To isolate, to concentrate and to purify bacteriophages from isolates of P. aeruginosa; To observe the capacity of bacteriophages to infect isolates of P. aeruginosa susceptible and multiresitant to antimicrobial; To caractherize bacteriphages by electronic microscopy techniques. 10 isolates of Pseudomonas aeruginosa from LEMC culture collection were submitted to the experiments of ideal temperature for the lyse region appearance in the MaConkey culture plate and 2 extraction methods for the concentration of the phages, clorophorm (Silankorva) and filtration plus centrifugation (Bergan). Three infected clinical isolates of multiresistant P. aeruginosa an one susceptible isolate ( PA01) were evaluated by 3 transmission electron microscopy techniques to caractherize phages morphologically (“on grid”, “on drop” and direct extraction from the lyse region of the culture plate). The ideal temperature to obtain lyses region was 37°C. The stock solutions, obtained through the methodologies of Sillankorva and Bergan, had satisfactory results in infecting the multiresistant isolate and the negative control. Among the 3 techniques of electronic microscopy tested the direct from the lyse plate was the best to obtain the micrography of the phages

Introduction: Adult patients are more prone to periodontal disease mainly caused by poor plaque control. In these patients, orthodontic movement is not contraindicated, but it is necessary to evaluate their periodontal status so that we can establish the appropriate treatment plan. Objective: The objective of this article is to describe and discuss the clinical cases of severely periodontally compromised individuals in need of oral rehabilitation. Methods: The study consisted of orthodontic treatment of two cases with periodontal involvement. After clinical and radiographic examinations, the cases were analyzed by a multidisciplinary team of Orthodontics, Periodontics and Prosthodontics, in order to provide the patient with the best possible esthetic, functional and stability outcomes. Periodontal treatment consisted of supra and subgingival scaling prior to orthodontic treatment, and regular maintenance performed on a quarterly basis throughout orthodontic movement. Activation was carried out every 45 to 50 days, with light forces. Retention remains to the present day, even after completion of the rehabilitation. Conclusion: Multidisciplinary oral rehabilitation treatment yields satisfactory results. The interaction between Orthodontics and Periodontics reveals that patients with reduced, but healthy periodontium, can receive orthodontic treatment as long as the forces applied do not exceed patient's biological limits.

Objective: To evaluate serum concentrations of CA-125 and soluble CD-23 and to correlate them with clinical symptoms, localization and stage of pelvic endometriosis and histological classification of the disease. Methods: Blood samples were collected from 44 women with endometriosis and 58 without endometriosis, during the first three days (1st sample) and during the 7th, 8th and 9th day (2nd sample) of the menstrual cycle. Measurements of CA-125 and soluble CD-23 were performed by ELISA. Mann-Whitney U test was used for age, pain evaluations (visual analog scale) and biomarkers concentrations. Results: Serum levels Of CA-125 were higher in endometriosis patients when compared to the control group during both periods of the menstrual cycle evaluated in the study. This marker was also elevated in women with chronic pelvic pain, deep dyspareunia (2nd sample), dysmenorrhea (both samples) and painful defecation during the menstrual flow (2nd sample). CA-125 concentration was higher in advanced stages of the disease in both samples and also in women with ovarian endometrioma. Concerning CD-23, no statistically significant differences were observed between groups. Conclusion: The concentrations of CA-125 were higher in patients with endometriosis than in patients without the disease. No significantly differences were observed for soluble CD-23 levels between groups.

