(Frontiers Media S.A., 2020-08)Nicotinamide (vitamin B3) is a key component in the cellular production of Nicotinamide Adenine Dinucleotide (NAD) and has long been associated with neuronal development, survival and death. Numerous data suggest that ... -
Non-Specific Antibodies Induce Lysosomal Activation in Atlantic Salmon Macrophages Infected by Piscirickettsia salmonis
(Frontiers Media S.A., 2020-11)Piscirickettsia salmonis, an aggressive intracellular pathogen, is the etiological agent of salmonid rickettsial septicemia (SRS). This is a chronic multisystemic disease that generates high mortalities and large losses ... -
Perception and legitimation in the face of socioecological inequalities in contemporary Chile
(Latin American Studies Association, 2020)This article analyzes the perceptions about and legitimation of inequalities in the case of Chile, focusing on the socioecological dimension. It shows the results of a four-year qualitative study carried out in five cases ... -
In vitropropagation ofLeptocarpha rivularis, a native medicinal plant
(Springer New York, 2020-12)Leptocarpha rivularis, commonly known as "palo negro", is a species of the Astereaceae family, endemic in the forests of Southern Chile. The extracts of this plant have medicinal properties attributable to its secondary ... -
Implications of Selective Autophagy Dysfunction for ALS Pathology
(MDPI Multidisciplinary Digital Publishing Institute, 2020-02)Amyotrophic lateral sclerosis (ALS) is a lethal neurodegenerative disorder that progressively affects motor neurons in the brain and spinal cord. Due to the biological complexity of the disease, its etiology remains unknown. ... -
Idiopathic inflammatory myopathy human derived cells retain their ability to increase mitochondrial function
(Public Library of Science, 2020-11)Idiopathic Inflammatory Myopathies (IIMs) have been studied within the framework of autoimmune diseases where skeletal muscle appears to have a passive role in the illness. However, persiting weakness even after resolving ... -
Identification of Metabolite and Lipid Profiles in a Segregating Peach Population Associated with Mealiness in Prunus persica (L.) Batsch
(MDPI Multidisciplinary Digital Publishing Institute, 2020-04)The peach is the third most important temperate fruit crop considering fruit production and harvested area in the world. Exporting peaches represents a challenge due to the long-distance nature of export markets. This ... -
Highly porous tungsten for plasma-facing applications in nuclear fusion power plants: a computational analysis of hollow nanoparticles
(IOP Publishing Ltd., 2020-09)Plasma-facing materials (PFMs) for nuclear fusion, either in inertial confinement fusion (ICF) or in magnetic confinement fusion (MCF) approaches, must withstand extremely hostile irradiation conditions. Mitigation strategies ... -
Numerical skills and dyscalculia. From basic research to practice in Cuba
(Taylor and Francis Ltd., 2020-06)Establishing bridges between the findings from cognitive neurosciences and teaching practice has not been systematically achieved. However, many researchers interested in this area agree on the positive impact that knowledge ... -
¿Lobo o lóbulo? Una explicación desde el origen etimológico: propuesta para terminología anatómica
(Universidad de La Frontera, 2020-08)During the Renaissance anatomists laid the foundations for present day knowledge in this discipline. Not all anatomists however, were good linguists, which led to errors in translation and prompted discussions in reference ... -
