Long Non-Coding RNAs Responsive to Salt and Boron Stress in the Hyper-Arid Lluteno Maize from Atacama Desert
(MDPI, 2018)Long non-coding RNAs (lncRNAs) have been defined as transcripts longer than 200 nucleotides, which lack significant protein coding potential and possess critical roles in diverse cellular processes. Long non-coding RNAs ... -
Longitudinal analysis of metalloproteinases, tissue inhibitors of metalloproteinases and clinical parameters in gingival crevicular fluid from periodontitis-affects patients
(CIENCIAS, 2005)BACKGROUND: The aim of this work was to improve the assessment of the periodontal disease status through measurements of extracellular matrix metalloproteinases (MMPs) and their tissular inhibitors (TIMPs) in the gingival ... -
Longitudinal Results of a 10-year Clinical Trial of Repair of Amalgam Restorations
(CIENCIAS, 2015)The aim of this prospective, blind, and randomized clinical trial was to assess the effectiveness of repair of localized clinical defects in amalgam restorations that were initially scheduled for replacement. A cohort of ... -

(International Council for Traditional Music, 2020-11)This article presents a historical overview of traditional music studies in Chile, pointing out some of the main achievements and problems. It describes the origins of traditional music studies through the establishment ... -
Loss of native herbivores triggers diversity decline of ephemeral plant communities
(WILEY, 2023-09)Aim: Evaluate the temporal changes in species diversity, composition, and structure of ephemeral plant communities and the seed bank in response to long-term herbivore exclusion over 11 years in plots with and without ... -
Lung oxidative stress as related to exercise and altitude. Lipid peroxidation evidence in exhaled breath condensate: a possible predictor of acute mountain sickness
(CIENCIAS, 2005)Lung oxidative stress (OS) was explored in resting and in exercising subjects exposed to moderate and high altitude. Exhaled breath condensate (EBC) was collected under field conditions in male high-competition mountain ... -

Lymphocyte b and th17 chemotactic cytokine levels in peri-implant crevicular fluid of patients with healthy, peri-mucositis, and peri-implantitis implants
(APOSTA-REVISTA DE CIENCIAS SOCIALES, 2020)Peri-implantitis is one of the leading causes of implant failure and loss, and its early diagnosis is not currently feasible due to the low sensitivity of currents methods. In the current exploratory cross-sectional study, ... -
M-shaped genioplasty: A new surgical technique for sagittal and vertical chin augmentation: Three case reports
(Facultad de Ciencias, 2012)Several surgical techniques are available for correcting and giving harmony to the lower third of the face. In this respect, some well-known techniques seek to correct the shape and size of the chin using different kinds ... -
Machine learning modeling for the prediction of plastic properties in metallic glasses
(NATURE PORTFOLIO, 2023-01-07)Metallic glasses are one of the most interesting mechanical materials studied in the last years, but as amorphous solids, they differ strongly from their crystalline counterparts. This matter can be addressed with the ... -
Macroecological factors shape local-scale spatial patterns in agriculturalist settlements
(The Royal Society, 2017)Macro-scale patterns of human systems ranging from population distribution to linguistic diversity have attracted recent attention, giving rise to the suggestion that macroecological rules shape the assembly of human ... -

Macroscopic nonclassical-state preparation via postselection
(American Physical Society, 2017)Macroscopic quantum superposition states are fundamental to test the classical-quantum boundary and present suitable candidates for quantum technologies. Although the preparation of such states has already been realized, ... -
Magnon valley Hall effect in CrI3-based van der Waals heterostructures
(American Physical Society, 2020-05)Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ... -
Maintaining close canopy cover prevents the invasion of Pinus radiata: Basic ecology to manage native forest invasibility
(PUBLIC LIBRARY SCIENCE, 2019)Pine invasion is a global threat that is occurring in native forests of diverse regions of the world. This process is arising in a scenario of rapid forest deforestation and degradation. Therefore, elucidate which forests ...
