Avaliação da influência do estresse em modelo experimental de colite por administração de Ácido Trinitrobenzenosulfônico (TNBS) em concentração subinflamatória

Inflammatory bowel disease (IBD) is a chronic and relapsing disease caused by exaggerated response of the immune system. It represents a significant health problem by limiting the quality of life and being the main risk factor for colorectal cancer. Despite of its importance, the high worldwide incidence and being the object of research for several decades, the etiology remains unknown. Studies indicates an interaction between genetic and environmental factors which together with the intestinal microbiota, leads to an uncontrolled immune response. One of the aggravating environmental factors often discussed is stress, as the daily life of the population in general is increasingly rushed. In order to demonstrate the influence of stress on IBD, this study aimed to standardize an experimental model of colitis induced by instillation of a trinitrobenzene sulfonic acid (TNBS) noninflammatory concentration plus exposure to stress that intensify the inflammation. Therefore, an experiment was done to determine what would be the noninflammatory concentration. In this step, four different concentrations of TNBS (1, 6, 12.5 or 40mg/ml) were tested and the lowest concentration capable of inducing a noninflammatory response in the gut was defined as 1 mg/ml. Then, a second experiment was performed which induced colitis and exposed the animals to restraint stress. The results, however, showed that this stimulus was not enough to exacerbate the damage caused by the 1 mg/ml concentration of TNBS in the colon. With some changes in the protocol, the third experiment associated cold and restraint, as well as changes on the day of euthanasia, which occurred immediately after the stress session. The results of myeloperoxidase activity measurement were unexpected due to the noninflammatory concentration of TNBS caused an intestinal inflammation similar to the concentration of 40 mg/ml. However, the results of glutathione quantification and the corticosterone ...

Levantamento e análise de técnicas utilizadas nas operações de emergência de derramamento de óleo em ambientes costeiros e fluviais

This present paper aims to identify the main response techniques for coastal and fluvial environments and analyze impacts on the application of these techniques. The literature review allowed us to understand since the establishment of first environmental sensitivity index map, in coastal and fluvial environment, until the possible impacts generated by the application of cleanup techniques in both environments. Studies related to freshwater environment are less common compared to coastal environment. For both environments the same techniques may be employed, as well as containment and recovery, or removal of oil in the affected areas. The most serious environmental impacts generated are due to the poor choice of technique to be applied or the lack of training of the cleaning crews. In Deepwater Horizon accident, Gulf of Mexico, 2010, application of dispersants, resulted in a mixture of oil and dispersing 52 times more toxic than the oil itself. In Brazil, the technique of vegetation removal by the cleaning staff in the accident on the river Guaecá, 2004, resulted in unnecessary elimination of vegetation, increasing the volume of waste. It was concluded that the freshwater environment often suffer more impacts by applying the techniques, once is necessary to access the banks, which normally have more vegetation and organisms than shoreline of coastal environment

Manejo pré-abate de bovinos

The pre-slaughter moment begins with the animal´s loading on the farm and ends up in its drain. It is a period in which the animal is under physical stress caused by hunger, thirst, fatigue, injuries, and extremes of temperature and psychological stress, due to restraint, handling, innovation and fear. Stress and inappropriate handling bring bad consequences for the final product´s quality, requiring better handling conditions, facilities and equipment. Examples of consequences of mishandling: meat with abnormal color, DFD meat (dark, firm and dry), reduced product´s shelf life, bruises and broken bones in carcasses. The operators should be trained and oriented on the basic principles of biology, behavior and management of cattle. At every step of the pre-slaughter moment, the animals should be handled calmly and quietly to avoid excitement and stress. Operators should avoid shouting, whistling or any noise since cattle have very sensitive ears and can become stressed. If the animals refuse to move, the cause of the problem should be determined

Composição florística e fitossociológica de três fragmentos de floresta ribeirinha em Ajapi, Rio Claro - SP

