In silico analysis of mismatches in RT-qPCR assays of 177 SARS-CoV-2 sequences from Brazil

Abstract INTRODUCTION: Quantitative reverse transcription polymerase chain reaction (RT-qPCR) can detect the severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) in a highly specific manner. However, a decrease in the specificity of PCR assays for their targets may lead to false negative result...

Untargeted contrast-enhanced ultrasound versus contrast-enhanced computed tomography: a differential diagnostic performance (DDP) study for kidney lesions

Clinics; 75 (), 2020
OBJECTIVES: Histopathology is the 'gold standard' for diagnosing renal cell carcinoma but is limited by sample size. Contrast-enhanced ultrasound can differentiate malignant and benign lesions, but the Chinese guidelines on the management of renal cell carcinoma do not include this method. The purpose of...

Posturographic measures did not improve the predictive power to identify recurrent falls in community-dwelling elderly fallers

Clinics; 75 (), 2020
OBJECTIVE: This study aimed to evaluate if posturography can be considered a recurrent fall predictor in elderly individuals. METHODS: This was a cross-sectional study. A total of 124 subjects aged 60 to 88 years were evaluated and divided into two groups—the recurrent fallers (89) and single fall...

Gelatinasas como marcadores de consumo crónico de alcohol: un estudio piloto en Uruguay

El consumo crónico de alcohol en Uruguay es un problema creciente, sin embargo, las determinaciones de biomarcadores consensuados no se realizan sistemáticamente ni se investigan otros marcadores potenciales. Para validar la hipótesis de que las metaloproteinasas de matriz con actividad gelatinasa son...

Evaluation of Toxocara canis Glycosylated TES Produced in Pichia pastoris for Immunodiagnosis of Human Toxocariasis

Abstract Recombinant proteins are a suggested alternative for the diagnosis of toxocariasis. The current Escherichia coli recombinant protein overexpression system usually produces insoluble products. As an alternative, yeast such as Pichia pastoris have secretory mechanisms, which could diminish the cos...
