Resumen Introducción: La identificación de portadores del virus de la hepatitis B en donantes de sangre es imperativo para evitar la transmisión de la enfermedad a través de transfusiones sanguíneas. Objetivo: Determinar si los donantes de sangre con resultados positivos de los marcadores serológ...

Resumen Introducción: El virus de la Hepatitis E (HVE) es de ácido ribonucleico desnudo, los genotipos 3 y 4 pueden presentarse como una zoonosis transmitida por agua o alimentos contaminados. En la zona del eje cafetero-Colombia, no se ha descrito la presencia de anticuerpos para este virus en la co...
Abstract: Endocan, a 50 kDa soluble proteoglycan, also called endothelial cell-specific molecule-1 (ESM-1), is involved in many major cellular activities and has been reported to be overexpressed in inflammatory conditions. This study aims to determine ESM-1 levels in gingival crevicular fluid (GCF) samp...
Toxoplasmosis is a zoonosis of reproductive nature that is transmitted to humans mainly by ingestion of undercooked meat or drinking oocyte-contaminated water. The slaughter of small ruminants in clandestine slaughterhouses and the presence of companion animals in these locations may be epidemiologically...

Abstract Objective: To determine the level of biofilm formation of S. mutans after being exposed to 5% sucrose, 8% lactose, or 1% xylitol. Material and Methods: This research was a laboratory-based experimental study with post-test only control group design. S. mutans was grown in test tubes containing...
O Plasmodium vivax é a espécie com maior distribuição geográfica no mundo e a que predomina nas Américas, incluindo o Brasil. Comparado ao Plasmodium falciparum, poucas vacinas contra o P. vivax encontram-se em fase de testes clínicos. Um dos antígenos de formas sanguíneas de P. vivax candidato ...

BACKGROUND Dogs are the main peridomiciliary reservoir of Leishmania infantum thus the correct diagnosis of infection is essential for the control of the transmission and treatment as well. However, the diagnosis is based on serological assays that are not fully effective. OBJECTIVE We aimed to establ...

ABSTRACT Objective: To compare Transforming growth factor-β1 (TGF-β1) expression in various L-PRF concentrations on the hDPSC differentiation process. Material and Methods: hDPSC cell cultures were subjected to serum starvation by reducing FBS levels in the hDPSC culture media. Lysate PRF was...
ABSTRACT Strongyloidiasis is a helminthiasis of neglected condition that has no gold standard parasitological diagnosis due to the intermittent release of larvae in feces. This study aimed to use an scFv (single chain variable fragment) obtained by Phage Display, previously validated to detect immune com...
The methanolic extract of Buchholzia coriacea seeds (MEBC) has been reported to induce male reproductive toxicity by decreasing sperm parameters and fertility index. To elucidate the possible mechanism(s), the effects of graded doses of MEBC on sex hormones and sperm profile were investigated in this stu...