A vegetação ribeirinha é conhecida como o conjunto de formações que se encontram associadas aos corpos d’água, ocorrendo ao longo dos cursos d’água e no entorno de nascentes, formando um mosaico vegetacional. É de vital importância na proteção de mananciais, controlando a chegada de nutrientes, sedimentos e a erosão de ribanceiras, atua na estabilidade térmica e abastece o lençol freático a partir da contenção de águas pluviais, além de exercer um papel fundamental como corredores ecológicos de fluxo gênico animal e vegetal. No Brasil, há legislação que protege tais áreas, entretanto, estas vem sofrendo sistemática degradação por desmatamento, despejo de esgotos domésticos e industriais, canalização e desvio de cursos d’água. O estudo presente teve como objetivo caracterizar a florística e a estrutura fitossociológica de três fragmentos do ambiente ribeirinho localizados na Fazenda Água Branca, em Ajapi, Rio Claro - SP. Através de parcelas de 10x10m, foram amostrados todos os indivíduos com PAP ≥ 10cm. Foram estabelecidas 16 parcelas na vegetação ribeirinha com influência fluvial sazonal ao longo do Ribeirão Claro, tratadas no trabalho como floresta ciliar.

Estudo sobre uma turbina a gás instalada em uma refinaria de petróleo

The gas turbine (GT) is known to have: low cost of capital over the amount of energy, high flexibility, high reliability, short delivery time, commissioning and commercial operation at the beginning and quick departure. The gas turbine is also recognized for its superior environmental performance, manifested in air pollution containment and reducing greenhouse gases (Mahi, 1994). Gas turbines in simple cycle mode (SC) have long been used by utilities to limited power generation peak. In addition, manufacturing facilities use gas turbines for power generation units on site, often in combination with the process of heat production, such as hot water and steam process. In recent years, the performance of industrial gas turbines has been improved due to significant investments in research and development, in terms of fuel to electricity conversion efficiency, plant capacity, availability and reliability. The greater availability of energy resources such as natural gas (NG), the significant reduction of capital costs and the introduction of advanced cycles, have also been a success factor for the increased use of gas turbines to load applications base (Poulikas, 2004). Open Cycle Gas Turbine with a greater degree of heat to the atmosphere may alternatively be used to produce additional electricity using a steam cycle, or to compose a cogeneration process. The combined cycle (CC) uses the heat from the gas turbine exhaust gas to increase the power output and increase the overall efficiency of more than 50% second (Najjar, 2001). The initial discovery of these cycles in the commercial power generation market was possible due to the development of the gas turbine. Only from the 1970s that gas turbine inlet temperature and therefore the exhaust gas temperature was sufficiently high to allow a better efficiency in the combined cycle ...

Ensaios laboratoriais para a determinação da resistência de conexão entre geogrelhas de PVA e blocos segmentais

During the retaining wall project in soil reinforced with geogrids and face milling system for segmental blocks is essential to determine the maximum connection resistance between the block and the geogrid. Thus, the aim of this study was to analyze the connection resistance based on ASTM D- 6638-01 between the segmental block model MW of Muros Terrae® company with the geogrids model Fortrac® M 35 / 20x20, Fortrac® M 55 / 30x20, Fortrac® M 80 / 30x20 and Fortrac® M 110 / 30x20 of HUESKER Synthetic GmbH using gravel 1 as a filling material. As a result, the resistance curves were obtained for the four models of geogrids and was described how it fracture. An additional investigation was the average gain connection resistance percentage when it is applied to geogrid a second layer instead of a single layer. The average percentage gains in the connection resistance to the geogrids model Fortrac® M 35 / 20x20, Fortrac® M 55 / 30x20, Fortrac® M 80 / 30x20 and Fortrac® M 110 / 30x20 were, respectively, 63.20 %, 63, 47%, 62.23 % and 51.34 %. Finally, we made a comparative analysis of the results of this study with those obtained by Guimarães (2006), Urashima et. al (2008) and Almeida and Toma (2011) to evaluate which combinations offered higher connection resistance

Algumas reflexões sobre a condição da mulher brasileira da colônia às primeiras décadas do século XX

