Efeito da oxigenação hiperbárica no reparo ósseo de ratos diabéticos

The chronic state of hyperglycemia due to diabetes mellitus affects multiples organs impairing life quality. In bone, diabetes alters strength and mineral density and also suppresses the osteoblast activity, leading to an unbalanced bone healing process. Hyperbaric oxygen therapy (HBO) is suggested as an adjuvant treatment to accelerate bone repair. This study evaluated the effects of HBO in the number of mast cells and in new bone formation at the initial stage of bone repair in normoglycemic and diabetic rats. It was hypothesized that HBO treatment may improve bone repair in diabetic bone. The rats were equally divided in four groups: Control (C); Control + HBO (CH); Diabetes (D) and Diabetes + HBO (DH). Diabetes was induced by streptozotocin (65mg/kg) and femoral bone defects were created thirty days after diabetes induction in all groups. HBO initiated immediately after surgery procedure and was performed daily, for 7 days, in the CH e DH groups. Seven days after surgery, all animals were euthanized. The femur diaphyses were removed, fixated, decalcified and processed for paraffin embedding. The semi-serial histological sections obtained were stained with Hematoxylin-Eosin (HE), Mallory Trichrome and Toluidine Blue. The qualitative analysis was conducted in the histology slides stained with HE, where it was evaluated the morphological aspects of bone repair in the lesion area, observing the presence of clot, inflammatory cells, granulation tissue, type of bone tissue, morphology of bone cells, and thickness and organization of bone trabeculae. In the slides stained with Mallory Trichrome and Toluidine Blue were evaluated the percentage of new bone formation and number of mast cells, respectively. The qualitative analysis showed that the CH group presented a more advanced stage of bone repair compared to the C group, showing thicker trabeculae and greater bone filling of the lesion area. In D and DH group, the lesion area was partially filled with new bone formation tissue and presented thinner trabeculae and fewer areas associated to osteoclasts compared to control group. The histomorphometric analysis showed a significant improvement in new bone formation (p<0.001) comparing CH (38.08 ± 4.05) and C (32.05 ± 5.51); C and D (24.62 ± 2.28 and CH and DH (27.14 ± 4.21) groups. In the normoglycemic rats there was a significant increasing in the number of mast cells (p<0.05) comparing C (8.06 ± 5.15) and CH (21.06 ± 4.91) groups. In conclusion, this study showed that diabetes impaired bone repair and HBO was only able to increase new bone formation and the number of mast cells in the normoglycemic animals.

Identidade e imagem da marca: uma análise comparativa em uma empresa do setor de serviços de telecomunicações

In a highly connected society, avid for information and technological innovations, constantly changing the consumption patterns, the brand management strategy occupies a growing place. Allied with the increased competition among companies, the brand that can differentiate in consumers’ minds becomes strong. This aspect is even more important in the service industry, where the consumer experience, the definition and support of the brand’s values are vital to the continued strength of both your identity and image. These aspects are seen as a process of communication in which the way the image is developed in the minds of consumers comes from how identity is constructed and transmitted to them (DE CHERNATONY; DRURY; SEGAL-HORN, 2004). Considering the dynamic and complex scenario, this study aims to identify and analyze the possible convergences or divergences between the identity built by the organization and the brand image perceived by consumers of a telecommunications services company. To achieve this objective, the model proposed by De Chernatony, Drury and Segal-Horn (2004) was used as a theoretical basis, which addresses the transformation of identity in brand image, specifically under the perspective of Pontes (2009). For him, customers are more motivated to buy and consume products that they believe that take a complementary image that they have of themselves, and proposes the existence of multiple selves: the perceived, which refers to the employees and the organization’s management opinions on the brand; the ideal, which deals with effective brand identity thought by its leaders, the vision of what it should be; social, which shows how managers think that consumers see it; the apparent, formed by the image of the brand by customers; and finally the real self, that would be an integrated composite of all of these visions. In this regard, a case study was made in a telecommunications company with regional actions, from a qualitative and quantitative approach. It was identified the company’s vision through semi-structured interviews with marketing managers and analysis of documents related to the brand strategy. The point of view of consumers was addressed for text mining techniques applied to internal unstructured data coming from the collection of posts made on Facebook and Twitter, related to the brand, and customer interaction with the company through these social networks. The results showed the importance of the concepts of identity and brand image, and how they are interrelated. Moreover, the qualitative analysis it was shown that the vision of marketing executives is quite close and in line with the Brand Book, showing that there is a cohesive and well disseminated speech internally in the organization. On the other hand, when evaluating the customer's point of view there was no specific comments on the brand, and it was not possible to identify the evaluation of Algar Telecom image by consumers. Nevertheless, other relevant aspects could be identified for the consolidation of the brand identity, as the occurrence of a number of complaints, especially regarding the internet as well as the concern of customers for the quality of the provision of services.

Arcabouço jurídico normativo pedagógico da lei federal 10.639/2003 na universidade federal de Uberlândia: avanços e limites

This search addresses the public policies that directly or indirectly corroborate for the implementation of the Brazilian Law number 10.639/2003 in Federal University of Uberlândia and it analyzes the affirmative actions in this context. The study aims to answer some questions such as: Why we have found difficulties in implementing the Law 10.639/2003 and its correlate legislation in the institutions responsible for teachers formation, particularly in the courses of History, Visual Arts, Portuguese Language and Literature and Education teachers? We started from the hypothesis that implementing the Law 10.639/2003 is considered by popular movements that fight for the emancipation of black population and for its rights consider such actions as a form of eradicating racial and ethnic prejudice which are still present in our society. The methodology is based on case study, which allows the triangulation to other methodological approaches such as qualitative analysis and bibliographic search. The investigation instruments were: I. Bibliographic sources including books, papers, periodic and so one; II. Documental sources: specific legislation on the theme (Brazilian Federal Law 10.639/2003, Resolution CNE/CP 1/2004 and others; III. Oral sources obtained from semi structured interviews with coordinators of the selected Graduation courses. Critical multicuturalism according to McLaren (1999) allowed us to approach our research object in order to understand its plural characteristics, specially reading the different aspects that permeate the relationship between culture and identity, cultural differences and power relationship in modern society. In the study, we did not perceive the involvement of the Higher Education professionals in order to implement Law 10.639/2003. The problem perceived for implementing the law and its pedagogical normative legal framework is the personal and institutional attitude, because every subject involved in it has a direct responsibility. We cannot believe that the institutions may claim lack of knowledge and research in the area as impediments to implementing the disciplines and the pedagogical contents concerning to the Law nor contracting researcher experts and scholars on this topic to compose the frames of the University.
