This paper aims to analyze Brazilian athletes' participation in the South American Olympic Games held in 1907 in Montevideo/Uruguay through the publications published by the press in the cities of Rio de Janeiro and São Paulo. The sources selected for this purpose were the following newspapers: Correio Paulistano, Jornal do Brazil, O Paiz and O Século. There is evidence of various tensions in the incipient Brazilian sporting sphere, which implied definitions of amateurism and professionalism, as well as disputes over the sporting protagonism between Rio de Janeiro and São Paulo. In conclusion, the article points out that, even in this scenario of tensions, the Brazilian press tried to produce its first sports heroes. [ABSTRACT FROM AUTHOR]

This article aims to map Brazilian ethnicities connected to the Internet and observe indigenous net-activist communication practices, during the Covid-19 pandemic, as a way of resisting and coping with cosmophagic processes based on the analysis of three Instagram profiles: @midiaindiaoficial, @apiboficial and @visibilidadeindigena. From the analysis, it was possible to perceive how the profile communications are strongly marked by 1) awareness and denunciation of violations of indigenous rights; 2) dissemination of achievements and events and 3) articulation of mobilizations, occupations and organized interventions. In addition, it is clear that the Instagram network is now inhabited by indigenous peoples as an ecosystem of strive and resistance. [ABSTRACT FROM AUTHOR]

This essay seeks to reflect on the reasons that led sport not to consolidate itself as a social right for every Brazilian citizen. To achieve this goal, a socio-historical analysis was carried out, showing how the sport was inserted in the state sphere of the country from the 1940s until the victory of the extreme right in the presidential election of 2018. Even with sports becoming a social right provided for in the 1988 constitution, successive governments did not make them a cultural element accessible to the Brazilian population. In conclusion, it is pointed out that the organization of the Olympic Games was a missed opportunity for Brazil to realize the ideals foreseen in the 1988 constitution, since the country only opted to host the competitions and did not really seek to become a sports nation. where its practice was accessible to most of its population.

The Public Relations activity carries a series of challenges considering teaching, learning and market. Through literary review and qualitative research, we introduce some historical elements of Public Relations and the adversities that the activity crossed by virtue of its authoritarian insertion in Brazil, shining a light on the connection between the education offered by the Institutions and the requirements of the market. From this article, we have noticed that some needs of the market trends for Public Relations arise from the historical gap between teaching and learning and the problems faced by the lack of affirmative policies of the profession through the class organs. We infer, consequently, that these aspects exalt the challenges and the opportunities related to the teaching of Public Relations, since in a country pervaded by corruption, Public Relations are gaining in the construction of a more just world through the truth.

A successful pregnancy requires a series of interactions, mediated by hormonal, molecular and immunomodulation phenomena. One of these interactions is between the endometrium and the blastocyst, before and during the implantation process. The objective of this literature review is to complement what is described in the classic human embryology literature on endometrial-blastocyst interaction. The bibliographic search was carried out in the MEDLINE database using the terms "implantation", "endometrium" and "embryo", and a manual search was carried out, which included articles from non-indexed journals, textbooks and atlases. Inclusion and exclusion criteria were considered for the selection of articles and other bibliographic resources, including human studies, review and experimentation articles, published in the last 5 years. Articles with animals as experimental subjects, in vitro fertility studies, associated pathologies and articles not related to the subject were excluded. When the selection was completed, the complete texts were examined, in which the exclusion criteria were applied again The search yielded a total of 560 articles, whose analysis of titles and abstracts resulted in 475 excluded works, in relation to different exclusion criteria described above. Therefore, 85 articles were obtained, in which the complete text analysis was performed. From these articles, a total of 34 studies were obtained and the contents selected in this review were: Endometrium, Endometrium trophoblast, Aposition, Adhesion and Migration-Invasion. During the implantation, aninteraction between the endometrium and the trophoblast is generated, with the participation of regulatory molecules of proliferation and differentiation, such as hormonal, molecular and gene expression factors. However, the specific mechanisms of action and interaction must continue to be investigated, to answer questions in the field of human growth and development. [ABSTRACT FROM AUTHOR]
