Response to AIDS in Brazil: contributions of social movements and the sanitary reform

This paper briefly outlines how the political scenario and the mobilization of different actors have contributed to the construction of a public health policy in response to the AIDS epidemics in Brazil. Three factors are presented and discussed: the political context of the 1980s, characterized by redemocratization, growth of social movements, and consolidation of the Brazilian health care reform; the socio-cultural context of the 1970s and 1980s, characterized by achievement of individual freedom, which was key to the organization of the AIDS movement; and finally the actions carried out in the international scenario to support the sustainability of the Brazilian domestic policy and the reinforcement of a global response to face the epidemics in lower-middle income economies.

BhSGAMP-1, a Gene That Encodes an Antimicrobial Peptide, Is Developmentally Regulated by the Direct Action of 20-OH Ecdysone in the Salivary Gland of Bradysia hygida (Diptera, Sciaridae)

Recently we have shown that BhSGAMP-1 is a developmentally regulated reiterated gene that encodes an antimicrobial peptide (AMP) and is expressed exclusively in the salivary glands, at the end of the larval stage. We show, for the first time, that a gene for an AMP is directly activated by 20-OH ecdysone. This control probably involves the participation of short-lived repressor(s). We also found that the promoter of BhSGAMP-1 is not equipped with elements that respond to infection, provoked by the injection of microorganisms, in the salivary glands or in the fat body. We produced polyclonal antibodies against the synthetic peptide and found that the BhSGAMP-1 peptide is secreted in the saliva. The BhSGAMP-1 gene was also activated during the third larval molt. These facts confirm our hypothesis that this preventive system of defense was selected to produce an environment free of harmful microorganisms in the insect`s immediate vicinity, during molts. genesis 47:847-857, 2009.

The Great appropriation: Political Possibilities Since 1974

Argued that a new cadre of 'intellectual journalists' (such as Paul Kelly), unlike scholars of Graham Maddox's standing, have usurped critical appraisals of the possibilities of politics. This new anti-democratic liberalism wrongly suggests that political achievements reached when Australia was less rich (such as compulsory industrial arbitration) now need to abandoned, subordinating national well-being to an international policy orthodoxy.