La nanotecnología es el estudio que la mayoría de veces es tomada como una meta tecnológica que nos ayuda en el área de investigación para tratar con la manipulación y el control en forma precisa de la materia con dimensiones comprendidas entre 1 y 100 nanómetros. Recordando que el prefijo nano proviene del griego vavoc que significa enano y corresponde a un factor de 10^-9, que aplicada a las unidades de longitud corresponde a una mil millonésima parte de un metro. Ahora sabemos que esta ciencia permite trabajar con estructuras moleculares y sus átomos, obteniendo materiales que exhiben fenómenos físicos, químicos y biológicos, muy distintos a los que manifiestan los materiales usados con una longitud mayor. Por ejemplo en medicina, los compuestos manométricos y los materiales nano estructurados muchas veces ofrecen una mayor eficacia con respecto a las formulaciones químicas tradicionales, ya que muchas veces llegan a combinar los antiguos compuestos con estos nuevos para crear nuevas terapias e inclusive han llegado a reemplazarlos, revelando así nuevas propiedades diagnósticas y terapéuticas. A su vez, la complejidad de la información a nivel nano es mucho mayor que en los niveles biológicos convencionales y, por tanto, cualquier flujo de trabajo en nano medicina requiere, de forma inherente, estrategias de gestión de información avanzadas. Muchos investigadores en la nanotecnología están buscando la manera de obtener información acerca de estos materiales nanométricos, para mejorar sus estudios que muchas veces lleva a probar estos métodos o crear nuevos compuestos para ayudar a la medicina actual, contra las enfermedades más poderosas como el cáncer. Pero en estos días es muy difícil encontrar una herramienta que les brinde la información específica que buscan en los miles de ensayos clínicos que se suben diariamente en la web. Actualmente, la informática biomédica trata de proporcionar el marco de trabajo que permita lidiar con estos retos de la información a nivel nano, en este contexto, la nueva área de la nano informática pretende detectar y establecer los vínculos existentes entre la medicina, la nanotecnología y la informática, fomentando así la aplicación de métodos computacionales para resolver las cuestiones y problemas que surgen con la información en la amplia intersección entre la biomedicina y la nanotecnología. Otro caso en la actualidad es que muchos investigadores de biomedicina desean saber y comparar la información dentro de los ensayos clínicos que contiene temas de nanotecnología en las diferentes paginas en la web por todo el mundo, obteniendo en si ensayos clínicos que se han creado en Norte América, y ensayos clínicos que se han creado en Europa, y saber si en este tiempo este campo realmente está siendo explotado en los dos continentes. El problema es que no se ha creado una herramienta que estime un valor aproximado para saber los porcentajes del total de ensayos clínicos que se han creado en estas páginas web. En esta tesis de fin de máster, el autor utiliza un mejorado pre-procesamiento de texto y un algoritmo que fue determinado como el mejor procesamiento de texto en una tesis doctoral, que incluyo algunas pruebas con muchos de estos para obtener una estimación cercana que ayudaba a diferenciar cuando un ensayo clínico contiene información sobre nanotecnología y cuando no. En otras palabras aplicar un análisis de la literatura científica y de los registros de ensayos clínicos disponibles en los dos continentes para extraer información relevante sobre experimentos y resultados en nano medicina (patrones textuales, vocabulario en común, descriptores de experimentos, parámetros de caracterización, etc.), seguido el mecanismo de procesamiento para estructurar y analizar dicha información automáticamente. Este análisis concluye con la estimación antes mencionada necesaria para comparar la cantidad de estudios sobre nanotecnología en estos dos continentes. Obviamente usamos un modelo de datos de referencia (gold standard) —un conjunto de datos de entrenamiento anotados manualmente—, y el conjunto de datos para el test es toda la base de datos de estos registros de ensayos clínicos, permitiendo distinguir automáticamente los estudios centrados en nano drogas, nano dispositivos y nano métodos de aquellos enfocados a testear productos farmacéuticos tradicionales.