Development of a Portland Cement-Based Material with Agave salmiana Leaves Bioaggregate by Rosas Díaz, Felipe Esteban, García Hernández, David Gilberto, Mendoza Rangel, José Manuel, Terán Torres, Bernardo Tadeo, Galindo Rodríguez, Sergio Arturo, Juárez Alvarado, César Antonio

“…The objective of the research was to develop plant-based concretes with a matrix based on Portland cement and an aggregate of Agave salmiana (AS) leaves, obtained from the residues of the tequila industry that have no current purpose, as a total replacement for the calcareous aggregates commonly used in the manufacturing of mortars and whose extraction is associated with high levels of pollution, to improve their thermal properties and reduce the energy demand for air conditioning in homes. Characterization tests were carried out on the raw materials and the vegetal aggregate was processed to improve its compatibility with the cement paste through four different treatments: (a) freezing (T/C), (b) hornification (T/H), (c) sodium hydroxide (T/NaOH), and (d) solid paraffin (T/P). …”

Molecular epidemiology of coagulase-negative bloodstream isolates: detection of Staphylococcus epidermidis ST2, ST7 and linezolid-resistant ST23 by Martínez Meléndez, Adrián, Morfín Otero, Rayo, Villarreal Treviño, Licet, Camacho Ortiz, Adrián, González González, Gloria María, Llaca Díaz, Jorge Martín, Rodríguez Noriega, Eduardo, Garza González, Elvira

“…The mechanisms contributing to persistence of coagulase-negative staphylococci are diverse; to better understanding of their dynamics, the characterization of nosocomial isolates is needed. Our aim was to characterize phenotypic and molecular characteristics of Staphylococcus epidermidis and Staphylococcus haemolyticus human blood isolates from two tertiary care hospitals in Mexico, the Hospital Universitario in Monterrey and the Hospital Civil in Guadalajara. …”

Aluminosilicates as a Double-Edged Sword: Adsorption of Aflatoxin B1 and Sequestration of Essential Trace Minerals in an In Vitro Gastrointestinal Poultry Model by Hernández Martínez, Sara Paola, Delgado Cedeño, Armando, Ramos Zayas, Yareellys, Franco Molina, Moisés Armides, Méndez Zamora, Gerardo, Marroquín Cardona, Alicia Guadalupe, Kawas Garza, Jorge R.

“…In this study, four clays, three smectites (C-1, C-2, and C-3), and one zeolite (C-4), were compared as adsorbents of AFB1 and trace inorganic nutrients using an in vitro gastrointestinal model for poultry. Characterization of the clays using Fourier transform infrared spectroscopy revealed characteristic bands of smectites in C-1, C-2, and C-3 (stretching vibrations of Si-O, Al-O-Si, and Si-O-Si). …”

Investigating the cryptogenic status of the sea squirt Didemnum perlucidum (Tunicata, Ascidiacea) in Australia based on a molecular study of its global distribution by Dias, Joana, Rocha, Rosana, Godwin, Scott, Tovar Hernández, María Ana, Delahoz, Maria, McKirdy, Simon, De Lestang, Paul, McDonald, Justin, Snow, Michael

“…The current study was initiated to review the current known global geographic range of D. perlucidum and to obtain specimens that could support molecular studies aimed at evaluating the potential origin of this species in Australia. Characterization of 5’ COI mitochondrial sequences from 286 specimens revealed a remarkably low level of genetic diversity across the current known range of D. perlucidum and the existence of one main widespread genetic haplotype. …”
