síntese, pode-se concluir que a presen a dos valores da tradi o e do esporte nas aulas de caratê s o fatores impeditivos para ado o de práticas pedagógicas mais críticas e significativas. This research work aims at investigating teaching practices among karate instructors in the gyms of the greater Vitoria area (ES). The adopted methodology consists of data collection through observation, and structured interviewing. The collected data show that contents are treated in a dogmatic manner; methodology is based on oral explanations and teacher demonstrations; the teacher-student relationship favors one-sided decisions made by the teacher; examinations verify accuracy of techniques taught. In a summary, one can conclude that the presence of tradition and sports values in karate lessons is a blocking factor to the adoption of more critical and meaningful pedagogical practices. Keywords: karate – sport pedagogy – pedagogical practices. Este estudio propone investigar el tipo de práctica de ense anza de los “expert” en karate en las academias de Grande Vitória (ES). La metodología adoptada consistió en la recolección de datos por medio de la observación y de la aplicación de entrevistas estructuradas. Los datos reunidos evidencian que los contenidos son tratados de una manera dogmática; la metodología es basada en la explicación oral y las demostraciones del profesor; la relación profesor-alumno favorece las decisiones unilaterales del profesor, y, en la evaluación, se verifica la exactitud de las técnicas ense adas. En síntesis, se puede concluir que la presencia de los valores de la tradición y del deporte en las clases del karate es un factor que impide la adopción de prácticas pedagógicas más críticas y significativas. PALABRAS CLAVE: karate – pedagogía del deporte – práctica pedagógica.

Abstract: Plasma concentration of progesterone and 17β-estradiol of black-rumped agouti (Dasyprocta prymnolopha) during the estrous cycle. The agouti is a game animal that have been raised in captivity for conservation and sustainability purposes. However, the management of wild animals in an intensive breeding system requires an assertive knowledge of its reproductive parameters, one of the most important features for production improvement. Besides, little information is available regarding changes in reproductive hormone profiles in agouti. The objective of this study was to evaluate the hormonal profile of progesterone and 17β-estradiol during the estrous cycle of the agouti (Dasyprocta prymnolopha). The hormones were analyzed by radioimmunoassay. Blood samples were collected without sedation twice a week. The concentrations of progesterone were as follows: proestrus 0.78+0.39ng/ml, estrus 2.83+2.34ng/ml, metestrus 1.49+1.24ng/ml, diestrus 3.71+1.48ng/ml. In the estrous phase, an increase in the progesterone level was observed during a period of 24h. The average 17 β-estradiol levels were as follows: proestrus 2 030.98+961.00pg/ml, estrus 1 910.56+650.54pg/ml, metestrus 1 724.83+767.28pg/ml, diestrus 1 939.94+725.29pg/ml. The current results suggest that the progesterone plasma concentration during the estrous cycle in the agouti has a similar increasing, stabilizing and decreasing pattern, as in domestic mammals. Agoutis have two phases of follicular development, as two periods of 17β-estradiol peaks were observed, the first one in the metestrus and the second during the proestrus. Spontaneous ovulation seems to occur after the progesterone peak, possibly indicating that this hormone is associated with the ovulatory process. A more detailed investigation is needed for better understanding of how progesterone influences ovulation. Studies on the involvement of progesterone in follicular rupture can be carried out, using steroid biosynthesis inhibitors and observing the effect of this hormone on ovarian activity of proteolytic enzymes in the follicular wall. Rev. Biol. Trop. 59 (1): 29-35. Epub 2011 March 01. El conocimiento de los procesos reproductivos de especies de importancia económica local son indispensables para apoyar su producción en cautiverio y garantizar su manejo sostenible. El objetivo del presente trabajo fue evaluar los niveles hormonales de progesterona y 17β-estradiol durante el ciclo estral en agutí (Dasyprocta prymnolopha). La recolección de sangre se realizó dos veces por semana, sin sedación. Las hormonas fueron analizadas por radioinmuno

Abstract: fanconi?s anemia is a rare autosomal recessive disorder characterized by congenital malformation, bone marrow failure and genomic instability, with a predisposition to develop malignancies, especially the leukemias and upper aerodigestive tract tumors. due to inherent characteristics to this syndrome, the treatment of such neoplasms is particularly difficult. in this paper we report the case of a 24-year-old woman with fanconi?s anemia who developed a squamous cell carcinoma of the hypopharynx; she had none of the traditional risk factors, such as smoking and alcohol abuse. we also briefly review the literature about this topic

Abstract: the objective of this research was to analyze female agouti puberty. we did not observe the onset of puberty when the females were raised without males. when an adult male was put together with other adults and no cycling females, the onset of estrous cycle was observed after 10 to 60 days. when the young females were raised with a male, the onset of puberty was reached at 9 months. we concluded that the male agouti influences the onset of puberty in females, and that the dominant female, apparently, inhibits or delays the puberty of the other agouti females of the group. we suggest further studies be made concerning the social control of the reproduction of these animal.