This article, about reflections on the condition of Brazilian women from the Colony to the first decades of the twentieth century, reveals the historical position of them and the attitudes and behaviors related to gender and sexuality. Subdued, it was treated as a sexual object, arousing all sorts of misogyny by men. Rebel, veiled or ostensibly, could serve their own desires. Throughout history, the Church and medical institutions which jointly accounted for, significantly, established the meaning and place of women. In Colony period, the woman is a ward from the Catholic ideology, but from the nineteenth century, after Independence, this power control arises to Medicine. The physician submits the religious discourse, naturalizing the status of women as one that breeds, namely the insertion of the medical issues of family scientifically legitimate colonial patriarchy. This is accentuated in the early twentieth century, when medicine consolidated setting standards and rules for marriage, to motherhood and family life. We note how the feminine universe was (and it is nowadays) ambivalent, with "one foot" in virtue and another in sin, with a tendency to contain and another to trespass. On the one hand we have the home and motherhood, validated in marriage, in which the woman is cared for and dependent on her husband. Reflecting on the motherhood of Virgin Mary, comes to the sacred dimension of the idealized woman saint by the Church. At the same time, however, feels the need for freedom, identity and independence, needing to give a voice to the desire to have their sexuality and all that it is due in full. The manifestation of the desire and the call for sexual satisfaction, and put in permanent conflict personal, psychological and social split between moral entrenched across generations and cultural transformations resulting from decades of the 20th Century.

A formulação de uma corrente urbanística: uma (re)visita às teses de Anhaia Mello para São Paulo

The present article aims to elaborate an objective analytical panel, initially from the 1920- 1930 when Luiz Ignácio Romeiro de Anhaia Mello, cathedratic in the urban question, started to quote a series of authors and American plans as references to their reflections, mainly when the point was the verticalization or not at São Paulo City. From a broad bibliographic research with the systematization of the register from the debate between Anhaia Mello, this article intends to point out how the transposition of the urbanistic conceptions to the academic environment happened and, at the same time, the legal normatization of the São Paulo City that resulted in the creation of a draft of the regulations for use and occupation of the soil. The systematizations and analysis were based in a broad reading of the bibliography and documental sources that refer to the proposed theme. The books of the library of FAU-USP, specifically the one from SAGMACS – Sociedade de Análises Gráficas e Mecanográficas Aplicadas aos Complexos Sociais ( Society of Graphical Mechanical-Graphic Analysis Applied to Social Complexes) -, aiming to select papers and the collection of Anhaia Mello´s family, so that a reconstruction of the intellectual and professional journey of the Urbanism Professor. The systematization of the collected data and posterior comparison with the bibliographical study was fundamental for the reconstruction of the reflection of Anhaia Mello about the ways of the urban streets and roads at Sao Paulo City should be lead to on the middle of the XX century having as a guideline the debate between Anhaia Mello – very common on the 1950s for less important countries when dealing with the organization of the size of industrial metropolis. It was possible to identify the crystallization of one urbanistic proposal for the city: the from Anhaia Mello, that bet on the reversion of the metropolitan cycle by stopping the urban growth by the application of the theoretical conception of the garden city.

Tendência de crescimento facial em ortodontia e ortopedia funcional dos maxilares

The knowledge of the facial growth trend is very important in orthodontic treatment. A lateral headfilm is recommended in all young patients undergoing a preorthodontic guidance program to anticipate the best time to begin any mechanical procedures and the possibilities to determine the type of facial growth trend. In type A it will be observed that the middle and lower face are growing forward and downward in unison, with no change in ANB angle. Type B growth trends reveals that growth is downward and forward, with the middle face growing forward more rapidly than the lower and in type C the lower face is growing downward and forward more rapidly than the middle face revealing a decrease in the size of the ANB angle.

Eficiência do aparelho Herbst bandado na correção da Classe II divisão 1 -relato de caso

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.

Alterações dimensionais em pacientes submetidos à expansão rápida da maxila com aparelho do tipo Haas

The maxillary atresia is a alteration in the transverse dimension that can result in a unilateral or bilateral crossbite. For correction of atresia of the upper dental arch appliances with the intent to expand the arch of orthopedic or orthodontic manner are used, obtaining across-compatibility between the dental arches. The purpose of this study was to evaluate the dimensional changes of the maxillary in patients in the mixed dentition with atresia in the upper dental arch, using occlusal radiographs taken before, after rapid maxillary expansion and after removal of the appliance. Methods: the sample consisted of 35 patients who used the appliance type conventional Haas, in the mixed dentition, according to the standard protocol for installation, activation, containment and removal of the appliances rapid maxillary expansion. Results: the results confirm that the suture opening occurs in greater quantities in the anterior (4.3 mm) than posterior to (3.74 mm), representing a triangular opening of 7 degrees on average with the posterior opening 87% of the quantity of anterior opening. The molars region expanded about 5 mm, and the base bone 3.7 mm, representing a 74% bone expansion of the expansion teeth.
