This work aimed to evaluate the carcass yields, commercial cuts and non-carcass components of Santa Inês lambs fed with 30, 40, 50 or 60% of oldman saltbush hay with concentrated. Were used 32 castrated lambs at 8 months old and initial body weight of 22 + 1.97kg, housed individually and slaughtered after 60 days of feedlot. The weights of hot and cold carcass decreased linearly with the inclusion of saltbush hay in the diet, however, there was no effect for true carcass yield and commercial cuts: shoulder (19.26%), neck (8.52%) ribs (26.57%) and leg (33.88%). There was a linear decrease for ribeye area and fat thickness when the level of hay in the diet increased. The weights and yields of skin, liver, heart, kidneys with perirenal fat, omental and mesenteric fats decreased linearly with the inclusion of hay in the diet, while the content (%) of gastrointestinal tract increased. The increased proportion of saltbush hay in the diet of lambs provided adequate true carcass yield and commercial cuts, however, reduces the ribeye area and fat thickness, important measurements in the qualitative evaluation of the lamb's carcass.

Ultrasound is considered the method of choice for evaluation of the gastrintestinal wall. Thickening of the wall is the most common ultrasonographic finding in gastric disorders. Inflammatory and neoplastic disorders are the most frequent causes of wall thickening. Case report 1: Boxer, with abdominal distension, ultrasound examination detected marked diffuse thickening of the gastric wall with loss of definition of wall layers. Fine needle aspiration guided by ultrasound diagnosed gastric carcinoma. Case report 2: mixed breed dog presenting oliguria, emesis and melena, the ultrasound examination showed diffuse thickening of the gastric wall, but with preserved layers and presence of calcification areas. An inflammatory process of the gastric wall was diagnosed using cytology. The distinction between inflammatory and neoplastic processes is performed based on several factors such as distribution, symmetry, size and architecture of the parietal layer in the lesions, and ultrasonography is a valuable tool to direct diagnosis and treatment.

A novel AC Biosusceptometry (ACB) system with thirteen sensors it was implemented and characterized in vitro using magnetic phantoms. The system presenting coils in a coaxial arrangement with one pair of excitation coil outside and thirteen pairs of detection coils inside. A first-order gradiometric configuration was utilized for optimal detection of magnetic signals. Several physical parameters such as baseline, number of turns, excitation field and diameters were studied for improvement of the signal/noise ratio. This system exhibits an enhanced sensitivity and spatial resolution, due to the higher density of sensors/area. In the future those characteristics will turn possible to obtain images of magnetic marker or tracer in the gastrointestinal tract focusing on physiological and pharmaceutical studies. ACB emerged due to its interesting nature, noninvasiveness and low cost to investigate gastrointestinal parameters and this system can contribute for more accurate interpretation of biomedical signals and images

The global growing demand for food coupled with the direction of eating habits for products of animal origin, become even more necessary the search for alternatives to increase production. In this way, improve animal performance through the use of ionophores has become an effective measure to increase production and profitability of farms. Among the ionophores, monensin is the best known so far, as to their effect on the pattern of rumen fermentation and its consequences on animal production, especially by improving the quality or quantity of nutrients available for absorption through the gastrointestinal tract and consequently the performance of ruminants

O gênero Astronium, pertencente à família Anacardiaceae, é composto por cerca de 35 espécies, sendo típico das regiões norte e nordeste do Brasil. De acordo com a literatura, apenas a espécie Astronium urundeuva foi investigada sob o ponto de vista farmacológico, sendo detectada atividades antiulcerogênica , antiinflamatória e efeitos no trânsito gastrintestinal . Nas espécies A. graveolens e A. fraxinifolium foram avaliados somente os óleos essenciais, sendo que em A. graveolens um desses compostos voláteis mostrou atividade repelente a insetos. Desta forma, percebe-se que a investigação desse importante gênero vegetal ainda é incipiente. Estudos preliminares com o extrato em acetato de etila das folhas de A. graveolens mostraram grande concentração de compostos fenólicos, como derivados de ácido gálico e flavonoides, os quais estão descritos na literatura em geral como substâncias antioxidantes em potencial. As propriedades antioxidantes de diversas substâncias são alvo de interesse nos dias de hoje principalmente por estarem relacionadas à terapêutica de doenças degenerativas. Com o objetivo de dar continuidade aos estudos das espécies citadas, foram utilizadas neste trabalho técnicas de cromatografia como análise por cromatografia líquida de alta eficiência para o estudo do perfil químico de Astronium graveolens, separação e identificação de metabólitos secundários. Baseado na literatura e na comparação com padrões, os espectros de ultravioleta observados, indicaram que os extratos em acetato de etila da espécie em estudo são compostos por substâncias derivadas do ácido gálico, derivadas do ácido cafeoilquínico e também por flavonóides. A substância Ag1 foi identificada a partir de experimentos de comparação por CLAE usando banco de padrões, após verificação de similaridade entre tempo de retenção e máximo de absorção...

The Biosusceptometry AC (BAC) is a research tool that has been extensively explored by the group Biomagnetism IBB-UNESP for monitoring of the gastrointestinal tract, its response to a known drug or in vivo performance of solid dosage forms. During this period the BAC, which has the characteristics of high sensitivity and low cost, has been developed primarily for recording signals contraction of activity and traffic human gastrointestinal tract. With the possibility of producing images with this instrumentation, it was possible to evaluate different situations in vitro and in vivo for physiological studies and pharmaceuticals. Considering the good performance of this system to produce planar images, the first aim of the BAC system tomography (TBAC) was to evaluate the system performance of BAC to produce tomographic images of phantoms ferromagnetic for a single channel system. All these applications were only possible because of their sensitivity to materials of high magnetic suscepitibility as ferrite, which allow to produce an electrical signal proportional to the variation of the magnetic flux generated by the presence of magnetic marker next to a first-order gradiometer. Measuring this variation at various points was possible to generate planar images that recently came to be produced in systems with multiple detectors, said multi-channels. From planar images, also producing tomographic images of simulators BAC bars in a system of 13 channels using only the center channel, with good results when applied to simple objects as one and two bars. When testing the resolution of the system with more elaborate forms the quality and resolution of images reconstructed is not satisfactory, which would be solved by increasing the spatial sampling rate and hence the acquisition time. The present system works with an acquisition time of about five hours. Whereas this system will be applied for in vivo experiments, the acquisition time became a ...
