Novel insights into chromosome evolution of Charadriiformes: extensive genomic reshuffling in the wattled jacana (Jacana jacana, Charadriiformes, Jacanidae)
(2020) [Artículo de periódico]The order Charadriiformes comprises three major clades: Lari and Scolopaci as sister group to Charadrii. Until now, only three Charadriiformes species have been studied by chromosome painting: Larus argentatus (Lari), ... -
Novel insights of effects of pregabalin on neural mechanisms of intracortical disinhibition in physiopathology of fibromyalgia : an explanatory, randomized, double-blind crossover study
(2018) [Artículo de periódico]The fibromyalgia (FM) physiopathology involves an intracortical excitability/inhibition imbalance as measured by transcranial magnetic stimulation measures (TMS). TMS measures provide an index that can help to understand ... -
Novel Machado-Joseph disease-modifying genes and pathways identified by whole-exome sequencing
(2022) [Artículo de periódico]Machado-Joseph disease (MJD/SCA3) is a neurodegenerative polyglutamine disorder exhibiting a wide spectrum of phenotypes. The abnormal size of the (CAG)n at ATXN3 explains ~55% of the age at onset variance, suggesting the ... -
A novel protocol for the isolation of fungal extracellular vesicles reveals the participation of a putative scramblase in polysaccharide export and capsule construction in Cryptococcus gattii
(2019) [Artículo de periódico]Regular protocols for the isolation of fungal extracellular vesicles (EVs) are time-consuming, hard to reproduce, and produce low yields. In an attempt to improve the protocols used for EV isolation, we explored a model ... -

NTPDase, 5′-nucleotidase and adenosine deaminase activities and purine levels in serum of sickle cell anemia patients
(2018) [Artículo de periódico]Sickle cell anemia (SCA) is a hereditary disorder that is characterized by tendency of hemoglobin molecules within the erythrocytes to polymerize under hypoxia conditions, deform the red cells, and promote vaso-occlusion ... -
Nuanced qualitative trait approaches reveal environmental filtering and phylogenetic constraints on lichen communities
(2022) [Artículo de periódico]We propose that a qualitative trait approach based on more detailed nuanced traits may reveal previously overlooked patterns, especially when combined with phylogenetic perspectives. By sampling epiphytic lichens and using ... -
Nuclear factor erythroid-2-related factor 2 signaling in the neuropathophysiology of inherited metabolic disorders
(2021) [Artículo de periódico]Inherited metabolic disorders (IMDs) are rare genetic conditions that affect multiple organs, predominantly the central nervous system. Since treatment for a large number of IMDs is limited, there is an urgent need to find ... -
Nuclear Morphometric Analysis (NMA) : screening of senescence, apoptosis and nuclear irregularities
(2012) [Artículo de periódico]Several cellular mechanisms affect nuclear morphology which can therefore be used to assess certain processes. Here, we present an analytic tool to quantify the number of cells in a population that present characteristics ... -
Nutritional composition of Eragrostis teff and its association with the observed antimutagenic effects
(2019) [Artículo de periódico]Eragrostis teff is an Ethiopian native grass plant ( Poaceae or Gramineae family) whose importance as a crop grain has increased in recent years. The aim of this study is to analyze the nutritional composition of its seeds ... -
