Heat Shock Protein-60 and Risk for Cardiovascular Disease

2011

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. There is growing evidence that molecularchaperones, many of which are heat shock proteins HSPs, are involved in CVD pathogenesis. In this review we focus on HSP60,the human mitochondrial chaperone that also displays extramitochondrial and extracellular functions. HSP60 is typically cytoprotectivebut a number of stress conditions determine its conversion to a potentially toxic molecule for cells and tissues. We present illustrative examplesof specific subtypes of CVD where HSP60 is implicated in the initiation and/or progression of disease. The data not only indicatea pathogenic role for HSP60 but also its …

Studies on the genus Atriplex (Chenopodiaceae) in Italy. VIII. Names published by Vincenzo Tineo and Michele Lojacono-Pojero

2023

The typification of the Atriplex names published by Vincenzo Tineo and Michele LojaconoPojero is discussed. Atriplex ambigua, A. dealbata, A. graeci, A. halimoides, A halimoides var. glomerata, A. halimoides var. perglauca, A. polyphylla, and A. ratundifolia are neo- or lectotypified on specimens preserved at FI or PAL and ynonymized with A. glauca (= A. dealbata), A. halimus (= A. halimoides = A. halimoides var. glomerata = A. halimoides var. perglauca), A. rosea (= A. ambigua = A. graeci) and A. tornabenei (= A. polyphylla = A. rotundifolia). The Tineo’s A. arenaria, previously considered as replaced synonym of A. tornabenei, is clarified and typified (neotype) on a specimens deposited at…

The Role of Patient-Specific Morphological Features of the Left Atrial Appendage on the Thromboembolic Risk Under Atrial Fibrillation

2022

BackgroundA large majority of thrombi causing ischemic complications under atrial fibrillation (AF) originate in the left atrial appendage (LAA), an anatomical structure departing from the left atrium, characterized by a large morphological variability between individuals. This work analyses the hemodynamics simulated for different patient-specific models of LAA by means of computational fluid–structure interaction studies, modeling the effect of the changes in contractility and shape resulting from AF.MethodsThree operating conditions were analyzed: sinus rhythm, acute atrial fibrillation, and chronic atrial fibrillation. These were simulated on four patient-specific LAA morphologies, each…

VALUTAZIONE DEI MARKERS INFIAMMATORI E DEGLI INDICI DI DISFUNZIONE ENDOTELIALE IN UNA POPOLAZIONE DI PAZIENTI CON FIBRILLAZIONE ATRIALE PERMANENTE CO…

2022

Negli ultimi anni un numero crescente di studi ha sostenuto il ruolo dell'infiammazione nell'inizio, nel mantenimento e nell'outcome della fibrillazione atriale (FA). Tuttavia, nonostante una grande quantità di informazioni, è ancora oggetto di discussione se la fibrillazione atriale o la cardiopatia strutturale sottostante (SHD) sia la causa del processo infiammatorio. Abbiamo quindi cercato di determinare se il processo infiammatorio riflette una malattia sottostante o l'aritmia "di per sé". Pertanto abbiamo valutato i livelli plasmatici del recettore alfa solubile dell'interleuchina 2 (sIL-2Rα), TNF-α e IL-18 in una coorte di 100 pazienti con FA permanente arruolati consecutivamente (43 …

RENAL SALT WASTING: UNA SINDROME DA INAPPROPRIATA SECREZIONE DI URODILATINA? UNO STUDIO PILOTA

2022

La Renal Salt Wasting Syndrome (RSW) è una sindrome clinica con caratteristiche di laboratorio che si sovrappongono completamente alla sindrome da secrezione inappropriata di ADH (SIADH). La differenza fondamentale tra le due sindromi risiede nel volume extracellulare (ECV), ridotto nella RSW e normale o leggermente aumentato nella SIADH. Le difficoltà nella diagnosi differenziale di questa sindrome e nella comprensione del preciso meccanismo patogenetico hanno contribuito a mettere in discussione l'esistenza stessa di RSW. Considerando le caratteristiche della RSW, è stato studiato il possibile ruolo dei peptidi natriuretici per spiegare la sua patogenesi come ANP e BNP, con risultati inso…

An Automatic System for the Analysis and Classification of Human Atrial Fibrillation Patterns from Intracardiac Electrograms

2008

This paper presents an automatic system for the analysis and classification of atrial fibrillation (AF) patterns from bipolar intracardiac signals. The system is made up of: 1) a feature- extraction module that defines and extracts a set of measures potentially useful for characterizing AF types on the basis of their degree of organization; 2) a feature-selection module (based on the Jeffries-Matusita distance and a branch and bound search algorithm) identifying the best subset of features for discriminating different AF types; and 3) a support vector machine technique-based classification module that automatically discriminates the AF types according to the Wells' criteria. The automatic s…
