    Focusing on a critical theory of the knowledge organization (KO), unfolding the studies like those of Martínez-Ávila, Daniel; Semidao, R .; Ferreira, M. (2016) and Olson (2006), the empirical plan of the research is related to the comments produced after the murder of the deputy of Rio de Janeiro City, Marielle Franco, and the driver Anderson Gomes, in March 2018. We have tried to deepen the studies already carried out (Saldanha, Silva, Lima, Garcês, Romeiro, 2018) in the territory of the meta-discursive corpus produced on the basis of what we have been working under the notion of ordinary organization of socially oppressed knowledge about crime, with a focus on Marielle's female political presence. The research dialogues with the questioning of the power of language and the role of the KO in the contemporary production of the vocabularies of evil. Like Capurro (2019), the approach to the thinking of the philosopher Hannah Arendt (1999, 2007), within the framework of the reflection on the evil in expansion in the society and its forms (in our case, structurally originating from and oriented to the language) of trivialization. For this current stage of research, we discuss the condition of citizenship in the global digital world and the dilemma (also essentially linguistic) of the algorithms, as well as the power of a robotic ethos that interests critically the KO. The condition of the racist and ethical algorithms of robots is debated from the Ertzcheid (2017) thinking, pointing out online search engines present racist stereotypes and hate speech. From the context of the murder, we direct our scientific look at the discursive production on Marielle Franco established in electronic publications after the first news of the crime. The course allowed us to demonstrate the critical panorama of folk approaches and the need to build a look based on the constant revision of the ethical positions of language construction and its reproduction in and for the web. The corpus demonstrated the role of robots in the massive reproduction of misinformation. With this reflection, the development of critical theories in KO, falls here on the dilemma of a global digital citizenship and the evil represented by algorithms, machines of reproduction of the paths that distance us from the minimum conditions of human dignity. The Marielle case is emblematic in this sense, given that the cruelty involved in the whole process is not enough, it is perceived that its murder is long and continuous, influenced by a robotics of evil and by the continuous algorithmic manipulation. The case reveals precisely the tragic dynamics of the modes of production, organization, representation of knowledge on the web and the emergency role of the constitution of critical theories of knowledge organization

    Prognostic Value of DNA and mRNA E6/E7 of Human Papillomavirus in the Evolution of Cervical Intraepithelial Neoplasia Grade 2

    Objective This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). Methods This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. Results Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status ( P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status ( P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. Conclusions The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution

    Haptophyta

    Haptophyta are predominantly planktonic and phototrophic organisms that have their main distribution in marine environments worldwide. They are a major component of the microbial ecosystem, some form massive blooms and some are toxic. Haptophytes are significant players in the global carbonate cycle through photosynthesis and calcification. They are characterized by the haptonema, a third appendage used for attachment and food handling, two similar flagella, two golden-brown chloroplasts, and organic body scales that serve in species identification. Coccolithophores have calcified scales termed coccoliths. Phylogenetically Haptophyta form a well-defined group and are divided into two classes Pavlovophyceae and Coccolithophyceae (Prymnesiophyceae). Currently, about 330 species are described. Environmental DNA sequencing shows high haptophyte diversity in the marine pico- and nanoplankton, of which many likely represent novel species and lineages. Haptophyte diversity is believed to have peaked in the past and their presence is documented in the fossil record back to the Triassic, approximately 225 million years ago. Some biomolecules of haptophyte origin are extraordinarily resistant to decay and are thus used by geologists as sedimentary proxies of past climatic conditions
