Description of a novel variant in the MAMLD1 gene in isolated hypospadias

Urol. colomb; 27 (1), 2018
Introduction Hypospadias is a multifactorial malformation. Among previously described genes, the MAMLD1 has recently been identified in association with the development of hypospadias. So far, there are no studies in Latin America addressing this gene. The aim of this paper is to describe the presence ...

Proteins functionalization: a strategy that boost the performance of these macromolecules for innovative pharmaceutical and food developments

Vitae (Medellín); 25 (1), 2018
Proteins are macromolecules exhibiting amphiphilic properties, good biocompatibility, biodegradability, high nutritional value, and show strong interactions with several types of active compounds via hydrogen bonding and electrostatic interactions (1). These plant or animal-derived macromolecules differ ...

Insect cuticle: a critical determinant of insecticide resistance

Intense use of insecticides has resulted in the selection of extreme levels of resistance in insect populations. Therefore understanding the molecular basis of insecticide resistance mechanisms becomes critical. Penetration resistance refers to modifications in the cuticle that will eventually slow down ...

Proteínas Totales, Fosfatasa Alcalina, Prostaglandinas E2 y Lisozima como Biomarcadores Salivales en Pacientes Adultos con Periodontitis Crónica

RESUMEN: La periodontitis crónica es una inflamación de los tejidos que rodean y dan soporte a los dientes. Diversos biomarcadores químicos y pro inflamatorios están aumentados durante el transcurso de la enfermedad. El objetivo del estudio fue determinar los distintos niveles salivales de proteínas...

Um caso de alergia a romã e a noz – qual o papel da proteína de transferência lipídica Pru p 3?

As proteínas de transferência lipídica (LTPs) são pan-alergênios responsáveis pela reatividade cruzada entre frutos, vegetais e polens. A Pru p 3 (LTP presente no pêssego) é reconhecida como marcador de gravidade na alergia alimentar. A romã e a noz são frutos relatados como causas de reações...

Fortifying pork liver mixture: Evaluation of protein quality and iron bioavailability - Part 2

Rev. Nutr. (Online); 30 (6), 2017
ABSTRACT Objective To evaluate the protein quality and iron bioavailability of a fortifying mixture based on pork liver. Methods Determinations of protein efficiency ratio, net protein utilization, true digestibility and hemoglobin regeneration efficiency by depletion and repletion were performed. In t...

Tracing the origin of the NS1 A188V substitution responsible for recent enhancement of Zika virus Asian genotype infectivity

Mem. Inst. Oswaldo Cruz; 112 (11), 2017
A recent study showed that infectivity of Zika virus (ZIKV) Asian genotype was enhanced by an alanine-to-valine amino acid substitution at residue 188 of the NS1 protein, but the precise time and location of origin of this mutation were not formally estimated. Here, we applied a Bayesian coalescent-based...

Evaluación del aporte nutricional del amaranto (amaranthus caudatus linnaeus), quinua (chenopodium quinoa willd) y tarwi (lupinus mutabilis sweet) en el desayuno

Con-ciencia (La Paz); 5 (2), 2017
El amaranto, quinua y tarwi, son alimentos (cereales) de gran valor nutritivo y medicinal, consecuentemente es importante estudiar estas propiedades para el beneficio en la calidad de la alimentación (por su contenido en macronutrientes) como para la prevención de enfermedades. El desayuno como primera...

Mitochondrial proteomic profile of complex IV deficiency fibroblasts: rearrangement of oxidative phosphorylation complex/supercomplex and other metabolic pathways

Abstract: Background: Mitochondriopathies are multisystem diseases affecting the oxidative phosphorylation (OXPHOS) system. Skin fibroblasts are a good model for the study of these diseases. Fibroblasts with a complex IV mitochondriopathy were used to determine the molecular mechanism and the main affe...

Proteomic changes in a childhood acute lymphoblastic leukemia cell line during the adaptation to vincristine

Abstract: Introduction: Relapse occurs in approximately 20% of Mexican patients with childhood acute lymphoblastic leukemia (ALL). In this group, chemoresistance may be one of the biggest challenges. An overview of complex cellular processes like drug tolerance can be achieved with proteomic studies. ...
