We describe the critical behavior of the Anderson-like transition predicted to occur in the 2D tight-binding model with isotropic scale-free long-range correlated disorder characterized by a power-law spectral density. We explore the scale invariance of the participation function relative fluctuation at the critical point to locate the mobility edge as a function of the power-law spectral density exponent α2D. The states near the band center, which exhibit power-law localization for uncorrelated disorder, become delocalized for α2D>2. In addition, we consider the finite-size scaling hypothesis to estimate the correlation length critical exponent. We find that the critical exponent ν depends on α2D, thus indicating that correlations in the disorder distribution are indeed relevant in this regime, in agreement with the extended Harris criterion.

To identify the incidence of human papillomavirus (HPV) with the presence of other microorganisms. This is a cross-sectional study composed of 128 women who were attended in the basic health units, between 2014 and 2018, to perform the Pap smear. The presence of papillomavirus was investigated using conventional PCR with primers MY09/11 and GP5 +/6+ (echo and endocervix cells) and the smear bacterioscopy of vaginal secretions was performed to identify the microorganisms. Statistical was performed using the square test, including a risk ratio or 95% confidence interval. HPV infection was identified in 48.4% (n = 62) women. Corynebacterium sp (39.8%) was the most prevalent microorganism, followed by Escherichia coli (21.1%), Staphylococcus aureus (14.0%), Gardnerella vaginalis (13.2%) and Candida albicans (7%), respectively. According to statistical analysis or HPV and the group of potentially pathogenic microorganisms had a significant association p <0.02. Corynebacterium sp showed an effective protection (0.356 [0.170-0.744] <0.05) in relation to sociodemographic, gynecological and obstetric factors. Only vaginal discharge and pH had p <0.05 when comparing the presence of infection. The other variables showed no statistical differences. This study revealed an association between the presence of pathogenic microorganisms with HPV virus infection, confirming a need for a better understanding of the female genitals’ microbiota. Thus, research involving the vaginal infectious agents, methods of protection and rapid diagnosis to contribute to the reduction of the number of lesions in the cervix and cervical cancer are needed.

Objetivo: realizar uma revisão integrativa da literatura sobre polimorfismos associados com o câncer de bexiga em meio à intoxicação por agrotóxicos. Método: trata-se de uma revisão integrativa, na qual a busca foi realizada utilizando os descritores polymorphisms, agrochemical, herbicide, pesticide, "bladdercancer", "bladderneoplasm", case-control, "case-controlstudy" nas bases de dados: PubMed, Web of Science, Science Direct e Periódico da Capes. Resultados: o estudo localizou 56 documentos, destes, cinquenta e um foram excluídos por não atenderem aos critérios de elegibilidade, e cinco foram incluídos. A maioria destes estudos não mostrou claramente quais polimorfismos são associados com o câncer de bexiga em meio a exposição a agrotóxicos. Conclusão: Foi possível identificar os polimorfismos AS3MT rs11191438, AS3MT rs10748835 e AS3MT rs1046778 associados com o câncer de bexiga, mas os dados foram inconclusivos para a associação à intoxicação por agrotóxicos.
