(Universidad de Chile, 2020)Las plantas de la familia Rosaceae producen sorbitol durante la fotosíntesis. Este es un alcohol de azúcar sintetizado por la aldosa 6-fosfato reductasa (A6PR) a partir de glucosa 6-fosfato en conjunto con la oxidación ...
-
(MDPI, 2022)Studies from complex networks have increased in recent years, and different applications have been utilized in geophysics. Seismicity represents a complex and dynamic system that has open questions related to earthquake ...
-
(Elsevier, 2021)Chemical investigation of the alkaloid extract of the aerial parts of Schizanthus tricolor led to the targeted isolation of 26 hygroline derivatives of which 20 were fully characterized. They have not yet been described ...
-
(Wiley, 2022)In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early phase ...
-
(MDPI, 2022)We undertook multi-proxy analyses on two sediment cores from Lago Pato, a small lake basin at 51 degrees S topographically separated from Lago del Toro in Torres del Paine (TdP), to provide insights into glacier dynamics ...
-
(Universidad de Chile., 2018)La Septicemia Rickettsial Salmonídea (SRS) es una enfermedad que afecta a las especies salmónidas, causada por la bacteria Piscirickettsia salmonis, y que causa pérdidas de millones de dólares en la industria salmonera ...
-
(Universidad de Chile, 2022)El lupus eritematoso sistémico (LES) es una enfermedad autoinmune caracterizada por la producción de numerosos anticuerpos contra componentes del núcleo celular, como ADN doble hebra (ADNdh), provocando la afección de ...

Clonamiento de los genes flgC y flgD de Piscirickettsia salmonis y estudio de su expresión in vivo (Universidad de Chile., 2004)El patógeno Piscirickettsia salmonis es el agente causal del síndrome rickettsial del salmón (SRS), enfermedad que afecta en gran medida a la industria salmonera nacional. Esta bacteria gram negativa ha sido descrita ...
-
(Amer Geophysical Union, 2021)Using a time series of geomagnetic storm events between 1957 and 2019, obtained by selecting storms where Dst<-50 nT, we have analyzed the probability of occurrence of moderate, intense, and severe events. Considering that ...
-
(MDPI, 2022)Mepraia parapatrica is one of the lesser known and less abundant sylvatic triatomine species naturally infected by the protozoan Trypanosoma cruzi, the etiological agent of Chagas disease. M. parapatrica lives in sympatry ...
-
(Royal Soc., 2022)Molecular-based analysis has become a fundamental tool to understand the role of Quaternary glacial episodes. In the Magellan Province in southern South America, ice covering during the last glacial maximum (20 ka) radically ...
-
(Oxford, 2022)Long-lived magnetic fields are known to exist in upper main-sequence stars, white dwarfs, and neutron stars. In order to explore possible equilibrium configurations of the magnetic field inside these stars, we have performed ...
-
(Universidad de Chile., 2005)Grapevine fanleaf es una de las más importantes y diseminadas enfermedades de la vid causadas por el GFLV (virus de hoja en abanico de la vid). El genoma de GFLV está compuesto de dos fragmentos de ARN de hebra simple ...
-
(MDPI, 2022)The desire to harness solar energy to address current global environmental problems led us to investigate two-dimensional (2D) core-shell hybrid photocatalysts in the form of a 2D-TiO2-surfactant, mainly composed of fatty ...
-
(Inst Paleobiologii Pan, 2021)We describe partial remains of a non-pterodactyloid pterosaur from Upper Jurassic levels of the Atacama Desert in northern Chile. The material includes a left humerus, a possible dorsal vertebra, and the shaft of a wing ...
-
(Inst Paleobiologii Pan, 2021)This study presents two specimens of Chimaeriformes from Upper Jurassic strata of central Chile. The material was recovered from Tithonian levels of the Baños del Flaco Formation and includes two different individuals, ...
-
(Elsevier, 2021)Layered hybrid ZnO (2D) intercalated by myristic acid (MA) with (0D) CdTe quantum dots (QDs) was designed to increase the conversion efficiency of photochemical energy. The results showed that the introduction of CdTe QDs ...
-
(American Physical Society, 2022)We revisit the observable used for the direct measurements of the electron's g factor. This is done by considering the subleading effects of the large magnetic background field and virtual Standard Model processes. We find ...
-
(MDPI, 2021)Mediterranean central Chile is globally recognized as a hotspot for terrestrial biodiversity due to its high endemism and massive habitat loss. However, within the rural landscape of central Chile, significant extents ...
