1. Development of a TD-NMR Method to Monitor Brazil Nuts Oil Content: A Green and Low-Cost Based Approach
Growth in the international popularity of Brazil nuts oil (Bertholletia excelsa, Bonpl.) has demanded a closer look at quality aspects of the nuts. In this context, time-domain 1H nuclear magnetic resonance spectroscopy (TD-NMR) can be a useful tool for assessing the lipid portion of such matrices. In this work, a TD-NMR method was developed and validated to

2. ISO/IEC 17025: history and introduction of concepts
Quality is an increasingly present concept nowadays, so meeting the customers’ needs, who buy and use products and hire services, becomes essential. For laboratories, the concept is applied to the reliability and traceability of the results produced and presents itself not only to meet the customer’s needs, but also to allow the signing of agreements in

3. Inclusion of molecular monitoring (BCR-ABL1) in the treatment of chronic myeloid leukemia in the Brazilian Public Health System (SUS): an urgent need for treatment management
ABSTRACT Introduction: Chronic Myeloid Leukemia (CML) is a myeloproliferative disease that affects mainly adults between 50 and 55 years. In Brazil, information from the Sistema Único de Saúde (SUS) Outpatient Information System indicates that 12,531 patients had the Autorização de Procedimento Ambulatorial (APAC) approved for the CML treatment in 2017.

7. Longitudinal analysis of laboratory tests in a population-based study
RESUMO Os laboratórios clínicos devem ter sistemas de gestão da qualidade que garantam a fidedignidade dos resultados. Ainda, em estudos longitudinais, é importante que os dados gerados sejam analisados ao longo do tempo, como medida adicional de controle de qualidade (CQ), buscando identificar flutuações não explicáveis por variáveis biológicas.

9. Usefulness of a multiplex PCR for the rapid identification of Candida glabrata species complex in Mexican clinical isolates
ABSTRACT Candida glabrata complex includes three species identified through molecular biology methods: C. glabrata sensu stricto , C. nivariensis and C. bracarensis . In Mexico, the phenotypic methods are still used in the diagnosis; therefore, the presence of C. nivariensis and C. bracarensis among clinical isolates is still unknown. The aim of this study w

10. Analytical validation of real-time quantitative PCR assays for optimum diagnosis of vivax malaria
BACKGROUND The prompt diagnosis of plasmodial species for effective treatment prevents worsening of individual health and avoids transmission maintenance or even malaria reintroduction in areas where Plasmodium does not exist. Polymerase chain reaction (PCR) allows for the detection of parasites below the threshold of microscopic examination. OBJECTIVE O
