Influence of lipopolysaccharide outer-core in the intrinsic resistance to antimicrobial peptides and virulence in Edwardsiella ictaluri
(CIENCIAS, 2016)The genus Edwardsiella consists of bacteria with an intrinsic resistance to cyclic cationic antimicrobial peptides (CAMPs). Edwardsiella ictaluri, a pathogen of the catfish (Ictalurus punctatus) and the causative agent of ... -
Influence of mobile genetic elements and insertion sequences in long- and short-term adaptive processes of Acidithiobacillus ferrooxidans strains
(NATURE PORTFOLIO, 2023-07-05)The recent revision of the Acidithiobacillia class using genomic taxonomy methods has shown that, in addition to the existence of previously unrecognized genera and species, some species of the class harbor levels of ... -
Influence of porosity on high-velocity mass-asymmetric collisions
(OXFORD UNIV PRESS, 2020)Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ... -
Influence of Porosity on the Elastic Modulus of Ti-Zr-Ta-Nb Foams with a Low Nb Content
(MDPI, 2019)The development of titanium foams with a low elastic modulus has increased their scientific and technological relevance due to the evident need to avoid stress shielding problems. In this work, we studied the synthesis and ... -
Influence of squeezing on the weak-to-strong measurement transition
(AMER PHYSICAL SOC, 2021-06-11)In this work, we study the measurement transition for a coherent squeezed pointer state through a transition factor Gamma that involves a system-pointer coupling by using an arbitrary measured observable A. In addition, ... -
Influence of the concentration of copper nanoparticles on the thermo-mechanical and antibacterial properties of nanocomposites based on poly(butylene adipate-co-terephthalate)
(WILEY, 2019)Poly(butylene adipate-co-terephthalate) (PBAT) was mixed with copper nanoparticles (Cu-NPs) in concentrations of 1%, 3%, and 5% with particle size between 100 nm and 200 nm by the melting method. A morphological, thermal, ... -
Influence of the Electrolyte Salt on the Electrochemical Polymerization of Pyrrole. Effects on p-Doping/Undoping, Conductivity and Morphology
(ESG, 2018)The relationship between the p-doping/undoping process (charge, stability and reversibility) and the nucleation and growth mechanisms concerning the influence of the type of electrochemical perturbation of the system during ... -

(Ediciones Doyma, S.L., 2020-03)Introducción: El desarrollo de nuevas estrategias y herramientas de trabajo que permitan optimizar el tiempo de recuperación tras una lesión o incrementar el rendimiento deportivo de los atletas, ha llevado a explorar ... -
La Influencia del Control Preventivo en el Diseño Normativo del Régimen Presidencial Chileno. Anuario Iberoamericano de Justicia Constitucional
(Facultad de Humanidades, 2017)El presente trabajo aborda el Tribunal Constitucional chileno (TC) en su contexto histórico y doctrinal, de manera tal de comprender el sentido y alcance del control preventivo de constitucionalidad de las leyes en el ... -
La inhibición de los puntos de control inmunológico, una terapia en evolución: remembranza del Premio Nobel de Medicina 2018
(Chile. Universidad Mayor, 2022-01)Professors James P. Allison and Tasuku Honjo were awarded with the 2018 Nobel Prize in Medicine for their contributions in cancer immunotherapy. The latter is a breakthrough in cancer therapy, aimed to overcome tumor-induced ... -
Inhibition of InsP3R with Xestospongin B Reduces Mitochondrial Respiration and Induces Selective Cell Death in T Cell Acute Lymphoblastic Leukemia Cells
(MDPI, 2021-01)T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy whose chemoresistance and relapse persist as a problem despite significant advances in its chemotherapeutic treatments. Mitochondrial ... -
Inhibition of miR-378a-3p by Inflammation Enhances IL-33 Levels: A Novel Mechanism of Alarmin Modulation in Ulcerative Colitis
(FRONTIERS MEDIA SA, 2019)Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by mucosa damage associated with an uncontrolled inflammatory response. This immunological impairment leads to altered inflammatory mediators ... -
Inhibition-Disruption of Candida glabrata Biofilms: Symmetrical Selenoesters as Potential Anti-Biofilm Agents
(MDPI, 2019)Candida glabrata is one of the most prevalent pathogenic Candida species in dental plaque on tooth surfaces. Candida biofilms exhibit an enhanced resistance against most antifungal agents. Thus, the development of alternative ... -
