ELAS SIM! Empoderamento feminino nas instituições de ensino superior no município de João Pessoa/PB

O empoderamento feminino atribui fatores que impulsionam as mulheres a administrarem com maestria a dupla jornada, conciliando a trajetória familiar com os desafios profissionais. Tais atributos são fundamentais para que seja possível contemplar a ascensão feminina em cargos de liderança. Sendo assim, este artigo teve por objetivo identificar os fatores que contribuem para o empoderamento na carreira de mulheres que alcançaram cargos de alta gestão em instituições de ensino superior no município de João Pessoa - PB. A parte empírica do artigo teve como lócus três instituições de ensino superior. Os dados desse estudo foram coletados a partir de entrevistas semiestruturas junto a sete gestoras nas instituições de ensino, que teve como base metodológica os estudos de Malhotra et al. (2002) e Luttrell et al. (2009). Foi utilizado o método qualitativo para obtenção dos resultados da pesquisa. Os resultados apresentados evidenciam cinco fatores dimensionais relacionados ao empoderamento feminino, aos quais, contribuíram para a ascensão profissional das entrevistadas. Os principais achados estão relacionados ao reconhecimento profissional de modo meritocrático, pois a proatividade e empenho destacaram-se como fatores relevantes para coordenar processos decisórios que influem grande impacto nas organizações

Structure and mechanical properties of polyamide 6/Brazilian clay nanocomposites

Recent interest in polymer/organoclays nanocomposites systems is motivated by the possibility of achieving enhanced properties and added functionality at lower clay loading as compared to conventional micron size fillers. By adding montmorillonite clay to polyamide 6 increases the Young modulus, yield strength and also improves barrier properties. In this work, nanocomposites of polyamide 6 with montmorillonite clay were obtained. The clay was chemically modified with three different quaternary ammonium salts such as: Dodigen, Genamin and Cetremide. In this case, a dispersion of Na-MMT was stirred and a salt equivalent to 1:1 of cation exchange capacity (CEC) of Na-MMT was added to the dispersion. The montmorillonite clay (untreated and treated by ammonium salts) and nanocomposites were characterized by X ray diffractions. Also the nanocomposites were characterized by transmission electron microscopy and mechanical properties. The results indicated that all the quaternary ammonium salts were intercalated between the layers of clay, leading to an expansion of the interlayer spacing. The obtained nanocomposites showed better mechanical properties when compared to polyamide 6. The clay acted as reinforcing filler, increasing the rigidity of nanocomposites and decreasing its ductility

The importance of hemovigilance in the transmission of infectious diseases

Background: Hemovigilance is an organized system of surveillance throughout the transfusion chain intended to evaluate information in order to prevent the appearance or recurrence of adverse reactions related to the use of blood products. Objective: The aims of this study were to assess the late reporting of incidents related to possible seroconversion in respect to age, marital status and ethnical background, annual variations in late reporting, the number of reports opened and closed, seroconversion of donors and transfusions of blood products within the window period. Methods: This retrospective, descriptive study used data on blood donations in the blood bank in Uberaba during the period from 2004 to 2011. Some socio-epidemiological characteristics of the donors and serology test results of donors and recipients were analyzed in respect to the late reporting of incidents related to possible seroconversion. The Chi-square test, odds ratio and a regression model were used for statistical analysis. Results: From 2004 to 2011, the blood bank in Uberaba collected 117,857 blood bags, 284 (0.24%) of which were investigated for late reported incidents. The profile of the donors was less than 29 years old, unmarried and non-Whites. Differences in age (p-value < 0.0001), marital status (p-value = 0.0002) and ethnical background (p-value < 0.0001) were found to be statistically significant. There was no statistical difference between men and women (0.24% and 0.23% respectively; p-value = 0.951). The number of late reported incidents increased until 2008 followed by a downward trend until 2011. There were twelve cases of seroconversion in subsequent donations (seven human immunodeficiency virus, four hepatitis B and one hepatitis C) with proven human immunodeficiency virus infection after screening of only one recipient. Conclusion: The twelve cases of seroconversion in donors with subsequent infection proven in one recipient underscores the importance of this tool to increase transfusion safety

It can be induced during bacterial and viral infections, but its production was never investigated in protozoan infections. American Tegumentary Leishmaniasis (ATL) is caused by Leishmania protozoan leading to cutaneous, nasal or oral lesions. The aim of this study was to evaluate the expression of IL-32 in cutaneous and mucosal lesions as well as in peripheral blood mononuclear cells (PBMC) exposed to Leishmania (Viannia) braziliensis. Methods: IL-32, tumour necrosis factor (TNF) and IL-10 protein expression was evaluated by immunohistochemistry in cutaneous, mucosal lesions and compared to healthy specimens. The isoforms of IL-32α, β, δ, γ mRNA, TNF mRNA and IL-10 mRNA were assessed by qPCR in tissue biopsies of lesions and healthy skin and mucosa. In addition, PBMC from healthy donors were cultured with amastigotes of L. (V.) braziliensis. In lesions, the parasite subgenus was identified by PCR-RFLP. Results: We showed that the mRNA expression of IL-32, in particular IL-32γ was similarly up-regulated in lesions of cutaneous (CL) or mucosal (ML) leishmaniasis patients. IL-32 protein was produced by epithelial, endothelial, mononuclear cells and giant cells. The IL-32 protein expression was associated with TNF in ML but not in CL. IL-32 was not associated with IL-10 in both CL and ML. Expression of TNF mRNA was higher in ML than in CL lesions, however levels of IL-10 mRNA were similar in both clinical forms. In all lesions in which the parasite was detected, L. (Viannia) subgenus was identified. Interestingly, L. (V.) braziliensis induced only IL-32γ mRNA expression in PBMC from healthy individuals. Conclusions: These data suggest that IL-32 plays a major role in the inflammatory process caused by L. (Viannia) sp or that IL-32 is crucial for controlling the L. (Viannia) sp infection
