Mechanotransduction and epigenetic control in autoimmune diseases
(CIENCIAS, 2011)Differentiation of epithelial cells is required to define tissue architecture and appropriate function of these cells is associated with a specific pattern of gene expression. DNA methylation, post-translational modification ... -
Life without Food and the Implications for Neurodegeneration
(CIENCIAS, 2015)Food availability determines developmental rate, behavior, and survival of animals. Animals that enter diapause or hibernate in response to lack of food have a double advantage: they are able to adapt to environmental and ... -
Interspecific recognition in Chilean parabiotic ant species
(CIENCIAS, 2003)In Chile, Camponotus morosus and Solenopsis gayi sometimes co-inhabit a single nest, seemingly in a parabiotic association. To elucidate the nature of this association we conducted behavioural tests that measured aggression ... -
Insect abundance and damage on the deciduous Nothofagus macrocarpa increase with altitude at a site in the Mediterranean climate zone of Chile
(CIENCIAS, 2015)An understanding of the spatial and temporal patterns of insect abundance and plant damage across altitudinal gradients and the mechanisms driving them is limited. Importantly, little is known in this area in relation to ... -
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 ... -
Influence of lipopolysaccharide outer-core in the intrinsic resistance to antimicrobial peptides and virulence in Edwardsiella ictaluri
(CIENCIAS, 2016)The genus Edwardsiella consists of bacteria with an intrinsic resistance to cyclic cationic antimicrobial peptides (CAMPs). Edwardsiella ictaluri, a pathogen of the catfish (Ictalurus punctatus) and the causative agent of ... -
Iron, copper and immunocompetence
(CIENCIAS, 2007)Microminerals including copper and iron are essential to immunity and health in human beings. The development of powerful tools in analytical cell biology and molecular genetics has facilitated efforts to identify specific ... -
Inflammatory Effects of Edwardsiella ictaluri Lipopolysaccharide Modifications in Catfish Gut
(CIENCIAS, 2014)Bacterial lipopolysaccharides (LPS) are structural components of the outer membranes of Gram-negative bacteria and also are potent inducers of inflammation in mammals. Higher vertebrates are extremely sensitive to LPS but ... -
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 ... -
