High bax expression is a good prognostic indicator in acute myeloid leukaemia

Most cytotoxic drugs kill cells by instigating the process of apoptosis and it has been suggested that apoptotic markers may provide an indication of tumour chemosensitivity. The aim of this study was to determine if such a relationship exists in acute myeloid leukaemia (AML). The levels of spontaneous apoptosis, bcl-2 and bax were evaluated in 56 newly diagnosed AML patients to determine if they correlated with a response to cytotoxic therapy. Spontaneous apoptosis was lower, but bcl-2, bax and the bcl-2/bax ratio were higher in AML compared with normal individuals. AML patients with high bax expression at diagnosis had significantly better prognosis for disease-free survival, event-free survival and overall survival (P = 0.016). In the standard risk group, high bax expression was in keeping with significantly improved survival. Multivariate analysis revealed bax to be an independent predictor of survival. There was a significant reduction in bcl-2 and bax expression when AML patients entered complete remission and also in relapsed AML patients who entered a second remission. This study suggests that bax is a useful prognostic indicator in AML and may assist with therapeutic decision-making for patients in the standard risk category.

Dogs in the paradise: The influence of the cynical philosophy in the construction of the myth of the good savage

This paper studies the influence of cynic philosophy in the construction of the myth of the good savage. In the first part it studies the importance of cynicism in the XVI century and how the cynic influence of Erasmus, More and Montaigne was fundamental to the way that Europe approached the American indigenous. In the second part it studies the cynic motives that could have influenced in the construction of the myth of the good savage.

The Architecture of Seduction: An Analysis on Digital Architectures within Consumer Society

Currently new digital tools used in architecture are often at the service of a conception of architecture as a consumer society’s cultural good. Within this neoliberal cultural frame, architects’ social function is no longer seen as the production of urban facts with sense of duty, but as a part within the symbolic logic that rules the social production of cultural values as it was defined by Veblen and developed by Baudrillard. As a result, the potential given by the new digital tools used in representation has shifted from an instrument used to verify a built project to two different main models: At the one hand the development of pure virtual architectures that are exclusively configured within their symbolic value as artistic “images” easily reproducible. On the other hand the development of all those projects which -even maintaining their attention to architecture as a built fact- base their symbolic value on the author’s image and on virtual aesthetics and logics that prevail over architecture’s materiality. Architects’ sense of duty has definitely reached a turning point.
