Patologias em fachadas: análises de casos na Universidade Federal do Pará

O sistema de revestimento externo da edificação funciona como camada de proteção e contribui para o bom aspecto da mesma. A fachada está sujeita à ação de agentes de degradação por ser uma das zonas mais expostas do edifício, com a presença de patologia tornando-se responsável por elevados custos de reparos. A pesquisa propõe, como objetivo geral, avaliar patologias que afetem fachadas de edificações de ensino superior da Universidade Federal do Pará, norteada por uma base teórica (revisão bibliográfica) responsável pelas primeiras informações sobre o assunto. Para tal, como metodologia da pesquisa, buscou-se primeiramente realizar levantamento físico de fachadas de 30 edificações na UFPA, identificando em fichas cadastrais os principais mecanismos de degradação. Em seguida, após quantificar/qualificar as anomalias presentes na amostra e apontar a edificação mais crítica com seus principais danos e respectivas causas, listou-se, para esta, medidas básicas de intervenção, visando resolver de modo eficiente o problema decorrente, propondo-se um documento que funcione como suporte técnico para inspeção de fachadas em geral. Utilizou-se também de ensaios para caracterizar amostras, de modo a comprovar as origens daqueles danos em que à primeira vista não se conseguiu identificar a causa. Os resultados permitiram concluir que as edificações analisadas apresentam danos patológicos de diferentes natureza e grau de complexidade, indo desde os mais complexos que necessitaram de ensaios específicos para descobrir sua origem; até os mais simples, que com manutençao programada podem ser eliminado. Conclui-se que grande parte dos danos acontecem por negligência humana, mas que, mesmo dando ênfase na qualidade de execução em fachadas, não há como descartar a hipótese de falhas nem ignorar que o tempo de uso e as ações de fatores externos levam à degradação natural da edificação. Portanto, de modo a evitar o aparecimento precoce de patologias em fachadas, elevando seu tempo de vida útil e reduzindo custos extras, sugere-se, procedimentos de execução baseados em normas técnicas com fiscalização dos mesmos, obedecendo critérios de projeto e apresentando programas de vistorias periódicas para que medidas preventivas sejam tomadas em tempo hábil.

Metodologia microbiológica convencional e reação em cadeia pela polimerase (PCR) na detecção de Salmonellasp. a partir de caldos de enriquecimento – Tetrathionato e Rappaport-Vassiliadis

The progressive increase in consumption and production of poultry meat in later years comes forth with an increase of the occurrence of foodborne diseases, including salmonellosis. Salmonellosis is caused by the ingestion of contaminated products, mainly by the consumption of poultry meat which processing and preparation for consumption were not effective to eliminate pathogens. Thus, there is a need for the development of faster more sensitive methods of detection of pathogens as a way to ensure the quality of the food offered to consumers. The goal of this essay was to evaluate the effect of enrichment broths on naturally contaminated poultry meat samples. A total of 65 samples was collected, these samples were rinsed with 370 mL of buffered peptone water (BPS) 1% according with the traditional methodology. All of the samples were enriched with both Tetrathionate (TT) and Rappaport-Vassiliadis (RV) and all were analyzed by the convencional identification method and polimerasis chain reaction (PCR). Of the 65 analized samples, 34 (52%) were positive when analized by the conventional method, while 45 (69%) were positive when analized by the PCR. Amongst the 45 positive PCR samples, 44 samples were positive when enriched with TT, while just 32 samples were positive when enriched by RV. Of the 34 positive conventional samples, 29 samples were positive when enriched by TT and 31 were positive when enriched by RV

Melodrama em falso e pedagogia social de Capitu, de Luiz Fernando Carvalho: a adaptação de Dom Casmurro para o audiovisual em três lições

