Natural-mente: no existen dos narices iguales
(2017-05-01)La forma en què sentim una carícia, un so, un color, un sabor o una olor és igual per a tots? Els sistemes sensorials de distintes espècies són diferents, varien respecte al tipus d'energia (per exemple, hi ha animals ... -
Neonatal tumor necrosis factor alpha promotes diabetes in nonobese diabetic mice by CD154-independent antigen presentation to CD8(+) T cells
(Rockefeller University Press, 2000)Neonatal islet-specific expression of tumor necrosis factor (TNF)-α in nonobese diabetic mice promotes diabetes by provoking islet-infiltrating antigen-presenting cells to present islet peptides to autoreactive T cells. ... -
Neural architecture of the vertebrate brain: implications for the interaction between emotion and cognition
(Elsevier, 2019)Cognition is considered a hallmark of the primate brain that requires a high degree of signal integration, such as achieved in the prefrontal cortex. Moreover, it is often assumed that cognitive capabilities imply “superior” ... -
Neuregulin 1-ErbB module in C-bouton synapses on somatic motor neurons: molecular compartmentation and response to peripheral nerve injury
(Nature, 2017)The electric activity of lower motor neurons (MNs) appears to play a role in determining cell-vulnerability in MN diseases. MN excitability is modulated by cholinergic inputs through C-type synaptic boutons, which display ... -
Neuregulin-1 is associated to postsynaptic sites contacting afferent C-type cholinergic terminals on lower motoneurons: changes in murine models of motoneuron diseases
(2014)Pioneering ultrastructural studies have defined different types of synapses (F-, S- and C-type boutons) on lower motoneurons (MNs). C-Type boutons are large nerve terminals characteristic of somatic alpha-MNs and display ... -
Neuroinflammatory Signals in Alzheimer Disease and APP/PS1 Transgenic Mice Correlations With Plaques, Tangles, and Oligomeric Species
(Oxford Journals, 2015)To understand neuroinflammation-related gene regulation during normal aging and in sporadic Alzheimer disease (sAD), we performed functional genomics analysis and analyzed messenger RNA (mRNA) expression by quantitative ... -
Neuroprotection by neurotrophic factors and membrane depolarization is regulated by calmodulin kinase IV
(American Society for Biochemistry and Molecular Biology, 2008)Neurotrophic factors promote motoneuron (MN) survival through increased intracellular calcium (Ca(2+)) and regulation of the phosphatidylinositol (PI) 3-kinase/protein kinase B (PKB) pathway by calmodulin (CaM). Activation ... -
Neuropsychiatric Symptoms and Quality of Life in Spanish Alzheimer's Disease Patients During COVID-19 Lockdown
(Wiley, 2020)Background and purpose: The COVID epidemic is affecting individuals worldwide, and Alzheimer's disease (AD) and amnesic mild cognitive impairment (MCI) patients are at risk due to their characteristics and age. We analysed ... -
NF-κB signaling pathways: role in nervous system physiology and pathology
(Sage, 2013-04)Intracellular pathways related to cell survival regulate neuronal physiology during development and neurodegenerative disorders. One of the pathways that have recently emerged with an important role in these processes is ... -
Nivel de conocimiento de la enfermedad de Alzheimer en cuidadores y población general
(Elsevier, 2019-05-11)Introducción El conocimiento de la enfermedad de Alzheimer es fundamental para el diagnóstico precoz y para reducir la sobrecarga del cuidador. El objetivo fue evaluar el grado de conocimiento de la enfermedad de Alzheimer ... -
Non-enzymatic modification of aminophospholipids by carbonyl-amine reactions
(MDPI, 2013)Non-enzymatic modification of aminophospholipids by lipid peroxidation-derived aldehydes and reducing sugars through carbonyl-amine reactions are thought to contribute to the age-related deterioration of cellular membranes ... -
Nusinersen ameliorates motor function and prevents motoneuron Cajal body disassembly and abnormal poly(A) RNA distribution in a SMA mouse model
(Nature Publishing Group, 2020)Spinal muscular atrophy (SMA) is a devastating autosomal recessive neuromuscular disease characterized by degeneration of spinal cord alpha motor neurons (αMNs). SMA is caused by the homozygous deletion or mutation of the ... -
Obesity changes the human gut mycobiome
(Nature Publishing Group, 2015)The human intestine is home to a diverse range of bacterial and fungal species, forming an ecological community that contributes to normal physiology and disease susceptibility. Here, the fungal microbiota (mycobiome) in ... -
Obesity-associated deficits in inhibitory control are phenocopied to mice through gut microbiota changes in one-carbon and aromatic amino acids metabolic pathways
(BMJ Publishing GroupBritish Society of Gastroenterology, 2021-01)Background Inhibitory control (IC) is critical to keep long-term goals in everyday life. Bidirectional relationships between IC deficits and obesity are behind unhealthy eating and physical exercise habits. Methods We ... -
Olfactory and amygdalar structures of the chicken ventral pallium based on the combinatorial expression patterns of LIM and other developmental regulatory genes
(Wiley, 2009)We compared the combinatorial expression patterns of several LIM domain-containing regulatory genes in the ventrolateral pallium of mouse and chicken, in order to identify the homologues of the ventral pallial amygdala ... -
Oxidative damage compromises energy metabolism in the axonal degeneration mouse model of X-Adrenoleukodystrophy
(Mary Ann Liebert, Inc., 2011)Aims: Chronic metabolic impairment and oxidative stress are associated with the pathogenesis of axonal dysfunction in a growing number of neurodegenerative conditions. To investigate the intertwining of both noxious factors, ... -
Oxidative stress underlying axonal degeneration in adrenoleukodystrophy: a paradigm for multifactorial neurodegenerative diseases?
(Elsevier, 2012)X-linked adrenoleukodystrophy (X-ALD) is an inherited neurodegenerative disorder expressed as four disease variants characterized by adrenal insufficiency and graded damage in the nervous system. X-ALD is caused by a loss ... -
Palbociclib has antitumour effects on Pten-deficient endometrial neoplasias
(Wiley, 2017-04-28)PTEN is one of the most frequently mutated genes in human cancers. The frequency of PTEN alterations is particularly high in endometrial carcinomas. Loss of PTEN leads to dysregulation of cell division, and promotes the ... -
Papel del frijol negro Phaseolus vulgaris en el estado nutricional de la población guatemalteca
