Avaliação de gastrocitoproteção, mecanismo de ação e comparação do efeito da vitamina E (α-Tocoferol) nas formas natural e sintética

The aim of this study was to verify if α-tocopherol, the main substance of Vitamin E and also the one with the major antioxidant propriety, could offer citoprotection to a stomach damaged by alcohol. There are many forms of α-tocopherol, two forms of them were evaluated; d-l-α-tocopherol, the synthetic form and d-α-tocopherol, the natural form of α-tocopherol. Three experiments were made, all of them having absolute ethanol as the lesion agent, but the period and the doses changed in each of them. In the first two experiments, each group of animals received a different form of α-tocopherol and in the third experiment, they’ve received α-tocopherol p.o. for the period of seven days before the lesion agent was administrated. Moreover, immunohistochemistry assays were made from the stomachs samples of the third experiment to verify possible mechanisms involving nitric oxide and 2-cyclooxygenase. Satisfactory results of citoprotection have been obtained when the two forms were administered in the period of one week at doses of 100 mg/kg for synthetic form and 150 mg/kg for natural type. Nevertheless, the two forms didn’t differ statistically in their effectiveness against ethanol. The immunohistochemistry assays showed an increase of the levels of NO and COX2 in relation with the negative control, although there was no correlation between this increase and the gastroprotective effect. In conclusion, α-tocopherol has gastroprotection effect in some doses, but apparently there is no such a thing like the better the dose, the better the effect; that citoprotection don’t have a relationship with NO neither with COX2; the natural and the synthetic form don’t differ in their gastroprotection effect. More studies must be done looking forward an effective dose and also to understand the mechanisms underlay the citoprotection of α-tocopherol in the stomach

Um piloto de tradução alinhada e anotação em árvore sintática de dependência do grego antigo (AGDT 1.0) pela plataforma Alpheios.net com passagens de Heródoto

This study was developed based on Classical Greek Language classes, reading and translation of texts. There is also the presence of computer elements due to use of Alpheios digital platform. As an example of a larger proposal, this proposal aims at produce translation aligned with the Portuguese and syntactic annotation with the production of the Greek dependency trees. To achieve the goal, we chose Chapter 34, Volume 1 of The Histories from Herodotus. The methods adopted contain a list and description of the instruments and the morphological categories from the guide (manual rules of syntax tree). The procedures adopted are the description of the alignment process and of syntactic annotation. As study results, we have the production line translation and the syntactic annotation of the excerpt 1.34. It was concluded that the study of this text is relevant, because the lexical density of Herodotus it's interesting at future researchers and students that will use the digital platform Alpheios

Análise dos troncos radiculares, abertura da raízes e projeções cervicais de esmalte de furcas de molares superiores e inferiores: Estudo in vitro

Periodontal treatment of teeth with furcation lesions often have unpredictable results due to several factors that may hinder therapy or influence the progress of periodontal disease. Of these, the length of the root trunk may contribute to the early injury of the furcations or even cause complications for the application of the treatment; the opening of the roots can guide the type of treatment to be instituted and cervical enamel projections may hinder the instrumentation of the region or even act as a retention plate niche. Thus, the purpose of this study was measured using a digital caliper, root logs database 400 molar both the 1st and the 2nd and both upper and lower as well as analyze using appropriate index type projection cervical enamel and through appropriate classification the opening of the roots in order to guide the diagnosis and treatment plan. We conclude that there is variation in measures of root trunk between the faces of the teeth examined and that greater cervical enamel projection (ECP) correlates with a decrease in the length of the root trunk in the sample evaluated as the first molars have higher occurrence of roots with a degree of opening larger than the second molars.

Construção de instrumentos técnicos de astronomia para a divulgação científica: telescópio fotométrico de grande abertura e baixo custo

Although the popularization of astronomy in the last decade and the International Year of Astronomy, celebrated in 2009, there's a great lack in respect of quality instruments for astronomical disclosure. Thinking in this research about it, we intend to recuperate and elucidate a technique long forgotten: the metal mirror amateur telescope, once was done in the first reflecting telescopes. However, with the resources available today and given the high purity of the materials, our results were better than that obtained by the pioneers. We developed and built a large aperture telescope (250 mm diameter) and very bright (focal ratio = 4.0), versatile and portable. In our study was described step by step the process to fabricate the telescope. Through its first images captured of the Moon, we can illustrate its versatility both for use in outreach events and for use in amateur astronomy, because it is a primary focus capture system and can run registration of various astronomical events

Parâmetros construtivos de kirigami tridimensional de 90 graus de abertura

Origami folds and kirigami cuts merged in an oriental technique called Origamic Architecture (or 3D kirigami) that has intrinsic relationships with geometry as well as these paper arts. Despite its potential, it is not very used as a didactic resource because of the lack of parameters in its construction. There are many studies about programs development and computational language to help the design of pop-up structures, as origamic architecture is also known. However, there are few studies concerning the study of positioning the lines and creases, which is essential in the process of creating a 3D kirigami design, especially in the development of spatial perception of the figure. Limited to the 90o open type models, this article is about the establishment of some initial guidelines for design of an origamic architecture through visual elements as point, line and shape. It is presented some basic models to illustrate the constructive parameters detected as well as some models elaborated by the author, showing the viability of the guidelines established.

A influência da idade na percepção de dificuldade de abertura de embalagens PET para refrigerantes

Nowadays, there is an increasing demand for subjective aspects of the interface between human beings and the products and systems that surround them, whether in the workplace or at home. This study addresses the association of age and the perception of difficulty during a simulation of opening process PET bottles for soft drinks. During the activities, the subjects exerted their maximum torque forces, trying to open five different models of these packages, and then they assigned scores for perception in a scale. The results indicate that for some models, there were differences between levels of perceived difficulty between age groups.

Estratégias de política de desenvolvimento industrial pós-abertura econômica

This work intends to analyze the industrial policy strategies adopted by Brazil after economic liberalization. Initially will be compared the different views around the problem: the liberal model, which advocates less state involvement and horizontal policies, and the model that advocates active industrial policies with participation of the state and that are based on the South Korean model. The South Korean experience will be analyzed, especially for evaluation of consistency between objectives and instruments. Will be analyzed also the liberal strategies implemented by Brazil during the 1990s, and finally, the policies adopted after 2003, highlighting objectives, instruments and results by 2014

Climatologia de tempestades na área central do Estado de São Paulo usando radar meteorológico

A climatological characterization of storm properties during two summer seasons, viz. 1998-1999 and 1999-2000, based on observations from the Bauru S-band Doppler radar, was obtained from the TITAN Software of the National Center for Atmospheric Research (Boulder, Co), implemented at IPMet. Parameters, such as mean volume, mean area, mean and maximum echo tops, mean and maximum reflectivity, as well as speed and direction of precipitating systems were determined using the reflectivity >25, 30 and 40 dBZ and a volume >30 km3 as thresholds for storm identification. For the first time, the spatial distributions of these parameters were determined in the central State of São Paulo, based on radar observations. It was found that some preferential areas, where most of the convective activity was concentrated during the study period, were located along the Tietê River. The mean maximum reflectivity field has highlighted preferential regions for convection to develop over the metropolitan area of Campinas, which in turn was reinforced by the distribution of the echo tops and reflectivity >40 dBZ.
