Paracrine Activation of Hepatic CB1 Receptors by Stellate Cell-Derived Endocannabinoids Mediates Alcoholic Fatty Liver
2008
SummaryAlcohol-induced fatty liver, a major cause of morbidity, has been attributed to enhanced hepatic lipogenesis and decreased fat clearance of unknown mechanism. Here we report that the steatosis induced in mice by a low-fat, liquid ethanol diet is attenuated by concurrent blockade of cannabinoid CB1 receptors. Global or hepatocyte-specific CB1 knockout mice are resistant to ethanol-induced steatosis and increases in lipogenic gene expression and have increased carnitine palmitoyltransferase 1 activity, which, unlike in controls, is not reduced by ethanol treatment. Ethanol feeding increases the hepatic expression of CB1 receptors and upregulates the endocannabinoid 2-arachidonoylglycer…
Medium term effects of different dosage of diuretic, sodium, and fluid administration on neurohormonal and clinical outcome in patients with recently…
2008
Studies have shown that patients with compensated heart failure (HF) receiving high diuretic doses associated with normal sodium diet and fluid intake restrictions demonstrated significant reductions in readmissions and mortality compared with those who received low-sodium diets, and over a 6-month observation period, a reduction in neurohormonal activation was also observed. The aim of this study was to evaluate the effects of different sodium diets associated with different diuretic doses and different levels of fluid intake on hospital readmissions and neurohormonal changes after 6-month follow-up in patients with compensated HF. Four hundred ten consecutive patients with compensated HF …
Normal-sodium diet compared with low-sodium diet in compensated congestive heart failure: is sodium an old enemy or a new friend?
2007
The aim of the present study was to evaluate the effects of a normal-sodium (120 mmol sodium) diet compared with a low-sodium diet (80 mmol sodium) on readmissions for CHF (congestive heart failure) during 180 days of follow-up in compensated patients with CHF. A total of 232 compensated CHF patients (88 female and 144 male; New York Heart Association class II–IV; 55–83 years of age, ejection fraction <35% and serum creatinine <2 mg/dl) were randomized into two groups: group 1 contained 118 patients (45 females and 73 males) receiving a normal-sodium diet plus oral furosemide [250–500 mg, b.i.d. (twice a day)]; and group 2 contained 114 patients (43 females and 71 males) recei…
Prebiotic Xylo-Oligosaccharides Ameliorate High-Fat-Diet-Induced Hepatic Steatosis in Rats
2020
Understanding the importance of the gut microbiota (GM) in non-alcoholic fatty liver disease (NAFLD) has raised the hope for therapeutic microbes. We have shown that high hepatic fat content associated with low abundance of Faecalibacterium prausnitzii in humans and, further, the administration of F. prausnitzii prevented NAFLD in mice. Here, we aimed at targeting F. prausnitzii by prebiotic xylo-oligosaccharides (XOS) to treat NAFLD. First, the effect of XOS on F. prausnitzii growth was assessed in vitro. Then, XOS was supplemented or not with high (HFD, 60% of energy from fat) or low (LFD) fat diet for 12 weeks in Wistar rats (n = 10/group). XOS increased F. prausnitzii growth, having onl…
Effect of massage therapy on neonatal jaundice: systematic review
2019
Objetivo: Identificar, evaluar y sintetizar la mayor evidencia disponible sobre el efecto del masaje en la ictericia en neonatos a término tratados o no con fototerapia. Método: Se desarrolló una revisión siguiendo la declaración PRISMA. Para ello se realizóuna exhaustiva búsqueda sistemática en las bases de datos PubMed, Cuiden, Scopus, Scielo y Cnki de los artículos publicados entre enero del 2009 y junio del 2018. Los estudios seleccionados fueron sometidos a una evaluación de la calidad metodológica mediante la escala PEDro.

A New Environmentally-Friendly Colorimetric Probe for Formaldehyde Gas Detection under Real Conditions
2018
[EN] A new environmentally-friendly, simple, selective and sensitive probe for detecting formaldehyde, based on naturally-occurring compounds, through either colorimetric or fluorescence changes, is described. The probe is able to detect formaldehyde in both solution and the gas phase with limits of detection of 0.24 mM and 0.7 ppm, respectively. The probe has been tested to study formaldehyde emission in contaminated real atmospheres. The supported probe is easy to use and to dispose, and is safe and suitable as an individual chemodosimeter.
Electrical measurements in µ-EDM
2008
The phenomena occurring between the electrodes in electric discharge machining when manufacturing features on the micro-metre scale (µ-EDM) is not fully understood. Poor quantitative knowledge of the sources of variability affecting this process hinders the identification of its natural tolerance limits. Moreover, improvements in measuring systems contribute to the acquisition of new information that often conflicts with existent theoretical models of this process. The prime objective of this paper is to advance the experimental knowledge of µ-EDM by providing a measurement framework for the electrical discharges. The effects of the electrodes metallic materials (Ag, Ni, Ti, W) on the elect…
Mitchell in Italia
2017
L'articolo, postfazione al libro Pictorial Turn. Saggi di cultura visuale, mette in evidenza e collega gli studi italiani che hanno subito l'influenza delle teorizzazioni di WJT Mitchell e che hanno contribuito a creare la corrente italiana della visual culture attraverso discipline differenti come le letterature comparate, l'estetica, la filosofia, gli studi sul cinema, persino l'architettura.
Exentos de la fiscalidad del General en el Reino de Valencia. La reivindicación de inmunidad por el clero regular.
2020
Les relacions entre la Generalitat valenciana i el clergat regular experimentaren fortes tensions al segle XVII amb motiu de l’exempció fiscal dels eclesiàstics, especialment els mendicants. L’anàlisi d’aquests conflictes ens permet apropar-nos a la realitat efectiva d’un privilegi fiscal poc conegut en la seua incidència i derivacions.
Multitasking associative networks.
2012
We introduce a bipartite, diluted and frustrated, network as a sparse restricted Boltzman machine and we show its thermodynamical equivalence to an associative working memory able to retrieve multiple patterns in parallel without falling into spurious states typical of classical neural networks. We focus on systems processing in parallel a finite (up to logarithmic growth in the volume) amount of patterns, mirroring the low-level storage of standard Amit-Gutfreund-Sompolinsky theory. Results obtained trough statistical mechanics, signal-to-noise technique and Monte Carlo simulations are overall in perfect agreement and carry interesting biological insights. Indeed, these associative network…
