Kawasaki Disease and Human Bocavirus – potential association?
Santos, R. A.; Nogueira, C. S.; Baptista, J. B; Granja, S.; Ribeiro, M. L.; Rocha, M. G.Kawasaki disease (KD) is an acute febrile multisystem vasculitic syndrome of unknown etiology, occurring mostly in infants and children younger than 5 years of age. We present a 13-month-old male with KD from whom was found human bocavirus DNA in nasopharyngeal secretions. Human bocavirus DNA in a patient with KD raised question about the coincidental or possible etiological association.
Different meanings for cummingtonite-hornblende association in plutonic rocks (...
Solá, A. R.; Moita, P.; Santos, J. F.; Neiva, A. M. R.; Ribeiro, M. L.Cummingtonite-grunerite series is frequently related with metamorphism or volcanic environments but rarely described as belonging to a plutonic assemblage [1]. Recently, in Iberian Massif (Portugal), there have been several references [2,3,4,5] of this Fe-Mg amphibole intimately associated with Ca amphiboles (mainly hornblende) on plutonic rocks. Different textural relations between two amphibole types have bee...
Ditribuição de terras raras e outros elementos incompatíveis no Maciço de Monch...
Simão, J.; Bravo, M. S.; Ribeiro, M. L.When approaching a geochemical project a few problems of methodology have to be considered, among them the exploration grid that as to obey to representativity/rentability criteria. This preliminary study permitted to save near 27% on the sampling comparing with the net initially envisaged. Some criteria considered in the elaboration of the grade variation maps and the distribution of two elements in the area a...
Risk markers for progression of mild nonproliferative retinopathy to clinically...
Pereira, I.; Nunes, S.; Ribeiro, M. L.; Bernardes, R.; Cunha-Vaz, J.Purpose To determine risk markers for the development of clinically significant macular edema (CSME) needing photocoagulation treatment in type 2 diabetic patients with mild nonproliferative retinopathy (NPDR), during a 7-year period. Methods Fifty-one type 2 diabetic patients with mild NPDR, followed-up for 2 years as controls of diabetic retinopathy clinical trials, were selected. Patients underwent ophthalmo...
Effect of Helicobacter pylori infection and acid blockade by lansoprazole on cl...
Ortiz,R.A.M.; Calafatti,S.A.; Moraes,L.A.; Deguer,M.; Ecclissato,C.C.; Marchioretto,M.A.M.; Ribeiro,M.L.; Bernasconi,G.; Pedrazzoli Jr,J.The effect of proton pump inhibitors and Helicobacter pylori infection on the bioavailability of antibiotics is poorly understood. We determined the effects of 5-day oral administration of 60 mg lansoprazole on the bioavailability of clarithromycin in individuals with and without H. pylori infection. Thirteen H. pylori-infected and 10 non-infected healthy volunteers were enrolled in a study with an open-randomi...
Prochloraz residue levels in ginger submitted to Sportak 450 CE" postharvest tr...
Polese,L.; Jardim,E. F. G.; Navickiene,S.; Brito,N. M.; Ribeiro,M. L.A preliminary study was conducted to determine the residue levels of prochloraz in ginger samples treated with Sportak 450 CE® (prochloraz as active ingredient) under laboratory conditions and cold-storage for 15 days at 10°C and 89% RH. Sampling was carried out at 10 and 15 days after Sportak 450 CE® dip treatment (450 and 900 µg mL-1). Pesticide residues were determined by GCECD. During the study, residue...
Plasma hydroxy-metronidazole/ metronidazole ratio in hepatitis C virus-induced ...
Marchioretto,M.A.M.; Ecclissato,C.; Silva,C.M.F. da; Cassiano,N.M.; Calafatti,S.A.; Mendonça,S.; Ribeiro,M.L.; Bernasconi,G.C.R.; Degger,M.F.It has been suggested that the measurement of metronidazole clearance is a sensitive method for evaluating liver function. The aim of this study was to evaluate the usefulness of plasma hydroxy-metronidazole/metronidazole ratios as indicators of dynamic liver function to detect changes resulting from the various forms of chronic hepatitis C virus (HCV) infection. A total of 139 individuals were studied: 14 heal...
Rarity of DNA sequence alterations in the promoter region of the human androgen...
Cabral,D.F.; Santos,A.; Ribeiro,M.L.; Mesquita,J.C.; Carvalho-Salles,A.B.; Hackel,C.The human androgen receptor (AR) gene promoter lies in a GC-rich region containing two principal sites of transcription initiation and a putative Sp1 protein-binding site, without typical "TATA" and "CAAT" boxes. It has been suggested that mutations within the 5'untranslated region (5'UTR) may contribute to the development of prostate cancer by changing the rates of gene transcription and/or translation. In ord...
Carbon doping of InAlAs layers grown by metalorganic vapor phase epitaxy
Ribeiro,M. L. P.; Yavich,B.; Tribuzy,C. V. B.; Souza,P. L.Carbon doped AlInAs layers grown by low pressure metalorganic vapor phase epitaxy are investigated as a function of growth temperature. Photoluminescence spectra show a significant drop in peak intensity as the growth temperature is reduced, due to the incorporation of non-radiative defects. It is shown that the C doping is not related to the deterioration of the optical properties of the layers. On the other h...
Allelic frequencies of six polymorphic markers for risk of prostate cancer
Ribeiro,M.L.; Santos,A.; Carvalho-Salles,A.B.; Hackel,C.The aim of the present study was to evaluate the distribution of polymorphisms for the androgen receptor (AR) (CAG, StuI, GGN), SRD5A2 (Ala49Thr, Val89Leu) and CYP17 (MspA1) genes that are considered to be relevant for risk of prostate cancer. We studied 200 individuals from two cities in the State of São Paulo, by PCR, PCR-RFLP and ASOH techniques. The allelic frequencies of the autosomal markers and the StuI ...
