Throughout the history of medicine surgeons realized the importance of the patella to the functioning of the knee. The main function of the patella is to increase the mechanical efficiency of the quadriceps tendon and knee extensor mechanism. It was found that 50% to 80% of the fractures without deviation of the patella have the transversal pattern, possibly due to excessive tensile forces applied to the extensor mechanism. The purpose of this study is to analyze the loads to which a patella is submitted during a normal extension movement of knee. This analysis will be done by modeling a 3D patella and subsequent load simulation as, described in medical literature, using the finite element method

The equine locomotors system alterations are very frequent and corresponds a large portion of cases in equine medicine. The most equine veterinarian’s challenge is to do a precise diagnosis of lameness cause to perform a specific and proper treatment as early as possible. The navicular syndrome is considered responsible for one third of lameness causes and, although much studied, its etiology is still not fully understood. The most varied methods of diagnosis, such as x-ray, magnetic resonance, bursography, scintigraphy, computed tomography and ultrasound, have been used to assess podotrochlear apparatus situation in order to diagnose this syndrome. Among them transcuneal ultrasound can be used to observe some important structures such as the flexor surface of distal sesamoid bone, distal deep digital flexor tendon, distal sesamoid ligament entheses odd and the distal phalanx. The aim of this present paper is provide a brief review on the use and the technique of ultrasonography on third phalanx transcuneal region evaluation and its interpretation on navicular syndrome diagnosis in horses

O presente trabalho propõe discutir as produções literárias contemporâneas sobre a temática do vampirismo. Este estudo se fundamenta em análises de textos por meio da observação das práticas discursivas que os constituem. Tomando como corpus os romances Crepúsculo e Lua Nova de Stephenie Meyer, as observações partem dos pressupostos teóricos da Semiótica Discursiva e da Análise do Discurso, aos quais são incorporados estudos sobre cultura, sociologia e identidade. Parte-se do princípio de que o discurso é produto da cultura e, desse modo, incorporam-se a ele fatores históricos e sociais. Por essa razão, torna-se importante examinar os elementos dialógicos e intertextuais dos textos anteriormente apontados em relação às outras produções que tratam do mesmo tema e de outros possíveis, encontrados no corpus. Assim, busca-se compreender primordialmente os mecanismos fundamentais que tornam o texto um objeto de comunicação e de significação

Currently the company suffers a heavy influence of media, through their tentacles people are reached and clawed into a consumerist context, and the reason for the success of this market share is linked to aesthetics. An ideal beauty standard is followed, aimed at recognizing social, emotional success, professional and loving. Thus, people are accustomed from his childhood with the image of a perfect prince or princess, heroes that is becoming increasingly more muscular and developed throughout the evolution of cinema. While the aesthetic perfection is internalized by society and see that this beauty is not a particular good for some people, but everyone should become pretty standard to suit hence those who do not fit this stereotype are somehow excluded from the circle of society standard. One way people try to develop and hone the look is through weight training exercises in specialized academies. The problem is when it appears not the contentment of the individual in relation to his body. Even when your muscles are increasing, for the person who suffers from Vigorexia changes are significant to the point never to be content with their state of development, which is seen distorted and underestimated. Thus this paper aims to describe the situation and how the routine Vigorexia context and people are distorted to suit the aesthetic and social demands that are made, through a literature search on the muscle dysmorphia. It is of paramount importance to know the pathological picture of Vigorexia not only by professionals of Psychology, Psychiatry and Medicine, but also for Physical Educators that are constantly present in an active and that can positively or negatively influence the routine and pathological picture of these people with Muscular Dysmorphia

Considerando que a notícia impressa, televisual ou on-line não se restringe à elaboração do texto com aporte visual; de que, ao contrário, muitas vezes o projeto gráfico, o fotográfico e o videográfico, além da composição e estrutura de seus elementos, têm participação determinante na construção da notícia, este projeto parte da necessidade de um estudo crítico sobre a forma como a criança vem sendo representada (em imagens, sejam ilustrações ou fotografias) pelo jornalismo dirigido ao público adulto e geral. Diferentemente dos estudos no campo da Psicologia Social, do Direito ou da Comunicação com ênfase no agendamento social que dão destaque para temas de grande apelo social como violência, educação ou direito da criança e do adolescente, este estudo delimita seu objeto, abordagem e fundamentação na investigação da imagem e nas teorias da imagem e da mídia, abarcando, com isso, a variedade de temas que envolvem o universo infantil (desde os aspectos lúdicos e imaginativos até aqueles de maior dramaticidade e de grande apelo midiático). O objetivo deste projeto é demonstrar qual é a imagem (ou imagens) que a mídia brasileira contemporânea (jornais impressos e on-line) tem da criança (ou das crianças) e qual o comportamento dessa mídia no agendamento, pautagem e produção de tais imagens que representam as crianças em diversas situações. Para isso, serão analisadas as imagens de crianças apresentadas nos jornais Folha de S.Paulo, O Estado de S.Paulo, Jornal da Tarde, Jornal do Brasil e O Dia. Esses formam o corpus principal e dão enlevo para as imagens com produção em processo “mais imediato” – onde nota-se um tipo de jornalismo mais factual

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 ) ...

By the early 20th century, the blood vessels could only be seen by anatomical studies. Shortly after the discovery of X-rays by Conrad Roentgen in 1895, the first experiments with radiographic imaging were performed with blood vessels. In 1905, the first experiment involving catheterization of arterial and venous system in dogs was performed and only in 1914 performed on living human patients. Parallel to these landmarks, there were advances in diagnostic imaging devices and the evolution of contrast substances was of utmost importance to the current angiography occupy a prominent role not only in terms of diagnosis, but also in the treatment of various disorders. The main objective of this review is to weave historical considerations and comparisons between the different methodologies used in angiography, because its importance; that may be in future, a veterinary diagnostic decisive test

This study aims to determine surface skin doses in dogs (with suspected pulmonary metastasis) submitted to chest X-rays using the technique of thermoluminescence dosimetry. Twenty seven exams from different dogs were performed at the Faculdade de Medicina Veterinária e Zootecnia da Universidade Estadual Paulista (FMVZ-UNESP/Botucatu). The doses were evaluated using thermoluminescent dosimeters of calcium sulphate doped with dysprosium (CaSO4:Dy) produced by the Instituto de Pesquisas Energéticas e Nucleares (IPEN-CNEN). The pulmonary metastasis exams are carried out in three projections, one dorsal-ventral and two lateral-lateral. During the procedures the projection thicknesses and source-skin surface distances were registered. To simulate the dog phantom the dosimeters were positioned in a cubic simulator (30x30x30 cm) of polymethylmethacrylate (PMMA) filled with water and irradiated according to the parameters of projections with the X-ray energies ranging from 45 to 70 kV. To estimate the surface skin dose the dose-response curves were obtained for X-ray energies of 50 and 70 kV using the diagnostic X-ray beam machine of the Instruments Calibration Laboratory of IPEN for doses of 1.5, 2.0, 2.5, 3.5 and 4.0 mGy. The main difficulty of this work was the dog immobilization that is reflected in poor-quality diagnostic imaging and, consequently, demands the repetition of the exams, which contributes to the increase of the doses received by the animals being studied and the clinical staff. The doses evaluated in this type of procedure are between 0.43 and 4.22 mGy. This research has shown to be extremely important for the assessment of doses involved in veterinary diagnostic radiology procedures, and as a parameter in the individual monitoring of pet’s owners who assist the animal positioning and occupationally exposed workers of the Department of Veterinary Radiology