Some esthetical particularities of Luiz Fernando Carvalho’s micro-series reveal, in the nineteenth century Brazil, the capacity of the literary and audiovisual discourse to represent some singularities of the Brazilian social life from the past, as well as pointing to existential problems of the class representative that leads the plot, instigating reflections in the present. The treatment offered to the class struggle by the Machadian narrative and by the Rede Globo’s adaptation, just as the way in which the existential drama is expounded, disclose a kind of reception among readers/viewers which is capable of reviewing the historical past in times that ask for such a revision, even though the television series bets on the non-conventional. Machado presented the tension between representation and truth (as well as between emotion production and reflection) with the transfiguration of the tragic pathos and the mobilization of the patriarchal figure to the melodramatic bias. Although increased by the irony orchestrated by the scenic elements, in the audiovisual version such Machadian solutions would be apt to lose their strength to unmask the social subjects; on the other side, the intensification of the melodrama can make evident what Machado disguised with less obvious narrative intentions.

JAVMA37-43 Anthrax in Swine

Anthrax is not commonly considered so important a menace to swine as it is to other forms of live stock, in which the disease is apt to declare itself with terrifying severity. In comparison with the marked mortality frequently observed in cattle, the tangible losses caused by anthrax in swine seem negligible. As recent as 25 years ago, there still were observers who sincerely doubted the occurrence of the disease in hogs and this opinion found some support in the many reported failures to induce the infection in that animal species by artificial methods.

Development of albendazole sulfoxide-loaded Eudragit microparticles: A potential strategy to improve the drug bioavailability

Albendazole sulfoxide (ABZSO), a broad spectrum anthelmintic drug extensively used in veterinary medicine, exhibits a low and erratic bioavailability due to its poor solubility in biological fluids. The aims of this study were the development, physicochemical characterization, and in vitro release profile evaluation of ABZSO-loaded Eudragit RS PO (R) microparticles (MPs) in order to improve the rate of dissolution and the dissolved percentage of the drug in pH 7.4. MPs were successfully obtained by the emulsification/solvent evaporation method, achieving entrapment efficiency and process yield of about 60% and mean size of 254 nm. The in vitro release profile study showed that dissolution of ABZSO followed a pseudo-second order kinetics and MPs were able to increase significantly (p < 0.05) the rate of dissolution of ABZSO compared to the micronized and non-micronized free drug, what could lead to an improvement in bioavailability and, consequently, in the antiparasitic activity.

Antioxidant treatment protects against matrix metalloproteinase activation and cardiomyocyte injury during acute pulmonary thromboembolism

Increased reactive oxygen species (ROS) promote matrix metalloproteinase (MMP) activities and may underlie cardiomyocyte injury and the degradation of cardiac troponin I (cTI) during acute pulmonary thromboembolism (APT). We examined whether pretreatment or therapy with tempol (a ROS scavenger) prevents MMP activation and cardiomyocyte injury of APT. Anesthetized sheep received tempol infusion (1.0 mg kg(-1) min(-1), i.v.) or saline starting 30 min before or 30 min after APT (autologous blood clots). Control animals received saline. Hemodynamic measurements were performed. MMPs were studied in the right ventricle (RV) by gelatin zymography, fluorimetric activity assay, and in situ zymography. The ROS levels were determined in the RV and cTI were measured in serum samples. APT increased the pulmonary arterial pressure and pulmonary vascular resistance by 146 and 164 %, respectively. Pretreatment or therapy with tempol attenuated these increases. While APT increased RV + dP/dt (max), tempol infusions had no effects. APT increased RV MMP-9 (but not MMP-2) levels. In line with these findings, APT increased RV MMP activities, and this finding was confirmed by in situ zymography. APT increased the RV ROS levels and tempol infusion, before or after APT, and blunted APT-induced increases in MMP-9 levels, MMP activities, in situ MMP activities, and ROS levels in the RV. cTI concentrations increased after APT, and tempol attenuated these increases. RV oxidative stress after APT increases the RV MMP activities, leading to the degradation of sarcomeric proteins, including cTI. Antioxidant treatment may prevent MMP activation and protect against cardiomyocyte injury after APT.
