Revista Brasileira de Saúde e Produ??o Animal , 2011,
Abstract: Objetivou-se com este trabalho avaliar o perfil lipídico e a composi o química dos filés de tilápia nilótica (Oreochromis niloticus) mantida em três condi es de cultivo, por um período de 120 dias. Foram utilizados 2075 machos sexados de tilápia, distribuídos em dois tanques de terra e um tanque de alvenaria. Os tratamentos aplicados foram: dieta base em tanque de alvenaria; dieta base em tanque de terra e alimenta o natural por meio de fertiliza o química e organica em tanque de terra. O delineamento experimental foi inteiramente casualizado, com três tratamentos e dez repeti es. Os parametros avaliados foram: identifica o do plancton, perfil de ácidos graxos e teores de umidade, proteína bruta, extrato etéreo e cinzas dos filés. Os dados obtidos foram submetidos à análise de variancia e as médias dos tratamentos foram comparadas pelo teste de Tukey (5% de significancia). Foram encontrados cinco gêneros distintos de zooplancton e quatro gêneros de fitoplancton predominantes. Os resultados demonstraram n o haver diferen a estatística para o teor de umidade e cinzas dos filés. Porém, os animais mantidos no sistema fertilizado apresentaram filés com maior teor de proteína bruta e menor teor lipídico, além de uma melhor rela o mega-3/ mega-6, com maiores quantidades de DHA (ácido graxo docosahexaenóico). This study aimed to evaluate the lipid profile and the chemical composition of the fillets of Nile tilapia (Oreochromis niloticus) maintained under three raising conditions, for a period of 120 days. A total of 2075 sexed males of tilapia were utilized, allotted into two ponds and one alvenaria pond. The applied treatments were: feeding with a basal diet in the alvenaria pond; feeding with the basal diet in the earthen pond and natural feeding through chemical and organic fertilization. The experimental design was in a completely randomized design, with three treatments and ten replicates. The evaluated parameters were: identification of plankton, profile of fatty acids and contents of moisture, crude protein, etereo extract and ashes of the fillets. The data were subjected to analysis of variance and the means of the treatments were evaluated by Tukey′s test (5% of significance). A total of five predominant distinct genera of zooplankton and four genera of phytoplankton were found. The results shown any statistical differences for the moisture and ashes contents of the fillets over all treatments tested. Therefore only the animals raised under the fertilization system shown increased crude protein content and decreased lipid content. The fatty aci

Educa??o em Revista , 2012, DOI: 10.1590/S0102-46982012000100009
Abstract: this article investigated the contribution that keeping a diary, made to pedagogy students who had already attended a course with a supervised teaching stage, in which one of the activities involved the development of field diaries. data was collected from questionnaires with open questions. data analysis showed that the students recorded the events in the diary shortly after the supervised lesson/teaching period and that they produced a detailed description of the facts/events. for most students, keeping a diary allowed them to reflect on the practice (of other students) they observed, and on their own practice, while also assisting their memory of events and permitting some detachment from their experiences, thereby allowing a more profound analysis of what took place. moreover, it provided evidence of the importance of the supervisor offering feedback, written or oral, and also the importance of referring to theoretical literature while reflecting on one's teaching.
Estado de Minas: do jornalismo literário à escrita técnica
Adriane Vidal Costa,Ewerton Martins Ribeiro
Conex?o : Comunica??o e Cultura , 2009,
Abstract: Neste artigo, analisa-se o processo pelo qual o jornalismo impresso diário praticado no jornal Estado de Minas se afastou gradativamente do discurso literário entre as décadas de 20 e 60 do século XX, mais especificamente, desde a funda o desse periódico, em 1928, até a instaura o do Golpe Militar em 1964. O estudo colabora para a compreens o do porquê e de como esse afastamento se deu: de forma n o linear, mas sempre crescente em uma macroanálise. Para a pesquisa, foram selecionados e analisados, em amostra, sob o aporte teórico da análise do discurso, oito exemplares do periódico, respeitando o recorte de tempo especificado.
The Effects of Different Titanium Surfaces on the Behaviour of Osteoblast-Like Cells  [PDF]
Fabiano Ribeiro Cirano, Adriane Yaeko Togashi, Márcia Martins Marques, Francisco Emílio Pustiglioni, Luiz Ant?nio Pugliesi Alves Lima
Journal of Biomedical Science and Engineering (JBiSE) , 2015, DOI: 10.4236/jbise.2015.86036
Abstract: This study investigated the influence of different titanium surfaces on the differentiation of rat osteoblast-like cells (osteo-1). Osteo-1 cells were cultured on the following titanium surfaces: 1) pretreated, smooth surface (PT); 2) sandblasted and acid etched surface (SLA); and 3) sandblasted and acid-etched surface rinsed under nitrogen protection to prevent exposure to air and preserved in isotonic saline solution (modSLA). Cell metabolism, total protein content, collagen content and alkaline phosphatase (AP) activity and the formation of calcified nodules were analyzed. The titanium surface did not influence cell metabolism, total protein content and collagen content. The SLA surface influenced cell differentiation, with the observation of a significant reduction of AP activity and formation of calcified nodules after 21 days compared to the PT surface. No difference was observed between the PT and modSLA surfaces. All titanium surfaces tested permitted the full expression of the osteoblast phenotype by osteo-1 cells, including matrix mineralization.

Abstract: We reviewed the case notes of 203 patients who were treated for sarcomas of the oral and maxillofacial region over a period of 5 years. There were 98 male cases (mean age 31.4 ± 12.8 years) and 105 female cases (mean age 29.3 ± 10.4). Kaposi’s sarcoma accounted for 82.8% cases, and rhabdomyosarcoma 6.9% followed by osteosarcoma and chondrosarcoma at 2.5% each. Except for Kaposi’s sarcoma, surgery in combination with radiotherapy and/or chemothe- rapy was the main stay of treatment. Survival data was not available for most of our patients.
