Digestibilidade aparente da matéria seca, matéria orgânica e energia bruta e nutrientes digestíveis totais de uma ração completa para bovinos de diferentes grupos genéticos

Avaliou-se a digestibilidade da matéria seca (DMS), matéria orgânica (DMO) e energia bruta (DEB) e os nutrientes digestíveis totais (NDT) de uma ração completa, composta por 44,3% de feno de capim-braquiaria, 55% de concentrado e 0,7% de mistura mineral, fornecida a bovinos de diferentes grupos genéticos (Gir, Nelore, Guzerá, Santa Gertrudis e Caracu), pelas metodologias de coleta total de fezes e com indicador interno (lignina em detergente ácido -- LDA), em delineamento inteiramente casualizado, com três repetições por grupo genético, com análise de variância individual dentro de cada metodologia e uma análise de correlação entre as metodologias. As correlações foram médias ( 0,47 a 0,51) e significativas (P<0,0602; P<0,0697; P<0,0747; P<0,0522), respectivamente, para DMS, DMO, DEB e para NDT. A recuperação do indicador (95,06%) foi semelhante entre os grupos genéticos. Não houve diferença entre grupos genéticos para DMS, DMO, DEB e nos valores de NDT pelas metodologias de coleita total de fezes e com LDA, com médias de 53,31 e 50,33; 55,16 e 52,25; 52,22 e 49,20; e 53,39 e 50,61%, respectivamente. Assim, a LDA foi eficiente na estimativa da digestibilidade, em função de sua adequada recuperação. Os nutrientes foram utilizados de forma semelhante pelos grupos genéticos.

Effect of Glycolic Extract of Dillenia indica L. Combined With Microcurrent Stimulation on Experimental Lesions in Wistar Rats

This study evaluated the wound healing activity of a glycolic extract of Dillenia indica (GED) prepared from the mature fruits of the plant applied alone or in combination with microcurrent stimulation to skin wounds surgically induced on the back of Wistar rats. Methods. The animals were randomly divided into six groups: (A) negative control group; (B) group receiving microcurrent application (MC; [10 mu A/2 mins]); (C) group treated with GED; (D) group treated with an emulsion containing GED; (E) group treated with GED and MC, and (F) group treated with the emulsion containing GED and MC. Tissue samples were obtained 2, 6, and 10 days after injury and underwent structural and morphometric analysis, Results. There were observed differences in wound healing among the various treatments when compared to the control group. The combination of microcurrent plus extract or microcurrent plus emulsion containing GED was advantageous in all of the studied parameters (P < 0.05) when compared to the other groups with positive effects seen regarding newly formed tissue, number of fibroblasts, and number of newly formed blood vessels. The morphometric data confirmed the structural findings. Conclusion. Microcurrent application alone or combined with GED exerted significant effects on wound healing in this experimental model. This was probably due to the efficacy of microcurrent application since the extract alone did not significantly accelerate the healing process. D indica fruit extract most likely participates in the wound healing process as a result of its anti-inflammatory properties.

Dilatacao pneumatica no megaesofago avancado. Resultados do sequimento tardio

Six patients with advanced Chagas' megaesophagus with poor condition for surgical indication due to severe malnutrition and concomitant diseases were submitted to pneumatic dilatation with the aid of the endoscope. The method consists in leading the tip of the pneumatic dilatator into the cardia with the tip of the endoscope. Insufflation of the balloon must be slow and progressive with visualization of the mucosa of the cardia after insufflating of 2 pounds of air pressure. An excellent symptomatic relief was seen in the five-year follow-up but without improvement in the degree of the esophageal dilatation.

Esofagopatia chagásica complicada com esôfago de Barrett

Gastroesophageal reflux disease (GERD) is an uncommon condition in chagasic esophagopathy not previously treated. In this report, a case of chagasic esophagopathy associated to GERD and complicated with Barrett's esophagus is described. Potential pathophysiologic mechanisms underlying the condition are presented and commented.

Associação entre o achado de cárdia incompetente à endoscopia digestiva alta e presença de esofagite de refluxo

Incompetent cardia (IC) or loose cardia is not uncommon at endoscopic examination but its meaning is not clear. Such incompetence could facilitate gastroesophageal reflux and the appearance of esophagitis as a consequence. The aim of this study is to investigate if there is an association between IC and reflux esophagitis (RE). A review was made of 395 consecutive endoscopic reports of adult males and females performed at the Botucatu Clinics Hospital, of the Unesp - University of the State of São Paulo. Diagnosis of IC is defined by the endoscopic image in which the cardia is partially opened and/or involves the endoscope in a loose manner. Esophagitis characterization was based in the Los Angeles classification. The statistical analysis showed a significant association between CI and RE (p < 0.0001). Although there is not a clear explanation for this association, some hypotheses could be suggested involving hypotonic LES, diaphragmatic crura ineffectiveness and TLESR disorders as conditions able not only to keep the cardia relaxed but also to the reflux followed by esophagitis.

