Patterns of energy allocation to reproduction in three Amazonian fish species
Santos, Rodrigo N. dos;Amadio, Sidinéia;Ferreira, Efrem J. G.;
Neotropical Ichthyology , 2010, DOI: 10.1590/S1679-62252010005000001
Abstract: the study considered the influence of the hydrological cycle and gonadal development on the accumulation and use of energy in three fish species from an amazonian flooded area. fishes were sampled over a 24 hour period at monthly intervals between july 2004 and june 2005 using gillnets of different mesh sizes. body cavity fat and gonadosomatic indices were determined, as well as energy content of gonads and muscles. amongst the studied species, different means of energy allocation for reproduction were found: acestrorhynchus falcirostris allocate energy from body cavity fat to its gonads; pygocentrus nattereri uses mainly energy accumulated in the muscles for the process of gonadal maturation; and hoplosternum littorale uses energy accumulated in their muscles and body cavity fat for reproductive processes. it is quite clear that the flood pulse regulates the gain and use of the energy reserves in fishes from the amazonian floodplain.

Abstract: El retiro de hueso de sínfisis mandibular ha sido utilizado ampliamente para diferentes procedimientos reconstructivos maxilofaciales. El objetivo de esta investigación fue establecer la existencia de la reparación ósea en el defecto creado en sínfisis debido al retiro de hueso. Treinta pacientes (22 mujeres, 8 hombres) de entre 21 y 65 a os fueron operados para retirar hueso de mentón que fue posteriormente aplicado en reconstrucción ósea alveolar; las cirugías fueron realizadas por dos cirujanos maxilofaciales y los pacientes fueron evaluados con telerradiografías en la etapa preoperatoria, postoperatoria inmediata (PIn) y postoperatoria tardía (PTar), donde se realizaron medidas horizontales y verticales del defecto óseo; los valores fueron estudiados con la prueba t de Student con valor de p<0,05. Luego del retiro óseo se observó un defecto vertical promedio de 12,80±1,99 y horizontal de 8,33±1,77; luego de un a o, se obtuvo una disminución de 32,8% en el sentido vertical y 50,3% horizontal, presentando significancia estadística en relación al PIn. Se concluye que existe reparación ósea del defecto originado en sínfisis siendo próximo al 30%-50% en la evaluación de un a o posterior a la cirugía. Bone harvest of mandibular symphysis has been used in maxillofacial reconstruction procedures. The aim of this research was to establish the presence of bone repair into osseous defect caused by removal of bone. Thirty patient s, 2 female and 8 male, ranging between 21 and 65 years of age underwent surgery for chin bone harvest and alveolar reconstruction. The surgery was performed by two maxillofacial surgeons and the patients were evaluated with lateral radiography in the pre-operatory stage, in early post-operatory and in late post-operatory stages. Horizontal and vertical measures of bone defect were realized; the dates were analyzed by Student t test with a value of p<0.05. After bone harvest, a vertical defect of 12.80 ±1.99 was observed and a horizontal defect of 8.33 ± 1.77 was observed. After one year the defect decreased to 32.8% in vertical evaluation, and 50.3% in the horizontal evaluation with a statistical significance (p<0.05) in relation to the early post-operatory stage. Therefore, we conclude that in bone repair of mandibular symphysis defect is close to 30 - 50% in a one-year follow-up.

Abstract: Determinou-se as melhores épocas de aplica o e dosagens do BTH e seu efeito no controle do cancro da haste isoladamente ou em combina o com fungicidas. Foram testadas duas doses de BTH (2,5 e 5,0 g/100L) aplicadas aos 11; 18; 22 e 24 dias após transplantio das mudas. Utilizou-se o delineamento inteiramente casualizado, no esquema fatorial 2 x 4 (doses x épocas) com oito repeti es. Posteriormente, utilizou-se a melhor época e dose de BTH associada aos fungicidas: difenoconazole (30 mL de p.c./100L), azoxystrobin (16 mL de p.c./100L) alternado com chlorothalonil (250 g de p.c./100L) e chlorothalonil (250 g de p.c./100L). Utilizou-se também BTH isoladamente e benomyl (70 g de p.c./100L) sem a adi o de BTH. As aplica es foram realizadas em intervalos de sete dias até os 28 dias após o transplantio. Os seis tratamentos foram distribuídos inteiramente ao acaso em 15 repeti es. Avaliou-se a severidade da doen a por meio de escala de notas. Os resultados encontrados demonstraram que a associa o de difenoconazole + BTH foi mais eficiente no controle do cancro da haste em mel o rendilhado.

