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 ... -
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 ... -
Injury to the nervous system: A look into the ER
(CIENCIAS, 2016)Injury to the central or peripheral nervous systems leads to the loss of cognitive and/or sensorimotor capabilities that still lack an effective treatment. Although injury to the nervous system involves multiple and complex ... -
Hypoxia-related lipid peroxidation: Evidences, implications and approaches
(CIENCIAS, 2007)Hypoxia may be intensified by concurrent oxidative stress. Lack of oxygen in relation to aerobic ATP requirements, as hypoxia has been defined, goes along with an increased generation of reactive oxygen species (ROS). ... -
Hydration status after exercise affect resting metabolic rate and heart rate variability
(CIENCIAS, 2015)Introducción: La variabilidad del ritmo cardiaco y la tasa metabólica basal se utilizan en evaluaciones de deportistas. La deshidratación por ejercicio puede conducir a pérdidas de hasta 5% de la masa corporal. En consecuencia, ... -
In Vitro Activities of Eight Antifungal Drugs against a Global Collection of Genotyped Exserohilum Isolates
(CIENCIAS, 2015)The in vitro susceptibilities of 24 worldwide Exserohilum isolates belonging to 10 species from human and environmental sources were determined for eight antifungal drugs. The strains were characterized by internal transcribed ... -
Humic acids as molecular assemblers in the surface-enhanced Raman scattering detection of polycyclic aromatic hydrocarbons
(CIENCIAS, 2008)A humic acid (HA) extracted from lignite was successfully used in surface-enhanced Raman scattering SERS experiments as molecular occlusion assembler deposited onto a Ag colloidal surface to detect the polycyclic aromatic ... -
Histopathological findings in Gonads of Xenopus laevis from Central Chile.
(CIENCIAS, 2014)A fin de realizar un estudio histológico gonadal, se capturaron ejemplares adultos de Xenopus laevis en cuatro sitios de la región central de Chile. Los resultados evidenciaron ausencia de alteraciones gonadales en hembras, ... -
Increased acinar damage of salivary glands of patients with Sjogren's syndrome is paralleled by simultaneous imbalance of matrix metalloproteinase 3/tissue inhibitor of metalloproteinases 1 and matrix metalloproteinase 9/tissue inhibitor of metalloproteinases 1 ratios
(CIENCIAS, 2005)OBJECTIVE: Previous findings in labial salivary glands (LSGs) from patients with Sjögren's syndrome (SS) suggest that increased activity and expression of matrix metalloproteinase 9 (MMP-9) and MMP-3 trigger the destruction ... -
Infection and exposure to vector-borne pathogens in rural dogs and their ticks, Uganda
(CIENCIAS, 2015)Background: In rural parts of Africa, dogs live in close association with humans and livestock, roam freely, and usually do not receive prophylactic measures. Thus, they are a source of infectious disease for humans and ... -
Heart rate recovery normality data recorded in response to a maximal exercise test in physically active men
(CIENCIAS, 2014)Background: Despite a growing clinical interest in determining the heart rate recovery (HRR) response to exercise, the limits of a normal HRR have not yet been well established. Purpose: This study was designed to examine ... -
