Alteraciones metabólicas y del sistema dopaminérgico en un modelo animal de esquizofrenia basado en la inmunización materna durante la gestación
(2018-12-21)[ES] La esquizofrenia es una enfermedad crónica, discapacitante, de inicio precoz, con una prevalencia aproximada del 1%. Una de las hipótesis más respaldadas para la explicación de la etiopatogenia de la enfermedad es la ... -
Alteración de lípidos en la enfermedad de Alzheimer. Estudio en tejido cerebral humano postmortem mediante MALDI-IMS.
(2014-06-19)En el presente estudio, se analizó la distribución lipídica de 3 áreas de hipocampo (CA1, subiculum y giro dentado) en muestras cerebrales de pacientes con enfermedad de Alzheimer y se comparó con muestras de sujetos sin ... -
Alteración de vías moleculares y respuesta clínica en los tumores de cabeza y cuello tratados con terapia biológica con anticuerpos anti-EGFR
(2017-07-20)El cáncer de cabeza y cuello es un término que engloba enfermedades que crecen en los senos paranasales, la cavidad oral, nasal, faringe y laringe. A pe¬sar de que el 90% comparten el origen epidermoide con características ... -
Alteration in molecular markers of oocyte development and intersex condition in mullets impacted by wastewater treatment plant effluents
(Elsevier, 2016-06-11)Wastewater Treatment Plant (WWTP) discharges are an important source of endocrine disrupting chemicals (EDCs) into the aquatic environment. Fish populations inhabiting downstream of WWTP effluents show alterations in gonad ... -
Alteration of the tree–soil microbial system triggers a feedback loop that boosts holm oak decline
(Functional Ecology, 2023)In anthropic savanna ecosystems from the Iberian Peninsula (i.e. dehesa), complex interactions between climate change, pathogen outbreaks and human land use are presumed to be behind the observed increase in holm oak ... -
Alterations and Contaminations in Ceramics Deposited in Underwater Environments: An Experimental Approach
(MDPI, 2021-07-15)Ancient ceramics recovered after a long burial period have probably undergone several alterations and contaminations, introducing a chemical variability, affecting the ceramic’s natural variability. That is, the chemical ... -
Alterations of Oligodendrocyte and Myelin Energy Metabolism in Multiple Sclerosis
(MDPI, 2023-08-18)Multiple sclerosis (MS) is a complex autoimmune disease of the central nervous system (CNS), characterized by demyelination and neurodegeneration. Oligodendrocytes play a vital role in maintaining the integrity of myelin, ... -
Alterations of the Hippocampal Neurogenic Niche in a Mouse Model of Dravet Syndrome
(Frontiers Media, 2020-07-21)Hippocampal neurogenesis, the process by which neural stem cells (NSCs) continuously generate new neurons in the dentate gyrus (DG) of most mammals including humans, is chiefly regulated by neuronal activity. Thus, severe ... -
Altered cross-frequency coupling in resting-state MEG after mild traumatic brain injury
(International Journal of Psychophysiology, 2016)Cross-frequency coupling (CFC) is thought to represent a basic mechanism of functional integration of neural networks across distant brain regions. In this study, we analyzed CFC profiles from resting state Magnetoencephalographic ... -
Altered effective connectivity in sensorimotor cortices is a signature of severity and clinical course in depression
(PNAS, 2021)Functional neuroimaging research on depression has traditionally targeted neural networks associated with the psychological aspects of depression. In this study, instead, we focus on alterations of sensorimotor function ... -
Altered expression of Alzheimer's disease-related genes in the cerebellum of autistic patients: a model for disrupted brain connectome and therapy
(Nature Publishing Group, 2014-05)Autism and Alzheimer's disease (AD) are, respectively, neurodevelopmental and degenerative diseases with an increasing epidemiological burden. The AD-associated amyloid-beta precursor protein-alpha has been shown to be ... -
Altered expression of fibroblast activation protein-α (FAP) in colorectal adenoma-carcinoma sequence and in lymph node and liver metastases
(Impact Journals, 2020-06-15)Colorectal cancer (CRC) is a major health problem in elderly people because of its high incidence and high mortality rate. Despite early screening programs, more than half of CRC patients are diagnosed at advanced stages. ... -
Altered glutamyl-aminopeptidase activity and expression in renal neoplasms
(Biomed Central, 2014-05-30)Background: Advances in the knowledge of renal neoplasms have demonstrated the implication of several proteases in their genesis, growth and dissemination. Glutamyl-aminopeptidase (GAP) (EC. 3.4.11.7) is a zinc metallopeptidase ... -
Altered leaf litter quality exacerbates the negative impact of climate change on decomposition
