The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms.
2015
Objectives:\ud The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.\ud \ud Methods:\ud Pharmacological manipulation of the activity of CRF receptors, CRF1 and CRF2, was performed in 3T3L1 white pre-adipocytes and T37i brown pre-adipocytes during in vitro differentiation. The expression of genes of the CRF/urocortin system and of markers of white and brown adipocytes was evaluated along with mitochondrial biogenesis and cellular oxygen consumption. Metabolic evaluation of corticosterone-deficient or supplemented Crhr1-null (Crhr1−/−) mice and their wild-type controls was performed alo…
Methylprednisolone-induced hepatotoxicity in a 16-year-old girl with multiple sclerosis.
2018
Multiple sclerosis (MS) is a chronic inflammatory disease with demyelination of the central nervous system. High-dosage corticosteroids are the first-line therapy in the acute relapsing of MS. We report a case of severe high-dose methylprednisolone-induced acute hepatitis in a patient with a new diagnosis of MS. A 16-year-old girl was admitted for urticaria, angioedema, nausea and vomiting a month later she had been diagnosed with MS and treated with high-dosage methylprednisolone. Laboratory investigations showed hepatic insufficiency with grossly elevated liver enzymes. A liver biopsy showed focal centrilobular hepatocyte necrosis with interface hepatitis. Methylprednisolone-induced hepat…
Pharmacogenomics: A Step forward Precision Medicine in Childhood Asthma.
2022
Personalized medicine, an approach to care in which individual characteristics are used for targeting interventions and maximizing health outcomes, is rapidly becoming a reality for many diseases. Childhood asthma is a heterogeneous disease and many children have uncontrolled symptoms. Therefore, an individualized approach is needed for improving asthma outcomes in children. The rapidly evolving fields of genomics and pharmacogenomics may provide a way to achieve asthma control and reduce future risks in children with asthma. In particular, pharmacogenomics can provide tools for identifying novel molecular mechanisms and biomarkers to guide treatment. Emergent high-throughput technologies, …
Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice
2016
Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…
Mucin 1 deficiency mediates corticosteroid insensitivity in asthma
2019
BACKGROUND: The loss of corticosteroid efficacy is an important issue in severe asthma management and may lead to poor asthma control and deterioration of airflow. Recent data indicate that Mucin 1 (MUC1) membrane mucin can mediate corticosteroid efficacy in chronic rhinosinusitis, but the role of MUC1 in uncontrolled severe asthma is unknown. The objective was to analyze the previously unexplored role of MUC1 on corticosteroid efficacy in asthma. METHODS: Mucin 1 expression was evaluated by real-time PCR in human bronchial epithelial cells (HBEC) and blood neutrophils from uncontrolled severe asthma (n=27), controlled mild asthma (n=16), and healthy subjects (n=13). IL-8, MMP9, and GM-CSF …

Dolor y recaída en el alcoholismo: alteraciones en la función moduladora del sistema opioide endógeno sobre el sistema dopaminérgico mesocorticolímbi…
2020
Durant els últims anys, múltiples estudis clínics i epidemiològics han revelat que la presència de dolor crònic està estretament relacionada amb el trastorn per consum d'alcohol (AUD). De fet, el dolor crònic sembla augmentar el risc de patir AUD i predir el consum excessiu d'alcohol i la recaiguda en aquells pacients amb antecedents d'abús d'alcohol. A més, s'ha informat que el dolor té un impacte negatiu en el processament motivacional i de recompensa, ja que altera la funció de sistema mesocorticolímbic (MCLS). Els receptors opioides mu (MOR) són components clau del MCLS i són essencials per al processament de recompenses tant d'estímuls naturals com de drogues d'abús, inclòs l'alcohol. …

Modulations of corticospinal excitability following rapid ankle dorsiflexion in skill- and endurance-trained athletes
2022
Abstract Purpose Long-term sports training, such as skill and endurance training, leads to specific neuroplasticity. However, it remains unclear if muscle stretch-induced proprioceptive feedback influences corticospinal facilitation/inhibition differently between skill- and endurance-trained athletes. This study investigated modulation of corticospinal excitability following rapid ankle dorsiflexion between well-trained skill and endurance athletes. Methods Ten skill- and ten endurance-trained athletes participated in the study. Corticospinal excitability was tested by single- and paired-pulse transcranial magnetic stimulations (TMS) at three different latencies following passive rapid ankl…
Hipoacusia súbita: nueva pauta corticoidea intratimpánica precoz
2019
Desde hace unos años, el tratamiento intratimpánico de enfermedades como la hipoacusia súbita o la Enfermedad de Menière ha ido cobrando importancia. Cada vez han sido más los artículos y las conferencias en congresos que han profundizado en la eficacia del mismo. Hasta el momento, estos tratamientos han sido utilizados como terapias de segunda línea o como terapias de rescate ante el fracaso del tratamiento sistémico. No obstante, la efectividad de este tipo de tratamientos es significativa en comparación con placebo. Mientras que en la sordera súbita clásicamente se ha utilizado el tratamiento intratimpánico en pautas de una dosis semanal, el mismo tratamiento en la enfermedad de Menière …
