STRATEGy Seismic neTwoRk/Array in norThwEstern arGentina: Study of the 2015 El Galpón earthquake and its aftershock sequence
After a damaging, medium-sized earthquake (Mw 5.8; October 17, 2015) in El Galpón area in the Salta Province, we installed a local seismological network around the estimated epicenter covering also remarkable tectonic and geological orographic structures. The 2015 earthquake took place in the Andean foreland at about 17km depth. The so called Santa Bárbara System is the easternmost morphostructural region of the central Andes. As a part of the broken foreland it is bounded to the north by the Subandean Belt and the Sierras Pampeanas lying in the south; to the east joins the Chaco-Paraná basin.Eje: Estudio del Interior Terrestre.Facultad de Ciencias Astronómicas y Geofísica

New records of myxomycetes for Central America and comments on their regional distribution
Several studies on myxomycetes in Central America during the last decade have greatly increased the
information on the morphological species present in the different countries of that region. Herein we present a
list of 71 new records compiled for four different countries in Central America including 37, 23, 19 and 9
unreported species for Panama, El Salvador, Honduras and Costa Rica, respectively. This newly available
information was collected by all authors in different field surveys across the region. Results showed that, as
information became available, the distribution of most species extended across Central America, as expected
from an ecological point of view. The present effort is an important contribution for the development of baseline
data on myxomycete fruiting bodies in Central America for biological monitoring in the context of adverse
ecological processes and potential negative effects of climate change on microbial biodiversity.Universidad de Costa Rica/[731-B5-062]/UCR/Costa RicaUniversidad de Costa Rica/[731-B7-717]/UCR/Costa RicaUniversidad de Costa Rica/[731-A0-826]/UCR/Costa RicaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ingeniería::Instituto Investigaciones en Ingeniería (INII
La paleodieta de cinco especies de mamíferos herbívoros rancholabreanos de valsequillo (Puebla, México)
Through the use of the 13C/12C and 18O/16O isotopic relationships found at enamel and osteodentine, here it is inferred the diet and preferred habitat in which five extinct herbivore species from the Late Pleistocene of Valsequillo, Puebla, México. The horses, mammoths, and sloths showed a diet mainly based in C4, meanwhile the capybaraand gomphotheres were mixed C3/C4 feeders. The vegetation in which those animals lived was open with some trees, similar to the one proposed in other studies based in some macromammals species found in the locality.Usando las relaciones isotópicas de 13C/12C y 18O/16O presentes en el esmalte y la osteodentina, se infirió la dieta y el ambiente en el cual vivieron cinco especies extintas de herbívoros procedentes del Pleistoceno Tardío de Valsequillo, Puebla, México. Los caballos, los mamutes y el perezoso mostraban una dieta basada exclusivamente en plantas C4, mientras que el carpincho y los gonfoterios exhibían una dieta mixta C3/C4. El tipo de vegetación en el cual estos animales habitaron fue abierto con poca cobertura arbórea, misma que ha sido propuesta en otros estudios usando la presencia de algunas especies de micromamíferos encontradosen la zona

Intranasal administration of mesenchymal stem cell secretome reduces hippocampal oxidative stress, neuroinflammation and cell death, improving the behavioral outcome following perinatal asphyxia
Indexación: Scopus.PerinatalAsphyxia (PA) is a leading cause ofmotor and neuropsychiatric disability associated with sustained oxidative stress, neuroinflammation, and cell death, affecting brain development. Based on a rat model of global PA, we investigated the neuroprotective effect of intranasally administered secretome, derived from human adipose mesenchymal stem cells (MSC-S), preconditioned with either deferoxamine (an hypoxia-mimetic) or TNF-ff+IFN- (pro-inflammatory cytokines). PA was generated by immersing fetus-containing uterine horns in a water bath at 37 ffC for 21 min. Thereafter, 16 ffL of MSC-S (containing 6 ffg of protein derived from 2 ff 105 preconditioned-MSC), or vehicle, were intranasally administered 2 h after birth to asphyxia-exposed and control rats, evaluated at postnatal day (P) 7. Alternatively, pups received a dose of either preconditioned MSC-S or vehicle, both at 2 h and P7, and were evaluated at P14, P30, and P60. The preconditioned MSC-S treatment (i) reversed asphyxia-induced oxidative stress in the hippocampus (oxidized/reduced glutathione); (ii) increased antioxidative Nuclear Erythroid 2-Related Factor 2 (NRF2) translocation; (iii) increased NQO1 antioxidant protein; (iv) reduced neuroinflammation (decreasing nuclearNF-ffB/p65 levels and microglial reactivity); (v) decreased cleaved-caspase-3 cell-death; (vi) improved righting reflex, negative geotaxis, cliff aversion, locomotor activity, anxiety, motor coordination, and recognition memory. Overall, the study demonstrates that intranasal administration of preconditioned MSC-S is a novel therapeutic strategy that prevents the long-term effects of perinatal asphyxia. © 2020 by the authors.https://www.mdpi.com/1422-0067/21/20/780
