1. Salivary Cortisol and Sustained Auditory Attention in Children with and without Cleft Lip and Palate
Abstract Introduction Cortisol is a hormone involved in the response to stress. Attention is a function that can change due to exposure to stress. Objectives To verify the correlation between the level of salivary cortisol and sustained auditory attention in children with cleft lip and palate, as well as to compare the results of the variables analyzed bet

2. Genotypes of Epstein–Barr virus (EBV1/EBV2) in individuals with infectious mononucleosis in the metropolitan area of Belém, Brazil, between 2005 and 2016
Abstract Two types of Epstein Barr virus (EBV1/EBV2) have been shown to infect humans. Although their genomes are similar, the regions containing the EBNA genes differ. This study aimed to characterize the EBV genotypes of infectious mononucleosis (IM) cases in the metropolitan region of Belém, Brazil, from 2005 to 2016. A total of 8295 suspected cases with

3. MONITORING OF PROGESTERONE AND ESTRONE FECAL METABOLITES THROUGHOUT GESTATION IN EWES
Resumo O objetivo deste estudo foi monitorar os níveis de metabólitos fecais de progesterona e estrona ao longo da gestação em ovelhas, correlacionando-os com os níveis séricos desses hormônios esteroides. Assim, amostras de fezes e sangue foram colhidas de cinco ovelhas no período pré-cobertura e durante a gestação, até duas semanas após o part

5. SUMA Technology and Newborn Screening Tests for Inherited Metabolic Diseases in Cuba: An Overview of the First 30 Years
Abstract The ultramicroanalytic system (SUMA), created in the 1980s, is a complete system of reagents and instrumentation to perform ultramicroassays combining the sensitivity of the micro-enzyme-linked immunosorbent assay (ELISA) tests with the use of ultramicrovolumes. This technology permitted establishing large-scale newborn screening programs (NSPs) for

6. A Novel Colorimetric Immunoassay of Ultrasensitive Alpha-Fetoprotein Sensing in Magnetic Bead-Based Mimic Enzyme-Chromogenic Substrate System
This work described a simple and feasible colorimetric immunoassay. Using hemin (a horseradish peroxidase (HRP) mimic enzyme) and the mimic enzyme-chromogenic substrate system, it can qualitatively and quantitatively detect a-fetoprotein (AFP) at an ultralow concentration. The glucose oxidase (GOx) catalyzed oxidation of glucose leads to the formation of glu

7. Can Aspergillus fumigatus conidia cause false-positive results in the galactomannan enzyme immunoassay test?
Abstract INTRODUCTION: Several factors can cause false-positive results in the galactomannan (GM) test; however, others remain unknown. Presently, the impact of airborne contamination by Aspergillus conidia during enzyme-linked immunosorbent assay (ELISA) remains uninvestigated. METHODS: We studied 12 A. fumigatus isolates. Fungal conidia were serially d

8. Erythrodermic psoriasis and human immunodeficiency virus: association and therapeutic challenges
Abstract: Erythrodermic psoriasis is a rare but severe type of psoriasis that may be triggered by human immunodeficiency virus infection. We describe the case of a 65-year-old male patient with chronic psoriasis who presents an exacerbation of his condition over a period of two weeks. Because of the severity of his case and subsequent need for systemic thera

9. Sensitivity, specificity and comparison of three commercially available immunological tests in the diagnosis of Cryptosporidium species in animals
ABSTRACT The study was conducted to compare the specificity of immunological diagnostic methods used for the diagnosis of Cryptosporidium species capable of causing life-threatening infection in both immunosuppressed and immunocompetent patients. For the detection of Cryptosporidium species in 79 animals with diarrhoea, we used three Copro-antigen tests: RID

10. Paracoccidioidomycosis due to Paracoccidioides brasiliensis S1 plus HIV co-infection
BACKGROUND Paracoccidioidomycosis (PCM) is one of the most important systemic mycoses in Latin America and the leading fungal cause of mortality in non-immunosuppressed individuals in Brazil. However, HIV/PCM co-infection can increase the clinical severity in these co-infected patients. This co-infection is rarely reported in the literature mainly because o

11. Association between seroprevalence of IgG anti-Toxoplasma gondii and risk factors for infection among pregnant women in Climério de Oliveira Maternity, Salvador, Bahia, Brazil
ABSTRACT Maternal Toxoplasma gondii (T. gondii) infection can lead to spontaneous abortion, fetal malformation, and numerous sequelae in the newborn, including visual and hearing impairment. T. gondii serology was determined in pregnant women and their newborns who were referred to Climério de Oliveira Maternity, Federal University of Bahia, and the possibl

12. Survey of mycotoxins in Southern Brazilian wheat and evaluation of immunoassay methods
ABSTRACT One hundred commercial wheat grain samples were collected during the 2015 sea-son across 78 municipalities in the states of Paraná (PR), Rio Grande do Sul (RS), and São Paulo (SP), Brazil. Separate subsamples were analyzed for the concentration of deoxynivalenol (DON), zearalenona (ZEA) and ochratoxin A (OTA) mycotoxins using two methods: UHPLC-MS
