14. Characterization of the photosynthetic conditions and pigment profiles of the colour strains of Hypnea musciformis from field-collected and in vitro cultured samples
Hypnea musciformis (Wulfen) JV Lamour. is a species of great economic interest as it produces Κ-carrageenan and has shown biological activities against HIV and HSV viruses. This species displays different colour strains in its natural habitat, which may have implications for the biotechnological potential of the species. The aim of this study was to charact

15. Guerrear, casar, pacificar, curar : o universo da "tradição" e a experiência com o HIV/Aids no distrito de Homoíne, Sul de Moçambique / War, marriage, peacemaking, cure : the universe of tradition and the experience with the HIV/AIDS in the district of Homoíne, Southern Mozambique
Esta tese é resultado de pesquisas etnográficas realizadas no distrito de Homoíne, Província de Inhambane, no Sul de Moçambique. Visando compreender como se dá a experiência da população local com o HIV/Aids num contexto rural, a partir de suas concepções "tradicionais" sobre as doenças e curas, o trabalho investiga os elementos que constituem o

16. Caracterização biológica e molecular de recombinantes naturais de HIV-1. / Biological and molecular characterization of HIV-1 natural recombinants.
Recombination during reverse transcription is an important factor promoting HIV-1 diversity and adaptive change, allowing advantageous mutations arising on different genomes to undergo linkage in the same progeny recombinant genome more frequently than what would be expected under random mutation alone. In Brazil, several recombinant viruses were reported, a

17. Caracterização molecular de recombinantes intersubtipos do vírus da imunodeficiência humana tipo 1(HIV-1) em pacientes provenientes da epidemia do estado de São Paulo. / Molecular characterization of recombinant intersubtipos of human immunodeficiency virus type 1 (HIV-1) in patients from the epidemic in the state of Sao Paulo, Brazil.
The extensive HIV-1 genetic diversity has several implications on the viral adaptive and evolutionary capabilities. This diversity is due to intensive mutational rates derived from error-prone activity of viral reverse transcriptase and RNA genomic instability, generating a highly diverse and heterogeneous viral population named quasispecies. However, even t

18. Simulação Computacional e Análise de um Modelo Fenotípico de Evolução Viral. / Computer Simulation and Analysis of a Phenotypic Model of Viral Evolution
A large amount of viruses of medical importance such as HIV, respiratory syncytial virus, the hepatitis C virus, influenza A (H1N1) and polio virus, has RNA genome. These viruses exhibit extremely high mutational rate, fast replicative kinetics, large population of particles and high genetic diversity. Manifested during the infectious process, these features

19. The impact of the nelfinavir resistance-conferring mutation D30N on the susceptibility of HIV-1 subtype B to other protease inhibitors
The human immunodeficiency virus type 1 (HIV-1) protease mutation D30N is exclusively selected by the protease inhibitor (PI) nelfinavir and confers resistance to this drug. We demonstrate that D30N increases the susceptibility to saquinavir (SQV) and amprenavir in HIV-1 subtype B isolates and that the N88D mutation in a D30N background neutralizes this effe

20. Neuroinfection survey at a neurological ward in a Brazilian tertiary teaching hospital
OBJECTIVES: This study was undertaken to characterize the neuroinfection profile in a tertiary neurological ward. INTRODUCTION: Neuroinfection is a worldwide concern and bacterial meningitis, tetanus and cerebral malaria have been reported as the commonest causes in developing countries. METHODS: From 1999 to 2007, all patients admitted to the Neurology Ward

21. Genotipagem de HPV proveniente de mulheres soropositivas e soronegativas para HIV atendidas no Centro de Referência em DST/AIDS em Vitória - ES
Os papilomavírus humanos (HPV) são vírus epiteliotrópicos que infectam tecido cutâneo ou mucoso e estão relacionados com desenvolvimento de lesões que, no trato genital, variam de verrugas ao câncer cervical invasivo. Estas lesões são causadas por diferentes tipos de HPV, que são classificados em baixo e alto risco conforme sua associação com c�

23. Molecular characterization of viruses associated with gastrointestinal infection in HIV-positive patients
BACKGROUND: Diarrhea is a major cause of morbidity and mortality among HIV-infected patients worldwide. OBJECTIVE: We sought to determine the frequency of viral gastrointestinal infections among Brazilian HIV-infected patients with diarrhea. METHODS: A collection of 90 fecal specimens from HIV-infected individuals with diarrhea, previously tested for the pre

24. HIV subtype, epidemiological and mutational correlations in patients from Paraná, Brazil
OBJECTIVE: Analyze patients with HIV infection from Curitiba, Paraná, their epidemiological characteristics and HIV RAM. METHODS: Patients regularly followed in an ID Clinic had their medical data evaluated and cases of virological failure were analyzed with genotypic report. RESULTS: Patients with complete medical charts were selected (n = 191). Demographi
