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 ... -
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 ... -
Inhibitory effect of biofilm-forming Lactobacillus kunkeei strains against virulent Pseudomonas aeruginosa in vitro and in honeycomb moth (Galleria mellonella) infection model
(Chile. Universidad Mayor, 2017-11-10)Biofilms correspond to complex communities of microorganisms embedded in an extracellular polymeric matrix. Biofilm lifestyle predominates in Pseudomonas aeruginosa, an opportunistic Gram negative pathogen responsible for ... -
Inhibitory effect of serotype a of Aggregatibacter actinomycetemcomitans on the increased destructive potential of serotype b
(WILEY, 2020)Objective The serotype b of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) induces higher cytokine production in dendritic cells (DCs) compared with the other serotypes. However, this increased immunostimulatory ... -
Initial response of understorey vegetation and tree regeneration to a mixed-severity fire in old-growth Araucaria-Nothofagus forests
(WILEY, 2019)Questions Fire is a key factor influencing Araucaria araucana forests, but the impact of fire severity on the understorey vegetation is not well understood. In this study we seek to answer the following questions: (a) how ... -
Injury to the nervous system: A look into the ER
(CIENCIAS, 2016)Injury to the central or peripheral nervous systems leads to the loss of cognitive and/or sensorimotor capabilities that still lack an effective treatment. Although injury to the nervous system involves multiple and complex ... -
Insect abundance and damage on the deciduous Nothofagus macrocarpa increase with altitude at a site in the Mediterranean climate zone of Chile
(CIENCIAS, 2015)An understanding of the spatial and temporal patterns of insect abundance and plant damage across altitudinal gradients and the mechanisms driving them is limited. Importantly, little is known in this area in relation to ... -
