(UNIV AUSTRAL CHILE, FAC CIENCIAS FORESTALES, 2019)Drimys winteri is an abundant tree species in the natural forests of Chile, growing as secondary forest of high ecological and economical importance between 41 degrees and 43 degrees S. The height-diameter relationship is ... -
Mitochondria in Developmental and Adult Neurogenesis
(SPRINGER, 2019)Generation of new neurons is a tightly regulated process that involves several intrinsic and extrinsic factors. Among them, a metabolic switch from glycolysis to oxidative phosphorylation, together with mitochondrial ... -
Do physical activity, commuting mode, cardiorespiratory fitness and sedentary behaviours modify the genetic predisposition to higher BMI? Findings from a UK Biobank study
(NATURE PUBLISHING GROUP, 2019)Objective To investigate whether the association between a genetic profile risk score for obesity (GPRS-obesity) (based on 93 SNPs) and body mass index (BMI) was modified by physical activity (PA), cardiorespiratory fitness, ... -
Synaptotagmin-1 overexpression under inflammatory conditions affects secretion in salivary glands from Sjogren's syndrome patients
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2019)Sjogren's syndrome (SS) is an autoimmune exocrinopathy associated with severe secretory alterations by disruption of the glandular architecture integrity, which is fundamental for a correct function and localization of the ... -
Multidecadal environmental pollution in a mega-industrial area in central Chile registered by tree rings
(ELSEVIER, 2019)One of the most polluted areas in Chile is the Ventanas Industrial Area (VIA; 32.74 degrees S / 71.48 degrees W), which started in 1958 and today comprises around 16 industries in an area of ca. 4 km(2). A lack of consistent ... -
New Negations on the Membership Functions of Type-2 Fuzzy Sets
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)Type-2 fuzzy sets (T2FSs) were introduced by L. A. Zadeh in 1975 as an extension of type-1 fuzzy sets (T1FSs). In this extension, the degree to which an element belongs to a set is just a label of the linguistic ... -
Three-dimensional skeletal changes after early proportional condylectomy for condylar hyperplasia
(CHURCHILL LIVINGSTONE, 2019)The purpose of this study was to evaluate volumetric and dentoskeletal changes in 21 patients with active unilateral condylar hyperplasia (AUCH) after proportional condylectomy. A split-mouth design was used: control group ... -
Polyphasic characterization of Epicoccum sorghinum: A tenuazonic acid producer isolated from sorghum grain
(ELSEVIER SCIENCE BV, 2019)Epicoccum sorghinum isolates from sorghum grain grown in Brazil were characterized using a polyphasic approach based on morphological, genetic and physiologic features. A considerable intraspecific variability was observed. ... -
Schwann cells are early and active participants of axonal degeneration
(WILEY, 2019)Axonal degeneration in adult organisms is a common end point of several diseases leading to loss of neuronal function and circuit remodeling. It has been long assumed that axonal degeneration takes place by means of neuronal ... -
The association of grip strength with health outcomes does not differ if grip strength is used in absolute or relative terms: a prospective cohort study
(OXFORD UNIV PRESS, 2019)Background: higher grip strength is associated with better health outcomes. The optimal way to report grip strength (i.e. absolute vs. relative) for prediction, however, remains to be established. Methods: in participants ... -
Mechanical performance of lightweight polycrystalline Ni nanotubes
(ELSEVIER SCIENCE BV, 2019)The mechanical properties of metallic nanowires and nanotubes were investigated using atomistic molecular dynamics simulations on Ni polycrystalline structures, similar to those experimentally obtained by Atomic Layer ... -
Comparative genomics identifies potential virulence factors in Clostridium tertium and C. paraputrificum
(TAYLOR & FRANCIS INC, 2019)Some well-known Clostridiales species such as Clostridium difficile and C. perfringens are agents of high impact diseases worldwide. Nevertheless, other foreseen Clostridiales species have recently emerged such as Clostridium ... -
Activating PTEN Tumor Suppressor Expression with the CRISPR/dCas9 System
(CELL PRESS, 2019)PTEN expression is lost in many cancers, and even small changes in PTEN activity affect susceptibility and prognosis in a range of highly aggressive malignancies, such as melanoma and triple-negative breast cancer (TNBC). ... -
Diapause induces functional axonal regeneration after necrotic insult in C. elegans
(PUBLIC LIBRARY SCIENCE, 2019)Many neurons are unable to regenerate after damage. The ability to regenerate after an insult depends on life stage, neuronal subtype, intrinsic and extrinsic factors. C. elegans is a powerful model to test the genetic and ... -
Country's International Reputation Index
(PALGRAVE MACMILLAN LTD, 2019)Nowadays it is very common to make decisions about our actions and behaviors based on a series of perceptions, which have been created according to a series of variables, and in many cases their deep knowledge is unnecessary. ... -
Pulsed radiofrequency of superior cervical ganglion for treatment of painful post-traumatic trigeminal neuropathy (PTTN): A case series report
