Paris, Wagner;Marchesan, Renato;Cecato, Ulysses;Martin, Thomas Newton;Ziech, Magnos Fernando;Borges, Gisele Daiane Silveira;
Acta Scientiarum. Animal Sciences , 2012, DOI: 10.4025/actascianimsci.v34i2.11507
Abstract: the work was carried out to assess mass production and nutritional content of winter forages using lopsided oat (avena strigosa) and white oat (avena sativa) intercropped with ryegrass (lolium multiflorum) and vetch (vicia sativa l.). the species were intercropped as the following treatments: lopsided oat with ryegrass (lo+rg); white oat with ryegrass (co+rg); lopsided oat with vetch (lo+v); white oat with vetch (co+v); lopsided oat, vetch and ryegrass (lo+rg+v); and white oat, ryegrass and vetch (co+rg+v). the study evaluated total forage mass production of each intercropping and crude protein levels, neutral detergent fiber and in vitro digestibility coefficient of dry matter. the results indicate that forage yield of oats was higher in early assessments, and ryegrass and vetch were higher in the final evaluation period. the crude protein levels and neutral detergent fiber were higher at the start of the experiment for all evaluated treatments, and those including vetch intercropped with oats showed an increase in these parameters in the final period due to the presence of vetch, which has a more delayed cycle.

Abstract: The present work to evaluate the effect of supplementation of urea release slow partial substitution of urea present in the common protein salt of heifers grazin Tifton-85 during the winter. The study was coducted in the period from May to September 2010. In an area of ??11.6 hectares of grazing Tifton-85 (Cynodon dactylon), divided into four paddocks of 2.9 acres, 36 heifers were kept testers ( Red Angus Nellore), treated as follows: Only mineralized salt (SM) protein salt with urea (SP); protein salt with 25% substitution of urea by slow degradation of urea (SPLD25) and protein salt with 50% substitution of urea by slow degradation of urea (SPLD50). There was no effect of different sources of supplementation on animal performance (P>0.05). However, differences were observed between the experimental periods, in consequence of the variation in chemical and structural composition of the forage. O presente trabalho objetivou avaliar o efeito da suplementa o com uréia de libera o lenta em substitui o parcial da uréia comum, presente no sal proteinado de novilhas pastejando em capim Tifton-85 no período do inverno. O trabalho foi realizado no período de maio a setembro de 2010, em uma área de 11,6 hectares de pastagem de Tifton-85 (Cynodon dactylon), dividida em quatro piquetes de 2,9 hectares. Foram mantidas 36 novilhas testers ( Red Angus Nelore), submetidas aos seguintes tratamentos: apenas sal mineralizado (SM); sal proteinado com uréia (SP); sal proteinado com 25% de substitui o da uréia por uréia de lenta degrada o (SPLD25); e sal proteinado com 50% de substitui o da uréia por uréia de lenta degrada o (SPLD50). N o houve efeito das diferentes fontes de suplementa o sobre o desempenho dos animais (P > 0,05), sendo recomendado a utiliza o de sal mineralizado que apresenta menor custo.

Es?fago de Barrett e displasia: critérios diagnósticos
Rodrigues, Maria Aparecida Marchesan;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2004, DOI: 10.1590/S1676-24442004000300009
Abstract: this review focuses on conceptual aspects of barrett's esophagus and barrett's related dysplasia and highlights current diagnostic problems on the interpretation of these lesions. barrett's esophagus results from longstanding gastroesophageal reflux. endoscopically it is recognized by the presence of glandular mucosa in the tubular esophagus above the esophagogastric junction at variable lenghts. histologically it is characterized by the presence of specialized columnar epithelium with globet cells expressed as intestinal metaplasia. the importance of barret's esophagus is the risk for developing adenocarcinoma. dysplasia is the main biomarker for the progression to adenocarcinoma. the pathologic diagnosis of barrett's esophagus should contain information on the presence and grade of dysplasia. distinguishing betweeen dysplasia and regenerative changes in the face of active inflammation may be difficult. correct interpretation and grading of dysplasia is an important goal for pathologists, since it is a major factor on follow-up and treatment of the patients.
Phenolic compounds and antioxidant activity of rice
Walter, Melissa;Marchesan, Enio;
Brazilian Archives of Biology and Technology , 2011, DOI: 10.1590/S1516-89132011000200020
Abstract: the aim of this work was to study the phenolic compounds identified in rice, their antioxidant activity and their potential beneficial effects on health. in vitro and in vivo studies evaluating the rice grains with different pericarp colour (light brown, red and black) showed potential beneficial effects on health related to the polyphenol content of the grain, such as reduction of oxidative stress, aid in the prevention of cancer, cardiovascular diseases and complications of diabetes, among others.

Abstract: purpose: to present a lingual frenum protocol with scores. methods: from a specific evaluation of the lingual frenum used until 2004, it was designed a new protocol with specific clinical history and evaluation. ten experienced speech language pathologists in orofacial myology area used the protocol for 3 years in different population, and from their consideration, the protocol was re-structured and received scores. the absence of alteration was considered zero and the ones that were found were punctuated in ascending order. from the final version, 4 speech language pathologists, with specialization in orofacial myology at least for 8 years, were trained by the researcher to apply the protocol. the protocol was applied in 2008 and 2009 in 239 persons: 160 children between 7 years and 2 months old and 11 years and 7 months old; and in 79 adults from 16 years and 8 months on. results: in the protocol with scores, when the sum of anatomical tests is equal or bigger than 3, the frenum can be considered altered. when the sum of functional tests is equal or bigger than 25, the interference of the lingual frenum in the oral functions can be considered. conclusion: the lingual frenum protocol with score seemed to be efficient to differentiating altered and normal lingual frenum.

Brazilian university technology transfer to rural areas

Abstract: in agriculture, there is a difference between average yield obtained by farmers and crop potential. there is technology available to increase yields, but not all farmers have access to it and/or use this information. this clearly characterizes an extension and technology transference problem. there are several technology transfer systems, but there is no system to fit all conditions. therefore, it is necessary to create extension solutions according to local conditions. another rural extension challenge is efficiency, despite continuous funding reductions. one proposal that has resulted from extension reform worldwide has suggested integration between the public and private sectors. the public universities could play the role of training and updating technical assistance of human resources, which is the one of the main aspects that has limited technology transfer. the objective of this study was to identify approaches to promote technology transfer generated in brazilian public universities to rural areas through literature review. an experimental approach of technology transfer is presented here where a brazilian university extension vice-chancellor incorporates professionals from consolidated research groups according to demand. in this way, public universities take part of their social functions, by integrating teaching, research, and extension.
