Boosting carotenoid content in Malus domestica var. Fuji by expressing AtDXR through an Agrobacterium-mediated transformation method
(Wiley, 2020)Apple (Malus domestica) fruits accumulate negligible levels of carotenoids, antioxidant pigments that are precursors for vitamin A in humans. As vitamin A deficiency is an important public health issue, we aimed at increasing ... -
Multiple late-pleistocene colonisation events of the Antarctic pearlwort Colobanthus quitensis (Caryophyllaceae) reveal the recent arrival of native Antarctic vascular flora
(Wiley, 2020)Aim Antarctica's remote and extreme terrestrial environments are inhabited by only two species of native vascular plants. We assessed genetic connectivity amongst Antarctic and South American populations of one of these ... -
An eight-year survey for canine distemper virus indicates lack of exposure in the endangered Darwin's fox (Lycalopex fulvipes)
(Wildlife Disease Association, 2020)No evidence of exposure to canine distemper virus (CDV) was detected in 70 samples corresponding to 58 wild-trapped Darwin's foxes (Lycalopex fulvipes) in Chile. Given its current endangered status and it being immunologically ... -
Single-nucleotide polymorphisms (snp) mining and their effect on the tridimensional protein structure prediction in a set of immunity-related expressed sequence tags (EST) in Atlantic Salmon (salmo salar)
(Frontiers Media, 2020)Single-nucleotide polymorphisms (SNPs) are single genetic code variations considered one of the most common forms of nucleotide modifications. Such SNPs can be located in genes associated to immune response and, therefore, ... -
Incorporation of nanostructured ReO3 in silica matrix and their activity toward photodegradation of blue methylene
(Springer, 2020)ReO3 were prepared by thermal treatment of the macromolecular Chitosan center dot(ReCl3)(X) and PSP-4-PVP center dot(ReCl3)(X) precursors. The plasmon band in the visible region for the as obtained ReO3 from their visible ... -
Computing the Fukui Function in solid-state chemistry: application to alkaline earth oxides bulk and surfaces
(American Chemical Society, 2020)Fukui functions (FFs) are chemical descriptors that are useful to explain the reactivity of systems toward electron transfer. Whereas they have been widely employed for molecules, their application to extended systems is ... -
Trpml controls actomyosin contractility and couples migration to phagocytosis in fly macrophages
(Rockefeller University Press, 2020)Phagocytes use their actomyosin cytoskeleton to migrate as well as to probe their environment by phagocytosis or macropinocytosis. Although migration and extracellular material uptake have been shown to be coupled in some ... -
Seasonal and spatial variation of trace elements in sediments of three chilean basins
(Sociedad Chilena de Química, 2020)Total concentrations of trace elements can provide fundamental information on the sediment contamination levels of the pollution indexes and the quality guidelines for sediment risk assessment. However, this information ... -
Response to selected ecological parameters by Leptus hringuri Haitlinger, 2000 larvae (Trombidiformes: Erythraeidae) parasitizing treehoppers (Hemiptera: Membracidae) from Bolivia on two host-plant species
(Taylor & Francis, 2020)Larvae of Leptus hringuri parasitizing families (adult female + offspring) of the treehopper Alchisme grossa on two host-plants, Brugmansia suaveolens (BS) and Solanum ursinum (SU), were studied. The effect of microenvironmental ... -
PyProcar: A Python library for electronic structure pre/post-processing
(Elsevier, 2020)The PyProcar Python package plots the band structure and the Fermi surface as a function of site and/or s,p,d,f - projected wavefunctions obtained for each k-point in the Brillouin zone and band in an electronic structure ... -
New ctenochasmatid pterosaur record for Gondwana: discovery in the Lower Cretaceous continental deposits of the Atacama Desert, northern Chile
(Elsevier, 2020)New pterosaur remains from Cerro La Isla, Quebrada Monardes Formation (Lower Cretaceous), Northern Chile, are described. The material comprises mandibular remains preserving dental bases and two vertebrae of the mid cervical ... -
Caracterización de macrófagos de la cavidad peritoneal y su influencia en el Lupus Eritematoso Sistémico (SLE)
(Universidad de Chile, 2019-08)El Lupus Eritematoso Sistémico (LES) es una enfermedad autoinmune caracterizada por la hiperactividad de células T y B autorreactivas, la producción de autoanticuerpos y la formación de complejos inmunes que terminan ... -
Biosíntesis de ácido hialurónico en Saccharomyces cerevisiae
(Universidad de Chile, 2019-08-26)El ácido hialurónico es un polímero que pertenece a los glicosaminglicanos formado por subunidades repetidas de N-acetilglucosamina y ácido glucurónico, forma parte de la matriz extracelular en organismos vertebrados como ... -
Metabolomic profiling of left ventricular diastolic dysfunction in women with or at risk for HIV infection: The women’s interagency HIV study
(Wiley, 2020)Background-—People living with HIV have an increased risk of left ventricular diastolic dysfunction (LVDD) and heart failure. HIVassociated LVDD may reflect both cardiomyocyte and systemic metabolic derangements, but the ... -
Effect of salinity acclimation on osmoregulation, oxidative stress, and metabolic enzymes in the invasive Xenopus laevis
(Wiley, 2020)Aquatic animals often display physiological adjustments to improve their biological performance and hydrosaline balance in saline environments. In addition to energetic costs associated with osmoregulation, oxidative stress, ... -
Stridulation in the wild kissing bug Mepraia spinolai: description of the stridulatory organ and vibratory disturbance signal
(Taylor & Francis, 2020)Stridulation is a type of communication in which a mechanical signal is emitted by the friction of two rigid structures. Stridulation is present in kissing bugs (Reduviidae: Triatominae), where the friction of the proboscis ... -
Phytochemical profile of coryphantha macromeris (engelm.) Britton & Rose (cactaceae) obtained from in vitro culture