O presente estudo considerou a influência do ciclo hidrológico e matura o gonadal no acúmulo e utiliza o da energia em três espécies de peixes, numa área de planície de inunda o amaz nica. As amostras foram obtidas mensalmente durante o período de julho de 2004 a junho de 2005, utilizando redes de emalhar com vários tamanhos de malhas, durante 24 horas. O índice de gordura cavitária, índice gonadossomático, e teor energético dos músculos e g nadas foram analisados. Dentre as espécies analisadas, foram detectados diferentes padr es de aloca o de energia: Acestrorhynchus falcirostris aloca energia das reservas de gordura cavitária para as g nadas; Pygocentrus nattereri utiliza energia dos músculos para este fim e Hoplosternum littorale, além da gordura cavitária, utiliza também energia acumulada nos músculos para realiza o dos processos reprodutivos. Ficou evidente que o pulso de inunda o exerce forte influência no acúmulo e utiliza o das reservas energéticas dos peixes da planície de inunda o amaz nica.

Abstract: Neste estudo buscou-se fazer uma análise do conhecimento e do uso de métodos anticoncepcionais (MAC) entre mulheres de 10 a 49 anos residentes na Regi o Sul do Município de S o Paulo, no ano de 1992. Foram estudadas 1.157 mulheres em idade reprodutiva, tendo em vista variáveis que pudessem caracterizá-las quanto ao conhecimento de métodos anticoncepcionais (MAC), ao seu uso e ao motivo pelo qual optaram por determinado método. Verificou-se que 86% das mulheres desse universo referiram conhecer algum MAC, sendo a pílula o mais citado (95,3%) e, em segundo lugar, o condom masculino, que obteve 92,6% das respostas. Dentre as mulheres, 14% relataram n o conhecer nenhum MAC. Das mulheres pesquisadas, 66,4% têm vida sexual e, dessas, 65,1 % fazem uso de algum tipo de MAC. A pílula é usada por 35,3% das usuárias de MAC, enquanto que 42,9% est o esterilizadas. Quanto ao uso do condom masculino, apenas 5,2% referem o uso. Apesar do alto índice de conhecimento de MAC - sobretudo, a pílula e o condom masculino - constatou-se baixo uso dos mesmos associado à alta freqüência de mulheres esterilizadas, ficando a anticoncep o circunscrita à pílula e à esteriliza o feminina.

Abstract: brazil must comply with international quality standards and animal welfare requirements in order to maintain its position as world's largest exporter of poultry meat. with the scenario of global climate change there is the forecast of occurrence of extreme events with characteristics of both excess cold and heat for several regions of the country. this study aimed to evaluate the effectiveness of using images of infrared thermography to evaluate the loss of sensible heat in young broilers fed different dietary energy levels. twenty birds were reared in a house with appropriate brooding using infrared lamps. birds were distributed in a completely randomized experimental into two treatments: t1 (control diet with 2950 kcal me/kg-1), and t2 (high-energy diet with 3950 kcal me/kg-1). infrared thermographic images of the birds were recorded for four consecutive days. one bird was randomly chosen per treatment, and had special images taken and analyzed. average surface temperature of the body area was calculated using the surface temperature recorded at 100 spots (50 at the front and 50 at the lateral side of the bird's body). mean surface temperature of the flock was calculated recording 100 spots on the group of birds. total radiant heat loss was calculated based on the average data of surface temperature. the results indicated that the young broilers fed the high-energy diet presented a metabolic energy loss equivalent to 0.64 kcal h-1, while the birds fed with the control diet lost 2.18 kcal h-1. this finding confirms that oil supplementation to the diet reduces bird heat loss. the infrared camera was able to record young broilers' surface temperature variation when birds were fed diets with different energy contents.

RGO : Revista Gaúcha de Odontologia , 2008,
Abstract: Odontomas are the most common types of odontogenic tumors, as they are considered more as a developmental anomaly (hamartoma) than as a true neoplasia. The aim of the present study is to describe a clinical case of compound odontoma, analyzing its most commonsigns, its region of location, the decade of life and patient’s gender, disorders that may occur as well as the treatment proposed. In order to attain this objective, the method was description of the present clinical case and bibliographic revision, arriving at the result that the treatment for this type of lesion invariably is surgical removal (enucleation and curettage) and the prognosis is excellent. The surgical result was followed up in the post-operative period by radiographic exam, and it was possible to conclude that there was complete cicatrization and tissue repair.
