Cell death induced by mitochondrial complex I inhibition is mediated by Iron Regulatory Protein
(Elsevier, 2017)Mitochondrial dysfunction and oxidative damage, often accompanied by elevated intracellular iron levels, are pathophysiological features in a number of neurodegenerative processes. The question arises as to whether ... -
Completely decomposable Jacobian varieties in new genera
(Taylor & Francis, 2017)We present a new technique to study Jacobian variety decompositions using subgroups of the automorphism group of the curve and the corresponding intermediate covers. In particular, this new method allows us to produce many ... -
A CLCA regulatory protein present in the chemosensory cilia of olfactory sensory neurons induces a Ca2+ -activated Cl- current when transfected into HEK293
(BIOMED Central Ltd., 2017)Background: CLCA is a family of metalloproteases that regulate Ca2+-activated Cl- fluxes in epithelial tissues. In HEK293 cells, CLCA1 promotes membrane expression of an endogenous Anoctamin 1 (ANO1, also termed ... -
Birefringent light propagation on anisotropic cosmological backgrounds
(American Physical Society, 2017)Exact electromagnetic wave solutions to Maxwell equations on anisotropic Bianchi I cosmological spacetime backgrounds are studied. The waves evolving on Bianchi I spacetimes exhibit birefringence (associated with linear ... -
Quasi-isothermal DSC testing of epoxy adhesives using initial fast heating rates
(Wiley, 2017)Three major factors decrease the accuracy of the cure measurement in standard-isothermal testing using differential scanning calorimetry (DSC). First, cure occurs during the heating step. Second, data are lost during the ... -
Theoretical insights into the regioselectivity of a Pictet-Spengler reaction: transition state structures leading to salsolinol and isosalsolinol
(Wiley, 2017)The mechanism of the cyclization step of the Pictet-Spengler reaction between acetaldehyde and dopamine to give salsolinol and isosalsolinol was studied computationally, using density functional theory. The preferential ... -
Linear kinetic waves in plasmas described by Kappa Distributions
(Elsevier, 2017)In this chapter we present an overview of the excitation, propagation, and absorption of linear plasma waves in collisionless, spatially uniform, multicomponent, magnetized non-Maxwellian plasma characterized by a ... -
Single and combined effect of retinoic acid and rapamycin modulate the generation, activity and homing potential of induced human regulatory T cells
(Public Library Science, 2017)Adoptive transfer of CD4+CD25+FOXP3+ regulatory T cells (Treg cells) has been successfully utilized to treat graft versus host disease and represents a promising strategy for the treatment of autoimmune diseases and ... -
Novel therapies targeting cardioprotection and regeneration
(Bentham Science Publishers, 2017)Cardiovascular disease is the leading cause of death worldwide. The heart is susceptible to pathologies that impact the myocardium directly, such as myocardial infarction and consequent heart failure, as well as conditions ... -
A short hairpin RNA-based adjuvant targeting NF-kappa B repressor I kappa B alpha promotes migration of dermal dendritic cells to draining lymph nodes and antitumor CTL responses induced by DNA vaccination
(Elsevier, 2017)DNA vaccination is an attractive approach to elicit tumor-specific cytotoxic CD8(+) T lymphocytes (CTL), which can mediate protective immunity against tumors. To initiate CTL responses, antigen-encoding plasmids employed ... -
Morphological and taxonomic descriptions of a new genus and species of killifishes (Teleostei: Cyprinodontiformes) from the high Andes of northern Chile
(Public Library Science, 2017)A new genus and species, Pseudorestias lirimensis, is described from the southern part of the Chilean Altiplano. While sharing several characters that clearly align the new species with Orestias, this new fish is characterized ... -
Genetic and morphological evidence for a new cryptic species of Ectinogonia (Coleoptera: Buprestidae) from central Chile
(Magnolia Press, 2017)The genus Ectinogonia Spinola, 1837 is a genus mainly found in Chile; it currently contains 17 species. Recent exploration in the Andes Mountain Range of the Bio Bio Region in Chile have resulted in the collection of ... -
Adoptive transfer of autoimmune splenic dendritic cells to lupus-prone mice triggers a B lymphocyte humoral response
(Springer, 2017)Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by increased autoantibody production that leads to multiple tissue injuries. Dendritic cells (DCs) are important orchestrators of immune responses ... -
Pollinators and crossability as reproductive isolation barriers in two sympatric oil rewarding Calceolaria (Calceolariaceae) species
(Springer, 2017)Pollinator species are widely accepted as an important factor in plant reproductive isolation. Although mostly investigated in plants visited by different groups of pollinators (e.g., hummingbirds vs bees), few studies ... -
La plasticidad fenotípica no explica diferencias inter-cuencas en las respuestas conductuales de Smicridea annulicornis a la conductividad eléctrica del agua
(Universidad de Chile, 2018-04)En Chile los ríos presentan alta variabilidad ambiental en la conductividad, este parámetro es un estresor de los organismos acuáticos y sirve para estimar el grado de perturbación de los ríos. Los efectos de la conductividad ... -
Síntesis de un catalizador soportado en monolito cerámico y determinación de su actividad para el abatimiento de CO y NO desde la combustión de biomasa para calefacción
(Universidad de Chile, 2018-05)Al considerar la matriz energética de Chile, la combustión de biomasa es especialmente relevante al sur del país, específicamente entre las regiones de O`Higgins y Aysén, donde se estima que el 74% de los hogares utilizan ... -
Identificación de compuestos cuticulares mediante GC-MS y su rol en colonias de Neotermes chilensis (Blattodea: Kalotermitidae)
(Universidad de Chile, 2018)En insectos eusociales, el reconocimiento y la comunicación entre compañeros de nido soportan la estructura social de la colonia. Estas conclusiones se basan más en estudios en himenópteros que en termitas (Blattodea). En ... -
Desarrollo de sondas acopladas a Quantum dots para analizar la localización subcelular del ARN genómico de VIH-1 mediante microscopía confocal
(Universidad de Chile, 2018)Los mecanismos involucrados en el control post-transcripcional del ciclo replicativo del Virus de la Inmunodeficiencia Humana (VIH), específicamente los eventos moleculares que permiten la interacción del ARN genómico ... -
Early life experience drives short term acclimation of metabolic and osmoregulatory traits in the leaf eared mouse
