Apical Periodontitis: Histological and Morphometric Characterization of Radicular Cysts and Periapical Granulomas
(SOC CHILENA ANATOMIA, 2018)Apical periodontitis is an inflammatory pathology that affects the periapical tissues of a devitalized tooth. The aim of this study was to histologically and morphometrically characterize lesions of cysts and granulomas ... -
Multiple Aneurysms AnaTomy CHallenge 2018 (MATCH): Phase I: Segmentation
(SPRINGER, 2018)Purpose-Advanced morphology analysis and image-based hemodynamic simulations are increasingly used to assess the rupture risk of intracranial aneurysms (IAs). However, the accuracy of those results strongly depends on the ... -
Mechanical and thermal properties of friction-stir welded joints of high density polyethylene using a non-rotational shoulder tool
(SPRINGER LONDON LTD, 2018)The effects of rotational and welding speed on the mechanical properties and thermal behavior in friction stir welded joints of high-density polyethylene using a non-rotational shoulder have been investigated experimentally. ... -
Transitional habitability: Solutions for post-catastrophe in Chile
(ELSEVIER SCIENCE BV, 2018)Chile faces disasters regularly as the result of earthquakes, floods, mudslides, volcanic eruptions and fires that specially affect vulnerable communities. Despite the accumulated experience, there are still disconnections ... -
Gradient sperm selection for reproductive techniques in cattle: Is Isolate a suitable replacement for Percoll?
(WILEY, 2018)In assisted reproductive techniques, it is essential to perform a sperm selection to obtain spermatozoa with high motility and membrane integrity for in vitro fertilisation (IVF) and high-DNA integrity for intracytoplasmic ... -
Effect of nanosilver surfaces on peptide reactivity towards reactive oxygen species
(ROYAL SOC CHEMISTRY, 2018)The interaction of a terminal tryptophan residue within collagen mimetic peptides when tethered to nanometric silver surfaces was studied using a combination of steady state spectroscopy, ultrafast spectroscopy, and molecular ... -
From whaling to whale watching: Identifying fin whale critical foraging habitats off the Chilean coast
(WILEY, 2018)1. Fin whales ( Balaenoptera physalus) have been documented along the coast of Chile since the early 20th century; however, information on their ecology and movement patterns remains poorly known. 2. In the spring of 2015, ... -
Cryopreservation induces mitochondrial permeability transition in a bovine sperm model
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)When the mitochondria of somatic cells are exposed to pathological calcium overload, these trigger mitochondrial permeability transition (MPT) leading to mitochondrial dysfunction and cell death. Cryopreservation procedures ... -

Revisiting the physiological effects of exercise training on autonomic regulation and chemoreflex control in heart failure: does ejection fraction matter?
(AMER PHYSIOLOGICAL SOC, 2018)Heart failure (HF) is a global public health problem that, independent of its etiology [reduced (HFrEF) or preserved ejection fraction (HFpEF)], is characterized by functional impairments of cardiac function, chemoreflex ... -
RNA-seq analysis of compensatory growth in the skeletal muscle of fine flounder (Paralichthys adspersus)
(ELSEVIER SCIENCE BV, 2018)The fine flounder (Paralichthys adspersus) is a highly quoted flatfish species in the international and Chilean aquaculture markets. Despite presenting extraordinary nutritional value and quality white flesh, P. adspersus ... -
Generation of a protocol for the synthesis of chitosan nanoparticles loaded with florfenicol through the ionic gelation method
(UNIV NACIONAL MAYOR SAN MARCOS, 2018)The formation of nanoparticles of chitosan by the ionic gelation method has a high potential for loading, transport and controlled release of molecules. It is a simple method and the nanoparticles have good absorption, ... -
