Thermal analysis of chitosan based networks

In this work two kinds of material were studied: chitosan cross-linked with glutaraldehyde and in a blend with PEO. The resulting products as well as chitosan and PEO raw materials, were analyzed by TG/DTG, DSC and DMTA to determinate the in?uence of cross-linking and PEO addition on thermal properties of the resulting materials. It was observed by thermogravimetry that the water-polymer interaction will be different for the cross-linked material compared to the blend, according to the specific site availability. The in?uence of such modifications (cross-linking and PEO addition), on chitosan thermal stability was also studied. The DSC results showed a good agreement with the TG/DTG results, reinforcing the interpretation given for TG/DTG results. DMTA results indicate that glass transition temperature is around 50 degrees C for the polymer under study. (c) 2005 Elsevier Ltd. All rights reserved.

Characterization of ndh gene of isoniazid resistant and susceptible Mycobacterium tuberculosis isolates from Brazil

Resistance in Mycobacterium tuberculosis to isoniazid (INH) is caused by mutations in the catalase-peroxidase gene (katG) , and within the inhA promoter and/or in structural gene. A small percentage (~ 10%) of INH-resistant strains do not present mutations in both of these loci. Other genes have been associated with INH resistance including the gene encoding for NADH dehydrogenase (ndh) . Here we report the detection of two ndh locus mutations (CGT to TGT change in codon 13 and GTG to GCG change in codon 18) by analyzing 23 INH-resistant and in none of 13 susceptible isolates from Brazilian tuberculosis patients. We also detected two isolates without a mutation in ndh, or any of the other INH resistance-associated loci examined, suggesting the existence of additional, as yet to be described, INH resistance mechanisms.

Contando estórias e inventando metodologias para discutir a violência contra as mulheres

In this article I write about the importance of creating alternative methodologies to work with violence against women in the field of psychology. Artistic productions like literature, theatre and storytelling, among others, make it possible to question fixed binary identities in gender regulation and may enable the reconstruction of identitary rules by means of original enunciations and gestures, which give occasion to new maps that can embrace differences and refute normalizations. I bring the possibility of thinking the insertion of the psychologist in this debate, supported by artistic devices as resistance strategies and construction of dissident subjectivities, and I illustrate this narrative bringing the story of Branca and José Pássaro Volante, characters of Lídia Jorge's work O dia dos prodígios (The day of the prodigies).

Homofobia familiar: abrindo o armário entre quatro paredes

Sexuality device authorizes families to become the guardians of its members’ sexuality, ensuring the exclusion of any kind of dissidence from heteronormativity by means of reinforcement of homophobia. This paper presents the analyses of female participants who are dissident of heteronormativity. They were accessed through snow-ball technique and were interviewed. After transcribing their interviews, the researcher produced narratives of their lives with were corroborated with the participants. Data were analyzed from a poststructuralist perspective. By then, we privileged the study of the manifestation of homophobia in the family, developing a genealogy of their detractors effects, but also highlighting modes of resistance to it. This locus of manifestation of homophobia, obscured by the intimacy of the private world, is still a fairly discussed topic in national studies and maximizes the damage caused by discrimination in macro social spaces. We pointed out, then, family as an important target of action for public policies which aim the protection of human and civil rights, as well as all kinds of violence and discrimination.

Dissidências existenciais de gênero: resistências e enfrentamentos ao biopoder

This article approaches the questions about the sexes, genders, desires and sexual standardization practices, starting from the appearance of new sexual identities that can be classified as queer – travesty, transsexual and transgender people. Still, we problematize how the manners of established forms of subjectivity and the hegemonic institutions marginalize such forms of existences, because of the immense difficulty in the encounter with the stranger, the different and the unusual. With those analyses, we are trying to provide the creation of devices to reduce the intensities of the discrimination, of the stigmatization, of the violence, so frequently lived by the people dissident from the heterosexual gender normative, what was reported about their own lived experiences.
