Human Infections with Pseudoterranova cattani Nematodes, Chile
(CIENCIAS, 2015)To the Editor: Anisakidosis is an emerging foodborne zoonosis caused by nematode larvae of the Anisakinae subfamily, which includes the genera Anisakis, Pseudoterranova, and Contracecum (1). In natural cycles, anisakid ... -
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 ... -
Huntingtin and Rab27a are involved in the secretion of exosomes from astroglial cells.

Hybrid porous silicon/green synthetized Ag microparticles as potential carries for Ag nanoparticles and drug delivery
(Elsevier BV, 2020-11)In the present work, the fabrication of hybrid porous silicon/green synthetized Ag microparticles was shown and the potential use as carriers for Ag nanoparticles and drug delivery was explored. Hybrid microparticles were ... -
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, ... -
Hydroclimatic variations reveal differences in carbon capture in two sympatric conifers in northern Mexico
(PEERJ INC, 2019)Background. Forest ecosystems are considered among the largest terrestrial carbon sinks. The dynamics of forest carbon depend on where the carbon is stored and its responses to environmental factors, as well as the physiology ... -
Hydrogen effects on the mechanical properties of nanocrystalline free-standing Palladium thin films
(Elsevier Ltd., 2020-05)Pd membranes are used both in hydrogen detection and hydrogen separation devices. Their properties can be improved at the nanometer scale. We simulate atomistically the tensile properties of Pd mono and polycrystalline ... -
Hypertension in Prenatally Undernourished Young-Adult Rats Is Maintained by Tonic Reciprocal Paraventricular-Coerulear Excitatory Interactions
(MDPI, 2021-07-05)Prenatally malnourished rats develop hypertension in adulthood, in part through increased alpha(1)-adrenoceptor-mediated outflow from the paraventricular nucleus (PVN) to the sympathetic system. We studied whether both ... -
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). ... -
Hypoxic Respiratory Chemoreflex Control in Young Trained Swimmers
(FRONTIERS MEDIA SA, 2021-03-29)During an apnea, changes in PaO2 activate peripheral chemoreceptors to increase respiratory drive. Athletes with continuous apnea, such as breath-hold divers, have shown a decrease in hypoxic ventilatory response (HVR), ... -
Ideal Cardiovascular Health and Incident Cardiovascular Disease Among Adults: A Systematic Review and Meta-analysis
(ELSEVIER SCIENCE INC, 2018)Objective: To investigate the association between ideal cardiovascular health (CVH) metrics and incident cardiovascular disease (CVD) by conducting a systematic review and meta-analysis of prospective cohort studies. ... -
Identification and Unusual Properties of the Master Regulator FNR in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)The ability to conserve energy in the presence or absence of oxygen provides a metabolic versatility that confers an advantage in natural ecosystems. The switch between alternative electron transport systems is controlled ... -
Identification of Azadinium poporum (Dinophyceae) in the Southeast Pacific: Morphology, molecular phylogeny, and azaspiracid profile characterization
(Oxford University Press, 2017)Azaspiracids (AZA), a group of lipophilic phycotoxins, are produced by some species of the marine dinophycean genus Azadinium. AZA have recently been detected in shellfish from the Southeast Pacific, however, AZA-producing ... -
Identification of c.1531C>T Pathogenic Variant in the CDH1 Gene as a Novel Germline Mutation of Hereditary Diffuse Gastric Cancer
(Chile. Universidad Mayor, 2019)Germline pathogenic variants in the CDH1 gene are a well-established cause of hereditary diffuse gastric cancer (HDGC) syndrome. The aim of this study was to characterize CDH1 mutations associated with HDGC from Chile, a ... -
Identification of functional signatures in the metabolism of the three cellular domains of life
(PUBLIC LIBRARY SCIENCE, 2019)In order to identify common and specific enzymatic activities associated with the metabolism of the three cellular domains of life, the conservation and variations between the enzyme contents of Bacteria, Archaea, and ...
