Modelos de tratamento para adenocarcinomas de próstata tratados por radioterapia conformacional 3D

Radiotherapy is a branch of medical physics related to the treatment of malignant neoplasm, being an important instrument in the fight against cancer, when combined with the effort of a multidisciplinary team, composed of, physicians, physicists, nurses and technicians. Every year more than 3.5 million new cases of cancer are recorded in the world, being the prostate cancer responsible for approximately 25% of this amount (INCA and IARC, 2008). In this type of cancer, radiotherapy is a method indicated for treatement. The technological advance in this area over years has allowed a greater accuracy in the tumor location, more conformation of the radiation beam around the tumor, reducing the dose in healthy tissues and a consequent dose increase on treatment (Bedford et al., 1999). A radiotherapy planning, in which the physicist develops an important role, is composed of several steps, including choosing the best configuration of treatment beams. This choice has a close relationship with success of therapy and is critical to achieve the best distribution of dose inside the tumor and expose the least as possible the healthy tissue to radiation. In this work, two options for setting up camps in the first phase in a treatment of prostate cancer were simulated in computer planning: 4 fields orthogonal or “Box” with gantry angles in 00, 1800, 2700 e 90° and 4 fields angled or “X” (1350, 450, 3150 e 2250). The percentage of the rectal volume exposed to 40, 50, 60, 72 and 76 Gy should be limited to 60, 50, 25, 15 and 5% respectively (Greco et al., 2003). The femoral toxicity have limited dose by 70% of the total dose prescribed in a prostate treatment (Bedford et al., 1999). The planning of 27 patients with prostate adenocarcinoma submitted to 3D conformal radiotherapy were accompanied. As a result, it was assessed that the best TCP (tumor control probability)...

Estatuto do índio, direito indígena e impacto ambiental: aldeias Guarani do Jaraguá (SP)

In Brazil, there are three main codes that surround the issue of right or possession of various lands according to concepts of ownership or purchase. When it comes to indigenous issues in Brazil is difficult to say which legal code applies more fairly the native population of the country. In the case of the Indians who have their reserves near urban areas there is such a conflict of laws becomes more evident and takes even greater than in other regions of Brazil. As is the case in the indigenous villages of the District of Jaragua in Greater São Paulo, the Tekoá YTU and Tekoá Pyau. The two villages are located in northeastern São Paulo and currently are surrounded by continuous growth and disorderly city of Sao Paulo while their inhabitants fight to preserve the customs and traditions of the Guarani people. They prevail on the City Statute (2001), the Indian Statute (EDI) Environmental Laws and the National Council of Environment (CONAMA) and the Forestry Code, the latter solely because they are near the State Park Jaragua - area environmental preservation

Memória de onde, memória de quem

The spatial formation of Rio Claro city preserves several features of the problematic transition from the slave to remunerated labor in the late 20th, when the tacit ethnic bipolar sociability standard emerged, imprinting “black” and “white” forms to the city’s urban space. The ethnic social clubs José do Patrocínio and Tamoio, are two objects of ethnic groups’ exclusive use. Such ethnic social clubs indicate the existence of conflicts in their formation, as well as in their present existence, they are forms that preserve in themselves the codes and histories of the local black movement’s fight for their rights and for an autonomous place in the local society. In the present context the spaces are increasingly subjected to commercial interests and the spirits are embedded in confusion. What is the value of these spaces for the subjects who built them? The versions and narratives from oral accounts will allow us to understand the existing dimensions in the relation between the places and the memory, evidencing the importance of the patrimony and the patrimonial policies to the cities in the present historical period of geographic space globalization

Movimento estudantil: a juventude brasileira em 1968 e em 2008 a partir das ocupações da Universidade de Brasília

The hypothesis guiding this work is that the student movement of 1968, inserted into a scene of great social movements contrary to the present political system, showed great expression in its demonstrations even considering the fact that in a dictatorship there was significant intolerance of divergent views to the military regime, which, of the student movement of 2008, inserted into a scene of mobilizations contrary to the educational system and the corruption that permeated it. The aim of this study is to investigate the myths that permeate the image of students, through a comparison between the Brazilian student movement, highlighting the students at the University of Brasilia from 1968 to 2008, with the specific objective of analyzing if the student movement lost strength of mobilizing in support of their fight flags. The question may be answered from the youth of the 1960s characterized by revolutionary, in which the possible advances and retreats performed in 40 years of history of the student movement, which seems to have lost its revolutionary feature

(Des)Compromisso social e sofrimento: o processo de exclusão de travestis e transexuais do interior de São Paulo

Transvestites and transsexualsface everyday intense process of exclusion. The un(un)involvement to those people ethically and politically is a fact and comes from the State and Civil Society. The aims of this article are to analyzehow transgenderexperience their construction of identity in aheteronormative social context; the public health assistance, work and incomepursuit. The methodology used was qualitative action research. The conclusion is that suffering is the result of a process of right’s fight and pursuit for health, assistance and work. The situations of being treated as inferior persons, with no social value are experienced repeatedly.

