Coronary sinus reentrant tachycardia after atrial fibrillation ablation: From bad to worse  [PDF]
Pietro Turco
World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.42006
Abstract: Herein we present a case of atrial tachycardia as a sequel of AF ablations. A 42-year-old man was admitted to our department because of a very symptomatic tachycardia. The patient, because of paroxysmal AF and typical atrial flutter, had been already submitted (three times) to ablation procedures in both left (pulmonary vein insulation) and right atria (cavo-tricuspidal isthmus). During the electrophysiological study, a huge and very fast atrial tachycardia was induced: 230 ms cycle length, 1/1 atrio-ventricular conduction with the ventricular rate of 260 bpm, complete left bundle branch block, and clinically recognized by the patient. Four minutes later, a 2/1 AV conduction without branch block permitted mapping and ablation. A high-density mapping around isthmus and coronary sinus (CS) was performed. The analysis of the chronological activation clearly showed a circuit propagation around the CS ostium with a very slow conduction in the anterior zone enlightened by the tight color progression, and counterclockwise activation of the right atrium lateral wall. In anterior zone of CS ostium diastolic fragmented electrograms were detected. After preventing his position localization, radiofrequency delivering (35 W) was effective to interrupt the arrhythmia in 3 seconds. Energy delivering was continued to anchor the lesion to the inferior vena cava. Confirmation of successful ablation was determined by unsuccessful attempts at reinduction of the arrhythmia, in basal state and during infusion of isoproterenol.

Turco, Angelo;
Varia Historia , 2006, DOI: 10.1590/S0104-87752006000100008
Abstract: this article treats the great theme of war in africa, which permits multiple articulations. the mandê tradition of west africa permits the understanding of the ways the meaning of organized violence are constituted, especially the just war, with particular attention to the forms of power in relation to territoriality.
Health Impact Assessment: a useful tool for decision makers
Livia Turco
Italian Journal of Public Health , 2007, DOI: 10.2427/5871
Abstract: Health Impact Assessment is defined as ‘the combination of procedures, methods and tools through which it is possible to evaluate a policy, a program or a development plan concerning possible effects on public health and their distribution in the general population’. In a constructive debate this definition points out some interesting observations: - health is not the result of health policies alone, but it is often defined by the attention given to it in other contexts; - health is however the result of policies and it therefore must deserve the attention of Decision Makers; - health must not be taken into consideration without taking into account an evaluation of its distribution and its determinants within a population. Particular attention must therefore be paid into inequalities; - following the Council of the European Union recent conclusions on Health in All Policies we have to consider that everyday environments such as day-care centers, schools,workplaces,neighborhoods and the commute between them have significant effects on health and that health, in turn, has an effect on the economy by enabling active and productive participation in working life. In the past 20 years huge progress has been achieved in the epidemiological contest to define risks. Nowadays, it is known that a low cultural level lowers the capacity to respond to prevention, that elevated pollution levels do represent a health risk, and that the scarce social relationships that elderly people have in our society have strong consequences on their health and their quality of life.
$\mathcal A$-compact mappings
Pablo Turco
Mathematics , 2015,
Abstract: For a fixed Banach operator ideal $\mathcal A$, we study $\mathcal A$-compact polynomials and $\mathcal A$-compact holomorphic mappings. We show that the behavior of $\mathcal A$-compact polynomials is determined by its behavior in any neighborhood of any point. We transfer some known properties of $\mathcal A$-compact operators to $\mathcal A$-compact polynomials. In order to study $\mathcal A$-compact holomorphic functions, we appeal to the $\mathcal A$-compact radius of convergence which allows us to characterize the functions in this class. Under certain hypothesis on the ideal $\mathcal A$, we give examples showing that our characterization is sharp.
The Financial Collapse of Local Bodies: the Case of the Municipality of Taranto
Mario Turco
GSTF Journal on Business Review , 2015, DOI: 10.5176/2010-4804_4.1.357
Abstract: The present work aims to offer a contribute for the evaluation of the opportunity to adopt strategies based on state support or, alternatively, on the managerial autonomy of local bodies in financial trouble. The research, after analyzing the main guidelines at European level and mentioning possible solutions currently laid down in Italian legislation, presents the results of an empirical investigation on the economic effects produced on the local economy by the collapse of the Municipality of Taranto. The choice of the city of Taranto is due both to the significant magnitude of the ascertained debt, which was one of the highest in the history of Italy, and to the considerable economic effects caused by the recovery procedure. Specifically, have been firstly examined the reasons which led to the collapse of the local public authority and the main aspects characterizing the administrative management of the passive mass besides the possible solutions for the definitive implementation of the recovery plan.
Apple as a Source of Dietary Phytonutrients: Bioavailability and Evidence of Protective Effects against Human Cardiovascular Disease  [PDF]
Gianna Ferretti, Imma Turco, Tiziana Bacchetti
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.513134
Abstract:

The dietary consumption of fruit and vegetable is associated with a lower incidence of degenerative diseases such as cardiovascular disease. Most recent interest has focused on the bioactive phenolic compounds in vegetable products. All varieties of apple contain several antioxidants and polyphenols that possess many biological activities, such as antioxidant and anti-inflammation properties. The review describes the nutritional properties of apples and their derivatives, with a particular attention to polyphenol compounds. Moreover, the health benefits of apples and the potential molecular mechanisms against cardiovascular disease are reviewed.

