Estudio comparativo entre un test de antígeno y la prueba de la reacción en cadena de la polimerasa en tiempo real (RT-PCR) para el diagnóstico de infección por COVID-19 en pediatría

Arch. argent. pediatr; 121 (5), 2023
Introducción. La pandemia por COVID-19 ha puesto de manifiesto la necesidad de pruebas diagnósticas rápidas. La prueba de referencia es la reacción en cadena de la polimerasa en tiempo real (RT-PCR). Requiere un equipo y personal capacitado, y su resultado puede llevar un tiempo de espera prolongado....

Detection of coronavirus-2 by real-time reverse transcription polymerase chain reaction in conjunctival swabs from patients with severe form of Coronavirus disease 2019 in São Paulo, Brazil

Clinics; 76 (), 2021
OBJECTIVES: To test conjunctival swabs from patients with laboratory-confirmed severe forms of coronavirus disease 2019 (COVID-19) for the presence of SARS-CoV-2 on real-time reverse-transcription polymerase chain reaction (rRT-PCR). METHODS: Fifty conjunctival swabs were collected from 50 in-patients w...

Serum expression of microRNA-16 in a cohort of Egyptian patients with ulcerative colitis and its correlation with disease extent and severity

Abstract Ulcerative colitis is one of the IBDs. Its etiology and pathogenesis remain undefined with an interaction between environmental, genetic and immunological factors is the most accepted explanation. Several recent studies have examined microRNA expression in the peripheral blood and tissues from I...

Frecuencia de aberraciones moleculares en pacientes cubanos con leucemia mieloide aguda
Frequency of molecular disorders in Cuban patients with acute myeloid leukemia

Introducción: En el Instituto de Hematología e Inmunología se realiza el estudio molecular de las leucemias mieloides agudas (LMA). Para las leucemias mieloides agudas no promielocíticas (LPM) se determinan cuatro biomarcadores: los genes de fusión RUNX1-RUNX1T1 y CBF(-MYH11, la duplicación intern...

Monitorización de la capacidad de degradación de las nuevas bacterias haloalcalifílicas resistentes a cloruro de tributiltina (TBTCl) en una ubicación contaminada por butiltina
Monitoring the degradation capability of novel haloalkaliphilic tributyltin chloride (TBTCl) resistant bacteria from butyltin-polluted site

Rev. argent. microbiol; 51 (1), 2019
Tributyltin (TBT) is recognized as a major environmental problem at a global scale. Haloalkaliphilic tributyltin (TBT)-degrading bacteria may be a key factor in the remediation of TBT polluted sites. In this work, three haloalkaliphilic bacteria strains were isolated from a TBT-contaminated site in the M...

Molecular characterization and expression analysis of cathepsin C in Chinese giant salamander (Andrias davidianus) after Aeromonas hydrophila infection

Background: Cathepsin C (CTSC) (dipeptidyl peptidase I, DPPI), is a member of the papain superfamily of cysteine proteases and involves in a variety of host reactions. However, the information of CTST in Chinese giant salamander (Andrias davidianus), an amphibian species with important evolutionary posit...

Cadmium-induced apoptosis of Siberian tiger fibroblasts via disrupted intracellular homeostasis

Biol. Res; 49 (), 2016
BACKGROUND: Heavy metals can cause great harm to Siberian tigers in the natural environment. Cadmium (Cd2+) is an environmental contaminant that affects multiple cellular processes, including cell proliferation, differentiation, and survival. It has been shown to induce apoptosis in a variety of cell typ...

Olfactomedin-like 2 A and B (OLFML2A and OLFML2B) expression profile in primates (human and baboon)

Biol. Res; 49 (), 2016
BACKGROUND: The olfactomedin-like domain (OLFML) is present in at least four families of proteins, including OLFML2A and OLFML2B, which are expressed in adult rat retina cells. However, no expression of their orthologous has ever been reported in human and baboon. OBJECTIVE: The aim of this study was to ...
