(ELSEVIER IRELAND LTD, 2019)Background: Use of synthetic cathinones, commonly referred to as"bath salts", has been associated with tens of thousands of emergency department visits in the US; however, few national studies have estimated prevalence of ... -
The Phylogeographic Diversity of EBV and Admixed Ancestry in the Americas-Another Model of Disrupted Human-Pathogen Co-Evolution
(MDPI, 2019)Epstein-Barr virus (EBV) is an etiological agent for gastric cancer with significant worldwide variations. Molecular characterizations of EBV have shown phylogeographical variations among healthy populations and in ... -
Development of 26-year-old mixed forests following different regeneration cutting treatments in Andean temperate rainforests of south-central Chile
(ELSEVIER SCIENCE BV, 2019)Tree regeneration following even-aged silvicultural methods in the evergreen forest type (EFT) has been scarcely studied in Chile, although this is the largest forest type in a region of highly productive native forests. ... -
Effect of diet and type of pregnancy on plasma metabolic response in sheep and its further effect on lamb performance
(SPRINGER, 2019)This trial evaluated the individual and interactional effects of diet and type of pregnancy (twin or single) on plasma metabolic response in ewes and their lambs from late pre-partum to late post-partum. Thus, a flock of ... -
Heart rate variability alterations in infants with spontaneous hypertonia
(NATURE PUBLISHING GROUP, 2019)BACKGROUND: Hypertonia is characterized by increased resting muscle tone. Previous studies have shown that adult patients with hypertonia displayed autonomic imbalance. However, cardiac sympathovagal control in infants ... -
Communicating Branches Between the Median and Ulnar Nerves. Proposal for Inclusion in Terminologia Anatomica
(SOC CHILENA ANATOMIA, 2019)The ulnar and median nerves are widely distributed, innervating the muscles of the forearm and hand. In the latter, it also registers the sensitivity of a significant part of the skin. A series of communicating branches ... -
Arbuscular mycorrhizae and absence of cluster roots in the Brazilian Proteaceae Roupala montana Aubl.
(SPRINGER, 2019)Plants growing on soils poor in phosphorus (P) develop P-acquisition strategies such as symbiotic associations with arbuscular mycorrhizal fungi (AMF). In very poor soils, cluster roots, a non-symbiotic alternative strategy ... -
Antihyperalgesic Activity of Quillaic Acid Obtained from Quillaja saponaria Mol.

Optimal harvest cycle on Nothofagus forests including carbon storage in Southern America: An application to Chilean subsidies in temperate forests
(ELSEVIER SCI LTD, 2019)Different countries may have passed through their forest transitions from net native forest loss to net exotic plantation expansion. More investment in global and national forest monitoring is needed to provide better ... -
Facts and hypotheses about the programming of neuroplastic deficits by prenatal malnutrition
(OXFORD UNIV PRESS INC, 2019)Studies in rats have shown that a decrease in either protein content or total dietary calories results in molecular, structural, and functional changes in the cerebral cortex and hippocampus, among other brain regions, ... -
Integrated genomic epidemiology and phenotypic profiling of Clostridium difficile across intra-hospital and community populations in Colombia
(NATURE PUBLISHING GROUP, 2019)Clostridium difficile, the causal agent of antibiotic-associated diarrhea, has a complex epidemiology poorly studied in Latin America. We performed a robust genomic and phenotypic profiling of 53 C. difficile clinical ... -
Docosahexaenoic acid and hydroxytyrosol co-administration fully prevents liver steatosis and related parameters in mice subjected to high-fat diet: A molecular approach
(WILEY, 2019)Attenuation of high-fat diet (HFD)-induced liver steatosis is accomplished by different nutritional interventions. Considering that the n-3 PUFA docosahexaenoic acid (DHA) modulates lipid metabolism and the antioxidant ... -
