1. Bullous pemphigoid and milia: prevalence and clinical laboratory findings in a Brazilian sample
Abstract Background: Bullous pemphigoid (BP) associated with milia lesions has been increasingly reported, but its prevalence has not been reported in a Brazilian BP population yet. Objectives: To describe the occurrence and clinical-laboratorial findings of BP-milia association in a southeastern Brazilian sample. Methods: A descriptive study based on the

2. Cost minimization analysis of an in-house molecular test for cytomegalovirus in relation to a commercial molecular system
ABSTRACT Introduction: Cytomegalovirus may cause severe disease in immunocompromised patients. Nowadays, quantitative polymerase chain reaction is the gold-standard for both diagnosis and monitoring of cytomegalovirus infection. Most of these assays use cytomegalovirus automated molecular kits which are expensive and therefore not an option for small labora

3. Laboratory investigations in the diagnosis and follow-up of GH-related disorders
ABSTRACT In addition to auxiological, clinical and metabolic features measurements of growth hormone (GH) and insulin-like growth factor I (IGF-I) complement our tools in diagnosis and follow-up of GH-related disorders. While comparably robust during the pre-analytical phase, measurement and interpretation of concentrations of both hormones can be challengin

4. Evaluating the discriminatory power of a dissolution assay for rosuvastatin calcium capsules: Solid-state properties and dissolution media
We propose to evaluate the dissolution properties of rosuvastatin calcium (ROSC) capsules in different media to characterize the discriminatory power of the assay method. Dissolution assays were performed in media with different pH, and including the surfactant sodium dodecyl sulfate (SDS). Several immediate-release formulations were manufactured using the c

5. Saliva collection and detection of anti- T. gondii antibodies of low-income school-age children as a learning strategy on hygiene, prevention and transmission of toxoplasmosis
ABSTRACT School-age children are a social group in which blood collection for laboratory testing can be perceived as an invasive procedure, with low acceptance and tolerance of stakeholders. This problem could be circumvented by replacing serum samples with saliva. For this purpose, and to make the collection of saliva samples playful and instructive for chi

6. BINARY CO-CULTURE SELECTION FROM MARINE-DERIVED MICROORGANISMS FOR DIFFERENTIAL PRODUCTION OF SPECIALIZED METABOLITES
Nowadays the discovery of new compounds from microorganisms has substantially decreased. Genomic studies have shown that certain genes are not expressed under standard laboratory conditions. In order to overcome this problem, several methods including microorganism co-culture have been developed. The aim of this work was to select binary co-cultures of marin

7. Diagnostic accuracy of Enzyme-Linked Immunosorbent Assays to detect anti-Leishmania antibodies in patients with American Tegumentary Leishmaniasis: a systematic review
ABSTRACT American Tegumentary leishmaniasis (ATL) is an infectious disease caused by several species of Leishmania . Even though the direct detection of parasites has low sensitivity, it is still the gold standard for the laboratory diagnosis of ATL. Recent studies have shown promising results of Enzyme-Linked Immunosorbent Assays ( ELISAs) using recombinant

8. Validation of chromogenic in situ hybridization reactions for DNA and RNA detection in formalin-fixed paraffin-embedded tissue
RESUMO Introdução: A hibridização in situ cromogênica (CISH) é uma alternativa aos métodos tradicionais imuno-histoquímicospara diagnóstico de doenças infecciosas em amostras fixadas em formalina e incluídas em parafina, visto que apresenta grande sensibilidade e especificidade. Esse tipo de amostra sofre diversas modificações químicas durante

9. Deterioration of Teak Wood in Accelerated Decay Test
ABSTRACT The present study aimed to evaluate the biological resistance of teak (Tectona grandis) heartwood and sapwood to the action of Trametes versicolor and Gloeophyllum trabeum fungi in laboratory accelerated decay assays. The mass loss evaluation of the samples was performed periodically. The heartwood presented a higher percentage of extractives and th

10. West Nile virus infections are here! Are we prepared to face another flavivirus epidemic?
Abstract Emerging arthropod-borne viruses (arboviruses), such as chikungunya and Zika viruses, are a major threat to public health in countries like Brazil where biodiversity is high and medical care is sometimes precarious. West Nile fever is a disease caused by the West Nile Virus (WNV), an RNA virus belonging to the Flaviviridae family. It is transmitted

11. Behavior of the chromite tailings in a centrifugal concentrator (FALCON)
Abstract The application of the centrifugal concentration gains importance in the world scenario, considering the low environmental impact and the concentration of fine particles. Literature does not present articles using centrifugal concentration (Falcon) for chromite. The material used in the tests is the tailings from a Northeastern Brazil concentration

12. Endothelial Dysfunction and Pulse Wave Reflection in Women with Polycystic Ovarian Syndrome
Abstract Background: Patients with polycystic ovarian syndrome (PCOS) have an increased prevalence of metabolic syndrome and traditional atherosclerotic risk factors, such as dyslipidemia, diabetes and hypertension. Endothelial function and vascular stiffness are surrogate markers of early atherosclerosis, able to predict cardiovascular events. Objective:
