Nonselective beta-blockers and the risk of portal vein thrombosis in patients w...
Nery, F; Correia, S; Macedo, C; Gandara, J; Lopes, V; Valadares, D; Ferreira, S; Oliveira, J; Gomes, MT; Lucas, R; Rautou, PE; Miranda, HP; Valla, DBackground Nonmalignant portal vein thrombosis is a significant event in the course of cirrhosis that can contraindicate liver transplantation and even impact survival after the surgical procedure. Risk factors are not completely known or validated and are still debated. Aim To identify in patients with cirrhosis the risk factors for portal vein thrombosis that are assessable in clinical practice. Methods Betwe...
Efficacy and Safety of Direct-Acting Oral Anticoagulants Use in Acute Portal Ve...
Nery, F; Valadares, D; Morais, S; Gomes, MT; de Gottardi, AIn acute portal vein thrombosis (APVT) unrelated to cirrhosis, anticoagulant therapy is classically started with low molecular weight heparin or vitamin K antagonists. New direct-acting oral anticoagulants (DOACs) are used in the treatment of venous thrombosis outside the splanchnic vascular bed, but not in the latter. We report a young female with APVT occurring in a non-cirrhotic liver linked to heterozygosit...
The utilisation of a piezoelectric quartz crystal for measuring carbon dioxide ...
Gomes, MT; Duarte, A C; Oliveira, JPA piezoelectric quartz crystal (PQC) is used for the quantification of carbon dioxide in still white wine. The methodology is discussed in terms of calibration stability and accuracy as a direct consequence of coating amount and absolute quantity of carbon dioxide in the samples. The method is compared, in terms of precision, with the titrimetric method. Standard deviations for several wine samples are, in the ...
Determination of sulfur dioxide in wine using a quartz crystal microbalance
Gomes, MT; Rocha, TA; Duarte, AC; Oliveira, JPA new method for the analysis of both total and bound SO2 in wine is proposed, based on a quartz crystal microbalance (QCM), and it is compared with the widely used Ripper method. The proposed method is faster than the Ripper's, and the instrumentation is either homemade or widely available. When both methods are applied to the same sample, the results obtained using the QCM method are bracketed in an interval ...
Study on the methodology for the quantification of carbon dioxide in wine using...
Gomes, MT; Duarte, AC; Oliveira, JPA new method for carbon dioxide (CO2) determination in wine is proposed, based on the use of a quartz crystal microbalance. The analytical experimental set-up was made in the laboratory, and the methodology, free of interference and with an easy calibration procedure, is adequate to monitor CO2 in wine.
