1. Social cognition and suicide-related behaviors in depression: a cross-sectional, exploratory study
Objective: To explore the association between social cognition and previous suicide attempts and non-suicidal self-injurious behavior in adults with unipolar depressive disorders. Methods: Seventy-two patients undergoing outpatient treatment for unipolar depression were enrolled in this cross-sectional study. Theory of mind was assessed using the Hinting Ta

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. 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

4. IgE antibodies from schistosomiasis patients to recognize epitopes in potato apyrase
Abstract INTRODUCTION: High percentages of structural identity and cross-immunoreactivity have been reported between potato apyrase and Schistosoma mansoni ATP diphosphohydrolase (SmATPDases) isoforms, showing the existence of particular epitopes shared between these proteins. METHODS: Potato apyrase was employed using ELISA, western blot, and mouse immu

5. Prevalence and reactivity of anti-melanoma differentiation-associated gene 5 (anti-MDA-5) autoantibody in Brazilian patients with dermatomyositis
Abstract: Background: There have been no studies to date on the frequency and reactivity of aanti-melanoma differentiation-associated gene 5 (anti-MDA-5) in samples from the Brazilian population with dermatomyositis. Objectives: To analyze this autoantibody in the Brazilian population. Methods: This was a single-center cross-sectional study in which 131 c

6. Development and characterization of an immunoaffinity column for the detection of danofloxacin residues in milk samples
Abstract In this study, an immunoaffinity column was prepared by covalently coupling of polyclonal antibody against danofloxacin (DAN) with chitosan microparticles and its potential application to selective extraction of DAN from food samples was also evaluated. The produced antibody exhibited high sensitivity, with an IC50 value of 4.56 ng/mL towards DAN,

7. Searching for the best real-time RT-PCRs to detect Zika virus infections: the importance of comparing several protocols
Clinical manifestations of Zika, dengue, and chikungunya virus infections are very similar, making it difficult to reach a diagnosis based only on clinical grounds. In addition, there is an intense cross-reactivity between antibodies directed to Zika virus and other flaviviruses, and an accurate Zika diagnosis is best achieved by real-time RT-PCR. However, s

8. Translation and validation of Warmometer, a tool for assessing warmth in patient-provider relationships, for use in Brazilian Portuguese
ABSTRACT BACKGROUND: Empathy in the patient-provider relationship is associated with important outcomes in healthcare practice. Our aim was to translate and validate Warmometer, a visual tool for assessing warmth in patient-provider relationships, for use in Brazilian Portuguese. DESIGN AND SETTING: Cross-sectional study conducted at an antenatal clinic

9. Will Mayaro virus be responsible for the next outbreak of an arthropod-borne virus in Brazil?
Abstract Mayaro virus is an alphavirus from the Togaviridae family and is transmitted mainly by Hemagogus mosquitoes. This virus circulates in high-density tropical forests or rural areas of Central and South America causing a disease characterized by high-grade fever, maculopapular skin rash and marked arthralgia that, in some patients, can persist for long

10. Antivenomics as a tool to improve the neutralizing capacity of the crotalic antivenom: a study with crotamine
Abstract Background Snakebite treatment requires administration of an appropriate antivenom that should contain antibodies capable of neutralizing the venom. To achieve this goal, antivenom production must start from a suitable immunization protocol and proper venom mixtures. In Brazil, antivenom against South American rattlesnake (Crotalus durissus terrif

11. Biological and molecular properties of yellow venom of the Amazonian coral snake Micrurus surinamensis
Abstract INTRODUCTION: The coral snake Micrurus surinamensis, which is widely distributed throughout Amazonia, has a neurotoxic venom. It is important to characterize the biological and molecular properties of this venom in order to develop effective antitoxins. METHODS: Toxins from the venom of M. surinamensis were analyzed by two-dimensional polyacryla

12. Rats treated with Hypericum perforatum during pregnancy generate offspring with behavioral changes in adulthood
Abstract Drugs used in the treatment of depression can cross the placenta giving rise to questions regarding the effects these drugs exert on the fetus. Hypericum perforatum L., Hypericaceae, is a natural product used to treat depression. However, information about its toxicity and the occurrence of alterations in the central nervous system development of th
