| Em certas espécies vegetais, a distinção entre variedades pode ser realizada com base em aspectos morfológicos das plantas, o que permite a identificação mesmo quando não apresentam flores e/ou frutos. Diante disso, realizou-se o presente trabalho cujo objetivo foi a caracterização morfológica e o agrupamento de plantas de rambutan. Foram avaliados: altura da planta (cm), diâmetro e geometria da copa (entre linhas e entre plantas, em cm), diâmetro do tronco (cm) e disposição dos ramos no tronco, tamanho de folhas e folíolos (comprimento e largura, em cm), número de folíolos, comprimento da ráquis (cm), comprimento do pecíolo (cm), área foliar (cm2), vigor das plantas, sensibilidade ao frio, formato dos folíolos, pilosidade, coloração dos folíolos (faces... |

| Shigella spp., the human pathogen responsible for shigellosis, is highly infectious even at low levels. The incidence rate of shigellosis varies with geographical distribution, location human development index, and age groups, being higher among children aged under 5 years. In Brazil, a few works indicate that shigellosis cases are underestimated, with S. flexneri and S. sonnei strains being the major agents responsible for the shigellosis cases. The present study used pulsed field gel electrophoresis (PFGE) to investigate the molecular epidemiology of 119 strains of S. sonnei and S. flexneri isolated from shigellosis cases that occurred in the metropolitan areas of Ribeirão Preto and Campinas Cities, São Paulo Sate, southeast Brazil. The results indicated... |

| This paper presents the first isolation of bovine respiratory syncytial virus in Brazil and its physicochemical, morphological and molecular characterization. The virus was isolated from 33 samples of nasotracheal secretions, successively inoculated into a Madin-Darby bovine kidney cell culture, which was characterized by physicochemical tests and morphological observation by electron microscopy. The Brazilian sample is an RNA pleomorphic, enveloped, thermolabile and non-hemagglutinating spicular virus. Reverse transcription, followed by nested polymerase chain reaction (nRT-PCR) assay was carried out using oligonucleotides B1, B2A, B3 and B4 for the fusion proteins (F) and B5A, B6A, B7A and B8 for the attachment protein (G). The nRT-PCR-F amplified a... |

| ABSTRACT The present investigation deals with the isolation and characterization of a lectin from Aedes aegypti (Ae aegypti) female mid gut extract that agglutinates various mammalian red blood cells (RBCs) such as human three groups A, B, and O (RH+), mouse, rat, guinea-pig, sheep and goat erythrocytes. The highest activity of both crude and isolated mid gut lectins were detected against sheep RBCs. Using (NH4)2 SO4 fractionation, ion-exchange and mannose-CNBr-Sepharose 6B affinity chromatography techniques, Ae. aegypti midgut lectin (Aelec) was purified to homogeneity.Isoelectric focusing (IEF) and reducing SDS/PAGE revealed that the isolated mid gut lectin had isoelectric point (PI) of 5.90, and subunits approximate molecular weights of 35.50 and 27.35... |

| Un total de 129 aislamientos bacterianos obtenidos de la micósfera de esclerocios de Claviceps gigantea se evaluaron in vitro para determinar su capacidad de inhibir el crecimiento de Fusarium graminearum, F. subglutinans y F. verticillioides patógenos a maíz. Ensayos cualitativos en confrontación dual, resultaron en la selección de 22 aislamientos bacterianos con el mayor potencial antagónico hacia una, dos o las tres especies de Fusarium. Los aislamientos se identificaron molecularmente mediante secuenciación parcial del gen 16s ADNr. Las cepas con mayor grado de antagonismo pertenecen a los géneros Bacillus y Pseudomonas. La caracterización en la producción de metabolitos potencialmente involucrados en la actividad antagónica, mostró que el 100% de las... |

| Abstract A new discrete distribution is introduced. The distribution involves the negative binomial and size biased negative binomial distributions as sub-models among others and it is a weighted version of the two parameter discrete Lindley distribution. The distribution has various interesting properties, such as bathtub shape hazard function along with increasing/decreasing hazard rate, positive skewness, symmetric behavior, and over- and under-dispersion. Moreover, it is self decomposable and infinitely divisible, which makes the proposed distribution well suited for count data modeling. Other properties are investigated, including probability generating function, ordinary moments, factorial moments, negative moments and characterization. Estimation of... |

| This paper discusses the importance of studies on materials known as fillers from different mineral origins, used in asphalt mixes, specifically in the formulation of mastics. The research was carried out on samples of limestone and granite rock filler and asphalt binder (50/70). The samples were evaluated through semiquantitative chemical analyses by X-ray fluorescence, granulometry by low angle laser emission, scanning electron microscopy, softening point tests, penetration tests, and aggregate-asphalt binder and aggregate-mastic adhesion tests. The results highlighted convergent trends, indicating that the active behavior of the fillers in the mastic formulation is not related to the size of the particles, but rather to their form, surface texture,... |

| ABSTRACT: The frequency of species of root-knot nematodes (Meloidogyne spp.) was evaluated in weeds collected in different fallow farms in the State of Rio Grande do Sul, Brazil. In the samples where the nematode was found, the species of the root-knot nematode was identified by electrophoresis using the isozyme esterase. They were obtained from weeds belonging to 24 weed species from 13 different botanical families: Amaranthaceae, Asteraceae, Commelinaceae, Convovulaceae, Cyperaceae, Euphorbiaceae, Lamiaceae, Malvaceae, Oxalidaceae, Poaceae, Portulacaceae, Solanaceae, Verbenaceae. Meloidogyne javanica Est J3 (Rm: 1.0, 1.25, 1.40) was the most frequent species and occurred in 53.3% of the samples. M. arenaria with phenotype Est. A2 (Rm: 1.20, 1.30) was... |

| Three distinct forms (Lip A, Lip B and Lip C) of extra-cellular lipases (EC- 3.1.1.3), produced by Candida rugosa in solid state fermentation (SSF) were purified and characterised. SSF was carried out in glass columns using coconut oil cake and wheat bran. The enzyme was purified from the aqueous extract of fermented matter by ammonium sulphate precipitation, dialysis, ultra-filtration and gel filtration using Sephadex-200 to a 43-fold purification and 64.35-mg/ml specific activity. SDS-PAGE of purified enzyme revealed three distinct bands, indicating the existence of three iso-forms, Lip A, Lip B and Lip C with apparent molecular weight about 64,000, 62,000 and 60,000 Da, respectively. All the three iso-forms were optimally active at 35-40°C and pH 7-8.... |

| A caprino-ovinocultura na região Nordeste tem grande importância tanto econômica quanto social, devido ao fato dos animais terem uma boa adaptação ao clima e a alimentação, muitas vezes escassa, disponível na região. A compreensão das cadeias produtivas locais permite a proposição de melhorias no setor a fim de torná-lo mais eficiente. Na caprino-ovinocultura a eficiência ocorre através da oferta aos consumidores de carnes de melhor qualidade, animais jovens, constância de oferta, segurança alimentar e preços competitivos. O resultado da eficiência do sistema produtivo seria de uma maior rentabilidade, uma inserção em novos mercados, ou seja, numa maior competitividade de todo setor. Nesse sentido objetivou-se realizar uma análise descritiva da cadeia... |
