1. Methylation of p16 ink4a promoter is independent of human papillomavirus DNA physical state: a comparison between cervical pre-neoplastic and neoplastic samples
BACKGROUND Epigenetic modifications in host cells, like p16 ink4a methylation, have been considered as putative complementary mechanisms for cancer development. Because only a small proportion of infected women develop cervical cancer, other factors might be involved in carcinogenesis, either independently or in association with high-risk human papillomavir

2. Influência da membrana de colágeno suíno purificado na integração tecidual de telas de polipropileno implantadas em ratas / Purified porcine collagen membrane modulates integration of polypropylene mesh implant in rat model
Introdução: O aumento da expectativa de vida elevou o risco da necessidade de cirurgia para o tratamento dos prolapsos de órgãos pélvicos (PO) em mulheres, principalmente no período pós-menopausa. Os distúrbios ocasionados pelos POP afetam a qualidade de vida, ao estabelecer alterações na sexualidade, função urinaria e intestinal. Neste cenário,

3. Integração econômica regional e investimento estrangeiro direto na América Latina: os casos do Brasil e Argentina / Regional Economic Integration and Foreign Direct Investment in Latin America: the cases of Brazil and Argentina
Given the significant increase in flows of foreign direct investment and the proliferation of economic integration agreements from 90 years, this paper aims to analyze the formation of MERCOSUR has helped attract foreign direct investment to Brazil and Argentina. For this discussion, the work is composed of four parts, besides the introduction and conclusion

4. Construção e caracterização de linhagens de Salmonella enterica mutantes nos genes de IHF (Integral Host Factor) / Construction and characterization of Salmonella enterica strains mutants in IHF (Integral Host Factor) genes
O gênero Salmonella spp é formado por bacilos gram-negativos, que podem ser divididos em 3 espécies: S. enterica, S. bongori e S. subterranea. A maioria das sorovariedades patogênicas para o homem está incluída no subgrupo I da espécie S. enterica. A infecção por S. enterica inicia-se com a ingestão de água ou alimentos contaminados. Estes microrg

5. ANÁLISE DE DIFERENTES PROCESSOS SUBTRATIVOS UTILIZADOS NO TRATAMENTO DA SUPERFÍCIE DE IMPLANTES ODONTOLÓGICOS DE TITÂNIO CP / EXPERIMENTAL STUDIES OF DIFFERENT SURFACE TREATMENTS APPLIED TO TITANIUM DENTAL IMPLANTS
Titanium alloys are widely used in dental implants in virtue of clinical evidences of the excellent biocompatibility performance shown by this alloys. However, there are still a number of unanswered questions regarding the ideal physicochemical properties of titanium surfaces used in dental implants aiming at an appropriate integration with the bone. Further

6. A novel host factor for integration of mycobacteriophage L5
Bacterial integration host factors (IHFs) play central roles in the cellular processes of recombination, DNA replication, transcription, and bacterial pathogenesis. We describe here a novel mycobacterial IHF (mIHF) of Mycobacterium smegmatis and Mycobacterium tuberculosis that stimulates integration of mycobacteriophage L5. mIHF is the product of a sing

7. Modulation of Activity of Moloney Murine Leukemia Virus Preintegration Complexes by Host Factors In Vitro
We have explored the requirements for host proteins in the integration of Moloney murine leukemia virus (MoMuLV) cDNA in vitro. Following infection, it is possible to lyse cells and obtain preintegration complexes (PICs) capable of integrating the MoMuLV cDNA into an added target DNA in vitro (intermolecular integration). PICs can be stripped of required pro

8. Integrase-Specific Enhancement and Suppression of Retroviral DNA Integration by Compacted Chromatin Structure In Vitro
Integration of viral DNA into the host chromosome is an obligatory step in retroviral replication and is dependent on the activity of the viral enzyme integrase. To examine the influence of chromatin structure on retroviral DNA integration in vitro, we used a model target comprising a 13-nucleosome extended array that includes binding sites for specific tran

9. Development of an In Vitro Integration Assay for the Bacteroides Conjugative Transposon CTnDOT
Integrated self-transmissible elements called conjugative transposons (CTns) are responsible for the transfer of antibiotic resistance genes in many different species of bacteria. One of the best characterized of these newly recognized elements is the Bacteroides CTn, CTnDOT. CTnDOT is thought to have a circular transfer intermediate that transfers to and in

10. The barrier-to-autointegration protein is a host factor for HIV type 1 integration
In vivo, retroviral integration is mediated by a large nucleoprotein complex, termed the preintegration complex (PIC). PICs isolated from infected cells display in vitro integration activity. Here, we analyze the roles of different host cell factors in the structure and function of HIV type 1 (HIV-1) PICs. PICs purified by size exclusion after treatment with

12. A previously unidentified host protein protects retroviral DNA from autointegration
Integration of a DNA copy of the viral genome into a host chromosome is an essential step in the retrovirus life cycle. The machinery that carries out the integration reaction is a nucleoprotein complex derived from the core of the infecting virion. To successfully integrate into host DNA, the viral DNA within this complex must avoid self-destructive integra