---ABSTRACT---Nanotechnology is the scientific study that usually is seen as a technological goal that helps us in the investigation field to deal with the manipulation and precise control of the matter with dimensions that range from 1 to 100 nanometers. Remembering that the prefix nano comes from the Greek word νᾶνος, meaning dwarf and denotes a factor of 10^-9, that applyied the longitude units is equal to a billionth of a meter. Now we know that this science allows us to work with molecular structures and their atoms, obtaining material that exhibit physical, chemical and biological phenomena very different to those manifesting in materials with a bigger longitude. As an example in medicine, the nanometric compounds and the materials in nano structures are often offered with more effectiveness regarding to the traditional chemical formulas. This is due to the fact that many occasions combining these old compounds with the new ones, creates new therapies and even replaced them, reveling new diagnostic and therapeutic properties. Even though the complexity of the information at nano level is greater than that in conventional biologic level and, thus, any work flow in nano medicine requires, in an inherent way, advance information management strategies. Many researchers in nanotechnology are looking for a way to obtain information about these nanometric materials to improve their studies that leads in many occasions to prove these methods or to create a new compound that helps modern medicine against powerful diseases, such as cancer. But in these days it is difficult to find a tool that searches and provides a specific information in the thousands of clinic essays that are uploaded daily on the web. Currently, the bio medic informatics tries to provide the work frame that will allow to deal with these information challenge in nano level. In this context, the new area of nano informatics pretends to detect and establish the existing links between medicine, nanotechnology and informatics, encouraging the usage of computational methods to resolve questions and problems that surge with the wide information intersection that is between biomedicine and nanotechnology. Another present case, is that many biomedicine researchers want to know and be able to compare the information inside those clinic essays that contains subjects of nanotechnology on the different webpages across the world, obtaining the clinic essays that has been done in North America and the essays done in Europe, and thus knowing if in this time, this field is really being exploited in both continents. In this master thesis, the author will use an enhanced text pre-processor with an algorithm that was defined as the best text processor in a doctoral thesis, that included many of these tests to obtain a close estimation that helps to differentiate when a clinic essay contains information about nanotechnology and when it does not. In other words, applying an analysis to the scientific literature and clinic essay available in both continents, in order to extract relevant information about experiments and the results in nano-medicine (textual patterns, common vocabulary, experiments descriptors, characterization parameters, etc.), followed by the mechanism process to structure and analyze said information automatically. This analysis concludes with the estimation, mentioned before, needed to compare the quantity of studies about nanotechnology in these two continents. Obviously we use a data reference model (Gold standard) – a set of training data manually annotated –, and the set of data for the test conforms the entire database of these clinic essay registers, allowing to distinguish automatically the studies centered on nano drugs, nano devices and nano methods of those focus on testing traditional pharmaceutical products.

Introdução - Na prevenção primária das doenças cardiovasculares, a adoção de estilo de vida saudável representa uma das estratégias mais importantes. Entretanto, baixos índices de adesão e o abandono da dieta constituem obstáculo importante ao tratamento. Neste sentido, as intervenções cirúrgicas surgiram como um mecanismo promotor da restrição alimentar e têm ganhado importância não só pelo tratamento da obesidade como também no controle dos fatores de risco cardiovascular e na possível redução da mortalidade. Através de estudos clínicos foi possível observar que estas estratégias cirúrgicas promovem profundas modificações estruturais no trato gastrointestinal gerando aumento da saciedade e da sensibilidade à insulina. Em especial para os pacientes diabéticos, por si só associados a maior risco cardiovascular, as cirurgias bariátricas seriam capazes de promover um efeito muito intenso e agudo sobre os marcadores relacionados ao desenvolvimento da aterosclerose. Um evento muito definido no tempo como uma intervenção cirúrgica pode ser muito útil para o estudo e identificação de mecanismos que ainda não estão completamente estabelecidos no processo aterosclerótico. Objetivos - Analisar o comportamento das variáveis laboratoriais, clínicas e estruturais relacionadas ao desenvolvimento e progressão da aterosclerose em indivíduos diabéticos submetidos à cirurgia bariátrica. Métodos - Foram incluídos vinte voluntários diabéticos refratários ao tratamento clínico e que apresentavam obesidade abdominal. Deste grupo, metade foi aleatoriamente