Los sentidos en las artes y las culturas expresivas de Chile. Usos del olfato y la escucha para una reescritura histórica de la colonialidad
(Argentina. Universidad Nacional de Mar del Plata. Facultad de Humanidades. Centro de Estudios Históricos (CEHis), 2019)Este artículo recurre a un enfoque sensorial para analizar prácticas expresivas como la pintura, la cerámica y la música a fin de comprender las formas de imaginar el territorio colonial chileno. Al mismo tiempo, indaga ... -
Sequential epidemic-like spread between agglomerates of self-propelled agents in one dimension
(American Physical Society, 2023-10-02)Motile organisms can form stable agglomerates such as cities or colonies. In the outbreak of a highly contagious disease, the control of large-scale epidemic spread depends on factors like the number and size of agglomerates, ... -

(Universidad de Concepción. Facultad de Enfermería, 2022-03)En Chile, la sequía ha afectado a la población social y económicamente vulnerable, impactando desfavorablemente en los determinantes sociales, salud y calidad de vida. Objetivo: Visibilizar los efectos de la sequía de una ... -
Serine 25 phosphorylation inhibits RIPK1 kinase-dependent cell death in models of infection and inflammation
(NATURE PUBLISHING GROUP, 2019)RIPK1 regulates cell death and inflammation through kinase-dependent and -independent mechanisms. As a scaffold, RIPK1 inhibits caspase-8-dependent apoptosis and RIPK3/MLKL-dependent necroptosis. As a kinase, RIPK1 ... -
Severe alterations in expression and localisation of alpha 6 beta 4 integrin in salivary gland acini from patients with Sjogren syndrome
(CIENCIAS, 2009)Objectives: In salivary glands from patients with Sjogren syndrome, overexpression of laminins 1 and 5 and disorganisation of the acinar basal lamina have been reported. Laminin 5 mediates association of the basal lamina ... -
Severe spontaneous cases of bisphosphonate-related osteonecrosis of the jaws
(CIENCIAS, 2007)A new kind of osteonecrosis has been reported, first in connection with chemotherapy and later with bisphosphonate therapy. Bisphosphonates are used as adjunctive therapy with patients suffering from cancer. The connection ... -
Sex differences in nonmedical prescription tranquilizer and stimulant use trends among secondary school students in Argentina, Chile, and Uruguay
(ELSEVIER IRELAND LTD, 2019)Background Little is known about recent nonmedical prescription tranquilizer and stimulant use trends in Latin America. We tested whether recent trends among students in three South American countries differed by sex over ... -
SGSI support throught malware's classification using a pattern analysis
(IEEE, 2016)Nowadays, there are significant amounts of malware codes that are created every day. However, the majority of these samples (malware) are variations of other malware that have been already identified. Therefore, most of ... -
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
(Elsevier, 2020-11)The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ... -
Short timescale dynamics of phytoplankton in Fildes Bay, Antarctica
(CAMBRIDGE UNIV PRESS, 2017)Phytoplankton is responsible for most primary production in Antarctica, but the short timescale dynamics of its size structure and composition are poorly described and understood. The abundance and composition of phytoplankton ... -
Short- and Long-term Survival after Stroke in Hospitalized Patients in Chile: A Nationwide 5-Year Study
(CIENCIAS, 2013)Background: Short- and long-term stroke survival is a key indicator of hospital performance in stroke care. Our aim was to estimate short-and long-term survival rates in discharged patients diagnosed with ischemic stroke ... -
Short-term effects of variable-density thinning on regeneration in hardwood-dominated temperate rainforests
(Chile. Universidad Mayor, 2020-05)Second-growth temperate forests usually have simpler composition and structure than comparable old-growth stands. We evaluated the application of variable density thinning (VDT) as a way to increase old-growth attributes, ... -
Short-term response of soil microorganisms, nutrients and plant recovery in fire-affected Araucaria araucana forests
(ELSEVIER SCIENCE BV, 2018)Soil contains a wide variety of microorganisms that are responsible for fundamental ecological processes. However, increased frequency and severity of fires reduce microbial diversity and alter soil nutrient availability, ... -
Shrinkage Bubbles: The C-O-H-S Magmatic Fluid System at San Cristobal Volcano
(OXFORD UNIV PRESS, 2018)New analytical results for the composition of shrinkage bubbles (0.9-7.0 vol. %) in olivine-hosted (Fo <80%) primary melt inclusions (MIs) have been incorporated into a novel geochemical model for San Cristobal volcano, ... -
Shrub influences on seedling performance when restoring the slow-growing conifer Pilgerodendron uviferum in southern bog forests
(WILEY, 2020)Forest restoration is most efficient if it can take advantage of facilitative interactions between established vegetation and planted trees. However, positive and negative interactions have been identified in a number of ... -
Signal peptide recognition in Trypanosoma cruzi GP82 adhesin relies on its localization at protein N-terminus
(NATURE PUBLISHING GROUP, 2019)Trypanosoma cruzi, the causative agent of Chagas disease, has a dense coat of GPI-anchored virulence factors. T. cruzi GPI-anchored adhesin GP82 is encoded by a repertoire of transcripts containing several in-frame initiation ... -
Silencing of one copy of the translation initiation factor eIFiso4G in Japanese plum (Prunus salicina) impacts susceptibility to Plum pox virus (PPV) and small RNA production
(BMC, 2019)Background In plants, host factors encoded by susceptibility (S) genes are indispensable for viral infection. Resistance is achieved through the impairment or the absence of those susceptibility factors. Many S genes have ... -
