1. Novel N-Heterocyclic Carbene Silver(I) Complexes: Synthesis, Structural Characterization, Antimicrobial and Cytotoxicity Potential Studies
In this study, a series of unsymmetrical N,N-disubstituted benzimidazolium salts were synthesized as N-heterocyclic carbene (NHC) (2a-2j) and their AgI complexes. Their structures were characterized by elemental analyses, 1H and 13C nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy techniques. Further, both the salts and their silver(I)-NHC com

2. Inclusion complexes and self-assembled cyclodextrin aggregates for increasing the solubility of benzimidazoles
Albendazole and fenbendazole are imidazole derivatives that exhibit broad spectrum activity against parasites, but the low solubility of these drugs considerably reduces their effectiveness. Complexation of albendazole and fenbendazole with cyclodextrins (β-cyclodextrin and hydroxypropyl-β-cyclodextrin) in both water and an aqueous solution of polyvinylpyr

3. Cationic Micellar Precipitation for Simultaneous Preconcentration of Benzimidazole Anthelmintics in Milk Samples by High-Performance Liquid Chromatography
A method using micellar precipitation process using cationic surfactant cetyltrimethyl ammonium bromide at ambient temperature was investigated for simultaneous determination of benzimidazoles coupled with high-performance liquid chromatography (HPLC) analysis. The studied benzimidazoles was selected as model compounds including thiabendazole, albendazole, m

4. Simple, mild, and highly efficient synthesis of 2-substituted benzimidazoles and bis-benzimidazoles
A new convenient method for preparation of 2-substituted benzimidazoles and bis-benzimidazoles is presented. In this method, o-phenylenediamines were condensed with bisulfite adducts of various aldehydes and di-aldehydes under neat conditions by microwave heating. The results were also compared with results of synthesis by conventional heating under reflux.

6. Isolamento de fungos degradadores de carbendazim.
Os fungicidas sistemicos do grupo dos benzimidazois sao amplamente utilizados no controle de muitas doencas de plantas, tanto no solo como na parte aerea, e isso tem sido causa de contaminacao ambiental. A acao de alguns microorganismos contribui para degradacao e perda da atividade biologica desses fungicidas, podendo reduzir, dessa forma, o risco de impact

7. Sensibilidade a fungicidas e adaptabilidade de Lasiodiplodia theobromae patogênico ao mamão
Application of fungicide is the main measure of management to stem-end rot and there is no information on the sensitivity and on the fitness costs arising from the reduction in sensitivity of its causal agent, Lasiodiplodia theobromae. One hundred and twenty monosporic isolates collected in producing areas of the Northeast region of Brazil, were divided into

8. SENSIBILITY IN VITRO and IN VIVO OF Colletotrichum lindemuthianum (Sacc &Magn.) Briosi &Cav., THE SYSTEMIC FUNGICIDES / SENSIBILIDADE IN VITRO E IN VIVO DE ISOLADOS DE Colletotrichum lindemuthianum (Sacc &Magn.) Briosi &Cav., A FUNGICIDAS SISTÊMICOS
A sensibilidade in vitro e in vivo de dez isolados de Colletotrichum lindemuthianum a fungicidas sistêmicos foi avaliada in vitro e in vivo, em delineamento experimental inteiramente casualizado com três repetições. No estudo in vitro foi avaliada a porcentagem de germinação de conídios do fungo quando submetidos aos fungicidas benzimidazóis: carbend

9. Characterization and identification of Colletotrichum species associated to anthracnose in pepper (Capsicum annuum) in Brazil / Caracterização e identificação de espécies de Colletotrichum associadas à antracnose do pimentão (Capsicum annuum) no Brasil
In several countries, anthracnose is one of the most serious diseases in pepper. C. gloeosporioides has, for many years, been reported as the causal agent of anthracnose in Brazil. C. acutatum and C. capsici have only recently been reported as agents of anthracnose in some regions of the country. In this study, 56 isolates of Colletotrichum obtained from pep

10. Validação de metodologia analítica para o doseamento simultâneo de mebendazol e tiabendazol por cromatografia líquida de alta eficiência
The aim of this work was to develop and validate an analytical methodology for simultaneous determination of mebendazole and thiabendazole, two benzimidazoles used as anthelmintics. The method was based on high performance liquid chromatography, using a C18 column, a mobile phase composed of KH2PO4 0.05 mol L-1 and methanol 40:60 (v/v) and UV detection at 31

11. Resistência de Didymella bryoniae a fungicidas no Brasil
O crestamento gomoso do caule (Didymella bryoniae) é uma das mais importantes doenças da melancia (Citrullus lanatus) no mundo. O controle químico, embora amplamente adotado, nem sempre pode impedir o progresso da doença no campo. A resistência do agente causal a alguns ingredientes ativos foi relatada na Europa, Japão e nos Estados Unidos, porém nenh

12. Gastroesphageal reflux disease : influence of cagA strains of Helicobacter pylori in the proton pump inhibition therapeutic response in patients with low grade erosive esophagitis / "Doença do refluxo gastroesofágico: influência da cepa cagA do Helicobacter pylori na resposta terapêutica à inibição da bomba protônica em pacientes com esofagite erosiva leve"
Eighty three patients with grade I-II of the modified Savary-Miller classification have been studied. They were divided in three groups. One without Helicobacter pylori infection, two with the bacterium, one with and other without the cagA gene. We verified the influence of cagA status, histopathology of antrum and body of the stomach and gastrinemia in the
