Pascal, a justi a e os poderes
Paulo Ferreira da Cunha
Intercambio , 2010,
Abstract: A perfect master of a living style and a persuasive rhetoric, a respected scientist and mathematician, theologian, or at least strong and formidable apologist, Pascal is regarded as one of the greatest minds and of the most beautiful verb in French Thought. However, his philosophical reflections on law, justice and power and the powerful are less known, or boil down to the anecdote. In this article, after having recalled several facets of this figure in European culture, we emphasize its speculative contribution to the law, and highlight more than its timeliness, which is undeniable, the visible commitment of the author with what he thinks may be the Truth. Even in a field proverbially inclined to embarrassment and manipulations like this one of laws and politics.

World Journal of AIDS (WJA) , 2015, DOI: 10.4236/wja.2015.53018
Abstract: Background: Hepcidin is the principal regulator of iron absorption and its tissue distribution. Its correlation with iron homeostasis in individuals infected with human immunodeficiency virus type-1 (HIV-1) treated with different regimens of highly active antiretroviral therapy (HAART) was investigated. Methods: Serum hepcidin levels were determined in 448 volunteers. Of these, 372 were HIV-1-infected individuals, and 93 did not receive HAART (ART-naïve) while 279 received HAART consisting of a non-nucleoside reverse transcriptase inhibitor (NNRTI-based) and protease inhibitors (PI-based); both were used in association with a nucleoside reverse transcriptase inhibitor (NRTI). Seventy-six additional HIV-1 seronegative individuals were enrolled in the study. The following parameters were quantified: hematological parameters, iron biomarkers and markers of infection (CD4+ and CD8+ T-cells), and HIV-1 RNA (viral load). Results: Serum hepcidin, iron and ferritin levels, as well as the marker of infection, CD4+ T-cells, were significantly lower in the ART-naïve group compared with other groups. Additionally, transferrin saturation, iron binding capacity, hemoglobin level and erythrocyte level were not significantly different, and anemia was not observed in the different groups. Conclusions: HIV-1 infection affected serum hepcidin, iron and ferritin levels in the ART-naïve group, and the different HAART regimens restored the levels of hepcidin and iron homeostasis in HIV-1-infected individuals who have undetectable HIV-1 RNA levels.

Abstract: the concern to apply environmental rules within the productive context of any company is actually a reality in the worldwide scene. waste improvement and commercialization in many industrial deals have led organizations to a new ideology about the managing of this material, where the increase of income generated by its recycling has much contributed to the expansion of this practice. scale is a by-product, which arises from oxidation of the steel surface when it is submitted to a thermal gradient or simply to the action of time. in the metallurgical field, it basically derives from the operations of continuous casting and rolling. scale are iron oxides whose disposal at wastes yards must be carried out following the pertinent environmental laws, since they can be classified as dangerous wastes (class i, nbr 10004:2004). however, there are few studies towards its improvement so as to enhance the worth of the by-product in reference. in this context, drying, sieving and briquetting unit operations were employed on the material processing. physical and chemical characterizations enabled investigation of their properties and prospective industrial applications, aiming to adapt the environmental, economical and processing parameters to the companies' requirements.

Abstract: O objetivo deste trabalho foi identificar o comportamento reprodutivo de um rebanho Gir Mocho criado a campo, em regime de cobertura natural, pertencente à Fazenda Tapete Verde, Município de Carmo do Rio Verde, Estado de Goiás. O trabalho mostra o estudo de 488 dados de partos em vacas Gir Mocho, no período de 1973 a 1976. Observou-se que o maior número de nascimento ocorreu de julho a outubro com o pico máximo em agosto. A distribui o dos nascimentos, bem como das fecunda es neste período, assemelham-se aos resultados obtidos por CARNEIRO e Cols., TABARELLI NETO et alii, JOCHLE, HUDDER e McCAMLEY e GUSM O. O menor número de nascimento ocorreu nos meses de novembro e dezembro e deveu-se à retirada dos touros nos meses de janeiro e fevereiro. Observou-se uma maior propor o de machos, também, nos anos de 1973 a 1976, porém, esta propor o foi estatisticamente significativa apenas em 1974. Os resultados de 192 observa es mostraram que a dura o média do intervalo entre partos foi de 16,82 +/- 4,82 meses. The objective of this study was to identify the reproductive behavior of a herd of Polled Gir Cattle put in open pasture, at the Tapete Verde Ranch in Carmo do Rio Verde County in the state of Goiás. Four hundred and eighty-eight (488) items regarding calving in the Polled Gir cows were studied from 1973 to 1976. It was observed that the highest number of births occurred from July to October, with the peak in August. Birth distribution, as well as impregnations during this period, showed results similar to those cited by CARNEIRO and Cols., TABARELLI NETO et alii., JOCHLE, HUDDER and McCAMLEY, and GUSM O. The lowest birth rate occurred during the months of November and December because the bulls were removed from the herd in the months of January. A large percentage of male calves was born in all three years, although the proportion in relation to female calves was statistically significant only in 1974. The results of 192 items observed showed that the medium interval between births was 16.82 +/- 4.82 months.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0078142
Abstract: Approximately 170 million people are chronic carriers of hepatitis C virus (HCV). Patients with chronic hepatitis C are currently treated with pegylated interferon and ribavirin (PEG-IFN/RBV). A genome-wide association with PEG-IFN/RBV treatment response and a single nucleotide polymorphism (rs12979860) has been identified near the interleukin 28B gene that encodes interferon-λ-3. In this paper, we describe an innovative, fast, and low-cost multiplex polymerase chain reaction with confronting two-pair primers that detects the rs12979860 polymorphism. The assay is internally controlled and does not require the use of restriction endonucleases or special equipment. Moreover, the assay decreases costs, being about 40% cheaper than direct sequencing methods.
