1. Lytic bacteriophages as a potential alternative to control Staphylococcus aureus
Resumo: O objetivo deste trabalho foi caracterizar bacteriófagos autóctones e determinar sua atividade lítica em Staphylococcus aureus. Seis fagos foram isolados de água de lavagem de pisos de estábulos por meio do enriquecimento de cultura com três estirpes de S. aureus. Todos os fagos foram caracterizados pela digestão do DNA com enzimas de restriç

2. DNA hypermethylation of Fgf16 and Tbx22 associated with cleft palate during palatal fusion
Abstract Objective: Cleft palate (CP) is a congenital birth defect caused by the failure of palatal fusion. Little is known about the potential role of DNA methylation in the pathogenesis of CP. This study aimed to explore the potential role of DNA methylation in the mechanism of CP. Methodology: We established an all-trans retinoic acid (ATRA)-induced CP

3. Biomolecular computers with multiple restriction enzymes
Abstract The development of conventional, silicon-based computers has several limitations, including some related to the Heisenberg uncertainty principle and the von Neumann “bottleneck”. Biomolecular computers based on DNA and proteins are largely free of these disadvantages and, along with quantum computers, are reasonable alternatives to their convent

4. Rhizobacterial characterization for quality control of eucalyptus biogrowth promoter products
Abstract Plant growth-promoting rhizobacteria strains from special formulations have been used to optimize eucalyptus cutting production. To undertake quality control for the formulated products, the rhizobacterial strains should be characterized to assess their purity and authentication. In the present study, we characterized nine strains of rhizobacteria,

5. Is Malassezia nana the main species in horses’ ear canal microbiome?
ABSTRACT The objective of this study was to characterize genotypically Malassezia spp. isolated from the external ear canal of healthy horses. Fifty-five horses, 39 (70.9%) males and 16 (29.1%) females, from different breeds and adults were studied. External ear canals were cleaned and a sterile cotton swab was introduced to collect cerumen. A total of 110 s

7. Age-related Changes in DNA Methylation Status of hTERT Gene Promoter of Oral Epithelial Cells
The purpose of this study was to investigate the effect of aging on the DNA methylation status of two genes involved in tumorigenesis (telomerase gene hTERT and DNA repair gene- MLH1) and one in metabolism (methylenetetrahydrofolate reductase gene- MTHFR) in oral epithelial cells. DNA methylation analysis was performed by Methylation Sensitive Restriction En

8. Identification of blood meal sources of Lutzomyia longipalpis using polymerase chain reaction-restriction fragment length polymorphism analysis of the cytochrome B gene
An analysis of the dietary content of haematophagous insects can provide important information about the transmission networks of certain zoonoses. The present study evaluated the potential of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the mitochondrial cytochrome B (cytb) gene to differentiate between vertebrat

9. Differential detection of transposable elements between Saccharum species
Cultivars of sugarcane (Saccharum) are hybrids between species S. officinarum (x = 10, 2n = 8x = 80) and S. spontaneum (x=8,2n=5-16x =40-128). These accessions have 100 to 130 chromosomes, 80-85% of which are derived from S. officinarum, 10-15% from S. spontaneum, and 5-10% are possible recombinants between the two genomes. The aim of this study was to analy

10. Endophytic bacterial diversity in banana 'Prata Anã' (Musa spp.) roots
The genetic diversity of endophytic bacteria in banana 'Prata Anã' roots was characterized. Two hundred and one endophytic bacteria were isolated, 151 of which were classified as Gram-positive and 50 as Gram-negative. No hypersensitivity response was observed in any of the isolates. The rep-PCR technique generated different molecular profiles for each prime

11. An easy and efficient strategy for KEL genotyping in a multiethnic population
BACKGROUND: The Kell blood group system expresses high and low frequency antigens with the most important in relation to transfusion including the antithetic KEL1 and KEL2; KEL3 and KEL4; KEL6 and KEL7 antigens. Kell is a clinically relevant system, as it is highly immunogenic and anti-KEL antibodies are associated with hemolytic transfusion reactions and he

12. Monitoramento temporal e espacial de contaminações bacterianas na produção de bioetanol: caracterização molecular por T-RFLP e detecção quantitativa por qPCRde comunidades formadoras de biofilmes / Temporal and spatial monitoring of bacterial contamination in bioethanol production: a molecular characterization by T-RFLP and quantitative detection by qPCR of community-formers biofilms
Bacterial contamination by Lactobacillus, Bacillus and Leuconostoc and other lactic acid bacteria is one of the main factors that affects the yield in alcoholic fermentation process. Biofilm formation protects the bacteria community and it is a permanent source of contamination. For characterization of these contaminations in (1) biofilms from centrifuge, ta