A construção do projeto político-pedagógico das escolas do campo do município de Araraquara

This study aimed to analyze the process of developing and implementing a politicalpedagogical project for rural schools in the city of Araraquara, focusing on one of the schools served. This is an ethnographic qualitative study. The instruments of data collection were participant observation, semi-structured interviews and documentary analysis. It was observed are a change in the community organization throughout the process, with regard to a more active attitude on the part of its members, who have pursued other means to claim the fulfillment of their demands by the Government and relevant institutions, which points to the pedagogical character of participation in the movement to fight for the education they desire. It was also noticed a process of re-signification by the subjects, of their own community identity while seated in an agrarian reform project, as well as a more effective participation of those in everyday life and school organization. It was also observed changes in indicators of school, with an increase in the achievement of students as well as reducing the dropout rate to zero, and the reduction of absenteeism of teachers.

Corporalidade brasileira na fabricação da identidade nacional

This paper discusses how, through the creation of Embratur (Brazilian Tourism Company) in 1966, an idealized Brazilian female body was constructed and used to help manufacture a national identity, reinforcing the stereotype of the sexualized Brazilian woman. As it was often associated with sex tourism, this stereotype received much criticism and led to a negative image of Brazil abroad. However, in the 1990s the official tourism lobby softened the “sexy tone” of its discourse, and in 1999 Embratur received an award from the World Tourism Organization for its campaign to help fight the exploitation of children and youth by sexual tourism. In order to better understand how this change in the idealized Brazilian female body unfolded, it is important to deconstruct beauty standards – focusing on those that apply to Brazilian women as seen from abroad – and their relationship to modern consumer culture. Assuming that the cultural analysis of the female body emerges as an important issue in the field of Social Science, the focus on body image can be viewed as a key element in discussions about the construction of national identity.

Gestos de subjetivação: as dificuldades para realizar uma história do corpo e da sexualidade

The article presents, from the Analysis of French Discourse, different gestures of reading and interpretation of the body and sexuality at various times in history. It demonstrates that such gestures reading are the fruit of experience that each society sets about their cultural values and norms in each period, both in the first civilizations to the economy of sex for birth control and the survival of the group and in the Medieval Christianity control of sex in the fight against sin. Each society according to Michel Foucault, establishes a system of knowledge and power to order and classify the type of body and citizen you desire, like the city of Sparta with its regime of knowledge and training of the soldier and in Athens with the democratic regime in the formation of the political, or contemporary society in the formation of the body of perfect proportions that meet the stipulations of the market.

Variable assessment of wing colouration in aerial contests of the red-winged damselfly Mnesarete pudica (Zygoptera, Calopterygidae)

Wing pigmentation is a trait that predicts the outcome of male contests in some damselflies. Thus, it is reasonable to suppose that males would have the ability to assess wing pigmentation and adjust investment in a fight according to the costs that the rival may potentially impose. Males of the damselfly Mnesarete pudica exhibit red-coloured wings and complex courtship behaviour and engage in striking male– male fights. In this study, we investigated male assessment behaviour during aerial contests. Theory suggests that the relationship between male resource-holding potential (RHP) and contest duration describes the kind of assessment adopted by males: self-assessment, opponent-only assessment or mutual assessment. A recent theory also suggests that weak and strong males exhibit variations in the assessment strategies adopted. We estimated male RHP through male body size and wing colouration (i.e. pigmentation, wing reflectance spectra and transmission spectra) and studied the relationship between male RHP and contest duration from videodocumented behavioural observations of naturally occurring individual contests in the field. The results showed that males with more opaque wings and larger red spots were more likely to win contests. The relationships between RHP and contest durations partly supported the self-assessment and the mutual assessment models. We then experimentally augmented the pigmented area of the wings, in order to evaluate whether strong and weak males assess rivals’ RHP through wing pigmentation. Our experimental manipulation, however, clearly demonstrated that strong males assess rivals’ wing pigmentation. We finally suggest that there is a variation in the assessment strategy adopted by males
