Intra-individual response variability assessed by ex-Gaussian analysis may be a new endophenotype for attention-deficit/hyperactivity disorder
(Facultad de Ciencias, 2015)Intra-individual variability of response times (RTisv) is considered as potential endophenotype for attentional deficit/hyperactivity disorder (ADHD). Traditional methods for estimating RTisv lose information regarding ... -
Intranasal oxytocin increases respiratory rate and reduces obstructive event duration and oxygen desaturation in obstructive sleep apnea patients: a randomized double blinded placebo controlled study
(Elsevier, 2020-10)Background: Activation of the oxytocin network has shown benefits in animal models of Obstructive Sleep Apnea (OSA) as well as other cardiorespiratory diseases. We sought to determine if nocturnal intranasal oxytocin ... -
Intranasal vaccination in mice with an attenuated Salmonella enterica Serovar 908htr A expressing Cp15 of Cryptosporidium: Impact of malnutrition with preservation of cytokine secretion
(Facultad de Ciencias, 2013)Cryptosporidium is a protozoan parasite associated with acute and persistent diarrhea that, even in asymptomatic persons, can impair normal growth and potentially cognitive and physical development in young children. The ... -
Intraosseous lipoma: a case report
(Chile. Universidad Mayor, 2018)OBJECTIVE: The objective of this report was to demonstrate main clinical and histopathologic intraosseous mandibular lipoma features by taking a look at a specific case. CASE DESCRIPTION: A case of intraosseous lipoma in ... -
Intratask Variability As a Correlate for DRD4 and SLC6A3 Variants: A Pilot Study in ADHD
(CIENCIAS, 2015)Behavioral variability may be an ADHD key feature. Currently used ex-Gaussian/Fast Fourier Transform analyses characterize general distribution and oscillatory/rhythmic components of performance but are unable to demonstrate ... -
Introducción: Deseconomizar los mercados, socializar los estudios de la economía
(Chile. Universidad CentralRIL Editores, 2018)Las ciencias sociales que se ocupan del estudio de la economía han tenido un desarrollo impresionante en las últomas décadas. Parte de este desarrollo ha visto eco en Chile, mostrando un importante dinamismo durante los ... -
Invasion dynamics of the European bumblebee Bombus terrestris in the southern part of South America
(NATURE PORTFOLIO, 2021-07-27)Invasive species are one of the main biodiversity loss drivers. Some species can establish and thrive in novel habitats, impacting local communities, as is the case of managed pollinators. In this regard, an invasive ... -
Invasive American Mink: Linking Pathogen Risk Between Domestic and Endangered Carnivores
(CIENCIAS, 2014)Infectious diseases, in particular canine distemper virus (CDV), are an important threat to the viability of wild carnivore populations. CDV is thought to be transmitted by direct contact between individuals; therefore, ... -
Invasive fungal infections in Chile: a multicenter study of fungal prevalence and susceptibility during a 1-year period
(CIENCIAS, 2004)During the first year of an ongoing surveillance program of invasive fungal infections (IFI) a total of 130 patients (56% male) with fungal strains isolated from blood and other sterile sites were reported from 13 hospitals ... -
Inverse Relationship Between Alzheimer's Disease and Cancer: How Immune Checkpoints Might Explain the Mechanisms Underlying Age-Related Diseases
(IOS PRESS, 2020)Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the adult population. There is evidence of an inverse epidemiological relationship between AD and cancer, another prevalent age-related disease. ... -
Investigating how perceived risk and availability of marijuana relate to marijuana use among adolescents in Argentina, Chile, and Uruguay over time
(ELSEVIER IRELAND LTD, 2019)Aims: Amid changing marijuana policies in the Southern Cone, we examined relationships between marijuana related risk factors and marijuana use among adolescents in Argentina, Chile, and Uruguay from 2001 to 2016. Methods: ... -
Involvement of specific laminins and nidogens in the active remodeling of the basal lamina of labial salivary glands from patients with Sjogren's syndrome
(CIENCIAS, 2006)OBJECTIVE: To investigate remodeling of the basal lamina of labial salivary glands (LSGs) from patients with Sjögren's syndrome (SS) by analyzing the expression of specific components that participate in its assembly and ... -
