Can Purified Omega-3 Polyunsaturated Fatty Acids Supplementation Act Blood Pressure Levels in Untreated Normal-High Blood Pressure Subjects with Hypertriglyceridemia?  [PDF]
Maria Leonarda De Rosa
Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.32031
Abstract: Omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) from fish and fish oils appear to protect against coronary heart disease: their dietary intake is in fact inversely associated with cardiovascular disease morbidity/mortality in population studies. Recent evidence suggests that at least a part of this protective effect is mediated by a relatively small but significant decrease in blood pressure (BP) level. In fact, omega-3 PUFAs exhibit wide-ranging biological actions that include regulating both vasomotor tone and renal sodium excretion, partly competing with omega-6 PUFAs for common metabolic enzymes and thereby decreasing the production of vasoconstrictor rather than vasodilator and anti-inflammatory eicosanoids. PUFAs also reduce angiotensin-converting enzyme (ACE) activity, angiotensin II formation. We retrospectively evaluated the long-term effect of a omega-3 PUFAs supplementation on the blood pressure level of 91 hypertriglyceridemic subjects with untreated normal-high blood pressure that were prescribed a 3 grams omega-3 PUFAs supplementation in order to improve their plasma lipid pattern. After 24 months of treatment, systolic blood pressure (SBP) meanly decreased by 2.6 +/- 2.5 mmHg (p = 0.001) and diastolic blood pressure (DBP) by 1.4 +/- 3.1 mmHg (p < 0.001), while basal heart rate decreased by 4.1 +/- 4.6 bpm (p < 0.001). Both SBP and DBP reduction were significantly related to the baseline SBP (p < 0.001) and DBP (p < 0.001), respectively. Diastolic blood pressure change was also inversely related to the patient’s age (p = 0.004). No significant difference was perceived in the metabolic syndrome subgroup. In our retrospective study, highly purified omega-3 PUFAs long-term supplementation is associated with a significant reduction in SBP, DBP, and basal heart rate in hypertriglyceridemic patients with normal-high blood pressure. The main determinants of the omega-3 PUFAs anti-hypertensive effect appear to be the basal blood pressure level and age. Future research will clarify if omega-3 PUFAs supplementation could improve the antihypertensive action of specific blood pressure lowering drug classes and of statins.
Barriers to Entry in Italian Political Parties: Understanding Why Party Leaders Hand over Governments to Technical Experts  [PDF]
Paola Bordandini, Rosa Mulè
Open Journal of Political Science (OJPS) , 2016, DOI: 10.4236/ojps.2016.62020
Abstract: Why are some party governments suspended and replaced by technical governments? There are surprisingly few answers to this important question in the literature. This article contributes to the literature by analyzing the demographic profiles of the parties’ most committed activists, the party delegates. There is very little in the way of comparative, synchronic and diachronic research that seeks to explore similarities and differences in the demographic profile of middle level elites within radically different political and institutional environments. This article aims at filling such void in empirical research. It draws upon an original dataset based on about 4000 interviews to party national delegates of 15 political parties in Italy between 2004 and 2009, and compares the results with those of the first European comparative research of party delegates that dates back to the seventies, the EPPMLE (European Political Parties Middle Level Elites). Our research findings suggest the presence of high entry barriers that prevent young individuals and women fully to participate in the party’s life. This demographic bias may be a key factor in accounting for the advent of technical governments in Italy because it dwarfs the possibility that new human capital helps developing innovative party programmes.
On the Advertising of an Event: A Mathematical Approach  [PDF]
Rosa Ferrentino, Carmine Boniello
Applied Mathematics (AM) , 2017, DOI: 10.4236/am.2017.811119
Abstract:
The present contribution arises with the intent of providing a brief, and therefore not exhaustive, theoretical accommodation of the problematics related to the programming and the achievement of an event. In reality, the aim of the paper is to develop optimal advertising policies for an event that takes place at a given future instant of time (a sport game, a concert, a ballet or a theatre performance) and to minimize the advertising costs concerning the organization of the event. More precisely, the paper faces the problem of how to diffuse over time the informations about a forthcoming event among a population of potential participants and it takes into consideration, among the main vehicles for the dissemination of information, the word-of-mouth effect, a kind of advertising which is independent of the firm advertising policy.
On the Well-Posedness for Optimization Problems: A Theoretical Investigation  [PDF]
Rosa Ferrentino, Carmine Boniello
Applied Mathematics (AM) , 2019, DOI: 10.4236/am.2019.101003
Abstract: In this paper, some theoretical notions of well-posedness and of well-posedness in the generalized sense for scalar optimization problems are presented and some important results are analysed. Similar notions of well-posedness, respectively for a vector optimization problem and for a variational inequality of differential type, are discussed subsequently and, among the various vector well-posedness notions known in the literature, the attention is focused on the concept of pointwise well-posedness. Moreover, after a review of well-posedness properties, the study is further extended to a scalarizing procedure that preserves well-posedness of the notions listed, namely to a result, obtained with a special scalarizing function, which links the notion of pontwise well-posedness to the well-posedness of a suitable scalar variational inequality of differential type.
Peri-implantitis and periodontitis: Use of bacteriological test in dental practice  [PDF]
Francesco Carinci, Rosa Maria Gaudio
Forensic Medicine and Anatomy Research (FMAR) , 2013, DOI: 10.4236/fmar.2013.13010
Abstract: Peri-implantitis has been defined as an inflamematory condition involving dental implants, surrounding mucosa and bone, which lose supporting bone. Although high success rates for endosseous implants have been reported, failures occur, and some implants are lost or removed. At least 10% of the failures have been suggested to be the result of peri-implantitis. One of the major causes of the peri-implantitis is the bacterial colonization of implant surfaces but additional risk factors such as periodontitis, poor oral hygiene, tobacco consumption, prepost operative therapies and genetic susceptibility should be considered. In the present study a real-time PCR bases assay was designed to detect and quantify red complex species, then used to investigate 307 periodontal pocket samples from 127 periodontitis patients and 180 controls. Results demonstrated a significant higher prevalence of red complex species and increased amount of Porphyromonas gingivalis and Treponema denticolain periodontal pocket of periodontitis. Since a higher risk of peri-implantitis occurs in periodontally affected patients, detection and treatment of bacteria is a fundamental objective to ensure dental implant survival.