selecionada para realização da cirurgia bariátrica e metade foi mantida em tratamento clínico otimizado. Todos os participantes foram submetidos a exames clínicos e bioquímicos nas mesmas ocasiões, até trinta dias antes da cirurgia, três e vinte e quatro meses após a cirurgia. Nestas ocasiões além do perfil lipídico e da glicemia, determinamos os hormônios incretínicos, adipocinas. A avaliação da quantidade de gordura epicárdica e a presença de esteatose hepática será realizada somente após dois anos de seguimento em conjunto com as demais variáveis,. Foram incluídos também 10 indivíduos saudáveis e com IMC dentro da normalidade, como parte do grupo controle. Estes indivíduos foram submetidos à coleta de sangue em dois momentos para avaliação dos mesmos metabólitos. Resultados - No momento pré-intervenção os indivíduos do grupo cirúrgico e clinico eram diferentes em relação ao IMC, Glicemia e Triglicérides, sendo assim, os resultados obtidos foram ajustados minimizando o impacto destas diferenças. Após o seguimento de 3 meses, o grupo cirúrgico apresentou redução significativa nos valores de peso, IMC (33,4 ± 2,6 vs. 27,4±2,8 kg/m2, p < 0,001), HbA1c (9,26 ± 2,12 vs. 6,18±0,63%, p < 0,001), CT (182,9 ± 45,4 vs. 139,8 ± 13 mg/dl, p < 0,001), HDL (33,1 ± 7,7 vs. 38,4 ± 10,6 mg/dL, p < 0,001), TG (369,5 ± 324,6 vs. 130,8 ± 43,1 mg/dL, p < 0,001), Pro-insulina (12.72±9,11 vs. 1,76±1,14 pM, p < 0,001), RBP-4 (9,85±2,53 vs. 7,3±1,35 ng/ml, p < 0,001) e CCK (84,8±33,2 vs. 79,9 ± 31,1, ng/ml, p < 0,001), houve também aumento significativo nos níveis de HDL-colesterol (33,1 ± 7,7 vs. 38,4 ± 10,6 mg/dL, p < 0,001), Glucagon (7,4 ± 7,9 vs. 10,2±9,7 pg/ml, p < 0,001) e FGF- 19 (74,1 ± 45,8 vs. 237,3 ± 234 pg/ml, p=0,001). Um dado interessante foi que os valores de Pro-insulina, RBP-4, HbA1c e HDL- colesterol no grupo cirúrgico atingiram valores similares àqueles do grupo controle três meses após a intervenção, sendo que o FGF-19 apresentava valor duas vezes maior do que o encontrado no grupo de indivíduos saudáveis (237 ± 234 vs. 98 ± 102,1 pg/ml). O grupo clínico não apresentou variação nas variáveis clinicas, apenas nos valores de glucagon com redução significativa no período pós-intervenção (18,1 ± 20,7 vs. 16,8 ± 18,4 pg/ml, p < 0,001). Conclusão - Concluímos que indivíduos diabéticos descompensados e refratários ao tratamento clínico, quando submetidos à cirurgia bariátrica, apresentam uma alteração profunda do ponto de vista clínico, metabólico e hormonal, em relação ao indivíduos de mesmo perfil mantidos em tratamento clínico otimizado. Esta importante alteração, observada já com três meses após a intervenção, pode representar uma importante redução do risco cardiovascular nestes indivíduos. Individualmente, a notável modificação dos valores de FGF-19 associadas à intervenção devem ser estudadas com maior profundidade para compreensão de seu significado e sua potencial utilidade como marcador ou como um dos protagonistas no mecanismo de prevenção cardiovascular

Objective: analyze the effect of Kinesio Taping (KT) on the indirect clinical markers of muscle damage induced by eccentric exercises in the elbow flexors in healthy individuals. Materials and methods: It is a randomized controlled trial involving sixty volunteers at age group between 18 and 28 years randomly selected. The sample into three groups with twenty participants: control group (CG) – eccentric protocol without KT, KT group – eccentric with tensioned KT, placebo group – eccentric protocol KT with no tension. The evaluations took place at four moments; the first one was the basis line (AV1), after the second protocol (AV2) and the following two groups 24 (AV3) and 48 hours (AV4) after the intervention protocol. The muscle damage was induced by sixteen maximum eccentric contractions of the elbow flexors from the non-dominant limb, divided in two sets of eight repetitions, at 60º/s, with two minutes interval. The variables analyzed were: the joint amplitude in rest, the level of pain, the joint position sense (JPS) followed of isokinetic checking with electromyographic sign capitation. These data were analyzed in software SPSS 20.0. The normality was identified by Kolmogorov-Smimov examination and then, being used the ANOVA mixed model with significance of 5%. Outcomes: a decrease was observed at joint amplitude moreover, an immediate increase of pain wich increased after 24 and remained until 48 hours at all groups searched. There was not difference at the JPS. The variables peak torque, average peak torque, total work and mean power mean reduced until 48 hours after muscle lesion in all groups. Among the groups, there was no difference in EMG values and for any of the variables. Conclusion: The KT did not influence at the indirect clinical markers of muscle lesion induced by eccentric exercises in the elbow flexors in healthy people.
