Biometric Analysis of Healthy Coronary Arteries in a Chilean Population: An Angiographic Study
(Universidad de la Frontera, 2020-12)Thorough knowledge and understanding of coronary arteries and their anatomy is essential when performing cardiac surgery such as a coronary bypass. Coronary angiography is a minimally invasive method used to evaluate the ... -
Biovera-Epi: A new database on species diversity, community composition and leaf functional traits of vascular epiphytes along gradients of elevation and forest-use intensity in Mexico
(PENSOFT PUBLISHERS, 2021-10-07)Background This data paper describes a new, comprehensive database (BIOVERA-Epi) on species distributions and leaf functional traits of vascular epiphytes, a poorly studied plant group, along gradients of elevation and ... -

(PENSOFT PUBLISHERS, 2021-09-09)Here, we describe BIOVERA-Tree, a database on tree diversity, community composition, forest structure and functional traits collected in 120 forest plots, distributed along an extensive elevational gradient in Veracruz ... -
Boldine inhibits the alveolar bone resorption during ligature-induced periodontitis by modulating the Th17/Treg imbalance
(Chile. Universidad Mayor, 2020-06)Background During periodontitis, tooth-supporting alveolar bone is resorbed when there is an increased expression of the pro-osteolytic factor termed receptor activator of nuclear factor kappa B ligand (RANKL), which is ... -
Boldo, Its Secondary Metabolites and their Derivatives
(BENTHAM SCIENCE PUBL LTD, 2019)Boldo leaves (Boldo folium, from Peumus boldus Mol.) are very frequently used as a medicinal herb in Chile and are exported to many countries to be used in teas or as extracts included in herbal remedies, primarily as an ... -
Bolidophyceae, a Sister Picoplanktonic Group of Diatoms - A Review
(FRONTIERS MEDIA SA, 2018)Pico- and nano-phytoplankton (respectively, 0.2-2 and 2-20 mu m in cell size) play a key role in many marine ecosystems. In this size range, Bolidophyceae is a group of eukaryotes that contains species with cells surrounded ... -
Brazilian Study of Nutrition and Health (EBANS) - Brazilian data of ELANS: methodological opportunities and challenges
(ASSOC MEDICA BRASILEIRA, 2019)BACKGROUND: Epidemiological studies with dietary variables are complex methodologically, being the researcher responsible for anticipating, controlling, reducing and preventing methodological errors. Obesity accounts for ... -
Breaking the optomechanical cooling limit by two drive fields on a membrane-in-the-middle system
(AMER PHYSICAL SOC, 2019)We present a theoretical scheme for ground-state cooling of a mechanical resonator in a membrane-in-themiddle optomechanical system (OMS) driven by two red-detuned drive fields. The details of dynamical evolution of OMS ... -
Bridging Inequality: Cooperative Learning Through Literature in Two Vulnerable Schools in Santiago
(Universidad Nacional de Colombia, 2020-07)This paper reports a qualitative action-research study on the use of cooperative learning through literature in two vulnerable English as a foreign language (EFL) classrooms in Chile. The study aimed at bridging EFL ... -
Building Pyridinium Molecular Wires as Axial Ligands for Tuning the Electrocatalytic Activity of Iron Phthalocyanines for the Oxygen Reduction Reaction
(AMER CHEMICAL SOC, 2018)We have been able to"tune"the electrocatalytic activity of iron phthalocyanine (FePc) and iron hexadodeca-chlorophthalocyanine (16(Cl)FePc) for the oxygen reduction reaction (ORR) by manipulating the"pull effect"of pyridinium ... -
Bursting the unfolded protein response accelerates axonal regeneration
(CIENCIAS, 2016)Peripheral neuropathies refer to a group of conditions in which the peripheral nervous system (PNS) is damaged. These pathological state are are associated with weakness, pain, and loss of motor and sensory control. More ... -
