RISKS OF DISREGARDING THE INCOMPATIBLE TRINITY RULE: THE SWISS FRANC CRISIS CASE
2015
When designing economic policies, governments must take account not only of economic laws but also of certain rules of thumb. The incompatible trinity is such rule, which states that a country cannot simultaneously have a fixed exchange rate regime, mobility of foreign capital and an independent monetary policy. Traditionally, the rule has been generally observed, whether knowingly or not. The recent crisis triggered by the removal of cap on the Swiss franc is an illustrative example of what might happen if the said rule is disregarded.
La fides e la promessa: forme di reciprocità tra dèi e uomini nella riscrittura di Ovidio
2017
Nelle rielaborazioni ovidiane dei racconti mitici greci, emergono diversi casi in cui la relazione tra esseri umani e divinità è riscritta alla luce della nozione romana di fides. Ma se la quasi totalità di questi miti, in cui il dio promette all’interagente mortale un pegno, un dono o un privilegio, è giustificata dalla presenza di vincoli di tipo amoroso, parentale o devozionale, un caso a parte rappresenta il racconto di Numa Pompilio e Giove (Fast. 3. 285-392) – un racconto Romano – in cui l’agente umano merita i pignora certa del dio e instaura con lui un rapporto di reciprocità. Il contributo si propone di esaminare questa rappresentazione della fides pollicita attraverso un confronto…
Syntaxonomic survey of the class Pegano harmalae‐Salsoletea vermiculatae Br.‐Bl. & O. Bolos 1958 in Italy
2013
After a general outline on the syntaxonomical framework of the class Pegano harmalae-Salsoletea vermiculatae Br.-Bl. & O. Bolos 1958, the occurrence of this vegetation in the Italian territory is examined. In Italy, this vegetation is mostly found on clayish or marly substrata, particularly if slightly enriched with nitrates and chlorides. With reference to the Rivas-Martinez bioclimatic classification, the Italian stands have an infra- to thermo-Mediterranean thermotype (marginally up to the meso-Mediterranean one) with dry or arid ombrotype. In particular, this vegetation is well represented in Sicily, while in Sardinia and along the Italian Peninsula, it progressively becomes more rare a…
Synthesis of a biocompatible aerogel based on graphene oxide and a modified polyethylene glycol
2016
The synthesis and self-assembly of a 3D aerogel built by graphene oxide (GO) and a modified polyethylene glycol (PEG) was achieved by a multi-step synthetic procedure, involving the preparation of an amino-terminated PEG (PEG-NH2) and the subsequent coupling with GO by carbodiimide in water, exploiting the carboxyl and epoxy moieties of GO and –NH2 terminations of the biopolymer. The resulting nanohybrid hydrogel was successively converted into an aerogel via dialysis plus freeze-drying [1] and fully characterized. FTIR, Raman, XPS, XRD and BET measurements were performed to confirm the successful modification for each reaction step, while morphological, mechanical and hemolytic tests were …
Physicochemical Properties of A New PEGylated Polybenzofulvene Brush for Drug Encapsulation
2019
A new polymer brush was synthesized by spontaneous polymerization of benzofulvene macromonomer 6-MOEG-9-T-BF3k bearing a nona(ethylene glycol) side chain linked to the 3-phenylindene scaffold by means of a triazole heterocycle. The polymer structure was studied by SEC-MALS, NMR spectroscopy, and MALDI-TOF MS techniques, and the results supported the role of oligomeric initiatory species in the spontaneous polymerization of polybenzofulvene derivatives. The aggregation features of high molecular weight poly-6-MOEG-9-T-BF3k-FE were investigated by pyrene fluorescence analysis, dynamic light scattering studies, and transmission electron microscopy, which suggested a tendency towards the format…
Allergy to Polyethilenglicole of Anti-SARS CoV2 Vaccine Recipient: A Case Report of Young Adult Recipient and the Management of Future Exposure to SA…
2021
The main contraindication to the anti-SARS CoV2 vaccine is an anaphylactic reaction to a vaccine component. The need to vaccinate allergic people who are at higher risk can be of public health interest and this report shows a case of an allergic reaction to PEG of a HCW who had received the first dose of anti-SARS CoV2 vaccine. For 5 h after the administration of the vaccine, she had the appearance of erythematous spots on the face and neck, and a feeling of a slurred mouth and hoarseness. In order to treat the event, she was administered 8 mg intravenous dexamethasone, 1 vial intravenous chlorphenamine maleate, 250 mL intravenous 0.9% NaCl, and conventional oxygen therapy (2 L/min) with co…
Intravitreal anti-vascular endothelial growth factors, panretinal photocoagulation and combined treatment for proliferative diabetic retinopathy: a s…
2020
Purpose: to conduct a systematic review with network meta‐analysis (NMA) of randomized clinical trials (RCTs) comparing panretinal photocoagulation (PRP) versus anti‐vascular endothelial growth factor (VEGF) treatment alone or in combination with PRP, for proliferative diabetic retinopathy (PDR).Methods: PubMed, Medline and Embase databases were searched for RCTs comparing PRP versus intravitreal anti‐VEGF therapy and/or combined PRP and intravitreal anti‐VEGF for PDR. The primary outcome measures were the mean best corrected visual acuity (BCVA) change and the regression of neovascularization. Mean change of central macular thickness (CMT), the subgroup analyses of patients without diabeti…

Intravitreal Pegaptanib in Ischemic CRVO Refractory Exudative Macular Detachment
2012
Abstract Recent literature data reported evidence of the visual and/or anatomical benefits of all clinically available anti-VEGF drugs for the treatment of macular edema (ME) following Central Retinal Vein Occlusion (CRVO), up to 1-year followup. There are no randomized clinical trial data on anti-VEGF agents in ischemic CRVO-ME and the use of anti-VEGF agents to treat this condition. A 73-year old caucasian man, with a medical history of diabetes and systemic hypertension and an ophthalmic history of ischemic CRVO with cystoid macular edema was referred to our division on January 2011. The ophthalmic examination showed in right eye a visual acuity of 20/2000, a C2N1 cataract and an exudati…
Standard Therapeutic Approach and New Therapies
2015
The traditional approach to therapy of Crohn’s disease has been the step-up approach usually represented as a pyramid (Fig. 7.1) where, progressing from mild to severe disease, therapeutic choices proceed step by step from less potent drugs at the basement of the pyramid to more potent but also more toxic drugs at the top. The advent of biological therapies and the wider use of immunomodulators, together with the opportunity to achieve ambitious treatment goals and possibly to modify the course of disease, have led to other approaches such as the accelerated step-up or the top-down approach. This means that immunomodulators and biologics can be used earlier and de-escalated when disease is …
