1. Dominant yeasts associated to mango (Mangifera indica) and rose apple (Syzygium malaccense) fruit pulps investigated by culture-based methods
Abstract: The biotechnological potential of yeasts associated to different habitats in Colombia has been poorly studied, especially the yeasts associated with different plant structures. Fruit pulps are interesting substrates mainly for the growth of yeast species, that can positively affect the productivity and quality of some bioeconomic species. Therefore

2. Araucaria angustifolia chloroplast genome sequence and its relation to other Araucariaceae
Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific commun

3. Comparison of rRNA-based reverse transcription PCR and rDNA-based PCR for the detection of streptococci in root canal infections
Abstract Objective The rDNA-based method is unable to distinguish between alive and dead cells. Alternatively, bacterial viability can be assessed by molecular methods based on ribosomal RNA (rRNA). Therefore, this study aimed to detect viable streptococci in root canal samples using rRNA-based reverse transcription polymerase chain reaction (RT-PCR), comp

4. Genotyping of Toxoplasma gondii and Sarcocystis spp. in road-killed wild mammals from the Central Western Region of the State of São Paulo, Brazil
Abstract INTRODUCTION: Road-killed wild animals host zoonotic pathogens such as Toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. METHODS This investigation aimed to determine the presence of T. gondii and other apicomplexan parasites in tissue samples of 64 road-killed wild animals, using polymeras

5. Molecular Identification of Trichoderma spp. in Garlic and Onion Fields and In Vitro Antagonism Trials on Sclerotium cepivorum
ABSTRACT Trichoderma species are non-pathogenic microorganisms that protect against fungal diseases and contribute to increased crop yields. However, not all Trichoderma species have the same effects on crop or a pathogen, whereby the characterization and identification of strains at the species level is the first step in the use of a microorganism. The aim

6. PCI-24781 down-regulates EZH2 expression and then promotes glioma apoptosis by suppressing the PIK3K/Akt/mTOR pathway
PCI-24781 is a novel histone deacetylase inhibitor that inhibits tumor proliferation and promotes cell apoptosis. However, it is unclear whether PCI-24781 inhibits Enhancer of Zeste 2 (EZH2) expression in malignant gliomas. In this work, three glioma cell lines were incubated with various concentrations of PCI-24781 (0, 0.25, 0.5, 1, 2.5 and 5 M) and analyze

7. Identification and characterization of rhizospheric microbial diversity by 16S ribosomal RNA gene sequencing
In the present study, samples of rhizosphere and root nodules were collected from different areas of Pakistan to isolate plant growth promoting rhizobacteria. Identification of bacterial isolates was made by 16S rRNA gene sequence analysis and taxonomical confirmation on EzTaxon Server. The identified bacterial strains were belonged to 5 genera i.e. Ensifer,

8. Caracterização da diversidade de fungos filamentosos associados a esponjas marinhas e avaliação da produção de lacase = : Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production / Diversity of filamentous fungi associated with marine sponges and evaluation of laccase production
The ocean represents a promissing habitat in the search for new microorganisms, which may have the ability to produce enzymes of industrial interests different from that produced by their terrestrial counterparts. In this context, two samples of the marine sponge Dragmacidon reticulatum were collected on northern coast of São Paulo State, aiming at the char

9. The study of the organization of the 5S ribosomal gene in populations of Amazonian Engystomops (Anura, Leiuperidae) / Estudo da organização do gene ribossomal 5S em populações de Engystomops da Amazônia (Anura, Leiuperidae)
O gênero Engystomops apresenta ampla distribuição geográfica e constitui um interessante grupo de anuros para estudos cariotípicos. As populações de Engystomops encontradas na Amazônia têm sua identificação taxonômica ainda controversa. Análises genéticas e citogenéticas apoiam hipóteses que sugerem a existência de um complexo de espécies c

10. Potential use of molecular-typing methods for the identification and characterization of salmonella enterica serotypes isolated in the poultry production chain
Salmonella is widespread in nature and can be found in all links of the poultry production chain. Due to its high impact on meat processing, techniques for the rapid detection and reproducible characterization of Salmonella serotypes in foods are needed. The present study investigated the potential of molecular profiling to identify and differentiate 15 Salm

11. Caracterização funcional da proteína Nop8p de Saccharomyces cerevisiae / Functional characterization of the Saccharomyces cerevisiae nucleolar protein Nop8p
A proteína nucleolar Nop8p de levedura foi identificada inicialmente através de sua interação com Nip7p e está envolvida na formação da subunidade ribossomal 60S. A depleção de Nop8p em células de levedura leva à degradação prematura dos rRNAs, porém o mecanismo bioquímico responsável por este fenótipo ainda não é conhecido. Neste trabalho

12. Identificação de um fator do hospedeiro, RPS5A, envolvido na interação com a proteína de movimento (MP) de geminivírus / Identification of movement protein MP-intaracting host facotrs
The movement protein MP from bipartite geminivirus (begomovirus) facilitates the cell-to-cell and long-distance transport of viral DNA in addition to affecting viral pathogenicity. To identify host factors that interact with MP, initially a cDNA library prepared from CaLCuV (Cabbage leaf curl virus)-infected Arabidopsis leaf mRNA was generated in a pEXPAD502