Abstract: purpose: to assess the influence of central and peripheral corneal thickness on the iop measurement by tonopen. methods: the iop of 58 eyes from suspected and glaucomatous patients was evaluated by goldmann′s tonometry (gt) and, by tonopen xl on the central (tc) and peripheral (tp) regions of the cornea. using the dgh 5100e pachymeter, we also measured the corneal thickness in its central (cct) and peripheral (at 6:00 h) regions (pct). patients with any corneal changes were excluded. the mean values of all measurements was comparatively analyzed (gt x tc; gt x tp; tc x tp; cct x pct) by the paired t test and by regression and correlation analysis. results: the means (± standard deviation) of iop obtained with gt, tc and tp were respectively 14.6 (±3.3) mmhg; 18.9 (±2.9) mmhg and 20.7 (±3.7) mmhg with a statistical highly significant difference (p<0.001). the means (±standard deviation) of central and peripheral corneal thickness were respectively 526 (±42.3) and 639 (±52.9) μm, also with a statistical highly significant difference (p<0.001). the correlation coefficients (r) between the measurements were 0.71 (p<0.001) for gt and tc; 0.65 (p<0.001) for gt and tp and 0.64 (p<0.001) for tc and tp. conclusions: there was a positive correlation between the measurements performed with tonopen xl and goldmann′s tonometer at the central region of the cornea and the mean iop was higher with tonopen xl. the mean iop obtained by tp was higher than that obtained by tc. these data showed that tonopen xl, besides providing higher iop readings than those with goldmann′s tonometer, is influenced by the corneal thickness presenting higher iop readings in the periphery than in the central region of the cornea.

Abstract: OBJETIVO: Avaliar a influência da espessura corneana central e periférica na medida da press o intra-ocular (Po) obtida com o Tonopen XL. MéTODOS: Avaliou-se a Po de 58 olhos de pacientes suspeitos ou portadores de glaucoma cr nico simples com o ton metro de aplana o de Goldmann e com o Tonopen XL na regi o central (Tonopen Central) e na periferia corneana (Tonopen Periférico), além da espessura corneana (paquímetro DGH 5100e), também na regi o central (Paquimetria Central) e na periferia da córnea (Paquimetria Periférica). Compararam-se estatisticamente os grupos Goldmann com Tonopen Central, Goldmann com Tonopen Periférico, Tonopen Central com Tonopen Periférico e Paquimetria Central com Paquimetria Periférica. RESULTADOS: A Po média (? desvio-padr o) em mmHg com o Goldmann foi de 14,6 (?3,3), com o Tonopen Central de 18,9 (?2,9) e com o Tonopen na periferia da córnea de 20,7 (?3,7), tendo sido encontrada diferen a altamente significativa (p<0,0001). A média (? desvio-padr o) da Paquimetria Central em micra foi de 526 (?42,3) e da Paquimetria Periférica foi de 639 (?52,9), sendo esta diferen a altamente significativa (p<0,001). Houve correla o positiva entre as medidas da Po pelo Goldmann e Tonopen Central (r=0,71, p<0,001) e entre as medidas pelo Goldmann e Tonopen Periférico (r=0,65, p<0,0001) e Tonopen Central e Tonopen Periférico (r=0,64, p<0,0001). CONCLUS ES: Houve correla o positiva entre as medidas com o Tonopen XL e o Goldmann, mas a Po média pelo Tonopen foi maior que aquela obtida pelo Goldmann. A Po média pelo Tonopen Periférico foi maior que a pelo Tonopen Central. O Tonopen, além de fornecer valores de Po maiores que o Goldmann, é influenciado pela espessura corneana apresentando valores de Po mais elevados na periferia da córnea que na regi o central.
