Aim: the purpose of this study is to present a case of surgically assisted rapid maxillary expansion using piezosurgery and describe the benefits of using this device in this type of procedure. Case description: patient had adento-skeletal deformity Cl III with asevereatresia of jaw and underwent a rapid maxillary expansion and surgically assisted with the use of piezosurgery. Conclusion: the piezosurgerycan be used as an alternative in oral and maxillofacial surgery wich features provide greater accuracy and safety in surgery.

O extraordinário desenvolvimento da produção avícola, particularmente no setor de frango de corte, tornou o Brasil um importante produtor e exportador de carne de frango. Esse fato aliado a proibição da utilização de cama de frango como ração para ruminantes pela Instrução Normativa nº15 de 17 de julho de 2001, fez com que este resíduo se tornasse um problema ecológico e de saúde pública de alta relevância, tanto pelo volume de resíduos gerado, quanto pela composição do mesmo, que pode conter diversos fármacos utilizados neste tipo de manejo, além de uréia, que após a oxidação natural no ambiente, resulta em nitrato que tem alto poder de contaminação de mananciais hídricos, principalmente subterrâneos. Dentre as substâncias que podem estar presentes na cama de frango, estão os antimicrobianos, utilizados como promotores de crescimento das aves. No Brasil, são pouquíssimos os trabalhos dedicados a investigar a ocorrência e o impacto ambiental de antimicrobianos. Desta maneira, este trabalho teve como objetivo otimizar e validar método para análise de três fluoroquinolonas (ciprofloxacina, norfloxacina e enrofloxacina) em cama de frango. O método estudado baseou-se em trabalhos da literatura em que moléculas similares foram analisadas em diversas matrizes, compreendendo a extração em ultrassom com acetonitrila acidificada com ácido acético (3% v/v) e análise por CLAE-FLU, modo isocrático com a fase móvel composta por 0,02 M H3PO4:ACN (83:17, v/v). Foram avaliados os parâmetros cromatográficos quanto à resolução, eficiência, linearidade e limites de detecção e quantif-1 para os três analitos. O tempo de análise do método cromatográfico otimizado é de 7,5 minutos. Avaliou-se também o efeito de matriz que foi significativo para norfloxacina e ciprofloxacina, correspondendo a 16 e 20%, respectivamente. Para a enrofloxacina a amostra...

The objective of this study was to investigate the influence of lineage of oocytes donors on the number and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore breed cows derived from two lineages of bulls (Karvadi; K and Taj-Mahal; T). Both maternal (Km and Tm) and paternal (Kp and Tp) lineages, as well as their combinations were investigated. Oocyte aspirations were repeatedly performed with an aspiration interval of 15 days in 56 donor females. Recovered cumulus oocyte-complexes (COCs) were counted, morphologically examined and classified into seven categories (grades from I to VII) according to the number of layers of the cumulus oocyte and cytoplasm appearance. The mean number of oocytes retrieved from donors of lineage Tp-Tm was significantly higher (28.23±1.92, P<0.05) than those obtained from lineages Kp-Tm, Kp-Km, and Tp-Km (21.34±1.32, 21.28±1.73, and 16.72±1.31, respectively). There was no significant difference in the mean number of recovered oocytes between donors of lineages Kp-Km and Kp-Tm, whereas animals of lineage Tp-Km yielded the lowest number of oocytes. Higher mean number of grade III oocytes was recovered from donors of lineage Kp than lineage Tp (10.11±0.66 versus 8.79±0.58, respectively), with more grade III oocytes being obtained in both lineages as compared to the others. Paternal lineage did not influence the quality of recovered oocytes in any other category, but both Kp and Tp yielded a great mean number of oocytes graded as I, II, and III (3.14±0.21; 4.93±0.33, and 10.11±0.66 versus 3.19±0.21, 5.59±0.44, and 8.79±0.58, respectively) than those classified as IV, V, VI, and VII. However, when considering the data from the maternal lineage significantly more oocytes (P<0.05) of grade I, II and III were obtained from Taj-Mahal (11.67 ± 0.67, 5.9±0.42 and 3.64±0.25, respectively) than for lineage Karvadi, with similar results for oocytes of grades IV, V, VI, and VII. Similarly to the paternal lineage, the number of oocytes of grade III was superior (P<0.05) when compared to other categories for both lineages. In conclusion, we demonstrate here a direct influence of lineage of oocyte donor on the production and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore cows.

Radiography is usually the primary method of diagnosis to be used in the initial evaluation of the chest. In view of recent technological advances in ultrasound machines, noncardiac transthoracic ultrasound has become an important method of diagnosis for diseases of the lung, pleura, mediastinum and chest wall. Despite limitations due to the difficulty of efficient sound propagation in air, this exam allows fast decisions and makes sample collection safer and more effective. Knowledge of the sonographic chest anatomy is however restricted because of the artifact caused by the presence of air in lungs. When absent, it facilitates the detection of thoracic alterations. The aim of this review is to present the main abnormalities that are likely to be detected by ultrasonography.
