(2020-08-01)Objectives: This study aimed to compare the clinical features, damage accrual, and survival of patients with familial and sporadic systemic lupus erythematosus (SLE). Methods: A multi-ethnic, multinational Latin American ... -
Data-Driven Iterative Learning Predictive Control for Power Converters
(2022-12-01)This letter proposes a data-driven iterative learning predictive control architecture for power converters. The main objectives of this letter are to enhance the robustness and remain the high performance of finite control-set ... -
Modulation of intracellular ph in human ovarian cancer
(2016-01-01)To sustain tumor growth, the cancer cells need to adapt to low levels of oxygen (i.e., hypoxia) in the tumor tissue and to the tumor-associated acidic microenvironment. In this phenomenon, the activation of the sodium/proton ... -
Role for tetrahydrobiopterin in the fetoplacental endothelial dysfunction in maternal supraphysiological hypercholesterolemia
(2016)Maternal physiological hypercholesterolemia occurs during pregnancy, ensuring normal fetal development. In some cases, the maternal plasma cholesterol level increases to above this physiological range, leading to maternal ... -
Predictors of damage accrual in systemic lupus erythematosus : a longitudinal observational study with focus on neuropsychological factors and anti-neuronal antibodies
(2019-11-01)Objective: Central nervous system disease occurs in over 20% of patients with systemic lupus erythematosus (SLE) resulting in major morbidity and damage. Cognitive dysfunction is common in SLE, but the cause remains uncertain ... -
Probability of major depression classification based on the SCID, CIDI, and MINI diagnostic interviews : A synthesis of three individual participant data meta-analyses
(2020-12)Introduction: Three previous individual participant data meta-analyses (IPDMAs) reported that, compared to the Structured Clinical Interview for the DSM (SCID), alternative reference standards, primarily the Composite ... -

(2020-07-01)Reading levels in primary education students are still deficient in Chile, despite the development of reading promoting iniciatives. Moreover, teaching practices of reading are present a low cognitive challenge. Therefore, ... -
Endocytic motif on a biotin-tagged hiv-1 env modulates the co-transfer of env and gag during cell-to-cell transmission
(2021-09)During HIV-1 transmission through T cell virological synapses, the recruitment of the envelope (Env) glycoprotein to the site of cell–cell contact is important for adhesion and for packaging onto nascent virus particles ... -
Dopaminergic inhibition of human neutrophils is exerted through D1-like receptors and affected by bacterial infection
(2022-12)Dopamine (DA) affects immune functions in healthy subjects (HS) and during disease by acting on D1-like (D1 and D5) and D2-like (D2, D3 and D4) dopaminergic receptors (DR); however, its effects on human polymorphonuclear ... -
