Research ArticleOpen accessIn the author namesIsoquinoline Alkaloids and the Ionophore Monensin Supplemented Alone or Combined on Ruminal Fermentation and Nutrient Digestibility in Steers Fed a High-Energy DietJesús D. Urías-Estrada, Beatriz I. Castro-Pérez, Alfredo Estrada-Angulo et al.The aim of this experiment was to investigate the Influence of Alkaloids (IQA) and sodium Monensin (MON) supplementation on characteristics of ruminal fermentation, microbial protein synthesis and site and extend of digestion. For this, 4 cannulated steers were used in a 4×4 Latin square design. Treatments consisted of a high-energy basal diet supplemented with: (1) No additive (Control), (2) 15 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 7 Oct 2021 · 6,580 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEcophysiology of Chirostoma Jordani Pisces: Atherinopsidae. Habitat Characterization and Population Dynamics in a Periurban Lake (Xochimilco, México)Latournerié-Cervera José Román, Rangel-Nambo María Isabel, Alma Rosa Estrada-OrtegaChirostoma Jordani is an endemic species of the Mexican plateau, whose population, due to anthropogenic causes, has experienced a notable decrease from 2000 to the present, putting its permanence in its natural habitat at risk. Therefore, the objectives of this research were focused on evaluating the population dynamics of C. Jordani through its size and weight distributions and growth rate … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Jan 2021 · 7,546 accessesView PDF Cite

Research ArticleOpen accessIn the author namesGenotoxicity through Exposure to Particulate Matter (PM10) at two Sites in the Valle de Aburrá, ColombiaVerónica Estrada-Vélez, Lucelly López-López, Lina María Martínez-Sánchez et al.To establish differences in the genotoxic effect of particulate matter (PM10) in exposed individuals at two sites in the Valle de Aburrá (VA). This was a descriptive cross-sectional study of 2 groups of individuals exposed to 67.7 and 45 µg/m3 of PM10 for a minimum of 8 hours/day. The frequency of Chromosomal Abnormalities (CAs) and the mitotic index were evaluated … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 19 Mar 2019 · 8,368 accessesView PDF Cite

Research ArticleOpen accessIn the author namesStatistical Size and Power of Eight Normality Tests in Presence of GARCH (1 1) ErrorsJulio César Alonso, Daniela EstradaIn this work, we assess the power and size of eight normality tests underthe assumption that errors follow a GARCH (1, 1) process by using MonteCarlo simulations. Four results stand out. First, the presence of a GARCH(1, 1) process increases the probability of making type I error. Second, Pearsonnormality test is recommended if it is assumed that errors follow a … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 11 Feb 2019 · 6,992 accessesView PDF Cite

Research ArticleOpen accessIn the author namesNovel D-Galactose Isomerases from Lactobacillus Strains Isolated from the Sweet Sap of Agave atrovirensMaría Miriam Hernández-Arroyo, Miguel Ángel Plascencia-Espinosa, María Eugenia Hidalgo-Lara et al.D-tagatose is a natural monosaccharide used as a low-calorie sugar substitute in food, beverage and pharmaceutical products. Although it is a rare sugar, it can manufacture by enzymatic isomerization of D-galactose Isomerase (D-GI). In this study, a screening was carried out to search microorganism producing D-GI in aguamiel. A rich selective medium was used in arabinose extracted from gum arabic. … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 11 Dec 2018 · 10,238 accessesView PDF Cite
