Estudo anatomorfológico, radiográfico e tomográfico de Schistosomus reflexus em ovino da raça Dorper: relato de caso

Schistosomus reflexus (SR) is a rare and fatal congenital anomaly, primarily observed in ruminants, presenting fetus with dorsiflexion of the vertebral column, exposure of thoracic and visceral organs, and scoliosis. A caesarian was performed on a Dorper sheep on a farm in Botucatu-SP and according to the general characteristics and findings observed in the necropsy of the fetus it was an SR case. The radiography indicated a marked ventro-dorsal deviation of the thoracolumbar column segment and deformity of the ribs. On the computed tomography the integrity of the bones and organs were detected, except for the absence of a lumbar vertebra. No data were available in the literature for SR diagnosis in sheep by image, so radiographic and tomographic exams of the fetus were done.

Efeitos da parede de levedura em dieta úmida na microbiota fecal, na produção de gás e na morfologia intestinal de gatos adultos

The aim of this study is to evaluate the effects of yeast extract (EPL) in the moist diet on the fecal microbiotal, gas production and intestinal morphology of adult cats. Twenty adult cats from both sexes were randomly assigned to four treatments: 1) moist commercial diet (control); 2) control + 0,2% yeast extract dry matter; 3) control + 0,4%; and 4) control + 0,6%. Fecal microbiology and intestinal morphology were performed by radiographic, ultrasound, colonoscopy and intestinal biopsy exams for histology. There were no significant differences (P>0,05) for lactic acid bacteria counts and clostridium-reductor, gas area in the bowel (radiographic), wall thickness of the colon (ultrasound) and colonocytes count/globet cells (histology). Through colonoscopy, changes in characteristics of the intestinal mucosa in animals receiving treatment 4 were noticed. It is concluded that the addition of up to 0.6% EPL had no effect on the parameters evaluated, but further studies are needed to understand the action mechanisms and additive effects for domestic cats.

Metodologia de avaliação e análise de termografia em equinos

A análise termográfica é uma tecnologia proveniente da engenharia e utilizada na Segunda Guerra Mundial para detecção de forças armadas inimigas. Foi aplicada inicialmente na medicina para avaliação de articulações com artrites e hoje apresenta importante função no diagnóstico de câncer de mama em mulheres. Na medicina veterinária, há mais de trinta anos é técnica de diagnóstico auxiliar na clínica de equinos, para avaliação de processos inflamatórios tais como tendinites, desmites, artrites, miosites ou ainda no diagnóstico de fraturas, lesões na coluna ou em nervos periféricos. Por ser uma técnica com alta sensibilidade, exige que seu operador tenha treinamento e doutrinamento, não só para a execução dos exames, mas também para a análise de seus resultados. Diante disso, muitos pesquisadores afirmaram que os exames termográficos de aplicabilidade científica deveriam ser realizados em local com temperatura controlada, em torno de 23oC. Ao se trabalhar com equinos, torna-se difícil encontrar ambientes amplos o suficiente e com controle de temperatura para que os exames sejam feitos, o que praticamente inviabilizaria o uso da termografia na pesquisa com cavalos. Assim, este trabalho propôs um método de padronização das temperaturas que permite realizar termografias de extremidades de membros em ambientes variando entre 18 e 35oC. O método proposto, nomeado como PadTemp, foi validado em cavalos saudáveis e aplicado em experimentos de verificação de eficácia de fármacos e de acompanhamento de cirurgias ortopédicas.

Análise da densidade óssea de rádio-ulna de cães SRD utilizando o método de imersão

Imaging diagnosis is a medical specialty that uses imaging techniques to perform diagnosis. In diagnostic imaging various methods are used such as direct absorption of photons - SPA and DPA, radiographic photometry, the dual-energy radiographic absorptiometry - DEXA, ultrasound, magnetic resonance imaging, computed tomography and optical densitometry in radiographic image. The dog can be considered one of the most widely used animals in the study of bone diseases and searching for a reliable diagnosis, although not an ideal model for the study of osteoporosis, because these animals tend not to develop a decrease in bone mineral density. The objective of this study was to analyze bone density in mongrel dogs from the determination of the variation of density along the radio-ulna bone and also the mean value related to gender, weight and age of individuals. The density analysis carried out showed that for this data set, there is a significant difference in the case of gender and age of the animal and may generalize according to these variables. The only significant difference was found in the weight, which increases bone mass is related to weight gain through the growth of the animal

Estudo da contribuição do espalhamento nuclear não elástico na trajetória mais provável de prótons em alvo homogêneo composto de água

The Therapy with proton beam has shown more e ective than Radiotherapy for oncology treatment. However, to its planning use photon beam Computing Tomography that not considers the fundamentals di erences the interaction with the matter between X-rays and Protons. Nowadays, there is a great e ort to develop Tomography with proton beam. In this way it is necessary to know the most likely trajectory of proton beam to image reconstruction. In this work was realized calculus of the most likely trajectory of proton beam in homogeneous target compound with water that was considered the inelastic nuclear interaction. Other calculus was the analytical calculation of lateral de ection of proton beam. In the calculation were utilized programs that use Monte Carlo Method: SRIM 2006 (Stopping and Range of Ions in Matter ), MCNPX (Monte Carlo N-Particle eXtended) v2.50. And to analytical calculation was employed the software Wolfram Mathematica v7.0. We obtained how di erent nuclear reaction models modify the trajectory of proton beam and the comparative between analytical and Monte Carlo method

Análise quantitativa dos parâmetros físicos e radiométricos de procedimetnos radioterapicos em tumores de mama

The paper presents the radiometric parameters determined by the medical physicist during routine radiotherapy planning service in cases of breast cancer . The contours of the breast volume in patients undergoing radiation breast tumors at the Hospital das Clinicas, Faculty of Medicine , UNESP, Botucatu ( HCFMB ) during the year 2012 were analyzed . In order to analyze the influence of physical and radiometric parameters for the determination of the dose distribution of irradiated breast volume , four measurements of isodose curves were prepared in four different heights breast , and compared with the isodose curves plotted computationally . In the routine of planning , the medical physicist must determine the isodose curve that gives the best dose distribution homogeneity in the irradiated volume . The choice of the treatment plan can be done by dedicated computer systems , which require significantly costly investments available services having better financial support . In the Service of Medical Physics , Department of Radiotherapy , HC FMB , we use a two-dimensional software for determination of isodose curves , however , this software is out of date and frequently becomes inoperable due to the lack of maintenance and it is a closed system without feasibility of interference from computer professionals . This fact requires manual preparation of isodose curves , which are subject to uncertainties due to the subjectivity in the clinical interpretation of medical radiation oncologist and medical physicist responsible for planning , plus dispendiar significant calculation time . The choice of the optimal isodose curve depends on the energy of the radiation beam , the geometry and dimensions of the irradiated area . The contours of the breast studied in this work evaluations showed that , for a given energy input , such as the energy of 1.25 MeV of gamma radiation Unit Telecobaltoterapia , the determination of the percentage depth dose ( PDP ) ...
