13. Fatores associados á infecção por Toxoplasma gondii em gestantes atendidas nas unidades básicas de saúde do município de Rolândia, Paraná
The aim of this study was to determine the prevalence against IgG and IgM anti-Toxoplasma gondii antibodies in pregnant women attended in Health Basic Unities (UBS) in Rolândia city -Paraná-Brasil, and identify factors associated with infection by T. gondii. The prenatal screening program was implemented in the city in July 2007. 320 pregnant women were ev

14. Surface morphology of spray-dried nanoparticle-coated microparticles designed as an oral drug delivery system
This paper was devoted to studying the influence of coating material (nanocapsules or nanospheres), drug model (diclofenac, acid or salt) and method of preparation on the morphological characteristics of nanoparticle-coated microparticles. The cores of microparticles were obtained by spray drying or evaporation and the coating was applied by spray drying. SE

15. Polymeric coating and pharmacokinetic of chitosan granules containing ddI incorporated in microparticles / Revestimento polimerico e farmacocinetica de granulos gastrorresistentes contendo didanosina incorporada em microparticulas de quitosana
This work studied the production and pharmacokinetic of a new pharmaceutical formulation of the didanosine (ddI) drug ,composed by chitosan granules containing ddI incorporated in microparticles, for oral administration in the AIDS therapy. The advantages of this new pharmaceutical formulation compared to the conventional one are: to assure ddI stability in

16. Estudo epidemiológico da Toxoplasmose em gestantes atendidas na Maternidade Escola Januário Cicco, Natal, Rio Grande do Norte
Congenital Toxoplasmosis results in severe systemic disease. If mother is infected for the first time during gestation, she can infect the fetus causing substantial damage. However, relatively little is known about the seroprevalence and epidemiological and economic factors of Toxoplasmosis infection in pregnancy in the most state in northeastern Brazil and

17. Estudo físico-químico de micropartículas compostas por P(HB-HV) e por blendas de P(HB-HV) e PCL contendo fármacos-modelo lipofílicos ionizáveis / Physico-Chemical Study of Microparticles Composed of P(HB-HV) and P(HB-HV)/PCL Blends Loaded with Ionizable Lipophilic Drug-Models
Micropartículas formadas por blendas de P(HB-HV) com PCL apresentam aumento da porosidade com o aumento do percentual de PCL. Considerando-se a influência de poros na velocidade de liberação de fármacos, bem como a ausência de estudos que correlacionem quantitativamente perfis de liberação e características morfológicas de micropartículas de P(HB-

18. Genetic transformation of Sorghum bicolor (L. Moench) aiming Al+3 tolerance / TransformaÃÃo genÃtica de Sorghum bicolor (L. Moench) visando tolerÃncia ao AlumÃnio.
The genetic transformation has been frequently associated with conventional genetic breeding programs. This technique allows the introduction of exogenous gene(s) into plant genomes, modifying specific characteristics. It can be an important supplementary tool for sorghum conventional breeding programs. However, most of the genetic transformation protocols r

20. Prevalência de toxoplasmose aguda em gestantes, incidência de toxoplasmose congênita e desempenho de testes diagnósticos em toxoplasmose congênita
Introdução: A infecção aguda pelo Toxoplasma gondii em gestantes pode determinar infecção fetal através de passagem transplacentária. As crianças afetadas podem desenvolver coriorretinite e déficit neurológico, na ausência de tratamento adequado. Objetivos: Estimar a prevalência de toxoplasmose aguda em gestantes atendidas na maternidade do Hosp

21. Modeling and simulation of rapid expansion of supercritical solutions
Rapid expansion of supercritical solution (RESS) is a promising technique for microparticle production. The literature points out that the RESS technique can be applied to process a wide range of materials including ceramics, polymers, biopolymers, pharmaceutics, and organic compounds. In order to achieve an adequate understanding of the RESS process, it is

22. Avidity of IgG for rubella: an evaluation of the need for implementation at the Materno-Infantil Presidente Vargas Hospital in Porto Alegre, Rio Grande do Sul, Brazil
Rubella serum assays performed in the laboratory of the Materno-Infantil Presidente Vargas Hospital (HMIPV) from 1998 to 2002 were reviewed to determine if IgG avidity assays should be implemented. IgG was determined using the Enzyme Linked Fluorescent Assay, ELFA, VIDAS® system, bioMérieux or the Microparticle Enzyme Immunoassay, MEIA, Axsym® system, Abb

24. Infecção pelo vírus da hepatite C na população de Londrina e região norte do Paraná: aspectos soroepidemiológicos e moleculares / Hepatitis C virus infection in a population from Londrina, PR, Brazil: serological, epidemiological and molecular aspects
The objective of this work was to evaluate hepatitis C virus (HCV) infection in individuals of Londrina, Paraná State, Brazil, and adjacent areas. Samples of blood donors and individuals infected with Human Immunodeficiency virus (HIV) were analyzed by microparticle enzyme immunoassay (MEIA). Anti-HCV antibody frequency was 0.8% in blood donors, and 20.2% i