Speed of Adjustment and Infraday/Intraday Volatility in the Italian Stock and Futures Markets  [PDF]
Pietro Gottardo
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.25082
Abstract: We estimate the speed of adjustment of prices to value changes in the Italian stock and futures markets using variances in different return intervals. The paper presents evidence that an assumption of linearity for the relationship volatility-time is untenable when intraday and infraday data are used jointly. Prices adjust to new information within three days, but the process is complex with evidence of overshooting and divergent movements in the smaller return intervals. Firms behave differently according to their inclusion or exclusion from the MIB30 index. The speed of adjustment is strongly related to firm-specific characteristics and the log of capitalization explains some of the cross-sectional variability in the adjustment coefficients for most of the return intervals.
A Theoretical Overview of Bioresponse to Magnetic Fields on the Earth’s Surface  [PDF]
Pietro Volpe
International Journal of Geosciences (IJG) , 2014, DOI: 10.4236/ijg.2014.510097
Abstract: This survey points to the mechanisms of bioresponse caused by magnetic fields (MFs), paying attention to their action not only on ions, molecules and macromolecules, but also on cells, tissues and organisms. The significance of findings concerning the MF-dependence of cell proliferation, necrosis or apoptosis was judged by comparing the results obtained in a solenoid, where an MF can be added to the geomagnetic field (GMF), with those obtained in a magnetically shielded room, where the MFs can be attenuated or null. This comparative criterion was particularly appropriate when the differences detectable between the data provided by experimental samples and the data provided by control samples were rather small, as observed in estimating the MF-influence on total DNA replication, RNA transcription and polypeptide translation. The MF-induced inhibition of apoptosis was considered as a risk potentially leading to accumulation of cancer cells. The analysis also surveyed the MF-dependence of the interactions between host animal cells and infecting bacteria. In relation to studies on the origin and adaptation of life on the Earth, theoretical insights paving the way to elucidating the MF-interactions with biostructures and biosystems of different orders of organization evaluated the possible involvement of the so-called “biological windows”. Analogously to what is known for ionizing radiations, the efficiency of the applied MFs appeared to depend on the complexity of their biological targets.
The Outrageous Discourse of Psychoanalysis for Present-Day Academic Institutions  [PDF]
Pietro Barbetta
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.33021
Abstract: In the following essay I’m going to take a radical position concerning the tendency to eliminate psychoanalysis from the European Academic field and the failure of psychoanalysts and relational therapists to defend psychoanalysis from such aggression. My question is why in Italy—just to make a local example, which I am involved in—different kinds of psychoanalytical traditions are not able to defend themselves from this attack while in France, for another example, all the different branches of relational therapies have been able to unite in making a common effort to take a position for psychoanalysis. One of the main problems, in my opinion, concerns the constitutive marginality of psychoanalysis in relation to Academic Institutions. In my way of writing, I will use psychoanalysis, with “P” in capital character, when referred to Academia, and psychoanalysis, with no capital character, when referred to clinical practice.
The Unexpected Existence of Coding and Non-Coding Fragments along the Eukaryotic Gene  [PDF]
Pietro Volpe
Advances in Biological Chemistry (ABC) , 2015, DOI: 10.4236/abc.2015.52009
Abstract: The pathways leading to synthesis and post-synthetic modification of DNA employed methionine as donor of atoms: the carbon that came from its –CH3 served for DNA replication and repair either in bacteria or humans; its entire –CH3 served instead for building N6-methyladenine and 5-methylcytosine on bacterial DNA and 5-methylcytosine alone on human DNA. In humans, although a slight extra-S asymmetric methylation appeared de novo yielding on parental DNA 5’-m5CpC-3’/ 3’-GpG-5’, 5’-m5CpT-3’/3’-GpA-5’ and 5’-m5CpA-3’/3’-GpT-5’ monomethylated dinucleotide pairs, a heavy symmetric methylation involved in S semiconservatively newly made DNA to guarantee genetic maintenance of –CH3 in 5’-m5CpG-3’/3’-Gpm5C-5’ dimethylated dinucleotide pairs. In this framework, an inverse correlation was found between bulk genomic DNA methylation occurring in S and bulk polyA-containing pre-mRNA transcription taking place in G1 and G2. Thus, probes of 1 × 106 Daltons (constructed using sheared by sonication newly made methylated DNA filaments) revealed a modular organization in genes: after the hypermethylated promoter, they exhibited an alternation of unmethylated coding and methylated uncoding sequences. This encouraged the search for a language that genes regulated by methylation should have in common. An initial deciphering of restriction minimaps with hypomethylatable exons vs. hypermethylatable promoters and introns was improved when the bisulfite technique allowed a direct sequencing of m5C. In lymphocytes, where the transglutaminase gene is inactive, its promoter exhibited two fully methylated CpG-rich domains at 5’ and one fully unmethylated CpG-rich domain at 3’, including the site +1 and a 5’-UTR. At variance, in HUVEC cells, where the transglutaminase gene is active, in the first CpG-rich domain of promoter few doublets lost their –CH3. Such an inverse correlation suggested new hypotheses especially in connection with repair-modification: UV radiation would cause demethylation in given loci of a promoter by chance, whilst even a partial demethylation in this promoter would be able to resume a previously silent pre-mRNA transcription.