Application of the New Moroccan Family Code in Spain (with a Gender Perspective)  [PDF]
Gloria Esteban de la Rosa
Beijing Law Review (BLR) , 2013, DOI: 10.4236/blr.2013.44019
Abstract:

The application of the Moroccan Family Code by Spanish legal operators is not simple, to the extent that it is not only a question of knowing its contents, but also, behind each of its articles and, relating to the institutions contained in the Code, there is a specific understanding of the world and, more specifically, family relations. The Spanish system of Private International Law is to serve as a “communication channel” between legislations which are beginning to coincide due to the new private international situations taking place in Spain, as a new foreign population begins to settle, in particular when it comes to female Moroccan immigrants. In these cases, Moroccan family law may be applied or considered by the Spanish authorities, favouring thus the recognition of decisions taken in Morocco.

Cultural Diversity, European Public Policy Exception and Family Law of Muslim Countries  [PDF]
Gloria Esteban de la Rosa
Beijing Law Review (BLR) , 2015, DOI: 10.4236/blr.2015.62015
Abstract: The recognition of cultural diversity as a value of the European Union Law is undoubtedly present in the current process of integration, which, in turn, is related to the maintenance of peace. Without prejudice to the treatment given by national regulations (Private International Law systems) of each Member State to the issue of cultural diversity existing in the current European society, it may be mentioned the positioning that has also been taken by the EU legislature of PIL on the treatment of said diversity. Tools used by the Private International Law system both for European Union Member States and for the European Private International Law system itself to give answers to this multiculturalism located in the territory that comprises the European Union Member States are discussed below. In particular, art. 10 of the Council Regulation (EU) no. 1259/2010, of 20 December 2010, implementing enhanced cooperation in the area of the law applicable to divorce and legal separation. This exception (public policy) will be practically operational in general when it comes to the implementation of the national system of an Islamic countries, because it may be considered that there is a difference between men and women in everything related to family relationships. The aim of this paper is to analyze the possibility of the “recognition method” as a clause for the interpretation of Private International Law to permit the application of foreign Muslim Law by European authorities in family cases and to avoid limping relationships.
Inclusion-Exclusion Policy Latin American Democracies and Distributive Policies  [PDF]
Godofredo Vidal de La Rosa
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.71004
Abstract: This essay explores the influence that political participation has in the development of political equality, and the causal relationship between political equality and democracy. The main interest is in the impact of political participation, especially, voter turnout, and distributive social policies in democratic regimes in Latin-America. Voting process and party competition are focused as the main factors in the regime performance. More specifically, high turnout rates are very influential in the regime path and in the policy process. This thesis is well observed in the “first world”.
Evolution of the Number of Students in Elementary and Secondary School in Portugal and Population Ageing  [PDF]
Cecília Rosa, Edgar Pereira
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57008
Abstract: In this work, we present an application of a mathematical model structured in classes (see [1]) for the study of the influence of population ageing in the evolution of the number of students in elementary school and in secondary school in Portugal, from 1995/96 to 2014/15 (see [2]). Based on historical data, some scenarios of projection are presented, with the aim of quantifying the young student population and its relation with the structure of the population age for the next school years in Portugal (from 2016/2017 to 2020/2021), in the various study cycles. Furthermore, we make a comparative analysis between the projection results presented here and in references [3] and [4]. The dynamic of the model comprises two stages: the first one represents the flow of students that go from one school year to the next, as well as the flow of students that enter or leave the educational system in a certain cycle of studies. The second stage represents the flow of students that go to the next cycle of studies. The simulations were done using Matlab.
The best of 2005 in echocardiography back from EuroEcho 9 – Florence, Italy
Rosa Sicari
Cardiovascular Ultrasound , 2006, DOI: 10.1186/1476-7120-4-11
Abstract: The Meeting of the European Association of Echocardiography (EuroEcho9) that took place in Florence from December 6th to 10th, has just finished achieving the record of abstract submissions and participant attendance (2.842). The interest on ultrasound technologies is very high and is still increasing over time in relation to its widespread employment, often outside the cardiological community. This is a brief report on what went on for those who could not attend the meeting or could not follow all the sessions.During the opening ceremony, the president Alan Fraser announced the result of the recent elections for a new member in the Board. The winner was Prof. Albert Varga from Szeged, Hungary. He has an outstanding curriculum characterized by some key publications on safety of stress echocardiography and evaluating new protocols for the detection of myocardial viability. His election is very welcome inside the Board since he represents an independent and highly appreciated voice of the new European Union countries. For the first time the Association employed a completely electronic voting system (different from the previous one that was conducted via e-mail). The electoral system employed by the Association allows that any echocardiographist from any associated country member (the membership of countries to the European Association does not correspond to the 25 members of the European Union but is much larger), can submit his/her resume to the Board. The candidatures do not go through a selection system unless more than five candidates apply for the same position, as stated in the bylaws of the Association. In that particular case the Board will select the best profiles that would fit for that position. The electronic vote posed some technical problems (many physicians found the access a little bit too complicated) but the time allowed for voting was long enough to overcome these limitations. This is an open and transparent way to have access to the Board independe