Adenocarcinoma de apêndice: Relato de dois casos e revisão da literatura

Background: The adenocarcinoma of the appendix is a rare disease, generally identified as an acute appendicitis in the clinical presentation. Preoperative diagnosis is extremely difficult and uncommon. Objective: To present two cases of adenocarcinoma of the appendix, unique for presenting in early ages, and a complete literature review on this topic. Cases report: First case: a 24-year-old man submitted to appendectomy for acute inflammatory abdomen. Sent to hospital due to a histopathological diagnosis of mucinous adenocarcinoma of the appendix. Right hemicolectomy, epiploectomy, ganglion and partial abdominal wall resection were performed. The patient is now in chemotherapy. Second case: a 32-year-old man presented, during appendectomy, with vegetant lesion on the apex of the appendix. The histopathological study revealed the presence of adenocarcinoma of the appendix. Right hemicolectomy with ganglion resection was performed. The patient does not present signs of recurring disease. Conclusion: The macroscopic and clinical similarity between adenocarcinoma of the appendix and acute appendicitis makes it important to check out histopathological study results. The cases above reinforce this requirement, as the authors have found adenocarcinoma of the appendix in young patients.

Úlcera de cameron como causa incomum de anemia por deficiência de ferro

Cameron ulcers are chronic linear lesions willing on the mucosal folds, the level of diaphragmatic impression, in patients with hiatal hernia. Its clinical relevance is due to the potential risk of gastrointestinal complications, such as acute or chronic bleeding and anemia. Usually, the diagnosis is incidental by upper gastrointestinal endoscopy. Proton pump inhibitors are essential for the conduct of cases and the administration of iron when the anemia is associated. Already, the benefit of surgery is in refractory cases. We present a case of this entity of a 50-year-old patient in postmenopausal who developed anemia due to iron deficiency and normal initial endoscopy.

O trabalho associado como princípio educativo e a educação escolar: notas a partir das fábricas recuperadas brasileiras e argentinas

This article aims to discuss the school education and other forms of education at Recovered Factories (RFs) in Latin America, especially in Brazil and Argentina. To achieve our goal, we made a brief assessment of the current historical moment, and then we try to differentiate the anti-capital struggles from the punctual struggles. In the third and fourth sections, we observed RF’s positive aspects (Associated Labor as an educational principle) and the negative ones: the cooptation by the State or the degeneration at the capitalist market. The projects of professional education in RFs, the demands of school contents and form flagged by FRs were exposed in the fifth section.

Desenhos sobre aprendizagem e não aprendizagem: a construção do conhecimento social sob o enfoque piagetiano

The article presents preliminary data of a survey that aimed to investigate the beliefs of children and adolescents about not learning. A total of 80 students, aged 6 to 16 years participated of the study. Among the participants, 20 are 6 years old, 20 are 9, 20 are 12 and 20 are 16 years old. As methodological tool, it was asked the participants to draw a person that learns and another one that doesn’t learn. Data was analyzed according to the Piagetian perspective for the construction of social knowledge. The main results indicate that a significant part of the participants tend to blame the students for the result of no learning. This indicates that students are able to consider the amplitude of different dimensions of social phenomena only partially. When considering the level of understanding of social reality, it was observed that, even at older ages, participants have a very basic notion of the social world.

Repensando o lugar da representação, da transmissão e da experiência no ensino da Filosofia

The question that we develop in this study can be proposed as follows: can knowledge be transmitted in a representational way through an explanation in such a way that the one who is learning does not have an experience itself of what he is learning? Grounded on Hume, Deleuze, Rancière and Gallo, we aim to show that only the experience with the object can promote effective learning, for violating the thought to search by itself for its meaning and for its own understanding, and not for the mere repetition of contents that have been shared and taken as important, as we have seen in schools.

Das virtualidades do cuidado da infância em Rousseau ao seu pleno governo na arte pedagógica

This article discusses the genesis and development of the relationship between art education and childhood. To address this issue, we highlight the virtualities of the care with childhood postulated by Rousseau and Kant, also in its genesis, as opposed to an extreme government or to the domain that has on it or from it, in its subsequent development in contemporary times. Discussed, in this way, how these virtues have been abandoned by the practices included by art pedagogical, in order to find a place for thought of Rousseau and think it in its actuality.

Educação e lutas sociais no Brasil pós-ditadura: da democratização à ausência de alternativas

Analisam-se os fundamentos do processo de democratização da sociedade brasileira e seus impactos no campo da educação. Pressupõe-se que: a) democracia não é um conjunto dado de valores; b) as sociedades capitalistas são estruturalmente desiguais, incompatíveis com qualquer noção substantiva de igualdade; c) o Estado não é o lócus da realização do interesse geral; d) os conflitos de classes formam o terreno histórico no qual se objetivam as possibilidades democráticas. Com base nisso, afirma-se que tanto nas relações sociais em geral, como na educação, efetivou-se um processo de democratização no Brasil pósDitadura, fruto dos conflitos sociais que encaminharam a sociedade brasileira a conquistas favoráveis às classes trabalhadoras. Processo este que foi contraditório: de um lado, estavam as forças populares, para as quais democratização implicava conquista de direitos e participação nos processos decisórios; de outro lado, as forças que desejavam preservar a ordem vigente, ainda que tivessem de acatar mudanças na sua configuração (de Ditadura para um regime de direito). Nas conclusões argumentamos que, com a chamada redemocratização, houve certa abertura para uma democracia mais substantiva, capaz de dar vazão aos conflitos sociais. Abertura que logo se reverteu com o neoliberalismo, o que vem levando a um contexto de crescente ausência de alternativas.
