Primary antibiotic resistance of helicobacter pylori strains isolated from Port...
Oleastro, M; Cabral, J; Ramalho, P; Lemos, P; Paixão, E; Benoliel, J; Santos, A; Lopes, AOBJECTIVES: The aim of this study was to prospectively assess the pattern of evolution of primary resistance to antibiotics in Helicobacter pylori strains isolated from Portuguese children over a 10 year period (2000-09). METHODS: A total of 1115 H. pylori strains were tested for antibiotic susceptibility to clarithromycin, metronidazole, amoxicillin, ciprofloxacin and tetracycline. RESULTS: H. pylori strains...
Chemical composition and larvicidal activity of Rollinia leptopetala (Annonaceae)
Feitosa,Edinilza M. A.; Arriaga,Ângela M. C.; Santiago,Gilvandete M. P.; Lemos,Telma L. G. de; Oliveira,M. Conceição F. de; Vasconcelos,Jackson Nunes eThe aim of present study was to describe the chemical composition of the essential oils from the leaf and stem of Rollinia leptopetala R. E. Fries (Annonaceae) and to evaluate the larvicidal activities of these essential oils, of the methanol extract from roots of this plant and of the oxoaporphine alkaloid, liriodenine (1) against the third-instar of Aedes aegypti larvae. The methanol extract from the roots sh...
Intoxicação por Stryphnodendron fissuratum (Mimosoideae) em bovinos
Ferreira,Eduardo V.; Boabaid,Fabiana M.; Arruda,Laura P.; Lemos,Ricardo A.A.; Souza,Marcos A.; Nakazato,Luciano; Colodel,Edson M.Descrevem-se aspectos epidemiológicos, clínicos e patológicos da intoxicação natural por Stryphnodendron fissuratum em bovinos na região Centro-Oeste do Brasil. Esta planta possui favas retorcidas, conhecidas popularmente por "rosquinha", que amadurecem entre julho e setembro, caem ao solo e são consumidas por bovinos, sendo relacionadas com mortalidades. Foram investigados surtos de intoxicação espontânea que ...
Oxidative Stress in Cyclosporine-Induced Hypertension: Evidence of Beneficial E...
Reis, F.; Rocha-Pereira, P.; Lemos, E. Teixeira de; Parada, B.; Baptista, S.; Figueiredo, A.; Santos-Silva, A.; Costa-Almeida, C.; Mota, A.The aim of this study was to evaluate the effect of cyclosporine (CsA) on oxidative stress as well as the use of a nitric oxide (NO) donor, the organic nitrate isosorbide-5-mononitrate (Is-5-Mn), to prevent or reverse CsA-induced toxicity, namely on the vascular NO-cGMP pathway or on oxidative equilibrium. The following rat groups (n = 8) were tested: (1) a control group; (2) the CsA group (5 mg/kg/d for 7 week...
Hyperhomocystinemia in patients with coronary artery disease
Faria-Neto,J.R.; Chagas,A.C.P.; Bydlowski,S.P.; Lemos Neto,P.A.; Chamone,D.A.; Ramirez,J.A.F.; da Luz,P.L.Hyperhomocystinemia has been related to an increased risk of cardiovascular disease in several studies. The C677T polymorphism for the gene that encodes the methylenetetrahydrofolate reductase enzyme (MTHFR) and low plasma folate levels are common causes of hyperhomocystinemia. Due to differences in nutritional patterns and genetic background among different countries, we evaluated the role of hyperhomocystinem...
Development of a scar marker for Pierce's Disease strains of Xylella fastidiosa
Travensolo,Regiane F.; Ciapina,Luciane P.; Lemos,Eliana G. M.The objective of this research was to develop a primer for a polymerase chain reaction specific for Xylella fastidiosa strains that cause Pierce's Disease (PD) in grapes (Vitis vinifera). The DNA amplification of 23 different strains of X. fastidiosa, using a set of primers REP1-R (5'-IIIICGICGIATCCIGGC-3') and REP 2 (5'-ICGICTTATCIGGCCTAC-3') using the following program: 94 ºC/2 min; 35 X (94 ºC/1 min, 45 ºC/1...
Carcinoma anaplásico da tiróide: análise retrospectiva de 12 casos
Martins, TD; Carrilho, F; Leitão, P; Lemos, MC; Campos, MV; Geraldes, E; Carvalheiro, MAnaplastic thyroid tumor is a rare tumor and constitutes 5 to 10% of thyroid carcinomas. Is one of the most aggressive solid tumors and the prognosis is always fatal with a mean survival of 3 to 7 months. The current therapeutics are scarce and inefficacious. A retrospective analysis was performed in 12 clinical cases of anaplastic thyroid tumor observed at the Department of Endocrinology, Diabetes and Metaboli...

Qualidade fisiológica de sementes de araçazeiro durante o armazenamento
Cisneiros,Roberta A.; Matos,Valderez P.; Lemos,Margarida A.; Reis,Odemar V. dos; Queiroz,Rosilda de M.O presente trabalho teve como objetivo avaliar diferentes ambientes de armazenamento e embalagens quanto à eficiência na manutenção da qualidade das sementes de araçazeiro (Psidium guineenseSwartz) durante 180 dias. As sementes foram provenientes de frutos recém-colhidos completamente maduros e de oito acessos do banco ativo de germoplasma do araçazeiro localizado na Estação Experimental de Itapirema, da Empres...
