13. High genetic differentiation of grapevine rootstock varieties determined by molecular markers and artificial neural networks
ABSTRACT. The genetic differentiation of grapevine rootstock varieties was inferred by the Artificial Neural Network approach based on the Self-Organizing Map algorithm. A combination of RAPD and SSR molecular markers, yielding polymorphic informative loci, was used to determine the genetic characterization among the rootstock varieties 420-A, Schwarzmann, I

15. Molecular identification of three species of Oncideres (Coleoptera: Cerambycidae) using RAPD markers
Abstract: Twig girdlers have a short adult life and a long larval stage (up to one year in some species). This fact, together with lack of morphological traits to identify the species from the larval stage, poses obstacles for the taxonomic identification and characterization of the many twig girdlers found in the wild. To solve this matter, Random Amplified

17. GENETIC DIVERSITY AMONG AND WITHIN BRAVE BEAN (Capparis flexuosa L.) POPULATIONS ASSESSED USING RAPD MARKERS
RESUMO O feijão-bravo (Capparis flexuosa) é uma espécie nativa da Caatinga e é utilizada como forrageira, principalmente na estação seca onde parte das espécies vegetais perdem suas folhas. Objetivou-se estudar a diversidade genética dentro e entre populações de feijão-bravo usando marcadores RAPD. O estudo foi realizado no Laboratório de Biotecn

18. Genotyping of Leptospira interrogans isolates from Mexican patients
ABSTRACT The aim of this study was genotypically characterize Leptospira sp. clinical isolates from Mexico which were previously identified as Leptospira interrogans serovar Pomona (POM) by phenotypic methods. The Random Amplified Polymorphic DNA (RAPD) method was used for DNA amplification with five oligonucleotides. A dendrogram was constructed using the U

19. Rastreamento de BSA e marcadores moleculares para mutante tolerante ao estresse salino de Petunia obtido em cultura in vitro
RESUMO: Neste estudo, realizamos BSA para identificar marcadores genéticos ligados à tolerância ao sal. Testamos a diversidade genética entre quatro amostras de DNA volumoso de clones mutantes induzidos por EMS, e uma amostra de DNA volumoso de clone não mutado de Petunia para tolerância a sal em culturas de calos in vitro usando marcadores RAPD e ISSR

20. Assesment of the Genotoxic Effect of the Diazinon on Root Cells of Allium cepa (L.)
ABSTRACT Organophosphorous pesticides (OPs) posses a great potential of acute toxicity for exposed animals and men. To evaluate the toxic potential of the organophosphate diazinon on root meristematic cells of Allium cepa L., was created two groups: In group 1 (control group), was not given any chemical. In group 2 (diazinon-treatment group), different doses

21. Alterations in Biomarkers Associated with Sterility in Pectinophora gossypiella (Saunders) Induced by Gamma Irradiation
ABSTRACT Nowadays, radiation technology is widely used to produce changes in Biosystems. The goal of this work is to determine the variation induced male Pectinophora gossypiella in gamma-irradiated as pupae using 50Gy and 150Gy. Comparing elements composition and DNA (using RAPD-PCR) between substerile 50Gy and the sterile dose 150Gy in P. gossypiella showe

22. Clonal relation and antimicrobial resistance pattern of extended-spectrum β-lactamase- and AmpC β-lactamase-producing Enterobacter spp. isolated from different clinical samples in Tehran, Iran
Abstract INTRODUCTION: Here, we determined the genes encoding antibiotic resistance enzymes and virulence factors and evaluated the genetic relationship between Enterobacter spp. isolated from different clinical samples. METHODS: A total of 57 clinical isolates of Enterobacter spp. were tested for the production of extended-spectrum β-lactamases (ESBLs)

24. Identification and antifungal susceptibility of Candida species isolated from the urine of patients in a university hospital in Brazil
ABSTRACT The aim of this study was to identify Candida spp. isolated from candiduria episodes at a tertiary hospital in the Midwest region of Brazil, and to determine their susceptibility profiles to antifungal compounds. From May 2011 to April 2012, Candida spp. isolated from 106 adult patients with candiduria admitted to the University Hospital of the Fede
