Dark chocolate could prevent pre-clinical atherosclerosis
No full textWe have read with great interest the paper “Effects of Dark Chocolate and Almonds on Cardiovascular Risk Factors in Overweight and Obese Individuals: A Randomized Controlled-Feeding Trial” by Lee and coworkers [1] and we found their results of importance in the field of clinical prevention. Authors demonstrate that consumption of almonds alone or combined with dark chocolate under controlled feeding conditions improves lipid profiles. Incorporating almonds, dark chocolate, and cocoa into a typical American diet without exceeding energy needs may reduce the risk of coronary heart diseas
The Influence of Health on Gross Domestic Product and National Income
Full text linkIt is beyond question how the Gross Domestic Product (GDP) and the other National Income and Product Accounts (NIPA) have been groundbreaking in the economic studies and researches of the last century, nevertheless they are often targets of criticism as a result of their failure in including non-market activities in their estimates. Since the beginning of the last century the technophysio evolution has enabled a fivefold increase of the average retirement period, an increase of seven times of the portion of individuals who lives to retire and a fourfold increase of the leisure time of those who are still in the labor force
Periodically driven interacting electrons in one dimension: Many-body Floquet approach
No full textWe propose a method to study the time evolution of correlated electrons driven by a harmonic perturbation. Combining Floquet formalism to include the time-dependent field and cluster perturbation theory to solve the many-body problem in the presence of short-range correlations, we treat the electron double dressing, by photons and by e-e interactions, on the same footing. We apply the method to an extended Hubbard chain at half occupation, and we show that in the regime of small field frequency and for given values of field strength, the zero-mode Floquet band is no longer gapped and the system recovers a metallic state. Our results are indicative of an omnipresent mechanism for insulator-to-metal transitions in one-dimensional systems

Lifestyle at Time of COVID-19: How Could Quarantine Affect Cardiovascular Risk
Full text linkCOVID-19 is causing a global pandemic with a high number of deaths and infected people. To contain the diffusion of COVID-19 virus, governments have enforced restrictions on outdoor activities or even collective quarantine on the population. Quarantine carries some long-term effects on cardiovascular disease, mainly related to unhealthy lifestyle and anxiety
Theory of photon-driven correlated electrons in one dimension
Full text linkIn this paper we present a general theoretical framework to study interacting electrons under the influence of an external time-periodic driving, such as a homogeneous laser field. This is performed through a true many-body calculation and the use of Floquet theory. In particular, we consider a linear atomic chain using the Hubbard model to describe the short-ranged Coulomb interactions between electrons, plus Cluster Perturbation Theory to embed the many-body exact solution for a finite system into both an extended and an infinite lattice. Due to the presence of the external time-periodic perturbation, the electronic problem can be mapped into the study of photon-dressed quasiparticles thanks to Floquet theorem, keeping into account of all the virtual processes (absorption and emission of photons by electrons) with the laser field. This leads to an extension of the many-body static theories to out-of-equilibrium systems. This theoretical approach allowed us to show how the electronic properties of the system can be controlled and tuned varying the laser parameters. Above all, an inverse insulator-to-metal transition can be obtained for the one dimensional infinite lattice, and edge localized states appear as a finite size effect in an extended truncated chain

The SILVER study. Efficacy of topical nitric-zinc complex solution in the treatment of resistant warts: A postmarketing evaluation
Full text linkThe treatment of cutaneous viral warts caused by human papillomavirus (HPV) infection is often subject to local recurrence and a long clinical and treatment course. Our aim was to analyze real-life data on the treatment of difficult-to-treat warts from a multicenter postmarketing surveillance assessment on the efficacy, tolerability, and safety of a commercially available nitric-zinc complex solution (NZCS). Dermatologists from 14 Italian centers completed a questionnaire about their clinical experience on treatment of “difficult-to-treat” warts, which included warts in the plantar, periungual, anogenital and aesthetically sensitive areas. The questionnaire was designed to obtain detailed information on wart treatment and compare NZCS efficacy with previous treatments. Of 106 questionnaires returned, 83 reported NZCS use; 67 had previous treatments (23 cryotherapy, 2 electrocoagulation, 12 other topical application, and 30 combined treatment, such as laser, cryotherapy, and/or electrocoagulation). NZCS had superior efficacy to that of previous treatments (p <.0001), resulting in 84.1% with a full or partial clearance (vs. 44.8% for previous treatments), and had better local tolerability (p <.0001). NZCS showed better efficacy and tolerability than other previous wart treatments
