13. Genetic variability in G2 and F2 region between biological clones of human respiratory syncytial virus with or without host immune selection pressure
Human respiratory syncytial virus (HRSV) is an important respiratory pathogens among children between zero-five years old. Host immunity and viral genetic variability are important factors that can make vaccine production difficult. In this work, differences between biological clones of HRSV were detected in clinical samples in the absence and presence of se

14. Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert
Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet) on the shrub Tecoma fulva fulva (Cav.)

15. Biological traits and Life table parameters A and B biotype of Bemisia tabaci (Genn.) on cotton and rapeseed
The aim of this work was to construct life table of Bemisia tabaci (Gen.) A and B (silverleaf whitefly B. argentifolii Bellows and Perring) biotype (Hem.: Aleyrodidae) on two host plants; cotton, (Gossypium hirsutum L.) and rapeseed, (Brassica napus L.). Experiments were conducted in a growth chamber under 24 ± 2ºC, 55±3% RH and 16:8 (L:D) h photoperiod o

16. Analysis of 16S rRNA and mxaF genes reveling insights into Methylobacterium niche-specific plant association
The genus Methylobacterium comprises pink-pigmented facultative methylotrophic (PPFM) bacteria, known to be an important plant-associated bacterial group. Species of this group, described as plant-nodulating, have the dual capacity of producing cytokinin and enzymes, such as pectinase and cellulase, involved in systemic resistance induction and nitrogen fixa

17. Reproductive behaviours and host plant selection mediated by semiochemicals in Neoleucinodes elegantalis (Lepidoptera: Crambidae) / Comportamento reprodutivo e seleção de hospedeiro mediada por semioquímicos em Neoleucinodes elegantalis (Lepidoptera: Crambidae)
The searching behaviour in insects is important to acquire food, meeting mates, oviposition sites location and protect the insects against predators. Thus, the majority of herbivorous insects select their host plant and, in particular, the plants part, which it will feed and oviposit on, using, among other tools, host plants semiochemicals. This paper aims:

18. Influência dos polimofismos de nucleotídeo único (SNPs) da APOBEC3G na dinâmica populacional da infecção pelo HIV-1 / Influence of single nucleotide polymorphisms of APOBEC3G in the population dynamic in the HIV-1 infection
APOBEC3G (A3G) has been described as a cellular factor that inhibits replication of HIV-1. During reverse transcription, A3G promotes deamination of cytidine to uracil in the minus strand viral DNA, inducing hypermutation of guanines to adenines in plus strand DNA. The HIV-1 counters this effect by the activity of the viral protein Vif, which counteracts A3G

19. 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

20. Identification of Schistosoma mansoni candidate antigens for diagnosis of schistosomiasis
The development of a more sensitive diagnostic test for schistosomiasis is needed to overcome the limitations of the use of stool examination in low endemic areas. Using parasite antigens in enzyme linked immunosorbent assay is a promising strategy, however a more rational selection of parasite antigens is necessary. In this study we performed in silico anal

21. Clinical applications of immunoglobulin: update
Human immunoglobulin is the most used blood product in the clinical practice. Immunoglobulin applications have increased quickly since the elucidation of its immunomodulatory and antiinflammatory properties which turned this blood product into a precious tool in the treatment of numerous diseases that present with humoral immune deficiency or that cause immu

22. Genetic variability and natural selection at the ligand domain of the Duffy binding protein in Brazilian Plasmodium vivax populations
Background. Plasmodium vivax malaria is a major public health challenge in Latin America, Asia and Oceania, with 130-435 million clinical cases per year worldwide. Invasion of host blood cells by P. vivax mainly depends on a type I membrane protein called Duffy binding protein (PvDBP). The erythrocyte-binding motif of PvDBP is a 170 amino-acid stretch locate

24. Seletividade alimentar e influencia da idade da folha de Eucalyptus spp. para Thyrinteina arnobia (Lepidoptera: Geometridae).
Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae) e considerada uma das mais serias pragas do eucalipto no Brasil. Este trabalho foi realizado com o objetivo de estudar a preferencia alimentar de T. arnobia em seis especies de eucalipto e a influencia da idade foliar sobre a selecao hospedeira, utilizando-se folhas jovens e velhas de Eucalyptus gr
