Epicardial Fat, Cardiac Geometry and Cardiac Function in Patients with Nonalcoholic Fatty Liver Disease: Association with the Severity of Liver Disea…

2015

Background & Aims Non-alcoholic fatty liver disease (NAFLD) has been associated with increased cardiovascular risk, including coronary artery disease and cardiac dysfunction. In addition, recent evidence highlighted the possible role of epicardial fat as a new cardiometabolic risk factor. We tested the correlation between epicardial fat, alterations in cardiac geometry and function, and severity of liver damage, in patients with biopsy-proven NAFLD. Methods The anthropometric, biochemical and metabolic features were recorded in 147 consecutive biopsy-proven NAFLD cases (Kleiner score). Epicardial fat thickness was measured by echocardiography. Results Epicardial fat was higher in patients w…

L’assedio di Palermo del 1071-1072 nei «Gesta Roberti Wiscardi» di Guglielmo il Pugliese

2021

L’intervento si propone di mettere in evidenza alcune caratteristiche (compositive, ideologico-politiche, retorico-stilistiche) dei «Gesta Roberti Wiscardi» di Guglielmo il Pugliese, l’unico poema epico-storico del sec. XI-XII che tratti della conquista normanna dell’Italia meridionale. I «Gesta Roberti Wiscardi» contano 2833 esametri suddivisi in cinque libri, con un prologo e un epilogo, e si inseriscono in quel vasto ambito di poesia epico-storica (e fondamentalmente celebrativa ed encomiastica) che, dal periodo tardoantico conduce alla ricca produzione di storie e cronache versificate che costituisce una delle più ricorrenti tendenze della letteratura mediolatina durante il sec. XII (e …

South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy

2013

AbstractThe IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore>100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity to examine the deep ice sheet using a variety of novel techniques. We made high-resolution particulate profiles with a laser dust logger in eight of the boreholes during detector commissioning between 2004 and 2010. The South Pole laser logs are among the most clearly resolved measurements of Antarctic dust strata during the last glacial period and can be used to reconstruct paleoclimate records in exceptional detail. Here we use…

New epicardial mapping electrode with warming/cooling function for experimental electrophysiology studies

2010

Cardiac electrical activity is influenced by temperature. In experimental models, the induction of hypothermia and/or hyperthermia has been used for the study of mechanisms of cardiac arrhythmia. A system that allows for localized, controlled induction, besides simultaneously recording electrical activity in the same induced area, needs to be developed ad hoc. This article describes the construction and application of a new system capable of locally modifying the epicardial temperature of isolated hearts and of carrying out cardiac mapping with sufficient spatial resolution. The system is based on a thermoelectric refrigerator and an array of 128 stainless steel unipolar electrodes in encap…

Pacemaker therapy in premature children with high degree AV block.

1998

The smallest pacemaker pulse generator and a steroid-eluting bipolar epicardial lead were implanted in two premature children with symptomatic AV block. Stable capture threshold and high amplitude evoked response electrogram resulted in normal function of the pacemaker Autocapture algorithm, which adjusts output 0.3 V above the measured capture threshold. Autocapture had previously been used only with endocardial leads. Longer-term observation is required.

2D Isochronal Correlation Method to Detect Pacing Capture during Ventricular Fibrillation

2009

During ventricular fibrillation (VF), a portion of myocardial tissue can be captured by pacing at a rate near the fibrillation rate. Interruption of ventricular fibrillation can be favored by achieving stable myocardial capture, lowering the energy required for electrical cardioversion. Existence of myocardial capture during electrical stimulation is determined by visual inspection of electrograms (EGM) by an experienced observer. The objective of this work is the development of a semi-automatic method for the detection of myocardial capture based on the 2D correlation of isochronal maps. In 4 isolated rabbit hearts VF was induced by ventricular pacing with an increasing rate. An array of 1…

Polyphenols, methylxanthines, fatty acids and minerals in cocoa beans and cocoa products

2019

In this study, the nutritional profile and some health benefit of three cocoa bean samples of different origins, including Perù, Ecuador (Criollo) and Ghana (Hybrid) and five samples of cocoa products from Criollo variety at different percentage of cocoa solids (from 70 to 100%), are investigated. The Ecuadorian beans were of the same batch used to obtain the chocolate samples (70% cocoa solids) by processing without conching. All samples were analyzed for their proximate composition, mineral content, fatty acids, total polyphenols, catechin, epicathechin theobromine and caffeine. Fatty acid profiles of the cocoa products were quite similar to those obtained in cocoa beans. The atherogenici…
