1. The role of gyrA and parC mutations in fluoroquinolones-resistant Pseudomonas aeruginosa isolates from Iran
Abstract The aim of this study was to examine mutations in the quinolone-resistance-determining region (QRDR) of gyrA and parC genes in Pseudomonas aeruginosa isolates. A total of 100 clinical P. aeruginosa isolates were collected from different university-affiliated hospitals in Tabriz, Iran. Minimum inhibitory concentrations (MICs) of ciprofloxacin and lev

2. Transgenic Expression and Identification of Recombinant Human Proinsulin in Peanut
The increased incidence of diabetes, coupled with the introduction of alternative insulin delivery methods that rely on higher doses, is expected to result in a substantial escalation in the future demand for affordable insulin. Plant-based systems offer a safe and economical method for producing pharmaceutical proteins. We used peanut (Arachis hypogaea L.)

3. Molecular findings from influenza A(H1N1)pdm09 detected in patients from a Brazilian equatorial region during the pandemic period
After the World Health Organization officially declared the end of the first pandemic of the XXI century in August 2010, the influenza A(H1N1)pdm09 virus has been disseminated in the human population. In spite of its sustained circulation, very little on phylogenetic data or oseltamivir (OST) resistance is available for the virus in equatorial regions of Sou

4. First report of recombination in Potato yellow vein virus (PYVV) in Colombia
Potato yellow vein virus (PYVV) is currently one of the most important viruses that infects potatoes in Colombia and other Andean countries, causing losses in the production of tubers ranging from 25% to 50%. This study analyzed the genetic variability of different viral isolates collected in the department of Nariño, Colombia, through bioinformatics analys

5. Estudo filogenético do gene apxIA de Actinobacillus pleuropneumoniae sorotipo 5 isolados no Brasil / Phylogenetic analysis of the apxIA gene of Actinobacillus pleuropneumoniae, serotype 5, isolated in Brazil
The toxins produced by Actinobacillus pleuropneumoniae (App) are recognized as major virulence factors found in this pathogen. Apx toxin I has strong hemolytic and cytotoxic activity, and this toxin has a high cytotoxic activity against pulmonary macrophages and neutrophils in swine. This exotoxin is produced by different serotypes, including the serotypes 1

6. Identificação molecular de bactérias ácido láticas isoladas de leite cru e queijo, e pesquisa de genes de bacteriocinas / Molecular identification of lactic acid bacteria isolated from raw milk and cheese, and detection of bacteriocin genes
Considering the importance of the lactic acid bacteria (LAB) as biopreservatives, and their inhibitory potencial against pathogens and spoilage microrganisms, the aim of this study was identify using molecular methodologies LAB isolates obtained from raw milk and soft cheese, and to conduct a detailed study about the presence of bacteriocin codifying genes.

7. Molecular and phylogenetic analysis of the partial tams1 gene sequence of a vaccine strain of Theileria annulata
The polypeptide Tams1 is an immunodominant major merozoite piroplasm surface antigen of the protozoan parasite Theileria annulata and is highly variable. In this study, the partial nucleotide (nt) sequence of the Tams1 (522 nt) gene of Iranian vaccine strain (Vaccine-ir68) recovered from an outbreak of disease in Iran was determined and compared with the cor

8. Variability of the conserved V3 loop tip motif in HIV-1 subtype B isolates collected from Brazilian and French patients
The diversity of the V3 loop tip motif sequences of HIV-1 subtype B was analyzed in patients from Botucatu (Brazil) and Montpellier (France). Overall, 37 tetrameric tip motifs were identified, 28 and 17 of them being recognized in Brazilian and French patients, respectively. The GPGR (P) motif was predominant in French but not in Brazilian patients (53.5% vs

9. Novel sequence variations in LAMA2 and SGCG genes modulating cis-acting regulatory elements and RNA secondary structure
In this study, we detected new sequence variations in LAMA2 and SGCG genes in 5 ethnic populations, and analysed their effect on enhancer composition and mRNA structure. PCR amplification and DNA sequencing were performed and followed by bioinformatics analyses using ESEfinder as well as MFOLD software. We found 3 novel sequence variations in the LAMA2 (c.31

10. Patterns of molecular evolution in pathogenesis-related proteins
The genes encoding 13 classes of pathogenesis-related (PR) proteins were examined for positive selection using maximum-likelihood (ML) models of codon substitution. The study involved 194 sequences from 54 species belonging to 37 genera. Although the sizes of the sequences examined varied from 237 bp for PR12 to 1,110 bp for PR7, most classes (9 out of 13) c

11. Estudo epidemiológico da infecção por herpesvírus 8 humano (HHV-8) em população indígena da Amazônia brasileira / Epidemiological study of Human herpesvirus 8 infection (HHV-8) in the Amerindian population from Brazilian Amazon
The human herpesvirus 8 (HHV-8) is endemic in Africa and Amerindian populations from Amazon region. The infection in those populations occurs during childhood and, in Africa, involves a close contact in intrafamilial environment. Several studies confirm the geographical distribution of different subtypes of HHV-8, and the subtype E is typical of the Amerindi

12. Evaluation of parotid and submandibular salivary glands through magnetic resonance and clinical-laboratorial correlations in cronic form Chagas disease bearers / Avaliação das glândulas parótidas e submandibulares por ressonância magnética e correlação clínico-laboratorial em pacientes portadores das formas indeterminada e digestiva da doença de Chagas
INTRODUCTION: Chagas disease is the most important endemic parasitosis in Latin America. The salivary glands onsets for this disease have been poorly studied. For MR (magnetic resonance) sialography has a better sensibility and specificity when compared to different methods and for not being invasive, it is used to identify glandular alterations in patients
