Gingival Crevicular Fluid Zinc- and Aspartyl-Binding Protease Profile of Individuals with Moderate/Severe Atopic Dermatitis
(Chile. Universidad Mayor, 2020)Atopic dermatitis (AD) is a protease-modulated chronic disorder with heterogenous clinical manifestations which may lead to an imprecise diagnosis. To date, there are no diagnostic protease tests for AD. We explored the ... -
Gingival Crevicular Placental Alkaline Phosphatase Is an Early Pregnancy Biomarker for Pre-Eclampsia
(MDPI, 2021-05-13)Early and innovative diagnostic strategies are required to predict the risk of developing pre-eclampsia (PE). The purpose of this study was to evaluate the performance of gingival crevicular fluid (GCF) placental alkaline ... -
Gingival metastasis from a testicular choriocarcinoma: An unusual case report and review of the literature.
(CIENCIAS, 2013)Los tumores metastásicos a la cavidad bucal son lesiones extremadamente raras que representan el 1% de todas las neoplasias malignas bucales y maxilofaciales. La mayoría de los casos reportados afectan más a los huesos ... -
Global ecological predictors of the soil priming effect
(NATURE PUBLISHING GROUP, 2019)Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, ... -
Global homogenization of the structure and function in the soil microbiome of urban greenspaces
(AMER ASSOC ADVANCEMENT SCIENCE, 2021-07)The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six ... -
Global phylogeography and ancient evolution of the widespread human gut virus crAssphage
(NATURE PUBLISHING GROUP, 2019)Microbiomes are vast communities of microorganisms and viruses that populate all natural ecosystems. Viruses have been considered to be the most variable component of microbiomes, as supported by virome surveys and examples ... -
Global phylogeography and genetic diversity of the long-finned pilot whale Globicephala melas, with new data from the southeastern Pacific
(Nature Publishing Group, 2020-02)The matrilineal long-finned pilot whale presents an antitropical distribution and is divided into two subspecies, one in the temperate seas of the Southern Hemisphere and the other restricted to the North Atlantic and ... -
Gluconeogenic Enzymes in beta-Cells: Pharmacological Targets for Improving Insulin Secretion
(ELSEVIER SCIENCE LONDON, 2019)Pancreatic beta-cells express the gluconeogenic enzymes glucose 6-phosphatase (G6Pase), fructose 1,6-bisphosphatase (FBP), and phosphoenolpyruvate (PEP) carboxykinase (PCK), which modulate glucose-stimulated insulin secretion ... -

(Universidad de Talca, 2020-04)Este texto analiza la Ley Nº 21.000 que creó la Comisión para el Mercado Financiero, dando vida a una nueva institucionalidad para la regulación de este, en remplazo de la Superintendencia de Valores y Seguros. El principal ... -
Gradient sperm selection for reproductive techniques in cattle: Is Isolate a suitable replacement for Percoll?
(WILEY, 2018)In assisted reproductive techniques, it is essential to perform a sperm selection to obtain spermatozoa with high motility and membrane integrity for in vitro fertilisation (IVF) and high-DNA integrity for intracytoplasmic ... -
Gramáticas de vida: el censo de 1907 y la población como uso de gobierno
(CIENCIAS, 2013)Este artículo, a partir del censo oficial chileno de 1907 y constatando inexactitudes cuantitativas, pasa revista al ejercicio de la categoría de población y el desmedro en este uso, de la realidad india, poniendo énfasis ... -
Graphene Oxide Quantum Dots as the Support for the Synthesis of Gold Nanoparticles and Their Applications as New Catalysts for the Decomposition of Composite Solid Propellants
(AMER CHEMICAL SOC, 2018)Graphene oxide quantum dot (GOQD) and reduced GOOD (rGOQD) were synthetized using a simple and straight methodology based on an oxidative treatment and sonication. GOQD and rGOQD were used as supporting agents for the in ... -
Green Edge ice camp campaigns: understanding the processes controlling the under-ice Arctic phytoplankton spring bloom
