Identificación del alelo HLA B*57: 01 en una población militar, de Lima-Perú

Rev. chil. infectol; 41 (2), 2024
El alelo HLA B*57:01 es un marcador genético asociado con la hipersensibilidad al fármaco anti-retroviral abacavir (ABC) y su frecuencia en la población peruana todavía es desconocida. El objetivo fue identificar el alelo HLA B*57:01 en una población militar de Lima, Perú. Se reclutaron 43 personas...

Frequência alélica e potencial regulatório de polimorfismosno gene NELL1 em uma população da Bahia – Brasil

Introdução: o gene NELL1 codifica a proteína semelhante ao fator de crescimento epidérmico (do inglês Epidermal Growth factor (EGF)-like). GWASs e estudos de associação com genes candidatos têm sido utilizados para estabelecer a conexão entre polimorfismos de nucleotídeo único (SNP) no NEL...

Behavior of the Genetic Markers at Screening during the First Trimester of Pregnancy in Euploid Fetuses

Abstract Objective This study aims to describe the behavior of chromosomopathy screenings in euploid fetuses. Methods This is a prospective descriptive study with 566 patients at 11 to 14 weeks of gestation. The associations between ultrasound scans and serological variables were studied. For the quant...

Genetic variability of Sargassum liebmannii on the coast of Jalisco in the central Mexican Pacific revealed by molecular markers and morphological traits

BACKGROUND Sargassum liebmannii is widely distributed throughout rocky, coastal upwelling areas in the tropical Mexican Pacific. This brown algae is of great environmental and industrial importance. However, no information is available that documents the genetic or phenotypic variability of the species, ...

DD Genotype and Atherosclerosis in Overweight Menopausal Women

Abstract Background Sex-specific pathology of coronary artery disease (CAD) has not been recognized. Women with obstructive or nonobstructive CAD associated with traditional risk factors have similar events; no studies have explored both populations in association with genetic markers. Objective To e...

Análisis genético de cinco polimorfismos de nucleótido simple de caseínas lácteas obtenidos con chips genómicos en ganado Holstein de Antioquia, Colombia

Rev. med. vet. zoot; 68 (2), 2021
RESUMEN Los polimorfismos genéticos asociados con las caseínas de la leche son de gran importancia, ya que pueden ser usados como marcadores genéticos para mejorar el rendimiento productivo en los hatos lecheros. El objetivo de este estudio fue evaluar la diversidad y estructura genética de 5 SNP de ...

Differential expression patterns of myogenic regulatory factors in the postnatal longissimus dorsi muscle of Jeju Native Pig and Berkshire breeds along with their co-expression with Pax7

BACKGROUND: Myogenic regulatory factors (MRFs) such as MyoD, Myf6 and Myf5 play a vital role in the growth and development of muscles. Jeju Native Pig (JNP) is the top ranker in Korea amongst the indigenous livestock reared for meat purpose. Few studies covering transcript abundance of the MRFs and relat...

Hepatic mitochondria in diet-induced obese mice (stereology and molecular analysis)

Int. j. morphol; 39 (2), 2021
SUMMARY: The world population is going through an obesity epidemic that has severe consequences for the health system. This study focused on studying hepatic mitochondria in obese animals induced by a high-fat (HF) diet and used the model-based stereology in electron micrographs for the quantitative stud...

Genetic markers for preeclampsia in Peruvian women

Colomb. med; 52 (1), 2021
Abstract Background: Preeclampsia is a multiorgan disorder associated with maternal and perinatal morbi-mortality. In Peru, incidence is 10% and accounts for 22% of maternal deaths. Genome and genetic epidemiological studies have found an association between preeclampsia and genetic polymorphisms. Obj...
