13. AvaliaÃÃo de aberraÃÃes cromossÃmicas em bovinos (Bos taurus taurus) infectados pelo papilomavÃrus bovino
Bovine papillomavirus (BPV) is represented by 10 papillomavirus subtypes, epiteliotropic or mucosotropic, which are transmitted among bovines through contaminated blood and ephitelial contact. This virus may be in a latent form on host lymphocytes, triggering chromosomal instabilities. In this context, this study aimed to evaluate chromosomal aberrations whi

17. Assets Pricing in the Brazilian Stock market: CAPM and variants application. / PrecificaÃÃo de ativos com risco no mercado acionÃrio brasileiro: aplicaÃÃo do modelo CAPM e variantes.
The assets pricing models assist in the correct evaluation of the investments, as well as, to comprehend the relationship between the assets expected return and its risk. The Capital Asset Pricing Model (CAPM) and the Downside Capital Asset Pricing Model (D-CAPM), in their conditional and static versions, were tested in this study with time and cross-section

18. Synthesis and Structural Analysis of new Coordination Polymer and molecular compounds of Phosphinatos Metals. / SÍNTESE E ANÁLISE ESTRUTURAL DE NOVOS POLÍMEROS DE COORDENAÇÃO E COMPOSTOS MOLECULARES DE FOSFINATOS METÁLICOS
In this work, the structures of coordination polymers and molecular compounds Cu(II), Hg(II), Pb(II) and Cd(II) with phenylphosphinate or diphenylphosphinate ligands were determined and are discussed. The reaction of phenylphosphinic or diphenylphosphinic acid with copper(II) acetate hydrate produces respectively aquaphenylphosphinate copper(II) or quadiphen

19. Cytogenetic analysis and chromosomal characteristics of the polymorphic 18S rDNA in the fish Prochilodus lineatus (Characiformes, Prochilodontidae)
We used differential staining techniques (BSG, GTG, AgNO3, DAPI and CMA3 banding) and fluorescent in situ hybridization (FISH) with 5S and 18S probes to investigated the karyotypic and cytogenetic chracteristics of Prochilodus lineatus specimens from a population in Vila Velha state park (Parque Estadual de Vila Velha, Ponta Grossa, Paraná state, southern B

20. Dominância fiscal ou dominância monetária no Brasil?: uma análise de causalidade
Brazils inflation targeting regime, which requires a floating exchange rate regime, coupled with high primary fiscal surpluses, helped absorb the external and domestic shocks that hit the economy in post-Real Plan period, maintaining inflation under control. However, a number of authors, such as Blanchard, Tanner e Ramos, and others advocate the predominance

21. Preference shifts, structural breaks and the domestic demand for Chilean wine
Este artigo investiga possíveis mudanças nas preferências dos consumidores de vinho por meio da estimação de uma função da demanda que permite a ruptura estrutural e a mudança do regime no vetor da co-integração do mesmo. Nossos resultados mostram uma elevada elasticidade - preço e uma maior substituição entre o vinho e a cerveja a partir de 198

22. Cytogenetic effect of Sm-153-EDTMP in peripheral lymphocytes of patients with metastaic cancer / "Efeito Citogenético do 153Sm-EDTMP em Linfócitos Periféricos de Pacientes com Câncer Metastático"
The 153Sm-EDTMP is a radiopharmaceutical used in nuclear medicine with promising results for the relief of metastatic pain. Therefore, there are few knowledge about the effects of 153Sm-EDTMP at cellular level. The present study was conducted with the aim of evaluating the cytogenetic effects of 153Sm-EDTMP in peripheral lymphocytes from patients with bone m

23. Developmentally programmed DNA deletion in Tetrahymena thermophila by a transposition-like reaction pathway.
We provide a molecular description of key intermediates in the deletion of two internal eliminated sequences (IES elements), the M and R regions, during macronuclear development in Tetrahymena thermophila. Using a variety of PCR-based methods in vivo, double-strand breaks are detected that are generated by hydrolytic cleavage and correspond closely to the ob

24. Chromosomal aberrations in infective hepatitis
Structural chromosomal aberrations, in the form of breaks, were found in a significantly higher proportion of bone marrow cells in patients with infective hepatitis than in controls. These anomalies were observed during the first and third weeks after the onset of jaundice but had subsided by the sixth week.
