A global metagenomic map of urban microbiomes and antimicrobial resistance
(CELL PRESS, 2021-06-24)We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an ... -
A HaloTag-TEV genetic cassette for mechanical phenotyping of proteins from tissues
(Nature Publishing Group, 2020-04-28)Single-molecule methods using recombinant proteins have generated transformative hypotheses on how mechanical forces are generated and sensed in biological tissues. However, testing these mechanical hypotheses on proteins ... -
A highly stable black phosphorene nanocomposite for voltammetric detection of clenbuterol
(SPRINGER WIEN, 2018)A nanocomposite was prepared from graphene-like two-dimensional black phosphorene (BP, an allotrope of phosphorus) and nafion (Nf) treated with isopropanol (IP). A glassy carbon electrode (GCE) modified with this nanocomposite ... -
A mechanistic approach for the optimization of loperamide loaded nanocarriers characterization: Diafiltration and mathematical modeling advantages
(ELSEVIER SCIENCE BV, 2018)Oral bioavailability of loperamide is restricted by its limited absorption in the gastrointestinal tract due to its poor aqueous solubility and its P-glycoprotein (Pgp) substrate characteristic. In addition, ammonium ... -
A Meta-Analytical Comparison of the Effects of Small-Sided Games vs. Running-Based High-Intensity Interval Training on Soccer Players' Repeated-Sprint Ability
(MDPI, 2021-04-01)This systematic review with a meta-analysis was conducted to compare the effects of small-sided games (SSGs)-based interventions with the effects of running-based high-intensity interval training (HIIT) interventions on ... -
A method to deconvolve stellar profiles The non-rotating line utilizing Gaussian sum approximation
(EDP SCIENCES S A, 2023-08-04)Context. Currently, one of the standard procedures used to determine stellar and wind parameters of massive stars involves to comparing the observed spectral lines with a grid of synthetic lines. These synthetic lines are ... -
A Metholodological Proposal for Using Poetry in the English as a Foreign Language Classroom
(Chile. Universidad Mayor, 2019)Abstract: The following essay aims to invite English as a foreign or second language teachers to include poetry in their classes as an alternative technique that might cause a positive impact in their students’ ... -
A Monte Carlo code for the collisional evolution of porous aggregates (CPA)
(EDP SCIENCES S A, 2023-03-29)Context. The collisional evolution of submillimeter-sized porous dust aggregates is important in many astrophysical fields.Aims. We have developed a Monte Carlo code to study the processes of collision between mass-asymmetric, ... -
