Trombosis senovenosa cerebral en un recién nacido con mutación MTHFR C677T tratado con enoxaparina

Rev. chil. pediatr; 91 (3), 2020
Resumen: Introducción: La trombosis senovenosa cerebral neonatal (TSVC), es una patología rara y generalmente grave, de la cual se conoce poco sobre los mecanismos fisiopatológicos responsables y, aunque controvertido, se ha sugerido que la trombofilia genética, puede desempeñar un rol en la patog...

Asociación entre el polimorfismo rs9939609 del gen FTO y marcadores de adiposidad en población infantil chilena

Rev. chil. pediatr; 91 (3), 2020
Resumen: Introducción: La obesidad es una enfermedad inflamatoria donde la genética determina cierto nivel de riesgo. Aun cuando existen estudios que reportan asociación entre polimorfismos de FTO (fat-mass associated gene) y adiposidad, existe limitada evidencia en población infantil chilena. Obj...

Contribution of rs1799998 polymorphism in CYP11B2 gene in susceptibility to preeclampsia

Abstract Objectives: the present study aimed to evaluate the association between the rs1799998 polymorphism of the CYP11B2 gene and the susceptibility to preeclampsia (PE) in a Brazilian population. Methods: the study group comprised 61 women who were diagnosed with PE. The control group included 116 w...

Genome-wide development of polymorphic microsatellite markers and their application in peanut breeding program

BACKGROUND: Cultivated peanut (Arachis hypogaea. L) represents one of the most important oil crops in the world. Although much effort has been expended to characterize microsatellites or Simple Sequence Repeats (SSRs) in peanut, the quantity and quality of the markers in breeding applications remain limi...

Marcadores moleculares para la taxonomía e identificación del género Brucella (Alphaproteobacteria)
Molecular markers for the taxonomy and identification of the genus Brucella (Alphaproteobacteria)

Introducción: El género Brucella está incluido en la familia Brucellaceae que pertenece al orden Rhizobiales y es reconocido por su alto grado de patogenicidad. Las bacterias de este género son responsables de la brucelosis, enfermedad que ha sido reportada como una de las zoonosis más importantes ...

Chromosomal analysis of Centromochlus heckelii (Siluriformes: Auchenipteridae), with a contribution to Centromochlus definition

Neotrop. ichthyol; 18 (3), 2020
Historically, there are divergences in the species allocation between Centromochlus and Tatia. This study aimed to generate the first cytogenetic data about Centromochlus and, by analyzing a population of Centromochlus heckelii from the Amazon River basin, to contribute as evidence to a historical taxono...

Identification of Ten Long Noncoding RNAs as Biomarkers for Hepatocellular Carcinoma

Abstract Long-chain non-encoded RNAs (lncRNAs) are important in many life activities and can participate in the occurrence of hepatocellular carcinoma (HCC). Moreover, lncRNAs can be used as basis for developing new strategies to hinder liver cancer. To investigate the utility of lncRNAs in HCC as potent...

Genotyping of Low β -ODAP Grass Pea (Lathyrus sativus L. ) Germplasm with EST-SSR Markers

Abstract Grass pea (Lathyrus sativus L.) is an important protein source in arid regions as both human and animal food. Despite its significance, the use of grass pea is limited by the presence of β-N-oxalyl-L-a,b-diaminopropionic acid (β-ODAP) which can cause neurological disorders. Breeding st...

Rapid detection of Mycobacterium tuberculosis DNA and genetic markers for Isoniazid resistance in Ziehl-Neelsen stained slides

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Early diagnosis of tuberculosis (TB) and identification of strains of Mycobacterium tuberculosis resistant to anti-TB drugs are considered the main factors for disease control. OBJECTIVES To standardise a real-time polymerase chain reaction (qPCR) assay technique and apply it to identify mu...

Development of a small panel of SNPs to infer ancestry in Chileans that distinguishes Aymara and Mapuche components

Biol. Res; 53 (), 2020
BACKGROUND: Current South American populations trace their origins mainly to three continental ancestries, i.e. European, Amerindian and African. Individual variation in relative proportions of each of these ancestries may be confounded with socio-economic factors due to population stratification. Theref...
